Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a seedling feeding device for a transplanter that facilitates the supply of seedlings.

[Prior art]

As a conventional technique of this type, there is a seedling pusher attached to a seedling tank that forcefully feeds the seedlings stored in the seedling tank toward a seedling outlet.

[Problem that the invention seeks to solve]

However, since the above-mentioned seedling pusher is attached to the seedling tank, it gets in the way when replenishing seedlings, resulting in extremely poor work efficiency.

[Means to solve the problem]

In order to solve the above-mentioned problems, the present invention provides a seedling feeding device 3 of a transplanter that feeds out seedlings stored in a seedling tank 1 to a seedling take-out port 2.
This is a seedling feeding device for a transplanter, characterized in that it is configured to be able to be switched to a non-operating state further away.

〔Effect of the invention〕

Since the seedling feeding device 3 is configured to be switchable between a seedling feeding state and a non-working state away from the seedling tank 1, the seedling feeding device 3 can be set in the seedling feeding mode during seedling transplanting to ensure that the seedlings are not fed properly. A feeding action can be performed, and when replenishing seedlings, the seedling feeding device 3 can be quickly switched to a non-operating state away from the seedling tank 1, and seedling replenishment can be easily performed.

The other end of the rotating body 31 is attached to the claw support body 25 with an adjustment bag @32.
are in contact through. The adjustment device 32 is connected to the pawl support 25
A screw 33 is provided in a screw hole provided in the hole so that it can be adjusted freely in the direction of the e-port, and is fixed with a nut 34 after the adjustment. The scraping feed device @19 configured as above is
The rotation of the rotary tube 20 causes the entire body to reciprocate by a certain amount in the harrow direction, and when the rake-feed claws 22 engage the seedlings in the seedling tank 1 due to the rotation in the convex direction, the actuator is moved by the cam body 29. 28 is pushed up, and the hollow shaft 26 is also pushed up via the bullet 27. Then, the rotating body 31 rotates in the E direction and the claw support 25 rotates in the H direction, so that the scraping claws 22 and 22
The tip of the holder operates upward to feed out the seedlings in the seedling tank 1 to the seedling outlet 2.

Reference numeral 3 denotes a seedling feeding device, in which a rotating arm 3 is attached to a shaft 36 supported by support rods 35 extending from the seedling tank 1.
7 boss 38 is attached rotatably.

A seedling presser 41 is attached to this rotary arm 37 via a parallel link 40 consisting of two upper and lower support rods 39. A six-shot machine 42 is a mounting piece fixed to the lower support rod 39 of the parallel link 40. The pivot pin 45 between the lower support rod 39 and the seedling presser 41 is provided between the lower support rod 39 and the attachment piece 44 fixed to the seedling presser 41 in the state shown by the solid line and the state shown by the two-dot chain line in FIG. It is located beyond the position of Reference numeral 46 denotes a locking body rotatably pivoted to a pin 48 provided on an arm 47 fixed to the shaft 36, and the locking portion 46 is fixed to the lower support rod 39 of the parallel link 40. By locking the pin 50, the seedling feeding device @3 is held in the state shown by the solid line in FIG. 3. Note that the bullet 51 is provided to pull the locking body 46 until it comes into contact with a stopper 52 fixed to the arm 47. In addition, the seedling feeding device @3 is urged to rotate in the direction of the arrow 53 by the bullet 53, and the rear side of the seedlings on the seedling tank is pressed against the seedling pressing body 41 in the state shown by the two-dot chain line in FIG. A seedling pressing plate 54 provided at the tip of the seedling pressing plate 54 is provided to press the seedling.

The seedling tank 1 is formed by removably forming the upper half of the seedling mounting portion 16 for each row to form a cassette-shaped tank 1 as shown in FIG.
a, and a locking rod 1b is provided at the top of the cassette-shaped tank 1a to prevent rush seedlings from being pulled out and falling;
A gripping portion 1c is provided at the bottom thereof.

Before putting the riding-type rush planting machine 4 configured as described above into a paddy field, a rush lock having a comb-shaped locking rod 55a...grip portion 55b is attached to the front part of the cassette-shaped tank 1a. Six cassette-shaped tanks 1a each having a member 55 attached thereto, loaded with grass seedlings, and further attached with a locking rod 1b.
1 and 11, and then six cassette-shaped tanks 1a loaded with other rush seedlings are attached to the upper half of the seedling mounting part 16 for each row, and the locking rod 1c and the rush locking member 55 are attached. The tip of the locking rod 55a of the rush locking member 55 is bent outward as shown in FIG. is never disturbed. ), push down the rush seedlings so that the front part of the rush seedlings reaches seedling outlet 2.

The seedling feeding device 3 is set so that the seedling pressing plate 54 of the seedling feeding device 3 is in contact with the rear side of the rush seedling. Then, when the prepared riding type rush planting machine 4 is put into the paddy field and each part is driven by the engine, the rush planting machine 7 is pulled by the riding type traveling device 5, and the seedlings are transferred by the seedling feeding device 3. While being pressed, the seedlings are sequentially fed out toward the seedling outlet 2 by the scraping device 19.

The seedling tank 1 in which the seedling planting tool 17 is reciprocated from side to side
The seedlings are divided into individual plants and planted on the leveled soil surface using the leveling float 18. When there are few remaining seedlings placed on the seedling tank 1, the seedling feeding device 3
When the seedling feeding device 3 is held by the grip portion 41a provided on the seedling pressing body 41 and pushed toward the rear of the machine body, the seedling feeding device 3 is locked by the locking body 46 and held in a non-operating state. Then, remove the empty cassette-shaped tank 1a, and remove the left and right spare seedling mounting stands 11.
A cassette-shaped tank 1a loaded with rush seedlings placed on 11 is attached to the upper half of the seedling tank 1.

Then, remove the locking rod 1c and rush locking member 55, push down the grass seedling, hold the grip part 41a of the seedling feeding device @3, and pull it toward the seedling tank 1 side.
The seedling feeding device 3 is set so that the seedling pressing plate 54 touches the seedling. (In this case, when the grip part 41a of the seedling feeder @3 is pulled toward the seedling tank 1 side, the locking body 46 rotates in the upward direction against the bullet 51, so the pin 50 is locked. (The seedling feeding device 3 can be brought into operation by being disengaged from the locking portion 49 of the body 46.) When the seedling feeding is completed, the transplanting operation is subsequently performed.

In the above embodiment, an example in which the present invention is applied to a riding-type rush planting machine 4 is shown, but the present invention may also be applied to a walking-type rush planting machine, and further, It may also be used in a transplant machine.
