[Detailed Description of the Invention] Industrial Application Field of the invention is that the grain carried into the carry-in gutter is precisely moved to the position of the upper cover of the dryer body by the scraping action of the conveying screw blade and the throwing action of the throwing blade. The present invention relates to a grain distribution device in a grain dryer which can be efficiently packed by storing a large amount of grain even in a grain dryer having a short height.

2. Description of the Related Art Conventionally, a grain distribution device equipped with a carry-in gutter in which a rotatable screw conveyor is installed inside is installed horizontally in a substantially central position of an upper cover that covers the upper part of the dryer body. Prior to the filing of the present application, there is a grain dryer in which a predetermined amount of grain is loaded into the main body of the dryer by the rotation operation of, or the grain which has been loaded is circulated and flowed in the main body of the dryer to finish the drying. It is known and described in Japanese Utility Model Publication No. 52-163549, and its contents will be described with reference to FIG. That is, a carry-in gutter 2 having a wall plate 3 surrounding the periphery just below an upper cover 8 covering the top of the dryer main body 1 and having a rotatable screw conveyor 4 mounted therein is horizontally arranged.

The bottom wall 5 of the carry-in gutter 2 has three drop openings 6a,
6b and 6c are opened respectively, and the upper side of the elevator 7 attached to one side of the dryer main body 1 is connected to the supply side of the carry-in gutter 2, so that the grain sent by the elevator 7 is carried in the gutter 2
3 drop ports 6 while the grain is carried in and then the grain is successively conveyed to the conveying side by the screw conveyor 4.
a, 6b, 6c are dropped one after another, and the dryer main body 1
A certain amount of grain is filled inside.

Problems to be solved by the invention By the way, with regard to the carry-in gutter in this type of conventional grain distribution apparatus, generally, the surroundings are all surrounded by the surrounding wall except for the drop openings provided at the center of the bottom plate, the front side, and the transfer end side. Since it is completely enclosed, even if it is tried to squeeze the grain into the dryer main body at the time of staking the grain, if the drop port is blocked by the spilled grain, the grain will be further packed. It cannot be supplied, and an undeposited space is inevitably formed inside the upper cover, and it is impossible to put grains into the inside of the upper cover.Although the supply place is only the drop opening on the bottom plate, The stake-in work cannot be carried out evenly and efficiently, and of course the stake-in time takes a considerable amount of time, and the problem arises that the height of the dryer body and the elevator is unnecessarily high. .

Means for Solving Problems The present invention solves the above problems, and the contents thereof will be described below with reference to FIGS. 1 and 2 corresponding to the embodiment.

That is, the upper cover 1 that covers the upper part of the dryer main body 101
A horizontally long carry-in gutter 104 having an open top 105 and an opening 106 at the bottom end on the transport end side is horizontally arranged directly below the center of 02. And the upper cover 102 and the carry-in gutter 104
To form a grain arranging chamber 103 having open sides. A conveyor shaft 107 is rotatably accommodated in the carry-in gutter 104. A conveyor screw blade 108 is attached to the conveyor shaft 107 located on the bottomed side 104a of the carry-in gutter 104, and a plurality of sprinkling blades 109 are radially attached to the conveyor shaft 107 located on the bottomless side, that is, the opening 106. Then, carry-in gutter 104
The grains supplied into the dryer main body 101 are sequentially and evenly filled into the dryer main body 101 from both sides of the carry-in gutter 104 by the scraping and discharging action by the rotation of the conveyer screw blades 108 in the conveying process. When the opening 106 on the conveying end side is closed by the filled grains, the conveying screw blade 10 is also filled.
It is configured so that the grain can be accurately filled up to the position of the upper cover 102 of the dryer main body 101 by the scraping and discharging action of No. 8 and the throwing action of the allotment blade 109.

Action Now, if the conveyor shaft 107 is rotated by an appropriate power, the carry-in screw blade 108 and the throwing blade 109 are simultaneously rotated. Therefore, when the grain is supplied into the carry-in gutter 104, the grain is dropped and filled into the dryer main body 101 from the top opening 105 of the carry-in gutter 104 by the scraping and discharging action of the conveying screw blades 108 that rotate in the conveying process, and the grain is scratched. Grain that has not been taken out and has been transported to the transport end side is fed through the opening 106 provided on the transport end side to the dryer main body 101.
It is dropped and filled in. Therefore, if the above-described carry-in operation is continued, the grain is filled up to the bottom of the carry-in gutter 104, and the opening 106 on the transport end side is blocked by the filled grain.

Therefore, if grains are further supplied into the carry-in gutter 104, the grains are sequentially scraped into the grain distribution chamber 103 from the upper opening 105 of the carry-in gutter 104 by the scraping and discharging action of the conveying screw blades 108 as in the above-described operation. The grains that have been highly filled up to the position of the upper cover 102 and that have been conveyed to the end of the conveyance are distributed and ejected in the left-right direction to a substantially equal amount by the ejection action of a plurality of rotating ejection blades 109.

Therefore, the grain fed into the carry-in gutter 104 having an open upper part is covered by the rotating conveying screw blade 108 with the scraping and discharging action and the throwing blade 109 with the upper cover on the left and right sides of the carry-in gutter 104. Highly filled up to the 102nd position, it is possible to accurately fill and store a large amount of grain.

When a predetermined amount of grain is filled and stored in the dryer body 101 as described above, the grain supply to the carry-in gutter 104 is stopped to finish the carry-in work, and then the filled grain is dried in the dryer body 1
01 is circulated and fluidized, and at the same time, the grain being circulated and fluidized is exposed to dry hot air to be dried to a predetermined water content, and the dried grain may be appropriately carried out of the dryer main body 101.

Embodiment An embodiment of a grain distribution device in a grain dryer according to the present invention will be described with reference to the accompanying drawings.

In the drawing, reference numeral 101 denotes a dryer main body which is entirely formed in a horizontally long rectangular tube shape, and the top of the dryer main body 101 is covered with an upper cover 102. A grain distribution chamber 103 is provided at a position just below the center of the upper cover 102, the upper surface is opened 105, and the bottom portion on the conveyance end side is opened 106.
The horizontally long carry-in gutter 104 is horizontally arranged. A conveyor shaft 107 is rotatably accommodated in the carry-in gutter 104, and the conveyor shaft 107 located on the bottomed side 104a of the carry-in gutter 104 carries the grain in the process of being carried in 1
The transport screw blades 108 capable of scraping out and discharging the left and right substantially even amounts from the upper surface opening portion 105 of 04, and the conveyor shaft 107 located at the bottomless side, that is, the opening portion 106 have been transported to the transport end side. A plurality of arbor blades 109 for arranging the grains to be radiated to the surroundings and in a substantially uniform manner are mounted respectively. Reference numeral 110 denotes an elevator attached to one side of the dryer main body 101, and an upper portion of the elevator 110 is connected to a supply side of the carry-in gutter 104 to supply the grain pumped by the elevator 110 to the carry-in gutter 104. Excuse me.

Therefore, according to the device of the present invention, the conveying screw blade 1
Grain can be filled up to the position of the upper cover 102 by the scraping and discharging action by the rotation of 08 and the throwing action by the rotation of the throwing blade 109, and as a result, even if the dryer main body 101 having a low height is large in capacity. The grain can be packed and stored, and an efficient drying operation can be easily achieved.

In effect, since the present invention has the above-described concrete configuration, the grain carried into the carry-in gutter 104 is conveyed by the conveying screw attached to the conveyor shaft 107 located on the bottom side in the conveying process. By the scraping and discharging action of the blades 108, substantially equal amounts are discharged and filled from both sides of the upper opening portion 105 of the carry-in gutter 104, and at the same time, the grain conveyed to the end of the carry-in gutter 104 is dropped and filled from the opening 106 at the bottom. Perhaps as much as possible, after the opening 106 at the bottom is blocked by the filling grain by the above action, the scraping and discharging action of the conveying screw blade 108 and the plurality of sprinkling blades 109 are performed.
The grain carried into the carry-in gutter 104 can be filled up to a high position of the upper cover 102 through the grain distribution chamber 103 due to the action of being thrown into the surroundings by the dryer, and as a result, the dryer main body 101 having a short height can be filled. At the same time, it is possible to accommodate a large amount of grain and easily achieve efficient grain drying work, and at the same time, to lower the height of the elevator 110 by lowering the installation position of the carry-in gutter 104 as much as possible. Play.
