Description

one

The invention relates to agricultural machinery and can be used for processing mainly sown or sown soils.

A known machine for loosening and fertilizing sodden soils, including a rolling cylindrical tank with syringes and syringes, equipped with a device for distributing the working solution to the needles.

This machine does not loosen the soil in the area of the root system and the flow of liquid-gas suspensions into the soil, and the needle syringes in the process of their movement turn the soil and injure the plants.

The purpose of the invention is to feed the working solution into the soil in the form of a liquid-gas suspension.

This is achieved by the fact that in the proposed machine the device for distributing the working solution is made in the form of a fixed body mounted on the tank axis, having channels communicating with the tank and a gas source, and a movable sleeve with holes alternately communicating the body channels the surface of the tank and made respectively for the liquid and gas collectors connected to each other and

with needles jet ejectors. The collectors are hinged on the side surface of the tank and equipped with a mechanism for controlling needle trajectories made in the form of a crankshaft connected to the collector and rolling in a fixed guide roller, and a spool device built in, for example, electromagnets.

FIG. 1 shows the proposed machine, side view; in fig. 2 - schematic diagram of the maschina, cross section.

It contains a frame 1, a compressor 2, a receiver 3, a transport wheel 4 with a hydraulic cylinder 5, a cylindrical tank 6 (see Fig. 2) with supporting wheels 7, a hollow axle 8 with a side 9 and a receiving device 10,

a distribution device comprising a housing 11 with channels 12 and 13, a sleeve 14 with two rows of holes and flexible hoses 15 and 16 for liquid and gas, as well as manifolds 17 in a block with syringe needles 18 and

jet ejectors 19. The collector at one end has a connection with flexible hoses, and at the other end - a crank with a roller 20, which interacts with the guides 21.

The spool device 22 is built into the line of the gas manifold 23. The maintenance of a constant pressure in the reservoir is achieved by means of a gas pressure regulator 24.

In the working position, the machine does not roll back up the support wheels 7 of the cylindrical tank 6. In this case, the syringes, turning together with the gas-liquid manifolds according to a predetermined trajectory of movement, are inserted into the soil. The liquid is supplied to the corresponding reservoir cavity immediately before the needle-syringes are dug into the soil, and the gas is supplied during the process of deepening. Fluid is supplied from the reservoir through the receiving device 10, the hollow axis 8, the channel of the fixed body and the holes through the hoses to the collector bed. Regulation of the amount of fluid supply is provided by maintaining a constant pressure in the tank, achieved by means of a gas pressure regulator, and a throttle device 25.

When needle needles move in the soil, gas from the receiver under high pressure is pulsed by the flow of the spool through the switchgear device into the gas cavity of the collector and, passing through the jet collectors, carries the solution and sprays it. Through the holes in the syringe needles, the liquid-gas suspension is injected into the area of the root system, enriches it and loosens due to soil vibration due to the pulsating gas pressure.
