Document Type and Number:
Japanese Patent JP6551951
Kind Code:
B2
Abstract:
Disclosed is a grain conveying apparatus using air, the apparatus efficiently collecting foreign materials while moving grains upward to a position at which the grains are easily fed into a grain processing machine by using the suction force air, and preventing shock so as to prevent damage to the grains. The grain conveying apparatus using air, according to the present invention, comprises: a grain supply hopper for accommodating the grains; a conveyer pipe for guiding the grains supplied from the grain supply hopper and the air flowing in from an external air inlet such that the grains, by means of the air suction force, and the air are moved together; a grain discharge pipe connected to the end of the conveyer pipe; a separation pipe for separating the grains and the foreign materials, the separation pipe comprising a horizontal part connected to the grain discharge pipe and a downwardly curved part for dropping the grains; a rotary valve connected to the lower part of the curved part of the separation pipe so as to discharge the grains in predetermined amounts; an exhaust pipe for discharging the separated foreign materials to the outside; and an air suction means having a ring blower connected to the end of the exhaust pipe so as to suck the air, wherein the front end of the grain discharge pipe is provided to penetrate the lower side of a finishing plate for closing a coupled part of the separation pipe, an inner diameter of the grain discharge pipe and an inner diameter of the separation pipe are formed to be small in a ratio of 0.4 to 0.5:1 such that the internal pressure of the separation pipe is lowered due to a change in the pressure difference, and a cut inclined surface, to be inclined in the direction of the grain conveyer pipe, is formed at the lower part of the front end of the grain discharge pipe, so as to cover the upper part thereof in order not to be influenced by the air discharged to the exhaust pipe connected to the upper side of the separation pipe, and allows the grains to be discharged to the lower side of the horizontal part of the separation pipe having a large inner diameter.
