Abstract

FIELD OF THE INVENTION The invention relates to agricultural machinery. The aim of the invention is to improve the quality of crumbling soil. The tool consists of a frame 1, support wheels 2, a hinge mechanism 3 and working bodies, made in the form of racks 4 and wings 5 and 6 legs. Wings 5 and 6 of each paw are installed at an obtuse angle to each other, the top of which is directed in the direction opposite to the direction of movement of the gun. One end of each wing 5 and 6 paws is pivotally connected to the uprights 4, the other end of the wing 5 paws is rigidly connected to the adjacent wing 6 paws. The width of the grip of the wing 5 of the foot is greater than the width of the grip of the wing 6, therefore the stability of the movement of the leg is ensured. During the movement of the wings 5 and 6, the legs cut and crush the soil layer. 1 hp f-ly, 4 ill.

FIELD OF THE INVENTION The invention relates to agricultural machinery and, in particular, to tools for soilless tillage.

The purpose of the invention is to improve the quality of soil crumbling.

FIG. 1 shows the instrument, side view; in fig. 2 - the same, top view; in fig. 3 - working body, top view; in fig. 4 shows section A-A in FIG. 3

The tool consists of a frame 1, support tree 2, a hinge mechanism 3, racks 4 of the working parts and wings 5 and 6 of the legs, for example, the archery. Wings 5 and b of each paw are installed at an obtuse angle to each other, the top of which is directed in the direction opposite to the direction of movement of the gun. One end of each wing 5 and 6 of the paw is pivotally connected, for example by means of tie, with the uprights. The other end of the wing 5 paws is rigidly connected with the adjacent wing 6 paws. The width of the grip (L |) of the wing 5 legs is greater than the width of the grip (L2) of the wing 6 adjacent to it, 6 legs.

The tool works as follows.

As the guns move, wings 5 and 6 of the lag penetrate the soil layer, cut it and crumble. The hinged connection of one end of each of the wings 5 and 6 of the paw with the uprights 4 allows the paw to enter the ground at the moment it enters the ground.

minimum angle and keep it constant in working position. Performing one wing of the paw 5 with a wider grip width than the wing 6 ensures the stability of the paw stroke even at the minimum working depth, and with increasing depth of processing the stability of the movement of the paw increases. By placing the wings 5 and 6 at an angle to each other, the apex of which is directed in the direction opposite to the direction of movement of the cannon, the traction resistance is reduced and the quality of crumbling of the soil is improved.

Claims (2)

1. A tool for soilless tillage, containing a frame, support wheels, a hinge mechanism and working bodies having racks and wing legs, characterized in that, in order to improve the quality of crumbling of the soil, the wings of the paw are installed at an obtuse angle to each other, the top of which directed in the direction opposite to the direction of movement of the gun, with one end of each wing of the paw connected to the pivotally hinged, and the other rigidly with the adjacent wing. 2. A tool according to claim 1, characterized in that the width of the grip of one wing of the paw is greater than the width of the grip of the adjacent wing. / T / 1 rQ ABOUT, J3 - / LLF
