[0002] Agricultural products are items produced in agriculture, such as sorghum, rice, peanuts, corn, wheat, and local specialties. The state stipulates that primary agricultural products refer to plants, animals and their products obtained from agricultural activities, excluding processed products.

[0003] According to Chinese Patent Publication No. CN221863628U, a scissor-like device for primary processing of agricultural products relates to the field of primary processing technology for agricultural products. The device includes a main body with two connecting frames at one end. A tray is located on the side of the two connecting frames that are close together. A second rotating shaft is rotatably connected to the side of the two connecting frames that are close together. A bucket is located on the outer side of the second rotating shaft, and a driven gear is located at one end of the second rotating shaft. A fixed frame is located on one side of each connecting frame, and a third motor is located on the inner side of the fixed frame. The output end of the third motor movably passes through the connecting frame and is connected to a driving gear. This invention uses the third motor to drive the driving gear to rotate, which in turn drives the driven gear and the second rotating shaft to rotate. This allows the bucket to scoop up the straw piled on the ground and flip it onto the tray for storage, thereby achieving efficient straw collection and sorting, reducing the burden of manual collection, saving labor costs, and improving work efficiency.

[0018] The present invention, by adopting the above technical solution, can bring the following beneficial effects:

[0019] 1. This scissor-bar device for primary processing of agricultural products uses a first motor to drive a drive shaft to rotate. The drive shaft, through components such as a surrounding groove and a moving rod, causes a first swinging rod to swing, which in turn drives a fixed cylinder and a movable rod, allowing the striking head to beat and thresh the rice. Simultaneously, the drive shaft drives a second rotating rod to rotate through a synchronous pulley, allowing the striking head to rotate while striking, greatly increasing the contact with the rice, significantly improving the threshing effect, greatly increasing efficiency, eliminating the need for subsequent manual threshing, and improving work efficiency.

[0020] 2. This type of shearing device for primary processing of agricultural products, by setting up a crushing mechanism, when rice falls into the discharge plate, the driven shaft drives the fifth rotating rod to rotate, and through the connecting column, the fourth rotating rod drives the crushing roller to rotate, crushing and threshing the rice. This, combined with the knocking threshing, further improves the thoroughness of threshing and reduces rice residue.

[0021] 3. This type of shearing device for primary processing of agricultural products, by setting elastic strips on the conveyor belt, allows the threshed rice to slide smoothly. The crushed rice falls into the filter screen through the discharge port. The cam on the fifth rotating rod strikes the filter screen, which helps to filter out impurities and allows the clean rice to fall into the collection box below for convenient subsequent collection and processing, ensuring the purity of the rice. At the same time, the guide plate swings under the drive of the driven shaft, shaking the rice to thresh it, and removing the loosened rice from the rice, improving the stability of threshing.

[0022] 4. This type of shearing device for primary processing of agricultural products, by setting up a shearing mechanism, enables a second motor to drive a rotating block to rotate, thereby causing the connecting plate and movable teeth to reciprocate, cooperating with the fixed teeth to achieve the shearing operation of rice. The rice after shearing falls directly onto the conveyor belt for the subsequent threshing process, realizing the integration of shearing and threshing, reducing manual operation steps, and improving the overall processing efficiency.

[0023] 5. This type of shearing device for primary processing of agricultural products, by setting a connecting pipe, can drive the elastic plate to move back and forth when the movable teeth move back and forth. The elastic plate drives the rice to shake, thereby shaking the rice grains off. At the same time, it can also increase the striking range of the striking head and make the striking more uniform.

The second rotating rods 410 on the same side are connected by a synchronous belt pulley. A driven shaft 418 is rotatably connected to the frame 3. A conveyor belt 413 is sleeved on the drive shaft 42 and the driven shaft 418. An elastic strip 414 is provided on the conveyor belt 413. A third rotating rod 415 is rotatably connected to the frame 3. A guide plate 416 is fixedly sleeved on the third rotating rod 415. A second swing rod 417 is fixedly sleeved on the third rotating rod 415. A first rotating disk is fixedly connected to one end of the driven shaft 418, and the first rotating disk is slidably connected to the inner wall of the second swing rod 417. Frame 4 A ramp is fixedly connected to the top of frame 4, and a feed plate 5 is fixedly connected to the inner wall of frame 3, with the top of feed plate 5 fixedly connected to the bottom of ramp. A crushing mechanism 6 is provided on frame 3, which includes a discharge plate 61, a fourth rotating rod 62, a crushing roller 63, a fifth rotating rod 64, and a connecting column 65. The discharge plate 61 is fixedly connected to the inner wall of frame 3 and has a discharge port. The fourth rotating rod 62 is rotatably connected to frame 3, and the crushing roller 63 is fixedly sleeved on the fourth rotating rod 62, with protruding ridges on the crushing roller 63.

A collection box 7 is provided on the inner wall of the frame 3, and the collection box 7 is positioned directly below the filter screen 67.

[0040] Working principle: The first motor 41 drives the drive shaft 42 to rotate, which in turn conveys the rice upwards via the conveyor belt 413. When the drive shaft 42 rotates, it drives the moving rod 48 to move back and forth via the surrounding groove 43. This movement of the moving rod 48 causes the first swing rod 46 to swing, which in turn causes the first rotating rod 45 to rotate, which in turn causes the fixed cylinder 49 to swing. The swinging of the fixed cylinder 49 causes the movable rod 411 to swing, thus striking the rice with the striking head 412 to thresh it. Simultaneously, the rotation of the drive shaft 42 drives the second rotating rod 410 to rotate via the synchronous belt pulley. The rotation of the second rotating rod 410, through the universal joint coupling, drives the movable rod 411 to rotate, causing the striking head 412 to rotate while striking the rice, increasing the contact between the striking head 412 and the rice, thereby improving the threshing effect. The threshed rice slides down the inclined surface of the elastic strip 414 onto the feed plate 5, and then further slides down the feed plate... When rice is conveyed above the conveyor belt 413, it falls onto the discharge plate 61 under the action of the guide plate 416. When the rice comes into contact with the guide plate 416, the driven shaft 418 drives the second swing rod 417 to swing, which in turn drives the guide plate 416 to swing through the third rotating rod 415. This further shakes the rice and threshes it. When the rice falls onto the discharge plate 61, the driven shaft 418 drives the fifth rotating rod 64 to rotate through the synchronous belt pulley, which in turn drives the fourth rotating rod 62 to rotate through the connecting column 65. The fourth rotating rod 62 drives the crushing roller 63 to rotate, crushing and threshing the rice. The threshed rice falls onto the filter screen 67 through the discharge port. The rotation of the fifth rotating rod 64 drives the cam 66 to rotate, striking the filter screen 67. The rice that has passed through the filter screen 67 falls into the collection box 7 for collection.

[0041] Please see Figure 1-10Based on the above embodiments, in another preferred embodiment of the present invention, the frame 3 is provided with a shearing mechanism 8, which includes a second motor 81, a rotating block 82, a connecting plate 83, a movable tooth 84, and a fixed tooth 89. The second motor 81 is fixedly installed inside the protective frame on the right side. The rotating block 82 is fixedly connected to the output end of the second motor 81. The connecting plate 83 movably penetrates the outer wall of the frame 3, and the inner wall of the connecting plate 83 is movably connected to the rotating block 82. The movable tooth 84 is fixedly connected to one side of the connecting plate 83. The fixed tooth 89 is fixedly connected to the inner wall of the frame 3, and the top of the fixed tooth 89 is slidably connected to the bottom of the movable tooth 84. A fixed rod 85 is fixedly connected to the frame 44. A movable cylinder 86 is movably sleeved on the fixed rod 85. An elastic sheet 87 is fixedly connected to the movable cylinder 86. A connecting block 88 is fixedly connected to the movable tooth 84, and the connecting block 88 is fixedly connected to the movable cylinder 86.

[0042] Working principle: The second motor 81 is started to drive the rotating block 82 to rotate. The rotation of the rotating block 82 will drive the connecting plate 83 to move back and forth, thereby driving the movable tooth 84 to move back and forth. In cooperation with the fixed tooth 89, the rice is cut off. The cut rice will fall onto the conveyor belt 413 for conveying. At the same time, the reciprocating movement of the movable tooth 84 will drive the movable cylinder 86 to move back and forth through the connecting plate 83, thereby driving the elastic sheet 87 to move back and forth. The elastic sheet 87 shakes the bag and shakes the rice off the rice.
