  The fermenting apparatus shown in Patent Document 1 has an advantage that piping for the entire mat can be easily performed by connecting the supply pipes of adjacent mats to each other when laying a mat with a supply pipe installed therein. is there. However, this fermenting apparatus requires complicated processing such as mounting holes and nozzle opening holes for inserting the supply pipe into the mat, and complicated work for inserting the supply pipe into the mounting hole. There are disadvantages such as an increase in cost, an increase in mat weight, and difficulty in laying work.

Also using the work vehicle such as "Bobcat" (registered trademark) and bucket Ttoroda, when performing vehicle operations unloading and extraction, or crosscut like compost (bucket work), the tire travels over the feed pipe In this case, since the tread pressure weight is directly applied to the supply pipe, there is a drawback that the supply pipe in the mat is likely to be deformed or damaged. Further, when the work vehicle moves on the upper surface, the mat is dragged rearward by the tire, and there is a disadvantage that the supply pipe is deformed or damaged, or the mat is peeled off. Therefore, the fermentation treatment apparatus using the mat having the above structure has a problem that it is difficult to perform a uniform fermentation treatment of a processed product over a long period of time.

In addition, since the caulking agent filled in the lateral space and the lower space prevents the processed material from entering the interior of the groove, it is easy to clean the surface material surface and air is ejected from the nozzle body adjacent in the groove direction. Can be supplied to the workpiece in a wide range by communicating with each other in the space above the groove.

An embodiment of the present invention will be described with reference to the drawings. FIG. 1 is an overall perspective view of a fermentation treatment apparatus 3 in which a plurality of supply pipes 1 for blowing air to the ground surface or floor surface are provided with a pipe interval, and a surface material 2 is laid in the pipe interval. FIG. 2 is a plan view showing the configuration of the main part of FIG.
FIG. 3 is a front view of FIG. FIG. 4 is a cross-sectional view taken along line AA in FIG. 2 and shows an enlarged view of the piping structure of the supply pipe 1 and the structure of the nozzle portion 4. FIG. 5 is a cross-sectional view taken along the line BB of FIG. 2 and shows the guard member 5 provided between the adjacent surface layer materials 2.

The configuration of the fermentation treatment apparatus 3 will be described with reference to FIGS. This fermentation treatment apparatus 3 is configured to spread a processed material on a wide surface layer surface formed by laying a plurality of plate-like surface layer materials 2 on a floor surface 6 formed on a flat surface having rigidity such as concrete. Air is supplied from the nozzle body 4 of the supply pipe 1 that is laminated and connected to the high-pressure air supply unit and is piped on the floor side with respect to the processed product to promote aerobic fermentation of the processed product.
And the surface material 2 is laid in each piping space | interval formed by piping the said several supply pipe | tube 1, and comprises a series of flat floor surfaces, work of fermentation processing promotion of a processed material, work of a bucket loader, etc. Work such as transportation and turn-over of processed products performed using a vehicle.

  The configuration of each part of the fermentation treatment apparatus 3 will be described. First, the supply pipe 1 is a rod-like pipe made of stainless steel or alkali-resistant synthetic resin material. In this embodiment, the pipe 1 is a thick pipe made of synthetic resin and having an outer diameter of about 15 to 20 mm, and has a rectangular surface layer. A plurality of nozzle portions 4 that are piped along the longitudinal direction of the material 2 and similar to that shown in Patent Document 1 are provided in the middle thereof with a predetermined air ejection interval (nozzle pitch), and the pipe tip is closed. ing.

As shown in FIG. 4, the nozzle body 4 is formed with a nozzle hole 7 having a small diameter for air ejection at the center, and a recess opening on the surface side of the nozzle hole 7 by enlarging the diameter of the nozzle hole. Counterbore 8 is formed. The counterbore hole 8 having a large diameter has a concave part in a polygonal shape in plan view, and a bottom part is formed by an inclined surface in which an upward nozzle hole 7 is expanded in a lower part of a standing wall that forms an inner peripheral wall in a side sectional view. Further, the nozzle body 4 is fixed by screwing into a mounting hole formed on the upper surface side of the supply pipe 1 for each nozzle pitch.
With this configuration, the nozzle body 4 is supported by straddling the counterbore 8 or coming into contact with a standing wall or a sloping surface when a thin strip of processed material enters or enters the recess. It is possible to prevent clogging of the nozzle holes due to the fine pieces entering the recesses. Accordingly, high-pressure air can be uniformly ejected from the nozzle holes 7 without hindering air from flowing upward from the nozzle bodies 4.

  The surface layer material 2 is a vertically long plate made of foamed synthetic resin having a certain elasticity and rigidity, and has a length (length) of 4000 mm, a width (width) of 200 mm, and a thickness of about 20 to 30 mm. As a result, when the surface layer material 2 is arranged and laid in a state where the vertical sides (long sides) are in contact with the floor surface 6, a flat surface layer material surface having a desired width can be easily formed. Moreover, the flat surface layer material surface formed in series as described above is provided with groove-shaped piping joints 11 for piping the supply pipe 1 at predetermined intervals. That is, the unit surface layer material surface within the pipe interval of the supply pipe 1 is formed by arranging a plurality of the same surface layer materials 2 divided into width and length that are easy to manufacture and lay construction. The manufacturing and laying work can be facilitated.

  Further, each surface layer material 2 made of a synthetic resin and divided and formed to have the above size can be bonded and fixed to the floor surface 6 with an adhesive so that the laying and fixing of the surface layer material 2 can be strengthened. In addition, the surface layer surface formed by laying and fixing the plurality of surface layer materials 2 has a certain elasticity and rigidity and is familiar with the irregularities of the tires of the work vehicle, increasing the surface friction, so that the tire for working vehicles and running It improves the grip performance and enables smooth running without slipping. It should be noted that the elasticity and rigidity of the surface layer material 2 is such that when the work vehicle rides and works, the surface layer material is not greatly elastically deformed and does not impair the grip of the tire, and does not cause breakage or cracking of the surface layer material. Further, there is a demand for a material that does not cause surface damage due to the tip of a working machine such as an excavator.

Therefore, the vehicle work which frequently performs forward / reverse travel and turning travel can smoothly travel on the surface of the surface layer material where compost is scattered and easily slips. Moreover, each surface material 2 fixed firmly prevents the deformation | transformation by the tuck accompanying the slip rotation of a tire, and peeling with the floor surface 6, and improves durability of a surface material.
Moreover, the surface layer material 2 of the embodiment enables low-cost mass production by reprocessing a waste synthetic resin material mainly composed of polypropylene, and has corrosion resistance, chemical resistance, oil resistance, and the like. At this time, by performing foaming processing, the weight of the material is reduced (for example, the specific gravity is 1 or less, such as a specific gravity of 0.65 to 0.79), the material used is reduced, and the workability such as cutting and nailing is performed. In addition, by improving the heat insulation and strength, and by incorporating an adjusting material such as olefin rubber, the grip performance with the tire of the work vehicle is enhanced. Moreover, when a granular material such as fine sand or waste mineral particles is mixed at a certain ratio, the strength and wear resistance can be improved, and the unevenness of the surface can be adjusted.

  In this example, a commercial product called “Ecoma Wood” (manufactured and sold by Sanin Create, Yonago City, Shimane) is used, and the stress values for bending, compression, longitudinal tension, and shear are abbreviated as wood. It is equivalent and is less likely to break after exceeding each yield point.

  Moreover, when forming the surface layer material surface on both sides of the supply pipe 1, the surface layer material 2 adjacent to the left and right sides of the supply pipe 1 is separated from each other by about 25 to 30 mm between adjacent long sides. Fix them side by side to form a tube installation gap). At this time, when the supply pipe 1 is inserted along the piping joint 11, a lateral space of about 5 mm is provided on the left and right sides of the supply pipe 1, and a vertical space of about 5 mm is provided within the height depending on the thickness of the surface layer material 2. ing.

  Therefore, the horizontal space and the lower space can be sufficiently and easily filled with a caulking agent such as an adhesive or silicon rubber from above the piping joint 11. As a result, the supply pipe 1 that is long in the vertical direction can maintain a predetermined lower space height at the joint 11 for piping, and can perform positioning and fixing with the left and right surface layer materials 2 and piping in the groove with high accuracy. Further, after the piping, the processing material can be prevented from entering into the interior of the groove by filling the caulking agent, and the processed material in the groove can be easily removed along the groove when cleaning the surface material surface.

  Further, the supply pipe 1 piped with an upper space in the joint 11 for piping relaxes the pressurization of the processed material in which the upper space is laminated, so that the counterbore 8 of the nozzle body 4 is strongly blocked. Therefore, air can be stably supplied from the nozzle hole 7 to the processed material. Furthermore, since the air ejected from each nozzle body 4 adjacent in the vertical direction can be communicated in the groove direction, the entire length of the piping and the joints 11 for piping is used to supply air to a processed material in a wide range and fermentation treatment. Can be promoted. Further, the supply pipe 1 prevents direct contact with the tire of the work vehicle by the piping joint 11, receives the treading pressure of the tire through the left and right surface layer materials 2 and the processed material on the groove, and passes through the caulking agent. Since it is supported, there is an advantage that deformation and breakage of the supply pipe 1 can be prevented over a long period of time.

And the supply pipe 1 installed in the joint 11 for piping as mentioned above is T type or L type with respect to the connection pipe 13 connected through the high pressure air supply apparatus 12 and the high pressure air supply pipe 12 to the base side. It is designed to be detachably connected via a joint 14 forming At this time, if the socket 15 is attached to the base of the supply pipe 1 in advance, the supply pipe 1 can be easily attached to the joint 14 via the socket 15 without forming a screw part.
The T-shaped joint 14 is connected to the supply pipe 1 in a state where a connection pipe 13 having a substantially pipe interval length is connected to the left and right, and an L-shaped joint (not shown) is provided at the outermost end of the connection pipe 13. By connecting 1, a series of pipes can be configured.

  Next, with reference to FIGS. 2-5, the construction example which installs the fermentation processing apparatus 3 comprised as mentioned above in the installation division of a building (compost) is demonstrated. First, in the installation section, the floor surface 6 is finished to a flat surface with concrete, and after applying an adhesive to a required portion of the floor surface 6, four surface layer materials 2 are arranged in a vertical direction on the coated surface. The surface layer material surface of the attached first district is formed and the surface layer material is laid. At this time, the surface layer material 2 can be laid by previously applying an adhesive to the back surface.

Next, when the adjacent second section is constructed, the adhesive is applied and the four surface layer materials 2 are pasted so as to form the joints 11 for piping between the surface layer material 2 of the first section. Similarly, by forming a joint 11 for piping between the second ward and the third ward, and repeating the same construction in the fourth and subsequent wards, formation of a flat surface material surface and piping spacing for all the installed wards The joints 11 for piping can be formed accurately for every time.
At this time, as shown in FIG. 2, the surface layer material 2 forms a piping joint 11 having a width for inserting and connecting the connecting pipe 13 along the base of the side body 16 such as a wall or a fence on the lateral side. Lay while positioning.

  In the laying operation as described above, as the surface layer material 2 is laid while being pressed, the adhesive pushed out from the side edge of the surface layer material 2 protrudes into the joint 11 for the pipe and rises up. In addition, there is an advantage that each tube can be mounted on the rising adhesive portion, and the positioning operation in the groove of each tube can be easily performed in the piping operation described later. In addition, it is desirable that a through hole 17 through which the high-pressure air supply pipe 12 is passed is formed in the side body 16 of the installation section in advance.

  Moreover, when laying a plurality of surface layer materials 2 as described above, it is desirable to lay them with a guard member 5 interposed between adjacent surface layer materials 2. The guard member 5 according to the embodiment has a rectangular cross-sectional shape made of a metal such as stainless steel or a synthetic resin that is relatively hard and has a pressure resistance, and is slightly smaller than the thickness of the surface material 2 (for example, 1 to 1). 2 mm) and a width of about 10 mm. In installing the guard member 5, first, the left and right surface layer materials 2 are laid on the floor surface 6 to which the adhesive is applied with the guard member 5 inserted. Next, the guard member 5 is inserted into the insertion interval where the adhesive that protrudes and rises like the groove is accumulated, and is pressed against the floor surface 6. At this time, if an adhesive is applied to the joint surface between the guard member 5 and the surface layer material 2 as necessary, the bonding can be performed without generating a gap therebetween.

  As a result, the upper surface of the guard member 5 suffices to have a height near the surface of the surface layer material 2, but slightly protrudes along the longitudinal direction of the surface layer material 2 as shown in the figure, so that the work vehicle extends along the longitudinal (longitudinal) direction. When bucket work such as compost turning back and supply taking out is performed, the edge of the bucket first comes into contact with the surface of the hard guard member 5 to prevent direct damage to the surface layer material 2. Further, since the work vehicle can slide the edge of the bucket on the surface of the guard member 5, various operations using the bucket can be efficiently performed. Moreover, the guard member 5 can reinforce the side of the surface material 2 to be joined adjacently, and can improve the grip with the tire.

  Since the fermentation treatment apparatus 3 constructed and configured as described above is bonded and fixed to the surface layer material 2 formed of a synthetic resin plate having a certain elasticity and rigidity by providing joints 11 for piping, each supply pipe 1 The pipe is firmly fixed in a state protected by the surface layer material 2, and the air ejected from each nozzle body 4 is evenly supplied from the lower part of the stacked processed products. In addition, the surface layer material 2 made of synthetic resin laid on the floor surface 6 becomes a heat insulating material, promotes an increase in the fermentation temperature of the processed material, can perform aerobic fermentation uniformly in a wide range, and can produce high-quality compost, etc. Processed products can be produced efficiently. In addition, the supply pipe 1 is clogged because the nozzle body 4 has a counterbore hole 8 that opens upward in the nozzle hole 7 and is disposed below the surface material surface in the joint 11 for piping. Is prevented and the high-pressure air is smoothly ejected, so that the aerobic fermentation treatment in which the maintenance work of the nozzle portion is saved can be efficiently and inexpensively performed.

  In general, the work vehicle enters from the open entrance of the side body 16 and performs the work of turning back the processed material by forward and backward travel, so that each supply pipe 1 is stepped on by the wheel along the travel direction of the work vehicle. It is desirable to do piping so that there is no. Moreover, although the fermenting processing apparatus 3 of the example of illustration showed about the example which ferments the compost installed in the composting house, it can also be easily installed in the outdoor ground surface, In this case, the sheet | seat for overlays is used. When the surface layer material 2 is laid on the floor and fixed to the ground by an anchor bolt or a fixing means such as a stop pile, the fermentation treatment apparatus 3 can be easily installed and removed. In addition, it is desirable to cover the processed products to be laminated with a heat insulating sheet from above. Moreover, a processed material can perform the fermentation process and drying process with respect to various organic substance, without being limited to compost.

It is a perspective view which shows the state which installed the fermentation processing apparatus of this invention in the compost house. It is a top view which shows the structure of the principal part of FIG. It is a front view which expands and shows the structure of the principal part of FIG. It is the sectional view on the AA line of FIG. FIG. 3 is a sectional view taken along line B-B in FIG. 2.
