It is something to drop. For example, locally generated soil collected from the plant growth base construction site as soil, polymer flocculant made of acrylic polymer as aggregate, and trees harvested from plant growth base construction site as plant fragment Use crushed pieces.

  As shown in FIGS. 1 to 5, the stirring vessel 4 is rotatably supported by the support 3. Both side walls 12; 12 of the stirring vessel 4 are made of flat plates formed in a substantially inverted trapezoidal shape. The upper side 13 of the side wall 12 has a horizontal line shape, the rear side 14 has a vertical line shape, and the lower side 15 is formed in a shape in which two semicircles curved downward are arranged side by side (see FIG. 5). The front side 16 of the side wall 12 is a side that connects the end portions 13e of the upper side 13 and the lower side 15; The front side 16 is formed in an inclined shape that inclines from the end 15e of the lower side 15 to the end 13e of the upper side 13 while inclining to the side opposite to the rear side 14 side. That is, the upper side 13 and the lower side 15 extending forward from the upper and lower ends 14a; 14b of the rear side 14 of the vertical line shape of the side wall 12 are longer in the upper side 13, and the front side 16 of the side wall 12 is From the terminal part 15e of the short lower side 15 to the terminal part 13e of the upper side 13 longer than the lower side 15, it is formed in an inclined shape that linearly inclines and rises forward.

Are connected to each other, and the front sides 16; 16 are connected to each other by a flat front wall 19. Therefore, the front wall 19 of the stirring tank is formed by a flat inclined wall 19A that is inclined in a direction away from the rear wall 17, that is, upward and forward from the front end 18a of the bottom wall 18. That is, the stirring tank 4 is formed in a rectangular box shape with an open top having a substantially inverted trapezoidal longitudinal section having an inclined wall 19A at the front.

  Stirring rods 20; 20 are respectively installed on the two semi-cylindrical bottom inner sides 18b; 18b of the stirring tank 4 formed by the two semi-cylindrical bottom walls 18 (see FIG. 6; FIG. 7). The stirring rod 20 is provided with stirring blades 22 on the outer peripheral surface of a rotating shaft 21 provided extending between both side walls 12; 12 of the stirring tank 4, and both ends of the rotating shaft 21 are outside the both side walls 12; Are supported rotatably by the bearing portions 23; The rotation control of the motors of the two stirring rods 20; 20 is synchronously controlled by the synchronization device 25.

  The support 3 is formed by a moving body 33 and a moving guide 2A for the moving body 33. The moving guide 2 </ b> A is formed by two rails 30; 30 that extend in the left-right (width) direction on the loading platform 2 of the truck 1 and are provided in parallel with each other on the front and rear on the loading platform 2. The moving body 33 includes a plurality of wheels 31 that support the agitation tank 4 at the upper portion and slide on the two rails 30; 30 at the lower ends of both ends 32; 32 corresponding to the front and rear of the loading platform 2 of the truck 1. . Therefore, the moving body 33 can move along the left-right direction on the loading platform 2 of the truck 1 by moving the wheels 31 of the moving body 33 in the rails 30; 30 as the movement guide 2A. That is, the wheel 31 and the rail 30 constitute a moving mechanism for the moving body 33. The support 3 is provided on a base portion 35 formed on the loading platform 2, and the movable body 33 is positioned and fixed to the base portion 35 by a positioning and fixing portion 36. The positioning and fixing portion 36 is inserted into, for example, a fixing bracket 37 provided at the lower portion of the moving body 33, a bolt mounting hole 38 formed in the base portion 35, and a through hole 37a formed in the fixing bracket 37 to be bolt mounting holes. The bolt 39 is fastened to the bolt 38 (see FIG. 4). That is, the support 3 formed by the moving body 33 and the moving guide 2A is mounted on the loading platform 2 of the truck 1, and the moving body 33 positions the stirring tank 4 on the center side of the loading platform 2 as will be described later. It is configured to be movable between a transfer position and a use position where the stirring tank 4 is positioned on the side of the loading platform 2. The movable body 33 is configured to be positioned and fixed to the loading platform 2 at the transport position and the use position by the positioning fix section 36A for the transport position and the positioning fix section 36B for the use position. That is, at the time of conveyance, the moving body 33 is positioned and fixed to the right side from the center of the loading platform 2 of the track 1 by the positioning fixing portion 36A, and the stirring tank 4 is positioned on the center side of the loading platform 2 of the track 1. Further, when the plant growth base material 100 is used for manufacturing and discharging, the movable body 33 is positioned and fixed to the left side of the center of the loading platform 2 of the truck 1 by the positioning fixing portion 36B, and the stirring tank 4 is loaded on the loading platform of the truck 1. 2 on the left side.

  Bearing parts 41; 41 that rotatably support the rotation center shaft 40 of the agitation tank 4 are provided at the upper portions of both ends 32; 32 of the moving body 33. For example, as shown in FIG. 1B, the support structure of the rotation center shaft 40 of the stirring tank 4 is provided so that both end sides of the rotation center shaft 40 protrude downward from the lower portions of the side walls 12; 12 of the stirring tank 4. The fixed bracket 45; 45 has a structure that is rotatably supported by the bearing hole 47; 47 of the bearing portion 41; 41 through the through hole 46; 46 of the 45, and the rotation center shaft 40 and the fixed bracket 45 are welded. The rotation center shaft 40 and the agitation tank 4 are integrated by being fixed to each other by fixing means such as the part S. Therefore, as shown in FIG. 1A, the stirring tank 4 is formed on the loading platform 2 of the truck 1 by the rotation center shaft 40 rotating through the bearing portion 41 from the upright state in which the opening 11 faces upward. Rotating leftward, the opening 11 is turned sideways (see FIG. 3). That is, in the stirring tank 4, the side walls 12; 12 are positioned before and after the loading platform 2 of the truck 1 and the front wall 19 is positioned on the left side of the loading platform 2 of the truck 1. The front wall 19 side is rotated downward in the left direction of the loading platform 2 around the rotation center axis 40. An air spring 50 is attached to the facing portion 48 of the moving body 33 facing the bottom wall 18 of the stirring tank 4 in the upright state. The air spring 50 is fixed to the facing portion 48 by a fixing means such as welding or a bolt via a bracket 50a, for example. The air spring 50 includes an air bag that expands and contracts by air, for example, and reduces the collision impact between the bottom wall 18 of the agitation tank 4 and the facing portion 48 of the moving body 33 by adjusting the amount of air in the air bag. It functions as a shock absorbing material. The agitation tank 4 is configured to be rotatable by its own weight as will be described later. However, if the agitation tank 4 does not rotate by its own weight for some reason, air is introduced into the air bag of the air spring 50 to remove the air bag. By inflating, the air bag presses the bottom wall 18 of the agitation tank 4 and assists the start of rotation of the agitation tank 4, so that the agitation tank 4 can be rotated when a rotation failure occurs. That is, the air spring 50 also functions as a stirring tank rotation compensation means. In other words, the air spring 50 forms a seating portion in the upright state of the stirring tank 4 and reduces the impact caused by the collision between the stirring tank 4 and the moving body 33 when the stirring tank 4 returns from the sideways state. And when stirring tank 4 does not rotate with dead weight, stirring tank 4 can be rotated.

  As shown in FIG. 5A, the rotation center shaft 40 is set at a position deviating from the center of gravity G of the stirring tank 4. That is, for example, the stirring tank 4 is provided at a position closer to the rear wall 17 side of the stirring tank 4 by a distance a than the center of gravity G of the rotation center shaft 40, so that the stirring tank 4 has its own weight (the weight of the stirring tank 4 itself + The weight of the plant growth base material manufactured in the stirring tank 4 is set so as to be rotatable. Then, the end hook 55 of the chain 54 of the chain block 53 is inserted into the locking hole 52 of the locking member 51 provided on the lower side of the rear part of the stirring tank 4 so that the stirring tank 4 does not rotate when the vehicle moves and when stirring. By engaging and pulling the stirring tank 4 with a chain block 53 as a pulling means, the posture of the stirring tank 4 is maintained in an upright state with the opening 11 facing upward. The pulling force of the stirring tank 4 by the chain block 53 is hung downward by the force direction changing shaft fulcrum 53X. When the plant growth base material 100 is discharged, the stirring tank 4 can be gradually rotated by adjusting the chain 54 of the chain block 53 to be gradually pulled out. When the stirring tank 4 rotates 45 degrees and the outer surface 19f of the front wall 19 collides with the left edge 35a of the base portion 35 corresponding to the left end of the loading platform 2 of the truck 1, the stirring tank 4 does not rotate any more. In this state, the inner surface 19u of the front wall 19 becomes an inclined surface having an inclination angle of about 45 degrees from the bottom side to the outside downward (see FIG. 3). Therefore, the plant growth base material 100 inside the agitation tank 4 naturally flows down on the inclined surface and falls onto the belt 10 a of the belt conveyor device 10 installed on the lower left side of the track 1. In addition, as shown in FIG. 7, the spill-proof iron plate 10b is provided so that the plant growth base material 100 may not spill from the belt 10a of the belt conveyor apparatus 10. FIG.

  The manufacturing method of the plant growth base material 100 is demonstrated. First, when the truck 1 is operated and the production apparatus is transported to the site, the state shown in FIG. 1, that is, the stirring tank 4 is pulled up by operating the chain block 53 to bring the stirring tank 4 upright. The posture of the stirring tank 4 is maintained so as to be in a state (that is, pulled by the chain block 53 so that the stirring tank 4 does not rotate), and the support 3 is positioned on the right side of the loading platform 2 of the truck 1. After the agitation tank 4 is set to be located in the vicinity of the center between the left and right sides of the loading platform 2, the lower frame 56 and the base portion 35 of the moving body 33 are fixed by the positioning fixing portion 36 </ b> A located on the right side of the loading platform 2. Keep it as When arriving at the site, the moving body 33 is moved to the center side of the loading platform 2, the stirring tank 4 is positioned on the left side of the loading platform 2, and the moving body 33 is fixed to the base portion 35 by the positioning fixing portion 36B (FIG. 2; (See FIG. 4). In this state, the soil generated in the field is put into the agitation tank 4 by a construction work machine such as a backhoe 60, and water is pumped from the water tank 8 to the water measuring tank 7 by a pump not shown in the figure, and is measured in the water measuring tank 7. After the water necessary for the kneading is put into the stirring tank 4, the control device 5 is operated to drive the motor 24 of the stirring bar 20, and the stirring bar 20 is rotated and put into the stirring tank 4. Start kneading the generated soil and water. Thereafter, the plant fragments are put into the stirring tank 4 and stirred until the plant fragments are evenly mixed. Next, a predetermined amount of aggregating agent is put into the agitation tank 4 and stirred until the generated soil aggregates. Furthermore, a bonding agent, a fertilizer, and seeds as necessary are added and stirred. And after producing the plant growth base material 100 by complete | finishing stirring, the chain block 53 is operated, the chain 54 is gradually pulled out, the stirring tank 4 is rotated gradually, the stirring tank 4 is set to the sideways state. Thereby, the opening part 11 of the stirring tank 4 faces sideways, and the plant growth base material 100 inside the stirring tank 4 slides on the inclined surface which is the inner surface 19u of the front wall 19 of the stirring tank 4 and flows down naturally. 1 falls on the belt 10a of the belt conveyor device 10 installed on the lower left side. The plant growth base material 100 that has fallen on the belt 10a is transported and loaded onto a loading platform of a dump truck (not shown) by the belt conveyor device 10, and the plant growth base material 100 is transported to the plant growth base formation place by this dump truck. Needless to say, the manufacturing operation of the plant growth base material 100 may be performed after the truck 1 transports the manufacturing apparatus to the plant growth base construction site.

  According to the first embodiment, since the manufacturing apparatus is mounted on the loading platform 2 of the truck 1, the movement of the manufacturing apparatus is facilitated. Further, the movable body 33 is configured to be movable by a moving guide 2A between a transporting position where the stirring tank 4 is positioned on the center side of the loading platform 2 and a usage position where the stirring tank 4 is positioned on the side of the loading platform 2. In addition, since the movable body 33 can be positioned and fixed to the loading platform 2 at the transport position and the use position by the positioning and fixing portions 36A and 36B, a stable loading state can be maintained at the time of transport. Stability during traveling of the truck 1 can be ensured without impairing the balance during traveling. In addition, traveling stability and safety when transporting on public roads are improved. In use, after the plant growth base material 100 is manufactured in the stirring tank 4, the plant growth base material 100 can be easily discharged out of the loading platform 2 by rotating the stirring tank 4 and putting it in a sideways state. Further, as the stirring tank 4, a box-shaped thing with a closed bottom having an opening 11 at the top is used, and the stirring tank 4 is in an upright state in which the opening 11 is directed upward and the opening 11 is in the lateral direction. The structure for supporting the water-sealing performance of the agitation tank 4 is unnecessary, and the amount of water during the agitation is not required. Can be accurately maintained, so that a high-quality plant growth base material 100 can be manufactured. In addition, the rotation center shaft 40 is set at a position deviating from the center of gravity G of the stirring tank 4, and the stirring tank 4 is set so as to be rotatable by its own weight, so that the stirring tank 4 is rotated from the upright state to the sideways state. At this time, it is not necessary to apply a rotational force to the agitation tank 4, and power for rotating the agitation tank 4 can be eliminated. Further, by pulling the stirring tank 4 with the chain block 53, the posture of the stirring tank 4 is maintained in an upright state with the opening 11 facing upward, and then the moving body 33 is moved to the left side of the loading platform 2 after the stirring is completed. Then, by gradually pulling out the chain 54 of the chain block 53, the agitation tank 4 can be gradually rotated, and the collision impact between the agitation tank 4 and the left edge 35a of the base portion 35 can be mitigated, Safety can be improved. Further, in the sideways state of the stirring tank 4, the plant growth base material 100 is naturally flowed by sliding on the inner surface 19 u of the front wall 19 set to an inclined surface with an inclination angle of about 45 degrees from the bottom side to the outside downward.
