Sweeper with lifting function

Abstract

The invention discloses a sweeper with a lifting function, which comprises a sweeper chassis, a power device, a lifting device and a front wheel device. The power device comprises a differential motorand a rear wheel device. The rear wheel device comprises a first sprocket, a second sprocket, a support plate and a rear wheel. The middle part of the support plate is rotatably installed on the output shaft of the rear axle, the lower part is vertically arranged in the middle part, and the upper part is inclined to the right. A first sprocket is fixedly mounted on the output shaft of the rear axle, and a second sprocket is fixedly mounted on one end of the first support shaft and connected through a transmission chain. The lifting device comprises a first cylinder, a third sprocket, a lifting chain, a upright post and a connecting rod; The piston rod of the first cylinder is connected with a push plate sliding on the upright post, one end of the lifting chain is fixedly connected with the push plate, and the other end is connected with the connecting rod around the outside of the third sprocket. The utility model has the function of lifting and lowering, has a simple structure, realizes the adjustment of the height of the chassis of the sweeper while the sweeper is running normally, and smoothly passes through obstacles.

Description

technical field [0001] The invention relates to the field of cleaning vehicles, in particular to a cleaning vehicle with lifting function. Background technique [0002] With the process of urbanization and modernization in our country, the requirements for city appearance and sanitation are getting higher and higher. Micro and small road sweepers are widely used on narrow and curved roads such as back streets, alleys, slow lanes, and sidewalks due to their small size and flexibility, low operating threshold, and low operating costs, as well as their unique functions of cleaning and cleaning. , to ensure its quick cleaning and cleaning. [0003] The existing micro- and small-scale road cleaning and cleaning vehicle industry has just started. It is mainly a kind of floor-sweeping vehicle with a modified road-cleaning function on the chassis of a special vehicle.

[0003] The existing micro- and small-scale road cleaning and cleaning vehicle industry has just started. It is mainly a kind of floor-sweeping vehicle with a modified road-cleaning function on the chassis of a special vehicle. In addition to the chassis engine, the vehicle drives cleaning and recycling by adding a hydraulic motor. This type of micro 1. The small road cleaning and cleaning vehicle has a simple structure and flexible operation. It is suitable for cleaning operations in various climates. However, due to long-term exposure and use on back streets, alleys, slow lanes, sidewalks and other road surfaces, the road surface is easy to be uneven, and there are often some unevenness. For the convenience of cleaning, the chassis of existing sweeping vehicles is often lower than the ground to ensure that the cleaning device is in full contact with the ground. Therefore, when driving on uneven roads, the chassis of the sweeping vehicle cannot be adjusted in height, which is easy to cause the chassis of the sweeping vehicle or cleaning The device collides with a raised obstacle on the road surface, affecting the cleaning operation
