Description

  The present invention relates to a crusher, and more particularly, to a crusher for the purpose of efficiently crushing trash and the like made of a mixture having an irregular shape in a multistage manner and finally making it into extremely fine pieces.

    Conventionally, as a pre-treatment device such as a dust disposal machine, various cutters and the like have been developed and proposed as a means for quickly and reliably executing the treatment. It is ideal to crush up to.

  However, due to the nature of “garbage”, its shape, weight, etc. vary widely and is a mixture of unspecified shapes and weights, and it is particularly difficult to crush and crush it with feathers, paper and thin-skinned vegetables. It is a cut and mixing of a very light and large surface area such as.

  To date, no crusher has been provided that can simultaneously process a wide range of shapes, weights, hardnesses, and the like found in so-called general garbage (raw garbage).

  Japanese Patent Application Laid-Open No. 2002-28622 of Patent Document 1 separates a processing tank into upper and lower stages by a partition plate provided with an openable and closable communication port, and the upper stage is set as a fermentation chamber and the lower stage is set as a drying chamber, and is put into the fermentation chamber. The raw garbage was fermented by stirring with a stirring blade, and the fermented product was dried by opening the communication port.

  Japanese Patent Application Laid-Open No. 2004-298773 of Patent Document 2 has a rotating shaft that stands up from the center of the bottom floor plate of the processing tank and a plurality of fixed members that have a blade portion that extends radially outward from the rotating shaft and forms a main cutter. It is a garbage processing apparatus provided with a blade and an inclined plate for up-and-down stirring gradually inclined higher in the rotation direction.

    In any of the above-described conventional garbage processing machines, in any case, the raw garbage cannot be crushed while being sequentially cut and gradually broken into pieces, and it is an object of the present invention to solve this problem.

  A scavenging blade and a double rotary blade are fixed to a lower end portion of a screw shaft having a spiral blade vertically disposed in a main body case in which an upper hopper shape portion and a lower cylindrical shape portion are integrally formed, A fixed blade is fixed to the main body case, and it is configured to crush or crush trash or the like made of an indeterminate shape mixture while dropping downward as the screw shaft rotates, and is fixed to the motor holding base. The drive force of the motor is transmitted to the drive shaft through the shaft coupling, and the screw shaft is rotated through the gear as the drive shaft rotates. A process in which fixed blades are provided so as to be positioned between the spiral blades of the screw shaft on the inner side of the cylindrical portion, and the dust or the like made of an indefinite shape mixture falls below the main body case In Providing a crusher characterized by being configured so as to be crushed are sequentially finer debris reduction.

  According to the crusher of the present invention, since the garbage consisting of the irregular mixture is crushed in a multistage manner and crushed, it is configured to be fragmented into fine pieces. This makes it easier to post-process the garbage.

  Hereinafter, the crusher of this invention is demonstrated concretely based on drawing.

  In the drawings, FIG. 1 is an overall perspective view of the crusher of the present invention. FIG. 2 is an overall cross-sectional view of the crusher of the present invention. FIG. 3 is a front view of the screw. FIG. 4 is a plan view of the upper rotary blade. FIG. 5 is a front view of the upper rotary blade. FIG. 6 is a bottom view of the rotary blade. FIG. 7 is a front view of the rotary blade. FIG. 8 is a plan view of the upper fixed blade. FIG. 9 is a front view of the upper fixed blade. FIG. 10 is a plan view of the lower fixed blade. FIG. 11 is a front view of the lower fixed blade.

  As shown in FIG. 1, the entire configuration of the crusher of the present invention is such that the main body case 15 is integrally formed with an upper hopper shape portion 16 and a lower cylindrical shape portion 17, and the motor 1 is directly connected thereto. The torque of the motor 1 is set to 8 N-m or more, and the rotation speed is set to 150 rpm or more.

  A screw shaft 7 is rotatably disposed vertically in a body case 15 in which an upper hopper-shaped portion 16 and a lower cylindrical portion 17 are integrally formed. The screw shaft 7 is shown in FIG. As shown in FIG. 2, the sweeper blade 8 and the double rotary blades 9 and 13 are fixed to the lower end portion of the screw shaft 7 in a multistage manner.

  The driving force of the motor 1 fixed to the motor holding base 2 is transmitted to the driving shaft 6 through the shaft coupling portion 3, and the gear 5 is moved along with the rotation of the driving shaft 6 held by the bearing in the bearing case 4. It is comprised so that the screw shaft 7 may be rotated through.

  As shown in FIGS. 1 and 2, both ends of the drive shaft 6 are held by bearing bearings in the bearing case 4, and the screw shaft 7 can be rotated via the gear 5 at the center.

  As shown in FIG. 2, the fixed blades 10 and 14 are fixed doubly in the cylindrical portion 17 in the main body case 15, and the double rotary blade 9 and the rotary blade 13 and the fixed blades 10 and 14 are Are arranged in a sliding state correspondingly.

  As shown in FIGS. 8 to 9, the fixed blade 10 is integrally formed from the cross-shaped extension portion 101 to the outer peripheral portion 102 from the center, and by the screw portion 103 from the outside of the cylindrical portion 17 in the main body case 15. The extension portion 101 is formed with a plurality of holes 11.

  As shown in FIGS. 10 to 11, the fixed blade 18 is formed in a disc shape, and has a large number of holes 19, which are firmly fixed by the screw portion 20 from the outside of the cylindrical portion 17 in the main body case 15. It is fixed to.

  Due to the rotation of the screw shaft 7, the blades 71 cause the trash and the like made of the indefinite shape mixture introduced from the opening of the hopper-shaped portion 16 to be dragged downward. It is forcibly pulled downward.

  As shown in FIG. 2, a fixed blade 18 projects from the lower cylindrical portion 17 of the main body case 15 so as to be positioned between the screw blades 71 of the screw shaft 7. Large dust having a shape of 3 cm or more is cut to 1 cm or less by the fixed blade 18.

  The dust cut to 1 cm or less is pressed against the root of the rotary blade 9 by the sweeper blade 8 fixed to the screw shaft 7 by the boss 81. At this time, the dust of 1 cm or more that could not be cut is swept. Is repeatedly raised up and then dropped down and cut.

  As shown in FIG. 4, the shape of the sweeper blade 8 extends in four directions from the boss 81 fixed to the screw shaft 7, and is inclined as shown in FIG. 5. The above dust is once swung up, and the dust is further dropped down and cut.

  The dust pressed against the rotary blade 9 enters the cutting and crushing process with the fixed blade 10 and falls downward. The dust that has not been crushed falls again downward while repeating the above operation.

  The dust pressed against the lower rotary blade 13 is discharged again downward by repeating the cutting and crushing process again with the fixed blade 14.

  The upper rotary blade 9 and the lower rotary blade 13 have the same shape as shown in FIGS. 6 to 7, the center portion is fixed to the screw shaft 7, and the rotary blades 9 to 13 have a cutting edge portion. Curved and extended in all directions, the curved shape of the cutting edge makes it easier to cut dust.

  As described above, the crusher of the present invention configured to be broken into pieces and crushed sequentially in the process of falling dust or the like made of an indefinite shape mixture down to the main body case can be used industrially. It is a great thing.

  It is a whole perspective view of this invention crusher.   It is whole sectional drawing of this invention crusher.   It is a front view of a screw.   It is a top view of an upper stage rotary blade.   It is a front view of an upper stage rotary blade.   It is a bottom view of a rotary blade.   It is a front view of a rotary blade.   It is a top view of an upper stage fixed blade.   It is a front view of an upper stage fixed blade.   It is a top view of a lower stage fixed blade.   It is a front view of a lower stage fixed blade.
