The present invention relates to a wood tong saw used for forestry mechanization, and more specifically, it is mounted on an excavator widely used for general civil engineering and forest engineering, and can perform timber productivity and loading and unloading work at the same time, thereby greatly increasing forestry productivity. It relates to a wooden tong saw with an improved excavator to improve it.

In general, the forestry industry faces many difficulties due to poor forest resources, weak forest management base, high external dependence, low investment in forests, low economic feasibility and low productivity. With 61% and average accumulation of 79㎥ / ha, there is an urgent need for forestry projects for forests planted in Chishan greening.

In addition, forestry is a representative 3D industry, and it is difficult to secure forestry labor force due to the continuous reduction of agricultural labor force and aging population. Therefore, high labor burden and reduction of production cost should be addressed urgently. In addition, it will be more difficult to obtain quality labor in remote mountain areas, and it will be very difficult to carry out forest work dependent on manpower.

Meanwhile, timber prices have been stagnant in the forestry industry, but labor costs of manpower-oriented forest work are increasing rapidly. Moreover, timber consumption is expected to increase further in the future, so timber production and supply will increase significantly in order to meet the demand for wood. Therefore, in order to increase the self-sufficiency rate of timber, forestry mechanization is urgently needed as a way to execute more thorough forestry work such as thinning, to replace the production of high quality hardwoods and the labor shortage required by the market, and to dramatically increase productivity.

Forestry mechanization is an urgently needed business in the reality of avoiding difficult and dangerous forestry labor, and it will be able to supply stable wood by relieving higher labor wages. In particular, the most demanding work among forest operations, logging harvesting machines are used depending on the high-cost imports. Therefore, research and development of forestry machinery is needed to increase the efficiency of thin-wood harvesting production, improve the productivity of forest work, and reduce forestry labor force through mass production of wood collecting machinery, and to secure technical skills of forestry machinery.

In particular, harvesting work in the mountainous area is not only a very difficult work, but also because the collecting machine is a machine for the movement of heavy materials called solid wood, it is necessary to research and develop in consideration of the advantages. Large forestry machines may suffer from damage to the forest or residual soil due to in-forest input, so it is necessary to examine them thoroughly before minimizing the forest to minimize damage to forest land.

Currently, the medium-large sized forestry machine developed and distributed for the forestry machine has a problem that the efficiency of the machine input decreases due to its high price but low utilization throughout the year. In addition, since it is spreading mainly on small machines, it is difficult to increase breakthrough productivity. Therefore, it is urgent to develop forest machines suitable for reality.

Conventional wood tong saws are a device of the function of the single-sized excavator attachment forceps, there is no domestic equipment of the wood attachment forceps and saw function for excavator attachment. Therefore, in the forestry industry, there is a great need for a small log clipper that can reduce costs in production and purchase, increase efficiency and economic efficiency of thinning timber production, and improve forestry productivity.

On the other hand, as a small wooden clip saw, a conventional wooden clip saw mounted on an excavator has been developed. Such a conventional wood clip saw is a machine designed to allow the stacking operation by using the function of picking up the wood and the rotational force of the forceps, but can exhibit the function of the wood collector, but there are two cylinders for the function of the tongs It is not a form of hug, but a house is a structure that is less functional and efficient.

Therefore, the development of a high performance wooden clip saw is urgent in the industry.

The present invention is to solve the conventional problems as described above, the purpose of which is the wood grapple saw using an excavator that can perform a multi-functional wood processing work at the same time using an excavator that is widely used for general civil engineering and forest engineering In providing.

And another object of the present invention is to increase the utilization of the excavator spread on the forest site by using an excavator, to reduce the cost in the development, production and purchase of forestry machinery, increase the efficiency and economic efficiency of thinning timber production and improve forestry productivity To provide a wooden clip saw with an improved excavator to make it possible.

In addition, as shown in FIG. 7, the braking function of the solid wood W is mounted on the casing 32 to one side of the lower housing 26, so that the solid wood (W) is mounted by the jaw members 16a and 16b. In the state of holding W), the wood W can be cut by the rotation and vertical action of the chain saw 34. In such a case, the position of the chain saw 34 may be horizontally moved horizontally by the horizontal moving cylinder 31 so that the wood W cutting position can be arbitrarily adjusted.

And the wood cutting portion 30 is an oil tank (US) so as to supply a certain amount of oil for the protection, cooling and lubrication effect of the chain saw 34 when cutting the wood (W) by the high speed rotation of the chain saw 34 And oil lubrication function. The wood cutting portion 30 is preferably a total length of the chain saw 34 is 1255 mm, the chain oil supply tank 4 liters, the horizontal movement distance of the chain saw 34 for adjusting the cutting position of the wood (W) Has a stroke of 100 mm. And it is preferable to adjust the cutting speed so that the wood (W) is cut within 5 seconds on the basis of the diameter 30cm of the wood (W).

In addition, at the same time as the chain saw 34 rotates, the chain saw 34 moves downward by the movement of the saw turning cylinder 35, and the wood W is cut by the rotation downward movement of the chain saw 34. , The cutting is completed and at the same time the chain saw 34 returns.

Solid wood clip saw 1 using the excavator according to the present invention is effective to reconstruct the wood for thickened branches, such as pine or hardwoods, the trunk is not straight, using the wood collector (10). That is, the wood grapple saw (1) using an excavator according to the present invention can be stacked together with the wood work, as shown in Figure 10a, as shown in Figure 10b), tangled wood It can be conveniently stacked while standing on the ground, and as shown in Figure 10c), can be carried out by arranging the stacking to fit the length of the wood.

In this way, the present invention is the wood work and the wood work (W) stacking work by the wood collecting part 10 and the up and down work is a powerful power of the excavator (5) and a variety of work range and ability, the strong grip force of the wood collector 10 It can be used efficiently for all timbers, timbers, and timbers. The woodworking and stacking work by the wood collecting part 10 may be carried out after all the work is finished by the wood clip saw 1 using the excavator according to the present invention, or may be performed even during the work.

In other words, after finishing the work of collecting wood, reworking and stacking work can be more efficient. In addition, it is advantageous in terms of work efficiency to carry out woodwork and wood stacking at the same time, thereby increasing work efficiency.

And after carrying out both the reworking and stacking work using the wood collecting portion 10 of the wood tongs saw 1 using the excavator according to the present invention, if the loading and unloading work for transporting work by trucks, etc. It was proved advantageous to carry out loading and unloading and transportation work collectively after all the work in the target site of the collecting work was finished.
