Description

one

The invention relates to the maintenance of urban roads in winter.

The purpose of the invention is to reduce energy consumption and increase reliability.

Fig, 1 schematically shows a bulk material spreader, side view} in Fig. 2, section A-A in Fig. 1; on (jMr, 3 - section in figure 1,

 The bulk material spreader consists of a bunker 2 with inclined side walls mounted on a self-propelled chassis 1, in the back part of which a vertical conical pipe 3 is installed, inside which is placed a dispenser in the form of a conical screw 4 connected to the drive hydraulic motor 5 by means of a bevel gear 6, mounted inside the vertical flow of the conical pipe 3, and the output end of the latter is made in the form of a guide nozzle 7 in contact with the guide tray, nnym a valve 8 mounted pivotally on the axis 9 and the spring-loaded relative to the guide nozzle 7, the compression spring 10.

A scattering disk 12 is fixed to the rear of the vertical conical pipeline 3 in the bearing support 11, the drive shaft 13 of which is connected to the hydraulic motor 14 through the gearbox 15, Driven gear 16 of the gearbox 15 is connected to the drive shaft 13 by means of a sliding puffy joint, thus the transmission of torque to the spreading disc 12 is not interrupted by the axial movement of the shaft 13,

Changing the position of the spreading disc above the road surface is carried out by means of an actuator 17, the brush of which is connected to a pulling ring 20 fixed to the drive shaft 13 via shackle 18 and cams 19. The spreading disc 12 is raised and lowered by transferring force from the cams 19 ring stop 21 t beef ring 20,

Inside the hopper 2 mounted cylindrical rollers 22, Supports

063602

rollers mounted in bearings 23 installed in the side walls of the hopper, and the rollers 22 are placed in a plane oriented at 5 angle to the horizon with a bias towards the feed vertical conical pipe 3, and on the surface of the rollers 22 is mounted an infinite elastic band 24,

10 performing the function of the movable bottom of the hopper 2,

The bulk material spreader works in a consistent way. Before the beginning of the distribution of

(5 pulling the material using the power cylinder 17 sets the spreading disc 12 relative to the valve 3 to a position corresponding to a given dressing width. When the stem of the power cylinder 17 rotates, the link 18 connected to it moves, which through the cams 19 and the pull ring 20 acts on the rotating shaft shaft 13,

25 Owing to the running fit, the splined end of the shaft 13 passes through the driven gear 16 of the gearbox 15, which continuously transfers torque to WAD 13,

30 A higher position of the spreading disc 12 corresponds to a wider spreading width.

After installing the spreading disc 12 include the course of the base

 The chassis I and at the same time drive the conical auger, which rotates, seizes material and forces it through the guide nozzle 7 of the feed vertical conical pipe 3, the functional purpose of which is to form a compact jet of technological material. As the material moves to the guide nozzle 7, it is compacted by the tapering walls of the vertical conical conduit 3. In this case, lumps of material, always contained in the total mass, deteriorate.

50 quality of road dressing,

A dense stream of material coming out of the pipeline, bends the valve 8, which is spring-loaded relative to the whole nozzle 7,

55 and hits the rotating disc 12.

As the bulk material is consumed, its mass is

above the feeder, decreases, freeing the volume of the bunker 2 in its rear part. At the same time, the mass of material lying on the belt 24 will move together with the belt 24 towards the released volume of the bunker 2. This

the process of moving material from

The front of the bunker 2 to the rear occurs automatically as the volume in the rear of it is released until the bunker 2 is completely unloaded.
