Description

Technical Field

[0001] This utility model relates to the field of seedling rack technology, and in particular to a three-dimensional planting rack with multi-stage transmission. Background Technology

[0002] Seedling racks are important tools for planting and cultivating seedlings. They can be configured with multiple layers to increase the number of seedlings, or they can be configured with a rotating structure to facilitate intelligent management of seedlings.

[0003] Most existing rotating planting racks are designed for independent use, with multiple layers of rotatable seedling trays between the racks. An independent power unit is installed on the outside of the rack to drive the rotation of the seedling trays.

[0004] The power unit of the above-mentioned planting rack cannot share power with other rotating planting racks with the same structure, so each set of rotating planting racks needs to have its own power unit, which increases the installation and operating costs of the equipment.

[0005] Secondly, since the planting racks are all rotating, manual balance control is required when loading and unloading seedling trays, and they can only be rotated after they are stable. This is inconvenient for daily observation and handling of seedling trays.

[0006] To address the aforementioned issues, a three-dimensional planting rack with multi-stage transmission is proposed. Utility Model Content

[0007] The main purpose of this invention is to provide a three-dimensional planting rack with multi-stage transmission, which solves the problems mentioned in the background art.

[0008] The objective of this utility model can be achieved by adopting the following technical solution:

[0009] A multi-stage transmission three-dimensional planting rack includes a support frame, on which columns are fixed by bolts to the inner sidewall of the support frame. A drive sprocket and a driven sprocket are rotatably mounted at both ends of the columns via bearings. A drive chain belt and a driven chain belt are respectively fitted onto the drive sprocket and the driven sprocket. A gearbox is fitted to the outer side of the drive sprocket, and a motor is fitted to the input end of the gearbox.

[0010] A drive shaft is also fixed between the driving sprocket and the driven sprocket.

[0011] Furthermore, there are two sets of drive shafts, which penetrate the top and bottom of the column and are rotatably mounted via bearings.

[0012] Furthermore, the number of support frames is several, and one group of support frames has identical columns symmetrically fixed on its outer side wall, with a secondary transmission part provided on the column.

[0013] Furthermore, the secondary transmission unit consists of a sprocket and a chain belt.

[0014] Furthermore, a second rotating pin is welded to the inner wall of the driving chain and the driven chain, and a hook is rotatably mounted on the second rotating pin.

[0015] Furthermore, the end of the hook furthest from the second rotating pin is rotatably connected to the first rotating pin.

[0016] Furthermore, a handle is fixed to the first rotating pin, a track is welded to the inner side of the handle, and a seedling tray is slidably limited on one side of the track, and the number of seedling trays is several.

[0017] Furthermore, rotating pins are symmetrically and rotatably installed on both outer walls of the seedling tray. The rotating pins are engaged with pin holes on the outer wall of the track. A control box that is detachably connected to the support frame is provided directly above the motor.

[0018] Furthermore, the track is provided with through-hole locking holes, and the top of the support frame is slidably connected to a locking shaft, which is inserted into the locking hole.

[0019] The beneficial technical effects of this utility model are as follows:

[0020] This utility model designs a multi-stage transmission three-dimensional planting rack. It uses a power assembly consisting of a single motor and a gearbox to drive the primary transmission unit, which consists of a drive sprocket, a drive chain, a drive shaft, a driven sprocket, and a driven chain, to rotate. This drives the seedling trays to rotate. At the same time, the power is transmitted to the secondary transmission units with the same structure as the primary transmission unit on the adjacent racks through the drive shaft. This drives the seedling trays on the adjacent planting racks to rotate synchronously. In this way, the purpose of multi-stage transmission is achieved, power sharing is realized, and the installation and use costs of the planting rack are reduced.

[0021] This invention features a track groove on the planting rack panel, with a slide rail installed within the groove. The slide rail is fixedly connected to the external hanging handle of the planting rack, allowing the rack panel to slide along the slide rail. When it is necessary to observe or load / unload seedlings, a locking pin is inserted into a locking hole to lock the track, facilitating the rack panel's sliding out. Simultaneously, the hanging handle is locked to prevent the rack panel from rotating. This design allows for stable operation by the user and is beneficial for loading / unloading seedling pots and daily inspection and observation of seedlings. Attached Figure Description

Detailed Implementation

[0031] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.

[0032] like Figures 1-7As shown, this embodiment provides a multi-stage transmission three-dimensional planting rack, including a support frame 1. A column 5 is fixed to the inner wall of the support frame 1 by bolts. A drive sprocket 6 and a driven sprocket 8 are rotatably mounted on both ends of the column 5 through bearings. A drive chain belt 7 and a driven chain belt 16 are respectively fitted on the drive sprocket 6 and the driven sprocket 8. A gearbox 2 is installed on the outer side of the drive sprocket 6. A motor 3 is installed on the input end of the gearbox 2. A drive shaft 13 is also fixed through and fixed between the drive sprocket 6 and the driven sprocket 8.

[0033] In the above structure, the driving chain 7 drives two sets of driving sprockets 6 to rotate synchronously. The driving sprockets 6 drive two sets of driven sprockets 8 to rotate synchronously via two sets of transmission shafts 13, thereby achieving the purpose of even power distribution.

[0034] There are two sets of drive shafts 13, which pass through the top and bottom of the column 5 and are rotatably mounted by bearings. When the drive shafts 13 transmit power in multiple stages, they can be connected to the secondary power unit through a coupling.

[0035] There are several support frames 1. On the outer side wall of one set of support frames 1, there are identical columns 5. A secondary transmission part 12 is provided on the column 5. When there is a multi-stage frame transmission, two sets of columns 5 are provided on the left and right sides of the support frame 1 located in the middle part, so as to facilitate the connection of the transmission shaft 13 through the secondary transmission part 12 to achieve the purpose of transmitting kinetic energy.

[0036] The secondary transmission unit 12 consists of a sprocket and a chain belt. The drive shaft 13 in the secondary transmission unit 12 is connected to the extension end of the drive shaft 13 in the primary transmission unit through a coupling to realize power transmission. It is also easy to disassemble and is conducive to the use of single or multiple planting racks. The sprocket and chain belt of the secondary transmission unit 12 have the same structure as the drive sprocket 6, drive chain belt 7, drive sprocket and driven chain belt 16 of the primary transmission unit, which facilitates the matching and installation of components of the same model.

[0037] A second rotating pin 15 is welded to the inner wall of the driving chain 7 and the driven chain 16. A hook 10 is rotatably mounted on the second rotating pin 15. A first rotating pin 14 is rotatably connected to the end of the hook 10 away from the second rotating pin 15. A handle 11 is fixed to the first rotating pin 14. A track 17 is welded to the inner side of the handle 11. A seedling tray 9 is slidably limited on one side of the track 17. There are several seedling trays 9, and the distance between the seedling tray 9 and the drive shaft 13 is 20-30 cm.

[0038] In the above structure, when the driven chain 16 and the driving chain 7 move the hook 10 to the top and bottom, the hinge action of the first rotating pin 14 and the second rotating pin 15 keeps the hook 10 hanging the seedling tray 9 downwards, ensuring that the surface of the seedling tray 9 always faces upwards and preventing it from tipping over. Sliding grooves are provided on the outer walls of two sides of the seedling tray 9, allowing it to slide in and out along the track 17.

[0039] Rotating pins 20 are symmetrically installed on the outer walls of both sides of the seedling tray 9. The rotating pins 20 are engaged with the pin holes on the outer wall of the track 17. A control box 4, which is detachably connected to the support frame 1, is set directly above the motor 3. In order to prevent the seedling tray 9 from sliding along the track 17 at will, the rotating pins 20 can limit the two sides of the seedling tray 9 to prevent it from sliding off the track 17 when it is tilted. When it is necessary to remove the seedling tray 9, the rotating pins 20 on both sides are opened. The control box 4, which is detachably connected to the support frame 1, is set directly above the motor 3. The control box 4 is used to provide power and control to the device. The output power of the motor 3 and the output torque of the gearbox 2 should drive an appropriate number of frame rotations within the rated range to avoid overloading the motor 3 and damaging the equipment.

[0040] The track 17 is also provided with through-holes 18. The top of the support frame 1 is slidably connected to a locking shaft 19. The locking shaft 19 is inserted into the locking hole 18. This setting is so that after the equipment stops, the locking shaft 19 is rotated to align with the locking hole 18. After the locking shaft 19 is inserted, it can limit the track 17 in conjunction with the hanging handle 11 to prevent it from tilting to the sides. Then, the rotating pins 20 at the four corners of the seedling tray 9 can be opened to slide the seedling tray out along the slide rail 7.

[0041] The working principle of this device is as follows:

[0042] When in use, this device is connected to an external power source and is intelligently controlled by control box 4.

[0043] The motor 3 outputs power after being reduced by the gearbox 2, which drives the bottom drive sprocket 6 to rotate. The drive sprocket 6 is driven by the drive chain belt 7 to rotate the top drive sprocket 6 of the column 5. The two sets of drive sprockets 6 drive the central transmission shaft 13 to rotate, which drives the driven sprocket 8 and driven chain belt 16 located at the other end of the transmission shaft 13 to rotate synchronously, so that the seedling tray 9 suspended between the inner wall of the driven chain belt 16 and the drive chain belt 7 can rotate at a uniform speed.

[0044] The secondary transmission unit 12, which is rotatably mounted on the column 5 on the other side of the driven sprocket 8, extends through the column 5 via the transmission shaft 13 to the sprocket of the secondary transmission unit 12. Then, through the transmission of the chain belt, it continues to drive the seedling trays 9 in the adjacent frame to rotate. In this way, according to the power range of the motor 3 and the gearbox 2, the transmission shaft 13 is extended to the next level frame, so that the synchronous rotation of multiple frames can be achieved.

[0045] By adopting the above structure, power can be shared between adjacent planting racks, achieving the purpose of multi-stage transmission and reducing the installation and operating costs of power equipment.

Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed by this utility model, based on the technical solution and concept of this utility model, shall fall within the protection scope of this utility model.
