Description

[Detailed description of the invention] The present invention relates to a rocking device having a crushing function.

The rocking device for driving the slanted circular bottom plate of a container so that its center axis forms a conical shape is known in the art when the container is made of rubber. A patent application is pending as JP-A-52-26653.

These do not require fly pestle blades, and have various functions such as milling, mixing, polishing, and granulation due to the omnidirectional pivoting and lifting action of the container itself. In this invention, an annular blade is placed on the swinging bottom plate of the above-mentioned swinging device, and the material is compressed and crushed between the blade and the inner wall of the container.This is the first time that a swinging device has an active crushing function. is added.

The details will be explained below with reference to illustrated embodiments. 1st
, 2 show an embodiment of the present invention.

An inclined circular bottom plate 2 of a container 1 is driven by a motor 3 and an arm 4 so that its central axis A forms a conical shape. The frame 5 is used to rotate the container 1 around the support shaft 6 when taking out the material in the container 1, and the illustration of the base that receives the support shaft 6 is omitted. In this case, the upper part la of the container 1 is made of steel,
The lower part lb is made of rubber, and the bottom plate 2 is made of steel.

However, the bottom plate 2 means the circular rigid plate part at the bottom of the container 1,
It is not limited to the reinforcing disk as illustrated. What is added in this invention to the rocking device of this well-known structure is a blade shaft 7 that stands on the upper surface of the bottom plate 2, and when attached to the blade shaft 7, the outer circumference on the lower side is aligned with the inner wall of the container 1. There is only an annular vane, in this case an umbrella-shaped vane 8 in the shape of a head cone.

The lower outer circumferential portion 8a of the umbrella-shaped blade 8, which is inclined in accordance with the inclined bottom plate 2, is designed to create a gap B between the inner wall of the container 1 and the inner wall of the container 1 for compressing and pulverizing the lumpy and granular material during operation of the device. . In this embodiment, since the lower part lb of the container 1 is made of rubber,
When the oblique bottom plate 2 makes a unique swinging motion, the peripheral wall of the lower part lb of the container repeatedly deforms as shown in the cross section in the figure. That is, the peripheral wall of the container lb on the lower side (left side in the figure) of the inclined bottom plate 2 is elongated, and the lower part of the upper side (right side in the figure) peripheral wall is pried up, and the lower part of the lower side wall (on the right side in the figure) is pushed up. Lower outer periphery 8 of inclined umbrella-shaped blade 8
A always creates a gap B facing the extended circumferential wall of the container 1, so as the blade 8 swings, the position of the gap B is changed along the circumferential wall.
The grinding process progresses while moving. In this case, the material c in the container 1 is subjected to multidirectional swinging and jumping action, and when it comes near the peripheral wall of the container lb, when the peripheral wall stretches, it is reliably secured by the rotating umbrella blade outer peripheral part 8a. Compressed and crushed. Of course, since the peripheral wall is made of rubber in this case, the objects to be crushed are limited to relatively European materials. The conical outer circumferential surface of the umbrella-shaped blade 8 may be designed as appropriate depending on the object to be crushed, such as by making it more or less curved or having irregularities.

As the support member 9 on which the blade 8 is attached to the blade shaft 7, it is preferable to use a tube as shown in the illustrated example. The reason why the base 7a of the shaft 7 is thickened in a conical shape is to push the material outward from the vicinity of the center of the bottom plate 2, which is the dead center for the swinging motion, by its swinging motion. In this case, the blades 8 and shaft 7 are fixed to the bottom plate 2 and simply revolve, but it is also easy to extend the shaft 7 downward and attach a rotational drive device to it so that it rotates.
In that case, crushing teeth may be provided not only on the outer circumferential surface of the blade 8 but also at a corresponding position on the inner wall of the lower portion lb of the container, or a blade may be provided on the box base 7a to blow the material to the outer periphery. If the blade shaft 7 is made removable, such as by screwing it into the base 7a, the blades 8 can be replaced depending on the material to be processed.

If the container is made of Okayama body and the annular blade is placed at the zero position of the bottom plate, the shape will be similar to that of the rubber container shown in Figure 1.
It is unavoidable that the crushing force is weak because there is no deformation of the container peripheral wall. This invention has been found to have unique performance not only as a concrete mixer, but also as a retaining pestle for a wide range of powder particles, solutions, etc., and has added a new crushing function to a certain rocking device. This has made it possible to perform new rocking processes, such as directly and evenly mixing various materials with uneven particle sizes to a uniform particle size, and uniformly granulating adhesive materials. The slits for compressing and pulverizing the material are not in a fixed position and continue to move along the container wall at a high speed, so combined with the multi-directional movement of the material due to the multi-directional rocking and jumping action unique to the rocking device, the entire inside of the container is The material is quickly aligned below the slit size.
