  • Patent number: 4597343
    Abstract: A transplanting machine having rotary transplanting rods which clasp the forwardmost one of a row of continuous potted seedlings of a continuous paper tube pot assembly of potted seedlings so as to draw out the row of continuous potted seedlings. Further, the rotary transplanting rods separate the forwardmost one from the row of continuous potted seedlings in cooperation with a stopping mechanism for stopping such drawing out, and plant the separated potted seedling in the field while clasping it.

  • Patent number: 4167911
    Abstract: The present invention relates to a method wherein seedlings, raised in a paper tube assembly connected together by means of connecting portions having a separating line forming the separation course in each, are continuously pulled out while separating the tubes one by one and planting them in the field. In the separation of seedling tubes, a transplanter is provided with rollers for pulling out continuous seedling tubes and other rollers for separating the pulled out seedling tubes into individual seedling tubes. The latter has a faster rotating speed than that of the former and has a cone-like shape or is mounted so as to incline with respect to the former, thereby separating paper tubes into individual pot bodies at the connecting portions, one by one, while moving the separation acting points progressively. The separating-line in each connecting portion has an unjoined separation-guiding-portion extending from one end to 20-70% of the height of the connecting portion.

  • Patent number: 4132337
    Abstract: The present invention relates to a method wherein seedlings, raised in a paper cylinder assembly connected together by means of connecting portions having a separating line forming the separation course in each are continuously pulled out while separating the cylinder one by one and planting them in the field. In the separation of seedling cylinders, a transplanter is provided with rolls for pulling out continuous seedling cylinders and other rolls for separating the pulled out seedling cylinders into individual seedling cylinders. The latter has a faster rotating speed than that of the former and has a cone-like shape or is mounted so as to incline with respect to the former, thereby separating paper cylinders into individual pot bodies at the connecting portions, one by one, while moving the separation acting points progressively. The separating-line in each connecting portion has an unjoined separation-guiding-portion extending from one end to 20-70% of the height of the connecting portion.
