Traditional straw disposal methods, such as burning and indiscriminate disposal, not only waste resources but also cause a series of problems such as environmental pollution and fire hazards.

[0003] Existing straw crushing devices have several shortcomings in practical applications. Firstly, some devices lack effective coordination between the crushing components and the conveying and auxiliary combing structures, resulting in a mismatch between the straw conveying speed to the crushing area and the crushing speed, leading to low crushing efficiency. Furthermore, due to the lack of effective straw combing, straw easily becomes entangled on the crushing components during the crushing process, affecting not only the crushing quality but also requiring frequent shutdowns for cleaning, severely restricting the device's continuous operation capability. Secondly, existing devices often lack the flexibility to adjust their internal structure to ensure efficient crushing of various types of straw. This results in poor adaptability to different farmland environments and straw usage requirements, limiting their application scope. Utility Model Content

[0023] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0024] This utility model provides an easily adjustable crop straw crushing device through improvements. The technical solution of this utility model is as follows:

[0025] like Figure 1 - Figure 6 As shown, an easily adjustable crop straw crushing device includes a trolley 1, a crushing chamber 2 fixedly connected to the upper surface of the trolley 1, a crushing component 3 rotatably connected to the inner wall of the crushing chamber 2, a support base 4 fixedly connected to the upper surface of the trolley 1, a motor 5 fixedly connected to the upper surface of the support base 4, two symmetrically arranged rotating plates 6 rotatably connected to the inner wall of the crushing chamber 2, a common conveyor belt 7 rotatably connected between the two rotating plates 6, connecting plates 8 fixedly connected to the side walls of both rotating plates 6, and a burr roller 9 rotatably connected between the two connecting plates 8.

[0026] Furthermore, the surface of the cart 1 is provided with a discharge port 10, which is connected to the crushing chamber 2. The discharge port 10 facilitates the discharge of the crushed straw. Returning the crushed straw to the field improves soil structure, increases soil fertility, and reduces the use of chemical fertilizers. Long-term excessive use of chemical fertilizers can lead to soil compaction and acidification, affecting crop growth. Crops may absorb excessive harmful substances, thus impacting food safety. Improved soil quality promotes healthy crop growth, ensuring the safety of agricultural products from the source and reducing the likelihood of health problems caused by consuming contaminated agricultural products.

[0027] Furthermore, the output end of the motor 5 is fixedly connected to the first transmission wheel 11, the right end of the transmission shaft of the crushing component 3 penetrates the inner wall of the crushing chamber 2 and extends to the outside, the right end of the transmission shaft of the crushing component 3 is fixedly connected to the second transmission wheel 12, and the surfaces of the first transmission wheel 11 and the second transmission wheel 12 are fitted with the same transmission belt 13.

[0028] Furthermore, the side walls of the two connecting plates 8 are rotatably connected to two symmetrically arranged first pulleys 14. One end of the first pulley 14 on the right is fixedly connected to the drive shaft of the burr roller 9, and one end of the first pulley 14 on the left is fixedly connected to the drive shaft on the right side of the conveyor belt 7. The surface of the two first pulleys 14 is fitted with the same first belt 15. The motor 5 drives the crushing component 3 to operate efficiently through the first drive wheel 11, the drive belt 13, and the second drive wheel 12, so that the straw is fully crushed in the crushing chamber 2.

[0029] Furthermore, the right end of the left drive shaft of the conveyor belt 7 passes through the side wall of the rotating plate 6 and extends to the outside. The right end of the left drive shaft of the conveyor belt 7 is fixedly connected to the second pulley 16. The left end of the drive shaft of the crushing component 3 passes through the inner wall of the crushing chamber 2 and extends to the outside. The right end of the drive shaft of the crushing component 3 is fixedly connected to the third pulley 17. The second pulley 16 and the third pulley 17 are fitted with the same second belt 18. The first pulley 14 and the first belt 15 on the two connecting plates 8 work together to drive the burr roller 9 and the conveyor belt 7 to rotate, so that the straw is combed during the conveying process, which helps to crush it better, improve the straw utilization efficiency, and the properly treated straw will not be piled up in the environment, reducing the breeding ground for bacteria and mosquitoes.

[0030] Furthermore, the side wall of the crushing chamber 2 and the side wall of the left rotating plate 6 are provided with the same square adjustment groove 19. The inner wall of the square adjustment groove 19 is slidably connected with a square locking block 20. The side wall of the crushing chamber 2 is threadedly connected with a bolt 21. The upper end of the bolt 21 abuts against the side wall of the square locking block 20. The adjustment structure composed of the square adjustment groove 19, the square locking block 20 and the bolt 21 on the side wall of the crushing chamber 2 and the left rotating plate 6 can adjust the position of the conveyor belt 7 and the burr roller 9 according to different scenarios.

[0031] Working principle: After the motor 5 starts, it drives the first transmission wheel 11 at the output end to rotate. The first transmission wheel 11 drives the second transmission wheel 12 to rotate through the transmission belt 13. Since the second transmission wheel 12 is fixed on the transmission shaft of the crushing component 3, the transmission shaft of the crushing component 3 starts to rotate, thereby driving the crushing component 3 to crush the crop straw in the crushing chamber 2. This transmission method ensures that the motor can stably provide power to the crushing component, achieving efficient crushing. When the transmission shaft of the crushing component 3 rotates, the third pulley 17 at its left end also rotates. The third pulley 17 drives the second pulley 16 to rotate through the second belt 18. The second pulley 16 is fixed on the transmission shaft on the left side of the conveyor belt 7, causing the conveyor belt 7 to start running and transport the crop straw to the crushing area. Simultaneously, the right drive shaft of the conveyor belt 7 drives the left first pulley 14 to rotate. The left first pulley 14, through the first belt 15, drives the right first pulley 14 to rotate, which in turn drives the burr roller 9 to rotate, assisting in combing the straw, preventing straw tangling, and ensuring the smooth progress of the crushing process. When it is necessary to adjust the position of the conveyor belt and the burr roller according to different crop straws, the tightness between the bolt 21 and the square clamp 20 can be changed by rotating the bolt 21. When the square clamp 20 is removed from the square adjustment groove 19, it drives the left rotating plate 6 and the conveyor belt 7 and the burr roller 9 connected to it to adjust their positions, so as to achieve the best crushing and conveying effect for crushing field straw into fertilizer or transporting straw back to a suitable site to make feed.

[0032] The foregoing description enables those skilled in the art to implement or use this invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of this invention. Therefore, this invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
