[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The organic fertilizer solid raw material crushing and screening equipment disclosed in the present application, after the solid raw material is put into the crushing bin, the driving motor drives the upper crushing disk to rotate circumferentially, and the stirring column installed on the upper crushing disk stirs the raw material to make it fall between the upper crushing disk and the lower crushing disk, the lower crushing disk cannot rotate circumferentially, and the relative rotation between the upper crushing disk and the lower crushing disk can crush the raw material, and the crushed raw material falls into the filtering bin and is discharged from the discharge port; large particles of raw material slide into the transfer box, and are lifted to the upper part of the crushing bin by the spiral lifting component and crushed again, thereby realizing the automated and efficient crushing operation of solid raw materials.

[0018] 2. When the present invention is used to crush hard solid raw materials, the crushing is not complete. In order to solve this technical problem, the present invention starts from the following three aspects:

[0019] 1. The upper surface of the upper crushing disk is provided with a first inclined portion inclined from outside to inside, and the lower surface of the upper crushing disk is provided with a second lower inclined portion and a third inclined portion inclined from right inside to outside, the angle between the second inclined portion and the horizontal plane is greater than the angle between the third inclined portion and the horizontal plane, and the upper surface of the lower crushing disk is provided with a fourth inclined portion, which matches the third inclined portion. This structural design can form an angle between the second inclined surface and the fourth inclined surface, and when the upper crushing disk rotates circumferentially, the raw material can be primarily crushed;

[0020] 2. After the primary crushed raw materials enter the third inclined part and the fourth inclined part, the gap between the two becomes smaller, and the raw materials can be crushed again, thereby gradually crushing the solid raw materials;

[0021] 3. The fourth inclined portion is provided with a plurality of saw teeth in the opposite direction of the rotation of the upper crushing disk, which can increase the rolling crushing angle of the raw material and further optimize the crushing effect.

[0022] 3. It should be pointed out that for raw materials that cannot be completely crushed in one go, the spiral lifting assembly arranged in the present invention can be crushed multiple times. During this process, the distance between the upper crushing plate and the lower crushing plate is adjustable. Specifically, multiple mounting seats are fixed on the outside of the raw material circulation lifting cylinder, and a support frame and a spring are set on the lower surface of the lower crushing plate, so that the lower crushing plate mounted on the outside of the raw material circulation lifting cylinder can move up and down, thereby self-adjusting the gap between the upper crushing plate and the lower crushing plate to facilitate the passage of such raw materials.

[0023] 4. The present invention arranges a vibration motor and a U-shaped frame on the equipment frame. The upper end of the U-shaped vibration frame is connected to the second horizontal plates in the two opposite support assemblies. The operation of the vibration motor can drive the filter bin to vibrate, thereby accelerating the filtering of the crushed raw materials; the guide column in the support assembly guides the vibration direction of the filter bin.

[0024] 5. A plurality of stirring columns are arranged on the first inclined portion of the upper crushing disk. The stirring columns are arranged in two layers inside and outside. Two adjacent stirring columns on the same layer are arranged in a staggered manner. The raw materials at different positions can be lifted and turned during the rotation of the upper crushing disk, thereby improving the raw material dropping effect.
