A supply port 6 is formed between the floor soil supply hopper 4 and the feeding belt 5, and a supply shutter 7 for adjusting a supply amount is provided in the supply port 6. The supply shutter 7 is mounted on a frame side plate 10 fixed to the transfer table 1 by a pivot shaft 9 having a square shaft portion 8, and is fixed to an operation shaft 11 provided in parallel with the pivot shaft 9 and the axis direction. The supply amount is adjusted by the opening / closing operation dial 12.

The operation shaft 11 is positioned on the front side in the moving direction of the feeding belt 5 from the angular shaft portion 8 in a side view and above the axial center of the angular shaft portion 8. A gear 13 having a large radius is fixed to the angular shaft portion 8 of the operation shaft 11. A gear 14 having a smaller radius than the gear 13 is engaged with the gear 13, and the gear 14 is fixed to the operation shaft 11.
The pivot shaft 9 is formed with an angular shaft portion 8 at an intermediate portion and round bar portions 15 on both sides of the angular shaft portion 8, and the angular shaft portion is formed on the left and right side plates 17 of the on-off valve 16 of the supply shutter 7. A square hole 18 larger than 8 is formed, and the square shaft portion 8 is loosely inserted into the square hole 18 and is rotated with respect to the square shaft portion 8 until there is no looseness in any one direction. 8, the gear 13 is formed with a square hole 19 having the same size as that of the square hole 18, and the square hole 19 of the gear 13 is inserted through the square shaft portion 8. After rotating relative to the angular shaft portion 8 until there is no looseness in the other direction, the rotating portion of the gear 13 is fixed to one of the left and right side plates 17 with screws 20.

FIG. 4 is an exploded perspective view of the supply shutter 7. The supply shutter 7 has left and right side plates 17 bent at substantially right angles on both sides of the on-off valve 16 formed in an arc shape when viewed from the side. The left right plate 17 is formed with a square hole 18 through which the angular shaft portion 8 of the pivot shaft 9 is inserted. The square hole 18 is punched to be larger than the diameter of the square shaft portion 8, and the square shaft portion 8 and the square hole 18 are fitted with a backlash but have a size relationship that does not rotate. Form and fit the square shaft.
Reference numeral 21 denotes an auxiliary plate, which is attached to one of the left and right side plates 17. Similarly to the side plate 17, the auxiliary plate 21 is formed with a square hole 22 that is punched out to be larger than the diameter of the square shaft portion 8, and the square hole 22 is fitted to the square shaft portion 8 with a backlash. Reference numeral 23 denotes a long hole formed in the auxiliary plate 21, and reference numeral 23 </ b> A denotes a screw screwed into the screw hole through the long hole 23.

Thus, the left and right side plates 17 and the auxiliary plate 21 are individually engaged with the angular shaft portion 8 of the pivot shaft 9 with a backlash, but the left and right side plates 17 and the auxiliary plate 21 are connected to the angular shaft portion 8. After twisting to the opposite side, the shafts 23A can be fixed to each other by screws 23A so that the shafts can be fitted with no looseness.
That is, first, the square hole 22 of the auxiliary plate 21 is inserted into the square shaft portion 8 of the pivot shaft 9, and one of the left and right round rod portions 15 of the pivot shaft 9 in this state is connected to one of the left and right side plates 17. Next, the other of the left and right round bar portions 15 of the pivot shaft 9 is inserted into the other corner hole 18 of the left and right side plates 17, and the corner shaft portion 8 of the pivot shaft 9 is inserted into the corners of the left and right side plates 17. The hole 18 is penetrated.
Next, the opening / closing valve 16 that is engaged with the angular shaft portion 8 with looseness is twisted in the left rotation direction, for example, about the axial center of the angular shaft portion 8 on either one of the left and right sides with respect to the angular shaft portion 8. In the right rotation direction, a gap (backlash) remains between the outer periphery of the square shaft portion 8 and the inner periphery of the square hole 18 of the side plate 17, but the left rotation direction between the pivot shaft 9 and the on-off valve 16. There should be no gaps left in the back.

Next, in this state, the auxiliary plate 21 is twisted in the clockwise direction with respect to the angular shaft portion 8, and a backlash remains in the counterclockwise direction. Make sure there is no backlash in the clockwise direction.
Thus, after the side plate 17 and the auxiliary plate 21 are in a state in which the back plate remains in only one direction with respect to the angular shaft portion 8, both are fixed with the screw 23A. Thereby, as a whole, the left and right side plates 17 and the auxiliary plate 21 can be fitted to the square shaft portion 8 without angular play.
Thereby, as a whole, the left and right side plates 17, the auxiliary plate 21, and the gear 13 can be fitted to the square shaft portion 8 without any backlash.
Therefore, the gear 13 also functions as a part of the strength member that enhances the assembly strength of the supply shutter 7. By providing the gear 13, the side plate 17 and the square shaft portion 8 can be fixed without generating a backlash between the pivot shaft 9 and the gear 13. It does not occur and can be omitted.

The left and right round bar portions 15 of the pivot shaft 9 are protruded outward from the through holes of the left and right frame side plates 10 and are rotatably mounted only. An operating shaft 11 is mounted on the frame side plate 10, a gear 14 is fixed to the operating shaft 11, and a gear 13 is engaged with the gear 14. The gear 13 is fixed to the pivot shaft 9. When an opening / closing operation dial 12 is fixed to either one of the left and right ends of the operation shaft 11 and the gear 14 is rotated by the opening / closing operation dial 12, the gear 13 rotates about the pivot shaft 9, and the gear 13 rotates to the pivot shaft 9. And the opening / closing amount of the on-off valve 16 is adjusted by the rotation of the pivot shaft 9.
Therefore, since the opening / closing operation dial 12 is provided so as to protrude laterally with respect to the side plate 17 of the seedling box soil supply device 1, between the supply hopper floor soil supply hopper 4 and the feeding belt 5 from the side. While looking at the supply port 6, the supply amount can be adjusted by opening and closing the supply shutter 7 for adjusting the supply amount.
A floor soil leveling device 25 is provided on the transfer platform 1 on the lower side in the transport direction of the floor soil supply device 3 (FIGS. 1 and 12). The floor soil leveling device 25 has a rotating brush 26, and the rotating brush 26 levels the floor soil supplied to the seedling container A while scraping a predetermined amount.

That is, depending on various conditions such as soil properties, supply amount, and scraping amount, the scraping accuracy and leveling accuracy may be improved by switching the rotary brush 26 between high and low. It is not a requirement of this application.
In the floor soil leveling device 25, a rotary brush 26 is rotatably attached to an upper side of the transfer table 1 by an arm 27, and a pair of left and right frame side plates 28 are provided at a predetermined interval on the transfer table 1 inside the front arm 27. The frame side plate 28 is provided with a height adjusting device 30 for moving the brush rotating shaft 29 of the rotating brush 26 up and down. The height adjusting device 30 is provided at both ends of the brush rotating shaft 29 of the rotating brush 26. A pair of traction support members 31 are attached to each other, each traction support member 31 is attached to an adjustment screw shaft 33 having a dial 32 so as to freely move up and down, and the left and right adjustment screw shafts 33 are connected by a connection shaft 34, and an upper portion of the frame side plate 28. And a plurality of switching engaging step portions 35 having different heights for engaging and supporting the connecting shaft 34 from above.
The rotating brush 26 has both ends of a brush rotating shaft 29 mounted on a pair of left and right front arms 27, and a base portion of the front arm 27 is rotatably attached to the transfer table 1 by a base rotating shaft 36.

The height adjustment device 30 of the rotary brush 26 is provided with left and right frame side plates 28 on the transfer table 1, and the frame side plate 28 is formed with an insertion hole 37 through which the brush rotation shaft 29 is inserted. The rotating brush 26 is allowed to move up and down according to the different seedling container A (FIG. 6).
Lower ends of the traction support members 31 are respectively attached to both ends of the brush rotation shaft 29 of the rotary brush 26 protruding laterally from the frame side plate 28, and the lower portions of the adjustment screw shafts 33 are screwed onto the upper portions of the traction support members 31. . When the adjustment screw shaft 33 is rotated, the traction support member 31 moves up and down with respect to the adjustment screw shaft 33.
The upper part of the adjusting screw shaft 33 is rotatably attached to the connecting shaft 34 in the left-right direction. When the dial 32 is lifted, the connecting shaft 34 moves upward. The traction support member 31 is provided with a spring 38 between the traction support member 31 and the fixed part such as the transfer table 1 and urges the traction support member 31 so as to always be pulled downward.

Thus, on the upper edge of the frame side plate 28, a switching engagement step portion 35 for engaging the connecting shaft 34 is arranged on a plurality of arcs, and any one of the plurality of switching engagement step portions 35 is provided. Is selectively engaged.
In this case, among the switching engagement step portions 35, the center switching engagement step portion 35a in which the connecting shaft 34 is positioned vertically above the brush rotation shaft 29 is used as a reference step portion, and in this state, the left and right adjustment screws The shaft 33 is rotated so that the lower end of the rotary brush 26 is brought into contact with the upper surface of the front wall 39 of the seedling raising container A, the scraping amount is set to “zero”, and the switching is sequentially performed in the lower order on the front and rear sides of the center switching engagement step 35a. An engaging step 35 is formed, and the connecting shaft 34 is engaged with the switching engaging step 35 so that the lower end of the rotary brush 26 is positioned below the upper surface of the front wall 39 of the seedling raising container A, Scrape a predetermined amount.
That is, in the engaged state with the center switching engagement step 35a, the lower end of the rotating brush 26 is brought into contact with the upper surface of the front wall 39 of the seedling container A to set the scraping amount to an initial state of “zero”, and other switching When selectively engaged with the engagement step 35, the lower end of the rotary brush 26 is lowered by 7 to 15 mm from the upper surface of the front wall 39 of the seedling raising container A, and a predetermined amount of floor soil can be scraped off. .

In this case, the brush rotation shaft 29 is on an arc line on which the rear arm 16 rotates about the base rotation axis 36 and on the arc line on which the traction support member 31 rotates about the connecting shaft 34. Therefore, when adjusting the height, the vertical amount of the brush rotating shaft 29 does not match the step amount of each switching engagement step portion 35.
Therefore, among the switching engagement step portions 35, the center switching engagement step portion 35a in which the brush rotating shaft 29 and the connecting shaft 34 are positioned vertically is used as a reference step portion, and in this state, the left and right adjustment screws The shaft 33 is rotated so that the lower end of the rotating brush 26 is brought into contact with the upper surface of the front wall 39 of the seedling raising container A, and the scraping amount is adjusted to be “zero”, before and after the center switching engagement step 35a. On the side, a switching engagement step 35 which is lower than the center switching engagement step 35a is formed in order, and selectively engaged with the other switching engagement step 35.
Therefore, the lower end of the rotary brush 26 is positioned below the upper surface of the front wall 39 of the seedling raising container A by selectively engaging with the switching engagement step 35 lower than the “zero setting” center switching engagement step 35a. And scrape a predetermined amount of floor soil.

In this case, since the switching engagement step portion 35 of the embodiment is formed so as to be alternately lowered on the front and rear sides with respect to the center switching engagement step portion 35a, the base rotation shaft 36 and the connecting shaft 34 are formed. The change in the amount of movement of the brush rotating shaft 29 that moves in a circular arc around these two points is minimized to improve the accuracy of setting the scraping amount. That is, as an example, when the four-step switching engagement step portion 35 of 7 mm, 10 mm, 12 mm, and 15 mm is formed, 15 mm (fourth switching engagement step portion 35 e), 12 mm (fourth switching engagement step portion 35 e) from the rear side view. Three switching engagement step portions 35d), 0 mm (center switching engagement step portion 35a), 7 mm (first switching engagement step portion 35b), and 10 mm (second switching engagement step portion 35c). Therefore, the shift between the switching engagement step portions 35 is also reduced.
Side view, 15 mm (fourth switching engagement step 35 e), 10 mm (second switching engagement step 35 d), 0 mm (center switching engagement step 35 a), 7 mm (first switching engagement) You may form in order of the step part 35b) and 12 mm (3rd switching engagement step part 35c).
As will be described later, the rotary brush 26 is driven to rotate by transmitting the rotation from the transfer roll 2 of the transfer table 1.

Since the traction support member 31 is always pulled downward by the spring 38, when the adjustment screw shaft 33 is rotated to lower the traction support member 31, the traction support member 31 is lowered by the elasticity of the spring 38. When the adjusting screw shaft 33 is rotated in the reverse direction, the pulling support member 31 is moved up against the elasticity of the spring 38.
In this case, since the lower part of the adjustment screw shaft 33 is screwed onto the upper part of the pulling support member 31, when the dial 32 is rotated, the pulling support member 31 moves up and down with respect to the adjustment screw shaft 33.
Further, when the dial 32 is lifted, the connecting shaft 34 is moved upward, and the connecting shaft 34 is lifted not only by the connecting shaft 34 but also by the left and right dials 32 and is engaged with other switching engagement step portions 35. The scraping amount of the front-rear rotating brush 26 can be changed.
Further, if the insertion hole 37 through which the brush rotation shaft 29 is provided in the frame side plate 28 is formed in an arc shape with the base rotation shaft 36 as the center, it is preferable that the brush rotation shaft 29 is smoothly moved up and down.

Thus, the irrigation device 45 is provided on the lower side of the rotating brush 26. The irrigation apparatus 45 forms a nozzle hole 47 at a predetermined interval in a pair of front and rear irrigation horizontal cylinder portions 46, one end of the irrigation horizontal cylinder portion 46 is closed by a plug 48, and the other end is attached to and detached from the connecting pipe 49 and rotated. Install freely. The connecting pipe 49 connects the rising cylindrical portion 50 to the front and rear center positions, and one end of the upper horizontal cylindrical portion 51 is connected to the rising cylindrical portion 50. The upper horizontal cylinder portion 51 is provided with a water meter (pressure gauge) 52, an adjustment valve 53, an opening / closing valve 54, a relief valve 55, and a hose connection portion 56.

In the irrigation device 45, a pair of irrigation horizontal cylinder portions 46, a connecting pipe 49, a rising cylinder portion 50, and an upper horizontal cylinder portion 51 constitute an irrigation pipe 57, and the irrigation pipe 57 is attached to an irrigation frame 58 provided on the transfer table 1. It is configured to be detachable. The irrigation frame 58 is provided with a central support portion 60 that supports the upper horizontal cylinder portion 51 of the irrigation pipe 57 at an intermediate position on the upper and lower sides of the central frame 59 formed by a pair of left and right plate members. Arm portions 61 are provided on both front and rear sides of the central frame 59, and the irrigation tube support portions 62 that support the irrigation horizontal tube portion 46 of the irrigation pipe 57 are provided on the arm portion 61.

In the irrigation pipe 57, each part of the irrigation pipe 57 is placed on the central support part 60 and the irrigation cylinder support part 62 of the irrigation frame 58, a cover 65 is placed above the irrigation pipe 57, and the cover 65 is placed on the irrigation frame. It is fixed to 58 with a fastening tool 66.
Therefore, since the irrigation pipe 57 is simply placed on the irrigation frame 58 and pressed by the cover 65, the irrigation pipe 57 is sandwiched up and down by the irrigation frame 58 and the cover 65, and can be attached and detached while having a simple support structure. It becomes easy.
Therefore, the cover 65 only needs to have a shape that can hold the irrigation pipe 57 from above, and the upper top plate 67 that contacts the upper horizontal tube portion 51 and the irrigation horizontal tube portion 46 that is connected to the upper top plate 67. What is necessary is just to comprise having the nozzle contact part 68 contact | abutted to the upper surface of this, and the opening window part 69 which avoids the said water meter water meter 52 grade | etc.,. The opening window 69 is formed in such a size that it can be removed so as to be pulled upward while avoiding the water meter 52. Reference numeral 70 denotes a nut to which a fastener 66 provided on the irrigation frame 58 is screwed.
The irrigation device 45 irrigates the floor soil of the seedling container A. By rotating the irrigation horizontal tube portion 46 with respect to the connecting pipe 49, the nozzle hole 47 is inclined to supply water for irrigation.

(Operation of Example)
When the seedling raising container A is supplied to the starting end portion of the transfer stand 1, the seedling raising container A reaches below the floor soil supply device 3 by the transfer roll 2.
In the floor soil supply device 3, since the floor soil feed belt 5 rotates, the floor soil in the floor soil supply hopper 4 is fed from the supply port 6 between the floor soil supply hopper 4 and the feed belt 5. The floor soil fed by the belt 5 and fed from the supply port 6 is supplied to the seedling raising container A passing below.
Since a supply shutter 7 for adjusting the supply amount is provided at the supply port 6 of the floor soil supply device 3, when the gear 14 is rotated by the opening / closing operation dial 12 of the operation shaft 11, the gear 13 is centered on the pivot shaft 9. The gear 13 rotates the pivot shaft 9, and the opening / closing amount of the on-off valve 16 is adjusted by the rotation of the pivot shaft 9.

In this case, since the supply amount is adjusted by the opening / closing operation dial 12 fixed to the operation shaft 11 provided in parallel with the pivot shaft 9 and the axis direction, the operator is positioned on the side of the floor soil supply device 3 and is placed on the floor. The amount of supply can be adjusted while looking at the supply port 6 of the soil supply hopper 4 to improve operability.
The presence of the operation shaft 11 provided with the opening / closing operation dial 12 does not affect the adjustment of the supply amount while looking at the supply port 6, and does not deteriorate the operability of the adjustment work.
The pivot shaft 9 is formed with an angular shaft portion 8 at an intermediate portion and round bar portions 15 on both sides of the angular shaft portion 8, and the angular shaft portion is formed on the left and right side plates 17 of the on-off valve 16 of the supply shutter 7. A square hole 18 larger than 8 is formed, and the square shaft portion 8 is loosely inserted into the square hole 18 and is rotated with respect to the square shaft portion 8 until there is no looseness in any one direction. 8, the gear 13 is formed with a square hole 19 having the same size as that of the square hole 18, and the square hole 19 of the gear 13 is inserted through the square shaft portion 8. Since the rotating portion of the gear 13 is fixed to either one of the left and right side plates 17 with a screw 20 after being rotated with respect to the angular shaft portion 8 until there is no looseness in the other direction, highly accurate press working Even if it is formed without performing the above, the on-off valve 16 can be fixed to the square shaft portion 8 without looseness. Although the operation of the opening / closing operation dial 12 is transmitted to the supply shutter 7 by meshing the pair of gears 14 and 13, the lower edge of the supply shutter 7 can be moved up and down substantially horizontally, and the supply amount is subtle. Can be easily adjusted.

The seedling container A that has been supplied with the floor soil by the floor soil supply device 3 is located below the floor soil leveling device 25 or is supplied to the seedling container A by the rotating brush 26 of the floor soil leveling device 25. Leveling while scraping a predetermined amount.
That is, if the top surface of the floor soil in the seedling raising container A is not leveled, the seeds sowed will be offset, so the top surface of the floor soil in the seedling growing container A is leveled. In order to level the upper surface of the floor soil in the seedling raising container A, the floor soil supply device 3 supplies extra floor soil in advance and removes the excess floor soil.
The floor soil leveling device 25 has a rotary brush 26 mounted on an upper side of a transfer table 1 by an arm 27 so as to be rotatable, and a pair of left and right frame side plates 28 are provided at a predetermined interval on the transfer table 1 inside the front arm 27. The frame side plate 28 is provided with a height adjusting device 30 for moving the brush rotating shaft 29 of the rotating brush 26 up and down. The height adjusting device 30 is paired at both ends of the brush rotating shaft 29 of the rotating brush 26. Each of the traction support members 31 is attached to an adjustment screw shaft 33 having a dial 32, and the left and right adjustment screw shafts 33 are connected by a connection shaft 34, and are attached to the upper portion of the frame side plate 28. Since a plurality of switching engaging step portions 35 having different heights for supporting the connecting shaft 34 by engaging from above are provided in the front-rear direction, first, the adjusting screw shaft 33 is rotated to pull it. Is moved up and down the support member 31 relative to the adjustment screw shaft 33, matching the lower end of the rotary brush 26 to the height of the front wall of the nursery container A.

Next, when the connecting shaft 34 is selectively engaged with any one of the plurality of switching engaging step portions 35, the lower end of the rotating brush 26 is positioned at a predetermined scraping height.
In this state, the seedling container A that has received extra supply of floor soil is located below the floor soil leveling apparatus 25, or the upper surface of the floor soil in the seedling container A is leveled by the rotating brush 26 of the floor soil leveling apparatus 25. Scrape off excess floor soil while flattening.
In this case, in the engaged state with the center switching engagement step portion 35a, the adjusting screw shaft 33 is rotated so that the lower end of the rotating brush 26 is brought into contact with the upper surface of the front wall 39 of the seedling raising container A to reduce the scraping amount. Since the initial state of “zero” is sufficient, as long as the initial setting is made, the change of the scraping amount from the upper surface of the front wall 39 of the seedling raising container A can be changed and switched only by selectively engaging with the other engaging step 35 for switching. This makes it easier to adjust the scraping amount.
The seedling raising container A in which the inner floor soil is leveled by the rotating brush 26 of the floor soil leveling device 25 reaches the lower side of the irrigation device 45 and irrigates water from the nozzle hole 47 of the irrigation horizontal tube portion 46 of the irrigation device 45. receive.

In the irrigation apparatus 45, one end of the irrigation horizontal cylinder portion 46 is closed by a plug 48, and the other end is detachably attached to the connection pipe 49, so that the irrigation horizontal cylinder portion 46 is rotated with respect to the connection pipe 49. Then, the direction of the nozzle hole 47 can be changed, and optimal irrigation can be performed according to various conditions such as soil properties and supply amount.
That is, simply increasing the irrigation amount increases the flooding pressure from the nozzle hole 47, which may disturb the top surface of the soil, but such a problem can be avoided by changing the direction of the nozzle hole 47. .
In addition, the irrigation device 45 irrigates the floor soil of the seedling container A. When the nozzle hole 47 is inclined by rotating the irrigation horizontal tube portion 46 with respect to the connecting pipe 49, water for irrigation is supplied. An action of leveling the floor soil K at the corner of the rear wall of the rear wall of the seedling raising container A by spraying backward can also be expected.
The irrigation device 45 connects one end of the upper horizontal cylinder part 51 to the rising cylinder part 50 of the connecting pipe 49, and the upper horizontal cylinder part 51 includes a water meter (pressure gauge) 52, a regulating valve 53, an open / close valve 54, and a relief. Since the valve 55 and the hose connection part 56 are provided, the amount of irrigation is adjusted by the adjustment valve 53, and once adjusted, the irrigation can be stopped by stopping the irrigation by the opening / closing valve 54. By simply opening the opening / closing valve 54, it is unnecessary to adjust the amount of irrigation, and the operability of irrigation work in general can be improved.

Further, the water meter 52 measures the water pressure in the upper horizontal cylinder portion 51 and sets the irrigation amount from the nozzle hole 47 in advance by this water pressure, so the water amount formed by the instrument that measures the water pressure in the upper horizontal cylinder portion 51. By using the total 52, the irrigation amount can be adjusted, and an inexpensive irrigation apparatus 45 can be provided.
The irrigation device 45 places each part of the irrigation pipe 57 on the central support part 60 and the irrigation cylinder support part 62 of the irrigation frame 58, places a cover 65 above the irrigation pipe 57, and attaches the cover 65 to the irrigation frame. Since the irrigation pipe 57 is simply mounted on the irrigation frame 58 and pressed by the cover 65, the irrigation pipe 57 is clamped up and down by the irrigation frame 58 and the cover 65. Therefore, it is easy to attach and detach while having a simple support structure.
The seedling raising container A that has received irrigation on the inner floor soil reaches the lower side of the seed supply device 75 and receives the supply of seeds from the seed supply device 75.

  The seed supply device 75 has a large diameter of 150 millimeters or more and a seed supply hopper on the rear upper portion of the horizontal axis feeding roll 84 provided with a feeding recess 85 in the busbar direction and a slit 86 intersecting the feeding recess 85 on the outer peripheral surface. 78, and a seed reservoir 96 is formed by bringing the vicinity of the front end of the front guide plate 80 of the seed supply hopper 78 close to the outer peripheral surface of the horizontal axis feeding roll 84. A rotating seed return brush 95 is provided for sweeping excess seed that does not fit into the feeding recess 85 and co-rotates with the horizontal axis feeding roll 84 to the seed reservoir 96, and is provided on the rear side surface of the horizontal axis feeding roll 84. Since the seed guiding device 97 that guides the seed fitted in the feeding recess 85 from the upper position to the lower position is provided, the seed in the seed supply hopper 78 is transferred to the seed reservoir 9. Then, the seed fitted into the feeding recess 85 of the horizontal axis feeding roll 84 is rotated together with the horizontal axis feeding roll 84 and passes under the rotating seed return brush 95, so that the rotating seed return brush 95 is rotated. The seeds that have passed below are guided from the upper position to the lower position by the seed guiding device 97, reach the lower position of the horizontal axis feeding roll 84, fall from the feeding recess 85 to the seedling raising container A, and are sown.

Since the horizontal axis feeding roll 84 has a large diameter of 150 mm or more, the large diameter horizontal axis feeding roll 84 increases the seeding amount even at the same number of rotations as compared with the small diameter horizontal axis feeding roll. Work efficiency can be improved.
That is, the moving speed of the feeding recess 85 of the large-diameter horizontal axis feeding roll 84 becomes slower than the moving speed of the feeding recess of the small-diameter horizontal axis feeding roll even at the same rotational speed. Since the seed can be fitted into the feeding recess 85 even if the speed is increased, the number of rotations of the horizontal shaft feeding roll 84 can be increased without lowering the certainty of fitting the seed, and the work efficiency is improved. Can be made.
Since the rotating seed return brush 95 is provided above the horizontal axis feeding roll 84, excess seed that rotates together with the horizontal axis feeding roll 84 without being fitted into the feeding recess 85 is swept back to the seed reservoir 96. Can do.

Therefore, the seeds that are not fitted in the feeding recess 85 do not pass below the rotating seed return brush 95 and are swept back to the seed reservoir 96, so that only the seeds fitted in the feeding recess 85 fall into the seedling raising container A. And sowing amount can be set accurately.
In addition, since the seeds not fitted in the feeding recess 85 are swept back to the seed reservoir 96 without passing below the rotating seed return brush 95, the excessive seeds swept back to the seed reservoir 96 are also seeded. The portion 96 is fitted into the feeding recess 85 and co-rotated with the horizontal shaft feeding roll 84 so that seeds are not wasted.
Since the seed guiding device 97 is provided on the rear side surface of the horizontal axis feeding roll 84, the seed fitted in the feeding recess 85 extends from a position below the rotating seed return brush 95 to a position below the horizontal axis feeding roll 84. It is guided by the seed guiding device 97 without being damaged.
Since the seed guiding device 97 has an elastic member (sponge) 100 formed to have substantially the same thickness from the inside of a metal mounting plate 98 formed in an arc shape, the elastic member 100 is attached to the horizontal axis feeding roll 84. The seed that is elastically adhered to the outer peripheral surface and prevents the seed fitted in the feeding recess 85 from coming off from the feeding recess 85 is rotated together with the horizontal axis feeding roll 84 while being fitted.

Since the guide film 101 having a smooth surface formed of synthetic resin is attached to the surface of the elastic member 100, the seed is prevented from being caught by the elastic member 100 and is smoothly guided.
In this case, since the upper end portion of the guide film 101 is bent rearward and fixed to the upper end edge of the mounting plate 98, the seed fitted in the feeding recess 85 passing under the rotating seed return brush 95 is smooth. And is guided under the transfer roll 2.
Slits 86 are provided on the outer peripheral surface of the horizontal shaft feed roll 84 in the entire circumference around the generatrix (left and right) at intervals shorter than the lateral width of one seed, and each slit 86 has a scraping knife 87. Since most of the seeds fitted into the feeding recess 85 are naturally fallen by their own weight at the seed drop position almost directly below the horizontal axis feeding roll 84, they are sown in the seedling raising container A. Among the seeds fitted into the seed 85, the seeds that do not fall naturally by their own weight at the seed drop position almost directly below the horizontal axis feeding roll 84 hit the scraping knife 87 and are forcibly dropped.

For this reason, there is no seed in the feeding recess 85 of the horizontal axis feeding roll 84 after the scraping knife 87, and seeds are newly fitted in the seed reservoir 96, thereby preventing the occurrence of a missing line.
In addition, since the depth of the slit 86 of the horizontal axis feeding roll 84 is substantially the same as or slightly deeper than that of the feeding recess 85, the scraping knife 87 is a seed that does not fall naturally in the depth direction of the fitting recess feeding recess 85. Make sure to abut and force drop.
In addition, since the slits 86 are formed with an interval shorter than the lateral width of one seed, the scraping knife 87 always comes into contact with the seed that does not fall naturally in the width direction of the fitting recess feeding recess 85. Force drop.
The scraping knife 87 is formed of a thin plate member that can be fitted into the slit 86, and the cylindrical member 89 is attached to the mounting hole at the base of the scraping knife 87, and each cylindrical member 89 is attached to the mounting shaft mounting shaft 90. When the cylindrical member 89 is inserted into the mounting shaft 90, the cylindrical members 89 come into contact with each other, and the scraping knives 87 are arranged at substantially the same interval in the axial direction of the mounting shaft 90 by the cylindrical member 89. Since the dispensing knives 87 are movable in the axial direction of the mounting shaft 90, each scraping knife 87 is fitted in the slit 86 while moving in the axial direction of the mounting shaft 90.

That is, if the scraping knife 87 is fixed to the mounting shaft 90, the spacing of the scraping knife 87 and the spacing of the slit 86 do not exactly match due to manufacturing errors or the like. 87 does not fit into the slit 86, but each scraping knife 87 moves in the axial direction of the mounting shaft 90, so that manufacturing errors are absorbed and the scraping knife 87 fits into the slit 86.
Further, since the cylindrical members 89 are formed to have a length shorter than the interval between the slits 86, when the cylindrical members 89 are inserted through the attachment shafts 90, the cylindrical members 89 come into contact with each other, and the scraping knife 87 is moved by the cylindrical member 89. Since the mounting shafts 90 are arranged at substantially the same interval in the axial direction, it is not necessary to align the scraping knives 87 with the slits 86 one by one, and the assembly is facilitated.
Further, the tip of the scraping knife 87 is positioned on the lower side of the rotation direction than the lower end edge 102 of the guide film 101, but the tip of the scraping knife 87 is close to the lower end edge 102 of the guide film 101. The seed fitted in the feeding recess 85 of the horizontal axis feeding roll 84 at the lower end edge 102 of the guide film 101 can be dropped.

Since the scraper 115 is provided in the upper position of the transfer stand 1 after the soil covering supply operation of the soil covering supply device 110 is completed, the scraper 115 removes the soil covering dropped on the front and rear walls and the left and right side walls of the seedling container A. To do.
The scraper 115 is formed by an upper plate 116 and a lower plate 117 that are made of a metal plate and are long in the left-right direction. A left-right mounting shaft 119 is fixed to the upper end of the upper plate 116, and both ends of the mounting shaft 119 are at a transfer table. Since the pair of left and right support members 120 attached to 1 are pivotally attached to the support member 120, the heavy scraper 115 reliably removes the covering soil dropped on the front and rear walls of the seedling container A and the upper surfaces of the left and right side walls. .

That is, since the covering soil falls on the upper surface of the seedling container A irrigated by the irrigation device 45, it absorbs the irrigation water and becomes heavier, and escapes when pressure is applied by an elastic member such as rubber or a brush. Although the removal cannot be performed sufficiently, the scraper 115 is made of a metal plate having a predetermined thickness, so that the cover is removed well because the scraper 115 is heavy and the scraper 115 is made of a metal plate and is hard. Can do.

The plate 117 is configured so that the upper surface of the left and right side walls of the seedling container A is simultaneously rubbed and cleaned, and the abutting portion 121 comes into impact contact with the support member 120 when rotated downward. -When the abutment part 121 abuts on the support member 120 and the downward rotation is stopped and the front end of the seedling raising container A comes into contact with the rear surface of the scraper 115, the parr 115 When the front end of the seedling raising container A passes under the lower end of the lower plate 117, the upper rotation of the scraper 115 stops and the lower plate is stopped. The bottom edge of 117 closely contacts the edge of the seedling container A to remove the covering soil. When the rear wall of the seedling raising container A passes below the lower plate 117, the scraper 115 is pivoted downward, and the contact portion 121 of the scraper 115 abuts on the support member 120 in an impact manner. The lowering rotation of the pad 115 is stopped and the soil adhering to the scraper 115 is dropped.

The scraper 115 is divided into an upper plate 116, a lower plate 117, and a sliding contact plate 118. An attachment hole 121A is formed in one of the lower plate 117 and the sliding contact plate 118, and a bolt is formed in the mounting hole 121A.
