Abstract

FIELD: agriculture.

SUBSTANCE: tool comprises a handle, a working plate and a depth limiter. The handle is fixed to the depth limiter in the central part by means of screws via holes arranged on a fixator and a stop that are rigidly fixed to the depth limiter, or via holes in the depth limiter and clamp. On side parts of the depth limiter at both sides there are plates arranged with slots and plates with holes or plates with slots and holes, through which the working plate is fixed to the depth limiter. The working plate consists of two sides and a knife with the possibility of installation of an additional knife.

EFFECT: tool makes it possible to process soil with specified depth with account of a human being's height.

Description

The invention relates to agriculture, in particular to devices for tillage and cutting weeds.

Known manual tool [RU 2315454 C1, A01B 1/00, A01B 1/02, 01/27/2008] containing interchangeable canvases of a shovel or pitchfork with stops for legs and a wooden handle mounted on an arm. The proposed device allows you to use it in the form of a shovel, pitchfork and grass cutter. However, this device is not equipped with a depth gauge for tillage.

Known manual tillage implement (plane cutter) [RU 2201047 C2, 7A01B 1/08, 03/27/2003], which is equipped with a device for adjusting the inclination of its blade relative to the axis of the handle depending on the height of the worker. However, this tool does not have the ability to control the depth of tillage.

Known garden tools [US 134062 A, cl. A01B 1/08, 05/18/1920], having a working body in the form of an elongated cone with a bent end, to which the handle is attached. However, the functionality of this tool is limited by pulling weeds when working with an elongated cone in the horizontal plane and deep loosening of the soil when working in a vertical plane. This device does not allow you to adjust the depth of tillage.

The objective of the invention is the creation of a device that allows you to process the soil with a given depth of treatment, taking into account human growth.

To solve this problem, a cutting tool is proposed, which consists of a depth gauge 1, to which a stalk 2 is attached in the central part by means of screws 3, or in another known manner through holes 4 located on the lock 5 and the stop 6 rigidly attached to the depth gauge 1. On the side parts of the depth gauge 1 on both sides are plates with slots 7 and plates with holes 8. To the depth gauge 1 through slots of plates with slots 7 and holes of plates with holes 8 with the possibility of removal and regulation Rovkov installed through the holes 9 formed in the sidewalls 10, the operating plate 11 consisting of two side walls 10 and the blade 12 with the possibility of setting the additional blade 13. Mounting of the operating plate 11 to the depth stop 1 formed in any known manner, for example by means of a bolted connection 14.

In addition, by making a hole in the depth gauge 1 (FIG. 2), it is possible to exclude the stop 6 from the design of the cutting tool and fix the handle 2 through the hole in the depth gauge 1 by means of screws 3 or in another known manner through holes 4 located on a rigidly attached to the limiter depth 1 of the latch 5. Also, to facilitate the manufacture of the cutting device, it is possible to replace the plates with slots 7 and the plates with holes 8 (Fig. 3) by plates in which the slots and holes are made (Fig. 4).

The device is brought into operation as follows.

Depending on the required processing width, a working plate 11 is selected (FIGS. 1, 2) and, if necessary, an additional knife 13 is attached to it by any known method.

The depth of processing is adjusted by fixing in any way (for example, by bolting) through the combined holes of the plate with holes 8 with holes 9 made in the sidewalls 10 of the working plate 11.

The angle of inclination of the handle relative to the knife 12 is carried out by turning the working plate 11 in the holes of the plate with holes 8 to align the holes 9 with the slots of the plate with slots 7. Then tightly fix the depth gauge 1 relative to the working plate 11.

When dragging a tillage implement in the soil, the knife 12 deepens to the set depth, depending on the distance between the knife 12 and the depth gauge 1.

The proposed cutting device can reduce the time and cost of physical labor for various types of tillage, including with the possibility of aggregation.
