Description

The utility model relates to agriculture, in particular to hand tools for soil cultivation for soil crust destruction and weed control in row spacings and is intended for active loosening of soil without bed rotation, loosening of row spacings in narrow row plantings and crops and can be widely used when working in greenhouses, on personal plots, in collective gardens and on experimental and breeding plots in the process of growing seedlings, flowers, greenery in small-sized beds and flower beds, alpine slides and greenhouses under captivity Coy.

A large number of different, simple and combined designs of hoes, weeds, cultivators for inter-row processing of plants are known, in the form of staples, forks, spatulas, straight and curved in the form of rake with 3-5 teeth of different widths and lengths (see A. Anfilofiev. Horse and manual agricultural machinery and implements. M. Selkhozgiz, 1949, p. 167-171). With a wide assortment of such implements, due to the change in the technology of growing plants when cultivating new precocious varieties of intensive type, more and more new manual tillage implements are being developed, the demand for which among amateur gardeners, gardeners and breeders is not reduced.

It is known in particular, "Fokin's Hand Tillage Tool", having a one-sided elongated cantilever blade of a curved shape with a concave cutting edge and a changing angle of inclination of the blade relative to the longitudinal axis of the handle within 45-90 ° (see RF Patent No. 2097952, А01В 1/08. Publ. . 10.12.97. Bull. No. 34).

With good reviews on the use of such a tool in the process of growing potatoes and in the processing of wide aisles, its disadvantages include the fact that, due to the rather large size, it is not convenient to work in film greenhouses and on vegetable beds with narrow aisles (less than 30 cm).

Also known is the “propolnik Radost”, containing a knife with side bevels, connected by a flat rib with a sleeve for a handle for the length of 120-150 cm (see Internet: http://polel.tiu.ru/p470774-propolnik-radost.html).

With the simplicity of the design and the possible convenience of working in a limited space of greenhouses and hotbeds, the propolnik presented on the Internet does not have specific, reasonable sizes and dimensions and shows only the appearance of the product.

The objective of the utility model is to expand the assortment of manual field workers - propolniks of justified limited sizes and parameters for scientists and breeders, gardeners, gardeners, gardeners and greenhouse workers, simple in design, but reliable and easy to use, allowing various work to be carried out with minimal manual labor plant care and weed control.

The problem is solved in that the propolnik knife is made in the form of a concave trapezoid fixed to the connecting inclined rack in one piece with the holder of the handle, while the trapezoidal knife has a concave shape with a curvature in the central part of radius R directed towards the holder, and the inclined connecting rack for attaching the trapezoid knife on its back surface it has a height of 3 to 8 cm, and the width of the base of the trapezoidal knife is 6 to 12 cm with a knife thickness of 1.5 to 2.5 mm, and the cutting edge of the trapezoidal knife has piece on the bottom side at an angle of 15-30 ° and hardness after heat treatment of 50-60 ° according to Rockwell, while the holder of the handle has holes for fixing the handle, having a length of 80 to 120 cm, and the radius of curvature of the Central part of the trapezoidal knife R is 4, 0-6.0 cm.

Figure 1 presents a General view of propolnika manual proposed design and size.

Hand weeding includes (Fig. 1) a concave trapezoidal knife 1, an intermediate inclined rack 2, a handle of the handle 3 with holes for fixing the handle, with details 1; 2; 3 propolniks are interconnected by welding.

The main parameters of the proposed design, such as the radius of curvature R, the central part of the knife, the height of the stand, the width of the base, the thickness and angle of sharpening of the trapezoidal knife, the length of the handle, were determined and adjusted practically by experience and based on feedback during production tests of the experimental series of proposed propolniks.

With the help of the proposed propolnik, weeding is carried out productively, both of solitary grass and very clogged areas of land. Using propolnik allows producing high-quality weeding of weeds, increasing labor productivity. In addition, the proposed tool allows weeding without bending, which reduces the fatigue of the worker. The design and operation of the propolnik allows you to remove not only the stem, but also the root system of weeds.

Propolnik can also be used for thinning crops.

Propolnik allows you to perform several operations: weeding, hilling, loosening the soil, breaking lumps and crusts of the earth, collecting grass. If you need to perform other agricultural work, you can turn Propolnik, for example, into a hoe.

Propolnik allows you to perform the following types of work:

- deep loosening of the soil without turnover of the reservoir;

- shallow loosening and cutting of weeds or surface loosening of the crust formed after heavy watering or rain;

- Bouting of landings;

- cutting strawberry mustache to remove or shorten;

- cutting of overgrowth in hard-to-reach places (for example, under bushes, in tight plantings, etc.);

- all types of soil preparation and planting care in sheltered soil;

- digging seedlings;

- deepening holes or furrows for planting garden crops;

- pruning of stem roots in pome fruit plants to stimulate roots on plantations without picking, etc.

- manual propolnik can work in combination (in technology) with a manual vegetable seeder (patent for utility model No. 97240), which can significantly reduce labor costs when growing agricultural products.
