Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a transfer conveyor that carries and transports seedling raising pots that are partitioned left and right and front and back and have a rectangular shape in plan view and have a collection of independent seedling raising pots. This invention relates to a seedling device that sows seeds into a seedling pot using a seeding device installed above the seedling pot, and more specifically, to a seedling device floating prevention device that prevents the seedling device from floating upward while being sown by the seeding device. .

(Prior art) Conventionally, when a large number of seedling pots are arranged in a row of seedling pots arranged left and right and front to back, when the seedling pot is placed on a belt conveyor and transported, a sowing machine on the conveyor is used to sow seeds into each seedling pot. I was getting used to it. This seeding machine sowed seeds into the seedling pots in a straight line horizontally on the left and right.

For this reason, if a floating prevention body is installed to hold down the top surface of the seedling nursery to prevent it from floating during sowing, the prevention body must be placed in a place other than this sowing position. The preventers were provided at the front and rear.

(Problems to be Solved by the Invention) The conventional technology has a structure in which seeds are sown continuously on the left and right horizontal lines without shifting back and forth in the sowing position for each seedling pot of the seedling nursery. When pressing down on the top surface of the seedling nursery, anti-floating bodies were provided only at the front and rear of the seedling except for the sowing position. For this reason, since the seeding position part cannot be held down at all, the seedling nursery device floats up at this part, making it impossible to carry the seedlings accurately and making it impossible to perform even seeding work.

(Technical Means for Solving the Problems) The present invention has solved the problems of the prior art described above by the following technical means.
