Description

It is known to use in agriculture the milling treatment of a feline, especially suitable for heavy clay and clogged peat in pure soils.

The known constructions of the working bodies of milling cultivators, consisting of a section of a milling drum with forced rotation and L-shaped pozhami, create conditions for cutting the soil at variable cutting angles, which degrades the quality of tillage.

The proposed working body of the Milling cultivator allows to improve the quality of tillage during milling, in letters we provide conditions for a better trimming of rhizomes of weeds and eliminates spreading and spraying of the soil. For this, the cutting knives, during tillage, maintain a constant cutting angle in any position, which is achieved by giving them a double movement: rotational along with the drum and reverse curvilinear relative to the drum.

In order to provide the reverse curvilinear movement, the stand of each knife can be made in the form of a first-type raznoplechelny lever, at the long end of which there is a knife, and the short end it interacts with a stationary cam cam copier.

FIG. 1 and 2 respectively show a transverse and longitudinal section of the proposed working body of the milling cultivator.

The working body of the milling cultivator consists of a milling drum section /, on which stands 2 knives 3 are mounted. The stand 2 is made in the form of a two-armed lever of the first kind, carrying knife 3 on a long arm, and a short one interacting with a fixed cam cam 4. In the course of the cultivator, t rotates and moves progressively. Since the knife racks are 3 short

the ends of the rolls through the rollers 5 on the copier 4, then the knives make

avnochny reverse curvilinear motion. The combination of the last Blade Knife 5 with drum 1 creates t & Bff S liQPf knives to keep the cutting angle constant in the thrust position. This circumstance improves the quality of the machining, and contributes to a better trimming of the root and elimination em scattering and spraying soil.

The proposed milling cultivator tool is designed to improve when cutting soil chips with a constant cutting angle during the entire cycle. This is accompanied by a significant reduction in the harmful energy expenditure on the transfer of particles of soil being cut off. At the same time, the night is not scattered and not sprayed from impacts against the safety covers of the milling sections and almost does not participate in repeated cycles, which gives a significant effect of an energy and technological nature, since the treated plants do not fall asleep with soil.

In conclusion of the All-Union Research Institute of Feed, the novelty of the proposed working body of the milling cultivator, its usefulness for agricultural practice and significant (from application) effect of energy and technological nature are noted.

Subject invention

Claims (2)

1. A milling cultivator working organ consisting of a frezbaraban section with forced turning, with L-shaped knives, characterized in that, in order to improve the quality of tillage during milling, better trimming of weeds rhizomes and eliminating scattering and spraying the soil, cutting The knives maintain a constant cutting angle in any position, which is achieved by telling them to double the movement: rotational with the drum and inverse curvilinear with respect to the drum. 2. Working body according to claim 1, characterized in that, in order to provide a constant cutting angle, the knives are given an L-shaped shape, the knife stand being made in the form of a first-class raznoplechey lever, the short arm of which is provided with a knife, and the short one interacts with fixed cam cam milling cutter, providing relative movement of the cutting knife.
