RU200187U1 - TILLAGE TOOL - Google Patents

Abstract

The utility model can be used in the development of new and modernization of previously produced plows with the replacement of conventional moldboard, non-moldboard stands for the proposed plow stand.

The presence of a disc corrugated knife of large diameter allows you to cut a gap in the soil for the entire or most of the depth of soil cultivation by the main stand, the presence of an inclined share allows you to direct part of the excess atmospheric precipitation along the plow sole into the gap from the main stand. The pendulum arm of the circular cutter avoids damage to the cutter when there are obstacles. 6 ill.

Description

The utility model relates to the field of agricultural engineering, to the working bodies of implements for the main tillage.

Known combined plow containing a frame with mounted on it without moldboard rippers and moldboard bodies of the upper tier (agricultural machinery cat. T.1 "Equipment for plant growing" M. FGNU "Rosinformagrotech" 2005 with 157).

This arrangement of working bodies on the plow frame leads to increased clogging with soil blocks and plant residues under certain soil and climatic conditions.

Also known is the working body of the plow, containing mounted on the frame moldboard bodies, each of which consists of a rack, a share, a blade, a field board. Behind each moldboard body, below its plowshare, rippers are installed, adjustable in height (Kharlansky V.M., Gorbachev N.V. / Agricultural machines. M. Kolos 2004, 25 p.).

The technical disadvantage of the plow with these working bodies is an increase in soil resistance due to the need for the ripper to destroy the "plow sole" from the forward located dump body.

Also known is the working body of the subsoiler, patent RU 2679035 C1. This working body has a vertical stand and a curved lower part extended forward with a swept paw fixed at the end. This subsoiler allows you to work the soil to a depth sufficient to destroy the nodes of the root system of perennial weeds.

The disadvantage of this subsoiler is the increased soil resistance and the inability to moldboard the upper layer of the soil.

To reduce soil resistance, working bodies are proposed that work together, this is a curved stand with a pointed lower part brought forward, on which a swept bit made of wear-resistant material is installed. A bracket extended far forward is attached to the main rack by welding. A pendulum arm of a large-diameter circular knife is attached to the main rack on an axle welded into the rack. The pendulum arm is supported by springs on the strut bracket. The circular knife has a corrugated ring made of wear-resistant steel, with which it cuts a slot in the soil for the passage of the rack.

For non-moldboard or moldboard cultivation of the upper layer of the soil, it is proposed to install the plowshare and blade mounting brackets on the main rack, and the front part of the plowshare treats the soil a few centimeters deeper than the rear part of the plowshare, in this case the excess moisture of atmospheric precipitation will be directed along the “plow sole” in the trail from the main rack.

in fig. 2 shows a sketch "right side view" of this kit;

in fig. 3 shows a sketch "front view" of a set with an installed share;

in fig. 5 shows a sketch "front view" of a set with a share and a blade;

in fig. 6 shows a sketch "right side view" of a set with a share and a blade.

The set consists of a curved main stand 1; a swept bit 2 made of wear-resistant material is installed on its pointed lower part brought forward. The leading edge of the pillar 1 from the crown 2 and slightly above the depth of soil cultivation has a surfacing 3 made of a wear-resistant welding alloy. On the upper part of the rack 1, a bracket 4 is welded and the axle 5 of the pendulum arm 6 of the axle 7 of the circular knife 8 with a corrugated ring 9 is welded in. Shock-absorbing springs 10 are installed between the bracket 4 and the pendulum arm 6, the downward stroke of the pendulum arm 6 is limited by cables 11 from self-dismantling of the springs.

For the processing of the upper layer of the soil, a ploughshare 12 and a blade 13 are installed on the main stand 1.

Soil cultivation is as follows.

The disk knife 8, under the action of the springs 10, is buried in the soil and with a corrugated ring 9 cuts a gap (for the entire or most of the depth of soil cultivation), a stand 1 follows this gap in the soil, the crown 2 loosens the soil at great depth.

стойки 1 и коронки 2.Mouldboard or moldboard tillage to the required shallower depth is produced by the share 12 and the blade 13, which can be rearranged to change the depth along the strut 1. The share 12 is installed with a deeper front part with a toe and a few centimeters less recessed rear part, formed by an inclined "plow sole »Directs atmospheric moisture into the slot of the circular cutter

posts 1 and crowns 2.

The use of a large-diameter circular knife and a curved rack with an arrow-shaped crown in the set allows processing the soil (with a decrease in the required tractive effort and MTA fuel consumption) to the depth necessary to combat perennial weeds.

Claims (1)

Tillage tool consisting of a disc coulter and a curved rack with an arrow-shaped crown on the pointed lower end of the rack, which is characterized in that the disc coulter is mounted on a pendulum arm with shock-absorbing springs, which rest on a bracket attached to the upper part of the curved rack, on which an additional share and a moldboard are installed for soil cultivation to a shallower depth relative to the arrow-shaped crown, and the front part of the share cultivates the soil deeper than its rear part.
