Description

The utility model relates to horticultural equipment, namely to a hand drill designed to form holes in the ground for planting bushes, trees and other similar works.

A hand-held garden drill is known (patent for PM No. 133997, IPC A01V 1/00, 10.11.2013) containing a working body rigidly fixed at the end of a vertical rack with a handle made of curved pointed teeth, equipped with two knife elements placed in the inner space of the teeth , the cutting edge of which is located with the possibility of partial cutting of the walls of holes in the ground outside the working zone of the teeth.

The disadvantage of the known auger is that when the auger is deepened, weeds are pierced as well as plant roots and cling to the teeth, thereby requiring more effort to overcome the soil resistance created by these clinging weeds and plant roots.

Closest to the claimed utility model is a well-known hand drill for forming holes in the soil or soil, containing a rod having a tip in its lower part in the form of a drill and a cutting unit welded to the rod above the tip and made of two semi-discs with sharpened straight edges, welded to the bar in such a way that their planes form an angle of 30 ° between themselves (A. Mishin. Homemade products for the garden and vegetable garden. Drill from two half-discs. Crafts and advice. M: Moskovskaya Pravda publishing house, 1990, p. 55, 91. Yandex.ru).

The disadvantage of such a drill is that when drilling, the semi-disks, cutting the ground, experience high soil resistance, requiring great muscle effort, since the cutting disks are immediately included in the process. In addition, performance is not high enough.

The claimed utility model is aimed at creating a high-strength tool, a hand-held garden auger, capable of making it easy to enter hard or stony soil, providing ease of use, productivity and reduced fatigue.

The technical result is achieved by the fact that in a manual garden drill containing a stand with a handle mounted on it in the upper part, and in the lower part - a tip and a working body formed by two semicircular cutting plates with a sharpened edge, and on the cutting plates of the working body metal, located radially spiral teeth, while the plates are fixed at an angle of 40-45 degrees to the horizon on the platforms for their fastening, located above the tip of the rack, the teeth are radially located on the plates and have a taper angle of 20-40 °, the thickness of the cutting edge of the tooth is 1-3 mm, and the thickness of the cutting edge of the plate is 1-2 mm.

The utility model is illustrated by drawings:

in fig. 1 shows the inventive drill, shown in a perspective view, general view;

in fig. 2 is the same as in Fig. 1, front view;

in fig. 3 is the same as in Fig. 1, side view;

in fig. 4 - top view.

The claimed utility model is a manual garden drill, the design features of which make it possible to make holes, holes and pits of different diameters in hard or stony soil, easily, quickly, conveniently and without fatigue.

The drill contains a stand 1, with a handle 2 installed on it in the upper part, and a tip 3 in the lower part and a working body formed by two semicircular cutting plates 4 with a sharpened edge 5.

The cutting plates 4 are provided with metal radially arranged helical teeth 6 fixedly mounted on them and are made removable, with the possibility of replacing them with plates of a different diameter, while the plates 4 are fixed at an angle of 40-45 degrees to the horizon on the platforms 7 for their fastening.

Platforms 7 for attaching plates 4 are rigidly installed in the lower part of the rack 1, above the tip 3 and inclined to the horizon at an angle of 40-45°.

The cutting radial edge 5 of the plates 4 is 1-2 mm.

Metal spiral teeth 6 are made by high-precision forging and are designed for loosening the soil, providing easy entry into hard soil of the cutting edge 5 of the plates 4 following the teeth 6. This is achieved by the fact that the teeth 6 are radially located on the plates 4 and have a sharpening angle of 20-40° , and the thickness of the cutting edge is 1-3 mm.

With such values, during the penetration of the drill into the soil, the roots of weeds and plants do not pierce and do not cling to the teeth 6. This means that no great efforts are required to overcome the resistance of the soil.

The tip 3 is made pointed and is a guide, and the handle 2 is made removable.

The drill works as follows.

The drill is installed on the soil surface with a tip 3 along the axis of drilling the hole. Then turn the handle 2 clockwise until the teeth 6 penetrate into the ground.

Pointed teeth 6 easily loosen the main soil. With further rotation of the drill, the working body is immersed in the ground until the cutting plates 4 come into contact with the ground. The soil loosened by the teeth 6, with further rotation of the drill, goes up the inclined plane of the plates 4. Having immersed the drill to the desired depth, the rotation is stopped and pulled out of the hole along with the loosened soil. The soil is shaken off the drill and the process is repeated.

Thus, the claimed utility model, due to the design features, makes it possible to ensure ease of entry into solid soil, increase labor productivity during manual drilling and reduce fatigue.
