Abstract

The invention discloses a ventilation device for building machinery, which comprises a base and is characterized in that a collecting box is fixed at the upper end of the base, a mounting frame is fixed at the upper end of the collecting box, the inner wall of the mounting frame is connected with a suction hopper through a mounting spring, and a corrugated pipe is fixed at the bottom of the suction hopper; the corrugated pipe is communicated with the inner wall of the collecting box, two sliding sleeves are fixed to the inner wall of the collecting box, sliding plates are connected to the inner walls of the two sliding sleeves through shaking springs, a filter screen is fixed to the upper ends of the two sliding plates, and the filter screen and the sliding plates are in sealed sliding connection with the inner wall of the collecting box. The dust removal device has the advantages that the suction hopper is transferred in multiple directions and circularly swings around the circumference, comprehensive suction can be achieved, dust in the environment can be effectively removed, dust in the area can be comprehensively removed, the suction hopper does not swing in a large cross mode, and therefore the overall swing amplitude is relatively small, the frequency is high, the coverage area is enlarged, and the stability is improved.

Description

technical field [0001] The invention relates to the technical field of construction machinery, in particular to a ventilation device for construction machinery. Background technique [0002] Construction machinery is a general term for machinery and equipment used in engineering construction and urban and rural construction. Generally, suitable ventilation devices are required, otherwise dust or material dust will be easily inhaled by workers, causing harm to workers' health; [0003] After searching, the invention patent of Chinese Patent Publication No. CN112139194B discloses a ventilation device for construction machinery, including an air inlet hopper, a hose, a dust box, a filter screen, a dust drop pipe, a dust collection box, an air inlet pipe, a fan, Air outlet duct, water tank and rack; the size of the opening of the air inlet hopper gradually increases along the direction away from the hose, and the air inlet hopper is connected with the frame in rotation, and can ...
