Description

[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crushing apparatus for crushing tea leaves, medicinal plants and the like into a required size.

[0002]

2. Description of the Related Art Generally, for processing finely powdered tea leaves for widely used tay packs and rough processing of powdered matcha, a mesh body having a required mesh size is reciprocally moved. Put the tea leaf to be processed on top, hold the tea leaf with a long presser bar, cut the tea leaf with the upper edge of the net body and the lower edge of the presser bar, and drop the shredded pieces under the net body The method of collecting by collecting is adopted.

According to the above-mentioned conventional processing means, in order to make a powder material of the final size, it is necessary to exchange the mesh many times to gradually reduce the mesh size to reduce the size. Since there are many steps until the powder is processed and the net body is replaced, it is inefficient and there is a problem that mass production is not possible.

[0004]

DISCLOSURE OF THE INVENTION The present invention solves the above problems of the conventional means and provides a crushing apparatus having mass-processability.

[0005]

The crushing apparatus of the present invention which solves the above technical problems is described as follows: "The outer periphery has a mesh cylinder circumference to which a mesh body of a required mesh is detachably mounted, and the center axis of the cylinder is the center. As a horizontal cylindrical support independently rotatably, and a screen portion of a hollow cylindrical body having one end as a fixed bottom, and a band-shaped cutting blade is arranged along the inner circumference of the cylinder of the screen portion,
Also, it consists of a cutting blade part that is concentrically rotatable with the screen part and a work supply part that is connected to the opening window of the fixed bottom. It has a structure with a cover ".

[0006]

In the crushing apparatus having the above-described structure, the screen portion of the mesh outer peripheral cylindrical body in which the mesh body of the required mesh is detachably mounted is rotated independently, and is also rotatable along the inner circumference of the circumference of the screen portion. Since the arranged cutting blades rotate concentrically with the screen part, the pulverized material supplied from the work supply part to the inside of the screen part is moved to the inner circumference of the screen part by centrifugal force of the rotating screen part. It is pressed and cut as it is on the cutting blade that rotates concentrically,
It is sandwiched between the inner circumference of the screen and the cutting blade, and cut and crushed extremely quickly and efficiently. Then, the pulverized product is immediately discharged to the outside through the mesh due to the centrifugal force generated by the rotation of the screen portion, and the pulverized product having a required size can be collected. Therefore, if the mesh of the screen portion is selected in advance to have an appropriate size, a required crushed product can be processed in a single pass from a normal form of tea leaves or the like by one crushing process.

[0007]

Embodiments will be described in detail below based on embodiments. 1 to 4 showing an embodiment of the present invention, a crushing apparatus according to the present invention has a screen portion 1 of a hollow cylindrical body having a cylindrical outer circumference and a fixed bottom 18 at one end. , Having a cutting blade 14 of a band-like blade arranged along the inner circumference of the screen portion 1 while being supported rotatably independently about a central axis 13 arranged at the axis of its own cylindrical body Axis 13
The cutting blade portion 2 that rotates integrally with the opening blade 20 of the fixed bottom 18
Has a work supply part 3 connected to the inside of the screen part 1, and the tea leaves or the like of the workpiece supplied from the work supply part 3 to the inside of the screen part 1 are cut and crushed by a cutting blade 14 to obtain the outer periphery of the screen part 1 of a required mesh. It is structured such that centrifugal force is discharged to the outside through the through and the crushed tea leaves and the like are stored and collected in the work basket 4 provided below.

Specifically, as shown in FIG. 4, the screen portion 1 has a skeleton formed by a cylindrical bone body 7 in which end rings 5A5B at the left and right ends are connected by ribs 6, and a mesh body 8 is formed on the circumference thereof. It has a hollow cylindrical body with a mesh circumference that is detachably attached. Then, the net body 8 forms an open cylindrical net which can be wound around the cylindrical bone body 7, and the opening portion is closed by a stopper 9 provided at the edge of the opening portion so that it can be detachably attached to the outer periphery of the cylindrical bone body 7. It is installed and set. The mesh bodies 8 are prepared in advance in various mesh sizes, and necessary ones are selectively used.

That is, the screen portion 1 has a closed bottom 1 which is integrated with the end ring 5B on the end ring 5B side at one end.
A fixed bottom 18 fixed to a frame 19 is inserted on the side of the end ring 5A at the other end, which forms a hollow cylinder having partition wall bottoms at both ends. A shaft hole 11 is provided at the center of the closed bottom 10, and the central shaft 13 of FIG. 1 is inserted through the shaft hole 11 so as to be rotatably supported relative to the central shaft 13.
The end ring 5B has a belt wheel 12 integrally and is belted and has an automatic rotation mechanism that is rotated by an independent drive unit 23, and the other end ring 5A is attached to the frame 19 of the processing apparatus. Bearing roller 24 provided
The outer periphery is supported by the screen portion 1, and the screen portion 1 rotates in a direction indicated by an arrow B, which is opposite to the rotation direction of the cutting blade portion 2 described later.

On the other hand, as for the cutting blade portion 2, referring to FIGS. 2 and 3, a band-shaped cutting blade 14 having a cutting edge 15 at the front is attached to the tip of an arm 16 radially extending from the central shaft 13, and the cutting blade is cut. 14 are arranged side by side so as to be in contact with the inner side of the screen portion 1, and can interlock with the central shaft 13 to rotate in the direction of the arrow A shown in the figure with the cutting edge 15 as the traveling direction. The cutting blade portion 2 of this embodiment is a four-piece set in which the cutting blades 14 are arranged at four positions on the inner circumference of the screen portion 1, and the individual cutting blades 14 are intended to improve the cutting performance. , The center axis 17 of the central shaft 13
It is an oblique arrangement having a slight inclination angle θ with respect to the (axis center of the screen portion 1).

Then, a loading hopper 21, a screw conveyor 22 for connecting the opening window 20 and the loading hopper 21 is provided in the opening window 20 of the fixed bottom 18, and a work supply for loading a material to be crushed by the loading hopper 21 and the screw conveyor 22. It constitutes part 3. A scattering prevention cover 26 that prevents the work discharged from the screen portion 1 from scattering is covered on the outside of the screen portion 1 except below.

When the material to be crushed such as tea leaves is charged into the charging hopper 21, the tea leaves and the like are charged from the opening window 20 into the hollow portion of the screen portion 1 via the screw conveyor 22 and rotate independently in the opposite direction. It is shredded and crushed by the cutting blade 14, and the crushed product is discharged to the outside through the mesh of the screen portion 1 by the rotating centrifugal force of the screen portion 1 and is collected in the work basket 4. The rotation speed of the screen portion 1 in this embodiment is about 60 rotations per minute, and the rotation speed of the cutting blade portion 2 is about 1,000 rotations per minute. Further, in this embodiment, since the cutting blade 14 is provided with the above-described inclination angle θ, the tea leaves and the like in the screen portion 1 tend to be biased toward the end ring 5B side due to the influence thereof.
