Description

[Detailed Description of the Invention] The present invention relates to a row sowing device for seed rice that can sow seed rice in rows in a row so that no plants are left on the soil surface of the seedling raising box.

The applicant has already applied for Utility Model Application Publication No. 57-49311 ``Rice seed sowing device'', but the present invention is
This application is a further improvement.

This application relates to a seeding device in which an ultrasonic vibration device is connected to a groove-forming plate and seeds are sown by applying vibration to the groove-forming plate.However, when we actually tried making a prototype, we found that the rice did not flow out smoothly and the seeds floated. As a result, good seeding was not possible due to the rise and overlap of seeds.

The present invention is a rice seed row sowing device that solves the above-mentioned drawbacks, and its configuration is detailed as follows with reference to the accompanying drawings.

A large number of seedling growing boxes 3 are arranged in series on a conveyor 2 provided below the seed hopper 1, and while the seedling growing boxes 3 are transferred by the conveyor 2, the seedlings 4 are removed from the seed hopper 1.
In a row seeding device that sows rice in rows, the seed hopper 1
A frame body 7 consisting of a side wall plate 5 and a ceiling wall plate 6 is provided on the sending side of the seedling raising box.

A rotating shaft 8 is located between the side wall plate 5 of this frame body 7 near the top.
A motor 9 for the rotating shaft 8 is installed at an appropriate location on the frame 7, and a vibration transmission plate 10 is installed vertically in the middle of the ceiling wall plate 6, and a seeding roller 11 is installed at the lower end of the vibration transmission plate 10. Row seeding groove 12 located diagonally downward
The uppermost end of the grooved plate 13 is connected, and a vibration transmission gear 14 is provided at the center of the rotating shaft 8 in contact with the lower end of the vibration transmission plate 10 to apply vibration to the vibration transmission plate 10 in the front-rear direction.

The groove forming plate 13 in the drawing has mounting plates 15 at both ends of the top.
The mounting plate 15 is fixed to the lower end of the vibration transmission plate 10 with bolts and nuts.

An L-shaped contact plate 16 is provided at the center of the lower end of the vibration transmission plate 10, and this contact plate 16 is connected to the vibration transmission gear 14.
The amount of vibration is adjusted by adjusting the bending angle of this contact plate 16.

In the figure, 17 is the motor shaft, 18, 19, 20, 21
is a gear, 22 and 23 are transmission chains, 24 is a forked guide plate, and 25 is a support beam.

Since the present invention is configured as described above, the rotation of the vibration transmission gear 14 causes the vibration transmission plate 10 to intermittently vibrate in the front and back direction, so that this intermittent vibration movement (impact movement) is transmitted to the groove forming plate 13. This means that
This intermittent vibration motion is transmitted to the rice seeds 4 falling through the row sowing grooves 12 of the groove forming plate 13, so that the rice seeds 4 are sown smoothly in a line.

In other words, this intermittent vibration motion is like rhythmically hitting the top of the groove forming plate 13 with a hammer or the like at regular intervals, so the rice seeds 4 fall smoothly down the row sowing grooves 12 and are sown neatly in a single row. As a result, it is possible to provide an excellent seed rice row sowing device that improves the growth of seedlings, eliminates missing plants, and does not waste seed rice.

If the seed hopper 1 is manual, it can be switched to an automatic seeding device by obtaining power from the motor 9, and it can be used immediately by attaching the frame 7 to a conventional seeding device. It has excellent practical effects such as:
