Abstract

The invention relates to pressing devices, in particular to squeezing screw machines designed for briquetting snow from sidewalks, garden paths, central streets of the city. The technical result of the invention is to increase the degree of compaction of snow and to increase the utilization rate of transport capacity. the housing structure, which tapers in the direction of snow movement, also conical screws rotating in opposite directions from Yemen step spiral blades. Moreover, at the exit from the body there is a plate with a spring, which moves under the pressure of a snow briquette. To regulate the length of the briquette, a knife is provided located at a predetermined distance from the outlet of the housing of the snow-sealing device.

Description

The invention relates to pressing devices, in particular to squeezing screw machines designed for briquetting snow from sidewalks, garden paths, and central city streets.

Known snow-loading machine and a device for compacting snow, containing a base machine and an arrow with a conveyor, a thermal device is mounted along the entire length of the arrow (No. 28133, class E01H 5 / 00.10.12.2001) [1]. The principle of operation is that in the known device for compacting snow containing a housing in the cavity of which a screw is located and a nozzle attached to the housing, the latter is made in the form of a box with a rectangular outlet section, while the rear wall of the nozzle is made opening. The disadvantage of this design is that the weight of the additional device should not be more than 250-300 kg from the strength conditions of the snow loader boom. A single screw cannot provide thorough mixing to obtain uniform mass and density.

Known snow removal unit containing a hopper with a loading window, a chamber for pressing snow with a piston and a system for supplying coolant to the chamber (No. 37731, class E01H 5/00, 01/20/2004) [2]. The disadvantage of this design is that you need a lot of pressure to compress the entire volume of snow. When pressing snow with high pressures, the effect of “clogging” of gases in the pores arises and their further “pressing” occurs, which subsequently leads to defects in the finished briquette.

A device is known for sealing snow to a snowplow, consisting of snowplow manna containing a casing in the form of a parallelepiped and a pressing device (No. 60539, class E01H 5/00, published on 09/10/2006) [3]. The disadvantage of this design is that there is no mechanism that would regulate the size of the finished briquette.

Known snow compactor containing a body, a working body for snow compaction, made in the form of a lattice, a drive for moving the lattice and a rack in the body to control the vertical movement of the working body, the drive for the working body is made in the form of a vibrator, and the racks are based on elastic elements (No. 153025, class E01H 5/00, 02.24.2015) [4]. However, the known device has a significant drawback, namely, that this design is placed in the back of a transport vehicle and reduces the useful volume of the back.

Known snow loader for compaction of snow, consisting of a base machine, working bodies, a conveyor belt, snow compaction device and a thermal unit with a fan. The principle of its operation is that the body of the snow packer is made tapering in the direction of movement of snow (No. 301398, class ЕВВ 5/08, 11/28/1969) [5]. The above solution uses a paw snow loader designed for cleaning roads and highways, and constant, stream loading of snow is assumed. It has flaws. The auger is driven by a chain drive from a conveyor belt; its driven sprocket is located on the same shaft with the bevel gears, which makes it almost impossible to control the speed of rotation of the screws.

This technical solution is taken as a prototype of the proposed device.

The objective of the utility model is to increase the degree of compaction of snow and increase the coefficient of utilization of carrying capacity of vehicles.

The technical result is achieved by the fact that the body of the snow packer is made tapering in the direction of movement of the snow, but at the same time, by increasing the speed of rotation of the screws and an additional plate with a spring at the end of the body, it is possible to increase the density of the briquette.

It is preferable to choose an engine whose models can ensure reliable start-up and uninterrupted operation of equipment up to -30 ° C.

In FIG. 1 is a plan view; FIG. 2 is a sectional view of the apparatus, in FIG. 3 shows a fan with a casing.

The semi-trailed snow packer installation consists of a car trailer 1, a tapering body 2, in which a motor 3, a coupling 4, a worm gear 5, a bevel gear 6, augers 7, a loading hatch 8, a knife 9, guides for a plate 10, a plate with springs 11, are installed knife cutting mechanism12, slide gate for plate 13, groove 14, flashing light 15, fan16, casing 17.

The design described above works as follows. Snow is fed into the loading hatch 8, falls on the root of the screws 7, and is pushed by them. The snow is thawed due to exhaust gases from the motor 3, from which we take heat using the fan 16. And it is fed into the cavity between the body 2 and the casing17. The snow promoted by the screws is compacted by reducing the cross section of the casing and at the end of the casing presses on the plate with springs 11. The stiffness of the springs is selected so that there is no jamming of the screws. When the snow moves the slab to the extreme position due to the increasing volume, the slab will be automatically fixed by the slide lock 13. The flashing beacon 15 flashes and gives a signal that the briquette has reached the desired length. Having received the signal, the operator using the pedal activates the knife 9. The briquette falls on the gutter 14.

The advantages of the claimed semitrailer snow compaction installation: the creation of snow blocks convenient for loading and transportation, small dimensions and weight of the installation, low energy consumption, ease of manufacture, maintenance and operation.
