Description

[Detailed explanation of the idea] The present invention relates to a pumping machine.

At the time of preparation in sake brewing, that is, the preparation water in the tank,
Once a certain amount of koji and steamed rice are added in that order, it is necessary to add the paddle. This is because the starch in the steamed rice is broken down by the enzymes (glucoamylase, acidic protease) of the koji into sugar (glucose), and the yeast produces alcohol and carbon dioxide gas from this glucose. If the contents are not homogenized by stirring, the alcoholic yeast will become weak, and there is a risk that the lactic acid bacteria will proliferate, resulting in an abnormal increase in lactic acid and spoilage (or rancidity).

By the way, in the past, the paddle filling process was done manually by holding a long paddle from the top of the tank.
It is very hard work and dangerous work. In addition, rice in recent years has been polished at a higher rate, and there is a risk of crushing the koji and steamed rice when paddled, resulting in a loss of quality.

The present invention aims to commercially offer a pumping machine that can be conveniently used in such cases, and the present invention device will be explained below based on the drawings.

Figure 1 is an overall perspective view, Figure 2 is a broken perspective view of the same,
FIG. 3 is a parts diagram of the cylindrical valve, and FIG. 4 is a partial detailed diagram of the main part.

Reference numeral 1 denotes a device frame in which piston means for performing suction and delivery operations, a valve case and driving means for the piston means are provided. That is, 2 and 2' are a pair of piston means, and pistons 2b and 2b' are provided so as to be moved up and down by driving means to be described later in piston tubes 2a and 2a', respectively, which are provided upright.

3 is a valve case with the piston cylinder 2a on the left and right,
2a' is erected, and a cylindrical valve 4 as shown in FIG. 3 is rotatably disposed in the central part of the cylinder body 4a. It is divided into a chamber 4d, and windows 5 and 5' with symmetrical directions on the left and right are bored in the circumferential surface of each chamber.

Reference numeral 6 denotes a hollow rotary shaft passing through the front chamber 4c, the front end of which is pivotally supported by a receiver tube to be described later, and the rear end penetrating the partition wall 4b and opening into the rear chamber 4d. The shaft 6 acts as a suction pipe during use as will be described later. Reference numeral 7 denotes a drive shaft provided at the center of the back surface of the rear chamber 4d, and a gear 8 is attached to the end of the shaft, so as to mesh with gears attached to the output shafts of the motor and reducer, which will be described later. It is.

Thus, the valve case 3 is divided into left and right chambers 9, 9' by the cylindrical valve 4 disposed at the center, and the windows 5, 5' are separated by the rotation of the cylindrical valve 4.
A front chamber 4c and a rear chamber 4d of the cylindrical valve 4 alternately communicate with a left chamber 9 and a right chamber 9' in the valve case 3 through the valve casing 3.

On the other hand, reference numeral 10 denotes a rotation shaft disposed at an upper position dividing the piston means 2, 2' into two, and 11, 11' denote horizontal levers integrally attached to the left and right sides of the shaft, each lever end is the piston means 2,
2' pistons 2b, 2b' and pins 12, 12' are freely fixed. Reference numeral 13 is another horizontal lever fixed to the rotating shaft 10, and the tip of the lever is connected to a crank arm of a driving means to be described below.

On the other hand, 14 is a motor fixedly installed outside the device frame;
Reference numeral 5 denotes the same reduction gear, and the rotation of the motor 14 is decelerated through the reduction gear 15 to rotate a gear 16 provided within the device frame.At this time, a crank arm 17 is attached to the gear 16. , the other end is attached to the horizontal lever 13, and as the gear 16 rotates, the horizontal lever 13, which is supported on the rotating shaft 10 via the crank arm 17, is swung up and down. horizontal lever 1
Pistons 1 and 11' are both swung up and down, causing the pistons 2b and 2b' to move up and down a certain distance, thereby operating the pump function. In addition, as the gear 16 rotates, the gear 8 meshed with the gear 16 rotates, and the cylindrical valve 4 is rotated within the valve case 3.

Reference numeral 18 denotes a receiving tube fixed to the front side of the device frame 1 of the valve casing 3 so as to cover the front chamber 4c with the front side of the cylindrical valve 4 which is rotated. Ring seat 19 serving as a bearing portion that supports the hollow rotating shaft 6
is formed, and a pipe port 20 that communicates with the hollow rotating shaft 6 is formed protrudingly on the outer surface so that a suction pipe is connected during use. A bent pipe 21 is provided to communicate with the inside of the pipe, and a discharge pipe is connected thereto during use. In addition, 22 is a stationary leg with a suction cup, 23 is a handle, and 24 is a power cord.

FIG. 5 is a usage state diagram, in which the suction machine with the above configuration is installed on the top of the brewing tank 25 in sake brewing, and the upper end of the suction pipe 26 raised from the bottom of the tank is connected to the pipe of the receiver pipe 18. A discharge pipe 27 is connected to the tip of the bent pipe 21 toward the inside of the tank.

Then, from above, a certain amount of brewing water, kojiro,
The steamed rice is added one after another, and when the addition is complete, the motor 14 is driven, and as the gear 16 rotates, the horizontal levers 11 and 11' swing via the crank arm 17, and the pistons 2b and 2b' move toward the piston cylinder 2a. ，
A vacuum is formed in the valve case 3 through the reciprocating operation in which the interior of the tank 2a' is alternately raised and lowered, and the rotation operation in which the cylindrical valve 4 is rotated via the gear 8, and the mortar at the bottom of the tank is transferred to the suction pipe. 26 into the rear chamber 4d, and distributed to the left and right chambers 9, 9' of the valve case 3 through the window 5' of the chamber 4d. The rice enters the chamber 4c and is discharged from the chamber 4c through the receiver pipe 18 and the bent pipe 21 and from the discharge pipe 27 to the upper part of the steamed rice in the tank.

According to the device of this invention, the koji and steamed rice can be pumped up together with the brewing water and sprayed from above without crushing them, making it possible to dispense with the conventional paddle work and greatly contribute to labor savings. It is. Additionally, since the koji and steamed rice are not crushed by the paddle, it also contributes to quality improvement.

In the above embodiment, a device used for pouring water during brewing in sake brewing has been described, but it can also be used for other purposes such as general water use and civil engineering work. An example of the specifications is a 90W electric motor, gear 15 rotation speed 50r, p, m, pipe diameter 1 inch, pumping head 4.5m, pumping capacity 20/min.

In the above explanation, the suction pipe 26 is connected to the pipe opening 2 of the receiver pipe 18.
0 and the discharge pipe 27 is connected to the curved pipe 21, but it is also possible to connect these relationships in the opposite manner. However, the above embodiment is superior in that no pumped material remains in the rear chamber 4d. Although not shown, cleaning ports may be provided in the left and right chambers 9, 9' of the valve case 3, respectively, to facilitate cleaning after use.
