  When the briquette is compressed and formed by the briquette machine 01, the fixed hopper 32 and the movable hopper 33 are fixed using bolts and nuts. More specifically, with the fixed side flat portion 55 in the fixed hopper 32 and the movable side flat portion 56 in the movable hopper 33 in contact with each other, the bolt and nut are passed through the fastening hole 71 and the fastening hole 72 to be fastened and fixed. As a result, the fixed hopper 32 and the movable hopper 33 are fixed.

  In the briquette machine 01, when the drive unit 15 is driven, the rotational driving force of the drive unit 15 is first transmitted to the first roll shaft 13. Since the first gear 29 provided on the first roll shaft 13 and the second gear 30 provided on the second roll shaft 14 are engaged, the rotational driving force of the first roll shaft 13 is the second roll. It is transmitted to the shaft 14 and rotates in opposite directions. Further, when the motor 23 with a speed reducer is driven in this state, the hollow shaft 23c in the motor 23 with the speed reducer rotates, and the fitting shaft 19c fitted to the hollow shaft 23c rotates, so that the feeder screw 19 is rotated. Rotates. The raw material in the hopper 18 is pushed between the first roll 11 and the second roll 12 from the feeder screw 19. And the pocket formed in each outer peripheral surface of the 1st roll 11 and the 2nd roll 12 cooperates, and a briquette is compression-formed by pressurizing and solidifying a raw material.

  When opening the hopper 18 such as when cleaning the inside of the hopper 18, it can be opened by the following procedure. First, the bolts and nuts fastened and fixed through the fastening holes 71 and 72 are removed. Next, the hand-held part 57 is pulled. The link mechanism 34 connects the fixed hopper portion 32 and the movable hopper portion 33, and the first arm 51 and the second arm 52 rotate as the hand holding portion 57 is pulled. Therefore, as shown in FIG. 1, the movable hopper 33 opens with respect to the fixed hopper 32.

  According to this briquette machine 01, the hopper 18 is formed by dividing the fixed hopper portion 32 and the movable hopper portion 33 along a surface along the longitudinal direction of the hopper, and the fixed hopper portion 32 and the movable hopper portion. Since 33 is fixed by the link mechanism 34 so as to be opened and closed, the hopper 18 can be easily opened to the fixed hopper portion 32 and the movable hopper portion 33 manually. Thereby, workability | operativity can be improved in the cleaning regarding the inside of the hopper 18, and the other work regarding the inside of the hopper 18.

  Further, by using the speed reducer-equipped motor 23 in which the functions of the motor and the speed reducer are integrated to drive the feeder screw 19, a shaft coupling required for connecting the motor and the speed reducer is not necessary. As a result, the number of parts can be reduced.

  Next, a modification of one embodiment of the present invention will be described.

  In the above embodiment, as shown in FIG. 1, the fixed-side extension portion 53 is provided on the left side of the fixed hopper portion 32, and the method of opening the movable hopper portion 33 with respect to the fixed hopper portion 32 is left-opening. However, the fixed side extending portion 53 may be provided on the right side of the fixed hopper portion 32 so that the movable hopper portion 33 is opened to the fixed hopper portion 32 to the right.

  In the above embodiment, a motor with a reduction gear integrated with an orthogonal shaft is used as the motor 23 with a reduction gear. However, the rotation shaft of the motor portion 23a and the hollow shaft 23c have a parallel shaft integrated reduction device. A motor may be used.
