Description

Technical Field

[0001] The utility model belongs to the technical field of grinding devices, in particular to a grinding device for powdered pesticide raw materials. Background Art

[0002] Pesticides are a chemically synthesized substance or a mixture of several substances or their preparations derived from biological or other natural substances used to prevent and control diseases, insects, weeds, rats and other harmful organisms that harm agriculture and forestry, and to purposefully regulate the growth of plants and insects. Pesticides are widely used in agricultural, forestry and animal husbandry production, environmental and household hygiene pest control and epidemic prevention, and industrial product mildew and moth prevention. According to their uses, they can be mainly divided into insecticides, acaricides, rodenticides, nematicides, molluscicides, fungicides, herbicides, plant growth regulators, etc.

[0003] In the prior art, powdered pesticides are a common pesticide formulation in the form of powder. They are usually made from raw materials of plant or animal origin, and achieve control effects by interfering with the physiological processes of pests or causing direct toxic effects on them. During long-term use observations, it was found that when powdered pesticides are currently ground, most of them are ground once after the pesticide raw materials are introduced, until a large amount of pesticide raw materials are crushed. During the grinding process, the ground pesticides need to wait until the unfinished pesticides are ground before being collected together. During the grinding process, the ground pesticides will increase the grinding resistance in the grinding bucket, resulting in low grinding efficiency.

[0004] To this end, the utility model provides a powder pesticide raw material grinding device. Utility Model Content
