Essence: the device for loosening the soil consists of a head mounted on an electric drill and made in the form of evenly, rigidly or removablely fixed around the circumference on an annular base of three- or four-sided metal plates in cross section, the working parts of which are located at an angle to the axis.

The utility model is easy to manufacture, provides soil loosening, including in hard-to-reach places.

Description

The utility model relates to agriculture, namely, hand tools for tillage, and can be used for loosening the soil on a personal plot, for mixing various bulk materials, cutting trampled snow and ice from sidewalks and roads.

Conventionally, a portable cultivator with a mechanical, electrical or other drive can be classified as a hand tool.

Patent and information search revealed cultivators driven by muscle power or mechanical, electrical or liquid fuel engine, equipped with a variety of nozzles and designed for different soils. Most are complex both in manufacturing and in use due to the weight of the structure, requiring considerable effort during operation.

So, [1], a combined manual tillage cultivator equipped with a wide handle provides support when the wide forks are immersed in the ground, followed by leaning on the cultivator frame and thus loosening the soil. It is quite obvious that only a very physically strong person can cope with such a load.

A more gentle force will be required when working with cultivators [2] and [3]. And if [2] is simply immersed in the soil and the soil is turned according to the principle of a lever, then the claimed design [3] already has an element of small-scale mechanization - a ratchet mechanism. The claimed cultivator contains a rod with a handle connected to a ratchet mechanism and a device for loosening the soil and cutting roots and removing weeds due to the constant rotation of the handle manually. It requires significant physical effort and a certain free space, which is not always feasible in the conditions of the real placement of garden plantings.

Thus, the result of application of technical solutions [1], [2] and [3] is critical from the point of view of human muscle expenditure.

As a prototype, the applicant of the "manual cultivator" chose the invention [4], which offers a solution in the form of a mobile device with an electric drive for tillage with nozzles. But for a task that requires a simple technical solution, the stated [4] looks redundant and is intended for more professional and qualified maintenance of the land.

Claimed as a utility model "Manual cultivator", according to the applicant, solves the problem of creating a convenient manual cultivator. At the same time, it solves the problem of creating a manual cultivator in an artisanal way and ensures its use without the application of significant human physical effort.

The problem is solved by the fact that an electric drill is installed in the manual cultivator as a drive mechanism, a rod and a head, which is made in the form of an annular base with rigidly fixed or removable plates, each of which is inclined to the rod - from the line of contact with the base - at a certain angle and has cross-sections of a tri- or quadrangle with blades.

The utility model is illustrated in FIG. 1, which shows a general view of a manual cultivator. In a specific version, the manual cultivator contains a drive mechanism 1 (hereinafter referred to as an electric drill). In the clamping mechanism (chuck) of the drill 1, a rod 2 is fixed at one end. At the other end of the rod 2, a head 3 is fixed for loosening the soil, having the form of an annular base 4, on the surface of which metal plates 5 are evenly located around the circumference. Each of the plates 5 is tilted at a certain corner and is rigidly fixed on the surface of the annular base 4 by, for example, electric welding or bolting (not shown in Fig. 1). In cross section, each metal plate 5 can be made in the form of a trihedron (not shown in Fig. 1) or a tetrahedron (not shown in Fig. 1). The angle of inclination of each of the plates 5 is chosen equal to 10 ... 30 degrees as the most rational to ensure high-quality loosening. The angle of inclination is determined by the author experimentally. The metal plate 5, in the case of a tetrahedral section, contains a sharp edge. In the manufacture of a metal plate 5 with a trihedral section, the role of the cutting edge is performed by a protruding edge. Head 3 for loosening the soil can be fixed on the rod 2 rigidly, for example, by electric welding, or removable, for example, by bolting (not shown in Fig. 1).

The work is carried out as follows. The head 3 for loosening the soil is installed in the electric drill 1 and fixed in it by clamping the rod 2 in the chuck of the electric drill 1, which is then connected to the power supply. Depending on the hardness of the soil, the required number of revolutions of rotation of the rod 2 is selected. The author experimentally determined that for high-quality loosening of the soil, it is necessary to provide 30 ... 150 revolutions per minute. The metal plates 5 of the head 3 are brought to the area of soil pre-planned for processing. The electric drill 1 is turned on and the soil is loosened by pressing on the housing. Further, by successive movement of the cultivator, the entire soil area is loosened in compliance with safety measures. Can be used to cut packed snow and ice from sidewalks and roads.

Thus, the use of this manual cultivator facilitates the work of a person, increases labor productivity and provides work in hard-to-reach places due to the mobile, easily transportable design of the utility model.
