Description

TECHNICAL FIELD The present invention relates to a crusher, and more particularly to a continuous crusher for crushing a crushed material into a crushed product in the process of continuously moving the crushed material.

[Prior Art] Conventionally, this type of continuous crusher has been disclosed in Japanese Patent Publication No. 58-35745. That is, the crushing roll of the roll crusher for impact crushing is installed on the upper part of the conveyor that moves in the horizontal direction, and the conveyor moves on the crushing plate and changes the direction and moves under the crushing plate in the opposite direction to move infinitely. Has been done. A double chain type scraper chain conveyor is used as the conveyor.

The crushed material conveyed by the conveyer conveyor is moved to the crushing roll, and is crushed by impact in the crushing gap formed between the crushing roll and the crushing plate to obtain a crushed product. It is discharged, moved, and again transferred to the transfer conveyor and transferred to the outside.

In the above roll crusher, when crushing a relatively coarse crushed material, by using a crushing roll having a large diameter,
It is crushed by increasing the above bite. When it is necessary to adjust the particle size of the crushed product, the crushing gap is adjusted.

[Problems to be Solved by the Invention] However, in the above-described conventional continuous crusher, when crushing a relatively coarse crushed material, unless a crushing roller having a large diameter is used, the crushed material is crushed between the crushed material and the crushing roller. Since the crushing roll cannot fully bite the crushed material by causing a slipping phenomenon, the crushing ability is significantly reduced. And
When using a crushing roll with a large diameter, there was a problem that the whole device was enlarged.

Further, in a roll crusher that performs impact crushing, members such as crushing rolls and a crushing table are greatly worn due to the wear associated with impact crushing, so that as a crushing material, the content of SiO ₂ is relatively low. There is a problem that it is limited to crushing soft material, and when adjusting the crushing gap to change the particle size of the crushed product as needed, the entire assembly including the crushing roll and the bearings on both sides, etc. There is a problem that it takes a lot of time for the adjustment work because it is necessary to move up and down to change the distance between the crusher and the crushing table.

The present invention solves such conventional problems,
With a compact structure, even a relatively coarse and hard crushed material can be crushed by compression to improve the crushing ability, and it is also easy to adjust the crushing gap. It is intended to provide a continuous crusher.

[Means for Solving the Problem] In order to achieve the above-mentioned object, the present invention compresses and crushes a crushed material between a crushing stand and a movable material to obtain a crushed product, and continuously crushes the crushed material and the crushed product. A continuous crusher equipped with a conveyor for moving on a crushing table, in which a frame is provided above the crushing table, a spindle is provided at one end of the movable material, and a bearing of the frame supports the bearing and the other end receives it. A main bearing provided with a seat and an upper part of the frame supports a main shaft having an eccentric part, and the eccentric part and the receiving seat are connected by a connecting material equipped with an adjusting material, and the movable material is used as a crushing table. On the other hand, with an inclined surface, the swinging motion is performed around the support shaft.

[Operation] The present invention having the above-described configuration has the following operations. That is, the crushed material that is moved in accordance with the movement of the conveyor is compressed and crushed between the movable material that performs an oscillating motion around the support shaft with the inclined surface and the crushing table that is fixed, and the crushed product becomes crushed products from the crushing gap. Since it is moved continuously according to the movement of the conveyor, it is possible to avoid using a crushing roll with a large diameter, it is possible to make the entire device a compact structure, and to use a movable material of an appropriate length. By
Even if the crushed material is proportionally coarse and hard, the crushed material can be compressed and crushed without increasing the height of the entire apparatus, and the crushing ability can be improved.

Furthermore, since the crushing gap can be adjusted only by using the adjusting material that is inserted into the connecting member that connects the eccentric portion and the receiving seat, the adjustment work for the crushing gap can be facilitated.

[Embodiment] FIG. 1 is a schematic explanatory view of a continuous crusher according to an embodiment of the present invention.

In FIG. 1, 1 is a continuous crusher, 2 is a movable material of the crusher 1, and 10 is a crushing table horizontally provided below the movable material. Reference numeral 3 denotes the frame of the crusher 1, which is provided above the crushing table 10 and has both side plates, which are connected in parallel by members. Reference numeral 11 denotes a main shaft, which is supported by a main bearing 9 provided on the upper portion of the frame 3, and an eccentric portion 12 is formed in the longitudinal direction of the main shaft 11. A support shaft 5 is provided at one end of the movable member 2, and a receiving seat 7 is provided at the back surface of the other end of the movable member 2. The support shaft 5 is supported by a bearing 6 provided on the frame 3, and the eccentric portion 12 and the seat 7 are connected by a connecting member 8. Further, the length of the connecting member 8 can be made variable by mounting the adjusting member 14 in the longitudinal direction of the connecting member 8.

In this way, the movable member 2 is disposed so that its surface has an inclined surface with respect to the crushing table 10, 15 is the inlet side of the crusher 1, and 16 is the outlet side of the crusher 1. In addition, W indicates the crushing gap of the crusher 1,
In this embodiment, the crushing table 1 on the outlet side 16 of the movable member 2
The distance from the upper surface of the crushed product is shown, and the particle size distribution of the crushed product is greatly affected.

To adjust the crushing gap W, for example, by adjusting the length of the adjusting material using a hydraulic cylinder or the like, the adjustment work can be facilitated only by changing the distance between the eccentric portion 12 and the seat 7. Is possible. Reference numeral 13 denotes a pulley attached to the main shaft 11, which is driven by a drive device (not shown), and the pulley 13 can also form a flywheel. Reference numeral 4 denotes a conveyor, for example, a double chain type scraper chain conveyor or the like is applied. The conveyor 4 is horizontally arranged on the upper part of the crushing table 10. The chain (both not shown) on both sides is rotated by a sprocket wheel, and the scraper is bolted in a direction perpendicular to the chain at a required interval. Installed by. The chains on both sides are guided by the grooves to move reliably, and in the upper part of the crushing table 10, they move in the direction of arrow A, that is, in the crushing gap near the outlet part 16, and move in the lower part of the crushing table 10. The direction is changed by the car and the endless movement is made in the direction of arrow B.

Next, the operation of the above embodiment will be described. In the above embodiment, the eccentric portion 12 rotates with the rotation of the main shaft 11,
A substantially vertical reciprocating motion is given to the connecting member 8, and an axial force acts on the receiving seat 7 to cause the movable member 2 to perform a swinging motion around the support shaft 5. When the conveyor 4 moves on the crushing table 10 in the direction of the arrow 4 and the crushed material is fed to the conveyor 4, the crushed material moves over the crushing table 10 while being scraped off by the scraper of the conveyor 4 and enters the entrance. Part 15 to crusher 1
Inside, and in the course of being moved in the direction of the crushing gap W, the crushed material is compressed and crushed by the oscillating motion of the movable material 2, and the particle size of the crushed material is successively reduced, and finally the crushing clearance W After passing through, the powder is converted into a crushed product having a particle size corresponding to the crushing gap W, discharged, and further conveyed by the conveyor 4 for a predetermined use.

[Effects of the Invention] As is apparent from the above-described embodiments, the present invention has the following effects.

The movable material has an inclined surface with a gap to the crushing table,
Since the swinging motion is performed around the support shaft, the entrance of the crusher is enlarged by using a movable material of an appropriate length, without increasing the height of the entire device including the frame. Even if it is a relatively coarse and hard crushed material, it can be crushed by compression and the crushing ability can be improved, and the wear of the member due to the rubbing wear due to the rotation like the conventional crushing roll can be improved. It is possible to reduce and economically crush.

Also, by adjusting the length of the adjusting material mounted in the longitudinal direction of the connecting material, it is possible to facilitate the work of adjusting the crushing gap.

Since the conveyor moves the upper part of the crushing table horizontally toward the crushing gap of the exit part, the crushed material and the crushed product are compressed and crushed on the movable material and the crushing table under a tensile force. By actively moving with, it is possible to prevent the occurrence of slippage and improve the crushing ability.
