[0042] The present invention provides an all-in-one bagging machine for lettuce, which can sequentially realize the functions of defoliating, harvesting, bundling, and storing the lettuce, while also completing soil turning work. It has a high degree of automation and solves the problem that the lettuce harvesting process in traditional operation modes requires a large amount of manpower. In addition, multiple defoliating knives are connected in series by springs, and a flexible defoliating device can self-adjust according to lettuces of different diameters, that is, the flexible defoliating device can self-adjust and quickly peel off the outer leaves of the lettuce without damaging the lettuce.

[0043] In order to facilitate understanding of the present invention during specific use, the present invention will be described with reference to the accompanying drawings.

[0044] The overall working process of the integrated bag collecting machine is as follows: first, the lettuce robot moves forward, and the lettuce enters the flexible leaf removal device 1. The robot stops and completes the leaf removal of the lettuce; then, the robot continues to move forward, and the harvesting knife disc 20101 at the front end of the first-level harvesting and transmission device 2 cuts the root of the lettuce to complete the harvesting of the lettuce. The lettuce enters the first-level transmission device 202 and is transmitted upward at an angle of 60°; the lettuce enters the second-level transmission device 3, and the two side mechanisms of this device are respectively expanded outward by 30° and tilted downward by 30° relative to the first-level transmission device 202, so as to ensure the smooth change of the lettuce posture, and then enter the next device; enter the third-level bundling transmission Device 4, when detecting that a sufficient amount of lettuce is piled on the conveyor belt of the three-level transmission mechanism 401, the conveyor belt of the three-level transmission mechanism 401 starts to work, and the lettuce enters the bundling mechanism 402. The conveyor belt of the three-level transmission mechanism 401 stops working. After the lettuce is bundled, the conveyor belt of the three-level transmission mechanism 401 starts to work again, allowing the lettuce to enter the next device; enters the intelligent storage device 5, and when it detects that the lettuce fills the frame of the intelligent storage device 5, the lettuce robot ends the harvesting work, returns to the designated position, and unloads; when the lettuce is in the lettuce field and is in the forward state, the soil turning device 6 starts to turn the soil synchronously.

[0045] Defoliation process: see Figures 4 and 5. After the lettuce enters the flexible defoliation device 1, the guide frame 101 first gradually applies side constraints, and the package collecting integrated machine continues to move forward. When the constraint lever 103 on the left senses the contact of the lettuce, the constraint servo 102 on the right works, causing the constraint lever 103 on the right to rotate, and the constraint levers 103 on the left and right sides clamp and apply front and rear constraints to the lettuce. Subsequently, the servo track motor 106 works and moves downward along the track 104 to drive the defoliation knife disc 105 to remove the lettuce leaves. After the defoliation is completed, the servo track motor 106 returns to its original position, and the defoliation fan 107 works to blow off the lettuce leaves to prevent the leaves from sticking to the defoliation knife 10506 and the lettuce surface. When it is detected that the servo track motor 106 has returned to its original position, the constraint servos 102 on the left and right sides work, driving the constraint levers 103 on the left and right sides to loosen and rotate to the front and rear positions. After the lettuce enters the next device, the constraint lever 103 on the left returns to the position shown in the figure.

[0046] Among them, in the structure of the leaf removing blade disc 105, the limit element frame 10502 can be slidably adjusted relative to the leaf removing blade frame 10501 to achieve the adjustment of the minimum diameter formed by multiple leaf removing tools 10506. Specifically, the limit frame 10502 extends from the bottom and supports the leaf removing tool 10506, which can prevent the leaf removing tool 10506 from continuing to shrink inward under the action of the spring 10505, thereby completing the minimum diameter constraint. The minimum constraint diameter can be adjusted by adjusting the limit nut 10503 and moving the limit frame 10502; when the leaf removing tool 10506 works on lettuce surfaces with different diameters, the inner rounded corner of the tool body 105061 presses against the lettuce surface to prevent damage to the lettuce, and the leaf removing blade 105062 cuts the lettuce leaves. The spring 10505 is connected in series with the leaf removing tool 10506 for flexible adjustment, thereby achieving the constraint of the minimum diameter of lettuce leaf removal and adapting to the leaf removal working conditions of lettuce surfaces with different diameters.

[0047] Harvesting and transmission process: See Figures 6 and 7. The first-level harvesting and transmission device 2 and the second-level transmission device 3 realize the harvesting and transmission functions of the lettuce. The advantage is that the second-level transmission device 3 realizes the smooth adjustment of the lettuce posture, providing a good foundation for subsequent work.

[0048] Bundling process: see Figures 8 to 10. When it is detected that a sufficient amount of lettuce is accumulated in the three-level transmission mechanism 401, the three-level transmission mechanism 401 works to transport the lettuce to the bundling mechanism 402. At this time, the limiting shaft 40215 on the movable bracket 40211 is located on the side closest to the three-level transmission mechanism 401. The starting end of the tape installed on the rotating frame 40205 is pre-bonded to the limiting shaft 40215, and the tape on the rotating frame 40205 is on the same side of the limiting shaft 40215. Subsequently, the bundling stepper motor 40202 works to drive the rotating frame 40205 to rotate 180° clockwise so that the tape installed on the rotating frame 40205 tightly surrounds the lower half of the lettuce. On the right side of the limiting shaft 40215, a tape cutting mechanism consisting of a dual-axis cylinder 40214 and a cutting blade 40213 is installed. ;The double-axis cylinder 40214 pushes the cutting blade 40213 to accurately cut the tape; the mobile bracket 40211 drives the limit shaft 40215 to move backward, and at the same time, the bundling stepper motor 40202 works to drive the rotating frame 40205 to continue rotating, ensuring that the bundling is firm and the tape returns to the starting position; after the bundling is completed, the limit shaft 40215 moves forward so that the tape is bonded at the limit shaft 40215; finally, the mobile bracket 40211 drives the limit shaft 40215 to move forward, and the limit shaft 40215 returns to the side closest to the three-level transmission mechanism 401, and the double-axis cylinder 40214 pushes the cutting blade 40213 to accurately cut the tape; in this way, the lettuce is neatly bundled, and then the three-level transmission mechanism 401 starts again to smoothly transfer the bundled lettuce to the next device of the robot.

[0049] Collection process: See Figure 11. The bundled lettuces are collected in a frame structure formed by the bottom frame 501, the side panels 502, and the bottom panel 503. When unloading is required, the electric piston rod 507 of the electric piston cylinder 506 moves to lift one side of the bottom panel 503. The bundled lettuces slide out along the raised bottom panel 503 due to their own weight to achieve unloading.

[0050] In addition, the steering of the chassis 7 is achieved through the differential of the power DC motor 708. The bag collecting machine also has a soil turning function, as shown in Figures 12 and 13. The soil turning DC motor 601 is installed on the soil turning motor bracket 602 and realizes power output in sequence through the coupling 603, the transmission shaft 604, and the reduction box 605. Then, the soil turning action of the soil turning shovel 614 is realized by arm 1 611, arm 2 612, and arm 3 613.

[0051] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations are possible. Any modifications, equivalent substitutions, or improvements within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
