Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a drying chamber (or grain tank) in which grains to be dried are placed, which is formed in a polygonal or cylindrical shape, and in which the grains placed in the drying chamber are Drying of the grains is carried out by drying air blown up from below the floorboard of the drying room through numerous ventilation holes provided in the floorboard. The grain inside the drying chamber is suspended by a guide shaft installed in the upper part of the inner cavity so as to revolve around the approximate center of the drying chamber, and the vertical auger moves back and forth in the axial direction of the guide shaft. This is done by raising the grains one by one while changing the location, and when the grains are discharged from the drying chamber, the grains remaining on the floorboard are discharged using the axis of the floorboard as the center of revolution. A cylindrical drying chamber type in which a discharge auger mounted on the top of the floorboard rotates around the earth and rotates to sweep the grains out of the outlet provided at the shaft center of the floorboard. This invention relates to improvements to grain drying equipment.

An object of the present invention is to provide the above-mentioned grain drying apparatus with the aim of avoiding interference between the lower end of the vertical auger and the discharge auger disposed on the upper surface of the floorboard. Since it is configured to be spaced upwardly by a height corresponding to the diameter of the discharge auger, a considerable amount of stationary material is deposited on the upper surface of the floorboard to a thickness corresponding to the diameter of the discharge auger. The purpose is to produce grains, thereby solving the problem of a large number of degenerated grains due to excessive exposure to drying air (hot air).

Next, in FIG. 1, a grain drying apparatus according to the present invention for achieving this purpose is explained in detail with reference to an embodiment with reference to the drawings, A is a drying chamber a (or The drying chamber a (grain tank) is constructed by installing a tank 1 formed in a cylindrical shape on a base 2; By installing a breathable floor plate 3 such as a net or a perforated plate at a position slightly elevated from the top surface of the base 2 at the bottom of the inner cavity of the tank 1, the tank 1 above the floor plate 3 is installed.
It is constructed with a lumen.

Reference numeral 4 denotes a grain lifting machine (bucket elevator) installed outside the tank 1 to load grain into the drying chamber a, and 5 denotes a discharge port (not shown) installed at the upper end of the grain lifting machine 4. The grains discharged from the drying room a
A grain feeder (in this example, a belt conveyor) transports the grains to the upper part of the inner cavity of the grain feeder 5, and 6 equalizes the grains discharged from the discharge port 7 of the grain feeder 5 and releases them into the drying room a. Reference numeral 8 denotes a blower having an air outlet communicating with an air guide chamber 9 formed with a space below the floor plate 3 so as to send drying air (hot air) to the grains stretched in the drying chamber a; is an outlet provided at the axial center of the floor plate 3 to discharge the dried grains from the drying chamber a;
Reference numeral 11 designates the air guide chamber 9 of the floor plate 3 so as to carry out the grains flowing out from the outlet 10 to the outside of the tank 1.
A grain feeder (belt conveyor in this example), 12, which is arranged and installed in the drying chamber a, is installed in the drying chamber a to circulate and flow the grains loaded in the drying chamber a during the drying process. The vertical auger 13 is a guide shaft 1 provided to suspend and support the vertical augers 12 and to rotate while revolving around the upper part of the inner cavity of the drying chamber a in order to sequentially displace the vertical augers 12.
Reference numeral 4 denotes a guide ring provided on the support frame 15 of the vertical auger 12 so that the vertical auger 12 is displaced in the axial direction of the guide shaft 13 by the rotation of the guide shaft 13; 16 is the support frame 15; A switch 17 is provided on the guide shaft 13 so as to change the direction of rotation of the motor M by colliding with an abutting portion provided at 15, thereby switching the direction of rotation of the guide shaft 13 between forward and reverse. A vertical auger 20 supported so as to operate in a fixed position at the end portion is used to carry out the dried grains from the drying room a through the discharge port 10 by the operation of the grain feeder 11 mentioned above.
This is a discharge auger installed on the upper surface of the floorboard 3 so as to sweep out the grains remaining on the upper surface toward the discharge port 10.

The discharge auger 20 is connected to the discharge port 10.
A gearbox 22 that rotates with a vertical support shaft 21 is supported on a support member 31 arranged inside and fixedly supported by a stay 30, and the base end of a horizontally long auger shaft 23 is pivotally supported on the gearbox 22. At the same time, a wheel 24 that rotates together with the shaft 23 is provided at the tip of the auger shaft 23, and an inner end of the auger shaft 23 is provided in the inner cavity of the vertical support shaft 21 in the gear box 22. The auger shaft 23 is operated to rotate on its own axis by transmitting power to the transmission shaft and driving the transmission shaft to the prime mover shaft through an appropriate transmission mechanism.
The wheel 24 provided at the outer end rotates due to the rotation of the wheel 3, and the wheel 24 is driven to rotate around the revolution. As shown, the gearbox 22 is raised and lowered by rotating a lever lever 40 connected to a vertical support shaft 21 that pivotally supports the gearbox 22 using an electric cylinder 41.

50, the auger 20 for discharge is fitted into a part of the floor plate 3, and the auger 20
The groove is formed so that the auger 20 sinks downward from the floor surface 3a of the floor plate 3, and is formed into a U-shaped cross section with a depth that allows the auger 20 to fit into it. It is formed along the radial direction from the outlet 10. The portion on the outer end side of the bottom surface which is pressed by the wheel 24 at the outer end of the auger shaft 20 is formed on an elevating plate 51 that is raised and lowered by a lever rod 43 that is rotated by the operation of an electric cylinder 42.

Note that the trough 50 may be provided at a desired location on the floorboard 3, but it is preferable to position it so as to wrap it around the top surface of the grain feeder 11 for grain discharging, since grains will not accumulate in the trough 50. The grains are transferred to the grain feeder 1 by an opening/closing shutter appropriately provided on the bottom of the trough 50.
This is effective because it allows the liquid to be discharged onto the conveyance surface of No. 1.

Furthermore, in the means of the present invention, the auger 20 for carrying out may be moved up and down as long as it fits into the trough 50 from above the floorboard 3, and may be configured as appropriate. In conjunction with the operation, the transmission of power to the auger 20 may be controlled so that it is disconnected by the downward movement and connected by the upward movement.

Next, to explain the effects, in the apparatus of the present invention configured as described above, the grains are dried in the drying room a.
Since the auger 20 can be dropped into the valley 50 when drying the vertical auger 1
Even if the lower end of the auger 2 approaches the upper surface of the floorboard 3, it does not interfere with the discharge auger 20, so that deterioration of the grain due to overdrying and overheating can be prevented. When the discharge auger 20 is pulled out from the trough 50 to scrape out the remaining grains, it is when drying is completed and the operation of the vertical auger 12 is stopped. Stopped vertical auger 1
2... can be rotated through one revolution on the upper surface of the floor plate 3 from the position in front of it to the back side thereof without any hindrance.
