[0035] The following will be combined with the accompanying drawings of the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments. Similar component numbers in the drawings represent similar components. Obviously, the embodiments described below are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] It will be understood that when used in this specification and the appended claims, the terms “comprises” and “comprising” indicate the presence of described features, integers, steps, operations, elements and / or components, but do not preclude the presence or addition of one or more other features, integers, steps, operations, elements, components and / or groups thereof.

[0037] It should also be understood that the terms used in this description of the embodiments of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the embodiments of the present invention. As used in the description of the embodiments of the present invention and the appended claims, the singular forms "a", "an", and "the" are intended to include the plural forms unless the context clearly indicates otherwise.

[0038] like Figures 1-15 As shown, the present invention provides a combined intelligent harvester, comprising: an excavator 1, a potato conveyor 61, a slope weeder 62, a ring lifting device 7, a V-belt conveyor 59 and a rejection and screening device 60; the discharge end of the excavator 1 is located on one side of the feed end of the potato conveyor 61; the discharge end of the potato conveyor 61 is located on one side of the feed end of the slope weeder 62; the discharge end of the slope weeder 62 is located on one side of the feed end of the ring lifting device 7; the discharge end of the ring lifting device 7 is located on one side of the feed end of the V-belt conveyor 59; the discharge end of the V-belt conveyor 59 is located on one side of the feed end of the rejection and screening device 60; wherein, the transported objects are transported in sequence via the excavator 1, the potato conveyor 61, the slope weeder 62, the ring lifting device 7, the V-belt conveyor 59 and the rejection and screening device 60.

[0039] Specifically, the excavator 1 is used to dig out potatoes; after the potatoes are dug out by the excavator 1, the impurities are preliminarily screened out by the potato conveyor 61, the slope weeder 62, and the annular lifting device 7, and then the impurities remaining after the preliminarily screening out impurities are screened out again by the V-belt conveyor 59 to further clean the impurities, and finally all impurities except potatoes are accurately removed by the removal and screening device 60, thereby completing the deep removal of impurities; therefore, after the impurities are removed step by step by the potato conveyor 61, the slope weeder 62, the annular lifting device 7, the V-belt conveyor 59 and the removal and screening device 60, the deep removal of impurities can be achieved, so that the harvested potatoes are cleaner and less susceptible to damage by impurities.

[0040] Furthermore, the potato conveyor 61 includes a screen conveyor belt 14, a first chain rod 18 and a first drive unit 17; the screen conveyor belt 14 includes a screen conveyor belt feed end 15 and a screen conveyor belt discharge end 16; the screen conveyor belt feed end 15 is located at one end of the screen conveyor belt 14, and the screen conveyor belt discharge end 16 is located at the other end of the screen conveyor belt 14; the discharge end of the excavator 1 is located on one side of the screen conveyor belt feed end 15; the first drive unit 17 is connected to the screen conveyor belt 14; and a plurality of first chain rods 18 are arranged at intervals on the screen conveyor belt 14.

[0041] Specifically, after the excavator 1 digs out the impurities and potatoes, they are sent to the screen conveyor belt feed end 15 on the screen conveyor belt 14 through the discharge end of the excavator 1, and then the first drive unit 17 drives the screen conveyor belt 14 to transport the potatoes. Since the multiple first chain rods 18 are arranged at intervals on the screen conveyor belt 14, part of the sand and soil falls through the gaps between the multiple first chain rods 18, completing the preliminary screening of impurities.

[0042] Furthermore, the slope weeder 62 includes a slope conveyor belt 20, a second chain rod 22 and a second drive unit 21; the second drive unit 21 is connected to the slope conveyor belt 20; the slope conveyor belt 20 is arranged at an angle relative to the horizontal plane; a plurality of second chain rods 22 are arranged at intervals on the slope conveyor belt 20; the slope conveyor belt 20 includes a slope conveyor belt feed end 23 and a slope conveyor belt discharge end 24; the slope conveyor belt feed end 23 is located at one end of the slope conveyor belt 20, and the slope conveyor belt discharge end 24 is located at the other end of the slope conveyor belt 20; the height of the slope conveyor belt feed end 23 is higher than the slope conveyor belt discharge end 24; the screen conveyor belt discharge end 16 is located above the slope conveyor belt feed end 23; wherein, the slope conveyor belt 20 moves along the slope conveyor belt discharge end 24 toward the slope conveyor belt feed end 23.

[0043] Specifically, the potatoes on the screen conveyor belt 14 are transported to the screen conveyor belt discharge end 16 via the screen conveyor belt feed end 15, and then fall from the screen conveyor belt discharge end 16 and hit the slope conveyor belt feed end 23 on the slope conveyor belt 20. Due to the inclined setting of the slope conveyor belt 20 and the gravity of the potatoes, the potatoes fall from the slope conveyor belt feed end 23 to the slope conveyor belt discharge end 24. At the same time, since a plurality of second chain rods 22 are arranged at intervals on the slope conveyor belt 20, when roots and sand fall onto the slope conveyor belt 20, the roots and sand are transported along the movement direction of the slope conveyor belt 20 and are thrown out at the top of the slope conveyor belt 20, thereby further removing the roots and sand.

[0044] Furthermore, the annular lifting device 7 includes an annular elevator 2; the annular elevator 2 includes an outer conveyor belt 25, an inner conveyor belt 26, a third chain rod 28, a chain plate 31 and a third drive unit 27; the outer conveyor belt 25 includes an outer conveyor belt feed end 29 and an outer conveyor belt discharge end 30; the third drive unit 27 is connected to the outer conveyor belt 25 and the inner conveyor belt 26 respectively; a plurality of the third chain rods 28 are spaced apart on the outer conveyor belt 25; a plurality of the chain plates 31 are spaced apart on the third chain rod 28; the chain plates 31 include The chain strips 32 are enclosed; a plurality of the chain strips 32 are spaced apart and arranged on the chain plate 31; the outer conveyor belt 25 and the inner conveyor belt 26 are both annular in shape; the inner conveyor belt 26 is arranged on the opposite side of the outer conveyor belt 25, and the outer conveyor belt 25 and the inner conveyor belt 26 are together surrounded by the chain plate 31; the outer conveyor belt feed end 29 is located at one end of the outer conveyor belt 25, and the outer conveyor belt discharge end 30 is located at the other end of the outer conveyor belt 25; the slope conveyor belt discharge end 24 is located above the outer conveyor belt feed end 29.

[0045] Specifically, potatoes fall from the inclined conveyor belt discharge end 24 on the inclined conveyor belt 20 into the outer conveyor belt feed end 29, and are then transported in a circular motion surrounded by the outer conveyor belt 25 and the inner conveyor belt 26, and the chain plate 31 on the outer conveyor belt 25 can lift the potatoes upward; and since the chain plate bars 32 on the chain plate 31 are spaced apart to form gaps, and the third chain rod 28 is also spaced apart to form gaps, sand and soil can be continuously dropped from the potatoes as they pass through the entire circular route. The outer conveyor belt 25 and the inner conveyor belt 26 are both in the shape of a ring, which can greatly reduce the space occupied by the equipment and greatly increase the distance for removing impurities. The combination of the inner conveyor belt 26 and the outer conveyor belt 25 improves the stability of the potatoes in the circular transmission process and prevents the potatoes from falling and causing damage.

[0046] Furthermore, the annular lifting device 7 also includes a first-stage elevator 33; the first-stage elevator 33 includes a first conveyor belt 34 and a fourth drive unit 35; the first conveyor belt 34 includes a transmission vertical plate 36; a plurality of the transmission vertical plates 36 are arranged at intervals on the first conveyor belt 34; the first conveyor belt 34 is connected to the fourth drive unit 35; the first conveyor belt 34 includes a first conveyor belt feed end 37 and a first conveyor belt discharge end 38; the first conveyor belt discharge end 38 is movably connected to the first conveyor belt feed end 37 at an angle; the first conveyor belt feed end 37 is located below the outer conveyor belt discharge end 30.

[0047] Specifically, potatoes fall from the outer conveyor belt discharge end 30 into the first conveyor belt feed end 37, and are then transferred to the first conveyor belt discharge end 38 by the first conveyor belt 34 and the transmission vertical plate 36; the first conveyor belt discharge end 38 and the first conveyor belt feed end 37 are angularly movably connected so that the angle between the first conveyor belt discharge end 38 and the first conveyor belt feed end 37 can be adjusted to adjust the height of the first conveyor belt 34. By adjusting the height of the first conveyor belt 34, the height of the potato conveying can be adjusted, and the transmission vertical plate 36 enables the potatoes to be conveyed along the first conveyor belt 34 with a slope.

[0048] Furthermore, the V-belt conveying device 59 includes a material distributor 39 and a V-belt conveyor 3; the V-belt conveyor 3 includes two second conveyor belts 8 and a V-belt conveyor drive unit 9; the V-belt conveyor drive unit 9 is respectively connected to the two second conveyor belts 8; the two second conveyor belts 8 are arranged at an interval and tilted; the material distributor 39 includes a triangular conveyor belt 40, a moving component 41 and a channel component 42; the channel component 42 includes multiple channels 43; the triangular conveyor belt 40 is connected to the moving component 41; the channel component 42 is located below the triangular conveyor belt 40 and the moving component 41; the first conveyor belt discharge end 38 is located above the triangular conveyor belt 40; the channel 43 is located on one side of the feed end of the V-belt conveyor 3.

[0049] Specifically, potatoes fall from the discharge end 38 of the first conveyor belt onto the triangular conveyor belt 40. The moving assembly 41 is used to drive the triangular conveyor belt 40 to move. Driven by the moving assembly 41, the triangular conveyor belt 40 performs a reciprocating motion, causing the potatoes to evenly fall onto the multiple channels 43 of the channel assembly 42, dispersing the potatoes and preventing them from clumping together. The potatoes that fall onto the multiple channels 43 then fall onto the multiple V-belt conveyors 3, allowing the potatoes to be individually and standardizedly arranged and further cleaned. This standardized arrangement facilitates the subsequent image capture mechanism 10 to sequentially photograph the individual potatoes and impurities. The V-belt conveyor drive unit 9 in the V-belt conveyor 3 drives the two second conveyor belts 8. The two second conveyor belts 8 are arranged at an angle to allow the potatoes to be transported one after another in a queue. The angled arrangement between the two second conveyor belts 8 allows impurities to fall through the gap between the two second conveyor belts 8, thereby screening out some impurities.

[0050] Furthermore, the rejection and screening device 60 includes a brush chain conveyor 44 and a rejection and screening machine 4; the rejection and screening machine 4 includes an image acquisition mechanism 10, a sorting mechanism 11, an industrial computer and a third conveyor belt 13; the image acquisition mechanism 10 is arranged on the third conveyor belt 13; the sorting mechanism 11 is located on one side of the discharge end of the third conveyor belt 13; the image acquisition mechanism 10 is connected to the industrial computer, and the industrial computer is connected to the sorting mechanism 11; the brush chain conveyor 44 includes a fifth drive unit 45 and a fourth conveyor belt 46; the fifth drive unit 45 is connected to the fourth conveyor belt 46; the fourth conveyor belt 46 includes a brush plate 47; the brush plate 47 is evenly arranged on the fourth conveyor belt 46; the discharge end of the brush chain conveyor 44 is located on one side of the feed end of the rejection and screening machine 4; the feed end of the brush chain conveyor 44 is located on one side of the discharge end of the V-belt conveyor 3.

[0051] Specifically, potatoes fall from the discharge end of the V-belt conveyor 3 onto the fourth conveyor belt 46 of the brush chain conveyor 44. The fifth drive unit 45 is used to drive the fourth conveyor belt 46. Since the brushes on the brush plate 47 on the fourth conveyor belt 46 have appropriate flexibility, the potatoes will quickly sink into them, and the potatoes will become stable from their original flipping state in the air. When the potatoes are trapped in the brushes, part of the potato body will be wrapped by the brush plate 47 and carried by the brush plate 47 for operation, so that the potatoes will not slip or bounce in place, so they can be quickly conveyed. When the potatoes are transported to the exit, they will fall off the brush due to their own gravity and then enter the rejection and screening machine 4 to provide a stable object state for the image acquisition mechanism 10 to perform image acquisition. The image acquisition mechanism 10 in the rejection and screening machine 4 acquires images of impurities and potatoes, and after the images are acquired, they are uploaded to the industrial computer, which controls the sorting mechanism 11 located at the discharge end of the third conveyor belt 13 according to the images to accurately remove the impurities on the third conveyor belt 13.

[0052] Furthermore, the image acquisition mechanism 10 includes a first sensor 12 and a camera 58; the sorting mechanism 11 includes a second sensor 19, a sorting flap 5 and a flap motor 6; the first sensor 12, the camera 58, the second sensor 19 and the flap motor 6 are all connected to the industrial computer; the sorting flap 5 is connected to the flap motor 6; the sorting flap 5 is located on one side of the discharge end of the third conveyor belt 13.

[0053] Specifically, potatoes and other debris are transported by the third conveyor belt 13 and queued. When they enter the range of the image acquisition mechanism 10 in an orderly manner, the first sensor 12 is triggered, and the first sensor 12 sends a signal to the industrial computer, which triggers the camera 58 to capture images. After the image is captured, the industrial computer system will instantly identify whether the material passing through the range of the image acquisition mechanism 10 is potatoes or other debris, and generate instructions for controlling the action of the sorting flap 5 in the system. When potatoes or debris pass through the second sensor 19, an instruction for the flap action is issued to control the action of the flap motor 6. When potatoes pass through the sorting flap 5, the potatoes will pass over the sorting flap 5, and when other debris pass through the sorting flap 5, the sorting flap 5 will flip over, and the debris will be blocked by the sorting flap 5 and fall off, thereby being discharged out of the machine.

[0054] Furthermore, the combined intelligent harvester also includes a cache discharger 48; the cache discharger 48 includes a steering conveyor belt 49, a steering switching mechanism 50 and two cache discharge conveyor belts 51; the steering conveyor belt 49 is connected to the steering switching mechanism 50; the steering conveyor belt 49 is located on the opposite side of the two cache discharge conveyor belts 51; the feed end of the steering conveyor belt 49 is located on the side of the discharge end of the rejection screening machine 4.

[0055] Specifically, the steering switching mechanism 50 is used to drive the steering conveyor belt 49 to steer. After potatoes are removed from the screening machine 4 and enter the steering conveyor belt 49, they are then transported to the buffer discharge conveyor belt 51. The alternating operation of the two buffer discharge conveyor belts 51 creates an idle period at the combined intelligent harvester's discharge terminal, allowing the machine ample time to switch to loading bags of potatoes without requiring downtime, thus ensuring the combined intelligent harvester's harvesting efficiency. The specific buffer discharge process is as follows: During a belt change, the previously operating buffer discharge conveyor belt 51 stops, and the other buffer discharge conveyor belt 51 begins operating. The steering switching mechanism 50 then drives the steering conveyor belt 49 to steer in the direction of the other buffer discharge conveyor belt 51, transferring the potatoes to the active buffer discharge conveyor belt 51. The belt change is completed before the potatoes completely cover the active buffer discharge conveyor belt 51. After the belt change, the active buffer discharge conveyor belt 51 remains in operation; the previously stopped buffer discharge conveyor belt 51 begins operating and then stops after a specified time. When the ton bag is full, repeat the above process to achieve the effect of no shutdown.

[0056] Furthermore, the combined intelligent harvester also includes a ton bag collecting machine 52; the ton bag collecting machine 52 includes: a loading fork 53, a loading fork lifting unit 54, a load pallet 55, a load pallet lifting unit 56, a load pallet pulling unit 57 and a control unit; the loading fork 53 is connected to the loading fork lifting unit 54; the load pallet 55 is located below the loading fork 53, and the load pallet 55 is connected to the load pallet lifting unit 56 through the load pallet pulling unit 57; the control unit is respectively connected to the loading fork lifting unit 54, the load pallet pulling unit 57 and the load pallet lifting unit 56; the ton bag collecting machine 52 is located on one side of the cache discharger 48.

[0057] Specifically, the potatoes from the buffer discharger 48 are finally collected by the ton bag collector 52. The control unit is specifically an industrial computer. A carrying tray 55 is positioned below the loading fork 53, allowing the ton bag to be hung on the loading fork 53 and supported by the carrying tray 55. The control unit (not shown) controls the slow downward movement of the carrying tray lifting unit 56, which in turn drives the carrying tray 55 downward, ensuring a substantially constant drop height for the potatoes, preventing damage due to excessively high feed heights. When the carrying pallet lifting unit 56 moves down to the bottom, the control unit controls the carrying pallet pulling unit 57 to pull out the carrying pallet 55 and no longer support the ton bag. Then, when the ton bag filled with potatoes hanging on the loading fork 53 reaches the specified weight, the pressure sensor on the loading fork 53 detects that the ton bag filled with potatoes has reached the specified weight and uploads it to the control unit. The control unit controls the loading fork lifting unit 54 to descend rapidly. The rapid descent of the loading fork lifting unit 54 drives the loading fork 53 to descend rapidly, causing the ton bag to touch the ground, thereby completely loosening the belt of the ton bag. At this time, the harvester is still moving at a constant speed, and the ton bag is separated from the loading fork 53, thereby realizing automatic unloading without stopping for unloading.
