(54) MACHINE FOR PREPARATION OF LANDING PLAYS

I

FIELD OF THE INVENTION The invention relates to agricultural machinery, in particular, to machines used primarily for carrying out silvicultural works on slopes.

Machines for preparing landing pads are known, including a casing mounted on a frame with radial and side knives fixed on it, a vertical stand with a hole-forming working body and a drive mechanism 1 and 2 placed in the casing cavity.

A disadvantage of the known machines is that when working on humid soil and in strongly stressed areas, sticking and clogging of the internal cavity of the casing, especially in its upper part, with soil and plant residues occur. This significantly reduces the productivity of the machines, as the cleaning of the housing requires stopping the unit. In addition, the quality of the prepared sites decreases due to poor loosening and the uneven movement of soil around the site. With a strong sticking of the casing by the soil, due to inertial forces, the beating of the working body and the gun as a whole increases, which reduces its operational reliability.

The purpose of the invention is to increase the productivity and quality of the training of landing sites.

This goal is achieved by the fact that the maschine for the preparation of the landing pads is additionally equipped with plate-shaped rippers, which are mounted along a helical line on the vertical rack of the well-forming working body.

When this rippers are located in the upper part of the cavity of the casing.

FIG. 1 shows schematically the proposed machine, side view; in fig. 2 is a diagram of fastening of rippers on a stand, section A-A in FIG. one.

The machine for preparing landing pads consists of frame 1, gear 2, casing 3, vertical pillar 4, in the lower part of which there is a hole-forming working body 5, and in the upper part, in the internal cavity of casing 3, rippers 6, made in the form of plates and fastened along a helix.

The kinematics of the drive of the working bodies are designed in such a way that the casing 3 rotates in the opposite direction relative to the vertical support 4, on which the hole-forming working body 5 and the rippers 6 are fixed.

Machine for nodgotovka landing sites works as follows.

The unit drives on a slope, and the operator turns on the drive. The gearbox 2 mounted on the frame 1 provides rotation of the casing 3 in the opposite direction relative to the vertical pillar 4, on which the hole-forming working body 5 and rippers 6 are mounted. As the frame 1 is lowered, the hole-forming working body 5 penetrates the ground and prepares the landing weave in the canvas, and the casing 3 provides cutting and transportation of soil from the uphill side of the slope to the bulk part, thereby forming a platform.

At the time of cutting the ground with the blades of the casing 3, it is intensively raised into the upper part of the casing. At this moment, the rippers 6, installed in the upper part of the inner cavity of the casing 3 and rotating in the opposite direction relative to the casing 3, reflect the ground downwards and additionally grind it. Installing the rippers at an angle to the plane and along the helical line of rotation provides better reflectivity and eliminates clogging of both the rippers themselves and the upper part of the casing 3 with soil and plant residues.

Upon reaching the required depth of the site, the operator raises the machine to the transport position and moves to the next place of work. Making the machine mounted on a vertical stand 4 above the well-forming working body 5 of the reflector-rippers 6, which have opposite rotation relative to the casing 3, improves the machine's performance and the quality of the prepared pads, eliminating the time previously spent on cleaning the casing from soil and plant residues.
