Description

Shovel sweeping and throwing combined snow remover

Technical Field

A combined snow remover for shoveling, sweeping and throwing belongs to the field of environmental sanitation machinery and snow removing machinery.

Background

In the snow removing process of the urban road, the snow and ice on the road surface need to be cleaned, and the cleaned snow and ice loading vehicle is transported to an outing snow-accumulating site or a garbage yard, so that the snow is prevented from occupying the road, the road of the urban road is ensured to be smooth, and traffic paralysis is avoided. In addition, in the snow removing process, a snow melting agent is generally required to be thrown to the road surface, so that the situation that the accumulated snow on the road surface is compacted by vehicles to cause hardening and difficult cleaning is avoided, the ice and snow surface of the hardened road surface is smooth like ice, traffic accidents are easily caused, and the situation is not allowed, and the ice and snow spread with the snow melting agent can cause great damage to greening trees on the two sides of the road and bridges and must be transported away. The road ice and snow cleaning work since 2006 gradually changes the previous way of sectionally wrapping and drying along each street unit, and each unit organizes a manual cleaning method by self, and mechanical snow cleaning work is adopted successively. Through the development and progress of snow removing machines for over ten years, the current road ice and snow cleaning work generally adopts a five-step method operation mode: the first step is as follows: spreading a snow-melting agent; the second step is that: the rolling brush sweeps the accumulated snow on the road surface to the road side, if the accumulated snow on the road surface is thick, the rolling brush is used for sweeping the accumulated snow on the road side, a plough type snow remover is used for shoveling once, a large amount of accumulated snow is piled to the road side, and then the rolling brush is used for continuing sweeping until a black road surface is exposed; the third step: using a loader to collect snow on the roadside into a large snow pile, and then loading the snow pile in a face-to-face shoveling mode by using two loaders; in other places, the rolling brush is used for sweeping snow belts on the roadside, firstly, the snow belts are formed into snow ridges by a ridging machine, and then the snow ridges are thrown into a self-discharging carriage for carrying snow out of a city by a snow throwing machine. The fourth step: manually cleaning the snow bottom left after loading by a loader or a snow thrower, namely manually cleaning the snow bottom; the fifth step: and (4) carrying out secondary loading, namely loading the accumulated snow which is manually cleared out again to the suburb. In the above operation mode, the link that the round brush cleaned, it is very fast, in the place that the round brush was equipped with sufficiency, can reach basically: the snow stops on a visible black road surface, but the speed of the loading link and the subsequent bottom cleaning link is very slow, so that the snow piles and snow belts can not be transported away in a long event on the roadside. The phenomena of traffic jam, tree damage and road and bridge damage occur in every large snow field. In the technical improvement process of continuously exploring a loading link, a plurality of improved technical schemes are provided according to the existing operation mode and the existing mechanical variety, but the method mainly adopts a method of simulating the working mode of the existing loader or snow thrower, pushing a bucket forwards, enabling ice and snow on the road surface to enter the bucket, installing a secondary conveying machine in the bucket, and conveying and lifting the ice and snow entering the bucket backwards so as to finish the loading work. According to the technical scheme, a group of cleaning mechanisms are additionally arranged behind the bucket, and the cleaning mechanisms clean the thinner ice and snow left in the process of pushing the bucket to shovel the snow again and then lift and load the snow again through another group of conveying mechanisms. For example: the application numbers are: 2009200930880, 201110178051X, 2013107106125, 2004100438328, 201420688429X, and the like. The technical proposal generally selects the proposal which is improved by imitating the existing snow removal mode that a bucket which is opened forwards is pushed forwards by the existing loading machine, the ice and snow entering the bucket are conveyed and lifted backwards, which is in accordance with the thinking law of people, namely, the proposal is improved aiming at the existing and in-use machine, and the thinking and the improved method are also the routine choices of the technicians in the field. In the patent of the applicant filed on the same day, there are several patent application documents which can remove harder ice and snow, then clean the road surface by rolling, and then lift and load the ice and snow to high places by the same conveying machine, but for courtyard snow removal work of offices, enterprises and institutions, and small areas such as pedestrian footpaths and narrow roads, large-scale machines are difficult to enter into the work, vehicles which are required to transport ice and snow are also small, even with a trolley, when snow is transported by a low-level vehicle, large-scale snow removal vehicles which are filed on the same day are difficult to play a role, a small-scale snow removal device which can load snow to small-scale snow transportation vehicles is needed, snow transportation vehicles are also required to be in front for snow removal work such as sidewalks and narrow roads, and the snow removal device cleans the ice and snow from the back and loads to the front vehicle, thereby determining the technical problem to be solved: firstly, what kind of mechanism can be used to remove hard snow on the road surface. Secondly, the snow and ice sent by the hard snow removing mechanism and the rolling brush which have two working parts with different functions must be simultaneously loaded on a snow carrying vehicle, so that different parts are organically combined and work in cooperation, and the structure is the most exquisite. And simultaneously determines the technical effects to be realized: firstly, the method comprises the following steps: the hard snow can be removed. Secondly, the road surface is swept clean. Thirdly, the method comprises the following steps: the removed hard snow and a small amount of accumulated snow remained on the road surface when the hard snow is removed must be loaded on the snow carrying vehicle at the same time, and the snow and ice which are cleaned by rolling brush are not allowed to sweep to the road side and are not loaded. Fourthly: the obstacle avoidance function is strong, and the snow removal speed is fast. Fifth, the method comprises the following steps: the mechanism is simplest and the components used are minimal. For a new snow removing machine capable of solving the technical problems and achieving the technical effects, the applicant has named it: a shovel sweeping and throwing type combined snow remover adopts the technical scheme as follows.
