Description

[Detailed explanation of the invention] <Industrial field of application> This invention softens the tissue of tea leaves while
The present invention relates to a tea processing machine that evaporates water, and particularly to a spatula device that rubs tea leaves.

<Prior Art> Generally, a tea processing machine and a spatula used therein have a configuration shown in FIG. 2.

That is, an air-permeable kneading bottom plate 2 made of bamboo material and woven into a semi-cylindrical shape is provided in the upper part of the box-shaped machine frame 1, thereby forming a rough kneading chamber 3 in the upper part of the machine frame 1.

A hot air supply section 4 is provided at the upper rear side of the roughening chamber 3, and an inlet 5 for supplying tea leaves and an outlet 6 for taking out tea leaves are provided on the top plate and lower part of the front wall of the front side of the roughening chamber 3. are provided respectively.

A rough kneading chamber 3 located at the axial center of the kneading bottom plate 2
A prismatic rotating shaft 7 is installed inside, and a leaf scraper 8 and a spatula 9 are attached to the rotating shaft 7.

The spatula 9 is formed by bending a thick sheet metal material into a wave shape, and its base end 9a, that is, the end in the direction in which the rotating shaft 7 rotates, is connected to the lower end of the L-shaped swinging arm 10. Connector 11 consisting of bolts and nuts is attached to 10a.
Connect removably. and swing arm 1
No. 0 had a structure in which the bent portion 10b was supported by a pin at the tip of a support arm 12 protrudingly fixed to the rotating shaft 7, and the upper end portion 10c was connected to the support arm 12 by a spring 13.

The tea manufacturing and rough rolling machine configured as described above supplies tea leaves from the input port 5 and hot air from the hot air supply section 4 into the rough rolling chamber 3, and grinds the leaves through the rotary shaft 7 into the leaf rougher 8 and the spatula 9. is rotated to the right as shown by arrow A, thereby steaming the tea leaves in the roughening chamber 3, while repeating the pressing of the tea leaves against the rolling bottom plate 2 by the spatula 9 and the stirring of the tea leaves by the leaf scraper 8. The tea leaves are roughly crushed to a predetermined thickness.

By the way, during the above-mentioned rough rolling operation, a part of the roughly rolled tea leaves will adhere to the spatula 9. If the adhered tea leaves are left as they are, the amount of adhered tea leaves will gradually increase, and when it reaches a predetermined value, it will be peeled off from the spatula 9, form a lump, and mix into the tea leaves in the rough kneading chamber 3.

This may reduce the roughening performance of the roughening machine, or the previous tea leaves may be mixed into the next tea leaves, impairing the quality.

For this reason, conventionally, the spatula 9 has been removed periodically to remove the tea leaves attached to the spatula 9.

However, since the spatula 9 requires strength, it is necessary to form it from a thick plate material and to attach it firmly to the swing arm 10.

For this reason, the work of removing the spatula 9 has the drawback of requiring labor and time.

<Problems to be solved by the present invention> The present invention makes it possible to easily remove deposits attached to the spatula by removably attaching a cover made of a flexible woven material to the outer surface of the spatula. The purpose is to ensure that

<Means for Solving the Problems> In order to achieve the above object, the present invention is characterized by the following configuration.

The kneading bottom plate formed in a semi-cylindrical shape has a rotating shaft at its center, an arm extending radially outward from the rotating shaft, and a spatula facing the inner surface of the kneading bottom plate at the tip of the arm. In the tea processing machine, the outer surface of the spatula facing the rolling bottom plate has a proximal end and a distal end made of a thin sheet metal material, and an intermediate part thereof made of a flexible woven fabric material. It is characterized by a structure in which the cover is removably attached.

<Function> Since the present invention has the above structure, the deposits generated by the rough rubbing action of the spatula adhere to the outer surface of the cover.

Therefore, by removing the cover from the spatula, the deposits can be substantially removed from the spatula. On the other hand, since the cover is made of a flexible woven material, it is light in weight and can be repeatedly bent to quickly remove deposits. Furthermore, since the load applied to the cover during rough kneading is borne by the spatula, the structure for attaching the cover to the spatula can be simplified.

Therefore, the cover can be easily removed.

<Example> Hereinafter, an example in which the above configuration is embodied will be described based on the drawings. A cover 19 according to the present invention,
An exploded perspective view of the spatula device 14 to which this is attached is shown in FIG.

Reference numeral 15 denotes a spatula connected to the swinging arm 10 by bolts and nuts (not shown), and the spatula 15 is used to hold a thick sheet metal material with both the front and rear ends facing downward in the longitudinal direction, that is, the second spatula.
In the figure, it is formed in a wavy shape so that it is convex towards the side of the kneading bottom plate 2 and the middle part in the longitudinal direction is convex upward.

The spatula 15 has a front or proximal end 15.
Weld and fix the mounting bracket 16 to a, and
is removably connected to the tip of the swing arm 10 described above with bolts and nuts.

Further, the spatula 15 has a hook-shaped engaging claw 17 protruding and fixed on the outer surface side of its base end 15a, and a bolt insertion hole 18 is formed in its tip end 15b. The cover 19 has a base end 19a and a distal end 19b made of a thin sheet metal material, and an intermediate part 19c made of a flexible woven fabric material.

The rear end 19d of the base end 19a and the distal end 1
The rear end 19e of the intermediate part 19c is bent upward, and the front and rear ends of the intermediate part 19c are folded into this part, and the two are integrally connected by a rivet 23.
An engagement hole 20 is provided at the base end 19a, and an engagement hole 20 is provided at the distal end 19a.
A bolt 21 is fixed upright on the inner surface of b. Then, the cover 19 is attached to the spatula 15 by engaging the engagement hole 20 with the engagement claw 17, inserting the bolt 21 into the bolt insertion hole 18, and screwing the wing nut 22 together.

According to the embodiment described above, the deposits on the spatula device 14 are attached to the cover 19.

When removing the deposits, remove the cover 19 from the spatula 15 by loosening the wing nuts 22 and removing them from the bolts 21, and then repeatedly bending the intermediate portion 19c of the cover 19 to remove the deposits. Remove.

The cover 19 from which the deposits have been removed is attached to the spatula 15 in the same manner as described above.

Here, since the cover 19 can be obtained at low cost, it is easy to prepare spare parts in advance. In this case, by replacing the cover 19 with the deposits attached with a spare cover, the downtime of the roughing machine can be further shortened.

<Effects of the invention> As explained above, according to the structure of the present invention,
By removing the cover, which is light in weight, can be bent repeatedly, and can be easily attached to the spatula, it is possible to easily and quickly remove deposits attached to the spatula device.
