Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a cutter mounting structure for a rush plant, which is capable of aligning seedlings by cutting the tips of foliage and roots of rush seedlings.

[0002]

[Prior art]

 Conventionally, in the rush seedling aligning machine, which is capable of sandwiching and transporting the rush seedlings by both upper and lower transport belts and cutting the tip ends of the foliage and the root portion of the rush seedlings by a cutter, The cutting lengths of the rush seedlings remain constant while they are fixed to the rotating shafts.

[0003]

[Problems to be solved by the device]

 Therefore, even if it is desired to change the cutting length according to the transplantation condition and the growth condition of the rush seedlings, it is impossible to do so.

[0004]

[Means for Solving the Problems]

 The present invention solves such problems and has a simple structure so that the cutting length can be easily adjusted.Therefore, both cutters for cutting the tip of the foliage of rush seedlings are installed on both rotary shafts. It is configured so that it can be moved and adjusted in the axial direction.

[0005]

[Action]

 Therefore, by moving the cutter for cutting the tip end side of the foliage of the rush and moving it in the axial direction of the rotary shaft to change the attachment, the cutter can be easily moved and adjusted to easily change the cutting length.

[0006]

【Example】

 Fig. 2 is a front view showing a part of the rush seedling aligning machine, and the rush seedlings 1 extending from the root 1b to the foliage 1a are placed on a horizontal upper surface in the body having four supporting legs 7 in the lower part. A wide lower conveyance belt 2b on which the whole can be placed is stretched, and a supply base 8 and a discharge base 9 are obliquely provided at the start side and the end side of the belt 2b, respectively. An upper conveying belt 2a, which is short and narrow in the longitudinal direction, is stretched above the belt 2b so that the foliage portion 1a of the rush seedling 1 can be conveyed and held between the belt 2b and the lower conveying belt 2b. On the upper side of the lateral side of the above, a mooring belt 10 having a protrusion 10a capable of mooring the root 1b of the rush seedling 1 is stretched.

Disc-shaped cutters 3a, 3b capable of cutting the tip side of the foliage portion 1a of the rush seedling 1 are mounted on the upper and lower sides of one side of the belts 2a, 2b, which are intermediate portions, and Disc-shaped cutters 4a and 4b capable of cutting the tip side of the root portion 1b of the rush seedling 1 are axially mounted above and below the end sides, but horizontally laid parallel to the inner sides of both belts 2a and 2b. The cutters 4a and 4b are fixed to the end portions of the rotary shaft 5 and the rotary shaft 6 with the roller 11, respectively, and the hexagonal shaft portions 5a and 6a formed on the other end sides of the rotary shafts 5 and 6 have The central hexagonal holes of the cutters 3a and 3b are respectively fitted, and both hexagonal shaft portions 5a and 6a can be brought into contact with both sides of the cutters 3a and 3b and have set bolts 12, respectively. The tool 13 is angularly fitted so that both cutters 3a and 3b can be moved and adjusted in the axial direction. To achieve.

Further, sprockets 14 and 15 are fixed to the other ends of the rotary shafts 5 and 6, respectively, and a chain 18 is mounted on the drive sprocket 17 on the side of the motor 16 and the sprocket 15 which are installed inside the machine body. Further, a chain 22 is hung from the drive sprocket 19 on the side of the motor 16 to the input sprockets 20 and 21 of both belts 2b and 2a, and the input of the sprocket 14 and the engaging belt 10 is performed coaxially with the input sprocket 21. A chain 24 is mounted on the sprocket 23.

Therefore, when the rush seedlings 1 are fed onto the lower conveyor belt 2b from the supply base 8, the rush seedlings 1 are clamped by the belts 2a and 2b and conveyed in the direction of arrow a. , The tip side of the root portion 1b of the rush seedling 1 is cut by the cutters 4a, 4b, and the tip side of the foliage portion 1a of the rush seedling 1 is cut by the cutters 3a, 3b. As shown in FIG. The seeds are cut into a predetermined length, and seedlings are aligned and discharged from the discharge table 9, but the cutters 3a and 3b are removed by loosening the set bolts 12 and moving the stoppers 13 in the axial direction. By adjusting the movement in the axial direction, the cutting length L of the rush seedling 1 can be easily changed.

FIG. 5 shows another example, in which the bearing nut 25, the cutter sleeve 26, the cutters 3 a and 3 b, and the collar 27 are fitted to the threaded portions 5 b and 6 b formed on the rotary shafts 5 and 6, and the seat 28. When the bolts 29 are attached by applying the bolts, the gap between the cutters 3a and 3b and between the cutters 4a and 4b can be adjusted, and the cutting length of the rush seedling can be adjusted.

[0011]

[Effect of device]

 Thus, according to the present invention, the cutters 3a and 3b for cutting the tip end side of the foliage portion 1a of the rush seedling 1 are moved in the axial directions of the rotary shafts 5 and 6 to be attached to the cutters 3a and 3b, respectively. The cutting length of the grass seedling 1 can be easily changed because it can be easily moved and adjusted, and the functionality of the grass seedling aligning machine can be further improved, and a simple structure can be suitably implemented. Has features.
