Description

[Detailed Description of the Invention] The present invention relates to a seedling feeding device for a rice transplanter, which is equipped with a conveyor belt provided on the bottom of a seedling stand for sequentially feeding the placed pine-shaped seedlings to the lower seedling take-out side.

In order to enhance the seedling feeding function of the seedling feeding device configured as described above, a large number of protrusions or protrusions are formed on the conveyor belt, and the protrusions or protrusions are arranged to protrude from the upper surface of the seedling tray. is normal.

This seedling feeding device uses a large number of protrusions or ridges to feed the seedlings, so the seedlings can be fed reliably. There was a problem in that the sliding movement was obstructed, and the work required to feed the seedlings while lifting them was time-consuming, and the feeding of the seedlings tended to be uncertain. and,
Immediately after the start of work, the feeding of seedlings tends to be uncertain, resulting in missing plants because the lower ends of the seedlings do not fully reach the seedling removal section, and during work, the lower ends of the seedlings may This had the disadvantage of causing missing plants due to the lack of close contact with the top of the seedlings.

The present invention has been made in view of the above-mentioned problems, and it is an object of the present invention to provide a seedling feeding device that can smoothly feed seedlings when feeding or replenishing seedlings by rationally modifying the seedling feeding device. have a purpose.

A feature of the present invention is that the conveyor belt is configured to be retractable from the bottom of the seedling stand toward the lower side of the upper side of the conveyor, and its effects are as follows.

In other words, since the conveyor belt is configured to be retractable as described above, when feeding or replenishing seedlings, the seedlings are less likely to be obstructed by the protrusions of the belt, and the feeding of the seedlings becomes smooth. In addition, if the conveyor belt is moved to the seedling feeding position after the seedlings have been fed, that is, above the lower side of the seedling conveyor, this movement includes a component that moves the seedlings along the bottom of the seedling table and toward the lower side of the conveyor. It moves in this direction together with the conveyor belt.

Therefore, when supplying seedlings before the start of work or during supply of seedlings, the conveyor belt can be retracted to smoothly feed the seedlings, and after feeding the seedlings, the conveyor belt can be moved to the seedling feeding position and set. By doing this, the lower end of the seedling is reliably sent to the seedling take-out unit, which prevents the occurrence of missing plants immediately after the start of the planting process, and similarly, the lower end of the seedling is in close contact with the upper end of the previously supplied seedling, so it can be easily removed during the planting process. stock shortages are less likely to occur. In other words, with the simple structure of configuring the conveyor belt so that it can be retracted diagonally as described above, the normal seedling feeding function is not impaired, and the feeding of seedlings can be done smoothly without any hassle, and it is difficult to cause missing plants. A seedling feeding device has now been provided.

Hereinafter, embodiments of the present invention will be described based on the drawings.

As shown in Fig. 1, a transmission case 2 is driven from a passenger aircraft (not shown) via a transmission shaft 1, and a plurality of planting cases 3 extend rearward from the transmission case 2. A plurality of seedling planting mechanisms 4 attached to the rear end..., a seedling stand 5 that is movable from side to side on the top of the planting case 3 and can hold pine-shaped seedlings W, and a seedling platform 5 that swings downwards of the planting case 3. The seedling planting section, which is composed of a plurality of floats 6 that are freely attached to each other, and mulch arms 7 that press the mud on the left and right sides of the planted seedlings, is attached to the passenger aircraft via a link mechanism 8. It is installed so that it can be moved up and down.

At the bottom of the seedling table 5, a seedling feeding device B for feeding the pine-shaped seedlings W in the direction of the lower seedling take-out section A is provided for each row with the following structure.

That is, as shown in FIGS. 2 to 5, a bracket 9 is attached to the lower part of the bottom surface 5a of the seedling stand on which the pine-shaped seedlings W are placed. Two elongated holes 9a and 9b are vertically bored in the direction approaching the bottom surface 5a. A support shaft 10 is inserted through the upper elongated hole 9a, and a pulley 11 is rotatably supported on each shaft of the support shaft 10. Further, a drive shaft 12 is inserted into the lower elongated hole 9b, and four star-shaped foils 1 are inserted into each strip.
3... is installed. And pulley 11
and a through hole 14a that the foils 13, 13 can engage with, and a large number of protrusions 14b that lock and send the pine-shaped seedlings W.
... (an example of a protrusion) is wound around the rubber belt 14. Then, the support shaft 10, the drive shaft 1
2. The pulley 11, the foil 13, and the belt 14 are referred to as a seedling feeding device B.

As shown in FIGS. 1 to 3, in the seedling feeder B, the drive shaft 12 is urged downward by the spring 15, so that the protrusions 14b of the belt 14 protrude from the bottom surface 5a of the seedling tray. It is maintained and exhibits normal seedling feeding function. The support shaft 10 is connected to a lever 17 attached to the back side of the seedling tray 5 via a wire 16, and by operating the lever 17 from the normal seedling feeding position X to the retracted position Y, the seedling feeding device B is activated. moves along the elongated holes 9a and 9b, and the protrusion 14b
The tip of the ... is approximately at the same level as the bottom surface 5a of the seedling stand, so that the pine-shaped seedlings W can be fed smoothly.

Also, after the pine-shaped seedling W is sent in, the lever 17
By returning to the X position, the pine-shaped seedling W is slightly sent toward the seedling take-out section A. Note that 18 in the figure is a sensor that detects when the remaining amount of seedlings on the table has fallen below a certain level.

When planting seedlings, the soil gathering arm 7 presses the muddy soil at the base of the seedlings from the left and right to form a space around the roots of the planted seedlings to prevent moisture from evaporating and maintain the planting posture of the seedlings. This will be explained based on FIGS. 1, 6, and 7.

The shoring arm 7 is composed of a pair of left and right plate-like bodies 7a, 7a for each strip, and its base end is attached to the swing shaft 19. The swing shaft 19 is connected to the seedling planting mechanism 4.
It is driven in conjunction with the drive of , and presses the mud surface D immediately after planting the seedlings. The plate-like bodies 7a, 7a are bent so that their tips taper downward, and close the spaces E formed on the right, left, and above sides of the seedling Wa immediately after planting, and the lower edges 7 of the plate-like bodies 7a, 7a.
A and 7A are designed to press mud while feeding it in the direction of the seedlings Wa.

In this embodiment, the seedling feeding device is configured to retract along the elongated hole, but in the present invention, instead of this, the seedling feeding device is configured to be retracted and moved through a swing arm, a link function, etc. You may also configure
By effectively utilizing this configuration, the amount of protrusion of the conveyor belt relative to the seedling stand may be adjustable.
