Abstract

PURPOSE:To automatically transfer seedling growing cases, when placed in n layers, to a moving station, by providing a stacking apparatus with sensors for detecting (n-1)th and n-th layers of the seedling growing cases and connecting the above two sensors to a moving device. CONSTITUTION:When a preceding seedling growing case 7 reaches the taking-out side 6 of a transfer table 1, it is laid on a support frame 44 by a quick traverse roll 54. When the front end of the seedling growing case 7 comes in abutment against a sensor 81, chains 34, 35 are rotated to lower the support frame 44, and the support frame 44 goes away upwardly, leaving the seedling growing case on receiving rings 23. Another support frame comes to the position for receiving a next seedling growing case 7. The operation is repeated (n-1) times, and when (n-1) layers are stacked, the (n-1)th seedling growing case holds a sensor 87 on, and when n layers are stacked, a sensor 88 is held on, and on state of the sensors causes the receiving rings 23 to rotate, so that the cases placed in layers are transferred to a moving station 82.

When the tip 80 of the seedling-raising box 7 reaches the fast-forwarding roll 54, it is fast-forwarded and supplied onto the right receiving frame 44 and the left receiving frame 45, but the timing at which the rear end 79 of the seedling-raising box 7 leaves the fast-forwarding roll 49 is determined. A sensor 81 with which the front end 80 comes into contact is provided in front of the frame columns 24 and 26.

The sensor 81 is linked to a solenoid 68, and when the sensor 81 is pressed by the front end 80 of the seedling box 7, the solenoid 68 is energized, the clutch 67 is engaged, the rotating shaft 62 is rotated, and the bevel gears 63, 64 and 65 are connected. ．．
The rotating shaft 29 and the rotating shaft 37 are rotated through the rotating shaft 66, so that the rotating shaft 29 and the rotating shaft 37 are
is rotated to lower the seedling raising box 7.

Both the right receiving frame 44 and the left receiving frame 45 are attached to the chain 7 in such a manner that they cannot be rotated downwardly but can be rotated upwardly.

The right receiving frame 44 and the left receiving frame 45 are used to stack the seedling boxes 7 one by one, and when n sheets are stacked, they cannot be stacked any more, so they are moved horizontally. A sensor will be installed to detect the buildup. The sensor consists of a sensor 87 that detects up to n-1 and a sensor 88 that detects the n-th image, and is attached to a mounting rod 89, and
When n seedling boxes 7 are piled up on the receiving ring 23 of No. 2, they are transported laterally and transferred. 83 is a driving wheel, 84 is an intermediate wheel, 85
is a switch.

(effect) Next, we will discuss the effect.

When the seedling boxes 7 are supplied one after another onto the supply side 5, they are transferred by the transfer rolls 4, and as they pass below the above-floor supply device 8, the beds ±13 in the hopper 11 are supplied by the rotation of the feed rolls 12, and the bed soil is The floor ±13 is leveled by the leveling brush 14, and when it reaches the bottom of the seeding device 9, the seeds in the hopper 15 are supplied by the feed roll 16, and after being irrigated by the irrigation device, they reach the bottom of the soil-covering device 10. Then, the feeding belt 2
The covering soil 21 in the hopper 19 is supplied by the rotation of 0, and sowing is completed. are continuously fed in contact with each other, but when the front end 80 of the seedling raising box 7 reaches the fast feed roll 54, the fast feed roll 54 is rotating faster than the transfer roll 4, so the part indicated by arrow a It separates and moves forward by sliding on the right receiving frame 44 and left receiving frame 45, and its front end 80 collides with the sensor 81 and stops, and the rear end 79 of the seedling nursery box 7 passes the rapid transport roll 49 and moves forward with the right receiving frame 44. Move onto the left receiving frame 45.

Since the sensor 81 is linked to the solenoid 68, the solenoid 68 is energized and the clutch 67 is connected via the rod 69.
combine. Then, the rotation of the motor 59 is as follows: drive shaft 60 → sprocket 61 → chain 78 → sprocket 70 → rotating shaft 62 → bevel gear 63 → bevel gear 6
4→rotating shaft 29 and bevel gear 65→bevel gear 66→lower rotating shaft 37, and the transmission is as follows: chain 734, chain 735, chain 742, car y43+@movement gear. A. Right receiving frame. 1) 4 and the left receiving frame 45 move down with the seedling raising box 7 placed thereon, and the seedling raising box 7 finally reaches above the retaining ring 23.

At this time, the right receiving frame 44 and the left receiving frame 45 are also receiving rings.

23, but since both are attached to a structure that is fixed downwards and rotates freely upwards, like the lifting lug of a combine harvester, the right receiving frame 44 and the left receiving frame 45 escape upward, and therefore smoothly move. Rotate.

When the right receiving frame 44 and the left receiving frame 45 rotate 1800 times, they collide with the switch 86, so the solenoid 68 is de-energized and the clutch 67 is disengaged.
5. The rotation of the chain 42 and chain 743 is stopped.

At this time, another right receiving frame 44 and a left receiving frame 45 are replaced, and the seedling raising box 7 is ready to be placed therein.

If such an operation is repeated about n-1 times, n-1 seedling boxes 7 will be stacked on the retaining ring 23, and each time the seedling box 7 is lowered, it will pass in front of the senners 87 and 88. ,n
- When one seedling box 7 is stacked, the sensor 87 is turned on at the (n-1)th seedling box 7, and when n sheets are stacked, the sensor 88 is turned on at the nth seedling box 7. When the sensor 87 and 88 turn ON, the solenoid 74 is energized, the clutch 72 is engaged, and the shaft 71 is rotated, thereby rotating the retaining ring 23 to move the stacked side transfer portion 582. It will be relocated.

The front end 80 of the seedling box 7 that has been transferred to the transfer section 82 is the switch 8.
5, the solenoid 74 is cut off and stops.

(Effects) As described above, in the seedling box seeding device that supplies soil on the bed and in seeds, the seedling boxes that are continuously transferred are manually taken out one by one at the end of the transfer table.

However, the conventional device requires two or three people to take out the seedling boxes that are successively transferred to the take-out side of the seedling seeding device and transport them to a predetermined location one after another.

However, in the present invention, the seedling raising box 7 sent out from the transfer stand 1 is moved to an extension of the take-out side 6 of the transfer stand 1, which has a device for supplying all or part of the bed, seeds, covering soil, etc. to the seedling raising box 7. A stacking device for stacking the seedling boxes 7 is provided, and a transfer section 82 for the n-stacked seedling boxes 7 is provided in the extension of the stacking device, so that even if the seedling boxes 7 are fed one after another to the transfer table 1, they will not be transferred to the take-out side 6. Because it is stacked,
Even if only a small number of people are present on the take-out side 6, the seedling growing box 7 can be supplied to the transfer table 1.

Further, the stacking device is provided with a sensor 87 for detecting the n-1th seedling seedling box 7 and a sensor 88 for detecting the nth seedling box 7, and the sensors 87 and 88 are connected to the transfer device to operate the stacking device. When n seedling boxes 7 are stacked, the transfer unit 82 automatically
If this operation is repeated about n-1 times, n-1 seedling boxes 7 will be stacked on the retaining ring 23, and each time the seedling box 7 is lowered, the sensors 87 and 88 will be activated.
However, when n-1 sheets are stacked,
The sensor 87 is turned ON, and when n sheets are stacked, the sensor 88 is turned ON, and when both sensors 87 and 88 are turned ON, the trenoid 74 is energized and the clutch 72 is engaged. Since the shaft 71 is rotated, the retaining ring 23 is rotated, and the retaining ring 23 is moved to the stacked side transfer section 82, the two sensors can be skillfully used to ensure reliable operation.
