[0022] Reference Figure 1-Figure 3 A fertilizer ultrafine pulverizing device comprises an upper cylinder 1 and a lower cylinder 2 with openings at both ends. The upper cylinder 1 and the lower cylinder 2 are both funnel-shaped to prevent the crushed fertilizer from falling out of the collection range due to dispersion. The upper cylinder 1 is located above the lower cylinder 2. A support seat 3 is welded to the outside of the upper cylinder 1 and the lower cylinder 2. A gantry bracket 4 is welded to the top of the upper cylinder 1. A first drive motor 5 is fixedly installed on the upper end of the gantry bracket 4. The upper cylinder 1 is provided with a grinding mechanism for crushing the fertilizer through the first drive motor 5. A support platform 15 is fixedly connected to the outside of the lower cylinder 2. The support platform 15 is fixedly connected to the second drive motor 16. The lower cylinder 2 is provided with a sorting mechanism for screening the crushed fertilizer through the second drive motor 16. After the fertilizer passes through the grinding mechanism, it naturally falls to the sorting mechanism for screening. Fertilizer that is not fully crushed will be put back into the grinding mechanism for crushing.

[0023] The grinding mechanism includes a rolling disc 7 opened in the upper cylinder 1, and two crushing rollers 6 matching the rolling disc 7 are fixedly connected to the output end of the first drive motor 5. The crushing rollers 6, the rolling disc 7 and the rotating fan blades 8 are all concentrically distributed in the upper cylinder 1, and the upper cylinder 1 forms two funnel cavities corresponding to the crushing rollers 6 through the rolling disc 7. The funnel cavities and the rolling disc 7 are correspondingly provided with movably engaged threaded grooves. The bottom end of the output shaft of the first drive motor 5 is fixedly connected with a rotating fan blade 8, and the rotating fan blade 8 is movably mounted in the upper cylinder 1. The ground fertilizer will clump, and the rotating fan blade 8 is rotated and hit to break up the fertilizer blocks, making the subsequent screening effect more obvious.

[0024] The sorting mechanism includes a support frame 9 welded in the lower cylinder 2, a filter plate 10 is slidably connected to the support frame 9, and a buffer column 11 is welded to the left end of the filter plate 10, a buffer table 12 is welded in the lower cylinder 2 and contacts with the buffer column 11, a strong spring 26 is fixedly installed in the buffer table 12 to provide buffering protection for the filter plate 10, a left through groove 13 and a right through groove 14 are provided at the left and right ends of the lower cylinder 2, the left through groove 13 is provided with a telescopic tooling for pulling and shaking the filter plate 10, and a limiting tooling for limiting the filter plate 10 is provided in the right through groove 14.

[0025] The telescopic tooling includes a driving bar 17 fixedly connected to the output end of the second driving motor 16, the driving bar 17 is slidably connected to a transmission bar 18 with a first through groove 27, the transmission bar 18 is rotatably connected to a driven bar 19, the driven bar 19 is movably connected to a slide column 20, a guide slide groove 21 for pulling the slide column 20 is provided on the support platform 15, and a second through groove 28 is provided at the angle of the support platform 15, so as to provide space for the driving bar 17, the transmission bar 18 and the driven bar 19 to rotate and prevent collision with the support platform 15 and damage to components, and the slide column 20 is connected to the filter plate 10 by threads.

[0026] The limiting tooling includes a rotating handle 23 rotatably mounted on the lower cylinder 2 through a damping bearing, and a rotating gear 22 is fixedly mounted on the rotating handle 23. By setting the damping bearing, the rotating gear 22 is prevented from being deflected when the equipment shakes during operation, thereby failing to achieve the limiting effect. A supporting slide 24 is welded on the lower cylinder 2, and a limiting slide groove 29 is provided at the upper end of the supporting slide 24, and two transmission racks 25 meshing with the rotating gear 22 are slidably mounted in the limiting slide groove 29.

[0027] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be repeated.

[0028] The functional principle of the utility model can be explained through the following operation modes:

[0029] Start the first drive motor 5, pour the fertilizer from the opening of the upper cylinder 1, and the fertilizer enters the matching gap between the crushing roller 6 and the rolling plate 7, and the fertilizer is gradually crushed. The crushed fertilizer is fully scattered by the rotating blades 8 and then falls onto the filter plate 10;

[0030] The second driving motor 16 is turned on, the driving bar 17 rotates to drive the transmission bar 18 to rotate in a circular motion, and the transmission bar 18 drives the driven bar 19 to make repeated periodic motions, and then the slide column 20 slides back and forth in the guide slide groove 21, and cooperates with the limit tooling to slide back and forth on the support frame 9 to achieve the purpose of screening. The crushed fertilizers that meet the standards naturally fall into the collection box placed at the bottom opening of the lower cylinder 2, and the rest remain on the filter plate 10;

[0031] The rotating handle 23 is rotated clockwise, and the rotating gear 22 connected thereto is meshed to drive the transmission rack 25 to open, thereby releasing the threaded connection between the slide column 20 and the filter plate 10, and the filter plate 10 can be taken out, and the fertilizer in the filter plate 10 is poured back into the opening of the upper cylinder 1 for re-crushing.

[0032] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
