Abstract
Description
Technical Field
[0001] The present application relates to the field of agricultural machinery technology, and in particular to an automatic seedling tray stacking mechanism. Background Art
[0002] The seedling tray is an essential component of a rice transplanter, primarily used to raise rice seedlings. Typically made of polyvinyl chloride (PVC), the tray undergoes a specialized process, resulting in lightweight, easy handling, storage, and low cost. The tray's design resists softening, deformation, and cracking within a certain temperature range (-20°C to 45°C).
[0003] During the production, use, and processing of seedling trays, it's necessary to stack unused trays together to reduce space or facilitate transportation. Manually stacking seedling trays is not only time-consuming and labor-intensive, but also inefficient. Manually stacking seedling trays on a seedling tray production line or processing line significantly slows down the process. Utility Model Content
[0004] In order to speed up the stacking of seedling trays and improve the efficiency and reduce the labor cost of stacking seedling trays, the present application provides an automatic stacking mechanism for seedling trays.
[0005] The present application provides an automatic stacking mechanism for seedling trays using the following technical solutions:
[0006] The lifting mechanism is arranged at the position of the tray feeding station, and the horizontal moving mechanism is arranged at the upper end of the frame and directly above the lifting mechanism. A tray stacking mechanism is provided at the upper end of the frame and directly above the lifting mechanism. A tray stacking mechanism is provided at the end of the horizontal moving mechanism away from the lifting mechanism, which is used to transport and stack the seedling trays delivered from the lifting mechanism.
[0007] By adopting the above technical solution, after the seedling tray is placed on the tray feeding mechanism, the tray feeding mechanism will automatically transport the seedling tray to the tray feeding station corresponding to the lifting mechanism, and then the seedling tray will be lifted by the lifting mechanism. When the seedling tray rises to the top of the frame, the horizontal moving mechanism pushes the seedling tray to leave the lifting mechanism and is placed above the tray stacking mechanism. Driven by the tray stacking mechanism, the seedling tray is automatically stacked and stacked. The process does not require manual real-time monitoring to achieve automatic stacking of the seedling trays. Since the conveying mechanisms at various positions of the seedling trays will change the position of the seedling trays during transportation, and the seedling trays are controlled by the mechanical structure during transportation, the device can realize the operation of cyclic stacking of the seedling trays, thereby greatly improving the efficiency of seedling tray stacking and reducing labor costs.
[0008] Optionally, the lifting mechanism includes two positioning frames symmetrically and integrally arranged on both sides of the frame along the width direction, two transmission shafts arranged at both ends of the positioning frames for vertical rotation, and a transmission member wound around the two transmission shafts located on the same positioning frame, a number of support plates for lifting the seedling tray are arranged at equal intervals on the outside of the transmission member, the two positioning frames are commonly connected to a synchronous drive device, and the two support plates on the two positioning frames located on the same horizontal plane are symmetrically abutted against the bottom side of the seedling tray.
[0009] By adopting the above technical solution, the tray feeding mechanism transports the seedling tray to the tray feeding station, and then the two symmetrically arranged support plates jointly lift the seedling tray, thereby ensuring the stability during the seedling tray transportation process. Since there are multiple support plates on the transmission part, the seedling tray from the tray feeding mechanism can be continuously lifted to ensure the continuous operation of the entire mechanism, so as to improve the stacking efficiency of the seedling tray.
[0010] Optionally, the horizontal moving mechanism includes a falling frame fixedly arranged on the top of the frame, and the falling frame is provided with rotating shafts at both ends along the horizontal direction, and the two rotating shafts are jointly wrapped with a transmission chain, and a number of paddles for pushing the seedling tray to move horizontally are arranged at intervals on the transmission chain, and the several paddles are vertically connected to the transmission chain.
[0011] By adopting the above technical solution, when the seedling tray moves to the top of the lifting mechanism, the rotating shaft drives the conveyor chain to work and drives the paddle on one side of the seedling tray to push the seedling tray horizontally away from the support plate and enter the position of the stacking mechanism. The operation is simple and will not cause the seedling tray to fall vertically. At the same time, when the lifting mechanism is intermittently operating, the movement of the seedling tray by the paddle can cooperate with the action of the lifting mechanism, thereby ensuring the efficient operation of the seedling tray stacking process.
[0012] Optionally, there are two transmission chains, and the two transmission chains are symmetrically connected to the two ends of the rotating shafts along the axis. The several paddles on the two transmission chains correspond one to one, and the two paddles located on the same plane are both in contact with the same end of the seedling tray.
[0013] By adopting the above technical solution, it can be ensured that the seedling tray will not tilt during the horizontal movement, so that it can enter the working position of the tray stacking mechanism straightly, reducing the probability of the seedling tray colliding. At the same time, it also helps to make the seedling tray evenly stressed when moving horizontally, avoiding excessive force at a certain position on the seedling tray, causing damage to the paddle, increasing the force area, and avoiding the use of a high-power drive motor.
[0014] Optionally, the stacking mechanism includes two pallet slides arranged at the top end of the frame away from the horizontal moving mechanism along the width direction of the frame and a stacking bracket arranged on the frame for vertical sliding. The two pallet slides are symmetrically slidably connected to the frame, and a limiting plate is provided at the top end of the frame away from the horizontal moving mechanism. The middle part of the stacking bracket is hollow and is provided directly above the tray discharging mechanism.
[0015] By adopting the above technical solution, the pallet slide plays a temporary lifting role to prevent the seedling tray from falling. The seedling tray then falls onto the stacking tray bracket for stacking. Since the stacking tray bracket is set to slide vertically, it can be moved to a position with a smaller distance from the lower side of the pallet slide, preventing the seedling tray from falling too high and causing damage, thereby playing a buffering role.
[0016] Optionally, the pallet slide and the top end of the lifting mechanism are located on the same horizontal plane.
[0017] By adopting the above technical solution, not only is the operation of the horizontal moving mechanism to move the seedling tray to the tray slide easier, but it can also avoid the seedling tray from being displaced in the vertical direction and causing collisions, thereby improving the smoothness of the overall operation of the mechanism.
[0018] Optionally, the tray feeding mechanism includes two limit rods symmetrically installed on one side of the frame near the bottom, and two tray feeding drag chains for dragging the seedling tray into the tray feeding station are symmetrically installed on the end of the frame near the lifting mechanism. The two tray feeding drag chains are commonly connected to a tray feeding drive motor, and the tray feeding drag chains abut against the bottom of the seedling tray.
[0019] By adopting the above technical solution, the limit rod can assist in lifting the seedling tray and limit the seedling tray at the same time, so as to help the seedling tray smoothly enter the tray entry position, and then be lifted by the lifting mechanism, thereby improving the smoothness and convenience of the mechanism entering the tray, saving manpower, and avoiding wear of the seedling tray.
[0020] Optionally, the tray discharge mechanism includes a tray discharge bracket slidably installed in the frame, a plurality of tray discharge chains that are driven and wound around the tray discharge bracket, and a plurality of guide rollers symmetrically installed on both sides of the tray discharge bracket along the width direction. The tray discharge bracket is located below the tray stacking bracket, and the plurality of tray discharge chains are arranged at equal intervals along the width direction of the tray discharge bracket.
[0021] By adopting the above technical solution, when the stacking tray bracket stacks a predetermined number of seedling trays, the seedling tray stack is placed on the tray discharge bracket, and the seedling tray stack is transported out by the tray discharge drag chain. The structure is simple and reduces labor. The function of the guide roller is to drive the seedling tray stack to move to prevent the seedling tray from being damaged due to relative friction between the bottom seedling tray and the tray discharge mechanism due to the inertia of the seedling tray stack when the tray discharge drag chain drags the seedling tray stack.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] 1. This application can continuously and stably transport and stack seedling trays, outputting seedling tray stacks with high efficiency, thereby greatly improving the efficiency of seedling tray stacking;
[0024] 2. The stacking operation of the seedling tray of the present application is completed automatically and integratedly by various parts of the mechanism, without the need for manual assistance or labor, thus saving manpower consumption;
[0025] 3. In the process of transporting the seedling tray, the seedling tray moves smoothly and will not be damaged due to collision or wear. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following is combined with Figure 1-7 This application is described in further detail.
[0035] The embodiment of the present application discloses an automatic stacking mechanism for seedling trays.
[0036] Reference Figure 1 , a mechanism for automatically stacking seedling trays, comprising a tray-feeding mechanism 1 for loading seedling trays, a lifting mechanism 2 for lifting the seedling trays to a predetermined height, a horizontal moving mechanism 3 for driving the horizontal displacement of the seedling trays, a tray-discharging mechanism 4 for conveying the stacked seedling trays, and a frame 5. The tray-discharging mechanism 4 and the tray-feeding mechanism 1 are respectively arranged at opposite ends of the frame 5. The frame 5 is provided with a tray-feeding station 51 on the same horizontal plane as the tray-feeding mechanism 1 at a position close to the tray-feeding mechanism 1, so that the seedling trays can be smoothly lifted by the lifting mechanism 2 after being conveyed by the tray-feeding mechanism 1, and the tray-feeding station 51 and the lifting mechanism 2 overlap in the vertical direction. The horizontal moving mechanism 3 is located at the top of the frame 5, and one end thereof overlaps with the lifting mechanism 2 in the vertical direction.
[0037] The end of the horizontal moving mechanism 3 away from the lifting mechanism 2 is connected to the tray stacking mechanism 6. When the seedling tray is lifted to the top of the frame 5, the horizontal moving mechanism 3 can immediately push the seedling tray to the tray stacking station of the tray stacking mechanism 6 for stacking. The tray stacking mechanism 6 is installed vertically above the tray discharge mechanism 4. When the tray stacking mechanism 6 stacks a predetermined number of seedling trays into a tray stack, it automatically places the tray stack onto the tray discharge mechanism 4.
[0038] Reference Figure 2Specifically, the lifting mechanism 2 includes two positioning frames 21 symmetrically arranged on the frame 5, two transmission shafts 22 at both ends of the positioning frames 21 that are respectively rotatable in the vertical direction, and a transmission member 23 wound around the two rotating shafts. Among them, the frame 5 has a lifting space for the seedling tray to pass through between the two positioning frames 21, and the transmission members 23 located on the two positioning frames 21 are symmetrically arranged on both sides of the lifting space. A plurality of support plates 24 for lifting the seedling tray are fixedly mounted on the transmission member 23 along the circumference, and the plurality of support plates 24 located on the two transmission members 23 are evenly spaced and correspond one to one. The two support plates 24 located on the same horizontal plane are respectively in contact with both sides of the bottom of the seedling tray along the length direction, thereby achieving the purpose of stably lifting the seedling tray.
[0039] It should be noted that the transmission member 23 described in this application is a cyclically rotating device, including but not limited to a chain and a conveyor belt.
[0040] Reference Figure 3 and Figure 4 Specifically, the horizontal moving mechanism 3 includes a drop frame 31 fixedly mounted on the top of the frame 5. The drop frame 31 is arranged in the horizontal direction, and its length is greater than the length of the seedling tray. Rotating shafts 32 are actively provided at both ends of the drop frame 31 in the horizontal direction, and a transmission chain 33 is wound around the two rotating shafts 32. The rotating shaft 32 is connected to a motor to drive the transmission chain 33 to work. A number of paddles 34 for pushing the seedling tray to move horizontally are arranged at intervals on the transmission chain 33, and the several paddles 34 are vertically connected to the transmission chain 33, so that the paddles 34 can be fully fitted with the side of the seedling tray when pushing the seedling tray, thereby avoiding excessive local squeezing force on the seedling tray, which may result in damage to the seedling tray.
[0041] Preferably, there are two transmission chains 33, symmetrically distributed along the axis of the rotating shaft 32. Both transmission chains 33 are equipped with paddles 34, with the paddles 34 of the two transmission chains 33 corresponding to each other. The two paddles 34, located on the same vertical plane, abut the same side of the seedling tray, thereby increasing the force-bearing area of the seedling tray, facilitating more efficient propulsion. This also avoids the need for a high-power drive motor, reducing overall power consumption.
[0042] Reference Figure 5 Specifically, the tray stacking mechanism 6 includes two tray slides 61 symmetrically arranged on the end of the frame 5 away from the lifting mechanism 2, and a tray stacking bracket 62 slidably mounted on the frame 5. The two tray slides 61 are symmetrically slidably connected to the frame 5 and are used to receive the seedling trays from the horizontal moving mechanism 3. The tray stacking bracket 62 is located below the two tray slides 61 and is used to receive the seedling trays and stack them into stacks. The center of the tray stacking bracket 62 is hollowed out to ensure that the seedling tray stack can be smoothly placed on the tray discharging mechanism 4, while also preventing wear on the seedling trays when the stack is released.
[0043] Preferably, a limit plate 52 is installed on the top of the end of the frame 5 away from the tray feeding mechanism 1 to prevent the seedling tray from the horizontal moving mechanism 3 from flying out of the frame 5 under the action of inertia, so as to facilitate more orderly stacking of the seedling trays.
[0044] Preferably, the tray slide 61 and the horizontal movement mechanism 3 are located on the same horizontal plane. When the seedling tray moves to the top of the lifting mechanism 2, the paddle 34 can smoothly slide it to the predetermined position on the tray slide 61, preventing the seedling tray from vertically shifting and potentially falling and being damaged, thereby improving the overall stability of the structure. This also makes the seedling tray move more regularly, helping to improve the operating efficiency of the equipment.
[0045] Reference Figure 6 The tray feeding mechanism 1 includes two symmetrically mounted limit rods 11 on one side of the frame 5 near the bottom, which facilitate workers or machines to place the seedling trays onto the tray feeding mechanism 1. Two tray feeding drag chains 12 are symmetrically mounted on the frame 5 at the positions of the limit rods 11 to drag the seedling trays placed on the limit rods 11 into the tray feeding station 51 within the frame 5. The tray feeding drag chains 12 abut against the bottom of the seedling tray, and the two tray feeding drag chains 12 are jointly connected to the tray feeding drive motor 13 to achieve synchronous rotation of the two tray feeding drag chains 12, thereby jointly dragging the seedling trays.
[0046] It should be noted that the limiting rod 11 in the present application can also play a role in assisting the seedling tray to prevent excessive friction between the seedling tray and the tray inlet drag chain 12. At the same time, the limiting rod 11 can also limit the seedling tray and promote the seedling tray to enter the tray inlet station 51 more smoothly.
[0047] Reference Figure 7 Specifically, the tray discharge mechanism 4 includes a tray discharge bracket 41 slidably mounted within the frame 5, a plurality of tray discharge chains 42 that are driven and wound around the tray discharge bracket 41, and a plurality of guide rollers 43 symmetrically mounted on both sides of the tray discharge bracket 41 along the length direction. One end of the tray discharge bracket 41 and the plurality of guide rollers 43 are mounted directly below the tray stacking bracket 62. When the tray stacking mechanism 6 completes the tray stacking operation, the tray stacking bracket 62 moves downward and places the seedling tray stack on the tray discharge chain 42. The tray discharge chain 42 then drags the seedling tray stack out of the entire mechanism.
[0048] In this application, several tray discharge chains 42 are arranged on the tray discharge bracket 41 at equal intervals along the width of the tray discharge bracket 41. Because the seedling trays are heavy, the number of tray discharge chains 42 on the tray discharge bracket 41 is greater than the number of tray inlet chains 12 to ensure sufficient power to drive the seedling trays. Furthermore, the tray discharge bracket 41 is slidably connected to the frame 5 to facilitate connection to an external tray receiving device.
[0049] In the present application, the guide roller 43 provides auxiliary support to prevent the static friction of the tray-dispensing drag chain 42 from being large when being dragged by the tray-dispensing drag chain 42, thereby causing wear on the bottom of the seedling tray.
[0050] The implementation principle of the automatic stacking mechanism of a seedling tray in the embodiment of the present application is as follows:
[0051] After the seedling tray is placed on the limiting rod 11, the seedling tray will enter the tray feeding station 51 located inside the frame 5 under the drive of the tray feeding drag chain 12. Afterwards, the lifting mechanism 2 moves in a circular motion and continuously lifts the seedling tray on the tray feeding station 51 to the top of the frame 5.
[0052] Then, the seedling tray lifted to the top of the frame 5 is moved to the tray slide 61 on the other side of the frame 5 by the paddle 34 on the horizontal moving mechanism 3. At this time, the stacking tray bracket 62 is driven close to the tray slide 24, and the two tray slides 61 slide relative to each other in a direction away from each other, so that the seedling trays continue to fall onto the tray slide 61 and stack into a stack.
[0053] Finally, the seedling tray stack is placed on the tray discharge bracket 41 under the movement of the tray stacking bracket 62, and is driven by the tray discharge drag chain 42 to be transported out of the entire mechanism.
[0054] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
