Description

Technical Field

[0001] This utility model belongs to the field of plant seedling technology, specifically relating to a seedling tray storage and lifting device. Background Technology

[0002] Vegetables are an indispensable part of our daily lives; they are not only delicious but also rich in nutrients. To improve survival rates when vegetables are grown on a large scale, they must first be raised as seedlings, and then transplanted once the seedlings have grown to a certain height. Paper chain seedling technology is an innovative seedling method that uses biodegradable paper materials to create chain-like seedling containers. It is mainly applied to the seedling stage of crops such as vegetables and flowers. This technology combines environmental protection with agricultural efficiency, making it particularly suitable for large-scale seedling production.

[0003] The paper chain seedling raising process involves unfolding a long, strip-shaped paper chain into a honeycomb structure, securing the unfolded paper chain with a seedling tray, and then performing sowing and soil covering operations. Therefore, the placement and movement of the seedling tray determines the efficiency and quality of the paper chain seedling raising operation. Currently, the movement of seedling trays mainly relies on manual labor; no truly mature automated equipment has yet emerged, resulting in low efficiency and high costs for manual operation. Traditional methods using conveyor belts to transport seedling trays are costly due to the high manufacturing cost of such conveyor belts, and they mostly operate horizontally on the same plane. Achieving vertical movement often requires additional transport equipment. This leads to high manufacturing costs, demanding coordination between different devices, and a significant risk of seedling trays falling during transport, impacting final seedling production efficiency. Therefore, there is an urgent need for a device that can automatically transport seedling trays, unfold the paper chain, cover the substrate, and precisely sow, completely streamlining the unmanned production line for "seedling tray movement in paper chain seedling raising."

Detailed Implementation

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0029] like Figures 1 to 10As shown, this utility model provides a seedling tray storage and lifting device, including a support 1. The support 1 is equipped with a seedling tray storage module 2, a seedling tray moving module 3, and a seedling tray lifting module 4. The seedling tray moving module 3 is located at the bottom of the seedling tray storage module 2. The seedling tray storage module 2 includes a storage frame 21, which has an open structure at the top and bottom, with the middle for placing the seedling tray. The seedling tray moving module 3 includes a moving module slide rail 31 and a moving module crossbar 32. The moving module crossbar 32 is slidably connected to the moving module slide rail 31, and a push plate 33 is provided on the moving module crossbar 32. The seedling tray lifting module 4 includes a first lifting device 41, a lifting frame 42, a second lifting device 43, and a lifting platform 44. Two first lifting devices 41 are symmetrically distributed on both sides of the lifting frame 42, and the first lifting devices 41 drive the lifting frame 42 to move up and down. The second lifting devices 43 are located inside the lifting frame 42 and are connected to the lifting platform 44, driving the lifting platform 44 to move up and down. When the horizontal bar 32 of the moving module moves along the slide rail 31 of the moving module, the push plate 33 pushes the seedling tray located at the bottom of the storage frame 21 onto the lifting platform 44, and then the seedling tray moves up and down under the action of the first lifting device 41 and the second lifting device 43.

[0030] like Figure 2 As shown, in this embodiment, the support 1 is a frame structure composed of existing profiles, used to install the seedling tray storage module 2, the seedling tray moving module 3, and the seedling tray lifting module 4. The storage frame 21 has two storage frame crossbars 22, arranged symmetrically. The seedling tray is a cuboid with concave end faces, and both end faces of the storage frame 21 are open. The end of the storage frame crossbar 22 is flush with the end face of the storage frame 21, and the other end of the crossbar 22 extends out of the storage frame 21. Multiple seedling trays are stored in the storage frame 21, and the seedling trays are vertically stacked on the storage frame crossbar 22. During movement, the moving module crossbar 32 pushes the bottommost stacked seedling tray from its storage position to the lifting platform 44 via the push plate 33. As the previous seedling tray is pushed away, the next stacked seedling tray falls. When the push plate 33 moves backward, it flips over, and after passing the bottom of the seedling tray, it smoothly returns to its initial position.

[0031] The first lifting device 41 includes a first lifting mounting plate 410, a first lifting motor 411, a first lifting screw rod 412, and a first lifting slider 413. The first lifting motor 411 is installed at the end of the first lifting mounting plate 410, and the rotating shaft end of the first lifting motor 411 is connected to the first lifting screw rod 412. The first lifting slider 413 is sleeved on the first lifting screw rod 412 to form a screw-nut motion structure. When the first lifting screw rod 412 rotates, it drives the first lifting slider 413 to reciprocate. In this embodiment, the first lifting mounting plate 410, the first lifting motor 411, the first lifting screw rod 412, and the first lifting slider 413 form an existing mature screw-nut motion device, and the model of this device is: GGP double optical axis ball screw linear module guide aluminum transmission slide table with a 57 stepping motor. The first lifting mounting plate 410 is fixedly connected to the frame 1 by bolts.

[0032] In this embodiment, the first lifting mounting plate 410 is strip-shaped, and its cross-section is in a "mountain" shape structure. The first lifting screw rod 412 is arranged along the long side direction of the first lifting mounting plate 410. The first lifting slider 413 is located in the groove in the middle of the first lifting mounting plate 410 and can reciprocate along the axis direction of the first lifting screw rod 412 in the groove.

[0033] The cross-section of the lifting frame 42 is in a "U" shape. The second lifting device 43 is installed at the bottom of the lifting frame 42. The side of the lifting frame 42 is provided with a lifting frame through hole 420, a lifting frame through groove 421, a lifting frame guide rod 422, and a right-angle bracket 423. The number of the right-angle brackets 423 is two, and the two right-angle brackets 423 are respectively located at both ends of the lifting frame guide rod 422. Both ends of the lifting frame guide rod 422 are respectively connected to the lifting frame through hole 420 and the lifting frame through groove 421 through the two right-angle brackets 423. By adjusting the position of the right-angle bracket 423 in the lifting frame through groove 421, the inclination of the lifting frame guide rod 422 can be adjusted.

[0034] The right-angle bracket 423 is in a plate-like structure and is a bending connecting piece formed by bending 90 degrees. One end of the right-angle bracket 423 is connected to the lifting frame guide rod 422 by bolts, and the other end of the right-angle bracket 423 is respectively connected to the lifting frame through hole 420 and the lifting frame through groove 421 by bolts. That is, after passing bolts through the lifting frame through hole 420 and the lifting frame through groove 421 respectively, bolt connections are formed with the right-angle bracket 423. By adjusting the position of the bolts in the lifting frame through groove 421, the relative positions between the two right-angle brackets 423 can be adjusted.

[0035] The lifting frame through slot 421 is an arc-shaped through slot structure. The tilt of the lifting frame guide rod 422 can be adjusted by adjusting the position of the bolts on the right-angle bracket 423 connected to the end of the lifting frame guide rod 422 within the lifting frame through slot 421. In this example, both the lifting frame through slot 421 and the lifting frame guide rod 422 are two in number and symmetrically distributed on both sides of the lifting frame 42. The lifting frame 42 is connected to the first lifting slider 413 by bolts. During the reciprocating motion of the first lifting slider 413, it drives the lifting frame 42 to move synchronously.

[0036] The lifting platform 44 has a U-shaped cross-section, and the seedling tray is placed in the middle of the lifting platform 44. After the seedling tray is placed on the lifting platform 44, the upward-curving structure at both ends can limit the position of the seedling tray.

[0037] The push plate 33 has an "L"-shaped cross-section, and its two ends are rotatably connected to the moving module crossbar 32. In this embodiment, the push plate 33 includes a first plate 331 and a second plate 332 fixedly connected together. The portion connecting the first plate 331 and the second plate 332 protrudes outward to form a push plate pivot 333. The first plate 331 has a first plate through hole, and the first plate 331 and the second plate 332 form an included angle. The weight of the second plate 332 is greater than the weight of the first plate 331. In the initial state, the second plate 332 is located on the moving module crossbar 32. After the seedling tray moving module 3 pushes the seedling tray through the push plate 33, during the reset process, the side of the first plate 331 facing its included angle contacts the seedling tray to be moved, and at the same time drives the push plate 33 to rotate. The push plate 33 moves at the bottom of the seedling tray until it returns to the initial position. Since the weight of the second plate 332 is greater than that of the first plate 331, the second plate 332 drives the first plate 331 to flip in the opposite direction under the action of gravity, and the push plate 33 completes the reset.

[0038] The cross section of the moving module crossbar 32 is convex. The protruding part of the moving module crossbar 32 is provided with a crossbar fixing block 321. The two ends of the push plate 33 pass through the crossbar fixing block 321 and form a rotatable connection. The two ends of the moving module crossbar 32 are equipped with crossbar connectors 322. The back of the crossbar connector 322 is fixed with a crossbar connector slider 323, which is slidably connected to the moving module slide rail 31.

[0039] In this embodiment, the push plate rotating shaft 333 passes through and is rotatably connected to the crossbar fixing block 321. The crossbar fixing block 321 has a crossbar fixing block through hole, and the end of the push plate rotating shaft 333 is located in the crossbar fixing block through hole. The bottom of the moving module crossbar 32 is provided with a sine mechanism 34, which includes a moving module motor 341, a moving module connecting rod 342, and a moving module slider 343. The rotating shaft end of the moving module motor 341 is connected to the end of the moving module connecting rod 342, and the other end of the moving module connecting rod 342 is rotatably connected to the bottom of the moving module slider 343. The moving module motor 341 is fixedly mounted on the frame 1. The bottom of the moving module crossbar 32 is provided with a cuboid moving module crossbar slide rail 324, and the other side of the moving module slider 343 is a concave structure. The moving module slider 343 is engaged with the moving module crossbar slide rail 324 and forms a sliding connection. During operation, the moving module motor 341 drives the moving module connecting rod 342 to rotate, which in turn causes the moving module slider 343 to slide on the moving module crossbar slide rail 324, and drives the moving module crossbar 32 to move along the moving module slide rail 31. The moving module crossbar slide rail 324 is bolted to the moving module crossbar 32, and the moving module slide rail 31 is fixed to the frame 1 by bolts.

[0040] The crossbar connector 322 includes a base plate 3221, side plates 3222, and a back plate 3223. The base plate 3221 and the back plate 3223 are perpendicularly fixed together. The side plates 3222 are triangular plate structures, and there are two side plates 3222. The two right-angled sides of each side plate 3222 are fixedly connected to the base plate 3221 and the back plate 3223, respectively. The base plate 3221 is fixedly connected to the slider 323 by bolts, and the back plate 3223 is fixedly connected to the crossbar of the moving module 32 by bolts.

[0041] The crossbar connector slider 323 is a concave block structure. The crossbar connector slider 323 is locked on the sliding rail 31 of the moving module and forms a sliding connection.

[0042] The second lifting device 43 is a linear motor, and there are two second lifting devices 43 arranged in parallel.

[0043] In use, the seedling tray to be sown is transported to the lifting platform 44 by the push plate 33, and then the lifting platform 44 is lifted upward to the sowing position by the first lifting device 41 and the second lifting device 43. After the existing soil covering and sowing operations, the lifting platform 44 is lowered and placed on the lifting frame guide rod 422 by the first lifting device 41 and the second lifting device 43. The seedling tray moves to the corresponding position along the lifting frame guide rod 422.
