As shown in FIGS. 3 and 4, two exhaust pipes 14 are provided at an intermediate portion of the planes 5 c ₂ and 5 c ₄ facing each other along a line L 2 that divides the intermediate chute 5 into two in the longitudinal direction. Yes. As shown in FIG. 6B, the discharge pipe 14 is a pipe that opens to the inner surface 5d of the intermediate chute 5 and extends to the outside through the outer wall 5c. The air introduced between the inner surfaces 5d is discharged to the outside.

Since the present invention is configured as described above, its operation will be described below.
It is assumed that raw materials such as rubble containing mud are dropped in the direction of arrow C on the conveyor 1 and pulverized by the pulverizer 2. In this state, as shown in FIG. 1, it is assumed that the mud stays in an annular shape around the entire inner surface of the intermediate chute 5 and an annular mass M of mud is formed. That is, the mass M is attached to the entire outer surface of the rubber sheet 8, 9 on the inner surface 5 d of the intermediate chute 5.

  At this time, the tip of the suction hose 11 of the air tank 12 is connected to all of the eight introduction pipes 10, and high-pressure air is supplied from the air tank 12 to the eight introduction pipes 10 through the suction pipes 11. In the intermediate chute 5, it sprays instantaneously all at once.

  Then, high-pressure air is instantaneously injected from the eight introduction pipes 10 into the gap t between the inner surface 5d of the intermediate chute 5 and the inner surfaces 8 ′ and 9 ′ of the rubber sheets 8 and 9. As shown in FIGS. 6A and 11, the rubber sheets 8 and 9 are elastically bulged toward the inner surface side of the intermediate chute 5 due to the pressure of high-pressure air (FIGS. 6A and 11A). ) (See (b) two-dot chain rubber sheet 8, 9).

  The rubber sheets 8 and 9 are laid on the entire inner surface 5d of the intermediate chute 5, and only the outer peripheral edge (peripheral edge) is connected in an airtight or substantially airtight manner. The rubber sheets 8 and 9 bulge in an annular shape over the circumferential direction of the inner surface 5d of the intermediate chute 5. become.

  Accordingly, as a result, the mud lump M adhering to the inner surface 5d of the intermediate chute 5 (that is, the outer surfaces of the rubber sheets 8 and 9) is rubbed out due to the momentary swelling of the rubber sheets 8 and 9. It can detach | leave from the 8th and 9th surface, can drop the lump M over the inner surface 5d perimeter, and can remove adhesion of a raw material.

  The high-pressure air introduced into the inner surface 5d of the intermediate chute 5 is immediately discharged from the discharge port 14 to the outside of the intermediate chute 5. At the same time, the rubber sheets 8 and 9 return to the original state due to the elastic restoring force.

Of course, if the attachment position of the raw material is, for example, only in the vicinity of the arc surface 5c ₄ ′ of the intermediate chute 5, the suction hose 11 is connected only to the two introduction pipes 10 corresponding to the arc surface 5c ₄ ′. The other introduction pipes 10 are closed with screw caps, and high-pressure air can be injected only into the two introduction pipes 10. In this case as well, the injected air is discharged to the outside from the discharge port 14 of the rubber sheet 8.

  In this case, since only the rubber sheet 8 in the portion where the high-pressure air is introduced bulges inward, the adhesion of the raw material only at that position can be removed. In this way, it may be configured such that the place where the raw material adheres (resides) is identified and high-pressure air is injected only into the introduction pipe 10 close to that position.

  As described above, according to the present invention, when a raw material such as rubble containing mud adheres to the inner surface 5d of the intermediate chute 5, high-pressure air from the air tank 12 is introduced via the suction hose 11 into the introduction pipe 10. Since the rubber sheet 8, 9 (rubber sheet 8 and / or 9) can bulge inward due to its elasticity, it is attached to the inner surface 5d side of the intermediate chute 5. Deposits such as mud can be easily removed.

  Moreover, according to the position of the deposit | attachment adhering in the intermediate | middle chute | shoot 5, high pressure air is injected to any one introduction pipe 10 near the position of the deposit | attachment, or several inlet pipe 10, and an deposit | attachment is removed. The deposits can be removed efficiently.

  Further, the deposit removing device can be compactly arranged around the intermediate chute 5 including the air tank 12, and the deposit can be efficiently removed without requiring a large-scale device.

  Further, the suction hose 11 is connected to all the introduction pipes 10 in advance, and it is only necessary to inject high-pressure air from the air tank 12 corresponding to the introduction pipe 10 in accordance with the position of the deposits. Can be removed.

  The deposit removing device according to the present invention is provided in a chute in front of the crushing device, so that the raw material can be smoothly charged into the crushing device and is expected to be widely used.
