Description

(54) SNOWFISHER

one

The invention relates to a device m intended for clearing snow from pavements, namely, mobile machines for cleaning snow and snow containing foreign inclusions.

Known snowballs containing a self-propelled chassis on which a screw feeder, a conveyor, a heat generator and a smelting bath with a fender bar, a water discharger, a crusher, an intensifier and an inclined chute installed between the fender bar and the intensifier are installed on it.

The disadvantage of this snowfall is the inability to clean the snow bath from foreign inclusions contained in the snow during the continuous snow removal.

The closest to the invention is the snowcladder, containing, and the base chassis, installed on it is a melting bath with a sand collector and a heat generator 2.

The disadvantages of this snow lick are the unreliability of the work of the gate, when it comes in contact with the bath because of the possibility of it falling under it: they are in the sludge

items. In addition, the process of cleaning the sand collectors by means of a membrane and vibrators with this sand collector design requires the participation of manual labor. The purpose of the invention is to increase efficiency by simplifying the removal of sand and sludge.

The goal is achieved by the fact that snowballs are provided with vertical guides fixed in the Q bath, rollers fixed on the sand collector and mounted on the tracks, while one of the walls of the sand collector is hinged at its base, and holes are made in the walls of the sand collector.

15 In addition, the snowballs are provided with locks fixed to the base of the sand collector for fixing the wall hinged to it, and stops fixed to the vertical guides for

20 interacting with locks, additional stops fixed on the upper ends of the vertical guides, and on the hinged wall of the sand collector, protrusions are made to interact with these guides, and it is also equipped with a swivel tray hinged at the top of the melting bath with the possibility of interaction with sand collector. FIG. 1 shows a semi-stationary snowfall of the species, general view; in fig. 2 — melting bath, section A-A in FIG. 1. The snow maker is made in the form of a semi-trailer and contains a welded structure mounted on the base 1 melting bath 2 of welded construction, a burner 3 for heating water in the melting bath 2, a power plant 4, which is a diesel-electric unit, and a control cabin 5. For Snow loading into the snow melting bath 2; a snow loader is used, which is a conveyor 6 with a hopper (not shown). The body of the burner 3 is made of heat-resistant steel and is attached to the melting bath 2 in such a way that the lower part of the burner 3 is submerged in water during operation. To improve the heat exchange between the combustion products and water, as well as to create airlift, the lower part of the burner 3 is placed in a cylindrical case 7 having a window (not shown). To maintain the level of water in the melting bath, a vertical drain 8 is arranged. In the lower part of the melting bath 2 there is a special valve 9 for draining water and two hatches 10 for cleaning the bottom of the melting bath 2 from sand and dirt leaking from the sand collector. The walls of the bottom of the smelting bath 2 form a channel 11 for the exhaust gases of the power plant 4. In the lower part of the smelting bath 2 on cables 12 a sand collector 13, representing a welded bunker with a sloping bottom (45 ° and more) and a wall 14, is pivotally fixed to bottom and locking locks 15. On the side walls of the sand collector, three rollers 16 are mounted on the axles, sliding along cylindrical guides 17 mounted vertically inside the melting bath 2. The drive of the sand collector 13 is driven by a driving drum (not shown) with a polis 18. In the upper part of the melting bath 2, the rotary chute 19, made in the form of a sheet with stiffening ribs, is hinged and serves to prevent foreign inclusions from the sand collector 13 from falling back into the melting bath 2. To tilt the rotary chute 19 from the neutral position to the working position when the sand collector 13 moves upward, at least one of the edges of the cantilever end of said tray 19 is fixed with a wedge-shaped element 20, intended for. interaction with the upper edge of the sand collector 13. There is also a fixed guide chute 21. On the upper part of the rails, stops 22 are installed to force the locks 15 to open and additional stops 23 to tilt the front wall 14 of the sand trap 13. In the side walls of the sand collector, holes 24 are made to drain water when lifting the sand collector 13 and for filling it with water when lowering into the smelting bath 2. Such a snow construction allows the work to be carried out with significant contamination of snow (up to 10% of foreign matter). Snegot lka works as follows. A vehicle (dump truck, etc.) unloads snow into a hopper (not shown), from which snow is transported through conveyor 6 into a melt bath 2, into which water is pre-filled to the level of the upper edge of a drain 8. Water is heated by burner 3. When the burner 3 is in operation, an airlift is created that raises water into the space between the burner 3 and the cylindrical casing 7 and intensifies heat exchange between the combustion products and hot water. through a special window (not shown) in the cylindrical housing 7 of the burner 3 to the snow loaded into the melting bath 2, as a result of which the snow melts. The melting process is intensified by creating a relative velocity between the snow and water due to bubbling that accompanies the operation of the burner 3 of the submersible type. Foreign inclusions (sand, dirt, stones, etc.) contained in the snow are deposited with and accumulate in the sand collector 13. When the sand collector is filled with 13 sand and debris, the sand collector 13 is lifted along the drive drum and tackle 18. 17 above the melting bath 2. When lifting, the water in Sandbag 13 is poured back into the melting bath 2 through holes 24 in the side walls of the sandbag 13. Moving upwards, the sandbag 13, as a result of the interaction of its upper edge and the wedge-shaped element 20 , tip pivoting chute 19 into working position, and with further movement of the sand collector 13 upward the lower stops 22 installed on the guides 17 interact with the loops of the locks 15 located on the side walls of the sand collector 13, open the locks 15 of the front wall 14 of the sand collector 13. Stops 23 placed on the rails 17, interacting with the counter lugs located on the front flap of the sand collector 13, the flap front 14 of the sand collector 13 is pushed up, resulting in foreign objects, accumulated in the sand collector 13, the rotary and fixed guide trays 19 and 21, respectively, are discharged directly into the vehicle. When the sand collector 13 reaches the uppermost position, the sand collector body 13 actuates a limit switch (not shown), thereby stopping the movement of the sand collector 13 upwards. When moving the sand collector 13 down there is a consistent lowering of its front wall 14 to its original position, followed by locking it with locks 15, as well as the installation of the rotary chute 19 to its original position. When the sand collector 13 is lowered into the melting bath 2, the water in the melting bath 2 through the holes 24 in the side walls of the sand collector 13 fills it, which prevents the sand collector 13 from ascending. The economic effect of the proposed snowball is provided by increasing reliability and ease of removal. sludge and eliminate the need for participation in this operation manual (when removing items that fall into the gate of the famous snowballs).
