[0051] In a typical embodiment of the present application, as shown in Figures 1-4 A self-adaptive efficient intelligent lotus root harvesting and sorting integrated machine is provided, which comprises a shovel conveying device 100, a sorting device 600, a jet flushing mechanism 500, a cutting device 200, a lifting mechanism 300, a box storage mechanism 700, a box changing mechanism 800, and a power device 400. The power device 400 is located at the bottom to provide power for the whole machine. The lifting mechanism 300 is installed at the top of the power device. The shovel conveying device 100 is connected with the lifting mechanism 300. The jet flushing mechanism 500 is connected with the power device 400. The bottom of the cutting device 200 is connected with the power device 400. The sorting device 600 is connected with the lifting mechanism 300. The box changing mechanism 800 is connected with the frame on the left and right sides. The box changing mechanism 800 is installed with the box storage mechanism 700 at the front end.

[0052] As shown in Figure 7 The power device 400 comprises a frame, a power mechanism, and two walking mechanisms. The frame comprises a frame frame 410. The frame frame is connected with the walking mechanism on both sides at the bottom and is upwardly extended by the walking mechanism. The power mechanism is arranged on the frame. The power mechanism is connected with the walking mechanism to provide power for the walking mechanism.

[0053] In an optional embodiment, the walking mechanism adopts a caterpillar walking mechanism 430. Two caterpillar walking mechanisms 430 are arranged correspondingly on both sides of the frame.

[0054] A load-bearing platform 440 is arranged correspondingly between the walking mechanisms at the rear of the frame frame 410. The load-bearing platform 440 is used to provide installation space to install the box storage mechanism and the box changing mechanism.

[0055] In a preferred embodiment, a gathering mechanism 420 is fixedly arranged at the front end of the frame frame 410 on both sides. The gathering mechanism 420 is arranged correspondingly behind the cutting device 200 and on both sides of the shovel conveying device 100, which can guide and gather the lotus roots to the shovel conveying device 100. The gathering mechanism 420 comprises an inclined gathering plate, which is fixedly arranged on both sides of the front end of the frame frame. The gathering plate is inclined upwardly and inclined toward the shovel conveying device 100, that is, the gathering plate is arranged inwardly, which is convenient for gathering the lotus roots to the shovel conveying device.

[0056] A hollow buoyancy plate can be installed at the bottom of the power unit. Specifically, the hollow buoyancy plate is installed at the bottom of the frame to form a semi-floating lotus root digger. This is used to reduce the pressure of the integrated machine on the lotus pond. The power unit facilitates the movement of the lotus root digger in the lotus pond and maintains stability.

[0057] The cutting device 200 is connected to the frame of the power unit 400; for example... Figure 6 As shown, the cutting device 200 includes a cam 210, a first blade 220, a second blade 230, a first drive motor 240, and a connecting frame 250. The first blade and the second blade are both horizontally arranged. The second blade 230 is fixedly arranged. The first blade 220 can move horizontally back and forth to perform cutting.

[0058] Specifically, the second blade 230 is fixedly mounted on the connecting frame 250, and the connecting frame 250 is fixed to the frame of the power unit 400.

[0059] The first blade 220 is connected to the cam 210 via a connecting rod, and the first drive motor 240 drives the cam 210 to rotate via a chain. Specifically, the first drive motor 240 is connected to the drive sprocket of the sprocket transmission mechanism. The sprocket transmission mechanism consists of a drive sprocket, a driven sprocket, and a chain. The driven sprocket rotates under the drive of the chain. The driven sprocket is connected to the wheel axle of the cam 210, thereby driving the cam 210 to rotate.

[0060] The protruding part of the cam 210 is hinged to one end of the connecting rod, and the other end of the connecting rod is hinged to the root of the first blade 220. Specifically, a fixed rod is provided at the root of the first blade 220, one end of the connecting rod is hinged to the protruding part of the cam, and the other end of the connecting rod is hinged to the fixed rod. When the cam rotates, the first blade can be driven to reciprocate in the horizontal direction via the connecting rod.

[0061] Both the first and second blades include multiple blade bodies arranged adjacent to each other in sequence, with the cutting ends of the blade bodies being rounded.

[0062] This cutting device achieves precise reciprocating cutting driven by a unidirectional motor rotation, reducing costs and improving mechanical accuracy. It is used to cut lotus leaves and stalks in lotus ponds, providing a cleaner harvesting environment for subsequent retrieval.

[0063] The jet flushing mechanism 500 is installed in front of the shovel conveyor and behind the cutting device, and is connected to the power unit 400 frame.

[0064] like Figure 9As shown, the jet flushing mechanism 500 includes a gearbox 510, a connecting frame 520, a pusher plate 530, and a jet frame 540. The jet frame 540 is mounted on the frame of the power unit, and the pusher plate 530 is placed at the front end of the jet frame 540. The connecting frame is provided in the jet frame, and a nozzle frame is installed on the connecting frame 520. Multiple high-pressure nozzles are arranged on the nozzle frame, and the nozzle frame can move up and down and left and right to adjust the range of nozzle flushing.

[0065] The push plate 530 is used to push away debris such as lotus leaves and stalks that are cut off by the front cutting device and float on the water surface, providing a cleaner salvage environment for the rear. The push plate 530 has multiple small openings to allow water to flow through as the lotus root digger moves forward. The pressure of the water flowing through the openings helps to attract impurities on the water surface to the push plate. Inclined plates are installed on both sides of the push plate 530 to prevent large debris from entering the salvage area from the sides.

[0066] Specifically, the jet frame 540 is equipped with a gearbox 510, and the gear in the gearbox 510 meshes with the rack on the connecting frame 520. The rack is horizontally positioned, and the meshing of the gearbox and the rack enables the connecting frame to drive the nozzle frame to move left and right for rinsing. Of course, in other examples, the positions of the gearbox and rack in the jet frame and the connecting frame can be interchanged, with the gearbox placed on the connecting frame and the rack placed on the jet frame. The connecting frame is fixedly equipped with a vertical lead screw, which is connected to the nozzle frame. The lead screw can rotate to drive the nozzle frame to rise and fall, thereby increasing the rinsing range and applicability, and improving the rinsing efficiency.

[0067] The lead screw can be connected to the gear above the connecting frame. The gear is driven to rotate by a power device, which in turn drives the lead screw to rotate, thus enabling the nozzle frame to move up and down.

[0068] Understandably, in order for the high-pressure nozzle to effectively flush the mud around the lotus roots in the lotus pond, the height of the nozzle holder and the angle of the high-pressure nozzle can be designed. Since the nozzle holder can move up, down, left, and right, it drives the high-pressure nozzle to expand the flushing range, which can fully disperse the mud around the lotus roots.

[0069] Among them, such as Figure 5 As shown, the shovel-type conveying device 100 includes fixed frames 120 on both sides, gears 130, connecting rods 140, and shovel-type lifting plates 150. Multiple shovel-type lifting plates 150 are arranged in a ring, which is similar to the ring formed by the chain in a sprocket and chain mechanism. Each shovel-type lifting plate 150 is connected to gears 130 at both ends. Adjacent shovel-type lifting plates 150 are hinged to each other by connecting rods 140, and the gears 130 at the ends of adjacent shovel-type lifting plates 150 mesh with each other.

[0070] A shovel-type lifting plate 150 is disposed between fixed frames 120, which are used to install gears, etc.

[0071] Specifically, a rotating shaft is arranged at the bottom of each shovel lifting plate 150, gears 130 are arranged at both ends of the rotating shaft, the rotating shafts of adjacent shovel lifting plates 150 are connected by connecting rods 140, and the connecting rods 140 are hinged to the rotating shafts; the gears 130 at the ends of the plurality of shovel lifting plates are also sequentially meshed to form a ring, each gear 130 is not rotated after being meshed and installed, but forms an entirety, and under the driving of the corresponding power, the gears 130 are circularly rotated in a form similar to a chain to drive the shovel lifting plate 150 to rotate, so that the lotus roots are lifted.

[0072] The shovel lifting plate 150 is L-shaped, and the entire shovel conveying device 100 is arranged in an upward inclined manner.

[0073] In an optional embodiment, the overall lifting power of the shovel conveying device is driven by a first transmission gear 110, the first transmission gear 110 is connected to a motor or the like through a transmission mechanism, the first transmission gear 110 can be connected to a power gear located inside the fixed frame 120 through an axle, the power gear is meshed with the gears 130 at the ends of the shovel lifting plates, and the gears 130 are driven to circularly rotate by the power gear.

[0074] The shovel conveying device can realize the same-direction salvage of the lotus roots, and facilitates further processing by the rear mechanism.

[0075] The sorting device 600 is arranged behind the shovel conveying device 100, and the shovel conveying device 100 conveys the lotus roots to the sorting device 600 for sorting; as shown in Figure 8 The sorting device 600 includes a guide groove 610, a sorting frame 620, a clamping groove conveying belt 630, a second transmission gear 640, and a baffle 650; the clamping groove conveying belt 630 is arranged between the two sorting frames 620, and the clamping groove conveying belt 630 is driven to rotate by the second transmission gear 640, and the second transmission gear can be connected to a motor or the like.

[0076] A plurality of clamping grooves are arranged on the clamping groove conveying belt, and one groove can accommodate one lotus root; the clamping groove conveying belt includes a plurality of conveying belt structures arranged side by side, each conveying belt structure is provided with a plurality of clamping grooves, the clamping grooves of adjacent conveying belt structures are arranged one by one in correspondence, and the lengths of the plurality of conveying belt structures are different, so that short lotus roots can be stored at the end of the short conveying belt structure, and long lotus roots can be stored at the end of the long conveying belt structure, thereby achieving sorting.

[0077] The guide groove 610 is fixedly arranged at the front end of one side sorting frame 620, and the baffle 650 is fixedly arranged at the side of the other side sorting frame 620, and the baffle 650 is arranged along the length direction of the sorting frame 620; the clamping groove conveying belt and the like of the entire sorting device 600 are inclined toward the sorting frame with the fixed baffle, that is, the sorting frame with the fixed baffle is lower in height than the other sorting frame; the short conveying belt structure is arranged close to the baffle.

[0078] In the embodiment, the guide groove 610 is fixed to the front end of the left sorting frame 620, and the baffle 650 is fixed to the right sorting frame 620; the device is inclined to the right by 30°, the characteristics of the one-slot-one-leaf-petal of the clamping groove conveying belt are utilized, and the centers of gravity of the lotus petals of different lengths are different after being inclined by 30°, so that the sorting is realized; the small lotus petals and the broken lotus petals are lifted out in advance at the end of the short conveying belt structure during the conveying process, and the long lotus petals are dropped to the rear end of the long conveying belt structure for packaging.

[0079] In the optional embodiment, a flexible bottom plate is arranged on the clamping groove conveying belt, the flexible bottom plate can be provided with an opening, and a spray head can be arranged in the opening; when the clamping groove conveying belt is running, the lotus petal moves and rubs against the flexible bottom plate, so that the lotus petal rolls on the clamping groove conveying belt, and the flexible bottom plate spray head sprays water to clean the lotus petal in 360 degrees. The sorting device cleans and sorts the lotus petal salvaged, reduces the labor cost, and improves the quality of the harvested lotus petal.

[0080] The box storage mechanism 700 is arranged on the side of the sorting device 600; as shown in Figure 11 The box storage mechanism 700 includes a box receiving frame 710, a pushing plate 720, a slide 730, a connecting frame 740, and an air pump 750; the box receiving frame 710 is arranged on the top of the connecting frame 740, the pushing plate 720 is arranged on the lower side of the box receiving frame 710, and the pushing plate 720 is fixedly connected with the air pump 750; the air pump is arranged behind the box receiving frame, and the air pump can drive the pushing plate to move; the lower side of the box receiving frame is provided with a pushing opening, the length and width of the pushing plate are smaller than the length and width of the pushing opening of the box receiving frame, the pushing plate corresponds to the pushing opening, and the pushing plate can be moved to the pushing opening to push the box out; the slide 730 is arranged on the side of the connecting frame 740, and the slide 730 is arranged at the pushing opening of the box receiving frame in a corresponding manner; and the slide is arranged in a downward inclined manner.

[0081] The box receiving frame of the box storage mechanism can accommodate empty boxes, and the empty boxes are vertically stacked and arranged in the box receiving frame; the air pump drives the pushing plate to push the empty box at the bottom out of the pushing opening through the slide. After the lower box is pushed out, the upper box will fall due to gravity, and the next pushing out can be performed. The box storage mechanism 700 solves the problem of space occupation when the boxes are stored horizontally, saves the horizontal space, realizes the vertical stacking of the boxes, and improves the space utilization rate.

[0082] The box changing mechanism 800 is arranged at the end of the sorting device 600 and can receive the long lotus petal sorted by the sorting device 600; as shown in Figure 12As shown, the box-changing mechanism 800 includes a third transmission gear 810, a second worm gear 820, a guide plate 830, an air pump clamp 840, and a buffer plate 850. The second worm gear 820 meshes with a worm wheel at the bottom of the air pump clamp 840. The power of the second worm gear is transmitted through the third transmission gear 810, which is connected to a motor, etc. The air pump clamp 840 has an openable and closable gripper, which is driven to open and close by an air pump. The guide plate 830 is fixed behind the air pump clamp 840 and is inclined downward. The buffer plate 850 is placed on the right side of the air pump clamp and is inclined upward. The buffer plate is correspondingly set at the end of the sorting device 600 to buffer and protect the lotus roots that fall from the sorting device and to serve as a slide to feed them into the box clamped by the air pump clamp.

[0083] Driven by a worm gear, the air pump clamp rotates to face the push port of the storage mechanism, clamping the boxes pushed out by the mechanism. It then rotates and moves to the position to receive lotus roots, between the buffer plate and the air pump clamp. Lotus roots enter the boxes via the buffer plate at the end of the sorting device. Once the box is full, the air pump clamp rotates to position 830 on the guide plate and gently pushes it into the water. The air pump clamp then returns to its original position, grabs the next box, and repeats the process. This box-changing mechanism automatically replaces the lotus root boxes, saving labor costs and improving the automation level of the machinery.

[0084] The power unit 400 has lifting mechanisms 300 installed above both traveling mechanisms, which are connected to the vehicle frame.

[0090] The first blade of the cutting device 200 reciprocates to cut lotus root stems and leaves in the lotus pond, so as to provide a good working environment for the rear salvage; the push plate 530 of the jet flushing mechanism 500 pushes away floating objects on the water surface, the nozzle frame of the jet flushing mechanism adjusts up and down and left and right, expands the area of lotus root flushing, the high-pressure nozzles on the nozzle frame disperse the soil around the lotus roots, after being sprayed by the high-pressure water flow, the lotus roots in the lotus pond float out of the water surface, the lotus roots floating up are lifted upward by the shovel lifting plate 150 of the shovel type conveying device 100 to realize the salvage of the lotus roots on the water surface; the sorting device receives the salvaged lotus roots through the guide chute, and one lotus root is realized in one slot of the clamping groove conveyor belt, the clamping groove conveyor belt is inclined at a certain angle, and the sorting is performed by using the different centers of gravity to sort the lotus roots, the small lotus seedlings and part of the broken lotus roots are removed, the long lotus roots with good quality are screened, the long lotus roots after screening are sent into the box body clamped by the air pump by the buffer plate of the box changing mechanism 800, and after the box is filled, the box changing mechanism rotates to put the lotus root filled box into water; the new empty box is pushed out by the box storage mechanism, and after the new box is clamped by the box changing mechanism, the box changing mechanism rotates to the lotus root receiving position to receive the lotus roots.

[0091] The lifting mechanism is driven by the double worm gear transmission and the meshing of the worm gear and the rack, and the corresponding working mechanism is lifted along the rack load bearing rod by rotating the first worm driven by the motor, so as to adapt to the working environment of different depths of water surface.

[0092] The integrated machine can realize lotus root digging, fishing, sorting and loading in an integrated manner, improves the automation degree, and greatly reduces the labor cost. The integrated machine can adjust the flushing range of the lotus root, can not only flush the lotus root at the best position, but also can harvest, sort and store multiple lotus roots, solves the problems of unstable work, low automation degree and poor environmental adaptability of the traditional lotus root digging machine through a mechanical structure, and can be applied to water areas of different depths, and can complete the lotus root harvesting work in the environment with high silt content such as ponds and wetlands.
