Above the rear part of the induction board 15, a rotary shaft 28 horizontally disposed on the left and right vertical base walls 1a, 1b is arranged, and the left and right vertical walls 1a, 1b are arranged.
The base ends of the left and right arms 29 extending forward between the two are fixed to the rotating shaft 28. An inverted truncated pyramidal guide cylinder 30 facing the bottom surface of the guide board 15 is fixed between the ends of the left and right arms 29, 29. A horizontally long outlet is provided in the lower portion of the guide cylinder 30, and the width of the horizontally long outlet corresponds to the inner width W of the guide board 15. Pivot axis
A base end of a lever 31 is fitted and fixed to one end of the vertical base wall 1a outside the 28. The lever 31 extends upward and frontward so that it can be stopped at an appropriate position by a lever stop device 32 which can be adjusted in position. The guide tube vertical position adjusting device 4 is configured as described above.

An example of the lever stopping device will be described. A central axis 41 of the disk photographing 40 is provided with a polymeric material circular ring seat 42 and is inserted into the vertical base wall 1a, and a nut 44 is screwed through a coil spring 43. A pin 45 projecting at an eccentric position of the photograph 40 is engaged with the tip bifurcated portion 33 of the lever 31. When the photograph 40 is rotated, the guide cylinder 30 moves up and down via the pin 45, the lever 31, the rotating shaft 28, and the arm 29. The distance H between the lower end of the guide cylinder 30 and the bottom surface of the guide board 15 can be adjusted by stopping the rotation position of the photographing unit 40 at an appropriate position.

The eccentric shaft 19 rotates in the direction of the arrow M, and sends the seeds forward on the guide board 15 which is arranged low at the rear while slightly flying.

The vertical portion 5 of the inverted L-shaped support member 54 is provided at the front of the vertical base walls 1a and 1b.
The lower end of 4a is fixed by a bolt 55. Bolt 55
It is possible to change the position of the upper end of the support member 54 by loosening and moving the support member 54 and tightening the bolt 55 again. There is a horizontal portion 54b at the upper end of the support member 54, and
4b is provided with a through hole 54c that faces vertically.

50 is a guide plate connected to the front end of the guide board 15 via a hinge member 51, and has a U-shape that opens upwards as a whole.
In addition, the bottom surface is provided with a large number of grooves 52 arranged in the front-rear direction.

The guide plate 50 is lowered toward the front, the lower end hook portion 56b of the hanging rod 56 that is obliquely forward and upward is hooked in the small hole 53 at the front end of the guide plate 50, and the upper portion of the hanging rod 56 is the supporting member horizontal portion 54b. It is prevented from coming off by an enlarged portion 56a provided through the through hole 54c slidably in the vertical direction.

When the eccentric portion 20 rotates in the direction of arrow M in FIG. 1 with the eccentric shaft 19 as the central axis, the center of the eyeball 21 moves circularly.
This circular motion is for spring plate 22, bracket 23, guide plate 15
1 to the hinge member 51, and the hinge member 51 also makes a small circular motion in the direction of arrow N in FIG.

In FIG. 4, when the hinge member 51 moves from the front side P to the bottom Q, the movement is very fast and the guide board 15 drops and moves backward, so that the seeds in the vertical groove 18 are It falls backward while receiving a backward force, and is in a state of being projected backward for a very short time. Then, when the dropped seeds contact the guide board 15, the guide board 15 passes through the lower Q and Qa
Since the front side P to Qa is Qb, the guide board 15
Is moved backward by QC, so the amount of backward movement of the seed relative to the induction plate 15 is small.

When the hinge member 51 moves from the lower Q to the rear lateral R, the seeds come into contact with the vertical groove 18, and the seeds in the vertical groove 18 become dense and have no spots.

When the hinge member 51 reaches from the rear lateral R to the upper T, the seed receives a forward force. When the hinge member 51 moves from the upper side T to the front side P, the downward moving speed of the guide board 15 is higher, so that the seeds are thrown forward and sent forward. When the dropped seed contacts the induction plate 15, the induction plate 15 is at Pa that has passed through the front side P and the head is Pb, and the induction plate 15 is moving by Pc. The amount of relative forward movement is large. Since Pb> Qb and Pc <Qc, the relative flight distance of the seed to the guide board 15 is larger in the forward direction, and the seed is gradually sent forward. The seeds at the front end of the induction board 15 fall on the guide plate 50.

That is, the seeds pass through the groove 52 of the guide plate 50 and are sown on the seedling raising box 3 in a state where there is no continuous gap.

When the front part of the guide plate 50 is lifted, the upper part of the suspension rod 56 moves upward in the through hole 54c, so that the seeding condition of the seedling raising box 3 located immediately below the guide plate 50 can be checked.

Further, the state of the guide plate 50 can be changed by loosening the bolt 55, displacing the support member 54, and then tightening it again.

[Effects of the Invention] Even if the seeds in the vertical grooves 18 of the guide board 15 have spots, the seeds pass through the grooves 52 of the guide plate 50 without a continuous gap, so that the seeds are spotted. It is sprinkled on the nursery box 3 without.

According to the present invention, excellent seeding without spots can be performed.

When the front part of the guide plate 50 is lifted, the upper part of the suspension rod 56 moves upward in the through hole 54c, so that the seeding condition of the seedling raising box 3 located immediately below the guide plate 50 can be checked.

Further, the state of the guide plate 50 can be changed by loosening the bolt 55, displacing the support member 54, and then tightening it again.
