Description

The field of technology.

The claimed technical solution relates to the field of agricultural tools and is intended for tipping the root part of vegetable crops with previously loosened soil, as well as for treating inter-row spaces of crops with the destruction of weeds in them and planting fertilizers.

The level of technology.

Known adjustable disk hiller (Chinese patent for the invention of CN 105684572, IPC AB 13/02, 2016, [3]). As in the claimed technical solution, the hiller [1] contains symmetrically mounted discs.

In the analogue [1], each disk is connected to the L-shaped rod through the bearing housing. Left and right rods are made with the possibility of elongation and compression along their long holes, in order to change the distance between the two disks.

Known okuchnik disk (RF patent for the invention No. 2547923, IPC AB 13/02, 2015, [2]). As in the claimed technical solution, the analogue [2] contains spherical disks symmetrically mounted on racks with concave sides to each other.

The analogue [2] disks are installed with the ability to change the distance between them and adjust the angle of attack of the disks. Racks consist of two parts in the form of pipes of circular cross-section, entering one another with the possibility of rotation to adjust the angle of attack of the disks and with the possibility of axial movement with fixing parts of the rack in predetermined positions.

Known okuchnik (RF patent for utility model No. 41563, IPC AB 13/02, 2004, [3]). As in the claimed technical solution, the hiller [3] contains two, attached to the frame, symmetrically located, oriented to each other with the concave sides of the disk disc. Disks are mounted on supports. The axis of each of the supports is rigidly connected to the frame.

In analogue [3], the disks are configured to change the distance between them. At the same time, the distance between the disks is reduced, or vice versa, increased if a larger sleeve is installed in front of the sleeve with the disk.

As a prototype of the claimed technical solution adopted analog [3].

The technical problem, the solution of which is provided during the implementation of the technical solution, is the need to create a hiller structure that does not require adjustment. Such a hiller is used on the basis of the “install and work” principle.

Analogs [1-2] have a large number of movable and detachable connections of elements. This increases the preparation time of the hiller for work.

For the prototype [3], the hiller setup requires the use of measuring instruments and special tuning instructions. In addition, when the disk moves along the axis from the frame, a bending moment arises on the axis of the disk.

Disclosure of the essence of the technical solution.

The technical result provided by the claimed technical solution is to provide the possibility of using a hiller without adjusting the structure.

The essence of the claimed technical solution lies in the fact that the disk hiller contains disks, racks and a frame, while the disks are arranged symmetrically, and the racks are rigidly connected to the frame. It differs in that the disks are connected to the racks without the possibility of changing the angle and distance between the disks. The angles of the disks relative to the longitudinal axis of the direction of motion are α = 24 ° ± 5 °. In addition, the angles of the disks relative to the vertical in the working position are β = 18 ° ± 5 °.

In the particular case, each disk can be pushed to the rack using fasteners.

The author of the claimed technical solution made a prototype of this solution, the tests of which confirmed the achievement of the technical result.

A brief description of the drawings.

FIG. 1 shows a disk hiller (axonometric projection), FIG. 2 - front hiller, front view, in FIG. 3 - hiller disk, bottom view.

Implementation of a technical solution.

The Okuchnik disk (Fig. 1) contains disks (1), racks (2), a frame (3) and a hitch (4).

Disks (1) are mounted symmetrically. The angles of the disks (1) with respect to the longitudinal axis of the direction of motion are α = 24 ° ± 5 ° (Fig. 3). The angles of the disks (1) with respect to the vertical in the working position are β = 18 ° ± 5 ° (Fig. 2). When installing the disks (1) at these angles, an optimal cresting ridge is formed.

Disks (1) are attached to racks (2) without the possibility of changing the angle and distance between the disks (1). At the same time, each disk (1) is clamped to the rack (2) using fasteners.

The posts (2) are rigidly connected to the frame (3).

The coupling (4) is intended for connection with a tillage device or unit, for example, a walk-behind tractor.

The implementation of the proposed technical solution is not limited to the above example.

Work description.

The hitch hitch (4) is connected to a walk-behind tractor or other aggregate. When the assembled device moves, the disks (1) rotate and cover the fissures with vegetable crops with loose soil, forming a comb. In this case, unlike the prototype (3), when using a hiller, additional time is not required to adjust the distance between the disks (1). In this case, the angles α and β provide an optimal crest of an earthing up and do not require adjustment.

Due to the simplicity and rigidity of the design, the hiller has a long service life without the need for maintenance.

Industrial applicability.

The claimed technical solution is implemented using industrially produced devices and materials and can be applied at any agricultural enterprise and in personal subsidiary plots.
