Description

SNOW CLEANING DEVICE

The proposal relates to the field of maintenance of roads and is intended for the effective removal of snow from them.

The closest known one is a self-propelled snow removal device, in which snow picked up from the road by a belt elevator is fed through a hatch into a container heated by hot furnace gases and engine exhaust gases, in which snow melts and then accumulates the resulting water, for example, in a trailer to the device tank and draining it into the sewage wells (SU patent

No. 7313, 1928).

The known solution does not provide sufficient intensity of the snow removal process, since it requires periodic movement of the entire snow blower with a trailed tank to the drain point of melt water, which also requires additional material costs and additional time for this process. In addition, the issues of ensuring the environmental cleanliness of the snow removal process, which traditionally contains, especially in urban conditions, the inclusion of foreign objects, such as plastic and glass bottles, plastic bags, etc., have not been resolved. The snow removal process itself, despite the progressive technology that ensures the highest possible

filling the transport tank not with snow having a sufficiently low density, but with melt water, which provides at least a five-fold increase in the useful use of the volume of the transport tank, still requires the creation and use of special equipment that excludes freezing of melt water during transportation and discharge. Such special equipment can only be used for the period of seasonal snow removal work, which casts doubt on its profitability.

The objective of this technical solution is to increase the efficiency of snow removal while intensifying the process of its disposal, reducing the number of vehicles involved in the snow removal process, reducing material costs and ensuring the environmental cleanliness of the process.

This is achieved by the fact that the device for snow removal contains a self-propelled snow loader and a transport heater that is heated with a loading hatch and an unloading device, for melting the loaded snow and subsequent transportation of melt water to the discharge site, while the transportable heated tank is insulated, has heat pipes and is located in its cavity is an agitator, preferably of a reverse action, for distributing the loaded snow and intensifying the process of its melting and is mounted on a frame of a self-propelled conveyor mercury means, preferably connected for the period of snow loading by a rigid coupling with a self-propelled snow loader, with the possibility of tilting the heated container towards the discharge device when unloading melt water and / or foreign objects contained in it. In the device, the reverse-acting mixer can be kinematically connected with the drive of a self-propelled vehicle or with an autonomous drive and equipped with a means for changing its rotation speed. For

filtration in the process of mixing melt water with snow and unloading the tank by removing melt water from it can be installed means for filtering melt water. As a self-propelled vehicle containing a heated transport tank with a loading hatch and an unloading device, an agitator, preferably of reverse action, a device for transporting, preparing and unloading a thermoplastic material, for example, asphalt, can be used.

The technical solution is illustrated in the drawing, which shows a diagram illustrating the General view of the device for snow removal (dotted line indicates the position of the discharge of the tank);

The snow removal device comprises a self-propelled snow loader 1 and a heated transport tank 2 with a loading hatch 3 and an unloading device 4, for melting the loaded snow and subsequent transportation of melt water to the discharge site. The transportable heated container 2 is thermally insulated, has flame tubes and a mixer located in its cavity (not shown in the drawing), preferably of reverse action, for distributing the loaded snow and intensifying the process of its melting. The heated transport tank 2 is mounted on the frame of a self-propelled vehicle 5, preferably connected by a rigid hitch 6 with a self-propelled snow loader 1 for the snow loading period. The tank 2 is mounted with the possibility of its inclination (the inclined position is shown by a dotted line) in the direction of the unloading device 4 when unloading melt water and / or foreign objects contained in it. In the device, the reverse-action mixer is kinematically connected with the drive of the self-propelled vehicle 5 or with an independent drive and is equipped with a means for changing its rotation speed. For filtration in the process of mixing melt water with snow and unloading the tank by

removal of melt water installed means for filtering melt water. As a self-propelled transport vehicle 5 containing a transportable heated tank 2 with a loading hatch 3 and an unloading device 4, an agitator, preferably of reverse action, it is advisable to use a device for transporting, preparing and unloading thermoplastic material, for example, cast asphalt, which reduces the need for transport vehicles snow and provides effective all-weather use of special equipment.

In the process of operation of the device for cleaning directly at the place of cleaning, the snow loader 1 is loaded into a heated insulated tank 2 mounted on a self-propelled vehicle 5 connected by a rigid coupling 6 to the loader 1 for the period of snow loading. By heating the walls of the tank 2, at least part of the snow melts and is unloaded from the tank 2 by removing melt water and wetted snow from it through the unloading device 4, which has, for example, a heated sleeve or a tray. Simultaneously with the process of snow melting, the self-propelled vehicle 5 is moved and the snow is mixed with melt water with a mixer, which rotates reversely relative to the axis longitudinally located in the tank. The tank 2 is loaded with snow until it is filled with melt water or a mixture of melt water with wet snow. Before mixing snow with melt water, the optimal speed of rotation of the paddle mixer for a given density of loaded snow is established taking into account the intensity of loading the tank with snow. In the process of mixing snow with melt water, melt water is filtered and circulated in the cavity of the tank 2. To remove melt water and / or wetted snow, the tank 2 is installed with an inclination towards the discharge device. Soaked in thermally insulated

Snow containers are sent for further heat treatment to a stationary snow melter. The melt water heated in a thermally insulated container is filtered through a discharge device. The objects remaining after filtration in the container are unloaded. Such organization of snow removal works allows to reduce the amount of equipment used for cleaning, to intensify the process, optimizing the loading of vehicles and ensuring high environmental cleanliness of the process.
