Description

Technical Field

[0001] The invention belongs to the technical field of screening equipment, and in particular relates to a biological pesticide particle size screening device. Background Art

[0002] When screening biopesticide particles, since most biopesticide particles are cylindrical or irregular particles, and are affected by gravity when added to the screening device, the biopesticide particles are easily stuck at the sieve opening. Conventional vibration is difficult to completely remove the biopesticide particles stuck at the sieve opening, which results in the screening efficiency being yet to be improved.

[0003] In view of this, a biological pesticide particle size screening device is proposed. Summary of the invention

[0004] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments.

[0034] Specifically, the surfaces of the filter plate 1 200, the filter plate 201 and the filter plate 3 202 are all provided with filter holes 203 distributed at equal intervals, wherein the diameters of the filter holes 203 on the filter plate 1 200, the filter plate 201 and the filter plate 3 202 are different, wherein the aperture of the filter hole 203 on the filter plate 1 200 is larger than the aperture of the filter hole 203 on the filter plate 201 and the filter plate 3 202, at this time, after all the pesticide particles fall on the filter plate 1 200, they will be divided into three categories according to the aperture, and the filter hole 203 on the filter plate 3 202 is used to export dust;

[0035] Specifically, the dredging assembly includes a carrier 301 and a protrusion 302. The end of the carrier 301 is fixedly connected to the carrier plate 300, and the protrusion 302 is fixedly connected to the top of the carrier 301. The top of the protrusion 302 is arc-shaped, so as to facilitate the dredging of pesticide particles stuck in the filter hole 203.

[0036] Specifically, the cam frame 400 is arranged on the carrying plate 300, and the axes of the multiple cam frames 400 are commonly provided with a coupling shaft 401, and the multiple coupling shafts 401 pass through one end of the screening box 100 and are transmitted through a pulley and a transmission belt 402; a support frame 403 is arranged on the outer side of the screening box 100, and a motor 404 is installed on the inner edge of the support frame 403, and the output end of the motor 404 is connected to any coupling shaft 401, so that after one of the coupling shafts 401 is driven, the remaining coupling shafts 401 can also be driven synchronously.

[0037] Through this implementation, it can be achieved that: by running the motor 404, one of the coupling shafts 401 is rotated, and under the action of the transmission belt 402, multiple coupling shafts 401 can rotate synchronously. At this time, when the cam frame 400 rotates, it can drive the filter plate 1 200, the filter plate 201 and the filter plate 3 202 to reciprocate. When the filter plate 1 200 and the filter plate 201 descend, the tip of the protrusion 302 is inserted into the filter hole 203. At this time, the pesticide particles stuck in the filter hole 203 can be pushed upward. When the filter plate 1 200 and the filter plate 201 rise, the protrusion 302 keeps a distance from the filter hole 203, and the normal circulation of pesticide particles is not affected by the tip shape of the protrusion 302.

Through the cooperation of the outlet 101 and the door stopper 102, the pesticide particles screened on the filter plate 1 200, the filter plate 201 and the filter plate 3 202 can be classified and taken out; the surface of the screening box 100 is fixedly connected with a gear 1 500, and the outer side of the screening box 100 is provided with a support seat 502, and the inner edge of the support seat 502 is rotatably connected with a gear 2 505, wherein the support seat 502 is provided with a motor for controlling the rotation of the gear 2 505, and the gear 2 505 is meshed with the gear 1 500 for transmission, so that the screening box 100 can be driven to rotate.

[0040] Furthermore, a guide groove 501 is provided on the surface of the screening box 100, a guide block 504 is slidably connected in the guide groove 501, support plates 503 are butted on both sides of the support seat 502, the guide block 504 is butted against the inner edge of the support plate 503, and the guide block 504 slides in the support plate 503, so that the screening box 100 can be guided and loaded when rotating.

[0041] Through this implementation, it can be achieved that: under the action of gear two 505 and gear one 500, the screening box 100 can be rotated, and the stability of the screening box 100 during rotation can be ensured through the guide groove 501, the support plate 503 and the guide block 504. When the screening box 100 rotates, the pesticide particles on the filter plate one 200, the filter plate two 201 and the filter plate three 202 can be spread out, so that too many pesticide particles on one side can be avoided. When collecting the pesticide particles that need to be screened on the filter plate one 200, the filter plate two 201 and the filter plate three 202, the screening box 100 is rotated to a tilted state, and the pesticide particles can be easily collected through the setting of the outlet 101 and the door stop 102.
