Snow pushing device

Abstract

The invention discloses a snow pushing device comprising a snow pushing board and a supporting device. The snow pushing board is connected with the supporting device, and the other end of the supporting device is connected with a main engine in a hinged mode; the snow pushing board is connected with the supporting device through a connecting rod mechanism, and the connecting rod mechanism comprises an upper connecting rod, a lower connecting rod, an upper limiting position and a lower limiting position; one end of the upper connecting rod and the snow pushing board are hinged at a point A, and the other end of the upper connecting rod and the supporting device are hinged at a point B; one end of the lower connecting rod and the snow pushing board are hinged at a point C, and the other end of the lower connecting rod and the supporting device are hinged at a point D; the point A and the point B are both arranged above the point C and thepoint D; the movement range of the upper connecting rod is limited by the upper limiting position so that backward turning of the snow pushing board can be avoided; and the movement range of the lower connecting rod is limited by the lower limiting position so that forward turning of the snow pushing board can be avoided. The snow pushing device has the beneficial effects of being capable of quickly passing ground obstacles, and achieving large snow pushing quantity at a time and high reliability.

Description

technical field [0001] The patent of the present invention relates to a snow removal device, in particular to a segmented and independent snow removal device for crossing obstacles with a snow pusher, which belongs to the technical field of construction machinery. Background technique [0002] Most of the snow removal devices are used in urban roads and highways that affect people's daily travel, and are widely used by municipal departments and sanitation departments. At present, most commonly used snow removal devices use wheeled loaders (including wheel loaders, backhoe loaders, and skid steer loaders) or trucks as the main engine to perform fast-moving mechanical snow removal operations, which are usually removed with ordinary buckets. Bucket teeth, adding a blade or using an integrated snow pusher as a snow removal device to shovel or push snow, but there are problems such as easy damage to the ground, poor adaptability to local unevenness of the ground, and easy damage ...

AI Technical Summary

Problems solved by technology

At present, most commonly used snow removal devices use wheeled loaders (including wheel loaders, backhoe loaders, and skid steer loaders) or trucks as the main engine to perform fast-moving mechanical snow removal operations, which are usually removed with ordinary buckets. Bucket teeth, adding a blade or using an integrated snow pusher as a snow removal device to shovel or push snow, but there are problems such as easy damage to the ground, poor adaptability to local unevenness of the ground, and easy damage to the blade or snow pusher , and even cause the deformation of the structural parts of the main engine car body, affecting the normal use of the whole machine

At present, even specialized snow removal devices have problems such as low reliability, poor obstacle-crossing ability, and low single-time push snow volume.
