Description

[Detailed description of the invention] This invention relates to a preliminary seedling placement device for a rice transplanter in which a seedling transplanting body is attached to a running vehicle body.More specifically, the seedling scooping plate for scooping plate-shaped seedlings with soil is moved as it is. This is a device that is placed on the vehicle body, and storing the seedlings while scooping them out on the seedling scooping plate like this is very convenient when supplying seedlings to the seedling tank on the side of the seedling planting machine. Although this enables quick supply, on the other hand, it is easy for the seedbeds on the seedbed scooping plate to slip off due to the vibrations of the aircraft or the rotation of the aircraft.

The purpose of this invention is to enable easy feeding of seedlings to a seedling tank and to eliminate the above-mentioned drawbacks.

This invention will be explained in detail based on an embodiment shown in the drawings. Reference numeral 1 is a traveling vehicle body, which is not a special structure but has the structure of a well-known tractor. 2
indicates the rear wheels, and 3 indicates the cockpit.

Reference numeral 4 denotes a rice transplanting machine, in which a float 6 for leveling the ground is provided at the bottom of a frame 5, and a seedling tank 7 is attached to the top so that it can reciprocate from side to side at a constant speed, with the rear section being lower and the front section being upper. A seedling cutting device 8 is mounted opposite to the rear lower end for dividing the seedlings in the seedling tank 7 and transplanting them into the soil leveled by a float 6.

This rice transplanting machine body 4 is attached to the rear of the traveling vehicle body 1 via a four-point linkage mechanism 9 so that the rice transplanting machine body 4 can be adjusted up and down. 10 is its lifting hydraulic cylinder.

Reference numeral 11 denotes a spare seedling stand, which is supported on the traveling vehicle body 1 by a front support rod 20 that rotates back and forth, and a rear support rod 21 that rotates back and forth at the same time as it expands and contracts up and down, and is supported by a hydraulic device to support the rear side. When moving in the direction of arrow A, the rear end of the rice transplanting machine body 4 is provided on the frame body 12, which gradually moves downward and approaches the upper end of the seedling tank 7 of the rice transplanting machine body 4, as follows. That is, the preliminary seedling stand is constructed via link rods 14a and 14b whose bases are pivotally mounted on the frame 12, and the link rods 1
4a is always resiliently supported forward by a spring 15 and is abutted against a stopper 16 to be locked in a predetermined state.

In the illustrated example, the support stand 11a of the preliminary seedling stand 11 is formed of a wire rod, and in the embodiment shown in FIG. The side support shaft 18 is provided in the upper position, and in another embodiment shown in FIG. 3, the support shafts 17 and 1
8 are made the same height and the rear ends of the wire rods are bent upward.

Reference numeral 22 designates a seedbed scooping board, which is made of a thin plate having a rectangular shape in plan view, and has a handle portion 24 on the base side with an erected wall that also serves as a stopper 23 for the seedbed, and a support for the preliminary seedling platform 11 on the back side. Locking body 2 that engages with shaft 17
5 is set.

In the configuration of the above example, the seedling tank 7 is loaded with plate-shaped seedlings A with soil scooped out from a seedling box (not shown) in which seedlings have been grown using the seedling scooping plate 22, and the preliminary seedling loading table 1
A seedbed scooping plate 22 with seedbeds scooped out from a seedling box is mounted on the top of the seedbed scooping plate 22 with a locking body 25 on the back side thereof being locked to a support shaft 17.

At this time, since the tip side of the seedbed scooping plate 22 is located higher than the base side, there is no possibility that the seedbed on the seedbed scooping plate 22 may accidentally slide off even if the traveling vehicle body 1 swings up and down or turns. It is maintained stably without any damage.

When each part of the rice transplanting machine body 4 is driven in the field while moving the traveling vehicle body 1 forward, the seedling tank 7 moves back and forth to the left and right, and the seedling cutting device 8, which moves up and down from its lower end side, feeds one plant at a time. supply seedlings,
The seedling cutting device 8 plants the seedlings on the leveled soil surface using the lower float 6.

In this way, the seedlings are planted and the seedling tank 7
When the number of seedlings inside is reduced and replenishment is required, the traveling vehicle body 1 is stopped and the hydraulic device (not shown) is used to rotate the front support rod 20 in the direction of the arrow A and retract the rear support rod 21, causing the frame body 12 supporting the spare seedling carrier 11 to tilt while slowly moving backward. The system is set in this tilted state, but at this time, the soil-covered plate-shaped seedlings A placed on the spare seedling carrier 11 via the seedbed scooping plate 22 are not yet in a state where they slide off.

Therefore, the operator
When you grasp it and push it backwards against the spring 15, the link rods 14a and 14b rotate backwards, and the tip of the seedbed scooping plate 22 is securely pushed into the seedling tank 7 of the seedling planting machine 4.
Approach the top. Then, when the operator subsequently lifts the handle 24 and tilts the scooping plate 22 greatly, the plate-shaped seedlings A with soil placed thereon slide into the seedling tank 7 and are reliably supplied. When the supply is finished, each support rod 20, 21 is returned to its original position using the hydraulic system, and the seedling planting work is preferably started again.

In this invention, a seedling inserting device 8 is installed at the rear of the traveling vehicle body 1.
A seedling planting device 4 having a seedling tank 7 and a seedling tank 7 is installed in a tilted manner so that the front of the seedling tank 4 is located above the traveling vehicle body side, and is attached to the upper rear side of the traveling vehicle body 1.
A preliminary seedling mounting stand 1 on which a seedbed scooping plate 22 having a handle part 24 on the base end side and a stopper 23 rising upward is placed so that the handle part 24 side stands in front.
1, this preliminary seedling loading stand 11 is installed on the traveling vehicle body 1.
It is provided on the top so that it can be oscillated between the front upper position and the rear lower position through the front and rear link rods 14a and 14b, and at least:
When the preliminary seedling platform 11 is set at the upper front side, when the seedbed scooping plate 22 is supported, the rear side is supported at a higher position than the front side, and it is set at the lower rear side. In this case, since the preliminary seedling mounting device in the rice transplanter is configured in such a manner that the support stand 11a is provided so that the rear end of the seedling bed scooping plate 22 is located largely behind the front end of the seedling tank 4, The seedlings A can be reliably loaded and held while being scooped with the seedling scooping plate, and will not fall off even when the aircraft vibrates or turns. Moreover, when feeding the seedlings to the seedling tank, By swinging the scooping plate through the link, the rear end of the scooping plate can be positioned further to the rear than the front upper end of the seedling tank and fed. Compared to those in which the seedlings are fed into the seedling tank, the seedlings do not suddenly collide with the seedlings remaining in the seedling tank, damage to the seedlings can be reduced during feeding, and the seedlings can be quickly and easily fed into the seedling tank.

In addition, in the embodiment, a configuration may be adopted in which a spare plate-shaped seedling A with soil can be placed on the upper surface of the frame 12 itself.
