Description

TECHNICAL FIELD The present invention relates to a seedling take-out device for a transplanter, which can be used for block-shaped seedlings of vegetables and the like.

2. Description of the Related Art As a conventional technology, as described in Japanese Patent Laid-Open No. 59-203410, a bottom plate of a seedling box frame that houses a seedling box so as to be movable in a vertical direction is provided below the seedlings with soil. Part of the seedling extruding rod is formed so as to close except one lateral row, and the seedling box frame is moved laterally and the seedling box is moved vertically so that the seedlings in the seedling box are soiled by the seedling pushing rod. In a substantially upright posture in which the lower part of the plant is in a lower position, one plant is dropped into the lower planting device, and the planting device is reciprocated up and down for planting.

Problems to be Solved by the Invention Conventionally, in planting seedlings of vegetables, etc., one piece of rock-like seedlings raised in a seedling box or the like is extruded by a seedling planting device from a seedling box placed on a seedling feeding device. The seedlings are planted, but instead of this seedling box, the seedlings are raised by a deformed paper pot that is trapezoidal in side view and has its long-side peripheral edge floor integrally formed. When one block-shaped seedling that has been planted is sandwiched and separated by a seedling planting device for planting, when the block-shaped seedling is sandwiched and separated by the planting device of the seedling planting device, the trapezoidal length of the deformed paper pot Since the floor-side integrated floor is difficult to separate, improper pinching of the block-shaped seedlings by the planting tool may occur, or the block-shaped seedlings may be damaged if the clamping force of the planting tool is increased to prevent improper pinching. And it becomes a problem.

Therefore, in the present invention, it is intended to solve the above-mentioned problems regarding the pinching separation of the block-shaped seedlings and prevent the planting failure and the damage of the block-shaped seedlings due to the unstable pinching of the block-shaped seedlings by the smooth pinching separation. To do.
