Description

Large-scale spiral auger snow pressing device Technical Field The invention belongs to the technical field of snow compression equipment, and relates to a large spiral auger snow pressing device. Background In snow clearance operation in winter, especially the large tracts of land snow scene such as town road, large-scale square, ski resort, highway, snow clearance and the efficiency of transportation directly influence traffic safety, public environment guarantee and relevant operation cost. At present, the problems of low snow density, fluffy state and high viscosity of the snow generally exist in the existing snow cleaning operation, and even if the snow is collected through preliminary cleaning, the snow is still in a loose state, so that the actual loading capacity of a transport vehicle is greatly reduced, and the rated volume of the vehicle cannot be fully utilized. In order to complete the snow clearance task, the transport vehicle needs to frequently go back and forth between the snow collection point and the dumping point, so that the operation cost of fuel consumption, vehicle abrasion and the like is increased, the snow clearance operation period is prolonged, the overall operation efficiency is reduced, carbon emission is increased due to frequent back and forth, and the industry development requirements of energy conservation and emission reduction are not met. In the prior art, a part of snow compression device adopts a simple spiral conveying structure, can only realize the conveying function of snow, cannot effectively compact the fluffy snow, or has poor compacting effect, is difficult to obviously improve the snow density, and in addition, the part of snow compression device does not consider the difficult operation problem in a low-temperature environment, snow is easy to freeze at low temperature in the conveying process, adheres to the inner wall of the barrel of the device, so that the snow accumulation is not conveyed smoothly, the device is blocked, frequent shutdown and cleaning are needed, and the operation continuity is further influenced. In addition, the structural design of partial snow pressing device is unreasonable, and drive part and supporting part are out of order, easily receive snow, moisture erosion, lead to equipment trouble to frequently send out, and maintenance cost is high, and can't adapt to heavy load, the continuous operation demand of large-scale snow clearance operation. Disclosure of Invention The invention provides a large spiral auger snow pressing device which solves the problems in the background art.
