Description

The utility model relates to agricultural machinery, in particular to combined machines for cultivating tall crops.

A known unit for the care of tall crops [Copyright certificate RU patent No. 1724040, IPC class. A01B 59/04, A01D 46/28, 1992], consisting of a tractor and a tillage implement mounted on it, containing an arched frame on which mounted working bodies of a rotary type, gearboxes, a support self-aligning wheel and a linkage mechanism in the form of a triangular frame.

The disadvantage of this unit is the insufficient copying of the soil relief by the working bodies and the lack of the chemical protection function of plants by spraying.

The closest analogue to the claimed is the unit for cultivation of high-stalk crops [Copyright certificate RU patent No. 1794335, IPC class. А01В 59/04, А01В 59/06, А01В 39/16, 1993] including a tractor, an attachment and a tillage implement with an arched frame, the working bodies and supporting wheels of which are mounted on a frame, one of which is mounted on the arched frame, and the other on the attachment.

The disadvantage of this design is the lack of chemical protection of plants by spraying.

The technical result of the utility model is the emergence of a new function of chemical protection of plants by airborne spraying.

The technical result is achieved due to the fact that the arched frame is made in the form of a pipe muffled from below with holes on the inner side of both arms, in the upper inner part of which an axial fan is installed, with the possibility of powering from the tractor electrical system, and opposite to the holes on the arm of the arch closest to the tractor sprayers with the ability to connect to a tractor mounted sprayer.

The specified set of essential features ensures the appearance of the inventive unit for cultivating high-stem crops with new properties that are different from the prototype.

Thus, the claimed features of the utility model meet the criterion of "novelty."

In FIG. 1 is a schematic diagram of an aggregate explaining its operation, front view.

A unit for cultivating high-stalk crops, including an attachment in the form of a beam 12, mounted by means of a longitudinally horizontal hinge on the side of the tractor 8 and controlled by a hydraulic cylinder 10, an arched frame 4, one end of which is fixed to the hinged device by means of a longitudinally-horizontal hinge, milling tools 1 s driven by hydraulic motors 3, powered by a hose 11 from the tractor hydraulic system, mounting frames of working bodies 2 with backup wheels 13, characterized in that the arched frame is made in the form of a pipe muffled from below with holes 5 on the inner side of both arms, in the upper inner part of which an axial fan 6 is installed, with the possibility of power supply from the tractor electrical system, and sprayers 7 are installed opposite the holes on the arch arm closest to the tractor and can be connected to the tractor mounted sprayer 9.

The work of the unit for the cultivation of tall crops is as follows. Before work, the proposed unit and, mounted with the tractor used, the mounted sprayer without a serial boom are hung on the tractor. The sprayer line of the unit is connected to the discharge line of the sprayer instead of the boom, the fan to the tractor electrical system, and the hydraulic motors to the tractor hydraulic system.

The spraying system of the unit is adjusted to the application rate of pesticides by a known method.

The tractor driver enters the aisle of raspberries, saddles a row of plants with an arch, includes a drive of milling working bodies, a fan, a sprayer pump and starts the movement of the unit.

When moving, milling working bodies cultivate the soil in the near-mouth zone on both sides of a number of cultivated plants, copying the relief with support wheels.

At the same time, atomizers mounted on an arched rod create dropping torches along the entire height of the plants. Drops falling into the air stream created by the fan from the openings behind the nebulizers are further crushed. The resulting airborne droplet actively penetrates the vegetative part of cultivated plants, providing the required coating density with drops of the upper and lower parts of the leaf surface. The part of the drops that have not settled on the plants is absorbed through the holes on the opposite shoulder of the arch and is involved in a further circuit.

Such a work process allows one-pass processing of soil in the near-mouth zone on both sides of the row and simultaneous air-drop spraying of high-stalk crops, increases the rate of deposition of drops on the target processing object and reduces the loss of pesticides into the environment, bringing a significant economic effect.
