[0030] Embodiment 2

[0031] like Figure 1-Figure 4 As shown, the utility model proposes a filtering device for preparing a pesticide suspension.

[0032] like Figure 2 As shown, the recoil assembly includes a recoil pipe 10 and a recoil head 11. The recoil pipe 10 is arranged as an L-shaped structure, the horizontal section of which passes through the filter box 1 and is connected with a flange, and both sides of the vertical section are provided with multiple groups of recoil heads 11 facing the filter screen 3; the horizontal section located on the inner side of the filter box 1 is provided with a corrugated connecting section 12.

[0033] The corrugated connecting section 12 serves as a flexible section in the middle of the recoil tube 10 , so that when the vertical section moves, the corrugated connecting section 12 will shrink adaptively.

The impurities generated during the mixing preparation process are filtered out by the filter 3, and the recoil pipe 10 is connected to the external high-pressure pump through the flange, so that the high-pressure pump draws external water into the recoil pipe 10, and sprays it through the recoil head 11 to reversely flush the filter 3. During the flushing process, the main shaft 7 drives the main bevel gear 15 to rotate, and the main bevel gear 15 is meshed with the slave bevel gear 16. The meshing force drives the screw 13 to rotate. During the rotation of the screw 13, the vertical section of the recoil pipe 10 is driven to move through the slider 14, thereby expanding its backwashing area, thereby improving the comprehensiveness and cleaning effect of the backwashing of the filter 3.
