Abstract

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture and can be used in household plots and farms. The device for digging and loosening the soil, comprising two handles, a cutting edge and blades for cutting soil, characterised in that the handles are kinematically connected via thrusts with a follower, on which are the cutting edge and blades are rigidly mounted, at that the cutting edge interacts through the slot with a guide hingedly connected with the handles, and performs reciprocating movement when turning the handles at an angle in the plane of the cutting edge.

EFFECT: constructive implementation enables to ease the working process.

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. class 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 another 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 aim of the invention is to facilitate the workflow.

This goal is achieved by the fact that in the device for digging and loosening the soil, containing two handles, a blade and knives for cutting the soil, the handles are kinematically connected by means of rods with a pusher on which the blade and knives are rigidly mounted, and the blade interacts through a slot with a guide connected pivotally with handles, and has a reciprocating movement when the handles are rotated through an angle in the plane of the blade. In the device, the slot can be made in the form of holes or in the form of a slit.

In the device, the knives may be able to adjust the position in height and angle of installation.

Figure 1 shows a device for digging and loosening the soil, a General view; figure 2 - view A in figure 1.

A device for digging and loosening the soil contains two handles 1, a blade 4 and knives 5 for cutting the soil. The handles 1 are kinematically connected by means of rods 10 through pads 11 with a pusher 9, on which a blade 4 and knives 5 are mounted rigidly through the struts 8 and the bar 7. The blade 4 interacts through the slot 14 with the guide 3 pivotally connected to the handles 1 and has a return - translational movement when turning the handles 1 at an angle in the plane of the blade 4. In the device, the slot 14 can be made in the form of holes or in the form of a gap. The blade 4, made in the form of a pitchfork, interacts through holes 14 with the guide 3 and has a reciprocating movement when the handles 1 are rotated through an angle. A possible embodiment of the blade 4 as solid as a conventional shovel, and then a slot should be made on the guide. Knives 5 have the ability to adjust the position in height and angle of installation by attaching them to the bracket 6 of the pusher 9 through threaded connections 13.

The device operates as follows.

Before starting work, the handles 1 are vertical and parallel to each other. The deepening of the blade 4 into the ground is carried out with the foot and the breeding of the handles 12 of the handles 1 to the sides in the plane of the blade 4 due to the kinematic connection of the handles 1, rods 10 and the pusher 9. At the end of the stroke of the pusher 9, the soil layer is cut with knives 5, which can be set to cut the previous or just separated formation. In the process of digging, the device does not provide for its lifting and also does not provide for turning over the soil, but only the device is moved through the soil to a new position. The pulling force of the hands brings the handles to their original position, and the blade 5, moving up, is cleared of adhering soil automatically by the guide 3. With the appropriate installation of threaded joints 13, the position of the knives 5 is adjusted in height and angle of installation.

The effectiveness of the invention consists in facilitating the working process due to the fact that the soil does not rise and is not turned over by the device, and the blade is automatically cleaned of adhering soil when mixing the handles of the device.
