Abstract

PROBLEM TO BE SOLVED: To simply carry out transshipping work of a water-permeable material (rice hulls) for a short time at a low cost by suctioning the water-permeable material (rice hulls) dispersedly loaded on a load-carrying platform of a conveying vehicle through a supply pipe by a negative pressure generated by a blower and continuously feeding it through a feed pipe. SOLUTION: When chaff 33 is transshipped from a dump truck 20, a surrounding plate of an opening surface at a rear side of a load-carrying platform of the dump truck 20 is removed and a conducting body 13 is attached to the opening surface. Whereas, a supply pipe 14 is connected to an air feed port of the conducting body 13 and a suction port of a blower 23. A feed pipe 16 is connected to an air feed port of the blower 23. A general purpose engine 24 is operated in this state to rotate the blower 23 and at the same time, the load-carrying platform of the dump stuck 20 is slightly inclined. So, a negative pressure is generated in an internal space of the conducting body 13 by a rotation of the blower 23 and the chaff 33, etc., on the load- carrying platform are dropped off by the own weight and are continuously suctioned. The chaff 33 are transshipped to a hopper 5 of a material closed conduit formation working machine 1 through the supply pipe 14, the blower 23, the feed pipe 16 and a separator 17.

As shown in the drawing, a work machine 1 towed by a tractor T has a pipe P as a culvert forming material wound around a reel 3 on a constituent frame thereof, and the constituent frame further includes a subsoiler. A slit forming knife 4 called a so-called bullet or knife is attached. This slit forming knife 4
Introduces the pipe P from the reel 3 into the slit-shaped space formed in the field, supplies water-permeable material such as rice hulls from the hopper 5 mounted on the working machine 1 to the slit-shaped space, and supplies the water to the space above the culvert pipe. It forms a layer having excellent water permeability. The rollers 7 and the like are provided so that the rice hulls and the like that have become layers can be compressed from above to increase the density.

In the underdrain formation working machine having the above-described structure, a layer having excellent water permeability is formed vertically below the surface of the cultivated soil by using a knife or the like, and a drainage space is formed at the lower end thereof to facilitate drainage in the horizontal direction. This is the purpose, and it is often used for paddy crop rotation and field rotation. It forms a layer with excellent water permeability (also known as a hydrophobic layer), so that the space does not collapse due to earth pressure, etc., and that excess water in the soil can be quickly drained. In addition, the slit-shaped space is filled with a water-permeable material such as rice husk having excellent water permeability. Since this filling also needs to have a high density, pressing with a roller or the like from above the filled permeable material with a strong pressure is performed.

Conventionally, in such a material culvert working machine, replenishment of a permeable material such as chaff to the hopper 5 has been performed as follows.

A plurality of flexible containers are loaded on a transport vehicle, transported to the vicinity of the field, and loaded on the underdrain forming machine. The rice husks are collected in a rice mill called a rice center and filled into flexible containers. As shown in FIG. 7, the permeable material carried into the field is lifted by a flexible crane or the like by a flexible crane F or the like and brought up above the hopper 5.
By opening the bottom of the flexible container F in this state, the hopper 5
Drops inside and is transshipped.

[0006] Regarding the above-mentioned replenishing operation of the permeable material, for example, considering rice husks, in addition to transportation by a transport vehicle, various types of loading of F into a flexible container in a rice mill, lifting of the flexible container F in a field, and opening of the bottom of the flexible container. The operation has to be performed, and a great deal of time has been spent. Also,
It is necessary to arrange a hydraulic crane and the like for suspending the flexible container F every time transhipment. Further, when the rice husks are put into the hopper 5, the bottom of the flexible container F is opened. Without this, it is often necessary to break down the rice husks by hand, which has made it difficult to improve work efficiency from this point of view.

It is completed only by locking. The removal of the derivative 13 follows the reverse process.

In the present embodiment, a flexible pipe made of a synthetic resin or the like is selected as the supply pipe 14. This supply pipe 14 has one end of the derivative 13 described above.
Is connected to the supply port 13b.

Next, the blower unit 15 is provided with a blower 23 and a general-purpose engine 24 as driving means for driving the blower 23 mounted on a carriage 22. Note that the carriage 22 is provided with a handle 22a and can be transported freely. As is clear from FIG. 4, as the blower 23, for example, a turbo centrifugal fan is employed. The input shaft 23 of this blower 23

The belt 25 is wrapped around b and the pulley 23b, and the engine output is transmitted to the blower 22 at a predetermined reduction ratio. As shown in FIG. 1, a long exhaust pipe 27 is attached to an exhaust port of the general-purpose engine 24.

The other end of the supply pipe 14 is connected to an intake port 23c of the blower 23, and communicates the intake port 23c with the supply port 13b of the derivative 13.

The delivery pipe 16 is made of a thin steel pipe or the like, and has one end having a blow port 23d of the blower 23 (FIG. 4).
See). The delivery pipe 16 has a length that extends above the hopper 5 of the permeable material (rice hull) transfer machine 1, and is supported near the upper end by the upper opening edge of the hopper 5.

The separator 17 is connected to the other end, that is, the upper end, of the delivery pipe 16 and separates the air from the permeable material (rice husk), and is configured as follows.

As shown in FIG. 5, the separator 17 has a tubular member 29 made of a thin steel pipe or the like and connected to the delivery pipe 16 at one end. An opening 29a is formed in the outer peripheral portion of the other end of the cylindrical member 29. In the tubular member 29, a mesh member 30 is arranged downstream of the opening 29a in the air blowing direction. This mesh member 30
Has a mesh smaller than the minimum diameter of the permeable material (rice hull), allows only air to pass through, and prevents passage of the permeable material (rice hull). The guide tube 31 is attached to the opening 29a downward. Although the above-described separator is used in the embodiment of the present invention, the present invention is not limited to this, and a cyclone separator may be used.

Subsequently, the permeable material (rice hull) 33 is transferred from the dump truck 20 by the permeable material (rice hull) transfer device having the above-described configuration.
The operation of transshipping is briefly described.

As shown in FIG. 1, a permeable material (rice husk) 33
Are loaded into a field in a state where they are stacked in a tall box-shaped enclosure 35 installed on the bed of the dump truck 20. When the permeable material is rice husk, the dump truck 20 gets into a rice mill called a rice center with the enclosure 35 attached, and receives the rice husks discharged from the rice mill directly onto the bed and loads it.

Dump truck 20 loaded with water permeable material (rice husk)
Arrives at the field, the surrounding plate of the opening surface 20a on the back side of the loading platform is removed. Then, the derivative 13 is mounted on the opening surface 20a by the above-described procedure. On the other hand, the derivative 1
The supply pipe 14 is connected to the third supply port 13b and the intake port 23c of the blower 23. Further, the delivery pipe 16 is connected to the blow port 23 d of the blower 13. At this time, the delivery pipe 16
The separator 17 is attached. This makes it possible to transship.

In the above state, the general-purpose engine 24 is operated, and the blower 23 is rotated. At the same time, the bed of the dump truck 20 is slightly inclined in accordance with the decrease in the chaff. Then, the water-permeable material (rice hull) on the carrier flows toward the rear of the carrier, and is guided into the derivative 13 by the suction force together with the weight. Negative pressure is generated in the inner space of the derivative 13 by the rotation of the blower 23 due to the operation of the engine, and the rice hulls and the like on the bed are continuously sucked as the weight falls, and the supply pipe 14, the blower 23, the delivery pipe 16, the separator After passing through 17, the hopper 5 of the material culvert forming work machine 1 is reloaded. Hereinafter, while gradually increasing the inclination angle of the loading platform of the dump truck 20, the operation is continued until the permeable material (rice hull) disappears from the loading platform.

As shown in FIG. 5, during the above operation, the delivery pipe 1
The permeable material (rice hull) blown out with the air through 6 is
The movement is blocked by the mesh member 30, falls down through the opening 29 a of the tubular member 29 and the guide cylinder 31, and accumulates in the hopper 5. The blast from which the water-permeable material (rice hulls) has been separated is discharged into the atmosphere through the end opening 29c of the tubular member 29.

[0026]

As described above, according to the water permeable material (rice hull) transfer apparatus of the present invention, the water permeable material (rice hull) piled up in a carrier or the like in bulk is generated by the negative pressure generated by the blower. Aspirated through the supply tube and continuously delivered through the delivery tube. Therefore, the transhipment operation of the water permeable material (rice husk) can be completed easily in a short time and at low cost. In addition, regarding rice husks, rice mills do not require packing work into flexible containers, and there is no need to handle flexible containers at all. The time from loading the truck to transfer to the material culvert work machine is reduced, and labor costs are reduced, so total cost is reduced and work efficiency is increased.
Also, if the receiving port of the derivative is adapted to fit into at least one opening surface of the carrier, and the derivative is installed on the opening, if the loading platform is tilted, the water-permeable material directly enters the derivative. Be efficient. However, although the work efficiency is slightly reduced, the derivative is assumed to be small, and the worker handles the derivative by himself on the carrier and handles the water-permeable material (rice husk).
May be sucked.

Further, if a separator is provided at the other end of the delivery pipe to separate the air from the permeable material (rice husk), the permeable material discharged from the delivery pipe together with the blast is separated from the blast by the separator. Fall. In other words, if the rice husk is blown into the hopper together with the air blow, the rice husk may be scattered around, but this is prevented by installing the separator. Furthermore, the separator has a tubular member connected to the delivery pipe at one end and having an opening formed on the outer periphery of the other end, and a mesh smaller than the minimum diameter of the water-permeable material (rice husk). It is preferable to employ a member comprising a mesh member disposed in the tubular member at a position downstream of the opening in the air blowing direction. Such a separator is simple in construction, low in cost,
There is no risk of failure.
