[0032] A movable plate 24 is fixedly mounted on one end of the limiting rod 23 , a baffle 22 is fixedly mounted on the other end of the limiting rod 23 , and fixing frames 20 are fixedly mounted on opposite sides of the two pressure plates 11 , and a spring 19 is fixedly connected between the fixing frame 20 and the corresponding baffle 22 .

[0033] The crushing mechanism includes a crushing shaft 15, and the number of the crushing shafts 15 is two. The two crushing shafts 15 are rotatably installed above the inside of the crushing box 3. A protective box 6 is fixedly installed on one side of the crushing box 3. One end of the crushing shaft 15 passes through one side of the inner wall of the crushing box 3 and extends to the inside of the protective box 6. A worm wheel 8 is fixedly installed on the outer wall of one end of the two crushing shafts 15. A worm 18 is rotatably installed inside the protective box 6, and the worm 18 is meshed with the worm wheel 8. A first motor 7 is fixedly installed at the bottom of the protective box 6, and the driving end of the first motor 7 passes through the bottom of the protective box 6 and extends to the inside of the protective box 6 and is fixedly connected to the bottom end of the worm 18. A plurality of crushing blades 16 are fixedly installed on the outer wall of the crushing shaft 15. The rotation of the two groups of crushing blades 16 will crush the straw very comprehensively, thereby improving the uniformity of the straw crushing.

[0034] In one embodiment, the adjustment mechanism includes a mounting frame 12, and the mounting frame 12 is fixedly installed at the bottom of the crushing box 3, a second motor 21 is fixedly installed on the mounting frame 12, a rotating shaft 17 is rotatably installed on the top of the partition 25, and the bottom end of the rotating shaft 17 passes through the top of the partition 25 and the bottom of the crushing box 3 in sequence and extends to the inside of the mounting frame 12 and is fixedly connected to the driving end of the second motor 21, and the top end of the rotating shaft 17 is fixedly connected to the lower side of the outer wall of the guide pipe 13, thereby achieving the effect of adjusting the position of the discharge end of the guide pipe 13, so as to facilitate the discharge of the crushed straw into the designated chamber.

[0035] In one preferred embodiment, a material guide cover 4 is fixedly installed at the top opening of the crushing box 3 .

[0036] In one embodiment, the crushing blades 16 on the two crushing shafts 15 are installed in a staggered arrangement, which helps to improve the crushing efficiency and uniformity.

[0037] In one preferred embodiment, the guide tube 13 is composed of a section of inclined tube and a section of vertical tube, and the rotating shaft 17 and the center of the vertical tube section on the guide tube 13 are on the same vertical line, ensuring that the rotation of the rotating shaft 17 can stably drive the guide tube 13 to rotate.

[0038] The working principle of the utility model is as follows: when the straw is crushed, the first motor 7 is controlled to start working, and the driving end of the first motor 7 drives the worm 18 to rotate. Through the meshing of the worm 18 and the worm wheel 8, the two crushing shafts 15 can be driven to rotate at the same time. The rotation of the crushing shaft 15 drives the crushing blades 16 to rotate. The rotation of the two sets of crushing blades 16 will crush the straw very comprehensively. The crushed straw enters the interior of the guide cover 14, and enters the interior of the guide pipe 13 through the guidance of the guide cover 14. After being guided by the guide pipe 13, it falls to one side of the partition 25. As the straw is discharged, the amount of straw on one side of the partition 25 will increase. When it reaches a certain amount, the second motor 21 is controlled to start working. The driving end of the second motor 21 drives the rotating shaft 17 to rotate, and the guide pipe 13 is driven to rotate through the rotating shaft 17. The discharge end of the guide pipe 13 is adjusted to discharge the crushed straw to the other side of the partition 25. At this time, the hydraulic telescopic rod 10 on one side of the partition 25 is controlled to start working. The driving end of the hydraulic telescopic rod 10 drives the pressing plate 11 to move into the inside of the crushing box 3. In the process of moving into the inside of the crushing box 3, the pressing plate 11 will move on the outer wall of the limit rod 23 As the movable plate 24 is limited by the partition plate 25, the movement of the pressing plate 11 will compress the spring 19 through the fixed frame 20, and the pressing plate 11 gradually approaches the movable plate 24 to compress the straw collected between the pressing plate 11 and the movable plate 24 into blocks. After the straw is compressed, the pressing plate 11 is controlled to reset. During the resetting process of the pressing plate 11, until the pressing plate 11 enters the inside of the discharge port 9 and contacts the baffle 22, the pressing plate 11 continues to move toward the outside of the crushing box 3, and the pressing plate 11 will drive the movable plate 24 to move through the baffle 22 and the limiting rod 23, and the movable plate 2 The movement of 4 will directly push the squeezed straw into blocks out of the discharge port 9. A collection box can be placed under the discharge port 9 in advance. The blocks of straw will fall directly into the collection box. The pressure plate 11 will be reset and the movable plate 24 will be effectively reset under the elastic support of the spring 19. The next discharge of the guide tube 13 will be waited for. The device divides the lower part of the crushing box 3 into two chambers through the partition 25. Through the adjustability of these two chambers and the guide tube 13, the crushed straw can be discharged alternately into the two chambers. For the straw discharged into the chamber, the device can automatically compress it into blocks and discharge it. This automatic discharge function greatly simplifies the operation process. The staff does not need to clean the straw manually, but can focus on other tasks, thereby improving work efficiency. In addition, the automatic compression function also effectively avoids the problem of the crushed straw occupying too much space, saving storage space and reducing resource consumption.

[0039] During the straw feeding process, the straw passes through the interior of the material guide cover 4 and enters the interior of the crushing box 3 for crushing. The material guide cover 4 has a shielding effect to prevent the straw splashed during the crushing process from directly splashing upward from the top opening of the crushing box 3, thereby greatly improving the safety of the feeding operation.

[0040] The electrical components appearing in the article are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device for control such as a computer, and the existing public power connection technology is not described in detail in the article.

[0041] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
