Description

one

The device can be used on raids of timber processing and sawmill enterprises.

A device for grinding beams of round timber, containing a floating base of two rigidly connected beams of pontoons, between which is located the grinding chamber, and the mechanism of single-piece supply of timber to the discharge conveyor 1.

The known device does not provide grind bunches of round timber of various lengths.

In order to ensure the grinding of beams of round timber of various lengths in the proposed device, the grinding chamber is made with semicircular levers attached to the pontoons, pivoted by means of a drive in a vertical plane.

FIG. 1 shows the proposed device in the plan; in fig. 2 - the same device, in cross-section; in fig. Figure 3 shows the location of the clamping levers before the beam is pulled up at the time of the end of the grinding.

The device contains two pontoons 1 interconnected by transverse beams 2 and guides 3 along which the threads of the lamellar-sleeve chains 4, which are equipped with hooks 5 and driven 6, move underwater swing arms 7 hinged to one of the pontoons drive 9 receive oscillatory motion in the vertical plane. The pressing of the swing arms to the bundle of round timber 10 is controlled by the limit torque coupling 11 and the brake 12. The device operates as follows.

The device is mounted at the discharge conveyor 13. The levers 1 by the actuator 9 are lowered to the lower position. A round timber bundle 10 is pushed onto the levers and pressed against the pontoon 1 with a certain force. The magnitude of the pressing force of the beam is controlled by the coupling 11 of the limiting moment. When you turn on the drive 6, the chain 4 with the hooks 5 capture preloaded round timber. As unloading round

Timber levers 7 are raised to the top position by a drive 9. In case of exceeding the pressing force of round timber levers 7, the torque limit clutch is disengaged. At this time, the gross line

the drive 9 is braked by the brake 12. The clutch of the torque limit is turned on when the pressing force is reduced to a predetermined value. The extreme lower and upper positions of the levers 7 are controlled by limit switches. After unloading the round timber, the levers 7 are lowered to the lower position, the cycle is repeated.

The use of the proposed device makes it possible to completely mechanize the process of unloading round timber of any length from the water to the shore, with an increase in productivity of 1.5-1.8 times and ensuring the safety of workers, reducing the power consumption during its operation. The metal consumption and labor costs for the manufacture of the device are cut, doubled.
