Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a grain conveying apparatus in which a transfer means having a spiral structure is rotatably mounted inside a cylindrical body. 2. Description of the Related Art In general, a cereal conveying apparatus of this kind has a flexible cylindrical body which is not deformed and has a cereal receiving / receiving port at one end and a cereal discharge casing having a lower end opened at the other end. The body was provided with a spirally wound transfer coil mounted rotatably inside, or a cylindrical body with a rigid structure, and a screw shaft with a screw transfer plate wound and fixed in a spiral shape was mounted inside. It is roughly divided into things. Further, there are a device that uses a power source of another device as a drive of the transfer coil and the screw shaft, and a device that has its own drive motor. [0003] For example, as shown in FIG. 1, a grain transported as described above is harvested with a combine and adjusted for threshing as shown in FIG. 1. Was transferred to a grain container mounted on the carrier of the carrier in the field, and then the carrier was brought back to the work, and the grain receiving and dispensing port provided at one end of the cylinder at the payout port of the grain container as shown in the figure. And the grains inside the grain container are fed into the receiving slot through the payout port by the screw transfer body of the grain container, and the grains are continuously shown in FIG. 3 from the lower opening of the discharge housing by the transfer means of the cylindrical body. Feeding and feeding to a hopper with transfer means at the bottom of the grain dryer,
Alternatively, it is supplied to a hopper provided with a transfer means at the lower bottom of the lower shown in FIG. 4, and the cereals are transported to other equipment. There is no problem because the supply of cereals to the hopper of the lower is supplied above the transfer means as shown in FIG. On the other hand, there is a case where grains harvested and threshed by a combine are packed in a bag and carried into a workplace, and the bags are sometimes manually input into a dryer hopper. Must be installed as low as possible. For this reason, the angle of the dryer hopper is formed loosely. Therefore, the speed at which the grains flow down on the wall of the hopper is slow due to the wetness of the grains fed into the hopper from the lower opening of the discharge housing, and a large difference is caused between the speed at which the grains are transported by the transfer means. Grains may gradually accumulate on the wall of the hopper, eventually closing the lower opening of the discharge housing and causing a clogging phenomenon. When this clogging phenomenon occurs, it becomes impossible to continuously pay out and transport the grains in the grain container. Therefore, as a safety measure, a sensor such as a limit switch is provided at a required position inside the discharge housing, and the sensor detects clogging. By the action, the driving of the screw transfer body of the grain container and the transfer means in the cylinder is temporarily stopped, and the accumulation of grains in the hopper is eliminated.However, depending on the properties of the grains, the frequency of such temporary stops frequently occurs, There is an inconvenience that the efficiency of a series of cereal processing operations is significantly impaired and the efficiency is reduced. [0004] It is an object of the present invention to provide a conveying apparatus capable of eliminating the accumulation of cereals in a hopper by simple means and enabling smooth feeding and supply of cereals. [0005] To solve the problems of the prior art, the structure of the present invention is to provide a cereal discharge housing having a cereal receiving opening at one end of a cylindrical body and a lower opening at the other end. In a grain transport device provided with a spirally structured transfer means rotatably mounted therein, an outer wall surface of the discharge housing which intersects with a grain transfer axis direction of the transfer means is opened and closed separately from the lower opening. It forms a possible grain outlet. [0007] Grains transported by the transfer means having a spiral structure mounted in the cylinder are dropped and supplied into the hopper from the lower opening formed in the discharge housing, and most of the grains are transported by the transfer means. Is transported outward through the discharge port provided on the outer wall surface of the discharge housing while the grains are held, and the grains are transported by the screw transfer member provided at the bottom of the hopper without being accumulated on the hopper wall surface. Next, an embodiment of the present invention will be described in detail with reference to the drawings. FIG. 1 is a side view showing an example of use of the apparatus of the present invention, and FIG.
