Description

Technical field

The utility model relates to agricultural implements for manual work and can be used as a tool for pulling, pulling out weed roots in household plots and gardens.

State of the art

An analogue of the claimed utility model is a cultivator-root eliminator (Patent RU No. 143238, IPC АВВ 35/00, published July 20, 2014 Bull. No. 20), containing supporting wheels, a shaft, in the lower part of which teeth are bent in the form of a helical line, and the shaft has a drive and the ability to move in a vertical plane, characterized in that it contains a movable and fixed frame, pivotally connected to each other by an axis, and the support wheels are mounted at the ends of the axis [1].

A disadvantage of the known device is the low productivity with high fatigue of the worker.

The prototype of the claimed utility model is a manual mini-cultivator - root eliminator (Patent RU No. 166099, IPC А01В 1/06, published November 20, 2016 Bull. No. 32), containing a working body of curved spiral teeth, a vertical sliding stand connected by a lower end to the working body and a rotary handle, characterized in that the upper end of the vertical strut is equipped with a T-shaped support element designed to facilitate operation, and under it is placed a rotary handle, perpendicularly connected to the vertical strut [2].

The disadvantage when working with such root eliminators is high fatigue due to the constant load of various muscle groups and low labor productivity.

When preparing the soil or cleaning the site of weeds with a thick and deep root system, such as, for example, dandelion, weed, the most common in garden and orchard plots, well-known root eliminators are not always convenient to use. Removing such weeds from the soil requires some effort to scroll through the cultivator. This creates an inconvenience to the hand in removing weed roots, both on a flat area and in the aisle.

Utility Model Disclosure

The technical result of the claimed utility model is to increase labor productivity while simplifying the removal of weed roots.

The present technical result is achieved in the root eliminator device, consisting of a rotary handle with an axis, and on the axis there is a cylindrical base, on which a working body is fixed in an interference fit along the inner diameter of the spiral.

Such a constructive implementation of the utility model provides:

remove weeds on heavy and soddy soil.

weed removal within crop stands.

weeding without tilting and with minimal physical exertion.

high labor productivity.

Comparison of the proposed solutions with analogues and prototype did not allow to identify in them the features that distinguish the claimed solution, which allows us to conclude that the criterion of "novelty".

Brief Description of the Drawings

The figure shows a General front view of the device, including:

1 - knob-rot;

2 - node folding - unfolding tubular carrier drive;

3 - sleeve;

4 - hairpin;

5 - a wing nut;

6 - washer;

7 - a cylindrical groove;

8 - pin;

9 - the axis of the root eliminator;

10 - a hexagon head bolt;

11 - a cylindrical base;

12 - a working body in the form of a continuous spiral;

13 - a hexagon head bolt;

14 - the last ring of the spiral.

Utility Model Implementation

The rotary knob 1 is bent from the pipe, inserted with a pin 8 pressed into it into the cylindrical hole 7 of the sleeve 3 [3]. Additionally, in the unfolded form, the root eliminator is fixed with a wing nut 5 through the washer 6. On the axis 9, a cylindrical base 11 is mounted and fixed with a bolt 10, on which the spiral-shaped working body 12 is tightened by the tightness of the spiral and fixed by a bolt 13 below the last ring of the spiral 14. Axis the top of the rotary handle 1 is performed in line with the axis 9 of the root, for more accurate deepening of the spiral around the root.

The device operates as follows. A root eliminator is vertically mounted on the aerial part of the root by rotating the rotary knob 1, the spiral-shaped working element 12 is buried in the soil, while the root with the soil is in the spiral cavity and held by the soil, then the root eliminator is removed from the ground along with the soil and the root, holding stems the root and rotating in the opposite direction, the spiral releases the working body for the next operation.

Thus, the use of the proposed root eliminator allows you to perform work with minimal effort and, as a result, increase labor productivity. This useful model is aimed at creating a manual root eliminator with improved performance properties that will facilitate labor and reduce the rapid fatigue of various muscle groups by simplifying the removal of weed roots.
