Abstract: Abstract: On the basis of the automated guided vehicle (AGV) system, a set of high throughput conveyor system of potted rice was designed in this study to solve the problem that the potted rice should be moved frequently in the cultivation area. The high throughput conveyor system of potted rice can not only realize the automatic conveying in the whole period of cultivation of potted rice, but also provide a feasible implementation scheme to the conveying of the other greenhouse potted plants. The system mainly consists of the AGV system, the unpowered plantation trough, the transport line preparing for testing, the transport line for operation, the entrance-exit machine, the communication system, the control system, and so on. The potted rice can be moved by aid of the AGV and the transport line. In the cultivation area, all the unpowered plantation troughs are placed in rows and there are twenty-four pots of rice placed in each unpowered plantation trough. According to the instruction, the AGV can firstly pick up the unpowered plantation trough, and put it on the entrance-exit machine. And all the twenty-four pots of rice then enter the transport line at the same time. After that, all the pots of rice are moved to the designed test or operation positions in sequence. When all the tests or operations on the twenty-four pots of rice are completed, all the twenty-four pots of rice are moved to leave the transport line at the same time through the unpowered plantation trough, and then placed to their original position by using the AGV. The AGV is located accurately by the laser bar code with the positional accuracy of (±5) mm, and the maximum velocity of AGV is set at 60 m/min. The AGV moves smoothly and steadily when the AGV picking, placing or moving the unpowered plantation trough, so the trough can not fall easily. In this paper, 240 pots of rice were chosen randomly for the experiment on the transport of the potted rice. The results showed that the high throughput conveyor system of potted rice could meet the velocity requirement of the test for all the pots of rice, and the AGV could pick and place the troughs accurately. In addition, all the troughs were not dumped and had no collision with other objects. Furthermore, all the pots of rice were stable all the time when moving, and all the rice was intact. The equipment in the greenhouse can also be in regionalized management.
