Description

Technical Field

[0001] The invention relates to the technical field of seedling transport trays, and in particular to a position-limited seedling transport tray for planting Chinese herbal medicines. Background Art

[0002] With the standardized development of the Chinese herbal medicine industry, the quality control requirements for the seedling transportation link are getting higher and higher. From the perspective of GAP (Good Agricultural Practice) in the cultivation of Chinese herbal medicines, it is necessary to ensure that the quality of the seedlings is not damaged during the transportation process to ensure the quality and efficacy of the final Chinese herbal medicines.

[0003] For the current transfer pallet, the existing limitable seedling transfer pallet for chrysanthemum planting disclosed by patent number "CN217779276U" is a kind of limitable seedling transfer pallet for chrysanthemum planting. By placing the chrysanthemum seedling planting pot in the placement groove, adjusting the length of the telescopic rod so that the clamping plate at its end can contact the chrysanthemum seedling planting pot, and then rotating the sleeve to clamp the chrysanthemum seedling planting pot, and then tightening the fastening bolt, the purpose of limiting can be achieved. After the seedlings are properly placed and fixed, this device directly places the entire device in the car. Once the road conditions are poor, it is very easy to cause bumps during the driving of the vehicle, making it difficult for the pallet to maintain a stable state in the car, and then sliding occurs. As the sliding amplitude increases and the bumps continue, the pallet will frequently hit the inner wall of the car, which may not only cause damage to the pallet itself, but also the violent impact and shaking may cause the fixing structure of the seedlings to loosen, and even cause the seedlings to fall off from the original fixed position, thereby causing damage to the seedlings.

A T-shaped groove is provided at the connection between the transfer plate body 15 and the seedling transfer plate 16, and a T-shaped block matching the T-shaped groove is provided on the seedling transfer plate 16. The cooperation between the T-shaped groove and the T-shaped block enables the seedling transfer plate 16 to slide smoothly in a specific direction inside the transfer plate body 15, while ensuring the stability of the connection between the two, thereby preventing the seedling transfer plate 16 from accidentally shifting during the transportation process.

[0025] A plurality of seedling placement plates 23 are fixedly connected to the opposite side of the pillar 6 and the support rod 61. A plurality of circular grooves are provided in the seedling placement plates 23. The circular grooves can be divided according to the type, size or growth stage of the seedlings. The inner wall and the bottom of the placement groove 17 are installed with rubber anti-skid pads, which are made of a special rubber material with high friction, good flexibility and durability. The rubber anti-skid pads on the inner wall increase the friction with the side of the seedling pot, and the rubber anti-skid pads at the bottom can reduce the impact of the seedling pot falling from the seedling transfer plate 16; It also includes an exhaust component, a driving component, a flipping component and a moving component. The flipping component is used to flip the connecting plate 13 to one side of the seedling placement plate 23. The flipping component includes a first gear 1301 and a first rack 1302. The first gear 1301 is fixedly connected to the rotating shaft 12, and the first rack 1302 is fixedly connected to the side wall of the support rod 61.

The second rack 1604 is symmetrically fixedly connected to the bottom surface of the seedling transfer plate 16, and the second gear 1603 and the second rack 1604 are meshed with each other.

[0027] In this embodiment, the bottom plate 1 is first placed inside the car, and the second motor 7 is started to drive the screw rod 8 to rotate. The nut 10 sleeved on the outside thereof then slides downward along the screw rod 8, and synchronously drives the slider 11 to slide downward along the slide rod 9 through the connecting plate 13, and drives the first gear 1301 on both sides of the slider 11 and the nut 10 to engage with the first rack 1302. The first gear 1301 is rotated under force and drives the connecting plate 13 to rotate, thereby flipping the transfer plate body 15 to a state parallel to the bottom plate 1. As the screw rod 8 continues to rotate, it drives the connecting plate 13 and the transfer plate body 15 to move down to the bottom surface of the car. At this time, the electric telescopic rod 14 is started to drive the transfer plate body 15 to rotate. The transport plate 15 moves down to the ground, and the staff then places the seedling pots to be transported on the seedling transport plate 16. When the placement is completed, the second motor 7 is started again to drive the screw rod 8 to rotate and drive the nut 10 and the transport plate 15 to rise to the side of the seedling placement plate 23. At the same time, the third motor 1601 is started to drive the drive shaft 1602 to rotate, and the second gear 1603 sleeved on its outside is immediately engaged with the adjacent second rack 1604. The second rack 1604 is driven by force to drive the seedling transport plate 16 to move forward to the seedling placement plate 23, and the seedling pots are placed on the seedling placement plate 23 in turn through the cooperation of the L-shaped block and the inclined block 27.

[0028] Embodiment 2:

[0029] Different from the first embodiment, Figure 5 , Figure 7 and Figure 8, this embodiment also has the following further contents: a placement groove 17 is symmetrically provided on the seedling transfer plate 16, a plurality of circular holes are provided on the seedling transfer plate 16, and are communicated with the placement groove 17. When the second clamping block is forced to move backward, the seedling pot will fall into the circular hole on the seedling placement plate 23 through the circular hole. A transverse plate 18 is fixedly connected to the inner wall of the placement groove 17, and a plurality of first clamping rings 19 are fixedly connected to the side wall of the transverse plate 18. A plurality of cavities are provided on the opposite sides of the placement groove 17, and a first spring 20 is fixedly connected to the inner walls of the plurality of cavities. A second clamping ring 21 is fixedly connected to one end of the first spring 20 away from the cavity, and a silicone pad is installed on the inner walls of the first clamping ring 19 and the second clamping ring 21, which has a certain flexibility and will not cause damage to the seedling pot while ensuring sufficient clamping force for the seedling.

[0030] The side wall of the second clamping ring 21 is fixedly connected with an L-shaped rod 22, and the L-shaped rod 22 is slidably connected to the cross plate 18, and the L-shaped rod 22 is slidably connected to the cavity. The top of the L-shaped rod 22 is arranged in an inclined surface. When the seedling transfer plate 16 moves toward the seedling placement plate 23, the L-shaped rod 22 on the seedling transfer plate 16 will come into contact with the inclined block 27. Under the action of the inclined surface, the L-shaped rod 22 will be subjected to a component force along the inclination direction of the inclined block 27. This component force will push the long plate 26 to slide in the fixed plate 24 and compress the second spring 25 at the same time. When the seedling transfer plate 16 is retracted, the L-shaped rod 22 will come into contact with the inclined block 27 again. At this time, the inclined block 27 will exert a reverse force on the L-shaped rod 22, so that the L-shaped rod 22 drives the second clamping ring 21 to move backward, thereby accurately placing the seedlings on the seedling placement plate 23.

[0031] The inner wall of the seedling placement plate 23 is fixedly connected to a fixing plate 24, which is hollow and has an internal space that provides a track for the sliding of the long plate 26. The inner wall of the fixing plate 24 is slidably connected to the long plate 26, and a side of the long plate 26 close to the fixing plate 24 is fixedly connected to a plurality of second springs 25, which are fixedly connected to the fixing plate 24, and a side of the long plate 26 away from the fixing plate 24 is fixedly connected to a plurality of inclined blocks 27.

[0032] In this embodiment, when the seedling pot contacts the second clamp ring 21, the second clamp ring 21 is forced to move backward and squeeze the first spring 20. When the placement is completed, the second clamp ring 21 is driven to reset under the action of the first spring 20, so that the seedling pot is clamped on the seedling transfer plate 16 to avoid shaking during the rising process, which may cause it to fall. When the moving component drives the seedling transfer plate 16 to move toward the seedling placement plate 23, one side of the L-shaped rod 22 contacts the inclined surface of the inclined block 27, thereby driving the long plate 26 to move. After that, the second spring 25 is squeezed backward. As the moving component pushes the seedling transfer plate 16 completely into the seedling placement plate 23, the seedling transfer plate 16 is reset and moved backward again by the moving component. When the inclined surface of the L-shaped rod 22 contacts the other surface of the inclined block 27, the L-shaped rod 22 is forced to move backward and drives the second clamp ring 21 to squeeze the first spring 20 backward, so that the seedling pots fall into the circular groove from the circular holes on the seedling transfer plate 16 in turn, thereby realizing the neat placement of the seedlings on the seedling placement plate 23.
