RU2484953C1 - Method of chopping short timber by rotary chopping blade - Google Patents

Abstract

FIELD: process engineering.

SUBSTANCE: invention relates to woodwork and may be used in harvest of wood stock for production of fuel or process kindling and firewood for boiler houses. Chopping blade penetrating into timber fixed at opposite end revolves about its axis and that of timber. Chopping blade splits timber by breaking the bonds between timber fibers.

EFFECT: expanded operating performances, higher efficiency.

Description

The invention relates to the forest industry and can be used in the procurement of wood raw materials for the production of fuel or wood chips, as well as firewood for boiler rooms.

A known method of splitting wood with a gripping-cutting organ, in which the transverse cutting of the upper half of the log and its splitting is carried out simultaneously by introducing the ends of the jaws of the gripping-cutting organ into the side surface of the log and their closing (Patent No. 94018125 RF, IPC6 B27L 7/00. Cutting method wood grasping / cutting body./ Hyuvenen K.N., Shegelman I.R., Golubev G.A. No. 94018125/15; Declaration 05.17.94;

The disadvantages of this method are significant energy costs and the complexity of the implementation.

The closest in technical essence is a method of splitting wood, involving the introduction of a wedge in the direction of the wood fibers (Schelgunov, Yu.V. Technology and equipment of timber enterprises. / Yu.V. Shelgunov, G.M. Kutukov, N.I. Lebedev. - M .: MGUL, 2002 .-- 589 s, pp. 51-55, Fig. 2.13).

The disadvantage of this method of splitting are the high energy costs in the production process.

The technical result consists in expanding technological capabilities and increasing the efficiency of obtaining wood raw materials by splitting.

The technical result is achieved by the fact that, in contrast to the rectilinear movement of the splitting element, the splitting organ, after being introduced into the timber fixed on the other end, rotates relative to the combined own axis and the axis of the split timber, splits it by breaking the bonds between the wood fibers.

The proposed method allows for the splitting of short timber with less energy.

In the patent and scientific and technical literature, we did not find such a method for splitting short timber.

Figure 1 shows the trajectory of the splitting organ and the location of the timber, and figure 2 is a top view.

The proposed method allows you to motionlessly fix the short timber 1 from one end and penetrate into the wood from the opposite end of the splitting body 2, which then makes a rotational movement and splits the timber.

According to the proposed method, the splitting of short timber is as follows.

Short timber 1 is installed and fixed, so that one end could not make a rotational movement. On the opposite side, a splitting organ 2 is buried in the wood, which then rotates and splits the timber 1. The cycle is repeated until all the timber has been processed.

Using this method will improve the economic and technological efficiency of obtaining wood raw materials by splitting.

Claims (1)

A method of splitting short timber, involving the introduction of a splitting organ into the wood in the direction of the fibers, characterized in that the splitting organ, after being inserted into the timber, fixedly mounted at the other end, rotates relative to its own axis and the axis of the split wood, coinciding, breaking it by breaking the links between wood fibers.
