  In farmland such as upland farming, drainage management using underdrains is performed for the purpose of stabilizing the yield. Underdrains are drainage pipes buried at regular intervals in poorly drained field crops such as clay, peat, and volcanic ash. When burying a culvert drainage pipe, after excavating a groove of a predetermined width with a power shovel, etc., lay the culvert drainage pipe in the excavation groove, and then filling it with hydrophobic material such as crushed stone and shells and topsoil from above Do the return.

As shown in FIG. 5, the backfill material charging vehicle described in the publication is configured by installing a screw conveyor 100 along the width direction of the loading platform at the rear of the loading platform such as a dump truck. When the hydrophobic material is introduced into the excavation groove, the hydrophobic material mounted on the loading platform is moved by the slewing conveyor 100 while traveling along the excavation groove so that the insertion portion 102 of the screw conveyor 100 is positioned above the excavation groove. This is done by guiding it to the input section and dropping it into the lower excavation groove.

As shown in FIG. 1, the hydrophobic material charging vehicle 10 of this embodiment is configured by installing a hydrophobic material charging device 14 in a crawler type vehicle 12. The crawler type vehicle 12 is a so-called carrier dump provided with a rubber crawler (endless track) 12A, and can freely move on agricultural ground such as upland field.

  The crawler type vehicle 12 is provided with a loading platform 12B having a rear end as a fulcrum. The loading platform 12B is moved to a desired inclination angle by a hydraulic cylinder installed between the lower portion and the vehicle body. It is possible and can be held, and is used as a storage portion for a hydrophobic material or the like. As shown in FIG. 2, in the opening at the rear part of the loading platform 12B, the hydrophobic material charging device 14 has a hook 16 provided at the upper end and a fixing screw 18 provided at the lower end of the loading platform 12B. It is fixedly attached to the rear part. The hook 16 is normally supported by a pin 25 projecting from an upper part of a loading platform side plate 27 to which a carrier dump tilt plate is attached. The lower portion of the loading device 14 is fixed by inserting and tightening fixing bolts and nuts 18 into screw holes (not shown) protruding from the lower portion of the loading platform side plate.

As shown in FIG. 1 to FIG. 3, in the hydrophobic material loading device 14, a box body 26 is formed by side plates 22 attached to both sides of the frame 20 and a back plate 24, and the box body 26 is the center. Composed. Inside the box body 26 is provided a supply port 28 for a hydrophobic material or the like formed by forming a steel plate in a substantially inverted trapezoidal funnel shape, and receives a hydrophobic material or the like sent out from the cargo bed 12B while receiving a hydrophobic material or the like to be described later. It can supply toward the transfer means. The lower surface of the supply port 28 is opened toward the transfer means, and can be supplied by dropping a hydrophobic material or the like into the transfer means.

A support frame 30 of a belt conveyor is formed at the lower part of the box body 26 by combining a plurality of steel members. The support frame 30 is connected to the lower part of the frame 20 to transfer a hydrophobic material or the like. The means are housed inside. Specifically, as shown in FIGS. 1 to 3, the support frame 30 is formed in a shape that extends from the lower portion of the box 26 to one side along the width direction of the vehicle. Inside the support frame 30, a belt conveyor 32 is disposed as a transfer means. As shown in FIG. 3, the driving source of the belt conveyor 32 is a motor 36 installed on a mounting stay 34 at the right end of the support frame 30, and the rotational force of the motor 36 is transferred to the belt conveyor via a V belt 39. The drive pulley 32B of 32 is rotated in the direction of arrow A, and the driving force is transmitted to the belt 32A.
The belt conveyor 32 is provided so as to be inclined such that a charging portion 32C of a hydrophobic material or the like with respect to the excavation groove is located below the supply port 28 of the hydrophobic material or the like, and has an inclination angle α. For this reason, when a crushed stone, a hydrophobic material such as a shell, volcanic ash, sand, or the like is transported by the belt conveyor 32, the hydrophobic material or the like is easily transported to the input portion 32C. It can be used effectively, and the load on the motor 36 can be reduced. A switch box 37 for turning on / off the motor 36 is attached to the support frame 30.

As shown in FIGS. 3 and 4, a diaphragm 38 (shaded portion) as a vibration mechanism is provided in the vicinity of the supply port 28 for a hydrophobic material or the like. As shown in FIG. 3, the diaphragm 38 is attached to the frame 20 via a spring 40 so as to be movable up and down, and is a motor (engine) installed on the extending portion 20 </ b> A of the frame 20. 42 is connected via a V-belt 43, and the driving force of the prime mover 42 is converted into a force that moves up and down by a cam (not shown) so that the diaphragm 38 can continuously vibrate up and down. Yes. As shown in FIG. 4, the vibration plate 38 is formed using an angle material in a portion located above the belt 32, and therefore, when vibration is applied, the hydrophobic material or the like is not crushed and the hydrophobic material is not broken.

Thereafter, at the site where the hydrophobic material or the like is introduced, as shown in FIG. 1, the loaded hydrophobic material or the like is supplied to the supply port 28 of the hydrophobic material or the like introduction device 14 by tilting the loading platform 12 </ b> B with a hydraulic cylinder. It moves by the action of gravity. Then, as shown in FIG. 3, while applying vibration to the hydrophobic material or the like by the diaphragm 38, it is dropped from the supply port 28 onto the belt 32A of the belt conveyor 32, and sequentially transferred to the input portion 32C by the moving belt 32A. . Then, a hydrophobic material or the like is introduced from the input portion 32C into the excavation groove 50 in which the underdrain drain pipe 48 is embedded. At this time, the crawler type vehicle 12 can sequentially put an appropriate amount of a hydrophobic material or the like into the excavation groove 50 while moving along the excavation groove.

  As described above, according to the hydrophobic material charging device and the hydrophobic material charging vehicle of the present embodiment, the culvert drain pipe is buried with hydrophobic materials such as crushed stones, shells, gravel, sand, volcanic ash, etc. It is possible to efficiently put in the excavation groove.

  In the above-described embodiment, a prime mover (engine) is used as a drive source of the vibration mechanism. However, an electric motor or the like can be used as long as a certain output can be secured. Moreover, although this embodiment demonstrated the case where this apparatus was mainly used for the laying construction of a culvert drain pipe, for example, a sandbag bag is provided in the input part 32C of the belt conveyor 32, and gravel, sand, etc. are transferred. It is also possible to use this apparatus for the filling operation.

As described above, according to the present invention, a fixed amount of crushed stones, hydrophobic materials such as shells, gravel, topsoil, volcanic ash, etc. are put into the excavation trench in which the underdrainage pipe is buried as it is. It is possible to efficiently carry out the laying work of underdrain water pipes.
