Problems solved by technology

At present, conventionally used road sweepers generally use a combination of brush plate sweeping and fan suction. This type of brush plate sweeping road sweeper has the following disadvantages: First, due to the unreasonable design of the fan, the noise of this type of equipment is relatively high. Large, and the cleaning efficiency is low; Second, the internal pipeline of the fan is not set properly, resulting in greater resistance to the airflow during operation and greater energy loss due to eddy currents, resulting in less suction and poor performance

Abstract

A special fan for a road sweeper comprises a fan housing, an impeller, a fan air inlet, an air inlet pipe, a silencer, a spindle, a bearing seat, a bearing and a support, wherein the impeller is arranged in the fan housing, the fan air inlet is arranged on the fan housing, the bearing seat and the bearing are used for supporting the spindle, and the support is used for supporting the integral fan. One end of the spindle is connected with the impeller, the other end of the spindle is driven by an engine of the road sweeper through a belt pulley, the fan is integrally fixed in a road sweeper carriage through the support, the air inlet pipe is arranged at the bottom of the road sweeper carriage, one end of the air inlet pipe is connected with the fan air inlet, and the other end of the air inlet pipe is connected with a sucker of the road sweeper. One end of the silencer is mounted at an air outlet of the fan housing, and the other end of the silencer penetrates through the top of the carriage to the atmosphere. The special fan is simple in structure and low in noise. By accurately arranging internal components of the fan and optimizing the runner of the fan, fluid in the runner can flow more smoothly to be more accordant with practical runner state of airflow in the runner, loss caused by vortex is reduced and efficiency of the special fan for the road sweeper is improved.

Description

technical field [0001] The invention relates to a special component for a road sweeping vehicle, in particular to a special fan for collecting ground garbage on the road sweeping vehicle. Background technique [0002] Road sweeper is a new type of high-efficiency cleaning equipment integrating road cleaning, garbage recycling and transportation. Its development and application have greatly promoted the development of road sweeper. With the market demand, road sweeper has also changed from a single pure sweeping Developed to the current various forms, the new energy and quality of products have been rapidly improved. At present, conventionally used road sweepers generally use a combination of brush plate sweeping and fan suction. This type of brush plate sweeping road sweeper has the following disadvantages: First, due to the unreasonable design of the fan, the noise of this type of equipment is relatively high. Second, the internal piping of the fan is unreasonably set,...
