TECHNICAL FIELD

[0001] The application relates to the technical field of pesticide processing, in particular to a grinding equipment for preparing pesticide suspending agent. BACKGROUND

[0002] The production efficiency and quality of pesticide suspending agent as an important pesticide dosage form directly affect the agricultural production effect. The grinding equipment is a key link in the production of pesticide suspending agent.

[0003] At present, the commonly used grinding equipment on the market, such as a horizontal grinding machine, generally comprises a rack, a grinding cylinder horizontally arranged on the rack and having a grinding cavity, a grinding shaft extending into the grinding cylinder, a plurality of grinding discs arranged on the grinding shaft at intervals to grind the material, and a driving motor arranged on the rack to drive the grinding shaft to rotate, wherein the grinding cylinder is provided with a feeding pipe and a discharging pipe, and a space is left between the grinding disc and the inner wall of the grinding cylinder.

[0004] However, in the production process, due to the space left between the grinding disc and the inner wall of the grinding cylinder, and the uniform space between the grinding disc and the inner wall of the grinding cylinder in the prior art, the material will continuously contact the grinding disc at high speed in the grinding cylinder, which causes some unground material to be discharged with the discharging pipe, and thus the dispersibility and stability of the product are poor. Therefore, it is necessary to provide a pesticide suspending agent grinding equipment with good grinding uniformity. CONTENT OF THE INVENTION

[0005] In order to improve the grinding uniformity of the material, the application provides a grinding equipment for preparing pesticide suspending agent.

[0006] The grinding equipment for preparing pesticide suspending agent provided by the application adopts the following technical scheme:

[0007] The grinding equipment for preparing pesticide suspending agent comprises a rack, a grinding cylinder horizontally arranged on the rack and having a grinding cavity, a grinding shaft extending into the grinding cylinder, a plurality of grinding discs arranged on the grinding shaft at intervals to grind the material, and a driving assembly arranged on the rack to drive the grinding shaft to rotate, wherein the two ends of the grinding cylinder are respectively provided with a feeding pipe and a discharging pipe; the outer peripheral wall of the grinding disc and the opposite surfaces of the grinding disc are both provided with grinding protrusions, the density of the grinding protrusions on the plurality of grinding discs gradually increases towards the direction close to the discharging pipe, and the space between the plurality of grinding discs and the inner wall of the grinding cylinder gradually decreases towards the direction close to the discharging pipe.

For some large particles that are adhered to the inner wall of the grinding cylinder by the rotation of the grinding shaft, the large particles are ground on the subsequent grinding discs, thereby achieving a multi-stage grinding effect, improving the grinding uniformity, reducing the overall grinding time, and improving the grinding efficiency. The grinding protrusions are arranged on the opposite surfaces of the grinding disc, some materials collide with the grinding protrusions, and the collision force disperses the materials, which further improves the grinding effect on the materials.

[0014] By adopting the technical scheme, during the grinding process of the material by the grinding disc, the material may be adhered to the inner wall of the grinding cylinder. For this part of the adhered material, the grinding uniformity may be affected. Therefore, the first scraper is arranged by the connecting rod and the grinding shaft. When the driving assembly drives the grinding shaft to rotate, the first scraper scrapes the material adhered to the inner wall of the grinding cylinder, so that the material can be fully ground and mixed, and the number of times of disassembling the grinding cylinder for cleaning is reduced.

[0015] Preferably, the length direction of the first scraper is parallel to the length direction of the grinding cylinder, and the end of the first scraper is arranged in an arc shape away from the discharge pipe.

[0016] By using the above technical scheme, the material adhering to the inner wall of the grinding cylinder between the two grinding discs can be moved to the grinding disc close to the discharge pipe after being scraped by the first scraper and then being scraped by the first scraper along the arc shape of the first scraper.

[0019] Preferably, the outer peripheral wall of the filter cylinder is protrudingly provided with an abutting strip, the length direction of the abutting strip is parallel to the length direction of the filter cylinder, and the second scraper abuts against the abutting strip.

[0020] By using the above technical scheme, the filter cylinder can be subjected to certain mechanical vibration through the abutment between the second scraper and the abutting strip, so as to shake the material and shake the material on the inner wall of the filter cylinder, thereby reducing the influence of the subsequent discharge of the material.

[0021] Preferably, the second scraper abuts against the inner wall of the grinding cylinder.

[0022] By using the above technical scheme, since the filter cylinder is arranged, the material may also adhere to the inner wall of the grinding cylinder located in the filter cylinder. Therefore, the second scraper is abutted to scrape the material.
