It has become. The power supply cord 33 is connected to, for example, a power supply device in the operation panel 114.

The transparent partition plate 4 is a transparent plate-shaped partition member provided so as to partition the inside of the box body 2 at a position below the light emitting device 3 and above the ceiling portion 100a of the accommodation chamber 101. Is.

The transparent partition plate 4 has a planar shape corresponding to an internal planar shape (rectangle) formed by being surrounded by four side plates 21, 22, 23, 24, and uses a transparent plate having a required thickness. It is configured. As the transparent partition plate 4, for example, a colorless and transparent acrylic plate or a polyvinyl chloride plate is applied. Further, the transparent partition plate 4 may be any one having transparency capable of transmitting light emitted from the light emitting device 3, and for example, a lightly colored transparent partition plate 4 can be applied.

Further, as shown in FIGS. 6 and 7, the transparent partition plate 4 is provided at a position above the ceiling portion 100a of the accommodation chamber 101 in the inside of the box body 2.

At this time, the transparent partition plate 4 may be arranged at a position where the distance D from the inner wall surface (ceiling surface) 101c of the ceiling portion 100a of the lower surface 4a is, for example, 3 mm or more and 40 mm or less. When this distance D is smaller than the above lower limit value, the transparent partition plate 4 moves because the rubbing residue generated when the transparent partition plate 4 described later moves is accumulated between the ceiling portion 100a and the transparent partition plate 4. There are problems such as difficulty in doing so. On the contrary, when the distance D exceeds the above upper limit value, there is a problem that a large amount of rubbing residue is accumulated between the transparent partition plate 4 and the ceiling portion 100a.

Further, as shown in FIGS. 6 to 8, the transparent partition plate 4 is provided so as to be movable so as to pull out the portion 41 existing inside the box body 2 to the outside of the box body 2.

It is fixed and attached to the upper surface by a fixing means such as a screw.

Further, the handle 46 is attached to the back plate 22 of the box body 2 when the second bent portion 46b whose end near the box body 2 is bent is moved in the direction E2 for pushing the transparent partition plate 4. It comes into contact with the bracket 48a and stops. Further, the handle 46 is shown when it is not necessary to move the transparent partition plate 4 after fitting the through hole provided in the second bent portion 46b into the protruding pin 48b provided so as to protrude from the bracket 48a. It is also configured so that it can be temporarily fixed by a fixing means such as a screw.

Further, as shown in FIGS. 6 and 7, the transparent partition plate 4 is stopped at one end of the internal portion 41 at a desired position when the transparent partition plate 4 is moved to the outside in the direction E1. A stop member 47 is provided. The desired position is set, for example, at a position where the innermost end portion of the inner portion 41 of the transparent partition plate 4 is not pulled out from the passage port 27 to the outside of the box body 2.

The stop member 47 is configured by using a member having a shape that protrudes upward from the upper surface 4a at one end of the internal portion 41 of the transparent partition plate 4 and comes into contact with the upper side 27a of the passage port 27 to stop. The stop member 47 is attached to the upper surface 4a at one end of the internal portion 41 of the transparent partition plate 4 by, for example, a fixing means such as a screw or an adhesive.

Further, as shown in FIGS. 4 to 6 and 10 and the like, the box body 2 has a reflector plate that hangs down from the opening 122 for lighting installation into the accommodation chamber 101 on the open bottom surface portion 26. 28 is provided.

As shown in FIGS. 4 to 6 and 9 and the like, the reflector 28 has a flat plate-shaped first reflector 28a extending downward from the lower end of the back plate 22 of the box 2 and the left side of the box 2. It is configured as a member having a flat plate-shaped second reflector 28b extending downward from the lower end of the face plate 23 and a flat plate-shaped third reflector 28c extending downward from the lower end of the right side plate 24 of the box body 2. .. That is, the reflector 28 exists at each lower position of the back plate 22, the left side plate 23, and the right side plate 24 of the box body 2 and has a shape that surrounds the three surfaces, while the lower side of the front plate 21. The one surface existing at the side position and the surface directly below surrounded by the above three surfaces have an open shape.

In the first embodiment, as shown in FIG. 6, the opening 122 for installing the lighting has a relationship in which the dimension in the front-rear direction of the box 2 is shorter than the front-rear opening dimension of the bottom surface portion 26. Therefore, the widths of the second reflector 28b and the third reflector 28c are narrower than the widths of the left side plate 23 and the right side plate 24. Further, the reflector 28 is arranged and used so that the first reflector 28a faces the see-through window 117 on the side wall surface 101a of the accommodation chamber 101 (FIG. 9).

<Installation and use of lighting equipment>
As shown in FIGS. 4 and 9, the lighting device 1A is installed and used in the opening 122 for lighting installation in the ceiling portion 100a of the crop dryer 100.

First, the opening 122 for lighting installation in the first embodiment is, for example, as shown in FIG. 9B, at one corner of the four corners of the rectangular ceiling portion 100a, and is seen through the side wall surface 101a of the accommodation chamber 101. It is provided as a rectangular opening slightly tilted toward the window 117.

Therefore, as shown in FIGS. 4, 6, 10, 10 and the like, the lighting device 1A inserts the reflector 28 from the opening 122 for installing the lighting and allows the light device 1A to exist inside the storage chamber 101 and is present in the box. The bent portions 21a, 22a, 23a, 24a of the side plates 21, 22, 23, 24 of the body 2 are attached in a state of being installed around the opening 122 in the ceiling portion 100a. The box body 2 at this time is fixed to the ceiling portion 100a by a fixing means such as a screw. Further, the power supply cord 33 of the light emitting device 3 is connected to a power supply device or the like in the operation panel 114.

Further, the lighting device 1A is configured so that the light emitting device 3 can be turned on and off at an arbitrary time by operating, for example, an ON / OFF switch for lighting (not shown) provided on the operation panel 114. .. Further, the lighting device 1A turns on and off the light emitting device 3 in conjunction with the operation of a predetermined operation (tensioning operation, circulation operation, drying operation, discharging operation, etc.) selected and instructed by operating the operation panel 114. Is also configured to be done automatically.

Then, the lighting device 1A is used, for example, as follows during the tensioning operation.

First, when the light emitting device 3 is automatically turned on by the on operation of the on / off switch or in conjunction with the tensioning operation, the lighting device 1A starts from the light emitting device 3 as shown by the two-dot chain line arrow in FIG. After the light for lighting emitted passes through the transparent partition plate 4 from the inside of the box body 2, it passes through the bottom surface portion of the box body 2 and the opening 122 for lighting installation in the ceiling portion 100a, and is inside the accommodation chamber 101. Is irradiated to.

At this time, the light from the light emitting device 3 directly reaches the see-through window 117 on the side wall surface 101a of the storage room 101 from the light emitting device 3 when the crop is not housed in the storage room 101. , There is one that reaches the perspective window 117 after being reflected by the reflector 28. In addition, it goes without saying that some of the light from the light emitting device 3 reaches the perspective window 117 as a part of the light reflected on the inner wall surface of the accommodation chamber 101 when the inside of the accommodation chamber 101 is illuminated. stomach.

As a result, when the light reaches the see-through window 117, a part of the light K passes through the see-through window 117 and leaks to the outside of the accommodation chamber 101 as illustrated by the arrow of the alternate long and short dash line in FIG. ..

Subsequently, when the crop is squeezed into the containment chamber 101 by the staking operation and begins to be accommodated, the lower one of the plurality of perspective windows 117 is blocked by the crop from the inside of the containment chamber 101.

As a result, the light from the light emitting device 3 does not reach the perspective window 117 that is blocked from the inside by the crop, but reaches the perspective window 117 that is not blocked by the crop. It will be like.

Here, for example, it is assumed that the crop is contained up to the height of the sedimentary surface 200a shown by the two-dot chain line in FIG.

In this case, the light from the light emitting device 3 does not reach the perspective window 117b of the group existing below the height of the sedimentary surface 200a of the crop. Therefore, almost no light K leaks to the outside of the accommodation chamber 101 from the see-through window 117b of the group, and the see-through window 117b of the group is visually recognized as a dark see-through window 117b. On the other hand, the light from the light emitting device 3 reaches the see-through window 117a of the group existing above the height of the crop surface 200a. Therefore, the light K leaking to the outside of the accommodation chamber 101 exists from the see-through window 117a of the group, and the see-through window 117a of the group is visually recognized as a bright see-through window 117a.

Therefore, in the crop dryer 100 equipped with the lighting device 1A, the darkest transparent window 117b (or one below the bright transparent window 117a) which is visible as the dark transparent window 117b in the accommodation chamber 101 is dark. It can be seen that the crop is contained up to the height of the see-through window 117a).

<Effects of lighting equipment>
Then, in the crop dryer 100, regardless of the presence or absence of the lighting device 1A, dust is generated from the crops and the like stored in the storage chamber 101 when each operation such as the staking operation is performed, and the storage room 101 is vacant. It floats so as to diffuse the space. Further, a part of the dust may move so as to approach the lighting device 1A.

However, in this lighting device 1A, the approaching dust from entering the inside of the box body 2 is blocked by the transparent partition plate 4 and prevented.

Therefore, according to the lighting device 1A, it is possible to prevent the dust from adhering to the light emitting device 3 mounted inside the box body 2 and reducing the brightness of the lighting. As a result, it is less likely that it will be difficult to visually confirm the amount of crops stored in the storage chamber 101 of the crop dryer 100 through the fluoroscopic window 117 due to the adhesion of dust to the light emitting device 3.

Further, in the lighting device 1A, since the transparent partition plate 4 is arranged at a position above the ceiling portion 100a inside the box body 2, the transparent partition plate 4 is located at the same position (height) as the ceiling portion 100a. Compared to the case where the dust is arranged, even if the dust moves along the ceiling portion 100a and approaches, the dust does not reach the transparent partition plate 4 directly and is less likely to adhere to the transparent partition plate 4. .. Further, in this case, it becomes easy to prevent the crops housed in the storage chamber 101 from coming into contact with the transparent partition plate 4.

Moreover, since the lighting device 1A is provided with a reflector 28 hanging from the inside of the accommodation chamber 101 on the bottom surface of the box body 2, the lighting device 1A is compared with the case where the reflector 28 is not provided. The dust that approaches the surface is blocked by the reflector 28 or the course is changed, so that the dust does not reach the transparent partition plate 4 directly and is less likely to adhere to the transparent partition plate 4.

Therefore, in the lighting device 1A, the transmittance of the light from the light emitting device 3 is suppressed from being reduced by the transparent partition plate 4 to which dust is attached, and this also causes the brightness of the lighting to be reduced. It is prevented from being lowered.

Further, in the lighting device 1A, the portion 41 in which the transparent partition plate 4 exists inside the box body 2 can be moved to the outside of the box body 2, and when the transparent partition plate 4 is moved, the upper and lower surfaces 4a and 4b of the transparent partition plate 4 can be moved. A cleaning member 5 (51, 52) that comes into contact with the passage port 27 for cleaning is provided.

Therefore, for example, when the transparent partition plate 4 is contaminated by the adhesion of dust or the like, as shown in FIG. 8, at least the internal portion 41 of the transparent partition plate 4 is pulled out to the outside of the box body 2 and moved. If the upper and lower surfaces 4a and 4b are brought into contact with the cleaning member 5 (51, 52), the dust is removed and the cleaning is performed. As a result, the translucency of the transparent partition plate 4 is suppressed from being lowered by the adhesion of dust.

Therefore, in the lighting device 1A, it is possible to prevent the transmittance of the light from the light emitting device 3 in the transparent partition plate 4 from being reduced due to dust adhering to the transparent partition plate 4, which also causes the brightness of the illumination. It is prevented from decreasing.

However, in this lighting device 1A, when the transparent partition plate 4 is moved and the cleaning work is performed by the cleaning member 5, the worker uses the work ladder 119 to reach the ceiling portion 100a of the crop dryer 100. After climbing, the work of moving the transparent partition plate 4 by holding the handle 46 of the transparent partition plate 4 in the lighting device 1A will be performed.

At this time, the transparent partition plate 4 may only need to move in the pull-out direction E1 and reciprocate in the push-in direction E2 once, but for example, it is difficult to remove dirt due to adhesion of dust or the like on the transparent partition plate 4. Occasionally, the reciprocating movement is performed multiple times. In any case, according to the lighting device 1A, the cleaning work of moving and cleaning the transparent partition plate 4 can be easily performed outside the box body 2.

[Embodiment 2]
FIG. 11 shows a crop dryer 100 to which the lighting device 1B according to the second embodiment of the present invention is applied.

The lighting device 1B has the same configuration as the lighting device 1A according to the first embodiment, except that a configuration for automatically moving the transparent partition plate 4 in the lighting device 1B is added.

The lighting device 1B is a moving device 6 for moving the transparent partition plate 4 with respect to the box body 2 and a first operating means 69 for operating the moving device 6 with respect to the lighting device 1A according to the first embodiment. And are newly added and prepared.

The moving device 6 is a device including a drive unit 6a that drives the transparent partition plate 4 to move in the pull-out direction E1 and the push-in direction E2, and a transmission unit 6b that transmits the power of the drive unit 6a to the transparent partition plate 4. be. The drive unit 6a is configured by using, for example, a solenoid or the like.

Further, the moving device 6 is arranged on the ceiling portion 100a of the crop dryer 100 in a state of being connected to the box body 2 of the lighting device 1B separately. However, the moving device 6 may be provided so as to be integrated with the box body 2 of the lighting device 1B.

The first operating means 69 is provided as a part of the operating function on a part of the operation panel 114 provided in the lower part of the crop dryer 100. The first operating means 69 is composed of, for example, a moving switch for turning on / off the operation of the driving unit 6a in the moving device 6. In this case, the first operating means 69 may be divided into a switch for moving the transparent partition plate 4 in the pull-out direction E1 and a switch for moving the transparent partition plate 4 in the push-in direction E2. Further, the first operating means 69 is connected to the drive unit 6a in the mobile device 6 by a wiring 6c for supplying electric power and transmitting a control signal.

According to the lighting device 1B provided with the moving device 6 and the first operating means 69, when the transparent partition plate 4 is moved and cleaned by the cleaning member 5, the worker performs the cleaning work of the crop dryer 100. It is not necessary to rise to the ceiling portion 100a, and this can be easily performed by operating the first operating means 69 arranged at the lower part of the crop dryer 100.

As a result, the transparent partition plate 4 in the lighting device 1B is automatically moved to the pull-out direction E1 and the push-in direction E2 by transmitting the operation of the drive unit 6a of the moving device 6 by the transmission unit 6b. By this movement, the upper and lower surfaces 4a and 4b of the transparent partition plate 4 come into contact with the cleaning members 51 and 52 on the outside of the passage port 27 of the box body 2 and are cleaned.

The movement operation of the transparent partition plate 4 by the moving device 6 is automatically executed when the movement such as the tensioning operation is completed, instead of being performed when instructed by the operation of the first operating means 69. It may be configured as follows.

Further, as the mobile device 6 in the lighting device 1B, for example, the mobile devices 61 and 65 having the configurations exemplified in FIGS. 12 and 13 are applied.

The moving device 61 shown in FIG. 12 is formed by applying a lagging type link mechanism 62 to form a driving unit 6a and a transmitting unit 6b. Further, the first operating means 69 in the moving device 61 is composed of an operating lever 69a for inputting power to the link mechanism 62.

The link mechanism 62 in the moving device 61 has two links 62b and 62c attached to the portion corresponding to the handle 46 of the transparent partition plate 4 via the shaft 62a with respect to the horizontal guide groove 62d formed in the main body of the moving device 61. The two links 62f and 62g attached so as to intersect the moving moving shaft 62e are connected by a joint shaft, and the link 62f is configured as a driving link.

Further, in this link mechanism 62, the free end of the link 62f as the driving link is connected to one end of the swing bar 63b that swings with respect to the shaft 63a provided in the main body of the moving device 61 via a connecting means 63c such as a wire. Is connected.

The other end of the rocking bar 63b is connected to the operating lever 69a arranged at the bottom of the crop dryer 100 by a connecting means 63d such as a wire or a rod. The operating lever 69a is configured so that, for example, when lowered downward, a force for lowering the other end of the swing bar 63b can be transmitted via the connecting means 63d.

Further, the link mechanism 62 is provided with a pressing coil spring 64 between the main body of the moving device 61 and the lower protrusion 46a of the handle 46 of the transparent partition plate 4.

The pressing coil spring 64 is a spring that generates a force that pushes the transparent partition plate 4 into the inside of the box 2 in the direction E2, and is in a contracted state particularly when the transparent partition plate 4 is pulled out from the inside of the box 2. It is a spring that functions to increase the pushing force in the pushing direction E2 for pushing the transparent partition plate 4.

Further, in the link mechanism 62, in addition to the coil spring 64, the coil spring 62h is arranged between the free end of the link 62c and the ceiling portion 100a, and the free end of the link 62c is elastically pushed upward. It may be configured to keep it in a state.

In the lighting device 1B to which the moving device 61 is applied as the moving device 6, when the cleaning work by moving the transparent partition plate 4 is unnecessary, it is not necessary to operate the operation lever 69a as the first operating means 69.

At this time, as shown in FIG. 12A, since the transparent partition plate 4 in the lighting device 1B continues to be pushed in the pushing direction E2 by the pushing force of the pressing coil spring 64, the transparent partition plate 4 of the transparent partition plate 4 is continuously pushed. The internal portion 41 is kept in a state of being housed inside the box body 2. Further, at this time, the link mechanism 62 has a form in which the entire link mechanism 62 is extended corresponding to the position of the shaft 62a on the handle 46 of the transparent partition plate 4.

Further, in the lighting device 1B, when the cleaning work by moving the transparent partition plate 4 is required, the worker on the installation surface 9 of the crop dryer 100 operates the operation lever 69a as the first operation means 69.

That is, at this time, as shown in FIG. 12B, the operator operates the operation lever 69a so as to lower it in the downward direction indicated by the arrow J. As a result, the swing bar 63b in the moving device 61 swings so as to rotate to the right side in the drawing with the shaft 63a as a fulcrum, so that one end of the swing bar 63b is in the link mechanism 62 via the connecting means 63d. The end of the link 62f is lifted, and the entire link 62f is swung so as to rotate to the left with the moving shaft 62e as a fulcrum. Further, as a result, as shown in FIG. 12B, the link mechanism 62 is in a state of being entirely folded while moving toward the side where the swing bar 63b is located.

As a result, the transparent partition plate 4 in the lighting device 1B is moved in the direction E1 pulled out by the link mechanism 62 of the moving device 61. By this movement, the upper and lower surfaces 4a and 4b of the transparent partition plate 4 come into contact with the cleaning members 51 and 52 on the outside of the passage port 27 of the box body 2 and are cleaned.

In the moving device 61, the pressing coil spring 64 is in a contracted state as the transparent partition plate 4 moves in the drawing direction E1. Therefore, when the operating lever 69a in the lowered state is released, the pressing coil spring 64 is restored. Therefore, the restoring force causes the transparent partition plate 4 to be moved in the pushing direction E2, and the internal portion 41 thereof is moved. It will be returned to the inside of the box 2.

Therefore, in the moving device 61, when the transparent partition plate 4 is moved in the pushing direction E2, an operation such as lifting the operation lever 69a becomes unnecessary, and the labor in the cleaning work is reduced accordingly. Further, when the coil spring 62h is arranged, when the operating lever 69a is released from the lowered state, the coil spring 62h is restored from the contracted state (FIG. 12 (B)) (FIG. 12 (A)). Since the link 62g is returned to the original position, the transparent partition plate 4 is also moved in the pushing direction E2, and an operation such as lifting the operation lever 69a becomes unnecessary.

The moving device 65 shown in FIG. 13 comprises a driving unit 6a and a transmitting unit 6b by applying a wire driving mechanism 67 that moves the wire 66 attached to the transparent partition plate 4 so as to move it. Further, the first operating means 69 in the moving device 65 is composed of a switch or the like for turning on / off the operation of the wire driving mechanism 67.

The wire 66 in the moving device 65 has one end 66a fixed to the stop member 47 at the end of the internal portion 41 of the transparent partition plate 4 in the lighting device 1B, and the other end 66b is an exposed portion of the transparent partition plate 4. It is a wire fixed to the handle 46 in. One end portion 66a of the wire 66 can exist inside the box body 2 through a through hole (not shown) provided in the front plate 21 of the box body 2.

Further, the wire drive mechanism 67 in the moving device 65 winds and holds a substantially intermediate portion of the wire 66 around a rotating drum 67a, and electrically drives the rotating drum 67a in a required direction in accordance with the moving direction of the transparent partition plate 4. It is a mechanism that is rotated by a drive source such as a motor to move the wire 66 in a required direction. The wire drive mechanism 67 is connected to the first operating means 69 by a connection wiring 67b that supplies electric power and transmits a control signal.

Further, the first operating means 69 can select and instruct the rotation direction of the rotary drum 67a in the wire drive mechanism 67 according to the moving direction of the transparent partition plate 4.

In the lighting device 1B to which the moving device 65 is applied as the moving device 6, when the cleaning work by moving the transparent partition plate 4 is unnecessary, the operation of the first operating means 69 and the operation of the wire drive mechanism 67 are also unnecessary.

At this time, as shown in FIG. 13A, the internal portion 41 of the transparent partition plate 4 in the lighting device 1B is housed inside the box body 2 due to the initial setting movement position of the wire 66. It is kept. That is, in this moving device 65, the position of the wire 66 is fixed at the position when the rotating drum 67a of the wire driving mechanism 67 rotates and stops, and when the wire 66 does not move, the transparent partition plate 4 also stops. It is a mechanism that can be maintained.

Further, in the lighting device 1B, when the cleaning work by moving the transparent partition plate 4 is required, the worker on the installation surface 9 of the crop dryer 100 operates the first operating means 69.

That is, at this time, as shown in FIG. 13B, the worker operates the first operating means 69 to rotate the rotating drum 67a of the wire driving mechanism 67 clockwise as shown by the arrow. As a result, the wire 66 wound around the rotating drum 67a of the wire drive mechanism 67 is moved so that the other end 66b moves in the drawing direction E1 of the transparent partition plate 4. At this time, one end portion 66a of the wire 66 can also be moved so as to move by the same distance in the drawing direction E1 of the transparent partition plate 4.

As a result, the transparent partition plate 4 in the lighting device 1B is moved in the direction E1 drawn out in synchronization with the movement of the wire 66 moved by the wire drive mechanism 67 of the moving device 65.

By this movement, the upper and lower surfaces 4a and 4b of the transparent partition plate 4 come into contact with the cleaning members 51 and 52 on the outside of the passage port 27 of the box body 2 and are cleaned.

Further, as shown in FIG. 13A, the pulled out transparent partition plate 4 is operated by an operator to rotate the rotating drum 67a of the wire driving mechanism 67 counterclockwise in the first operating means 69 as shown by an arrow. By doing so, the transparent partition plate 4 is moved in the direction E2 in which the transparent partition plate 4 is pushed by the movement of the wire 66.

[Embodiment 4]
FIG. 17 shows a crop dryer 100 to which the lighting device 1D according to the fourth embodiment of the present invention is applied.

The illuminating device 1D is the same as the illuminating device 1B according to the second embodiment except that the illuminating device 1D is provided with a displacement means 8 for displacing the light emitting device 3 and a second operating means 89 for operating the illuminating means 8. It consists of a structure.

As shown in FIG. 17A, the displacement means 8 in the lighting device 1D swings the light emitting device 3 in the box body 2 in the substantially horizontal direction with the support shaft 81a as a fulcrum as indicated by the double-headed arrow P. At least one of the swinging portion 81 to be moved and the raising / lowering portion 82 to move the support shaft 81a supporting the light emitting device 3 back and forth so as to move up and down in the vertical direction as shown by the double-headed arrow Q, and the swinging portion 81 and the raising / lowering portion 82. It is provided with a drive unit 83 for driving the above.

Of these, the swing portion 81 is configured by, for example, a mechanism that rotates the support shaft 81a in the forward and reverse directions within a required angle range. Further, the elevating portion 82 is configured by, for example, a mechanism for moving the support member 82a supporting the support shaft 81a up and down along a guide groove 82b extending up and down. Further, the drive unit 83 is configured by using an electric motor, a gear mechanism, or the like that supplies power necessary for swinging at the swinging portion 81 and raising / lowering at the raising / lowering portion 82.

As a result, the light emitted from the box 2 into the storage chamber 101 of the crop dryer 100 is emitted so as to sway in the horizontal direction or the vertical direction.

Therefore, according to the lighting device 1D, since the light emitting device 3 is displaced in the horizontal direction or the vertical direction by the displacement means 8, the light leaking to the outside from the see-through window 117 in the accommodation chamber 101 is compared with the case where the light emitting device is not displaced. K (FIG. 10) is also emitted in a swaying manner and becomes conspicuous. Therefore, in this lighting device 1D, it becomes easy to visually confirm the amount of crops contained in the accommodation chamber 101 through the see-through window 117.

Further, according to the lighting device 1D, the work of displacing the light emitting device 3 by the displacement means 8 does not reach the ceiling portion 100a of the accommodation chamber 101, but operates the second operation means 89 at the lower part of the accommodation chamber 101. This can be done easily.

In this lighting device 1D, the displacement means 8 is not operated in response to the operation of the second operating means 89, but the displacement means 8 is automatically operated in conjunction with the operation such as the tensioning operation. It may be configured.

[Modification example]
The present invention is not limited to the contents exemplified in Embodiments 1-4, and various modifications can be made without changing the gist of each invention described in the claims, for example, the following. It also includes modifications such as those listed in.

In the first embodiment, the case where the transparent partition plate 4 is movably provided with respect to the box body 2 and the cleaning member 5 is provided in contact with the transparent partition plate 4 for cleaning is exemplified in the lighting device 1A. However, the lighting device 1A can be configured so that the transparent partition plate 4 is provided in a non-moving state and the cleaning member 5 is not provided.

In the lighting device 1A configured in this way, cleaning cannot be performed by moving the transparent partition plate 4 with respect to the box body 2 and bringing it into contact with the cleaning member 5, but dust generated in the storage chamber 101 is collected in the box. The transparent partition plate 4 can prevent the light emitting device 3 mounted inside the body 2 from adhering to the light emitting device 3.

In the first and second embodiments, as the cleaning member 5 in the lighting devices 1A and 1B, a pair of cleaning members 51 and 52 in contact with the upper surface 4a and the lower surface 4b of the transparent partition plate 4 is provided as an example. However, in the lighting devices 1A and 1B, only one cleaning member 51 that comes into contact with the lower surface 4b of the transparent partition plate 4 may be provided as the cleaning member 5.

In the lighting devices 1A and 1B configured in this way, when the transparent partition plate 4 is moved to the arrows E1 and E2, only the lower surface 4b is cleaned by the cleaning member 51 and the upper surface 4a is not cleaned, but it occurs in the accommodation chamber 101. Since the dust is likely to adhere to the lower surface 4b facing the inside of the storage chamber 101, it is sufficient to clean the lower surface 4b at least.

In the third embodiment, as the air injection member 7 in the lighting device 1C, a configuration in which air is blown to the lower surface 4b of the transparent partition plate 4 is exemplified. However, in the lighting device 1C, as the air injection member 7, an air injection member having a configuration in which air is blown onto both the upper surface 4a and the lower surface 4b of the transparent partition plate 4 may be applied.

In the lighting device 1C configured as described above, both the upper surface 4a and the lower surface 4b of the transparent partition plate 4 are cleaned by blowing air. When air is blown to the upper surface 4a of the transparent partition plate 4 by the air injection member 7, it is possible to prevent the blown air from staying inside the box 2 and adhering dust to the light emitting device 3. From the viewpoint of the above, for example, it is preferable to provide the box body 2 with an exhaust port, or to provide the box body 2 with an exhaust means for sucking and discharging the air inside the box body 2 above the transparent partition plate 4.

In the fourth embodiment, the case where the displacement means 8 and the second operating means 89 are applied to the lighting device 1B according to the second embodiment (actually, the lighting device 1D according to the fourth embodiment is included) has been described. The displacement means 8 and the second operating means 89 can be similarly applied to the lighting device 1A according to the first embodiment and the lighting device 1C according to the third embodiment.

Further, in the first and second embodiments, as a movable configuration of the transparent partition plate 4, a configuration example in which the transparent partition plate 4 is linearly reciprocated in the direction indicated by the arrows E1 and E2 with respect to the box body 2 is shown. rice field. However, the movable configuration of the transparent partition plate 4 is not limited to this, and other movable configurations may be adopted.

For example, as shown in FIG. 18, the transparent partition plate 4 is inside the box body 2 as shown by arrows R1 and R2 with the support shaft 49 provided at one corner of the rectangular parallelepiped box body 2 as a fulcrum. It is possible to adopt a mounting structure that rotates so as to move from the outside to the outside. R1 indicates a direction in which the transparent partition plate 4 is exposed, and R2 indicates a direction in which the transparent partition plate 4 is stored.

In this case, the passage ports 29a and 29b through which the transparent partition plate 4 is passed are provided on the two side surfaces of the box body 2, and the passage ports 29a and 29b protrude into the inside of the passage ports 29a and 29b at least downward of the passage ports 29a and 29b as the cleaning member 5. The bottom surface cleaning member 54 is provided in such a state. As for the cleaning member 5, it is preferable to provide a pair of upper and lower cleaning members arranged so as to be in contact with each other at an intermediate height between the passage ports 29a and 29b. Further, inside the box body 2, a support rail 43 substantially similar to the case of the support rail 43 in the lighting device 1A in which the internal portion 41 of the transparent partition plate 4 is supported is provided.

Then, in the transparent partition plate 4 having this configuration, when the cleaning work is required, the transparent partition plate 4 is rotated so as to reciprocate in both directions indicated by arrows R1 and R2 with the support shaft 49 as a fulcrum. At this time, the transparent partition plate 4 is cleaned by at least its lower surface 4b contacting and passing through the lower surface cleaning member 54.

The transparent partition plate 4 provided so as to be movable may be manually rotated, but a drive device for rotating the support shaft 49 in the forward and reverse directions is provided and automatically rotated. It is good to do it. Further, as the transparent partition plate 4 provided so as to be movable, a circular one may be adopted instead of a square one. In this case, it is preferable that the shape of the portion of the inside of the box 2 where the transparent partition plate 4 is arranged is also circular.

Further, in the first and fourth embodiments, a rectangular parallelepiped shape is exemplified as the box body 2, but if the bottom portion of the box body 2 is open and the light emitting device 3 can be attached and the light is emitted, another box body 2 is used. It is also possible to adopt a box body having a shape. Further, in some cases, the lighting device 1 may omit the provision of the reflector 28 on the box body 2.

Further, in the first embodiment, the case where the lighting device 1A-1D is attached to the crop dryer 100 to illuminate the inside of the storage chamber 101 is shown. However, the lighting device of the present invention represented by the lighting device 1A-1D can be applied to illuminate the storage room of another crop container that houses the crop, for example, the crop dryer 100. It can be applied to illuminate a storage room in a crop storage machine or the like equipped with a crop storage body that does not have a drying function and temporarily stores crops. In addition, the type of crop is not particularly limited.
