Description

The invention relates to vehicles with high cross-country ability using an air cushion, to mining in the reclamation of disturbed lands, to peat extraction to reduce peat losses from getting wet, especially in areas with adverse climatic conditions and other areas of the national economy.

A vehicle for collecting bulk material is known, comprising a body, a cargo container, a pneumatic actuator with a rotating shaft, a looped pipe with nozzles for sucking bulk material communicated with a cargo container for collecting bulk material and a fence. (Patent 169496. Vehicle for dust collection. Published on March 21, 2017. Bull. No. 9. Authors: Davydov S.Ya., Semin A.N., Filatov M.S.; Patent 2613751. Vehicle of high cross-country ability. Publ. March 21, 2017. Bulletin No. 9. Authors: Davydov S.Ya., Cheremisina T.N., Kostyuk P.A.)

It is also known a vehicle for collecting bulk material, containing a body, a cargo container, a pneumatic drive with a rotating shaft, a looped pipe with nozzles made from its lower side for sucking and collecting bulk material, a stirrer and a fence. (Patent 169250. Vehicle for dust collection. Published on March 13, 2017. Bull. No. 8. Authors: Davydov S.Ya., Filatov M.S., Suslov N.M., Cheremisina T.N.)

Known devices are designed for lifting and suction of dust particles of bulk material and are not equipped with special mechanisms for turning and collecting bulk materials (peat particles) from the soil surface.

The objective of the development is to expand the area of use and increase the performance of the vehicle for collecting bulk material (peat particles) without additional energy sources.

The task is ensured by the fact that in a vehicle for collecting bulk material, containing a movable body, a cargo container, a pneumatic actuator with a rotating shaft, a looped branch pipe equipped on its lower side with nozzles for sucking and collecting bulk material, agitator and a fence, the looped branch pipe contains movable clamps equipped with swivel joints, on which a fence with a stirrer made in the form of brushes is suspended to ensure free lifting and lowering, mounted on a hollow rotating shaft, the cavity of which is connected by a bypass flexible hose with a discharge air duct.

The figure 1 shows a diagram of the proposed device; in fig. 2 – remote element of the agitator assembly.

The vehicle for collecting loose material (peat) contains a movable body 1 with a cargo container 2 for collecting loose peat. Due to the compressed air of the pneumatic drive 3, the movable body 1 moves along the peat area. The branch pipe 4, looped around the body 1, equipped with nozzles 5 on its lower side, is designed for suction and collection of peat. The peat agitator is made in the form of brushes 6, mounted on a rotating hollow shaft 7, which is placed in a hinged fence 8. The hinged fence 8 is hinged on the looped branch pipe 4 using clamps 9. The looped branch pipe 4 is connected to the bypass pipeline 10. The skirt 11 is installed around the body 1. The bypass pipeline 12 is made in the form of a flexible hose, which is designed to supply compressed air to the rotating hollow shaft 7. The clamps 9 are equipped with hinges 13, on which the casing 8 is installed. fences 8 vertically above the surface of the peat flooring. The rotation of the hollow shaft 7 is provided by compressed air flows coming from the discharge duct 14 through the bypass flexible hose 12.

The movement of a vehicle using an air cushion on peat fields, in comparison with wheeled and caterpillar vehicles, occurs without compacting the peat layer, especially its wet surfaces. When the vehicle moves, streams of compressed air escape from under the skirt 11, which stir, knock out and raise dust particles of peat from the peat surface. Rotating elastic cylindrical brushes 6 fixed on the shaft 7 create a loose layer of uniform thickness by milling the peat deposit. The rotation of the hollow shaft 7 is provided by compressed air flows from the pressure air duct 14, which enters through the bypass flexible hose 12. The free lifting and lowering of the brushes 6 vertically above the surface of the peat flooring is provided by the hinged 13 connection of the hinged fence 8 to the clamps 9. Peat is swept with brushes with a violation of the capillary connections with the deposit and the direction of the flow of peat crumbs towards the lower side of the nozzles 5. The nozzles 5 suck in and collect peat particles in the branch pipe 4 and are fed through the bypass pipeline 10 into the cargo container 2 to collect loose peat. The movement of the fence 8 along the surface of the looped branch pipe 4 occurs with the help of clamps 9 with the possibility of turning the agitator in the direction of movement of the movable body 1.

The main task of turning the collection of bulk material of milled peat is to intensify drying with technological requirements:

• creation of loose peat layer, uniform in thickness;

• milling of peat deposits;

• use of elastic cylindrical brushes;

• sweeping of peat with violation of capillary connections with the fallow.

According to the method of pile distribution, cylindrical brushes 6 are divided into brushes with a uniform pile distribution (brush discs) and uneven (separate sweeping elements). The process of active tedding is accompanied by crushing of large peat particles by 10-15%. With porous (loosened) spreading, favorable conditions are created for pneumatic harvesting of peat in the presence of a pressure difference that acts on particles with a certain lifting force.

Thus, the claimed bulk material collection vehicle performs collection and storage in a freight container. The technical result is to expand the area of use and increase the productivity of the vehicle for collecting bulk material (peat particles) without additional energy sources.
