[0028] The following combines the accompanying drawings to make a detailed description of some implementation modes of the present utility model. Without conflict, the following embodiments and the features in the embodiments can be combined with each other.

[0029] Embodiment 1

[0030] Please refer to Figures 1-6 , the embodiment of the present utility model provides an organic fertilizer granulation device, including a bottom frame 1 and a granulation box 2 located on the upper side. A first extrusion roller 3 and a second extrusion roller 4 are symmetrically and rotatably arranged in the granulation box 2. A plurality of grooves 5 are formed on the surface of the first extrusion roller 3, and a plurality of protrusions 6 are arranged on the surface of the second extrusion roller 4. When the first extrusion roller 3 and the second extrusion roller 4 rotate relative to each other, the cow dung entering can be extruded to form particles.

[0031] In addition, two guide plates 17 are symmetrically arranged on the upper side of the granulation box 2. The guide plates 17 guide the cow dung into the space between the first extrusion roller 3 and the second extrusion roller 4, reducing waste of resources.

[0032] At the same time, a pair of dispersing rollers 21 are rotatably arranged on the upper side of the bottom frame 1. The rotating shafts of the two dispersing rollers 21 are respectively connected to two rotating gears 22. The two rotating gears 22 are meshed with each other. One of the rotating gears 22 is driven by a motor. When the two rotating gears 22 rotate, the two dispersing rollers 21 rotate relative to each other to disperse the particles falling from top to bottom, reducing the situation where the particles are connected together. At the same time, a feeding plate 23 is arranged inside the bottom frame 1, and the particles are exported from the bottom frame 1 through the feeding plate 23.

[0033] In order to clean the first extrusion roller 3 and the second extrusion roller 4, a pair of brushes 19 are rotatably arranged on the lower side of the granulation box 2. The pair of brushes 19 are respectively attached to the surfaces of the first extrusion roller 3 and the second extrusion roller 4. The pair of brushes 19 are connected by a transmission part 20. The transmission part 20 is two belt pulleys connected to the rotating shafts of the brushes 19 and a belt sleeved on the two belt pulleys. The transmission part 20 is driven by a motor. When the brushes 19 rotate, the surfaces of the first extrusion roller 3 and the second extrusion roller 4 during granulation are cleaned, reducing the adhesion of cow dung.

[0034] Further, adjustment holes 18 are formed in the granulation box 2 at both ends of the second extrusion roller 4. An adjustment mechanism is installed in the adjustment holes 18. The adjustment mechanism includes a pair of adjustment frames 9 arranged on one side of the two adjustment holes 18. A moving block 10 is slidably arranged in each of the pair of adjustment frames 9. The second extrusion roller 4 is rotatably arranged between the two moving blocks 10. The sliding of the moving block 10 in the adjustment frame 9 can move the second extrusion roller 4 away from the first extrusion roller 3.

[0035] Since one side of the moving block 10 is rotatably connected to the screw 13, and one end of the screw 13 penetrates through the side wall of the adjustment frame 9 and is threadedly connected to the adjustment frame 9, rotating the screw 13 can make the moving block 10 move more labor - saving and stably.

[0036] Sliders 12 are arranged on both the upper and lower sides of the moving block 10. The two sliders 12 slide in the chutes 11 formed on the upper and lower sides of the adjustment frame 9 respectively, which improves the stability of the moving block 10 during movement.

[0037] And one end of each of the first extrusion roller 3 and the second extrusion roller 4 is connected to two gear disks 7 respectively. The gear disks 7 are located on one side of the moving block 10. Both of the two gear disks 7 are meshed with a long gear 8 rotatably arranged on one side of the granulation box 2. The long gear 8 is driven by a motor. Therefore, when the long gear 8 rotates, it meshes with the two gear disks 7, making the two gear disks 7 drive the first extrusion roller 3 and the second extrusion roller 4 to rotate in opposite directions to achieve granulation. At the same time, due to the certain length of the long gear 8, after the second extrusion roller 4 moves, it does not affect the meshing with the gear disk 7.

[0038] Furthermore, a cleaning member is installed on one side inside the granulation box 2. The cleaning member includes a cylinder 14 installed on one side of the granulation box 2. The piston end of the cylinder 14 is connected to a connecting rod 15. Two annular brushes 16 are arranged on the lower side of the connecting rod 15. One of the annular brushes 16 corresponds to the position of the first extrusion roller 3, and the other annular brush 16 corresponds to the position of the second extrusion roller 4 after movement. Therefore, after the second extrusion roller 4 moves to one side of the adjustment hole 18 and corresponds to the position of the annular brush 16, there is a certain distance between the first extrusion roller 3 and the second extrusion roller 4 at this time. After the cylinder 14 drives the two annular brushes 16 to be sleeved on the first extrusion roller 3 and the second extrusion roller 4, they can reciprocally clean the two rollers.

[0039] Embodiment Two

[0040] Due to the certain length of the long gear 8, after the second extrusion roller 4 moves, the gear disk 7 at one end of the second extrusion roller 4 can continue to mesh with the long gear 8, thus satisfying the rotation of the second extrusion roller 4. Therefore, by adjusting the second extrusion roller 4, the distance between the first extrusion roller 3 and the second extrusion roller 4 can be adjusted, thereby realizing the adjustment of the granule size of the granulation. In addition, when the slider 12 is connected to the granulation box 2 by bolts, the stability of the second extrusion roller 4 during granulation can be improved.

[0041] In summary, the working principle of an organic fertilizer granulation device according to an embodiment of the present utility model is as follows: The brush 19 is driven by the transmission member 20 to clean the first extrusion roller 3 and the second extrusion roller 4 that are rotating for granulation, reducing the occurrence of cow dung adhesion during the granulation process. When not granulating, the bolt on the slider 12 can be removed, and by rotating the screw rod 13, the moving block 10 drives the second extrusion roller 4 to move to one side, increasing the distance between the first extrusion roller 3 and the second extrusion roller 4. The air cylinder 14 drives the two annular brushes 16 to be sleeved on the first extrusion roller 3 and the second extrusion roller 4 to reciprocally clean them.

[0042] The above is only the preferred embodiment of the present utility model and is not used to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
