Abstract

PURPOSE:To sharply reduce manufacturing cost by providing a guide side frame with a pair of upper and lower pins, which go in and out alternately, and providing it with a going in and out operation mechanism for pins, at an optional position, and a sensor for operating the going in and out operation mechanism. CONSTITUTION:When guide side frames 13 accommodate a raising seedling box supply device 11 so that it may lie upon the top of the start end 5 of the transfer table 1, it follows that several pieces of conveying rollers 2 of the transfer table 1 front on the bottom of the guide side frames 13. If the raising seedling boxes 7 are arranged properly in piles at the position above the transfer roller 2, the brim of the raising seedling box 7 on the lowermost stage hits the projecting lower pin 16. If a sensor 18 for detecting the transfer completion of the raising seedling box 7 is operated by hand so as to simulate the transfer of the box 7 only at the first stage, the lower pin 16 retreats and at the same time the upper pin 16 projects, so the box 7 falls only one piece onto the transfer roller 2 of the transfer table 1, and is transferred. When the box 7 is transferred, thereafter, the sensor 18 functions, and it is supplied automatically.

[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 side, and when the seedling growing box 7 is supplied to the starting end side 5, it is sent by the transfer roll 2 rotated by a motor, reaches the terminal end side 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 denotes a seedling box feeding device of the present invention, which includes an upright guide member 12 provided on the tip side, a guide horizontal frame 13 placed from above on the starting end side 5 of the transfer table 1, and a guide horizontal frame 13 placed on the starting end side 5 of the transfer table 1 from above. It is mainly formed from a support leg 14 (not an essential requirement) provided at the rear end of the frame 13. The guide member 12 is the guide horizontal frame 1
The lower end portion is fixed to the tip side of 3, and the supporting leg 14 is attached to the guide horizontal frame 13.
The upper end is fixed only on the rear side.

[0007] The guide horizontal frame 13 is provided in a pair on the left and right,
The space between them is bottomless, and a roll 15 (not an essential requirement) is attached only to the rear end. Seedling box supply device 1
1 on the transfer table 1, and stack the seedling raising boxes 7 against the guide member 12 in alignment, the lowermost seedling raising box 7 is placed on the transfer table 1
It will be placed on the transfer roll 2 of.

[0008] It is more convenient if the seedling box supply device 11 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 provided in a solenoid box 17, so that when the upper pin 16 comes out, the lower pin 16 retracts. By repeating this operation, the seedling growing boxes 7 can be dropped one by one onto the transfer roll 2 of the transfer table 1. The sensor 18 that sends the activation signal to the solenoid to detect the end of transfer of the seedling box 7 may be a cam,
It can be a phototube or anything else. The pair of upper and lower pins 16 are provided at four locations on both the front and rear sides.

[0009] 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. When the pedestal 19 has the structure shown in the figure, it also functions for positioning.
