Abstract

This invention relates to road cleaning machines in the winter season. The purpose of the invention is the expansion of technological capabilities. The working body of the snow and ice removal machine contains screw blades on which they are installed with the possibility of extension in the radial direction and are spring-loaded with the possibility of adjusting the rigidity of the tooth spring. When cleaning the snow, the teeth are sunk behind the forming augers, and to break the ice, they are pulled out. 4 il. .

Description

The invention relates to machines for road cleaning in winter.

The purpose of the invention is the expansion of technological capabilities.

FIG. 1 shows the device, a general view: in Fig. 2 - view A on fig 1; FIG. 3 shows a part of a screw feeder with spring-loaded teeth fixed on its edges; Fig. 4 illustrates the mechanism for adjusting the extension of all teeth.

The working body of the machine for removing ice from pavements contains a body 2 with driving gear mounted on it (Horizontal shaft 3 with auger blades 4, 5, on the edges of which there are cutting teeth 6 radially transversely rotatable damping in this direction. The tooth 6 is damped due to the fact that they are strung on the cables 7 and 8. The tension of which can change the degree of damping of the teeth. The cables 7.8 pass through the sleeves 9. fixed around the perimeter of screw db

mouths 4 and 5 are fixed at one end to them, and to the other through a spring 10.11 on the tension screw 12.13.

The tension of the cables 7, 8 can be measured by varying it by tension through the springs 10 and 11.

When the tension of the cables 7, 8 is relaxed, the springs 14 retract the teeth 6, subject to the tension of the cable 7.8, the teeth 6 move forward. With this, the stiffness of their fastening in the radial direction simultaneously increases.

The body 2 of the working body is equipped with a slide 15, pivotally mounted on the rods 16 of the hydraulic cylinder 17 and serving for the adjustable raising and lowering of the working body.

The device works as follows.

When snow is being removed, the tension of the cables 7.8 is weakened and the tooth 6 is sunk, not over the edge, of the screw blades A, 5. When the base machine 1 moves, the screw blades 4.5. transporting snow on the blades

18 of the rotor 19, which removes it to the conveyor 20 and further to the vehicle (not shown).

When cleaning the ice, the cables 7–8 pull in and the tooth 6 extends from the edge of the auger blades 4, 5. By means of the hydrodynamic drill 17, the body 2 of the working body is lowered

When the base machine 1 moves, the teeth alternately and symmetrically with respect to the middle of the body 2 crash into the ice shell, breaking off pieces of ice from it, which are transported by blades 4, B to

the rotor 19 and the conveyor 20 in the vehicle.

Formula of the invention The working body of the machine for removing snow and ice from pavements, containing a horizontal drive shaft with a screw blade, on the edges of which are placed a cutting tooth, distinguished by the fact that, in order to expand technological capabilities, the teeth are mounted with the possibility of moving radial direction and spring loaded with the ability to adjust the spring stiffness in the specified direction.
