Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a rice transplanter for sequentially dividing and planting pine seedlings for planting stocks from pine seedlings, and to a seedling loading device for loading pine seedlings for planting.

Conventionally, in a rice transplanter that divides and plants pine seedlings placed on a seedling tray using a seedling dividing and planting movement body, the seedling tray on which the pine seedlings are loaded is placed on the seedling sending end side. Since it is installed at an angle,
A seedling pusher is provided to prevent pine seedlings from buckling or turning over on the seedling stand.
Furthermore, a seedling stopper is provided to prevent pine seedlings from moving toward the seedling delivery end when the supply of seedlings is temporarily interrupted.

However, when hanging the seedling stopper mentioned above,
First, the seedling pusher must be raised, the pine seedlings must be lifted up, and the seedling stopper must be lowered.This operation is not only complicated, but also requires the operator to go around to the front of the seedling stand each time to perform the operation. The reality is that this causes inconvenience to the work. In addition, if the seedling presser does not reliably hold down the pine seedlings on the seedling platform, there is a problem that the posture of the divided seedlings will be disordered, making it impossible to perform the planting work in an orderly manner.

The purpose of the present invention is to solve the above-mentioned problems, and in particular, the seedling stand is provided so as to be inclined toward the seedling sending-out end side, and the seedling stand is provided with a seedling stand inclined toward the seedling sending-out end side of the pine seedlings. A seedling stopper that prevents the migration of pine seedlings, and a seedling pusher that prevents buckling and reversal of pine seedlings are each provided so as to be movable up and down toward the upper side of the sloping direction of the seedling stand. By connecting the body and the pine seedlings through an interlocking mechanism that rotates them in opposite directions, the seedling press body and the pine seedlings on the seedling platform can be securely pressed and the planting work can be carried out in an orderly manner. It is an object of the present invention to provide a seedling mounting device for a rice transplanter, which allows the engagement and disengagement of a stopper to be easily performed in conjunction with the operation of a seedling pusher.

To explain the structure of the present invention with reference to an embodiment shown in the drawings, 1 is a frame of a rice transplanter, 2 is a float, and 3 is an operation handle, and the operation handle 3 is tilted backward at the rear of the frame 1. It is installed in the shape. Reference numeral 4 denotes a seedling platform on which pine seedlings are mounted, and this seedling platform 4 is constructed above the operation handle 3 in a manner that is tilted toward the seedling delivery end along the steering wheel, with a low front and rear height, and This seedling platform 4 is adapted to be driven back and forth from side to side. A seedling receiver 5 fixed to the machine body is provided opposite to the seedling sending end of the seedling platform 4, and a seedling outlet 6 is formed in the seedling receiver 5. Reference numeral 7 denotes a seedling dividing and planting moving body, and this seedling dividing and planting moving body 7 is disposed in front of the seedling delivery end of the seedling platform 4 and opposite to the seedling outlet 6 of the seedling receiver 5.

Support frames 8 are respectively attached to the seedling delivery end edges of both side walls 4a, 4a and intermediate partition wall 4b of the seedling platform 4, and a seedling stopper is attached to a rotating shaft 9 pivotally supported by the support frame 8. 10 is fixed, and a seedling pusher 12 is fixed to a rotating shaft 11 which is pivotally supported on the support frame 8, and these seedling stopper 10 and seedling pusher 12 are respectively placed on the upper side of the seedling platform 4 in the inclined direction. It can be moved up and down freely. The seedling stopper 10 and the seedling pusher 12 are moved via an interlocking mechanism 13. When the seedling pusher 12 is lowered, the seedling stopper 10 is raised, and when the seedling pusher 12 is raised, the seedling stopper 10 is moved. The interlocking mechanism 13 rotates the seedling stopper 10 and the seedling pusher 12 in opposite directions so as to lower them. This interlocking mechanism 13 connects an arm 14 fixed to the rotation shaft 9 on the side of the seedling stopper 10 and an arm 15 loosely fitted to the rotation shaft 11 on the side of the seedling pusher 12 through a long hole 15a. They are loosely connected to each other through the long end holes 15b, and the locking portion 15c on the proximal end side of the arm 15 and the cutout portion 8a on the support frame 8 side allow the seedling holding body 12 to be placed in the seedling holding position. Locking stopper 1
6 are configured. The arms 14 and 15 constituting the interlocking mechanism 13 are housed within the support frame 8, and both side walls 4a, 4a of the seedling stand 4 are
Alternatively, it is provided within the thickness and width of the intermediate partition wall 4b. Reference numeral 17 denotes a seedling delivery roll, which is provided on the bottom surface of the seedling delivery end side of the seedling platform 4.

In the present invention configured as described above, pine seedlings to be used for seedling planting are placed on the seedling stand 4, and the seedling dividing and planting movement body 7 divides the pine seedlings into individual plants for planting. When placing the pine seedlings on the seedling stand 4, first pull the seedling pusher 12 toward you to remove the stopper 16, and then rotate it upward to place the pine seedlings. do. When the seedling pusher 12 is lowered, the seedling stopper 10 is raised in conjunction with this, so that the seedling pusher 12 prevents the floor surface of the pine seedlings on the seedling platform 4 from floating upward, and the pine seedlings are held down by the seedling pusher 12. The seedlings are successively pulled out to the seedling delivery end side by the seedling delivery roll 17 without buckling or turning over. Since the seedling pushing body 12 is pivotally supported on the support frame 8 attached to the seedling sending edge, this seedling pushing body 12
This makes it possible to securely hold the pine seedlings on the seedling platform 4 from the dividing position at the seedling sending end to the upper side in the slope direction, and transfer the seedlings from the seedling outlet 6 of the seedling receiver 5 to the seedling dividing and planting movement body 7. Therefore, the seedlings are always planted in a proper posture and divided into individual plants. On the other hand, if you want to temporarily interrupt sending out the seedlings during seedling planting, you can move the pine seedlings slightly above the position of the seedling delivery roll 17 and raise the seedling pusher 12. Since the seedling stopper 10 is lowered in conjunction, the pine seedlings are prevented from moving toward the seedling delivery end side by the seedling stopper 10. In this way, the seedling stopper 10 can be engaged and disengaged by simply operating the seedling pusher 12 up and down, and since the seedling pusher 12 can be operated from the operating position, the engagement and detachment of the seedling stopper 10 can be performed extremely easily. be able to. In addition, since the seedling holding body 12 is stopped by the stopper 16 at the seedling holding position,
The seedling presser is securely held. Also, seedling stopper 1
0 and the seedling pusher 12 are housed in the side walls 4a, 4a of the seedling platform 4 or the intermediate partition wall 4b, so by providing the interlocking mechanism 13,
Doesn't require extra space.

In short, the present invention provides a rice transplanter that divides pine seedlings on a seedling platform and plants them sequentially from the seedling sending end to the planting stocks, in which the seedling placing table is tilted toward the seedling sending end. The seedling stand is equipped with a seedling stopper that prevents the pine seedlings from moving toward the seedling sending end, and a seedling pusher that prevents the pine seedlings from buckling or turning over, each facing upward in the direction of the inclination of the seedling stand. The seedling stopper and the seedling pusher are connected via an interlocking mechanism that rotates them in opposite directions. The seedling pushing body can be installed at the edge of the seedling sending end of the seedling tray, so the seedling pushing body, which rotates up and down, moves the pine seedlings on the seedling tray from the seedling dividing position at the seedling feeding end in the inclined direction. It is possible to securely hold down the seedlings by placing them on the upper side, and the seedlings placed on the planting stock can be divided and planted in an orderly manner, always with the appropriate seedling posture. In addition, by simply moving the seedling pusher up and down from the operation position, which faces the upper side of the seedling platform in the direction of inclination, the seedling stopper connected via the connection mechanism can be rotated in the opposite direction. The engaging and disengaging operation of the stopper can be easily performed in conjunction with the operation of the seedling pusher, and this has an extremely useful novel effect of simplifying the work and significantly improving efficiency. .
