[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a shutter device in a grain dryer, which is provided between a grain dryer and a conveyor for loading grains into the grain dryer.

[0002]

[Prior art]

 Conventionally, grain drying facilities have been equipped with conveyors that carry grain into multiple grain dryers, and a shutter device that can be opened and closed is provided between the conveyor and each grain dryer. . In the conventional shutter device of this type, the opening or closing operation is opened and closed by alternately pulling the respective drawstrings.

[0003]

[Problems to be solved by the device]

 By the way, in this type of conventional shutter device, in order to open and close the sliding shutter plate with a drawstring, a pulley device that is slightly longer than the sliding distance of the shutter plate is attached to the shutter frame, and one end of the shutter plate is attached. Since the connected drawstring is hung down on the pulley device, the drawstring's hanging position is far from the shutter frame.

For this reason, the grip at the hanging end of the drawstring and the label plate are located away from the machine body, which not only hinders the work but also causes inconveniences such as hitting the head with the grip or the label plate. ing. Also, since the hanging end side of the drawstring is far away from the shutter frame, the stress when pulling the drawstring has a large effect on the shutter frame, so the opening and closing of the shutter is not smooth and the strength of the shutter frame is reduced accordingly. There was also a problem that the device had to be large-scale because it needed to be large.

The present invention has been devised in view of the above-mentioned conventional problems, in which the shutter can be opened and closed smoothly, and a drawstring for opening and closing the shutter plate is provided near the shutter frame. In a grain dryer that can be hung down so that it does not interfere with work, and the stress applied to the shutter frame via the pulley device when pulling the drawstring is reduced to simplify the installation. The purpose is to provide a shutter device.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, a shutter device in a grain dryer according to the present invention is a shutter device provided between a conveyor for loading grain into a grain dryer and a dryer, and a slide device for opening and closing an opening of a shutter frame. It is equipped with a movable shutter plate, and a shutter frame that opens and closes the shutter plate is attached to the shutter frame in a folded shape, and the shutter plate whose one end is connected to the shutter plate is opened and closed. The drawstring is folded over the pulley device and hung down on the shutter frame side.

[0007]

[Action]

 According to the shutter device in the grain dryer of the present invention, since the drawstring for opening and closing the shutter plate is hooked on the pulley device in a folded shape, the drawstring can be hung near the shutter frame. .

[0008]

【Example】

 FIG. 1 illustrates a grain drying facility. Reference numeral 13 denotes a grain dryer, and a plurality of the grain dryers 13 are provided, and the grain is carried into each of the dryers 13 by the conveyor 11. A shutter device 1 is provided between the conveyor 11 and each dryer 13.

As shown in FIGS. 2 to 5, the shutter device 1 is attached to a front plate 10 of a grain dryer 13 by a pedestal 12, and the shutter device 1 is attached to a shutter frame 2 and an opening portion thereof. The shutter frame 3 is provided with a slidable shutter plate 3 for opening and closing 14, and a pulley device 4 is attached to the shutter frame 2. The pulley device 4 has a structure in which a drawstring 6 for opening the shutter plate 3 or a drawstring 7 for closing the shutter plate 3 is hooked in a folded manner. It is hung on the pulley device 4 in a folded shape, and the other end is suspended from the opening 5 of the pulley device 4 in the vicinity of the shutter frame 2. A grip 8 and an open label plate are attached to the drawstring 6, and a grip 9 and a closed label plate are attached to the drawstring 7, respectively.

The shutter device 1 of each grain dryer 13 opens the shutter plate 3 by pulling the drawstring 6 and closes the shutter plate 3 by pulling the drawstring 7, but the drawstrings 6 and 7 are placed on the shutter frame 2 side. Since it is hanging, the grips 8 and 9 of the drawstrings 6 and 7 and the label plate do not interfere with the work. Moreover, the stress applied to the shutter frame 2 via the pulley device 4 when the pull cords 6 and 7 are pulled is small, and not only can the device be simplified, but the shutter can be opened and closed smoothly.

[0011]

[Effect of device]

 According to the shutter device in the grain dryer of the present invention, the shutter can be opened and closed smoothly, and the pulling string for opening and closing the shutter plate is not hung near the shutter frame so as not to disturb the work. In addition, the stress applied to the shutter frame via the pulley device when the pull cord is pulled can be reduced, and the device can be simplified.
