RU68223U1 - MANUAL SOIL PROCESSING TOOLS - Google Patents

Abstract

The utility model relates to agricultural machinery. The tool contains a holder 1 with a fixed working body having working edges 2. The working body is made in the form of an arcuate curved plate 3 with a notch 4, the sides of which form an apex and are working edges. The angle between the working edges 2 at the apex is from 60 degrees to 120 degrees. Effect: enhanced functionality.

Description

The technical field to which the utility model relates.

The utility model relates to agricultural machinery, in particular to means for mechanical effects on soil and plants.

State of the art

Known pololnik-furrow cleaner containing a semicircular staples mounted on a handle (RU 17108U1, A 61 B 1/06, 03/20/2001). This tillage implement has limited functionality, since it cannot be used as a cultivator and for the formation of furrows.

As the closest analogue, a soil cultivating tool was selected that contains a holder with a fixed working body having working edges (RU 2048711 C1, A 61 B 1/22, 11/27/1995). This product can be used effectively to remove weeds. However, the implementation of the working body in the form of a flat plate with a wide cutting edge makes it difficult to use it as a cultivator and educator

furrows, since considerable effort is required to move the implement in the soil.

Utility Model Essence

The objective of this utility model is to create a manual tillage implement with improved characteristics.

In the course of solving this problem, a set of technical results is achieved, consisting in providing equally effective opportunities for both loosening the soil and cutting weed roots, and the formation and formation of furrows for planting, which extends the functionality of the implement.

The specified set of technical results is achieved by the fact that the manual tillage implement contains a holder with a fixed working body having working edges, the working body is made in the form of an arcuate curved plate with a cutout, the sides of which form the apex and are working edges, while the angle between the working edges at the top is a value from 60 degrees to 120 degrees.

A distinctive feature is the implementation of the working body in the form of a cut-out plate pointed at an optimum angle.

The plate is predominantly triangular and the cutout has a triangle shape similar to the shape of the plate, and the ratio of the area of the plate to the area of the cutout is from 0.3 to 0.8.

The holder is designed to attach the handle and is equipped with at least one means of fixation.

Working edges are sharpened at an angle from 10 degrees to 20 degrees.

The tool is made of sheet steel with a thickness of 1.5 mm to 2.5 mm.

The plate is bent along an arc of a circle with a diameter of 80 mm to 140 mm.

Information revealing the utility model in its entirety. sufficient to implement

A manual tillage implement contains a holder 1 with a fixed working body having working edges 2. The working body is made in the form of an arcuate curved plate 3 with a notch 4. The sides of the plate form a peak and are working edges 2. The angle between the working edges 2 at the top is from 60 degrees to 120 degrees.

The plate is most expediently made triangular, while the cutout 4 is also expediently made in the form of a triangle, similar to the shape of the plate so that symmetrical sides are formed with a height h from 15 to 50 mm. It was experimentally established that the optimal ratio of the area of the plate to the area of the cutout is from 0.3 to 0.8. If the ratio

less than 0.3, then the load on the working person increases, depending on the area of interaction of the working body with the soil. If the ratio is more than 0.8, then the working body will not have the necessary rigidity and strength.

The holder 1 is designed to attach the handle 5 and is equipped with at least one means of fixation. As a means of fixation, a ring 6 can be used, pressing the contact points of the holder 1 to the handle 5.

It has been experimentally established that the angle of sharpening of the working edges 2 is optimal from 10 degrees to 20 degrees. At an angle of less than 10 degrees, blunting and wear of the working edges occur, especially near the apex. At an angle of more than 20 degrees, cutting thick roots of weeds is difficult.

It is most technologically advanced to make a holder and a working body from sheet steel with a thickness of 1.5 mm to 2.5 mm, and bend the working tool plate 3 along a circular arc with a diameter of 80 mm to 140 mm. The bending parameters of the plate are determined based on the required width of the furrows.

The device operates as follows.

The worker, holding the tool with his hands on the holder or the handle, carries out mechanical action on the soil on the principle of a hoe.

Loosening of the soil is ensured by impact with a small amplitude. By increasing the scope and thereby increasing the effect on the soil, it is possible to cut the roots of plants, thereby weeding.

Using this tool, furrow formation can be carried out by reciprocating movements of the working body along one path, without interrupting contact with the soil.

Thus, the implementation of the working body, pointed at an optimal angle allows you to expand the functionality of the tillage.
