Description

The utility model relates to manual implements for tillage, mainly for growing potatoes.

Known manual tool for tillage, containing a handle and a hollow holder located in the lower part of the handle, at the end of which is rigidly fixed to the working body in the form of a bracket. A well-known tool is mainly used for digging vegetables and potatoes (Ru No. 2178965 C1, А01D 11/02, publ. 2002.02.10).

However, the known technical solution is effective in a rather limited field of application and requires significant energy costs when digging potatoes, loosening the soil, forming beds, etc., since when working with it, mainly using hand power.

The objective and technical result of the device according to the utility model is to provide the ability to carry out a wide range of work when processing the soil (digging, loosening, digging, etc.) while reducing energy costs when using a hand gun.

The essence of the utility model is a manual tool for tillage with interchangeable working bodies, including a handle, the handle (1) in the upper part additionally equipped with a cross member (2) with handles installed at its ends (3), and in the lower part with a connecting means (4 ) with interchangeable working bodies, which are made in the form of an additional handle (5), with mounted on it

the side of the tillage tool: a blade (6), made in the form of a curved rectangular plate; a knife (7) made in the form of a plate with rounded edges; with a fork (8) made in the form of flat curved teeth, connected on one side.

In addition, the additional handle (5) is provided with a sharp end from below; the handles (3) are mounted vertically relative to the plane of intersection of the handle (1) and the cross member (2); the connection means (4) of the handle (1) with replaceable working bodies is detachable in the form of a threaded connection with a pin fixation, or a spike-groove connection with a pin fixation; the blade (6) is strengthened along the additional handle (5) with a smaller side and is provided with a pointed lower edge (9); the knife (7) is mounted vertically with respect to the plane of intersection of the handle (1) and the cross member (2) and is provided with a pointed lower edge (10); the forks (8) are reinforced with two triangular kerchiefs (11) with the teeth located across the additional handle (5).

The design of the device according to the utility model is illustrated by the drawings in figures 1-4, where:

1 - stalk;

2 - a cross-piece;

3 - handles;

4 - means for connecting the handle to the working body;

5 - additional stalk;

6 - dump in the form of a curved rectangular plate;

7 - a knife in the form of a plate with rounded edges;

8 - pitchfork in the form of flat curved teeth, on the one hand interconnected;

9 - the pointed lower edge of the blade (6);

10 - pointed lower edge of the knife (7);

11 - triangular scarf pitchfork (8).

Tillage tools (blade 6, knife 7, pitchfork 8) of a hand tool according to the utility model (Fig. 1) provide the possibility of digging, forming a bed, burying planted seeds (tubers, bulbs, etc.), hilling and digging. In all cases, the implementation of the implement according to the utility model of its purpose is associated with the movement of soil (its blade) by turning the handle (1) after deepening the tillage tool into the soil. Moreover, the location of these tools relative to the handle (1) and the handles (2), shown in Fig.2-4, is optimal. The implementation of the additional handle (5) in the form of a pointed rod, as well as the implementation of tillage tools with a pointed lower edge, reduces the amount of force required to penetrate these tools into the ground. The presence of the cross member (2) and the arrangement of the handles (3) vertically relative to the plane of intersection of the handle (1) and the cross member (2) make the device more useful and ergonomic according to the utility model. The means of connection in the form of a threaded connection with a pin fixation, or a spike-groove connection with a pin fixation is the most optimal from the point of view of reliability of the connection and eliminates the separation of the elements when the handle (1) is rotated around its axis. However, it is permissible to use any other known means of connecting the ends of extended parts, providing reliable connections and ease of separation if necessary.

Work with a manual tool on a utility model can be illustrated by the following examples.

For digging (forming a bed, digging in), an additional handle (5) is used with a blade (6) mounted on its lateral side (according to FIGS. 1 and 2), made in the form of a curved rectangular plate. The specified handle, equipped with a protruding threaded pin, is connected to the handle (1), provided in the end part with a threaded hole, and fixed with a pin. The blade (6) is installed with a left direction relative to the axis of symmetry of the cross member and the handles (figure 2). Holding the handles, with the left foot they dig the dump (6) into the soil and, turning the crosspiece with the hands to the right, roll off the soil lump to the right. Repeating the specified operation, with the general movement of the digging back, form a bed to the right of the digging.

The location of the blade (6) can be symmetrical, relative to that illustrated in figure 2 (shown by a dotted line). In this case, for digging the blade (6) into the soil, the right leg of the digger will be used, and the turn of the cross-member for the dump of a lump of soil to the side will be left.

The optimal dimensions of the blade (6) is a height of 300 mm, and the required bend is obtained by bending a rectangular plate 400 mm long to a distance between its edges of 300 mm.

To implement loosening or hilling the soil, the handle with the blade (6) is replaced with an additional handle (5) with a knife (7) in a known manner with threaded joints. The knife (7), located vertically and made in the form of a plate with rounded edges (Fig. 3), is pulled deep into

the soil and, rotating the crossbar with your hands left and right, loosen the soil and roll off part of it also left and right. Repeating the specified operation, with the general movement of the digger back, a bed is formed to the right and to the left of the digger (spud).

To dig up, in particular, potato tubers from the beds, an additional shank (5) with forks (8) is installed from the kit. These forks, made in the form of flat curved teeth connected to each other on one side, are installed at some distance from the additional handle (figure 4) using triangular scarves (11) across the handle. Deepening the pointed end of the handle (5) is carried out with the jumper (2) turned to the left by about 90 °. In this case, the teeth of the forks (8) are placed in the down position. After deepening the tip and partially the pitchfork teeth (8), the jumper is turned to the right into the soil. In this case, the teeth of the pitchfork (8) capture the lump of soil of the bed with root crops and dump it to the right.

The indicated actions, as a result of which the soil was processed using a hand-held device according to a utility model, illustrates the achievement of the required technical result: providing the ability to carry out a wide range of work when processing the soil (digging, loosening, digging, etc.) while reducing energy costs when use of replaceable working bodies.
