When the pot seedling tray is used, the pot seedlings a form a paper pot seedling tray which is arranged in a composite manner as shown in fig. 1, the paper pot seedling tray is manually unfolded into a pot chain, the pot chain is unfolded and laid on the conveying belt 1, the pot seedlings a are in a lying state (namely, the pot bodies are not contacted with the conveying belt 1 at the bottom but contacted with the conveying belt 1 at the side walls), and the center distance between the first roller body 21 and the second roller body 22 is equal to the center distance between two adjacent pot seedlings a in the pot chain; the conveyor belt 1 conveys the pot seedlings to the position of the seedling separating mechanism 2, the first roller body 21 and the second roller body 22 act on two pot seedlings a respectively, and as the two roller bodies have the same rotating speed and different diameters, the surface linear speed of the first roller body 21 is greater than that of the second roller body 22, so that the movement speeds of the pot seedlings a acted by the two roller bodies are different, the distance between the two pot seedlings a is gradually increased, and the two pot seedlings a can be separated, so that seedling separation is realized.
Preferably, the conveyor belt 1 is driven by a driving roller, the driving roller is driven by a motor 3 to rotate, and a first synchronous gear set 5 and a second synchronous gear set 6 are respectively arranged between a shaft body 4 of the driving roller and the first roller body 21 and between the shaft body 4 of the driving roller and the second roller body 22; the first synchronous gear set 5 is composed of two gears with equal tooth numbers, the two gears are respectively coaxially arranged with the shaft body 4 and the first roller body 21, the second synchronous gear set 6 is composed of two gears with equal tooth numbers, the two gears are respectively coaxially arranged with the shaft body 4 and the second roller body 22, so that the rotation speeds of the first roller body 21, the second roller body 22 and the shaft body 4 are equal, and the rotation speeds of the first roller body 21, the second roller body 22 and the driving roller are opposite. Preferably, the radius of the second roller 22 is equal to the sum of the radius of the driving roller and the thickness of the conveying belt 1, so that the surface linear speed of the second roller 22 is equal to the surface linear speed of the conveying belt l, and the moving direction of a point on the second roller 22, which is close to the conveying belt 1, is consistent with the moving direction of a point on the upper end surface of the conveying belt 1, so that the second roller 22 and the conveying belt 1 form a clamping effect on the pot seedling a, the normal speed of the pot seedling a can be maintained, the second roller 22 does not drag the traveling speed of the pot seedling a, and the separated pot seedling a does not drag the whole pot chain, so that the speed is increased.

A tensioning mechanism 10 is arranged between the head end of the conveying belt 1 and the first side plate 7 and the second side plate 8.
The tail end of the conveying belt 1 is provided with a guide hopper 9, and the guide hopper 9 is vertically arranged. Thus, when the seedlings a are arranged on the conveyor belt 1, the bottoms of the seedlings a are propped against under the action of gravity, so that the seedlings can be kept tidy, the roots of the separated seedlings a can be inclined downwards, and the correct posture of the seedlings a after falling down can be ensured through the guide hopper 9.
Correspondingly, the first roller body 21 and the second roller body 22 are both installed on the obliquely upper side of the second side plate 8, the first synchronous gear set 5 and the second synchronous gear set 6 are both installed on the obliquely lower side of the second side plate 8, and the motor 3 is connected with the first side plate 7 through a motor bracket.

In order to grasp the timing of spraying water, the first roller body 21 and the second roller body 22 are respectively connected with the first synchronous gear set 5 and the second synchronous gear set 6 through pressure sensors, that is, a first pressure sensor is arranged between the first roller body 21 and a first shaft connected with the first synchronous gear set 5, and a second pressure sensor is arranged between the second roller body 22 and a second shaft connected with the second synchronous gear set 6. The first pressure sensor, the second pressure sensor and the water spraying mechanism 11 are all connected with the controller, and the controller judges whether the first pressure sensor and the second pressure sensor generate pressure signals exceeding a preset value at the same moment (the two pressure sensors generate pressure signals to indicate that the first roller 21 and the second roller 22 are both pressed to the pot seedling a and receive the reaction force of the pot seedling a), so that the water spraying mechanism 11 is controlled to spray quantitative water. By the method, the water spraying time can be effectively controlled, water is sprayed only when necessary to carry out the de-sizing, the water is saved, and the problem that the paper pot is easy to damage and the subsequent planting operation is influenced due to the fact that the pot seedling a is wetted by water through direct current can be prevented.
