Abstract

FIELD: agriculture.

SUBSTANCE: ridger consists of spherical discs mounted symmetrically on vertical racks with the concave sides towards each other. The discs are mounted with the ability of changing the distance between them and adjustment of the angle of attack of the discs. The vertical racks are made of two parts in the form of tubes of a circular cross-section, entering one into another with the ability of rotation for the adjustment of the angle of attack of the discs and with the ability of axial displacement with fixing the parts of the rack in the predetermined positions.

EFFECT: constructive implementation enables to expand the range of adjustment in processing of row spacings at any stage of the plant growth and to reduce energy consumptions.

Description

The invention relates to agricultural machinery, in particular to devices for earthing up during soil cultivation between planting rows of potatoes and root crops.

Known disk working body for tillage (see RF patent No. 2093973, IPC АВВ 23/00, published on 10.27.1997), which contains an axis, half shafts connected with the axis, disks mounted on half shafts with the possibility of changing attack angles and relative position.

The disadvantage of this device is the lack of adjustment of the working body - discs in a vertical plane, which limits the ability to process row spacing when plants reach maximum growth.

Known okuchnik universal (see RF patent No. 2125353, IPC AB 13/02, publ. 01/27/1999), consisting of spherical disks symmetrically located on vertical racks with concave sides to each other with the possibility of changing the distance between them and adjusting the angle disk attacks. The device is taken as a prototype.

The disadvantages of the prototype are limited adjustment possibilities. Adjustment of the working body - discs is carried out by turning the axes in vertical racks. However, when turning the axes in the racks, three adjustment parameters change simultaneously and in mutually exclusive directions. So, increasing the values of some parameters, for example, the angle of attack of the disks and the position of the disks in the vertical plane, at the same time reduce the value of another parameter - the angle of inclination of the disks in the vertical plane, which leads to increased soil shedding into the furrow. This limits the possibilities of adjustment, does not allow to ensure high-quality formation of the ridge and, at the same time, leads to an increase in traction and energy consumption.

The ability to adjust the position of the discs in the vertical plane is limited by the need to ensure acceptable mounting angles of the discs in the vertical and horizontal planes.

The present invention solves the problem of ensuring high-quality formation of the ridge and reduce energy consumption.

The technical result obtained by carrying out the invention is to implement a wide range of adjustment when processing row spacing at any stage of plant growth and reduce energy consumption.

The specified technical result is achieved in that in a disk hiller, consisting of spherical disks symmetrically mounted on vertical racks with concave sides to each other with the possibility of changing the distance between them and controlling the angle of attack of the disks, the new fact is that the vertical racks are made of two parts in in the form of pipes of circular cross section, falling into one another with the possibility of rotation to control the angle of attack of the disks and with the possibility of axial movement with fixing parts of the rack in predetermined positions.

The implementation of the vertical racks of two parts in the form of pipes of circular cross section, falling into one another with the possibility of rotation to control the angle of attack of the disks, allows you to:

- provide a wide range of adjustments to the angle of attack of the disks;

- to form a comb of soil of the desired profile.

For processing light dry soil, the angle of attack is set at 30 degrees. For processing heavy moist soil, the angle of attack is set at 15 degrees.

The possibility of axial movement with fixing parts of the rack in predetermined positions allows you to:

- significantly increase the height of the vertical stands of the hiller, and therefore the distance from the transverse beam of the frame to the soil surface;

- carry out row-spacing processing and hilling without damaging the plants even when they reach maximum growth.

Technical solutions with features distinguishing the claimed solution from the prototype are not known and do not follow explicitly from the prior art. This suggests that the claimed solution is new and has an inventive step.

The invention is illustrated in the drawing, which shows a disk hiller.

The Okuchnik disk consists of a transverse beam 1 of the frame, two spherical disks 2, two vertical posts assembled from the upper 3 and lower 4 pipes. The upper 3 rack pipe is fixed to the transverse beam 1 of the frame in one of several fixation options. A part of the lower 4 pipe is attached in one of several variants of positions in the upper pipe using fasteners 5. Spherical disks are attached to the axles 6 through the bearing assembly 7.

Axis 6 form a certain angle with the bottom 4 of the rack pipe, selected according to the test results, which ensures the inclination of the disk in a vertical plane.

In the middle part of the transverse beam of the frame 1, an arm 8 is made for fastening the hiller to the walk-behind tractor. Mounting is carried out using a coupling device (not shown in FIG.).

Mating parts - the upper 3 and lower 4 pipes of the rack have holes 9 through which fasteners are passed to fix the parts in the selected position. The transverse beam 1 of the frame has a number of holes 10 for installing and fixing the upper tubes of the rack in one of several positions, depending on the width of the row spacings.

The device operates as follows.

The ability to rotate the lower pipe in several positions (at least 2) allows you to provide a wide range of adjustments to the angle of attack of the disks 2 and the formation of the soil ridge of the desired profile. For processing light dry soil, the angle of attack is set at 30 degrees. For processing heavy moist soil, the angle of attack is set at 15 degrees. The possibility of axial movement of the lower 4 pipe rack allows you to significantly increase the height of the vertical pillars of the hiller, and therefore the distance from the transverse beam 1 of the frame to the soil surface. This makes it possible to carry out row-spacing processing and hilling without damaging the plants even when they reach maximum growth. The angle of inclination of the disks 2 in a vertical plane ensures the formation of a ridge and eliminates the shedding of soil back into the furrow. This parameter depends on the geometry of the disk — its diameter and surface curvature. Having once determined the optimal value of this angle, there is no need to change it in the future - it can be incorporated into the design as a constant parameter.

Fixing pipes 3 and 4 of the rack is carried out using fasteners 5, passed through the corresponding holes 9 in the mating parts.

The strict symmetry of the installation of the disks 2 in the working position, which is ensured by the accuracy of the machining of the parts, increases the directional stability of the hiller disk during work, and therefore reduces the effort exerted by the operator on the controls, and facilitates his work.
