[0002] Pesticides refer to a substance or mixture of several substances and their preparations that are chemically synthesized or derived from biological or other natural substances and are used to prevent or control diseases, insects, weeds, rodents and other harmful organisms that harm agriculture and forestry, and to purposefully regulate the growth of plants and insects;

The scientific and rational use of pesticides is a key measure to ensure agricultural production safety and improve the quality of agricultural products;

[0004] At present, in the production process of pesticides, it is necessary to extract pesticide components from various raw materials, including extraction from plants. Plant-extracted pesticides, that is, botanical pesticides, are substances that use the toxic components contained in plants or their extracts to kill or inhibit pests. These toxic components are used to prevent and control pests in agriculture, such as tobacco, pyrethrum, derris, sophora flavescens and other plants. When using plants to extract pesticide components, the plants are coarsely crushed, and then the coarsely crushed plants are introduced into the extraction device, and the corresponding solvent is introduced so that the solvent dissolves and extracts the coarsely crushed plants. However, after the existing coarsely crushed materials are dissolved and extracted in the solvent, there are plant waste residues, which requires staff to filter and separate them later, which makes the process complicated, affects the processing efficiency, and is not convenient for removing the residue during the dissolution and separation process. For this reason, it is necessary to design a new technical solution to solve this problem. Summary of the Invention

[0036] As a preferred embodiment of the present application, the protrusion assemblies on the two extrusion plates are arranged staggered in the circumferential direction to avoid interference between the protrusion assemblies during extrusion.

[0037] By adopting the technical scheme, the staggered protrusion assemblies can avoid spatial obstacles between the protrusion assemblies on both sides during torsional extrusion.

[0038] Compared with the prior art, the present application has the following advantages:

[0039] The present application introduces the coarsely crushed plant raw material into the separation screen cylinder, and then enters the separation tank together with the separation screen cylinder, extracts the pesticide component by contacting the solvent and the raw material, ensures the effective precipitation of the pesticide component, and benefits from the fine structure of the separation screen cylinder, so that the residual residue generated during the extraction process can be accurately retained in the separation screen cylinder, thereby eliminating the subsequent filtering process of the staff, saving the filtering process, and further improving the efficiency of pesticide component extraction.

[0040] The extrusion assembly can extrude the material in the separation screen cylinder back and forth during the contact between the material and the solvent in the separation screen cylinder, so as to extrude the solvent absorbed in the plant raw material and the separated pesticide component, thereby improving the extraction effect of the pesticide component in the plant raw material, and the repeated extrusion enables the plant raw material to be broken twice.

[0041] During the extrusion of the material by the two extrusion plates driven by the extrusion assembly, the torsion assembly can drive the extrusion plates to rotate, and the two extrusion plates rotate in opposite directions, so as to realize torsional extrusion of the raw material during extrusion of the plant raw material, thereby improving the extrusion effect of the solvent and the pesticide component absorbed in the raw material.

[0042] The torsion assembly can store energy when driving the extrusion plate to twist and extrude the plant raw material, so that the spring can instantaneously release the thrust force when the extrusion plate moves back, so that the extrusion plate can quickly rotate, so that the protrusion assembly on the extrusion plate can quickly disperse the extruded material, so that the raw material can be dispersed when not subjected to extrusion force, so that the solvent can enter the inside of the dispersed plant raw material, thereby facilitating the effect of extracting pesticide components from the plant raw material using the solvent again, and the protrusion assembly can move the liquid outward when rotating quickly, and the liquid can quickly spread outside the separation net cylinder under the action of centrifugal force, thereby facilitating the diffusion of pesticide components, thereby facilitating the improvement of the extraction effect of pesticide components;

[0043] The protrusion assembly can be released and elongated at the moment of not being pressed, so that the protrusion assembly can more effectively contact the extruded material during rotation. The elongated protrusion assembly not only increases the contact area with the material, but also can more effectively penetrate the material layer due to its protruding shape, achieving a deep dispersion effect. This dispersion action not only helps to further crush the plant raw material and release more potential pesticide components, but also promotes the uniform distribution of the solvent in the material, thereby facilitating the improvement of the effect of separating and extracting pesticide components from the plant raw material.
