[0029] As can be understood, the present invention provides a front frame 10, wherein the front frame 10 includes a first connecting portion 11, a second connecting portion 12 hinged thereto, and a telescopic assembly hinged to the first connecting portion 11 and the second connecting portion 12 at both ends. When dealing with soils of different heights and cabbages at different horizontal positions, the telescopic assembly can be activated to rotate the first connecting portion 11 downward around the second connecting portion 12 to lower the height of the shovel teeth 34 and the cutting blade 31, and then the cutting blade 31 is driven to reciprocate by the first driving structure. When the cabbage is shoveled out of the soil, the roots of the cabbage can be cut synchronously, saving the time for cutting the roots of the cabbage in the subsequent processing process; by arranging a clamping crawler 41 on the second connecting portion 12, when the cabbage is dug out of the soil, it will enter between the two clamping crawlers 41, and by activating the second driving structure, the cabbage can be cut synchronously. The dynamic structure drives the second clamping crawler 41 to operate. The two second clamping crawler belts 41 squeeze the cabbage and lift it to the transportation mechanism 50 at the middle frame 20, and then enter the storage box 59. The cabbage is lifted and transported by clamping. Compared with traditional conveyor belt transportation, it can prevent the cabbage from rolling. At the same time, since the clamping crawler 41 is soft in texture, the cabbage will not be damaged by squeezing. By setting up the AGV trolley 70, the AGV trolley 70 moves synchronously next to the device. When the storage box 59 is full of cabbage, the storage box 59 is transported to the AGV trolley 70 through the transportation mechanism 50. The AGV trolley 70 sends the storage box 59 full of cabbage to the designated location, and finally replaces the new storage box 59 on the transportation mechanism 50. This design structure can ensure the synchronous unloading, avoiding the need for manual unloading in the middle of the machine after it is full of cabbage, resulting in reduced picking efficiency.

[0030] Specifically, in this embodiment, the telescopic assembly includes a first cylinder 13, the first driving structure includes a first motor 32 provided on the first connecting portion 11, and an eccentric rod 33 connected to the first motor 32, and the eccentric rod 33 is connected to the cutting blade 31.

[0031] It can be understood that when the position of the harvesting assembly 30 needs to be adjusted, the first cylinder 13 is started, so that the first cylinder 13 drives the harvesting assembly 30 to rotate downward, thereby adjusting the position of the harvesting assembly 30, and then the cabbage is shoveled out of the soil by the shovel teeth 34, and the eccentric rod 33 is driven to rotate by the first motor 32, thereby driving the cutting blade 31 to rotate back and forth to cut off the roots of the cabbage, thereby saving the time of cutting off the roots of the cabbage later.

[0032] Furthermore, the second driving structure includes a second motor 42 provided on the first connecting portion 11, a first rotating shaft 43 fixedly connected to the second motor 42, and a first transmission wheel 44 fixedly connected to the first rotating shaft 43, and the first transmission wheel 44 is transmission-connected to the clamping crawler 41.

[0033] It can be understood that when the cabbage is harvested from the soil and enters between the measuring and clamping tracks 41, the second motor 42 drives the first rotating shaft 43 together with the first transmission wheel 44 to rotate, and the rotation of the first transmission wheel 44 drives the clamping tracks 41 to operate. The two clamping tracks 41 work together to continuously squeeze and lift the cabbage into the transport mechanism 50.

[0034] Furthermore, the transport mechanism 50 includes a first conveyor belt 51 located at the terminal end of the clamping crawler 41, a third motor 54 provided on the middle frame 20, a second rotating shaft 52 fixedly connected to the third motor 54, and a second transmission wheel 53 fixedly connected to the second rotating shaft 52, and the second transmission wheel 53 is transmission-connected to the first conveyor belt 51; the transport mechanism 50 also includes a second conveyor belt 58 located at the terminal end of the first conveyor belt 51, a fourth motor 55 provided on the middle frame 20, a third rotating shaft 56 fixedly connected to the fourth motor 55, and a third transmission wheel 57 fixedly connected to the third rotating shaft 56, and the third transmission wheel 57 is transmission-connected to the second conveyor belt 58, and the storage box 59 is located on the second conveyor belt 58; a camera is provided above the second conveyor belt 58, and the camera is electrically connected to the fourth motor 55 and the AGV cart 70.

[0035] It can be understood that when the clamping crawler 41 lifts the cabbage onto the first conveyor belt 51, the third motor 54 rotates to drive the second rotating shaft 52 together with the second transmission wheel 53 to rotate, and the second transmission wheel 53 rotates to make the first conveyor belt 51 operate to transport the cabbage on the first conveyor belt 51 to the second conveyor belt 58. In this embodiment, there are four clamping crawlers 41, forming two groups of channels for lifting cabbage. The cabbages in the two groups of channels are all transported to the first conveyor belt 51, so the width of the first conveyor belt 51 is wider; the first conveyor belt 51 lifts the cabbage After the vegetables are transported to the second conveyor belt 58, they enter the storage box 59. When the camera recognizes that the storage box 59 is full of cabbage, it sends a signal to start the fourth motor 55 and the AGV cart 70. The fourth motor 55 rotates to drive the third rotating shaft 56 connected to the third transmission wheel 57 to rotate. The rotation of the third transmission wheel 57 causes the second conveyor belt 58 to operate, so as to transport the storage box 59 on the second conveyor belt 58 to the AGV cart 70. The AGV cart 70 then transports the cabbage in the storage box 59 to the designated location, thereby realizing the unloading operation during the receiving process.

[0036] Furthermore, the cabbage harvester also includes a transplanting mechanism 60, which includes a slide frame 61 located above the middle frame 20, a magnetic component 64 sliding along the slide frame 61, and a second cylinder 62 connecting the slide frame 61 and the middle frame 20, the magnetic component 64 is provided with an electromagnet 65, and a spare storage box 63 is provided below the magnetic component 64; the magnetic component 64 is provided with a slide rail cylinder, and the slide frame 61 is provided with a slide block 67 for the slide rail cylinder to slide.

[0037] It can be understood that by arranging a spare storage box 63 below the magnetic part 64, when the storage box 59 located on the second conveyor belt 58 is transported to the AGV cart 70, the electromagnet 65 of the magnetic part 64 is energized, and then the entire slide 61 is lowered by the second cylinder 62 to drive the magnetic part 64 to descend. After the electromagnet 65 adsorbs the spare storage box 63, the second cylinder 62 raises the entire slide 61 to drive the magnetic part 64 to rise, and then drives the magnetic part 64 to move along the slide 61 to the top of the second conveyor belt 58 through the slide rail cylinder, and then lowers the magnetic part 64 again through the second cylinder 62, and then de-energizes the electromagnet 65, and moves the spare storage box 63 down to the second conveyor belt 58, and then conveys the spare storage box 63 to the terminal of the first conveyor belt 51 through the second conveyor belt 58 to serve as a new storage box 59.

[0038] In summary, the cabbage harvesting machine in the above embodiment of the utility model can cope with soil of different heights and cabbages at different horizontal positions, while saving the time for cutting the roots of cabbage in the subsequent processing process. By setting up an AGV cart, the unloading can be carried out synchronously.
