Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a tea processing machine that evaporates water while softening the leaf tissue of tea leaves. This relates to a scraping tool for scraping.

(Prior art) As a conventional technology, there is a structure shown in FIG. 3.

That is, a semi-cylindrical rolling bottom plate 2 is fixed to the machine frame 1, and the upper part of the rolling bottom plate 2 is covered with a sheet metal cover 3.
to form a rough kneading chamber 4.

The above-mentioned rolling bottom plate 2 is formed by fixing an inner plate 2b made of bamboo material to the inner surface of an outer plate 2a made of sheet metal.

A hot air supply port 5 for discharging hot air into the rough kneading chamber 4 is formed in the upper right part of the rough kneading chamber 4, and a charging lid 6 for introducing tea leaves is attached to the upper left part of the rough kneading chamber 4 so as to be openable and closable. A discharge lid 7 for discharging tea leaves is attached to the lower part of the rolling bottom plate 2 so as to be openable and closable.

In addition, a prismatic rotating shaft 8 is arranged in the rough kneading chamber 4 located at the axial center of the kneading bottom plate 2, and its both ends are suspended over the machine frame 2, and one end thereof is connected to a motor (not shown). do.

A fork-shaped leaflet 9 and a V-shaped bent arm 10 are attached to the rotating shaft 8 so as to protrude outward in the radial direction. This arm 10 has its bent portion supported swingably by a pin 12 on a bracket 11 attached to a rotating shaft 8, and is supported by a spring 1.
3, the swinging end 10a of the arm 10 is pressed against the bottom plate 2.
Pressure is applied so as to approach the target.

A plate metal spatula 14 is attached to the swinging end 10a of the arm 10. This spatula 14 is bent into an L-shape, its base is fixed to the swinging end 10a of the arm 10, and its main body 14a is extended in the counter-rotational direction of the rotating shaft 8, and is curved in a wave-like manner to form a kneading bottom plate. 2
It is arranged close to the inner surface of.

Then, tea leaves are put into the rough kneading chamber 4, and while supplying hot air into the rough kneading chamber 4 from the hot air supply port 5, the spatula 14 is turned to the right in FIG. The spatula 14 presses the tea leaves in the roughening chamber 4 against the crushing bottom plate 2 while stirring them, thereby roughly crushing the tea leaves.

Further, when the rough rolling is completed, the tea leaves in the rough rolling chamber 4 are discharged to the outside by opening the discharge lid 7 while swinging the spatula 14.

(Problem to be solved by the invention) In the above-mentioned conventional device, the spatula 14 is rotated while maintaining a predetermined gap with the inner surface of the rubbing bottom plate 2, so when discharging the tea leaves to the outside, A small amount of tea leaves attached or deposited on the inner surface of the bottom plate does not come into contact with the spatula 14 and stays inside.
For this reason, the operator has to manually discharge the accumulated tea leaves, which is time consuming and dangerous.

In addition, the above-mentioned manual discharge tends to be incomplete, and there is a drawback that some of the tea leaves are mixed into the new tea leaves input in the next process, resulting in a decrease in quality.

The object of the present invention is to obtain a novel scraper for a tea milling machine that eliminates the above-mentioned drawbacks by completely discharging the tea leaves in the roughening chamber to the outside while rotating the spatula during the discharge process.

(Means for Solving the Problems) In order to achieve the above object, the present invention is constructed as follows.

That is, a rotating shaft is provided at the axial center of the kneading bottom plate formed in a semi-cylindrical shape, an arm protruding radially outward is provided on the rotating shaft, and a spatula facing the inner surface of the kneading bottom plate is provided at the tip of the arm. In the tea manufacturing and rough rolling machine, a scraping tool made of a soft elastic body is provided at the end on the opposite rotation side of the spatula, and the tip of the scraping tool is bent in the direction of the rolling bottom plate.

(Function) Since the present invention has the above-mentioned configuration, when the rotating shaft is rotated, the spatula and the scraper rotate along the kneading bottom plate via the arm. If there is a large amount of tea leaves in the coarse rolling machine,
The tip of the scraping tool is elastically deformed backward in the direction of extension of the spatula by the tea leaves interposed between the spatula and the rolling bottom plate, and when the amount of tea leaves in the rough rolling machine becomes small, the tip of the scraping tool is It will elastically return in the direction of the bottom plate.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

In the drawings, FIG. 1 is a sectional view of a main part showing an embodiment of the present invention, and FIG. 2 is a perspective view of a main part of the scraping tool.

In Figure 1, 2 is the kneading bottom plate, 4 is the rough kneading chamber, and 8
is a rotating shaft, and these have a similar structure to that shown in FIG.

15 is an arm attached to the rotating shaft 8;
This arm 15 has its base rotatably supported by a pin 17 on a bracket 16 fixed to the rotating shaft 8, and its swinging end 15a is bent in the counter-rotational direction of the rotating shaft 8. Moving end part 15
A is pressed so that it approaches the rubbing bottom plate 2.

A band-shaped spatula 19 made of a sheet metal material is attached to the swinging end 15a of the arm 15. This spatula 19 is curved in a wavy manner in the longitudinal direction, and its base 19a and tip 19b are connected to both ends of the swinging end 15a in the rotating direction by pins 20 and 21, so that it can approach the inner surface of the kneading bottom plate 2. Deploy.

A plate-shaped scraper 22 made of a soft elastic material such as rubber is attached to the opposite end of the spatula 19, that is, the right end 19c in FIG.

That is, as shown in FIG. 2, the left end of the scraping tool 22 is placed on the back (top) of the right end 19c of the spatula 19, and the metal holding plate 23 bent into a hook shape is placed on the top of the left end. The right end portion 22a of the scraping tool 22 is fixed to the right end portion 19c using the machine screw 24, and the right end portion 22a of the scraping tool 22 is secured to the hook portion 23a of the holding plate 23.
The bottom plate is bent in two directions.

The amount of protrusion of the tip 22a of the scraping tool 22 is such that the tip of the spatula 19 comes into contact with the inner surface of the scraping bottom plate 2 when the spatula 19 is under no load.

Next, the operation mode of the above embodiment will be explained.
When the rotating shaft 8 is rotated, the spatula 19 and scraping tool 22 are rotated along the kneading bottom plate 2 via the arm 15.

In this case, during the rough rolling process when a large amount of tea leaves are present in the rough rolling chamber 4, the spatula 19 is largely separated from the rolling bottom plate 2, and the scraping tool 22 has its tip 22a between the spatula 19 and the rolling bottom plate 2. The tea leaves interposed between them cause the spatula 19 to be elastically deformed backward (to the right) in the extension direction of the spatula 19 and separated from the kneading bottom plate 2, as shown by the imaginary line in FIG. The rubbing is done smoothly.

Next, during the discharge process of discharging the tea leaves in the rough rolling chamber 4, if there are a large amount of tea leaves in the rough rolling chamber 4, the tea leaves are mainly transferred by the spatula 19 toward the discharge port and are transported to the outside. When the amount of tea leaves in the rough kneading chamber 4 becomes small, the tip 22a of the scraping tool 22 elastically returns in the direction of the kneading bottom plate 2, and the tea leaves are mainly transported by the tip 22a toward the outlet and exit outside. It will be discharged.

Then, when the tea leaves in the rough rolling chamber 4 are almost gone,
As shown by the solid line in FIG. 1, the tip 22a of the scraper 22 comes into contact with the inner surface of the scraping bottom plate 2. As a result, a small amount of tea leaves adhering to the inner surface of the rough kneading chamber 4 is scraped off by the tip 22a and discharged to the outside.

(Effects of the invention) As is clear from the above explanation, the invention provides a scraping tool made of a soft elastic material at the opposite end of the spatula, and the tip thereof is bent in the direction of the scraping bottom plate. Therefore, in the discharge process, all the tea leaves in the roughening chamber can be discharged to the outside while rotating the spatula without degrading the rough-milling function of the spatula.

Therefore, the present invention has the effect of safely and reliably discharging the tea leaves in the roughening chamber and preventing deterioration of the quality of the tea leaves in the next process.
