Description

The technical field to which the utility model relates.

The utility model relates to the field of agricultural engineering, in particular to the tillage parts of the working bodies of tillage machines.

State of the art

A lancet paw of a cultivator is known, including a right and left console and a pointed nose with a rigidly fixed base, the console of which has a surfacing of wear-resistant material with its penetration through the entire depth and filling of the technological groove with the electrode material made on the back side (see Patent RU 694112. Worker cultivator's organ / Yu.V. Verzilov, G.P. Myasoedov, V.M. Koltunov, G.A. Dunin, E.L. Kondratyev, and N.D. Modin, Claimed June 14, 74; published October 10, 79).

The disadvantage of this cultivating paw is the inability to control the width of the grip.

A well-known paw of a cultivator, including a base, right and left consoles with pointed edges, the blade of which has a surfacing of wear-resistant material (see Patent RU No. 2216138 C2. Cultivating paw / Strebkov SV., Bulavin SA, Makarenko AN, Gorbatov S.A. Claimed 06.15.2001; published 11.20.2003).

The disadvantages of such a cultivating paw should be considered the preservation of the width of the grip, the complexity of manufacturing.

The closest in technical essence and the achieved positive effect and adopted by the authors for the prototype is the design of the cultivator leg, which contains the base of the leg, adjusting bolts, right and left consoles with sharp edges and a pointed nose rigidly connected to the base, made collapsible with the possibility of regulation the width of the grip (see US patent No. 2396132 Cultivator tool / Shaffer Larkin R / United States, A01B 35/26. publ. 05.03.1946).

The disadvantages of such a cultivating paw should be considered:

- design complexity due to the large number of components;

- the complexity of its settings in preparation for work and adjustment during operation due to the large number of adjustable parameters;

- fastening the blades with the help of pins pos. 22 and adjusting bolts pos. 27 complicate their replacement.

Utility Model Disclosure

A cultivator lancet with an adjustable grip width and a vertical plane of symmetry, including a base, right and left consoles with pointed edges and a pointed nose rigidly connected to the base, each of the consoles is made of two, spaced apart at opposite ends of the consoles, circular bolt holes, with the possibility of temporary fastening to each of the consoles of a flat steel element - a wing, made in the form of an isosceles triangle with a rounded top, with pointed lateral edges and two bolt holes along the axis of symmetry, the distances between which are aligned with the holes in the consoles, and the hole at the rounded wing tip is made circular, and the hole remote from the wing tip is made in the form of a circular arc with the center of the radius of the arc axis in the center of the circular hole.

Adjustment of the working width for tillage is necessary in order to control weeds and for each crop due to changes in row spacing during sowing and tillage when caring for row crops. Changing the Spacing of the Aisle depending on the technology of cultivating crops is reduced to loosening the upper and lower wing mounting bolts and adjusting according to the pattern to achieve the desired working width. When the cutting edge of the working edge of the wings is worn, they are rearranged on the opposite side of the console of the cultivator leg, then the not worn part of the wings becomes the working edge.

The technical result that can be achieved using the proposed utility model is to control the width of the grip, as well as reduce the time to restore the working state of the cultivator paws.

Utility Model Implementation

Lancet paw of a cultivator with a variable working width and a vertical plane of symmetry (Fig. 1), including a base 1, a right 2 and a left 3 console with pointed edges 4 and 5 and a pointed nose 6 rigidly connected to the base 1, two consoles are made on each spaced at opposite ends of the consoles, circular holes 7 and 8 for the bolts (bolts are not shown in the figures), with the possibility of temporary fastening to each of the consoles of a flat steel element - wing 9 (Fig. 2), made in the form of an isosceles triangle with a rounded apex 10, with pointed lateral edges 11 and 12 and two holes 13 and 14 for bolts along the symmetry axis, the distances between which are aligned with the holes 7 in the consoles 2 and 3, the hole at the rounded apex of the wing is circular, and remote from the apex of the wing the hole 14 coaxially with the hole 8 is made in the form of an arc of a circle with the center of the radius of the axis of the arc in the center of the circular hole 13 coaxial with the hole 7.

To change the width of the grip during tillage in order to control weeds and to cultivate various crops, wings 9 are installed on the right 2 and left 3 console of the cultivating paw. Additional wings are attached using bolts and nuts (bolts and nuts are not shown in the figures) when the alignment of the hole 8 on the consoles with the hole 14 of the wing and the holes of the console 7 with the circular hole of the wing 13.

Adjustment of the working width for tillage is necessary in order to control weeds and for each crop due to changes in row spacing during sowing and tillage when caring for row crops. Changing the row spacing depending on the technology of cultivating crops reduces to loosening the upper and lower wing mounting bolts (not shown in the figure) and adjusting according to the template to achieve the desired working width. When the cutting edge of the working edge 11 or 12 of the wings 9 is worn, they are rearranged on the opposite side of the console of the cultivator leg, then the not worn part of the wings becomes the working edge.

This design of the lancet paw of the cultivator allows you to adjust the width of the working surface in accordance with agrotechnical requirements, as well as to restore the working capacity of the cultivator paw in a short period of time by not completely replacing it, but by rearranging mutually replaceable flat steel elements - wings.

The proposed utility model allows due to the simplicity of the design to simply adjust the width of the row spacing, reduces the setup time of the lancet paws of the cultivator and increases the overhaul period by using additional flat steel elements - wings with the possibility of reinstalling them from right to left console as sharpening changes and wear of the cutting edge of the wing.
