Abstract

The invention relates to agricultural machinery and can be used in machines for the preparation of peat and ameliorated areas, as well as for creating stripes for planting forest crops. The purpose of the invention is to improve the quality of tillage in the lower part of the treated layer. The tillage implement contains a knife milling drum 1 mounted on a frame 10 with side reduction gear 5. At the bottom of the gear housing 5 there is a pointed working body 6 in the form of a pyramid or a cone. The top of the cone is located outside the circumference described by the ends of the cutting elements of the milling drum. When encountering a cone (pyramid), wood inclusions crack or deviate from or to the milling drum, 3 sludge.

Description

The invention relates to soil tillage equipment, more specifically to rotary tillage tools, and is intended for use in the preparation of peat and ameliorated areas, as well as for creating stripes for planting forest crops.

A rotary soil-cultivating tool containing a knife-mounted milling drum mounted on a frame with a horizontal axis of rotation perpendicular to the direction of movement of the tool is known, driving a milling drum with a side reducer, the lower part of the body of which is located below the axis of rotation of the drum, and a fender with a counter knife.

When a side reducer meets with the sun and tree trunks, they are dragged and the traction force increases to move the tool and a dozer effect occurs, which can be eliminated by recessing the milling drum, which adversely affects the quality of the soil in the lower layer of the treated layer.

The purpose of the invention is to improve the quality of tillage in the lower part of the treated layer by reducing the pulling force on the movement of the tillage tool.

This goal is achieved by the fact that a rotary soil-cultivating tool containing a knife milling drum mounted on a frame with a horizontal axis of rotation perpendicular to the direction of movement of the gun, a milling drum drive with a lateral gearbox, the lower part of the body of which is located below the axis of rotation of the drum, and a rotary plate with knife cutter, equipped with a longitudinal vertical plane

an additional working body having a cone shape, the base of which is fixed on the front wall of the lower part of the gearbox housing, and the apex is facing in the direction of movement of the tool and is located outside the circumference described by the ends of the frezbaraban's knives during its rotation.

Figure 1 schematically shows the proposed rotary tillage tool, side view; figure 2 is the same, top view; On fi. Z - section A-A in FIG.

The tillage implement includes a rotary tool, made in the form of a horizontal drum 1 with an average 2 and end 3 cutting elements and located perpendicular to the direction of movement of the tool, the drive

4 with a side gear 5, on the front wall of which in the lower part a pointed working body b is fixed in the form of a cone or pyramid, a baffle plate 7 with a shear knife 8, a mechanism for lifting the working body 9 and a frame 10.

The milling drum 1 has an instrument of rotation opposite to the direction of movement,

0 The lower part of the side gear 5 is located below the axis of the drum and recessed into the soil. The working body 6 is directed by its apex in the direction of movement of the gun. The top of the cone (pyramid) is located behind

5 beyond the circumference described by the ends of the knives of the milling drum above its lower point. Side gearbox

5 together with the working body 6 are placed in a longitudinal-vertical plane. An anti-cutting knife 8 of the baffle plate 7 is located above the cone (pyramid). In the space between them, from the side, from the side of the milling drum, there are end cutting elements3,

5 interacting with a shearing knife when the drum rotates. The lifting mechanism 9 serves to set the working body at different tillage depths and in the transport position.

0 In the process of working the tillage tool, the milling drum, rotating forcibly, cutting, elements mills the soil at a given depth of treatment. At the same time the plate holds

5 live-growing wood when it is crushed on the cutting blade.

Stumps and other woody inclusions, located in the soil in the lane of the additional working body,

0s meet with a cone (pyramid) and split it regardless of the orientation of the wood fibers. A piece of chopped wood, falling into the space between the cone below and the shear knife

5 from above, is cut by cutting elements of the milling drum with a predetermined feed. Another part of the chopped wood remains in the untreated soil layer for later passage, if necessary.

0 according to the technological scheme.

The thrust force on the movement of the tillage tool is reduced by eliminating the dragging of stumps in front of the side wire reducer, since the tip

5 additional working body splits and pushes them. There is no need for recessing of the milling drum and thus improves the quality of tillage in the lower part of the treated layer.
