DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described with reference to the accompanying drawings.
[0010]
As shown in FIGS. 1 to 5, the vehicle 1 is equipped with a tank 3 for storing compost 2. As the compost 2 stored in the tank 3, for example, a granular material is used. The tank 3 includes a pair of inclined plate portions 4 and 4 that are arranged so that the interval is narrowed downward, and triangular plate portions 5 and 5 that are provided so as to cover the front and rear of the inclined plate portions 4 and 4. The side plates 6 and 6 are connected to the upper portions of the inclined plate portions 4 and 4, and the upper surface portion 7 covers the portion surrounded by the side portions 6 and 6 and the triangular plate portions 5 and 5.
[0011]
A spray screw 9 for transferring the compost 2 in the tank 3 to a tank outlet 8 formed at the bottom of the rear triangular plate 5 is disposed at the bottom of the tank 3. The screw 9 includes a rotary shaft 10 that is rotatably supported at the bottom of the tank 3 along the front-rear direction, a spiral blade member 11 that is attached to the rotary shaft 10, and a rear shaft that drives the rotary shaft 10 to rotate. And a motor 12 (hydraulic motor) provided on the side triangular plate portion 5.
[0012]
Further, a stirring mechanism 13 is provided in the tank 3 to dispose the bridge of the compost 2 generated in the tank 3 so as to be positioned above the screw 9. The agitating mechanism 13 is disposed in the tank 3 along the front-rear direction and is rotatably supported by the front and rear triangular plate portions 5 and 5 and is attached to the rotational shaft 14 at a predetermined interval in the axial direction. A mold stirring rod 15 and a motor 15 (hydraulic motor) for driving the rotary shaft 14 are provided.
[0013]
The agitation mechanism 13 is normally stopped. When a compost application worker holds a spray hose 37 (to be described later) and sprays compost inside the greenhouse or the like, compost is introduced from the tip of the hose 37. When it is no longer sprayed, it is appropriately operated remotely by operating an operation panel such as a radio control or a remote controller carried by the operator so as to break the bridge of the compost 2 in the tank 3.
[0014]
A discharge cylinder 16 is attached to the tank outlet 8. The discharge cylinder 16 has a lid 17 at its rear end and a discharge port 18 below. The rotating shaft 14 passes through the discharge cylinder 16 and is pivotally supported by a lid 17 at the rear end. As shown in FIG. 5, flat paddles 19 arranged at intervals of 180 degrees are attached to the rotating shaft 14 in the discharge cylinder 16. The paddle 19 scrapes off the compost 2 transferred into the discharge cylinder 16 through the tank outlet 8 to the lower discharge port 18.
[0015]
The discharge port 18 is provided with a rotary valve 20 for discharging the compost 2 while shutting off air inside and outside the tank 2. As shown in FIG. 5, the rotary valve has a casing 21 made of a cylindrical body that is horizontally disposed along the vehicle width direction. The casing 21 has a connection port 22 connected to the discharge port 18 at an upper portion thereof, and lid portions 23 and 23 at left and right ends. A rotor 24 is rotatably accommodated in the casing 21.
[0016]
The rotor 24 includes a rotating shaft 25 that is pivotally supported through the left and right lid portions 23, 23, and a plurality (eight in the illustrated example) of paddles 26 that are radially attached to the rotating shaft 25. A rotation drive motor 27 (hydraulic motor) is connected to the rotation shaft 25. Inlets 28 and 29 and outlets are formed below the left and right lids 23 and 23. Connected to the inlet 28 and the outlet 29 is a pressurized air passage 30 for discharging a part of the compost 2 in the valve 20 by aerodynamic force.
[0017]
According to the rotary valve 20, the compost 2 supplied from the connection port 22 along with the rotation of the rotor 24 is sequentially transferred downward by the paddle 26, and compost between the paddles 26 and 26 at the inlet 28 and outlet 29 portions. 2 is discharged from the casing 21 by the aerodynamic force of the pressurized air passage 30. At this time, each paddle 26 blocks air from the connection port 22 side and the inlet 28 and outlet 29 side of the casing 21, so that the pressurized air flowing through the pressurized air passage 30 does not enter the tank 3.
[0018]
In FIG. 5, the pressurized air passage 30 includes a downstream-side pressurized air passage tube 31 connected to the outlet 29 of the rotary valve 20 and an upstream-side pressurized air passage tube 32 connected to the inlet 28 of the rotary valve 20. As shown in FIG. 4, the upstream pressure air passage pipe 32 is provided with a blower 33 that generates pressure air. The blower 33 is driven by a motor 34 (hydraulic motor). The downstream pressure air passage pipe 31 and the upstream pressure air passage pipe 32 are connected by a secondary air pipe 35 that bypasses the rotary valve 20.
[0019]
The secondary air pipe 35 further applies pressure to the compost 2 discharged from the outlet 29 of the rotary valve 20 to improve the mixing of the air and the compost 2 and to increase the pumping force of the compost 2. In addition, a spray hose 37 that guides the compost 2 to a desired location is connected to the downstream-side compressed air passage pipe 31 via a joint coupling 36. The operator holds the tip of the spray hose 37, and the compost spraying work is performed inside the greenhouse.
[0020]
As shown in FIG. 2, a compost inlet 38 formed in a rectangular shape is opened in the upper surface portion 7 of the tank 3 so as to be offset in the vehicle width direction. Further, a passage 39 for workers is laid along the vehicle length direction on the tank upper surface portion 7 on the opposite side to the input port 38 in the vehicle width direction. The passage 39 is configured by attaching an iron plate or the like with anti-slip irregularities attached to the tank upper surface portion 7. The passage 39 can be accessed from the rear of the vehicle 1 by a ladder 40 attached to the rear triangular plate portion 5 of the tank 3.
[0021]
The inlet 38 of the tank upper surface portion 7 is opened and closed by a cantilever canopy cover 41. The canopy cover 41 is formed in a mountain shape as shown in FIGS. 7 and 8, and has a pipe-shaped frame 42 inside, and is configured by stretching a vinyl film 43 or the like on the frame 42. . As shown in FIG. 2, the canopy cover 41 is provided with a plurality of (four in the illustrated example) support rods 44 extending toward the passage 39 at predetermined intervals in the vehicle length direction. The tip of each support rod 44 is pivotally supported by a bracket 45 provided on the side of the passage 39 of the tank upper surface portion 7 via a common pivot 46.
[0022]
The pivot 46 is rotated approximately 90 degrees by a motor 47 attached to the front triangular plate portion 5 of the tank 3. As a result, the canopy cover 41 that covers the charging port 38 of the tank 3 rotates about the pivot 46 to be in a substantially vertical state, and the charging port 38 is opened. Therefore, a large amount of the compost 2 can be input to the input port 38 at a time from the side of the vehicle 1 opposite to the canopy cover 41 in the vertical state by a bull tosa or the like, and workability is improved. At this time, the worker can also monitor the state of the input of the compost 2 by standing in the passage 39.
[0023]
Further, as shown in FIG. 6, a net member 48 is attached to the insertion port 38. The net member 48 includes a first pipe body 49 that spans the insertion port 38 in the vehicle width direction, a second pipe body 50 that spans the pipe body 49 in the vehicle length direction, and first and second pipe bodies. And a lattice network 51 provided in a portion partitioned by 49 and 50. The lattice net 51 is set to a size that prevents the worker from falling and allows the passage of the compost 2. Therefore, the compost 2 is put into the tank 3 through the net member 48, and the worker standing in the passage 39 does not fall into the tank 3.
