The post-processing mechanism 6 is supported on the vehicle body or on the driving unit 41 on the vehicle body and the like. The post-processing mechanism 6 simultaneously transports the frame 53 to the rear of the plurality of seedling boxes N in the left-right direction. A vertical transport unit 15 such as a conveyor is provided, and the frame 53 is supported by the height adjusting unit 14. The height adjusting means 14 employs a pantograph type, but other mechanisms may be used. With this height adjusting means 14, the vertical transport means 15 can be adjusted in height while keeping the transport surface substantially horizontal. Rear transport mechanism 3
According to the height change of the rear part, the height of the seedling box N conveyed rearward is adjusted to be easily transferable.

The height of the rear portion of the rear transport mechanism 3 and the height of the post-processing mechanism 6 are determined by artificially removing the seedling box N from the post-processing mechanism 6, so that the height of the worker's waist (generally 60 to 8
The seedling box (0 cm) is set to a height that is easy to handle, and when taken out mechanically, it is adjusted to the carry-in height of the machine. The vertical transport means 15 can place one or a plurality of seedling boxes N in the front-rear direction, and can be constituted by idle rollers. However, in order to place the seedling boxes N more accurately, It is preferable to drive by 56 or use a motor roller, and it is preferable to provide a stopping means 57 at the rear end for preventing the seedling box N from falling off.

The stopping means 57 includes, for example, a plate material 57a
Is configured to be able to move up and down by a solenoid 57b and the like. 13 is a detecting means such as a photo sensor for detecting the presence or absence of a seedling box N on the vertical transport means 15 and a limit switch;
After detecting that the seedling box N has disappeared on the vertical conveying means 15, the next seedling box N is carried in by the rear conveying mechanism 3.

The frame 53 of the post-processing mechanism 6 may be separated and independent from the frame 43, or may be pivotally connected. When the height of the rear end of the rear transport mechanism 3 is adjusted,
It is preferable that the height of the vertical transport means 15 can be adjusted at the same time. The box pick-up mechanism 4 is shown in detail in FIGS. 3 and 4 and is supported by a support frame 61 protruding forward and upward from the frame 43 of the rear transport mechanism 3, and is deployed on the ground at the front side of the rear transport mechanism 3. A plurality of seedling boxes N in the left-right direction can be simultaneously lifted and placed on the rear transport mechanism 3.

The box pick-up mechanism 4 supports a rotating shaft 63 which is rotated by the power of a motor 62 at the front of a supporting frame 61, and a swing arm 64 is attached to the rotating shaft 63, and The hook member 22 is pivotally supported at the tip of the arm 64,
The tip of the hook member 22 is bent into an L-shape so as to be hooked on the flange Na of the seedling box N.
It has become. The motor 62 can rotate forward and reverse and can control the rotation angle.

A forcible detaching member 65 is disposed in front of the entire hanging member 22. Both ends of the forcible detaching member 23 are attached to a gear 66 which is supported by the support frame 61.
The gear 66 meshes with a gear 67 provided on the rotation shaft 63, so that the forcible detaching member 65 can swing in a direction opposite to the rotation direction of the rotation shaft 63. The forcible detachment member 65
And the pair of gears 66, 67, etc., constitute the forced release means 23.

As the moving vehicle 2 advances, the hooking claw 22a at the tip thereof comes into sliding contact with the ground, and the hooking claw 22a
When the child further advances from the state in which it comes into contact with the seedling box N, the lower end circularly moves rearward and upward about the upper end thereof. The circular movement of the hook member 22 raises the rear part around the seedling box N at the front end, and the front part of the rear transport mechanism 3 that has been advanced is inserted under the raised seedling box N.

The motor 62 operates to swing the rocking arm 64 forward before and after the hanging member 22 starts lifting the seedling box N, or from the latter half of lifting, so that the lifting height of the seedling box N is increased. When the forcible detachment member 65 is swung rearward, when the rear portion of the seedling box N reaches above the rear transport mechanism 3, it comes into contact with the middle portion of the hooking member 22 and forcibly jumps up rearward, The hook 22a is detached from the seedling box N.

When the hook 22 is released, the seedling box N is transferred to the rear transport mechanism 3, and is transported to the post-processing mechanism 6 by the rear transport of the rear transport mechanism 3. The seedling box N placed on the post-processing mechanism 6 is artificially taken out by an operator and placed on a stack such as a shipping shelf or a shelf unit. Thereafter, the motor 62 is rotated in the reverse direction to return the latch member 22 to the original position.

When the height of the post-processing mechanism 6 is not suitable for the worker, the height of the rear portion is adjusted by changing the inclination angle of the rear transport mechanism 3 and the height adjusting means 14 is used accordingly. Then, the height of the post-processing mechanism 6 is changed to match the height of the rear transport mechanism 3. The hanging member 22 may be provided with two hanging claws 22a below one bar for one seedling box N, but a plurality of L-shaped rods at the tip may be used.

The seedling box detection means 24 is composed of a photosensor or the like which is attached to the left and right ends of the support frame 61 via support rods 70 so as to be adjustable in height, and detects the presence or absence of the seedling box N by reaching the side thereof. Then, after a set time, the motor 62 is rotated forward by a predetermined angle.

The seedling box detecting means 24 may detect the seedling box N which has been lifted to a position above the rear transport mechanism 3 by the hooking member 22, or a fixed time after a set time from the detection of the seedling box N. The rear transport mechanism 3 may be operated only during the period. In the box picking-up mechanism 4, since the hooking member 22 is pulled up by the swing arm 64, the component force for pushing the seedling box N forward can be reduced, and the lifting force can be increased. Since the pulling-up of the seedling box 22 can be performed and the forced detachment state can be maintained, the latching member 22 is held upward until the substantially entire length of the seedling box N is transferred to the rear transport mechanism 3. Can be kept.

In the first embodiment, the seedling box collecting machine A
1 is moved at a constant low speed, picked up by the box pick-up mechanism 4 while detecting the seedling box N deployed on the ground, and transferred to the rear transport mechanism 3. After being transported backward, the rear transport mechanism 3 is transferred to the vertical transport means 15 of the post-processing mechanism 6, and the worker picks up the seedling box N from the vertical transport means 15. A self-propelled vehicle such as a light truck accompanies the seedling box collection machine A1, or a stock trolley is pulled behind the seedling box collection machine A1, and a stacked body capable of storing the seedling boxes N in multiple stages is mounted thereon.

In addition, the transport of the seedling boxes N can be individually controlled.

Power is transmitted from one motor 48 to the transmissions 71A, 11B, 11C via a transmission shaft or a winding transmission means, and this power is transmitted to the conveyor means in each drive area 11. The power to each drive area 11 can be individually connected and disconnected by 71A, 11B and 11C. At the rear end of each of the drive areas 11A, 11B, 11C, a stop means 12 for restricting the transfer of the seedling box N is provided, and when the seedling box N is clogged in the subsequent drive area 11, the stop means 12 is activated. By disengaging the clutch of the transmission unit 71, the seedling box N being conveyed can be stopped and the conveyance temporarily stopped in the drive area 11 of the previous stage, and the front side can be stopped when the seedling box N of the latter stage is stopped. To prevent falling.

Thus, the seedling boxes N picked up by a single worker can be stocked in the middle, and the seedling boxes N in one row can be stocked.
Can be corrected even if they are not aligned. When the former stage becomes empty, the box pick-up mechanism 4 is operated to start the seedling box N collection operation.
Boxes can be picked up until all stages are clogged, reducing loss time. Also, adjust the front and rear spacing of the seedling box N,
The transport speed can be changed.

The post-processing mechanism 6 pivotally supports the flat plate member 72 or the free roller conveyor to the frame 43 of the rear transport mechanism 3 via a pivot 73, and an arc member 74 on the post-processing mechanism 6 side.
Is fixed to a bracket 75 fixed to the frame 43 side so that the angle can be freely changed, and the seedling box N conveyed by the conveyance force of the rear conveyance mechanism 3 can be placed substantially horizontally. When the angle of the rear transport mechanism 3 is changed to change the rear height, the rear processing mechanism 6
Can be corrected so that the post-processing mechanism 6 becomes horizontal.

The drive area 11 may be provided with a separate motor instead of the transmission section 71 provided with a clutch. The stopping means 12 is formed of a solenoid or the like and individually stops the seedling boxes N. However, a member that is long in the left-right direction may be used so as to stop the seedling boxes N in one horizontal row at the same time, and may have a configuration similar to, for example, the stopping means 57 shown in the first embodiment. A stopping means 57 may be provided at the rear, and a detecting means for detecting the presence or absence of a seedling box N on each of the driving areas 11A, 11B, 11C is provided, and automatic control is performed together with the stopping means 12.

It can be pushed and moved to the transfer table 79 by 1a. After the seedling box N is moved to one of the left and right ends by the lateral transport means 16, the seedling box N is moved backward by the claw conveyor 81, and this operation is sequentially repeated, so that the seedling box N can be artificially taken out from the delivery table 79. It is preferable that the delivery table 79 is also provided with a detection means 13 for detecting the presence or absence of the seedling box N, and when the seedling box N is exhausted, the horizontal conveying means 16 and the claw conveyor 81 are preferably operated.

Since the lateral position of the auxiliary transport means 17 can be freely changed, it is possible to select a position where the worker can easily work, and which position of the seedling box N on the post-processing mechanism 6 in the lateral direction. However, if the right and left positions of the seedling box N can be detected by the detecting means, the lateral transport means 16 can be taken out.
