Description

side walls of the container, and the edges of the knives 2 protrude above them. From above, the tank 1 equipped the hinged lid 5 attached to the drink with the help of hinges 4, on the inner surface of which the knives in the form of stiffeners 6 are reinforced. In the lower part of the side walls of the vessel there are openings for removing bark and other waste products from timber from it. On the outer surface of the tank steak tanks, the support baidges 7 are attached, contacting with the supporting rollers 8 mounted on the foundation, and the gear ring 9, which is in gear with the gear 10 of the reverse drive (on the heel, not shown). A metal lobe 11 is fastened in the upper part of the support band, and a non-contact sensor 12 is mounted under the bandage, mounted on a fixed support 13 and connected to the control circuit (not shown) by a tank turning drive.

The proposed device follows the following AND: M way.

Timber to be debarked is delivered to the tank with 1 bag (long) or in bulk (wood, bough, tops) from the top with the lid open 5. Then the drive is adjusted in one of three possible modes of capacity movement: a) reciprocating (swinging) motion; b) rotational motion; c) combined movement - alternation of rotational movement with reciprocating rotational movement. In the first mode, timber processing can be carried out both with the lid open and with the lid closed, and in the second and third mode, with the lid closed and locked.

According to the first mode, it is advisable to handle wood, bough and tops, and sometimes the second mode should be used for better processing. In the third mode, the processing of longness is more efficient.

In the course of the rolling movement of the container, as a result of the interaction of the force of gravity, inertia and friction of the logs against each other and against the walls of the container with the knives 2 and 3 fixed on them, the bark separates. In this case, the wood is first contacted with short straight knives 2, which cut the bark randomly. Breaking off the knives 2, the logs fall on the more deeply located continuous screw knives 3, which cut the bark evenly along the entire length of the log. In addition, the screw knives are crushed into small pieces separated by short knives with long pieces of bark. Crushed on the bark, along with other waste (rot, branch residues, etc.) is removed from

containers in the process of processing timber through the holes a.

To unload the processed logs, the drive is tuned to the second mode and the capacity 1 is turned around the axis by 180 ° with the cover 5 down. As soon as the petal 11 enters the groove of the sensor 12, the latter actuates and switches on the relay, which by its contacts turns off the drive electric motor or the coupling

clutch The container stops, the lid opens (if it has been closed) and the logs are poured onto the conveyor belt, which carries them away from the area where the container is located. After the unloading is completed, the relay contacts are shunted in a known manner, the drive motor or clutch is turned on and the capacitance returns to its original position. The timber processing cycle is then repeated.
