Description

Technical Field

[0001] This invention pertains to agricultural machinery and equipment, and mainly relates to a rice seedling tray separator. Background Technology

[0002] Heilongjiang Province, as a major rice-producing base in my country, has a rice planting area of ​​3.813 million hectares and an annual rice production of approximately 27 million tons, ranking first in the country in total output. Rice grown in Heilongjiang Province is characterized by superior quality, high yield, high marketability, and high economic benefits, possessing significant development advantages and potential. Full mechanization of rice production is a crucial means to ensure the stable development and improvement of the rice industry. The main mechanized rice production process includes straw processing, land preparation, seedling raising, transplanting, plant protection, harvesting, and drying. However, the mechanization level of the rice seedling tray separation stage between seedling raising and transplanting is relatively weak compared to other stages, still requiring a significant amount of manual labor, resulting in high labor intensity and production costs. The patent application, with publication number CN 211520611 U and titled "Integrated Machine for Lifting and Collecting Rice Seedling Trays in Greenhouses," addresses the issues of high labor intensity, large manpower requirements, and high production costs. However, it still has some drawbacks. First, the device involves two sets of conveyor systems working together, making its design relatively complex and resulting in a higher failure rate. Second, in practical use, the device is primarily designed for lifting, separating, and collecting seedlings using plastic hard disks. However, it is not effective at separating seedlings using plastic floppy disks, and may even fail to achieve the desired separation, potentially damaging the seedlings and substrate and causing inconvenience to subsequent work.

The tray collecting mechanism is higher than the square frame and placed inside the square frame, and the base 11 of the tray collecting mechanism is fixed to the lower frame 45. A conveyor frame 2 is fixedly installed at the front end of the upper frame 1 through support columns 46. The conveyor frame 2 is composed of two parallel guide rails 47 and portal brackets I3 and II4 respectively provided at the front and rear ends of the guide rails 47. The guide rails 47 are connected and fixed to the upper frame 1. A sensor II is fixed on one end face of the rear end of one side of the guide rail 47. A connecting plate is fixed at the upper end of the portal brackets I3 and II4, and a power screw 5 is provided between the connecting plates.

A bracket 7 is slidably connected, with both ends of the bracket 7 fixedly connected to one end of the guide light bar 8, and the other end of the guide light bar 8 fixedly connected to the seedling support mechanism near the collection tray mechanism. The seedling support mechanism consists of a seedling support active hand 39, a seedling support passive hand 40, an active shaft 41, a passive shaft 42, a seedling support machine cover 43, and a motor II 44. The seedling support machine cover 43 is fixed to the other end of the guide light bar 8. The active shaft 41 and the passive shaft 42 are placed inside the seedling support machine cover 43, and their two ends are rotatably connected to the left and right sides of the seedling support machine cover 43, respectively. Gears are installed at both ends of the active shaft 41 and the passive shaft 42 and mesh with each other. A motor II 44 is fixed to one end of the seedling support machine cover 43. The gear on the output shaft of the motor II 44 is connected to the gear fixed at the center position of the active shaft 41 through a chain 48. The seedling support active hand 39 is fixed to the lower end of the active shaft 41, and the seedling support passive hand 40 is fixed to the lower end of the passive shaft 42.

[0018] A conveying mechanism is fixed to the lower front end of the conveyor frame 2 by angle iron 38. The conveying mechanism consists of a drive shaft 32, one or more driven shafts 33, sprockets 34, chain I 35, conveyor frame 36, conveyor plate 37 and servo motor 9. The servo motor 9 is fixed to the front end of one side guide rail 47. The left and right sides of the conveyor frame 36 are fixed to the guide rail 47 by angle iron 38. The two ends of the drive shaft 32 and the driven shaft 33 are rotatably connected to the two sides of the conveyor frame 36 and are fixed with sprockets 34. The sprockets 34 on both sides are respectively connected to the chain I 35 for transmission. Multiple conveyor plates 37 are evenly arranged at the upper end between the two chains I 35. The output end of the servo motor 9 is fixedly connected to one end of the drive shaft 32.

[0019] A PLC controller is fixed on the frame 10. The PLC controller is electrically connected to motor I 6, servo motor 9, disk motor 14, separate motor 29, motor II 44, motor III 49, sensor I and sensor II respectively.

[0020] In this device, the rice seedling tray is placed on the conveying mechanism, and the groove at the bottom of the tray is engaged with the conveying plate. The servo motor 9 is started, driving the drive shaft 32 to rotate, which in turn moves the conveying mechanism, transporting the seedling tray to the separation position. When sensor II detects that the seedling tray has reached the designated position, it sends a signal to the PLC controller. The PLC controller then starts motors II 44 and III 49, causing the seedling support mechanism to open its support arm to support and fix the seedlings at the front of the tray. Simultaneously, the separation manipulator 31, driven by motor III 49, opens and closes, clamping the front of the plastic seedling tray under the action of the separation manipulator 31 and the U-shaped connecting plate 25. At this point, motors II 44 and III 49 stop working, and motor I 6 and the separation motor 29 start, rotating the power screw 5, causing the seedling support mechanism to move the seedling tray towards the collection mechanism. Simultaneously, the separating motor 29, the U-shaped connecting plate 25, and the separating manipulator 31 move downwards together, separating the plastic seedling tray from the seedlings. The seedling support mechanism places the seedlings on the seedling rack 17. When sensor I detects that the separating manipulator 31 has descended to the designated position, it transmits a signal to the PLC controller. The PLC controller controls motor III 49 to start, and the separating manipulator 31 flips upwards to open, causing the plastic seedling tray to fall. Then, the PLC controller controls motor I 6 and the separating motor 29 to reverse, so that the separating manipulator 31 and the seedling support mechanism return to the initial position to prepare for the next separation stage. At the same time, the tray collecting motor 14 starts, causing the seedling rack 17 to move from the first layer down to the second layer, waiting for the next separation stage to be completed and continuing to move downwards, and so on, until the seedling rack 17 is full of seedlings.
