Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a row seeding device for seedling boxes.

(Prior art) In the conventionally known Japanese Utility Model Publication No. 53-23629, a round hole-shaped seed feeding recess is formed on the circumferential surface at a position above a seedling box transfer table that transfers the seedling box in the front-rear direction. A horizontal shaft feed-out roll whose center is in the left-right direction, a derivative that guides the seed rice to a position below the feed-out roll provided at a predetermined interval on the rotating downward side side of the horizontal shaft feed-out roll, A seeding device consisting of a paddy guide with a plurality of divided drop openings arranged in parallel on the left and right sides of a fixed position is provided at a lower position, and the recess for seed delivery is a round recess into which one or two seeds fit, and the paddy The guide is described as having a structure in which the width of the split drop opening matches the interval between the round recesses.

Furthermore, in the conventionally known Japanese Utility Model Publication No. 53-23627, a transverse groove-like recessed portion for dispensing seeds that is long in the generatrix direction is formed on the circumferential surface at a position above the seedling box transfer table that transfers the seedling box in the front-rear direction. A horizontal shaft feed-out roll whose shaft center is in the left-right direction, an opening on the rotating downward side of the horizontal shaft feed-out roll that receives the seed rice that fits into the horizontal groove-like recess, and a guide groove that guides the seed rice that has flowed into the opening. A row-seeding device for a seedling raising box is provided, which comprises a paddy guide having guiding parts arranged side by side on the left and right, the paddy guide inclining the guiding part so as to be located at the rear as it reaches the seedling raising box, and having an inclination angle of There is described a device for both sowing and row sowing for a seedling raising box which is configured to be freely adjustable, and in which the guide portion has no guide groove and is detachable and replaceable.

(Problem that the invention aims to solve) At the request of farmers, two types of seedlings are grown: small seedlings and large seedlings. As an example, 18 horizontal and 20 seedlings are grown in a seedling box of the same size.

In this case, in the method described in Japanese Utility Model Publication No. 53-23629, both the horizontal shaft feed-out roll and the paddy guide were replaced. Since this is difficult, and the production of the horizontal shaft delivery roll itself is also difficult in the known products, we started our research to find out whether it was possible to manufacture a product that would not require replacing only the horizontal shaft delivery roll.

Research has shown that the seed dispensing recess formed on the circumferential surface of the horizontal shaft dispensing roll can be used as a horizontal groove-like recess long in the generatrix direction, as long as the number of split drop openings on the paddy guide is varied. This has been confirmed.

In addition, in the method described in Japanese Utility Model Publication No. 53-23627, the paddy guide is replaced in order to switch between row sowing and scattering, and sowing cannot be performed by changing the number of rows.

(Means for Solving the Problems) Therefore, the present invention has a transverse groove-like recess 7 for dispensing seeds that is long in the generatrix direction on the circumferential surface at a position above the seedling box transfer table 24 that transfers the seedling box 25 in the front-rear direction. A horizontal-axis feed-out roll 6 whose axis is oriented in the left-right direction, and seed rice that is in sliding contact with the peripheral surface of the side surface on the downward rotation side of the horizontal-axis feed-out roll 6 and fitted into the horizontal groove-shaped recess 7 are transferred to the horizontal axis feed-out roll. 6, and a paddy guide 22, which is attached to the lower position of the horizontal axis feed-out roll 6 by a parallel link 21 so as to be movable up and down, and has a plurality of divided drop ports 23 arranged in parallel on the left and right sides. A row sowing device for a seedling raising box is provided, and the paddy guide 22 is configured so that the seed rice falls in the vertical direction through the divided drop openings 23, and is detachable and replaceable with a plurality of types having different numbers of divided drop openings 23. This is a row sowing device for seedling boxes.

(Example) An example of the present invention will be described with reference to the drawings.

is formed long, and the lower end 5 of the grain flow plate 3 comes into contact with the outer circumferential surface of the horizontal axis feed roll 6.

The horizontal axis feeding roll 6 is provided below the short grain grain plate 2, and is formed to have a larger diameter than the normal horizontal axis feeding roll 6.

Horizontal groove-like recesses 7 parallel to the generatrix direction are formed on the outer peripheral surface of the horizontal shaft feed roll 6 at desired intervals in the circumferential direction. Further, slits 8 are provided around the entire circumference at desired intervals in the left and right direction. The depth of the slits 8 is formed to be slightly deeper than the horizontal groove-like recess 7, and a knife 9 is fitted into each slit 8.

A rotating brush 10 that rotates in the opposite direction is provided at a position directly above the horizontal axis feeding roll 6. The rotating brush 10 has the function of leveling the seed rice 11 and taking out the seed rice 12 with awns.

A guide member 13 made of an endless rubber film is brought into contact with the side surface of the horizontal shaft feed roll 6. Derivative 13
is expected to have the effect of guiding the seed rice 11 fitted into the horizontal groove-shaped recess 7 from the upper position to the lower position. 14 is an upper guide roll, 15 is a lower guide roll, 16,
Reference numeral 17 denotes a pressure roll, which is pressed against the horizontal axis feeding roll 6 by a spring. Reference numeral 18 denotes a tension pulley provided in the middle of the upper portion, and forms a downstream portion 19 between the upper guide roll 14 and the tension pulley 18.

20 is rice seed with awns 12 flowing down the flowing part 19 and falling
It is a receiving box.

Parallel link 2 is located below the horizontal axis feeding roll 6.
1 is provided with a paddy guide 22 that moves up and down. The paddy guide 22 has split drop ports 23 in the left and right direction, and a plurality of paddy guides 22 having 18 to 20 split drop ports 23 are prepared and are detachably attached to the parallel link 21.

Reference numeral 24 denotes a seedling-raising box transfer table, and 25 denotes a seedling-raising box.

(effect) Next, we will discuss the effect.

Load the seed rice 11 into the seed supply hopper 1, adjust the adjustment plates at the lower ends of the grain flow plates 2 and 3 to desired positions, and rotate the horizontal axis feed roll 6, rotary brush 10, and induction body 13, respectively. When the seedling growing box 25 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-shaped recess 7.

The seed rice that has fitted into the horizontal groove-shaped recess 7 rises in that state, and when it reaches the lower part of the rotating brush 10, the excess seed rice 11 is returned, and the seed rice with awns 12 is caught by the tip of the rotating brush 10 and rises. and derivative 13
It flows down the downstream part 19 and is taken out into the receiving box 20.

The rice seeds 11 pass below the rotating brush 10, are guided downward by the guide 13 without spilling, and flow into the rice guide 22 at the lowest point.

There are 18 and 20 paddy guides 22 in the left and right direction, but if the paddy guide 22 is formed with 18 split drop openings 23, it will be divided into 18 parts in the left and right direction. 18 rows are sown.

Therefore, since the seedling growing box 25 is moving in the front-back direction, row sowing is performed.

In this case, since the paddy guide 22 having 20 divided drop ports 23 is separately prepared, by replacing it and attaching it to the parallel link 21, it is possible to sow 20 rows.

Note that the seed rice 11 that does not come out of the horizontal groove-shaped recess 7 and tries to rise as it is is scraped out by the knife 9.

(Effects) The conventionally known method described in Japanese Utility Model Publication No. 53-23629 could not cope with changes in rows unless both the horizontal axis feed-out roll and the paddy guide were replaced.

Furthermore, in the conventional method described in Japanese Utility Model Publication No. 53-23627, the paddy guide is replaced in order to switch between row sowing and scattering, and the number of rows cannot be changed to sow.

However, in the present invention, a transverse groove-like recess 7 for dispensing seeds, which is long in the generatrix direction, is formed on the circumferential surface at a position above the seedling box transfer table 24 that transfers the seedling box 25 in the front-rear direction, and the axis is lateral in the left-right direction. A guide member 13 that slides on the side circumferential surface of the axially dispensing roll 6 and the rotating downward side of the lateral dispensing roll 6 and guides the seed rice fitted in the horizontal groove-like recess 7 to a position below the horizontal dispensing roll 6. and a parallel link 21 at a lower position of the horizontal shaft feeding roll 6.
A row sowing device for a seedling box is provided, which comprises a paddy guide 22 that is vertically movable and has a plurality of split drop ports 23 arranged in parallel on the left and right sides. This row-seeding device for a seedling-raising box is configured so that the paddy grains fall down, and has a plurality of types with different numbers of split drop openings 23 and is detachable and replaceable. It can respond to changes, saving both cost and effort.

A guide member 1 that slides on the side circumferential surface of the horizontal shaft feed-out roll 6 on the downward rotation side and guides the seed rice fitted in the horizontal groove-shaped recess 7 to a position below the horizontal shaft feed-out roll 6.
3, the seed rice is evenly supplied to the left and right sides of the upper part of the rice guide 22, and accurate row sowing can be expected.

Since the paddy guide 22 is attached to a position below the horizontal axis feed-out roll 6 by a parallel link 21 so as to be vertically movable, row sowing is possible even if the heights of the seedling boxes 25 to be transferred are different.

Further, since the paddy guide 22 can be positioned close to the top surface of the seedling growing box 25, row sowing can be performed accurately.

Since the divided drop openings 23 of the paddy guide 22 are formed in the vertical direction, the seed paddy falls smoothly and reliably and is sown in rows.

Further, the horizontal groove-shaped recess is easier to manufacture than the conventional round-hole recess.

This effect is achieved.
