【Example】

 An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows the overall structure of a crusher according to the present invention.

In FIG. 1, reference numeral 2 is a housing of the crusher 1, and an upper portion of the housing 2 is opened as a charging port 21. In the housing 2, as shown by the chain double-dashed line in FIG. 1, two screws 3 and 3 are arranged in parallel on the same horizontal plane. A motor 35 is connected to one end of each of the screws 3 and 3. The motor 35 causes the two screws 3 and 3 to feed the crushed material charged from the charging port 21 in a direction in which the crushed material is wound inward. It is configured to rotate in opposite directions. The bottom 22 of the housing 2 is provided with discharge ports 23, 23 for discharging the crushed material sent by the screws 3, 3.

The screw 3 is provided with a spiral blade 31 as shown in FIG. A plurality of guide members 32 are provided on the blade 31 at appropriate intervals so as to project in a direction substantially orthogonal to the blade 31, and the guide member 32 allows the blade 31 and the blade 31 to be crushed when crushing an object to be crushed. The object to be crushed entered between the blade 31 and the blade 31 is scraped out between the blades 31.

A distribution plate 4 is provided above the two screws 3 and 3. The distribution plate 4 has an upper end formed in a convex shape 41 so as to distribute the thrown crushed material to the respective screws 3 and 3, and both longitudinal ends thereof are fixed to the inner wall of the housing 2. .

The bottom of the distribution plate 4 is provided with an upper cutter 5 having fixed blades 51, 51 on both side edges in the longitudinal direction. The fixed blades 51, 51 of the upper cutter 5 are formed in an uneven shape in the longitudinal direction, and are arranged close to the blade 31 of each screw 3, and the fixed blades 51, 51 and the blades of each screw 3 are arranged. 31 and the object to be crushed passing here is crushed.

Further, on both side walls of the housing 2, side cutters 6 having fixed blades 61 at one side edge are arranged in the same direction as the axial directions of the screws 3 and 3. The fixed blade 61 of the side cutter 6 is formed in a concave-convex shape in the longitudinal direction, and is arranged close to the blade 31 of each screw 3, and the fixed blades 61, 61 and the blade 31 of each screw 3 together. The object to be crushed passing through here is crushed.

Further, in the center of the bottom portion 22 of the housing 2, as shown in FIGS. 1 and 3, a lower cutter 7 having fixed blades 71, 71 on both side edges is provided with a screw 3 via a mounting member 8. 3 is arranged in the same direction as the axial direction. The fixed blades 71, 71 of the lower cutter 7 are formed in an uneven shape in the longitudinal direction, and are arranged below the screws 3, 1 by the mounting member 8 and close to the blades 31 of the screws 3. The fixed blades 71 and 71 and the blade 31 of each screw 3 crush the object to be crushed passing therethrough.

The mounting member 8 arranges the lower cutter 7 at a predetermined position and prevents the crushed material from remaining at this portion (the center of the bottom portion 22).

As shown in FIGS. 3 and 4, a plurality of divided fixed blades 9 are provided on the bottom portion 22 of the housing 2 so as to be close to the blades 31 of the screws 3. In this example, the divided fixed blade 9 is divided into three in the rotation direction of the screw 3, and the divided three are arranged in three rows in the feed direction of the screw 3. The blade 31 of 3 crushes the object to be crushed passing therethrough. Note that the number of fixed fixing blades 9 and the arrangement positions thereof are not limited to this example.

Further, an inclined plate 25 is provided above the discharge port 23 to prevent the thrown object to be crushed from falling directly from the discharge port 23 without being crushed.

A side plate 26 is provided on the inner edge of the inclined plate 25. The lower edge of the side plate 26 is formed in an arc shape close to the outer periphery of the screw 3, and serves as a partition wall that partitions the upper space of the discharge port 23 from other spaces.

Next, the operation of the crusher configured as described above will be described.

The material to be crushed, which is input from the input port 21, is distributed by the distribution plate 4 to the left and right screws 3, 3. Since each screw 3 rotates in the direction in which the crushed object is wound inward, the crushed object is fixed between the fixed blades 51 and 51 of the upper cutter 5 and the blade 31 of the screw 3 between the screws 3 and 3. While being roughly crushed to the extent that it does not bite into, it enters between the screws 3 and 3, and is finely crushed between these screws 3 and 3. The material to be crushed between the screws 3 and 3 is sent in the feeding direction of each screw 3 and discharged from each discharge port 23.

At the time of crushing such a crushed object, the crushed object passing between the screws 3 and 3 is sent to the lower cutter 7 by the weight of the crushed object and the downward rotating force of each screw 3, It is further crushed by the fixed blades 71, 71 of the lower cutter 7 and the blade 31 of each screw 3.

Further, a part of the crushed material that has passed through the fixed blade 71 of the lower cutter 7 and the blade 31 of each screw 3 is a divided fixed blade in the middle of being sent to each discharge port 23 by each screw 3. Even when passing through 9, the divided fixed blade 9 and the blade 31 of each screw 3 are also crushed.

Further, the object to be crushed, which has been scooped up between the divided fixed blades 9 by the rotational force of each screw 3, is divided between the fixed blade 61 of the side cutter 6 and the blade 31 of each screw 3. Even during the break.

Here, when the crushed object is crushed by the crusher 1 described above, the crushed object that has entered between the blade 31 and the blade 31 of the screw 3 is guided by the guide member 32 to the blade 31 and the blade 31. It is scraped out from between and crushed as above.

Therefore, the crushed material that has entered between the blades 31 is not conveyed as it is to the discharge ports 23, 23 between the blades 31 and the crushed material is smoothly crushed. The size after crushing can be made substantially uniform.

In this example, the twin-screw type crusher equipped with two screws was described, but the crusher is not limited to the twin-screw type, and for example, a screw is further provided below the two screws. It can also be applied to a triaxial screw type crusher.

Further, in this example, a distribution plate 4 having an upper cutter 5 is provided between the screws 3 and 3, and the upper cutter 5 and the screws 3 and 3 coarsely crush the object to be crushed, and then the screws 3 , 3 is crushed more finely, but if it is desired to supply a large amount of crushed material between the screws 3 and 3, the distribution plate 4 may be removed together with the upper cutter 5. That is, the presence or absence of the distribution plate 4 provided with the upper cutter 5 may be determined in consideration of the properties of the material to be crushed.

The crusher 1 configured as described above is provided in the input portion of the waste storage device that is input through, for example, a chute, and the waste is crushed by the crusher and then stored in the waste storage device. And so on.

Further, since the size after crushing is substantially uniform, it is possible to collect smoothly when performing vacuum collection from the waste storage chamber to a waste collection vehicle or the like.

[0029]

[Effect of device]

 As described above, according to the crusher of the present invention, the blade of the screw is provided with a plurality of guide members protruding at a proper interval in a direction substantially orthogonal to the blade of the screw. The object to be crushed entered between the blade and the blade can be scraped out between the blade by the guide member. Therefore, the material to be crushed that has entered between the blades of the screw does not pass directly between the blades to the discharge port, and the material to be crushed is crushed smoothly, and the size after crushing is increased. Can be made substantially uniform.
