Description

[Detailed description of the invention] The present invention provides seedlings in a walking rice transplanter in which a seedling stand 6 is provided along the handle 3 which is tilted backwards, and a seedling box stand 9 for replenishment is provided on the machine body in front of the seedling stand 6. This relates to loading equipment. In such a rice transplanter, an operation lever 14 for a traveling clutch or a planting clutch is generally provided below the rear end of the seedling platform 6, so that when the pine seedlings 8a are supplied, the rear end of the supplied seedlings is If the seedling platform 6 protrudes and hangs down, the seedling platform 6 will move laterally while remaining in contact with the operating lever 14, etc., resulting in defects such as damage to the pine seedlings on the floor or seedlings falling apart. It was hot.

To solve this problem, as shown in FIG. 5 or 6, the upper end of the seedling stand 6 is bent upward in one or more steps, and the upper end of the seedling stand 6 is bent upward.
We have proposed a system in which the protruding part of the pine seedlings 8a is aligned with this, in order to prevent the pine seedlings from falling off due to overloading and to solve the above problem. Although sagging does not occur, the shape of the seedling stand 6 becomes complicated, resulting in defects that increase production costs.

In addition, in the conventional type, when taking out supplementary seedlings from the replenishing seedling box stand 9, there is no appropriate placement part between the replenishing seedling box stand 9 and the seedling loading stand 6, and the seedlings are stored inside the seedling box. There were problems such as it was difficult to take out the supplied seedlings, the work position was unstable, and it took a long time.

The present invention was devised to eliminate these deficiencies. In particular, the seedling platform 6 is provided with a reversing device 11 that is pivotally supported so as to be reversible in the front and rear directions, so that when the seedling stand 6 is placed in a forward position, replenishment is not possible. The seedling box 8 is pulled out to the front and supported by the replenishment seedling box stand 9 and the reversing device 11 so that the seedlings can be taken out easily. By supporting the protruding part with the reversing device 11, it is possible to prevent the protruding part from hanging down,
This completely eliminates all the deficiencies of the conventional system.

Hereinafter, one embodiment of the present invention will be described based on the drawings. In 1, an engine 2 is mounted, and a handle 3 is fixed to the rear part, the handlebar 3 is tilted so that the rear side is higher.
The body of the walking rice transplanter has a float 4 attached to the bottom and wheels 5 on both the left and right sides, and in front of the handle 3 is a seedling stand 6 tilted backwards in the same way as the handle 3. It is constructed so as to move back and forth, and a planting rod for scraping and planting the pine seedlings 8a in the seedling stand 6 is provided at the front part thereof.

Further, on the upper part of the machine body 1, there is a seedling box stand 9 for replenishing the pine seedlings 8a stored in the seedling box 8.
10 are installed in two levels, upper and lower. Reference numeral 11 is a reversing device installed between adjacent side walls 6a, 6a of the seedling stand 6. To explain this in detail, 12 is a reversing device that is folded into a horizontal holding portion 12a and left and right leg portions 12b, 12b to form a U-shape in plan view. The base of the frame 12 is rotatably supported on mounting seats 13, 13 provided halfway toward the upper ends of the adjacent side walls 6a, 6a, and the horizontal holding portion 12a is rotated forward and backward. It is designed to be able to rotate in the direction of. When the reversing device 11 is laid down backwards, the legs 12b are firmly supported by contacting the upper surface of the side wall 6a, and the horizontal holding portion 12b is positioned on the rear extension line of the seedling stand 6. On the other hand, when the reversing device 11 is laid down forward, the legs 12 engage the locking protrusions 1 provided on the mounting seat 13.
3a, so that the frame 12 is in a fixed position facing the replenishing seedling box stand 9 (in this embodiment, the frame 12 and the replenishing seedling box stand 9 are at approximately the same height). configured to be retained.

Reference numeral 14 denotes an operating lever for a traveling clutch, a planting clutch, etc., which is pivotally supported by a guide case 15 located below the rear end of the seedling stand 6 of the handle 3, and when moved upward, the clutch engages. , the clutch can be disengaged by moving it downward.

Note that 16 is a scraper for taking out the pine seedlings 8a from the seedling box 8.

The present invention is constructed as described above, and when the number of pine seedlings 8a in the seedling platform 6 becomes low during the planting operation and the seedlings are to be replenished, when the reversing device 11 is lowered forward, the frame body 12 is Supported by the locking protrusion 13a,
It is held in a horizontal position at approximately the same height as the supply seedling box stand 9. Therefore, the seedling box 8 on the supply seedling box stand 9 is pulled rearward, the lower surface of the rear end is placed on the horizontal holding part 12a of the frame 12, and the scraper 16 is placed between the pine seedling 8a and the seedling box 8. Insert pine seedling 8
All you have to do is scoop up the seedlings a onto the scraper 16 and transfer them to the seedling stand 6 to replenish the seedlings.The driver does not have to move forward to take out the seedlings, but can maintain stability by extending his hand from the operating position. You can take out and replenish seedlings in this position.

In addition, if the rear end of the pine seedlings 8a to be supplied protrudes from the seedling stand 6, the reversing device 11 may be folded backward and the protruding portion may be placed on the horizontal holding portion 12a and held. Often, the protruding rear end of the supplied pine seedlings 8a is securely held by the horizontal holding part 12a located on the rear extension line of the seedling platform 6 and does not sag. The seedlings will not be damaged by being hit, and the lever will not become difficult to operate due to hanging down.

In another embodiment shown in FIG. 4, a locking protrusion 12c is provided on the leg 12b of the frame 12, and when the reversing device 11 is laid down forward, the locking protrusion 12c
c is adapted to abut against the side wall 6a, and the reversing device 11 can be configured more easily.Also, instead of a rod-like member, it is formed with a plate-like horizontal holding member 12d, and the rear The planar surface catches the seedlings that protrude when the tree is laid down to more reliably prevent the seedlings from sagging.

As described above, the present invention is a walk-behind rice transplanter in which the seedling loading stand 6 is provided along the handle 3 in a backward-leaning position, and the seedling box stand 9 for replenishment is arranged on the body in front of it.
A frame 12 formed in a U-shape in plan view is mounted on the seedling stand 6.
A reversing device 11 is provided, whose bases at both ends are pivoted midway toward the upper end of the adjacent side wall 6a of the seedling stand 6, so that the reversing device 11 can be freely collapsed in the front-back direction. A locking part 13a is formed to hold the rear end of the replenishing seedling, and a seedling holding part 12a capable of holding the protruding rear end of the replenishing seedling is formed. One end of the replenishing seedling box 8 can be supported between the two in order to support the replenishing seedling box 8 in a floating state, and when the replenishing seedling box 8 is laid down backwards, it can hold the protruding rear end of the replenishing seedlings. This seedling loading device in a rice transplanter is characterized by the following structure: By simply reversing the reversing device 11 backward, the protruding rear end of the supplied seedlings can be reliably held and the seedlings can be prevented from being damaged.
By inverting the reversing device 11 forward, the replenishing seedling box can be pulled closer to your hand, allowing you to take out seedlings and replenish them extremely easily and quickly in a stable position. There is no fear of accidentally damaging the seedlings, and the work of replenishing the seedlings can be carried out reliably.

In addition, since the reversing device 11 has an extremely simple configuration and can be easily made into a unit, it has practical effects such as low cost and easy addition to conventional machines without changing the shape of the seedling stand 6. is also a big thing.
