Abstract

The utility model relates to the field of agriculture, specifically to land cultivation in backyards and in flower and vegetable gardens, and particularly to hand-held tools for making pits, holes and openings in the ground for planting bushes and trees and for other similar tasks. The proposed utility model is aimed at decreasing the physical exertion and fatigue of a person making pits, holes or openings in the ground. The technical result is achieved in that a hand-held gardening hole-digger, containing a working body which consists of curved, pointed prongs and which is rigidly affixed to the end of a vertical stand having a handle, is provided with at least two blade elements which are positioned on opposing prongs in the lower half of the inner space of the working body, wherein the blade elements are connected to one another in the horizontal plane by means of the upper portions thereof with the ability to form a flat area under the soil, and the lower portions of said blade elements are connected to the prongs along the bend line of the prongs, and the cutting edge of each blade element is positioned so as to be able to partially cut the walls of the openings in the ground beyond the working area of the prongs.

Description

Manual Garden Drill

The utility model relates to the field of agriculture, in particular, to farming in household plots, gardens and vegetable gardens, namely, hand tools for making holes, holes and holes in the ground for planting bushes, trees, and other similar works.

It is well known that pits, holes and holes in the ground for planting bushes and trees in household plots are usually performed manually with bayonet shovels.

The inconvenience in the use of such shovels is the need to bend over during work, which leads to quick fatigue of a working person.

Known manual cultivator (utility model RU N212031 1, class A01B1 / 00, 09/20/2012) containing a vertical stand with a rotary handle and a working body, which is a curved pointed teeth oriented in the direction of movement of loosening the soil and connected in the upper parts with the possibility of installing a vertical rack on them.

However, the well-known utility model for treating soil is used for cutting and pulling weeds.

The closest in technical essence to the proposed utility model is a manual drill for forming holes in the soil (patent RU JN22262579, class E 21B10 / 44, 10.20.2005), containing a rod having a tip in its lower part, equipped with a handle and a cutting unit located in the lower part of the rod, formed by two working bodies fixed one below the other on the rod, each of which is made in the form of a screw. The proposed utility model was created on the basis of the development of a manual cultivator (utility model RU, JY212031 1, CL. А01В 1/00, 09/20/2012) by constructive modification of the hand tool and is aimed at reducing physical exertion and fatigue of the worker during execution holes, holes or holes in the ground.

The technical result is achieved by the fact that a manual garden drill containing a working body of curved pointed teeth fixed at the end of a vertical stand with a handle is equipped with at least two knife elements located in the lower half of the inner space of the working body on opposing teeth, moreover, the knife elements with the upper parts are interconnected in the horizontal plane with the possibility of forming a ground under the ground, and the lower parts are connected with the teeth along the bending line of the teeth, p and the cutting edge of the knife elements disposed to partially sublattice zaniya walls of holes in the soil outside the working zone of the teeth.

The utility model is illustrated by drawings.

In FIG. 1 shows a manual garden drill in a perspective view, a general view; in FIG. 2 - front view;

Fig. 3 is a side view;

figure 4 is a top view.

A manual garden drill contains a working body 3 rigidly fixed at the end of a vertical stand 1 with a handle 2.

The working body 3 is a curved pointed teeth 4 oriented in the direction of movement of loosening the soil. At the top, the teeth 4 are connected with the possibility of installing them on a vertical rack 2.

The working body 3 is equipped with two knife elements 5, 6, made in the form of curved plates with a cutting edge 7 and located in the lower half of the inner space of the working body 3 on opposite teeth 4. The knife elements 5, 6 with the upper parts 8, 9 are connected to each other in a horizontal plane with the possibility of forming a platform 10 under the ground, and the lower parts 11, 12 along the line of the bending of the teeth are connected to the teeth 4 located opposite each other, diagonally.

The cutting edge 7 is located outside the working area of the teeth 4 with the possibility of additional partial cutting of the walls of the holes in the ground, which provides easier extraction of the working body 3.

The vertical rack 1 is made with the possibility of extension to the desired height using threaded clips 13.

Manual garden drill works as follows. The working body 3 is installed on the surface of the soil. Turn the handle 2 clockwise until the teeth 4 penetrate into the ground. With further rotation of the drill, it plunges into the ground until it contacts the cutting edge 7 of the knife elements 5, 6. The cutting edge 7 is embedded in the soil when it is already partially loosened by the teeth 4 and additionally partially cuts the walls of the holes in the soil.

When the drill is immersed, the loosened soil along the curved part of the knife elements 5, 6 enters the horizontal platform 10 formed by the upper parts 8, 9. After the drill is drilled to the desired depth, the rotation is stopped and pulled out of the hole together with the loosened soil. The soil is shaken off the drill and the process of performing holes is repeated.

Thus, the proposed utility model has good operational properties, is convenient to use, allows to increase labor productivity, since a hole is performed in one working stroke, it is easily removed from the ground, all this provides the opportunity to work standing up and reduce fatigue, turning routine work in pleasure.
