Abstract

The invention relates to agriculture, and more particularly to a gardening hand tool, and can be used for working the soil and for other types of agricultural and general building tasks. A self-cleaning shovel comprises a cleaning device. The cleaning device consists of a plate having a hole that passes through a metal blade, and a movable handle for moving said plate, the handle being disposed above a compression spring surrounding a tubular sleeve. The technical result is an improvement in the working characteristics of the shovel, a reduction in the time and physical effort required to clean the blade and, consequently, an increase in the productivity of the user.

Description

SELF-CLEANING SHOVEL

FIELD OF TECHNOLOGY

The invention relates to agriculture, in particular, to manual gardening tools, and can be used for tillage, other types of agricultural and general construction work.

PRIOR ART The closest to the claimed device is a summer cottage shovel [TU 14-579-04-89, GOST 19596], made of a flat-bent metal blade along the axis from the side of the front part, the lower part of which has a sharpened cutting edge, and in the upper part a tubular clamp is made along the axis of the canvas for attaching a wooden handle in it. To the left and to the right of the tubular clamp, on the canvas, in the direction of the front of the canvas, lapels are made for setting the legs.

The disadvantage of the device is that in the case of adhesion of soil, cleaning the metal sheet requires certain skills and significant efforts on the part of the user. The cleaning operation reduces the performance of using and operating the device, and may lead to its breakdown.

DISCLOSURE OF THE INVENTION The technical problem to be solved by the claimed device is to reduce the time and physical effort of the user when cleaning the metal blade of the shovel and, thus, to increase labor productivity, as well as to reduce the likelihood of breakage of the device during cleaning ...

The technical problem is achieved by the fact that the proposed device contains a handle and a metal blade fixed at one end, the lower part of which has a sharpened cutting edge. In the upper part of the web along the axis, a tubular clamp is made for attaching the handle to it. To the left and to the right of the tubular clamp, on the canvas, away from the front of the canvas, lapels are made for setting the legs. The device contains a cleaning plate, which is formed with an opening, the profile of which corresponds to the cross-section of the metal sheet. The cleaning plate passes through the metal blade and is fixed on a movable handle having lateral longitudinal grooves that allow the movable handle to move the cleaning plate along the metal blade from the leg positioning flaps to the cutting edge and back. A compression spring, located under the movable handle around the stem clamp, allows the cleaning plate to move along the metal blade from the cuffs for setting the leg to the cutting edge and back, return the plate to its original position.

CARRYING OUT THE INVENTION

In principle, the design of a self-cleaning shovel consists of a handle 1 and a metal blade 3 fixed at one end with a sharpened cutting edge, a tubular clamp 7 and cuffs for placing a leg 2, as well as a cleaning plate 4, which is fixed on a movable handle 5, and a compression spring 6, located between the movable handle around the tubular clamp of the shovel. The movable handle 5 has lateral longitudinal grooves 8.

The movable handle 5 provides the movement of the cleaning plate 4 relative to the tubular clamp 7 and the handle 1, and, consequently, the compression and expansion of the compression springs 6, with two degrees of freedom. The overall dimensions of the proposed device are taken in accordance with existing standards for such structures.

The principle of operation of the proposed device: during the operation of the shovel, the cleaning plate 4 is pressed against the tops 2 for setting the leg by means of a movable handle 5 located on top of the released spring 6, surrounding the tubular clamp of the shovel 7. The cleaning of the metal sheet is carried out by the cleaning plate 4, which is moved along the metal sheet 3 from 2 cuffs for setting the leg to the cutting edge and back. To do this, the user pulls the movable handle 5 in side of the metal sheet 3, providing compression of the spring 6. In this case, the metal sheet 3 with flaps 2 passes in the longitudinal grooves 8 and serves as one guide for the movable handle 5, and the handle 1 serves as the second guide. The cleaning plate 4 is returned to its original state by unclamping the spring 6 after the user releases the movable handle 5.

The technical result of the claimed invention is to improve the performance of a self-cleaning shovel, reduce the time and physical effort required to clean the metal sheet, and, consequently, increase the user's productivity.

Claims

CLAIM

Self-cleaning shovel containing a cleaning device, characterized in that the cleaning device consists of a plate containing a hole passing through the metal sheet and driving it with a movable handle located on top of the compression spring surrounding the tubular clamp.
