[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a side view showing a schematic configuration of an automatic planting machine for sugar cane according to the present invention.

As shown in FIG. 1, a planting machine 11 is connected to a rear portion of a vehicle body of a traveling vehicle (tractor) 10, and a pedestal 11 a of the planting machine 11 stores a cane stalk X for planting. A stalk storage room 12 for storage is provided. The stem storage room 12 stores at least 270 to 290 planting stems X having a length of 260 mm to 290 mm and having 2 to 3 nodes X ₁ ... In the pretreatment step.

At the rear end side of the pedestal portion 11a, there is provided a stem extracting mechanism 13 for taking in the stem X for planting one by one. In the stem removing mechanism 13, a chain belt 15 is wound around a pair of upper and lower rotating drums 14, 14, a stem X is placed on the surface of the chain belt 15, and is conveyed as the chain belt 15 moves. L-shaped latch portions 16 are attached at regular intervals.

On the other hand, the floor 12 a of the stalk storage room 12 constitutes a stalk transport mechanism 22. That is, the floor surface 12a is an inclined floor surface that is gradually inclined toward the lower part of the stem removal mechanism 13, and a floor vibrating device 17 is provided on the back surface side. As shown in FIG. 5, the floor vibrating device 17 has three arms 17b projecting from the outer periphery of the rotating shaft 17a at intervals of 120 °, and the arms 17b are rotated by rotating the rotating shaft 17a. Abuts against the floor surface 12a to apply vibration to the floor surface 12a to advance the stem X toward the stem extraction mechanism 13 side.

A partition plate 18 is disposed in the stalk storage room 12 so as to face a floor surface 12a with a predetermined gap L (see FIG. 4) slightly larger than the diameter of the stalk X. Many stems X for planting are stored in the stem storage room 12 on the back side of the partition plate 18, and the stem removal mechanism 13 side of the partition plate 18 is connected to the stem L for planting via a gap L with the floor surface 12a. Since X is transported, the planting stalks are aligned and advanced one by one toward the stalk take-out mechanism 13.

The relationship between the distal end side of the floor surface 12a and the L-shaped latching portion 16 is such that, as shown in FIG. 2, convex portions 12b are provided at predetermined intervals on the distal end side of the floor surface 12a. Although not shown, the projection 12b is provided with a locking projection. Further, on the opposite side of the retaining portion 16, a concave portion 16a for inserting the convex portion 12b is provided. The projection 16b is provided with a locking projection 16c (see FIG. 3).

Therefore, the planting stem X placed on the tip side of the floor surface 12a does not fall off, and the rising latch portion 16 slips through the tip side of the floor surface 12a while falling through the floor surface. The stem X for planting placed on the tip side of 12a can be taken in.

Further, a pipe body 19 for dropping the planting stems X taken in by the stem removing mechanism 13 into the field one by one is provided outside the stem removing mechanism 13. At the opening on the upper surface of the pipe body 19, a planting stem X hung on the L-shaped hooking portion 16 of the stem take-out mechanism 13 is moved from the top as the chain belt 15 moves. Released when descending. The planting stem X discharged into the opening on the upper surface of the pipe body 19 falls in the pipe body 19 and falls into the field from the opening on the lower surface of the pipe body 19 and is planted.

The tractor 10 plows the field with the rotary 21, and as shown in FIG. 6, removes the ridge A with the bite plate 20 including the left and right plates 20 a and 20 a and the support shaft 20 b, and falls while removing the ridge A. The soil is applied to the stem X for planting that has come (see FIG. 7).

Although not shown, a guide frame slightly wider than the planting stem X is formed on the floor surface 12a, and the planting stem X is taken out while being regulated by the guide frame. You may make it advance toward the mechanism 13. Further, the gap L between the partition plates 15 may be formed as an opening facing the guide frame.

Further, two stem removal mechanisms 13 are normally provided at a rear end side of the planting machine 11 at a predetermined interval, and in this case, the rear side floor surface 12a reaching the stem removal mechanism 13 is provided. A floor vibration device 17 may be provided for each.

As the power of the floor vibrating device 17 and the stem removing mechanism 13, a 12 V battery and a 12 V motor attached to the traveling vehicle 10 are used.

Since the automatic planting machine for sugar cane according to this embodiment is configured as described above, first, the sugar cane planting plant for planting sugar cane in the stem storage room 12 of the planting machine 11 connected to the traveling vehicle 10 is used. Store stem X. Then, when the operator starts operation and issues a command for planting work, the stem removal mechanism 13 on the rear end side of the planting machine 11 starts operating.

The floor vibrating device 17 provided on the back side of the floor surface 12 a of the stem storage room 12 operates. For this reason, the planting stem X is subjected to the vibration and is advanced toward the lower part of the stem removing mechanism 13 on the inclined floor surface 12a which is gradually inclined. At this time, the planting stems X are regulated by the partition plates 18 separated by a predetermined gap L slightly larger than the diameter of the stems X. Therefore, the planting stems X are directed one by one toward the stem removal mechanism 13. Are aligned and advanced.

The planting stems X taken in by the stem take-out mechanism 13 are raised by the stem take-out mechanism 13, and rotate down from the uppermost position while descending, one by one, above the pipe body 19. It is thrown into the opening, falls in the pipe body 19, falls from the opening on the lower surface of the pipe body 19, is covered with soil by the cutting tool 20, and is planted in the field.

[0025] As described above, the stems for planting are arranged and conveyed one by one from the stem storage room of the planting machine connected to the tractor, and the stem removing mechanism rotates the stems for planting one by one. The stems for planting are taken out from the stalk take-out mechanism and released one by one into a vertical pipe body, and dropped into the field while falling down in the pipe body for planting.

[0026] Therefore, compared to the conventional sugarcane planting operation in which the stem for planting is manually dropped from the traveling vehicle to the field one by one, all the operations can be performed manually by one operator, and automatically. Since the planting stalks can be dropped into the field, the workability at the time of planting can be improved and the cost can be reduced. The planting work time may be about 40 minutes per 10a, but the workability is remarkably improved as compared with the related art since no labor of an assistant is required.

In addition, since no assistant is required besides the operator, the danger at the time of planting operation can be eliminated. For this reason, it is possible to efficiently and safely plant sugarcane stalks and reduce labor and cost of work.

The illustrated shape and structure of the traveling planting machine 11 and the shapes and structures of the stalk take-out mechanism 13 and the floor vibrating device 17 are merely examples, and fulfill the functions described above. The design can be appropriately changed as long as it is a product.
