Abstract

The utility model relates to agriculture. The paw (2) of the cultivator contains a holder (1) and wings (3) of the paw (2). In the fore part of the paw (2), along the butt line of the wings (3), there is a groove with an open slot for a ripper (6), made with a base in the form of a platform (7) copying the groove. The width and thickness of the groove is greater than the width and thickness of the platform (7) of the ripper (6). The length of the platform (7) is equal to the length of the groove and half the length of the ripper (6), which copies the surface of the share (2) to the holder (1). The height of the cultivator (6), made in an oval shape, is equal to the depth of tillage. Wings (3) paws (2) are made with a sharp angle of inclination of the cutting edge (4). The ends of the wings (3) of the paw (2) are bent down at a right angle, forming slots (8), the height of which is half the depth of tillage. EFFECT: increased stability of the movement of the unit and the quality of tillage, expansion of functionality. 6ill.

Description

The utility model relates to agricultural engineering, namely to the working bodies of tillage machines.

A device consisting of a rack, a flexible element such as a string is known. One end of the flexible element is attached to the foot, and the other - to the bracket located on the rack through a spring and an adjusting screw with a nut (SU No. 536768, IPC A01B 35/26,1976).

A disadvantage of the known device is the increase in the traction resistance of the working body due to excessive accumulation of plant residues on a flexible element such as a string.

Closest to the claimed device is a cultivator paw containing a holder, two wings with blades coated with a wear-resistant layer and a bow (p. RU No. 2714843, IPC A01B 35/20, 2020).

The disadvantage of the known design paws of the cultivator is a high traction resistance, low quality processing, unstable movement of the unit.

The objective of the utility model is to increase the stability of the movement of the unit and the quality of tillage, the expansion of functionality.

The stated technical problem is achieved by the fact that the cultivator paw containing the holder and wings of the paw, according to the utility model, in the fore part of the paw along the butt line of the wings, a groove is made with an open slot for a ripper, made with a base in the form of a platform copying the groove, the width and thickness of the groove is greater width and thickness of the platform of the ripper, the length of the platform is equal to the length of the groove and half the length of the ripper that copies the surface of the share to the holder, the height of the oval-shaped ripper is equal to the depth of tillage, the ends of the wings of the share are bent down at a right angle, forming slots, the height of which is twice less depth of tillage, with a sharp angle of inclination of the cutting edge.

The utility model is illustrated by drawings.

In FIG. 1 shows a 3D cultivator share, general view; in fig. 2 - the same, side view; in fig. 3 - the same, front view; in fig. 4 – the same, top view; in fig. 5 - paw; fig. 6 - ripper.

The paw of the cultivator contains a holder 1, a paw 2, two wings 3 from the cutting edge 4. In the fore part of the paw 2, along the butt line of the wings, a groove 5 is made with an open slot on top for the ripper 6, made with a base in the form of a platform 7 copying the groove 5.

The width and thickness of the groove 5 is greater than the width and thickness of the platform 7 of the ripper 6. The length of the platform 7 is equal to the length of the groove 5 and is half the length of the lower part of the ripper 6, which copies the upper surface of the paw 2 to the holder 1.

The height of the ripper 6, the upper part of which is oval, is equal to the depth of tillage. The ends of the wings of the paw 2 are bent down at a right angle, forming slots 8, the height of which is half the depth of tillage.

Paw cultivator works as follows.

Before starting the operation of the device, the angle of crumbling of the wings 3 of the paw 2 is set to zero. The platform 7 of the ripper 6 is inserted into the groove 5 with an open slot.

When the device moves, the paw 2 cuts the soil layer with the wings 3 with a deposited layer. The wings 3 of the paw 2 have a sharpened cutting edge 4 with a sharp angle of inclination, which ensures complete cutting of weed roots.

The slotter 8 cuts a slot in the soil to a depth that is half the depth of tillage.

The ripper 6 during operation is under the pressure of the soil and rests against the back wall of position 5. It cannot fall out of its place, although it is not fixed in the groove 5.

The presence of two slotters 8 at the ends of the wings of the paw 2 and the ripper 6 in the center ensure the stability of the unit.

In one pass, the unit simultaneously performs several operations at once: cutting weeds, loosening and slotting the soil.

The use of a cultivator paw will improve the quality of tillage and the stability of the unit.

Claims (1)

Paw of the cultivator containing the holder and wings of the paw, characterized in that in the nose of the paw along the butt line of the wings there is a groove with an open slot for the ripper, made with a base in the form of a platform copying the groove, the width and thickness of the groove is greater than the width and thickness of the ripper platform, the length the platform is equal to the length of the groove and half the length of the ripper that copies the surface of the share to the holder, the height of the oval-shaped ripper is equal to the depth of tillage, the wings of the share are made with a sharp cutting edge angle, and the ends of the wings of the share are bent down at a right angle, forming slots , the height of which is half the depth of tillage.
