Description

[Detailed description of the invention] (Industrial field of application) The present invention relates to a row-seeding device for seedling-raising boxes (prior art) A feed-out roll with horizontal grooves formed below a conventional seed supply hopper is provided to raise seedlings. It is known that row seeding can be sown in the left and right directions using a box for raising seedlings that is transported in the front and back directions using a box transfer table.

(Problems to be Solved by the Invention) The above-mentioned known rice seedlings are gradually being used less and less because they require a special rice transplanter to plant 10 rice seedlings because they are sown in rows in the left and right directions with respect to the direction of movement of the seedling box.

That is, using a feed roll with horizontal grooves, f
'f When seed rice is sown in a seedling box that is transferred back and forth by the seedling box transfer table, row sowing can only be done in the left and right direction.

However, even with a feeding a-ru having horizontal grooves, seedlings can be vertically sown in an orderly manner in the front-rear direction with respect to a seedling-growing box that is transported in the front-back direction by a seedling-growing box transfer table.

(Means for Solving the Problem) Therefore, the present invention allows the seedling growing box 25 to move in the front-rear direction below the horizontal axis feed-out roll 6 on which the horizontal line yI7 is formed in the generatrix direction, and A paddy guide η having divided drop openings n arranged side by side in the left and right direction is provided between the rice seedling box 6 and the seedling raising box, so that rows can be sown in the front and back direction using the horizontal axis feed roll 6 having horizontal grooves 7 formed therein. This is a row sowing device for seedling boxes.

(Embodiment) An embodiment of the present invention will be described with reference to the drawings. ① is a seed rice supply hopper, and at the bottom of the seed rice supply hopper 1, an inverted grain flow plate 2.3 is provided to form a funnel 4, One grain board 2
is short, and the other grain grain board 3 is formed long, so that the lower end 5 of the grain grain board 3 comes into contact with the outer circumferential surface of the horizontal axis edge roll 6.

The horizontal axis edge roll 6 is provided at a lower position of the short grain grain plate 2, and is formed to have a larger diameter than the normal horizontal axis feed roll 6.

Horizontal grooves 7 parallel to the generatrix direction are formed on the outer peripheral surface of the horizontal axis feed roll 6 at desired intervals over the entire circumference. Further, slits 8 are provided along the entire circumference at desired intervals in the left-right direction. The depth of the slits 8 is formed slightly deeper than the horizontal grooves 7, and a knife 9 is fitted into each slit 8.

Directly above the horizontal axis feed roll 6 is a rotating brush that rotates in the opposite direction! The 0-rotation brush 10 that provides 0 has the function of leveling the seed rice 11 and the function of removing the seed grains with awns.

An endless rubber film 13 is brought into contact with the side surface of the horizontal axis feeding roll 6. The rubber film 13 functions to guide the rice seed 11 fitted into the horizontal groove 7 from a lower position to a lower position. 1
4 is an upper guide roll, 15 is a lower guide roll, 16.1
Reference numeral 7 denotes a pressure roll, which is pressed against the horizontal shaft delivery roll 6 by a spring. Reference numeral 1B denotes a tension pulley provided in the middle of the upper part, and forms a downstream part 19 between the upper guide roll 14 and the tension pulley 18.

20 is a receiving box 20 for the awned rice seed retainer that flows down the flowing part 19
It is.

A paddy guide η that is moved up and down by a parallel link 21 is provided below the horizontal axis feed-out roll 6. The paddy guide 22 has 18 to 22 divided drop openings 23 in the left-right direction. Reference numeral 24 denotes a seedling raising box transfer table, and 25 denotes a seedling raising box (function).The function will be described next.

Load the seed rice 11 into the seed supply hopper l, adjust the adjustment plates at the lower ends of the grain flow plates 2 and 3 to the desired positions, and rotate the horizontal axis feed roll 6, rotating brush lO, and rubber membrane 13, respectively. When the seedling growing box δ is transferred by the seedling growing box transfer table 24, the seed rice 11 flowing down on the grain board 3 of the funnel 4 fits into the horizontal groove 7.

The seed rice fitted in the horizontal groove 7 rises in that state, and when it reaches the lower part of the rotating brush 10, the excess seed 11 is returned, and the seed rice with awn is caught by the tip of the rotating brush 1O and rises. Then, the flowing FrB 19 of the rubber membrane 13 flows down to the receiving box 2.
It is retrieved at 0.

The rice seeds U pass under the rotating brush 10, are guided to the lower blade without spilling by the rubber film 13, and flow into the rice guide n at the lowest point. This paddy guide n is 18 to 2 in the left and right direction.
Since two divided drop openings 23 are formed, the seedlings are divided into several parts and sown in the seedling raising box 25.

Therefore, since the seedling box δ is moving in the front-back direction,
It is sown in rows.

(The operation and effect will be demonstrated with a photo in place of the first drawing.) The seed rice 11 that does not come off the horizontal groove 7 and tries to rise as it is is removed by the knife 9.

(Effects) The conventional M1 paddy supply hopper was equipped with a feed roll with horizontal grooves formed below it, and it was possible to perform row sowing in the left and right directions for the seedling box, which was transferred backwards by the seedling box transfer table. It is publicly known.

The above-mentioned known method is sown in rows in the left and right directions with respect to the direction of movement of the seedling box, so rice cannot be planted without a special rice transplanter.
It is becoming less and less used.

That is, when seed rice is sown in a seedling box that is transferred back and forth by a seedling box transfer table using a feed roll having horizontal grooves, row sowing can only be performed in the left and right direction.

However, in the present invention, the seedling raising box 25 is moved in the front-rear direction below the horizontal shaft feeding roll 6 in which the horizontal grooves 7 are formed in the generatrix direction, and the seedling growing box 25 is arranged between the horizontal shaft feeding roll 6 and the seedling growing box 25. is a paddy guide η with split drop ports 23 arranged in parallel in the left and right direction.
Since this is a row sowing device for a seedling box, which is capable of performing row sowing in the front and back direction using the horizontal axis feed roll 6 with horizontal grooves 7 formed therein, the seed rice 11 is guided all the way to the bottom and reaches the lowest point. The rice flows into the paddy guide η, and the paddy guide 22 is formed with 18 to 22 split drop openings 23 in the left and right direction.The paddy is divided into several parts and can be sown in rows in the seedling box 25 as shown in the photo. .
