Description

Cutting into firewood of long-length firewood supplied by logging organizations is usually carried out at the place of consumption. The sawing of wood is carried out on circular sawing machines, after which each log is manually laid on a mechanical splinter for splitting. Thus, the known machines for mechanized cutting of lengthy firewood are inefficient and require a large amount of manual labor.

The proposed wood-staving machine does not have these disadvantages. The essence of the invention is that the loading chutes of the machine are equipped with limit switches, which automatically actuate the hydraulic actuators of the axes mounted under the conveyors when the blockheads enter.

FIG. 1 shows a kinematic diagram of a wood saw; in fig. 2 - the proposed machine, side view.

From the electric motor 1 through the belt drives 2, the rotation is transmitted to the disk saws 3 to 4, as well as to the oil pump 5. From the other electric motor 6 through the gearbox 7 and the sprocket 8, the rotation is transmitted to the shaft 9, on which the drive sprockets of the 10 pulls 11 are attached.

The long logs are laid on the receiving table 12, then hooks 13 mounted on the traction chains //, are fed to the circular saws 3 and 4. When the log moves, the third part is sawn off by the saw 4 and comes along an inclined plane 14 to the splinter blade 15. Then the rest of the log goes on sawing with saw 3, which cuts it into two parts. One part of the inclined plane 16 falls on the blade of the splinter 17, and the other - on the inclined plane 18 - onto the blade of the splinter 19. Thus, sawing and splitting of each log into parts occurs.

The hydraulic jibs are automatically operated by two-way hydraulic sliders, switched by electromagnets or by mechanical cam locking, attached to the corresponding chains.

When using the proposed machine, 85-90,% of the total amount of firewood is well chopped, and this provides the possibility of industrial use of the machine.

Subject invention

Chisel and wheel saw with the use of inclined chain feed conveyors, circular saws and mechanical sticks, characterized in that to increase the productivity of labor under the conveyors several axles with hydraulic actuators and loading chutes equipped with end switches, automatically driving the hydraulic actuator when entering the churak are mounted .
