Description

Technical field

The utility model relates to hand tools in agriculture and can be used as a multifunctional tool for digging and loosening the soil in the garden, cottage and garden plots.

State of the art

A device for a handle for household equipment is known (Patent RU 58281, IPC А01В 1/02 (2006.01), publication date 11/27/2006 Bull. No. 33), which is a cylindrical body extended along the length, tapering at the end, fixed in the tulle of manual equipment having a marking made on the surface alternating at regular intervals, the marking being a division of the metric ruler with a measuring range from 0 to 100 cm, while zero division coincides with the end surface of the free end of the handle, and the division price is 1 or 2.5 cm or a multiple of 5 or 10 cm.

A disadvantage of the known device is the measuring ability, which allows you to mark a notch, and this does not reduce energy costs during efficient operation.

The closest device is a folding tool for excavation and snow removal (Patent RU 39036, IPC АВВ 1/02 (2000.01), publication date 07/20/2004 Bull. No. 20), containing a working body with a handle rigidly attached to it, consisting of two articulated interconnected parts and a locking device fixing the handle in the working position, and the parts of the handle are interconnected by an axis passing through the eyes rigidly attached to them, the locking device is made in the form of an elastic plate, one end of which is rigidly attached n to one part of the handle, and the other end is made free and contains a protrusion that fits into the working position of the gun in the congruent hole on the other part of the handle.

The disadvantage of this device is the design complexity, the great complexity in operation.

Utility Model Disclosure

The technical result is to reduce energy costs during efficient operation.

The present technical result is achieved in an earthmoving tool containing a working body with a handle rigidly attached to it, consisting of two parts pivotally interconnected and a locking device fixing the handle in the working position, while the parts of the handle are interconnected via an axis passing through the eyes are rigidly attached to them, the locking device is made in the form of an elastic plate, one end of which is rigidly attached to one part of the handle, and the other end is made free and contains a protrusion, walks in the position congruent tool in hole on the other portion of the handle, wherein the operating element is designed as a wedge garden blades with rectangular ledges on both sides of the wedge.

Distinctive features are - the implementation of the working body in the form of a wedge-shaped garden scapula, with rectangular ledges, which gives a reduction in energy costs during efficient operation.

Energy is applied gradually due to the ledges spread on the sides of the shovel. This allows you to reduce the load on the muscles of the hands and back of the worker. Due to the phased rectangular base of the shovel, its penetration into the excavated earth will be easier, since the ledges located on the sides of the bayonet will allow piercing the soil with less effort. A wedge-shaped garden shovel with rectangular ledges allows digging strips of soil to the width and depth of the first ledge or second and so on.

A comparative analysis of the features of the claimed solution with the features of the prototype and analogues indicates the conformity of the claimed solution to the criterion of "novelty."

Brief Description of the Drawing

The figure shows a view of a folding tool for excavation with a working body in the form of a wedge-shaped garden shovel with rectangular ledges, including: a working body 1 in the form of a wedge-shaped garden shovel, having ledges on the canvas on the sides of the bayonet 8, with a handle 2 rigidly attached to it, consisting of of two parts 3, 4 pivotally connected to each other and the locking device 5. Which fixes the working body 1 in the working position. The locking device 5 is made in the form of an elastic plate, one end of which is rigidly attached to the part 3 of the handle 2 and the second end is rigidly attached to the 4 parts of the handle 2. In some cases, the made handle 2 can be attached to the working body 1 by means of a detachable connection, for example, a self-tapping screw 6 The working cloth of the shovel contains stiffening ribs 7.

Folding gun works as follows. For deep digging of the soil, the working body 1 is attached to the handle in the form of a wedge-shaped garden scapula with rectangular ledges, by connecting the handle and the working body with self-tapping screws 6. The ledges located on the sides of the bayonet will allow loosening even the driest soil. In order to dig up the soil, it is necessary to make a minimum of effort, since the shovel is equipped with ledges that allow you to gradually apply energy. Which leads to effective easy digging and loosening. Due to the rectangular base of the shovel, penetration into the excavated earth will be easier, since the ledges will contribute to this.

After the work is completed, the tool is folded by the device 5 and takes on a compact form, and also simplifies the transportation of the tool.

The manufacturing technology of the proposed device is similar to the manufacturing technology of the known device.

Folding tool for earthworks increases productivity and has multifunctional capabilities. The energy costs in this case, compared with the similar process of digging the soil with a conventional shovel, are significantly reduced while improving the quality of the soil treatment.
