この発明は、循環型穀物乾燥機の制御装置に係

物乾燥機の分散制御装置に関する。[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a control device for a circulating grain dryer, and particularly to a control device for controlling a first shutter at an upper opening of a grain lifting machine depending on the amount of grain loaded. This invention relates to a distributed control device for a circulating grain dryer that controls the opening/closing angle.

The circulating grain dryer is equipped with a grain lifting machine, and a grain loading hopper is provided at the loading opening of the grain lifting machine. Then, the grain to be dried, which is put into the hopper, is lifted up, thrown into the storage section from the throwing outlet of the grain lifting machine, guided to the grain collecting section via the drying section, and then moved to the dryer by the lower conveyance mechanism. The grain is transferred to a grain lifting machine installed on one of the front and back sides, and then lifted up again by the grain lifting machine, and this cycle is repeated, during which time the grain is dried.

高が高くなる程顕著に表れる。 Conventionally, in a circulating grain dryer having a throwing type elevator, it is very difficult to uniformly disperse the grain thrown into the dryer according to the amount of loading. In other words, if the setting is made so that it can be evenly distributed when the amount of wadding is large, when the amount of wadding is small, the supply to the elevator mounting wall will decrease, exposing the drying air path and hindering the drying work. Come. In addition, if the setting is made so that the amount of filling can be uniformly distributed when the amount of filling is small, when the amount of filling is large, too much will be supplied near the elevator opening, leaving room on the wall side facing the opening. Despite this, I found myself unable to push myself any further. These phenomena become more pronounced as the total height of the dryer increases.

すべての乾燥穀物は排出口３４から機外へ排出さ
れる。 Next, when all of the dried grains are discharged outside the dryer, the first shutter 36 is at the first position a, and the second shutter 40, which is driven in conjunction with the first shutter 36, is at the upright position x. in position. In this state, the first shutter 36 and the second shutter 40 cooperate to block and close the input opening 32, and the discharge port 34 is fully opened.
All dried grains are discharged out of the machine through the outlet 34.
また、穀物に対し所定の乾燥が終了するまで

転させられる。 Further, until a predetermined level of drying of the grain is completed, the second shutter 40 is at the y position, which is a laid-down position rotated counterclockwise by an angle β1 from the x position. At this time, the first shutter 36 is rotated counterclockwise from the first position a, depending on the amount of grain loaded.
つまり、第４図に示す如く、穀物の張込量が少

に均一に分散されるものである。 That is, as shown in FIG. 4, when the amount of grain loaded is small, the first shutter 36 is moved at an angle α from the position a by the detection signal from the loaded amount sensor 44.
1 in the counterclockwise direction and is at the second position b. In this state, most of the grain is concentrated diagonally downward from the lower part of the input opening 32, so that the grain is uniformly distributed at the bottom of the storage section 6.
また、第５図に示す如く、穀物の張込量が中量

分散されるものである。 Further, as shown in FIG. 5, when the amount of grain put in is medium, the first shutter 36 is at the third position c, which is rotated counterclockwise by an angle α2 from the b position. In this state, grains are thrown diagonally downward from the lower half of the input opening 32, and are uniformly distributed in the middle of the storage section 6.
そしてまた、第６図に示す如く、穀物の張込量
が多量である場合には、第１シヤツタ３６はｃ位

穀機１４取付壁側と反対側に集中させるので、揚
穀機１４取付壁側に穀物が堆積して投入開口部３
２を閉塞することなく、均一に分散されるもので
ある。 As shown in FIG. 6, when a large amount of grain is loaded, the first shutter 36 is at the fourth position d, which is rotated counterclockwise by an angle α3 from the c position. In this state, the first
The shutter 36 is fully opened, and the grain to be thrown is mainly directed horizontally from the top of the input opening 32, thereby concentrating the grain on the opposite side of the wall to which the grain lifting machine 14 is attached in the storage section 6. As a result, grain accumulates on the wall where the grain lifting machine 14 is attached, and
2, and can be uniformly dispersed without clogging the cells.
これにより、穀物の張込量に応じて、例えば３
態様に第１シヤツタの開閉角度を変化させること

し得て、穀物乾燥作業の作業効率の向上に寄与す
る。 As a result, depending on the amount of grain loaded, for example, 3
Accordingly, the opening/closing angle of the first shutter can be changed, and the state of grain distribution within the storage section can be made substantially uniform, contributing to improvement in the work efficiency of grain drying work.
また、穀物排出の際には第１、第２シヤツタに

出用機構が不要であるとともに、効率良く穀物を
排出することができ、実用上有利である。 Furthermore, when discharging grains, by blocking the input opening with the first and second shutters, there is no need for any other discharging mechanism, and the grains can be discharged efficiently. It's advantageous.
更に、前記第１、第２シヤツタを制御部によつ
