(54) DEVICE FOR UNLOADING OF LOGS FROM WATER TO. SORTING CONVEYOR

I

The invention relates to devices for unloading logs from water to a sorting conveyor after cutting logs into assortments and can be used in the timber and woodworking industry in semi-automatic cutting and sorting lines for sawmill raids and lumberyards.

A device for unloading logs from water to a sorting conveyor is known, which includes a hydraulic flow with a device for transversely moving logs 1.

A disadvantage of the known device is the presence of manual labor and low productivity when unloading logs from water at high speeds of the water flow in the flow trap.

The purpose of the invention is the elimination of manual labor and the increase in productivity when unloading logs from water at high speeds of water flow in the hydraulic flow.

This goal is achieved by the fact that the hydraulic flow is staggered, and the device for lateral movement of the logs is installed in the tray's level at the bottom of the upper hydraulic flow stage and performed with driven screw rollers with an emphasis.

FIG. 1 shows a general view of the device, side view; in fig. 2 - then

10, plan view; in fig. I - section A-A in FIG. 2-.

The device for unloading logs from the water to the sorting conveyor consists of a hydraulic flow

IS from the upper cascade 1 and lower cascade 2. Above the lower cascade 2, the drive screw rollers 3 and the stop 4 are mounted to the bottom of the upper cascade and at the bottom of the upper cascade 1 so that

The flow of the hydrotreater 20, the pad from the upper cascade 1 to the lower cascade 2, washes the first screw rollers, and the latter are located above the water.

Next to the lower cascade 2, opposite the screw rollers 3, a accumulator-gel disconnector 5 is installed, made in the form of a tray with cross-feed chain conveyors.

Near the storage uncoupler 5 mounted sorting conveyor 6 with storage pockets 7,

The device works as follows.

The logs 8 flow through the upper cascade .1 and enter the driving screw, rollers 3. The water flow and the rotating screw rollers 3 of the log 8 are pressed against the stop 4 and the rotating screw rollers 3 are dropped into the drive-disconnector 5.

Since the hydraulic current is cascaded, the water flow, spilling through the spaces between the rollers 3, goes through the lower cascade 2 to the drain, leaving the logs on the rollers 3.

Then the logs 8 from the storage bin 5 are delivered one by one to the longitudinal sorting conveyor 6 and dropped into the storage pockets 7.

Such a design of the proposed device for unloading logs from water to a sorting conveyor completely eliminates manual labor and ensures high productivity at unloading from water.
