Abstract
Description
Technical Field
[0001] This utility model relates to a tobacco seedling transplanting device to prevent damage to tobacco seedlings, belonging to the technical field of tobacco leaf transportation devices. Background Technology
[0002] Tobacco seedling tray technology is currently a relatively advanced seedling cultivation method both domestically and internationally. It offers advantages such as convenient intensive management, high-quality seedlings, and resource conservation. However, foam seedling trays are bulky, inconvenient to transport and store, and have high costs and transportation expenses. During transportation, to improve efficiency, the trays are often stacked, which can easily damage the tobacco leaves and roots, affecting the survival rate. Patent document CN 107996203 A discloses a detachable tobacco-raising frame, consisting of a tobacco-raising frame, connecting strips, and bolts and nuts. The connecting strips assemble multiple layers of the tobacco-raising frame together. The tobacco-raising frame consists of four long rods and two short rods, with a round hole at each end of the long rods on the side. The upper end of the connecting strip has a rope-tying hole, and the middle of the connecting strip has multiple equally spaced round holes of the same size, which can be inserted into the bolts and nuts to assemble the multiple layers of the tobacco-raising frame together. The seedling trays are placed on the tobacco rack, one tray of seedlings per layer. This ensures the roots and stems of the seedlings are not damaged, improving both the survival rate and transportation efficiency. However, the height of each layer of the tobacco rack is not adjustable. For healthy seedlings, insufficient rack height can still damage them, while for weaker seedlings, excessively high rack height can take up space, reducing the amount of tobacco that can be loaded and resulting in low transportation efficiency. Utility Model Content
[0003] Therefore, the purpose of this utility model is to provide a tobacco seedling transplanting device to prevent damage to tobacco seedlings, so as to at least solve the problems mentioned in the background art.
[0004] The objective of this utility model is achieved through the following technical solution:
[0005] A tobacco seedling transplanting device for preventing damage to tobacco seedlings includes a first frame, and several layers of second frames are provided on the top of the first frame. The second frames are detachably connected to the first frame through a height adjustment device.
[0006] Furthermore, both the first frame and the second frame are square basket structures composed of a tray and baffles on each side of the tray. The center of the square basket structure is a placement cavity corresponding to the size of the seedling tray. Slot structures are provided at the four corners of the top surface of the first frame and the second frame. The height adjustment device is located at the bottom of the second frame, and the height adjustment device is provided with insertion feet corresponding to the slot structures, so that the second frame is inserted and fixed to the first frame through the height adjustment device.
[0007] Furthermore, multiple fixing rings are symmetrically arranged on the outer sides of the two opposing baffles of the first frame, and ropes are provided on the fixing rings.
[0008] Furthermore, handles are symmetrically provided on the outer sides of the two opposing baffles of the second frame; the handles are positioned opposite the fixing rings, and after the ropes are fixed to the fixing rings, they pass through the handles of each layer of the second frame sequentially from bottom to top.

[0029] Example 1
[0030] like Figures 1-3 As shown, a tobacco seedling transplanting device for preventing damage to tobacco seedlings includes a first frame 1, and several layers of second frames 2 are provided on the top of the first frame. The second frames 2 are detachably connected to the first frame 1 through a height adjustment device 3.
[0031] Both the first frame 1 and the second frame 2 are square basket structures composed of a tray and baffles on each side of the tray. The center of the square basket structure is a placement cavity corresponding to the size of the seedling tray. Slot structures 4 are provided at the four corners of the top surface of the first frame 1 and the second frame 2. The height adjustment device 3 is located at the bottom of the second frame 2, and the height adjustment device 3 is provided with insertion feet 5 corresponding to the slot structures 4, so that the second frame 2 is inserted and fixed to the first frame 1 through the height adjustment device 3.
[0032] Multiple fixing rings 6 are symmetrically arranged on the outer sides of the two opposite baffles of the first frame 1, and ropes 7 are provided on the fixing rings 6. The ropes facilitate the transport of the first frame 1 and several layers of second frames 2 on the top of the first frame together.
[0033] Handles 8 are symmetrically provided on the outer sides of the two opposite baffles of the second frame 2 to facilitate the lifting and lowering of the second frame 2. Preferably, the handles 8 are positioned opposite the fixing rings 6, and the ropes 7 are fixed to the fixing rings 6 and pass through the handles on each layer of the second frame 2 from bottom to top, which can further ensure the stability of the overall structure.
[0034] Multiple notches 9 extending to the tray are provided on the sides of the baffles on both sides of the first frame 1 and the second frame 2. These notches 9 facilitate the lifting and placing of the seedling tray and can also reduce the weight of the first frame 1 and the second frame 2.
[0035] The first frame 1 and the second frame 2 are square basket structures made of lightweight plastic and aluminum, making them easy to carry and transport.
[0036] In this embodiment, the height adjustment device 3 includes threaded sleeves 301 located at the four corners of the bottom of the second frame 2 and opposite to the slot structure 4. A screw 302 is screwed into the threaded sleeve 301, and the insertion pin 5 is located at the bottom end of the screw 302. The height of the second frame 2 can be adjusted by adjusting the screw 302.
[0037] Example 2:
[0038] like Figure 4 As shown, based on Embodiment 1, the height adjustment device 3 includes a first sliding sleeve 303 located at the four corners of the bottom of the second frame 2. A telescopic rod 304 is slidably connected within the first sliding sleeve 303, and the two telescopic rods 304 are connected by a connecting rod 305. The insertion pin 5 is located at the bottom end of the connecting rod 305 and is positioned opposite to the slot structure 4. A limiting ball 306 is provided on the outside of the first sliding sleeve 303 to limit the extension and retraction of the telescopic rod 304. By controlling the extension and retraction of the telescopic rod 304 through the limiting ball 306, the height of the second frame 2 can be adjusted.
[0039] Example 3:
[0040] like Figures 5-8 As shown, based on embodiments 1 and 2, the height adjustment device 3 can also be a rack and pinion transmission mechanism. The rack and pinion transmission mechanism includes a second sliding sleeve 307 symmetrically arranged at the midpoint of two opposite sides of the bottom of the second frame 2. A rack 308 and a gear 309 meshing with the rack 308 are slidably connected within the second sliding sleeve 307. A support rod 310 is provided at the bottom of the rack 308. The insertion foot 5 is located at the bottom end of the support rod 310 and is positioned opposite to the slot structure 4. Specifically, a slide rail 311 is provided on one side of the second sliding sleeve 307. The rack 308 is mounted on the slide rail 311 and slidably connected thereto. A gear frame 312 is provided on the side of the second sliding sleeve away from the slide rail. The gear 309 is mounted on the gear frame 312 and meshes with the rack 308. A limiting pin 313 is provided on the gear frame 312 to limit the rotation of the gear 309. In use, pull out the limit pin 313 to make the gear 309 rotate, which in turn drives the rack 308 to move. Adjust the height of the second frame 2. After adjustment, insert the limit pin 313 again to limit the rotation of the gear 309.
