Description

(5) WORKING AUTHOR OF THE FORMWORDS PICKER

I

The invention relates to logging and forestry machines and can be used in the forest industry and forest management.

A known device for collecting logging waste, mounted on a self-propelled chassis and consisting of two main parts - a straight lever, hinged to a self-propelled chassis, and a curved tooth rigidly attached to the lever Gt by its upper end.

A known working body of the collector of logging wastes, containing a curvilinear tooth with a depth limiter for its depth, made in the form of a plate 12.

The disadvantages of these devices are a significant content of mineral impurities of the soil in the bundles of boughs formed by this device, so that at the same time with the collection of boughs, the teeth loosen

soil; a significant amount of resistance to loosening the soil by the tooth, since the formation of soil chips is carried out by the edge of the tooth tip.

The purpose of the invention is to reduce traction effort and soil content in the collected boughs.

The goal is achieved by the fact that the working body is provided with a wedge, which is located on the lower side of the plate and is offset towards the direction of movement of the picker relative to the end of the tooth.

In Fig. 1 shows the proposed working body; in fig. 2 - wedge; in fig. 3 is a view A in FIG.

Claims (2)

The working body contains a curved tooth 1, to the bottom plate of which, by means of, for example, a kerchief 2, a plate 3 is rigidly attached. The wedge k has an acute angle in the plan, a straight cutting angle and a rounded top. In the process of collecting branches, teeth 1, the front free part of plate 3 slides along the soil surface. Soil loosening, necessary to improve the promotion of natural reforestation S, is carried out by a wedge k located behind the lower end of the tooth. The soil pushed by the side edges of the wedge k onto the surface of the earth is located on the sides of the back side of the lower end of the tooth, excluding its contact with the branches. The front free part of the plate 3 eliminates the tooth's toothing 1. The need for a direct cutting angle of the wedge is explained by the presence in the soil of the root system of shrub vegetation. With an acute value of this angle, the roots may get into this angle and jam them between the plate and the wedge blade. With a blunt cutting angle, the conditions for the tooth to bypass the roots are facilitated, but this can cause the tooth to deepen. The sharp angle of the wedge in the plan and the straight in the profile are necessary to reduce the magnitude of the resistance to cutting of the soil, the rounded width of the wedge is 6 4 to exclude the cutting of the Wood during the bypass of the stumps. The present invention makes it possible to use the boughs collected by the device for collecting logging waste for industrial processing, and by reducing the resistance to cutting the soil to facilitate the operation mode of the self-propelled chassis, to increase its speed and productivity. Claim of the invention The working body of the logging waste picker, containing a curvilineated tooth with a depth gauge in the form of a plate, characterized in that, in order to reduce the pulling force and soil content in the boughs, it is provided with a wedge located on the lower side of the plate shifted towards the direction of movement of the picker relative to the end of the tooth.
