Description

Technical Field

[0001] This utility model relates to the field of powder spraying hoods, specifically a mechanical powder spraying hood for corn pests and diseases. Background Technology

[0002] In corn cultivation, pest and disease control relies on dusting equipment, but existing dusting hoods have significant drawbacks: First, they lack the ability to adjust the amount of powder sprayed. Most dusting hoods have a fixed number of spray holes, making it impossible to flexibly adjust the pesticide output according to the severity of corn pests and diseases or the plant's growth stage, which can easily lead to pesticide waste or insufficient control. Second, when not in use, they lack an effective sealing structure, leaving the spray nozzles directly exposed. External dust and impurities can easily enter the interior, affecting the quality of the pesticide powder. Additional cleaning is required before each use, increasing maintenance costs. Therefore, it is necessary to design a mechanical dusting hood for corn pests and diseases to solve these problems. Utility Model Content

[0003] The purpose of this invention is to provide a mechanical dusting hood for corn pests and diseases, in order to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a mechanical powder spraying hood for corn pests and diseases, including a feed pipe, the right side of which is connected to the powder spraying hood, the inner wall of which is provided with powder spraying holes, and a plurality of powder spraying holes are provided, the left side of the inner cavity of the powder spraying holes is rotatably connected to a sleeve through an opening, and the left end of the sleeve is provided with a shielding mechanism.

[0005] Preferably, the blocking mechanism includes a turntable fixedly connected to the left end of the sleeve, a first sealing strip is fixedly installed on the right side of the turntable, and a plurality of the first sealing strips are arranged in a ring, and a second sealing strip is fixedly installed on the right side of the turntable, and a plurality of the second sealing strips are arranged in a ring.

[0006] Preferably, an iron block is slidably connected inside the sleeve, a slide rod is fixedly installed on the right side of the iron block, the right end of the slide rod passes through the sleeve and extends to the outside of the sleeve, a gear is fixedly installed on the right end of the slide rod, and a gear cylinder that cooperates with the gear is fixedly installed on the left side of the inner cavity of the powder spraying hood.

[0007] Preferably, a magnetic block is fixedly installed on the left side of the inner cavity of the sleeve.

[0008] Preferably, a traction rod is fixedly installed on the right side of the gear.

[0009] Preferably, a handle is fixedly installed at the right end of the traction rod.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. This mechanical powder sprayer for corn pests and diseases works by pulling the handle to the right and rotating it. The handle drives the traction rod to rotate, which in turn drives the gear to rotate. The gear then drives the slide rod to rotate, which in turn drives the iron block to rotate. The iron block then drives the sleeve to rotate, which in turn drives the turntable to rotate. The turntable rotates the second and first sealing strips. When the first sealing strip is fully in contact with the powder spraying hole, it can seal the inside of the powder sprayer. When the second sealing strip rotates to be in contact with the powder spraying hole, it can seal half of the powder spraying hole, thus adjusting the amount of powder sprayed.

[0011] 2. This mechanical powder sprayer for corn pests and diseases, by setting up magnetic blocks and iron blocks, allows the gear to be inserted back into the gear cylinder after adjustment. After the gear enters the gear cylinder, it can limit and fix the rotating second or first sealing strip. At the same time, the magnetic blocks and iron blocks attract each other to prevent the gear from moving, thereby improving the stability of the device after adjustment. Attached Figure Description
