Description

  The present invention relates to a greening base material production system and a greening base material production method.

  Slopes such as embankments and cuts tend to become unstable over time, with weathering and erosion starting immediately after embankment and cuts. Therefore, it is necessary to protect the slope in order to preserve the state at the time of embankment / cutting. In general, a protection method called a vegetation method in which grass and trees are artificially planted on the slope is used. According to this vegetation method, it is possible to prevent the erosion of the slope and to green the slope.

  As one of the vegetation methods, there is a thick layer base material spraying method in which a layer of the thick layer base material is formed on the slope surface by spraying the thick layer base material on the slope surface. This thick layer base material spraying is to spray a thick layer base material from a spray nozzle and spray it onto a slope (see, for example, Patent Document 1).

The thick base material is mixed with wood chips obtained by pulverizing roots and felled trees, and powdered auxiliary materials are composted to make a greening base material. Produced by mixing appropriately. A conventional method for producing a greening base material consists of the following procedures.
1. Using a crusher, roots and felled trees are crushed to a few inches and chipped.
2.1. Stack up wooden chips in a mountain shape about 2m high.
3. 1. Lift a ton pack containing auxiliary materials with a forklift. Sprinkle on top of chip mountain.
4). 2. Backhoe Stir the chip pile and mix the wood chips and secondary materials.

And a third conveyor (for example, a belt conveyor 19) to be dropped from a green base material production system 10.

  According to the first aspect of the present invention, the root material and the felled tree are pulverized by the pulverizer 11 to produce the wood chips, and the produced wood chips are conveyed by the first conveyor, and the auxiliary material stored in the hopper 15 is collected. The auxiliary material is added to the wood chip by supplying it onto the first conveyor by the feeder 16. Then, the wood chip and the auxiliary material are received by the lower end of the second conveyor, conveyed upward by the second conveyor, dropped from the upper end to the lower end of the third conveyor, and further received by the lower end of the third conveyor. And a wooden chip and a subsidiary material can be mixed uniformly by conveying a subsidiary material upward with a 3rd conveyor, and dropping from an upper end part.

  According to a second aspect of the present invention, in the greening base material production system according to the first aspect, a powder pump is used for the feeder 16.

  According to the second aspect of the present invention, by using a powder pump for the feeder 16, it is possible to quantitatively add the powdery auxiliary material to the wooden chip, and to uniformly distribute the wooden chip and the auxiliary material. Can be mixed.

  According to the third aspect of the present invention, rooting and felled trees are pulverized by the pulverizer 11 to produce wood chips, and the produced wood chips are conveyed by the first conveyor, while the auxiliary material stored in the hopper 15 is fed to the feeder 16. Is supplied onto the first conveyor, receives the wooden chips and auxiliary materials from the first conveyor at the lower end of the second conveyor, transports them upward and drops them from the upper end, and lowers the second conveyor at the lower end of the third conveyor. It is a method for producing a greening base material characterized in that it receives a wood chip and a secondary material dropped from the upper end portion, transports them upward and drops them from the upper end portion.

And a wooden chip and a subsidiary material can be mixed uniformly by conveying a subsidiary material upward with a 3rd conveyor, and dropping from an upper end part.

  According to the present invention, since the wood chip and the auxiliary material can be mixed uniformly, there is no need to mix the wood chip and the auxiliary material using a forklift or a backhoe. In addition, the number of times of turning back can be reduced.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a schematic diagram of a greening base material production system 10 to which the present invention is applied. As shown in FIG. 1, the greening base material production system 10 includes a pulverizer 11, an auxiliary material addition device 13, and a mixing device 17.

  The crusher 11 produces wooden chips by crushing woody materials such as root removal, felled trees, and waste wood with a cutter (not shown). The produced wood chips are carried out from the carry-out conveyor 12 at the rear part of the crusher 11 to the auxiliary material adding device 13.

  The auxiliary material adding device 13 includes a belt conveyor 14, a hopper 15 disposed on the belt conveyor 14, and a feeder 16. The front part of the belt conveyor 14 is disposed below the rear end part of the carry-out conveyor 12, receives the wood chip from the carry-out conveyor 12, and conveys it to the mixing device 17 behind the auxiliary material adding device 13.

  The hopper 15 contains secondary materials. The auxiliary material is also called a fermented material, and has a role of fermenting wood chips into compost. The auxiliary material is, for example, powder such as peat moss, rice husk, rice bran. As the feeder 16, for example, a powder pump including a screw pump and an air pump (not shown) can be used. By the air pump, the auxiliary material can be sent from the hopper 15 together with the air to the screw pump, and the auxiliary material can be quantitatively carried out together with the air by the screw pump and supplied onto the belt conveyor 14. In addition, you may accommodate in the hopper 15 in the state which mixed the some secondary material to be used, and you may provide the some hopper 15 and the feeder 16 according to the kind of secondary material.

  The mixing device 17 includes a belt conveyor 18, a belt conveyor 19, and a scattering prevention cylinder 20. The belt conveyor 18 and the belt conveyor 19 are disposed obliquely. A lower end portion of the belt conveyor 18 is disposed below the rear end portion of the belt conveyor 14, and an upper end portion is disposed above the lower end portion of the belt conveyor 19. The upper end part of the belt conveyor 19 is arrange | positioned above the stock yard 30 which stores a greening base material.

  The belt conveyor 18 receives the wood chip and the auxiliary material from the carry-out portion of the belt conveyor 14 at the lower end portion, conveys it to the upper end portion, and drops it from the upper end portion to the lower end portion of the belt conveyor 19. The belt conveyor 19 receives the wood chips and auxiliary materials from the upper end of the belt conveyor 18 at the lower end, conveys them to the upper end, and drops them from the upper end to the stock yard 30.

  The anti-scattering cylinder 20 is provided above the lower end portion of the belt conveyor 19, and includes an upper opening into which the wood chips and secondary materials falling from the upper end portion of the belt conveyor 18 are placed at the upper portion, and a wood chip and It has a cylindrical shape with a lower opening for discharging the auxiliary material onto the belt conveyor 19. The anti-scattering cylinder 20 prevents the wood chips and the auxiliary materials falling from the upper end of the belt conveyor 18 to the lower end of the belt conveyor 19 from scattering.

Hereinafter, a method for producing a greening base material by the greening base material production system 10 will be described.
First, the pulverizer 11 crushes roots, felled trees, waste wood, and the like to produce wood chips, which are carried out from the carry-out conveyor 12 to the auxiliary material adding device 13.

Next, while transporting the wood chips by the belt conveyor 14 of the auxiliary material adding device 13, the auxiliary material is quantitatively supplied from the hopper 15 onto the belt conveyor 14 by the powder pump. Thereby, an appropriate amount of subsidiary material can be added with respect to the quantity of wooden chips.
Next, the wood chip and the auxiliary material are carried out to the mixing device 17.

  The wood chips and auxiliary materials carried out from the belt conveyor 14 are conveyed to the upper end by the belt conveyor 18 and dropped into the upper opening of the anti-scattering cylinder 20. The dropped wood chips and secondary materials are discharged from the lower opening of the anti-scattering cylinder 20. The discharged wood chips and auxiliary materials are conveyed to the upper end by the belt conveyor 19 and dropped on the stock yard 30.

  Since the wood chip and the auxiliary material are close in specific gravity, the wood chip and the auxiliary material are evenly mixed by the two drops by the belt conveyor 18 and the belt conveyor 19. Therefore, since the wood chip and the auxiliary material are accumulated in the stock yard 30 in an evenly mixed state, it is necessary to mix the wood chip and the auxiliary material of the stock yard 30 with the backhoe during composting. Absent.

  When the wood chip is composted, plant seeds, soil, fertilizer, bonding agent and the like can be mixed as appropriate to form a thick layer substrate and sprayed on the slope. In addition, since there is no trouble of mixing during composting of the wood chip, it may be sprayed on the slope before composting and composted on the slope.

  In the above embodiment, the belt conveyor is used as the first conveyor, the second conveyor, and the third conveyor, but the present invention is not limited to this, for example, instead of any or all of these, A conveyor such as a screw conveyor or a spiral conveyor may be used. When a screw conveyor or a spiral conveyor is used, the wood chips and the auxiliary materials can be stirred while being conveyed. Further, the gradient can be made larger than that of the belt conveyor, and the installation area can be reduced.

  Moreover, although the powder pump was used as the feeder 16, other arbitrary feeders 16 may be used as long as the auxiliary material which is powder can be carried out quantitatively from the hopper 15. In addition, it is needless to say that specific detailed structures and the like can be appropriately changed.

It is the schematic which shows the greening base material production system 10 of this invention.
