[0002] At present, most greenhouse flowers or plant seedlings need to be cultivated in seedbeds. After a period of use, some debris such as leaves, matrix soil, pathogens, and insect eggs will remain on the seedbeds, which will harm the healthy growth of the seedlings. Therefore, the seedbeds need to be cleaned regularly.

[0003] Before cleaning the seedbed, it is necessary to transport the seedbed and control the seedbed to reach the cleaning station. In the existing seedbed transportation, some are transported manually, which is labor-intensive and time-consuming, and the transportation cost is high. Some are transported mechanically, but in the actual transportation process, it is difficult to ensure that the cleaning and stacking of the seedbeds are consistent, which affects the cleaning efficiency of the seedbed. At the same time, the existing transportation equipment can transport fixed seedbed models, that is, different transportation equipment is required for the transportation of different seedbeds, so the applicability of the transportation equipment is poor. Utility Model Content

[0004] The purpose of the utility model is to overcome the existing seedling bed transportation in the prior art, in which a part of it adopts manual transportation, which is labor-intensive and time-consuming, and the transportation cost is high, and a part of it adopts mechanical transportation. However, in the actual transportation process, it is difficult to ensure that the cleaning and stacking of the seedling beds are consistent, which affects the cleaning efficiency of the seedling beds. At the same time, the existing transportation equipment can transport a fixed type of seedling bed, that is, different transportation equipment is required for the transportation of different seedling beds, so the applicability of the transportation equipment is poor. A light-load overhead crane for seedling bed transportation is provided. The light-load overhead crane is controlled by a PLC system, and can realize functions such as fixed-point stacking and horizontal transfer of the bed, system arrangement, etc. Therefore, it can cooperate with a seedling bed cleaning machine to complete cleaning, stacking and other tasks, which solves the tediousness of manual transportation and placement of the seedling beds, saves about 80% of the labor, and the device can be used to clamp different types of seedling beds, and the device has higher applicability.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

The clamping claw can clamp the seedbed. After clamping the seedbed, the lifting motor can drive the traction grab plate frame to rise in the vertical direction. When it is lifted to a suitable height, the walking frame walks along the preset track until it stops at the preset position. The lifting motor controls the grab plate frame to descend. After the seedbed is placed in the corresponding position, the clamping claw opens and the lifting motor controls the grab plate frame to reset, thus completing the transportation of the seedbed. In summary, the light-load overhead crane is controlled by the PLC system, which can realize functions such as fixed-point stacking and horizontal transfer of the bed and system arrangement.

When releasing the seedling bed, the locking device rotates again, and the locking hook rotates again. After the locking hook rotates to the outside of the seedling bed, the seedling bed can be released.

The grabbing frame 3 is arranged below the walking frame 6. A sling wheel 10 and a lifting motor 16 for driving the sling wheel 10 to rotate are also installed on the walking frame 6. The lower part of the sling wound around the sling wheel 10 is connected to the grabbing frame 3, so that the lifting motor 16 can pull the grabbing frame 3 to move in the vertical direction for lifting and lowering. The grabbing frame 3 is installed with a clamping claw 2 for grabbing the seedling bed.

[0026] By adopting the above technical solution:

[0027] When the light-load overhead crane is in use, first, the walking frame 6 in the light-load overhead crane is assembled on the top track of the seedbed processing workshop, and the walking frame 6 can walk on the track according to the preset trajectory, and the grabbing plate frame 3 is installed with a clamping claw 2, through which the seedbed can be clamped. After the clamping claw 2 clamps the seedbed, the grabbing plate frame 3 can be driven to rise in the vertical direction through the lifting motor 16. When it is lifted to a suitable height, the walking frame 6 walks along the preset track until it stops after walking to the preset position. The lifting motor 16 controls the grabbing plate frame 3 to descend, and after the seedbed is placed in the corresponding position, the clamping claw 2 opens, and the lifting motor 16 controls the grabbing plate frame 3 to reset, that is, the transportation of the seedbed is completed. In summary, the light-load overhead crane is controlled by the PLC system, and can realize the functions of fixed-point stacking horizontal transfer, system arrangement and the like of the bed. Therefore, it can cooperate with the seedbed cleaning machine to complete the cleaning, stacking and other tasks, which solves the cumbersomeness of manual transportation and placement of the seedbed and saves about 80% of the labor.

The clamping link group 5 is transmission-connected with the clamping claw 2. Four clamping claws 2 are provided, and the four clamping claws 2 are grouped in pairs. Two clamping claws 2 in the same group are rotatably installed on the grabbing disc frame 3 through a rotating shaft, and are transmission-connected through a transmission shaft.

A locking hook 1 is connected to the bottom of each locking device 14. The locking device 14 is used to lock the clamped seedling tray after the clamping claws 2 clamp the seedling tray to prevent it from falling and to ensure the stability and safety of the seedling bed during transportation. When in use, after the clamping claws 2 clamp the seedling tray, the locking device 14 rotates to rotate the locking hook 1 located below the locking device 14, and the locking hook 1 rotates to the corresponding slot on the seedling bed to achieve locking and fixing of the seedling bed. When releasing the seedling bed, the locking device 14 rotates again, and the locking hook 1 rotates again.

This makes it convenient to put away the locking hook 1. At the same time, it is convenient to clamp different types of seedling beds (different types of seedling beds have different structures). The locking hook 1 can adjust its height according to actual needs, thereby adjusting its locking position, thereby making the device more applicable.
