[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The utility model embodiment discloses a circulating refrigeration machine for producing insecticides.

[0026] The utility model provides Figure 1-3 A circulating refrigerator for insecticide production shown in the figure comprises a refrigerator 1 and a fan blade 2 arranged inside the refrigerator 1, a filter screen 3 is fixedly embedded on the side of the refrigerator 1, two symmetrically arranged baffles 4 are fixedly arranged on the outer wall of the refrigerator 1, cross bars 5 are rotatably provided at both ends of the side walls of the baffles 4, sprockets 6 are fixedly sleeved on the rod walls of the two cross bars 5, a chain 7 is provided on the outer sides of the two sprockets 6, a cleaning brush 8 is fixedly provided at the chain link of the chain 7, the cleaning brush 8 is conically arranged on the side away from the chain 7, and the cleaning brush 8 is arranged in coordination with the outer wall of the filter screen 3.

[0027] During the insecticide production process, the refrigerator 1 is running and its internal fan blades 2 rotate. At this time, the external airflow can be filtered when entering the refrigerator 1 through the filter 3, so that the dust in the air is blocked on the outside of the filter 3. During the operation of the refrigerator 1, the two cross bars 5 drive the sprocket 6 and the chain 7 to rotate and circulate. At this time, the chain 7 drives the cleaning brush 8 to rotate and can contact the outer wall of the filter 3. During the contact between the cleaning brush 8 and the filter 3, the dust on the surface of the filter 3 can be pushed and cleaned, ensuring that the filtering effect of the filter 3 is stable and avoiding the dust from affecting the refrigeration effect of the refrigerator 1 as much as possible.

[0028] In order to avoid the need for external energy, the crossbar 5 and the chain 7 can be driven by the refrigerator 1 itself. Figure 2-3As shown, a rotating rod 9 is fixedly provided at the middle end of one side of the fan blade 2 close to the filter screen 3, and a driving mechanism is provided on the rod wall of the rotating rod 9. The driving mechanism includes a support plate 10, which is fixedly provided at the internal upper end of the refrigerator 1. A vertical rod 11 is rotatably provided inside the support plate 10, and first bevel gears 12 are fixedly provided at both ends of the vertical rod 11. A transmission rod 13 is rotatably provided at the upper end of the inner wall of the refrigerator 1, and a second bevel gear 14 and a third bevel gear 15 are fixedly provided on the rod walls of the rotating rod 9 and the transmission rod 13, respectively. The two first bevel gears 12 are meshed with the second bevel gear 14 and the third bevel gear 15, respectively. A first pulley 16 is provided on the rod wall fixing sleeve of the upper cross bar 5, and a second pulley 17 is provided on the rod wall fixing sleeve of the transmission rod 13. The first pulley 16 and the second pulley 17 have different outer diameter specifications. A belt 18 is provided for transmission between the first pulley 16 and the second pulley 17, and a through hole for matching the belt 18 transmission is opened inside the side of the refrigerator 1 close to the filter screen 3.

[0029] When the fan blades 2 inside the refrigerator 1 rotate, the rotating rod 9 rotates accordingly. At this time, supported by the support plate 10, the vertical rod 11 can rotate through the meshing of the first bevel gear 12 and the second bevel gear 14 below. At the same time, the meshing of the second bevel gear 12 and the third bevel gear 15 above, the transmission rod 13 can rotate simultaneously with the rotating rod 9 and the vertical rod 11. At this time, through the transmission of the first pulley 16, the second pulley 17 and the belt 18, the cross bar 5 starts to drive the sprocket 6 to rotate. At this time, the chain 7 can be stably transmitted, and thereby drive the cleaning brush 8 to contact the filter 3 to complete the cleaning work.

[0030] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
