[0002] The statements herein provide only background information related to this invention and do not necessarily constitute prior art.

[0003] Potatoes, also known as Irish potatoes, grow underground. Harvesting potatoes requires cutting the vines beforehand and then digging them out of the soil for transport. While some large-scale harvesting machines are available, for small-scale individual potato growers, existing potato harvesters sometimes remove the plastic film covering the surface ridges before harvesting, while others leave it untouched. Larger-scale growers generally don't remove the film beforehand because it's too labor-intensive, and traditional potato harvesters often lack the function to handle the plastic film, simply breaking it up in the field and causing soil pollution.

[0019] like Figures 1-11 As shown in the embodiment of this utility model, a potato combine harvester is described, including a harvester body. The harvester body is provided with a power mechanism 2, a soil loosening and film removal mechanism 1, a stem and leaf removal mechanism 3, a vibration digging mechanism 4, a soil breaking mechanism 5, a conveying mechanism 6, and a collection mechanism 7. The soil breaking mechanism 5 is located at the rear of the vibration digging mechanism 4, and the collection mechanism 7 is located at the top of the harvester body. The conveying mechanism 6 is arranged in a U-shape and connects to the rear of the vibration digging mechanism 4 and the input end of the collection mechanism 7.

[0020] like Figure 2As shown, the front of the power mechanism 2 is connected to the soil loosening and film removal mechanism 1, the lower part is connected to the stem and leaf removal mechanism 3, and the rear is connected to the vibratory digging mechanism 4. The soil loosening and film removal mechanism 1 includes a vibratory soil loosening component and a film roll 108. The soil loosening component includes a vibratory digging shovel motor 107, a limiting sleeve 103, a deep soil digging shovel 102, and a vibratory digging shovel 101. Cranks 104 are provided on both sides of the deep soil digging shovel 102. The vibratory digging shovel motor 107 is connected to the cranks 104 through a gear set 106, and the cranks 104 are connected to the vibratory digging shovel 101 through the limiting sleeve 103. The film roll 108 is composed of six barbed plates and is connected to the film roll motor 105 through a linkage mechanism to perform rotary motion.

[0021] Specifically, the power mechanism 2 drives the vibratory excavator motor 107, which in turn drives the gear set 106 to transmit power, causing the crank 104 to rotate eccentrically. The crank 104 converts the circular motion into a reciprocating vibration with a limited stroke through the limiting sleeve 103, driving the deep soil excavator 102 to perform periodic soil loosening operations. The synchronously started plastic film reel motor 105 drives the barbed plate to perform circular motion through the linkage mechanism. During the rotation, the barbed plate pierces the edge of the loosened soil ridge plastic film. As the machine moves forward, the pierced plastic film is gradually peeled off from the soil and wound up for recycling under the continuous rotation of the reel. This process completes the plastic film peeling during the soil loosening stage, avoiding secondary damage to the plastic film in subsequent operations.

[0022] like Figure 3 , Figure 4 and Figure 5 The stem and leaf removal mechanism 3 shown is connected to the bottom of the power mechanism 2 via a hinge. It includes a hydraulic cylinder 302, a stem and leaf cutting motor 306, a collection box 301, a worm gear 304, a worm 305, and a rack and pinion stem cutter 303. Hydraulic cylinders 302 are provided on both sides of the collection box 301. A drive gear 307 that cooperates with the rack and pinion stem cutter 303 is provided inside the collection box 301. The stem and leaf cutting motor 306 is connected to the worm gear 304 through the worm 305. The worm gear 304 and the drive gear 307 in the collection box are coaxially arranged to drive the rack and pinion stem cutter 303 to move.

[0023] Specifically, the stem and leaf removal mechanism 3 is connected to the power mechanism 2 via a hinge, forming an adjustable-angle connection. Hydraulic cylinders 302 are symmetrically arranged on both sides of the collection box 301, controlling its lifting and lowering posture via hydraulic power. The stem and leaf cutting motor 306 drives the worm gear 305 to reduce the rotation of the worm wheel 304. The coaxial drive gear 307 of the worm wheel 304 meshes with the rack and pinion stem cutter 303, converting the rotational motion into a linear reciprocating cutting motion of the rack and pinion stem cutter 303. During the cutting process, the collection box 301 adjusts its position synchronously with the hydraulic cylinder 302, allowing the cut stems and leaves to fall directly into the box. The self-locking characteristic of the worm wheel 304 and worm gear 305 transmission system prevents external interference from causing the rack and pinion stem cutter 303 to move in the opposite direction, ensuring a stable cutting process.

[0024] Specifically, such as Figure 5 As shown, the drive gear 307 is divided into upper and lower parts. The lower part has full teeth that mesh with each other, while the upper part has fewer teeth that mesh with the rack stem cutter 303. During operation, the rack stem cutter 303 first meshes with one of the gears, while the other is in the position with fewer teeth. When it moves to the limit position, the first meshing gear is in the position with fewer teeth, and the second gear meshes with the rack stem cutter 303. Then it moves back to the limit position. In this way, the rack stem cutter 303 makes reciprocating motion, which works with the teeth of the collection box 301 to perform stem cutting.

[0025] like Figure 6 , Figure 7 , Figure 8 and Figure 9 As shown, the vibratory excavator 4 includes a front wheel 401, a rear wheel 404, a vibratory excavator motor 403, and an excavator shovel assembly. The front wheel 401 is connected to the vibratory excavator motor 403 via a front wheel belt 402, and the rear wheel 404 is connected to the frame via a rear wheel hydraulic cylinder 405. The excavator shovel assembly includes a movable potato excavator shovel 411 and a fixed potato excavator shovel 414. The fixed potato excavator shovel 414 has excavator shovel cranks 412 on both sides, which are connected to the rotating connecting rod 413 on the movable potato excavator shovel 411 via a connecting rod.

[0026] Specifically, the vibratory excavator motor 403 drives the front wheel 401 to rotate via the front wheel belt 402, providing basic traction power for the mechanism; the rear wheel hydraulic cylinder 405 adjusts the frame height according to soil conditions to control the digging depth. The cranks on both sides of the fixed potato digging shovel 414 rotate with the front wheel 401, driving the rotating connecting rod 413 of the movable potato digging shovel 411 through the connecting rod, causing the movable shovel to reciprocate under the guidance of the fixed shovel. After the fixed shovel cuts into the soil, the swinging motion of the movable shovel further breaks up the soil adhering to the potato surface, while avoiding damage to the potato skin caused by hard pulling. A conveyor chain is also set behind the digging shovel assembly to continuously transport the separated potatoes to subsequent processes, preventing accumulation and blockage.

[0027] The vibratory excavator 4 also includes a front roller 408 and a rear roller 406. The two sides of the front roller 408 are connected to the turntable gear 410 through the roller belt 409. The turntable gear 410 is connected to the vibratory excavator motor 403 through the motor drive belt. The rear roller 406 is connected to the turntable gear 410 through the swing linkage 407.

[0028] Specifically, the vibratory excavator motor 403 drives the turntable gear 410 to rotate via a motor drive belt. The turntable gear 410 drives the front roller 408 to rotate synchronously via the roller belt 409, causing the raised structure on the surface of the front roller 408 to roll and peel off the soil surface, separating the mulch film from the soil. During rotation, the turntable gear 410 pushes the rear roller 406 to oscillate back and forth via the swing linkage 407. The spiked structure on the surface of the rear roller 406 picks up and collects residual mulch film fragments from the soil during the oscillation. The linkage mechanism between the front roller 408 and the rear roller 406 makes the mulch film peeling and fragment collection a continuous operation process, avoiding the defect of traditional machinery where a single roller can only complete the initial peeling.

[0029] like Figure 10 As shown, the soil crushing mechanism 5 includes a working frame 502, a lead screw 501, a slider, a robot arm 505, and a vision recognition camera 506. The lead screw 501 is connected to the soil crushing motor via a belt. A robot arm slider 503 is installed on the slider. The robot arm slider 503 is connected to the robot arm 505 via a robot arm hydraulic cylinder 504. The vision recognition camera is fixed on the working frame 502.

[0030] Specifically, the soil-crushing mechanism 5 is installed behind the vibratory excavation mechanism 4. A lead screw 501 drives a robotic arm 505 to crush the excavated soil. A visual recognition camera detects residual plastic film in real time and guides the robotic arm 505 to remove it directionally. The conveying mechanism 6 uses a four-section zigzag conveyor belt to form a U-shaped conveying channel. During transportation, the material undergoes multiple turning vibrations, causing the loose soil to naturally fall off. The collection mechanism 7 is located at the top of the equipment. A double-layer sprocket roller conveyor belt guides potatoes of different sizes to their corresponding collection boxes 301. A rotating paddle 709, driven by a chain shaft 702, periodically moves the material to accelerate sorting.

[0031] A visual recognition camera acquires real-time image data of the soil fragmentation area and uses an edge detection algorithm to locate the coordinates of the plastic film fragments. A soil-crushing motor drives a lead screw 501 to rotate, moving a robotic arm slider 503 along a guide rail to the target area. The robotic arm's hydraulic cylinder 504 controls the gripper to close according to a preset pressure value, grabbing the soil clods containing the plastic film and lifting them to the separation station. During the movement of the robotic arm 505, the vibration amplitude of the gripper is adaptively adjusted through the gap between the slider and the guide rail, preventing the soil clods from breaking due to rigid collisions. The separated plastic film fragments are transferred to a collection device, while the soil falls back to the ground under gravity.

[0032] like Figure 11As shown, the conveying mechanism 6 includes a first conveyor belt 604, a second conveyor belt 605, a third conveyor belt 606, and a fourth conveyor belt 609 arranged in series. The first conveyor belt 604 is connected to a drive belt motor 601 through a drive bevel gear 602 and a driven bevel gear 603. The second conveyor belt 605 is provided with a limit shaft and a support shaft. The third conveyor belt 606 is connected to the drive bevel gear 602 through a roller shaft drive belt. The fourth conveyor belt 609 is connected to an independent motor.

[0033] Specifically, the first conveyor belt 604 converts the power of the drive belt motor 601 into horizontal conveying force through the meshing of the driving bevel gear 602 and the driven bevel gear 603. The second conveyor belt 605 maintains the material conveying trajectory through a rigid frame formed by the limiting shaft and the support shaft. The third conveyor belt 606 maintains synchronous operation with the driving bevel gear 602 via the roller shaft drive belt. The fourth conveyor belt 609 achieves independent speed adjustment at the end through an independent motor. At the junction of the second conveyor belt 605 and the third conveyor belt 606, the rotating brush 607 is driven to rotate at high speed by the brush motor 608. When the flexible bristles come into contact with the potato surface, they generate friction, peeling off the attached plastic film fragments and sweeping them into the collection device. The first three sections of the four-stage conveyor belt use a linkage drive mode to ensure basic conveying efficiency, while the fourth conveyor belt 609 at the end uses independent speed adjustment to match different collection conditions.

[0034] like Figure 12 As shown, the conveying mechanism 6 also includes a rotating brush 607, which is disposed between the second conveyor belt 605 and the third conveyor belt 606 and is driven to rotate by a brush motor 608.

[0035] Specifically, when the second conveyor belt 605 transports the material carrying potatoes and plastic film fragments to the end, the material enters the transition area between the second conveyor belt 605 and the third conveyor belt 606 under the guidance of the limiting shaft. At this time, the rotating brush 607 rotates counterclockwise at a preset speed driven by the brush motor 608, and the bristles come into contact with the falling material. Because the plastic film fragments are thin and have weak adhesion, they detach from the potato surface under the continuous sweeping action of the bristles and are guided to the side collection port by the airflow disturbance generated by the brush rotation. Due to their large weight and smooth surface, the potatoes fall directly into the mesh belt gap of the third conveyor belt 606 under the action of gravity and continue to be transported. The brush motor 608 dynamically adjusts the speed according to the material flow rate. When it detects an increase in the amount of plastic film residue, it increases the speed to enhance the cleaning force, and vice versa to reduce energy consumption.

[0036] like Figure 13 As shown, the collection mechanism 7 includes a small potato double-layer sprocket roller conveyor belt 701, a medium potato double-layer sprocket roller conveyor belt 706, and a large potato double-layer sprocket roller conveyor belt 707, which are respectively connected to the potato collection box 703. Each conveyor belt is connected to the sprocket shaft drive belt 708 through the sprocket shaft gear 705.

[0037] Specifically, the small potato double-layer sprocket roller conveyor belt 701, the medium potato double-layer sprocket roller conveyor belt 706, and the large potato double-layer sprocket roller conveyor belt 707 are designed with different roller spacings according to the size of the potatoes. When potatoes pass through the conveyor belt, potatoes smaller than the roller spacing will naturally fall to the lower conveyor channel, while potatoes larger than the roller spacing will continue to be conveyed forward. The double-layer sprocket structure uses upper and lower sprockets to alternately support the rollers, reducing conveyor belt deformation caused by vibration and ensuring smooth potato transportation. The sprocket shaft gear 705 and the sprocket shaft drive belt 708 are driven by the same power source, keeping the conveyor belts running synchronously and preventing potatoes from accumulating at the conveyor belt joints due to speed differences. The potato collection box 703 connected to the end of the conveyor belt receives potatoes of corresponding sizes through a chute, completing the classified storage. The collecting mechanism 7 is equipped with a rotating paddle 709, which is connected to the chain shaft 702 via a rotating paddle belt 704. A platform plate 710 is provided below the rotating paddle 709, and the platform plate 710 is fixed by a collecting box support profile 711. The bottom of the conveying mechanism 6 is equipped with hydraulic adjustable wheels, and baffles are provided on both sides. A limiting shaft for adjusting the distance between the hydraulic adjustable wheels is provided between the first conveyor belt 604 and the second conveyor belt 605.

[0038] Specifically, the rotating paddle 709 rotates continuously under the drive of the chain shaft 702. When its teeth contact potatoes of different sizes, they perform a sorting action. Smaller potatoes are pushed to the lower conveyor belt, while larger potatoes enter the upper conveyor belt along the tangential direction of the paddle. The platform plate 710 is fixed to the frame of the collecting mechanism 7 by a rigid support profile to prevent mechanical vibration from causing the rotating paddle 709 to deviate. The hydraulically adjustable wheels change the wheel spacing through the extension and retraction of the hydraulic cylinder 302, allowing the machine to maintain stable movement in narrow or wide ridge terrain. Side baffles are arranged along the edge of the conveyor belt to form a semi-enclosed channel to prevent potatoes from rolling sideways. The limiting shaft changes the distance between the first conveyor belt 604 and the second conveyor belt 605 through threaded adjustment. When the hydraulically adjustable wheels adjust the wheel spacing, the limiting shaft changes its length synchronously to maintain the connection accuracy of the conveyor belts.

[0039] The working principle of this utility model is as follows: The power mechanism drives the soil loosening and film removal mechanism. The vibratory excavator motor drives the crank through a gear set, causing the vibratory excavator to vibrate and loosen the soil reciprocally. Simultaneously, the film roll motor starts, and the barbed plate rotates to peel off and roll up the film. In the stem and leaf removal mechanism, the hydraulic cylinder adjusts the height of the collection box, and the stem and leaf cutting motor drives the rack and pinion stem cutter to reciprocate through a worm gear, cutting off the stems and leaves that fall into the collection box. The vibratory excavator motor drives the front wheel and excavator assembly, which cooperates with the fixed and movable excavator to dig potatoes. The front roller rolls to peel off the film, and the rear roller swings to collect residual fragments. The soil crushing mechanism uses a lead screw to drive a robotic arm to crush the soil, and visual recognition guides the removal of residual film. The conveying mechanism transports potatoes via four U-shaped conveyor belts, and rotating brushes remove impurities from the potato surface. The collection mechanism uses conveyor belts with different roller spacings for grading, and rotating paddles assist in sorting. Finally, the potatoes are collected in the corresponding collection boxes, realizing integrated operation of film recycling, stem and leaf treatment, excavation, soil crushing, conveying, and classified collection.

[0040] Although the specific embodiments of the present utility model have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present utility model. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solution of the present utility model are still within the scope of protection of the present utility model.
