DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for cutting and harvesting stems of tobacco stems, which enables a process from cutting to drying from ridges to drying with high working efficiency and continuously. About technology.

[0002]

BACKGROUND OF THE INVENTION Native and Burley tobacco harvesting involves harvesting more than 20 tobacco leaves from a single tobacco stem. In a typical harvesting method, first, about six lower leaves are peeled off from the trunk, which is leaf-knitted for drying after harvesting. The remaining upper leaves are harvested by a harvesting method called trunk cutting. That is, the tobacco stem is cut off with a sickle while about 14 leaves are attached to the stem, and then the tobacco stem is collected with the tobacco leaves attached and suspended in a drying facility.

[0003] In addition, there is also a system for loading, transporting, and hanging in a drying facility at the same time as mowing (for example, Japanese Patent Publication No. 6-2006, Japanese Utility Model Publication No. 7-48).
022). In this technique, moving a trunk loaded on the bed of a work machine to a transport vehicle is very heavy and heavy labor, and the trunk transported by this transport vehicle is piled up and dried. The work was not considered until the work of hooking the wire, the wire, or the rope stretched in the facility was simplified, and the drying work was very heavy labor and took a lot of time.

Further, in order to hang the mown tobacco stem into a drying facility, the stem of the stem is pierced into an elongated rod-shaped thing, a so-called stick, and suspended from the hanging frame of the drying facility via the stick. . There has been proposed one in which the work of piercing the tobacco stem into a walking stick is performed mechanically. For example, Japanese Patent Publication No. Sho 63-66507 discloses a structure in which a predetermined number of tobacco stems are fixed on a base at predetermined intervals, and sticks are pierced into the base from the side. Japanese Patent Publication No. 55-46154 discloses an arrangement in which a stick is fixed on a base in advance, and the stem of the tobacco stem is pierced from the side of the fixed stick.

However, the aforementioned Japanese Patent Publication No. Sho 6
In the technique described in Japanese Patent Publication No. 3-66507, it is assumed that the apparatus is used in a specific workplace, and it is necessary to transport the tobacco stem cut in the field to the workplace, and the process from cutting to drying is continuously performed. Could not be done. Although the technology described in Japanese Patent Publication No. 55-46154 can be miniaturized, the stick into which the required number of tobacco stems are stabbed is quite heavy, and it is difficult to carry it to the drying facility. It is difficult to continuously perform the processing from cutting to drying.

According to the present invention, in order to solve the above-mentioned inconvenience occurring from the cutting of a stem-cut tobacco stem to the drying process, the tobacco stem is cut and introduced in a field, and a short working time is required on the spot. The number of sticks can be easily pierced on the stick, and furthermore, the sticks with the tobacco stems made in that way can be easily carried into a drying facility at the same time in a large number, so that from cutting to drying can be performed. It is an object of the present invention to provide a trunk-cutting tobacco-harvesting vehicle that can make the work process continuous and simple and can greatly reduce the work time.

Each is pivotally connected. A compression spring 35 is elastically fitted to the rods 32 and 32 and is urged rightward.
(Spike claws 37, 37). In this way, the tobacco stem can be reliably held irrespective of the stem diameter, and the spike claws 37 pierce the tobacco stem so that the holding position does not shift, and the tobacco stem can be conveyed without changing its posture.

Further, a driving sprocket 26 for winding and supporting the rear part of the transport chain 24 is disposed so as to be inclined so as to be lower in the direction of the recovery gantry 5. That is, the axis O1 of the drive sprocket 26 is in the vertical direction (the main frame 23).
Angle to the left side (in the direction perpendicular to the
Leaning. This angle θ is most preferably about 90 degrees so that the tobacco trunk can be placed horizontally on the collection platform 5 described later. However, with such a configuration, the transport chain 24 is twisted by 90 degrees and hinders transport, In addition, the spike claw 37
Since it takes 37, there is a possibility that the posture of the tobacco stem may be lost before placing the tobacco stem. Therefore, in the present invention, the angle is such that the tobacco stem falls down to the collection stand 5 side by its own weight at the transport end position. By providing this tilt angle θ, the transport surface is tilted to the left as it moves backward,
The tobacco stem after harvesting is tilted to the left (toward the collection gantry 5) at the rear position where it is pinched and conveyed, and when falling at the end, the tobacco trunk is laid down in a sideways position with the base side to the right.
It is collected above.

As shown in FIG. 4, a guide plate 39 is provided at the rear of a cover that covers the upper surface of the transport chain 24, covers the hydraulic drive motor 29 and the like, and the tobacco trunk is formed by the left side surface of the guide plate 39. I am trying not to fall to the right side. Further, a guide plate 41 is provided at the rear of the cover that covers the upper surface of the holding rod 25, so that the tobacco trunk does not fall on the rear end of the holding rod 25, and the tobacco stem falls smoothly onto the collection gantry 5 without falling forward. I am trying to become.
The drive sprocket 26 is driven by a hydraulic drive motor 29 disposed at the rear upper portion of the trunk cutting and conveying device 4 via a transmission unit including a sprocket, a chain, and the like. The hydraulic drive motor 29 is pressure-fed from the hydraulic pump 19a. Driven by the operating oil.

The front portion of the trunk cutting and conveying device 4 is located substantially at the center of the left and right sides of the vehicle body 1 to cut the root of the tobacco trunk, and the rear portion is closer to the left and right than the left and right center of the vehicle body 1. It is eccentric and, in the present embodiment, is eccentric to the right in the traveling direction and is conveyed diagonally to the right and rearward and upward. A collection gantry 5 is disposed on the left side of the rear end of the trunk cutting and conveying device 4.
That is, since the vehicle body 1 runs across the ridges across the ridges,
It is desirable that the guiding portion 100 is located at the center in the left and right direction. By transporting the base portion to the upper side on one side (right side), the tobacco trunk that has been turned down can be placed and placed substantially within the left and right widths of the vehicle body 1. Then, the root portion can be brought closer to the trunk supply portion 104 of the stick piercing device 7 described later, so that the lifting distance and the moving distance are short, and the work of the next step is easy to perform. However, it is also possible to adopt a configuration in which the tobacco stem is transported in the left and right opposite directions. The collection gantry 5 is placed on the upper part of the front frame 3 in the horizontal direction, so that the position of the collection gantry 5 can be adjusted back and forth so as to be fixed. The right end of the collection gantry 5 is located substantially below the rear end of the trunk cutting and conveying device 4, and the left and right lengths are set to a length that can sufficiently place the tobacco stem.

In this way, at the rear position of the trunk cutting and conveying device 4, the collection rack 5
Is adjusted to the front and rear, and the stem-cutting tobacco-harvesting vehicle is run across the ridge, the cutting height is adjusted by the gauge frame 51, and the splitter 55
The tobacco trunk is guided between 55, and the root of the tobacco trunk is supported by guide rods 54 and cut at the cutting portion 58. Then, the tobacco stem is pierced by the spike claws 37, pressed by the holding rods 25, 25 and conveyed rearward and upward while clamping the root portion, and conveyed while being gradually inclined leftward at the rear upper part. The trunk is placed on the collection stand 5.

Next, the stick piercing device 7 will be described. As shown in FIG. 7 and FIG.
A frame frame 44 is laid horizontally on the front upper portion, a driven sprocket 45 is supported on the right side of the frame frame 44, and a driving sprocket 46 is supported on the left side. A space between the driven sprocket 45 and the driving sprocket 46 is provided. Is wound around a transport chain 47 formed of an endless belt. A rotary drive type hydraulic motor 72 as an actuator is disposed above or below the drive sprocket 46 so that the transport chain 47 can be driven to rotate. However, it is sufficient that the hydraulic motor 72 is disposed inside the transport chain 47, and power may be transmitted from the output shaft of the hydraulic motor 72 to the drive sprocket 46 via a speed reduction mechanism. A claw member protrudes from the outer periphery of the transport chain 47 at a predetermined interval, and the claw member is constituted by a trunk feed claw 48 and a stick supporting claw 49.
The transport chain 47 may be a belt, in which case pulleys are used instead of the sprockets 45 and 46.

The nails are fixed at equal pitches (the interval between the tobacco stems piercing the stick 8), and the stem feed nails 48 are formed in a U-shape when viewed from the side. Forty-eight closed surfaces are fixed. The stem feed claw 48
Is formed with a concave hook groove 48a in a plan view on the front side in the traveling direction (the direction of the arrow a in FIG. 7), and the upper and lower two hook grooves 48a guide the tobacco stem so as not to shift back and forth. . Further, the side of the main feed claw 48 on which the transport chain 47 is attached is a guide plate 65 fixed to the frame 44.
65 guides the tobacco stem so as to eliminate the downward displacement caused by the load. Further, a stick supporting claw 49 protrudes from the inner surface of the stem feed claw 48, and the tip of the stick supporting claw 49 extends to the position of the hook groove 48a. A cut 49a is formed so that the walking stick 8 can be placed.

A support member for the stick 8 is disposed on each of the left and right sides of the frame 44.
A clip 60 is fixedly provided as a cane rear end fixing means in accordance with the height of the cane support claw 49.
Reference numeral 0 indicates that the end of the walking stick 8 can be fitted and pinched from the front. Further, a plate-shaped stick stopper 68 is provided to protrude forward from the left side of the frame frame 44,
The end of the stick 8 is prevented from hitting when piercing the tobacco stem.

Further, a right holding member for the walking stick 8 is provided at a right end portion of the frame 44, and the holding member is configured to be releasable, and an arm 61 is provided so as to be vertically rotatable, and a front end of the arm 61 is provided. A support rod 62 is protruded rightward in the horizontal direction from the portion, and the support rod 62 is formed in an L-shape when viewed from the front, and rotatably supports a grooved roller 63 at the lower end of the support rod 62. The other end of the arm 61 is urged by a spring (not shown), and the grooved roller 63 is pressed against the side of the stick supporting claws 49. On the other hand, the rear end of the arm 61 is connected via a wire 66 to a pedal 67 disposed on the front left side of the bed 2.

In such a configuration, the pedal 67
When the stepping operation is performed, the grooved roller 63 is moved together with the arm 61.
Is rotated upward to be opened, and the clip 6 is held while the left side of the stick 8 is in contact with the stick stopper 68.
0, and the middle part of the stick 8 is an L-shaped notch 49a.
When the pedal 67 is released and the stepping operation of the pedal 67 is released, the grooved roller 63 is rotated and the stick 8 is pressed by the urging force of the spring.
The right side of is held down. At one end (right end) of the stick 8, an arrowhead (spear) formed in a pointed shape so as to make it easier to pierce the tobacco stem is attached. Has been crowned.

The right side of the frame 44 is a trunk supply portion 104, and an inverted L-shaped trunk contact plate 69 is provided on the front of the frame 44 so as to protrude therefrom. To the top of the trunk so that the height is even,
This position is referred to as a trunk supply unit 104. A stem detection switch 70 as a means for detecting a tobacco stem is disposed in the upper and lower portions of the stem contact plate 69, and a detection plate 71 is pivotally supported on the upper part of the frame 44 below the stem detection switch 70.
The detection plate 71 is held in an inclined shape. Therefore,
When the tobacco stem is lifted toward the stem contact plate 69,
The base of the tobacco stem is rotated by hitting the detection plate 71, the stem detection switch 70 is turned on, the electromagnetic valve is driven via a control circuit (not shown), and the hydraulic drive motor 72 can be driven. The hydraulic drive motor 7
The drive sprocket 46 is fixed to the output shaft 2 to drive the transport chain 47.

In order to stop the hydraulic drive motor 72, a stop switch 74 as stop position detecting means is arranged in the rotation locus of the trunk feed claw 48. In this embodiment, a stay 73 is protruded from the rear upper portion of the frame 44,
A stop switch 74 is fixed to the stay 73. Accordingly, the hydraulic drive motor 72 is driven to move the stem feed claw 48, and when the next stem feed claw 48 hits the stop switch 74, the hydraulic drive motor 72 stops. That is, the stem feed claw 48 moves one pitch and always stops at the standby position.

Further, as shown in FIG. 1, a manual switch 88 is disposed at the front of the storage frame 6, and the manual switch 88 is provided.
Accordingly, the hydraulic drive motor 72 can be driven regardless of the trunk detection switch 70, and can be driven until the stop switch 74 is turned off.

With the construction of the stick piercing device 6 in this manner, the stick 8 is provided in front of the trunk feeding claws 48.
Is set, and the operator lifts the tobacco trunk placed on the collection platform 5 and lifts it to abut the stem abutment plate 69. When the detection plate 71 rotates, the trunk detection switch is turned on. 70 is turned on and the hydraulic drive motor 7
2 is driven. With this drive, the stem feed claw 48 moves to the left, the tobacco stem enters the upper and lower hook grooves 48a, 48a and is pushed while being guided, and the central portion of the tobacco stem pierces the arrowhead at the tip of the walking stick 8. Then, the stop switch 74 stops when the stem feed claw 48 has moved by one pitch. At the time of piercing, the stick 8 is received by the stick stopper 68. The stick 8 is pressed by the grooved roller 63 urged by a spring, and the stick 8 does not come off.

Next, when the tobacco stem is lifted and brought into contact with the stem contact plate 69, the stem feed claw 48 moves again,
The tobacco stem that has been pierced into the arrowhead and has already been pierced can be moved on the walking stick 8 one pitch at a time. Repeat this operation to stick the tobacco stems one after another.
And move the pierced tobacco stem one pitch at a time to the back left side. Since the grooved roller 63 is urged by a spring, the grooved roller 63 does not hinder the movement of the tobacco stem. Then, when the required number (for example, eight) of tobacco stems are pierced over the entire length of the walking stick 8,
The cigarette trunk is automatically and evenly pierced and aligned on the walking stick 8.

Thereafter, the pedal 67 is depressed to release the grooved roller 63 upward, the stick 8 is taken out, and the stick 8 is hung on the storage cart 13. Then, the stick 8 is newly taken out from the stick hopper 9 above the stick sticking device 7 and set, and the above operation is repeated.

When the stick piercing device 7 is configured in this manner, for example, a trunk feed claw 48 on the outer peripheral portion of the transport chain 47 via an actuator such as a cylinder for reciprocating drive.
The working speed can be increased as compared with a configuration in which the transport chain 47 is driven by pressing the same. That is, in the configuration in which the transport chain 47 is driven at a predetermined distance by reciprocating drive of a cylinder or the like, the transport rod 47 is driven by extending the rod of the cylinder, and at the same time, the tobacco stem is directly pushed to pierce the tip of the stick 8 instantaneously. A force can be applied, but at this time, a predetermined position of the tip of the stick 8 to be inserted into the stick 8 is closed with a rod of a cylinder or the like, and the tobacco stem is supplied to the predetermined position until the rod is completely contracted. And to wait for the next tobacco stem to stick, it was necessary to wait for the cylinder rod to fully retract. For this purpose, the drive chain sprocket 46 is driven by a hydraulic motor 72 disposed inside the transfer chain 47 so as to drive the transfer chain 47, so that a predetermined position where the tobacco stem is to be inserted into the walking stick 8 is always opened. The stem can be supplied and the hydraulic drive motor 72 can be driven to pierce the cane, and the tobacco stem can be supplied one after another to continuously pierce the cane 8, thereby improving the work speed of piercing the cane. You can do it.

The stick hopper 9 is mounted on the frame 4
