Description

The proposed utility model relates to agriculture, concerns a manual tillage implement that can be used for loosening, leveling the soil, removing weeds, making furrows for sowing seeds, and hilling plants.

Known manual tillage tool containing the working body, the handle and the holder mounted on the handle, while the working body is mounted on the holder and made in the form of a rectangle, or a square, or an equilateral trapezoid (RU 93001975 A. class. Α01Β 1/08. A01B 1/20 publ. 08/27/1995) The well-known tillage implement is a set of three hoes with different shapes of the working body and is intended mainly for working with a horizontal blade from top to bottom with pulling on itself, which significantly narrows the range of processing operations ground.

Known manual tillage tool containing fasteners (mounting ring), a handle, a working blade with a blade, a hole and longitudinal knives, while the lateral parts of the working blade are bent, the blade is perpendicular to the longitudinal axis of the blade, longitudinal knives are placed symmetrically relative to the longitudinal axis of the working blade between the hole and the blade and bent through one on opposite sides at an angle to the canvas, and the mounting ring is placed on the canvas coaxially with the hole (RU 2060609 C1, class A01B 1/06, publ. 05.27.1996). The known device allows you to perform work only with a horizontal blade from top to bottom with pulling on yourself, while the working canvas is deepened by a significant amount and captures a large amount of soil, which is a laborious and inefficient process. In addition, the location of the working blade under a straight flange to the mounting ring does not allow flat-cutting soil treatment, which reduces the range of tillage operations and limits the functionality of the device.

A manual tillage tool is known which comprises a working blade made in the form of a flat plate with a blade located along its perimeter, an opening and knives located symmetrically by its longitudinal axis to the working blade. fasteners located on the axis of the working blade from different sides of the hole and made in the form of two plates bent to opposite sides, as well as a handle, the implement is equipped with a removable holder containing a head located at an angle to it, made in the form of a semicircle a hexagonal cutout and a rectangular cutout with grooves, fasteners are provided with stops and installed to interact with opposite sides of the hexagonal and rectangular cutouts of the heads and the holder, the head of the removable holder is equipped with a blade located around the perimeter of the semicircle (RU 2255449, class AB01 1/00. Λ01Β 1/06. publ. 10.07.2005). The gun improves productivity, provides enhanced functionality. The disadvantage is the complexity of manufacture and use, requiring readjustment of the gun.

Known tillage tool containing a holder with a fixed working body having working edges (RU 2048711 C1, CL A61B 1/22. Publ. 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 a furrower, since considerable effort is required to move the implement in the soil.

Known manual tillage tool that 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 a peak and are working edges, the angle between the working edges at the top is from 60 degrees to 120 degrees. Effect: enhanced functionality.

Known V-shaped hoe containing a hollow holder, at the end of which perpendicular to its axis is fixed to the working body. V-shaped curved along the axis of symmetry (http://dewitrussia.ru/en/garden_tools/hoes/).

The closest in technical essence and the achieved result to the proposed utility model is a chopper with teeth, information about which is published on the Internet at http://mastersamodelka.ru/blog/tjapka_s_quot_zubjami_quot/2011-01-21-259, taken as the closest analogue (prototype).

The chopper with teeth contains a hollow holder, on the end of which a working body is fixed perpendicular to its axis, made in the form of a flat plate. The upper part of the working body is made trapezoidal, and the lower part - with a rounded cutting edge, on which small frequent teeth are cut.

An advantage and a common feature with the proposed utility model is that the lower part of the working body is rounded with teeth, which simplifies the hilling of plants on dry, crusty soil. In addition, the implementation of the lower part of the rounded shape allows you to get a rounded groove, in which due to uniform absorption into the soil eliminates the accumulation, stagnation of water during irrigation, which prevents erosion of the soil.

However, the prototype is not without drawbacks:

- firstly, the implementation of the working body in the form of a flat plate makes it difficult to use it as a cultivator, since it takes considerable effort to move the implement in the soil, which significantly reduces the range of tillage operations;

- secondly, when working on wet soil, the design of the teeth does not prevent soil from sticking to the working body, which reduces the quality of tillage and labor productivity:

- thirdly, the fastening of the working body at a right angle to the holder also reduces the functionality of the tool and reduces labor productivity.

The objective of the utility model is the improvement of a manual tillage implement.

The technical result of using the utility model is the expansion of functionality, improving the quality of tillage, increasing labor productivity.

This is achieved by that. that in a manual tillage implement, including a hollow holder, on the end of which a working body is fixed, the lower part of which is rounded with teeth, the working body is V-shaped bent along the axis of symmetry, and spaces are made between the teeth; the holder is connected to the working body at an acute angle; the upper part of the working body is made trapezoidal: the bending angle of the working body is 100 ° -120 °; the teeth are bent inward towards the holder.

Figure 1 presents a drawing of a General view of a manual tillage implement.

Figure 2 presents a drawing of a manual tillage implement in the case of connecting the holder with the working body through the plate.

Figure 3 presents a drawing of a manual tillage implement in the case of the implementation of the upper part of the working body of a trapezoidal shape.

Figure 4 presents a drawing of a General view of a manual tillage implement with bent teeth.

Structurally, a manual tillage implement in figures 1-4 contains:

1 - holder;

2 - working body:

3 - teeth;

4 - plate;

5 - fasteners.

The holder 1 is hollow.

At the end of the holder 1 is fixed the working body 2. the upper part of which is made in a rectangular shape, and the lower part is made rounded with teeth 3.

The working body 2 is V-shaped bent along the axis of symmetry.

Between the teeth 3 there are gaps.

The holder 1 can be connected to the working body 2 at an acute angle.

The upper part of the working body 2 can be made trapezoidal.

The bending angle of the working body 2 can be 100 ° -120 °.

The teeth 3 can be made bent inward towards the holder 1.

Assembling a utility model is as follows.

The holder 1 is made of a pipe, for example, with a diameter of 20-40 mm. a length of 50-100 mm By stamping from metal, mainly from sheet steel, make a working body 2. for example, a height of 70-210 mm and a width of 80-260 mm. with a rounded bottom, a radius of 12-40 mm. with teeth 3. 10-30 mm high. One tooth 3 is performed on the axis of the working body, and the rest with gaps to the right and left of it, at the same distance from each other. For example, a working body with 5-11 teeth can be manufactured. The teeth 3 can be bent inward, towards the holder 1. Bend the working body 2 along the axis of symmetry, for example, 100 ° -120 °. Connect the holder 1 with the working body 2, for example, by welding, welding the holder 1 to the working body 2 at an angle equal to 70 °. The holder 1 with the working body 2 can also be connected in another way. To do this, I weld to holder 1! a plate 4. in the upper part of the working body 2, a hole is made on its axis, a holder 1 with a welded plate 4 is inserted into the hole of the working body 2 and, using fasteners 5. for example, by means of rivets, the working body 2 is connected to the plate 4. The teeth are pumped 3. In the holder 1 set the handle.

The proposed utility model works as follows.

Holding the handle, make the movement of the working body 2 from top to bottom with pulling on itself. In this case, the lower rounded part of the working body 2 with teeth 3 delaminates a part of the soil, and the upper rectangular part of the working organ 2 further further delaminates the separated soil layer, at the same time contributing to the retention of soil captured by the implement. By reciprocating movements of the working body 2 along one trajectory, without interrupting contact with the soil, grooves for sowing seeds, as well as grooves for draining melt water in the spring, and hilling of the partitions are performed. Loosening of the soil is provided by impact with a small amplitude of the working body 2, so that the lateral teeth 3 simultaneously touch the soil. In this case, the teeth 3 destroy the soil crust, the soil, falling into the spaces between the teeth 3, is saturated with air. Increasing the scope and thereby enhancing the effect on the soil, weeding is carried out. In this case, the teeth 3 cut into the soil, cut the roots of weeds, cling and pull them along. Leveling the soil is carried out by the upper part of the working body 2. previously inverted, by reciprocating movements to and from yourself.

The implementation of the working body 2 V-shaped curved along the axis of symmetry allows you to work with a manual tillage tool in row spacing, in small areas, which extends the functional capabilities of a manual tillage implement.

In addition, the implementation of the working body 2 V-shaped curved along the axis of symmetry and the implementation of the gaps between the teeth 3 provides a decrease in the area of the contacting surface of the implement with the soil, reducing soil resistance to the implement, which requires less effort, which helps to increase labor productivity.

The presence of gaps between the teeth 3 also contributes to improving the quality of cultivation and the quality of the soil

The implementation of the teeth 3 bent inward towards the holder 1 increases the efficiency of loosening and removing weeds.

The connection of the holder 1 with the working body 2 at an acute angle allows you to pick up the soil and break it apart on the sides with less effort, providing increased productivity.
