Japanese Utility Model Publication No. 62-13117

  In the case of the potato planter mentioned above, in the case of multi-row planting, the spacing between the planting lines is determined by the interval between the dropping conduits arranged in the direction crossing the traveling direction, and the planting strains in one line are determined by the working speed and the feeding timing of the feeding mechanism. It will be. However, in this planter in which seed potatoes are planted in a straight line, competition between the strains occurred at an early stage, and there was a problem that the yield of the harvested crop was likely to be reduced because the crops were not evenly arranged, and the yield was likely to reach a peak.

  In general, staggered planting is known as intensive planting. When staggered planting, competition between crops is reduced, yield as a harvested product is improved, and yields are easily increased. However, the conventional potato planter that supplies seed potatoes fed from the feeding mechanism to the fall conduit and drops it onto the field is a simple mechanism, so it is not possible to adjust the fall timing with the right and left fall conduits. There was a problem that staggered plants could not be planted between different stocks.

  This invention makes it an example of a subject to cope with such a problem. It is an object of the present invention to enable staggered planting by adding a simple device in a planting device for dropping seed crops on a field scene, enabling staggered seeding between appropriate strains without using power, etc. .

  In order to achieve such an object, a seed crop planting apparatus according to the present invention has the following configuration among several inventions described in the specification.

A seed crop planting device for spotting seed crops in a field scene while proceeding in one direction, comprising a drop conduit section for dropping seed crops fed out in grain units to the field scene with an interval, wherein the drop conduit section is , A single inlet, two drop outlets divided from the inlet to the left and right in the direction of travel, and a guide plate for guiding the seed crops thrown into the inlet toward one of the two drop openings The guide plate rotates by its own weight of the seed crop that has been thrown in, and switches the guide direction alternately for each grain of the seed crop , and the drop conduit section has two feed channels provided downward from the feed port. A seed crop planting apparatus comprising left and right drop channels divided into two, and sliding the drop channel toward the left and right to make the interval between the drop ports adjustable .

  The seed crop planting apparatus having such a feature can cause seed crops thrown into the dropping conduit section to fall alternately onto the field scene from the right and left dropping openings. This allows seed crops to be staggered between the appropriate strains in the field.

  Since the fall conduit portion is a structure that rotates by the weight of the seed crops to be introduced, it enables intensive staggered planting by adding relatively inexpensive parts. Moreover, since this dropping conduit part does not require special power and has a simple structure, it can be easily added to an existing potato planter. Therefore, intensive staggered planting can be easily performed by adding a seed crop planting device to an existing potato planter.

  According to the seed crop planting apparatus of the present invention that enables such staggered planting, planting between appropriate strains improves the light receiving system of the above-ground part, expands the rhizosphere region, and improves the yield of the harvest And increase sales.
