Description

Technical field

The utility model relates to agricultural machinery, garden tools, and can be used for simultaneous loosening of the soil and the selection of grass material.

State of the art

A known device is a manual rake (Patent No. RU 2606281,

IPC A01D7 / 05 (2006.01) Published: 01/10/2017 Bull. No. 1), containing a handle and a working body in the form of a hinge connected to a holder having a U-shaped cross section, and equipped with a shutter in the form of a base flanged along the outer contour of the lower part of the holder, in which holes for teeth and locking pins are made, while screw clamps are installed on the ends of the shutter, interacting with the holder, and the handle is made of at least two telescopic connected pipes, one of which is connected to the holder of the working body by means of removable rods and clamps [1].

The disadvantage of this device is the lack of the possibility of simultaneous loosening of the soil and the selection of grass material in one motion.

Closest to the claimed technical solution is (Patent No. RU 68836, IPC A01B1 / 00 (2006.01), A01D7 / 00 (2006.01), Published: December 10, 2007 Bull. No. 34). A rake broom containing a head made of fan-shaped working elements, a means of connecting the handle to the head - a holder, the working elements being rods and teeth made curved on one side, and the holder has an insert that can be equipped with fastening means to hold additional elements a rake, the function of holding the working elements in the holder is performed by a nail passing through the groove or grooves-openings of the working elements, fixed in the holes of the holder, and also with the fact that a child, which can be made in the form of a straight bar, or in the form of an arc, and can also be equipped with stiffeners and can additionally be equipped with a holder [2].

The disadvantage of this device is the lack of the possibility of simultaneous loosening of the soil and the selection of grass material in one motion.

The proposed technical solution allows to eliminate these disadvantages.

Utility Model Disclosure

The technical result is the simultaneous loosening of the soil and the selection of grass material in one motion.

The present technical result is achieved in a double-row rake device containing a handle, a comb with teeth and a holder with a conical fastening of the handle, moreover, a connecting plate is attached to the rake holder, onto which the holder of the fan-shaped rake is fixed, the teeth of the latter are laid on the rake comb and pressed with a patch plate fixed with self-tapping screws to the comb beam.

Distinctive features are:

a connecting plate is attached to the rake holder, onto which the holder of the fan-shaped rake is fixed, which ensures the reliability of the structure and reduces the likelihood of breakage while loosening the soil and selecting grass material in one motion;

the teeth of the fan-shaped rake are laid on the rake comb and pressed with a patch plate fixed with screws to the comb beam, which reduces the likelihood of displacement of the fan-shaped teeth and improves the quality of simultaneous loosening of the soil and selection of grass material in one motion.

Comparison of the proposed solutions with analogues and prototype did not allow to identify in them the features that distinguish the claimed solution, which allows us to conclude that the criterion of "novelty".

Brief Description of the Drawings

In Fig. 1, a profile view of a double row rake is shown, including: 1 - a holder with a conical fastening of the handle; 2 - comb with teeth; 4 - fan-shaped teeth; 5 - cuttings; 6 - overlay; 7 - a connecting plate.

In Fig.2 shows a horizontal view, where: 1 - holder with a cone-shaped attachment of the handle; 2 - comb with teeth; 3 - holder fan-shaped teeth; 4 - fan-shaped teeth; 7 - a connecting plate.

Utility Model Implementation

Double-row rakes are made as follows.

The manufacturing technology of the proposed device is similar to the manufacturing technology of known devices [3].

A connecting plate 7 is welded to the rake holder 1, the holder of the fan-shaped rake 3 is fixed on it with bolts or screws, the teeth 4 of which are laid on the rake 2 comb and pressed by the lining 6 fixed by self-tapping screws to the comb beam 2 (not shown in Fig.).

Double row rake ready to go.

A comb with teeth 2 with high productivity rakes weeds, roots, grass from the soil, and the teeth of a fan-shaped rake 4 collect them in a heap with one movement of the device on itself.

Double-row rakes increase the productivity of the labor that works by them and reduce its fatigue.
