2. Description of the Related Art The applicant of the present invention is
A technology for temporarily placing cell-formed seedlings in a temporary placement cup of a seedling transfer device and transporting them and then temporarily planting them in a temporary planting tray from this temporary placement cup has been applied (Japanese Patent Application No. 7-17210). This temporary planting device sends cell-formed seedlings grown by a cell-formed seedling tray with pots (recesses) arranged in a grid pattern one by one, and temporarily places them one by one by the seedling extractor in the seedling transfer cup. It was configured to be transported to the planting section by the loading and transporting device and temporarily planted in the temporary planting tray at the planting section.

[0003]

However, since the cup of the above-mentioned seedling transfer device of the temporary planting apparatus has one size, the type of seedling to be temporarily planted is the size at the time of cell molding seedling. Is limited to several types of seedlings of approximately the same size. That is, there are several cell pot sizes for cell-molded seedling trays, and cell-molded seedling trays to be planted are selected according to the type of crop to raise seedlings. When the cell-formed seedlings grow to a size that allows temporary planting, they are transplanted to a slightly larger pot tray by a temporary planting device. But,
If the cell-formed seedling is smaller than the temporary placement cup of the temporary planting device, a gap is created between the outer circumference of the root pot of the cell-formed seedling (the frusto-conical soil of the cell-formed seedling) and the inner circumference of the cup, and the removal is performed. Claws on the part of the plant or the claws on the planting part could not be held because they did not enter the root pot, there was a displacement in the cup, there was a position shift in the pot of the temporary planting tray, and there were variations in the planting depth. Of.

[0004]

The problems to be solved by the present invention are as described above. Next, the means for solving the above problems will be described. That is, the cell-formed seedlings germinated in the cell-formed seedling tray P are conveyed by the seedling tray conveyor 10, and the cell-formed seedlings are transferred to the seedling transfer / conveyance device C by the seedling extracting section E during the transfer. The seedling transfer / conveyance device C conveys the cell-formed seedlings to above the temporary transplant tray conveyor 11 and the temporary transplanting tray is temporarily transplanted by the planting section B. A plurality of types of cups having different hole sizes and depths are provided. The cups are arranged in parallel in the transport direction for each type and provided in the seedling transfer / transport device C, and the heights of the upper surfaces of the cups are matched.

Further, in the front-back lifting mechanism for moving the head for holding the cell-formed seedlings in the seedling extraction section E and the planting section B between the upper position of the seedling transfer device C and the upper position of the tray, A stopper is provided at a stop position in the upper position, and a plurality of stop positions in the front-rear direction are provided on the stopper so that the stopper can be selected according to the type of cell-forming seedling, and the tip of the claw when the head is lowered is the above-mentioned each. A vertical stop setting position, which is a predetermined distance from the bottom of the hole of the cup, is provided in the roller guide of the front-rear lifting mechanism.

[0006]

Next, the operation will be described. The cell-formed seedlings raised in the cell-formed seedling tray are conveyed by the seedling tray conveyor 10 to the seedling transfer device C, and the seedling extraction unit E extracts the cell-formed seedlings from one row of the cell-formed seedling tray P.
It is transported to the upper front. The stop position at this time is selected from the front and rear positions of the stopper in accordance with the size of the cell-molded seedling, and is stopped above the temporary storage cup 9 that matches the size of the cell-molded seedling on the seedling transfer / transport device C. The cell forming seedling is lowered by the lifting cylinder of the seedling extracting section E to insert the cell forming seedling into the temporary storage cup 9, the seedling extracting section E returns to the original position, and the cell forming seedling on the next cell forming seedling tray is extracted. . Then, the seedling transfer / conveyance device C conveys it to the temporary planting tray conveyor 11, and the planting section B is moved to a position corresponding to the size of the cell-formed seedling, as in the front-rear lifting mechanism of the seedling extracting section E. The cell-formed seedlings are taken out from the temporary-placement cup 9 of the seedling-transferring and conveying apparatus C in which the cell-formed seedlings are inserted, and are planted on the temporary-planting tray S on the temporary-planting tray conveyor 11.

As shown in FIG. 12, the upper end of the roller guide 15 is provided with a curved portion 15b, and the height when the seedling extractor E is stopped above the seedling transfer device C is the root pot of the cell-formed seedling. Two positions (59 and 5)
9 ') can be selected. That is, the selection of the stop setting position is performed by the stopper 60 described later.
The reason why it has to be two positions is that the tip of the withdrawing claw 5 for withdrawing the cell-forming seedlings is placed in the temporary cup 9 formed by matching the upper surfaces of the cups 9a and 9b having different sizes and depths. In order to allow the cups 9a and 9b to be inserted at a predetermined height from the bottoms, the heights at which the cups 9a and 9b are supported are different. That is, the depth difference L1 between the cups 9a and 9b in FIG.
The roller 59 by the curved portion 15b in FIG.
Is made equal to the lifted distance L1, and the distance between the tip and the bottom when the extraction claw 5 is inserted is always constant even if the cup is changed.

Further, the position changing distance L2 of the stopper 60 for selecting the cup 9a and the cup 9b is set to the cup 9a.
And the distance L2 between the cup 9b and the cup 9b. As shown in FIGS. 8 and 9, the stopper 60 is arranged so as to come into contact with the front surface (left side surface in FIG. 8) of the seedling picking support 22, and a shock absorber is incorporated in the stopper 60 to make contact with it. I try to absorb the shock of time. The front side of the stopper 60 is fixed to the sliding body 61, and the sliding body 61 is fixed to the frame H3.
It is guided so as to be slidable back and forth along 2 and is fixed to the tip of the piston rod of the cylinder 63 fixed to the frame H3. By expanding and contracting the cylinder 63, the contact position of the stopper 60 can be moved by the distance L2, the stop position of the seedling picking support 22 in the front-back direction can be set, and it can be used as a root pot for cell-forming seedlings. It can be selected together. The expansion / contraction position of the cylinder 63 is detected by the sensors 64a and 64b, and the sensor is connected to the controller.

Further, a mounting plate 65 is fixedly provided in the middle part of the rear part of the seedling picking support 22.
The tip of the piston rod 16a of the slide cylinder 16 is connected to. The slide cylinder 16 has its upper part pivotally supported by a bracket 67 fixed to the frame H3 so that the cylinder can rotate when expanded and contracted.

It abuts against the seedlings to soften the shock at the time of stopping and to prevent the grasped seedlings from falling while stopping. By expanding and contracting the slide cylinder 16, the seedling picking roller guide 15 and the seedling picking support 22 move along the guide rails 23 and 56, and the seedling picking section E moves up and down and back and forth at the same time. It can be stopped at a position above the seedling transfer / conveyance device C and a position above the cell forming seedling tray P.

The front-back raising / lowering mechanism of the planting support 21 on the side of the planting section B has substantially the same structure as the front-back raising / lowering mechanism of the seedling extracting section E, and as shown in FIG. Is connected to the slide cylinder 17, the slide cylinder 17 is pivotally supported by a bracket fixed to the frame H3, and the stopper is arranged in the same manner as described above. By extending and contracting the slide cylinder 17, the roller guide 25 and the guide rail The planting support 21 moves along 24, and the planting part B moves up and down and back and forth at the same time.
The seedling transfer device C and the temporary planting tray S can be reciprocated. In this way, both the seedling extraction section E and the planting section B are simultaneously moved in the front-rear direction and the vertical direction by one cylinder respectively, and are placed at two positions in the upper position of the seedling transfer / conveying device C in accordance with the temporary storage cup 9. One of them can be selected and stopped, and can also be stopped at a position above the temporary planting tray S. However, when three or more types of cups are arranged in parallel, the same number of stop positions as those types are formed.

Next, the structure of the seedling picking head portion of the seedling picking section E will be briefly described with reference to FIGS. This seedling picking head portion is lifted and lowered by a cylinder 27 with a lifting guide fixed to the seedling picking support 22 at an upper stop position of the cell-forming seedling tray P and an upper stop position of the seedling transfer device C. A pantograph type pitch changing mechanism 75 is provided at the lower end of the piston rod and the guide rod of the lifting guide cylinder 27, and a plurality of seedling extracting bodies provided with extracting claws or the like so that the pitch changing mechanism 75 can change the left and right pitches.

By doing so, the planting nail 6 can be opened and closed. However, the elevating cylinder 33 can be independently expanded and contracted, so that when the missing or dwarf seedlings are conveyed, the cell forming seedlings of the temporary storage cup 9 in which the missing or dwarf seedlings are detected by the sensor are not captured. This is because

A support frame 26 is provided so as to project forward from the middle of the pillar H2, a guide rail 14 is provided in the support frame 26 in the horizontal direction, and a slide support 18 is slid left and right on the guide rail 14. The sliding support 1 can be freely fitted.
The upper end of 8 is fitted in the guide rail 13 so as to be vertically slidable. The upper and lower cylinders 47 are vertically fixed to the sliding support 18, and the same number of holes as the row of temporary planting pots of the temporary planting tray S are provided at the tip of the piston rod of the upper and lower cylinders 47. are doing. Therefore, in accordance with the transportation of the temporary planting tray conveyor 11, it moves back and forth at the same time as the planting section B, and vertically moves the piercing rod 8 by expansion and contraction of the upper and lower cylinders 47, before planting by the planting section B. A hole having the size of the root pot of the cell-formed seedling is made in the planting pot. The piercing rod 8 can be replaced according to the size of the root pot of the cell-shaped seedling.

Therefore, the planting part B is located at a position just above the temporary cup 9, the planting claw 6 is opened and lowered to capture the cell-forming seedlings, and then the lifting cylinder 33 is contracted to reduce the cell. The molded seedling is taken out from the temporary storage cup 9, the slide cylinder 17 is reduced and lowered, and the planting claw 6 is moved to the temporary planting tray S.
Move up and plant cell-forming seedlings in pots. At this time, whether or not the leaf portion of the cell-formed seedling placed on the temporary placement cup 9 is normally grown is detected by a sensor (not shown) attached to the seedling transfer device C. Only when the leaves of cell-formed seedlings are growing normally
Each of 6 ... is independently extended and moved to the seedling capturing position, and only the normal cell-formed seedlings are taken out from the temporary storage cup 9 by the above-mentioned operation, and the abnormal cell-formed seedlings are not supplemented. The cell-forming seedlings at the top of the plant, which have been conveyed to, are successively expanded and contracted to be captured by all the plant B and planted in pots. The abnormal cell-formed seedlings are dropped into a collection container 49 provided below the left end of the seedling transfer / transport device C.

After the transfer of the seedlings, the empty temporary storage cup 9 is cleaned at the lower side and the side of the conveyance. That is, as shown in FIGS. 1 to 6, the mounting bracket 80 is located laterally of the left frame base H.
Nozzle 81 that blows out air is provided on the mounting bracket 80 to blow off dirt, dust, etc. adhering to the inside of the empty cup, and the abnormal cell-formed seedling that has not been planted is forcibly forced to the collection container 49. I'm trying to get out and fall.
In addition, the mounting bracket 8 is provided to the side of the right frame base H.
2 is attached and a nozzle 83 for blowing out air is attached,
The cup after being immersed in the cleaning tank 12 and cleaned is dried by the air discharged from the nozzle 83. The drive motor M, the sensor, the electromagnetic valve for supplying air to the cylinder, and the like are connected to and controlled by a controller.

[0027]

Since the present invention is constructed as described above, it has the following effects. That is, as in claim 1,
Since multiple types of cups are arranged in the seedling transfer / transport device C, it is possible to select the cups according to the size of the seedlings grown in the cell-forming seedling tray and temporarily plant them in the temporary planting tray. As a result, the number of types of crops that can be temporarily planted can be increased, and small seedlings will no longer be misaligned in the temporary placement cup and cannot be grasped well, and reliable temporary planting will be possible. In addition, regardless of the type of cup, the height of the upper surface of the cup is set to the same height, so that the dead zone of the sensor for detecting abnormal cell forming seedlings or missing strains does not occur.

[0028] Further, as in claim 2, the seedling transfer device C
At the stop position on the upper side, we provided a stopper that allows you to select the stop position according to the type of cell molding seedling, so by selecting the stopper, you can select the cup and transfer it, It is not necessary to control the drive side of the front-rear lifting mechanism, which simplifies the control configuration. Further, since the roller guides of the front-rear lifting mechanism are provided with vertical stop positions at which the tips of the claws of the seedling extracting section E and the planting section B are located at a predetermined distance from the bottoms of the holes of the cups, the tips of the claws are located at the bottoms of the holes. On the other hand, the cell-shaped seedlings can always be stopped at a fixed position, the cell-formed seedlings can be grasped at a fixed position, and the planting depth also becomes constant.
