Description

  The present invention relates to a chip insertion vehicle, and more specifically, a chip for introducing a hydrophobic material chip, such as rice husk or wood chip, that forms a water permeable layer while the vehicle is running in a pipe laying groove in which a pipe for underground irrigation is laid. Regarding the input car.

  A culvert pipe is buried in the ground of the field to drain the field, and the groundwater level of the field is adjusted. Underground pipes are pierced by trenchers, and pipes that will become underground pipes are laid at the bottom of the pipe laying groove, and then have water permeability in the pipe laying groove, which adversely affects farming in the field. A predetermined amount of hydrophobic material chips such as rice husks and wood chips that do not reach is put in, and the hydrophobic material chips are covered and backfilled with excavated earth and sand. As a device for putting backfill material such as a hydrophobic material chip into a culvert or a side groove, a traveling vehicle main body, a cargo bed mounted on the traveling vehicle main body so that it can be raised and lowered with the rear end side as a rotation fulcrum, A conveyor mounted via a base mounted on the rear end side of the loading platform, for conveying the backfill material supplied from the loading platform in a direction transverse to the traveling direction of the traveling vehicle main body and dropping it into the groove 2. Description of the Related Art A backfill material charging vehicle including an apparatus is known (for example, see Patent Document 1).

Japanese Patent No. 3831767

  However, since the backfilling material input vehicle described in Patent Document 1 is provided with a conveyor device via a base body attached to the rear end side of the cargo bed, the conveyor device also rotates as the cargo bed rotates. Depending on the type of backfill material and the inclination angle of the conveyor device, it may not be possible to smoothly drop the backfill material from the cargo bed onto the conveyor device, or the backfill material cannot be transported reliably. May end up. For this reason, in the backfilling material input vehicle described in Patent Document 1, when charging relatively heavy volcanic gravel or gravel as a backfilling material, a belt conveyor is used as a conveyor device, which is lightweight and fluid. A screw conveyor is used as a conveyor device when throwing low rice husks or wood chips, but there is a big problem that the conveyor device must be properly used depending on the type of backfill material. Furthermore, the screw conveyor is more expensive than the belt conveyor, the charging speed is slower than that of the belt conveyor, and there are problems that rice husks and wood chips may be crushed in the screw conveyor.

  Therefore, the present invention aims to provide a chip insertion vehicle that can reliably insert even a chip such as a rice husk or wood chip, which is light in weight and poor in fluidity, into the groove.

  In order to achieve the above object, the chip insertion vehicle of the present invention is a chip insertion vehicle for introducing a chip into the pipe laying groove after laying a culvert tube at the bottom of the pipe laying groove excavated and formed in the field by a trencher. , A loading platform in which one end side in the traveling direction of the chassis equipped with the traveling means is turned as a rotation center, and the other end is rotated upward, a conveyor support provided in the width direction of the one end of the chassis, and supported by the conveyor support And a tip discharge port provided with a gate that opens and closes in the vertical direction by a cylinder. The belt conveyor is connected to the conveyor support base in the transport direction. It is characterized in that it is provided movably between a tip insertion position where the tip protrudes from the vehicle body and a storage position where the tip in the transport direction is stored within the width of the vehicle body

  Further, the chip insertion vehicle of the present invention is such that the traveling means is a rubber crawler, a camera capable of photographing the state of the chip discharged from the chip discharge port is provided at the top of the loading platform, and A driver's cab provided at the end protruding side of the belt conveyor at the end, a monitor for displaying images taken by the camera, and at least one end of the cargo bed in a funnel shape with a narrow lower part Forming and providing a generator mounting portion for mounting the engine generator on one lower surface portion of the loading platform formed in the funnel shape, and when the belt conveyor moves to the storage position on the other lower surface portion, A motor accommodating portion for accommodating a drive motor disposed at the upper end of the belt conveyor in the conveying direction is provided.

  According to the chip insertion vehicle of the present invention, the belt conveyor is supported by the conveyor support base provided at one end in the running direction of the chassis, for example, the rear end, so that the belt conveyor tilts even if the loading platform rotates. However, even a chip having a light weight and poor fluidity, such as a rice husk or a wood chip, can be reliably inserted into the groove while the chip insertion vehicle is running. Further, by using a rubber crawler as the traveling means, it is possible to reliably travel even on soft ground such as paddy fields, and by using a crawler wider than the groove width, the crawler does not fall into the groove. Further, by providing a camera for photographing the discharge state of the chip and providing a monitor on the cab, the chip can be dropped onto the belt conveyor while checking the state of the chip mounted on the loading platform. Moreover, space efficiency can be improved by forming the lower part of a loading platform in a funnel shape and providing a generator mounting part and a motor accommodating part.
