The cab 36 is provided.

  The belt conveyor 34 conveys the hydrophobic material chip 17 discharged from the chip discharge port 35 toward the hopper 18, and a belt 34b is disposed inside the support member 34a. A conveyor support base 32c provided at the tip of the frame 32b is slidably supported in the vehicle body width direction. Further, belt driving means 34c such as a hydraulic motor is provided at the upper end of the support member 34a.

  And between the 1st traveling body 12 which pulls the pipe laying machine 11, and the 2nd traveling body 32 of the chip loading machine 31, the relative traveling position of both the traveling bodies 12 and 32 is shown in the belt conveyor 34. A travel position holding member 41 that holds the tip in a state of being positioned above the hopper 18 is provided. The travel position holding member 41 shown in the present embodiment includes an attachment member 42 provided at the lower end in the traveling direction of the frame 32 b of the second traveling body 32, and a base end attached to the attachment member 42. Are provided at the lower end of the front end of a support member 45 that protrudes laterally from the rear end portion of the first traveling body 12. The cylindrical receiving member 46 is formed.

  The cylindrical receiving member 46 has a bottomed rectangular tube shape having a rear opening 46a into which the tip of the spacing member 44 can be inserted, and is formed in a quadrangular frustum shape that expands from the bottom toward the rear opening 46a. Has been. The length and the width direction position of the spacing member 44 are set so that the hydrophobic material chip 17 can be dropped into the hopper 18 from the front end of the belt 34b.

  When laying a culvert pipe on a field using the culvert pipe laying device formed in this way, a pipe connected to the rear portion of the first traveling body 12 via a link mechanism 21 in a state of being irradiated with a reference laser beam. The laying machine 11 is placed at a preset construction start point, and the pipe laying machine 11 is inserted into the ground to a predetermined depth while the first traveling body 12 is slightly advanced. In addition, the tip insertion device 31 is positioned on the left rear side of the first traveling body 12, and the tip of the interval holding member 44 protruding forward from the frame 32 b of the second traveling body 32 is disposed on the first traveling body 12. The position of the chip loading machine 31 is adjusted so that the cylindrical receiving member 46 is inserted into the cylindrical receiving member 46 from the rear opening 46a disposed on the left side.

  Then, the first traveling body 12 is advanced at a predetermined speed, and the pipe laying groove 13 of the pipe laying machine 11 is cut and formed by the pipe laying groove forming portion 14, while the pipe 15 unwound from the reel 24 is moved by the pipe guide portion 16. The pipe 15 is guided along the bottom of the pipe laying groove 13, and the pipe 15 is laid along the bottom surface of the pipe laying groove 13.

  At the same time, the chip feeder 31 operates the belt conveyor 34 to appropriately raise the rear part of the loading platform 33 and raises the gate 35a to drop an appropriate amount of the hydrophobic material chip 17 from the chip discharge port 35 onto the belt conveyor 34. In this state, the second traveling body 32 is advanced so as to keep the state where the tip of the spacing member 44 is inserted into the cylindrical receiving member 46. Thereby, the hydrophobic material chip 17 is supplied into the hopper 18 of the pipe laying machine 11 by the belt conveyor 34, and the hydrophobic material chip 17 in the hopper 18 is loaded into the pipe laying groove 13 from the chip insertion port 26. At this time, the height of the hydrophobic material chip 17 in the pipe laying groove 13 is positioned by the hydrophobic material chip insertion height adjusting member 19, and the hydrophobic material chip 17 is inserted into the pipe laying groove 13 at a constant height. It becomes a state.

  During the construction, it is only necessary to perform the driving operation of the second traveling body 32 so that the tip of the interval holding member 44 does not come off from the inside of the cylindrical receiving member 46, and it is only necessary to advance in a straight line. It can be carried out. In addition, it is necessary to check the state of the hydrophobic material chip 17 in the hopper 18 and operate the loading platform 33 and the gate 35a, but since the difference in the chip supply amount from the belt conveyor 34 can be absorbed by the hopper 18, Compared with the case where the hydrophobic material chip 17 is directly put into the pipe laying groove 13, the operation is easy.

  Moreover, since the right side wall 18b of the hopper 18 is formed high, not only can the strength of the hopper 18 be improved, but even if the supply amount of the hydrophobic material chips 17 from the belt conveyor 34 increases, the hopper 18 may overflow. Even if it overflows from the hopper 18, if the hydrophobic material chip 17 is a rice husk or a wood chip, it does not adversely affect the cultivation in the field.

  Further, since the stirrer 25 is provided inside the hopper 18, it is possible to reliably prevent the hydrophobic material chip 17 from forming a bridge and causing a drop failure, so that the hydrophobicity from the hopper 18 into the pipe laying groove 13 can be prevented. The material chip 17 can be reliably charged.

  Further, both ends of the interval holding member 44 can be connected to both the traveling bodies 12 and 32. However, by forming the traveling position holding member 41 with a configuration as shown in this embodiment, The direction change etc. can be performed separately with the 2nd traveling body 32, and workability | operativity can be improved. In addition, the manufacturing cost is low, the first traveling body 12 and the second traveling body 32 need not be remodeled, and the spacing member 44 can be easily attached and detached.
