The invention relates to the timber and woodworking industry and can be used for the longitudinal division of timber, mainly slabs.

The purpose of the invention is to increase work efficiency.

On .fig. 1 shows a side view of the device; in fig. 2 shows section A-A in FIG. one.

The device for longitudinal division of timber contains a splitting working body 1 in the form of knife plates 2 mounted on a shaft, a base 3, a feed mechanism 4, a clamping mechanism with a drive 5. The clamping mechanism contains rollers 8 mounted on intersecting levers 6 and 7 of pinned toothed discs 9 and 10. The axis 11 of the rotation of the intersecting levers 6 and 7 by means of belt or chain drives 12, 13 and 14 is connected respectively with the drive 5 and the rollers 8. The free ends of the intersecting levers 6 and 7 are connected by springs 15 and provided with mounted in the arcuate guides 16 the slides 17 and limiters 18 of rotation. On the base 3 is installed separation knife 19.

A device for the longitudinal division of timber works as follows. Upon receipt of the slab on the base 3 of the feed mechanism 4, the drive 5 of the clamping mechanism is inserted, which, through the belt (chain) gear 12, the axis AND of rotation of the intersecting levers 6 and 7, and the belt (chain) gears 13 and 14, rotated pinned gears 9 and 10 rotate rollers 8. The latter, in the course of their rotation, are brought out onto the outer surface of the slab and move it to the working element 1, the knife plates 2 of which split the slab.

The moving arms b and 7 by the springs 15 are attracted to the turn stops 18, thus ensuring the constant contact of the rollers 8 with the surface of the slab, regardless of its shape. The arcuate guides 16 for the sliders 17 provide rigidity and reliable feed by the rollers 8 slabs to the blade plates 2. The blades of the blade plates 2 form an acute angle with the forming surface of the slabs, thereby preventing the splitting forces from moving the slabs in the feed direction.

A separating knife 19, whose thickness is less than the thickness of the knife blades 2, divides the slab into two parts, destroying the wood fibers that are not separated by plates.

The use of waste-free dividing by splitting and ensuring constant contact of the rollers with. The surface of the slab, regardless of its thickness, increases the efficiency of the device.

Claims (1)

Invention Formula five A device for the longitudinal division of timber, including a base on which a splitting tool is mounted, a timber supply mechanism and a clamping mechanism with a drive, characterized in that, in order to increase the working efficiency, the clamping mechanism is made in the form of rollers mounted on intersecting arms, kinematically connected to the drive through the axis of rotation of the intersecting levers, the free ends of which are provided with rotation limiters installed in the arcuate guides by sliders springs connected, thus splitting the working body is formed as a shaft mounted on the cutter plates. 5 & i / e.
