Description

[Detailed explanation of the invention] (Industrial application field) This invention softens the tea leaf tissue while
This invention relates to a tea milling machine that evaporates water, and in particular to a cover for a spatula for kneading tea leaves.

(Prior art) There is a structure shown in FIG. 6 as a conventional technology.

That is, a metal band-shaped spatula 2 extending in the counter-rotation direction is connected to the tip of an arm 1 that rotates in the direction of arrow A, and a cover 3 made of an elongated cloth bag is attached to the spatula 2. 3 from the rear end 2b side.

A mouth string 4 is provided on the mouth portion 3a of the cover 3, and the mouth portion 3a is inserted up to the front end portion 2a of the spatula 2, and the mouth portion 3a is squeezed by the mouth string 4 at this portion, and the front end 2a is tightened.
Attach it to the periphery.

Then, a presser metal fitting 5 is attached to the outer surface side of the front end portion 2a of the spatula 2, and the presser metal fitting 5 is attached to the opening portion 3a of the cover 3.
There was a structure in which the opening 3a was abutted from the outer surface side of the spatula 2, and the opening 3a was fastened and fixed to the front end 2a of the spatula 2 with a bolt/nut 6.

(Problems to be Solved by the Invention) In the above-mentioned conventional device, the cover 3 was formed in a bag shape, so that, for example, as shown by the imaginary line in FIG.
If the spatula 2 has a bracket 2c for connecting the arm on the inner surface (back surface) of the rear end 2b, there is a drawback that the cover 3 cannot be attached.

In addition, since the cover 3 completely surrounds the inner surface (back surface) of the spatula 2, which is bag-shaped and does not press the tea leaves, the amount of materials required to manufacture the cover 3 increases, and the bending rigidity of the cover 3 increases. This has the drawback that the removal of the deposits adhering to the cover 3 is time-consuming.

The object of the present invention is to obtain a novel spatula cover that eliminates the above-mentioned drawbacks.

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention provides a flexible band-shaped cover that approximately corresponds to the outer surface area of the spatula on the outer surface of the spatula that faces the kneading bottom plate. The structure is such that it can be attached and detached.

(Function) Since the present invention has the above structure, the cover does not surround the inner surface (back surface) of the spatula.

Therefore, when attaching the cover to the spatula, it is not greatly influenced by the inner surface shape of the spatula.

Furthermore, since the cover is in the form of a band, it requires less manufacturing material and has lower rigidity and increased flexibility.

(Example) Hereinafter, an example of the present invention will be described based on the drawings.

First of all, in the drawings, Fig. 1 is a perspective view of a cover showing an embodiment of the present invention, Fig. 2 is a side view of the cover attached to a spatula, and Fig. 3 is a cross-section of a tea processing machine to which the present invention is applied. It is a diagram.

In FIG. 3, 10 is a machine frame, and the machine frame 1
Non-ventilated bottom plate 11 formed into a semi-cylindrical shape
and an air-impermeable case 12 formed in an inverted box shape that covers the upper part of the kneading bottom plate 11 are attached, thereby providing a rough kneading chamber 13 surrounded by the kneading bottom plate 11 and the case 12.

A hot air supply path 14 communicating with the rough kneading chamber 13 is provided on the right side of the case 12, and an input port 15 for supplying tea leaves and a work port 16 for inspection and maintenance are provided on the left side of the case 12, respectively.

A rotary shaft 17 is installed through the rough kneading chamber 13 located at the axial center of the kneading bottom plate 11.
arms 1 extending radially in opposite directions to each other;
8 and leaf zarai 19 are connected.

The arm 18 is connected to the rotation shaft 17 so as to be swingable in the counter-rotation direction (left rotation direction in FIG. 3),
A spatula 20 that runs along the kneading bottom plate 11 is connected to the tip (lower end) 18a of the arm 18.

The spatula 20 is formed by curving a thick, band-shaped sheet metal material into a corrugated shape, and its left end, that is, the front end 20a, is fixed to the tip 18a of the arm 18 by bolting.

A cover 21, which is a feature of the present invention, is removably attached to the spatula 20.

This cover 21 is designed as shown in FIG.

That is, the cover main body 22 is formed from a cloth material knitted into a belt shape to have approximately the same width and approximately the same length as the spatula 20.

The cover main body 22 has a locking fitting 23 bent in a U-shape with a sheet metal material facing rightward connected to the left end 22a, and a cloth band 24 is connected to the upper surface of the right end and the middle part in the longitudinal direction. , 25 to the cover body 22
The clasp 2 is arranged so as to extend in a direction perpendicular to the
6 and 27 to fix both.

The right end portion 22b of the cover main body 22 and one end portion (front end portion) 24a of the band 24 are both reversely bent upward, and the reversed portions of both are continuously overlapped with each other to form a pocket portion I.

Hooks 28a and 28b are provided on the upper surface of the overlapping portion and the upper surface of the other end of the band 24, and are removable from each other.
Install.

Additionally, hooks 29a and 29b which can be engaged with and detached from each other are attached to both ends of the band 25 in the intermediate portion.

Then, the cover 21 configured as described above
is attached to the spatula 20 as shown in FIG.

That is, the cover main body 22 is arranged on the outer surface of the spatula 20, that is, on the side facing the kneading bottom plate 11, the pocket part A is fitted and locked to the right end (counter-rotation side end) 20b of the spatula 20, and the locking fitting 23 is attached to the spatula 20. 20 (rotation side end) 20a.

Then, use a spatula 20 to attach the ends of each band 24, 25.
Each hook 28a, 28b,
By engaging 29a and 29b, the cover body 22 is attached to the outer surface of the spatula 20.

In addition, when removing the cover body 22 from the spatula 20, each hook 28a of each band 24, 25,
28b, 29a, 29b, and then the pocket part A is removed from the right end part 20b of the spatula 20.
Finally, the locking fitting 23 is removed from the left end portion 20a of the spatula 20.

As shown in FIGS. 4 and 5, the cover 21 according to the present invention has a large number of protrusions 30 made of plastic or rubber material on the outer surface of the cover body 22, that is, on the side facing the bottom plate 11. Good too.

In this way, by preparing a plurality of types of covers 21 having convex stripes of a predetermined shape and selecting the covers 21 as appropriate and attaching them to the spatula 20, rough kneading performance suitable for the type of tea leaves or the amount of tea leaves to be accommodated can be achieved. It can be obtained cheaply.

(Effect of the invention) As is clear from the above explanation, the present invention has a structure in which a flexible band-shaped cover approximately corresponding to the outer surface area of the spatula is removably provided on the outer surface of the spatula facing the kneading bottom plate. As a result, the cover no longer surrounds the inner surface (back surface) of the spatula.

Therefore, according to the present invention, the cover can be attached to the spatula without being greatly influenced by the inner shape of the spatula.

Moreover, since the cover is in the form of a band, it requires fewer manufacturing materials, making it cheaper, and it is less rigid and more flexible, making it easier to remove deposits such as tea juice and powdered tea leaves that have adhered to it due to use. This has the effect of making it easier.
