2. Description of the Related Art In horticulture and greenhouse cultivation, potting work has generally been done manually by hand. The soil used is not only various types of culture soil but also shale crushed soil mixed with pebbles. There are many. In addition, holes for planting seeds or transplanting seedlings are often dug by hand in pots that have been put in soil. Further, in forming a hole for transplantation, Japanese Patent Laid-Open No. 7-
No. 31220 describes a clay hole forming device that forms a hole in a pot containing soil, one by one, so that uniform holes can be quickly and in large numbers.

[0003]

On the other hand, there is a demand for more and more rapid formation of holes, and continuous treatment of soil filling and digging is also required. For this continuous treatment, there are proposals described in JP-B-54-33881 and JP-B-54-33882, in which each pot is placed on a pot support stand arranged in an annular shape and circulated, and is provided at a predetermined position. This can be done by sequentially passing individually through the "soil supply position" and the subsequent "hole digging device". However, since each pot is processed individually, there is a limit to the speed, and there is no disclosure of the technique of soil filling and digging corresponding to the size of the pot. In addition, the one that treats a large number of bowls at a time is,
There is a proposal described in Japanese Patent Publication No. 09, in which a "cutting die", which is a model of a seedling, is inserted into a large number of pots positioned on a pallet, and soil is supplied from an upper hopper. is there. However, it is necessary to "scratch the soil that has been supplied" by hand, and "excess soil" will also come out after scratching.
Further, like the above-mentioned proposal, it is difficult to supply an appropriate amount of soil for each size of the pot, and the pot is worn out and becomes full. Furthermore, according to the type of “cutting die”, the shape of the hole is relatively likely to lose its shape during the transplanting work, which is a problem.

In view of these problems, it is an object of the present invention to provide a proper amount of soil by suppressing the soil filling into pots positioned by a pallet or the like, and by suppressing excess soil. A multi-hole formation that can form a large number of holes more quickly than in the past by connecting a potting device that can do so and a potting device that can make a hole collectively to multiple pots containing soil To provide a machine.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Next, an embodiment of the present invention will be described with reference to the drawings.

(Description of Structure) The embodiment of the multi-hole forming machine for pots for transplant shown below is as follows. As shown in FIGS. 1 and 2, soil is placed in pots A arranged in a predetermined arrangement on a pallet B. The soil filling device 1 for storing the pallet B and the pallet B that has been soiled by the soil filling device 1 are automatically conveyed and positioned in the downstream digging device 2 in synchronization with the completion. Described later,
A plurality of digging bodies 42 are provided with a digging device 2 facing the bowl A on the pallet B, and a control means for controlling the soil putting device 1 and the digging device 2.

(1) Description of Soil Filling Device 1 As shown in FIGS. 3 and 4, the soil filling device 1 is a soil supplying unit 10 for discharging soil to a fixed position and a receiver for discharging the soil. The bowls A are sequentially received by positioning the mounting table 20.

First, the soil supply unit 10 includes a hopper 11 and
Two first screws 12 that are horizontally arranged side by side to feed soil from the bottom of the hopper 11 and serve as a spiral conveyor.
A conveyor belt 13 for conveying the soil fed to the first screw 12, a funnel portion 14 provided below the end of the conveyor belt 13 for receiving the soil conveyed by the conveyor belt 13, and the funnel. It has a discharge pipe 15 for finally supplying the soil from the portion 14 to the pot A.

At the bottom of the hopper 11, as shown in FIGS. 5 to 7, a shallow screw box 51 having an upper opening.
However, it is formed so as to receive the soil. Further, the soil thus received is fed out by the first screw 12 installed in the screw box 51. At this time, the side wall 52 of the screw box is tapered, so that the soil of the hopper is guided to the first screw 12. Further, in the case of soil that is hard to collapse such as damp soil or clay soil, when the soil is fed out, a void of soil may be formed around the first screw 12. Therefore, the subsequent soil is the first screw 12
I couldn't reach the ground and the soil was cut off. Therefore, in order to avoid this, the cavity is broken and the first screw 1
In order to allow the soil to flow into 2, the three stirring shafts 53 are laid in parallel on both sides of each of the two first screws 12, and the stirring shaft 53 has a rotating claw 54 that is in a cross shape with the shaft 53. Is provided so as to rotate at low speed together with the stirring shaft 53. There are other methods for breaking the cavity, for example, a claw can be attached to the outer circumference of the blade of the first screw to scrape and break the cavity.

Further, the discharge pipe 15 is a long cylindrical pipe, and as shown in FIG. 8, a second screw 16 serving as a spiral conveyor is provided in the entire length of the funnel portion 1 as shown in FIG.
The soil from No. 4 is taken in through the intake port 15a which is formed by cutting out the upper side surface on the one end side of the discharge pipe 15 into a substantially rectangular shape, and the second screw 1
6 is used to move the inside of the pipe and discharge from a discharge port 17 extended to a fixed position above a mounting table 20 described later.

This will be described in more detail. Second screw 1
Reference numeral 6 is formed by cutting out aluminum, which is excellent in workability, as a material, and is composed of a shaft portion 61 and blades 62. The blade 62 is formed to have a thickness of 10 mm, and conveys the soil taken in from the intake port 15a to the discharge port 17. The radius of the outer peripheral surface 63 of the blade outer surface 63 near the conveyance surface C is 8 to 10 mm as shown in FIG.
It is chamfered in a circular arc shape. This is the funnel part 14
This is because pebbles and the like mixed in the soil when the soil is taken in may be sandwiched between the intake 15a and the blade 62. That is, as shown in FIGS. 10 and 11, pebbles sandwiched between the short side portion 64, the long side portion 65 or the corner portion 66 of the intake port 15a stop the movement of the second screw 16,
In this embodiment, the chamfered blades 62 are provided on the blade outer periphery 63 to allow the pebbles to escape, and the smooth rotation of the second screw 16 can be maintained. However, even with the chamfered blades 62 in this way, there is still a possibility that pebbles may be caught, so the long side portion 65 of the intake port 15a is a rubber plate extending from the funnel portion 14 as shown in FIG. 13 and a corner portion is also covered with a guide 67 made of a rubber plate so as to close the corner, as shown in FIGS.
In step 7, pebbles can be more reliably avoided. In addition, the second screw 16 includes a drive portion 68 as shown in FIG.
It is also possible to use a screw conveyor that has the shaft portion 61 only in the above and has made the shaft portion emptied over the other entire length. This is because the use of such a screw conveyor has the advantage of increasing the transport amount even at the same number of rotations.

The discharge port 17 is provided with a supply sensor 18 for sequentially measuring the surface height of the soil supplied to the lower pot A. Although the outlet 17a of the discharge pipe 15 may be directly used as the outlet 17 as in the embodiment, the outlet 17a of the discharge pipe 15 is provided with a rectifying portion 71 as shown in FIG. Outlet 72 to outlet 17
It may be. The straightening unit 71 has an inlet 73 and an outlet 72.
Are in a substantially right-angled directional relationship, and are connected by a gently curved inner cylinder 74 during that time, and are for rectifying the soil sent from the discharge pipe 15 downward. Also, the inner cylinder 7
No. 4 is a slight sloping groove, and a large number of grooves 75 are engraved from the inlet 73 to the outlet 72. Can be supplied.

The mounting table 20 is a table having a substantially square plane.
The base frame 21 and the X stand 23 that is installed on the base frame 21 and moves in the X direction
And a Y base 26 which is installed on the X base 23 and moves in the Y direction as a main structure, and as a result, the Y base 26 is configured to move in a substantially horizontal plane in the XY directions.

More specifically, the mounting table 20 includes a base frame 21 and two X rails 22 arranged side by side on the upper side of the base frame.
And an X stand 23 movably installed on this X rail 22
And an X motor 2 for moving the X base 23 in the X direction.
4 and a belt are provided. Then, on the upper side of the X base 23, two Y rails 25 that are perpendicular to the X rail 22 are arranged side by side, and a Y base 26 movably installed on the Y rail 25 and the Y base 26 are provided. A Y motor 27 and a belt for moving in the Y direction are provided. And furthermore
On the Y table 26, a guide plate 28 for positioning when placing a pallet B or the like into which the bowls A are arranged is erected in a two-sided plane at right angles.

In the above embodiment, since the hopper having a capacity of about 0.5 m ³ is used and the hopper is set at a relatively low position near the ground, it is easy to fill the soil from above the hopper. Further, since the second screw is made of aluminum, it is difficult for soil to adhere to it. The term "continuous soil supply" means that soil is supplied little by little to a pot, and the supply amount can be arbitrarily adjusted by continuing or stopping this supply. Therefore, for example, if you want to drop the soil directly from the bucket conveyor,
The amount of soil in the pot does not increase continuously, but increases stepwise by the amount commensurate with the bucket, so the soil may overflow at the last cup, so the amount of soil supply cannot be adjusted arbitrarily. However, this is something that can be avoided.

(2) Description of the digging device 2 Next, one mode for carrying out the digging device 2 will be described. As shown in FIG. 17, this digging device 2 includes a base 31 and a base 3
1, a supporting column 32 standing upright, a top plate 33 fixed to the upper end of the supporting column 32, and a lift table 34 supported by the top plate 33.

8a is vertically pierced vertically through the lifting table 34 and is axially supported. A drive gear 38b at the lower end of the shaft 38a meshes with a gear 45a on the side of the excavation head 40 to form a plurality of hole excavation bodies described below. 42
Is finally driven to rotate.

The digging head 40 mainly comprises a board 41 to be inserted into the concave groove of the fitting rail 37 and a plurality of hole digging bodies 42 axially supported so as to hang down on the board 41 when attached. It is configured. The hole-drilling body 42 is vertically provided in correspondence with the arrangement of the bowls A arranged on the pallet B, and the plurality of these holes are formed through the gear portion 45 provided on the upper surface of the substrate 41 by the drive gear 38a described above. The hole moat 42 of the same direction at the same time
It is designed to rotate at the same speed.

This digging body 42 is pushed into a pot A containing soil to dig a hole in the soil, as shown in FIGS.
A soil scraping portion 43 for rotating the soil at the lower end face of the inverted truncated cone to scrape the soil in the centrifugal direction, and pressing the scraped soil on the side face of the inverted truncated cone to form the side wall of the soil hole. And a pressing portion 44. The soiling portion 43 is an iron disc, and a claw portion 43a protruding in a wavy shape is provided on the lower end surface in the diameter direction of the disc, and a large number of spiral grooves are formed from the claw portion. 43b is engraved so as to reach the circumference, and the soil is separated in the centrifugal direction. Pressing part 44
Is made of plastic in the shape of a pot, so that it is difficult for soil to attach to it, and it is possible to form a hole matching the shape of the soil of the seedling, which is taken out from the pot before transplantation.

A stabilizing plate 46 is supported below the substrate 41 to hold the bowl A from the top and stabilize it when digging. The stabilizing plate 46 is an iron plate having substantially the same shape as the substrate 41, and the holes 46 a through which the hole-digging body 42 can pass are provided in the same arrangement as the hole-digging body 42. And the hole moat 42

Since the moat head can be replaced, the size of the bowl
The versatility of the hole excavator will be expanded by preparing a moat head suitable for the arrangement and replacing it as necessary.

(3) Description of the control means The control means does not show the operation of the soil putting apparatus 1, the operation of transferring the pallet B from the soil putting apparatus 1 to the digging apparatus 2 and the operation of the digging apparatus 2. Set to microcomputer
It is controlled by the stored processing procedure.

In the soil filling apparatus, the soil supply unit 10 is started and stopped, the pedestal 20 is positioned in the XY directions, and the supply sensor 18 sequentially monitors the surface height of the soil supplied to the bowl A. In addition, the transfer operation is started when the operation of the earthing machine 1 is completed, and the hole excavator 2 is started when the transfer operation is completed. There is. In addition, the amount of soil to be placed in the pot A (surface height of the soil), the number and arrangement of the pots A (for example, the type of the pallet B to be used, etc.) are set in advance in a microcomputer (not shown), The versatility is enhanced by setting various sizes for each bowl A. Since the control content is almost the same as the operation of the multi-hole forming machine 100, the description of the control means will be substituted in the following operation description.

(Explanation of Operation) (1) Initial Operation First, prior to the operation, the information of the bowl A is set and set in the control means. Specifically, the bowl A to be placed on the table 20
, The number, size, and arrangement are determined and set in the microcomputer. For example, the size of the bowl A may be matched with the commercially available pallet.

After setting, the pallet B in which the empty bowls A are lined up is placed on the Y stand 26 of the placing table 20 in the soil putting apparatus 1, and the pallet B is brought close to the guide plate 28 to be aligned. deep. When ready, turn on the start switch of the multi-hole forming apparatus 100.

(2) When the soil filling device 1 is operated, first, the soil filling device 1 is started, and the first bowl A is positioned below the discharge port 17. Positioning is performed by instructing the X motor 24 and the Y motor 27 at a predetermined rotation speed.

Then, the soil supply unit 10 is started. In the soil supply unit 10, the soil accumulated in the hopper 11 is delivered to the conveyor belt 13 by the two first screws 12 at the bottom of the hopper 11, and is conveyed by the conveyor belt 13 to the position above the adjacent mounting table 20. It is designed to be lifted. The soil in the hopper 11 gradually descends to the bottom due to its own weight. However, in the case of moist soil or clay soil, when the soil is fed out, an arch-shaped cavity is formed around the first screw 12. It is possible for the soil to form and cut off the soil that is coming down. However, at this point, three stirring shafts 5
Since 3 is rotating at a low speed, the cavity can be broken by the rotating claw 54, so that the feeding of soil from the first screw 12 to the conveyor belt 13 can be performed without interruption. Then, the conveyed soil falls from the end of the conveyor belt 13, is collected by the funnel portion 14 provided therebelow, and is poured into the intake port 15 a of the discharge pipe 15. The soil poured into the intake 15a is the second screw 1 of the discharge pipe 15.
It is taken in by 6, but at this time, pebbles mixed with soil,
Even if it is about to be sandwiched between the blade 62 of the second screw 16 and the inner circumference of the intake port 15a, it is escaped by the chamfered portion of the blade 62, and is also escaped by the guide 67 of the rubber plate. The second screw 16 does not stop. The soil taken in this way is the second screw 1
6 is moved in the discharge pipe 15 and continuously and sequentially from the discharge port 17 extended to a fixed position above the mounting table 20.
Is discharged. Therefore, the surface height of the soil supplied to the lower pot A also gradually increases. When the soil in the pot reaches a predetermined height (that is, a predetermined amount), the control means stops the soil supply unit 10 based on the notification from the supply sensor 18.

After stopping, the position of the Y table 26 is instructed so that the next empty bowl will be below the discharge port 17.
When the positioning is completed, the soil supplying unit 10 is instructed to start and the soil is supplied in the same manner as described above. After that, the same processing is repeated for all the pots A, and when the processing is finished, the earthing apparatus 1 is stopped.

In this way, when the operation of the soil depositing apparatus 1 is completed, the pallet B is pulled by a not-shown locking piece and moved along the guide rail 31a of the hole excavating apparatus 2 to notify the stop sensor 31b. Based on this, the pallet B is stopped at a predetermined position on the base 31.

(3) Operation of the digging device 2 Next, the operation of the digging device 2 will be described.

As described above, when the pallet B is stopped at the predetermined position on the base 31, the digging device 2 is started, whereby the drive motor 38 and the lifting motor 36 start operating at the same time. The drive gear 38a on the side of the drive motor 38 installed on the upper surface of the lift table 34 corresponds to the gear 4 on the side of the trench head 40.
5a is engaged, and the plurality of hole excavating bodies 42 are finally driven to rotate via the gear portion 45.

The moat head 40 which is rotationally driven in this manner moves the rack gear 35 downward by the lift motor 36 which has started to operate, and the lift table 3 supported by the rack gear 35.
Start lowering 4. Then, first, the stabilizing plate 46, which is loosely fitted and supported below the base plate 41, moves to the bowl A by its own weight.
Press down from above to prevent the pot A from moving or turning together with the digging body 42 during digging.

Further descending, each hole hole body 42
However, while penetrating the hole 46a of the stabilizer 46 downward, it can be pushed into the pot A containing soil to dig a hole for soil. That is,
Due to the rotation of the soil scraping section 43, the soil scraped in the centrifugal direction is pushed out to the succeeding soil which is successively scraped,
It is pushed upward along the side surface of the pressing portion 44. In other words, while digging a hole in the soil, the walls of the hole are piled up with the soil that has been scraped away, and the wall of the soil hole is appropriately pressed and solidified by the pressing portion 44, so that the soil hole that is hard to collapse It is formed.

When the hole excavation body 42 is pushed to a desired depth, the lift table 34 touches the lower limit switch 39a attached to the support column 32, and the lift table 34 is folded up and raised.
This time, the limit switch 39b at the upper end is touched to stop at a fixed position, and one digging operation is completed.

Hereinafter, the above work may be repeated as many times as necessary.

[0040]

As described above, according to the present invention, since the soil is continuously supplied, it is possible to accurately continue and stop the soil supply to the pot, and Like, letting it fall under the own weight of the soil, like a bucket conveyor,
Since the supply amount does not have abruptness or waves, it is possible to achieve an accurate supply amount for each pot without soil being overfilled and worn out. Moreover, since the soil discharge port is narrower than the opening of the pot, the soil rarely spills out of the pot, and therefore the work of recovering the surplus soil, which occurs in such a case, becomes unnecessary. And the mounting table located below the discharge port
Since a plurality of pots placed on a predetermined arrangement on it are provided with positioning means for positioning them below the discharge port, it is possible to automatically carry out earthing of the plurality of pots when started. Therefore, labor saving and a large amount of soil filling work can be performed.

Since the pots thus soiled can be collectively transferred to the digging device for each pallet, holes for transplantation can be made quickly and in a large amount as never before.
Also, when digging a hole, a soil scraping portion that rotates at the lower end surface of the inverted truncated cone shape to scrape the soil in the centrifugal direction, and the scraped soil is pressed by the side surface of the inverted truncated cone shape to the hole. Since it has a pressing part that forms the side wall of the, it is possible to form a hole in the soil that matches the shape as it was extracted from the pot before transplantation, and in a state where it does not collapse easily, work to cover the soil after transplantation However, it can be largely omitted.

Also, since a plurality of excavated bodies can be exchanged, it is possible to adapt to the size, number and arrangement of the pots.

As described above, according to the invention of the present application, the preparation for transplanting seedlings into a large number of pots can be easily carried out, and the work can be carried out more effectively if the predetermined arrangement is matched with the existing pallet. .
