Abstract

The ripper is designed for processing and loosening the soil. It includes a vertical rack 1, a T-shaped curved handle 2, and a device 4 for loosening the soil, containing spiral teeth 5 in the form of plates 7 with a cutting edge 9. 4 fig., 1 ill.

Description

The utility model relates to agricultural implements, namely to hand tools for processing and loosening the soil and can be used for cutting and pulling weeds.

Known manual cultivator (patent RU No. 2153787, IPC А01В 1/06, publ. 08/10/2000), containing a sliding S-shaped handle rigidly connected to a vertical rod with a working body fixed in its lower part in the form of pointed spatially spiral teeth of different radii, which are paired parallel directed spirals of different radii.

The disadvantage of such a cultivator is the creation of high soil resistance when deepening the working body into it by turning the pointed spatially spiral teeth of different radius.

The closest in technical essence is a manual cultivator root remover Tornado (Yandex. Ru, patent RU No. 120311, publ. 20.09.2012), containing a working body with curved pointed teeth oriented in the direction of soil loosening and connected in the upper part to each other in the form of a contour frame with equal sides, on which a vertical stand with a rotary handle is installed.

However, the disadvantage of such a cultivator is the significant energy consumption of a person to overcome the resistance of the soil when deepening and turning the working body of the cultivator.

The claimed utility model is aimed at creating a tool with improved operational properties, which makes it possible to increase convenience in work and labor productivity by reducing human energy consumption.

The technical result is achieved by the fact that in the ripper, which includes a stand having at one end a T-shaped handle with symmetrical shoulders for the left and right hands, and at the other end, a device for loosening the soil containing distributed spiral teeth, forming an open circular profile in plan, which connected in the upper part to each other in the form of an irregular polygon, the spiral teeth are made in the form of plates smoothly turning into pointed ends, having a cutting edge sharpened along the entire length on the inside, while the width of the cutting edge is 2-3 mm, and the thickness of the plate is 4 mm, in addition, the T-shaped handle is bent, its shoulders are bent at an angle relative to the horizontal axis and directed in opposite directions from each other in the direction of movement of the spiral teeth.

The claimed utility model has been created on the basis of numerous tests carried out with analogous cultivators, both in the field during production and with the age group of consumers in their garden plots. Tests have shown that a ripper with such a design of teeth, in the form of sharpened plates, smoothly and easily entering the soil, is very convenient to use. The teeth are made from a plate by laser cutting. The inner part of the teeth is sharpened.

Due to the shape and thickness of the tines, the ripper easily cuts the soil, producing high-quality loosening of the captured volume of soil, especially in viscous, loamy areas. The tool also has a different number of teeth, for example, five. In addition, the design of the handle with a curved shape, the ends of which are directed in opposite directions, makes it possible to overcome turning moments in one convenient movement. The teeth corkscrew when the handle is turned, so it does not require a lot of physical effort to extract the tool.

Thanks to this design, during the operation of the ripper, the entire load is distributed evenly, the person gets less tired, while the productivity increases.

The utility model is illustrated by drawings:

FIG. 1 - General view of the ripper in front;

FIG. 2 - also, side view;

FIG. 3 - also, top view;

FIG. 4 - view A in FIG. 3, sharpening the cutting edge of the plate.

The ripper includes a vertical rack 1, which has at one end a T-shaped handle 2 with symmetrical arms 3 for the left and right hands, and at the other end there is a device 4 for loosening the soil.

The device 4 for loosening the soil contains distributed spiral teeth 5, forming an open circular profile in plan, which are interconnected in the form of an irregular polygon 6.

Spiral teeth 5 are made in the form of plates 7 smoothly turning into pointed ends B, having a cutting edge 9 sharpened along the entire length on the inner side. The plate thickness is 4 mm, and the cutting edge width is 2-3 mm. The T-shaped handle 2 is curved, its shoulders 3 are bent relative to the horizontal axis at an angle α and directed in opposite directions from each other in the direction of movement of the spiral teeth 5.

The ripper works as follows.

The device 4 for loosening the soil is installed on the ground, the handle 2 is turned clockwise and the teeth 5 are screwed into the soil, loosening it and cutting the weeds. The ripper is then lifted up and moved to a new location.

Thus, the use of the utility model in personal subsidiary plots as a tool for soil cultivation will facilitate human labor and develop areas on medium-dense and dense soils.
