As shown in fig. 11, when the plant-loaded tray 7 advances to the intersection of the fourth conveyor belt 4 and the second conveyor belt 2, since the fourth conveyor belt 4 and the second conveyor belt 2 are arranged perpendicular to each other, and the direction of transport of the fourth conveyor belt 4 and the second conveyor belt 2 is also perpendicular, the pallet 7, when passing the intersection point, since the front end of the tray 7 enters the second conveyor belt 2 first, the second conveyor belt 2 drives the front end of the tray 7 to advance in the conveying direction thereof, thereby driving the tray 7 to turn, since the rear end of the pallet 7 is also pushed, the pallet 7 is gradually pushed by the fourth conveyor belt 4 to the second conveyor belt 2, the second conveyor belt 2 turns the pallet 7, so that the pallet 7 can be diverted to the second conveyor belt 2 and continue to move on the second conveyor belt 2. The fourth conveyer belt 4 is further provided with a photoelectric sensor at the tail end thereof, the second conveyer belt 2 is further provided with a proximity sensor at the edge corresponding to the advancing direction of the fourth conveyer belt 4 and far away from the fourth conveyer belt 4, when the tray 7 is turning, the photoelectric switch is firstly touched to turn on the proximity sensor, when the tray 7 is too close to the proximity sensor, the tray 7 is judged to be about to fall off the second conveyer belt 2, at this time, the operation of the second conveyer belt 2 is stopped, and a signal can be sent to a user.

As shown in fig. 8-10, the tray 7 loaded with plants advances on the second conveyor belt 2, the tray 7 needs to enter the first conveyor belt 1 because the second conveyor belt 2 is perpendicular to the first conveyor belt 1, and because the second conveyor belt 2 is used to communicate with a plurality of first conveyor belts 1, the steering device 6 is disposed between the first conveyor belt 1 and the second conveyor belt 2, the steering device 6 includes a steering power member 61 fixed on one side of the first conveyor belt 1, and the steering power member 61 may be a telescopic long arm, in this embodiment, the steering power member 61 uses a cylinder, and in some simple alternatives, other powers, such as a motor, etc., may be used. The end of the power steering element 61 is further provided with a bent arm 62, the bent arm 62 is shaped and configured to fit the peripheral wall of the accommodating portion 71 of the pallet 7, the power steering element 61 can drive the bent arm 62 to move against the direction of the first conveyor belt 1, when the pallets 7 approach, the accommodating portion 71 abuts against the bent arm 62, and then the pallet 7 is pulled toward the first conveyor belt 1. The steering device 6 further includes an auxiliary steering member 63 disposed at the other side of the first conveying belt 1, in this embodiment, the auxiliary steering member 63 is a cylindrical convex pillar protruding upward. When the tray 7 is pulled from the second conveyor belt 2 towards the first conveyor belt 1, until the guide turn 722 of the tray 7 abuts against the auxiliary turn 63, the tray 7 pivots about the auxiliary turn 63 as a pivot point until the bent arm 62 pulls the tray 7 completely into the first conveyor belt 1.

The steering device 6 further includes a distance sensor provided on the second conveyor belt 2, and when the pallet 7 approaches, the steering power unit 61 may advance the bent arm 62 to wait for the pallet 7 to abut against the bent arm 62. In order to prevent the situation that the steering power member 61 cannot extend the bent arm 62 in time due to insufficient power or other reasons, and the bent arm 62 may collide with the tray 7, so that the bent arm 62 is damaged or the tray 7 is pushed out of the second conveyor belt 2, the steering device 6 further includes an anti-collision sensor which can prejudge whether the bent arm 62 can extend in time, wherein the anti-collision sensor may be a proximity sensor arranged at an end of the bent arm 62, and when the proximity sensor is too close, the bent arm 62 is retracted in time. The anti-collision sensor may also be a photoelectric sensor disposed on the steering power member 61, and when the steering power member 61 is started, and the steering power member does not completely extend within a predetermined time, it is determined that a collision occurs, and then the curved arm 62 is retracted in time, but of course, the anti-collision sensor may also be a pressure sensor disposed on the curved arm 62, and when a pressure signal is sensed by the pressure sensor during a collision, it is determined that a collision occurs, and then the curved arm 62 is retracted in time.

The pallet 7 on the second conveyor belt 2 may not be diverted onto the first conveyor belt 1 by the diverting means 6, at which point the pallet 7 may move all the way along the second conveyor belt 2 until it falls off the ground. In order to prevent this, the second conveyor belt 2 is further provided with a touch switch at the end in the traveling direction, and when the tray 7 touches the touch switch, the operation of the second conveyor belt 2 is stopped.

In the prior art, when the tray 7 is diverted to the first conveyor 1, the plants are cultivated under predetermined conditions because the first conveyor 1 is used as a waiting area. When the tray 7 is on the first conveyor belt 1, if the first conveyor belt 1 keeps running, a stop plate needs to be arranged at the tail end of the first conveyor belt 1 in the advancing direction, so that the tray 7 can stop moving only by abutting against the stop plate, and when a plurality of trays 7 enter the first conveyor belt 1, when the first tray 7 abuts against the stop plate, the second tray 7 needs to move all the way to abut against the first tray 7 to stop moving on the moving first conveyor belt 1. During this process, the first conveyor belt 1 will always rub against the bottom of the first pallet 7. In the case of a stop of a tray 7 already present on the first conveyor belt 1, each subsequent entry of one of said trays 7 causes the first conveyor belt 1 to rub against the already stopped tray 7, which causes a greater wear on said first conveyor belt 1 and a greater consumption of energy.

As shown in fig. 12 to 13, in order to solve the problem of the wear of the first conveyor belt 1, the first conveyor belt 1 is configured such that the drive motor 11 of the first conveyor belt 1 runs a distance of one tray 7 length only when entering one tray 7. In this embodiment, a sensing switch 12 is disposed adjacent to the entrance of the first conveyor belt 1, and when the sensing switch 12 senses that the tray 7 enters, the sensing switch transmits a signal to a driving motor 11 of the first conveyor belt 1, and the driving motor 11 travels a stroke of one tray 7 length. The first conveyor belt 1 can thus be moved one stroke per further pallet 7 until the first conveyor belt 1 is full. The first conveyor belt 1 further has an auxiliary sensing switch 13 at an end of the first conveyor belt 1 in the traveling direction, and when the tray 7 touches the auxiliary sensing switch 13, the first conveyor belt 1 stops operating and the second conveyor belt 2 conveys the tray 7 to the other first conveyor belts 1.

When the tray 7 on the first conveyor belt 1 needs to travel to the third conveyor belt 3, the tray 7 is diverted from the fourth conveyor belt 4 to the second conveyor belt 2 in the same manner, and therefore, the description thereof is omitted here.

When the tray 7 on the third conveyor belt 3 needs to travel to the fourth conveyor belt 4, the manner of the tray 7 is the same as the manner of the tray 7 turning from the second conveyor belt 2 to the first conveyor belt 1, and therefore, the description thereof is omitted.

When none of the trays 7 is loaded into the waiting area, the conventional loading method is to load the trays 7 onto the first conveyor belt 1 of the waiting area one by one, which is time-consuming and labor-consuming. In order to solve such a problem, as shown in fig. 2, a placement point 41 is provided on the fourth conveyor belt 4 and in proximity to the second conveyor belt 2, and the placement point 41 is provided with a reader corresponding to the article recognition device 73 on the tray 7. The user may place the tray 7 with the article recognition device 73, to which information has been previously input, on the placing point 41, and the reader determines the information of the tray 7. So that a user can place a plurality of the trays 7 on one placing point 41 and the trays 7 re-enter the second conveyor belt 2 and the first conveyor belt 1.

Referring to fig. 2, the fourth conveyor belt 4 is further provided with two weighing devices 8 and a section of irrigation area 9 between the placing point 41 and the imaging scanning unit 5, and the irrigation area 9 is arranged between the two weighing devices 8. The weighing device 8 may be a multiple chain conveyor belt continuing on the fourth conveyor belt 4 and a lifting device provided on the travel path of the multiple chain conveyor belt, which lacks a rotating component of the rotating lifting device, unlike the rotating lifting device provided in the imaging scanner unit 5, and on which a pressure sensor is further provided to weigh the tray 7 when the tray 7 is lifted. When the tray 7 comes out from the imaging scanning unit 5, the tray firstly passes through one weighing device 8 and then enters the irrigation area 9, and after the irrigation operation is carried out, the tray passes through the other weighing device 8, and the difference value of the two weighing values is compared, so that the irrigation water quantity can be obtained.

The above, only be the preferred embodiment of the present invention, but the design concept of the present invention is not limited to this, and any skilled person familiar with the technical field is in the technical scope disclosed in the present invention, and it is right to utilize this concept to perform insubstantial changes to the present invention, all belong to the act of infringing the protection scope of the present invention.
