[0002] With the increasing awareness of environmental protection, more and more people begin to realize the importance of environmental protection. In this context, the straw crushing device, as a device that can convert agricultural waste into useful resources, has received more and more attention. Traditional straw crushing devices include large crushers driven by tractors and crushers fixed in place. Large crushers are generally for large areas of farmland and are not suitable for small areas of farmland. Moreover, the crushing and cutting blades are relatively large, which easily makes the crushed straw too long or missed cutting, affecting the decomposition rate and conversion efficiency, and further affecting the growth and yield of crops. For the straw crushing device fixed in place, it can only rely on manual labor to transport the straw back from the field for crushing, which is time-consuming and laborious, and the machine cannot be moved flexibly.

[0027] A handrail 4 is fixedly connected to the top of the vehicle board 1 on the side away from the crushing device 2, and the side of the inclined plate 24 away from the transmission device 3 is fixedly connected to the top of the vehicle board 1 on the side away from the transmission device 3.

[0028] The transmission device 3 includes a motor 31. A middle pulley 33 is fixedly connected to the transmission end of the motor 31. A belt 32 is clamped to the outer wall of the middle pulley 33. One end of the belt 32 away from the motor 31 is clamped to a large pulley 34. A linkage belt is clamped to the outer wall of the large pulley 34. One end of the linkage belt away from the large pulley 34 is clamped to a small pulley 35. The inner wall of the small pulley 35 is fixedly connected to the outer wall of the transmission shaft 25. A pulley shaft 37 is fixedly connected to the middle of the large pulley 34. One end of the pulley shaft 37 close to the housing 22 is fixedly connected to a gear 36. Both ends of the blade connecting shaft 38 penetrate through the housing 22. The blade connecting shafts 38 are distributed on both sides of the pulley shaft 37 and are fixedly connected to gears 36. The number of gears is three and they mesh with each other.

[0029] The bottom of the motor 31 is fixedly connected to the top of the vehicle board 1 through a fixing bracket.

[0030] The universal wheel 5 includes a movable column 51. The outer wall of the movable column 51 is inserted into the inner wall of the bottom of the vehicle board 1. A turntable 52 is fixedly connected to the bottom of the movable column 51. A double-row wheel 53 is rotatably connected to the bottom of the turntable 52.

[0031] Working principle:

[0032] When in use, if it is necessary to process straw into feed, the movable column 51 in the universal wheel 5 can be rotated to make the double-row wheel 53 not in contact with the ground, playing a role in fixing the trolley in place. Then start the motor 31 in the transmission device 3 to make the middle pulley 33 rotate, and drive the large pulley 34 to rotate through the belt 32. The large pulley 34 drives the small pulley 35 to rotate through the linkage belt. Finally, the cutting blade 23 is driven to rotate through the transmission shaft 25. In the large pulley 34, the gear 36 on the pulley shaft 37 will rotate together with the large pulley 34, thereby driving the meshing gears 36 on both sides to rotate. Finally, the blade connecting shaft 38 drives the crushing blade 21 to rotate. Then put the straw into the opening at the top of the housing 22. The baffle 26 will prevent the straw from directly falling through the gap of the crushing blade 21. After being crushed by the crushing blade 21, the straw falls onto the inclined plate 24. Some too long or uncut straw will reach the cutting blade 23 along the inclined plate 24 and be crushed again. Finally, discharging and collection are realized at the fixed connection between the inclined plate 24 and the vehicle board 1. This not only reduces the production cost of the animal husbandry, but also reduces the environmental pollution caused by straw.

[0033] When straw return to the field is needed, push the handrail 4, drive the rotation of the double-row wheels 53 through the turntable 52, and carry the vehicle plate 1 and all the devices connected to the vehicle plate 1 into the field. The machine can be flexibly carried to enable straw crushing in fields of different areas, realizing straw return to the field. If there are long straws, they can be collected and put into the opening at the top of the outer shell 22, and are first crushed by the crushing blades 21 in the crushing device 2, and then the straws are secondarily crushed by the cutting blades 23, so that the straws are fully crushed, which is beneficial to accelerating the decomposition rate and conversion efficiency of the straws, accelerating crop growth and increasing the yield.
