    Detailed Description [0011] Most crop production is carried out by sowing an entire field with a variety of seed. However, sufficient agronomic data is now available to use site-specific planting recommendations, which use two or more varieties of seeds in a given field to increase yields. Several factors are used to determine the best variety for a given location. One area of a field may be lower and typically more humid than other areas. The increased humidity alone may suggest a different variety at that location. In addition, moisture can result in an increase in weeds or pressure from pests in that location, requiring other varieties with resistance to these pressures. To plant the field more efficiently with parallel passes back and forth, and to plant with several varieties specific to the location, it is necessary to switch back and forth between varieties numerous times, based on the location of the machine in the field.
    [0012] With reference to figure 1, a planting machine in the form of a line planting planter 20 is shown, which is capable of switching between seed varieties without stopping the machine. Planter 20 is equipped with several row 22 planting units, only one of which is shown. Online unit 22 is just one example of several different types of online units that can be used to plant seeds. The inline unit 22, as shown, includes an opener 24 that forms a shallow groove in the ground when the machine crosses a field. Gauge wheels 26 control the depth of the groove. A seed doser 28 doses seeds to sequentially distribute individual seeds to a seed tube 30 that directs the seeds into the groove below the doser. A closing wheel or other device 32 tracks back and covers the deposited seed with soil. Each line unit 22 is mounted to the machine frame 34 by means of a parallel link 56 (figure 1) so that the individual line units 22 can move up and down to a limited degree relative to the frame 34. Various Line units 22 are mounted to frame 34, such that several parallel lines are planted with each pass of the machine through a field.
    [0013] Each seed dispenser is equipped with a small seed hopper 40, commonly referred to as a mini hopper. Seed from two or more tanks 42, 44 is distributed pneumatically to the mini hopper through tubes 46, 48. Tube 46 extends from tank 42 to mini hopper 40 and tube 48 extends to from tank 44 to mini hopper 40. Each tank 42, 44 carries a different variety of seed, such that each variety is distributed to each mini hopper. The tanks and tubes are part of a pneumatic seed delivery system 50, such as those shown in US Patents 6,609,468; 6,688,244 and 7,025,010, incorporated herein by reference. The seed distribution system also includes a fan, or fans, 52 to provide the air flow to transport the seeds through tubes 46, 48.
    [0014] Line unit 22 and seed doser 28 are shown in greater detail in figures 2 and 3, with the line unit in which the components are arranged differently than shown in figure 1, but with the same components essential. Each line unit 22 has a frame member 58 (figure 2) to which the components of the line unit are mounted. The frame member 58 includes a pair of vertical arms 60 at its front end. The arms 60 are coupled to the rear-facing ends of the parallel joint 56. Grooving discs 24 are connected to the shaft 62 in a known manner to form a groove cut in the soil below the planting machine, into which the seed is deposited. A seed doser 28 and a seed distribution system 400 are also attached to the frame member 58 of each line unit. The seed distribution system 400 replaces the seed tube 30 of figure 1.
    [0015] The dispenser 28 includes a housing 64 (figure 3) consisting of a housing body 66 and a cover 68. The housing body 66 and the cover 68 are coupled to each other by means of complementary articulation aspects 70 and 72 on the housing and cover body, respectively. The articulation aspect 70 includes a pivot pin 71 (figure 4) coupled to the housing body, while aspect 72 is a hook formed in an integrated manner that wraps around the pivot pin 71 allowing the cover 68 to pivot around the geometric axis of the pin . An elastomeric locking member 74 is coupled to the housing body 66 and has an enlarged portion 76 which is seated in a socket 78 formed in the cover to maintain the cover in a closed position on the housing body 66.
    [0016] The housing body 66 is formed with a second articulation element in the form of a pivot pin 80 (figure 3). The pivot pin 80 is seated on a hook member 82 of the mounting frame 84 attached to the frame member 58. This allows the seed feeder 28 to pivot in relation to the line unit frame member 58 around a geometric axis 86 A drive spindle 90 (figure 4) is loaded by the housing body 66 and has a drive hub 92 on its end. The spindle 90 couples to the output shaft 94 of the electric motor 96 to drive the seed dispenser when in the assembled position shown in figure 3. The seed dispenser 28 is coupled to the distribution system 400 by a locking mechanism 100 that includes a stem of metal 102 having a hook at one end seated in an opening in the dosing housing body 66 when locked. The distribution system still has an assembly hook 104, shown partially in figure 2, which attaches to the planting unit frame member 58 to support the distribution system. The distribution system 400 is driven by an electric motor 106 also loaded by the mounting frame 84. The output shaft of the motor 106 is connected to the distribution system via a right-angle drive 108.
    [0017] A dosing member 110 is placed inside the dosing housing 64. The dosing member 110 has a single body piece shaped into a concave bowl. The cup-shaped body has a base portion 116 from which a side wall 114 extends. The side wall 114 ends at an outer edge 116. Next to the outer edge 116 there is an annular opening system 118 that extends through the wall side. The base portion 112 of the dosing member contains a central drive opening 130 (figure 4) used to mount the dosing member on the rotating drive hub 92 for rotation around the axis 132. In operation, when the dosing member rotates, individual seeds from a seed pool, located adjacent to the inner side of the dosing member, are adhered to the openings 118 and carried in sequence upwards to a release position, where the seeds are removed individually by the 400 distribution system. doser doses thus, that is, it distributes individual seeds at a controlled rate from the doser.
    [0018] The mini hopper 40 is shown in greater detail in figures 5 and 6, where the hopper body is shown without the removable cover, or ventilation screens. The interior of the hopper is divided in two by a wall 120, forming two chambers 122 and 124. Seed hose 46 from the tank 42 passes into the hopper and ends in the chamber 122, so seed from the tank 42 it is deposited in chamber 122. Likewise, hose 48 passes into the hopper and ends in chamber 124 to deposit seeds in it. At the lower end the hopper includes a seed trough or conduit portion 126, which is divided by the wall 120 into two seed passages 128 and 130 which are at the lower ends of chambers 122 and 124, respectively. The hopper connects to the dosing housing 66 at the opening 132 in the housing with the chute portion 126 that extends into the housing housing. Although the hopper is shown as a single piece of plastic molding with a chute that has two seed passages, it will be appreciated that separate hoppers for the two seeds are possible, and separate conduits, each forming a seed pass, are also possible. In addition, with separate ducts or rails the housing body 66 could have two separate openings in it for the seed passages. The claims that follow should be widely interpreted to cover these variations.
    [0019] A one-piece barrier 150 (figure 8) is mounted in the housing and movable to various positions to close or open the ends of the seed passages 128, 130. The barrier 150 includes a portion of hub 152 that mounts the barrier on the dosing housing for rotation substantially around the dosing geometry axis 132. The hub portion includes an opening 154 which fits over an annular rib 156 over a bushing 158 (figure 7). As shown in figures 7 and 8, the rib is concentric around the dosing geometric axis 132 but it does not have to be that way. It is possible that the axis of rotation of the barrier 150 is different from the axis 132, if desired.
    [0020] Barrier 150 has a first radial arm portion 160 that extends radially from the hub portion 152. Connected to the first radial arm portion is a blade portion 162. In the embodiment shown in figure 8 the blade portion includes two portions walls 164 and 166 separated by a window 170. The barrier still has a second arm portion radially 172 with a slot 174. A crank or joint 176 formed of a metal rod is rotatably mounted to the housing body 66 by a bushing 178 fitted into the housing body. The end of one arm 180 of the crank is placed in slot 174. The end of the other arm 182 of the crank is located on the outside of the dosing housing and is coupled to a linear actuator 184 attached to the outside of the housing body 66.
    [0021] The hub portion 152, the first radial arm portion 160, and the second radial arm portion 172, are all generically on the same plane. The blade portion 162 is inclined to the common plane of the hub portion and the radial arms. The paddle portion is shaped like a portion of a cone trunk and generally corresponds to the contours of the inside of the dosing member 110.
    [0022] Operation of the linear actuator to extend or retract the plunger 186 causes the crank to rotate around the geometric axis 188 defined by the bushing 178. Rotation of the crank in turn causes the barrier to rotate around its geometric axis of rotation, moving the wall portions to different locations to open or close passages 128 and 130 into the dosing housing. The linear actuator can be electronic, hydraulic, pneumatic, etc. The type of linear actuator is not critical for the operation of the seed dispenser.
    [0023] The brushes 190, 192 and 194 on the bottom edges of the hopper 40 form seals between the hopper and the portion 162 of the barrier 150 to keep seeds in the seed passages 128 and 130 as to mix with each other and as to move to other areas inside the dosing housing. A brush 196 mounted on the wall portion 166 of the adjacent barrier and below the windows 170 forms a seal between the barrier 150 and the surface of the dosing member 110. The brushes have a plurality of closely spaced flexible bristles that are carefully packaged to resist the passage of seeds through the brushes. The brush could be made with a single piece of flexible material forming a scraper that engages and drags on the surface of the blade to form a seal.
    [0024] With reference to figure 8, the barrier 150 is in a position where the wall portion 164 covers and closes the seed passage 128. This prevents seeds from passage 128 as to flow into the dosing housing. The window 170 is aligned with the seed passage 130, allowing seeds from the passage 130 to flow into the dosing housing and form a small pool of seeds in contact with the surface of the dosing member 110. Brush 196 defines a limit bottom of the seed pool and keeps seeds from moving down beyond the windows 170 to the bottom of the housing body.
    [0025] The operation of the actuator 184 to retract the plunger 186 causes counterclockwise rotation of the crank around the geometric axis 188 as seen in figure 8. This causes the barrier 150 to rotate hourly by moving the window 170 to align with the seed passage 128, while moving the wall portion 166 to align with the passage 130, thereby dosing the passage with 130 as shown in figure 9. When rotating the barrier, any seed in the seed pool beyond the paddle portion 162 of the barrier it is pushed upwards by brush 196 and remains in the seed pool and is mixed with seeds from passage 128. The amount of seeds from passage 130 mixed with seeds from passage 128 will be relatively small. In the same way, when the barrier is moved in the opposite direction to move the window from the seed passage 128 to the seed passage 130, seeds from the passage 128 in the seed pool will move down and mix with seeds from the passage 130.
    [0026] The operation of actuator 184 is controlled by a control system, not shown, which uses a seed recommendation that defines where each of the seed varieties should be planted in the field. A location system, such as a GPS system, determines the location of the machine in the field and then operates the actuator 184 to supply seeds from seed passage 128, or seed passage 130, to the dosing member 110 for planting at that location.
    [0027] An alternative embodiment of the barrier is shown in figure 9 with a barrier 250. The barrier 250 has a hub portion 152, a first radial arm portion 160 and a second radial arm portion 172 as the barrier 150. The barrier 250 differs in that the blade portion 262 only has a wall portion 264 and no window portion. The single wall portion 264 moves between a first position covering the seed passage 128 to close that passage, while the seed passage 130 is open, and a second position (shown in figure 10) in which the wall portion covers and closes the seed passage. seed passage 130 while seed passage 128 is open. There is no brush below the open seed path to contain the seed in the seed pool. The seed pool will be located at the bottom of housing 66.
    [0028] A third embodiment is shown in figures 11 to 13. There, barrier 350 has a hub portion 152, a first portion of radial arm 160 and a second portion of radial arm 172 as barriers 150 and 250. The portion of shovel 362 has a single wall portion 364 and no window. The wall portion 364 is large enough to close both seed passages 128 and 130 simultaneously as shown in figure 13. Barrier 350 is movable to another position shown in figure 11, in which seed pass 128 is open and the passage is open. seed 130 is closed. In yet another position, the barrier closes the seed path 128 and opens the seed path 130, as shown in figure 12. To move from the position shown in figure 12 with the seed path 130 open, to the position shown in figure 11 with the seed passage 128 open, the wall portion should move through the position shown in figure 13, in which both seed passages 128 and 130 are closed. In this position, seed in the seed pool in the dosing housing can be used substantially before opening another seed passage. This reduces the amount of seed mixture from both passages. Barrier 350 thus has three positions, one position that opens a first seed pass and closes a second seed pass, a second position that opens the second seed pass and closes the first seed pass, and a third position that closes both the first and second seed passages. This is done with a barrier located in the dosing housing, thus eliminating the need to pack the barrier outside the dosing housing where it can interfere with other components on the line unit.
    [0029] Having described the seed and barrier doser, it will become evident that several modifications can be made without departing from the scope of the invention as defined in the accompanying claims.
