Description

[Detailed description of the invention] The present invention is equipped with a seedling stand that moves back and forth from side to side, and a planting claw that takes out and plants one seedling from this seedling stand, and the seedlings that are placed on the seedling stand. In other words, the present invention relates to a seedling mounting table device for a rice transplanter that incorporates a seedling vertical feeding device that vertically feeds the seedling mat toward the seedling take-out side at the left-right movement end position of the rigging.

According to the present invention, the vertical feed wheel that bites into the seedling mat H when it is fed and the brake wheel that bites into it when the seedling mat H is stopped are arranged side by side on the seedling platform. When vertically feeding the pine, the vertical feeding foil allows the vertical feeding of the seedlings to be carried out smoothly, thereby reliably preventing the seedlings from being damaged due to poor seedlings or falling apart, or from poor planting posture of the seedlings. When the mat is stopped, the brake wheel is used to ensure that the seedlings are stopped, thereby preventing the remaining seedling mats from being scraped by the planting claws or being crushed while the seedling platform is moving from side to side. ,
To provide a seedling mounting stand device for a rice transplanter which makes the seedling scraping residue of the planting claw uniform, stabilizes the posture of the seedling scraped by the planting claw, and achieves good planting of the seedlings.

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 is a schematic side view of a rice transplanter, in which 1 is an engine, 2 is a transmission case, 3 is a planting transmission case, and 4 is a paddy wheel supported on the side of the mission case 2 via a swing case 5. , 6 is the engine 1 and each case 2
, 3, a floating sliding body that supports the machine body through a planting depth adjustment link 7 and a buffer member 8; 9, a steering handle connected to the rear end of the transmission case 3; 10, a steering handle connected to the rear end of the transmission case 3; A seedling stand 11 is provided along the upper part of the handle 9 and has a low front and back height and is moved back and forth from side to side. A seedling stand 11 is attached to the transmission case 3 via a crank arm 12 to take out one seedling from the seedling stand 10. This is a planting claw that is used for planting seedlings, and is configured to perform continuous seedling planting work.

Further, a guide rail 13 is fixed to the middle lower surface of the seedling stand 10, and a support 14 is erected in the waist planting mission case (3).
A slider 15 provided on the case 3 is slidably inserted into the rail 13, and a bracket 16 is fixed to the lower surface near the inclined lower end of the seedling platform 10, and the seedling platform lateral feed shaft provided in the case 3 is attached. The bracket 16 is connected to the seedling stand 17, and the inclined lower end of the seedling stand 10 faces the guide rail 18, and the seedling stand 1
0 is formed so as to slide back and forth to the left and right in conjunction with the planting claws 11.

In addition, a cam 20 for vertically feeding the seedlings is fixed to a horizontally feeding recam shaft 19 that reciprocates the horizontally feeding shaft 17 of the seedling platform 17, and a seedling vertically feeding mechanism is provided on the lower surface of the seedling platform 10 near the inclined lower end thereof. A vertical feed wheel 21 and a brake wheel 22 are incorporated.

The foils 21 and 22 are arranged in two rows, upper and lower, as shown in FIGS. 2 and 3, and are attached with their claws facing in different directions, and the vertically feeding foil 21 is attached to the seedling mat Act.
The brake wheel 22 is provided so as to effectively bite into the seedling mat A when feeding the seedling mat A, and also to make the brake wheel 22 effectively bite into the seedling mat A when the seedling mat A is stopped.

Further, a driven cam 24 is provided coaxially with the brake wheel 22 via a one-way clutch 23, and a swing arm 26 is provided coaxially with the longitudinal feed wheel 21 via a one-way clutch 25. A return spring 2 that interlocks and connects the arm 26 with a link 27 and causes the swinging arm 26 to move the arm 26 and the cam 24 back.
8 is attached, and when the seedling platform 10 reaches the end of left-right movement and moves back in the opposite direction, the seedling vertical feed cam 20 is brought into contact with the driven cam 24, and the cam 24 is moved against the spring 28. The arm 26 is configured to be rotated via the link 27 at the same time as the arm 26 is rotated.

When the swing arm 26 and the driven cam 24 are rotated backward by the spring 28, the vertical feed wheel 20 and the brake wheel 22 are rotated via the one-way clutches 25 and 23, respectively, and the seedling stand 10 is rotated. The seedling mat A is placed on the seedling stand 10 by its foils 21 and 22.
The seedlings are fed out to the lower end of the slope, that is, to the side from which the seedlings are taken out.

The present invention is constructed as described above, and under the condition shown in FIG.
By moving the planting claw 11 back and forth from side to side and moving the planting claw 11 in a planting cycle, the planting claw 1 can be moved from the seedling stand 10
1, one seedling is taken out and planted in the field one by one, and when the seedling platform 10 reaches the end of left and right movement and turns back, the vertical seedling feed cam 20 moves to the driven cam 24 as shown in FIG.
and rotates the cam 24.

Further, when the cam 24 rotates, the swing arm 26 is simultaneously rotated via the link 27.

Then, the seedling vertical feed cam 20 comes out of contact, and the spring 2
When the swing arm 26 and the driven cam 24 move back by 8, the vertical feed rewheel 21 and the brake wheel 22 rotate via the one-way clutches 25 and 23, respectively, and the seedling mat A is moved to the lower end of the slanted seedling stand 10. It slides down to the side.

When the seedling mat A slides down, the claw teeth of the vertical feed foil 21 effectively bite into the seedling mat A and facilitate the sliding movement of the seedling mat A. On the other hand, when the seedling mat A stops, The claw teeth of the brake wheel 22 effectively bite into the seedling mat A to more reliably stop the seedling mat A and maintain its position.

FIG. 5 shows another embodiment, in which the vertical feed wheel 21 is in the upper row and the brake wheel 22 is in the lower row.
In this structure, the longitudinal rewheels 21 and brake wheels 22 are arranged alternately in two rows, upper and lower, in a staggered manner.

Furthermore, FIG. 6 shows another embodiment of the above-mentioned embodiment, in which the longitudinal rewheel 21 and the brake wheel 22 are arranged alternately in a line on the lower end side of the slope of the seedling stand 10. It is something that

These have the same functions and effects as those of the previous embodiment, and detailed explanation thereof will be omitted.

As is clear from the above examples, the present invention is applied to seedlings of pine)A.
Since the vertical feed foil 21, which bites into the seedling mat during vertical feeding, and the brake foil 22, which bites into the seedling mat A when it is stopped, are arranged in parallel on the seedling platform 10, it is possible to In this case, it is possible to smoothly move the seedlings vertically by using the vertical rewheel 21, and it is possible to reliably prevent missing plants or poor planting posture of the seedlings caused by poor seedling slippage or collapse of the seedlings. When the mat A is stopped, the seedlings can be reliably stopped by the brake wheel 22, and the remaining seedling mat A that has already been scraped off by the planting claws 11 while the seedling platform 10 is moving from side to side.
It is possible to prevent the seedlings from slipping or crumbling, thereby making the seedling scraping residue of the planting claws 11 uniform, stabilizing the posture of the seedlings being scraped by the planting claws 11, and achieving good planting of the seedlings. It has the effect of
