Abstract

The invention discloses pressurization equipment for a cab of engineering machinery, and relates to the technical field of manufacturing of engineering machinery. The pressurization equipment comprises a filter and a shell, a gas inlet and an air outlet pipe are arranged on the shell; the filter comprises a primary filter arranged at the gas inlet in the shell and a secondary filter arranged behind the primary filter; the secondary filter divides the inner space of the shell into a first cavity and a second cavity; an automatic dust collector is arranged at the bottom of the first cavity; an air blower is arranged in the second cavity and is communicated with the cab through the air outlet pipe. Compared with the prior art, the pressurization equipment has the advantage that the problems that an existing pressurization system is poor in pressurization effect and inconvenient to repair and maintain are solved.

Description

technical field [0001] The invention relates to the technical field of construction machinery manufacturing, in particular to a pressurization device used in a construction machinery cab. Background technique [0002] Construction machinery loaders, excavators, bulldozers, cranes and other products often need to work in toxic, harmful, and highly dust-polluted environments. The cabs of most domestic construction machinery are limited by cost and manufacturing process, so it is difficult to achieve a truly sealed cab. Therefore, the surrounding toxic and harmful gases and dust can easily enter the interior of the cab, which is harmful to the operator's body. impact on health and safety. At present, only HVAC air-conditioning units are installed in the cab of construction machinery or the compressed gas of the air compressor is input into the cab by connecting pipes and filters to improve the internal air environment. These two methods have shortcomings in the process of use...
