Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0028] Embodiment 1
[0029] As attached Figure 1 , Attachment Figure 3 and attached Figure 4 As shown, a rolling fertilizer uniform crushing mechanism comprises a box body 1, a feeding port 3 is provided at the upper part of one side wall of the box body 1, a discharge port 5 is installed at the lower part of the other side wall of the box body 1, two groups of strip through holes 13 are respectively provided on the two side walls of the box body 1 close to the two groups of positioning plates 10, two groups of crushing rollers 15 are arranged inside the box body 1, a rotating shaft 16 is installed at the axis center of one end of the crushing roller 15, the other end of the rotating shaft 16 passes through the strip through hole 13 and is connected to a motor 18, a rectangular plate 17 connected to the motor 18 is rotatably installed on the outer side of the rotating shaft 16, and the rectangular plate 17 is connected to the motor 18. 17 is located outside the box body 1 and is installed with multiple groups of plug rods 19 on one side close to the box body 1. A threaded shaft 20 is rotatably installed at the axis of the other end of the crushing roller 15. A rectangular plate 21 is installed on the outside of the threaded shaft 20. The rectangular plate 21 is located inside the box body 1 and is installed with multiple groups of plug rods 22 on one side close to the side wall of the box body 1. Multiple groups of plug holes 14 for inserting the plug rods 19 and 22 are equidistantly arranged on the side wall of the box body 1 and located on opposite sides of the strip through hole 13. The other end of the threaded shaft 20 passes through the strip through hole 13 and is sleeved with a nut 23 on the outside.
[0030] A crushing bottom plate 7 is provided at the bottom of the box body 1, and positioning plates 10 are respectively installed at the opposite side edges of the crushing bottom plate 7, and multiple groups of springs 12 are respectively installed on the side where two groups of positioning plates 10 are close to each other, and a moving plate 11 is installed between the other ends of the multiple groups of springs 12 installed on the same group of positioning plates 10.
[0031] Through the above structure, the nut 23 is moved on the threaded shaft 20 to the side away from the box body 1, and the crushing roller 15 is moved horizontally inside the box body 1, so that the multiple groups of plug rods 1 19 and multiple groups of plug rods 22 are pulled out from the insertion holes 14. At this time, the crushing roller 15 can be moved up and down, so that the rotating shaft 16 and the threaded shaft 20 are moved up and down inside the strip through hole 13 respectively. When the crushing roller 15 and the crushing bottom plate 7 are adjusted to a suitable spacing, the crushing roller 15 is moved horizontally to pull out the multiple groups of plug rods 1 19 and multiple groups of plug rods 22. 22 are respectively inserted into the corresponding jacks 14, and then the nut 23 is moved on the threaded shaft 20 to the side close to the box body 1, so that the rectangular plate 1 17 and the rectangular plate 2 21 are respectively close to the box body 1, ensuring the stability of the crushing roller 15. When the crushing roller 15 moves horizontally, the crushing roller 15 pushes the moving plate 11 to move, and the moving plate 11 presses the multiple sets of springs 12 when moving. When the crushing roller 15 is positioned and installed, the moving plate 11 is pushed to the original position by the resilience of the multiple sets of springs 12. The specific structure is as follows:
[0032] Combined with Figure 2 and attached Figure 3As shown, a through hole 9 is provided at the lower part of a side wall of the box body 1 with a feed port 3 for the crushing bottom plate 7 to pass through. A mounting plate 8 is installed on one side of the crushing bottom plate 7 and passes through the through hole 9. The mounting plate 8 is connected to the side wall of the box body 1 with bolts.
[0033] Through the above structure, the crushing bottom plate 7 can be easily replaced through the through hole 9, and the mounting plate 8 can be connected to the side wall of the box body 1 to ensure the stability of the crushing bottom plate 7.
[0034] Combined with Figure 1 and attached Figure 2 As shown, a control switch 24 connected to two sets of motors 18 is installed on the outer wall of one side of the box body 1, a feed chute 4 is installed on the outer wall of one side of the box body 1 and located outside the feed port 3, a discharge inclined plate 6 is installed on the outer wall of the other side of the box body 1 and located below the discharge port 5, and a cover plate 2 is installed on the upper side of the box body 1.
[0035] Through the above structure, the start and stop and speed of the two groups of motors 18 are controlled respectively by the control switch 24, and the fertilizer material is conveniently fed into the feed port 3 through the feed trough 4. The fertilizer material discharged from the discharge port 5 can be kept away from the position of the box body 1 through the discharge inclined plate 6, so as to facilitate the collection of the fertilizer material at a later time.
[0036] Embodiment 2
[0037] Based on Example 1, please refer to the attached Figure 3 and attached Figure 4 The two groups of crushing rollers 15 are respectively provided with extrusion strips on the outside. The width and spacing of the extrusion strips on the outside of one group of crushing rollers 15 close to the feed port 3 are greater than the width and spacing of the extrusion strips on the outside of the other group of crushing rollers 15. The upper side of the crushing bottom plate 7 is provided with extrusion strips that are the same as the extrusion strips on the outside of the crushing rollers 15.
[0038] Through the above structure of the second embodiment, extrusion bars are arranged on the outer side of the crushing roller 15 and on the upper side of the crushing bottom plate 7, which has a better crushing effect on the fertilizer material. The width and spacing of the extrusion bars on the outer side of a group of crushing rollers 15 close to the feed inlet 3 are larger, and the fertilizer material is initially crushed to make the particles more uniform, and then finely crushed by another group of crushing rollers 15, so that the crushing quality of the fertilizer material is better.
[0039] The specific usage is as follows:
[0040] The fertilizer material is sent to the upper side of the crushing bottom plate 7 through the feed inlet 3. The upper side of the crushing bottom plate 7 is an inclined structure, so that the fertilizer material can slide toward the discharge port 5. The two groups of motors 18 are started by the control switch 24, and the speed of the motor 18 is set. The motor 18 drives the rotating shaft 16 to rotate, and the rotating shaft 16 drives the crushing roller 15 to rotate. The fertilizer material is crushed by the cooperation of the crushing roller 15 and the crushing bottom plate 7. When the fertilizer material is crushed, the lower part of the crushing roller 15 is located between the two groups of movable plates 11 and the two ends are respectively close to the movable plates 11. The fertilizer material is restricted by the movable plate 11 to prevent the fertilizer material from leaking from both sides of the crushing roller 15 and affecting the quality of the crushed fertilizer. The fertilizer material crushed by the two groups of crushing rollers 15 continues to slide from the upper side of the crushing bottom plate 7 and is discharged from the box 1 through the discharge port 5.
