Description

[0001] The present invention relates to a drum braking device for a timber collector,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a drum braking device for a garbage collector, and more particularly, to a drum braking device for a garbage collector, Drum braking device.

In general, the forestry sector faces many challenges, including poor forest resources, weak forest management infrastructure, high dependence on external sources, low investment in forestry, low economic efficiency and poor productivity.

In addition, since forestry is a typical 3D industry, it is difficult to secure the labor force of the forestry industry due to the decrease in agriculture and the aging of the agricultural labor force. Therefore, it is urgently necessary to solve the labor burden and the production cost. It will also be more difficult to obtain good quality labor in mountainous regions, and it will be very difficult to carry out forestry work that depends on manpower.

On the other hand, in the forestry industry, the price of wood is still stagnant, but in the case of forest work focusing on manpower, the share of labor costs in the production cost of wood is rapidly increasing.

Moreover, since the consumption of wood is expected to increase further in the future, the production and supply of wood chips will increase significantly in order to meet the demand for timber.

Therefore, in order to increase the self-sufficiency rate of wood in the future, mechanization of forestry is desperately needed as a method to carry out thinning operations such as thinning, to replace the shortage of required labor,

Mechanization of forestry is a business that is desperately needed in the reality of avoiding difficult and dangerous forestry labor, and it will be able to supply stable wood by solving higher labor costs.

Especially, most of the most difficult work in forestry is the reeling machine for reeling machine for reeling machine. Therefore, it is urgently necessary to research and develop forestry machinery to increase the efficiency of thinning production, to increase the productivity of forestry work, to replace the diminishing forestry labor force, and to secure the technology of forestry machinery.

On the other hand, the forestry machinery used for forestry is a plowing machine, a planting machine and a non-plowing machine, and a machine for laying ground machinery, a cutting machine and a lawnmower. Among these machines, the machine for plowing plant can utilize general agricultural machine, There is no big problem because the civil engineering machine can use excavator, grader, breaker, etc., which are existing civil engineering machines.

However, it is very difficult to mechanize the forestation and mowing work and logging work in the mountainous region. The work of mowing work includes yarding of public wire rope, skidding of the ground, and forwarding of the vehicle. , And the method of collecting work can be changed depending on the terrain inclination, the road network, the surface obstacle, and the ruins.

Therefore, aerial wire rope gathering method is most effective in mountainous areas like Korea.

Currently, most of the timber production work is made up of manpower-oriented work systems, and the labor productivity is only 1/10 of that of the forestry advanced countries. Because of this, labor burden of workers is high and accident rates such as safety accidents are very high Since the industrial accident insurance rate is the highest in the entire industry, it is necessary to increase labor productivity through mechanization of forestry and to reduce disaster rate.

In addition, the labor force of the agriculture and forestry industry is rapidly declining, and the securing of the labor force of the agriculture and forestry industry is serious. Especially, it is more severe in the forestry work where the level of mechanization is remarkably lower than that of agriculture.

In addition to industrialization and urbanization, the labor shortage of farming villages due to the concentration of population in cities is intensifying. Moreover, due to the avoidance of 3D occupation, the labor shortage of forestry is getting worse and it is necessary to mechanize the forest work and securing excellent functions .

Because the slope is steep in the mountainous region and the wood is heavy, it is dangerous and hard work for the collection and transportation work. Therefore, it is becoming more difficult to secure the forestry labor force due to the 3D phenomenon and the lack of functional manpower Has become a major obstacle to the activation of forestry in addition to shrinking the whole forest work.

In addition, in the present timber production process, most of the logging process is performed by the chain saws, and the heavy grabbing by the manpower and the wood grab with the small excavator.

Particularly, in the mountainous area where the steep slopes are mostly in the mountainous area, the work of building the trees is unreasonable, and the work of the heavy cargo stacking work by the excavator woodgrape is done, and the damage of the forests such as the collapse and the forest terrain are serious. Therefore, in the forest area, the slope is urgent and many obstacles are required, so towers and wire ropes that lift and pull down the joining tree are required. Also, the power of the towing force is required because the joining tree is heavy.

In this way, mechanization is urgent in the field of forestry. However, since the supply and introduction of forestry machinery is costly, it is necessary to take measures for economic and industrial cost of forestry machinery and activate forestry.

Currently, the necessity of forestry machinery has increased, and the supply of forestry machinery is increasing. However, due to the absence of forestry machinery that can be introduced into the country, equipment that is not suitable for mountainous terrain is introduced and used.

In addition, the typical harvesting system used in the harvesting is mainly used by logging operators. The system is used for making bees and chasers using chain saws, and for picking and harvesting by using woodgrap with excavator. This is a method of producing timber as a wood by using a truck for sowing (Young-Ung).

Therefore, it is a serious problem that the efficiency and the degradation of the mountainous area are serious due to the production of the timber production centering machine rather than the wire rope centering machine suitable for steep slopes. Therefore, the harvesting system of the timber using the tower rope- It is necessary in the system.

Taking this into account, a tower type collector has recently been disclosed which is coupled to a tractor in Patent Application No. 10-2007-0030149.

A tower type collector coupled to a conventional general tractor includes a main body having a connecting rod connected to a tractor to receive power from the tractor, a boom fixed at one end of the main body, And a skyline supported on one of the wire-supporting pulleys while the carrying member is installed. The skyline of the skyline is supported by a sheave of the wire- A skyline support portion on which a wire is wound; and a wire wound on the other of the wire support sheaves to be wound in a forward direction so as to rotate according to the power of the tractor transmitted through the connection rod to pull the transport member A take-up drum, and a tractor, which rotates according to the tractor power transmitted through the connecting rod, A return drum which is wound in a reverse direction and which is supported by another pulley of the wire supporting sheave in a reverse direction and a power source for driving the tractor which is transmitted through the connecting rod when the connection rod is connected to the tractor And a power transmission portion for supplying or cutting off the wind from the take-up drum and the return drum, respectively.

The power transmission unit may further include first and second drum brake levers for restricting rotation of the take-up drum and the return drum when the tractor transmits power between the take-up drum and the return drum by the first and second power transmission levers, .

However, as described above, the first and second drum brake levers provided on one side of the take-up drum are directly operated by the operator holding the drum brake lever by hand, And the braking operation is performed by the braking operation. Therefore, there is a possibility that the operator may be injured during the braking operation, so that the braking operation is exposed to the safety accident at all times and the braking of the take- There is a disadvantage that accurate braking can not be achieved.
