It is configured to be movable relative to the horizontal axis feeding roll 9 so that the position of the rotary leveling brush 13 can be adjusted.

[0015]

[Operation] Next, the operation will be described. At the time of sowing, the seed feeding device 1 is slightly lifted by the operating lever 33, the engagement shaft 47 at the tip of the arm 46 of the height adjusting mechanism 45 is removed from the row-growing engagement groove group 49, and the seed feeding device 1's own weight is applied. The front connecting rod 20 and the rear connecting rod 21 are lowered, and the front connecting rod 20 and the rear connecting rod 21 move the left and right front rotating arms 18, 18 and the rear rotating arms 19, 19 together to form the horizontal shaft 26. The seed supply device 1 is vertically moved to a lower height for sowing with respect to the transfer table 15 by rotating downward about the horizontal shaft 27, and the engaging shaft 47 of the height adjusting mechanism 45 is sowed for engagement. It is engaged in the groove 48 and held at this position. Then, the strip roll 31 and the compression roll 32 are moved upward so that they do not come into contact with the upper surface of the floor soil 42 in the seedling raising box 8. In this state, seeds are put into the seed supply hopper 2, the seedling raising box 8 to which the bed soil 42 has been supplied is transferred by the transfer stand 15, and the clutch lever 72 is operated to be operated.
Switch 65 is turned on before meshing with each other, the brush-dedicated motor 51 is energized to rotate the rotation leveling brush 13 first, and the clutch passive gear 67 and the clutch drive gear 68 are rotated.
Mesh with each other to rotate the horizontal axis feeding roll 9.

Then, the seeds located below the rotary leveling brush 13 are returned to the seed pool 14, and the seeds in the seed supply hopper 2 flow down on the sling board 4 from the downflow port 5 to collect the seeds. The seeds are accumulated in the portion 14, and the seeds are fitted in the feeding recessed portion 10 of the horizontal axis feeding roll 9 in the seed pool 14, and the seeds are lifted by the rotation of the horizontal axis feeding roll 9 while being fitted, and the seeds of the rotary leveling brush 13 Excess seeds that pass below and co-rotate with the horizontal axis feeding roll 9 without fitting into the feeding concave portion 10 are swept back by the rotary leveling brush 13. Therefore, the feeding recess 10
The seed guide cover 40 with the horizontal row of seeds still fitted.
It is guided to the lower part by, and falls downward at the lowest point and is sown in the seedling raising box 8. Also, when seeding, if the operation lever 33 is lifted upward, the front turning arms 18, 18
Rotates upward about the horizontal shaft 26, and the gear 23 on the outer peripheral surface of the base of the front rotating arm 18 rotates the rear rotating arm 19 upward via the gear 25 to move the seed feeding device 1 upward. Let
The engaging shaft 47 of the arm 46 of the height adjusting mechanism 45 is engaged with the row-growing engagement groove 49, the row-growing guide 30 is attached below the horizontal-axis feeding roll 9, and the row-rolling roll 31 and the compression roll 32 are attached.
Is located at a height in contact with the upper surface of the floor soil 42 in the seedling raising box 8 and the seedling raising box 8 is transferred, and a groove 43 is formed on the upper surface of the floor soil 42 in the seedling raising box 8 by the stripping roll 31. The seeds that have fallen from the divided falling ports of the row sowing guide 30 are sown in the groove 43, and the crushing roll 32 collapses the mountain on the upper surface of the soil 42 to fill the groove 43 and complete the sowing.

In this case, although the height of the seed feeding device 1 is different between the row seeding and the scattered seeding, the chain 78 wound between the input gear 74 and the output gear 77 can correspond to the upper and lower sides of the input gear 74. Since the chain 78 is formed to have a length and the tension roller 86 acts on the chain 78, even if the input gear 74 moves up and down due to the vertical movement of the seed feeding device 1, the slack of the chain 78 corresponds to this. Tension roller 86
To absorb the slack of the chain 78 and keep the chain 7
8 can be tense. Then, the rotation leveling brush 13 is rotated by the brush dedicated motor 51,
The horizontal shaft feeding roll 9 transmits and receives the rotation of the transfer roll 75 of the transfer table 15 by turning on and off by the clutch mechanism 66, and the rotation leveling brush 13 and the horizontal shaft feeding roll 9 are respectively rotated by the rotation transmission mechanism of different systems. Therefore, since the rotation unevenness of the rotary leveling brush 13 does not affect the horizontal axis feeding roll 9 at all, the horizontal axis feeding roll 9 always rotates in synchronization with the transfer speed of the seedling raising box 8 and seeds at an accurate density. To be done.

However, the relationship between the horizontal axis feeding roll 9 and the rotary leveling brush 13 is such that, when the horizontal level feeding roll 9 is rotated, the rotary leveling brush 13 is started prior to the horizontal axis feeding roll 9, so that the rotary leveling brush 13 is temporarily rotated. Even if there are seeds below the brush 13, the rotation of the horizontal axis feeding roll 9 does not act so as to rotate together, so that the rotation of the horizontal axis feeding roll 9 does not resist the seeds, and the rotation leveling brush Only the rotation of 13 acts to surely sweep back to the seed pool 14. When the rotation is stopped, the rotation leveling brush 13 is stopped after the horizontal axis feeding roll 9, so that the horizontal axis feeding roll 9 is stopped.
The rotation leveling brush 13 continues to rotate even after the rotation of the seeds is stopped, and the seeds below the rotation leveling brush 13 are sown.
Return to 4. Therefore, the seed does not pass below the rotary leveling brush 13, so that the seeding accuracy is improved. At this time, since the rotation leveling brush 13 is configured to be rotated by the brush dedicated motor 51, control can be easily performed.

That is, a switch 65 for turning on / off the brush-dedicated motor 51 at a position closer to the disengagement side than the engaged position of the clutch mechanism 66 in the movement locus of the clutch lever 72 for operating the rotation of the horizontal axis feeding roll 9. Just provide
When the clutch lever 72 is turned on, the clutch lever 72 separates from the switch 65 before the clutch drive gear 68 meshes with the clutch passive gear 67, and the switch 65 is turned on. 13 rotates, and when the clutch lever 72 is moved in the disengagement direction, the clutch drive gear 68 is completely disengaged from the clutch passive gear 67, and the clutch lever 72 contacts the switch 65. Even if the rotation of 9 is stopped, the rotation leveling brush 13 continues to rotate and then stops. Therefore, the rotation control of the rotary leveling brush 13 is automatically performed in conjunction with the operation of the clutch lever 72 for rotating the horizontal axis feeding roll 9 to turn it on and off, and the operation is simple and there is no erroneous operation.

And a horizontal axis feeding roll 9 provided obliquely below the seed feeding hopper 2 and having a feeding concave portion 10 formed on the outer peripheral surface thereof, and a rotary leveling brush 13 provided substantially above the horizontal axis feeding roll 9. In the one provided with the
Since the horizontal axis feeding roll 9 and the rotary leveling brush 13 are used as seeding devices which are rotated by the rotation transmission mechanisms of different systems, the horizontal axis feeding roll 9 rotates the rotary leveling brush 13. Therefore, it precisely rotates in synchronization with the transfer roll 75 of the transfer table 15 to improve the seeding accuracy. Further, according to the present invention, on the transfer table 15 for transferring the seedling raising box 8 from the starting end to the terminal end, the seed supply hopper 2 provided on the upper part and the seed supply hopper 2 provided obliquely below the seed supply hopper 2 are fed to the outer peripheral surface.
