An automatic dust-proof device for air intake of a trencher

Abstract

The invention discloses an automatic dust-proof device for air intake of a ditching machine, which relates to the technical field of agricultural machinery and includes an air intake pipe, an air filter and a dust-proof device. The air filter is installed in the middle of the air intake pipe. The dust-proof device is installed on the inlet port of the air intake pipe, and it is characterized in that the dust-proof device includes a clip frame, a detection device, a square grid frame, a net box, a net box and a winding device. In the environment, the air carrying dirt and dust in the environment passes through the gauze on the square frame, most of the dirt and dust are blocked by the gauze to form a filtering effect, which reduces the workload of the air filter and prolongs its service time; and the gauze The area of ​​the net on the square net frame is larger than the area of ​​the air intake port of the air intake pipe, thereby reducing the air flow resistance caused by the gauze, which is better than the traditional gauze wrapping the air intake directly at the air intake pipe port.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to an automatic dust-proof device for air intake of a trencher. Background technique [0002] During the ditching process of the ditching machine, the ditching device continuously excavates and sprinkles the soil, resulting in a lot of mud and dust in the ditching environment. For the normal operation of the engine, gauze wrapping is generally used for preliminary filtration to avoid frequent cleaning and replacement of the air filter, thereby reducing the cost of filter replacement and prolonging the service life of diesel engine cylinder liners and pistons. [0003] Among them, the gauze will gradually be blocked by mud and dust and become invalid during use, and the gauze needs to be replaced repeatedly for cleaning, and generally only after the machine is shut down, resulting in the need to reduce the use time of the gauze and increase the dismantling time.

AI Technical Summary

Problems solved by technology

[0004] The invention proposes an air intake automatic dust-proof device for a ditching machine, aiming to solve the problem of reducing the service time of the gauze net and increasing the frequency of disassembly and cleaning in order to avoid the failure of the gauze net to affect the generator during the ditching process. Normal work, further increasing the burden on the staff to replace and clean the gauze
