[0017] The beneficial effects of this invention are as follows: 1. The present invention provides a kidney bean threshing and spreading machine that facilitates threshing. Utilizing a self-draining threshing mechanism, it automatically threshes kidney beans, allowing for concentrated collection of seeds for subsequent processing. Simultaneously, the machine clears multiple sets of through-holes, preventing blockage by pods or other impurities and ensuring effective threshing.

[0018] 2. The present invention provides a bean threshing and spreading machine that facilitates threshing. Based on the height of the bean stalks, the threaded rod is manually rotated to raise and lower the lifting plate, adjusting the height of multiple blades. Then, a motor is started, driving a sprocket on one side to rotate. Under the action of the chain, multiple blades rotate simultaneously. As the machine moves forward, the bean stalks are cut, thus preparing for the subsequent threshing process and improving harvesting efficiency.
[0019] 3. The present invention provides a kidney bean lifting and spreading machine for easy threshing. Utilizing an inner wall scraping component, when kidney bean seeds adhere to the inner wall of the threshing cylinder, the inner wall of the threshing cylinder is driven to move relative to the end of the collecting plate. The collecting plate scrapes away the kidney bean seeds adhering to the inner wall of the threshing cylinder. Subsequently, multiple push blocks push the kidney bean seeds to the through-hole, allowing them to fall smoothly through the through-hole. This avoids the situation where some kidney bean seeds are difficult to collect due to adhering to the inner wall of the threshing cylinder. Attached Figure Description

Electric push rod 32 is fixedly connected to the middle of the upper end face of the mounting plate 26, and the piston end of electric push rod 32 is fixedly connected to the middle of scraper 23. Specifically, kidney beans are a type of nutritious legume. During the planting process of kidney beans, the pulling and spreading machine can be used to pull the kidney beans out of the soil and neatly spread them on the ground, making it convenient for farmers to carry out subsequent processing and storage. Since the edible or industrial value of kidney beans is mainly reflected in their seeds, the existing kidney bean pulling and spreading machine is inconvenient to separate the pods and seeds after the kidney beans are harvested, which is not conducive to further processing of the kidney bean seeds. Therefore, in this embodiment, the device is pulled by a tractor, and the root-lifting device 12 is used to lift the roots of the seedlings. After the kidney beans are lifted, they are neatly arranged in the collection area at the rear of the machine. Then, the cylinder cover 16 is opened, and the harvested kidney beans are placed into the threshing cylinder 14. The motor 33 is started to drive the convex rod 43 to rotate. When the convex rod 43 rotates, the grooved cylinder 42 and the bevel gear 31 rotate synchronously, which makes the bevel gear 20 and the threshing cylinder 14 rotate simultaneously. Furthermore, with the cooperation of the bevel gear 44 and the bevel gear 121, the crank 22 rotates continuously, which makes the rectangular block 36 perform circular motion, causing the chute to slide. The rod 35 moves up and down reciprocally. When the sliding rod 35 moves up and down reciprocally, the L-shaped plate 39 moves up and down reciprocally. The grooved cylinder 42 slides on the protruding rod 43, and the sleeve 38 slides on the sliding rod 37, causing the threshing cylinder 14 to vibrate up and down. This allows the threshing cylinder 14 to perform a combined rotation and up-and-down vibration motion. When the threshing cylinder vibrates, the kidney beans vibrate, and the kidney bean seeds fall out of the pods. The kidney bean seeds will fall from the through hole 15 into the collection box 20, while the pods and other impurities will remain inside the threshing cylinder 14. This allows for automatic threshing of the kidney beans, enabling the kidney bean seeds to be collected in a concentrated manner, which facilitates subsequent processing of the kidney bean seeds. During the threshing process, pods or impurities may clog the through holes 15, affecting the screening effect. Therefore, with the continuous rotation of the threshing cylinder 14, when any set of through holes 15 aligns with the unblocking column 27, the electric actuator 24 is activated and moves the mounting plate 26, causing the mounting plate 26 to move the unblocking column 27 closer to the through hole 15. Simultaneously, since the threshing cylinder 14 is still rotating, the rotating arm 19 can be rotated under the action of the motor 18, causing the unblocking column 27 to rotate with the threshing cylinder 14, ensuring that the unblocking column 27 is always aligned with one set of through holes 15. 5. Furthermore, when the unblocking column 27 passes through the through hole 15, it can push the pods or impurities blocking the through hole 15 back into the threshing cylinder 14, and then drive the unblocking column 27 out of the through hole 15 again. At this time, the motor 18 makes the unblocking column 27 return to the initial position. At this time, the unblocking column 27 is also aligned with the next set of through holes 15. Then, the above operation is repeated to unblock the next set of through holes 15, so that multiple sets of through holes 15 can be unblocked, avoiding the situation where the through holes 15 are blocked by pods or other impurities, and ensuring the threshing effect. Because the unclogging column 27 comes into contact with bean pods or other impurities when passing through the through hole 15, bean pods or impurities may adhere to its surface or end. When the unclogging column 27 passes through another through hole 15, the impurities on its surface may re-adhere into the through hole 15, increasing the risk of re-clogging. Therefore, during the unclogging process of the unclogging column 27 after completing one unclogging operation and returning to its initial position, the electric actuator 20 can be activated to move the scraper ring assembly 28, and the slide rod 39 can slide on the mounting plate 26, causing the scraper ring assembly 28 to move towards the end of the unclogging column 27 until the scraper ring assembly 28 threshes the pods from the unclogging column 27, thus removing the impurities from its surface. While the scraper is being scraped off, the scraper 23 can slide downwards on the slide bar 31 under the action of the electric push rod 32. When the bottom edge of the scraper 23 contacts the end surface of the unblocking column 27, the impurities adhering to the surface of the unblocking column 27 can be pushed off. Thus, the unblocking column 27 can be self-cleaned. This can prevent impurities from adhering to the unblocking holes 15 again when unblocking the next set of holes 15, making the unblocking column 27 more effective for recycling. Furthermore, since the unblocking column 27 is in a state away from the threshing cylinder 14 when it completes one unblocking and returns to its initial position, impurities will not fall into the collection box 20 and mix with the kidney bean seeds when the unblocking column 27 performs self-cleaning. By utilizing a self-dredging threshing mechanism, kidney beans can be automatically threshed, allowing for concentrated collection of seeds and facilitating subsequent processing. Simultaneously, the threshing process unblocks multiple sets of through-holes 15, preventing blockage by pods or other impurities and ensuring effective threshing. Furthermore, after each unblocking operation, the scraper ring group 28 and scraper 23 remove impurities from the surface of the unblocking column 27, achieving self-cleaning. This prevents impurities from re-adhering to the through-holes 15 when unblocking the next set, resulting in better reusability of the unblocking column 27.
[0026] In this embodiment, as Figure 1 As shown, multiple rotating shafts 4 are slidably connected to the front side of the base 13, and blades 3 are fixedly connected to the lower end of the rotating shafts 4. A lifting plate 8 is rotatably mounted on the rotating shafts 4. Both sides of the rotating shaft 4 are fitted with sprocket 11. The middle side of the rotating shaft 4 is fitted with sprocket 10. Both sprocket 10 and sprocket 11 are meshed with chain 9. Motor 7 is fixedly connected to one side of the upper surface of the lifting plate 8. The output end of motor 7 is fixedly connected to the left sprocket 11. Threaded rod 5 is threadedly connected to the left end of the lifting plate 8. The lower end of threaded rod 5 is rotatably set on one side of the upper surface of the base 13. Sliding rod 6 is slidably connected to the right end of the lifting plate 8. The lower end of sliding rod 6 is fixedly connected to one side of the upper surface of the base 13. Specifically, based on the height of the bean vines, the threaded rod 5 is manually rotated to raise and lower the lifting plate 8, adjusting the height of multiple blades 3. Then, the motor 7 is started to drive the sprocket 11 on one side to rotate. Under the action of the chain 9, multiple blades 3 rotate simultaneously. When the vehicle body 1 moves, the bean vines can be cut. By cutting the bean vines, preparations can be made for the subsequent pulling process, improving the harvesting effect.
[0027] In this embodiment, as Figures 9-13 As shown, it also includes an inner wall scraping component; The inner wall scraping assembly includes a gear 2 51 rotatably mounted on one side of the inner wall of the threshing cylinder 14. A housing 49 is fixedly connected to one side of the gear 2 51. Two guide rods 48 are slidably connected to one side of the housing 49. A gathering plate 52 is fixedly connected to one end of each guide rod 48. Multiple push blocks 45 are slidably connected to the groove of the gathering plate 52. A motor 46 is fixedly connected to one side of the outer wall of the threshing cylinder 14. A gear 1 50 is fixedly connected to the output end of the motor 46. The gear 1 50 is rotatably mounted on the threshing cylinder 14 and meshes with the gear 2 51. An electric push rod 47 is fixedly connected to one side of the inner cavity of the housing 49. The piston end of the electric push rod 47 is fixedly connected to one side of the gathering plate 52. A lead screw 53 is rotatably mounted at both ends of the groove of the gathering plate 52. Multiple threads are intermittently provided on the lead screw 53, and the lead screw 53 is threadedly connected to multiple push blocks 45. A motor 54 is fixedly connected to one end of the groove of the gathering plate 52. The output end of the motor 54 is fixedly connected to one end of the lead screw 53.
[0028] Specifically, in the above embodiments, although the threshing cylinder 14 can be used for threshing, some kidney bean seeds may stick to the inner wall of the threshing cylinder 14, which will prevent the kidney bean seeds from being discharged normally from the through hole 15, thus affecting the collection of kidney bean seeds.
[0029] Therefore, in order to solve the above problems, the working principle of this embodiment is as follows: When kidney bean seeds adhere to the inner wall of the threshing cylinder 14, the motor 46 drives the gear 50 to rotate, which in turn causes the gear 51 to rotate, so that the end of the gathering plate 52 faces downward and is in contact with the inner wall of the threshing cylinder 14. Then, the threshing cylinder 14 and the gear 51 are driven to rotate simultaneously in opposite directions, so that the gathering plate 52 remains in its original position. When the inner wall of the threshing cylinder 14 moves relative to the end of the gathering plate 52, the gathering plate 52 will scrape the kidney bean seeds adhering to the inner wall of the threshing cylinder 14, so that the kidney bean seeds are gathered at the gathering plate 52, and the threshing cylinder 14 stops moving after rotating one revolution. At this time, since a row of through holes 15 is located at the bottom of the gathering plate 52, the kidney bean seeds gathered at the gathering plate 52 will fall out through the through holes 15. Furthermore, since there is a gap between adjacent through holes 15, if the kidney bean seeds stay within the gap between two through holes 15, the kidney bean seeds will not fall out. Therefore, the motor 54 can drive the lead screw 53 to rotate, causing multiple push blocks 45 to move simultaneously. In the initial state, two adjacent push blocks 45 are in contact with each other. When two adjacent push blocks 45 move away from each other, they will push the kidney bean seeds to the through holes 15, so that the kidney bean seeds can fall out smoothly through the through holes 15, thereby avoiding the situation where some kidney bean seeds are difficult to collect due to adhering to the inner wall of the threshing cylinder 14.
[0030] Working principle: Based on the height of the bean vines, manually rotate the threaded rod 5 to raise and lower the lifting plate 8, adjusting the height of multiple blades 3. Then, start the motor 7 to drive the sprocket 11 on one side to rotate. Under the action of the chain 9, multiple blades 3 rotate simultaneously. The device is pulled by a tractor. When the vehicle 1 moves, the bean vines can be cut. By cutting the bean vines, the subsequent pulling process can be prepared, improving the harvesting effect. Use the root remover 12 to remove the roots of the seedlings. After the beans are removed, they will be neatly arranged in the collection area at the rear of the machine. Then, open the cylinder cover 16 and put the harvested beans into the threshing cylinder 14. Start the motor 33 to drive the convex rod 43 to rotate. When the convex rod 43 rotates, the grooved cylinder 42 and the bevel gear 41 rotate synchronously, thus enabling the bevel gear to rotate. The threshing cylinder 14 and the bevel gear 44 rotate simultaneously. With the cooperation of the bevel gear 44 and the bevel gear 21, the crank 22 rotates continuously, which makes the rectangular block 36 move in a circular motion and the sliding rod 35 move up and down. When the sliding rod 35 moves up and down, the L-shaped plate 39 moves up and down. The grooved cylinder 42 slides on the protruding rod 43 and the sleeve 38 slides on the sliding rod 37, which makes the threshing cylinder 14 vibrate up and down. This makes the threshing cylinder 14 perform a combined motion of rotation and up and down vibration. When the threshing cylinder vibrates, the kidney beans vibrate, and the kidney bean seeds fall out of the pods. The kidney bean seeds will fall from the through hole 15 into the collection box 20, while the pods and other impurities will remain inside the threshing cylinder 14. This allows for automatic threshing of the kidney beans, enabling the kidney bean seeds to be collected in a concentrated manner, which facilitates subsequent processing of the kidney bean seeds. During the threshing process, pods or impurities may clog the through holes 15, affecting the screening effect. Therefore, with the continuous rotation of the threshing cylinder 14, when any set of through holes 15 aligns with the unblocking column 27, the electric actuator 24 is activated and drives the mounting plate 26 to move. This causes the mounting plate 26 to move the unblocking column 27, bringing it closer to the through hole 15. Simultaneously, since the threshing cylinder 14 is still rotating, the rotating arm 19 can be rotated under the action of the motor 18, causing the unblocking column 27 to rotate with the threshing cylinder 14. This ensures that the unblocking column 27 is always aligned with one set of through holes 15. Furthermore, when the unblocking column 27 passes through the through hole 15... At 5 o'clock, the pods or impurities blocking the through-hole 15 can be pushed to fall back into the threshing cylinder 14, and then the unblocking column 27 is driven to extend out of the through-hole 15 again. At this time, the motor 18 returns the unblocking column 27 to its initial position, and the unblocking column 27 is now aligned with the next set of through-holes 15. The above operation is repeated to unblock the next set of through-holes 15, thus unblocking multiple sets of through-holes 15 and avoiding blockage by pods or other impurities, ensuring the threshing effect. Since the unblocking column 27 comes into contact with pods or other impurities when passing through the through-hole 15, it may cause... Currently, the surface or end of the unblocking column 27 is covered with bean pods or impurities. When the unblocking column 27 passes through the other through holes 15 again, the impurities on the surface of the unblocking column 27 may re-adhere into the through holes 15, increasing the risk of re-clogging of the through holes 15. Therefore, during the process of the unblocking column 27 completing one unblocking operation and returning to its initial position, the electric actuator 30 can be activated to move the scraper ring assembly 28, and the slide rod 39 slides on the mounting plate 26, causing the scraper ring assembly 28 to move towards the end of the unblocking column 27 until the scraper ring assembly 28 detaches the pods from the unblocking column 27, thus scraping off the impurities on the surface of the unblocking column 27. At the same time, the electric actuator 32 can be activated... Under the action, the scraper 23 slides downward on the slide bar 31. When the bottom edge of the scraper 23 contacts the end surface of the unblocking column 27, it can push off the impurities adhering to the surface of the unblocking column 27. Thus, the unblocking column 27 can be self-cleaned. When unblocking the next set of through holes 15, it can prevent impurities from adhering to the through holes 15 again, making the unblocking column 27 more effective for recycling. Furthermore, since the unblocking column 27 is in a state away from the threshing cylinder 14 when it completes one unblocking and returns to the initial position, the impurities will not fall into the collection box 20 and mix with the kidney bean seeds when the unblocking column 27 performs self-cleaning.By utilizing a self-dredging threshing mechanism, kidney beans can be automatically threshed, allowing for concentrated collection of seeds and facilitating subsequent processing. Simultaneously, the threshing process unblocks multiple sets of through-holes 15, preventing blockage by pods or other impurities and ensuring effective threshing. Furthermore, after each unblocking operation, the scraper ring group 28 and scraper 23 remove impurities from the surface of the unblocking column 27, achieving self-cleaning. This prevents impurities from re-adhering to the through-holes 15 when unblocking the next set, resulting in better reusability of the unblocking column 27. When kidney bean seeds adhere to the inner wall of the threshing cylinder 14, the motor 46 drives the gear 50 to rotate, which in turn causes the gear 51 to rotate, so that the end of the gathering plate 52 faces downward and is in contact with the inner wall of the threshing cylinder 14. Then, the threshing cylinder 14 and the gear 51 are driven to rotate simultaneously in opposite directions, so that the gathering plate 52 remains in its original position. When the inner wall of the threshing cylinder 14 moves relative to the end of the gathering plate 52, the gathering plate 52 will scrape the kidney bean seeds adhering to the inner wall of the threshing cylinder 14, so that the kidney bean seeds are gathered at the gathering plate 52, and the threshing cylinder 14 stops moving after rotating one revolution. At this time, since a row of through holes 15 is located at the bottom of the collecting plate 52, the kidney bean seeds gathered at the collecting plate 52 will fall out through the through holes 15. Furthermore, because there is a gap between adjacent through holes 15, if the kidney bean seeds remain within the gap between two through holes 15, they will not fall out. Therefore, the motor 54 can drive the lead screw 53 to rotate, causing multiple push blocks 45 to move simultaneously. Initially, two adjacent push blocks 45 are in contact with each other. When two adjacent push blocks 45 move away from each other, they will push the kidney bean seeds to the through holes 15, allowing them to fall out smoothly through the through holes 15. This avoids the situation where some kidney bean seeds adhere to the inner wall of the threshing cylinder 14, making collection difficult.
