Description

Technical Field

[0001] This invention belongs to the field of stubble removal technology, specifically relating to a stubble removal and crushing device. Background Technology

[0002] After harvesting, a large amount of crop stubble remains in the field. To protect the environment, open burning is not allowed. The conventional method is to use stubble destroyers to deal with the stubble. However, existing stubble destroyers only cut the above-ground stubble when in use, and cannot efficiently and synchronously crush the above-ground stubble and underground roots at the same time, which affects the decomposition rate of the stubble. In addition, traditional stubble destroyers involve a large amount of soil movement when crushing the stubble, which causes serious soil moisture loss and easily leads to soil erosion. Summary of the Invention

[0003] The present invention aims to provide a root stubble removal and crushing device to solve the technical problems of existing stubble-killing devices being unable to efficiently and synchronously crush both above-ground stubble and underground roots, and having a large amount of soil removed during root stubble crushing.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A root stubble pulling and crushing device includes an outer casing. A first gearbox, a second gearbox, and a third gearbox are provided on the top of the outer casing. A power input shaft is provided on the first gearbox. Power is transmitted between the first gearbox and the second gearbox through a first transmission shaft. Power is transmitted between the second gearbox and the third gearbox through a second transmission shaft. A third transmission shaft is provided on the third gearbox.

[0006] A stubble side throwing mechanism and a stubble crushing mechanism are installed inside the outer casing, and the third drive shaft is connected to the stubble crushing mechanism.

[0007] The stubble side-throwing mechanism includes a frame groove, a first mounting block, and a second mounting block. The frame groove is located at the top of the outer casing. A long slider is provided in the frame groove and can move within the frame groove. The top of the outer casing has three rectangular notches, and the bottom of the frame groove has a long strip notch. Three sets of mechanical claws are fixed to the bottom of the long slider. The long strip notch and the three rectangular notches are used to allow the upper ends of the three sets of mechanical claws to pass through and be fixed to the bottom of the long slider. The three sets of mechanical claws are located inside the outer casing.

[0008] A connecting rod is fixed between the three sets of mechanical claws. The end of the connecting rod is provided with a long circular ring, which is set in the vertical direction. The first mounting block and the second mounting block are both fixed to the inner wall of the outer casing. A horizontal rocker arm is rotatably mounted on the second mounting block. The end of the horizontal rocker arm is located inside the long circular ring. A vertical rocker arm is rotatably mounted on the first mounting block. The end of the vertical rocker arm is hinged to the end of the frame groove. The second drive shaft drives the vertical rocker arm to rotate through the first belt. The second drive shaft drives the horizontal rocker arm to rotate through the second belt.

[0009] Furthermore, the stubble crushing mechanism includes a cutter shaft, which is rotatably mounted inside the outer casing. Three cutter sets are provided on the cutter shaft, and a cutter shaft gear is installed at the end of the cutter shaft. A first gear shaft, a second gear shaft, and a median gear shaft are rotatably mounted on the outer casing. A first sector gear is installed on the first gear shaft, a second sector gear is installed on the second gear shaft, and a median gear is installed on the median gear shaft. The cutter shaft gear meshes with the first sector gear and the median gear, and the second sector gear meshes with the median gear.

[0010] The third drive shaft drives the first gear shaft and the second gear shaft to rotate via the third belt and the fourth belt, respectively.

[0011] Compared with the prior art, the beneficial effects of the present invention are: the present invention uses a mechanical claw to grab and pull out the stubble, then the stubble side-throwing mechanism throws the stubble to the side, and the stubble crushing mechanism crushes the stubble through a forward and reverse blade shaft, which reduces the amount of soil disturbed, reduces soil moisture loss and soil erosion.

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. 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 scope of protection of the present invention.

[0019] The present invention will be further described in detail below with reference to the embodiments.

[0020] like Figure 1-5 As shown, a specific embodiment of the root stubble extraction and crushing device provided by the present invention is as follows:

[0021] A root stubble pulling and crushing device includes an outer casing 1. The top of the outer casing 1 is provided with a first gearbox 2, a second gearbox 3 and a third gearbox 4. The first gearbox 2 is provided with a power input shaft 5. The first gearbox 2 and the second gearbox 3 transmit power through a first transmission shaft 6. The second gearbox 3 and the third gearbox 4 transmit power through a second transmission shaft 7. The third gearbox 4 is provided with a third transmission shaft 8.

[0022] A stubble side throwing mechanism and a stubble crushing mechanism are installed inside the outer casing 1, and the third drive shaft 8 is connected to the stubble crushing mechanism.

[0023] The root stubble side-throwing mechanism includes a frame groove 9, a first mounting block 10, and a second mounting block 11. The frame groove 9 is located at the top of the outer casing 1. A long slider 12 is provided inside the frame groove 9 and can move within the frame groove 9. The top of the outer casing 1 is provided with three rectangular notches 13, and the bottom of the frame groove 9 is provided with a long strip notch. Three sets of mechanical claws 14 are fixed to the bottom of the long slider 12. The long strip notch and the three rectangular notches 13 are used to allow the upper ends of the three sets of mechanical claws 14 to pass through and be fixed to the bottom of the long slider 12. The three sets of mechanical claws 14 are located inside the outer casing 1.

[0024] A connecting rod 15 is fixed between the three sets of mechanical claws 14. The end of the connecting rod 15 is provided with a long circular ring 16, which is arranged in the vertical direction. The first mounting block 10 and the second mounting block 11 are both fixed to the inner wall of the outer casing 1. A horizontal rocker arm 17 is rotatably mounted on the second mounting block 11, and the end of the horizontal rocker arm 17 is located inside the long circular ring 16. A vertical rocker arm 18 is rotatably mounted on the first mounting block 10, and the end of the vertical rocker arm 18 is hinged to the end of the frame groove 9. The second drive shaft 7 drives the vertical rocker arm 18 to rotate through the first belt 20, and the second drive shaft 7 drives the horizontal rocker arm 17 to rotate through the second belt 19.

[0025] Furthermore, the stubble crushing mechanism includes a cutter shaft 21, which is rotatably mounted inside the outer casing 1. Three cutter groups 22 are provided on the cutter shaft 21. A cutter shaft gear 23 is installed at the end of the cutter shaft 21. A first gear shaft 24, a second gear shaft 25, and a median gear shaft 26 are rotatably mounted on the outer casing 1. A first sector gear 27 is installed on the first gear shaft 24, a second sector gear 28 is installed on the second gear shaft 25, and a median gear 29 is installed on the median gear shaft 26. The cutter shaft gear 23 meshes with the first sector gear 27 and the median gear 29, and the second sector gear 28 meshes with the median gear 29.

[0026] The third drive shaft 8 drives the first gear shaft 24 and the second gear shaft 25 to rotate via the third belt 30 and the fourth belt 31, respectively.

[0027] The specific stubble removal operation is as follows: The power input shaft 5 drives the first gearbox 2, the first gearbox 2 drives the second gearbox 3 through the first transmission shaft 6, and the second gearbox 3 drives the third gearbox 4 through the second transmission shaft 7; the second transmission shaft 7 drives the vertical rocker arm 18 to rotate through the first belt 20. During the rotation, the vertical rocker arm 18 pulls the frame groove 9 to move vertically; at the same time, the second transmission shaft 7 drives the horizontal rocker arm 17 to rotate through the second belt 19. The horizontal rocker arm 17 pulls the connecting rod 15 through the long ring 16, so that the connecting rod 15 reciprocates horizontally. The connecting rod 15 drives the three sets of mechanical claws 14 to move horizontally. Driven by the frame groove 9 and the connecting rod 15, the three sets of mechanical claws 14 perform a compound movement in the horizontal and vertical directions. When moving downward, the mechanical claws 14 grab the stubble. When moving horizontally, they throw the stubble out laterally. The mechanical claws 14 are existing conventional technology and are used in various technical fields. Their specific structure and working principle will not be described in detail here.

[0028] The third drive shaft 8 drives the first gear shaft 24 and the second gear shaft 25 to rotate via the third belt 30 and the fourth belt 31. The first sector gear 27 and the second sector gear 28 on the first gear shaft 24 and the second gear shaft 25 rotate accordingly. When the first sector gear 27 meshes with the cutter shaft gear 23, the second sector gear 28 is disengaged from the intermediate gear 29, meaning the second sector gear 28 cannot transmit power to the intermediate gear 29. The first sector gear 27 drives the cutter shaft gear 23 to rotate. Assuming this… When the cutter shaft gear 23 is rotating forward, the three cutter groups 22 together cut the remaining roots and stubble in the soil. As the first sector gear 27 rotates, the first sector gear 27 disengages from the cutter shaft gear 23. At this time, the second sector gear 28 begins to mesh with the intermediate gear 29. The intermediate gear 29 drives the cutter shaft gear 23 to rotate. Since the first sector gear 27 and the second sector gear 28 rotate in the same direction, the cutter shaft gear 23 begins to rotate in the opposite direction, the cutter shaft 21 begins to rotate in reverse, and the cutter group 22 rotates in reverse to reset.
