PURPOSE:To efficiently carry out the conveyance and discharge of a granular material, by constituting a granular material storing box with two left and right halves so that left and right frame members are rotated upward along with horizontal movement upon discharging of the granular material to discharge the latter into a conveyor device longitudinally arranged in the center. CONSTITUTION:When a granular material is conveyed, left and right frame members 9, 10 are abutted together by retracting left and right hydraulic cylinders 23 so that the space between flap doors 15 at each sides of the left and right frame members 9, 10 is coincided with the width of the front and rear walls 6. Thereby, the granular material is stored in a cargo box 8 and is conveyed in such a condition that the top of a screw conveyor 20 is closed. Then, when the granular material is discharged, the left and right hydraulic cylinders 23 are extended after a screw 19 in the screw conveyor 20 is rotated. Therefore, the right and left frame members 9, 10 are rotated upward about their shafts 16 after the left and right frame members 9, 10 horizontally move outward until their shafts 16 are made into contact with the outer ends of elongated grooves 17. Thereby, the granular material in the cargo box 8 is conveyed rearward by means of the screw 19 and then is discharged from a discharge port 21. |
