[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A straw chopping device for agricultural product feed processing includes a housing, with two grooves on the inner wall of the housing. An L-shaped plate is fixedly connected to the outside of the housing, and a drive assembly providing rotational capability is fixedly connected to the top of the L-shaped plate. A drive wheel is fixedly connected to the outside of the drive assembly. A driven shaft is rotatably connected to the inner wall of the housing, and a driven wheel is fixedly connected to the outside of the driven shaft. A conveyor belt is fitted around the outside of the driven wheel and the drive assembly. Two sliding plates are fixedly connected to the outside of the conveyor belt, and the sliding plates are slidably connected to the grooves on the inner wall of the housing. Two connecting blocks are fixedly connected to both sides of the conveyor belt, and connecting rods are fixedly connected to the outside of the two connecting blocks. A clamping assembly providing synchronous lifting capability is fixedly connected to the bottom of the connecting rods, and limit rings are fixedly connected to both ends of the connecting rods.

[0007] The aforementioned technical solution boasts efficient and stable cutting capabilities. Through the coordinated operation of the drive assembly and conveyor belt, straw can be quickly and evenly fed into the cutting zone, improving processing efficiency. Furthermore, the synchronous lifting design of the clamping assembly ensures adaptability to straw of different lengths and diameters, reducing operational difficulty and enhancing safety. The limit ring effectively prevents equipment deviation during operation, further enhancing the equipment's stability and reliability.

The design of the sliding grooves 2 allows the sliding plate 10 to move smoothly, ensuring that the straw on the conveyor belt 9 can smoothly enter the cutting area, improving cutting efficiency. An L-shaped plate 3 is fixedly connected to the outside of the housing 1. The L-shaped plate 3 provides a stable platform for installing the motor 4 and drive assembly, ensuring the stability and safety of the device during operation. A drive assembly providing rotational capability is fixedly connected to the top of the L-shaped plate 3. A drive wheel 6 is fixedly connected to the outside of the drive assembly. A driven shaft 7 is rotatably connected to the inner wall of the housing 1, ensuring the stability and continuity of the conveyor belt 9 during operation and coordinating the movement of the straw. A driven wheel 8 is fixedly connected to the outside of the driven shaft 7, responsible for receiving power from the drive assembly and ensuring the normal operation of the conveyor belt 9. A conveyor belt 9 is fitted around the driven wheel 8 and the drive assembly, conveying the straw to be cut to the cutting assembly, providing efficient and continuous operation. Two sliding plates 10 are fixedly connected to the outside of the conveyor belt 9 to ensure stable straw transport and prevent deviation or jamming during movement. The sliding plates 10 are slidably connected to a groove 2 on the inner wall of the outer casing 1. Two connecting blocks 11 are fixedly connected to both sides of the conveyor belt 9 to ensure that the clamping assembly can rise and fall synchronously as the conveyor belt 9 moves, effectively clamping the straw. Connecting rods 12 are fixedly connected to the outside of the two connecting blocks 11, providing the necessary strength and stability to ensure the effectiveness of the clamping action. A clamping assembly providing synchronous rising and falling capability is fixedly connected to the bottom of the connecting rod 12.

[0042] The drive assembly includes a motor 4 and a drive shaft 5. The motor 4 provides power, which is transmitted to a drive wheel 6 via the drive shaft 5. The drive wheel 6 is connected to a conveyor belt 9, and its rotation drives the movement of the conveyor belt 9, which is responsible for transporting the straw to the cutting assembly. This drives the entire conveyor belt 9, allowing the straw to be fed into the cutting area. The bottom of the motor 4 is fixedly connected to the top of the L-shaped plate 3, and the output end of the motor 4 is fixedly connected to the drive shaft 5. The clamping assembly includes two cylinders 14 and clamping blocks 15. The tops of the two cylinders 14 are fixedly connected to the bottom of the connecting rod 12, and the output ends of the two cylinders 14 are fixedly connected to the clamping blocks 15, enabling the clamping and release of the straw and ensuring its stability during cutting. A second outer shell 16 is fixedly connected to the outer shell 1, providing protection against flying debris during cutting and ensuring the overall structural stability of the equipment. A cutting assembly providing lifting capability is fixedly connected to the inner wall of the outer casing 16. The inner wall of the cutting assembly has two sliding grooves. The cutting assembly includes two cylinders 17, a connecting plate 18, bolts 19, and a pressure plate 20. The pressure plate 20 ensures that the straw does not move during the cutting process by pressing the cutting blade. Simultaneously, the design of the sliding grooves 21 allows the chaff cutter 24 to perform necessary up-and-down movements. The bottoms of the two cylinders 17 are fixedly connected to the inner wall of the outer casing 16. The output ends of the two cylinders 17 are fixedly connected to the connecting plate 18. Two bolts 19 are threaded onto the external surface of the connecting plate 18, and the pressure plate 20 is threaded onto the external surface of the two bolts 19.

[0043] Two sliding grooves 21 are provided on the inner walls of both sides of the pressure plate 20. The sliding grooves 21 allow the limiting bolts 23 to slide freely within the pressure plate 20, thereby enabling the guillotine 24 to flexibly adjust the cutting depth and angle, ensuring the accuracy of the cutting. Two rotating bolts 22 are threaded to the outer sides of both ends of the pressure plate 20. Two guillotines 24 are slidably connected to the inner wall of the pressure plate 20. These are the main cutting components, responsible for cutting the straw conveyed on the conveyor belt 9 into the required short segments. Two limiting bolts 23 are threaded to the top of the guillotine 24. The outer sides of the limiting bolts 23 are slidably connected to the sliding grooves 21 provided on the inner wall of the pressure plate 20. Both ends of the connecting rod 12 are fixedly connected to wind baffles 25. The two wind baffles 25 are located on the same horizontal plane. Two feet 26 are fixedly connected to the bottom of the outer shell 1 and the bottom of the outer shell 2 16. A sealing plate 27 is detachably connected to the outer side of the outer shell 2 16. Multiple fixing bolts 28 are passed through and connected to the outer side of the sealing plate 27 and the inner wall of the outer shell 2 16.

[0044] Working principle: Before starting the device, the operator checks whether the bolts on the chaff cutter 24 are loose. The straw is placed on the conveyor belt 9. The motor 4 is started, driving the drive shaft 5 to rotate. The drive shaft 5 drives the drive wheel 6 to rotate, thus driving the conveyor belt 9. The conveyor belt 9 drives the drive wheel 6 on the other side to rotate, thus driving the driven wheel 8 to rotate, achieving stable transmission on the conveyor belt 9. The starting cylinder 14 drives the clamping block 15 to press down, holding the straw in place. Simultaneously, the conveyor belt 9 moves, driving the straw... The sliding plate 10 moves, thus ensuring the stable transport of straw. The straw placed on the conveyor belt 9 is slowly transported by the conveyor belt 9 to the top of the outer shell 16. First, the two rotating bolts 22 are rotated to abut against the two guillotine blades 24, which slide inside the shell 16. After adjusting to a suitable distance, the limiting bolt 23 is rotated to the top of the shell 16 to clamp the guillotine blades 24. When the appropriate distance is adjusted, the straw is transported to the top of the outer shell 16. Then, the cylinder 17 is activated to perform a reciprocating lifting motion, which drives the guillotine blades 24 to cut the straw.

[0045] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
