Technical Field

[0001] The utility model belongs to the technical field of pesticide processing, and in particular relates to a grinding device used for pesticide processing. Background Art

[0002] Pesticides refer to chemical agents used in agriculture to prevent and control pests and diseases and regulate plant growth. They are widely used in agricultural, forestry and animal husbandry production, environmental and household hygiene pest control and epidemic prevention, industrial product mildew and moth prevention, etc. During the processing of pesticides, they need to be ground into powder through a powder grinding device.

[0003] Most of the existing grinding devices for pesticide processing first put the drug into the grinding tank, and then move the grinding roller into the grinding tank for rotation and grinding. However, during this grinding process, when it is necessary to understand the grinding progress, the grinding roller must be moved out to view the drug grinding progress, and it is impossible to continue adding drugs for grinding during the drug powder grinding process. The grinding roller must be taken out before the drug powder can be put in and out. The operation is relatively complicated and the work efficiency is low. For this reason, we propose a grinding device for pesticide processing. Utility Model Content

The gear 204 drives the hollow rotating rod 3 to rotate through the arc-shaped toothed plate 4 on the left side, and then when the upper intermittent gear 203 is no longer meshed with the first transmission spur gear 204, the lower intermittent gear 203 is meshed with the second transmission spur gear 205, thereby driving the second transmission spur gear 205 to rotate, and the second transmission spur gear 205 drives the third transmission spur gear 206 to rotate, and the third transmission spur gear 206 drives the hollow rotating rod 3 to rotate through the arc-shaped toothed plate 4 on the right side, and at this time, the rotation direction of the hollow rotating rod 3 is opposite to that before. A second rotating shaft 5 is provided at the upper end of the hollow rotating rod 3, and a lower grinding roller 6 is provided at the upper end of the second rotating shaft 5. When the hollow rotating rod 3 rotates back and forth, it can drive the second rotating shaft 5 and the lower grinding roller 6 to rotate back and forth, so that the lower grinding roller 6 can smoothly grind the medicine, and a feeding groove 7 is provided inside the lower grinding roller 6. The setting of the feeding groove 7 can allow the ground qualified medicine powder to fall into the lower end of the grinding box 1 through the feeding groove 7, which is convenient for subsequent collection and use.

[0022] In this embodiment, preferably, a lifting cylinder 10 is provided in the middle at the rear end of the upper surface of the grinding box 1. A connecting rod 11 is provided at the upper end of the lifting cylinder 10. A upper grinding roller 9 is provided on the lower surface at the front end of the connecting rod 11, and the upper grinding roller 9 is arranged directly above the lower grinding roller 6.

A feeding pipe 13 is provided in the middle at the upper end of the upper grinding roller 9, and the feeding pipe 13 is curved. The setting of the curved feeding pipe 13 can smoothly feed the medicine into the upper grinding roller 9 and the lower grinding roller 6, while avoiding the waste of medicine powder caused by some medicine powder splashing out through the feeding pipe 13 during the grinding process of the medicine. A feeding port 12 is provided at the upper end of the feeding pipe 13. The setting of the feeding port 12 facilitates the staff to add the medicine into the grinding box 1 through the feeding port 12 for grinding work.

An outlet 14 is opened at the lower end of the left side wall of the grinding box 1, and a sealing door plate is hinged inside the outlet 14 through a hinge shaft. The setting of the outlet 14 and the sealing door plate can, after the medicine powder is ground, open the sealing door plate to centrally collect the ground medicine powder at the outlet 14.

[0024] Working principle and usage process of the utility model: When grinding drugs during pesticide processing, first, the drugs are fed into the inner part of the feeding pipe 13 through the feeding port 12. Then, the drugs will fall between the upper grinding roller 9 and the lower grinding roller 6. Next, the servo motor 201 is started. The servo motor 201 drives the first rotating shaft 202 and the two intermittent gears 203 to rotate. Subsequently, through the arranged first transmission spur gear 204, second transmission spur gear 205 and third transmission spur gear 206, the hollow rotating rod 3 is driven to frequently perform left and right reciprocating rotations, and then the second rotating shaft 5 and the lower grinding roller 6 are driven to frequently perform left and right reciprocating rotations, so that the lower grinding roller 6 and the upper grinding roller 9 cooperate to extrude and friction the drugs, and then grind the drugs into powder. The qualified ground powder falls on the guiding plate 15 through the blanking through groove 7, and then falls into the inner bottom of the grinding box 1 through the guiding plate 15. After grinding is completed, the sealed door plate is opened, and the ground powder after grinding can be centrally collected at the discharging port 14;

[0025] After all the drugs are ground, the lifting cylinder 10 is started. The lifting cylinder 10 drives the connecting rod 11 and the upper grinding roller 9 to move vertically upward. After the upper grinding roller 9 is moved above the grinding box 1 as a whole, it is convenient to clean the outer surface of the lower grinding roller 6 and the inner surface of the upper grinding roller 9 at this time, so that the cleaning of the outer surface of the lower grinding roller 6 and the inner surface of the upper grinding roller 9 is cleaner, thereby improving the quality of subsequent drug grinding.
