RU139150U1 - CULTIVATOR ARROW FEET - Google Patents

Abstract

The cultivator lancet paw containing the base of the paw, mounting bolts, characterized in that the paw is collapsible and consists of a nose fixed to the base of the paw with bolts of fastening to the rack, and two blades that are inserted into the grooves of the base of the paw and secured with bolts of the blade foot basis.

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. The paw of the cultivator is designed so that when the blunting of its working surfaces does not change the entire paw of the cultivator, but only its working organs: blades and toe.

State of the art

Known lancet cultivator paw, the blade of which has a surfacing of wear-resistant material with its penetration to the full depth and filling with the electrode material a technological groove made from the back side (see Patent RU No. 694112. Working body of the cultivator / Yu.V. Verzilov, G.P. .Myasoedov, V.M.Koltunov, G.A. Dunin, E.L. Kondratyev and N.D. Modin. Declared June 14, 74; published October 30, 79).

The disadvantage of this cultivating paw is the presence of a protruding volume of the deposited metal beyond the geometric parameters established by the agrotechnical conditions, which will impede the movement of the cultivator paw, increasing traction resistance and increasing the energy performance of the cultivating unit. In addition, when the working surfaces of the cutting edge of this leg of the cultivator are worn, it is necessary to completely change it.

Known cultivator leg, consisting of a ploughshare with a cutting edge, the blade of which has a surfacing of wear-resistant material (see Patent RU No. 2216138 C2. Cultivator leg / Ogrebkov 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:

- a sufficiently high complexity of the process;

- requires the use of a special deposited wear-resistant material;

- there is some change in the geometry of the paw; the availability of specialized equipment;

- when the working surfaces of the cutting edge of this leg of the cultivator are worn, it is necessary to completely change it.

Closest to the claimed is the design of the cultivator paw with a replaceable nose and pads (kps-4; ksg-5), which contains the base of the paw, mounting bolts, pads on the nose and wings of the cultivator (see Pat. 49298 Ukraine, IPC АВВ 33 / 00. Paw of a cultivator / Moskalevich V.Yu., Babshky L.F., Tarasenko BI; applicant i patent applicant national university biopecypical i nature conservation Ukraine.

The disadvantages of such a cultivating paw should be considered:

- individual bolts securing the toe pads of the cultivator paw, which complicates its design, and increases its mass;

- massive dimensions of the pads on the wings, which significantly increases the mass of the cultivator paws.

Utility Model Disclosure

The objective of the proposed utility model is to increase the maintainability of the paws of the cultivator and reduce the cost of restoring its performance.

The technical result that can be achieved using the proposed utility model is to reduce the cost of restoration or replacement of the cultivator paws, increase its practicality and improve the quality of soil treatment.

The technical result is achieved using the lancet paws of the cultivator containing the base of the paw, bolts of attachment to the rack of the cultivator, while it additionally contains the nose, blades and bolts of the blades to the base of the paw, while the nose and base of the paw are mounted with bolts of attachment to the rack of the cultivator.

Brief Description of the Drawings

In Fig 1. - lancet paw of a cultivator with replaceable working bodies assembled.

In Fig 2. - the same thing in the analysis.

Utility Model Implementation

The lancet paw of the cultivator consists of a base of 1 paw, bolts 2 of the mount, nose 3, blades 4, which are inserted into the grooves (not shown in Fig.) Of the base of 1 paw and are fastened with bolts 5 of the blade.

The arrow foot of the cultivator works as follows:

In the process of cultivation, the lancet paw of the cultivator moves in the upper layer of the earth, and cuts weeds with working edges. When the working edges of the lancet paws of the cultivator wear, the bolts 2 of the attachment to the cultivator strut (not shown in FIG.) Of the base of the paw 1 are wound, and the nose 3 is changed to a new one, as well as the bolts 5 of the blade attachment are unscrewed and the blades are removed 4. Then new blades 4 are installed in grooves of the base 1 paws, bolted 5 bolts mounting blades. After that, the nose 3 and the base 1 of the paw with the blades 4 already installed are attached to the cultivator strut using the bolts 2 of the mount.

This design of the lancet paw of the cultivator allows you to restore the efficiency of the cultivator paw by not completely replacing it, but replacing only its blunt parts of the nose and blades, which can significantly extend the life of the base. Due to this, the cost of replacing worn working bodies is significantly reduced.

The proposed utility model in comparison with the prototype and other well-known technical solutions has the following advantages:

- allows you to significantly extend the operating time of the base of the paw;

- reduces the cost of restoring the health of the lancet paws of the cultivator;

- allows you to use cheaper steel grades for making the base of the paw;

- allows you to differentially change, as necessary, worn working bodies (nose, blades);
