Description

The invention relates to forestry machinery, in particular to tools for the preparation of the soil for planting and sowing of forest crops on undistorted logging2

kah with big clutter. The purpose of the invention is to improve the quality of the process and increase technical reliability. The device contains a frame 1. beam 2, undercut working body, made in the form of a two-tail plow body with horizontally positioned upper trimmed guides 5. The pickup width of the plow body is greater than the gripping width of milling drums 8. The upper trim of guides 5 is below the upper points of the circle described by the working elements of milling drums 8. When you move the tool, the cutting knife 3 cuts the soil vertically, and the trimming elements 9 cut the soil layer with woody inclusions. The cut layer moves along the guides 5, falls on the milling drums 8, which are intensively crumbled. 2 Il.

The invention relates to forestry machinery, and in particular to tools

to prepare the soil for planting and sowing

forest crops in the conditions of uncorrupted cuttings and with great clutter.

The aim of the invention is to improve the quality of the process and increase technical reliability.

FIG. 1 shows a tillage tool, side view; in fig. 2 - the same, top view.

Tillage tool contains a frame 1 with a longitudinal beam 2, on which is mounted a cutting knife 3, a wedge 4, made in the form of a two-dump plow body with horizontal upper edges of the guides 5, a gear 6 connected to the cardan shaft 7.

On the protruding axes of the gearbox 6 milling drums 8 are installed, the processing width of the soil strip of which is less than the width of the plow body. Bottom guides 5 are provided with an undercut working element 9. The upper edges of the guides 5 are located below a horizontal tangent drawn to the upper point of the circle described by the working elements of the milling drums 8.

Tillage tool works as follows.

When moving the unit along the uncorrupted cutting area, the cutting knife 3 cuts the soil with woody inclusions in the vertical plane. Wedge 4 partially spreads the logging residues and soil to the side of the center of the cutting knife 3. Undercut working elements 9 cut the soil in a horizontal plane, and raise the cut layer of soil at an angle to the direction of movement of the implement. With further movement of the layer of soil with wood inclusions, moving along the guides, enters the milling drums 8, rotating against the movement of the unit. Installation of work items 9 and guides 5 at an angle of attack to the direction of movement allows a portion of cutting residues to be shifted to the side of the passage of the unit and not to fall on the milling drums 8.

At the same time, a horizontal slice of the guides 5 ensures a uniform supply of soil and cutting residues over the entire width of the milling drums 8 and uniform crumbling of the soil. The location of the upper edge of the working elements of the milling drums 8 above the upper edges of the guides 5 provides effective crumbling of the soil layer, and the location of the upper edges of the guides 5 above the axes of rotation of the milling drums 8 eliminates frontal impacts on them from logging residues and wood inclusions in the soil.

Claims (1)

Claim Tillage tool, including a frame, undercut working body and 25 located behind him milling drums with working elements, characterized in that, in order to improve the quality of the technological process and increase technical reliability, undercut the working body made in the form of a two-dump plunger body with horizontally positioned upper cuts, and the pickup width milling drums, and its upper edges are located below the horizontal tangent held 35 to the upper point of the circle described by the working elements of the milling drums, and above the horizontal axis of rotation of the drums, the frame is single-sided and located along the longitudinal axis of the implement.
