Description

Technical Field

[0001] The present invention relates to the technical field of soybean combine harvesters, and particularly to an anti - pod - bursting soybean combine harvester. Background Art

[0002] A soybean combine harvester is a modern agricultural machine integrating functions such as cutting, conveying, threshing, separating, and cleaning. It cuts soybean plants through a cutter bar and conveys them to a threshing device for threshing, and then separates and cleans the soybean grains and impurities to achieve mechanized soybean harvesting. The soybean combine harvester greatly improves the efficiency of soybean harvesting, reduces the labor intensity of farmers, and has a profound impact on the large - scale and mechanized production of soybeans.

[0003] In a soybean combine harvester, the reel plays a crucial role. The main functions of the reel include: moving the crops in front of the cutter bar onto the cutter, supporting the crop straws to prevent the crop straws from tilting forward during cutting by the cutter, and promptly pushing the crop straws onto the conveyor after cutting. There are various structural types of reels, including ordinary pressing - plate type and eccentric type, etc., which are usually composed of components such as reel plates, stay bars, and bearings. By adjusting the position and rotation speed of the reel, it can adapt to different harvesting conditions to ensure the harvesting efficiency and effect.

[0004] In the existing soybean combine harvesters, although the efficiency of soybean harvesting has been improved to a certain extent, there are still some drawbacks. Among them, while the reel plays a role in supporting and conveying the crop straws, due to its rotation and hitting actions, it will generate a certain impact force on the soybean plants, resulting in strong vibrations of the stems and pods. Especially in the late stage of full maturity of soybeans, the pods have become dry and fragile, and this kind of vibration is extremely likely to cause the pods to burst, resulting in pod - bursting phenomenon, and further causing the loss of soybean grains, increasing the harvesting loss.

[0016] The beneficial effects of a soybean combine harvester for preventing pod explosion proposed by the present invention are as follows:

[0017] 1. The soybean combine harvester of the present invention can drive the collection trough to move. By using the second motor to drive the sprocket to rotate through the second connecting rod, the chain can be made to drive the connecting block to move along a square. Thus, the connecting block can drive the stretching rod to move along the square through the support rod and the square cross beam. Therefore, the stretching rod moving along the square can straighten the soybean straw or lift the soybean straw in a lying-down state.

[0018] 2. The present invention uses the second motor to drive the worm to rotate through the second connecting rod, the fourth pulley, the fifth pulley and the second belt. The rotation of the worm can cause the worm wheel to drive the second rotating rod to rotate. Thus, the second rotating rod can drive the toothless gear and the gear on its outer wall to rotate. Since the two gears are meshed, the cooperation between the two gears can be used to make the first rotating rod drive the toothless gear on its outer wall to rotate in the opposite direction to the toothless gear on the outer wall of the second rotating rod. Furthermore, the cooperation between the two toothless gears and the rack can be used to make the first cutting knife move reciprocally left and right. Therefore, the first cutting knife and the second cutting knife moving reciprocally left and right can cut the soybean straw.

[0019] 3. As the soybean combine harvester moves, the guiding rod can be used to guide the cut soybean straw to move towards the flipping roller. The cooperation between the first motor, the first connecting rod, the first pulley, the second pulley, the third pulley and the first belt can make the spiral conveyor rod and the flipping roller rotate clockwise. Thus, the flipping roller rotating clockwise can drive the flipping rod on its outer wall to rotate clockwise with the flipping roller as the center. Therefore, the flipping rod rotating clockwise can lift the soybean straw clamped between the guiding rods, flip it into the inner cavity of the collection trough, and use the shielding groove to shield the soybean straw on the outer wall of the flipping rod to prevent the soybean straw from continuously flipping with the flipping rod. Thus, the soybean straw can be made to fall into the inner cavity of the collection trough. The rotating spiral conveyor rod can be used to start the soybean straw in the inner cavity of the collection trough to move to the feeding port. Under the action of the pneumatic conveying device of the soybean combine harvester itself, the soybean straw in the inner cavity of the collection trough can be made to move into the inner cavity of the feeding port, and the soybean combine harvester can perform subsequent operations on the soybean straw.

[0020] 4. This device can effectively reduce the phenomenon of soybean pod explosion caused by the action of the reel during the harvesting process, significantly reduce the loss rate of soybean grains, improve the overall efficiency of soybean harvesting and crop yield, and at the same time optimize the stability and reliability of the harvesting operation, bringing higher economic benefits to soybean growers and further promoting the development process of soybean agricultural mechanized harvesting.

[0040] The detailed connection means are well-known technologies in the art. The following mainly introduces the working principle and process. The specific work is as follows.

[0041] During use, start the first motor 16 and the second motor 98. The rotation of the output end of the first motor 16 can drive the first connecting rod 17 to rotate, thereby causing the third pulley 18 to rotate. Thus, the cooperation among the first belt 19, the first pulley 5, and the second pulley 14 enables the spiral conveyor rod 4 and the turning roller 12 to rotate clockwise. The rotation of the output end of the second motor 98 can drive the sprocket 96 and the fourth pulley 99 to rotate through the second connecting rod 95. The rotation of the sprocket 96 can cause the chain 97 to move along a square. Furthermore, the chain 97 moving along the square can drive the square crossbeam 91 to move along the square through the connecting block 94 and the support rod 93, thereby driving the stretching rod 92 to move along the square. The rotation of the fourth pulley 99 can drive the worm 910 to rotate through the second belt 912 and the fifth pulley 911. The rotation of the worm 910 can cause the worm gear 919 to drive the second rotating rod 917 to rotate. The second rotating rod 917 can be used to drive the toothless gears 918 and the gear 920 on its outer wall to rotate. The cooperation between the two gears 920 can cause the first rotating rod 916 to drive the toothless gear 918 on its outer wall to rotate in the opposite direction to the toothless gear 918 on the outer wall of the second rotating rod 917. Furthermore, the cooperation among the two toothless gears 918 and the rack 914 can cause the rack 914 to drive the first cutting knife 915 to perform a reciprocating left-right movement. Start the soybean combine harvester 1, and use the soybean combine harvester 1 to drive the collection trough 2 to move forward. As the collection trough 2 moves forward, the soybean straw will be inserted into the gaps between several guide rods 15, and the two stretching rods 92 moving along the square can straighten the soybean straw or lift up the soybean straw in a lying-down state. When the soybean straw moves to the first cutting knife 915 and the second cutting knife 921, the cooperation between the reciprocating left-right movement of the first cutting knife 915 and the second cutting knife 921 can cut the soybean straw. As the collection trough 2 moves forward, it will cause the cut soybean straw to move along the outer wall of the guide rod 15 towards the turning roller 12 until it reaches the turning roller 12. The clockwise rotating turning rod 13 can lift up the cut soybean straw and turn it into the inner cavity of the collection trough 2. At the same time, the shielding groove 6 can shield the soybean straw to ensure that the soybean straw on the outer wall of the turning rod 13 can fall into the inner cavity of the collection trough 2. The rotating spiral conveyor rod 4 can guide the soybean straw in the inner cavity of the collection trough 2 to the feeding port 3. The pneumatic conveying system of the soybean combine harvester 1 itself can suck the soybeans and soybean straw at the feeding port 3 into the soybean combine harvester 1 through the feeding port 3 for subsequent processing. This device can effectively reduce the phenomenon of soybean pod explosion caused by the action of the reel during the harvesting process, significantly reduce the loss rate of soybean grains, improve the overall efficiency of soybean harvesting and crop yield, and at the same time optimize the stability and reliability of the harvesting operation, bringing higher economic benefits to soybean growers and further promoting the development process of soybean agricultural mechanized harvesting.
