Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a discharge device for a continuous flow grain dryer.

Grain that is newly fed into the dryer generally has a high moisture content and has not been subjected to sufficient rough selection, so a large amount of foreign matter is generated when the pre-drying is completed, and this is left in the dryer as it is when the main drying begins. It is usually put into. Furthermore, as the drying progresses, more foreign matter is generated, and these foreign matter may clog the discharge port or adhere to the side walls of the drying chamber, resulting in uneven grain discharge and uneven drying. There was a lot to do. This invention was made for the purpose of solving the above-mentioned problems caused by contaminants, and will be explained below.

A plurality of discharge ports for distributing and discharging dried grains, a swinging hopper provided in an inclined manner and swinging to transfer the grains discharged from the discharge ports to a conveyor provided on one side; It is equipped with a perforated plate that is integrally provided and separates impurities in the grain.

Next, to explain the embodiment shown in the drawings, FIG. 1 is a schematic diagram showing an example of how the dryer is used. 7, Elevator 8,
They are connected by 9, 10, etc., and constitute one drying plant. The grains in the relay tank 2 are supplied to the dryer 1 by a conveyor 4 and an elevator 8. The grains 12 supplied into the tank 11 from the ceiling of the dryer 1 gradually flow down inside the tank 11, but on the way, they are exposed to hot air from a hot air supply device 13 installed in the middle of the tank. It gradually dries up. A discharge device 15 is disposed at the lower end of the tank 11, and the grains discharged from the discharge device 15 are conveyed to each chamber 3a of the storage tank 3 by a conveyor 5, an elevator 9, and a conveyor 6. It is distributed and supplied to 3d. The grains in the storage tank 3 are further circulated and supplied to the dryer 1 by the conveyor 7 and elevator 10 as needed.

At the lower end of the tank 11 of the dryer, a plurality of discharge ports 16, 16, . The discharge device 15 includes an inclined hopper 17 having an inclined bottom surface and a funnel-shaped perforated plate 18 held inside the hopper 17. Inside the hopper 17, the perforated plate 18 further holds grains falling from the discharge port 16. A guide plate 19 leading upward is fixed. Hotupa 17
A discharge tube 20 is provided in the center of the perforated plate 18.
As shown in Figures 3 and 4, in the center of the
A groove 21 is provided with a chevron-shaped cross section that is high at the center and low at the outside. The perforated plate 18 functions as a sorting net for separating impurities 22, and the pores 23 are sized so that impurities such as wood grains do not pass through, but grains pass through. A sieve mesh may be used as the perforated plate 18.

The four corners of the hopper 17 holding the perforated plate 18 and the guide plate 19 are suspended from the legs 26 of the dryer by means of hanging belts 25, 25, . . . . Further, a connecting piece 27 is fixedly provided on the lower surface of the hopper 17, and a connecting rod 29 of an eccentric device 28 provided on the leg portion 26 is pivotally attached to this. The eccentric device 28 is driven by a motor 30,
The hopper 17, together with the perforated plate 18 and guide plate 19, is swung left and right.

In the above configuration, the grains discharged from the discharge ports 16, 16, . That is, the grains 12 fall onto the bottom surface of the hopper 17 and exit the discharge pipe 20.
The foreign matter 22 is supplied to the conveyor 5 through the
moves on the perforated plate according to the inclination of the perforated plate 18, falls into the groove 21, and falls into the receiver 40 through the opening 21a provided at the end of the groove 21. In this case, since the entire hopper is oscillating, the flow of grains and impurities is extremely smooth. Instead of the vibration by the eccentric, a suitable vibration device may be used to give the hopper minute vibrations.

As explained above, the discharge device according to the present invention includes a plurality of discharge ports for distributing and discharging dry grains,
A swinging hopper provided in an inclined manner and swinging to transfer the grains discharged from the discharge port to a conveyor provided on one side; and a swinging hopper provided integrally with the swinging hopper to remove impurities in the grains. Since it is equipped with a separating perforated plate, it has become possible to effectively remove foreign substances from the grains, and it has become possible to effectively prevent accidents such as uneven drying and poor discharge. The hopper that guides the grains from multiple discharge ports to the conveyor is a tilting, swinging hopper, so the height of this part can be lowered without reducing the throughput, and the perforated plate for sorting can also be made like this. , so the height of the entire device does not need to be very high. When grains are repeatedly supplied to one dryer for drying, the amount of foreign matter generated in the dryer increases, so the use of the present discharge device becomes even more effective.
