SU393968A1 - CUTTER WITH VERTICAL SHAFT ROTATION - Google Patents

Description

one

The present invention relates to the agricultural machinery industry, in particular to tools for cultivating soil, for example, between the streets of the vineyards, and pristyvolnyh stripes in gardens.

A milling cutter with a vertical shaft of rotation is known, with cutting working tools (knives) fixed on it by means of radial spits.

This milling cutter is intended for processing interstitial trees in gardens. Its disadvantage is that the knives in the work process are constantly in the soil and, having performed a rotational-translational motion, they cut the same area twice: in the front part of the circle described by the knives and in the back. This leads to increased crushing of the soil, its sputtering and increased power consumption.

The purpose of the invention is to reduce the atomization of the soil when the cutter operates with a vertical rotary shaft and reduces energy consumption.

For this, the cutter provided is equipped with a device for deepening cutting tools by turning them in one of the halves of the circle described by them, made in the form of a sleeve mounted on each of the spokes, having a lever moving along the copier mounted on the shaft housing, and the working parts are connected to the sleeves .

FIG. 1 - shows the proposed cutter, side view, section; pas figs. 2 - the same, view to

axonometry.

Cutting elements (sheath) / mounted on racks 2, welded to the pipes 3. The pipes together with the sleeves 4 can rotate on the spokes of the spokes 5. On the sleeve from the side of the shaft hub 6

7, the levers 8 are welded. When the shaft rotates, the levers 8 in the back half of the circle described by them are deflected by the roller 9 of the copier 10 and slide along the surface of the copier attached to the shaft housing.

The proposed cutter works as follows.

From the tractor's power take-off shaft through the cardan shaft, the bevel gear and the chain transfer of rotation is transmitted to the shaft 7. When the shaft rotates, the levers 8 rotate and slide under the copier when approaching the roller 9 of the copier 10 and the blades come out of the soil and pass above the surface land. Pass the back half described by them

circle above the soil, knives after the arms go out from under the copier, due to their own weight are lowered to the soil surface, and then under the influence of resistance to cutting (soil reaction) are deepened.

Thus, the cutting elements of the cutter
