Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a device for adjusting the drying speed of a leaf tobacco stick suspended in a leaf tobacco drying chamber. In addition,
The term "leaf tobacco chain" used here refers to harvested tobacco leaves or stems suspended from a hanging device such as a rope, wire, cane, or hanger, and is also simply expressed as a "leaf tobacco chain."

(Prior Art) In order to adjust the leaf tobacco drying speed in air drying of indigenous or burley tobacco,
The main method used has been to hang and remove blackout curtains. With this method, it is not possible to adjust the light-shielding screen step-by-step, and the light-shielding screen must either be hung or removed. On the other hand, since the actual drying conditions vary in various environmental conditions, from times of strong sunlight to times of rain, it is necessary to be able to select an appropriate shading rate in response to these changes.

However, in the prior art, as mentioned above, such stepwise adjustment could not be performed at all.

(Problems to be Solved by the Invention) The present invention eliminates these drawbacks of the prior art, and at the same time adjusts the spacing of leaf tobacco, it also adjusts the shading rate, thereby responding to changes in various environmental conditions. Accordingly, it is an object of the present invention to provide a leaf tobacco drying speed regulating device that can adjust the drying speed of leaf tobacco so that it does not proceed too rapidly, and also so that drying does not proceed and so that stuffy leaves do not occur.

(Means for Solving the Problems) The structure of the leaf tobacco drying speed regulating device of the present invention will be explained with reference to drawings showing embodiments.
1 is a hanging frame installed in the drying room;
A pair of rails 2 are provided on opposite sides of the rail. Hanging frame 1
Pulleys 17 and 17' are respectively arranged at the four corners of. Three pulleys 17 out of four slides 17, 17'
is a double structure pulley, and the other pulley 1
7' has a single layer structure. Reference numeral 18 denotes an endless operating rope, which is hung on each of the four pulleys 17 and 17'. An end 18' of the operating rope 18 hangs from one pulley 17 and is hooked onto a drive reel 20. This operating rope 1
8 are operating rods 19, 19' of the telescopic member 3, which will be described later.
is attached to. One side of the operating rope 18 (the side that is operated in the direction of arrow A when the drive reel 20 is rotated in the direction of the arrow) is connected to the operating rod 1.
9', the other side (the side that is operated in the direction of arrow B when the drive reel 20 is rotated in the direction of the arrow) is attached to the operation rod 19 (the sixth
(see figure).

Reference numeral 3 denotes a telescopic member, which has the following structure. That is, first, the two rods 4 and 4' are overlapped in an X shape, and their overlapping points are fixed by the shaft 5 to form an X-shaped rod 6. Next, a plurality of these X-shaped rods 6 are arranged, the ends 7 and 7' of the adjacent X-shaped rods 6 are overlapped, and the overlapping points are fixed by shafts 8 and 8',
A telescopic member 3 is configured. Note that the outermost rods 4, 4' of the extensible member 3 are extended to become operating rods 19, 19'.

Reference numeral 9 denotes rollers mounted on the rail 2, and each roller 9 is attached to the telescopic member 3 via a shaft 10 at equal intervals. In the embodiment shown in FIGS. 2 and 3, the shafts 8 and 10 of the upper end 7 of each X-shaped rod 6 are integrated, and a roller 9 is attached to the upper end 7. In this embodiment, the cross-sectional shape of the rail 2 is circular, and the roller 9 mounted thereon has a circumferential surface 11 hollowed out in the shape of an arc.

12 is a hanging tool locking tool, the upper end of which is attached to the shaft 8
and 10, and the lower end is
A bent part 13 is bent toward the center of the drying chamber 1, and has a structure on which the end of a hanging tool 16 such as a rope is latched. In addition, hanging tool locking tool 1
2 is slidably held by a ring portion 14 attached to the lower end of the telescopic member 3.

A roller 9 attached to an elastic member 3 is mounted on a pair of rails 2 provided at opposing positions on both sides of the hanging frame 1, respectively, and a hanging tool 16 of a leaf tobacco chain 15 is mounted on a bent part 13 of a hanging tool locking tool 12. When the end of the leaf tobacco chain 15 is hooked, the hanger locking tool 12 becomes oblique due to the weight of the leaf tobacco chain 15, and the contact position of the roller 9 with respect to the rail 2 shifts accordingly, but the circumferential surface of the roller 9 11 is hollowed out in a circular arc shape, not only will there be no hindrance to the rotation of the roller 9, but there is also no risk that the roller 9 will come off the rail 2. The hanging tool locking device 12 of this embodiment is convenient for hanging tobacco leaves or stems using a rope, wire, or the like.

4 and 5 show other embodiments of the present invention. In this embodiment, the cross section of the rail 2 is rectangular, and a pair of rollers 9 are mounted thereon. The telescopic member 3 is attached at its lower end 7' between the pair of rollers 9 via a shaft 10, and hanger locking devices 12 are attached to both ends of the shaft 10. In this embodiment, a bending part 13 at the lower end of the hanging device locking device 12 is bent in the running direction of the rail 2, and a hanging device 16 such as a cane or a hanger is hooked onto this, and tobacco leaves or stems are hung thereon. It is hung. Note that the outermost rods 4 and 4' of the extensible member 3 are extended to form the operating rod 1.
9, 19', and the operating lobe 18 (omitted in the drawing) is attached to these operating rods 19, 19'.

Reference numeral 21 denotes a light-shielding curtain, and hooks 22 are attached to both end edges of the light-shielding curtain 21 at equal intervals. The width of this light-shielding curtain 21 is the width of the leaf tobacco hanging tool 1.
The length of the light shielding curtain 21 is slightly larger than the length of 6.
It is desirable that the length be set slightly larger than the effective maximum length of the elastic member 3.

After the leaf tobacco sticks are suspended by the hanging device locking device 12 as described above, a light-shielding curtain 21 is placed above them.
is attached by hooking the hanger 22 to the hanger locking tool 12. In this way, the light shielding curtain 21 is attached to the expandable member 3 at equally spaced attachment points.

As shown in FIG. 1, the telescopic members 3, which are telescopically operated by a single operating rope 18, can be set so that a plurality of sets can be operated simultaneously.

(Function) Next, the function of the present invention will be explained. Hanging frame 1
The telescopic member 3 is attached to the rails 2 at opposing positions on both sides of the telescopic member 3 via the rollers 9, and the leaf tobacco chain 15 is suspended from the hanging tool locking device 12 of the telescopic member 3 as described above. In order to adjust the spacing between the leaf tobacco strings 15, the driving reel 20 on which the end 18' of the operating rope 18 is hung is operated. That is, the drive reel 2
If you rotate the operating rope 18 in the direction of the arrow 0 and pull the side of the operating rope 18 to which the operating rod 19' is attached in the direction of the arrow A, the operating rope 18 is endless, so the opposite side to which the operating rod 19 is attached will be pulled in the direction of arrow B. This causes the operating rods 19, 19' of the telescopic member 3 to be drawn together,
The intervals between the leaf tobacco groups 15 are narrowed at equal intervals. If the drive reel 20 is rotated in the direction opposite to the arrow,
The operating rods 19, 19' are separated from each other, and the intervals between the leaf tobacco chains 15 are widened at equal intervals.
In addition, since the operating rods 19 and 19' are extended, the expansion and contraction operation of the expansion and contraction member 3 can be performed with a smaller force based on the lever principle.

Such an operation for adjusting the interval between the leaf tobacco rows is simultaneously an expansion and contraction operation of the light-shielding curtain 21 attached to the extensible member 3 at equally spaced attachment points. That is, when the stretchable member 3 is extended, the light-shielding curtain 21 is also expanded to achieve the original light-shielding rate of the light-shielding curtain 21, and conversely, when the stretchable member 3 is contracted, the light-shielding curtain 21 is also folded accordingly. ,
The shading rate increases.

The drying speed of leaf tobacco can be adjusted by changing the interval between leaf tobacco chains and the light shielding rate of the light shielding curtain 21. When the sunlight is extremely strong and there is a risk of rapid drying, narrow the spacing between the leaf tobacco rows and at the same time fold the light-shielding curtain 21 to increase the light-shielding rate, thereby reducing the drying speed and reliably preventing rapid drying. be able to. On the other hand, in cloudy or rainy weather, when the drying process is slow and there is a risk of stuffy leaves, the spacing between the leaf tobacco plants is widened, and at the same time, the light-shielding curtain 21 is also extended to minimize the light-shielding rate and drying progresses as much as possible. By doing so, you can prevent the formation of stuffy leaves. When it becomes necessary to adjust the drying speed according to environmental conditions or the progress of drying of the suspended leaf tobacco plants, this can be done by simply operating the operating rods 19 and 19' as described above. It is.
Moreover, since the extensible member 3 of the present invention always expands and contracts with the effective width of each X-shaped rod 6 being equal, the intervals between the suspended leaf tobacco chains 15 are necessarily equal, and the intervals between the leaf tobacco chains 15 are necessarily equal. No uneven drying occurs. Furthermore, the drying speed can be adjusted steplessly.

(Effects of the Invention) In the present invention, the load of the leaf tobacco chain and the light-shielding screen that acts on the hanger anchor is directly applied to the rail via the roller, and is hardly applied to the elastic member. Furthermore, the only resistance during the telescopic operation of the telescopic member is the rolling friction of the roller against the rail, which leads to a reduction in the strength and weight of the telescopic member. Therefore,
The expansion/contraction operation of the expansion/contraction member can be easily performed with little effort, and thereby the drying speed of the suspended leaf tobacco sticks can be adjusted as appropriate in a stepless manner. This makes it easy to adjust the drying speed to an appropriate level in response to changes in environmental conditions and the progress of the drying state of the leaf tobacco plants. In addition, the spacing between each leaf tobacco series is always maintained at equal intervals, so
It does not cause uneven drying and prevents the formation of rapidly dry leaves and stuffy leaves.
