In the conventional vertical shaft type grain milling machine, it is difficult to discharge the grains remaining in the grain feeding device or the grain milling room after milling is completed. In other words, it was necessary to remove the grain feeding device or the porous-walled bran removal cylinder and scrape out the remaining grains by hand, which was not only extremely troublesome but also had the problem of not being able to be completely removed. .

[Problems to be solved by the invention] This invention solves the above-mentioned problems, and makes it possible to easily and quickly discharge the grains remaining in the grain feeding device and the grain milling room at the end of milling. It is an object of the present invention to provide a residual grain discharge device for a vertical shaft type grain milling machine.

[Means for solving problems]

In order to achieve this purpose, this invention has the following configuration.

A screw trochanter and a grain milling trochanter are inserted into a vertical shaft rotatably provided in an upright porous-walled rice bran removal and polishing cylinder, and the porous-walled bran removal and polishing cylinder and grain milling trochanter are the main parts. One end of the grain milling room is connected to a grain supply section connected to a grain supply device, and the other end is connected to a grain discharge section to form a vertical shaft type grain milling machine. A rotatable grain discharge plate is provided at the bottom of the screw trochanter, and a residual grain discharge port with an on-off valve is provided at the lower side of the grain milling chamber. A suction machine that sucks up residual grains is connected via a transport pipe, and a blowing device that blows out residual grains in the grain feeding device is connected to the grain feeding device to remove residual grains from the vertical grain milling machine. Form a grain ejector.

[Effect]

The grains supplied from the grain supply section of the vertical grain milling machine to the screw trochanter are lifted by the screw trochanter, and the main parts are the porous-walled bran removal and polishing tube and the grain milling trochanter. The grain is milled in the milling room. The milled grains are discharged from the grain discharge section and sent to the next process. At the end of milling, the blowing device is operated to blow the remaining grains in the grain feeding device into the grain milling chamber. By communicating with the grain discharge port, the grains are sequentially discharged under the centrifugal force of the grain discharge plate. moreover,
The grains discharged from the residual grain discharge port are sucked through the transport pipe and discharged outside the machine.
