BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a seedling box feeding device for a seeding device.

0002

2. Description of the Related Art Conventionally, as shown in FIG. 1, a large number of transfer rolls a are installed at predetermined intervals in the transfer direction between horizontal bars provided in parallel, and above are a bed soil supply device b, a seeding device c, In a device in which a seedling growing box feeding device f is provided on the starting end side of a transfer table e on which all or a part of a soil covering device d etc. is provided, the seedling growing box feeding device f has a guide horizontal frame g and a guide horizontal frame g. an upright guide member h provided at the front end of the guide member h, both supporting legs i provided at the front and rear ends of the guide horizontal frame g, and a motor-rotated transfer roll k (belt) provided on the guide horizontal frame g. (It may also be a transport structure)
Those formed from are known.

0003

The above-mentioned known examples have the disadvantage of being expensive. There are support legs i at the front and rear ends of the guide horizontal frame g,
The transfer roll k provided on the guide horizontal frame g is driven by an independent motor. Therefore, it is large in weight and volume, difficult to transport, and costs are considerably high. However, the transfer roll can be omitted from being attached to the guide horizontal frame, and the seedling box feeding device can be manufactured without the need for supporting legs at all. In this case, there is no transfer roll driven by an independent motor, and only one support leg is attached, so the weight and volume are small, and the cost can be significantly reduced.

[Means for Solving the Problems] Accordingly, the present invention provides a structure in which a large number of transfer rolls 2 are installed at predetermined intervals in the transfer direction between horizontal bars 20 provided in parallel, and a bed soil supply device 8 and a seeding device 9 are provided above. , a transfer table 1 provided with all or a part of the soil covering device 10, etc., and a pair of left and right guide horizontal frames 13 placed above the horizontal beams 20 on the starting end side 5 of the transfer table 1; An upright guide member 12 fixed to the front side of the guide horizontal frame 13
, a dropping mechanism for dropping the stacked seedling growing boxes 7 provided on the guide horizontal frame 13 one by one;
This is a seedling-growing box feeding device in a seeding device, which is comprised of a fixing fitting 31 that is fixed to the seedling box.

[0005]

[Example] An example of the present invention will be explained with reference to the drawings.
Reference numeral 1 denotes a transfer table, on which a large number of transfer rolls 2 are attached at predetermined intervals between horizontal bars 20 provided in parallel, and several supporting legs 3
It is placed on the floor surface 4 by the following steps. 5 is the starting end side of the transfer table 1, 6
is the terminal end, and when a seedling growing box 7 is supplied to the starting end 5, it is sent by a transfer roll 2 rotated by a motor, reaches the terminal end 6, and is taken out. On the transfer table 1, a bed soil supply device 8, a seeding device 9, a soil covering device 10, etc. are attached from the starting end side 5, and depending on the type, an irrigation device, a row spreading mechanism, and other mechanisms are attached.

Reference numeral 11 designates a seedling box feeding device of the present invention, which includes an upright guide member 12 provided on the tip side, and is placed from above on the starting end side 5 of the transfer table 1 and fixed to the transfer table 1 with a fixing metal fitting 31. The support leg 14 (not an essential requirement) is provided at the rear end of the guide horizontal frame 13. The lower end of the guide member 12 is fixed to the front side of the horizontal guide frame 13, and the upper end of the support leg 14 is fixed only to the rear side of the horizontal guide frame 13. The guide horizontal frame 13 is provided in a pair on the left and right, and the part between them has a hollow shape, and only the rear end has a roll 15.
(not a mandatory requirement) is installed. The seedling raising box supply device 11 is placed on the transfer table 1, and the seedling raising box 7 is placed on the guide member 1.
2 and stack them together, the lowermost seedling growing box 7 will be placed on the transfer roll 2 of the transfer table 1.

[0007] The seedling box supply device 11 is more convenient if it is automatically supplied. As shown in FIG. 4, the guide horizontal frame 13 is provided with a pair of upper and lower pins 16 that alternately go in and out. The pair of upper and lower pins 16 receive power from a solenoid 21 provided in a solenoid box 17, so that when the upper pin 16 comes out, the lower pin 16 retracts. To be more specific, the guide horizontal frame 13 is provided with a rotating shaft 23, the end of the rotating shaft 23 projects into the solenoid box 17, and a downward arm 24 is provided on one side and an upwardly directed arm 24 is provided on the other side. Mu25
are fixed respectively, and the downward arm 24 and the upward arm 2 are fixed.
5 are connected by a rod 26, and a solenoid 21 is connected to the rod 26.
The actuator 27 of is coupled. A spring 22 is attached to the actuator 27. The rotating shaft 23 is provided with a swinging body 29 having notches 28 at the top and bottom, and the notches 28 are engaged with pins 30 provided in the upper and lower pins 16. The device allows the seedling growing boxes 7 to be dropped one by one onto the transfer roll 2 of the transfer table 1. The sensor 18 that detects the completion of transfer of the seedling box 7 sends an activation signal to the solenoid, and this may be a cam or a phototube. The pair of upper and lower pins 16 are provided at four locations on both the front and rear sides.

[0008] The guide horizontal frame 13 needs to be raised slightly upward in consideration of the fall distance of the seedling box 7. In this case, if the horizontal guide frame 13 were made wider in the vertical direction, the shape would deteriorate, so a pedestal 19 was attached. The base leg 19 is welded and fixed to the lower surface of the guide horizontal frame 13, and also functions for positioning.

[0009]

[Effect] Next, the effect will be described. The guide horizontal frames 13 are a pair of left and right, but except for the roll 15 provided at the rear end, they have a hollow shape. When the transfer rolls 2 of the transfer table 1 are placed on the guide frame 13 and fixed with the fixing fittings 31, several transfer rolls 2 (three in the embodiment) of the transfer table 1 will be exposed to the bottom surface of the horizontal guide frame 13. Approximately 10 empty seedling growing boxes 7 are placed above the transfer roll 2.
When stacking them and aligning them, the collar of the bottom seedling box 7 will be
It hits the protruding lower pin 16 and stops. That is, when the solenoid 21 provided in the solenoid box 17 is energized, the actuator 27 pulls in against the elasticity of the spring 22, moves the rod 26, and rotates the downward arm 24 and the upward arm 25. , rotates the rotating shaft 23. The rotating shaft 23 is provided on the guide horizontal frame 13, and a swinging body 29 having vertical notches 28 is fixed to the rotating shaft 23.
is engaged with the pin 30 of the upper and lower pins 16, so the upper pin 16 of the upper and lower pins 16 is retracted and the lower pin 16 is protruded, and when about 10 empty seedling boxes 7 are stacked and aligned, the bottom row The protruding lower pin 16 is located at the collar of the seedling box 7.
It hits and stops.

Therefore, when the sensor 18 that detects the completion of transfer of the seedling growing box 7 is manually operated for the first time to make it the same as when the seedling growing box 7 has been transferred, the energization of the solenoid 21 provided in the solenoid box 17 is cut off. , the actuator 27 is protruded by the elasticity of the spring 22, the lower pin 16 is retracted, and at the same time the upper pin 16 is protruded, so that only one seedling box 7 falls onto the transfer roll 2 of the transfer table 1 and is transferred. Once the seedling growing box 7 is transferred, the sensor 18 is activated and the seedling growing box 7 is automatically supplied, so the operator only has to add the seedling growing box 7.
