Description

[Detailed Description of the Invention] The present invention relates to an improvement of a seeding machine, particularly a seeding machine that scatters rice seeds in a seedling box for raising mat-shaped seedlings to be loaded into a rice transplanter.

The seeding machine is installed astride a conveyor, and this conveyor is used to sequentially feed a large number of seedling raising boxes below the seeding machine, and the seed rice that is discharged from the seeding machine is scattered into the seedling raising boxes. According to a seeding machine that is used to automatically drop and discharge the first type of paddy, the seeded rice is continuously discharged from the sowing machine regardless of whether or not there is a seedling box below it. Therefore, the seed rice falls between the seedling boxes that are fed one by one, and there are problems such as not only the seed rice is wasted but also the conveyor may become clogged, resulting in subchapter. Ta.

The present invention was developed in view of the above circumstances, and its purpose is to provide a seeding machine that allows seed rice to be sown only when a seedling nursery box moves below the seeding machine, and includes the following: The present invention will be described in detail based on drawings showing embodiments thereof.

In Fig. 1, R indicates a roller conveyor, and the seeding machine according to the present invention (hereinafter referred to as the present product) straddles the path through which the seedling boxes P-P are fed by the roller conveyor R in the direction of the white arrow. It is fixed in this way.

Therefore, in this product, a pedal-shaped lever is provided on the inner surface of one of the side legs 2a and 2b, which supports the hopper 1 (not shown) in which seed rice is to be stored, on the inner surface opposite to the other side leg 2b. 3 is pivotally supported, and one seedling raising box P is fed so that the side end of the bottom surface presses against the upper surface of the lever 3.

As shown in FIG. 2, the hopper 1 has a discharge port 1a formed at its lower end like a known seeding machine.The seeding roll 4 is mounted on an axis in the direction of the side legs 2a and 2b so as to block the discharge port 1a. 1, and can be rotated in the direction of the arrow by a driving means (not shown).

A brush 5 for suppressing seed discharge that rubs against the surface of the sowing roll 40 is attached to the front edge of the discharge port 1a. The seed rice fitted into a recess (not shown) formed on the circumferential surface is allowed to fall and be discharged.

Furthermore, one tip portion slides on the circumferential surface of the seeding roll 4, and the base end portion is attached to the inclined back surface of the hopper 1 so as to be tilted forward, and the recess formed on the surface of the seeding roll 4 when the seeding roll rotates 40 times and its tip end. The diaphragm 6 is provided with a diaphragm 6 that swings up and down about the base end when engaged with the base end.

FIG. 3 is a plan view showing the engaged state of the diaphragm 6, the shutter γ and the drive plate 8 disposed above and below the diaphragm, and the wire 9 connecting the drive plate 8 and the lever 3. It is a drawing.

Both ends of the chanterf are placed on angled guide rails 10°10 provided on the inner surfaces of both side walls of the hopper 10, and the shantuff is guided by these guide rails 10°10 so that it can move back and forth. .

The length of the shutter 7 is longer than the longitudinal dimension of the discharge port 1a, and when the shutter 7 moves forward, it closes the discharge port 1a above it, and when it moves backward, it closes the discharge port 1a.
The length is such that it can be opened.

A bottle 11 is fixed downwardly to the lower surface of the shutter 7 at approximately the center thereof, and this bottle 11 has an elongated hole 6a extending in the front-rear direction, which is formed at the approximately center of the sliding plate 6. It is inserted through a guide hole 8a formed in a drive plate 8 disposed below the diaphragm 60.

This drive plate 8 is a sowing roll 40 on the diaphragm 60 side.
It is supported so as to be slidable laterally so as to fit into angled guide rails 12, 12 which are mounted parallel to each other in the front and back at a position that does not hinder rotation.

As shown in FIG. 3, the guide hole 8a has a four-dimension plane with respect to the front or rear edge of one discharge port 1a so that its long side direction goes from the rear of the side leg 2b to the front of the side leg 2a. It is set in the rotated direction.

The end of the drive plate 8 on the side leg 2a side is connected to a wire 9 that is hung on a pulley 13, and the other end of this wire 9 is connected near the tip of the lever 3. The other end of a spring 14 fixed to the inner wall surface of the hopper on the side leg 2b is connected to the end of the leg 2b.
The tip is urged to be pulled upward.

With such a configuration, the bottle 11 whose upper end is fixed to the lower surface of the shutter 7 allows the drive plate 8 to move only in the front-rear direction when it moves in the direction of the side legs 2a.
When the shutter 7 is pressed by the front edge of the shutter and moved backward, the shutter 7 also moves backward, and conversely, when the drive plate 8 moves toward the side leg 2b, the shutter 7 moves forward, contrary to what was described above. It is supposed to move.

Therefore, the amount of movement of the chanterf is determined by the long side dimension of the guide hole 8a, and the long side dimension is such that when the chanterf moves backward, the discharge port 1a is opened and the shutter 7 does not interfere with the discharge of the seed rice. Further, when the shutter 7 moves forward, the length is set to allow the shank 7 to move enough to close the discharge port and prevent the shutter 7 from discharging the seed rice.

Also, for the same purpose, the long hole of the diaphragm 6 has a cos 4 of the long side dimension of the guide hole 8a! It is more than le times.

Note that the mechanism for converting the movement of the drive plate 8 in the direction of the side legs 2a, 2b into the movement of the chanterfe in the front-rear direction is not limited to the above-mentioned embodiment, and any suitable mechanism may be used.

The product configured as described above operates as follows.

That is, the seedling boxes P containing soil are sequentially fed to the product by the roller conveyor R at appropriate intervals.

Now, when the - number of seedling growing boxes P reach below the discharge port 1a of the main body 1 of the present product, the seedling growing boxes P pass through the location where the lever 3 is disposed so as to ride on the lever 3.

Therefore, as shown by the solid arrow, the lever 3 is pressed against the side edge of the bottom of the seedling box P and rotates downward against the pulling force of the spring 14, thereby pulling the wire 9 in the direction of the lever 3. As a result, the drive plate 8 moves in the direction of the side leg 2a,
Shantahu moves backwards and retreats as described above.

On the other hand, one seeding roll 4 is rotationally driven, and the diaphragm 6 swings up and down together with the drive plate 8 to evenly guide the seed rice in the hopper 1 toward the tip of the diaphragm 6.

Since the shutter 1 is moved back as described above and the discharge port 1a is open, the first type of paddy fits into the recess on the circumferential surface of the seeding roll 4, and enters the seedling box from the gap between the brush 5 and the surface of the seeding roll 40. fall towards.

That is, while the seedling raising box P passes through the location where the lever 3 is provided, the shutter 1 opens the discharge port 1a and the seed rice is sown.

Now, from the time the seedling box P passes past the location where the lever 3 is placed until the next seedling box P arrives, the lever 3 and the driving plate 8 are pulled by the spring 14 as shown by the broken line arrow. The lever 3 rotates upward and the drive plate 8 moves toward the side leg 2b.

Then, the bottle 11 is pressed by the rear edge of the guide hole 8a and moves forward, and accordingly, the shutter 1 also moves forward and the discharge port 1a is closed above the seeding roll 4.

Therefore, during this time, the seed rice cannot fit into the recess on the circumferential surface of the seeding roll 4, and the seed rice is not unnecessarily discharged onto the roller conveyor R where the seedling raising box P is not present.

When the succeeding seedling box P is fed to the location where the lever 3 is disposed, the chanterf opens the discharge port 1a again as described above, and sowing to the seedling box P is started.

As described in detail above, according to the present product, when the seedling box P is not located below the location of the lever 3, that is, the discharge port 1a, the discharge of the seed rice is prevented, so that the wasteful consumption of the first type of rice is avoided. This method is particularly effective when a large number of seedling boxes P are sent and the seeds are sown.

Since the rice seeds are not scattered on the roller conveyor R, there is no possibility that the roller conveyor R will be clogged and the smooth feeding of the seedling box P will be hindered or that it will malfunction.

In the above-mentioned embodiment, the seeding machine was fixed and the seedling growing boxes were moved, but on the contrary, the seedling growing boxes were fixed in rows and the seeding machine was moved by itself along the rows of these seedling growing boxes. It goes without saying that the present invention can also be applied to such cases.

In that case, it is appropriate that the lever, which is activated when it detects that the seedling box is located below the outlet of the hopper, be configured so that it comes into contact with the upper edge of the side wall of the seedling box and operates.
