Abstract

The invention can be applied in low quality wood processing lines. The goal is to reduce energy consumption and increase reliability. The machine includes a thrust mechanism 2 and a splitting body comprising a horizontal knife 5, which is mounted on axis 4, and vertical disk knives 7 freely mounted on guide 6. When splitting, the churak advances mechanism 2 first on knife 5, which rotates on axis 4, the copier thereby the direction of the wood fibers. The disk knives 7 freely move along the guide 6, also copying the splitting line, copying excludes the cutting of the knives in the wood and their jamming. 3 il. a (l o: oo-j o ate (; o fig. 2

Description

one

The invention relates to forest industry and can be applied in low quality wood processing lines.

The purpose of the invention is to reduce energy consumption and increase reliability of operation.

Figure 1 shows the machine, a general view; in fig. 2 - splitting body; on (| u, 3 - the moment of splitting.

The machine comprises a frame 1 on which a thrust actuator is mounted in the form of a chain conveyor 2 with stops, an excavator 3, hinged on axis 4. A horizontal axis 4 is fixed perpendicular to the thrust direction of the timber.

Splitting organ 3 comprises a horizontal knife 5c fixed on the side walls of the guide. 6, vertical knives 7 in the form of discs, pressed by springs 8.

The machine works as follows

Churak 9, placed in a chain conveyor 2, is moved by abutment against splitting body 3 and slides over a horizontal knife 5.

As the knife 5 moves in, it copies the splinter line of the block, turning about axis 4, and eliminates jogging into the wood, thus reducing the splitting force and reducing the likelihood of blockage of the block 9.

The lower segment of the churak 9 is further split into pieces, thrust over the vertical circular knives 7, which turn over when the churak 9 is thrust. The circular knives 7 also copy the splitting line, moving along the horizontal guide 6, and do not slaughter the wood. The number of vertical knives determines the degree of grinding of the block 9.

The upper part of the block 9 remains on the horizontal knife 5 and either returns to re-splitting or is pushed further by the next block.

The wood located under the horizontal knife 5 is pushed out of the machine by the next block.

The use of a digging unit consisting of horizontal and vertical knives hinged on the machine frame, allows to get stabbed logs of limited size without significant splitting energy, since knives do not cut into the wood during the splitting process.

The use of a hinged horizontal knife eliminates the possible jamming of the block between the knife and the stop of the thrust mechanism when the latter is hit by the block. The stop passes under a churak, it is lifted together with the splitting unit, and there is no jamming and stoppages that reduce productivity.

Claims (2)

1. A wood splitting machine, including a mounted and mounted thrust mechanism and a splitting body with articulated horizontal and movable vertical knives, characterized in that, in order to reduce energy intensity and increase reliability, the hinge axis of the horizontal knife is set perpendicular to the thrust direction, and vertical knives mounted on a rail which is fixed on a horizontal knife parallel to the axis of the latter. 2. The machine is pop.1, it is distinct from the fact that the vertical knives are made in the form of discs, and their guide is in the form of an axis.
