When the first rotating shaft rotates, the first transmission component drives the conveying disc to rotate.

[0004] Although the aforementioned tray-laying machine, also known as a tray-separating machine, can separate stacked seedling trays using a destabilizing component, seedling trays come in different sizes, such as 7-inch and 9-inch trays. The same destabilizing component cannot destabilize seedling trays of different sizes. Utility Model Content

[0036] The present invention will now be described in detail with reference to the accompanying drawings. The embodiments described herein are merely preferred embodiments of the present invention. Those skilled in the art can conceive of other ways to implement the present invention based on the preferred embodiments, and such other ways also fall within the scope of the present invention.

[0037] Reference Figures 1-8 This embodiment provides a seedling tray separating machine, including a frame 100, a first conveying mechanism 200, a second conveying mechanism 300, and a destacking mechanism. The first conveying mechanism 200 and the second conveying mechanism 300 are arranged sequentially on the frame 100 according to the seedling tray conveying direction. The destacking mechanism is located at a position corresponding to the second conveying mechanism 300, specifically above the second conveying mechanism 300, and is used to send the stacked seedling trays one by one onto the second conveying mechanism 300. The destacking mechanism can separate the stacked seedling trays one by one, and the second conveying mechanism 300 transports the separated seedling trays to the next station.

[0038] Common seedling trays come in 7-inch and 9-inch sizes, and traditional tray separating machines cannot disassemble trays of different sizes. Therefore, a disassembly mechanism, as part of the tray separating machine, includes two sets of disassembly components located on opposite sides of the frame 100. These components are movably positioned relative to the frame 100. The two disassembly components are connected by an adjusting member 530, which allows them to move closer or further apart. The adjusting member 530 can reduce or increase the distance between the disassembly components on both sides of the frame 100, enabling the machine to accommodate and separate stacked seedling trays of different sizes one by one, thus improving the versatility and efficiency of the tray separating machine.

[0039] In some embodiments, such as Figure 3 , Figure 4 and Figure 5 As shown, the adjusting component 530 includes an adjusting screw 531. Both sides of the destacking assembly are provided with screw mounting positions, and the adjusting screw 531 connects the two sides of the destacking assembly through these mounting positions. The screw mounting positions on both sides have threads with the same direction of rotation, while the adjusting screw 531 has threads with opposite directions of rotation corresponding to the screw mounting positions on both sides. Alternatively, the screw mounting positions on both sides have threads with opposite directions of rotation, while the adjusting screw 531 has threads with the same direction of rotation corresponding to the screw mounting positions on both sides. The opposite rotation direction of the adjusting screw 531 to the screw mounting positions allows the destacking assemblies on both sides of the frame 100 to move closer or further apart when the adjusting screw 531 is rotated, thereby adjusting the distance between the destacking assemblies and enabling the destacking mechanism to separate seedling trays of different sizes.

[0040] It should be noted that the destabilizing components on both sides have a certain length. To ensure the stability and synchronicity of the destabilizing components during movement, two adjusting screws 531 are provided. These two adjusting screws 531 are arranged at intervals along the length of the destabilizing components, located near both ends of the components. The two adjusting screws 531 are connected by a synchronizing component, which causes the two adjusting screws 531 to rotate synchronously, thereby driving the destabilizing components on both sides to move synchronously. Specifically, the synchronizing component can be a chain and sprocket assembly, a synchronizing gear assembly, or a synchronizing belt assembly. When a chain and sprocket assembly is used, the sprockets are mounted on each adjusting screw 531, and the sprockets on the two adjusting screws 531 are connected by a chain. It can be understood that the structure of a synchronizing belt is similar to that of a chain and sprocket assembly. A synchronizing gear assembly consists of one synchronizing gear mounted on each adjusting screw 531, with the two synchronizing gears meshing externally or through an intermediate gear.

[0041] In some embodiments, such as Figure 4As shown, the destacking components on both sides are the first and second sets of destacking components, respectively. Each set of destacking components includes a destacking beam 520, on which several destacking parts 510 are mounted. The destacking beam 520 is movably connected to the frame 100. Specifically, the bottom of the destacking beam 520 has a notch, and the frame 100 has a track corresponding to the notch. The destacking beam 520 is slidably connected to the track of the frame 100 through the notch. The adjusting component 530 is connected to the destacking beams 520 on both sides and controls the destacking beams 520 on both sides to move synchronously in opposite directions. The length direction of the destacking beam 520 is consistent with the length direction of the frame 100. The destacking beam 520 serves as the mounting base for the destacking parts 510, which can move together with the destacking beam 520, thereby adjusting the spacing between the destacking parts 510 on both sides.

[0042] Furthermore, the first and second sets of destacking beams 520 are each equipped with independent drive components. The destacking components 510 on the destacking beams 520 of the same set are connected to the same drive component and controlled by the same drive component to move synchronously. Specifically, the destacking components 510 on the first set of destacking beams 520 are driven synchronously by the first drive component, and the destacking components 510 on the second set of destacking beams 520 are driven synchronously by the second drive component. The synchronous movement of the destacking components 510 on the same set of destacking beams 520 ensures the accuracy of tray removal, reduces errors, protects the seedling trays, and prevents damage to the seedling trays caused by asynchronous movement that could lead to pulling or squeezing.

[0043] In some embodiments, such as Figure 6 As shown, the destacking component 510 includes a destacking screw 511 and a destacking rod 512, the destacking rod 512 being rotatably connected to the destacking beam 520; the destacking screw 511 is arranged in a spiral along the axial direction of the destacking rod 512. The second drive assembly includes a synchronous pulley 513, a synchronous belt 514, and a destacking drive component 515; the destacking rod 512 is sleeved with the synchronous pulley 513, and the synchronous pulleys 513 on the same group of destacking rods 512 are connected by the synchronous belt 514; one of the destacking rods 512 is connected to the destacking drive component 515, and the destacking drive component 515 drives the destacking rod 512 to rotate around its axial direction. Specifically, in this embodiment, two destabilizing components 510 are provided on the same set of destabilizing beams 520, and a total of four destabilizing components 510 are provided on both sides of the destabilizing beams 520. The destabilizing screws 511 of the four destabilizing components 510 support the lowest seedling tray. When the four destabilizing components 510 rotate simultaneously, the seedling tray moves downward under the guidance of the destabilizing screws 511 until it detaches from the destabilizing screws 511 and falls onto the second conveying mechanism 300 under the action of gravity. The second conveying mechanism 300 transports the seedling tray to the next station. It should be noted that the destabilizing screws 511 on the first set of destabilizing beams 520 and the second set of destabilizing beams 520 rotate in opposite directions. The destabilizing drive component 515 is a motor.

[0044] It is understandable that the destacking component 510 can also adopt other structures, such as a cylindrical gear structure, with the gear face facing the seedling tray. The cylindrical gear rotates axially, and the rotation of the gear face realizes the separation of the seedling tray.

[0045] In some embodiments, such as Figure 7 As shown, the seedling tray sorting machine also includes a conveying assembly 400. Two sets of conveying assemblies 400 are arranged on opposite sides of the frame 100. The conveying assemblies 400 support stacked seedling trays from the first conveying mechanism 200. The conveying assemblies 400 are positioned corresponding to the second conveying mechanism 300. The conveying plane of the first conveying mechanism 200 is higher than that of the second conveying mechanism 300. This height difference allows the stacked seedling trays transported by the first conveying mechanism 200 to transition onto the conveying assembly 400. The destacking mechanism separates the seedling trays supported by the conveying assembly 400, disassembling the stacked seedling trays one by one onto the second conveying mechanism 300, which then transports them one by one to the next workstation.

[0046] Furthermore, the conveying assembly 400 includes a conveying disk 410 and a conveying base plate 420. The conveying base plate 420 is fixedly mounted on the frame 100. The conveying disk 410 is slidably disposed above the conveying base plate 420. The conveying base plate 420 is provided with a linear drive mechanism 430, which drives the conveying disk 410 to move linearly, causing the two conveying disks 410 on both sides to move closer or further apart. The conveying disk 410 is the component that directly supports the seedling tray. When the seedling tray is about to be conveyed from the first conveying mechanism 200 to the position of the second conveying mechanism 300, the two conveying disks 410 on both sides move closer together to support the seedling tray. When the conveying disks 410 move further apart, the conveying disk 410 can be pulled away from the bottom of the seedling tray, allowing the seedling tray to fall onto the destacking screw 511 of the destacking member 510. The destacking screw 511 rotates, causing the seedling trays to move downward one by one. It can be understood that the conveying disk 410 is positioned above the top of the destacking member 510.

[0047] More specifically, such as Figure 7 and Figure 8 As shown, the conveyor plate 410 is slidably connected to the conveyor base plate 420 via a guide rail 440 and a sliding plate 470. The guide rail 440 is fixed to the upper surface of the conveyor base plate 420, and the sliding plate 470 is mounted on the guide rail 440 and slidably connected to it. The connection between the guide rail 440 and the sliding plate 470 provides excellent stability and increases the smoothness of the conveyor plate 410's movement. A linear drive mechanism 430 pushes the sliding plate 470 to slide on the guide rail 440. The linear drive mechanism 430 can be a cylinder, a hydraulic cylinder, or an electric actuator.

[0048] Understandably, when the stacked seedling trays are conveyed from the first conveying mechanism 200 to the conveying assembly 400, they will continue to move forward due to inertia. However, relying solely on inertia, the seedling trays cannot move to the appropriate position. Based on this phenomenon, in some embodiments, such as...Figure 8 As shown, the center of the conveyor disk 410 is connected to one end of the rotating shaft 480. The rotating shaft 480 is mounted on the slide plate 470 and passes through the slide plate 470 to connect with the rotating drive component 450. The rotating drive component 450 drives the conveyor disk 410 to rotate around its center. When the conveyor disk 410 rotates, its rotation direction causes the seedling tray to continue moving in the conveying direction. It can be understood that the rotation directions of the conveyor disks 410 on opposite sides are opposite, that is, one side of the conveyor disk 410 rotates counterclockwise, and the other side of the conveyor disk 410 rotates clockwise. Furthermore, the conveyor base plate 420 is provided with a clearance groove 460 along the linear movement direction of the slide plate 470 to avoid the rotating shaft 480 and prevent structural interference between the rotating shaft 480 and the conveyor base plate 420 when the conveyor disk 410 moves linearly with the slide plate 470.

[0049] Furthermore, in some embodiments, such as Figure 1 and Figure 2 As shown, a limiting component 600 is provided on the frame 100 corresponding to the position of the second conveying mechanism 300. The limiting component 600 includes side baffles 610 and a rear baffle 630 located on both sides of the second conveying mechanism 300. A side baffle 620 is provided inside the side baffles 610. The side baffles 610 and the side baffles 620 can prevent the stacked seedling trays from tilting during the conveying process. The rear baffle 630 can be used with the conveying component 400 to stop the stacked seedling trays, so that the seedling trays are stopped in a suitable position to wait for separation. A gap is left between the bottom of the rear baffle 630 and the second conveying mechanism 300 for the seedling trays to pass through. A control box 700 is provided on the frame 100 near the output end of the second conveying mechanism 300. The control box 700 is mounted above the second conveying mechanism 300 by a box bracket 710. A gap is left between the box bracket 710 and the conveying surface of the second conveying mechanism 300 for the seedling trays to pass through. The control box 700 contains electrical control components used to control the operation of the entire dispensing machine.
