The grass collection plate has a rotating shaft located at the bottom of the box body near the harvester and rotatably connected to the box body. From top to bottom, the side wall of the box body is equipped with a traction pulley, a support bar, and a traction pipe. One end of the support bar is threaded to the box body, and the other end is threaded to the traction pulley. The traction pipe contains a counterweight that moves vertically. The rotating shaft, traction pulley, and counterweight are connected sequentially by a traction rope.

[0007] Preferably, the grass collecting plate is arranged in a fence shape, and the grass collecting plate includes a plurality of grass collecting rods, which are welded to a rotating shaft.

[0014] The technical solution provided by this utility model has the following beneficial effects:

[0015] 1. This utility model, by setting a counterweight, traction rope, traction pulley, and grass collection plate on the grass collection box, connects the grass collection box to the discharge port of the harvester. During harvesting, straw and grass continuously enter the grass collection box. When a certain weight is reached, the gravity provided by the counterweight is insufficient to keep the grass collection plate closed. Therefore, the grass collection plate opens, causing the straw and grass to gather into a pile and fall to the ground. Then the counterweight closes the grass collection plate again. This process is repeated, which can automatically collect straw and grass into a pile during harvesting, improving the collection efficiency of workers.

[0016] 2. This utility model ensures that the weight of each straw pile is approximately equal by setting a counterweight, making collection more convenient. Attached Figure Description

[0024] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0025] Please see Figures 1 to 3 This invention relates to a preferred embodiment of a combine harvester grass collection box for use at the grass discharge port. The box includes a body 1, one side of which is open and movably connected to the combine harvester's grass discharge port. The bottom of the body 1 is also open and has a rotatable grass collection plate 2. The grass collection plate 2 has a rotating shaft 21, located at the bottom of the body 1 near the combine harvester's grass discharge port and rotatably connected to the body 1. From top to bottom, the side wall of the body 1 is sequentially equipped with a traction pulley 4, a support bar 5, and a traction pipe 6. One end of the support bar 5 is fixedly connected to the body 1, and the other end is fixedly connected to the traction pulley 4. The traction pipe 6 contains a counterweight 7 that moves vertically. The rotating shaft 21, the traction pulley 4, and the counterweight 7 are sequentially connected by a traction rope 8. Since the combine harvester's grass discharge port is generally rectangular, the grass collection box in this invention is a cuboid, with an overall length of 91cm, a width of 61cm, and a height of 62cm. The counterweight 7... The cylindrical body is made of iron rod. The weight of the counterweight 7 can be adjusted according to actual needs. The weight of this utility model is 3kg. In the normal state, the counterweight 7, due to gravity, stretches the grass collecting plate 2 through the traction rope 8 and traction pulley 4 to prevent the grass collecting plate 2 from rotating, keeping the bottom of the grass collecting box closed. As the harvester starts working, the amount of straw inside the grass collecting box increases. As the amount of straw increases, the weight on the grass collecting plate 2 increases, causing the weight provided by the counterweight 7 to be insufficient to keep the grass collecting plate 2 closed. Then the grass collecting plate 2 opens, and the straw inside gathers into a pile and falls into the field. After the straw falls, the counterweight 7 closes the grass collecting plate 2 again, waiting for the straw to gather again. This cycle repeats, which can gather the straw into a pile for easy collection by workers. The grass collecting box realizes the automatic opening and closing of the grass collecting plate 2 through the linkage mechanism of the counterweight 7, traction rope 8 and traction pulley 4. As straw and other debris accumulate, the straw collection plate 2 will automatically open and close automatically after the debris falls off, reducing the need for manual intervention and improving work efficiency. The entire device has a simple structure, mainly composed of the straw collection plate 2, traction pulley 4, counterweight 7 and traction rope 8. It has no complex mechanical parts, so the failure rate is low and the maintenance cost is low, making it suitable for long-term use in farmland environments.

[0026] Please refer to Figure 1The grass collection plate 2 is arranged in a fence-like shape and includes several grass collection rods 22, which are welded to a rotating shaft 21. The rotating shaft 21 is L-shaped, which makes the grass collection plate 2 more flexible in opening and closing, reduces rotational resistance, and ensures that the grass collection plate 2 can respond quickly to changes in the weight of debris, achieving automatic opening and closing. The fence-like design can remove dust and debris in time, resulting in cleaner collected straw suitable for feeding, reducing material consumption, and lowering the overall weight, making the grass collection box lighter during operation. When the fence-like design of the grass collection plate 2 is opened, straw and other debris can more easily slide off the grass collection rods 22, reducing the possibility of straw residue and facilitating the cleaning and maintenance of the grass collection box. Both the rotating shaft 21 and the grass collection rods 22 are made of steel bars, with the steel bars of the rotating shaft 21 being thicker than those of the grass collection rods 22, ensuring the strength and durability of the grass collection plate 2 when bearing the weight of straw and other debris, effectively preventing deformation or breakage, and extending its service life.

[0027] Please refer to Figures 1 to 3 The rotating shaft 21 includes a traction part 23 and a rotating part 24, which are integrally formed. Bearing holes 11 are provided at both ends of the bottom of the housing 1. The rotating part 24 passes through the bearing holes 11 and is rotatably connected to the housing 1. The traction part 23 is connected to the traction pulley 4 and the counterweight 7 via a traction rope 8. The bearing holes 11 are cylindrical, and the rotating part 24 passes through the cylindrical bearing holes 11, making the rotation of the rotating shaft 21 at the bottom of the housing 1 smoother, reducing frictional resistance, and ensuring the flexibility and stability of the grass collection plate 2 during opening and closing. The cylindrical bearing hole design of the rotating part 24 ensures smooth rotation of the shaft during rotation. The bearing hole 11 has a uniform contact area, which reduces local wear and extends the service life of the bearing hole 11 and the rotating shaft 21. The traction part 23 is connected to the traction pulley 4 and the counterweight 7 through the traction rope 8, so that the grass collecting plate 2 is subjected to uniform force during opening and closing, avoiding wear or damage caused by local stress concentration and extending the service life of the grass collecting plate 2. The traction part 23 is connected to the counterweight 7 through the traction rope 8. The weight of the counterweight 7 can be adjusted according to actual needs, thereby precisely controlling the opening and closing force of the grass collecting plate 2 and ensuring that the grass collecting plate 2 can open in time when the straw weight reaches a certain level, avoiding opening and closing too early or too late.

[0028] For details, please refer to Figure 1 The spacing between several straw collecting rods 22 is 3cm-7cm. In this embodiment, the spacing between the straw collecting rods is set to 5cm. The spacing is moderate, which can effectively bear straw and other debris, and allow dust or debris to slide out from the gaps, ensuring that the straw can be collected smoothly. It is suitable for most farmland environments and can meet the straw collection needs after different crops are harvested.

[0029] For details, please refer to Figure 1The side wall of the box 1 is provided with a support plate 3, and the support bar 5 is threadedly connected to the support plate 3. The traction pipe 6 is welded to the lower end of the support plate 3. The support plate 3 can effectively disperse the force and vibration of the grass collection box during operation, and improve the overall stability of the grass collection box. The support bar 5 is fixed to the support plate 3 by threaded connection. This connection method is both firm and easy to disassemble, which enhances the load-bearing capacity of the side wall of the grass collection box. The support plate 3 can evenly distribute the force transmitted by the traction pipe 6 and the support bar 5 to the side wall of the grass collection box, avoiding deformation or damage to the side wall caused by local stress concentration. The traction pipe 6 is welded to the lower end of the support plate 3, which ensures the connection strength between the traction pipe 6 and the support plate 3 and prevents the traction pipe 6 from loosening or falling off during operation.

[0030] For details, please refer to Figure 1 The traction unit 23 and the counterweight 7 are equipped with traction rings 9 at their ends. The traction rope 8 passes through the traction ring 9 to connect the traction unit 23, the traction pulley 4, and the counterweight 7. The traction ring 9 makes the connection between the traction rope 8 and the traction unit 23 and the counterweight 7 more secure, preventing the traction rope 8 from falling off or loosening during operation, ensuring the stability of the opening and closing process of the straw collection plate 2. At the same time, it makes the installation and disassembly of the traction rope 8 more convenient, facilitating the assembly, maintenance, and replacement of parts of the straw collection box. The design of the traction ring 9 makes the tension transmission of the traction rope 8 more precise, ensuring that the straw collection plate 2 can open in time when the weight of the debris reaches a certain level, avoiding opening and closing too early or too late. The connection method between the traction ring 9 and the traction rope 8 allows the straw collection plate 2 to automatically adjust its opening and closing state according to the change of straw weight, without manual intervention, realizing fully automated operation.

[0031] For details, please refer to Figure 1 The top of the box 1 is provided with an installation slot 12, which fits snugly against the upper edge of the combine harvester's grass discharge port. The design of the installation slot 12 can be adjusted according to the size of the grass discharge port of different models of combine harvesters, and has strong versatility and adaptability. In this utility model, the width of the installation slot 12 is 12cm. The design of the installation slot 12 allows the grass collection box to be quickly aligned with the combine harvester's grass discharge port, and the installation process is simple and convenient, saving installation time.

[0032] The working principle of the straw collection box for the straw discharge port of a combine harvester provided by this utility model is as follows: In normal state, due to the gravity of the counterweight 7, the rotating shaft 21 is controlled by the traction rope 8 to prevent it from rotating, that is, the straw collection plate 2 is closed. When the straw in the straw collection plate 2 gradually accumulates to the set weight, the straw collection plate 2 rotates through the rotating shaft 21, driving the counterweight 7 upward, the straw collection plate 2 opens, and the straw inside falls to the ground and piles up. Then, as the weight in the straw collection plate 2 disappears, the counterweight 7 moves downward, and the rotating shaft 21 is driven to rotate through the traction rope 8, closing the straw collection plate 2, waiting for the next straw accumulation. This cycle is repeated to complete the collection of straw to the ground and pile it up.

[0033] In summary, this utility model, by setting up a counterweight 7, a traction rope 8, a traction pulley 4, and a grass collection plate 2 on the grass collection box, connects the grass collection box to the discharge port of the combine harvester. During harvesting, straw and grass continuously enter the grass collection box. When a certain weight is reached, the gravity provided by the counterweight 7 is insufficient to keep the grass collection plate 2 closed, so the grass collection plate 2 opens, causing the straw and grass to fall to the ground and gather into a pile. Then the counterweight 7 closes the grass collection plate 2 again, and so on, so that the straw and grass can be automatically collected into a pile during harvesting, improving the collection efficiency of the workers.

[0034] The present invention has been described above with reference to the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
