RU209192U1 - RIPPER - Google Patents

Abstract

The tool is designed for loosening the soil and cutting the roots of weeds. The ripper contains a working body 1, a handle 2 with a sleeve 3 and a stand 4 for connecting the working body 1 with the handle 2. The ripper is equipped with a ratchet mechanism (ratchet) mounted on the sleeve in the middle of the handle 2.

Description

The utility model relates to farming in household plots, namely, hand gardening tools for loosening the soil and cutting weed roots.

A manual cultivator is known (RU patent for invention No. 2153787, IPC A01B 1/06, published on 08/10/2000), containing a sliding S-shaped handle rigidly connected to a vertical rod connected to the working body.

When loosening the soil, despite the comfortable handle, a working person expends some effort to turn the tool. The need for repeated turns requires significant energy consumption, which leads the worker to fatigue.

The closest technical solution to the claimed utility model is a ripper (RU patent for utility model No. 200455, IPC А01В 1/06, published on October 26, 2020), containing a vertical stand, a T-shaped curved handle and a working body in the form of sharpened plates , interconnected at the top in the form of an irregular polygon.

часть или 180°, что не позволяет одним движением осуществить полный поворот рабочего органа и тем самым произвести качественное рыхление без прикладывания больших физических усилий.The disadvantage of the known ripper is that when an action is performed by the working body, the rotation of the tool is possible only on

part or 180 °, which does not allow one movement to complete the rotation of the working body and thereby produce high-quality loosening without applying great physical effort.

The utility model is aimed at reducing fatigue by improving the tool, which allows you to quickly and efficiently process any personal plot with minimal effort.

The technical result is achieved by the fact that the ripper containing the working body, the handle with the sleeve and the stand connecting the working body with the handle, is equipped with a ratchet mechanism consisting of a barrel, an asterisk and a toggle hook mounted on the sleeve in the middle of the handle, dividing it into equal parts, rigidly connected to the sides of the barrel, while the sprocket is rigidly mounted on the sleeve under the barrel, and the toggle hook is located on one of the parts of the handle with the possibility of interacting with the sprocket to rotate the ripper.

The utility model is illustrated by drawings.

In FIG. 1 shows a general view of the ripper from the front;

in fig. 2 shows a general view of the ripper, side view;

in fig. 3 shows a general view of the ripper, top view;

in fig. 4 - ratchet mechanism mounted on the ripper handle, front view;

in fig. 5 - ratchet mechanism mounted on the ripper handle, top view.

The ripper contains a working body 1, a handle 2 with a sleeve 3 and a stand 4 connecting the working body 1 and the handle 2.

The ripper is equipped with a ratchet 5 (ratchet) consisting of a barrel 6, an asterisk 7 and a toggle hook 8 mounted on the sleeve 3 in the middle of the handle 2, dividing it into two equal parts rigidly connected (welded) to the sides of the barrel 6.

The sprocket is welded to the sleeve 3 under the barrel 6, and the toggle hook 8 is located on one of the parts of the handle 2 with the possibility of interacting with the sprocket 7 to rotate the ripper. The toggle hook 8 is fixed with a thrust washer 9 welded to the handle 2, and the barrel 6 is fixed with a thrust washer 10 welded to the sleeve 3.

The working body 1 contains distributed spiral teeth 11, which form an open circular profile in plan, interconnected in the form of an irregular polygon.

Spiral teeth 11 are made in the form of plates (knives), smoothly turning into pointed ends, having a cutting edge sharpened along the entire length on the inside.

The handle 2 is made T-shaped, its shoulders are directed in opposite directions from each other.

Rack 4 is made of a metal pipe and is connected with the working body 1 at the bottom, and with the handle 2 - at the top. It has 12 holes for adjusting the height of the tool to the height of the person working with it.

The ripper works as follows.

The height-adjusted tool is installed with pointed teeth into the ground. Then, several short clockwise rotations are made in the ground, without moving the hands, until the ripper is completely rotated by 360 °, cutting the ground around the tool axis.

Thus, a ripper equipped with a ratchet mechanism makes it easier to work with the ground without much effort. This tool is simple and easy to use.

Claims (1)
