[0017] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate this utility model.

[0018] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a straw crusher includes: a crushing chamber 20, which is a hollow cylindrical tube with a gradually narrowing bottom opening; a cover plate 21 is provided on the top of the crushing chamber 20; a main motor 22 is fixedly connected to the top of the cover plate 21; and a feed pipe 23 is also fixedly connected to the top of the crushing chamber 20. The feed pipe 23 is cylindrical and its bottom can pass through the top of the cover plate 21. The rotating shaft 24 is cylindrical and can be driven to rotate by the main motor 22. The rotating shaft 24 is rotatably connected to the bottom center of the cover plate 21. A auger 25 is fixedly connected to the arc surface of the rotating shaft 24. The rotating shaft 24 and the auger 25 can be combined to form an auger shape. The cover plate 21 can cover the top opening of the crushing chamber 20. The main motor 22 is electrically connected to the corresponding power supply. This is existing technology and will not be described in detail here.

[0019] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, a refining structure is installed on the wall of the crushing chamber 20 to crush straw. The refining structure includes a refining cylinder 30, a rear plate 31, and a refining auger 32. The refining cylinder 30 is fixedly connected to the bottom of the crushing chamber 20, the rear plate 31 is movably connected to the rear wall of the refining cylinder 30, and the refining auger 32 is rotatably connected to the wall of the rear plate 31. The refining cylinder 30 is connected to the bottom opening of the crushing chamber 20.

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the refining cylinder 30 is a horizontally placed cylindrical tube. The rear plate 31 can cover the opening on the rear wall of the refining cylinder 30. The top of the rear plate 31 can contact the bottom of the grinding chamber 20. The rear plate 31 is semi-circular and can communicate with the bottom opening of the grinding chamber 20 when combined with the refining cylinder 30. The refining auger 32 is located inside the cavity of the refining cylinder 30. The refining structure also includes auxiliary teeth 33, segmented blades 26, and double-cutting blades 27. The auxiliary teeth 33 are fixedly connected inside the cavity of the refining cylinder 30. The segmented blades 26 are symmetrically fixedly connected to the top of the arc surface of the rotating shaft 24, and the double-cutting blades 27 are symmetrically fixedly connected to the bottom of the arc surface of the rotating shaft 24. The auxiliary teeth 33 are semi-circular rings with triangular cross sections. Multiple auxiliary teeth 33 are evenly arranged at the top of the cavity of the refining cylinder 30. The segmented blades 26 are fan-shaped blades and are located above the auger 25. The double-cutting blades 27 are also fan-shaped blades. The symmetrical double-cutting blades 27 are located on the arc surface at the bottom opening of the crushing chamber 20. In practical use, first turn on the power to the main motor 22, then insert the straw to be crushed into the crushing chamber 20 through the top opening of the feed pipe 23. When the main motor 22 is turned on, it will drive the rotating shaft 24 to rotate within the crushing chamber 20. The rotating shaft 24 will drive the segmented blades 26, the auger teeth 25, and the double-cutting blades 27 to rotate synchronously within the crushing chamber 20. The straw inserted into the feed pipe 23 will first come into contact with the rotating segmented blades 26, which will cut the straw into segments. The segmented straw will then be cut and crushed by the auger teeth 25 and fall to the bottom of the crushing chamber 20. The straw enters the cavity formed by the combination of the refining cylinder 30 and the rear plate 31 through the inclined surface. When the straw that has not been completely crushed falls to the bottom inclined surface of the crushing chamber 20, it will be knocked away and cut by the rotating double-cutting blade 27. The rear wall of the rear plate 31 is equipped with a motor for driving the refining auger 32 to rotate. When the crushed straw enters the cavity of the refining cylinder 30, it will come into contact with the rotating refining auger 32. Then, as the refining auger 32 rotates, it will move toward the opening of the front wall of the refining cylinder 30. When the straw comes into contact with the wall of the auxiliary teeth 33, the auxiliary teeth 33 cooperate with the rotating refining auger 32 to further crush the crushed straw, and then it will be discharged from the opening of the refining cylinder 30. In summary, by setting up a refining structure, the crushed straw can be further crushed. The refining structure, through the refining cylinder 30 connected to the bottom of the crushing chamber 20 and the refining auger 32 set in the cavity of the rear plate 31, works with the auxiliary teeth 33 to further crush the crushed straw during discharge, thereby enabling this solution to have stable crushing quality. Furthermore, the double-cutting blade 27 can avoid the problem of straw being discharged before it is completely crushed.

[0021] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the wall of the crushing chamber 20 is provided with a connecting structure, which includes a top fixing plate 40 and a top fixing box 41. The top fixing plate 40 is symmetrically fixed to the top opening of the crushing chamber 20, and the top fixing box 41 is symmetrically fixed to the two side walls of the cover plate 21. The top fixing plate 40 is a semi-circular plate, and the top fixing box 41 is a semi-circular hollow box with an opening at the bottom. The top fixing plate 40 can be inserted into the cavity of the top fixing box 41. The top of the top fixing box 41 and the top fixing plate 40 are provided with threaded holes. The connecting structure also includes a lower fixing plate 42, an alignment post 43, a lower disassembly plate 44, and an alignment groove 45. The lower fixing plate 42 is symmetrically fixed to the top opening of the top opening of the crushing chamber 20, and the top fixing box 41 is symmetrically fixed to the top opening of ... The alignment post 43 is symmetrically fixed to the rear wall opening of the refining cylinder 30. The lower fixing plate 44 is symmetrically fixed to both sides of the front wall of the rear plate 31. The alignment groove 45 is symmetrically opened on the front wall of each lower fixing plate 44. The lower fixing plate 42 and the lower fixing plate 44 are semi-circular plates of the same size. When the refining cylinder 30 and the rear plate 31 are combined, the lower fixing plate 42 and the lower fixing plate 44 can fit together. The alignment post 43 is cylindrical. The alignment groove 45 can adapt to the size of the alignment post 43. The alignment groove 45 and the wall of the lower fixing plate 42 are provided with threaded holes of the same size. In practical use, when the device needs maintenance, all the bolts installed in the threaded holes at the top of the top box 41 are unscrewed, and then the cover plate 21 can be removed from the top of the crushing chamber 20. When the cover plate 21 is removed, it can drive the auger 25, the segmented blade 26 and the double-cutting blade 27 to separate from the crushing chamber 20 at the same time. At this time, the crushing chamber 20 can be cleaned and maintained. After the bolts on the wall of the alignment groove 45 are removed, the rear plate 31 can be separated from the rear wall of the refining cylinder 30. The rear plate 31 can drive the refining auger 32 to separate from the refining cylinder 30 at the same time. In summary, by setting up a connecting structure, the space for straw processing of the device can be disassembled, thereby effectively reducing the workload during cleaning and maintenance of the device.

[0022] Working principle: First, turn on the power to the main motor 22. Then, insert the straw to be crushed into the crushing chamber 20 through the top opening of the feed pipe 23. When the main motor 22 is turned on, it drives the rotating shaft 24 to rotate within the crushing chamber 20. The rotating shaft 24 drives the segmented blades 26, the auger 25, and the double-cutting blades 27 to rotate synchronously within the crushing chamber 20. The straw inserted into the feed pipe 23 first contacts the rotating segmented blades 26, which cut the straw into segments. The segmented straw is then cut and crushed by the auger 25 and falls to the bottom of the crushing chamber 20. The straw then enters the cavity formed by the combination of the refining cylinder 30 and the rear plate 31. When the straw that has not been completely crushed falls to the bottom slope of the crushing chamber 20, it will be knocked away and cut by the rotating double-cutting blade 27. The rear wall of the rear plate 31 is equipped with a motor for driving the refining auger 32 to rotate. When the crushed straw enters the cavity of the refining cylinder 30, it will come into contact with the rotating refining auger 32. Then, as the refining auger 32 rotates, it will move toward the opening of the front wall of the refining cylinder 30. When the straw comes into contact with the wall of the auxiliary teeth 33, the auxiliary teeth 33 cooperate with the rotating refining auger 32 to further crush the crushed straw, and then it will be discharged from the opening of the refining cylinder 30.
