Description

The utility model relates to agriculture on personal plots, namely to manual garden tools for loosening the soil and pruning weed roots.

Known manual garden soil cultivators providing high quality loosening of the soil without overturning the formation and reducing physical activity. (Patent for IZ No. 2654726, IPC А01В 1/00, 05/22/2018, Patent for IZ No. 2598547, IPC А01В 1/00, 07/20/2014)

A disadvantage of such known devices is the inconvenience of use, which consists in the need to tilt when working with them. In addition, a person working with the device has a load of muscles of the same group, which leads to rapid fatigue.

The closest in technical essence is the cultivators combisystem "GARDEHA" (Yandex. Garden cultivators manual 9.48 HD) manual star, containing a handle, frame, knife and working body made in the form of asterisks mounted on the axis of the frame. However, such cultivators loosening the soil do not break the hardened lumps of the earth, when working with such a tool you have to walk on the excavated.

The utility model is aimed at creating a tool that allows you to quickly and efficiently process any personal plot with minimal effort. It is convenient in operation and allows you to facilitate work by reducing the cost of muscle energy when loosening.

The technical result is achieved by the fact that in a hand-held cultivator-ripper containing a frame, a working body mounted on the axis of the frame with the possibility of rotation, a plate with a blade placed on the frame behind the working body for cutting weed roots and loosening the soil and a handle connected to the frame, the working body made in the form of a drum, the sides of which are connected by blades in the form of parallel plates protruding beyond the side surface of the sides, and the blades are installed in such a way that when the drum rotates they form an angle of 90 degrees with the soil surface, while the plate with the blade is made in the U-shape, mounted on the frame at an acute angle to the soil surface, and the sharpened edge is directed towards the drum, and at the points of connection with the frame the plate has grooves for adjusting the depth of loosening soil and weed roots, while the handle of the cultivator is fixed on the frame with the possibility of changing its position relative to the vertical axis to 20 ° and is made with a bend, and on the axis of the frame, trapezoid is installed on both sides of the drum shaped protective plates with the ability to adjust the height of the position relative to the soil surface.

The utility model is illustrated by drawings:

In FIG. 1 shows a general view of a cultivator without trapezoidal protective plates;

in FIG. 2 - shows the assembly diagram of the cultivator;

in FIG. 3 is a side view;

in FIG. 4 - top view

in FIG. 5 - front view

in FIG. 6 is a general view in a perspective view.

The claimed utility model is a tool for gardeners and gardeners, allowing with minimal effort to quickly and efficiently process any household plot. The tool combines the functions of a combine and cultivator. A metal drum with special blades installed in a special way, when moving loosens the soil, breaking the hardened lumps of earth. A special adjustable plate with a blade mounted behind the drum loosens the soil at a depth of 3 to 8 cm, while cutting the roots of the weeds. During the primary tillage, the user reciprocatingly easily processes the entire infield without any back pressure. Previously treated soil is loosened and cleared of weeds. The width of the processing strip is 35-40 cm, the depth adjustable by the blade is up to 8 cm.

Additional loosening of the soil occurs when the drum moves with a plate with a blade deepened into the soil at the same time. Due to the installation of the plate at an acute angle to the surface of the earth and the blade, the plate easily penetrates into the soil to a specified depth, and, while cutting, it simultaneously raises the soil layer, which the drum blades alternately pick up and move it through the air to a height of 10-15 cm, for rotational moment of the drum.

For convenient use of the tool, it is possible to change the angle of the direction of the handle, for the absence of the need to walk on the excavated. The range of deviation from the vertical axis is 20 degrees.

Thus, when working with a cultivator-ripper, the user is able to move parallel to the processing strip without stepping on it.

The harvester-ripper contains a frame 1, a working body 2 mounted on the axis 3 of the frame 1 with rotation, placed on the frame 1 behind the working body, a plate 4 with a blade 5 for cutting weed roots and loosening the soil, a handle 6 connected to the frame 1 and trapezoidal protective plates 7.

The working body 2 is made in the form of a metal drum and is intended for loosening the soil and breaking down hardened lumps of earth.

The lateral sides of the drum 2 are connected by blades 8 in the form of parallel mounted plates protruding beyond the side surface of the sides, and the blades 8 are installed so that when the drum rotates, they form an angle of 90 degrees with the soil surface, while the soil is crushed under the weight of the tool.

The plate 4 for cutting the roots of the weeds and loosening the soil is made in a U-shape, connected to the frame 1 by the ends and has grooves 9 on them for setting it to the required depth of loosening the soil and cutting the roots of the weeds.

Part of the plate 4 parallel to the drum 2 is a blade with a sharpened edge, and the plate 4 on the frame 1 is fixed at an acute angle, the blade 5 is attached to the soil surface, and the sharpened edge is towards the drum 2. The plate 4 performs its function simultaneously with the movement of the drum 2 on the soil surface , while the depth of cultivation can be set up to 8 cm.

For the convenience of using the cultivator and the ability to move parallel to the processing strip, i.e. do not walk along the excavated one, in the upper part of the frame 1 there is a groove 10 for installing the handle 6 with the possibility of changing its position relative to the vertical axis to 20 °. While the handle 6 is made with a bend to increase the angle of tillage and easy entry of the blade 5 of the plate 4 into the surface to be treated.

In addition, the cultivator is equipped with trapezoidal protective plates 7 mounted on the axis 3 on both sides of the drum 2 with the possibility of adjusting the height relative to the soil surface using grooves 11. The protective plates 7 are designed to protect against damage to plant stems during inter-row cultivation of the soil with blades 8 of the drum 2 They are made removable, so the tool can be used both with them and without them and installed as necessary.

Combine ripper works as follows.

The assembled handle 5 is fixed in the required direction (vertically straight or vertically to the side) with a bolt and a wing nut. Set the plate 4 with the blade 5 to the required depth and also fix its position with bolts.

The user, holding the handle 6 of the cultivator at the level of the belt, moves forward. Drum 2 is set in motion when moving loosens the soil, breaking the hardened lumps of earth. A plate with a blade mounted behind the drum loosens the soil at a depth of 3 to 8 cm, while cutting the roots of the weeds. During the primary tillage, the user translates back and forth, easily processes the entire infield without any load on the back. Previously treated soil is loosened and cleaned of weeds by a combine-cultivator.

Thus, the claimed utility model is simple and reliable in design, reduces the cost of labor and energy of the user when performing work, is universal and convenient to use.
