Abstract

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture and can be used in home gardens and farms. Soil digging and tillage device comprises two handles 2 and 3, blade 4 and soil tillage elements 9. Device comprises frame 6, consisting of two semi-frames 11 and 12, articulated to each other by transverse shaft 5 with possibility of semi-frames angular turn in vertical plane. At that, at transverse shaft one end bushing 16 is rigidly fixed, rigidly connected to first handle 2, at transverse shaft opposite end mounting bushing 15 is rigidly fixed. On transverse shaft coaxially with possibility of axial rotation hollow cylinder 7 is installed with blade 4 and second handle 3 rigidly fixed on it. At that, front semi-frame has lengthwise side links 14, one ends of which are rigidly fixed on front transverse tubular element 13, and other ends are rigidly fixed on bushing 16 and mounting bushing 15. Rear semi-frame 12 has skids 1, which on rear side are rigidly connected with harrow 9, and on other side are connected by crossbars, which during device operation interact with blade for cut soil layer tillage.

EFFECT: due to fact that device does not rise above ground level, but moves along soil surface, technical result consisting in working process alleviation is achieved.

Description

The invention relates to agriculture and can be used on personal plots and in farms.

Known shovel (see RF patent for utility model No. 56763, 2006, M.cl. A01B 1/02) containing a blade, a main handle associated with the blade, and an additional handle mounted motionless at an angle to the main handle in the plane perpendicular to the plane of the blade.

This device does not have movable elements, and therefore working with a shovel is difficult, since it requires sufficient human force when lifting and turning the soil layer and cutting it.

A shovel is also known (see RF patent for utility model No. 74264, 2008, M.cl. A01B 1/02), containing two handles kinematically connected to each other, one of which is attached to a blade made in the form of a pitchfork, and the other with knives for cutting the soil.

The disadvantage of the shovel is that each time it is necessary to pull out the shovel with the soil and move it to a new position, applying additional force.

The objective of the invention is to facilitate the workflow.

The solution to this problem is achieved by the fact that in the device for digging and loosening the soil, containing two handles, a blade and elements of loosening the soil, it contains a skeleton consisting of two half-frames, interconnected by a pivotally transverse shaft with the possibility of angular rotation of the half-frames in a vertical plane, with this sleeve is rigidly fixed to one end of the transverse shaft rigidly connected to the first handle, and the installation sleeve is rigidly fixed to the other end of the transverse shaft, while axially axially axially mounted on the transverse shaft a hollow cylinder with a blade and a second handle rigidly fixed on it is installed for rotation, the front half frame having longitudinal lateral connections, one ends of which are rigidly fixed to the front transverse tubular element, and the other ends are rigidly fixed to the sleeve and the mounting sleeve, while the rear half frame has runners, which are rigidly connected to the harrow on the back side, and on the other hand are connected by cross members, which during operation of the device interact with the blade to loosen the cut soil layer.

In FIG. 1 shows a device for digging and loosening soil, general view; in FIG. 2 - device when moving from a transport position to a working position; in FIG. 3 - the device in the working position, in FIG. 4 - the device in the mode of movement of the unlocked transverse tubular element by the step size.

A device for digging and loosening the soil contains two handles 2, 3, a blade 4 and elements of loosening the soil 9, 8. The device contains a skeleton 6, consisting of two half-frames 11 and 12, interconnected pivotally 10 by a transverse shaft 5 with the possibility of angular rotation of the half-frames 11 , 12 in the vertical plane. At the same time, a sleeve 16 is rigidly fixed to one end of the transverse shaft 5, rigidly connected to the first handle 2, and to prevent horizontal movement of the transverse shaft 5, an installation sleeve 15 is rigidly fixed to the other end of the transverse shaft 5. a hollow cylinder 7 with a blade 4 and a second handle 3 fixed thereon. Moreover, the front half frame 11 has longitudinal lateral connections 14, one ends of which are rigidly fixed to the front transverse tubular element 13, and others the ends are rigidly fixed on the sleeve 16 and the installation sleeve 15. The rear frame 12 has runners 1, which are rigidly connected to the harrow on the rear side and connected by cross members 8, which, when the device is in operation, interact with the blade 4 to loosen the cut soil layer.

The device operates as follows.

When transferring the device from the transport position to the working position (Fig. 2), the frame 11 rotates 180 degrees relative to the frame 12 until the frames 11, 12 come into contact with the soil. Then the handles 2 and 3 are rigidly mounted on their seats. In this case, the blade 4 is located horizontally.

Before starting work, a person presses a foot on the transverse tubular element 13 and blocks it. Further, the half frames 11 and 12 are placed by the handles 2 and 3 at the required angle with respect to each other, sufficient for the handle 3 to install the blade 4 at a certain angle with respect to the soil (Fig. 3). The harrow 9 of the half frame 12 moves a step.

Pressing the foot on the hollow cylinder 7, the blades 4 are deepened (Fig. 4). In this case, the unlocked transverse tubular element 13 of the half frame 11 is moved by the step size, and the half frames 11 and 12 are again placed in a horizontal position.

Then the handle 3 is rotated "on itself", and the blade 4, when approaching the cross members 8, break the cut layer into pieces. When this harrow 9 harrows the soil.

Next, the digging process is repeated (Fig. 5). Thus, the device is promoted.

The effectiveness of the invention is to facilitate the working process due to the fact that the device does not rise above the soil, but moves along the surface of the soil.
