Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a grain feeding device for a dryer, and can be used in a circulation type grain dryer.

[Prior Art] A conventional circulating grain dryer configured by stacking a storage tank, a drying room, and a grain harvesting room has a structure in which the upper end of the storage tank is The upper part of the bucket-type elevator is configured to protrude upward.

With this conventional device, compared to an elevator,
Since the storage tank is configured to be low, the amount of grain that can be loaded is correspondingly small, and there is a drawback that it is not possible to increase the amount of grain that can be loaded.

In addition, Japanese Utility Model Application Publication No. 12992/1987, which is a conventional technology for livestock feed stacking towers such as grass and straw, discloses that the upper center of the livestock feed stacking tower is raised to accommodate a large amount of feed, and the supply pipes are Some supply pipes are slanted so that the terminal end is located upwards, but since this supply pipe blows up grass and straw, it cannot be used for grains with a heavy specific gravity, and it is also difficult to use the supply pipe in the upper center of the livestock feed accumulation tower. Since a hopper is provided in the part, there is a drawback that livestock feed cannot be effectively pushed up to the top of the livestock feed accumulation tower.

[Problems to be Solved by the Invention] Therefore, the present invention aims to reduce the wasted space of the dryer by making the height of the storage tank and the bucket-type elevator approximately the same, and to reduce the amount of wasted space in the dryer. The aim is to provide a storage tank for aircraft.

[Means for Solving the Problem] The technical means for solving this technical problem is to sequentially arrange the storage tank 2, drying room 3, and grain harvesting room 4 from the top to the bottom, and to Grain harvesting room 4
The dryer is a circulation type dryer in which the grains that have flowed down are circulated to the upper storage tank 2 by a bucket-type elevator 7, and the storage tank 2 is configured at approximately the same height as the bucket-type elevator 7. A diffusion blade 20 is provided in the upper center, and between the grain discharge port 9 of the bucket-type elevator 7 and the diffusion blade 20, there is a push-up transfer helix 14 that is inclined so that the diffusion blade 20 side is located upward. A grain feeding device in a dryer is provided with a grain transfer device 15 having a grain transfer device 15.

[Operations and Effects of the Invention] Since the height of the storage tank 2 is configured to be approximately the same height as the height of the bucket type elevator 7, the storage tank is 2 can be increased, and the diffusion blade 20 can be connected between the grain discharge port 9 of the bucket-type elevator 7 and the diffusion blade 20.
Since it is connected by a grain transfer device 15 with a push-up transfer helix 14 that is inclined so that the side is located upward, the grains are reliably conveyed to the upper diffusion vane 20 and transferred to the storage tank by the diffusion vane 20. The grains can be fully loaded to the top of the storage tank 2, and the top of the storage tank 2, which is at approximately the same height as the bucket elevator 7, can be effectively utilized. Since the bucket-type elevator does not protrude from the dryer, it can be accommodated in relatively low barns even though it is a dryer with a large capacity.

[Example] Hereinafter, an example of the present invention shown in the drawings will be described.

First, the configuration will be explained. The dryer 1 has a storage tank 2 in the upper part, a drying chamber 3 in the middle, and a grain harvesting chamber 4 in the lower part, which are connected in series.
The heat generated from the combustion device 5 placed on the front side of the
A suction exhaust device 6 provided on the opposite side of the drying chamber 3 is configured to circulate the drying chamber 3 as suction hot air, and the grains drawn out from the drying chamber 3 are placed in the center of the grain harvesting chamber 4. A harvesting helix 8 is installed to transfer grain to the lower side of a bucket-type elevator 7 installed on the side of the suction/exhaust device 6. A horizontal receiving gutter 10 provided at the discharge port 9 at the top of the bucket-type elevator 7 has a transfer gutter 11 so that the tip side located at the center of the upper part of the storage tank 2 is located higher than the elevator 7 side.
The horizontal receiving gutter 10 is equipped with a horizontal transfer helix 12, and the transfer gutter 11 is equipped with a push-up transfer helix 14.
2 and the push-up transfer helix 14 are connected via a joint 13 to constitute a grain transfer device 15.
Further, a gear box 16 is provided at the tip of the transfer gutter 11, one bevel gear 17 of this gear box 16 is interlocked and connected to the push-up transfer helix 14, a vertical shaft 19 protrudes from the other bevel gear 18, and a diffusion vane 20 is provided at the lower end. is fixed, and the grains discharged from the distal end outlet 21 of the transfer gutter 11 are uniformly spread into the storage tank 2 by the diffusion blades 20. In addition, 22 is a bucket conveyor of the elevator, 23 is a drive pulley that drives the elevator 7 and the grain harvesting helix 8, 24 is a driven pulley of the elevator 7, 25 is a drive pulley that drives the grain transfer device 15 and the spreading vane 20, 26 is a drive belt, and 27 is a grain receiving hopper.

On the other hand, in the conventional one, as shown in FIG. It is configured to extend to the center of the storage tank 2.

Next, we will discuss the effects. When the bucket type elevator 7 and the grain transfer device 15 are driven to put grains into the grain receiving hopper 27, the grains are lifted to the upper part by the bucket conveyor 22 of the elevator 7 and sent from the discharge port 9 to the horizontal receiving hopper. It is discharged into the gutter 10 and transferred by the horizontal transfer helix 12 therein, and then transferred by the cooperative action of the transfer gutter 11 and the push-up transfer helix 14, and is discharged onto the diffusion vane 20. Storage tank 2 under the action of
Evenly dispersed within. Then, the combustion device 5 and the suction/exhaust device 6 are driven, and the storage tank 2
The grains are passed from the drying chamber 3 into the drying chamber 3, hot air is passed between the grains, the grains are continuously dropped into the grain harvesting chamber 4, and the grains are transferred to the elevator 7 by the grain harvesting helix 8.
Here, if the moisture content of the grains is at the set dryness, the grains are taken out of the machine, and if the dryness is insufficient, the grains are passed through the drying chamber 4 again through the same route as last time.
