Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Field of Application) The present invention relates to a seeding device for seedling raising boxes that is used for both row sowing and sowing.

(Prior art) The conventionally known Japanese Utility Model Publication No. 48-21 discloses a seed feeding device having a seed feeding hopper and a horizontal shaft feeding roll that feeds out the seed rice in the hopper, and a seedling raising box that can be horizontally transferred in the front and back direction. A device equipped with a transfer table is described.

Furthermore, the conventionally known Japanese Utility Model Application Publication No. 55-69909 describes a paddy guide having a split drop opening attached to the lower part of the horizontal axis feed-out roll using a parallel link rod.

(Problems to be Solved by the Invention) None of the above-mentioned known examples are seeding devices that can be used for both row seeding and sowing. A paddy guide is required when row-sowing to a seedling-growing box, but a paddy guide is not required when sowing to a seedling-growing box. When attaching a paddy guide to a seedling raising box for row sowing, it is necessary to raise the seed rice supply device high enough to attach the paddy guide. When sowing into a seedling-growing box, if the seed feeding device is set high as in the case of row sowing, the seed feeding device will be too high and the seedlings will be scattered outside the seedling-growing box.

The present invention allows the seed rice supply device to be adjusted by a simple means from a high position where a paddy guide is attached to a low position where a paddy guide is not attached.

(Means for Solving the Problem) Therefore, the present invention provides a seed supplying device 2 having a seed supply hopper 1 and a horizontal shaft delivery roll 6 for delivering the seeds in the hopper 1, and a seedling raising box that is horizontally transferred in the front and back direction. A support member 20 is fixed to the transfer table 14, and the lower ends of a pair of front and rear parallel link rods 16, 16, which rotate at an angle to the support member 20, are connected by shafts 21, 21. The upper ends of the parallel link rods 16, 16 are fixed to the shaft 1.
7 and 17, the supporting member 20 is provided with a plurality of engaging portions 26 centered around the shaft 21, and the seed rice supplying device 2 is provided with a shaft. This seeding device for seedling raising boxes is equipped with an engaging body 24 that selectively engages with an engaging part 26, and a paddy guide 27 with a split drop opening 29 is removably attached to the lower part of the horizontal axis feeding roll 6. That is.

(Example) An example of the present invention will be described with reference to the drawings.
is a seed supply hopper of the seed supply device 2, 3 and 4 are grain flow plates, 5 is a flow outlet, and 6 is a horizontal shaft delivery roll,
In this embodiment, it is formed by horizontal axis feeding rolls in the left and right direction. Horizontal grooves 7 parallel to the generatrix direction are formed on the outer circumferential surface of the horizontal axis feed roll 6 at desired intervals, and slits 8 are formed on the entire circumference at desired intervals in the left-right direction. It will be done. The depth of the slits 8 is formed slightly deeper than the horizontal grooves 7, and each slit 8
The scraping body 9 is fitted into the.

Above the horizontal axis feeding roll 6, there is a leveling/awning machine for sweeping back and leveling the seed rice 10 that is not fitted into the horizontal grooves 7 of the horizontal axis feeding roll 6, and for carrying and taking out the seed rice with awns. A rice grain removal brush 11 is provided. 12
13 is a seed guide plate that is in contact with the side surface of the horizontal feed roll 6, and 13 is a sponge provided inside the seed guide plate 12.

Thus, the rice seed supply device 2 is attached to the transfer table 14 for horizontally transporting the seedling raising box so that its height can be adjusted freely so that it can be switched between row sowing and scattering.

That is, the rice seed supply device 2 is the rice seed supply device 2.
The height position can be switched between when the entire seed supply device 2 is located at the upper position T and used for row sowing, and when the entire seed supply device 2 is located at the lower position t and used for dissemination. It is installed in such a way that it can be finely adjusted so that it can be used even in seedling boxes with a height of .

At the lower ends of the left and right side plates 15 of the seed rice supply device 2, the upper ends of inclined rods 16, 16 are connected to shafts 1 and 16, respectively.
7, 17 for pivoting. The lower ends of the inclined rods 16, 16 are pivoted to support members 20 mounted on each frame 19 of the transfer table 14 by shafts 21, 21.
Therefore, the seed rice supply device 2 has the inclined rods 16,1
6 moves diagonally up and down by rotating around the shafts 21, 21 like parallel links.

An L-shaped support fitting 22 is fixed to the front side of the side plate 15 when viewed from above, and an upwardly U-shaped mounting fitting 23 is attached to the support fitting 22. Mounting bracket 2
3 through which the left-right direction inlet/outlet member 24 is inserted and retracted freely. A spring 25 is wound around the outer circumference of the removable member 24, and the spring 25 biases the tip of the removable member 24 so as to protrude outward from the support fitting 22.

At the front end of the support member 20 on the side where the inlet/outlet member 24 is provided, a number of engaging portions 26 with which the inlet/outlet member 24 engages are formed. The engaging portion 26 is connected to the inclined rods 16, 16.
This is formed in the moving path of the in/out member 24 that moves in an arc shape together with the side plate 15 that moves diagonally up and down. The in/out member 24 selectively engages with one of the engaging portions 26 to stop the rotation of the inclined rods 16, 16 and maintain the height of the rice seed supply device 2.

Therefore, 27 is the paddy guide, and the paddy guide 2
7 is attached to the seed rice supply device 2 via a parallel link 28, and is used by being provided at a position below the horizontal axis feed-out roll 6 when the seed rice supply device 2 is switched to the upper position for row sowing. Moreover, although the paddy guide 27 has split drop ports 29 in the left and right direction, a plurality of guides having 18 to 20 split drop ports 29 are separately prepared and used interchangeably.

The parallel link 28 attaches both ends of the left and right shafts 30 and 31 to a fixture 32. The fitting 32 is inserted into a mounting groove 33 formed in the support fitting 22 from above.

(effect) Next, we will discuss the effect.

Since the present invention has the above-mentioned configuration, the seed rice 10 is fed into the seed rice supply hopper 1, and the flowing grain plate 3 and the flowing grain plate 4
Adjust the adjustment plate at the lower end to the desired position, rotate the horizontal axis feeding roll 6 and the leveling and awning paddy removing brush 11, and transfer the seedling box using the seedling box transfer table 14, and then the horizontal axis will be fed out. The rice seeds 10 fitted into the horizontal grooves 7 of the rolls 6 are guided by the rice seed guide plate 12 and are sown on the surface of the bed soil in the seedling raising box.

In this case, the seed rice supply device 2 includes inclined rods 16, 1
6 is attached to the support member 20 attached to each frame 19 of the transfer table 14, and the seed rice supply device 2
An in/out member 24 is attached to the mounting bracket 23 on the side plate 15 side so as to be able to move in and out.
, and engages with the engaging portion 26 of the support member 20 to restrict the rotation of the inclined rods 16, 16. Therefore, the retractable member 24 is pulled inward against the spring 25 and engaged. By simply removing it from the joint 26, the inclined rod 16,
16 can be rotated. Inclined rod 16,1
6 rotates around the shafts 21, 21 like parallel links, so that the seed rice supply device 2 is moved diagonally up and down.

Therefore, the entire seed rice supply device 2 is moved to the upper position T.
If the paddy guide 27 is attached below the horizontal axis feed-out roll 6, it can be used for row sowing, and when the entire seed supply device 2 is positioned at the lower position t, it can be used for scattering.

Then, when the in/out member 24 is pulled inward again and selectively engaged with one of the other engaging portions 26, the inclined rods 16, 16 are stopped with only a slight rotation. The height of the rice seed feeding device 2 can be finely adjusted from the upper position T to the lower position t depending on the seedling raising box used, and even seedling raising boxes of different heights can be used.

(Effect) None of the above-mentioned known examples are seeding devices that can be used for both row seeding and sowing. A paddy guide is required when row-sowing to a seedling-growing box, but a paddy guide is not required when sowing to a seedling-growing box. When attaching a paddy guide to a seedling raising box for row sowing, it is necessary to raise the seed rice supply device high enough to attach the paddy guide. When sowing into a seedling-growing box, if the seed feeding device is set high as in the case of row sowing, the seed feeding device will be too high and the seedlings will be scattered outside the seedling-growing box.

However, the present invention is equipped with a seed supplying device 2 having a seed supply hopper 1 and a horizontal shaft delivery roll 6 for discharging the seeds in the hopper 1, and a transfer table 14 capable of horizontally transferring the seedling raising box in the front-rear direction. A support member 20 is fixed to the transfer table 14, and the lower ends of a pair of front and rear parallel link rods 16, 16 that rotate at an angle are fixed to the support member 20 by shafts 21, 21, and the parallel link rods 16, The upper end of 16 is axis 1
7 and 17, the supporting member 20 is provided with a plurality of engaging portions 26 centered around the shaft 21, and the seed rice supplying device 2 is provided with a shaft. This seeding device for seedling raising boxes is equipped with an engaging body 24 that selectively engages with an engaging part 26, and a paddy guide 27 with a split drop opening 29 is removably attached to the lower part of the horizontal axis feeding roll 6. Therefore, (a) a support member 20 is fixed to the transfer table 14, and the lower ends of a pair of front and rear parallel link rods 16, 16 that rotate at an angle are fixed to the support member 20 by shafts 21, 21; The upper ends of the parallel link rods 16, 16 are fixed to the lower edges of the rice seed supply device 2 by shafts 17, 17, and the support member 20 is formed with a plurality of engaging portions 26 centered around the shaft 21. However, by providing an engaging body 24 selectively engaged with the engaging portion 26 on the side of the rice seed supply device 2, the engaging portion 2
By simply selectively engaging the engaging body 24 with 6, the row sowing position and the sowing position can be easily switched.

(b) Since the paddy guide 27 having the split drop opening 29 is detachably provided at the lower position of the horizontal axis feed-out roll 6, switching between row sowing and sowing can be performed by attaching and detaching the paddy guide 27.
