The invention relates to road facilities and road machines when working on the spreading of anti-icing bulk materials (sand, granite chips, anti-icing agent), as well as for the transport of various building materials and goods (sand, crushed stone, asphalt, bulky cargo). The proposed device is distinguished by the fact that the forward side tilted at a certain angle backward is movable along the bottom of the body-bunker. Moreover, the bottom and side walls are made with the possibility of heating the exhaust gases of the internal combustion engine of the vehicle. There is also a grid for sifting the feed material on top of the bunker body, which has a deflection inside the bunker body and is also equipped with driving devices, mainly hydraulic cylinders, which allow it to be tilted to the side to ensure loading of non-bulk materials and bulky cargo directly into the bunker body without sifting. The drive conveyor is located across the body-bunker along the tailgate from the inside, and for the dump truck mode, the tailgate has the ability to fully open due to the drive devices, mainly hydraulic cylinders mounted on both sides of the tailgate, while the spreading device is mounted outside on the tailgate from below to move along with it. The drive conveyor can be made in the form of a screw with the opposite direction of winding of screw turns in its two halves for feeding bulk material to the center of the back side in the tray to the spreading device in the form of a disk. The drive mechanism for moving the front side can be made in the form of a double-acting power cylinder with a one-sided telescopic rod fixed by a hinged end of the cylinder on a fixed front beam of the base chassis immediately behind the driver’s cab, and hinged on the end of the stem on the front end power beam, and is located in the space between the driver's cabin and the front side of the body-bunker.

The dump truck installation for transportation of granulated material contains a bunker body 1 mounted on the base of chassis 2, cab 3. Each compartment of the bunker body 1 is equipped with an adjustable hydraulic gate valve, and there is a common shut-off hydraulic gate valve for unloading. From the first compartment through the second and third compartments goes through the duct 4, which is connected to the compartments by movable dampers, through which the granulated material is released. The outlet box 4 is equipped with a hydraulic flap 13 (gate valve). The roof of the bunker body 1 is equipped with hatches 5 of manual opening. For safety and convenience of personnel movement, the upper platform of the bunker body is equipped with transition bridges 6, both between the hatches 5 and the edges of the bunker, and are equipped with folding handrails-fences 7. The platforms have a grooved surface with anti-slip effect. For the convenience of lifting onto the roof of the bunker body, a folding ladder 8 is fitted. At the rear of the bunker body there is a removable discharge chute 9 made of plastic material.

Lifting and tilting of the body-bin to the required angle is carried out by means of a hydraulic lifting telescopic cylinder, equipped with a hydraulic lock and a lowering control valve. Tipper body-bunker 1 is equipped with a hydraulic bunker lift limiter connected to the bunker body with a cable. The device has a stable position on the surface of the cluster pad when working with a raised bunker thanks to four movable hydraulic supports 10 (outriggers with thrust bearings) located in the front and rear parts of the body, outrigger extension occurs simultaneously, the full extension / retract is determined by the pressure gauge.

The hydraulic cylinders are controlled using hydraulic distributors 11 and 12 located on the left side of the car, the first behind the cab to control outriggers, the second to control all cylinders on the left side of the car at the rear.

The dump truck installation for transportation of granulated material has an external control panel located in the rear part of the installation in a moisture-proof box on the right, an oil tank with heating due to engine coolant, an electronic inclinometer with an external sensor and a lift-lock valve, an emergency manual lowering crane. Moreover, a 700-liter fuel tank is located on the right side of the car, and a stainless steel toolbox is located on the left side of the unit. The installation is additionally equipped with spotlights in the rear part of the bunker to illuminate the receiving funnel, and for ease of operation, the dump bin is equipped with lighting of the bunker compartments, loading dock and outrigers.

Installation of dumping for the transport of granular material works as follows.

A car with this dumping installation, empty or previously loaded bulk material (hereinafter, the operation of the device is considered on the example of proppant transportation) is set at the receiving bunker. Outriggers with wooden feet are set and the car leveled. The alignment of the body takes place with the help of an electronic inclinometer. The required volume of proppant is loaded in sections. Having loaded the proppant into the dumping unit, the tester readings are checked. Before the start of work, the dump truck rises by 15 degrees, which corresponds to two fully extended rods of the hydraulic cylinder for lifting the body. The extension of the third rod of the hydraulic cylinder is limited by the maximum pressure in the hydraulic system to eliminate excessive loads on the rear outriggers and maintain a stable position.

The recommended order of opening the flaps occurs in the following order:

1. Flap of the first compartment

2. The second compartment flap

3. Damper of the third compartment.

By means of the general gate the feed rate of proppant is regulated.

Open the flap of the first compartment and fill the funnel auger to the maximum, waiting for the command to apply proppant. The operator begins to work with a common valve, placing the opening in such a position that the proppant level is maintained in the funnel, respectively, the formation of a proppant increases constantly during hydraulic fracturing, and the operator must constantly open more and more common valve. When visually the flow of proppant from the front compartment weakens, the operator raises the body to an angle of 30 degrees, thereby dropping the entire proppant closer to the total damper. Further, if the level of the proppant in the auger receiver begins to decrease, the operator closes the common damper by half and opens the second compartment dampers and continues to regulate the proppant feed. In the same sequence, the third compartment is unloaded with the help of dampers. After dumping the entire load, the body is lowered. After all the work is completed, the body supports (outriggers) are raised, the slide gate is pushed and lowered.
