[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0020] like Figures 1 to 5As shown, a sweet potato seedling gathering device includes a storage compartment 1. Four support columns 2 are installed at the upper edge of the storage compartment 1. A top plate 3 is installed at the upper end of each support column 2. A groove 5, which is circular, is formed at the center of the upper end of the top plate 3. Seedling holes 7 are formed at the edge of the groove 5. The seedling holes 7 are relatively large, allowing sweet potato seedlings to pass through easily. A protective shell 10 is installed below the seedling holes 7 and at the lower end of the top plate 3. The center of the protective shell 10 is on the same vertical line as the seedling holes 7, allowing the sweet potato seedlings to enter the protective shell through the seedling holes 7. Inside the protective shell 10, a funnel-shaped chamber 15 is installed at the lower end of the protective shell 10. A connecting frame 16 is installed at the lower end of the funnel-shaped chamber 15. A bottom frame 17 is connected to the lower end of the connecting frame 16 via multiple rods. A rotating plate 18 is rotatably connected inside the bottom frame 17. A drive device, which is a common servo motor, is installed inside the bottom frame 17. The output end of the drive device is connected to the rotating plate 18 via a rotating shaft. The drive device can drive the rotating plate 18 to rotate. Four electric motors are installed in a rectangular array at the lower edge of the connecting frame 16. The push rod 19 is an electric push rod controlled by a travel control switch. A fixing plate 20 is installed on each of the four outer side walls of the connecting frame 16. The fixing plates 20 and the electric push rods 19 are vertically arranged and on the same vertical line, with a certain distance between them. Elastic ropes are installed on the exterior of all four electric push rods 19. Multiple locking slots 21 are provided on the side of the fixing plates 20 facing the electric push rods 19. Multiple elastic ropes are installed on the exterior of all four electric push rods 19, and these elastic ropes are sequentially locked into the locking slots 21. The weight sensor at the top of the rotating plate 18 controls the four electric push rods 19 to retract upwards to the position of the locking groove 21. At this time, the elastic rope at the bottom of the electric push rod 19, which was limited by the locking groove 21, will lose its limitation and retract elastically, thus binding multiple sweet potato seedlings. Meanwhile, the rotating plate 18 will slowly rotate downwards in a short time, and the bound sweet potato seedlings will fall into the storage compartment 1. Finally, the bound sweet potato seedlings can be manually adjusted in position inside the storage compartment 1 to complete the sorting and storage of the sweet potato seedlings.
[0021] Specifically, a rotating disk 4 is installed inside the groove 5, and a driving device is installed inside the rotating disk 4. A rotating shaft 22 is installed at the output end of the driving device. Multiple connecting rods 8 are arranged on the side of the rotating shaft 22. A seedling chamber 9 is installed at the other end of the connecting rods 8. The size of the seedling chamber 9 is the same as the size of the seedling hole 7. The driving device can drive the rotating shaft 22 to rotate, and the rotating shaft 22 drives the multiple connecting rods 8 to rotate, which in turn drives the multiple seedling chambers 9 to rotate. The staff puts the cut sweet potato seedlings into any of the seedling chambers 9. As the seedling chamber 9 rotates, the sweet potato seedlings inside the seedling chamber 9 will overlap with the seedling hole 7. At this time, the sweet potato seedlings inside the seedling chamber 9 will fall out of the seedling hole 7.
[0022] Furthermore, the bottom of the storage compartment 1 is equipped with multiple casters 6, which can move the storage compartment 1 inside the greenhouse.
[0023] Furthermore, the protective shell 10 has a central rotating shaft 13 rotatably connected to the lower end of the top plate 3 inside, and a driving device connected to the upper end of the central rotating shaft 13 inside the top plate 3. Multiple partition plates 12 are arrayed on the side surface of the central rotating shaft 13, and a rotating ring 11 is installed on the outer side of the multiple partition plates 12. Two opening and closing doors 14 are rotatably connected to the lower end of the rotating ring 11. The multiple partition plates 12 divide the space of the rotating ring 11 into multiple spaces, each of which can hold a sweet potato seedling.
[0024] Furthermore, infrared sensors are installed on one side of each of the multiple partitions 12. These infrared sensors are electrically connected to the opening and closing door 14. A weight sensor is installed on the upper end of the rotating plate 18. The weight sensor is electrically connected to an external controller. The weight sensor is a weight sensor, and a Mettler IND331 can be selected. The external controller can be a Raspberry Pi with a Modbus TCP / IP library. The external controller is electrically connected to the four electric push rods 19. When the sweet potato seedlings enter the space between the two partitions 12, they will be detected by the infrared sensors on the side of the partitions 12. At this time, the infrared sensors will be electrically connected to the external controller. The external controller can control the drive device connected to the central rotating shaft 13. The drive device can drive the central rotating shaft 13 to rotate, thereby driving the partitions 12 to rotate. This moves the space of the partitions 12 containing the sweet potato seedlings to the outside of the seedling hole 7, making the lower end of the seedling hole 7 another placement space.
[0025] The usage method of this embodiment is as follows: The staff cutting sweet potato seedlings put the cut sweet potato seedlings into the seedling bin 9. During the rotation of the seedling bin 9, the sweet potato seedlings will enter the space between the two partition plates 12 through the seedling hole 7. When the space between the partition plates 12 is completely occupied by sweet potato seedlings, the opening and closing door 14 will open. At this time, multiple sweet potato seedlings will fall into the funnel bin 15 at the same time and contact the upper end of the rotating plate 18 of the bottom frame 17. The weight sensor at the upper end of the rotating plate 18 controls the four electric push rods 19 to retract upward to the position of the locking groove 21. At this time, the elastic rope at the bottom of the surface of the electric push rod 19, which was limited by the locking groove 21, will lose the limitation of the electric push rod 19 and retract elastically. At this time, multiple sweet potato seedlings will be tied together. At the same time, the rotating plate 18 will slowly rotate downward in a short time, and the tied sweet potato seedlings will fall into the storage bin 1. Finally, the tied sweet potato seedlings are manually adjusted in position inside the storage bin 1 to complete the sorting and storage of the sweet potato seedlings.
[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
