Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application This invention relates to a planting device for a transplanter, and can be used for transplanting vegetable seedlings, etc.

Prior Art As a prior art, as described in Japanese Unexamined Patent Application Publication No. 59-203410, the bottom plate of the seedling box frame in which the seedling box is housed so as to be movable in the vertical direction is connected to the lower part of the soiled seedlings in the seedling box. The side tank of the seedling extrusion rod is formed so as to close the area other than the row, and the seedling box frame is moved horizontally and the seedling box is moved vertically, and the seedlings in the seedling box are pushed into the soil by the seedling extrusion rod. The plants fall one by one into a planting device below while in a substantially upright position with the plant in the lower position, and the planting device is reciprocated up and down to plant the plants.

Problems to be Solved by the Invention Traditionally, in the transplantation of vegetable seedlings, etc., the seedlings are generally planted by dropping them into a lower planting device in an almost upright position using a seedling extrusion rod. In this type, a cylindrical planting device whose lower end can be opened and closed is reciprocated up and down between the upper seedling supply device and the lower planting soil surface. Seedlings are planted on the soil surface, and if the diameter of the cylindrical part of the planting device for inheriting the seedlings that are dropped from the seedling supply device by the extrusion rod is large, it is easy to align the dropping positions. However, if the degree of freedom of the seedlings is too large, the upright posture of the seedlings will become unstable and the planting performance will deteriorate, and if the degree of freedom is reduced for this reason, the alignment of the falling position will be poor and the seedlings will be stuck. There is a concern that this may damage the leaves of the seedlings, resulting in poor rooting. When planting the seedlings on the soil surface by opening and closing the thin cylindrical tip, it is difficult to correct the standing posture using this method, so the posture of the seedlings may tilt or fall over, making it difficult to stably place the seedlings. .

Therefore, the present invention solves the above-mentioned problems and enables seedlings to maintain a normal planting and standing posture without damaging them.

Means for Solving the Problems This invention provides a rotating case (2) that reciprocates up and down between one seedling feeding device (1) and the soil surface below. The seedling feeding device (
A seedling holder is constructed in such a way that it rotates in the opposite direction to the rotating direction of the rotating case (2) in order to lower the seedlings in a parallel manner to the planting position on the soil surface while maintaining the seedling holding posture from 1). (3)
The structure of an implantation device of a transplanter is provided with:

Functions and Effects of the Invention The seedlings arranged in the seedling feeding device (1) are placed at the tip of the rotating case (2) which rotates back and forth at the upper limit position of the rotating case (2). The seedling holder (3) is held in place by the provided W holder A (3), and the seedling holder (3) is moved to the rotating case (2) so that the seedling holder (3) is lowered in parallel to the planting position on the soil surface.
The seedlings held by the seedling holder (3) are planted on the soil surface at the lower limit position of the rotation case (2) while rotating in a direction opposite to the rotation direction of the rotation case (2) in conjunction with the downward rotation of the seedling holder (3). This will remain in place.

In this way, the seedlings are transferred from the seedling supply device (1) to the seedling holder (3).
), the seedlings are held securely in a parallel position that is almost the same as the position in which they are planted and placed on the soil surface, and the seedlings are held and lowered until they are about to be planted and placed in the soil. The seedlings can be planted in a stable and normal posture at all times without tilting or overturning the standing posture or damaging the leaves etc. when planting the seedlings.

A connecting rod (38) connects the tip of the arm and a position where the rotation case (2) can be efficiently rotated about the rotation fulcrum by the rotation of the rotation arm (37). In addition, just before the rotating case (2) rotates downward and plants the seedlings on the soil surface, groove-making claws (4B) are installed on the rotating case (2) so that a groove can be formed in which the seedlings are planted and placed. trade.

Further, the lead shaft (38) of the left-right moving mechanism that is located further rear of the seedling planting drive shaft (17) of the interlocking case (15) and reciprocating the seedling feeding device (1) in the left-right direction is connected to the interlocking case (15). 15) and a cylindrical support frame (40) extending rearward from a position near the inner side of the swing case (lO) of the right cylindrical case (9) to an arbitrary length, and this lead shaft (38) At the top of the front end pulley (41) and rear end pulley (42)
A seedling supply bell (43) is installed,
The interlocking case (43) is arranged so that the front end pulley (41) of the supply belt (43) can pass through without interference when the supply belt (43) crosses the interlocking case (15) as it moves in the left-right direction. 15) is provided with four parts, while the supply bell) (

35) After (3B) plunges into the seedling that has come to that position, it closes and clamps it by the action of cam (2B) (28), and rotates to maintain the clamping posture to the lower limit of rotation position. As the case (2) rotates downward, the seedling holder (3) is rotated in the opposite direction to the rotation direction of the rotating case (2) by the sprocket (21) (22) and their connecting chain. The seedlings held by the seedling holder (3) are lowered, and at the lower limit position of the rotation, the cams (2El) (2B) release the left and right seedling trays (35) (3B) to release the seedlings held by the seedling holder (3). Since the seedlings are planted on the soil surface, the seedlings can always be planted in a stable and normal posture. In addition, since the left and right seedling trays (35) (3B) hold the seedlings from the front side, there is no possibility that the seedlings will be caught on the rear part of the seedling tray and damaged.

In addition, the power transmission of the cams (2El) (2B) for opening and closing the left and right seedling trays (35) (3B) is made into a chain configuration, which makes positioning of the cams (2B) (2B) easy. In this case, the distance between the gear axes is fixed to some extent, so there are major restrictions.
