Abstract

The utility model relates to agricultural engineering, and in particular to means for digging root crops, in particular potato tubers in breeding nurseries. A device for digging root crops contains a frame with a hinged device, support wheels with the ability to control their height relative to the frame, two racks, in the lower part which, in the direction of travel, plant reflectors are located and on the cross between the uprights are two plane-cutting shares, pointed in the middle, trough-like extensions and a fix Ators on racks. To eliminate the inefficient burial of plowshares in the furrow between the ridges at the junction of the plowshares, restrictive skis were installed in the direction of travel. The proposed device for digging root crops helps to reduce energy consumption and increase labor productivity when digging potatoes in breeding nurseries.

Description

The utility model relates to agricultural engineering, and in particular to means for digging root crops, in particular potato tubers in breeding nurseries.

A device for excavating root crops, comprising a frame with a hinged device, support wheels with the possibility of adjusting the height of their location relative to the frame, two racks, in the lower part of which along the cross between the racks there are two plane-cutting shares, pointed in the middle, trough-like extensions and clamps on racks (“Device for excavating root tubers” Patent of the Russian Federation for utility model No. 151728. - 2015. - Bull. - No. 10).

Positive in the device is that the pointed parts of the shares are buried in the middle of the potato ridges.

The disadvantages of this device include:

- the fact that when the device is working, the joint of flat-cutting knives and racks is buried between the potato ridges, where it is undesirable to dig and spend energy on it, and weed vegetation and potato tops are wound on the racks;

- the mechanism for adjusting the depth of motion of the plowshares, the support wheels with the ability to adjust the height of their plowing relative to the frame, do not allow you to set the depth of travel in the furrow at the level of the furrow, which leads to unnecessary energy consumption and reduced productivity of the device associated with inefficient in-depth tillage.

The closest in technical essence, taken as a prototype, is a device for digging root crops, containing a frame with a hinged device, support wheels with the ability to control the height of their location relative to the frame, two racks, in the lower part of which are plant reflectors and on the cross between the racks there are two plane-cutting shares, pointed in the middle, trough-shaped extensions and clamps on the racks (“Device for digging root crops” RF patent for utility model No. 168 356. - 2017. - Bull. - No. 4).

Positive in the device is that the plant reflectors installed in the lower part of the racks in the direction of travel exclude the winding of weeds and potato tops.

The disadvantages of this device include:

- the fact that when the device is running, the joint of the flat-cutting knives and racks is buried between the potato ridges, where it is undesirable to dig and spend energy on this;

- the mechanism for adjusting the depth of motion of the plowshares, the support wheels with the ability to adjust the height of their plowing relative to the frame, do not allow you to set the depth of travel in the furrow at the level of the furrow, which leads to unnecessary energy consumption and reduced productivity of the device associated with inefficient in-depth tillage.

The objective of the utility model is to reduce energy consumption and increase the productivity of the device due to the installation of restrictive skis at the junction of plowshares in the direction of travel and, accordingly, the elimination of inefficient in-depth tillage.

This problem is solved by the fact that in the proposed device for digging root crops, which, like the prototype, contains a frame with a hinged device, support wheels with the ability to control the height of their location relative to the frame, two racks, in the lower part of which there are plant reflectors and on the cross between the uprights two flat-cutting plowshares, pointed in the middle, trough extensions and clamps on the uprights, unlike the prototype at the junction of the plowshares along the way, restrictive skiing.

Thanks to the installation of plowshares at the junction in the direction of the restrictive ski, inefficient plowing of plowshares in the furrow between ridges is eliminated and the productivity of the device is increased.

The proposed device for digging root crops is shown in FIG. 1 and 2, FIG. 1 is a general view of the device, FIG. 2 - section along AA, where: 1 - frame, 2 - attachment, 3 - support wheels, 4 - racks, 5 - cross-member, 6 - plane-cutting shares, 7 - trough extensions, 8 - retainers, 9 - plant reflectors 10 - restrictive skiing.

A device for digging root crops works as follows. In the course of work, plane-cutting shares are buried with pointed parts in the middle into the soil ridge, after the soil with potato nests rises along the plane-cutting shares and extension. On the extension, the soil is destroyed, the nests of potato tubers are exposed, deepened from the soil and remain on the surface of the earth without mixing with the tubers of other potato nests. Thanks to the installation of plowshares at the junction in the direction of the restrictive ski, inefficient plowing of plowshares in the furrow between ridges is eliminated, energy consumption is reduced and the device's productivity is increased.

The proposed device for digging root crops can reduce energy consumption and increase productivity when digging potatoes in breeding nurseries.
