Description

 ,,

The invention relates to the harvesting of the forest industry and forestry, in particular, to a device for separating greenery from the tops of trees, and can be used in the production of vitamin flour and wood chips.

Devices are known for separating wood greenery, c) 1 is a heat chamber with installed in them. rotayschritsim 6are1banom with teeth

and p |) 1st iodine ij.

The closest to the invention to the technical essence and the achieved result is a device for separating wood greenery from Kpomi trees, including feed organ, heat chambers and mounted inside them a foreign drum with working bodies on its inner surface L J.

The drawbacks of such devices are the low-intensity and incomplete separation of wood greens, leading to a decrease in the quality of separation and overall performance of the device. In these devices, the whole crown mass is processed and there is no working body capable of penetrating and acting on any needle located inside the crown layer or on the branches of the branches. Such hard-to-reach needles remain not separated on the crown, reduce the quality and productivity of the branch of wood and fall together with the wood into process chips, significantly degrading its quality.

The purpose of the invention is to increase productivity.

The goal is achieved by the fact that the device is provided with rings, and additional working bodies are located on the inner surface of the rings radially.

FIG. 1 shows schematically the described device for separating greenery from the tops of trees, side view; in fig. 2 is a transverse section A-A in FIG.

The device contains the feeder body 1, the heat chamber 2 and mounted inside them. drive drum 3 by the main working bodies 4. On the inner surface of the drum 3 there are additional working bodies 5 located on the inner surface of the rings b radial. The interpretative working bodies 5 can be made in the form of metal needle rods. Drum 3 mounted on track rollers

7 and rotates from the actuator 8. To receive the debris and the separated greens, the thermal chambers 2 have hoppers 9 and 10 respectively.

The operation of the described device is carried out as follows.

The crown of the trees supplying the body 1 is pushed through the heat chamber 2 into the drum 3 rotating from the drive

8 on skating rinks 7 and inclined towards the exit. In drum 3, the greens on the crown dries out (under the influence of the coolant supplied to the drum), and the bulk of the greenery is crumbling as a result of exposure to the main working bodies. Fallen from and finding work | At the available places, the greens under the action of the pressure of the next pack of crown come into interaction with additional working bodies 5 located

on the inner surface of the rings 6. These additional working bodies 5 penetrate to each unseparated greenery (needle, leaf) and intensively and completely clean it from the wood. The number of rings 6 is adjusted to ensure reliable and complete separation of all greens. Separated

The greens are poured into the receiving bin 10, and, free from the greens, the crown falls out of the open end of the drum and is recycled into process chips.

The establishment on the inner surface of the drum 3 additional working bodies 5 located on the inner surface of the rings 6 radially, facilitates penetration

and the impact of additional working bodies 5 for each inaccessible greens. As a result, device performance is improved.
