The present invention relates to a residual grain discharge device for discharging grains remaining in a grain lifting cylinder that is set upright to lift grains.

(b) Conventional technology Conventionally, in this type of grain lifting machine, for example,
As shown in Publication No. 55-102947, the tip of the grain-lifting cylinder is branched into two stages, one of which is used for the next process, and the other is opened to the outside, and a switching valve is provided at the branched part to allow the next process to proceed. supply and take it out to the outside.

However, with such a configuration, it is impossible to remove even the grains that remain in the machine at the end of the operation, and they end up accumulating at the bottom.

Therefore, a separate cleaning opening with a shutter was provided near the bottom to remove the grains that had accumulated at the bottom.

(c) Problems to be solved by the invention As described above, in the case of conventional grain frying machines, a separate cleaning opening was provided to take out the residual grains that had accumulated at the bottom of the machine. In addition to being a nuisance, it has become a nuisance that must be taken out from the outlet.

Therefore, the present invention provides a residual particle discharging device which has a simple structure and can easily discharge residual particles, as an improved version of the conventional device.

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

That is, in a grain lifting cylinder in which a screw conveyor is rotatably installed, a grain intake port is opened on one side of the lower end, and a grain discharge port is opened on the upper end, and the grains are lifted up. A state in which the grain lifting cylinders are individually rotatable around the shaft of the screw conveyor, and the intake port is aligned with the supply gutter for grains to be fried, so that the grains flow into the grain lifting cylinder and are lifted up. By rotating the grain lifting cylinder, the supply gutter is closed, and at the same time, the intake port is directed to the outside and the grains in the grain lifting cylinder are discharged. It also serves as a grain outlet.

(E) Effect Since the present invention is constructed as described above,
If the intake port is aligned with the supply gutter, the grains to be fried will flow from the supply gutter through the intake port into the grain frying cylinder, will be lifted up by the rotation of the screw conveyor, and will be taken out from the discharge port at the upper end. Now, when the work is finished, if only the grain lifting tube is rotated, the other side with no open intake becomes the shutter, and the supply gutter is closed, and the intake is opened to the outside. The intake port becomes the discharge port, and the grains remaining at the bottom are discharged to the outside by the rotation of the screw conveyor.
