Conventional Technology For rough breaking of hard ores, rocks, limestone, etc., geocrushers are equipped with tooth plates or immovable teeth made of hard material such as manganese steel on the crushing surface, as shown in Figure 1. 1 and moving tooth 2 are attached.
In such conventional geocrushers, the crushing ratio is usually 4 to 5, and even special ones are 7 to 8, and the particle size of the crushed material is approximately 30 mm.
The following was the practical limit. Therefore, the inventors of the present application first set the crushing ratio to 10 or more and the particle size of the crushed material to 20 mm.
We have developed a tooth plate device for finely dividing a geo-crusher that can be In some cases, a supercharged state called "chiyoke feed" appeared and the particle size was reduced by chance, but it was impossible to always ensure that this state appeared, and in order to deal with this, we developed the system as shown in Figure 2. The crushing chamber 3 formed between the stationary teeth 1 and the movable teeth 2 of the tooth plate device for fine-splitting consists of a primary crushing zone A, a supercharging adjustment zone B, and a choke zone C, which are continuous in the direction in which the crushed material enters. In the supercharging adjustment zone B, the interval between the stationary tooth 1 and the movable tooth 2 is narrowed in the direction of movement of the crushed material, and the angle between the two teeth is set to 30.
It has been provided that the distance between the two teeth in the tooth yoke zone C is 0.5 to 1.5 times the longitudinal stroke of the movable tooth 2.

The operation of the above-described tooth plate device for finely dividing the geocrusher will be explained. The crushed material, which is a viscoelastic material produced by peeling off a pavement such as a road, flows in the direction of the arrow X into the crushing chamber 3 formed between the fixed tooth 1 and the movable tooth 2, as shown in FIG. Supplied. The movable tooth 2 moves as shown in FIG. 3 with respect to the stationary tooth 1. The supplied crushed material undergoes primary crushing in the primary crushing zone A of the crushing chamber 3, and then enters the supercharging adjustment zone B. Here, the supercharging adjustment is performed until the crushed material receives a compression action and an upward pushing action and enters the third slender choke zone C, and is secondary crushed in the next choke zone C. In such a crushing process, if the crushed material is a thin plate-like material, depending on the crushing state or the supply state of the crushed material, the plate-like material may reach the chiyork zone C as it is. The plate-shaped viscoelastic body is prevented from falling by the disk 5,
It is crushed and falls due to interaction with other crushed materials or crushed objects. At that time, the discharged crushed material is a viscoelastic material and may reach the cheese yoke zone C, but the plate-shaped viscoelastic material is prevented from falling by the disk 5, and other crushed materials are prevented from falling. Alternatively, it will be crushed and fall due to interaction with crushed objects. At this time, the discharged crushed material tends to stagnate at the lower end of the chuck zone C because it is a viscoelastic body, but as the disk 5 rotates, the stagnated crushed material is actively discharged downward. Therefore, the crushing ratio is 10
As described above, the crushing efficiency is maintained so that the particle size of the crushed material is 20 mm or less, regardless of the spacing of the chiyoke zone C, even if it is a plate-like viscoelastic body that has peeled off from a thin pavement, and the discharge is also smooth. It will be done.

Effects of the invention As described above, according to the invention of the present application, in the tooth plate device for finely dividing a geocrusher used for crushing a viscoelastic body such as a peeled pavement, A plurality of plate bodies such as disks are rotatably supported near the bottom of the discharge part of the viscoelastic body, and the plate bodies such as disks are arranged at intervals in the tooth width direction. , even plate-shaped viscoelastic materials whose thickness is thinner than the interval between the chiyoke zones C, which had previously fallen without being crushed, will not fall without being crushed, and the discharge end of the chiyoke zone C will no longer be crushed. Since the part is a viscoelastic material, it is possible to smoothly discharge the crushed material that tends to get stuck, and it is possible to achieve crushing efficiency with a crushing ratio of 10 or more and a crushing particle size of 20 mm or less, which greatly improves work efficiency. This has the excellent effect of providing a good fine-splitting tooth plate device.
