Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a bulb removing device for a cut flower, which leaves the rhizome in the bulb and removes the bulb in order to cut bulb plants such as tulips and lilies.

[Prior Art] Generally, when a bulb plant such as a tulip is used as a cut flower,
It is preferable to leave the rhizome inside the bulb and remove the bulb attached to this rhizome rather than cutting the stem above the bulb, and the one with the long stem has a higher commercial value. is there.

Therefore, conventionally, when shipping cut flowers, the bulb portion is removed by using a cutter or the like.

[Problems to be Solved by the Invention] In the above-mentioned prior art, since the work of removing the bulb portion with a cutter or the like is performed by input, the work efficiency is poor, and it is difficult to continue the work for a long time. Moreover, there is a risk that the cut flower may be cut by a cutter or the like into the rhizome in the bulb portion, and the commercial value of the cut flower may be reduced.

The present invention has been made based on the above circumstances, and an object of the present invention is to provide a bulb removing device for cut flowers, which can easily remove the bulb portion while leaving the rhizome and save labor.

[Means for Solving the Problems] The present invention is directed to a pair of rollers having circumferential surfaces facing each other with a gap, a recess formed on the circumferential surface of at least one of the rollers, and rotation of the rollers. And a driving device.

[Operation] The bulb portion inserted between the pair of rotating rollers is split by the recess for bulb embedding, and the bulb portion can be removed from the stem.

Is provided with an extending portion 24 extending below the bearing base 10. The extended portion 24 is slidably inserted into the elongated hole 25 for the extended portion 24 formed in the bearing base 10 in the left-right direction, and penetrates the extended portion 24 in the left-right direction. Female thread part 24
A is provided. Further, the other side of the operating shafts 26, 27 having one end formed with a male screw portion 24B screwed to the female screw portion 24A is provided so as to project from the side surface of the machine frame 1, and the operating shaft
Chains are attached to splines 28 and 29 that are fixed to 26 and 27, respectively.
30 is stretched. A handle 31 is attached to the operation shaft 27.
Is stuck.

The motor 2, the V belt 7, the drive shaft 11, the driven shaft 16 and the like constitute a rotary drive device 32. Further, the handle 31, the operation shafts 26, 27, and the like constitute an adjusting device 33 for adjusting a roller interval described later.

Reference numeral 34 denotes a cylindrical drive-side roller made of rubber or the like fixed to the front end of the drive shaft 11.
34 and a subterranean stem 38 such as tulip, with an interval L,
A cylindrical driven roller 35 made of rubber or the like is fixed to the front end of the driven shaft 16 with their peripheral surfaces 34A, 35A facing each other. Further, a concave portion 36 for embedding the bulb is formed on the peripheral surface 35A of the roller 35 on the driven side. The peripheral surface 34
A and the inside of the recess 36 are formed to be narrower than the bulb.

Next, the operation of the above configuration will be described.

When a switch (not shown) is operated to energize the motor 2,
The rotation of the motor 2 is transmitted to the drive shaft 11 via the V-belt 7, and the drive gear 13 and the driven gear provided on the drive shaft 11
The driven shaft 16 rotates by meshing with 17. Then, the driving-side roller 34 rotates clockwise, and the driven-side roller 35 rotates counterclockwise faster than the driving-side roller 34 in inverse proportion to the diameters of the drive gear 13 and the driven gear 17.

When the bulb portion 37 attached to the stem is inserted from above as shown in FIG. 5 (A) between the pair of rollers 34 and 35 rotating in this way, the bulb portion 37 is cracked by being pressed between the rollers 34 and 35.

The male screw portion 24B changes the screwing position with the female screw portion 24A provided in the extending portion 24 of the bearings 18, 19 and changes the position of the driven shaft 16 in the left-right direction, so that the distance between the pair of rollers 34, 35 is increased. The distance L can be adjusted. In this embodiment, the drive gear
Since the module 13 and the driven gear 17 are set to about module 6, even if the distance between the pair of rollers 34 and 35 is adjusted by about 10 mm, both gears 1
3,17 can be in mesh.

As described above, the interval L having a substantially stalk diameter is provided between the pair of rollers 34 and 35, the recessed portion 36 for biting the bulb portion 37 is provided on the peripheral surface 35A of the roller 35, and the pair of rollers 34 and 35 are rotated. Drive 32
By providing the, it becomes possible to easily remove the bulb portion 37 from the rhizome 38, it is possible to improve the work efficiency compared to the manual work using a conventional cutter, etc. Cut flowers with high commercial value can be produced without damage.

Also, an adjusting device 33 for adjusting the distance L between the pair of rollers 34, 35.
By providing, it is possible to use for various stem diameters.

The present invention is not limited to the above-described embodiment, and a recess for bulb embedding may be provided only on the peripheral surface of the driving side roller, and a recess for bulb embedding may be provided on the peripheral surfaces of both rollers. May be provided. Alternatively, only the roller provided with the recess may be rotated. The handle may be attached to either operation shaft.
