    Field of Invention
    [001] This invention refers to belt collectors for agricultural combined. Fundamentals of the Invention
    [002] Combined agricultural belt collectors are agricultural harvesting heads that collect previously cut crop plants that have been stacked. They include an endless conveyor belt extending from the front of the belt collector that lifts the windrow and feeds it back into the feed chamber of a combined farm.
    [003] The agglomerates vary in their height and density depending on the volume of the crop that was harvested and gathered. As a result of this variation, the feed chamber conveyor in the combined farm occasionally gets stuck with excess cut crop material.
    [004] When the feed chamber is jammed in this way, the operator stops moving ahead of the combination and reverses the feed chamber conveyor to eject the cut cultivating material slug that jams the feed chamber conveyor. This sends the agglomerate forward and deposits it back into the belt collector.
    [005] Once the agglomerate has been ejected, the operator restarts the feed chamber conveyor and the endless conveyor belt of the belt collector.
    [006] One problem with this arrangement is that the cut cultivated agglomerate material is occasionally pulled back into the feed chamber and jams the feed chamber again. At this point, the operator will repeat the process of clearing the conveyor from the feed chamber. If the cluster is particularly large and this does not work, the operator may have to eject the cluster, step down from the operator's cab and remove the cluster from the belt collector. This is a time-consuming process.
    [007] What is needed, therefore, is an improved system to unclog a feed chamber and a belt collector. It is an object of this invention to provide such a system. Invention Summary

    [0016] The step of operating may comprise the steps of not moving the first belt conveyor for a first portion of the first time delay interval; and accelerating the first conveyor belt in a first crop direction to its normal crop speed for a second portion of the first time delay interval.
    [0017] In the first time delay the interval can be between 10 and 60 seconds.

    [0023] Figure 3 is an operational flowchart of the system to unclog the feed chamber and belt collector. Description of Preferred Modalities
    [0024] The term "ECU" as used herein means a single ECU, or a plurality of ECUs connected together in a network to perform the functions described herein.
    [0025] In Figure 1, a belt collector 100 is supported at the front end of the feed chamber 102 of an agricultural combination 104. The belt collector 100 comprises a frame 106, which supports a collection conveyor 109, a transfer conveyor 111, and an endless conveyor 112.
    [0026] The combined agricultural 104 takes the belt collector 100 across the field in the “V” direction. The collection conveyor 109 contacts the slug of cut cultivation material, lifts it, and carries it back.
    [0027] The collection conveyor 109 deposits the cut cultivation material onto the transfer conveyor 111, which carries the cut cultivation backwards. The transfer conveyor 111 deposits the cut cultivation material onto the endless conveyor 112.
    [0028] The endless conveyor 112 takes the cut cultivation material laterally inward from the sides of the belt collector 100 to the center of the belt collector 100, and then feeds the cut culture material through a hole 211 (Figure 2 ) in the frame of the belt collector 100 and to the inlet of the feed chamber 102.
    [0029] A belt conveyor 114 in the feed chamber 102 carries the cut crop up and back to a drum conveyor 116, which then transports the cut crop to a threshing and separation system 118 where grain in the cut crop material it is threshed and separated from the non-grain material.
    [0030] An additional conveyor (not shown) takes the now cleaned grain up to a grain tank 120 at the blender 104 from where it can be periodically transferred to a vehicle (not shown) which moves laterally to the blender 104.
    [0031] An operator cabin 122 is arranged above and behind the belt collector. Operator cabin 122 has an operator seat and multiple operator controls to allow the operator to operate the agricultural combo 104 and belt collector 100.
    [0032] Referring to Figure 2, the collection conveyor 109 comprises an endless collecting belt 108 which is supported for recirculating movement around a idler roller 200 and a drive roller 202. The collecting belt 108 is made of a cloth impregnated with vulcanized rubber to which small steel fingers were attached. These fingers extend outward from the collection belt 108 and pick up the agglomerate being collected.
    [0033] The drive roller 202 is coupled and driven by a drive motor 204, shown here as a hydraulic motor.
    [0034] The transfer conveyor 111 comprises an endless conveyor belt 110 that is supported for recirculating movement around a idler roller 206 and a drive roller 208. The drive roller 208 is coupled and driven by a drive motor 210, shown here as a hydraulic motor.
    [0035] The drive rollers and idler rollers of the collection conveyor 109 and the transfer conveyor 111 are supported on the frame 106, which allows them to rotate around their longitudinal geometric axes with respect to the frame 106.
    [0036] The endless conveyor 112 includes an elongated cylinder 212 on which spiral conveyor pallets 214 are fixed at each end. Elongated cylinder 212 is supported at each end on frame 106 such that it can rotate with respect to frame 106.
    [0037] When the endless conveyor 112 rotates in a forward direction to harvest crops, the spiral conveyor pallets 214 contact the cut crop material received from the rear portion of the conveyor belt 110 and transport that cut crop material inward from both ends of the elongated cylinder 212 toward a midpoint of the elongated cylinder 212. The endless conveyor 112 then pushes the cut cultivation material through a hole 211 in the frame 106 where it is received by the conveyor. of belt 114 in feed chamber 102.
    [0038] When the endless conveyor 112 is driven in a reverse direction, the cut cultivation material flows in a direction opposite to that described in the previous paragraph. The endless conveyor 112 pushes crop material cut through the hole 211 in the frame 106 and deposits it on the rear portion of the conveyor belt 110.
    [0039] A pulley 216 is fixed to the elongated cylinder 212 to set the endless conveyor 112 in rotation. The pulley 216 is driven by an endless belt 218, which is wound around the pulley 216. The endless belt 218 is wound and driven by a second pulley 220. The second pulley 220 is fixed to a shaft 222 which is driven by another belt and pulley arrangement 224 connected to a variable speed drive 226. The belt and pulley arrangement 224 is also coupled and drives the belt conveyor 114 which is disposed within the feed chamber 102.
    [0040] The belt conveyor 114 in the feed chamber 102 comprises a idler roller 228, a drive roller 230, and an endless belt 232. The ends of the two rollers are supported on the side walls of the feed chamber 102 to rotate with respect to the feed chamber 102. The drive roller 230 is rotated by the belt and pulley arrangement 224. When the belt conveyor 114 is driven in a forward direction to harvest crops, cut crop material is received from the endless conveyor 112 through hole 11 and under drive roller 230.
    [0041] In a common arrangement, the endless belt 232 comprises two endless chains on which laterally extending strips are attached, and the drive roller and idler rollers comprise sprockets mounted on shafts that contact and drive the two endless chains.
    [0042] The variable speed drive 226 is electrically coupled to an ECU 234. The ECU 234 includes at least one digital microprocessor, an internal memory to store program instructions and work variables for the digital microprocessor, and drive circuitry to control the valve 236 and the variable speed drive 226. The variable speed drive 226 may be a gearbox, a continuously variable transmission, or other mechanical or electrical device in which the direction (and preferably the speed) of the output shaft 248 can be varied by controlling the ECU 234.
    [0043] The pulley 216, the belt 218, the pulley 220, the shaft 222, the belt and pulley arrangement 224, the variable speed drive 226, and the belt and pulley arrangement 244 constitute a variable drive that couples the motor 242 on the belt conveyor 114 and the endless conveyor 112 to drive the belt conveyor 114 and the endless conveyor 112 bidirectionally (and preferably at a plurality of speeds selectable by the ECU).
    [0044] The ECU 234 is coupled to a first operator input device 238, and a second operator input device 240. These operator input devices are configured to be manipulated by the operator and generate operator signals. These operator signals are communicated to the ECU 234.
    [0045] In this way, the operator can signal the ECU 234 as the ECU 234 should control the valve 236 and the variable speed drive 226 according to the pre-programmed digital instructions that are stored in the ECU 234, and which will be described with more details together with Figure 3.
    [0046] Operator input devices may comprise touch screens, buttons, switches, dials, levers, potentiometers, shaft encoders, variable resistors, or the like.
    [0047] An internal combustion type engine 242 is driveably coupled to variable speed drive 226. They are coupled by a belt and pulley arrangement 244. Engine 242 drives input shaft 246 of variable speed drive 226, which (by means of a sequence of internal gears) drives output shaft 248 of variable speed drive 226. Output shaft 248 can be selectively engaged, disengaged, driven in a first direction of rotation, driven in a second direction of rotation. rotation opposite the first direction of rotation, and driven at a plurality of speeds in both directions. This operation is controlled by the signals received from the ECU 234.
    [0048] The variable speed drive 226 is connected and drives both the belt conveyor 114 in the feed chamber and the endless conveyor 112. "Synchronized" as used which means that whenever one of the two conveyors is driven in one forward direction, the other is similarly driven in a forward direction whenever one of the two conveyors is driven in a reverse direction, the other is similarly driven in the reverse direction whenever one of the conveyors is accelerated or decelerated, the other conveyor similarly speeds up or slows down. In the arrangement illustrated here, the speeds of the two conveyors may differ, but they differ proportionally.
    [0049] Thus, when the ECU 234 controls the speed and direction of one of the belt conveyors 114 on the endless conveyor 112, it equally controls the speed and direction of the other conveyor.
    [0050] Valve 236 is coupled to ECU 234 and is actuated by ECU 234. Valve 236 is a proportional control hydraulic valve capable of selectively establishing and controlling both the speed and direction of fluid flow through the hydraulic motor 204 and the hydraulic motor 210 in response to signals received from ECU 234. Hydraulic motor 204 and hydraulic motor 210 are connected in a hydraulic circuit in series with each other and with valve 236. Both hydraulic motors move in the same direction (both direct and reverse) and at the same speeds (or proportional speeds).
    [0051] Figure 3 illustrates a preferred mode of operation of the ECU 234. It illustrates a programmed loop that is periodically executed several times per second when the agricultural combination 104 is shifting in the field harvesting crops. This programmed loop is stored in the form of digital instructions in the memory circuits of the ECU 234.
    [0052] At the beginning of the loop in step 300 the ECU 234 reads a signal from the operator's first input device 238 to determine if the operator manipulated it.
    [0053] In step 302, the ECU determines from the signal from the operator's input device 238 if the operator has requested that the belt collector 100 be turned off.
    [0054] If the ECU 234 determines that the answer is "yes" in step 302 (that is, the operator has requested that the belt collector 100 be turned off), the ECU continues to step 304 in which it signals valve 236 to stop the flow of hydraulic fluid through the hydraulic motors 204 and 210, to thereby stop the motors, and the collection conveyor 109 and transfer conveyor 111 which are driven by the motors. The ECU 234 also signals the variable speed drive 226 to stop rotating the output shaft 248, and thereby stop the auger 112 and the belt conveyor 114.
    [0055] If the ECU 234 determines that the answer is “no” in step 302 (ie the operator does not request the belt collector 100 to be turned off) the ECU then goes to step 306.
    [0056] In step 306, the ECU 234 determines from the signal whether the operator has requested that the belt collector 100 be inverted. The operator does this when the belt conveyor 114 in the feed chamber has jammed with a slug of cut cultivating material.
    [0057] If the ECU 234 determines that the answer is “yes” in step 306 (i.e. the operator requested that the belt collector 100 be inverted), the ECU then continues to step 308 in which it signals valve 236 to stopping the hydraulic motors 204 and 210 and thereby stopping the collection conveyor 109 and the transfer conveyor 111. The ECU also signals the variable speed drive 226 to reverse the endless conveyor 112 and the belt conveyor 114. causes variable speed drive 226 to begin moving belt conveyor 114 and endless conveyor 112 in a reverse direction of rotation. This sends the cut cultivating material slug that is clogging the feed chamber 102 to the endless conveyor 112, then through the endless conveyor 112, and then deposits the cut cultivating material slug on the exit portion of the belt. carrier 110 (which stopped).
    [0058] If the ECU 234 determines that the answer is “no” in step 306 (that is, the operator has not requested that the belt collector 100 be inverted), the ECU continues to step 310.
    [0059] In step 310, the ECU 234 determines whether the signal from the operator input device 238 indicates that the operator has requested that the belt collector 100 be operated in a forward direction (i.e., in a direction to harvest crops ).
    [0060] If ECU 234 determines that the answer is “yes” in step 310 (ie the operator has now requested that belt collector 100 be operated in a forward direction), ECU 234 continues to step 312.
    [0061] In step 312, the ECU 234 sequences the start of the collecting belt 108, the conveyor belt 110, the endless conveyor 112 and the belt conveyor 114 as follows.
    [0062] In step 312, the ECU 234 first starts the endless conveyor 112 and the belt conveyor 114 in the feed chamber 102 turning in a forward direction. For a typical 104 agricultural combination, the two conveyors reach full harvest speed in 2-5 seconds.
    [0063] The ECU 234 does not immediately start collecting belt 108 and conveyor belt 110, however. Instead, the ECU 234 delays the start of the collecting belt 108 and conveyor belt 110 for a short period of time, on the order of 10-60 seconds. The short period of time depends on the type of grow material being harvested, the size of a typical clump of that grow material, and the specific dimensions of the belt collector 100.
    [0064] As the inventors have discovered, one of the primary problems causing the belt conveyor 114 in the feed chamber 102 to become completely bogged down again is the fact that the cut crop material agglomerate is ejected onto the conveyor belt 110 (in step 308) is fed back very quickly to the endless conveyor 112 and the belt conveyor 114 in the feed chamber 102.
    [0065] By delaying the start-up of the collecting belt 108 and the conveyor belt 110, the cut cultivated material agglomerate can be separated by the endless conveyor 112 and be gradually fed into the feed chamber 102 at a rate that does not cause the supply chamber 102 is immediately clogged again.
    [0066] Third, after the initial start delay of the collecting belt 108 and the conveyor belt 110, the ECU 234 automatically increases the speed of the collecting belt 108 and the conveyor belt 110 to the full harvest speed.
    [0067] There are several ways in which the ECU 234 can delay the start of the collecting belt 108 and the conveyor belt 110.
    [0068] In a configuration of step 312, the ECU 234 keeps the collecting belt 108 and the conveyor belt 110 stopped for a first predetermined period of time (on the order of 10-30 seconds), which is typically several seconds after the conveyor auger 112 and the belt conveyor 114 have reached full operating speed. The ECU 234 then gradually accelerates the collecting belt 108 and conveyor belt 110 in a forward direction for a second predetermined period of time (on the order of 10-30 seconds) until the collecting belt 108 and conveyor belt 110 reach the total harvest speed.
    [0069] In another configuration of step 312, the ECU 234 can start the collection conveyor 109 and the transfer conveyor 111 operating in a forward direction at a very reduced speed such that the conveyor belt 110 feeds very slowly the agglomerate of cultivating material cut on the endless conveyor 112 to fragment. At this very reduced conveyor belt speed, on the order of a few inches per second, the endless conveyor 112 will still shred the cut crop material agglomerate, but at a slightly higher rate it would shred the cut crop material agglomerate if the conveyor belt 110 was completely stopped.
    [0070] If the conveyor belt 110 is completely stopped in step 312 for an initial predetermined time interval as in the first configuration, or if it slowly advances forward at a very low speed that gradually increases as in the second configuration, the benefit is the even: by preventing the conveyor belt 110 from operating at full operational speed ahead immediately, the endless conveyor 112 has time to separate the cut crop material agglomerate and feed it more gradually into the feed chamber 102, and feed it slower, significantly reduces the likelihood that the feed chamber 102 will immediately become completely jammed again.
    [0071] From time to time, the agglomerate of cut cultivation material that has previously been jammed in the feed chamber and has been ejected from the endless conveyor 112 may be quite small, or it may be fragmented very quickly.
    [0072] In this case, there is no reason for the operator to continue the gradual start-up of the collection conveyor 109 and the transfer conveyor 111. Instead, the operator would prefer to bring both conveyors to full speed as quickly as possible.
    [0073] To provide this ability to abort the soft staggered start performed in step 312, ECU 234 is programmed to respond to operator input device 240 as ECU 234 performs the staggered start process of step 312.
    [0074] If the operator manipulates the operator's second input device 240 while the ECU 234 is performing step 312, the ECU 234 is configured to immediately accelerate the collection conveyor 109 and the transfer conveyor 111 to full harvest speed without delay.
    [0075] The claims define the invention, which is not limited to the specific embodiment or embodiments described herein. Obvious variations from the specific modality shown here will be apparent to those skilled in the art.
    [0076] For example, instead of the variable speed drive arrangement, belts, pulleys, internal combustion engine to provide bidirectional rotary motion at variable speeds, one or more hydraulic motors can be provided. Multiple belts with multiple pulleys of varying diameters can be selectively tensioned and released in order to change the speed and/or direction of the conveyors. Multiple hydraulic or electric motors operating in different directions can be selectively used and removed and their speed changed by proportional control valves and electric drive circuits to provide both variable speed control and steering control. Additionally, these motors can be connected directly to conveyors. A single hydraulic motor that can be driven bidirectionally at variable speed can be coupled to the conveyors.
    [0077] As another example, the collecting belt and the conveyor belt can be driven by pulley and belt arrangements (which include ratchet and chain arrangements) coupled to electric or hydraulic motors. Instead of two motors, one motor (electric or hydraulic) can be coupled to either the collecting belt or the conveyor belt to drive them simultaneously.
