Description

[Detailed Description of the Invention] "Industrial application field" The present invention is an adjustment processing machine in which dried grain is discharged to a wide range of places with respect to the dryer main body by a screw shaft driven only by the rotary power of the elevator. It facilitates the selection of the installation location, etc., and at the same time saves power consumption and simplifies the equipment, and automatically slows down the rotation of the screw shaft when more dry grain than necessary accumulates in the discharge gutter. The present invention relates to a discharging device in a grain dryer capable of preventing damage to the screw shaft.

“Conventional technology” Conventionally, the dried grain is dried while circulating and flowing by the dryer main body and the elevator, and the obtained dried grain is discharged through the drain trough and discharged to an appropriate place by the thrower device. A dryer is known and described in, for example, Japanese Utility Model Publication No. 50-13813 prior to the present application, and its contents will be described with reference to FIG. That is, the elevator 2 is provided on one side of the dryer main body 1.
Is attached to the lower part of the supply gutter 3 provided on the upper side of the elevator 2, and a grain distribution gutter 5 with a switching valve 4 slidably pivoted as a boundary is provided.
The discharge gutter 6 and the discharge gutter 6 are connected together, and the lower end of the discharge gutter 6 is connected to the hopper 9 of the thrower device 7 provided with the lifting cylinder 8 to discharge the grains dried in the dryer main body 1 to the discharge gutter 6, It is discharged to a desired position through the thrower device 7 and the fried food barrel 8.

"Problems to be solved by the device" By the way, in the conventional discharging device of this type of grain dryer, the thrower device for discharging the dried grain was installed at a predetermined position of the dryer body so that it could not be moved. If the height of the fried grain cylinder is not made considerably high, it is not possible to accurately achieve the discharging work to a wide range of places for the dryer body, and as a result, dry grains are supplied to the adjustment processing machine etc. in the next process. If you do, it may be difficult to install it, but when trying to feed it to a distant adjustment machine etc., the fried cylinder will inevitably become higher and protrude from the roof of the work place, so the discharge range is inevitable. It is regulated by the roof height of the work place, and when the amount of discharged dry grain is larger than the amount processed by the adjustment processing machine, etc., it cannot be pumped not only in the fried cylinder but also in the thrower device. There was a problem that the grain was full and the thrower device was damaged.

The present invention has been made in view of the above problems of the conventional technology, and an object of the present invention is to dry a dried grain with a low power consumption even if the roof of the drying workshop is low. Not only can the equipment be installed in a wide range of locations to facilitate the selection of installation locations for adjustment processing machines and the simplification of the equipment, but also due to the difference between the supply amount and the treatment amount In order to provide a discharging device in a grain dryer that prevents the screw shaft from being damaged by automatically slowing the rotation of the screw shaft when it stays in the grain, and can always convey an appropriate amount of dried grain. Is.

[Means for Solving the Problems] In order to achieve the above object, the discharging device in the grain dryer of the present invention has an elevator attached to one side of the dryer main body, and the dryer main body and the elevator are connected at the bottom. In the case where they are connected to each other through an upper connection gutter provided with a gutter and a discharge gutter, the lower end of the discharge gutter is connected to a supply side of a carry-out gutter which is horizontal so as to extend from the elevator toward one side, An upper pulley shaft mounted on the upper part of the elevator and a screw shaft rotatably laterally mounted in the carry-out gutter are transmission-coupled by a flexible shaft via a torque limiter.

Then, the left and right ends of the upper pulley shaft horizontally penetrating the upper part of the elevator are connected to the screw shaft through a torque limiter by a flexible shaft so that they can be exchangeably connected to each other in a wide range of places with respect to the dryer main body. It can be transported.

"Operation" When you want to carry out and supply the dried grain to the right side of the dryer body when viewed from the front, such as a hopper for adjustment processing machines, the base end side of a substantially horizontal carry-out gutter was provided in the upper connection gutter. Connect to the drain gutter and extend the carry-out gutter to the right side of the dryer body.
Therefore, a predetermined amount of the grain to be dried is put into the dryer main body through the elevator and the upper connection gutter, and this finishes drying while circulating and flowing the grain to be dried. When the grains to be dried are dried, the dried grains are supplied from the discharge gutter into the carry-out gutter. By the way, since the upper pulley shaft and the screw shaft are transmission-coupled via a flexible shaft, the screw shaft rotates lightly with the drive of the elevator, conveys the dry grain along the carry-out gutter, and is installed in advance on the right side. It is successively supplied to the hoppers of the adjustment processing machine etc. for adjustment processing.

During the unloading operation as described above, the supply amount from the unloading gutter is larger than the processing amount of the adjustment processing machine etc., so if the load exceeds the predetermined value on the screw shaft, the torque limiter is activated to operate the screw shaft. The number of rotations is reduced and the amount of dry grain transported is automatically adjusted, so that the proper amount of dry grain is constantly supplied from the discharge gutter.

Also, depending on the working conditions, if you want to supply an appropriate amount of dry grain to the hopper of the adjustment processing machine etc. installed on the left side of the dryer main body as shown in Fig. 5, remove the carry-out gutter and move it to the left side of the elevator. Connect the discharge gutter to the lower end of the discharge gutter so that it extends to the bottom, and remove the torque limiter and the flexible shaft shown in FIG. 2 from the upper pulley shaft. This is the upper pulley shaft on the opposite side of the torque limiter and the flexible shaft. If the same operation as described above is carried out after the dried grain is mounted on, the proper amount of dry grain is supplied to the hopper on the left side position.

[Example] An example will be described with reference to the drawings.

In the drawing, 101 is a dryer main body capable of being dried by hot dry air being blown to the dried grains that are filled and intermittently flowed down sequentially. Elevator 102 for circulating and flowing some dried grain in the machine body 101 to the upper part of the dryer body 101.
Is attached. The dryer main body 101 and the elevator 102 are connected to each other through a lower connection gutter 103 and an upper connection gutter 104 so as to communicate with each other, and a dry grain discharge gutter 105 is attached to a lower part of the upper connection gutter 104. The discharge gutter 105 can be connected to the upper connection gutter 104 or not connected to the upper connection gutter 104 by a switching operation of the switching valve 106.

107 is a dryer main body for the dry grain discharged from the discharge gutter 105.
Comparing with 101, it is a substantially horizontal carry-out gutter that can be discharged to either the left or right side.
At the base end side of 7, there is a mounting flange 10 connected to the drain gutter 105.
8 is provided and a screw shaft 109 for rotatably accommodating a screw shaft 109 for transporting dried grains to the unloading side. A discharge tube 110 is open-connected to the lower end of the carry-out gutter 107 on the terminal side. An upper pulley shaft 111 is horizontally installed at an upper position in the elevator 102 so that both ends of the upper pulley shaft 111 project from the elevator 102.
A torque limiter 112 is attached to either one of the left and right ends of 1, and the upper pulley shaft 111 on the side where the torque limiter 112 is attached and the screw shaft 109 extending from the carry-out gutter 107.
And are connected by a flexible shaft 113 for power transmission.

Therefore, either the left or right side of the upper pulley shaft 111 is connected to the screw shaft 109 via the torque limiter 112 and the flexible shaft 113.
If it is exchanged and connected via, the carry-out gutter 107 can be extended toward the right side or the left side with respect to the dryer main body 101, and the carry-out work over a wide range can be easily achieved. Reference numeral 114 is a hopper such as an adjustment processing machine.

"Effects of the Invention" Since the present invention is configured as described above, it has the following effects.

In the discharging device of the grain dryer according to claim 1, since the installation height of the carry-out gutter can be made as low as possible, even if the roof of the drying workshop is low, the dried grain can be accurately conveyed to a distant place,
Perhaps it is possible to adjust and process this, the screw shaft is driven by the power from the upper pulley shaft through the flexible shaft, so it is possible to eliminate the electric motor dedicated to the screw shaft and rotate it effectively with less power consumption. Therefore, the device can be simplified.

In addition, due to the difference between the supply amount and the processing amount, when more than necessary dry grain stays in the discharge gutter, the rotation of the screw shaft is automatically slowed by the operation of the torque limiter. It is possible to prevent the dry grain from staying inside, prevent damage to the screw shaft, and always carry out an appropriate amount of dry grain.

In the carry-out device of the grain dryer according to claim 2, the left and right ends of the upper pulley shaft, which is laid across the upper part of the elevator in a penetrating manner, and the screw shaft can be exchangeably power-coupled by a flexible shaft via a torque limiter. Therefore, the carry-out gutter can be installed in the left or right direction with respect to the elevator to efficiently convey the dry grain over a wide range.
