Abstract

FIELD: agriculture.

SUBSTANCE: method is characterised in the fact that the device is twisted in the ground or soil to the desired depth. The device consists of dual hollow tubes. The outer tube has equally spaced protrusions of uniform rectangular section rigidly fixed along the lateral cylindrical surface along the helical line with a constant pitch. After the device reaches the desired depth the inner tube with cohesive soils is removed from the outer tube to form a hollow space. In the hollow space a pole is placed and the outer tube is twisted out. The device is twisted using a handle.

EFFECT: method enables to reduce the physical load in digging holes in cohesive soils and to increase productivity.

Description

The invention relates to the field of technology and agriculture, in particular to equipment and tools, and is intended for digging holes in cohesive soils.

A known tool for the extraction of weeds and / or weeding and a method for extracting weeds and / or weeding [1]. The weed extraction tool contains two teeth fixed on a common handle, immersed in the soil around the weed. One tooth is smooth, and on the other there is at least one hook-shaped protrusion, bent from its free end into the space between the teeth. This hook-shaped protrusion pierces or hooks the weed to the root, and then the implement is simultaneously turned, tilted and pulled out of the soil.

The disadvantages of this technical solution are:

- low efficiency and productivity when digging holes;

- great effort is required in the production of work.

The closest technical solution is a device for digging the earth [2]. The device is equipped with a frame, which is made in the form of two upper and lower parts pivotally connected to each other. The upper part of the frame in the front part has a cross member for moving the shovel handle on it, and the shovel handle has a leg bracket. The lever mechanism is mounted on the frame.

The disadvantages of this technical solution are:

- the relative high cost of the structure;

- great effort is required in the performance of work;

- low labor productivity.

The purpose of the invention is to increase efficiency and reduce physical activity when digging holes in cohesive soils.

This goal is achieved by the fact that a special device is installed on the soil surface (Fig. 1). A special device consists of double hollow pipes, the outer pipe has evenly spaced protrusions of a constant rectangular section rigidly fixed along a cylindrical surface along a helical line with a constant pitch. In the upper part of the pipes there are holes in which the handle is inserted (Fig. 1, 2). Rotational forces are applied to the handle, which results in the rotation of a special device and its deepening into cohesive soil or soil to the required depth. Efforts can be applied by bunks from different sides of the handle. After that, the inner pipe together with the cohesive soil is removed from the outer pipe and a hollow space is formed into which the column is installed and the outer pipe is twisted (Figs. 3, 4). The length of the handle depends on the amount of force required to rotate and deepen the special device.

Figure 1 shows a device for digging holes, General view; figure 2 is a section L-L in figure 1; figure 3 shows a device for digging holes in the context; figure 4 - shows a device for digging holes at the time of extraction of the inner coarse soil in the context.

A device for digging holes is installed on the surface of the earth 1. The device consists of double hollow pipes, the outer pipe 2 and the inner pipe 3. The outer pipe 2 has tabs 4 that are rigidly fixed but on the lateral cylindrical surface but the helix, and at the top of the outer pipe 2 and the inner pipe 3 there are holes 5 into which the handle 6 is inserted. After deepening the device to the required depth, the inner pipe 3 is removed together with the soil 7 and a hollow space 8 is formed into which the column is mounted.

The method of digging holes in cohesive soils as follows. On the surface of the earth 1 is installed a special device (figure 1). A special device consists of dual hollow pipes, the outer pipe 2 and the inner pipe 3 (figure 2). The outer pipe 2 has uniformly spaced protrusions 4 of constant rectangular cross-section rigidly fixed along a cylindrical side surface along a helical line with a constant pitch. In the upper part of the outer pipe 2 and the inner pipe 3 there are holes in which the handle 5 is inserted. Rotational forces are applied to the handle, which rotates the special device and deepens it into the cohesive soil or soil to the required depth (Fig. 3). After that, the inner pipe 3 together with the cohesive soil 7 is removed from the outer pipe 2 and a hollow space 8 is formed, into which the column is installed and the outer rough 2 is unscrewed (Fig. 4). The length of the handle 6 depends on the magnitude of the required force required to rotate and deepen the special device.

The proposed technical solution has a wide range of applications, depending on the hardness of the earth. More effective than analogues and is more economical.
