"Prior Art" In the conventional vertical grain sorter 1, the feed hopper 2 for supplying unsorted grain is close to the base of the fried helix 3 and surrounds it as shown in FIG. It opened directly into the grain cylinder 4.

At the end of the sorting step, a residual grain discharge pipe 5 for discharging the grains remaining at the bottom of the grain receiving cylinder 4 and a discharge gate 6 at the bottom of the grain receiving cylinder 4 were provided.

"Problems to be Solved by the Invention" However, in such a conventional vertical grain sorter 1, since the unsorted grain fed from the feed hopper 2 is directly fed to the fried helix 3, The unsorted grain to be fed into the grain receiving cylinder 4 and the grain to be scraped up by the spiral blade 5 of the fried helix 3 compete violently in the opening 2a of the supply hopper 2. , Smooth feeding was hindered.

When the number of grains supplied to the supply hopper 2 falls below a certain amount, the grains that are about to enter the grain receiving cylinder 4 from the opening 2a and the grains that are splashed by the fried helix 3 are balanced. When the operation is stopped due to the virtually stopped supply of grains, the grains remaining in the vicinity of the opening 2a enter into the receiving cylinder 4 and become a large amount of residual grains, and the discharge gate 6 It was difficult to eliminate all the residual kernels even when opening the.

The present invention has been made by paying attention to such a conventional problem, and surrounds the base of the fried helix, and by providing an appropriate unselected grain guiding means, a smooth grain is provided. Not only is it possible to feed the particles, but even if the amount of feed from the supply hopper is small, all can be fed into the grain receiving cylinder, and after the supply from the supply hopper is exhausted It is an object of the present invention to provide a vertical grain sorter capable of effectively eliminating the remaining grains and preventing the small grains falling from the outer periphery of the sorting net from remaining or clogging below the sorting grains.

"Means for Solving the Problem" The gist of the present invention for achieving such an object is to provide an external body equipped with a supply hopper for supplying unsorted grains and a storage tank for storing refined grains. Inside the shell, a vertical axis for selecting grains by accommodating a fried helix in which spiral blades are wound around the outer periphery of a cylinder and a sorting net body in which the fried helix is concentrically inserted and rotatably held relative to each other. In a type grain sorter, the base of the fried helix spiral is provided so as to surround it, and the upper end opening has a cylindrical peripheral edge surface following a horizontal peripheral edge that opens outward, and from the supply hopper. With a grain receiving cylinder that receives unsorted grains and supplies the grain to the fried helix, and is provided between the grain receiving cylinder and the base of the fried helix,

The upper outer periphery is provided with a partition disk that is slidably contacted on the horizontal peripheral portion of the grain receiving cylinder and the outer periphery approaches the inner periphery of the peripheral surface of the grain receiving cylinder to discharge the small grains out of the machine, The lower part of the grain guiding cylinder facing the frustoconical taper part formed in the lower part of the grain receiving cylinder is located below the lower edge of the tip opening of the supply hopper and the grain guiding cylinder. A plurality of grain guide ports that open to the lower end of the grain guide port are provided, and grain guide blades that start downward near the upper edge line of each grain guide port and turn downward when rotating are provided on the outer peripheral surface of the grain guide cylinder, respectively. It exists in a vertical grain sorter characterized by being configured.

"Operation" The unsorted grain is fed to the feed hopper, and the vertical grain sorter is started.

The unsorted grain fed from the supply hopper is placed in the grain receiving cylinder provided at the base of the fried helix by the grain guiding blade of the grain derivative of approximately the same diameter that rotates in the same direction as the sorting net. The grain is fed downward, and the grains are fed from the plurality of grain guiding ports provided on the lower peripheral surface of the grain guiding cylinder to the starting end of the fried helix that rotates in the direction opposite to the sorting net body. It

The grain scraped up by the fried helix is subjected to a sorting action by the sorting net while being splashed outward, the small grain passes through the sorting net and is eliminated, and the eliminated small grain is The good grains that do not pass through the sorting net body rise as they are and are stored in the storage tank as they fall onto the partition disk and remain there or are not clogged and are effectively removed from the machine.

The unsorted grains fed from the supply hopper are pushed down by the grain guide blades and introduced from the grain guide port, so that the grains to be scraped up by the spiral blades of the fried helix and the feed hoppers. The supplied grains do not interfere with each other and are smoothly fed, increasing the amount of fed grains.

Even if the sorting work is almost completed and the amount of grains supplied from the supply hopper is decreasing, the opening in the grain receiving cylinder of the supply hopper is opened at a position higher than the grain induction port,
