SOLUTION: This stirring blade rotation transmitting device D is mounted on a filter B in one unit, and is reversed with a reversal supporting axis F as a supporting point. A stirring motor 1 is disposed on a supporting plate E in such a manner that it is isolated from a liquid tank A for the shift of the center of gravity to produce a decrease in reversing force load and the falling prevention of foreign matters, for rotating a stirring blade rotating shaft C via gears 2, 4, 5, 6 with chains 3. In order to prevent the contact of an extract with a machine, a water sealing chamber 8 is disposed on a side plate of the filter B, where a transmitting machine is stored. A washing water inlet (a) and a drainage (b) for permitting a residing water to drop in reversal are formed in U-shaped. The U-shaped portion is closed to produce a buoyancy.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a rotation transmitting device for a stirring blade of a strainer in an inverting extractor and a water sealing mechanism.

[0002]

2. Description of the Related Art A strainer (Ami basket) is put into a liquid tank filled with hot water.
, Soak the raw materials such as branches and leaves, stir and collect the extract. After the extraction is completed, in a device for inverting the filter and discarding the extraction waste outside the machine, filter the filter into the liquid tank and immerse the filter. As shown in FIG. 6, as a method of rotating the stirring blades in the strainer, the strainer having an inverting function is housed in a fixed position in the liquid tank, and the floating stirring shaft in the strainer and the liquid tank side The drive shaft must be engaged by a clutch mechanism attached to the vehicle and should be properly joined on a horizontal straight line. At this time, in the case of uncertain clutch engagement connection due to eccentricity of both,
As a result of clutch wear and slippage,
Strong stirring rotation cannot be obtained. In order to reliably match and set the floating stirring axis and the rotation axis, which are separated at different positions, on the same line, a high degree of precision and a complicated mechanism are required in manufacturing. Also, because the hygiene problem and the applied load are unknown,
A stirring blade rotation transmission mechanism has not been established due to difficulty in centering due to the separable eccentricity of the stirring shaft and the reversing shaft.

[0003]

A mechanism capable of reliably transmitting the rotation of the stirring blades of the reversing strainer, the structure of which the load does not overload the reversing force, and a transmission machine part for preventing food contamination and preventing foreign matter from being mixed. And the extract are not in contact with each other, and a mechanism capable of easily cleaning mechanical parts is obtained.

[0004]

Means for Solving the Problems A stirring blade rotating mechanism is mounted on a strainer, and is integrated and inverted. In addition, in order to move the center of gravity to reduce the reversing force load and to prevent dust and foreign matter such as mechanical oil from falling into the motor, the stirring motor should be installed near the reversing fulcrum shaft. Then, invert the entire strainer. The electric motor and the stirring shaft are transmitted remotely via a chain and gears.

[0005] In order to avoid contact between the extract and the rotation transmitting machine, a watertight chamber and a watertight shaft joint are provided on the side plate of the strainer. The water sealing chamber is U-shaped (ship bottom type) and automatically drains water by utilizing the natural fall due to the inclination angle at the time of inversion. In addition, an inlet for indoor cleaning and a drainage channel for discharge to the outside of the machine will be provided. Further, the reversal load force is reduced by utilizing the buoyancy of the ship-shaped watertight chamber.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a side view showing the whole mechanism of a reversing type extractor. A liquid receiving tank A, a strainer B, a stirring blade rotating shaft C, a stirring blade rotation transmitting device D, a support plate E, a reversing plate. 2, a filter shaft B, a reversing motor G, and a gantry H. Among them, the strainers B, C, D, E, and F are integrated, and as shown in FIG. The filter B is reversed by the reversing motor G with the fulcrum as a fulcrum, separated from the liquid receiving tank A, and the extraction waste is automatically discharged out of the apparatus by natural fall using the reversing angle.

The stirring blade rotation transmission device D is the device of the present invention, and the side view of FIG. 3 and the sectional view of FIG. 4 show the device attached to the side plate of the strainer B. In order to move the center of gravity and reduce the applied load, it is separated from the strainer B and placed on the support plate E connected to the reversing support shaft F. The rotation is performed by the gear 2 in the chain 3 and the guide gear 4 This mechanism transmits the rotation to the main shaft gear 6 below the liquid level, and rotates the stirring blade shaft C with the watertight shaft joint 7.

For the sake of food hygiene, a water sealing chamber 8 for preventing foreign matter from entering is provided on the side plate of the strainer B in order to isolate the extract from the mechanical parts. A washing water inlet a for indoor washing is provided at one of the ends at the upper position, and a drainage channel b extending to the outside of the machine is provided on the symmetrical inversion side so that the washing drainage accumulated in the water sealing chamber 8 or when a failure occurs. When water enters from the liquid tank side (water sealing shaft part), the drainage is discharged to the outside of the machine using the natural falling action by the reversal angle.

Further, a watertight shaft joint 7 is attached to the stirring blade rotating shaft C side of the watertight chamber 8 so as to prevent rotation of the shaft portion from being inundated, thereby preventing contact between the transmission machine and the extract. In addition, the watertight shaft joint 7 and the stirring blade rotating shaft C are detachably mounted with bolts 9.
Are linked by The chain cover 10 is attached for safety. An opening for inspection, cleaning and replacement of the spindle gear 6 is provided in the water sealing chamber 8, and a detachable sealing lid 11 is attached.

[0010]

DESCRIPTION OF THE PREFERRED EMBODIMENTS As described above, a method of incorporating each part of the stirring blade transmission mechanism of the present invention as a part of a strainer,
Further, in order to facilitate manufacture and assembling, a method in which the entire stirring blade transmission mechanism is attached to the strainer as an independent single unit as shown in FIG. 5 is possible.

[0011]

According to the present invention, the stirring blade rotation transmitting mechanism is mounted on and integrated with the strainer, so that the rotation of the blade can be reliably and smoothly transmitted. In addition, the load due to mounting the transmission mechanism on the strainer is reduced due to the movement of the center of gravity of the electric motor, which is a heavy object, to the reversing support shaft side and the buoyancy generated in the water sealing chamber. Since the agitating motor is arranged separately from the liquid tank and is remotely transmitted by the chain and the guide gear, it is possible to prevent foreign matter from falling into the liquid tank.

By providing the water sealing chamber, it is possible to prevent the stirring drive unit from coming into contact with the extraction liquid, and the washing water and foreign matters that have accumulated in the room during indoor cleaning fall naturally due to the inclination angle at the time of inversion. Can be automatically discharged to the outside of the machine through the drainage channel. Since the water surface when entering the water sealing chamber from the liquid receiving tank in an emergency is the same water surface at the highest because of the same natural pressure as the water surface of the liquid receiving tank, it is a structure that uses the principle that does not flow backward,
Contact between the transmission machine and the extract (product) is prevented.
