[0024] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0025] like Figure 1-Figure 4 As shown, this embodiment discloses a fertilizer clumping crushing device, including a shell 1, a roller crushing mechanism 2 is arranged inside the shell 1, a horizontally arranged rotating shaft 3 is rotatably connected to the lower side of the roller crushing mechanism 2, and the rotating shaft 3 is connected to the roller crushing mechanism 2 through a transmission component 4; two fixed rod groups are provided, and the two fixed rod groups are correspondingly arranged on the inner walls on both sides of the shell 1, and each fixed rod group includes a plurality of fixed rods 5 evenly spaced along the horizontal direction; multiple movable rod groups are provided, and the multiple movable rod groups are spaced along the circumference of the rotating shaft 3, and each movable rod group includes a plurality of movable rods 6 evenly spaced along the horizontal direction, and each movable rod 6 corresponds to the interval between two adjacent fixed rods 5.

[0026] In this embodiment, a hopper 7 is fixed to the top of the housing 1, and a discharge pipe 8 is fixedly connected to the bottom. Multiple legs 9 are fixedly connected to the bottom of the housing 1. A rotating shaft 3 is located midway between the two sets of fixed rods. A movable rod 6 is fixedly connected to the rotating shaft 3, and a fixed rod 5 is fixedly connected to the inner wall of the housing 1. Gaps are provided between the fixed rod 5 and the rotating shaft 3, between the movable rod 6 and the inner wall of the housing 1, and between the movable rod 6 and the fixed rod 5 for the passage of fertilizer particles.

[0027] With this solution, the provided double-roller crushing mechanism 2 can be used to preliminarily crush the agglomerated fertilizer, so that large pieces of fertilizer are broken into a mixture of small pieces and fertilizer particles. Through the provided transmission component 1 4, when the double-roller crushing mechanism 2 is running, it can drive the rotating shaft 3 and the movable rod 6 to rotate, and the movable rod 6 passes through the gap between two adjacent fixed rods 5, so that the small pieces of fertilizer can be crushed again. Through the coordinated use of the above-mentioned structures, the effect of crushing large pieces of agglomerated fertilizer into uniform fertilizer particles can be achieved at one time, thereby improving convenience.

[0028] In a further optimized solution, the paired-roll crushing mechanism 2 comprises two crushing rollers 21 that rotate relative to each other and are arranged horizontally and parallel with each other. Multiple groups of crushing teeth are evenly spaced along the axis of the crushing rollers 21. Each group of crushing teeth includes multiple crushing teeth 22 evenly distributed along the circumference of the crushing roller 21. The multiple groups of crushing teeth on the two crushing rollers 21 are staggered. In this embodiment, the crushing teeth 22 are fixedly connected to the crushing rollers 21 by welding. When the two crushing rollers 21 rotate relative to each other, they can break large lumps of fertilizer into a mixture of small pieces and fertilizer particles.

[0029] To further optimize the solution, a rotating drive component 24 is connected to the outer wall of the shell 1 through a support seat 23, and the output shaft of the rotating drive component 24 is dynamically connected to the end of one of the crushing rollers 21; a transmission component 25 is provided on the two crushing rollers 21, and the rotating drive component 24 drives the two crushing rollers 21 to rotate relative to each other through the transmission component 25.

[0030] In this embodiment, the rotary drive component 24 is configured as a servo motor, and the fixed end of the rotary drive component 24 is fixed to the support base 23. The rotary drive component 24 drives one of the crushing rollers 21 to rotate, and under the action of the second transmission assembly 25, the two crushing rollers 21 can be driven to rotate relative to each other.

[0031] In a further optimized solution, the transmission assembly 1 4 includes two synchronous pulleys 41, which are respectively fixedly mounted on one of the crushing rollers 21 and the rotating shaft 3. A synchronous belt 42 is mounted on each of the synchronous pulleys 41. The synchronous pulleys 41 and the synchronous belt 42 enable the rotating shaft 3 to rotate when the crushing roller 21 rotates.

[0032] In a further optimized solution, the second transmission assembly 25 includes two meshing gears 251, each of which is fixedly mounted on a corresponding crushing roller 21. The two gears 251 ensure that when the rotary drive component 24 drives one crushing roller 21 to rotate, the other crushing roller 21 can also rotate relative to the other crushing roller 21.

[0033] The working process of the utility model is as follows: large lumps of fertilizer are fed into the roller crushing mechanism 2 in the shell 1 through the feeding hopper 7. After being crushed by the roller crushing mechanism 2, a mixture of small pieces and fertilizer particles is formed. The mixture falls to the fixed rod 5. Through the rotation of the rotating shaft 3 and the movable rod 6, the small pieces of fertilizer can be further crushed; the crushed fertilizer particles can fall to the bottom of the shell 1 through the gap and can be discharged through the discharge pipe 8.

[0034] The embodiments described above are merely preferred embodiments of the present invention and are not intended to limit the scope of the present invention. Without departing from the spirit of the present invention, various modifications and improvements to the technical solutions of the present invention made by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present invention.
