It is configured. As the transparent partition plate 4, for example, a colorless and transparent acrylic plate or polyvinyl chloride plate is applied. Moreover, the transparent partition plate 4 may be any one having transparency that allows the light emitted from the light emitting device 3 to pass therethrough, and for example, a thinly colored transparent plate is also applicable.

6 and 7, the transparent partition plate 4 is provided inside the box 2 at a position above the ceiling 100a of the storage chamber 101. As shown in FIGS.

At this time, the transparent partition plate 4 is preferably 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 within the range of 3 mm or more and 40 mm or less. If the distance D is smaller than the above lower limit value, the transparent partition plate 4 will move due to the dust generated when the transparent partition plate 4 moves, which will be described later, and will accumulate between the ceiling portion 100a and the transparent partition plate 4. There is a problem that it becomes difficult to Conversely, if the distance D exceeds the above upper limit value, there is a problem such as a large amount of rubbing residue being accumulated between the transparent partition plate 4 and the ceiling portion 100a.

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

The transparent partition plate 4 has a portion 41 that exists inside the box 2 (hereinafter also abbreviated as an “internal portion”), and a portion 42 that is exposed to the outside of the box 2 through the passage opening 27 . made up of sizes.

The support rail 43 is composed of an upper surface support rail 43a and a lower surface support rail 43b, in which two plate members are arranged facing each other vertically in parallel with a predetermined interval. Since the upper surface support rail 43a and the lower surface support rail 43b are provided with the passage openings 27 in the rear plate 22 of the box 2, a gap is formed between them on the lower side of the left side plate 23 and the right side plate 24 of the box 2. It is provided so as to substantially match the height of the passage port 27 . Further, the upper surface support rail 43a and the lower surface support rail 43b are arranged in a state of being spaced apart by a dimension slightly larger than the thickness of the transparent partition plate 4. As shown in FIG.

Here, the height H of the passage port 27 is set to be at least slightly larger than the thickness of the transparent partition plate 4, but preferably the gap S of the support rails 43 as shown in FIG. set to a size larger than At this time, the passage opening 27 is formed such that the upper side 27a and the lower side 27b thereof are located outside the gap S between the support rails 43 in the vertical direction.

With this structure, the transparent partition plate 4 is less likely to rub against the passage opening 27 during its movement. It is possible to reduce the fact that it will fall into.

As shown in FIGS. 6 to 8, one end of the exposed portion 42 of the transparent partition plate 4 is provided with a grip when moving the transparent partition plate 4 in the direction E1 to pull it out and the direction E2 to push it in. A handle 46 is provided.

As shown in FIG. 7, the handle 46 is made of a member having a first bent portion 46a formed by bending the front end of a plate material upward. 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 2 when the second bent portion 46b, which is the bent end portion on the side closer to the box 2, is moved in the direction E2 in which the transparent partition plate 4 is pushed. It comes into contact with the bracket 48a and stops. Further, the handle 46 can be inserted into the protruding pin 48b provided to protrude from the bracket 48a through the through hole provided in the second bent portion 46b, and then when the transparent partition plate 4 does not need to be moved, the illustrated It is also constructed so that it can be temporarily fixed by a fixing means such as a screw.

Furthermore, as shown in FIGS. 6 and 7, one end of the portion 41 in which the transparent partition plate 4 resides is provided so as to stop at a desired position when the transparent partition plate 4 is pulled out in the direction E1. A stop member 47 is provided. The desired position is set, for example, to a position where the innermost end of the portion 41 in which the transparent partition plate 4 resides is not pulled out of the box 2 through the passage opening 27 .

The stopping member 47 is configured by using a member having a shape that protrudes upward from the upper surface 4a at one end of the portion 41 in which the transparent partition plate 4 resides and stops when it comes into contact with the upper side 27a of the passage port 27 . The stop member 47 is attached to the upper surface 4a at one end of the portion 41 in which the transparent partition plate 4 resides, by fixing means such as screws or adhesive.

As shown in FIGS. 6 and 7, the cleaning members 5 include a lower surface cleaning member 51 that comes into contact with the lower surface 4b of the transparent partition plate 4 to clean it, and an upper surface cleaning member 51 that comes into contact with the upper surface 4a of the transparent partition plate 4 to clean it. It is configured using a cleaning member 52 .

As the lower surface cleaning member 51 and the upper surface cleaning member 52, for example, a plate-shaped member made of a material such as felt (non-woven fabric) is applied.

In addition, the lower surface cleaning member 51 and the upper surface cleaning member 52 are arranged such that the end portion of the outer surface portion of the back plate 22 of the box 2 to be cleaned is located at the middle of the height H of the passage port 27 when the transparent partition plate 4 is not present. They are arranged so as to come into contact with each other at positions to block the passage opening 27 .

Further, the lower surface cleaning member 51 and the upper surface cleaning member 52 are mounted so as to pass through mounting projections (not shown) protruding outward from the rear plate 22, and then a pressing plate 55 is disposed outside the projections. Finally, a fastener 56 such as a nut is fixed to the mounting protrusion, so that it is mounted in a state of being held down by a pressing plate 55. - 特許庁

As shown in FIGS. 4 to 6, 10, etc., the box 2 has a reflecting plate that is suspended from an opening 122 for lighting installation in the housing chamber 101 from an opening 122 for installing lighting. 28 are provided.

As shown in FIGS. 4 to 6 and 9, the reflector 28 includes a flat first reflector 28a extending downward from the lower end of the back plate 22 of the box 2, and a left side of the box 2. It is configured as a member having a flat second reflector 28b extending downward from the lower end of the face plate 23 and a flat third reflector 28c extending downward from the lower end of the right side plate 24 of the box 2. . That is, the reflecting plate 28 is positioned below each of the rear plate 22, the left side plate 23, and the right side plate 24 of the box 2, and has a shape surrounding the three surfaces. One surface on the side and the surface immediately below surrounded by the above three surfaces are open.

In Embodiment 1, as shown in FIG. 6 , the opening 122 for lighting installation has a relationship in which the front-rear dimension 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, respectively. In addition, 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 housing chamber 101 (FIG. 9).

<Installation and use of lighting device>
This lighting device 1A is used by being installed in an opening 122 for lighting installation in the ceiling 100a of the crop dryer 100, as shown in FIGS.

First, as shown in FIG. 9B, for example, the lighting installation opening 122 according to Embodiment 1 is located at one of the four corners of the rectangular ceiling 100a, and is visible through the side wall surface 101a of the storage chamber 101. It is provided as a rectangular opening that is slightly inclined to face the window 117 .

For this reason, as shown in FIGS. 4, 6, 10, etc., the lighting device 1A has the reflecting plate 28 inserted through the lighting installation opening 122 to exist inside the storage chamber 101, and the box The bent portions 21a, 22a, 23a, and 24a of the side plates 21, 22, 23, and 24 of the body 2 are attached to the ceiling portion 100a around the opening 122. As shown in FIG. The box 2 at this time is fixed to the ceiling part 100a by fixing means such as screws. Also, 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 .

In addition, the lighting device 1A is configured so that the light-emitting device 3 can be turned on and off at any time by operating a lighting ON/OFF switch (not shown) provided on the operation panel 114, for example. . Furthermore, the illumination device 1A turns on and off the light emitting device 3 in conjunction with the operation of a predetermined operation (loading operation, circulation operation, drying operation, discharge operation, etc.) selected and instructed by operating the operation panel 114. is also configured to occur automatically.

Then, the illumination device 1A is used, for example, in the following manner during a catch-up operation.

First, when the lighting device 1A automatically turns on the light emitting device 3 by turning on the on/off switch or interlocking with the tensioning operation, the light emitting device 3 emits light as indicated by the two-dot chain line arrow in FIG. The emitted light for illumination passes through the transparent partition plate 4 from the inside of the box 2, passes through the bottom of the box 2 and the opening 122 for lighting installation in the ceiling 100a, and enters the inside of the storage 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 101a of the storage chamber 101 when the crops are not stored in the storage chamber 101. , reach the see-through 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 see-through window 117 as part of the light reflected by the inner wall surface of the storage chamber 101 when the interior of the storage chamber 101 is illuminated. stomach.

As a result, when light reaches the see-through window 117, part of the light K passes through the see-through window 117 and leaks out of the storage chamber 101, as illustrated by the two-dot chain line arrow in FIG. .

Subsequently, when the crops are staked and stored in the storage chamber 101 by the stocking operation, the interior of the storage chamber 101 is blocked by the crops from the lower one of the plurality of see-through windows 117 .

As a result, the light from the light-emitting device 3 does not reach the see-through window 117 blocked from the inside by the crops, but reaches the see-through window 117 not blocked by the crops. become.

Here, for example, it is assumed that the crops are stored up to the height of the deposition surface 200a indicated by the chain double-dashed line in FIG.

In this case, the light from the light-emitting device 3 does not reach the group of see-through windows 117b present below the height of the piled surface 200a of the crop. Therefore, almost no light K leaks out of the storage chamber 101 from the group of transparent windows 117b, and the group of transparent windows 117b is visually recognized as a dark transparent window 117b. On the other hand, the light from the light-emitting device 3 reaches the group of see-through windows 117a above the height of the crop deposition surface 200a. Therefore, the light K leaking out of the housing chamber 101 exists from the group of transparent windows 117a, and the group of transparent windows 117a is visually recognized as a bright transparent window 117a.

Therefore, in the crop dryer 100 to which the illumination device 1A is attached, the highest see-through window 117b visible as the dark see-through window 117b in the housing chamber 101 (or the dark see-through window 117b one below the bright see-through window 117a) It can be seen that the crops are stored up to the height of the see-through window 117a).

<Action and effect of lighting device>
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 a stake-in operation is performed, and the storage chamber 101 becomes empty. It floats so as to diffuse through space. Also, part of the dust may move closer to the lighting device 1A.

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

Therefore, according to the illumination device 1A, it is possible to prevent the dust from adhering to the light-emitting device 3 mounted inside the box 2 and lowering the brightness of the illumination. As a result, it becomes difficult for dust to adhere to the light-emitting device 3 to visually confirm the amount of crops contained in the containing chamber 101 of the crop dryer 100 through the see-through window 117 .

In addition, since the lighting device 1A has the transparent partition plate 4 positioned above the ceiling portion 100a inside the box 2, the transparent partition plate 4 is positioned at the same position (height) as the ceiling portion 100a. Even if the dust moves along the ceiling part 100a and approaches it, it is less likely that the dust will reach the transparent partition plate 4 directly and will not adhere to the transparent partition plate 4 as compared with the case where the dust is arranged. . Also, in this case, it becomes easier to avoid contact of the crops housed in the housing chamber 101 with the transparent partition plate 4 .

Moreover, since the illuminating device 1A is provided with the reflecting plate 28 that hangs down inside the housing chamber 101 on the bottom surface of the box 2, the illuminating device 1A is more efficient than the case where the reflecting plate 28 is not provided. Dust approaching is blocked by the reflecting plate 28 or changed course, so that the dust is less likely to reach the transparent partition plate 4 directly and is less likely to adhere to the transparent partition plate 4.例文帳に追加

Therefore, in the illumination 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. prevented from declining.

Further, in the illumination device 1A, the portion 41 where the transparent partition plate 4 exists inside the box 2 can be moved to the outside of the box 2. A cleaning member 5 ( 51 , 52 ) is provided for contacting and cleaning the passage port 27 .

For this reason, for example, when the transparent partition plate 4 is dirty due to adhesion of dust or the like, as shown in FIG. When the cleaning member 5 (51, 52) contacts the upper and lower surfaces 4a, 4b of the cleaning member 5 (51, 52), the dust is removed and cleaned. As a result, the transparent partition plate 4 is prevented from deteriorating in its translucency due to adhesion of dust.

Therefore, in the illumination device 1A, it is possible to prevent the transmittance of the light from the light-emitting device 3 through the transparent partition plate 4 from being reduced due to adhesion of dust to the transparent partition plate 4. This also contributes to the brightness of the illumination. This prevents a decrease in slackness.

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

At this time, the transparent partition plate 4 may need only to be moved in the pull-out direction E1 and in the push-in direction E2 only once. Sometimes, the back-and-forth movement is performed multiple times. In any case, according to this illumination device 1A, the cleaning work of moving the transparent partition plate 4 for cleaning can be easily performed outside the box 2. As shown in FIG.

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

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

Unlike the lighting device 1A according to Embodiment 1, the lighting device 1B includes a moving device 6 for moving the transparent partition plate 4 with respect to the box 2 and a first operation means 69 for operating the moving device 6. and are newly added.

The moving device 6 is a device comprising 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 using, for example, a solenoid.

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

The first operation means 69 is provided as a part of the operation function on a part of the operation panel 114 provided at the bottom of the crop dryer 100 . The first operating means 69 is composed of, for example, a movement switch for turning on/off the operation of the drive section 6a in the movement device 6. As shown in FIG. 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 driving section 6a of the moving device 6 through wiring 6c for supplying power and transmitting control signals.

According to the lighting device 1B having the moving device 6 and the first operating means 69, when performing the cleaning work of moving the transparent partition plate 4 and cleaning with the cleaning member 5, the worker moves the crop dryer 100. It is not necessary to climb to the ceiling part 100a, and the operation can be easily performed by operating the first operating means 69 arranged in the lower part of the crop dryer 100. FIG.

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

The moving operation of the transparent partition plate 4 by the moving device 6 is automatically performed at the time when a movement such as a staking operation is finished, instead of being performed when instructed by the operation of the first operating means 69. It may be configured as

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

A moving device 61 shown in FIG. 12 has a drive section 6a and a transmission section 6b by applying a rage tongue type link mechanism 62. As shown in FIG. Also, the first operating means 69 in this moving device 61 is composed of an operating lever 69 a for inputting power to the link mechanism 62 .

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

The link mechanism 62 connects the free end of a link 62f as a driving link to one end of a swing bar 63b that swings about a shaft 63a provided on the main body of the moving device 61 via a connecting means 63c such as a wire. connected.

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

Further, the link mechanism 62 has a pressing coil spring 64 between the main body of the moving device 61 and the lower projection 46a of the handle 46 of the transparent partition plate 4. As shown in FIG.

The pressing coil spring 64 is a spring that generates a force to push the transparent partition plate 4 into the box 2 in the direction E2. It is a spring that functions to increase the force pushing the transparent partition plate 4 in the direction E2.

In addition to the coil spring 64, the link mechanism 62 has a coil spring 62h arranged between the free end of the link 62c and the ceiling portion 100a to elastically push the free end of the link 62c upward. It may be configured to keep the state.

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

At this time, as shown in FIG. 12(A), 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 internal portion 41 is kept in a state of being housed inside the box 2 . Further, at this time, the link mechanism 62 is extended as a whole corresponding to the position of the shaft 62a on the handle 46 of the transparent partition plate 4. As shown in FIG.

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

That is, at this time, as shown in FIG. 12(B), the operator operates the operating lever 69a so as to lower it in the downward direction indicated by the arrow J. As a result, the rocking bar 63b of the moving device 61 rocks around the shaft 63a to the right in the figure, so that one end of the rocking bar 63b is attached to the link mechanism 62 via the coupling means 63d. The end of the link 62f is lifted, and the entire link 62f is swung around the moving shaft 62e to turn to the left. 12(B), the link mechanism 62 moves toward the side where the rocking bar 63b is located, and is folded as a whole.

As a result, the transparent partition plate 4 in the illumination device 1B is moved in the direction E1 in which it is 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 are brought into contact with the cleaning members 51 and 52 outside the passage opening 27 of the box 2 and cleaned.

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

Therefore, the moving device 61 does not require an operation such as lifting the operation lever 69a when moving the transparent partition plate 4 in the pushing direction E2, thereby reducing labor during the cleaning work. Further, when the coil spring 62h is arranged, when the operation lever 69a is released from the lowered state, the coil spring 62h is restored from the contracted state (FIG. 12(B)) to the restored state (FIG. 12(A)). Since the link 62g is returned to its original position at this point, the transparent partition plate 4 is also moved in the pushing direction E2, and the operation such as lifting the operation lever 69a becomes unnecessary.

A moving device 65 shown in FIG. 13 includes a driving portion 6a and a transmitting portion 6b by applying a wire driving mechanism 67 for moving a wire 66 attached to the transparent partition plate 4. As shown in FIG. 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 .

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

The wire driving mechanism 67 in the moving device 65 winds and holds the wire 66 approximately in the middle thereof around a rotating drum 67a, and rotates the rotating drum 67a in a desired direction in accordance with the direction in which the transparent partition plate 4 is moved. It is a mechanism for moving the wire 66 in a desired direction by rotating it with a drive source such as a motor. The wire drive mechanism 67 is connected to the first operating means 69 by a connection wiring 67b for supplying power and transmitting control signals.

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 direction in which the transparent partition plate 4 is moved.

In the illumination device 1B using the moving device 65 as the moving device 6, the operation of the first operating means 69 and the operation of the wire driving mechanism 67 are unnecessary when the cleaning work by moving the transparent partition plate 4 is unnecessary.

At this time, as shown in FIG. 13(A), the portion 41 in which the transparent partition plate 4 of the illumination device 1B resides is housed inside the box 2 due to the initially set movement position of the wire 66. kept. That is, in this moving device 65, the position of the wire 66 is fixed at the position when the rotating drum 67a in the wire driving mechanism 67 stops rotating, and when the wire 66 does not move, the transparent partition plate 4 is also stopped. It is designed to be preserved.

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

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 to the right as indicated by the arrow. As a result, the wire 66 wound around the rotating drum 67a of the wire drive mechanism 67 is moved such that the other end 66b moves in the direction E1 in which the transparent partition plate 4 is pulled out. At this time, the one end 66a of the wire 66 is also moved by the same distance in the direction E1 in which the transparent partition plate 4 is pulled out.

As a result, the transparent partition plate 4 in the illumination device 1B is moved in the drawn-out direction E1 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 are brought into contact with the cleaning members 51 and 52 outside the passage opening 27 of the box 2 and cleaned.

Also, as shown in FIG. 13(A), the pulled-out transparent partition plate 4 is operated by the worker to rotate the rotating drum 67a of the wire driving mechanism 67 to the left as indicated by the arrow with the first operating means 69. By doing so, the movement of the wire 66 causes the transparent partition plate 4 to move in the direction E2 in which it is pushed.

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

This lighting device 1D is the same as the lighting device 1B according to Embodiment 2 except that it is provided with a displacement means 8 for displacing the light emitting device 3 and a second operation means 89 for operating the displacement means 8. It consists of:

As shown in FIG. 17(A), the displacement means 8 in the illumination device 1D swings the light emitting device 3 in the interior of the box 2 substantially horizontally as indicated by the double arrow P with the support shaft 81a as the fulcrum. and at least one of a lifting portion 82 that reciprocates the supporting shaft 81a that supports the light emitting device 3 so as to vertically move it up and down as indicated by the double arrow Q, and the swinging portion 81 and the lifting portion 82. and a drive unit 83 for driving the .

Of these, the swinging portion 81 is configured by, for example, a mechanism that rotates the support shaft 81a in forward and reverse directions within a required angle range. The lifting section 82 is configured by, for example, a mechanism that vertically moves a support member 82a that supports the support shaft 81a along a guide groove 82b that extends vertically. Further, the drive unit 83 is configured using an electric motor, a gear mechanism, etc. that supply power necessary for swinging in the swinging unit 81 and raising and lowering in the lifting unit 82 .

Further, the rocking movement by the rocking part 81 and the vertical movement by the lifting part 82 are configured to be performed at predetermined required speeds and intervals.

As shown in FIG. 17(B), the second operating means 89 is provided as part of the operation function on a part of the operation panel 114 provided in the lower part of the crop dryer 100 . The second operating means 89 is, for example, a displacement switch that turns on and off at least one of the swinging portion 81 and the lifting portion 82 of the displacement means 8 . The second operating means 89 is connected to the driving portion 83 of the displacement means 8 by wiring 83c for supplying electric power and transmitting control signals.

In the illumination device 1D having the displacement means 8 and the second operation means 89, when the driving part 83 of the displacement means 8 is operated by the second operation means 89, the swinging part 81 or the lifting part 82 is operated, as shown in FIG. As shown in A), the luminaire 3 swings inside the box 2 as indicated by the double arrow P, or moves up and down as indicated by the double arrow Q. As shown in FIG. 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 fluctuate horizontally or vertically.

Therefore, according to the illumination device 1D, since the light emitting device 3 is displaced in the horizontal direction or the vertical direction by the displacement means 8, the amount of light leaking to the outside from the see-through window 117 in the housing chamber 101 is reduced compared to the case where the light emitting device is not displaced.

[Modification]
The present invention is not limited to the contents exemplified in Embodiments 1 to 4, and various modifications are possible within the scope of not changing the gist of each invention described in the claims. It also includes modifications such as those listed in .

In Embodiment 1, the case where the transparent partition plate 4 is provided movably with respect to the box body 2 and the cleaning member 5 that contacts and cleans the transparent partition plate 4 is provided in the lighting device 1A is exemplified. However, the illumination device 1A can be configured such that the transparent partition plate 4 is provided without moving and the cleaning member 5 is not provided.

In the illumination device 1A configured in this way, cleaning becomes impossible by moving the transparent partition plate 4 with respect to the box 2 and bringing it into contact with the cleaning member 5. The transparent partition plate 4 can prevent it from adhering to the light-emitting device 3 mounted inside the body 2. - 特許庁

Embodiments 1 and 2 exemplify the case where a pair of cleaning members 51 and 52 that come into contact with the upper surface 4a and the lower surface 4b of the transparent partition plate 4 are provided as the cleaning member 5 in the lighting devices 1A and 1B. However, in the illumination devices 1A and 1B, only one cleaning member 51 that contacts the lower surface 4b of the transparent partition plate 4 may be provided as the cleaning member 5. FIG.

In the illumination devices 1A and 1B configured in this manner, only the lower surface 4b is cleaned by the cleaning member 51 and the upper surface 4a is not cleaned when the transparent partition plate 4 is moved in the directions of the arrows E1 and E2. Since the dust that is collected tends to adhere to the lower surface 4b facing the interior of the storage chamber 101, it is sufficient to at least clean the lower surface 4b.

In Embodiment 3, the structure which blows air to the lower surface 4b of the transparent partition plate 4 was illustrated as the air injection member 7 in the illuminating device 1C. However, in the lighting device 1</b>C, as the air injection member 7 , an air injection member configured to blow air onto both the upper surface 4 a and the lower surface 4 b of the transparent partition plate 4 may be used.

In the illumination 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. In addition, when air is also blown onto the upper surface 4a of the transparent partition plate 4 by the air injection member 7, it is avoided that the blown air stays inside the box 2 and adheres dust to the light emitting device 3. From these points of view, for example, the box 2 may be provided with an exhaust port, or the box 2 may be provided with exhaust means for sucking and discharging the air inside the box 2 above the transparent partition plate 4 .

In the fourth embodiment, the case where the displacement means 8 and the second operation means 89 are applied to the illumination device 1B according to the second embodiment (which actually includes the illumination device 1D according to the fourth embodiment) has been described. , the displacement means 8 and the second operation means 89 can be similarly applied to the illumination device 1A according to the first embodiment and the illumination device 1C according to the third embodiment.

Further, in Embodiments 1 and 2, as a configuration in which the transparent partition plate 4 is movable, a configuration example in which the transparent partition plate 4 is linearly reciprocated in the directions 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 employed.

For example, as shown in FIG. 18, the transparent partition plate 4 is arranged inside the box 2 as indicated by arrows R1 and R2 with support shafts 49 provided at one of the four corners of the rectangular parallelepiped box 2 as fulcrums. A mounting structure can be employed that rotates to move outward from. R1 indicates the direction in which the transparent partition plate 4 is exposed, and R2 indicates the direction in which the transparent partition plate 4 is retracted.

In this case, passage openings 29a and 29b through which the transparent partition plate 4 passes are provided on two side surfaces of the box 2, and the cleaning member 5 protrudes into the passage openings 29a and 29b at least below the passage openings 29a and 29b. The lower surface cleaning member 54 is provided in such a state as to do so. As for the cleaning member 5, it is preferable to provide a pair of upper and lower cleaning members arranged so as to contact each other at an intermediate height between the passage openings 29a and 29b. Further, inside the box 2, a support rail 43 is provided which is substantially the same as the support rail 43 in the illumination device 1A for supporting the portion 41 in which the transparent partition plate 4 is contained.

In the transparent partition plate 4 having this configuration, when the cleaning operation is required, the support shaft 49 is used as a fulcrum to rotate in both directions indicated by arrows R1 and R2. At this time, at least the lower surface 4b of the transparent partition plate 4 is cleaned by contacting and passing through the lower surface cleaning member 54 .
