DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a leaf picking machine for separating leaves from a trunk.

[0002]

2. Description of the Related Art Tobacco leaves have about 23 to 25 tobacco leaves per trunk.
It is called as “Leaf leaf”, “Leaf leaf”, “Upper leaf” and “Amyo leaf” Lower soil leaf,
Until the soil leaves, middle leaves and synthetic leaves, the leaves are separated from the trunk by side-crop harvesting, and they are hung and dried by a device such as a rope or a binder.

On the other hand, true leaves, upper leaves, and top leaves (about 8 to 10 leaves) are dried in a state where they are attached to the trunk, and after drying, are separated from the trunk manually (leafwood). )
Is done.

[0004]

By the way, about 240 leaf tobaccos are cultivated per are. Therefore, 1920-2400 leaf milling operations must be performed per are. In places with a large cultivated area,
There were more than one to four hectares, and in such places the labor was enormous.

[0005] It is therefore an object of the present invention to provide a leaf milling machine which saves labor in the leaf milling operation without damaging the leaves.

[0006]

According to the first aspect of the present invention, a plurality of wires are stretched on a rotatable frame to define a space allowing passage of a trunk so as to surround a rotation axis. Become.

According to the first aspect of the present invention, when a trunk with leaves is inserted into the space defined by the wires, the wires hit the leaves and tear off the leaves from the trunk. When the trunk hits the wire, the wire bends to allow the trunk to enter.

According to the second aspect of the present invention, the wire is stretched over the rotating frame via the elastic portion.

According to the second aspect of the present invention, when the leaf hits the wire, the wire bends to prevent damage to the leaf as much as possible. In addition, even when the trunk has a protruding portion and the protruding portion hits the wire, the gap between the wires easily spreads and the wire bends, so that the wire is not damaged.

[0010]

BEST MODE FOR CARRYING OUT THE INVENTION In the leaf cutter of the present invention, a space is defined by a plurality of wires stretched over a frame, the frame is rotated, a trunk is inserted into the space, and a wire is used. It is based on peeling leaves.

The space can be made triangular with three wires, quadrilateral with four wires, or n-gonal with n wires. The wire is preferably formed of a material having high toughness, but is not particularly limited.

Preferably, the wire is connected to the frame via an elastic portion. A coil spring or the like can be used as the elastic portion. Alternatively, the wire may be formed of spring steel, and a coil may be formed near the end to form an elastic portion.

The leaf picking machine of the present invention can be applied not only to leaf tobacco but also to other things such as mulberry. The space where the trunk is inserted is the thickness of the trunk,
It is set appropriately depending on the size of the leaves and the like. For example, when used as a leaf towing machine for leaf tobacco, the distance between the wires is preferably 12 to 15 mm, and the rotation speed of the frame is preferably 100 to 300 rpm.

DESCRIPTION OF THE PREFERRED EMBODIMENTS A leaf splicing machine shown in FIG. A belt conveyor 30 that conveys the leaves to another location, and a hopper 40 that guides the leaves separated by the leaf picking section 10 onto the belt conveyor 30.
And a shooter 50 that guides the stem discharged from the leaf-mog part 10 to the side of the belt conveyor 30.

As shown in FIG. 2, the leaf splicing section 10 has a cylindrical frame 11 and a four
The frame includes a wire 12 and a guide plate 13 that covers a front opening of the frame 11.

As shown in FIG. 3, the rear portion of the frame 11 is formed in a narrowed state, whereby the small diameter cylindrical portion 1 is formed.
1a is formed. A male screw 11b is formed on the outer peripheral surface of the cylindrical portion 11a.
A female screw 11d formed at one end of the cylindrical shaft 11c is screwed into b. As shown in FIG. 4, a groove 11e is formed in the frame 11 from the front end to the outer peripheral edge, and a hole 11f is formed in the bottom surface of the terminal end of the groove 11e. Further, the peripheral wall of the frame 11 is
11 g of female screw holes are formed.

The wire 12 employs spring steel, and as shown in FIG. 4, forms a coil near the end to form an elastic portion 12a. Further, both ends of the wire 12 are bent in a U-shape to form a locking portion 12b. As shown in FIG. 2, the four wires 12 have their locking portions 12b fitted into the grooves 11e of the frame 11 and inserted into the holes 11f, respectively.
It is locked to 1. The four wires 12 thus stretched in a lattice form define a substantially square space A at the center of the front opening of the frame 11.

As shown in FIG. 2, the guide plate 13 has a hole 13b at the center of the front surface 13a and a cylindrical portion 13 at the periphery.
b. Four screw insertion holes 13d are formed in the peripheral wall of the cylindrical portion 13c.

Then, the guide plate 13 allows the cylindrical portion 13c to be fitted into the frame body 11, and the screw 14 to be inserted through the hole 13d.
It is screwed into the female screw 11d of the frame 11 and attached to the frame 11. In this state, the cylindrical portion 1 of the guide plate 13
3c covers the groove 11e of the frame body 11, and restrains the locking portion 12b of the wire 12 in the groove 11e.

The leaf-mogi part 1 thus assembled
The zero cylindrical shaft 11c is supported by the machine frame 1 via the bearing housing 15, as shown in FIG. In addition, cylindrical shaft 1
A pulley 16 is fixed to the end of 1c. On the other hand, a motor 17 is installed in the bearing housing 15, and a pulley 18 is fixed to a drive shaft of the motor 17. A belt 19 is wound between the pulleys 16 and 18.

The trunk retracting section 20 is composed of a pair of rollers 21 and 22 arranged vertically. These rollers 21 and 22 are connected to the housing 2 via bearings 23 and 24.
5 and supported by the machine frame 1 via the housing 25. The bearing 23 of the roller 21 is disposed so as to be vertically displaceable with respect to the machine frame 25, and
Urged downwards. Also, the housing 25
, A motor 27 is installed, and the motor 27 drives the roller 22. Claws 28 are provided on the peripheral surfaces of the rollers 21 and 22.
Has been planted.

The belt conveyor 30 has a belt 31 disposed below the leaf picking section 10 and the trunk retracting section 20, and is rotated in the direction of the arrow by a motor (not shown). The hopper 40 is installed on the machine frame 1, and the shooter 50 is installed between the housing 25 of the trunk retraction unit 20 and the machine frame 1.

In the above-described leaf splicer, as shown in FIG. 1, when the trunk B is inserted into the lattice space A defined by the wire 12 through the hole 13b of the rotating leaf spike portion 10. The tip of the stem B is the roller 2 of the stem retraction unit 20.
The trunk B is drawn into the leaf-groove section 10 by the rollers 21 and 22. And leaf C
Strikes the wire 12 defining the lattice space A and is separated from the trunk B.

The separated leaves C fall onto the belt 31 of the belt conveyor 30 via the hopper 40, and are carried by the belt 31. The leaves C on the belt 31 are appropriately selected by people waiting beside the belt conveyor 30 to dry.

The trunk B discharged from the trunk retraction unit 20
Are collected at an appropriate place by the shooter 50.
