RU2654726C2 - Hand horticultural soil disrupturer - Google Patents

Abstract

FIELD: agriculture.

SUBSTANCE: invention can be used in horticultural activities. Hand horticultural soil disrupturer for soil loosening without moving and overturn of the formation includes a bar with a movable collar handle, mounted on the bar with the possibility of moving along its length, a lock of their mutual position, pressure rack with teeth. All details of the disrupturer are located in the same plane. Teeth are made of different lengths. Teeth are located on the pressure rack in parallel and symmetrical to the axis of the bar, and the long ones are closer to the axis of the bar, and short ones - to the periphery of the pressure rack.

EFFECT: such an invention reduces the physical loads and number of necessary operations, ensures a high quality of loosening without formation overturn.

Description

The invention relates to devices and devices for loosening the soil without overturning and moving the formation in a garden economy.

Known ripper called "tornado" (http://goo.gl/JVjfXU), which is a rod with handles for its rotation, in the lower part of which are specially curved teeth for screwing into the soil. In this case, the destruction of the reservoir and its movement. When removing the cultivator, the soil is ejected to the surface.

The disadvantages of the cultivator are significant efforts when screwing in, extracting with the release of soil, requiring additional harrowing.

Known cultivator-cultivator manual (http://goo.gl/Ge6HsR).

The base of the working part is a flange with a short axial rod. 3 tool steel knives are welded to it 12 cm long, 4 cm wide and 3 mm thick. A half-inch diameter water socket is welded to the stem. A pipe is wrapped in the sleeve, at which a thread is cut at both ends. It performs the function of a shank. A water tee is screwed onto the free end of this pipe. Two short tubes are screwed into it - this is the handle-gate.

Operating procedure. It is necessary to take the drill with both hands by the handle, to raise it 20-30 cm above the ground and force it to stick vertically into the soil. Then rotate 360 °. Knives will cut grass roots. The drill is lifted and stuck into the soil again, next to the treated area, rotated around the axis. So repeat many times.

Disadvantages - massiveness, significant physical exertion when stuck in the soil, loosening only its surface layer.

The closest in design to the proposed device are ordinary household forks, consisting of the pitchfork itself with curved teeth, planted at a convenient angle for work on the stalk, which can be used for digging the soil. The pitchfork teeth easily enter the soil and are removed from it with a partial or complete overturn of the formation in the form of clods of various sizes, requiring additional crushing and harrowing, which is a significant drawback when using them.

The purpose of the invention is the reduction of physical activity with high quality loosening.

The proposed cultivator is shown in Fig. 1. It consists of a grip-handle 1, a rod 2, a pressure rail 3, teeth 4 on the pressure rail and a latch 5. All parts are located in one plane. The teeth are made of different lengths, mounted parallel and symmetrically to the axis of the rod, long closer to the axis of the rod, short to the periphery of the pressure rail.

A ripper is used as follows.

It is installed vertically in the right place of the bed, by pressing the foot on the rail press 3 teeth 4 are immersed in the soil, turning the handle-handle 1 around the axis of the rod in any direction (clockwise or counterclockwise) loosens, then removes the cultivator from the soil. A hemispherical shape well is prepared, ready for sowing seeds or planting seedlings. To achieve a positive result, half the cultivator turnover is sufficient. The optimal dimensions of the details of the cultivator: the width of the pressure rail 220 mm, the length of the internal teeth 180-220 mm, diameter 10-12 mm, the outer teeth 80-100 mm long and 10-12 mm in diameter. The distance between the teeth is 60-70 mm. The length of the rod is set by vertical movement of the handle-collar 1 and the latch 5. The mass of the ripper in assembled form from tubes of square section 20 × 20 mm and 25 × 25 mm less than 2 kg

Claims (1)

A manual garden cultivator for loosening the soil without moving and turning the bed, including a bar with a movable handle-handle, mounted on the bar with the ability to move along its length, a latch for their relative position, a pressure rail with teeth, while reducing physical stress and the number of operations with high quality loosening, all the details of the cultivator are located in the same plane, the teeth are made of different lengths, are located on the pressure rail parallel and symmetrically to the axis of the rod, and the longer ones are closer to the axis rods, and short - to the periphery of the pressure rail.
