Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limitations on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0032] The technical solution of the present invention is further described in detail below through specific embodiments and in conjunction with the accompanying drawings:

[0033] Example 1

[0034] like Figure 1 , 2 As shown, a leek bundling device includes a bundling platform 51 for placing the leek bundling, a paper tape conveying device 52 for conveying the paper tape for bundling the leek, a guiding structure 55 for guiding the paper tape to move around the leek, and a conjugate cam mechanism 54 for supporting, cutting and welding the paper tape. The guiding structure 55 is installed on the bundling platform 51, and the inner side surface of the guiding structure 55 has a guiding groove 551. The conjugate cam mechanism 54 is located below the bundling platform 51, and the conjugate cam mechanism 54 includes a first rotating shaft 541 and a driving mechanism for driving the first rotating shaft 541 to rotate. The first driving assembly 548, the first rotating shaft 541 is sequentially mounted with the first cam 542, the second cam 543 and the third cam 544, the bundling table 51 is slidably connected with the supporting member 545, the cutting member 546 and the welding member 547 in the vertical direction at the positions corresponding to the first cam 542, the second cam 543 and the third cam 544, respectively, and the lower ends of the supporting member 545, the cutting member 546 and the welding member 547 are slidably connected with the outer peripheral surfaces of the first cam 542, the second cam 543 and the third cam 544 respectively. The bundling device is used to bundle the harvested leeks. When the leeks are transported to the bundling platform 51, the paper tape conveying device 52 transports the paper tape for bundling to the bundling platform 51, and the paper tape moves along the guide groove 551 on the guide structure 55, and finally surrounds the leeks on the bundling platform 51. A conjugate cam mechanism 54 is arranged below the bundling platform 51 to rotate, and a first driving assembly is arranged on the conjugate cam mechanism 54. The first driving assembly drives the first rotating shaft 541 to drive the first cam 542, the second cam 543 and the third cam 544 to rotate. The rotating first cam 542, the second cam 543 and the third cam 544 rotate to lift the supporting member 545, the cutting member 546 and the welding member 547 in turn to contact the paper tape on the bundling platform 51, so as to realize the supporting, cutting and welding functions of the paper tape, and the paper tape is cut and welded together, so that the paper tape can firmly bind the leeks without being scattered. Then the leeks are removed from the bundling platform 51, and the bundling device continues to bundle the next bunch of leeks.

[0035] like Figure 1As shown, the bundling device further includes a second driving component 53. The guiding structure 55 is in an n-shaped structure, with the opening of the guiding structure 55 facing the bundling table 51. The second driving component 53 is connected to the guiding structure 55 to drive the guiding structure 55 to move closer to or away from the bundling table 51 in the vertical direction. When bundling, the paper tape moves along the upper surface of the bundling table 51 and the guiding groove 551 on the guiding structure 55. Since it is necessary to guide the paper tape to go around the leeks once, the guiding structure 55 and the bundling table 51 need to form a closed structure around the leeks. Therefore, the guiding structure 55 is in an n-shaped structure. When the guiding structure 55 contacts the bundling table 51, the guiding structure 55 and the bundling table 51 together form a "square" structure to guide the paper tape to move along the inner side of the "square" structure. And the "square" structure is a closed structure, and the leeks cannot directly move to the inner side of the "square" structure to be bundled by the paper tape. Therefore, the bundling device further includes a second driving component 53. The second driving component 53 can drive the guiding structure 55 to move in the direction away from or closer to the bundling table 51. When the guiding structure 55 moves away from the bundling table 51, there is a gap between the guiding structure 55 and the bundling table 51, and the leeks can move into or out of the inner side of the "square" structure from the gap. When the guiding structure 55 approaches the bundling table 51 until it contacts the bundling table 51, the guiding structure 55 and the bundling table 51 form a closed "square" structure to guide the movement direction of the paper tape.

[0036] As Figure 3As shown, the second driving assembly 53 includes a lifting rack 531 connected to the guide structure 55, a first reciprocating gear 532, a second reciprocating gear 533, a rocker rod 534, a first gear rod 535 and a second gear rod 536. The lifting rack 531 is meshed with the first reciprocating gear 532, and the first reciprocating gear 532 is meshed with the second reciprocating gear 533. One end of the rocker rod 534 is rotatably installed between the first reciprocating gear 532 and the second reciprocating gear 533 and is transmission-connected to the first driving assembly 548. The first gear rod 535 is fixed on a side of the first reciprocating gear 532 facing the rocker rod 534. The second gear rod 536 is fixed on a side of the second reciprocating gear 533 facing the rocker rod 534. The other end of the rocker rod 534 is provided with a protrusion 537 protruding in the direction of the first reciprocating gear 532 and the second reciprocating gear 533 for driving the first gear rod 535 and the second gear rod 536 to rotate. When the second driving assembly 53 is working, the swing rod 534 rotates, and the protrusion 537 on the swing rod 534 first contacts the first gear rod 535, and the first gear rod 535 and the swing rod 534 rotate clockwise, thereby driving the first reciprocating gear 532 to rotate clockwise, thereby driving the lifting rack 531 to drive the guide structure 55 to move upward. When the swing rod 534 rotates to a certain position, the protrusion 537 of the swing rod 534 is out of contact with the first gear rod 535, and then contacts the second gear rod 536, and the second gear rod 536 rotates clockwise, thereby driving the second reciprocating gear 533 to rotate clockwise, and the second reciprocating gear 533 is meshed with the first reciprocating gear 532, and the second reciprocating gear 533 drives the first reciprocating gear 532 to rotate counterclockwise, thereby driving the lifting rack 531 to move downward, and finally causing the guide structure 55 to move downward.

[0037] like Figure 3 , 4As shown, the first driving assembly 548 also includes a driving wheel 5481 installed on the first rotating shaft 541, a transmission gear 538 is provided at the rotating end of the swing rod 534, and a transmission member 549 is also provided. The transmission member 549 includes a full gear 5491 and a half gear 5492. The full gear 5491 and the half gear 5492 are coaxially connected, the full gear is transmission-connected to the first driving assembly 548 5491, and the half gear 5492 is meshed with the transmission gear 538. Considering the need to reduce the driving source as much as possible and ensure the precise matching between the conjugate cam mechanism 54 and the guide structure 55, the second driving assembly 53 is not provided with a power source. The power of the second driving assembly 53 is provided by the first driving assembly 548 that drives the conjugate cam mechanism 54 to rotate, and the power is transmitted between the first driving assembly 548 and the second driving assembly 53 through the transmission member 549. The transmission member 549 includes a coaxial half gear 5492 and a full gear 5491. The rotating end of the swing rod 534 is provided with a transmission gear 538. The half gear 5492 meshes with the transmission gear 538. The first rotating shaft 541 is also provided with a driving wheel 5481. The full gear 5492 is connected to the driving wheel 5481 in a transmission manner, so that the first rotating shaft 541 rotates one circle and the second driving component 53 works half a cycle.

[0038] Example 2

[0039] like Figure 5 As shown, a leek harvester includes the leek bundling device 5 in the above-mentioned embodiment 1, and also includes a powered vehicle body 1, a gathering and harvesting device 2, a conveying device 3 and a bundling device 4. The gathering and harvesting device 2, the conveying device 3, the bundling device 4 and the bundling device 5 are all installed on the vehicle body 1. The gathering and harvesting device 2 is installed at the front end of the vehicle body 1. The two ends of the conveying device 3 are respectively aligned with the discharge port of the gathering and harvesting device 2 and the feed port of the bundling device 4. The bundling device 5 is installed on one side of the bundling device 4. When harvesting leeks, the vehicle body 1 is aimed at the leeks planted in the field. The vehicle body 1 itself has power and can drive the leek harvester to move forward. The front end of the vehicle body 1 is provided with a gathering and harvesting device 2. As the vehicle body 1 moves forward, the leeks enter the gathering and harvesting device 2 and are gathered and harvested by the gathering and harvesting device 2. The harvested leeks are discharged from the discharge port of the gathering and harvesting device 2 and enter the conveying device 3. The conveying device 3 conveys the harvested leeks to the bundling device 4. The bundling device 4 bundles the harvested leeks into multiple bundles. A bundling device 5 is provided next to the bundling device 4. When the leeks are conveyed to the bundling device 5, the leeks bundled by the bundling device 4 are bundled, thereby achieving preliminary packaging of the harvested leeks.

[0040] like Figure 5As shown, the gathering and harvesting device 2 includes two gathering plates 21 arranged opposite to each other, the gathering plates 21 are fixed to the front end of the vehicle body 1 and aligned with the entrance of the conveying device 3, the two gathering plates 21 are arranged in an outward-facing "eight" shape, and a harvesting channel 23 is formed between the two gathering plates 21, a harvesting device 22 is arranged below the gathering plates 21, and the rear of the harvesting channel 23 is aligned with the feed inlet of the conveying device 3. The gathering plates 21 arranged in an outward-facing "eight" shape enable the gathering and harvesting device 2 to have a larger entrance, so that a larger area of ​​leeks can be gathered for harvesting. When the leeks are gathered by the gathering plates 21, as the vehicle body 1 moves forward, the leeks enter the harvesting device 22 below the gathering plates 21, and the leeks are cut by the harvesting device 22 and output to the conveying device 3 from the rear of the harvesting channel 23. The two gathering plates 21 are inclined toward the front and lower part of the vehicle body 1. Since the roots of the leeks planted in the ground are relatively concentrated near the ground, while the leaves at the upper end are relatively dispersed, the leaves of different bundles of leeks are intertwined and difficult to separate, so when gathering, the roots near the ground should be operated. Therefore, the two gathering plates 21 are inclined toward the front and lower part of the vehicle body 1 to gather the roots of the leeks to be harvested.

[0041] like Figure 6 As shown, the harvesting device 22 includes a bottom plate 221, which is installed at the front end of the vehicle body 1 and located at the rear and lower part of the gathering plate 21. A first cutting knife 222 is fixed at the front end of the bottom plate 221, and a second cutting knife 223 is slidably connected to the bottom plate 221. A rocker mechanism 224 and a third driving member 225 are also provided on the bottom plate 221. The third driving member 225 is fixed on the bottom plate 221, one end of the rocker mechanism 224 is connected to the third driving member 225, and the other end of the rocker mechanism 224 is connected to the second cutting knife 223. The first cutting knife 222 and the second cutting knife 223 form a scissor-like structure, wherein the first cutting knife 222 is fixed, and the second cutting knife 223 moves relative to the first cutting knife 22 to cut the leeks entering between the first cutting knife 222 and the second cutting knife 223. The third driving member 225 provides power for the rocking mechanism 224, and the rocking mechanism 224 drives the second cutting knife 223 to reciprocate. A lifting device is also provided on the bottom plate 221, and the lifting device includes a rack 226 and a fourth driving member 227. The rack 226 is vertically fixed on the bottom plate 221, and the fourth driving member 227 is fixed on the vehicle body 1. The fourth driving member 227 is provided with a gear 228, and the gear 228 is meshed with the rack 226. The lifting device can lift the bottom plate 221 to different heights to adapt to different terrains or adjust the height of harvesting leeks. The lifting device includes a rack 226 and a fourth driving member 227. The fourth driving member 227 is provided with a gear 228 meshed with the rack 226. The fourth driving member 227 can drive the rack 226 to move up and down through the gear 228 to adjust the height of the bottom plate 221.

[0042] like Figure 7As shown, a reel 211 is rotatably mounted on the gathering plate 21, and a first driven gear is fixedly arranged on the reel 211. A driving gear is connected to the driving shaft of the transmission device 3, and the first driven gear is meshed with the driving gear. The reel 211 can move the leeks into the gathering and harvesting device 2 more quickly, and the reel 211 can change the movement direction of the leeks by moving the leeks, so that the leeks can enter the transmission device 3 smoothly. The reel 221 is connected to the driving gear on the transmission device 3 through the first driven gear, and the transmission device 3 provides a power source for the rotation of the reel 211.

[0043] Example 3

[0044] This embodiment is similar to the above-mentioned embodiment 2, except that: Figure 8 As shown, the conveying device 3 includes a front belt roller 31, a rear belt roller 32, a conveyor belt 33 and a fifth driving member 34. Two front belt rollers 31 are provided. The two front belt rollers 31 are respectively vertically arranged on both sides of the discharge port of the gathering and harvesting device 2. The rear belt roller 32 is arranged in the horizontal direction. The two rear belt rollers 32 correspond to the two front belt rollers 31 one by one. The two conveyor belts 33 are respectively wound around the corresponding front belt rollers 31 and the rear belt rollers 32 in sequence. A conveying channel 35 for conveying leeks is formed between the two conveyor belts 33. The output end of the fifth driving member 34 is connected to the rear belt roller 32 to drive the conveyor belt 33 to drive the leeks to move along the conveying channel 35 and transform the leeks from a vertical state to a horizontal state. The fifth driving member 34 provides power for the rotation of the front belt roller 31. Two front belt rollers 31 are provided, which are respectively arranged vertically on both sides of the discharge port of the gathering and collecting device 2. The front belt rollers 31 are perpendicular to the plane where the two gathering plates 21 are located.

The front belt rollers 31 are perpendicular to the plane where the two gathering plates 21 are located, so that the conveying channel 35 between the two front belt rollers 21 is also perpendicular to the plane where the two gathering plates 21 are located, which is adapted to the movement state of the leeks, so that the leeks gathered by the gathering plates 21 can better enter the conveying channel 35. After being harvested, the leeks enter between the two front belt rollers 31. The front belt rollers 31 are wound with a conveyor belt 33, and the leeks move with the conveyor belt 33. The conveyor belt 33 is also wound around the rear belt roller 32, which is set horizontally, so that the conveyor belt 32 is twisted from vertical to horizontal to the ground, so that the originally vertical leeks become horizontal during the transmission process, which is convenient for the subsequent bundling, bundling and collection of the leeks.

[0045] like Fig. 9As shown, the bundling device 4 includes a first belt roller 41, a second belt roller 42 and a bundling conveyor belt 43. The first belt roller 41 is arranged at the discharge port of the conveying device 3, and the second belt roller 42 is arranged behind the first belt roller 41. The bundling conveyor belt 43 is wound around the first belt roller 41 and the second belt roller 42. A plurality of baffles 44 are arranged along the length direction of the bundling conveyor belt 43, and a storage space for accommodating leeks is formed between two adjacent baffles 44. A collection box 45 is arranged at the rear lower part of the second belt roller 42. A sixth driving member 46 is also arranged on the vehicle body 1, and the output end of the sixth driving member 46 is connected to the first belt roller 41. When the conveying device 3 conveys the leeks to the bundling device 4, the leeks fall onto the bundling conveyor belt 43. A plurality of baffles 44 are arranged on the bundling conveyor belt 3. The baffles 44 separate and bundle the leeks into multiple bundles for bundling by the bundling device 5. The sixth driving member 46 provides power for the rotation of the first belt roller 41, thereby driving the second belt roller 42 and the bundling conveyor belt 43 to work. A collecting box 45 is arranged at the rear lower part of the second belt roller 42, and the bundling conveyor belt 43 collects the bundled leeks and places them in the collecting box 45.
