The primary gear 16 is in meshing engagement with the secondary gear 26. The rotating shaft 22 can be controlled to rotate the connecting plate 23, the vertical scraping strip 24 and the horizontal scraping strip 25 by the meshing transmission of the primary gear 16 and the secondary gear 26. The vertical scraping strip 24 is used for scraping and cleaning the inner side wall of the liquid pesticide raw material screen cylinder 10, and the horizontal scraping strip 25 is used for scraping and cleaning the bottom inner wall of the liquid pesticide raw material screen cylinder 10, so as to avoid the adhesion and accumulation of impurities on the inner wall of the liquid pesticide raw material screen cylinder 10 and affect the screening effect, and ensure the continuous and stable and smooth filtering performance of the liquid pesticide raw material screen cylinder 10.

[0028] In the embodiment, the bottom end aperture size of the solid pesticide raw material feeding hopper 4 is smaller than the aperture size of the first material falling hole 17, and the aperture size of the first material falling hole 17 is smaller than the aperture size of the second material falling hole 18, so as to ensure that the solid pesticide raw material in the solid pesticide raw material feeding hopper 4 sequentially and smoothly passes through the first material falling hole 17 and the second material falling hole 18 and enters the purification and impurity removal cylinder 1 and falls on the solid pesticide raw material screen plate 8.

[0029] In the embodiment, the upper surface and the lower surface of the primary gear 16 are smooth planes, the top surface of the purification and impurity removal cylinder 1 is a smooth plane, the lower surface of the primary gear 16 is in sliding contact with the top surface of the purification and impurity removal cylinder 1, and the bottom end of the solid pesticide raw material feeding hopper 4 is in sliding contact with the upper surface of the primary gear 16, so as to ensure the smooth rotation of the primary gear 16.

[0030] In the embodiment, the rotating shaft 22 is fixedly provided with a stirring rod 27 located below the liquid pesticide raw material screen cylinder 10. The number of the stirring rods 27 is multiple and uniformly distributed.

[0031] In the embodiment, the purification and impurity removal cylinder 1 is fixedly provided with a residue receiving box 28 located below the residue discharging hole 9 on the left side outer wall. The top of the residue receiving box 28 is of an open structure. The residue receiving box 28 is used for collecting the solid impurities screened out.

[0032] In the embodiment, the cleaning hole 29 is arranged at the top of the purification and impurity removal cylinder 1, and is communicated with the liquid pesticide raw material screen cylinder 10, so as to clean the impurity particles in the liquid pesticide raw material screen cylinder 10.

[0033] In the embodiment, it should be noted that the motor 14 can be purchased in the market, and the motor 14 is provided with a power supply, and the wiring connection mode and the control mode belong to the mature technology in the art, so as to fully disclose and describe, and therefore, the text will not be described again.

[0034] Through the above structure, the working principle of the pesticide raw material purification and impurity removal device is as follows:

[0035] By pouring the solid pesticide raw material into the solid pesticide raw material feeding hopper 4, the solid pesticide raw material can fall through the first falling hole 17 and the second falling hole 18 to the solid pesticide raw material screen plate 8 in the purification and impurity removal cylinder 1, and the solid pesticide raw material screen plate 8 can be used to screen and remove impurities from the solid pesticide raw material. The solid pesticide raw material which is screened and removed clean falls through the screen hole of the solid pesticide raw material screen plate 8 to the bottom inner wall of the purification and impurity removal cylinder 1, and the impurities screened out are finally discharged from the residue discharge hole 9 into the residue receiving box 28 along the inclined direction of the solid pesticide raw material screen plate 8, so as to ensure the purity of the solid pesticide raw material. By pouring the liquid pesticide raw material into the liquid pesticide raw material feeding hopper 6, the liquid pesticide raw material enters the liquid pesticide raw material screen cylinder 10, and the liquid pesticide raw material screen cylinder 10 can be used to filter and purify the liquid pesticide raw material. The filtered liquid pesticide raw material falls through the screen hole of the liquid pesticide raw material screen cylinder 10 to the bottom inner wall of the purification and impurity removal cylinder 1, and the impurities screened out are retained in the liquid pesticide raw material screen cylinder 10, so as to ensure the purity of the liquid pesticide raw material. In turn, the solid pesticide raw material and the liquid pesticide raw material can be simultaneously purified and impurity-removed, so that the purified solid pesticide raw material and the liquid pesticide raw material are mixed in the bottom space of the purification and impurity removal cylinder 1;

[0036] During the impurity removal process of solid and liquid pesticide raw materials, the motor 14 is started to drive the vertical shaft 15, the main gear 16, the plurality of elastic rubber rods 20, the plurality of elastic rubber balls 21 and the plurality of stirring rods 27 to rotate. At this time, the bottom end of the solid pesticide raw material feeding hopper 4 intermittently communicates with the material falling hole 17, and the solid pesticide raw material can fall intermittently onto the solid pesticide raw material sieve plate 8, so as to accurately control the feeding amount of the solid pesticide raw material, thereby avoiding the problem that the amount of solid pesticide raw material falling onto the solid pesticide raw material sieve plate 8 is too large, which leads to incomplete screening and impurity removal of the solid pesticide raw material. In addition, the rotation of the vertical shaft 15 drives the elastic rubber rods 20 and the elastic rubber balls 21 to rotate, so that the plurality of elastic rubber balls 21 and the metal impact strips 19 collide intermittently. The vibration force generated by the collision can be transmitted to the solid pesticide raw material sieve plate 8 through the baffle 7, so as to accelerate the screening and impurity removal efficiency of the solid pesticide raw material sieve plate 8. The meshing transmission action of the main gear 16 and the secondary gear 26 can control the rotation of the shaft 22, the connecting plate 23, the vertical scraping strip 24 and the horizontal scraping strip 25. The vertical scraping strip 24 can scrape and clean the inner side wall of the liquid pesticide raw material sieve cylinder 10, and the horizontal scraping strip 25 can scrape and clean the bottom inner wall of the liquid pesticide raw material sieve cylinder 10, so as to avoid the problem that the impurities adhere and accumulate on the inner wall of the liquid pesticide raw material sieve cylinder 10, which affects the screening effect, ensures the continuous and stable filtering performance of the liquid pesticide raw material sieve cylinder 10, and further realizes efficient and comprehensive purification and impurity removal of the solid and liquid pesticide raw materials. In addition, the rotation of the vertical shaft 15 drives the plurality of stirring rods 27 to rotate, which can uniformly mix the solid and liquid pesticide raw materials after purification and impurity removal, which is helpful for subsequent processing and further improves the work efficiency.

[0037] After the work is completed, the motor 14 is stopped, and the discharge valve 12 on the discharge pipe 11 is opened. The pesticide raw material after purification and impurity removal and mixing can be discharged through the discharge pipe 11, and the entire purification and impurity removal process is completed.
