Description

Technical Field

[0001] This invention relates to the field of agricultural machinery technology, and more specifically, to a leek bundling device and a harvesting vehicle. Background Technology

[0002] Chives, a type of leafy vegetable, belong to the genus Allium in the family Liliaceae. Native to China, they are a perennial leafy vegetable that can be harvested multiple times a year. Currently, most chive planting machines are overly bulky, lack sufficient automation, and have fragmented functions. Furthermore, most chive baling and packaging machinery is semi-automatic, with immature technology that cannot perfectly integrate with existing harvesting machinery. These machines frequently experience problems such as weak knots and low success rates; therefore, chive baling still primarily relies on manual labor.

[0003] A Chinese invention, publication number CN117546677A, discloses a highly automated leek harvester, including a head assembly and a vehicle body. The head assembly is mounted at the front of the vehicle body, which sequentially houses a driver's cab, a belt turning conveyor, a weighing device, a transfer device, and a loading device. The driver's cab contains a control system that controls various operations of the leek harvester. The belt turning conveyor transports the leeks harvested by the head assembly to the leek harvesting frame on the weighing device. The weighing device weighs the leeks and transmits the data to the control system. The transfer device then transfers the leek harvesting frame to the loading device, which temporarily stores the framed leeks. This leek harvester integrates continuous harvesting, sorting, framing, and transport, effectively solving the problem of existing technologies that cannot process harvested leeks and require manual framing and transport to the field ridges, thus greatly improving the harvesting efficiency of the leek harvester.

[0004] However, for easy sale, harvested chives still need to be bundled and packaged. In the above-mentioned technical solution, the harvested chives still need to be bundled and packaged manually, which increases the labor load and fails to automate the harvesting and bundling process. Moreover, manual bundling is not fast and cannot be adapted to the application scenario of efficient mechanical harvesting of chives. Summary of the Invention

[0005] To address the problem of low harvesting efficiency caused by the need for manual bundling of chives after harvesting, this invention provides a chive bundling device and harvesting vehicle that can bundle and package chives simultaneously during harvesting, achieving integrated and automated harvesting and packaging of chives. This eliminates the need for additional manual bundling, reducing the labor load and improving the efficiency of harvesting and bundling.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: a chive bundling device, comprising a bundling platform for placing and bundling chives, a paper tape conveying device for conveying the paper tape for bundling chives, a guide structure for guiding the movement of the paper tape to wrap around the chives, and a conjugate cam mechanism for supporting, cutting, and welding the paper tape. The guide structure is installed on the bundling platform, and the inner side of the guide structure has a guide groove. The conjugate cam mechanism is located below the bundling platform. The conjugate cam mechanism includes a first rotating shaft and a first driving component for driving the first rotating shaft to rotate.

The lower ends of the top support, the cutting component, and the welding component are slidably connected to the outer peripheral surfaces of the first cam, the second cam, and the third cam, respectively.

[0007] In this technical solution, the bundling device is used to bundle harvested chives. When the chives are conveyed to the bundling table, a paper tape conveyor conveys the paper tape for bundling to the bundling table. Under the guidance of the guide structure, the paper tape wraps around the chives on the bundling table. A conjugate cam mechanism is installed below the bundling table and rotates. The conjugate cam mechanism is equipped with a first drive component. The first drive component drives a first rotating shaft to rotate a first cam, a second cam, and a third cam. The rotating first cam, second cam, and third cam sequentially lift the top support, the cutting component, and the welding component to contact the paper tape on the bundling table, realizing the functions of supporting, cutting, and welding the paper tape. After cutting, the paper tape is welded together, so that the paper tape can firmly bind the chives and prevent them from scattering. Then the chives are removed from the bundling table, and the bundling device continues to bundle the next bunch of chives.

[0012] In this technical solution, a leek harvester is used to harvest leeks. The vehicle is positioned directly over the leeks planted in the field. The vehicle itself is powered, driving the leek harvesting device forward. A gathering and harvesting device is located at the front of the vehicle. As the vehicle moves forward, the leeks enter the gathering and harvesting device, where they are gathered and harvested.

Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting the present patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0032] The technical solution of the present invention will be 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 chive bundling device includes a bundling table 51 for placing and bundling chives, a paper tape conveying device 52 for conveying the paper tape used for bundling chives, a guide structure 55 for guiding the paper tape to wrap around the chives, and a conjugate cam mechanism 54 for supporting, cutting, and welding the paper tape. The guide structure 55 is mounted on the bundling table 51, and its inner side has a guide groove 551. The conjugate cam mechanism 54 is located below the bundling table 51 and includes a first rotating shaft 541 and a mechanism for driving the first rotating shaft 541 to rotate. The first drive assembly 548 has a first cam 542, a second cam 543, and a third cam 544 sequentially mounted on the first rotating shaft 541. A top support 545, a cutting component 546, and a welding component 547 are slidably connected vertically to the binding table 51, corresponding to the positions of the first cam 542, second cam 543, and third cam 544, respectively. The lower ends of the top support 545, cutting component 546, and welding component 547 are slidably connected to the outer peripheral surfaces of the first cam 542, second cam 543, and third cam 544, respectively. The binding device is used to bind harvested chives. When the chives are conveyed to the bundling table 51, the paper tape conveying device 52 conveys the paper tape for bundling to the bundling table 51. The paper tape moves along the guide groove 551 on the guide structure 55, eventually circling the chives on the bundling table 51. A conjugate cam mechanism 54 is installed below the bundling table 51 and rotates. The conjugate cam mechanism 54 is equipped with a first drive component. The first drive component drives the first rotating shaft 541 to rotate the first cam 542, the second cam 543, and the third cam 544. During rotation, the first cam 542, the second cam 543, and the third cam 544 sequentially lift the top support 545, the cutting component 546, and the welding component 547 to contact the paper tape on the bundling table 51, realizing the functions of supporting, cutting, and welding the paper tape. After cutting, the paper tape is welded together, so that the paper tape can firmly bind the chives and prevent them from falling apart. Then the chives are removed from the bundling table 51, and the bundling device continues to bundle the next bunch of chives.

[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, and the opening of the guiding structure 55 faces the bundling table 51. The second driving component 53 is connected to the guiding structure 55 to drive the guiding structure 55 to approach or move 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 that goes around the leeks once. 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, guiding the paper tape to move along the inner side of the "square" structure. 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, and the second driving component 53 can drive the guiding structure 55 to move in the direction away from or close 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 through the gap. When the guiding structure 55 approaches the bundling table 51 until it contacts the bundling table 51, the guiding structure 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 drive assembly 53 includes a lifting rack 531, a first reciprocating gear 532, a second reciprocating gear 533, a rocker arm 534, a first stop lever 535, and a second stop lever 536 connected to the guide structure 55. The lifting rack 531 meshes with the first reciprocating gear 532, and the first reciprocating gear 532 meshes with the second reciprocating gear 533. One end of the rocker arm 534 is rotatably mounted between the first reciprocating gear 532 and the second reciprocating gear 533 and is connected to the first drive assembly 548 for transmission. The first stop lever 535 is fixed on the side of the first reciprocating gear 532 facing the rocker arm 534, and the second stop lever 536 is fixed on the side of the second reciprocating gear 533 facing the rocker arm 534. The other end of the rocker arm 534 is provided with a protrusion 537 protruding in the direction of the first reciprocating gear 532 and the second reciprocating gear 533 for rotating the first stop lever 535 and the second stop lever 536. When the second drive assembly 53 is working, the rocker arm 534 rotates, and the protrusion 537 on the rocker arm 534 first contacts the first stop lever 535, causing the first stop lever 535 and the rocker arm 534 to rotate clockwise together, thereby driving the first reciprocating gear 532 to rotate clockwise, which in turn drives the lifting rack 531 to move the guide structure 55 upward. When the rocker arm 534 rotates to a certain position, the protrusion 537 of the rocker arm 534 disengages from the first stop lever 535 and then contacts the second stop lever 536, causing the second stop lever 536 to rotate clockwise, which in turn drives the second reciprocating gear 533 to rotate clockwise. The second reciprocating gear 533 meshes 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 drive assembly 548 also includes a drive wheel 5481 mounted on the first rotating shaft 541. The rotating end of the rocker arm 534 is provided with a transmission gear 538 and a transmission component 549. The transmission component 549 includes a full gear 5491 and a half gear 5492, which are coaxially connected. The full gear 5491 is connected to the first drive assembly 548 via transmission, and the half gear 5492 meshes with the transmission gear 538. Considering the need to minimize the drive source while ensuring precise engagement between the conjugate cam mechanism 54 and the guide structure 55, the second drive assembly 53 does not have a power source. The power for the second drive assembly 53 is provided by the first drive assembly 548, which drives the conjugate cam mechanism 54. Power is transmitted between the first drive assembly 548 and the second drive assembly 53 via the transmission component 549. The transmission component 549 includes a coaxial half gear 5492 and a full gear 5491. The rotating end of the rocker arm 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 drive wheel 5481. The full gear 5492 is connected to the drive wheel 5481, thereby realizing that the second drive component 53 works half a cycle after one rotation of the first rotating shaft 541.

[0038] Example 2

[0039] like Figure 5 As shown, a leek harvesting vehicle includes the leek bundling device 5 described in 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 mounted on the vehicle body 1. The gathering and harvesting device 2 is mounted at the front end of the vehicle body 1. The two ends of the conveying device 3 are aligned with the discharge port of the gathering and harvesting device 2 and the inlet of the bundling device 4, respectively. The bundling device 5 is mounted on one side of the bundling device 4. When harvesting leeks, the vehicle body 1 is aligned with the leeks planted in the ground. The vehicle body 1 itself is powered, which can drive the leek harvesting device forward. The gathering and harvesting device 2 is located at the front end of the vehicle body 1. As the vehicle body 1 moves forward, the leeks enter the gathering and harvesting device 2 and are gathered and harvested by it. 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 transports the harvested chives to the bundling device 4. The bundling device 4 bundles the harvested chives into multiple bundles. A binding device 5 is installed next to the bundling device 4. When the chives are transported to the binding device 5, they will be bundled together by the bundling device 4, thus achieving the initial packaging of the harvested chives.

[0040] like Figure 5As shown, the gathering and harvesting device 2 includes two gathering plates 21 arranged opposite 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 V-shape, forming a harvesting channel 23 between them. 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 outward V-shaped arrangement of the gathering plates 21 gives the gathering and harvesting device 2 a larger entrance, enabling it to gather and harvest a larger area of ​​chives. After the chives are gathered by the gathering plates 21, as the vehicle body 1 moves forward, the chives enter the harvesting device 22 below the gathering plates 21, where they are cut and output from the rear of the harvesting channel 23 into the conveying device 3. The two gathering plates 21 are tilted downwards and forwards of the vehicle body 1. Since the roots of chives planted in the ground are relatively concentrated near the ground, while the leaves at the upper part are more dispersed, the leaves of different bunches of chives are intertwined and difficult to separate. Therefore, the work should be carried out on the roots near the ground when gathering them. Thus, the two gathering plates 21 are tilted downwards and forwards of the vehicle body 1 to align with the roots of the chives to be harvested and gather them together.

[0041] like Figure 6 As shown, the harvesting device 22 includes a base plate 221, which is mounted on the front end of the vehicle body 1 and located below and behind the gathering plate 21. A first cutter 222 is fixed to the front end of the base plate 221, and a second cutter 223 is slidably connected to the base plate 221. A rocker mechanism 224 and a third drive member 225 are also provided on the base plate 221. The third drive member 225 is fixed to the base plate 221, one end of the rocker mechanism 224 is connected to the third drive member 225, and the other end of the rocker mechanism 224 is connected to the second cutter 223. The first cutter 222 and the second cutter 223 form a scissor-like structure, wherein the first cutter 222 is fixed, and the second cutter 223 moves relative to the first cutter 222 to cut the chives that enter between the first cutter 222 and the second cutter 223. The third driving component 225 provides power to the rocker mechanism 224, which drives the second cutter 223 to reciprocate. A lifting device is also provided on the base plate 221. The lifting device includes a rack 226 and a fourth driving component 227. The rack 226 is vertically fixed to the base plate 221, and the fourth driving component 227 is fixed to the vehicle body 1. A gear 228 is provided on the fourth driving component 227, and the gear 228 meshes with the rack 226. The lifting device can raise and lower the base plate 221 to different heights to adapt to different terrains or adjust the height for harvesting chives. The lifting device includes a rack 226 and a fourth driving component 227. The fourth driving component 227 is provided with a gear 228 that meshes with the rack 226. The fourth driving component 227 can drive the rack 226 up and down via the gear 228, thereby adjusting the height of the base plate 221.

[0042] like Figure 7As shown, a reel 211 is rotatably mounted on the gathering plate 21. A first driven gear is fixedly mounted on the reel 211, and a driving gear is connected to the drive shaft of the conveying device 3. The first driven gear meshes with the driving gear. The reel 211 can more quickly pull the chives into the gathering and harvesting device 2. Simultaneously, the reel 211 can change the direction of movement of the chives by moving them, allowing them to smoothly enter the conveying device 3. The reel 211 is connected to the driving gear on the conveying device 3 via the first driven gear, and the conveying device 3 provides the power source for the rotation of the reel 211.

[0043] Example 3

[0044] This embodiment is similar to Embodiment 2 above, except that, as 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. There are two front belt rollers 31, which are vertically arranged on both sides of the discharge port of the gathering and harvesting device 2. The rear belt roller 32 is arranged horizontally, and the two rear belt rollers 32 correspond one-to-one with the two front belt rollers 31. The two conveyor belts 33 are sequentially wound around the corresponding front belt rollers 31 and rear belt rollers 32. A conveying channel 35 for conveying chives 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 move the chives along the conveying channel 35 and change the chives from a vertical state to a horizontal state. The fifth driving component 34 provides power for the rotation of the front belt rollers 31. Two front belt rollers 31 are provided, vertically positioned on either side of the discharge port of the gathering and collecting device 2. The front belt rollers 31 are perpendicular to the plane of the two gathering plates 21. After the chives are harvested, they move perpendicular to the plane of the two gathering plates 21 under the action of the reel 211 on the gathering plates 21. The perpendicularity of the front belt rollers 31 to the plane of the two gathering plates 21 ensures that the conveying channel 35 between the two front belt rollers 21 is also perpendicular to the plane of the two gathering plates 21, matching the movement of the chives and facilitating better entry of the chives gathered by the gathering plates 21 into the conveying channel 35. After harvesting, the chives enter between the two front belt rollers 31, with a conveyor belt 33 wound around the front belt rollers 31, allowing the chives to move along with the conveyor belt 33. The conveyor belt 33 is simultaneously wound around the rear roller 32, which is horizontally positioned so that the conveyor belt 32 is twisted from being perpendicular to the ground to being horizontal to the ground. This makes the chives, which were originally vertical, become horizontal during the conveying process, which is convenient for the subsequent bundling, tying and collection of the chives.

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