Description

[Detailed Description of the Invention] Industrial Application Field This invention pushes out a unit number of potted seedlings at a time from a potted seedling box placed on a seedling stand at the top of the machine, and places the potted seedlings one by one on the ground surface. The present invention relates to a pot seedling feeding device for a seedling conveying belt of a transplanter configured to be planted in a container.

Conventional Technology This conventional seed transplanting machine is explained with the vertical side view in Fig. 4. 1 is a seedling stand, and the flexible pot seedling box shown in Fig. 3 is placed in a pot seedling box with pot seedlings a planted therein. It is formed so that it can be set. An extrusion rod 2 is provided at the rear of the seedling stand 1 so as to be movable back and forth. This extrusion rod 2 pushes out the potted seedling a from the potted seedling box on the seedling stand 1, and inserts and supports the potted seedling a into the front seedling holder 3. The pot seedling a, which is reversibly provided at the tip of an arm 4 rotatably provided on the body of the seedling holder 3 and is inserted and held in the seedling holder 3, is provided at a passing position of the seedling holder 3. The seedlings are scraped off onto the upper surface of the lower seedling conveying belt 11 by the flip-out blade 5.

However, the pot seedling box mentioned above, as shown in Figure 3,
A large number of pot seedling rooms p, p... are arranged in a checkerboard pattern, and the extrusion rod 2 in the transplanter is capable of extruding a horizontal row of pot seedlings a, a... from the seedling box at once. A large number of them are arranged in parallel in the shape of a comb blade. Therefore, the seedling holder 3 for receiving the potted seedlings a, a, .

Problems to be Solved by the Invention According to the above-mentioned conventional apparatus, even if so-called "adult seedlings" with large stems and leaves are dropped from the seedling tray 3 onto the upper surface of the seedling conveying belt 11, the belt 1
1. The tower can be mounted in a predetermined position without rolling on the top surface.
However, so-called "germinated seedlings" that have just germinated
Since the stems and leaves are small, they tend to roll and become irregular when placed on the top surface of the belt 11.

The present invention aims to eliminate the drawbacks of the above-mentioned prior art and to provide a device for feeding pot seedlings to a seedling conveying belt in a transplanter, which allows even "germinated seedlings" to be placed regularly on the upper surface of the seedling conveying belt.

Means for Solving the Problems In order to achieve the above object, the present invention provides a transplanter configured to take out pot seedlings and plant them from a pot seedling box placed on a seedling stand. A seedling holder that can freely receive the potted seedlings is supported at the tip of the movable arm, and a holding device for the potted seedlings consisting of a latching claw and a supporting claw is disposed at a passing position of the seedling holder, and the holding device This transplanter is configured so that when the device approaches directly above the seedling transport belt below, the support claws retreat, and when the support claws retreat, they continue to rise, and when the latching claws reach their upper limit, the support claws protrude and return to their original state. The gist of this paper is the structure of a pot seedling feeding device for a seedling conveying belt.

Effect Since this invention is configured as described above,
The potted seedlings supported by the seedling tray are transferred to the potted seedling holding device above the seedling conveying belt. The seedling holding device that has received the potted seedlings is rotated downward by a suitable means such as a cam mechanism, and the supporting claws quickly retreat directly above the seedling conveying belt, and the potted seedlings are released onto the upper surface of the belt. However, since the top surface of the pot seedling is lightly held down by the hook, it does not roll and is placed quietly on the top surface of the belt. When the potted seedling is placed on the upper surface of the belt, the holding device rotates upward, and when the latching claw reaches its upper limit, the supporting claw protrudes and returns to its original state, ready for the next operation.

Embodiment This invention will be explained with reference to FIGS. 1 to 3. Reference numeral 1 denotes a seedling stand, and a flexible pot seedling box (see FIG. ) is formed so that it can be inserted freely. A push-out hole is bored in this seedling platform 1, and a seedling push-out rod 2 is provided behind the push-out hole so as to be movable back and forth. This extrusion rod 2 pushes out the potted seedlings a from the potted seedling box placed on the seedling stand 1, and inserts and supports them into the seedling holder 3 waiting in front. When the arm 4 rotates 90 degrees, the seedling holder 3 moves approximately
It is provided at the tip of arm 4 so that it can be rotated 180 degrees. Therefore, the seedling receiver 3 receives the potted seedlings A facing forward.
is supplied backwards to the lower pot seedling holding device 5. Then, the arm 4 rotates upward and returns the empty seedling tray 3 to its old position in preparation for the next operation.

The pot seedling holding device 5 consists of a latching claw 7 provided in the shape of a comb blade on the edge of a rocking plate 6, and a support claw 8 supported in parallel to the latching claw 7, and a support claw link mechanism 9. It is supported to move back and forth while rotating up and down in conjunction with the swinging of the swing plate 6.
Therefore, in the clamping device 5, when the swing plate 6 is at the upper limit, the latching claws 7 and the support claws 8 are supported in parallel rearward facing the seedling receiver 3 rotating downward, and the seedling receiver 3 is in a state where it can freely receive the potted seedling a held by. When the clamping device 5 receives the potted seedling a, it begins to slowly descend via the rocking plate 6 under the guidance of the cam mechanism 10, and when the potted seedling a approaches directly above the seedling conveying belt 11, the link mechanism 9 is activated and the supporting claw 8 Because the pot quickly retreats, the pot seedling a is released onto the upper surface of the belt 11. However, since the pot seedling a is lightly held down by the latching claw 7, it is placed at a predetermined position without rolling on the upper surface of the belt 11. Next, when the rocking plate 6 rotates upward and the locking claw 7 reaches its upper limit, the supporting claw 8, which had retreated, is guided by the link mechanism 9 and protrudes, returning to its old state.

To explain the operation of the above embodiment, first, a pot seedling box with pot seedlings a planted therein is set on the seedling platform 1. Next, when the seedling extrusion rod 2 behind the seedling table 1 is operated, the extrusion rod 2 pushes out the potted seedlings a from the seedling box on the seedling table 1, and inserts and supports them into the seedling holder 3 waiting in front. Then, the arm 4 rotates downward, and the potted seedling a is supplied to the potted seedling holding device 5 located below. The clamping device 5 that has clamped the potted seedlings a descends quietly, releases the potted seedlings a directly above the belt 11, and places them orderly on the upper surface of the belt 11.

Effects of the Invention As described above, according to the present invention, in a transplanter configured to take out potted seedlings while planting them from a potted seedling box mounted on the machine body, even "germinated seedlings" with small stems and leaves can be placed on the upper surface of the seedling conveying belt. It has the effect of being able to be placed neatly without rolling.
