Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a rice seeding device used for transplanting two adult rice seedlings, etc., and particularly for uniformly sowing seed rice into seedling boxes.

[Prior art]

As a conventional seeding device of this kind, the
As described in No. 27 and others, a communicating hole is opened in the double plate, the seed rice is placed in the upper hole on one side, and the lower hole is aligned with the upper hole. This is to allow the seed rice to fall through the hole.

In addition, as an improved example of the above conventional example, the upper seeding plate of the double plates that are in sliding contact is made to have a large number of holes and fine irregularities on the surface, and the seed rice is supplied to this seeding plate. Next, the sowing plate is tilted and vibrated by hand to introduce rice seeds into the holes, and the slide plate provided on the lower surface of the sowing plate is slid by hand to separate the holes opened in the slide plate and the rice seeds into the holes. There was one that aligned the holes in the sowing board with the rice seedlings and dropped the seeds into the seedling box below.

[Problem that the invention seeks to solve]

However, with such a seeding device, the seed rice is introduced into the holes by manually swinging the seeding plate, and therefore, skill is required.

In addition, it is necessary to manually insert the seeds into the holes in which the seeds cannot enter, so when sowing seeds in a large number of seedling boxes, long hours of work and labor are required. Ta.

Furthermore, at least two workers are required because there are work steps such as supplying p-seed rice to the seeding board, swinging the seeding board, sliding the slide board, and inserting and removing the seedling box into the base. , - When the work is done manually, there is a problem in that efficiency is significantly reduced.

Furthermore, if the seeds are sown while leaving holes in the holes in which the seed rice cannot enter, there is an inconvenience that plants will be missing on the bed. Particularly, in the case of mechanically planting two adult seedlings, there is a problem in that the missing plants that occur on the bed cause the machine to dry shoot, resulting in a decrease in rice production efficiency. .

[Means for solving problems]

This invention was made by focusing on such conventional problems, and consists of a seeding plate having seeding holes with a diameter that allows seed rice to enter at a number of predetermined locations, and a seeding plate that slides into contact with the lower surface of this seeding plate. and a slide plate having seed drop holes formed in the same arrangement as the seed sowing holes, and a sliding operation of the slide plate brings the holes of the seed plate into matching communication with the seed drop holes. However, in a seeding device that is installed to substantially pivot with respect to a base on which a seedling raising box is planned to be placed, a vibrating means is provided on the seeding plate, and a seed having a predetermined width is placed on the upper surface of the seeding plate. The transfer brush is horizontally suspended in the width direction of the seeding plate and is capable of reciprocating from the front end of the seeding plate to the rear end of the seeding plate, and a sliding drive means is connected to the slide plate. The configuration is as follows.

[Effect]

A predetermined amount of rice seeds supplied to the seeding plate moves along the slope while being swayed little by little due to the vibration of the vibration means in addition to the slope of the seeding plate, and reaches the numerous seeding holes made in the seeding plate. Enter each separately. At this time, the rice seed transfer brush runs on the seeding plate from the front side of the operation toward the rear side of the operation at a predetermined speed, holding back a large number of rice seeds and controlling the movement of the rice seeds along the slope.

Next, by sliding the slide plate using the sliding drive means, the sowing hole and the seed drop hole of the slide plate are communicated with each other, and the seed rice that has entered the sowing hole is dropped.

Further, the seed rice transfer brush, which has reached the rear end of the seeding plate and stopped, is moved by the traveling means to the front end of the operation and returns to its original position.

Then, the sowing function body A is horizontally placed and the seed a is placed in the seedling raising box 2.
At the same time as is dropped, the switch S is moved toward the dotted line as shown in FIG. Next, the sowing function body A is returned to the position 81, and when the seedling raising box 2 is pulled out, the switch 18 is closed, the motor 11 rotates in the reverse direction, and the brush 12 removes the surplus rice seeds from the sowing reservoir 3b. Return to position.

Furthermore, FIG. 6 shows a sliding drive means for the slide plate 6. As shown in FIG.

After confirming that the seed rice a has entered the sowing holes 3a of the sowing plate 3, the sowing function body A is horizontally covered and stacked on the base 1, and the lower end of the sowing function body A is placed on the upper end of the base 1. When the provided switch 13 is closed and the switch 14 provided at the insertion end of the seedling growing box 2 of the base 1 is pressed by the peripheral surface of the seedling growing box 2 and closed, the slide plate 6 is moved to the solenoid 1.
5, the sowing hole 3a and the rice seed drop hole 6a are slidably driven to align with each other. Note that the switches 13 and 14 are connected in parallel.

The support plate 20 includes a pair of plate pieces 20 as shown in FIG.
a and 20b are pivotally connected, and the upper ends of both plate pieces 20a and 2ob are elastically supported by a spring 21. In addition, both plate pieces 20a, 2
Semicircular notches are provided at two predetermined locations facing each other in 0b. The plate piece 20b has a support rod 2 that pushes the switching switch S at the positions sl and s2 at the positions SL and SL in the notch.
2 is 1. .

A switch S is provided. Moreover, each SL is provided protruding from the side of this water sowing frame 4.

This is to support the seeding function body A at the position of Sl.

The operation of the vibrating means of the seeding plate 3, the traveling means of the nine types of paddy transfer brush 12, and the sliding drive means of the slide plate 6 will be explained below along with the operating procedure of the seeding device.

First, the seed rice a is supplied between the seed rice transfer brush 12 located on the front side of the upper surface of the seeding plate 3 and the seeding frame 4. At this time, the seeding function body A is held at the position 82 of the support plate 20.

The sowing function body A to which the seed rice a has been supplied moves to the position Sl by lifting the handle 5, and the switch 9 is closed, input is input to the motor 7, and the sowing plate 3 is vibrated.

At the same time, the switch 16 of the rice seed transfer brush 12 is closed, the motor 11 is turned on, and the brush 12 runs at a predetermined speed from the front end to the rear end. Here, the brush 12 slides the seed rice a along with its travel while suppressing the free fall of the seed rice a, and reaches the rear end of the operation. Then, along the way, each nine grains of rice a vertically enter into the seeding hole 3a as a result of the vibration. At this time, the seed rice falling hole 6a of the slide plate 6 is shifted from the seeding hole 3a, so the seed rice a
is held in the seeding hole 3a.

When the rice seed transfer brush 12 reaches the rear end of the sowing plate 3, the switch 17 is released by the brush 12, and the motor 11 is stopped.

Next, the sowing function body A with the seed rice in the sowing hole 3a is manually lowered to the position S2, the sui-nochi 9 is released, and the vibration is stopped.

The seedling raising box 2 is inserted into the base 1 below the sowing function body A, which is ready for sowing, from the side before operation, and the switch 14 is closed. At this time, since the seeding function body A is in the S2 position, the switch 13 is still released and the circuit of the solenoid 15 is in an open state.

Next, when the seeding function body A is placed horizontally on the base 1 on which the seedling raising box 2 is placed, the switch 13 closes and the solenoid 1
5 is input, and the slide plate 6 is pulled against the resilient spring, so that the sowing hole 3a and the rice seed drop hole 6a are aligned and communicated, and the rice seeds are dropped onto the upper surface of the floor of the seedling raising box 2.

When the seedling raising box 2 in which seeding has been sown is pulled out from the base 1, the slide plate 6 is returned to its original position by a spring.

Next, when the sowing function body A is manually returned to the position S2, the switch S changes from the state shown in FIG. 4 to the state shown in FIG. The brush 12 returns to its original position (the end before operation).

At this time, the brush 12 carries the surplus rice seeds a back to the original position. Here, since the sowing plate 3 is not vibrating, the seed rice a does not enter the seed hole 3a very much, but even if it does, there is no problem because the above operation will be repeated the next time the seed rice a is supplied.

In this state, the next supply of seed rice is again possible, and continuous sowing is performed.

In the above embodiment, means as shown in FIGS. 8 and 9 are planned as means for supplying the seed rice.

That is, a hopper 25 having a supply port 25a having a length that is approximately the same as the width of the seed plate 3 is installed above the front end of the seed plate 3, and the opening of the supply port 25a has a substantially U-shaped cross section. rotating container 2
7 is rotatably provided along the longitudinal direction of the vaginal opening 25a, and a predetermined amount of rice seeds can be supplied to the sowing plate 3 by rotating the container 27. A pinion 28 coaxial with the rotating container 27 is fixed to one end of the rotary container 27, and this pinion 28 is meshed with a rack rod 26 erected at a predetermined position of the seeding function body A. It is also possible to supply seed rice from the container 27 to the seeding plate 3 by raising and lowering A. In particular, according to the above embodiment, the sowing function body A moves up and down cyclically in accordance with the operating procedure, and is therefore suitable for supplying rice seeds by the rotary container 27.

In addition, in the above embodiment, various operations of the sowing function body A,
Each drive means is automatically operated by the operation of taking in and out the seedling raising box 2, and each drive means is equipped with a manual slide plate control switch 31, a seed transfer brush switch 32, and so on. Ti type plate vibration switch 33. Of course, it is also possible to provide and use an automatic-manual changeover switch 34.

Further, the sliding drive means includes arm rods 29, 2 which are pivotally supported on the free end of the iron core 15a of the solenoid 15, as shown in FIG.
9 is pivotally supported at a fulcrum so as to be divided into arms with a predetermined ratio of moments, and the force of the solenoid 15 is doubled with a boosting effect.
It is also possible to ensure the sliding movement of the slide plate 6.

In addition to the embodiments described above, considerable design changes are planned in accordance with the gist of the configuration of the present invention.

〔Effect of the invention〕

As explained above, in this invention, the seed rice transfer brush runs on the upper surface of the seeding board from the front end of the sowing plate to the rear end thereof at a predetermined speed while blocking the rice seed with the brush, so that the seed rice is reliably sown. guided over the hole. In addition to this, the seed plate vibrates, making it possible to reliably feed the rice seeds into the seed holes.

By ensuring that the rice seeds are inserted into the seeding hole in this way, when the seeds are sown on the bed, no plants will be missing.
It has the effect of further increasing production efficiency.

In addition, by automating the operation of various means such as the vibration of the sowing plate, the sliding of the slide plate, and the reciprocating movement of the nine types of paddy transfer brushes, it is now possible for one person to perform sowing work, and the time required per round is reduced. This has the effect of shortening the time, making continuous sowing work easier, and reducing worker fatigue associated with sowing work.
