AI Technical Summary

Technical Problem

The manual cleaning of air filters for existing engineering vehicle engines is inefficient and costly. Furthermore, existing automatic dust removal devices are complex in structure, prone to jamming, and have poor sealing, resulting in incomplete dust removal and affecting engine life.

Method used

An air filtration device for an engineering vehicle engine was designed. It employs a dust-collecting and feeding assembly and a synchronization assembly to achieve automatic synchronous opening and closing of the filter screen and the opening and closing arc plate. It utilizes the negative pressure of the engine intake air to assist in dust removal, and combines a mechanical linkage mechanism to ensure precise synchronization, avoid jamming, and ensure sealing.

Benefits of technology

It enables automatic cleaning of accumulated dust without manual disassembly of the filter element, reducing maintenance time and costs, ensuring filtration efficiency, extending engine life, and avoiding secondary pollution caused by incomplete dust removal.

Abstract

The invention provides an engineering vehicle engine air filtering device which comprises an air filtering bin, the upper end of the air filtering bin is provided with an engine connector, the side end of the air filtering bin is provided with a dust suction inlet, the inner end of the dust suction inlet is connected with an exhaust pipeline, the lower end of the exhaust pipeline is provided with a dust exhaust cylinder, and the outer end of the exhaust pipeline is provided with at least two sets of concave pipe grooves. A filter is arranged in the middle of the exhaust pipeline, and the dust guiding and discharging assembly comprises a filter screen plate rotatably arranged at the lower end of the filter; the extension clamping plate is fixedly connected to the opening and closing end of the filter screen plate; the dust outlet channel is arranged below the extension clamping plate; the opening and closing arc-shaped plate is rotatably arranged at the outer end of the dust outlet channel, and the periphery of the opening and closing arc-shaped plate is wrapped with a sealing ring. The problems that an existing engineering vehicle engine air filter is low in manual cleaning efficiency and high in maintenance cost, and an existing automatic dust exhaust device is complex in structure, prone to clamping stagnation and poor in sealing performance, so that dust exhaust is not thorough, and the service life of an engine is affected are solved.
