The present invention relates to a reclamation cutting device for tree waste, which is to separate the wood waste into coarse aggregates, wood by-products and soil powder, etc., and then cut and recycle wood by-products in order to effectively reproduce wood that was dug up for development. will be.

Generally, wood waste is wood (wood, plywood, etc.) included in the waste at the construction site, or wood, tree roots, etc. generated by road construction, wood (wood pallet, wood wire roll, etc.). Collectively speaking.

Conventionally, forest wastes are not systematically managed at all, and only a part of the generated wastes are being processed by the consignment processing company that has been reported.In addition, the forest wastes are stored in large quantities throughout the site for a long time, far exceeding 90 days, which is the current storage waste discharge standard. There was a problem of neglect.

As long as the wood waste is left unattended for a long time, the value of recycling due to the corrosion of wood is not only greatly reduced, but also the collection and transportation becomes more difficult and eventually landfilled. When a large amount of wood waste is buried at the construction site, As a result of the formation of spaces due to corruption, problems such as soil leakage as well as the possibility of collapse due to torrential rains occurred.In addition, even if wood wastes are stored in temporary storage, wood wastes cannot be recycled after mixing for a long time, and thus environmental pollution There was also a problem that provides a cause.

Accordingly, conventionally, a crushing device that is capable of quickly crushing a large amount of wood waste and recycling it in the form of wood chips or sawdust has been released and used. The crushing device is classified into a high speed rotor type and a low speed shredder type.

The high speed rotor type is a type that puts waste wood into the screen net and rotates the rotor equipped with the cutter at high speed to crush finely. In order to impact the crushed object, the rotation speed of the rotor should be maintained at 600 rpm or more. Therefore, the conventional high speed rotor type shredding device is designed to be 600 ~ 1800rpm.

The low-speed shredder type is a type in which a plurality of disks are interlocked with each other on two rotating shafts provided side by side, and the waste wood introduced between the rotating shafts is torn by a cutter formed on each disk and finely crushed. At this time, if the number of rotation of the disk is high, not only waste wood does not enter between the disk, but also enters the side of the disk is rotated in close contact with the engine to cause an overload of the engine. Therefore, the conventional low speed shredder shredding device is designed to be 5rpm or less.

In order to solve this problem, the wood waste sorting device of Korean Patent No. 2005-0074164 filed is as follows.

The cutting blade is formed in the shape of a hook to cut wood by-products and sawdust. The spacing of the cutting edges is dense, eradicating all re-nematodes in the pine.

Sawdust cut at the cutting portion is discharged through a conventional conveying device. Conventional conveying devices are not shown as conveyor types. The heating unit is a conventional heating device capable of controlling the temperature, and a detailed description thereof will be omitted.

Looking at the action of the wood cutting waste recycling apparatus according to the present invention made as described above are as follows.

Wood waste is injected into the hopper 10. Here, wood waste is wood waste that is mixed with remaining twigs, roots, coarse aggregates, and soil, except for the stem which is the raw material of pulp after the wood has been felled due to development, etc., and is crushed by wood grinder (drum grinder). Includes wood by-products, such as chopped wood twigs or roots, that have been torn into pieces. Wood waste is introduced into the hopper 10 to sort and reclaim soil from such wood waste.

Wood by-products and coarse aggregates and soil powders are sorted according to the particle size by the rotation of the rotating part, and wood by-products and coarse aggregates and soil powders are discharged separately. As the first drive motor rotates, the rotary blade 23a and the support 24 rotate together to rotate and transport the wood by-product and the coarse aggregate toward the aggregate discharge port.

At the same time, shake off the soil from wood by-products and coarse aggregates. The pulverized soil powder is removed through the soil discharge hole 21 while the wood by-product is rotated and transported. As the second drive motor rotates, the discharge screw rotates and discharges the soil selected in the second stage of the dispensing body by rotating the soil to the soil discharge port of the soil discharge pipe.

At this time, if the wood by-products and coarse aggregates are not smoothly discharged from the inside of the dispensing body 1 stage, the by-products and coarse aggregates can be smoothly discharged by tilting the dispensing body toward the aggregate discharge outlet centered on the inclination control. In addition, even when the soil powder is not smoothly discharged from the inside of the dispensing body 2, the soil can be smoothly discharged by tilting the dispensing body toward the soil discharge outlet.

Wood by-products and coarse aggregates discharged from the aggregate outlet fall into the aggregate discharge plate, while the coarse aggregate falls to the lower portion of the aggregate discharge plate by its own weight. Wood by-products fall off the aggregate discharge plate and are blown off by a blower to a certain distance. The loaded wood by-products are transferred to the next unit by conveyor belts.

Wood by-products moved by the conveyor belt is introduced into the inlet through the hopper (41). The wood by-product introduced is rotated by the transfer screw. The wood by-products to be transferred are transferred to the stack 60 as shown in FIG. The wood by-products that are transferred to the stack are accumulated in the stack for a period of time without being discharged to the outside.

The wood by-products first transported to the stockpile are not immediately discharged and accumulate inside the stockpile. Afterwards, the wood by-product flowing into the inlet 44 is accumulated in the stacking unit 60 in turn.

When the wood by-product is accumulated in the stacking portion 60, when heated to 230-320 ℃ by the heating unit 61 can be expanded while evaporating the water of the wood can improve the water absorption of the wood by-product. When pressed at room temperature and normal pressure through the extrusion unit under high pressure by the heating unit and compression by the transfer screw, the wood by-product is foamed. The heating section of the stack can kill bacteria and re-nematodes in the wood by-products.

Blowing agents can be added to foam wood by-products more efficiently. As the blowing agent, either sodium bicarbonate or azodicarbonylamide is used. This foams the wood by-products in the same way as the fried rice made with fried rice.

When the foamed wood by-products are extruded through the extrusion part, the foamed wood by-product is cut to a certain size by the cutting part 80. Since the cutting portion is rotated by a plurality of cutting edges at intervals maintained by the gap holder, the extruded wood by-product is cut to the size of the gap of the cutting edges. Dense spacing of cutting edges in the cuts eliminates all nematodes in the pine. The foamed wood by-products are finely chopped using a cut and mixed with compost to control the moisture of the compost and at the same time use itself as compost.
