[0015]
The above is similar to that previously apparatus Cree entitled acquired Patent No. 2,939,806 to the configuration, by the adsorption for a flat plate 4 the electrical vibration equipment of in seeds in the present invention, are finely vibrate It is constructed as follows.
[0016]
26 is a band plate arranged so as to slightly vibrate the back side portion of the upper side opposite to the pocket portion 9 of the seed adsorbing flat plate 4, which is approximately the same width as the width of the seed adsorbing flat plate 4. And is arranged in parallel to the back side of the upper side of the seed adsorbing flat plate 4. An electric vibration device 27 is fixed to the back surface side of the box 5 and includes an electromagnet motor 27a inside, and its vibration shaft 27b is connected to the center position of the belt plate 26.
[0017]
At this time, when the belt plate 26 is relatively long, support bases 28a and 28a for supporting the belt plate from below are provided on the way from the central position to the other end. On the other hand, an anti-vibration rubber 29 is interposed on the contact surfaces of the support bases 28a and 28b with the bottom surface of the box body 5 so that vibrations do not propagate to the bottom surface of the box body. It is an elastic material such as urethane resin or rubber, and is brought into contact with the back surface of the seed adsorbing flat plate 4 through the elastic material, and 31 is the electromagnet motor 27a provided on the side wall surface 6a of the box. This is a vibration switch. On the other hand, when holding and swinging the box of the seed adsorbing plate 1 by hand, the seed adsorbing flat plate 4 is slightly vibrated by appropriately turning on and off the switch 31.
[0018]
The present invention is configured as described above. Next, the overall use will be described. First, by operating the wing nut 17 and moving the three positioning plates 13, 14, and 16 as necessary , the position and size of at seedling tray support area in supporting Jidai apparatus 2 appropriately determined.
[0019]
Thereafter, one seedling tray 3 in which floor soil is put in each pot portion 3a is placed on the seedling tray support range from above, and its left side surface is brought into close contact with the left positioning plate 16. As a result, the seedling tray 3 is supported at the bottom by the mounting plate 15, the left side is positioned by the left positioning plate 16, the front and rear sides are positioned by the front and front positioning plates 13, 14, and the periphery is 3 It is supported by the upper edges of the two positioning plates 13, 14, 16.
[0020]
On the other hand, as shown in FIG. 1, the seed adsorbing disk 1 is supported on the spherical surface by swinging around the support shafts 11 and 11 while the support shafts 11 and 11 are fitted in the grooves of the receiving members 19 and 19. It is assumed that the body 21 is fitted in the engaging member 10. Thus the seed suction cup 1 is in a state held in the inclined state shown in FIG. 1 by supporting Jidai device 2.
[0021]
Under this state, a large number of seeds w (see FIG. 2) such as vegetables having a diameter of about 0.3 to 1 mm, for example, to be sown on the seed adsorption flat plate 4 of the seed adsorption board 1 are supplied. The seed w group supplied in this way flows downward on the seed adsorption flat plate 4 by its own weight and is accommodated in the pocket portion 9.
[0022]
In addition, an air suction device (not shown) is operated to open the on-off valve 24 and to appropriately restrict the throttle valve 25 so that a space h (between the seed adsorbing plate 4 and the bottom wall 5 of the seed adsorbing plate 1 is obtained. Air is sucked at an appropriate flow rate from (see FIG. 3). As a result, air is sucked from each air suction hole 4a with an appropriate momentum.
[0023]
Next, under the state where the seed adsorbing plate 1 is supported by the spherical support 21 through the engaging member 10, the left and right portions near the pocket portion 9 of the seed adsorbing plate 1 are held by hand and pulled out toward the front. as the support shaft 11, 11 is disengaged from the receiving member 19, 19 of the supporting Jidai device 2 further right and left portions of the pocket portion 9 near is swung upward, roughly horizontal posture seed suction cup 1. At this time, since the weight of the seed adsorbing board 1 is supported by the spherical support 21, a large load does not act on the hand of the operator.
[0024]
Thereafter, as shown in FIG. 4, the hand holding the seed adsorbing plate 1 is moved up and down, so that the seed adsorbing plate 1 is repeatedly rocked appropriately in the front-rear and left-right directions. Thereby, the seed w group in the pocket portion 9 flows forward, backward, left and right on the seed adsorption flat plate 4, and the seed w located on each air suction hole 4a is adsorbed by the negative pressure acting on the suction hole 4a. In the end, one or several seeds w are adsorbed to all the air suction holes 4a. However, if the cortex has a large frictional resistance during the above operation and is not slippery, it may be by by inputting vibration switch 31 is finely vibrated seed attraction flat plate 4, tighten if facilitate the activities of floating seeds other than seeds w adsorbed by suction holes 4a, arrive suction holes of these seeds w group Adsorption to 4a is performed quickly.
[0025]
After performing over an adsorption operation of such seeds w in a proper time, the Ru lowering the hand holding the seed suction cup 1, seeds w other than seeds w adsorbed by the air suction hole 4a by its own weight on seed attraction flat plate 4 descends downwards is again accommodated in the pocket portion 9.
[0026]
After the seed w is completely adsorbed in this way, the seed adsorbing board 1 is held by hand and is swung downward around the support shafts 11 and 11 so as to be reversed. As a result, the left and right ends of the front portion of the seed adsorbing plate 1 are supported by the seed adsorbing plate supporting portions 22 and 22. As a result, the seed adsorption flat plate 4 of the seed adsorbing board 1 is close to the seedling raising tray 3 and faces in parallel, and one air suction hole 4a and one pot portion 3a correspond to each other. In this operation, since the weight of the seed adsorbing board 1 is supported by the receiving members 19, 19, a large load does not act on the operator's hand.
[0027]
Next, the on-off valve 24 is closed. As a result, the air suction force of each air suction hole 4a disappears, so that the seed w adsorbed by each air suction hole 4a falls freely and reaches the floor soil in the corresponding pot portion 3a.
[0028]
If this again seeds w is such that it does not fall spontaneously caught on the air suction hole 4a, the operator moving switch 31 or vibration tapping lightly tapping by hand side of the seed suction cup 1 as this countermeasure Is turned on to vibrate the flat plate 4 for seed adsorption. As a result, the seed w caught in the air suction hole 4a is reliably separated and dropped. The fallen seed w is reliably sown in each pot portion 3a.
[0029]
【The invention's effect】
According to the above-described present invention, it is possible to quickly and accurately adsorb seeds to the seed adsorption flat plate even if the seed adsorbing plate has poor slippage due to the operation of the electric vibration device. is there. Since the band plate is brought into contact with the back side of the upper side of the seed adsorption flat plate, the air suction hole is not drilled in the portion of the seed adsorption flat plate. Thus, the air suction hole is not blocked from the back surface, and the adsorption efficiency is not lowered.
