  BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sugarcane continuous planting machine, an adjusting device for easily adjusting the amount of seed cane planted, and a sugarcane continuous planting machine provided with the planting amount adjusting device.

  BACKGROUND ART Conventionally, for planting sugarcane seeds, a sugarcane planting machine that transports seed millet in a hopper indexed by a tractor by a conveyor, drops the seed millet in a field ditch, and continuously plants the seed cane has been used (Patent Documents 1 and 2). ).

  In these conventional sugarcane continuous planters, a conveyor for transferring seed millet is formed along the floor and side walls of the hopper, and at least the upper side of the side walls is erected vertically or steeply. As they approached the millet outlet, they stood up vertically or steeply.

  When the conveyor that transports seed mills rises vertically or steeply in this way, if many trashes are mixed in the seed millet, the seed millet may spill out from the gutter-shaped cup section provided on the conveyor. In some cases, an appropriate amount of seed millet could not be transported.

  Therefore, the present applicant sets the rising angle of the conveyor in the hopper not to be vertical or steeply inclined, but to be gently inclined, so that even if many trashes are mixed in the seed millet, the seed millet spills out from the cup portion. We developed a continuous sugarcane planter that can be transported without any problems.

  However, such a sugarcane planter can transport seed millet even if trash is mixed, but since seed seeds are dropped from the cup part, the seed mill may be transported more than necessary. This made it difficult to adjust the amount of seed planting.

  As described above, in the sugarcane planting amount apparatus 1 of the present invention, the wide area 102 or the narrow area 101 is formed according to the size of the angle formed between the seeding member 12 and the seeding member 13 in a side view. . The number of the narrow regions 101 and the wide regions 102 can be arbitrarily determined. However, it is preferable that the number of the narrow regions 101 is two or more and the number of the wide regions 102 is one. It is more preferable that the region 102 be one place.

  FIG. 5A is an enlarged cross-sectional view of a mounting portion of the seed sweeping member 12 and the seed sweeping member 13 with respect to the shaft portion 11. As shown in the drawing, the seeding member 12 includes a core rod 121 and a tubular covering member 123 attached so as to cover the outer peripheral surface thereof. The core rod 121 is a rod-like body having a screw portion 122 on at least an outer peripheral surface of an intermediate portion thereof. The core rod 121 is attached to the shaft portion 11 by inserting the core rod 121 into the hole portion 111 and on both sides of the shaft portion 11. After penetrating the shaft portion 11 so that both ends of the core rod 121 project by the same length, two nuts 124 are screwed into the screw portion 122 and tightened from both side surfaces of the shaft portion 11. The method of attaching the core rod 121 to the shaft portion 11 is not limited to this, and other known fixing means such as welding can be adopted. According to this, the attachment and detachment of the seed dispensing member 12 is easy, which is preferable.

  The covering material 123 is preferably formed of an elastic tube material such as rubber or vinyl, so that the surface of the seed milled off by the seed sweeping member 12 is not damaged. Further, as in the present embodiment, if the covering material 123 is formed to be longer than the leading end of the core rod 121 so that the leading end of the covering material 123 is left, the leading end side of the seeding member 12 has flexibility. However, it is possible to avoid troubles such as a seed mill being caught between the cup part 31 of the conveyor 3 and the seed wiping member 12.

  As shown in FIG. 5B, the seed removing member 13 also includes a core rod 131 and a covering material 133, and a nut 134 is screwed into a screw part 132 of the core rod 131 to be fixed to the shaft part 11. However, in the seeding member 12, the core rod 121 projects by the same length on both sides of the shaft portion 11, whereas in the case of the seeding member 13, the seeding member 13 is formed from one of the holes 111. The difference is that the core rod 131 protrudes with a sufficient length, and the core rod 131 protrudes from the hole 111 on the opposite side only by a length necessary for screwing the nut 134.

  The screw part 122 of the seeding member 12 is formed in the middle of the core rod 121, and the screw part 132 of the seeding member 13 is formed at one end of the core rod 131. 132 is not limited to these parts, and may be formed over the entire length of the core rods 121 and 131.

  As shown in FIG. 1, the sugarcane planting amount adjusting device 1 of the present invention is configured such that the shaft portion 11 is disposed substantially horizontally above the conveyor 3 within the opening portion 41 of the duct portion 4. It is pivoted on. More specifically, the shaft portion 11 extends in a direction parallel to a pulley (not shown) of the conveyor 3, and when the seeding members 12, 13 face the upper surface direction of the conveyor 3, the seeding member 12, 13 and a top surface of the conveyor 3 at a predetermined interval.

  Further, a pulley 14 is mounted on one end of the shaft 11 that is exposed to the outside of the duct 4. The pulley 14 is provided so as to be driven by a pulley (not shown) of the conveyor 3 by a chain 15. That is, in the present embodiment, the rotating force of the pulley of the conveyor 3 serves as a driving unit of the sugarcane planting amount adjusting device 1. By the driving means, the shaft 11 of the sugarcane planting amount adjusting device 1 also rotates in the same direction in conjunction with the rotation of the conveyor 3.

  Next, a series of operations of the sugarcane planting amount device 1 of the present invention will be described with reference to FIGS. In this figure, it is assumed that the shaft 11 of the sugarcane planting device 1 rotates counterclockwise. In the drawing, the seed millet S indicated by a circle (丸) is scooped from below by the cup portion 31 of the conveyor 3, and climbs on the conveyor 3 from the lower right to the upper left. In addition, in order to make it easy to understand, in this figure, a total of five seed millet S are properly aligned in front of the cup portion 31, but actually a trash is sandwiched between the seed millet S or the direction of the seed millet. Are not arranged in this order because they are also scattered. 6 (a) to 6 (d), in order to facilitate understanding, the seeding member 12 is divided into a seeding member 12a protruding to one side and a seeding member 12b projecting to the opposite side. explain.

  FIG. 6A shows a state immediately before the seed millet S that has climbed the slope is swept down into the hopper 2 by the seed sweeping member 12a. In the next FIG. 6 (b), the top seed millet S climbing up to the upper part of the conveyor 3 is about to be swept into the hopper 2 by the seed sweeping member 12a. In FIG. 6 (c), the shaft portion 11 is further rotated by half a half from the state of FIG. 6 (b), and the third seed millet S from the top is swept down into the hopper 2 by the seed sweeping member 12b. Is about to be. Although not shown, the second seed millet S from the top has already been removed into the hopper 2 by the seed removal member 13.

  FIG. 6D shows a state in which the shaft portion 11 is further rotated from FIG. 6C. At this time, after the seeding member 12b has scraped the seed millet S, the next seeding member 12a is rotated. A relatively long interval occurs before moving to the position where the millet S is to be removed. That is, in the narrow region 101 between the seed sweeping member 12a and the seed sweeping member 13 and between the seed sweeping member 13 and the seed sweeping member 12b, an interval of 1/4 rotation occurs, while the seed sweeping member 12b and the seed sweeping member 12b In the wide area 102 with the wiping member 12a, an interval corresponding to 周 rotation occurs. Then, in the longer interval, the fourth and fifth seed millet S from the top are dropped into the duct portion 4 without being swept off by the seed sweeping member 12a.

  In this way, excess seed millet S is appropriately paid back into the hopper 2 by the seed wiping members 12a, 12b, and 13, and one or two seed millet S remaining on the conveyor 3 are planted on the field. Become.

  The sugarcane planting amount adjusting device 1 of the present invention can appropriately adjust the sugarcane planting amount by increasing or decreasing the number of seeding members 12 and 13. For example, if the seed dispensing members 12 and 13 are further thinned from those of the present embodiment, the number of seeds milled into the hopper decreases, and as a result, the planting amount can be increased. Conversely, if seeding members 12 and 13 are additionally provided in the holes 111 where the seeding members 12 and 13 are not attached, the number of seed millers that are removed in the hopper increases, and as a result, the planting amount Can be reduced.

  The shape of the seed-wiping members 12 and 13 is not limited to a rod shape, and may be a plate shape or another shape protruding from the shaft portion 11 as long as the seed milling members can be appropriately wiped off. In addition, the driving means of the sugarcane planting amount adjusting device 1 is not limited to the driving force of the pulley of the conveyor 3 as in the present embodiment, as long as it rotates the shaft portion 11 in the same direction as the pulley of the conveyor 3. , Other driving forces may be used.
