Technical Field

[0001] The invention relates to the technical field of threshers, in particular to a red kidney bean thresher. Background Art

[0002] A thresher is a machine that threshes crops, usually corn, kidney beans, wheat, rice, etc. Its main function is to separate the grains from the crops and remove impurities such as the husks and branches of the ears or pods.

[0003] When using a thresher to thresh crops, usually, the operator first puts the crops into the threshing device, and the ears or pods of the crops are crushed, rubbed and struck by the threshing device, so that the crop grains are separated from the ears or pods, thereby completing the threshing of the crops.

[0004] Although the current thresher can improve the processing efficiency of crops and reduce the labor intensity of operators, in actual use, the current thresher still has shortcomings, specifically: when threshing red kidney beans, since the vines of red kidney beans are usually more and longer, after the red kidney beans are put into the threshing device, the longer vines are easy to be entangled on the threshing roller, on the one hand, the resistance to the rotation of the threshing roller is increased, on the other hand, after the vines are entangled on the threshing roller, it is easy to cause the vines and the threshing roller to rotate synchronously, so that the threshing roller is difficult to break the pods on the vines entangled on the threshing roller, which increases the probability of kidney beans remaining in the pods on the vines.

[0005] Therefore, how to reduce the probability of red kidney bean vines being entangled on the threshing roller is a problem that urgently needs to be solved. Summary of the invention

[0006] The purpose of the present invention is to provide a red kidney bean thresher to reduce the probability of the red kidney bean vines being entangled on the threshing roller in view of the disadvantage that the vines of the red kidney bean are easily entangled on the threshing roller.

[0016] As a preferred technical solution of the present application, a plurality of cross bars are arranged on the turntable, and the plurality of cross bars are evenly distributed in an area near the edge of the turntable.

[0017] Compared with the prior art, the present invention has the following beneficial effects: 1. In the scheme of the present application, by arranging a cutting blade on the threshing rod, during the process of threshing the kidney beans placed in the threshing bin, the driving assembly drives the threshing rod to move, so that the cutting blade on the threshing rod moves together with the threshing rod, and then the cutting blade cuts the kidney bean vines of the kidney beans, so as to cut a longer kidney bean vine into several shorter kidney bean vines, thereby reducing the length of a single kidney bean vine, and further reducing the probability of the kidney bean vine being entangled on the threshing roller assembly, so as to make it more convenient for the threshing rod to strike the kidney beans, thereby improving the efficiency of obtaining kidney bean grains; 2. Furthermore, by providing a rotating disk and a cross bar, and rotatably connecting a plurality of threshing bars to the cross bar, the degree of the threshing bars hitting the kidney beans can be further improved, thereby improving the threshing efficiency. Moreover, after the portion of the threshing bar that is connected to the cross bar is staggered from the center of gravity of the threshing bar, when the rotating disk rotates at a high speed, the threshing bar can, under the action of centrifugal force, make the extension line of the line connecting the center of gravity of the threshing bar and the portion of the threshing bar that is connected to the cross bar pass through the rotating axis of the rotating disk; when the rotating disk rotates at a low speed, the center of gravity of the threshing bar and the line connecting the portion of the threshing bar that is connected to the cross bar can be staggered. In the vertical direction, when the center of gravity of the threshing rod is at the central axis of the threshing rod, or when the center of gravity of the threshing rod is near the central axis of the threshing rod, the threshing rod can be in a vertical state during the low-speed movement of the turntable; in this way, when kidney beans are put into the threshing bin, when the threshing rod is in a stationary state or a low-speed rotating state, the threshing rod is in a vertical state, so that there is no threshing rod in the upper area of ​​the threshing bin, thereby providing more accommodating space for the put kidney beans, improving the convenience of putting the kidney beans into the threshing bin, and when the threshing rod and the turntable are in a high-speed rotating state, it is more convenient for the threshing rod to hit the kidney beans; 3. Furthermore, by setting a first rod body, the first rod body abuts against the cutting blade. When the first rod body slides along the length direction of the first slide groove, the position of the cutting blade abutting against the first rod body changes, so that the cutting blade moves relative to the blade matching groove, and then the cutting blade extends from the blade matching groove or retracts into the blade matching groove. Then, when the turntable is in a low-speed rotation state, the threshing rod is in an initial state, and its cutting blade extends out of the blade matching groove. With the rotation of the threshing rod, the cutting blade cuts the kidney bean vines under low-speed movement, thereby preventing the high-speed moving cutting blade from causing damage to the kidney bean grains while cutting the kidney bean vines. The first spring is pressed against the sprocket when the threshing bar is in a state of high-speed movement, and the first spring is pressed against the sprocket when the threshing bar is in a state of high-speed movement, so that the threshing bar is pressed against the sprocket when the threshing bar is in a state of high-speed movement, so that the threshing bar is pressed against the sprocket when the threshing bar is in a state of high-speed movement, so that the threshing bar is pressed against the sprocket when the threshing bar is in a state of high-speed movement, so that the threshing bar is pressed against the sprocket when the threshing bar is in a state of high-speed movement, so that the threshing bar is pressed against the sprocket when the threshing bar is in a state of high-speed movement, so that the threshing efficiency of the threshing bar and the integrity of the threshing bar are improved. 4. Furthermore, by setting a second rod body and a gear, the first rack on the first rod body is meshed with the gear, the second rack on the second rod body is meshed with the gear, and the meshing portion of the first rack with the gear and the meshing portion of the second rack with the gear are on opposite sides of the gear, so that the movement direction of the first rod body relative to the threshing rod body is opposite to the movement direction of the second rod body relative to the threshing rod body; when the threshing rod is in an initial state, the threshing rod is in a maximum length state, in which the turntable can be in a low-speed rotation state, so that when the threshing rod moves to the lowest point, the threshing rod can be at the shortest distance from the inner wall of the threshing bin, thereby making it easier for the threshing rod to contact the kidney beans to stir the kidney beans, thereby greatly improving the degree of stirring of the kidney beans in the threshing bin on the basis of reducing the risk of kidney bean grains being broken, and at the same time making it easier for the cutting blade on the threshing rod to cut the kidney bean vines; Furthermore, as the rotation speed of the turntable continues to increase, under the action of centrifugal force, the first rod body can slide relative to the first slide groove in the direction away from the central axis of the turntable, and driven by the gear, the second rod body can slide relative to the second slide groove in the direction close to the rotation axis of the turntable, so that the length of the threshing rod gradually shortens. In this way, the distance between the bottom end of the threshing rod and the inner wall of the threshing bin is increased. During the threshing process, a certain space is provided for the movement of the kidney bean grains, which can reduce the probability of the threshing rod hitting the threshed kidney bean grains, thereby reducing the risk of the kidney bean grains being broken.

[0024] Embodiment 1: This embodiment provides a red kidney bean thresher, see Figure 1-Figure 9 As shown, it includes a threshing bin 1 and a threshing roller assembly 2, the threshing bin 1 is used to accommodate kidney beans, the threshing roller assembly 2 includes a threshing rod 3 and a driving assembly 4, the threshing rod 3 is located in the threshing bin 1, the driving assembly 4 is used to drive the threshing rod 3 to move relative to the threshing bin 1, so that the threshing rod 3 strikes the kidney beans put into the threshing bin 1, so as to separate the kidney bean grains from the pods, and the threshing rod 3 is provided with a cutting blade 5, and the cutting blade 5 is used to cut the kidney bean vines.

[0025] In the present application, by arranging a cutting blade 5 on the threshing rod 3, during the process of threshing the kidney beans placed in the threshing bin 1, the driving assembly 4 drives the threshing rod 3 to move, so that the cutting blade 5 on the threshing rod 3 moves together with the threshing rod 3, and then the cutting blade 5 cuts the kidney bean vines of the kidney beans, so as to cut the longer kidney bean vines into several shorter kidney bean vines, thereby reducing the length of a single kidney bean vine, and further reducing the probability of the kidney bean vines being entangled in the threshing roller assembly 2, which is more conducive to the threshing rod 3 to strike the kidney beans, thereby improving the efficiency of obtaining kidney bean grains.

[0026] As a preferred embodiment, on the basis of the above-mentioned manner, further, the driving assembly 4 includes a turntable 6 and a cross bar 7, the cross bar 7 is arranged on the turntable 6, the length direction of the cross bar 7 is in the same direction as the length direction of the threshing bin 1, the end of the threshing rod 3 is rotatably connected to the cross bar 7, the threshing rod 3 is a plurality of threshing rods 3, and the plurality of threshing rods 3 are arranged along the length direction of the cross bar 7, the turntable 6 is adapted to be equipped with a motor device 8, and the motor device 8 is used to drive the turntable 6 to rotate, so that the cross bar 7 and the turntable 6 rotate synchronously; The portion of the threshing bar 3 that is connected to the cross bar 7 is offset from the center of gravity of the threshing bar 3 .

[0027] Furthermore, by providing a turntable 6 and a cross bar 7, and rotatably connecting a plurality of threshing rods 3 to the cross bar 7, the degree of striking of the kidney beans by the threshing rods 3 is further improved, thereby improving the threshing efficiency. Moreover, after the portion of the threshing rod 3 that is connected to the cross bar 7 is staggered from the center of gravity of the threshing rod 3, when the turntable 6 rotates at a high speed, the threshing rod 3, under the action of the centrifugal force, can make the extension line of the line connecting the center of gravity of the threshing rod 3 and the portion of the threshing rod 3 that is connected to the cross bar 7 pass through the rotation axis of the turntable 6; when the turntable 6 rotates at a low speed, the extension line of the line connecting the center of gravity of the threshing rod 3 and the portion of the threshing rod 3 that is connected to the cross bar 7 can pass through the rotation axis of the turntable 6. The line is in a vertical direction, and when the center of gravity of the threshing rod 3 is at the central axis of the threshing rod 3, or when the center of gravity of the threshing rod 3 is near the central axis of the threshing rod 3, the threshing rod 3 can be in a vertical state during the low-speed movement with the turntable 6; in this way, when kidney beans are put into the threshing bin 1, when the threshing rod 3 is in a stationary state or a low-speed rotating state, the threshing rod 3 is in a vertical state, so that there is no threshing rod 3 in the upper area of ​​the threshing bin 1, thereby providing more accommodating space for the put kidney beans, improving the convenience of putting the kidney beans into the threshing bin 1, and when the threshing rod 3 and the turntable 6 are in a high-speed rotating state, it is more conducive to the threshing rod 3 to hit the kidney beans.

[0028] Specifically, the output shaft of the motor on the motor device 8 is connected to the turntable 6, thereby driving the turntable 6 to rotate. The specific structure is prior art, so it will not be described here.

[0029] As a preferred embodiment, on the basis of the above-mentioned manner, further, the threshing rod 3 includes a threshing rod body 9 and a first rod body 10, the threshing rod body 9 is provided with a blade matching groove 11 and a first slide groove 12, the cutting blade 5 is matched with the blade matching groove 11, and a first spring 13 is connected between the cutting blade 5 and the threshing rod body 9, and the first spring 13 has elasticity; The first rod body 10 is matched with the first slide groove 12, and a stop block 14 is arranged on the threshing rod body 9. A second spring 15 is connected between the stop block 14 and the first rod body 10. The second spring 15 is elastic. The length direction of the first slide groove 12 is in the same direction as the length direction of the threshing rod body 9. The first rod body 10 can slide along the length direction of the first slide groove 12. The first rod body 10 abuts against the cutting blade 5; The threshing rod 3 has an initial state. When the threshing rod 3 is in the initial state, the cutting blade 5 extends out of the blade matching groove 11, and the first spring 13 is in a stretched state. When the motor device 8 drives the turntable 6 to rotate, under the action of centrifugal force, the first rod body 10 can slide relative to the first slide groove 12 in the direction away from the rotation axis of the turntable 6. During the sliding of the first rod body 10 relative to the first slide groove 12 in the direction away from the rotation axis of the turntable 6, the position of the cutting blade 5 that is against the first rod body 10 changes, the deformation of the first spring 13 gradually decreases, the cutting blade 5 gradually retracts into the blade matching groove 11, and the deformation of the second spring 15 gradually increases.

[0030] Furthermore, by setting the first rod body 10, the first rod body 10 abuts against the cutting blade 5. When the first rod body 10 slides along the length direction of the first slide groove 12, the position of the cutting blade 5 abutting against the first rod body 10 changes, so that the cutting blade 5 moves relative to the blade matching groove 11, and then the cutting blade 5 extends from the blade matching groove 11 or retracts into the blade matching groove 11. Then, when the turntable 6 is in a low-speed rotation state, the threshing rod 3 is in an initial state, and its cutting blade 5 extends out of the blade matching groove 11. With the rotation of the threshing rod 3, the cutting blade 5 cuts the kidney bean vines under low-speed movement, thereby preventing the cutting blade 5 from moving at high speed while cutting the kidney bean vines. The kidney bean grains are damaged, thereby reducing the probability of the kidney bean grains being cut by the cutting blade 5; when the turntable 6 is in a high-speed rotating state, under the action of centrifugal force, the first rod body 10 can slide relative to the first slide groove 12 in a direction away from the central axis of the turntable 6, so that the deformation of the first spring 13 is reduced. Under the action of the gradual recovery of the deformation of the first spring 13, the cutting blade 5 is gradually retracted into the blade matching groove 11, so that when the threshing rod 3 is in a high-speed motion state, the high-speed moving cutting blade 5 is prevented from cutting the kidney beans, further reducing the probability of the kidney beans being cut by the cutting blade 5, and at the same time, it is conducive to the high-speed moving threshing rod 3 to hit the kidney beans, thereby improving the kidney bean threshing efficiency and the integrity of the kidney bean grains.

[0031] As a preferred embodiment, on the basis of the above method, further, a first stop portion 16 is provided in the blade mating groove 11, and the first stop portion 16 is used to resist the cutting blade 5, and the first stop portion 16 is used to limit the elongation of the cutting blade 5 when it extends out of the blade mating groove 11, so that the cutting blade 5 is always in a state of mating with the blade mating groove 11.

[0032] Furthermore, by providing the first abutment portion 16 , the first abutment portion 16 is used to abut against the cutting blade 5 to limit the elongation of the cutting blade 5 when it extends out of the matching groove, thereby improving the stability of the matching between the cutting blade 5 and the blade matching groove 11 .

[0033] Embodiment 2: Based on the technical solution of embodiment 1, further, see Figure 1-Figure 9 As shown, the position of the stop block 14 along the length direction of the threshing rod body 9 is adjustable, so that when the threshing rod 3 is in the initial state, the initial deformation amount of the second spring 15 is adjustable.

[0034] Furthermore, the position of the stop block 14 is adjustable along the length direction of the threshing rod body 9. Thus, by adjusting the position of the stop block 14, the initial deformation of the second spring 15 can be adjusted when the threshing rod 3 is in the initial state. Thus, when the speed of rotation of the turntable 6 driven by the motor device 8 is constant, the initial deformation of the second spring 15 is different, which will cause different displacements of the first rod body 10 relative to the threshing rod body 9, so that the position of the cutting blade 5 relative to the blade matching groove 11 is different, thereby being able to adjust the rotation speed of the turntable 6 required to fully retract the cutting blade 5 to the blade matching groove 11, which is more conducive to the operator's control of the extension or retraction of the cutting blade 5.

[0035] As a preferred embodiment, on the basis of the above-mentioned manner, further, the block 14 includes a block part 17 and a block part 18, the block part 17 and the block part 18 are rotatably connected, the rotation axis of the block part 17 and the block part 18 is in the same direction as the length direction of the threshing rod body 9, the block part 17 is connected to the second spring 15, and the block part 18 is threadedly connected to the threshing rod body 9; When the second stopper portion 18 rotates relative to the threshing rod body 9 , the stopper 14 moves relative to the threshing rod body 9 along the length direction of the threshing rod body 9 .

[0036] Furthermore, by providing the first stop block 17 and the second stop block 18, when the second stop block 18 is rotated relative to the threshing rod body 9, the second stop block 18 drives the first stop block 17 to move along the length direction of the threshing rod body 9, so that the stop block 14 moves relative to the threshing rod body 9 along the length direction of the threshing rod 3, thereby improving the convenience of adjusting the position of the stop block 14.

[0037] Embodiment 3: Based on the technical solution of Embodiment 2, further, see Figure 1-Figure 9 As shown, the threshing rod 3 also includes a second rod body 19, and the threshing rod body 9 is also provided with a second slide groove 20 and a gear 21, the second rod body 19 cooperates with the second slide groove 20, the length direction of the second slide groove 20 is in the same direction as the length direction of the threshing rod body 9, the first rod body 10 is provided with a first rack 22, the second rod body 19 is provided with a second rack 23, the first rack 22 is meshed with the gear 21, the second rack 23 is meshed with the gear 21, and the meshing part of the first rack 22 and the gear 21 and the meshing part of the second rack 23 and the gear 21 are on the opposite sides of each other with respect to the gear 21; When the threshing bar 3 is in the initial state, the threshing bar 3 is in the maximum length state; Under the action of centrifugal force, when the first rod body 10 slides relative to the first slide groove 12 in the direction away from the rotation axis of the turntable 6, the first rack 22 drives the gear 21 to move, and the gear 21 drives the second rack 23 to rotate, so that the second rod body 19 slides relative to the second slide groove 20 in the direction close to the rotation axis of the turntable 6, so that the length of the threshing rod 3 becomes shorter.

[0038] Furthermore, by providing the second rod 19 and the gear 21, the first rack 22 on the first rod 10 is meshed with the gear 21, the second rack 23 on the second rod 19 is meshed with the gear 21, and the meshing portion of the first rack 22 and the gear 21 and the meshing portion of the second rack 23 and the gear 21 are on opposite sides of each other with respect to the gear 21, so that the movement direction of the first rod 10 relative to the threshing rod body 9 is opposite to the movement direction of the second rod 19 relative to the threshing rod body 9; When the threshing rod 3 is in the initial state, the threshing rod 3 is in the maximum length state. In this state, the turntable 6 can be in a low-speed rotation state, so that when the threshing rod 3 moves to the lowest point, the distance between the threshing rod 3 and the inner wall of the threshing bin 1 can be the shortest, thereby making it easier for the threshing rod 3 to contact the kidney beans to stir the kidney beans, thereby greatly improving the degree of stirring of the kidney beans in the threshing bin 1 on the basis of reducing the risk of kidney bean grains being broken, and at the same time making it easier for the cutting blade 5 on the threshing rod 3 to cut the kidney bean vines; Furthermore, as the rotation speed of the turntable 6 continues to increase, under the action of centrifugal force, the first rod body 10 can slide relative to the first slide groove 12 in the direction away from the central axis of the turntable 6, and driven by the gear 21, the second rod body 19 slides relative to the second slide groove 20 in the direction close to the rotation axis of the turntable 6, thereby gradually shortening the length of the threshing rod 3. In this way, the distance between the bottom end of the threshing rod 3 and the inner wall of the threshing bin 1 is increased. During the threshing process, a certain space is provided for the movement of the kidney bean grains, which can reduce the probability of the threshing rod 3 hitting the threshed kidney bean grains, thereby reducing the risk of the kidney bean grains being broken.

[0039] As a preferred embodiment, on the basis of the above method, further, the second rod body 19 includes a second main rod body 24 and a second auxiliary rod body 25, the second main rod body 24 is connected to the second auxiliary rod body 25, and the position of the second auxiliary rod body 25 relative to the second main rod body 24 is adjustable. By adjusting the position of the second auxiliary rod body 25 relative to the second main rod body 24, the length of the second rod body 19 can be adjusted.

[0040] Furthermore, by setting a second main rod body 24 and a second auxiliary rod body 25, the length of the second rod body 19 can be adjusted by adjusting the position of the second auxiliary rod body 25 relative to the second main rod body 24, so as to facilitate adjusting the distance between the bottom end of the threshing rod 3 and the inner wall of the threshing bin 1 when the threshing rod 3 is in the initial state, thereby improving the convenience of adjusting the distance. At the same time, the second main rod body 24 and the second auxiliary rod body 25 are connected by threads, and the specific connection method is the existing technology, so it is not repeated here.

[0041] As a preferred embodiment, based on the above method, further, when the threshing rod 3 is in the initial state, the minimum distance between the inner wall of the threshing bin 1 and the end of the threshing rod 3 away from the rotation axis of the turntable 6 is d, 0<distance d<3cm.

[0042] Furthermore, when the threshing rod 3 is in the initial state, 0 is set to be less than the distance d and less than 3 cm. During the low-speed rotation of the turntable 6, the threshing rod 3 contacts the kidney bean grains on the inner wall of the threshing bin 1, so as to promote the movement of the kidney bean grains in the threshing bin 1, thereby facilitating the kidney bean grains in the threshing bin 1 to fall through the filter screen on the inner wall of the threshing bin 1 into the kidney bean grain collecting device, thereby improving the convenience of collecting the kidney bean grains.

[0043] As a preferred embodiment, on the basis of the above-mentioned manner, further, a plurality of cross bars 7 are provided on the turntable 6 , and the plurality of cross bars 7 are evenly distributed on the turntable 6 in an area close to the edge of the turntable 6 .

[0044] Furthermore, by setting a plurality of cross bars 7, the threshing bars 3 in the threshing bin 1 are more widely distributed, thereby further improving the efficiency of kidney bean threshing. At the same time, the plurality of cross bars 7 are evenly distributed on the turntable 6 in the area close to the edge of the turntable 6, so as to increase the centrifugal force on the threshing bars 3 when the turntable 6 rotates, which is more conducive to the threshing bar 3 under the action of the centrifugal force, so that the center of gravity of the threshing bar 3 and the extension line of the line connecting the part of the threshing bar 3 for connecting with the cross bars 7 pass through the rotation axis of the turntable 6.

[0045] The above embodiments are only used to illustrate the present invention and are not intended to limit the technical solutions described in the present invention. Although the present invention has been described in detail with reference to the above embodiments, the present invention is not limited to the above specific implementation methods. Therefore, any modification or equivalent replacement of the present invention; and all technical solutions and improvements thereof that do not depart from the spirit and scope of the invention are included in the scope of the claims of the present invention.
