The present invention relates to an overflow device for a grain dryer that can reliably prevent overflowing grain caused by an imbalance between the amount of supply and the amount of processing through the grain trough from overflowing into the elevator and clogging the elevator.

[Conventional technology]

Conventionally, the overflow device for grain dryers was
A device disclosed in Japanese Patent No. 57-180298 is known, and as shown in FIG. A grain threshing window 5 opened at the bottom of the grain threshing cabinet 3 is equipped with a grain threshing gutter 6, and the grain threshing window 5 and the throwing passage 4 are connected to each other by a grain threshing casing 3 formed in the grain casing 3. The grain drier is alternately opened and closed by a freely openable shutter 7, and an overflow tube 8 is installed on one upper side of the grain drain 6 to discharge overflowing grain into the dryer main body 1. When the dried grains that have been dried by drying are supplied to the adjustment processing machine etc. through the grain drain 6 and the adjustment processing work is performed, if overflowing grains occur due to an imbalance between the amount of supply and the amount of processing, the automatic The overflowing grain is then discharged into the dryer main body 1 through the overflow tube 8,
This prevents the water from overflowing to the elevator 2 side.

[The problem that the idea aims to solve]

By the way, in the case of the overflow device in the above-mentioned known grain dryer, when an overflow phenomenon occurs in the grain throwing gutter and the elevator is about to become clogged, the throwing passage and the grain throwing gutter are opened and closed by a shutter. The operator had to repeat the operation of temporarily closing the dryer to prevent the dry grain from being supplied to the gutter, and then draining the overflowing grain through the overflow pipe and into the main body of the dryer. Not only is it necessary to perform the troublesome operation of adjusting the rotation of the opening/closing shutter each time while inspecting the overflow condition, but a pile of overflow grains forms near the overflow tube, and this causes the overflow from the pile. If the cylinder is blocked and the overflowing grains overflow into the throwing elevator, clogging the throwing elevator, or if you try to feed dry grain to the hulling machine to perform hulling work, the hulling machine This has caused problems such as a change in the flow rate to the rice hull, resulting in a decrease in hulling performance.

The present invention was devised in view of the above-mentioned problems of the conventional technology, and its purpose is to process and process dried grains after they have been dried in a grain dryer using a grain sluice. Grain that can reliably prevent overflowing grain caused by an imbalance between the amount fed and the amount processed to overflow into the elevator from the grain disposal gutter and clog the elevator when the grain is fed to the elevator and processed for adjustment processing. It is intended to provide an overflow device in a dryer.

[Means to solve the problem]

In order to achieve the above object, the overflow device in the grain dryer according to the present invention has the upper side of the dryer main body 101 and the upper side of the throwing elevator 102 arranged in parallel formed into a throwing passage 104 inside. The opening on one side is connected in an upwardly inclined manner to a throwing window 105 opened at the upper part of the throwing elevator 102, and the opening on the other side is connected in a downwardly inclined manner to a loading window 106 opened at the upper part of the dryer main body 101. A grain threshing gutter 108 is attached to a grain threshing window 107 opened at the bottom of the grain shredding cabinet 103, and the grain threshing window 107 and the throwing passage 104 are connected to each other in the vicinity of the grain threshing window. In the dryer which is alternately opened and closed by an opening/closing shutter 109 mounted on an upper part of the dryer main body 101 so as to be rotatable from side to side, the grain removal gutter 108 is
Inside the dryer main body 101 on the side facing the dryer main body 101, an overflow shutter 112 is provided at the upper end opening 111 and is rotated downward about a pivot shaft under the weight load of overflowing grains, and the lower end is connected to the dryer main body. An overflow tank 110 opened in the interior 101 is installed vertically.

[Effect]

First, when grain is to be loaded into the dryer main body 101, the throwing elevator 102 is operated, and then the opening/closing shutter 109 is rotated to close the grain throwing window 107 and open the throwing passage 104. Then, the grains thrown from the throwing window 105 pass through the throwing passage 104, are thrown into the dryer main body 101 from the throwing window 106, and are rolled into the dryer main body 101. With the above operations, the dryer main unit 10
When a predetermined amount of grain has been loaded into the dryer body 101, the loading operation is stopped and the grain is circulated through the dryer main body 101 several times using a throwing elevator 102 to dry it. Next, when it is desired to process the dried grains using a conditioning machine or the like, connect the lower end of the grain drain 108 to the conditioning machine, etc., close the throwing passage 104 with the opening/closing shutter 109, and the thrown grains will collide with the opening/closing shutter 109. Then, the grain enters the grain threshing trough 108 through the grain threshing window 107 and is supplied to the adjustment processing machine and the like. By the way, when the amount supplied from the grain threshing gutter 108 is larger than the processing amount of the adjustment processing machine, etc., the overflowing grain gradually overflows into the dryer main body 101 facing the grain threshing gutter 108 side from the grain threshing window 107, Overflow shutter 11
2. Therefore, when the amount of overflow grains generated gradually increases, the overflow shutter 112 is rotated downward about the pivot shaft 113 due to the weight load of the overflow grains, and the upper end opening 111 is opened to release the overflow grains. The grains are dropped into the flow tank 110 and further discharged from the lower end opening 114 into the dryer main body 101 to be mixed with the grains being circulated and flowed.

Therefore, during dry grain rationing,
Even if an overflow phenomenon occurs, the overflow grains can be returned to the dryer main body 101 for treatment without having to adjust the rotation of the opening/closing shutter 109 each time, and the overflow grains can be overflowed to the throwing elevator 102. In addition to reliably preventing the clogging phenomenon from occurring, it is possible to supply a fixed amount of dry grain to a conditioning processing machine or the like.
