The present invention relates to a tower collector used for forestry mechanization, and more particularly, it is easy to carry out the work of collecting logs using an excavator that is widely used for general engineering and forest engineering. The present invention relates to a tower collector using an excavator that is simple to hypothesize and easy to disseminate, thereby improving efficiency and economic efficiency of thinning timber production and greatly improving forestry productivity.

In general, the forest industry faces many difficulties due to poor forest resources, weak forest management base, high external dependence, low forest investment, low economic feasibility, and low productivity. % And the average accumulation is 79㎥ / ha, and 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 labor shortages required by the market, and to dramatically increase productivity.

Forestry mechanization is an urgently needed project to avoid difficult and dangerous forestry labor, and it will be able to supply stable timber 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.

On the other hand, forestry machines used for forestry include seedling packing machines, afforestation and meatless machines, and forestry opening for civil engineering machines, logging materials, and hauling machines. Among these machines, seedling packing machines can utilize general agricultural machinery, and for opening forest roads. Civil engineering machines can use the existing civil engineering machinery excavators, graders, breakers, etc., so there is no big problem. However, since planting and carcass work and harvesting work are carried out in a rugged mountainous area, it is very difficult to mechanize them, and the work is classified into yarding, skidding and forwarding after vehicle loading. Such collection methods may vary depending on terrain slopes, road networks, surface obstructions, and forests. Therefore, the airborne collecting method is most efficient in mountainous areas.

In particular, harvesting work in a mountainous area is not only a very difficult work, but also a collecting machine is a machine for the movement of heavy materials called solid wood, so research and development is necessary considering the advantages. Large forestry machinery may cause damage to the forest land or residual soil due to in-forest input. Therefore, measures to minimize damage to forest land need to be thoroughly reviewed before the introduction of machinery.

In addition, minimizing damage to forest land can be minimized through the development and dissemination of machines with low ground pressure, among other machines that can reduce the road width of work paths by using small collection vehicles with small body sizes, or those that can drive the forest directly on slopes. You must find ways to do it. In particular, the work of the household lineage collector may be able to use the wire collection method in forest land where there is less forest damage than the tractor system such as a tractor and the steep slope or soil erosion is concerned.

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

Conventional tower collectors are high-priced models that are dedicated to tractor towing or truck-mounted types. Therefore, the necessity of tower collectors to reduce costs in manufacturing and purchasing, to increase efficiency and economics of thinning production, and to improve forestry productivity was very large.

Meanwhile, a wire collector using a small excavator has been developed, which uses a single-circuit circulation type or a high lead type winch using a single drum. Such a conventional wire collecting device is not a running skyline method, which is generally used for tower collectors, and has a small winch as a simple winch type collector. In addition, by using a small excavator, it is impossible to collect all the wood of large hardwood, and difficult to downwardly collect. In addition, the operation is a form using the hydraulic lever directly from the excavator driver's seat, which has a big impact on the safety and burden of work.

The present invention is to solve the conventional problems as described above, the purpose is to fit the steep slope terrain, easy to move the hypothesis, using a excavator that is widely used for forest civil engineering can be carried out at the same time to collect wood work To provide a tower collector using an excavator.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the drawings.

The tower collector 1 using the excavator according to the present invention is mounted on the excavator 5 so that the work of collecting wood W can be easily performed.

As shown in FIG. 1, the tower collector 1 using the excavator according to the present invention is mounted on the main body of the excavator 5 and wound around the wire ropes 14a and 14b of the holeback line and the main line, respectively. And second winch portions 10a and 10b. The position of the operation control valve box of the first and second winch parts 10a and 10b and the hydraulic control part 20 to be described later is arranged by utilizing a free space opposite the driver's seat of the excavator 5.

As shown in FIG. 2, the first and second winch parts 10a and 10b are wound around the first and second drums 12a to which the wire ropes 14a and 14b of the holeback line and the main line are respectively wound. 12b, the first and second drums 12a and 12b are driven by hydraulic winch motors 22a and 22b of the hydraulic control unit 20 described later in connection with FIG. Reverse rotation is possible.

And the boom bar 5a of the excavator 5 is equipped with an encoder 42 of the rope speed detection unit 40 to be described later to serve as a direction change and support of the wire ropes 14a and 14b. Doing. The first and second winch portions 10a and 10b are installed by turning in the direction of the boom stand so as to correct the direction of the wire ropes 14a and 14b directed to the boom stand 5a. That is, since the direction of the wire ropes 14a and 14b is not correct by the distance between the boom stand 5a of the first and second winch parts 10a and 10b, the first and second winch The parts 10a and 10b are installed by turning the direction slightly in the direction of the boom stand 5a. The boom stand 5a acts as a tower by raising the boom stand 5a. Tower-yarder work is possible.

As the main design specifications of the first and second winch sections 10a and 10b, the diameters and widths of the drums 12a and 12b, the diameters and the winding amounts of the wire ropes 14a and 14b, ie, the collection distance Determined by calculation.

In addition, the tower collector 1 using the excavator according to the present invention includes hydraulic winch motors 22a and 22b for rotating the drums 12a and 12b of the first and second winch parts 10a and 10b. It has a hydraulic control part 20 to hydraulically operate.

As shown in FIG. 3, the hydraulic controller 20 adjusts the moving speeds of the holeback line and the mainline wire ropes 14a and 14b through an encoder 42 of the rope speed detector 40. As shown in FIG. 4, the wire ropes 14a and 14b of the holeback line and the main line are adjusted by adjusting the opening amount of the proportional control valves 24a and 24b provided therein. The windings adjust the speeds of the drums 12a and 12b of the first and second winch parts 10a and 10b differently so that the moving speeds of the wire ropes 14a and 14b are synchronized and the interlock is made.

The hydraulic control unit 20 may automatically or manually drive the first and second winch units 10a and 10b. In addition, the hydraulic control unit 20 performs an interlock function through the proportional control valves 24a and 24b, which detects the feed rate of the wire ropes 14a and 14b by the encoder 42. This value is to be recognized by the controller 28 of the hydraulic control unit 20, and then converted to a current corresponding to the set speed to control the opening of the hydraulic control valve.

The proportional control valves 24a and 24b are main control valves for changing direction and adjust the flow rate in accordance with an electrical signal from the encoder 42, and the winch motors 22a and 22b rotate. By controlling the role of maintaining the unwinding speed and the winding speed of the drum 12a (12b).

Since this hydraulic control technique uses proportional control valves 24a and 24b based on the movement speed of the holeback line and the mainline wire ropes 14a and 14b, The speeds of the drums 12a and 12b of the first and second winch sections 10a and 10b wound on the wire ropes 14a and 14b are adjusted differently so that the movement speeds of the wire ropes 14a and 14b are synchronized. Accordingly, the holeback lines and the mainline wire ropes 14a and 14b have the same moving speed and are always wound and moved to the drum 12a and 12b stably without sagging or tangling due to the speed difference. .

The set speeds of the wire ropes 14a and 14b refer to target transfer speeds of the holeback line and the main line, and the controller 28 provided in the hydraulic control unit 20 is the proportional control valves 24a and 24b. By controlling the passing flow rate of the wire rope 14a (14b) of the holeback line and the main line is repeatedly operated continuously to reach the set speed. Therefore, the wire ropes 14a and 14b of the two holeback lines and the main line have the same feed speed as possible, so that the feed speed of the conveyer section 50 in which the log wood is suspended is the same, and can run without sagging and pulling. It will induce and enable top-down and top-down aggregation.

In addition, the tower collector 1 using the excavator according to the present invention is mounted on the boom stand 5a of the excavator 5, and the holeback line and the main line of the first and second winch parts 10a and 10b. A rope speed detector 40 detects a moving speed of the wire ropes 14a and 14b and outputs an electrical signal.

The rope speed detection unit 40 is mounted to the boom stand 5a of the excavator 5, as shown in FIGS. 5 and 6, and the holeback of the first and second winch parts 10a and 10b. A plurality of encoders 42 including a plurality of pulleys 45 to rotate in accordance with the movement of the line and the main line wire ropes (14a, 14b), and outputs an electrical signal by detecting the rotational speed of the pulleys (45) It includes a structure.

The encoder 42 of the rope speed detection unit 40 detects a feed speed of the wire ropes 14a and 14b of the main line and sends this value to the hydraulic control unit 20. Two encoders 42 and a pulley 45 are mounted, respectively, and detect the speeds of the wire ropes 14a and 14b of the holeback line and the main line, respectively, and support the wire ropes 14a and 14b during the collecting operation. Because it plays a role, it must be very resistant to friction, traction, and tension. In addition, since the speed of the wire ropes 14a and 14b is sensed, if the speed response is not properly performed due to the sliding of the pulley 45 and the wire ropes 14a and 14b, the interlock function is not exhibited smoothly. Attention is drawn to the size of (45) and the positioning of the boom stand (5a) of the excavator (5).

In addition, since the kink phenomenon of the wire ropes 14a and 14b may occur due to the support by the traction force and the tensile force of the wire ropes 14a and 14b, the size (diameter) of the pulley 45 is appropriately adjusted. It should be calculated and designed to withstand loads of various moments of force. Therefore, the rope speed detection unit 40 is designed in consideration of such a load and frictional force, slippage, kink phenomenon, etc. of the wire ropes 14a and 14b, and especially the cutting or breaking of the wire ropes 14a and 14b and deepening them. In order to prevent the related kink phenomenon, it is preferable that the diameter of the pulley 45 is usually 20 times the diameter of the wire ropes 14a and 14b. Therefore, when the diameter of the applied wire rope 14a, 14b is 9mm, the diameter of the pulley 45 should be at least 180mm, so the diameter of the pulley is 190mm.

In addition, the rope speed detection unit 40 is connected to the encoder 42 and the pulley 45 in series so as not to lose the speed detection of the wire rope 14a, 14b as much as possible.

And the tower collector 1 using an excavator according to the present invention includes a conveyer unit 50 forming a wood (W) while moving on the wire rope (14a, 14b).

In addition, the conveyer unit 50 is the end of the wire rope 14a of the hole back line is fixed to one side of the frame 52, the wire rope 14b of the main line is fixed to the solid wood (W) (W) It is the structure that makes up the house. Such a conveyer unit 50 is a structure suitable for this when the tower collector 1 of the present invention applies the running skyline cutting method by adopting the interlock function.

The conveyer section 50 is connected to the wire ropes 14a and 14b of the main line by the load of the log wood W and the load of the conveyer section 50 itself during the work of collecting the log wood. Since the impact and the load are applied, the kink and breakage of the wire ropes 14a and 14b may occur due to the impact and the load, so the size (diameter) of the carrier pulleys 54a and 54b should be calculated. Accordingly, the diameters of the pulleys 54a and 54b are generally changed to the wire ropes 14a in order to prevent a kink phenomenon that is closely related to the cutting or breaking of the wire ropes 14a and 14b, similar to the pulleys 45 of the encoder 42. It is preferable to design it as 20 times the diameter of 14b).

In addition, a structure used in the running skyline cutting method is preferable so that the holeback line and the wire ropes 14a and 14b of the main line are not entangled with each other.
