The invention relates to agricultural machinery, namely the small mechanical implements for tillage on the farm and market garden plots.

Known cultivator containing the drive of the working body, made in the form of a horizontal shaft with a fixed group of work items, such as cutters, two straps with the brake element and the control levers, characterized in that the actuator is made in the form of a hollow rack on the top flange which is mounted the motor and the inside flange is located a pair of gear wheels, one of which is installed on the shaft of the worm gear located inside the rack, the lower flange which is fixed to the housing, while the cutters are located on two sides relative to the rack, mounted on the shaft of the worm wheel reducer, in addition, the bracket with the brake element and the control levers mounted on the outer lateral surfaces of the rack (RU patent No. 2116014 And 01 In 33/02, publ. 27.07.1998).

The disadvantages of the cultivator are high intensity, lack of maneuverability in cramped conditions, significant dimensions of the working bodies and the weight of the product, difficult transport conditions. In addition, the cultivator used worm gear requiring precision gearing and putting the I to the type of expensive gear.

The present invention is directed to the solution of the technical problem by reducing the metal and size of the drive to ensure the compactness and the possibility of replacing the drive.

The technical result of the invention is to improve performance and usability when processing inaccessible and small areas.

The technical result is achieved in that in the manual cultivator containing hollow rack fixed on the motor associated with the drive shaft, which is mounted through the housing gear is connected with a horizontally positioned shaft, the ends of which facing of a specified enclosure, removable assigned a work item type cutters, as well as the management body of the motor, a hollow strut is made in the form of a straight pipe with a flange on one end for connection to the gears, made conical, and join node on the other end for attachment of an electric drill, an electric motor which is used as a motor for rotation drive shaft made at the ends of the shank for fastening respectively to the spindle of the drill and at the leading bevel gear gear, with the handle electric drill used as the org is to control the motor, and the bolts knives cutters are nuts by going from house of the ends of the horizontal shaft.

These characteristics are essential and interrelated with the formation of a stable set of essential features, sufficient to obtain the desired technical result.

The present invention is illustrated by the specific example shown in the drawings, where:

figure 1 - General view of the hand cultivator cross section;

figure 2 is a view of the figure 1 on the join node;

figure 3 - section a-a of figure 2.

According to the present invention the hand cultivator is a tool for executing a wide variety of agricultural operations:

- continuous tilling the soil;

- the formation of furrows;

treatment row spacing (hoeing, weeding, hilling);

the formation of tree trunks with their embankment;

- digging of pits for planting shrubs and saplings;

- trenching, etc.

The hand cultivator as the frame includes a hollow rack 1 on which is fixed an electric motor associated with the drive shaft 2, which is mounted through the housing 3 gear 4 is connected with a horizontally positioned shaft 5, the ends 6 of which coming from the specified enclosure, removable assigned a work item type cutters. Each of the cut made in the form of six knives 7, three mounted on each side of the disk 8 on which the 7 knives are fastened by bolts 9 to the tangential deviation of backward from the direction of rotation of the cutter.

Hollow rack 1 has a straight pipe with a flange 10 at one end for connection to the frame 3 gears are made conical, and join node on the other end for fastening electric drill 11 (not fully shown), a motor which is used as a motor to rotate the drive shaft 2. The drive shaft 2 is made at the ends of the shank 12 for fastening respectively to the spindle 13 of the electric drill 11 and at the leading gear 14 bevel gear transmission.

Handle electric drill used as the governing body of the motor.

Bolts 9 mounting knives cutters are nuts 15 from exiting the housing ends of the horizontal shaft, which prevents the winding stems of plants on the hub. Each bolt secures simultaneously two knives, and the knives are mounted on the cutters so that when installed on a horizontal shaft these knives were specularly arranged with respect to an axis of a hollow rack 1.

The join node is designed for attaching the drill to the rack. This node includes receiving Cup 16, the calculated internal diameter, the Roux to install the bow of the specific electric drill, for example, the brand IE 1023. Power quality of the electric drill to determine the power of the cultivator. Change the type of drills you can adjust the power to the mills. After installation in the glass with twist drills provide the combination of a groove on the inside of the spindle and the pen on the shank of the cone so tightly drills to sit on the shank of the drive shaft 2. The preload of the shank to the spindle of the drill is provided with a spring 17 located between the two washers 18.

Then turn the grips in the form of l-shaped levers 19, swivel mounted on the rack and having a screw hole 20 in the body. After rotation of the levers in the direction of entry of their free ends through the slots in the wall of the receiving Cup (2, 3) screw bolts 21 with washers 22 through a radial element of the rack in the screw hole of each arm. Fixing levers from rotating. As the free ends of these levers penetrate through the slots in the wall of the Cup into the cavity of the Cup, they interact with the body electric drill, not letting her out of the glass.

The present invention allows to obtain a compact cultivator with a replaceable motor, representing the electric drill. Management cultivator is carried out by analogy with the management drill. Hold the drill stick for the click on the button on the handle of the drill, that provides power to the electric motor, which causes the rotation of the drive shaft and a leading bevel pinion gear. During the rotation of the blades moves cultivator away from the operator. Therefore, the value of the rate of movement and the magnitude of the deepening of the blades in the soil is governed by the amount of resistance on the part of the operator, which he applies to the cultivator in the direction opposite to the direction of movement of the cultivator.

The present invention is industrially applicable, as may be fabricated using well known technologies used in mechanical engineering.

The hand cultivator containing hollow rack fixed on the motor associated with the drive shaft, which is mounted through the housing gear is connected with a horizontally positioned shaft, the ends of which facing of a specified enclosure, removable assigned a work item type cutters, as well as the management body of the motor, characterized in that the hollow strut is made in the form of a straight pipe with a flange on one end for connection to the gears, made conical, and join node on the other end for attachment of an electric drill, an electric motor which is used as nm is the engine for rotation of the drive shaft, performed at the ends of the shank for fastening respectively to the spindle of the drill and at the leading bevel gear gear, with the handle electric drill used as the governing body of the motor and the bolts knives cutters are arranged so that the nuts posted by going from house of the ends of the horizontal shaft.
