[0001] This invention relates to the field of potato harvesting technology, and in particular to a human-machine collaborative potato combine harvester with integrated residual film recycling. Background Technology

[0002] Existing small-scale machinery has limited functionality, low intelligence, unstable operation, and requires multiple machines to work together. Potato harvesting mainly employs a segmented method. First, potato diggers are used to dig up the potatoes and spread them flat on the ground. Then, manual labor or specialized machinery is used to pick them up. Manual picking is labor-intensive and inefficient, while mechanical picking may cause further damage, increasing the complexity of the harvest. In addition, during the potato harvesting process, residual film is usually collected after harvesting, increasing the difficulty of the operation, and the time interval may cause the residual film to be blown away by the wind.

[0003] Therefore, there is an urgent need for a human-machine collaborative potato combine harvester that integrates residual film recycling. Summary of the Invention

[0049] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0050] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0051] Reference Figures 1-5 This invention provides a human-machine collaborative potato combine harvester with integrated residual film recycling, comprising:

[0052] Rack 13;

[0053] The excavating shovel is rotatably mounted on one end of the frame 13 via the first electric actuator 15 and the blade plate 14;

[0054] The conveying and lifting device is inclinedly mounted on the frame 13, with the lower end of the conveying and lifting device close to the excavating shovel;

[0055] The film-winding mechanism, located at the high end of the conveying and lifting device, is used to collect residual film on potatoes.

[0056] The film guiding mechanism is installed on the conveying and lifting device. The film guiding mechanism is located between the digging shovel and the film winding mechanism. The film guiding mechanism is used to guide the residual film on the potato to the film winding mechanism.

[0057] The conveying and separating device 9 is mounted on the frame 13, with one end of the conveying and separating device 9 close to the high end of the conveying and lifting device;

[0058] A pair of manual sorting platforms 12 are set on the frame 13, and the pair of manual sorting platforms 12 are located on both sides of the conveying and separating device 9.

[0059] By connecting the frame 13 to the traction device, the traction device drives the frame 13 to move, and the digging shovel digs the potatoes. Then, the conveying and lifting device transfers the potatoes toward the conveying and separating device 9. During this transfer, the film guiding mechanism guides the residual film on the potatoes to the film rolling mechanism, which collects the residual film. When the potatoes are transferred to the conveying and separating device 9, the manual sorting platform 12 enables human-machine cooperation in sorting and diverting the potatoes. This achieves residual film recycling during the harvesting process, eliminating the need for separate recycling of residual film after potato harvesting, reducing the cost of potato harvesting, shortening the potato harvesting time, and improving efficiency.

[0060] Furthermore, the conveying and lifting device is tilted at a large angle, preferably 60°-65°, which shortens the length, forms a large-angle short-distance conveying, reduces the overall length of the machine, and improves the flexibility of the machine during operation and its adaptability to complex terrain.

[0061] In one embodiment of the present invention, the conveying and lifting device includes:

[0062] The first mounting bracket is mounted on the rack 13;

[0063] The first conveying body is mounted on the first mounting frame, and the first conveying body is provided with several comb teeth 4.

[0064] By setting comb teeth 4 on the first conveying body, and the comb teeth 4 having an L-shaped structure, the potato conveying effect can be effectively provided.

[0065] In one embodiment of the present invention, the conveying and separating device 9 includes:

[0066] The second mounting frame is mounted on the frame 13 via the base 11, and a diversion mechanism is provided at the end of the second mounting frame away from the conveying and lifting device.

[0067] The second conveying body is mounted on the second mounting frame;

[0068] A pair of deflectors are mounted on the second mounting bracket.

[0069] In one embodiment of the present invention, the film winding mechanism includes:

[0070] The film winding roller 8 is rotatably mounted on the first mounting frame;

[0071] An electromagnetic clutch 7 is mounted on the first mounting bracket and is connected to the film winding roller 8.

[0072] Multiple film-guiding rods 5 are arranged side by side and rotatably on the first mounting frame, and multiple film-guiding rods 5 are provided with multiple film-pressing rollers 6;

[0073] The blown film device 32 is mounted on the first mounting frame and is located on the side of the plurality of film guide rods 5 away from the film winding roller 8.

[0074] The residual film conveyed is recovered by the cooperation of the film guide rod 5, the pressure roller 6, the film winding roller 8, and the blown film device 32. An electromagnetic clutch 7 is set on one side of the film winding roller 8, and the switch is set on one side of the manual sorting platform 12 so that the personnel behind can disconnect the electromagnetic clutch 7 in time, thereby cutting off the power of the film winding roller 8 and providing safety for the operators.

[0075] In one embodiment of the present invention, the guiding membrane mechanism includes:

[0076] Multiple guide brushes 3 are arranged side by side and rotatably on the first mounting frame. The guide brushes 3 are located above the first conveying body, and the rotation direction of the guide brushes 3 is opposite to the conveying direction of the first conveying body.

[0077] By setting a guide brush 3 to assist in the upward transport of potatoes, the residual film is also transported upward along the conveying and lifting device.

[0078] The guide brush 3 transports the residual film to the film guide rod 5. The film guide rod 5 and the pressure roller 6 work together to separate the residual film from the comb 4 and the first conveying body, and lift it upward and forward. At the same time, the blown film device 32 on one side of the film guide rod 5 generates airflow, which also provides an upward lifting force to the residual film. When the residual film reaches the tail of the film guide rod 5, it will be wound up by the nail teeth 27 on the film winding roller 8, thus completing the recycling of the residual film.

[0079] In one embodiment of the present invention, the diversion mechanism includes:

[0080] Potato outlet 22 is located on the second mounting frame;

[0081] Diverter plate 23 is rotatably mounted at potato outlet 22 via second electric push rod 24;

[0082] A pair of debris channels 21 are provided on both sides of the diversion plate 23;

[0083] A pair of unloading platforms 10 are respectively set below the potato outlet 22 via a third electric push rod 18.

[0084] Potatoes enter the unloading frames of the left and right unloading platforms 10 through the diversion plate 23 at the potato outlet 22. The unloading platform 10 is equipped with a pressure sensing module. When the pressure reaches the preset value, the unloading will be automatic. At the same time, the diversion plate 23 is pushed to the left and right by the second electric push rod 24. The remaining soil and straw fall into the field behind the harvester through the debris channel 21. This improves the convenience of potato unloading and subsequent loading, reduces the labor intensity of manual unloading, and also ensures the continuity of operation and improves work efficiency.

[0085] In one embodiment of the present invention, the film winding roller 8 includes:

[0086] A pair of tapered rollers 26 are symmetrically arranged. The small diameter ends of the pair of tapered rollers 26 are respectively inserted through an inner hexagonal shaft 29 and an outer hexagonal sleeve 28. One of the tapered rollers 26 has an outer hexagonal shaft 25 at its large diameter end, which is used to connect with the output shaft of the electromagnetic clutch 7. The other tapered roller 26 has an optical shaft 30 at its large diameter end, which is rotatably engaged with the first mounting frame through a three-point openable and detachable device 20.

[0087] Multiple spikes 27 are detachably mounted on a pair of tapered rollers 26 via a quick-release device 31.

[0088] The film-rolling roller 8 consists of two symmetrical tapered rollers 26 and a quick-detachable spike 27. The left and right tapered rollers 26 can be connected together by the middle inner hexagonal shaft 29 and the outer hexagonal sleeve 28. The entire film-rolling roller 8 can also be removed as a whole for film unloading on the ground. The end of the left tapered roller 26 is connected to the electromagnetic clutch 7 through the outer hexagonal shaft 25. The right tapered roller 26 is connected to the three-point openable and detachable device on the first mounting frame through the optical shaft 30 on the right side for rotational cooperation, achieving a quick disassembly effect. Multiple of this device can be prepared during harvesting to ensure the continuity of operation, reduce the difficulty of film unloading, and greatly improve the efficiency of operation.

[0089] In one embodiment of the present invention, a vibration device 19 is provided on the conveying and lifting device.

[0090] Vibration device 19 is a high-frequency, low-amplitude cam-based vibration device. Based on chaotic vibration theory, its design is optimized through precise theoretical analysis. A cam with a specific geometric shape is designed to achieve the required vibration characteristics, enhance the nonlinear characteristics of the vibration device, and effectively improve the separation degree of the potato-soil mixture.

[0091] In one embodiment of the present invention, a fixed beam 16 is provided on the frame 13, and a pair of cutting discs 2 are provided on the fixed beam 16, with the pair of cutting discs 2 located at both ends of the digging shovel.

[0092] In one embodiment of the present invention, a contour crushing roller 1 is also provided on the fixed beam 16, and the contour crushing roller 1 is located on the side of the excavator shovel away from the conveying and lifting device.

[0093] Furthermore, angle sensors are installed at the digging shovel and the traction structure of the frame 13. The angle sensors measure the tilt angle of the traction structure and the digging shovel to comprehensively determine the soil penetration depth of the digging shovel. The data is fed back to the detection system in real time, and the soil penetration depth is dynamically adjusted by the hydraulic rod. This improves the quality of potatoes during potato harvesting, greatly reduces the resistance during movement, and improves the harvesting efficiency.

[0094] Furthermore, depth cameras are installed at different points inside the conveyor lifting device. By using the cameras to detect the degree of potato and miscellaneous separation in different parts of the conveyor belt, the vibration device 19 can adjust the rotation speed based on the detected data to achieve the best potato and miscellaneous analysis effect, improve the degree of potato and miscellaneous separation, reduce the intensity of manual labor, and provide convenience for subsequent work after potato harvesting.

[0095] Furthermore, it also includes an online monitoring system, which is mainly used to monitor the relevant parameters of key parts of the machinery in the field in real time. The online monitoring system includes speed sensors installed on each connecting shaft of the harvester, temperature sensors on each bearing seat, depth cameras on the conveying and lifting device, angle sensors on the digging shovel, etc. The tractor driver can monitor the parameter information and warning information of the working machinery in real time through the human-machine interface, so that the driver can make timely adjustments, reduce the driving burden, reduce the probability of the harvester malfunctioning during operation, improve work efficiency, and shorten the harvesting cycle.

[0096] Furthermore, the first mounting frame and the second mounting frame are connected by a connector 17 to improve the stability between the conveying lifting device and the conveying separation device.

[0097] In the description of this invention, it should be understood that the terms "longitudinal", "lateral", "up", "down", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this invention, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this invention.
