Abstract

FIELD: agriculture.

SUBSTANCE: present invention pertains to agricultural engineering for cultivating or loosening soil, as well as weeding and ridging crops, leveling a land plot and laying out planting furrows at a country house, vegetable garden and other similar land plots. The manual tillage instrument comprises a frame, in the bottom part of which there is a balancing wheel and handles in the upper part. In the middle part of the frame there is a mounting for a detachable tillage instrument, and there is a connecting rod. The bottom part of the frame has a horizontal section, on which a balance wheel with smaller diameter is put and a mounting for the detachable instrument, which is provided with clamping plates for regulating position of the detachable instrument on the horizontal. The upper part of the frame is at an angle to the vertical. In the upper part of the frame there are two cross-bars, on the lower one of which is fixed a threaded control bar, joined to the mounting of the detachable instrument through the detachable instrument, which in turn, is fitted on the cross-bar with possibility of regulating position on the vertical. The manual instrument is provided with detachable working tools and has small dimensions, which simplifies transportation.

EFFECT: reduced manual effort when tilling; simplification of tilling technology; increased labour efficiency.

Description

The invention relates to agricultural machinery for cultivating or loosening the soil, as well as for weeding and hilling crops, removing weeds, leveling the land and marking planting furrows in the country house, garden and other similar land plots.

Known hand tools for tillage (patent FR No. 2888084, A01B 1/06, 01/12/2007; patent RU No. 2095950, A01B 1/06, 11/20/1997). These hand tools consist of a frame with handles on which a large diameter wheel and a working tool for cultivating the soil are fixed. But the capabilities of these devices are limited, because similar designs can only be used for weeding and cultivating the soil.

The closest technical solution of the known is a manual tillage complex (patent RU No. 2171556, A01B 1/06, 08/10/2001), which is used for hilling garden crops, cultivating the soil, weeding row spacings and cutting furrows in the soil. The structure of the tillage complex includes a frame, in the lower part of which a support wheel of a large diameter is installed, and in the upper part there is a handle, as well as a unit for attaching a replaceable tillage tool.

The disadvantage of this device, as above, is the inefficient use of human effort, large transport dimensions. In addition, the high location of the center of gravity of the device requires an increase in the effective force that a person can transmit through the frame to the working bodies.

An object of the invention is to increase the efficiency of using tillage tools, expanding its technical capabilities.

The technical result of the use of the proposed tillage tool is to reduce the physical effort of a person in the processing of soil and crops, to improve and simplify the technology of tillage in manual processing, to increase labor productivity, as well as to reduce transport dimensions and simplify the conditions for transporting the tool.

The specified technical result is achieved due to the fact that the manual tillage tool includes a frame, in the lower part of which a support wheel is installed, in the upper part there are handles, a knot for attaching a removable working tool, and a rod, and the lower part of the frame has a horizontal section on which are placed a support wheel of small diameter and an attachment point for an interchangeable tool, which is equipped with clamping bars for adjusting the horizontal position of the interchangeable tool. The upper part of the frame is located at an angle to the vertical. In the upper part of the frame there are two cross-members, on the lower of which a rod with a thread is movably fixed, which provides the possibility of adjusting the angle of inclination of the wearer, associated with a removable working tool, which is mounted on the rod with the possibility of vertical adjustment. The hand tool is equipped with interchangeable working tools. For example:

- pololnik, made in the form of a triangular steel plate, mounted on a vertical holder that moves underground by pruning the roots of plants;

- hiller, made in the form of a curved plate mounted on two vertical holders;

- a knife for leveling the soil, made in the form of a rectangular steel plate with a curved bottom edge mounted on one vertical holder;

- a marker for landing furrows, made in the form of a corner, with holes on the upper shelf, in which the required number of rods are pointed, pointed at one end, fixed with two holders on the lower cross member of the upper part of the frame;

- a rake installed using two holders, the holders being fixed one on the upper and the other on the lower crossbar of the upper part of the frame and are interconnected.

The invention is illustrated by drawings. Figure 1 shows a General view of a manual tillage tool, figure 2 - a knife for leveling the soil, figure 3 - marker for furrows, figure 4 - hiller.

A manual tillage tool consists of such basic elements as frame 1, which has two sections - the lower horizontal section and the upper one, located at an angle to the vertical. On the frame 1 there is a rod with a thread 2 and cross members 3 and 4, a support wheel 5, a handle 6, as well as a fastener for the tool 7 with clamping bars 8 for adjusting the horizontal position of the tool. On the rod 2, a removable working tool 9 and an additional removable working tool 10 are mounted and fixed using the attachment unit 7. As an interchangeable working tool 9, a hiller, pololnik, a knife for leveling the soil, etc. can be used. As a replaceable working tool 10 can be used a tool for making furrows, rakes, etc.

Manual tillage tool works as follows. Depending on the growth and physical capabilities of a person, the degree of preliminary cultivation of the soil, as well as the required treatment regime (cultivation, hilling, weeding, etc.), a removable working tool 9 is installed on the rod 2 and fixed using the attachment unit 7. Manual tillage tool it is taken by the person with two hands on the handle 6 and pushed in front of the person, while at the same time you can monitor the quality of the soil and plants without damaging the latter. This design of the tillage tool allows you to reduce the force required for tillage by reducing the dimensions and, accordingly, the weight of the device, as well as by shifting to the bottom of the center of gravity of the device and the maximum possible approximation of the working body to the support wheel.

The small diameter of the support wheel makes the tool more maneuverable and convenient to use. The horizontal section of the frame on which the working body is located allows you to distribute the force transmitted to the working body and the support wheel.

The invention will allow maximum use of the physical capabilities of a person with manual tillage, to improve the quality of tillage and labor productivity.
