Description

Technical Field

[0001] The utility model relates to the technical field of pesticide production, in particular to vacuum feeding equipment for the production of 2-amino-4,6-dimethoxypyrimidine. Background Art

[0002] Pesticides refer to chemically synthesized substances or mixtures of substances or several substances derived from biological or other natural substances and their preparations used to prevent and control diseases, insects, weeds, rats and other harmful organisms that harm agriculture and forestry, and to purposefully regulate the growth of plants and insects. They are widely used in agricultural, forestry and animal husbandry production, environmental and household hygiene pest control and epidemic prevention, and industrial product mildew and moth prevention. 2-Amino-4,6-dimethoxypyrimidine is a pesticide intermediate used to synthesize sulfonylurea pesticides. Vacuum feeding equipment is required in the production of 2-amino-4,6-dimethoxypyrimidine.

[0003] Announcement No. (CN220200698U) discloses a vacuum loader that is convenient for quantitative loading. The pulling block is pulled to make the rear end of the second guide rod move away from the fourth connecting hole. The rotating rod is rotated to adjust the gap between the circular baffle plate and the inner wall of the discharge barrel to control the discharge speed and amount. After adjustment, the pulling block is released to insert the rear end of the second guide rod into the corresponding fourth connecting hole. The circular baffle plate is limited by the second spring to stabilize the circular baffle plate during the falling process of granular and powdered materials. The height of the discharge port in the above device cannot be adjusted according to usage requirements, which will result in poor use of the device and needs to be improved. Utility Model Content

The descending plate 207 is rotatably connected, and the thickness of the fixed plate 203 and the lifting plate 207 is the same, both of which are 0.5 cm; when the height of the discharge port needs to be adjusted, the threaded cylinder 205 is rotated, and the threaded cylinder 205 drives the rotating seat 206 to rotate. At the same time, the rotating threaded cylinder 205 descends under the action of the threaded rod 204, and the rotating seat 206 descends accordingly. The descent of the rotating seat 206 drives the lifting plate 207 to descend, and the lifting plate 207 drives the lifting tube 208 to descend along the fixed tube 202. When the lifting tube 208 descends to the corresponding height, the threaded cylinder 205 is stopped, and then the loading operation can be carried out.

[0032] In the above structure: when the height of the discharge port needs to be adjusted, the threaded barrel 205 is rotated, and the threaded barrel 205 drives the rotating seat 206 to rotate. At the same time, the rotating threaded barrel 205 descends under the action of the threaded rod 204, and the rotating seat 206 descends accordingly.
