Rotary type wheel pressing device

Abstract

The invention relates to a rotary type wheel pressing device. The rotary type wheel pressing device is installed on the front portion of a sweeping type motor sweeper sweeping system and comprises two land wheel fixing supports, two land wheels, a rubber idler wheel and a land wheel center shaft, wherein the land wheels are installed at the two ends of the land wheel center shaft correspondingly; the portion, between the two land wheels, of the center shaft is sleeved with the rubber idler wheel; the outer diameter of the rubber idler wheel is smaller than the outer diameters of the two land wheels; the land wheel fixing supports are installed in the positions, outside the land wheels, of the center shaft; the horizontal positions of rotary pins of the land wheel fixing supports are not lower than that of the land wheel center shaft; and limiting sleeves are arranged between the land wheel fixing supports and the land wheels. The rotary type wheel pressing device rotates due to the dual functions of the forward inertia of a vehicle and ground friction force and basically does not consume any energy, so that energy consumption is reduced, and the work efficiency is improved. In addition, the rotary type wheel pressing device has the advantages of being simple in structure, reasonable in design, convenient to mount and dismount and the like.

Description

technical field [0001] The invention belongs to the technical field of sweeping brush cleaning vehicles, in particular to a rotary wheel pressing device. Background technique [0002] At present, as one of the sanitation equipment, the road sweeper is mainly used for cleaning objects such as gravel, dust, leaves, plastic bags and other household garbage in modern cities. The existing known cleaning systems have obvious cleaning effects on gravel, dust, etc., but except for the suction-sweeping cleaning system with a motor power of more than 50kw, which has a certain effect on cleaning leaves, there is no strong ductility on leaves, plastics, etc. A system that has a noticeable effect on trash removal. [0003] The suction-sweeping cleaning system uses high-power motor blowing to blow out the air in the garbage collection box and the closed cleaning mechanism, forming a negative pressure in the entire system, generating strong pressure to suck in dust and other garbage.

AI Technical Summary

Problems solved by technology

This cleaning method requires powerful suction, so the power of the fan motor is very large, generally up to about 20KW, and even up to 50-60KW for large-scale sweepers. For pure electric sweepers, such a large power will be very fast. Consumes the energy stored in the battery. Therefore, the operating time of pure electric suction sweeping sweepers is mostly about 3 hours, which is not enough to support the work of eight hours a day.

At the same time, according to the data, the cleaning effect on leaves and plastics with strong ductility is about 80%. When there is a large amount of leaves on the road (such as autumn windy weather), the cleaning effect is ordinary, and the power is too large. Application on electric sweeper
