Abstract

(57) [Summary] [PROBLEMS] To provide a screw feeding member for reducing clogging of crushed pieces in a crushed piece feeding device of a type that feeds with a screw feeder having a screw pitch shortened at a discharge port. [Structure] In a crushed piece feeding device using a screw feeder in which a screw 2 is disposed in a cylindrical hopper 3 and a screw pitch on the discharge side is shortened, an outer periphery of the screw 2 and an inner wall of the hopper 3 are provided on a wall surface of the hopper near the discharge port. A crushed piece feeding device provided with a rod-shaped body 6 projecting into the clearance between and so that the projecting length can be adjusted. The rod-shaped body 6 may be a high tension bolt, and a plurality of the rod-shaped bodies 6 may be provided in the longitudinal direction of the hopper 3. When the screw 2 is rotated, the crushed pieces at the tip of the screw are caught by the rod-shaped body 6, and due to the inclination pitch of the screw 2, the force of F ₁ for rotating the crushed pieces and the force for pushing the crushed pieces up F ₂ The clogging is removed by the resultant force F of.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a crushed piece feeding device using a screw feeder, and more particularly to a crushed piece clogging prevention device in a screw feeder in which a screw pitch is shortened at a discharge port.

[0002]

[Prior art]

In the field of crushers for paper, construction waste, etc., a crushed piece feeder is provided to send the crushed pieces that have been crushed to about 1 cm ² in pretreatment and sent by air for compression packing. Conventionally, in the crushed piece feeder using a screw feeder, when sending crushed pieces, there are many types in which the screw pitch is the same, but in order to give the screw feeder a compression function for crushed pieces, the discharge port of the screw feeder It may be possible to shorten the screen pitch on the side.

[0003]

[Problems to be solved by the device]

 However, when the screw feeder is provided with a compression function, there is a drawback that the clogging of debris increases in the screw portion where the screw pitch is shortened. In particular, when the clearance between the screw and the hopper bar is reduced, the clogging of the crushed pieces is increased, and the crushed pieces are not fed.

The problem to be solved by the present invention is to provide a screw feeding member for reducing clogging of crushed pieces in a crushed piece feeding device of a type that feeds by a screw feeder having a screw pitch shortened at a discharge port.

[0005]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the crushed piece feeder of the present invention is a crushed piece feeder using a screw feeder in which a screw is arranged in a cylindrical hopper and the screw pitch on the outlet side is shortened. A rod-shaped body protruding into the clearance between the outer circumference of the screw and the inner wall of the hopper is provided on the wall surface of the hopper so that the protruding length can be adjusted. A high tension bolt can be used for the rod-shaped body. Further, a plurality of rod-shaped bodies can be provided in the longitudinal direction of the hopper.

[0006]

[Action]

 The present invention focuses on the fact that in a screw feeder with a short screw pitch on the outlet side, compressed crushed pieces slip on the inner wall surface of the hopper, rotate together with the screw, and are not conveyed by some screws. However, a rod-shaped body that forms a protrusion is provided in the clearance between the screw and the hopper so that the crushed pieces do not rotate integrally with the screw while slipping on the inner wall surface of the hopper.

FIG. 2 shows a mechanism for removing clogging of a crushed piece screw feeding member of the present invention. 2, the force of F ₁ that get back to the original jam, resultant force F of the force F ₂ to try to do the above plugging, blockage is removed.

The rod-shaped body can be configured by an inexpensive adjusting mechanism called a high-tensile bolt / nut. In addition, a plurality of rods can be provided on the inner wall surface of the hopper to improve the efficiency of removing clogging.

If the crushed piece feeding member of the present invention is used, clogging of the crushed pieces can be reduced, and by utilizing the compression function inherent in the screw feeder, the crushed pieces can be compressed and sent.

【Example】

 Hereinafter, the present invention will be described in detail based on examples. FIG. 1 is an enlarged view of a main part of a crushing piece feeding device to which the crushing piece screw feeding member of the present invention is applied. In FIG. 1, a high-tension bolt 6 and a nut 7 for adjusting the clearance between the screw 2 and the hopper 3 of the crushed piece feeder 1 are provided on the hopper 3 and the clearance is adjusted to obtain the optimum discharge clearance. .

FIG. 3 is an overall view of the present invention. In FIG. 3, the crushed pieces crushed by the crushing device 8 pass through the crushing piece feeding duct 9 and are sent by the motor 5 of the crushing piece feeding device 1 to the rotating screw 2 via the shaft 4. The crushed pieces are compressed in the lower part of the screw 2, and at this time, they pass through the clearance adjusted by the high-tensile bolt 6 and the nut 7, so that they are discharged without jamming the paper.

[0012]

[Effect of device]

 As described above, the present invention provides the screw feeder for adjusting the clearance between the screw and the hopper in the screw feeder in which the screw pitch is shortened at the discharge port. Therefore, according to the present invention, the crushed pieces can be sent without causing clogging, while the crushed pieces have a compression function, and the crushed pieces can be compressed and discharged, which simplifies post-treatment and reduces costs.
