    An agricultural-machine intake has a frame adapted to travel along the ground in a travel direction, a transverse feeder fixed extending horizontally and transversely to the direction on the frame, a pair of end mounts on the frame and a center mount transversely flanked thereby, supports carrying the mounts on the frame for up and down movement generally tangential of the transverse feeder, and a jointed reel centered on and rotatable about at least one horizontal reel axis extending transverse to the direction through the mounts. The reel has outer ends journaled in the end mounts, a jointed center journaled in the center mount and axially subdividing the reel into two halves, and radially extending tines. Respective ground-engaging end and center skids are vertically displaceable on the frame. Respective end and center links connect the end and center skids to the respective mounts for synchronous vertical movement of the skids with the respective mounts. A drive rotates the reel about the reel axis and thereby picks crop up off the ground. An array of strippers fixed on the frame spacedly surrounds the reel between the tines. Thus the picked-up crop is pulled off the tines by the strippers.

    专利说明:

    The invention relates to agricultural machinery industry, namely to pick-ups for self-propelled harvesting machines with a large working width, with soil coping with pick-up drums in the pick-up in order to achieve the least losses when harvesting agricultural crops in rolls or widely spread for quick drying.
    The pick-up is known (GDR Patent No. 12890, class A 01 D 89/00, 12/14/77) for self-propelled agricultural machines, which, having a large pickup width, selects the unfolded agricultural crop. At the same time on the pick-up with adjustable height, having a rigid tray and a cross transport auger, dispersed drums are vertically located on the axis. Both pick-up drums are attached to the pick-up axis of the swing axle and are resting on the ground on both sides with sliding leads. The additional control of the pick-up drum is carried out by means of the rocker guides provided on both the side walls and in the middle. Due to the division of the rods with the teeth on the outer sides of the two halves of the drums, guide rail rails are necessary to control the transport teeth.
    However, this pick is characterized by
    melt heavy loads. A further improvement over the already known pick-up drums is the construction of divided beams with teeth. The beams with the teeth are separated along the entire length along the axis, and each half of the beams with the teeth is controlled from the end side of the pick-up drum. In the area of the separation of the beams with the teeth, there is a circular part on the drive shaft. Supporting areas are provided in the round frame for installing divided beams with teeth. To reduce the drive force and remove the peak force acting on the drive shaft, half of the teeth of one side of the take-up drum and half of the teeth of the other side of the drum are arranged symmetrically with a gap relative to each other. Four bearing sections are provided for four halves with teeth in the middle circular part. Thanks to this
    20, the arrangement is divided in half by the peak load acting on the drive shaft.
    However, despite the advantages achieved as compared with the well-known pick-up drums with a one-side guiding counter-rail or ice-running beams with teeth, the disadvantage of complex and incomplete copying of the soil is not eliminated. The entire drum, including the ramps, is rigidly attached to the carrier frame of the pick-up. Central Bier35
    so that the copying of the soil, the propagating shaft passes through both halves
    drum with teeth. Such an arrangement indicates that the soil can be copied by a drum with teeth only through the lifting device of the entire picker, which leads to large losses during the harvesting of agricultural crops.
    A pick-up with a soil copying drum with teeth is known (GDR Patent No. 143496, class A of D 89/00, August 27, 80.) 40 containing uncontrolled teeth, which, due to the seizure of the stems, winding them, which causes the machine to stop It has a very limited scope. The central shaft as a result of the transmission of large torque must be produced by the entire drum together with its slopes. Therefore, copying the soil is difficult and insufficient, which leads to large losses of the crop. In addition, the distance between the ends of the teeth and the cross transport screw all the time varies, which leads to the formation of layers of harvested culture in the gap to the cross transport screw, resulting in difficulties in transferring the mass of the culture and blockage occurs. The elastic sheathing for covering the clearance needed to swing across the full width of the gap eliminates completely the blockage. Drive movable receiving drums
    It is very complex and requires a lot of expenses, 45 bilny, while it can not be enough, as in this case we can talk only about a two-way drive.
    A pick-up drum is known for canted stalked and flap culture. Patent for industrial design
    precisely adapting flexibly to the unevenness of the soil, which again leads to large losses during harvesting.
    The purpose of the invention is the creation of such a pick for self-propelled harvesting machines No. 8000724. A pick-up drum with large pickup widths, which
    he would easily copy the soil, have the least losses during harvesting and would allow a continuous flow without disturbing the crop inside the picker.
    The main drive shaft and the guided beams with the teeth have guide rails located on the two side walls of the drum for unloading the control elements. This design, designed for a large working width, increases the service life of the pick-up drum, as the control elements do not test
    melt heavy loads. A further improvement over the already known pick-up drums is the construction of divided beams with teeth. The beams with the teeth are separated along the entire length along the axis, and each half of the beams with the teeth is controlled from the end side of the pick-up drum. In the area of the separation of the beams with the teeth, there is a circular part on the drive shaft. Supporting sections are provided in the round part for mounting divided beams with teeth. To reduce the drive force and remove the peak force acting on the drive shaft, half of the teeth of one side of the take-up drum and half of the teeth of the other side of the drum are arranged symmetrically with a gap relative to each other. Four bearing sections are provided for four halves with teeth in the middle circular part. Thanks to this
    In this arrangement, the peak load acting on the drive shaft is divided in half.
    However, despite the advantages achieved as compared with the well-known pick-up drums with a one-side guiding counter-rail or ice-running beams with teeth, the disadvantage of complex and incomplete copying of the soil is not eliminated. The entire drum, including the ramps, is rigidly attached to the carrier frame of the pick-up. The central drive shaft passes through both halves.
    precisely adapting flexibly to the unevenness of the soil, which again leads to large losses during harvesting.
    The purpose of the invention is to create such a bale for self-propelled sweepers with a large working width, which

    he would easily copy the soil, have the least losses during harvesting and would allow a continuous flow without disturbing the crop inside the picker.
    The invention is based on the task of creating such a pick-up for self-propelled large-width harvesters.
    NOI capture, the active mass of which when copying the soil would be minimal.
    The goal is achieved by the fact that the skid, moving from two sides on the main beam in the vertical plane, is connected to the drum guides through adjustable elements. The runner has vertically positioned tetrahedral posts and, in their vertical movement, moves along the plates attached from two frontal sides of the main beam and inwardly displaced between the guide rollers and the back side of the main beam. Inside the main beam, adjustable pipes are mounted on bearings directed to two outer sides, the inner ends of which are connected to runners by means of flip levers and connecting rods. The ends directed outwards are provided with lifting protrusions, which are connected to the drum guides through the lifting rods. Support plates are attached to the drum guides, on which guide cams are located for two-sided control of the rods with the teeth and a drum support with the teeth for the installation of the main drive shaft. The drum guides move with the drum with teeth entering the support plates between the side plates attached to the two front sides of the main beam in the roller guides and when the main beam is tilted in a tangential direction to the cross-sectional transport screw of the skew. This copying movement, transmitted from the runners through adjustable pipes to the guide drums, is facilitated by means of sets of springs suspended inside the guide drums, which remove the mass of the moving parts. The spring sets are closed with an overlap plate and the relief pressure is adjusted by means of set screws. The set screws are in the set plates attached to the top face of the main beam and screwed into the spring plate overlap plates. In order to ensure a good adaptation to the soil with a large working width, the drum with teeth has an average separation position. On the half of the drum with teeth on the drive side on the divided main drive shaft, a stop ring is attached to enter the ends at the point of separation of the rods with the teeth. A support surface is provided for the middle sub-liner. The latter is included in the support plate, which is attached to the four-sided stop of the middle runner. A four-sided stop attached to the skid moves in the same way as the drum guides between the roller guides tangentially to the transverse auger. Inside four square stop

    there is a set of springs, through which in the central part of the drum with teeth, the same relief effect is obtained as with the drum guides located on both sides. At the end of the half of the main drive shaft, on the drive side, there is a slide end of the shaft and a support section for a self-aligning bearing inlet. On the other half of the drum with the teeth in the place of separation there is a bowl-shaped case of the support, attached on the main drive shaft. On the outer face of this bearing housing are installed on the bearings of the place of separation of the rods with the teeth and in the cup-shaped internal cavity an end axle shaft is attached, which on the outside has a slot end, and inside it has free space for an eye bolt. Due to the movement of the drum with the teeth when copying the soil, which is also performed without loading the springs, the ease of travel is greatest. This ensures maximum adaptation to the soil and the lowest yield losses. The indicated direction of movement of the drum with the teeth guarantees a constant distance to the cross conveyor auger at any lifting height, as a result of which the blockage between the drum and the cross conveyor screw is eliminated. The invention can also be applied to a pick-up with a small width of the grip without divided head beams. Other solutions are possible when, for example, the movement of the runners is transmitted directly to the drum guides. This requires the location of the runners under the drum guides. In addition, the invention can also be applied to a pick-up with several times divided drums with teeth with a corresponding number of common support sections.
    FIG. 1 schematically shows the proposed pickup, top view; in fig. 2 - the same, side view (drive side); in fig. 3 - drive side, top view; in fig. 4 shows section A-A in FIG. one; in fig. 5 is a section BB in FIG. I; in fig. 6 is a sectional view BB in FIG. 1, in FIG. 7 - median bearing, top view (partial section).
    On the main frame 1 of the adapter transversely to the direction of motion Q, the main beam 2 passing through the entire working width is installed. Above the main beam 2 in the swivel sleeves 3 of the main frame 1 there is a movable transverse transport pin 4. Directly in front of the main beam 2 regardless of the main frame 1 there is a vertically moving drum 5 with teeth. The drum 5 in the entire field of movement is fenced with a gap by slopes 6, rigidly attached

    to the upper and lower edges of the main beam 2. The soil copying the swinging motion of the drum with the teeth 5, located in front of the main beam 2, is carried out through the skid 7, located on both frontal sides of the main beam 2 and displaced inwards. Vertical upward four-sided pillars 8 are attached to the skid m 7, which, in their vertical movement, pass from one side to the reverse side of the main beam 2 and from the other side between the guide rollers 10 located on the plate 9 of the main beam 2 10. Inside the main beam 2 s on both sides, adjustable pipes 11 are mounted on bearings directed to two outer sides. Levers 12 are attached to the ends of pipes 11 located above the runners 7, which by means of 2 connecting rods 1 passing through the main beam 2 3 are connected to the runners 7. At the outer ends of the pipes 11, levers 14 are attached. The latter are connected by means of 2 lifting rods 15 coming out of the main beam with drum guides 18 moving in roller guides 17 on side plates 16 located on both sides on the ends of the main beam 2. The drum guides 18, moving between the roller guides 17 obliquely upward tangentially to the outside diameter of the transverse transport screw 4, are attached to the supporting plates 19. On both inner sides of the supporting plates 1 9, guide cams 20 are arranged to control the strings 22 provided with the transporting teeth 21 and the support 23 of the main drive shaft 24 of the drum 5. In the swing motion directed through the skid 7, the adjustable pipes 11 and the lifting rods 15 are designed as tetrahedral racks the guide drum 18 did not lift the entire mass of the drum 5; inside the guide 18, the load-shed springs 25 are illuminated. The latter are closed by the overlap plates 26 and attached to the upper edge of the main beam 2 the new plates 27, protruding over the guides 18 running obliquely upwards, the set screws 28 are inserted into the plates 26 of the spring sets 25. Thus, on the setting plates 27, the set screws 28 adjust the sets of the springs 25 in accordance with the weight of the drum 5 so that through the runner 7 without The load on the main frame 1 can rotate the drum 5 inside the slopes 6 surrounding it. As a result, the moving weight is reduced so that the pressure of the runners 7 on the soil almost does not cause wear and the optimum light weight is established zhnoe sensing. Due to the large width

    the drum 5 is divided into two halves and the place of separation is supported by the middle skid 29, copying the soil. Half of the main drive shaft 24, on the drive side, has a mid-wheel bearing 30, a splined shaft end 31 serving as a linear expansion compensator, and ends with a mounted self-aligning bearing 32. The rods 22 are open at the disconnection point and enter
    in a stop ring 33 attached to the main drive shaft 24. On the other half of the drum 5, a bowl-shaped bearing housing 34 is attached to the main drive shaft 24. On the outer edge of the housing 34 are mounted on the rod bearings 22. To remove the load from the rod drive 22 in this half drum 5 are offset in a known manner by 45 °. In the more often internal cavity of the housing 34, an end axle 35 of the shaft is attached. End spigot
