Further, the end side of the horizontal feed screw conveyor and the end side of the vertical feed screw conveyor are crossed so that their screw axes are orthogonal in a side view, and the conveying cylinder of the horizontal feed screw conveyor and the vertical feed screw conveyor are lifted. A means for arranging the grains in a connecting cylinder portion for connecting to the grain cylinders and transferring the grains at the crossing portion of the two screw conveyors of the horizontal feed and the vertical feed is actually developed.
It is known from JP 9274.

Further, in order to improve the grain-lifting ability at the crossing portion of the two screw conveyors of the horizontal feeding and the vertical feeding, a means for installing the grain feeding blades of the vertical feeding screw conveyor in a double spiral shape at the crossing portion is provided. , No. 52-75673.

[Problems to be Solved by the Invention] In the above-mentioned conventional means, in the first means shown in FIG. 1, the grains fed into the connecting tubular portion 4 by the lateral feed screw conveyor 2 are vertical. Connected so as to conduct the horizontal and vertical screw conveyors 2 and 3 when they are taken over by the lower end of the screw 31 of the feed screw conveyor 3 and are fed up into the fried food container 30 of the vertical feed screw conveyor 3. There is a problem in that the conduction mechanism provided in the tubular part interferes with the efficiency, resulting in poor fried performance.

In addition, the second means is that each of the two screw conveyors of the horizontal feed and the vertical feed has respective transfer paths for transferring the grains, which are adjacent to each other in plan view and side view. Since it is located at, there is a lot of loss in the delivery of grain and there is a problem that the efficiency of frying is poor. Furthermore, in order to change the discharge position of the grain from the discharge port at the tip of the discharge cylinder connected to the upper end side of the fried food cylinder that stores the vertical feed screw conveyor, the fried food cylinder is connected to the connecting cylinder part that stores the conduction mechanism. On the other hand, when it is rotated around the screw shaft center of the vertical feed screw conveyor, the reverse funnel-shaped guide surface provided on the inner surface of the connection port of the connecting cylinder portion with the frying cylinder makes the frying cylinder rotatable. Therefore, there is a problem that it is difficult to form a fitting portion for this.

The third means is the second method in which the above-mentioned grain transfer is poor.
In the above means, since the grain-feeding blade on the lower end side of the vertical feed screw conveyor has a double spiral, there is a problem that the grain-lifting performance is not improved.

The grains being sent into the connecting cylinder part by the horizontal feed screw conveyor while being conductively connected are smoothly inherited to the lower end part of the vertical feed screw conveyor and efficiently fed into the fried cylinder. In order to change the discharge position of the fried grain, the fried cylinder is freely rotated around the screw axis of the vertical shaft that can be stored in the fried cylinder with respect to the connecting cylinder part. In this case, a new means for preventing the reverse funnel-shaped guide surface provided at the connection port of the connection tubular portion from interfering with the formation of the fitting portion that allows the fried food barrel to rotate freely is provided. The purpose is to raise it.

The rotation of the fitting tubular portion 32 with respect to the connection tubular portion 4 enables the reverse funnel-shaped guide surface 32a to be performed without hindering the fitting portion for rotation.

Therefore, according to the means of the present invention, two screw conveyors 2 and 3 for lateral feeding and vertical feeding are firmly supported by the gear box 5 provided in the connecting cylinder portion 4 and the transmission mechanism 50 inside thereof. In addition, while connecting conductively by a simple transmission mechanism, the grains fed by the lateral feed screw conveyor belt 2 are connected to the large diameter of the upper surface of the gear box 5 in the connecting cylinder portion 4 narrowed by the gear box 5. The spiral blades 31b and 31d are double spirals at the lower end of the vertical feed screw 31 located in the wide space.
