Description

The purpose of the invention is to increase the productivity, efficiency and quality of the debarking process.

The device for group debarking of timber contains a drive drum with working bodies on the inner surface and loading and unloading mechanisms; it is equipped with a mechanism for notching bark in the form of spring-loaded disk knives mounted on levers in the loading tray. The circular knives that form the ring pre-process the timber by cutting only the bark over their entire side surface. The timber in the process of loading into the drum passes through the ring of circular knives in the loading chute, which provides for incision of the bark. FIG. T shows a device for group debarking of timber, side view; in fig. 2 is a section A-A in FIG. 1; in fig. 3 moment of passing through the ring-knives ring

The device for group debarking of timber contains a driving debarking drum 2 mounted on the base 1, mechanisms for unloading 3 and zafuzki 4. Inside the loading mechanism in the form of a tray there is a round window 5 for centering the forest material. In the lower part of the window 5 there are spring-loaded sectors 6. In the tray there are Circular knives 7 fixed with the help of levers 8 and springs 9 and forming a ring 10 inside which the timber passes. Timber is fed into the loading mechanism by a longitudinal conveyor 11. The drum 2 has retaining rings 12, by means of which it rests on the rollers 13. The rotary movement of the drum is driven by a drive (not shown) with a gear 14, mounted on the drum 2.

The device works as follows.

Round timber 15 through the conveyor 11 is fed into the tray of the loading mechanism 4. The timber enters the round window 5 and acts on the spring-loaded

sectors 6, which deviate center the timber relative to the ring 10 of the circular knives 7. Under the action of inertial forces and the own weight of the timber, it takes up a vertical depletion and falls. At the same time, it passes inside a ring of circular knives that incise the bark on the lateral surface of the timber. The springs 9 allow the blades to deflect

when meeting with irregularities or defects in the form of timber, as well as during the passage of timber of various diameters. After pretreatment of the timber during the passage of the ring

circular knives are fed into the debarking drum, where the main treatment is carried out - group debarking by mutual collision, friction of timber between each other and knives, located

on the inside of the drum. Gradually, the timber inside the drum moves to the discharge mechanism 3, made in the form of a truncated cone. Pretreatment of each

by cutting the bark, the coefficient of friction of the debarked timber during the main treatment is increased, the debarking time is significantly reduced, wood loss is reduced, and the productivity of the debarking drum is improved. In addition, the device allows to provide high performance and high-quality processing of round losmaterials, regardless of their

condition (frozen, dry or wet wood) and time of year.

Claims (1)

The claims of the group debarking of timber products, mounted on Based on the drive drum with working bodies on the inner surface and loading and unloading mechanisms, characterized in that, in order to increase the productivity, efficiency and quality of the debarking process, it is equipped with a mechanism for cutting the bark in the form of Iodoproplated disk knives mounted on the levers in the loading tray.
