[0002] The seedling tray is an indispensable component of a rice transplanter, and its main function is to realize the seedling raising process of rice seedlings. The seedling tray is made of polyvinyl chloride as raw material and processed by special process formula through thermoforming. It has the characteristics of light weight, easy handling, convenient storage and low use cost.

[0003] The seedling tray can be reused. In existing large-scale seedling raising bases, it is necessary to frequently collect and place the seedling trays. Once the seedling trays are used, they are directly placed on the ground. The collection and placement mainly rely on manual labor, with very low efficiency. With the improvement of mechanical automation level, there is also a situation of using mechanical equipment to place the seedling trays. For example, the Chinese patent document with the publication number CN213280636U discloses an automatic seedling tray placing device for paddy fields. When distributing the seedling trays to the fields, it is necessary to use a tray separating mechanism to push the seedling trays onto a turnover mechanism, and the turnover mechanism flips the seedling trays so that the seedling trays slide off the placing mechanism to complete the placing work. However, this placing device can only complete the work of placing the seedling trays from the placing device to the fields, and cannot realize the work of collecting the seedling trays from the fields to the placing device.

[0023] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings and embodiments. What is described here is only the preferred embodiment of the utility model. Those skilled in the art can think of other ways to implement the utility model based on the preferred embodiment, and other ways also fall within the scope of the utility model.

[0024] Example 1

[0025] Reference Figures 1 - 3 This embodiment provides a tray closing mechanism, including an upper tray assembly 1 and a temporary storage area 2. One end of the upper tray assembly 1 is connected to the temporary storage area 2. The upper tray assembly 1 transfers the seedling tray from the field to the temporary storage area 2. The temporary storage area 2 is provided with a tray closing assembly 3. A tray closing opening 201 is provided on one side of the temporary storage area 2. The tray closing assembly 3 pushes the seedling tray out of the tray closing opening 201 of the temporary storage area 2. The upper tray assembly 1 and the tray closing assembly 3 can transport the seedling tray from the field to the temporary storage area 2 and push it out of the tray closing opening 201 of the temporary storage area 2, so that the seedling tray enters the next circulation mechanism of the tray closing machine, realizing the recovery of the seedling tray from the field to the tray closing machine.

[0026] In this embodiment, the closing assembly 3 cannot do without the power mechanism when performing the tray pushing action. The closing assembly 3 includes a driving mechanism and a driven component. The driving mechanism is in transmission connection with the driven component. The driving mechanism causes the driven component to reciprocate in the first direction, and the driven component pushes the seedling tray out of the closing opening 201, wherein the first direction is the direction toward the closing opening 201. When pushing the tray, the driven component moves toward the closing opening 201; after the tray pushing is completed, the driven component moves in the direction away from the closing opening 201, and the driven component returns to its original position.

[0027] Specifically, Figure 1 and Figure 2As shown in the figure, the driving mechanism includes a motor 301, and the driven components include driven shafts 302 arranged on both sides of the temporary storage area 2. The motor 301 is drivingly connected to the driven shafts 302. The motor 301 and the driven shafts 302 can be connected by gears, or by a chain and sprockets. When the motor 301 rotates, the driven shafts 302 rotate. Belt pulleys 305 are arranged on the driven shafts 302, and the belt pulleys 305 on the driven shafts 302 on both sides are connected by a transmission belt 303. A push block 304 is arranged on the transmission belt 303, and the push block 304 moves along with the transmission belt 303. On the one hand, the transmission belt 303 serves to connect the driven shafts 302 on both sides. On the other hand, the transmission belt 303 can drive the push block 304 to reciprocate in the first direction, serving to push the seedling tray.

[0028] Further, please refer to Figure 1 and Figure 2 In this embodiment, a transition area 4 is arranged on one side of the closing port 201 of the temporary storage area 2. The transition area 4 is used for the transition of the seedling tray from the temporary storage area 2 to the next mechanism, increasing the smoothness when the seedling tray is pushed out from the temporary storage area 2. To ensure that the seedling tray can be smoothly transitioned in the transition area 4, a resistance reduction mechanism is arranged in the transition area 4. The resistance reduction mechanism is used to reduce the moving resistance of the seedling tray. Specifically, the resistance reduction mechanism includes a plurality of rollers 401, and the plurality of rollers 401 are arranged along the moving direction of the seedling tray. The outer side surface of the roller 401 is in direct contact with the bottom of the seedling tray. The roller 401 can rotate along its own axial direction, which can reduce the resistance of the seedling tray moving on the roller 401 and improve the transition efficiency of the seedling tray.

[0029] In this embodiment, as Figure 1 and Figure 3 shown, the upper tray assembly 1 includes an upper tray conveying frame 101. One end of the upper tray conveying frame 101 extends towards the ground, and the other end is connected to the temporary storage area 2. A conveying chain 102 is arranged on the upper tray conveying frame 101. The conveying chain 102 conveys the seedling tray from the ground end of the upper tray conveying frame 101 to one end of the temporary storage area 2. A limiting structure is arranged on the contact surface of the conveying chain 102 with the seedling tray. The limiting structure is used to limit the seedling tray from slipping during closing. The limiting structure can be a convex structure, and the convex structure can increase the stability of the contact between the bottom of the seedling tray and the conveying chain 102. The closing mechanism further includes a traveling mechanism 5, and the traveling mechanism 5 is distributed on both sides of the temporary storage area 2. The traveling mechanism 5 is used to drive the temporary storage area 2 and the upper tray assembly 1 to move. During the movement of the upper tray assembly 1, the end close to the ground can shovel up the seedling tray by means of the moving force, facilitating the movement of the seedling tray from the upper tray assembly 1 into the temporary storage area 2. To improve the tray lifting efficiency of the upper tray assembly 1, a tray lifting assembly 103 is arranged at the end of the upper tray assembly 1 close to the ground. The tray lifting assembly 103 preferentially contacts the ground. The tray lifting assembly 103 has a relatively sharp end, which can smoothly shovel up the seedling tray.

[0031] On the basis of the first embodiment, different from the first embodiment, the driving mechanism includes a cylinder or an electric push rod, and a push block 304 is arranged at the output end of the cylinder or the electric push rod. The telescopic action of the cylinder or the electric push rod can also drive the push block 304 to reciprocate in the first direction, thereby completing the action of pushing the tray.

[0032] Another aspect of the present application further provides a tray collector, including the above-mentioned tray collecting mechanism, and the tray collecting mechanism is detachably connected to the tray collector. When the tray collector is transported, the tray collecting mechanism can be disassembled to facilitate transportation. On the other hand, the detachable tray collecting mechanism means that the tray collecting mechanism has a high degree of freedom and can be installed on different sides of the tray collector to achieve tray collecting actions in different directions, improving the tray collecting efficiency and environmental adaptability of the tray collector.
