Description

[Detailed Description of the Invention] Industrial Field of Application This invention provides a method for forming a pot group in which the upper edges of each seedling-growing pot are connected to each other and the lower sides thereof are independent, forming a rectangular pot group as a whole. Place a paper or resin seedling container with sprouting holes on top of the board container, and assemble it.
While this container-assembled seedling raising device is being transported by a conveyor, a small amount of covering soil is supplied into each pot by a soil-covering supply device, then seeds are sown by a seeding device, and then bed soil is supplied by a bed-soil supply device and then transported. A seedling box feeding device is installed to cover the seedling box with a seedling box from above after the seedlings are sown and the bed is filled with soil. The present invention relates to a seedling transfer type seeding device in which the upper surface of the container is removed and then watered.

Prior Art Conventional reversing devices do not have a fully automatic reversing device, and instead fit the receiver assembly/i'1 container covered with the transferred seedling box into a biting frame that is U-shaped when viewed from the side. It was designed to be swung 180 degrees.

Problems to be Solved by the Invention Conventionally, only the end side in the transfer direction of the transferred receiver-assembled seedling grower was held and reversed, so the receiver and the seedling grower or the seedling box and the seedling grower were separated. Not only did the gap between the pot and the pot open during the inversion, causing the soil in the pot to leak out, but the inversion device was not fully automatic, resulting in poor work efficiency and the need for manual labor.

Means for Solving the Problem The upper edges of the seedling growing pots 9a are connected to each other and the lower sides are independent, forming a rectangular pot group as a whole, and
A paper or resin seedling grower 9 with a sprouting hole 9b drilled in the bottom of each pot is placed on the top of a plate receiver 10 and assembled.
While this container-assembled seedling raising device P is being transported by a conveyor, a small amount of covering soil is supplied into each pot 9a by a covering soil supply device C,
Subsequently, the seedlings are sown with the seeding device, and then the bedding soil is supplied with the bedding soil supplying device E and the seedlings are transferred.After sowing, the seedling box 18 is appropriately covered with the seedling box 18 of the seedling growing device P with a receiver assembly, and the seedlings are transferred. In a seeding machine for a pot-shaped seedling nursery device, a reversing device H is provided to turn the container upside down, and the receptacle is removed and watered after being turned upside down by the reversing device H. A clamping device is provided for clamping the receiver-assembled seedling raising device P on which the seedling box 18 is covered from the upper and lower surfaces of an intermittent co-rotating body that penetrates in the front-rear direction and stops rotating every 180 degrees around the core. A seedling raising device pulling device is provided on the front side of the intermittent co-rotating body to forcefully push the seedling raising device P with a receiver assembly between the upper and lower clamping devices of the intermittent co-rotating body, and a This reversing device in a seeding machine for a pot-type seedling nursery is provided with a seedling raising device pulling device J for forcibly pulling out a seedling growing device P which is held between upper and lower holding devices of an intermittent co-rotating body and turned upside down.

Functions and Effects of the Invention Since the present invention has the above-described configuration, the receiver-assembled seedling raising device P covered with the seedling box 18 is placed between the intermittent co-rotating body clamping devices (between the rollers 33a, 33b and 34a, 34b). When it is pushed in by the pushing device I and then forcibly pushed in on the transfer tip side of the subsequent receiver-assembled raised seedlings WP, the rotating body rotates 180 degrees at a certain position during the pushing. And 1
When it is stopped after rotating 80 degrees, the succeeding receiver-assembled seedling-raising device P pushes the inverted receiver-assembled seedling-raising device P in the transfer direction side again, and this pushed-out receiver-assembled seedling-raising device P is pulled out. It is pulled out by device J and transported as it is. therefore,
According to this invention, a special transfer device is not required for the intermittent co-rotating body of the reversing mechanism itself, the structure is simple, and the seedling raising device P with a receiver assembly can be accurately reversed during the transfer of the seeding device. It has the effect of being able to.

A scooping rod 72 for scooping up the lower surfaces of the left and right flanges 10c of the receiver 10 located on the upper surface of the seedling nursery P which is transferred by the conveyor while being inverted by the reversing device H is pivotally connected to the frame 1 with a pin 74. , the rear end of this scooping rod 72 is attached to the scooping rod 72.
A receiving rod 73 is pivotally connected so as to be rotatable only downwardly from a straight line that does not protrude upward from the extension surface of the upper surface of 2, and the receiving rod 73
is supported on the frame 1 by a support 75, and the receiving rod 73 is in a substantially horizontal state and the scooping rod 72 is inclined. Then, this receiving rod 73 is rotated up and down by a reciprocating arm 78 operated by a crank pin 77 that is transmitted and rotated by a one-rotation fixed position stop clutch mechanism 76, and the scooped up receiving container 10 is lifted up and down at once. It is designed to slide down.

To explain the transmission structure specifically, a clutch cam body 79 having a large number of clutch pawl engagement recesses 79a formed on the inner peripheral surface is fixed to a rotating shaft 78 installed on the frame 1 so as to be transmitted and rotated. Rotation III! is attached to the rotating shaft 78 via a one-way transmission mechanism 80 so as to be rotatable in the direction of rotation of the shaft but not in the opposite direction. 81 has a protrusion 8

The rotating shaft 81 is configured to be rotated by transmission. Then, a crank pin 77 is implanted in the rotating shaft 81, and an arm 85 rotatably mounted on the front frame 1 is connected via a long hole, and a support shaft 86 integrated with the arm 85 is connected to the Install arm 78,
A long hole 88 is bored at the tip of this arm 78, and a pin 89 installed in the receiving rod 73 is inserted therethrough.

The above-mentioned clutch "on" and "disengagement" operations are performed by the clutch operating pin 9o that comes into contact with the protrusion 82a of the clutch pawl 82, and when this pin 90 comes into contact with the protrusion 82a, the clutch pawl 82 receives the rotational force of the rotating shaft 81, rotates inward against the spring 84, and engages the engagement recess 79.
The rotating shaft 81 stops when it comes off from the protrusion 82a, and the power is transmitted when it comes off the protrusion 82a.

This clutch actuation pin 90 is connected to a piston 92 that retracts when a solenoid 91 is energized and protrudes when it is not energized.
The solenoid 91 is energized by a switch SW4 which is provided on a conveyor section after the receiver removing device and detects the seedling boxes 18 being transferred, and is deenergized by a switch SW2. The pin 90 is configured to be instantaneously reciprocated when the seedling box 18 is detected, and the clutch is "disengaged" every rotation.

Reference numeral 94 denotes a return conveyor, the starting end of which is connected to the sliding support rod 93, and returns the receiver 10 to the starting end side of the seeding device.

L is the master conveyor, and A is the fourth conveyor.

A device is provided on the conveyor belt 7 for supplying soil approximately 8 minutes between each pot of the inverted seedling raising device 9, and is composed of a soil storage tank 95 and a soil feeding device 96. There is.

Reference numeral M denotes a watering device, which is located at the rear of the above-mentioned nurturing device J, and is a device for irrigating the surface of the seedling growing device 9, and has a fountain nozzle 97 attached to a water pipe.

In addition, the symbol 98 in the figure is a rod to prevent the seedling box from slipping off, which is installed at the bottom of the reversing device H, and prevents the seedling box covered with the seedling box being inverted from accidentally slipping off from the clamping device during reversing. It is a guide rod.

To explain the operation of the upper side, first, the receiver 10 is placed on the lower surface of the seedling grower 9 and the assembled seedling raiser P is transferred to the first conveyor 1 conveyor belt 3 of construction A by the seedling raiser supply device B. When the seedlings are placed on top and fed, a small amount of covering soil is transferred and put into each pot 9a of the seedling raising device 9 being transferred by the covering soil supply device C, and then seeds (seed rice) are placed in each pot 9a by the sowing device. The soil is poured onto the covering soil and sown, and then the bed soil is supplied into each pot by the bed soil supply device E, and the full bed soil is leveled by the compaction device F and pushed into the pot 9a to be used in the seedling raising device. It is sent below the laying down device 111G.

At this time, the detector 27 detects the state in which the receiver 10 has passed because the receiver-assembled seedling-raiser P is not present at the lower transfer end side of the lower part of the seedling-raiser lowering device G. A signal is emitted to energize the electromagnetic solenoid 20, and the seedlings χc at the bottom stacked face down on the rolling roller 19, 19 as a front support and the pin 21a as a rear support are
At the same time as the pin 21a is retracted to supply the seedling box 118, the pin 21b is protruded to temporarily support the second seedling box 18 from the bottom so that it does not fall together, and then the pin 21a in its original state is protruded. Operate. In addition, the next detector 27
In this detection, a signal is emitted when the seedling raising device P with a receiver assembly passes through this detection section.

Therefore, only the side of the seedling box 18 in the transport direction falls onto the conveyor, and the rear part is supported by the rollers 19, 19.

Then, when the seedling raising device P with the receiver assembly is sent, the front end of the seedling raising device 9 fits into the lower end of the seedling box 18 in an inclined position and is transferred, and then the pressure roller 22 He is being sent away while being held down.

When the rear support of the seedling box 18 comes off from the rear rolling roller 19, it is held down by the pressure roller 22.
- At the same time, the seedling box 18 securely fits into the seedling raising device 9.

The seedling raising device P covered with the seedling box 18 and sent out from the seedling raising device lowering device G in this way is forcibly moved by the upper and lower holding rollers 2 of the reversing device H by the seedling raising device pulling device.
9a, 29b and 30a.

30b as shown in Figure 15. Then, when the seedling box 18 is slightly removed from the reversing device i7H, the tip surface hits the sensing roller 66 of the detector 59,
This roller 66 is moved rearward. Then, the clutch actuating rod 68 connected thereto moves rearward and disengages from the projections 51a and 52a of the clutch pawl 51 or 52 of the half-rotation fixed position stop clutch mechanism 46, and the clutch pawl engages the clutch cam body 54. The shaft body 48 engages with the engagement recess opening.
is rotated, and the drive shaft 34 is transmitted.

Therefore, the left and right plates 28a and 28b are rotated by transmission, and the seedling raising device P with a receiver assembly, which is held between these plates, is moved to the first
After going through the state shown in Figure 6, it is turned upside down. In this case, when the seedling raising device P to be reversed is rotated with the rotation axis of the reversing device H as a reference, at the start of reversing, the seedling raising device P is rotated with a deviation to the front side, and after being reversed, as shown in FIG. deviates to the rear.

Then, after the reversal starts, the seedling raising device P that had been in contact with the sensing roller 66 is removed from the roller 66, so that the spring 70 causes the clutch actuating rod 68 to return to its original state together with the roller 66 (hereinafter referred to as a blank). Therefore, the protrusions 51a and 52b of the clutch pawl 51.52 come into contact with the clutch actuating shaft 68 during half a rotation, and this contact causes both the clutch pawls 51.52 to disengage from the engagement recess opening and the clutch to be "disengaged". become. For this reason, the drive shaft 34
The rotation of the motor is stopped in the state shown in FIG. 17. That is,
After being reversed, the seedling raising device P is largely deviated from the center of the rotating shaft to the rear side and stopped, resulting in the state shown in FIG. 17.

At this time, the sensing roller 66 as the detector 59 is pressed downward by the inverted seedling box 18 and pushed downward against the spring 71, so that it does not become a transfer resistance.

During the inversion of the growth device, the support shaft 33 and the frame t
Since the one-way transmission mechanism 35 is provided between the seedling raising device and the seedling raising device, it does not turn over under its own weight even if it passes the upright state in the middle of reversing, and the support shaft 34 and clutch cam body 54
Since a one-way transmission mechanism 55 is also provided between the seedling raising device and the seedling raising device, the seedling raising device does not vibrate due to rattling caused by a chino transmission or the like, and can be turned over stably.

In this way, when the seedling raising device P2 is reversed, the rear end of the seedling raising device P1 after being reversed is because the previous seedling raising device P which was reversed was rotated in a state closer to the front from the center of rotation. During this time, the subsequent seedling raising device P2 can be continuously transferred without stopping the transfer, and efficiency is not reduced.

Then, the seedling raising device P□ after inversion is stopped in the state shown in Figure 17, but at this time, the tip of the succeeding seedling raising device P2 pushes the stopped seedling raising device P1 from behind and transfers it to the front. The container P1 is the clamping roller 38a, 38 of the seedling raising device pulling device J.
b, 39a, and 39b, and is transported while being pulled out backwards.

In this case, the drawer transfer speed v2 of the drawer [J is set to be high compared to the feed transfer speed V□ by the pushing device, and the distance l between the seedling raising device P2 that follows is made equal to the transfer speed. . This transmission configuration is shown in Figs. 19 and 2.
Consisting of sprockets a, b, c, and d shown in Figure 0 and a chino that transmits power between them, the pitch circle size of these sprockets is set to d>a>b=c, and the transfer speed of the drawing device J is The operating rotational speed of the receiver removing device and its transfer speed V are set higher than v2, and the subsequent transfer speed of the conveyor belt 7 is made lower, so that in the subsequent transfer to this receiver removing device, the speed of the pushing device 1 is The transfer speed is returned to V□, and the seedling raising device is transferred with no gap between the front and back, so that the soil supplied by the soil filling device iL does not spill downward.

Although the explanation has been repeated, when the above-mentioned inverted seedling raising container P is pulled out and transferred by the pull-out device J, the container removing device K removes the container 10 located at the upper part by the scooping rod 72. The left and right brim 10c portions are scooped out and gradually pushed upward.

When the rear side becomes heavier, the receiver 10 rotates and rests on the receiver rod 73, and is reliably removed upward from the seedling growing pot 9. On the other hand, the seedling boxes 1 to 9 placed in the seedling box 18 from which the receiver 10 has been removed are transferred to the rear, and are transferred to the rear by the switch SW.
is detected and the solenoid 91 is energized.

The one-rotation fixed-position stop clutch mechanism 76 is turned on, the rotating shaft 78a is rotated, the one-rotation transfer 81 is rotated, and the arm 78 is reciprocated up and down via the arm 85 by its crank pin 77. For this reason, as shown in Figure 13, the receiver 7
3 is swung up and tilts greatly in a straight line together with the scooping rod 72.

Therefore, the receiver 10 placed on the receiver rod 73 quickly slides down and falls forward and downward from between the transfer rollers of the conveyor. Then, it is received by the sliding support rod 93 and slides forward. Thereafter, it is transferred to the starting end side of the seeding device by a conveyor 94.

Furthermore, after the switch SW1 is turned on and the solenoid 91 is energized, the solenoid 91 is immediately de-energized by the subsequent switch SW2, and the operating pin 90 returns to its original position. When it rotates, it comes into contact with the operating pin 90 and the clutch is disengaged. Therefore, the receiver rod 73 returns from the tilted state and maintains the solid line state shown in FIG. 13, and becomes ready to start removing the subsequent receiver 10.

Next, when the seedling raising container 9 from which the receiver 10 has been removed is transferred to the soil filling device J, soil is poured into each pot 98 for about 8 minutes, and then the irrigation device is filled with soil. Irrigated.

In this way, a series of seeding operations is completed.

In the above-described embodiment, the seedling raising device laying down device G is incorporated in the process of the seeding machine, but this device G may be made removable so that this process can be performed manually.
