Description

Technical Field

[0001] The utility model relates to the technical field of transfer frames, in particular to a seedling tray transfer frame. Background Art

[0002] Seedling trays, also called plug trays, have become an important tool in the factory seedling production process. Whether it is flowers or vegetables, plug tray seedling cultivation is the most fundamental change in modern horticulture, providing a guarantee for fast and mass production. The materials used to make plug trays are generally polystyrene foam, polystyrene, polyvinyl chloride and polypropylene. The manufacturing methods include blow molding and injection molding. General vegetable and ornamental plant seedling plug trays are made of polystyrene.

[0003] During the greenhouse seedling raising process, the germination, sowing and transplanting stages require the materials (hole trays and substrates) to be transported between different areas.

[0004] In order to increase the number of items that can be placed, existing transfer frames generally use multiple partitions installed at equal intervals in the longitudinal direction to stack items at high places. However, due to the different manufacturing materials of the seedling trays, the weight increases when the soil or matrix is ​​filled inside, and some plastic seedling trays may be deformed and spilled during transportation. Therefore, how to place the seedling trays stably on a high level when stacking them is a difficult problem that needs to be solved. In addition, the spacing between the partitions of existing frames is mostly fixed, and the height cannot be adjusted accordingly according to the actual size of the object, which has certain limitations.

[0005] Currently, no effective solution has been proposed for the problems in the related technologies. Utility Model Content

[0029] To further illustrate each embodiment, the present invention provides drawings, which are part of the disclosure of the present invention and are mainly used to illustrate the embodiments. They can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, ordinary technicians in the field should be able to understand other possible implementation methods and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0030] According to an embodiment of the utility model, a seedling tray transport frame is provided.

[0031] The present invention is now further described in conjunction with the accompanying drawings and specific implementation methods. Figure 1-6As shown, a seedling tray transport frame according to an embodiment of the utility model includes a base 3, support plates 4 are symmetrically arranged on both sides of the top of the base 3, screw rods 8 and sliding rods are respectively arranged in the middle position inside the support plates 4, one end of the screw rod 8 passes through the base 3 and is connected to the motor 14, threaded rods 5 are sleeved on the screw rods 8 and the sliding rods, and a lifting frame 12 is connected between the threaded rods 5, and a placing plate 11 is placed on the lifting frame 12, and a plurality of groups of support frames 6 are symmetrically arranged on the opposite side surface of the support plate 4 and on both sides of the screw rod 8 and the sliding rod, A fixed plate 7 is rotatably connected inside the support frame 6, a partition 13 is provided inside the base 3, a cylinder 16 is provided in the middle position of the top of the partition 13, a rope connecting plate 15 is fixedly connected to the top of the cylinder 16, a plate placement groove 2 is provided below the partition 13, and the length of the lifting frame 12 is shorter than the length of the placement plate 11. Therefore, when the fixed plate 7 is horizontally unfolded, the longer placement plate 11 will fall above the fixed plate 7, while the shorter lifting frame 12 will be freely lifted and lowered without hindrance, thereby fixing the placement plate 11 on the fixed plate 7.

[0032] In one embodiment, a trapezoidal block 17 is provided on the top of the lifting frame 12, and a corresponding number of limiting grooves 20 are provided on the bottom of the placing plate 11, and the trapezoidal block 17 is located in the limiting groove 20. Plug holes 19 are provided around the bottom of the placing plate 11, and a shift rod 18 is fixedly connected to the front and rear sides of the top of the placing plate 11. The trapezoidal block 17 is set to be trapezoidal in order to make the separation of the placing plate 11 and the lifting frame 12 easier while playing a limiting role.

[0033] In one embodiment, a torsion spring 22 is connected between the support frame 6 and the fixed plate 7, a latch 23 is provided on the top surface of the fixed plate 7, and a rope hole 21 is provided at the top position of one side of the fixed plate 7. The torsion spring 22 causes the fixed plate 7 to be in an upward position under normal conditions under torsion, thereby providing a channel for the placement plate 11 to rise.

[0034] In one embodiment, the rope holes 21 provided on the upper and lower adjacent fixing plates 7 are connected by a pull rope 9, and the pull rope 9 is in a taut state when connected. The taut connection is to enable the pull rope 9 to move immediately when the rope connecting plate 15 moves, thereby pulling the fixing plate 7 to unfold.

[0035] In one embodiment, one end of the pull rope 9 passes through the base 3 and is connected to the top of the rope connecting plate 15. The pull rope 9 connected to the top is pulled to move by lifting and lowering the rope connecting plate 15.

[0036] In one embodiment, moving wheels 1 are installed around the bottom of the base 3 .

[0037] In one embodiment, a reinforcement rod 10 is connected to the top end of the support plates 4 to provide reinforcement and prevent the support plates 4 on both sides from tilting.

[0038] In one embodiment, due to the structural design, the devices can only be placed from high to low, and removed from low to high.

[0039] Working principle: In actual use, when the seedling tray needs to be stacked, first take out the corresponding number of placement plates 11 from the plate placement slot 2, and then place the placement plates 11 on the lifting frame 12, so that the trapezoidal block 17 provided on the top of the lifting frame 12 is inserted into the limiting groove 20 at the bottom of the placement plate 11, so as to limit the placement plate 11 to prevent the placement plate 11 from moving during the lifting process, and ensure that the latch 23 on the fixed plate 7 and the socket 19 at the bottom of the placement plate 11 can always overlap together. After limiting, place the seedling tray on the placement plate 11, and then start the motor 14. The rotation of the motor 14 drives the screw rod 8 to rotate, and the rotation of the screw rod 8 drives the threaded rod 5 to move, so that the lifting frame 12 and the placement plate 11 move upward. When it moves to the top of the fixed plate 7 at the highest point, the telescopic cylinder 16 drives the rope receiving plate 15 to descend, and the rope receiving plate 15 descends to pull the surrounding pull ropes 9, thereby the fixed plate 7 The lifting frame 12 and the placing plate 11 are then reversed to move the lifting frame 12 and the placing plate 11 downward. Due to the horizontal expansion of the fixing plate 7, when the placing plate 11 descends, it will land on the surface of the fixing plate 7 and be limited by the limiting groove 20 and the trapezoidal block 17 to ensure that the pin 23 on the surface of the fixing plate 7 is inserted into the socket 19 at the bottom of the placing plate 11 to fix the placing plate 11. Then, the lifting cylinder 16 resets the rope connecting plate 15. At this time, the remaining empty fixing plates 7 will be retracted upward under the action of the torsion spring 22 to provide a channel for the subsequent lifting of the lifting frame 12 and the placing plate 11. In this way, multiple seedling trays can be stacked on the frame from high to low in sequence, and the spacing between the placing plates 11 can also be adjusted according to the actual height of the seedling trays. The frame as a whole has the advantages of simple and convenient stacking, avoiding soil matrix spillage, and flexible use.
