Description

The utility model relates to agricultural engineering, in particular to machines for digging up seedlings of fruit and berry, forest and ornamental crops.

The known excavation mounted plow VPN-2 [Mechanization of work in horticulture / V.K. Kuteynikov, N.P. Losev, A.V. Chetvertakov and others - 2nd ed., revised. and additional - M.: Kolos, 1983. 319 p. - p. 134], which is intended for digging up one- and two-year-old seedlings of fruit, berry and forest crops. The plow contains a frame on which a U-shaped digging bracket is mounted with loosening plates bent upwards fixed in its rear part, a support wheel, a stability knife and a hitch.

The disadvantage of the known digging plow is the low quality of the technological process of digging up seedlings.

A machine for digging up seedlings is known (see RF patent No. 203564, 04/12/2021 - prototype), containing a frame on which a stability knife, a linkage mechanism, a support wheel, a digging bracket with a plowshare made in a U-shape, rippers and a mechanism are installed to create vibrations on them.

A significant disadvantage of this machine for digging up seedlings is the low quality of the technological process of digging up seedlings. This disadvantage is due to the fact that one triangular-shaped plowshare is installed on the digging bracket, which is not capable of ensuring smooth cutting of the root system of the seedling

The technical result of the proposed utility model is to improve the quality of the technological process.

The technical result is achieved by the fact that in a plow for digging up seedlings, containing a frame on which a stability knife, a linkage mechanism, a support wheel, an undermining bracket with a ploughshare, made in a U-shape, rippers and a mechanism for creating vibrations on them, according to the useful model, on the lower part of the digging bracket along the perimeter of the cutting edge there are three plowshares installed in the form of replaceable arrow-shaped knives.

The novelty of the stated technical result lies in the fact that due to the use of three shares in the form of replaceable arrow-shaped knives, during the operation of digging up seedlings, the root system of the plant will be smoothly cut, eliminating breakage and damage to the root, which will lead to an increase in the quality of the technological process.

The proposed utility model is industrially applicable and can be used for digging up seedlings of fruit and berry, forest and ornamental crops.

The essence of the proposed technical solution is illustrated by the drawing, where

in fig. 1 - plow for digging up seedlings, front view;

in fig. 2 - the same, top view;

in fig. 3 - the same side view.

A plow for digging up seedlings contains a frame 1 on which a stability knife 2, a linkage mechanism 3, a support wheel 4 and a digging bracket 5 are installed. In the lower part of the digging bracket 5 along the perimeter of the cutting edge there are three plowshares 6 installed in the form of replaceable arrow-shaped knives. At the rear of the digging bracket 5, rippers 7 are attached. The rippers 7 are connected to a mechanism for creating vibrations 8, which is mounted on the frame 1.

Replaceable arrow-shaped knives 6 are installed on the front side of the digging bracket 5 using a fastening connection. This connection will allow you to replace arrow-shaped knives that have worn out during operation.

A plow for digging up seedlings works as follows.

Before starting work, the digging bracket for seedlings is aggregated using a linkage mechanism 3 with a power source. During the working stroke, the mechanism 8 is activated to create vibrations on the rippers 7, and the digging bracket 5 with the ploughshare 6 is buried in the soil. The plowshares 6, which are made in the form of replaceable arrow-shaped knives, first smoothly cut a narrow layer of soil with a root system and direct it to the digging bracket 5. The digging bracket 5 cuts off the soil layer in the horizontal and vertical plane and moves it along its working surface. Then the soil layer with the seedling is moved to the rippers 7, which, due to the mechanism for creating vibrations 8, make intense vibrations. As a result of vibrations of the rippers 7, the soil layer is destroyed, and the connection between the root system and the soil is disrupted.
