Description

Technical Field

[0001] This utility model relates to a seedling raising device, and more particularly to a tray. Background Technology

[0002] Seedling cultivation is the process of raising seedlings. It is a labor-intensive, time-consuming, and technically demanding task. Previously, seedling cultivation was done manually by experienced staff. This method of seedling cultivation is inefficient and cannot meet the needs of large-scale, high-volume seedling production.

[0003] Current seedling cultivation methods generally employ mechanized sowing in factories, followed by placing the sown seedling trays in greenhouses or outdoor cement fields / seedbeds for germination and seedling cultivation. The materials used to manufacture these seedling trays typically include polystyrene foam, polystyrene, polyvinyl chloride, and polypropylene, and manufacturing methods include blow molding and injection molding. Commonly used seedling trays for vegetables and ornamental plants are made of polystyrene. In practice, multiple seedling trays can be placed on the same pallet.

[0004] The primary function of tray design is to support the seedling trays, and secondly, to facilitate handling, especially in mechanized seedling management. Utility Model Content

[0005] This utility model provides a tray that solves the problem of tray structure design for supporting caulking trays. The technical solution is as follows:

[0006] A pallet includes a metal frame, crossbeams, reinforcing bars, and load-bearing screws. The metal frame includes a horizontal frame and a vertical frame. A plurality of crossbeams parallel to the horizontal frame are arranged in the middle of the metal frame. Reinforcing bars are arranged between the crossbeams and the horizontal frame, and between the crossbeams. Load-bearing screws are arranged on the side of the vertical frame.

[0007] The metal frame includes two horizontal frames and two vertical frames, namely a first horizontal frame, a second horizontal frame, a first vertical frame, and a second vertical frame, which are connected end to end in sequence.

[0008] The metal frame is provided with a first crossbeam and a second crossbeam. The first crossbeam and the second crossbeam are parallel to the horizontal frame of the metal frame. The two ends of the first crossbeam and the second crossbeam are fixedly connected to the two vertical frames, respectively.

[0009] A longitudinally arranged first reinforcing bar is provided between the first crossbeam and the first cross frame, and between the second crossbeam and the second cross frame.

[0010] Between the first horizontal frame and the second horizontal frame, a second reinforcing bar is arranged longitudinally, and the number of the second reinforcing bars is less than that of the first reinforcing bar.

[0011] Multiple load-bearing screws are provided on the side of the vertical frame.

[0012] Two bearing screws are provided on the side of the vertical frame, and the bearing screws of the two vertical frames are symmetrically positioned.

[0013] The bearing screw is painted red.

[0014] The side of the longitudinal frame is provided with screw holes for screwing in threaded load-bearing screws.

[0015] The pallet, with its rectangular structure design, offers superior load-bearing and mobility. This invention boasts the following advantages: (1) the crossbeam design provides reinforcement; (2) the reinforcing rods enhance the pallet's structural strength and also divide the pallet into sections; (3) the track-mounted logistics robot can lift or lower the pallet using the side-mounted screws, simplifying operation; and (4) the brightly colored screws facilitate identification by the track-mounted logistics robot. This invention features a simple, robust, and durable structure, making it convenient for transportation and storage. Attached Figure Description

[0017] Figure 2 This is a structural schematic diagram of the track-mounted logistics robot. Detailed Implementation

[0018] like Figure 1 As shown, the pallet includes a metal frame, crossbeams, reinforcing bars, and load-bearing screws. The metal frame includes a horizontal frame and a vertical frame. Multiple crossbeams parallel to the horizontal frame are provided in the middle of the metal frame. Reinforcing bars are provided between the crossbeams and the horizontal frame, and between the crossbeams. Load-bearing screws are provided on the side of the vertical frame.

[0019] The metal frame includes two horizontal borders and two vertical borders, which are connected sequentially to form a rectangular metal frame. Specifically, the horizontal borders include a first horizontal frame 1 and a second horizontal frame 2, and the vertical borders include a first vertical frame 3 and a second vertical frame 4. The first horizontal frame 1, the first vertical frame 3, the second horizontal frame 2, and the second vertical frame 4 are connected end to end to form a rectangular metal frame.

[0020] In this embodiment, the metal frame has two crossbeams inside, namely a first crossbeam 5 and a second crossbeam 6. The first crossbeam 5 and the second crossbeam 6 are parallel to the horizontal frame of the metal frame. The first crossbeam 5 is closer to the side of the first horizontal frame 1, and the second crossbeam 6 is closer to the side of the second horizontal frame 2. Both ends of the first crossbeam 5 and the second crossbeam 6 are connected to the first vertical frame 3 and the second vertical frame 4.

[0021] A longitudinally arranged first reinforcing rod 7 is provided between the first crossbeam 5 and the first cross frame 1, and between the second crossbeam 6 and the second cross frame 2; a longitudinally arranged second reinforcing rod 8 is provided between the first cross frame 1 and the second cross frame 2, and the number of the second reinforcing rod 8 is less than the number of the first reinforcing rod 7.

[0022] Multiple support screws are provided on the sides of the vertical frame. In this embodiment, two support screws are provided on the sides of each vertical frame. The first vertical frame 3 has a first screw 9 and a second screw 10 on its side, and the second vertical frame 4 has a third screw 11 and a fourth screw 12 on its side. Furthermore, the screws on the two vertical frames are symmetrically arranged; the first screw 9 and the third screw 11 are symmetrically arranged, as are the second screw 10 and the fourth screw 12. The first screw 9 and the second screw 10 are located on either side of the middle of the first vertical frame 3, and the third screw 11 and the fourth screw 12 are located on either side of the middle of the second vertical frame 4. Thus, the tray can be smoothly lifted or lowered using these four support screws.

[0023] The interior of the metal frame is divided into multiple sections by crossbeams and reinforcing rods, each section accommodating abortion trays of different sizes. Alternatively, the sections can be designed to be the same size, allowing for the placement of trays of identical dimensions. Furthermore, a support plate or mesh 13 can be fixedly installed at the bottom of the metal frame to further support the abortion trays.

[0024] In use, the bearing screws of this utility model are painted red, and the bright color makes them easy for the track-mounted logistics robot 16 to identify. The structure of the track-mounted logistics robot 16 is as follows: Figure 2 As shown, a lifting device 14 and a color counting device (not shown) are arranged on both sides. The color counting device is equipped with a color sensor to read the red color of the supporting screws. The lifting device 14 is equipped with a hook 15. When the track-mounted logistics robot 16 moves along the track, the color counting device reads the number of supporting screws to identify the destination pallet to be transported. Then, the lifting device 14 drives the hook 15 to fall, and then moves forward so that the hook 15 is below the supporting screws. The lifting device 14 then drives the hook 15 to rise, thereby lifting the pallet. The falling and rising steps are the reverse of each other.

[0025] This invention features a rectangular structure that provides better load-bearing and mobility. The crossbeams and reinforcing bars increase the pallet's sturdiness and also divide the pallet into sections. The brightly colored load-bearing screws facilitate identification by track-mounted logistics robots, enabling lifting and lowering. This invention is simple in structure, robust and durable, and easy to transport and store.
