DETAILED DESCRIPTION

[0025] The following will be described in detail in combination with the accompanying Figures 1-5 The application will be further described in detail.

[0026] The application embodiment discloses a seedling tray automatic tray feeding machine.

[0027] Referring to Figure 1The tray automatic feeding machine comprises an entering tray mechanism 1, an exiting tray mechanism 2, a supporting frame 3, a lifting mechanism 4 for lifting the seedling tray and a carrying manipulator for grabbing the seedling tray. The entering tray mechanism 1 is arranged on the entering tray station of the frame 3 near the bottom position and is used for conveying the seedling tray to the entering tray station. The lifting mechanism 4 is arranged on the frame 3 and is used for lifting and conveying the seedling tray on the entering tray station to a predetermined position. Meanwhile, the carrying manipulator is arranged on the top of the frame 3 to grab the seedling tray moved to the predetermined position by the lifting mechanism 4 and carry the seedling tray to the exiting tray station on the side of the frame 3, and then the exiting tray mechanism 2 is used for spacingly conveying the seedling tray.

[0028] Since the seedling tray is placed on the exiting tray station by the carrying manipulator, and the carrying manipulator has fixed steps and a predetermined action period controlled by the system, the seedling tray can be regularly and spacingly placed on the exiting tray station by the system adjustment, so that the seedling tray can be smoothly used by the seedling tray assembly line, and the overall process is improved.

[0029] Meanwhile, the seedling tray is limited during the operation of the feeding machine, so that the seedling tray cannot collide with the feeding machine and other seedling trays, thereby preventing the seedling tray from being damaged.

[0030] With reference to Figure 1 and Figure 2 , the frame 3 is provided with an entering tray opening on the left side, and vertical guide plates 6 are fixedly installed on both sides of the entering tray opening. The frame 3 is provided with an entering tray positioning plate 8 on the right side for moving the seedling tray to the lifting station, and the entering tray station is arranged between the entering tray opening and the entering tray positioning plate 8, and the exiting tray station is located outside the entering tray positioning plate 8 to avoid collision between the seedling trays and damage to the seedling trays.

[0031] With reference to Figure 1 and Figure 2 , further, the frame 3 is provided with an electrical control box at the bottom, and the electrical control box is located directly below the entering tray station to adjust the running speed of each actuator and ensure the smooth operation of the whole device.

[0032] In the present application, the entering tray mechanism 1 is composed of a first conveying belt 11, a first belt pulley 12 and a first driving motor 13, and the exiting tray mechanism 2 is composed of a second conveying belt 21, a second belt pulley 22 and a second driving motor 23.

[0033] With reference to Figure 1 and Figure 3, specifically, the carrying manipulator includes a swing arm mechanism 5 for moving the seedling tray and a clamping structure for clamping the seedling tray. The swing arm mechanism 5 specifically includes a rotary actuator 51 and a swing arm support 52. The rotary actuator 51 is fixedly installed on the rack 3, and a rotary shaft 53 is rotatably arranged on the rotary actuator 51. The rotary shaft 53 is fixedly connected with the action execution end of the swing arm support 52. The other end of the swing arm support 52 is rotatably installed with a horizontal adjusting shaft 54 for adjusting the position of the seedling tray in the horizontal direction. The swing arm support 52 is rotatably connected to the middle part of the horizontal adjusting shaft 54 in the length direction, and the two ends of the horizontal adjusting shaft 54 are respectively connected with the clamping structure for clamping the seedling tray and the horizontal adjusting mechanism for moving the position of the seedling tray in the horizontal direction. The swing arm support 52 and the horizontal adjusting mechanism jointly act to drive the seedling tray clamped by the clamping structure to move smoothly to the predetermined position on the tray ejection mechanism 2.

[0034] With reference to Figure 3 Further, the horizontal adjusting mechanism specifically includes a fixed wheel 55 fixedly installed on the rack 3 and a movable wheel 56 installed on the horizontal adjusting shaft 54. The fixed wheel 55 and the movable wheel 56 are connected through a synchronous belt transmission mechanism 57 or a chain transmission mechanism. The connection mechanism between the fixed wheel 55 and the movable wheel 56 of the present application can meet the requirement of synchronous rotation of the fixed wheel 55 and the movable wheel 56. The above two transmission mechanisms are only the preferred solution of the present embodiment, and do not limit the present application.

[0035] With reference to Figure 3 Further, the clamping structure specifically includes a support frame 71, a clamping jaw 72 and a driving member 73. The geometric center of the support frame 71 is provided with a fixed part 711, and the clamping jaw 72 has two ends symmetrically hinged to the support frame 71, for respectively clamping the opposite two ends of the seedling tray. The driving member 73 is arranged between the clamping jaw 72 and the support frame 71, for driving the clamping jaw 72 to rotate, realizing the opening or clamping of the clamping jaw 72.

[0036] Because the function of the driving member 73 at this position is to drive the clamping jaw 72 to rotate, any electrical equipment that can realize this function, such as motor, air cylinder, etc., should be included in the protection scope of the present application. Similarly, any structure obtained by simple change of the structure here should be within the protection scope of the present application.

[0037] With reference to Figure 3 and Figure 4The fixed part 711 comprises a connecting plate integrally connected to the middle part of the support frame 71, and the geometric center of the connecting plate is provided with a main side hole 7111 and a plurality of sub-side holes 7112 which are distributed at equal intervals along the circumference of the main side hole 7111. The horizontal adjusting shaft 54 is rotationally connected to the support frame 71 through the main side hole 7111, so as to move the position of the whole clamping structure and the seedling tray connected to the clamping structure. A flange 541 is rotationally arranged on the horizontal adjusting shaft 54, and a plurality of bolts which are respectively correspondingly threaded with the plurality of sub-side holes 7112 are threaded on the flange 541, so as to ensure that the horizontal adjusting shaft 54 is always stably connected to the support frame 71.

[0038] With reference to Figure 2 And Figure 5 The lifting mechanism 4 preferably adopts a chain type lifting mechanism 4, which specifically comprises lifting wheels 41, a lifting chain, lifting plates 43 and a lifting motor 44. The front and rear sides of the rack 3 are both provided with transmission shafts 45 arranged in an up-down manner, the lifting wheels 41 are fixedly installed on the transmission shafts 45, the lifting chain is commonly wound on the two lifting wheels 41 located in the same vertical plane, and the lifting chain is driven to run through the transmission connection of the lifting motor 44 and the lifting wheels 41. The lifting plates 43 for placing the seedling trays are fixedly installed on the lifting chain and move up and down with the lifting chain.

[0039] Further, a speed reduction transmission mechanism is arranged between the transmission shaft 45 and the lifting motor 44, which comprises a linkage shaft 461 and two transmission execution mechanisms 46. The output ends of the two transmission execution mechanisms 46 are fixedly connected with the front and rear transmission shafts 45 respectively, and the linkage shaft 461 is arranged between the output ends of the two transmission execution mechanisms 46. The input end of one of the transmission execution mechanisms 46 is connected with the lifting motor 44 through a belt transmission mechanism, so as to flexibly control the rotating speed of the lifting transmission shaft 45.

[0040] It should be noted that the transmission execution mechanism 46 in the present application is used to synchronize the rotating speed of the two transmission shafts 45 located in the same horizontal plane in the lifting mechanism 4, so as to ensure that the seedling tray always remains horizontal during lifting. Therefore, the transmission execution mechanism can be a worm gear reducer, a bevel gear connecting structure or a synchronous transmission belt.

[0041] The implementation principle of the seedling tray automatic feeding machine according to the embodiment of the present application is as follows:

[0042] The seedling tray is conveyed by the first conveying belt 11 of the feeding mechanism 1, enters the inside of the rack 3 through the feeding port, and abuts against the feeding positioning plate 8. At this time, the seedling tray is placed on the lifting plate 43 of the lifting mechanism 4 and is conveyed to the clamping station of the clamping structure by the lifting chain.

[0043] After the two clamping jaws 72 on the clamping structure clamp the two ends of the seedling tray by rotating and vertically moving, the clamping jaws 72 and the seedling tray are moved to the tray discharging mechanism 2 by the horizontal adjusting shaft 54, and the tray feeding process of the seedling tray is completed.

[0044] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application, so: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
