[0036] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] This embodiment provides a leek harvesting device, such as... Figures 1-8 As shown, the harvesting device includes a fixed cover 1, a walking mechanism 2 symmetrically arranged on both sides of the bottom of the fixed cover 1, a cutting mechanism 3 arranged between the two walking mechanisms 2 and located below the fixed cover 1, a conveying mechanism 4 arranged on one side of the output end of the cutting mechanism 3, a bundling mechanism 5 arranged on the conveying mechanism 4 for bundling the chives, a collection box 6 arranged on the side of the conveying mechanism 4 away from the cutting mechanism 3 for collecting the chives, and a driving mechanism 7 arranged on the fixed cover 1 for transporting the collection box 6; the harvesting device also includes a controller, a front camera fixed on the fixed cover 1 corresponding to the input end of the cutting mechanism 3 for identifying the chives, and a rear camera fixed on the fixed cover 1 corresponding to the position of the driving mechanism 7 for identifying the position of the collection box 6. The front camera and the rear camera are both connected to the input end of the controller, and the walking mechanism 2, the cutting mechanism 3, the conveying mechanism 4, the bundling mechanism 5 and the driving mechanism 7 are all connected to the output end of the controller.

[0038] In use, first, the front camera collects image information in front of the cutting mechanism 3 in real time, then the front camera transmits the collected image information to the controller, the controller analyzes and processes the image data, and identifies the location of the leeks, then according to the identification result, the walking mechanism 2 is started to move the device to the position of the leeks, when the device moves to the appropriate position, the controller sends a command to start the cutting mechanism 3, which uses the cutting mechanism 3 to gather and cut the leeks, the cut leeks will fall on the conveying mechanism 4, then the conveying mechanism 4 will convey the cut leeks to the baling mechanism 5 for baling, and then continue to convey the baled leeks to the storage box 6 for storage, however, when the storage box 6 is full, the rear camera can identify the unloading position, and the controller sends a command to start the walking mechanism 2 to move the device to the unloading position, then start the driving mechanism 7 to unload the full storage box 6 from the device, and take the empty storage box 6 to the device, so as to continue to use the device to cut leeks. The whole process reduces manual intervention, greatly improves the harvesting efficiency, and significantly reduces the labor cost.

[0039] Specifically, the walking mechanism 2 includes a fiberglass plate frame 21 fixedly arranged at both sides of the bottom of the fixed cover 1, a connecting shaft 22 symmetrically and rotatably connected at both ends of the fiberglass plate frame 21, a moving wheel 23 fixedly connected to the two connecting shafts 22 and located inside the fiberglass plate frame 21, a transmission sprocket 24 fixedly sleeved on the two connecting shafts 22, a transmission chain 25 arranged on the two transmission sprockets 24, a first motor 27 fixedly installed inside the fiberglass plate frame 21, a second bevel gear 28 fixedly installed on the output shaft of the first motor 27, and a first bevel gear 26 fixedly sleeved on one of the connecting shafts 22 and engaged with the second bevel gear 28, the two transmission sprockets 24 are connected and transmit power through the transmission chain 25, and the first motor 27 is connected to the output end of the controller;

[0040] The controller sends a start command to the first motor 27 on the walking mechanism 2 at both sides below the fixed cover according to the image information collected by the front camera, at this time, the first motor 27 drives the second bevel gear 28 connected thereto to rotate, since the second bevel gear 28 is engaged with the first bevel gear 26 on one of the connecting shafts 22, therefore, with the rotation of the second bevel gear 28, one of the connecting shafts 22 also rotates synchronously, since the two connecting shafts 22 are both installed with the transmission sprockets 24, and the two transmission sprockets 24 are connected and transmit power through the transmission chain 25, therefore, when one of the connecting shafts 22 rotates, the other connecting shaft 22 also rotates synchronously, so that the moving wheels 23 on the two connecting shafts 22 can rotate forward or backward synchronously, providing power for the device to move forward or backward, so that the device can flexibly move to the position of the leeks and the unloading position on the ground.

[0041] Further, the cutting mechanism 3 comprises a fixed frame 31 fixedly arranged on the fixed cover 1 between the two glass fiber plate frames 21 and located at the side of the input end of the conveying mechanism 4, a shunt assembly 32 symmetrically arranged on the fixed frame 31, a third motor 33 fixedly installed on the bottom of the fixed frame 31 and located at the end of the two shunt assemblies 32 away from the conveying mechanism 4, a drive gear 34 fixedly connected to the output shaft of the third motor 33, a transmission gear 35 rotatably connected to the fixed frame 31 on the two sides of the drive gear 34 and corresponding to the two shunt assemblies 32, and a blade 36 arranged on the bottom of the fixed frame 31 away from the conveying mechanism 4 and fixedly connected to the two transmission gears 35, respectively. The third motor 33 and the shunt assembly 32 are connected to the output end of the controller, and the two transmission gears 35 are engaged with the two sides of the drive gear 34, respectively. The cutting mechanism 3 further comprises a rotating shaft 37 rotatably connected to the fixed frame 31 at the side close to the conveying mechanism 4 and corresponding to the shunt assembly 32, a rudder door 38 fixedly connected to the rotating shaft 37 and arranged in a ring shape for blocking the leeks at the shunt assembly 32, a pressure sensor fixedly installed on the rudder door 38 for detecting the pressure of the blocked leeks, and a fourth motor 39 fixedly installed on the fixed frame 31 for driving the rotating shaft 37 to rotate. The pressure sensor is connected to the input end of the controller, and the fourth motor 39 is connected to the output end of the controller.

[0042] When the controller identifies the position of the leeks according to the front camera and starts the walking mechanism 2 to move forward and sequentially reach the positions of the leeks in the field, the controller will send a command to start the third motor 33 and the shunt assembly 32 at the same time. At this time, the shunt assembly 32 will move forward with the walking mechanism 2 and sequentially gather the leeks growing in the forward direction, while the third motor 33 will drive the driving gear 34 to rotate. Since the driving gear 34 is meshed with two transmission gears 35 on both sides, when the driving gear 34 rotates, the two transmission gears 35 will drive the connected blades 36 to rotate, respectively. Since the two blades 36 are correspondingly arranged with the two shunt assemblies 32, when the shunt assembly 32 moves forward with the walking mechanism 2 and gathers the leeks, the rotating blades 36 will cut into the roots of the leeks to complete the cutting action. The cut leeks will be conveyed backward to the ring-shaped rudder doors 38 under the action of the shunt assembly 32 and will be blocked by one of the rudder doors 38. As the rudder door 38 blocks, the leeks will accumulate continuously. Then, the pressure acting on the rudder door 38 gradually increases, and the pressure sensor installed on the rudder door 38 will monitor the pressure change in real time. When the pressure reaches the preset threshold, the pressure sensor will convert the pressure signal into an electrical signal and transmit it to the controller. After receiving the signal, the controller will send a start command to the fourth motor 39, so that the fourth motor 39 drives the rotating shaft 37 to rotate and in turn drives the rudder door 38 that blocks the leeks to open, so that the accumulated leeks can fall on the conveying mechanism 4 for transmission. At the same time, after the rudder door 38 that blocks the accumulated leeks is opened by the rotation of the rotating shaft 37, the next adjacent rudder door 38 arranged in a ring shape on the rotating shaft 37 will rotate to the shunt assembly 32 to block the subsequent cut leeks. In this way, stable cutting and blocking of the leeks can be realized.

[0043] In order to convey the cut leeks to the rudder door 38, the shunt assembly 32 comprises two first connecting rods 321 and two second connecting rods 322 symmetrically arranged on the fixed frame 31, first synchronous pulleys 323 and second synchronous pulleys 324 linearly distributed and fixedly sleeved on the two first connecting rods 321 and the two second connecting rods 322 respectively, the first synchronous pulleys 323 corresponding arranged on the two second connecting rods 322 are connected and power is transmitted through the first synchronous belt 325, the second synchronous pulleys 324 corresponding arranged on the two first connecting rods 323 are connected and power is transmitted through the second synchronous belt 326, the top ends of the two first connecting rods 321 and the second connecting rods 322 located at the same end are fixedly installed with connecting gears 327, the two connecting gears 327 are engaged, the fixed frame 31 is fixedly installed with a second motor 328 for driving one of the first connecting rods 321 to rotate, the second motor 328 is connected with the output end of the controller, the side of the fixed frame 31 corresponding to the blade 36 is provided with three shunt plates 329 corresponding to the two shunt assemblies 32 for gathering the leeks into the first synchronous belt 325 and the second synchronous belt 326, and the side of the fixed frame 31 corresponding to the rudder door 38 is fixedly provided with a baffle for blocking the cut leeks to make the leeks pour into the strip-shaped hollow collecting groove 45;

[0044] When the controller starts the walking mechanism 2 to make the whole device move in the field and pass through the position of the leeks in turn, the three shunt plates 329 arranged will first separate the leeks in the field, so that the leeks are gathered to the corresponding blades 36 through the two channels separated by the shunt plates 329. At the same time, the controller will send a command to start the second motor 328 on the two shunt components 32, and the second motor 328 will drive the first connecting rod 321 connected thereto to rotate. Since the first connecting rod 321 and the second connecting rod 322 on each shunt component 32 are connected and engaged through the connecting gear 327, when one of the first connecting rods 321 on each shunt component 32 rotates, the second connecting rod 322 arranged correspondingly will also rotate synchronously. Since the two first connecting rods 321 on each shunt component 32 are connected with the first synchronous pulley 323, the two first synchronous pulleys 323 are connected and transmit power through the first synchronous belt 325, so the first synchronous belt 325 can rotate synchronously with one of the first connecting rods 321. Similarly, when one of the second connecting rods 322 on each shunt component 32 rotates, the two second connecting rods 322 are connected with the second synchronous pulley 324, and the two second synchronous pulleys 324 are connected and transmit power through the second synchronous belt 326, so the second synchronous belt 326 can rotate synchronously with one of the second connecting rods 322. Therefore, the first synchronous pulley 323 and the second synchronous pulley 324 on each shunt component 32 can rotate synchronously, and the leeks preliminarily gathered through the front shunt plate 329 will be further gathered under the action of the friction force of the first synchronous pulley 323 and the second synchronous pulley 324. When the rotating blade 36 contacts the gathered leeks, it can cut into the root of the leeks to complete the cutting of the leeks, and the cut leeks will also be continuously conveyed to the rudder door 38 under the synchronous rotation of the first synchronous pulley 323 and the second synchronous pulley 324.

[0045] Further, the conveying mechanism 4 comprises a first conveying belt 41 arranged on the fixed cover 1 corresponding to the side of the rudder door 38 away from the flow distribution assembly 32, a rectangular frame 42 symmetrically arranged at both ends of the first conveying belt 41, a connecting sprocket 43 rotatably connected at the corners of the rectangular frame 42 respectively, an endless chain 44 arranged on the four connecting sprockets 43, and a fifth motor 49 fixedly installed on the rectangular frame 42 for driving one of the connecting sprockets 43 to rotate, the four connecting sprockets 43 on the same rectangular frame 42 are connected and transmit power through the corresponding arrangement of the endless chain 44, the endless chain 44 between the two rectangular frames 42 is rotatably connected with a strip-shaped hollow collecting groove 45 arranged in a ring shape for receiving the leeks at the rudder door 38, a fork-shaped frame 46 is fixedly arranged on one side of the first conveying belt 41 for penetrating from the strip-shaped hollow collecting groove 45, and a second conveying belt 47 is arranged at the end of the first conveying belt 41 away from the rudder door 38 and connected with the fixed cover 1;

[0046] When the fifth motor 49 on each rectangular frame 42 is started, it will drive the rotation of the connecting sprocket 43 connected thereto, when one of the connecting sprockets 43 on each rectangular frame 42 rotates with the driving of the fifth motor 49, the endless chain 44 will rotate synchronously, at this time, the strip-shaped hollow collecting groove 45 arranged in a ring shape between the two endless chains 44 will also move in a cycle, when the rudder door 38 is opened, the cut leeks will automatically fall into the strip-shaped hollow collecting groove 45 which moves in a cycle, at the same time, with the continuous operation of the endless chain 44, the strip-shaped hollow collecting groove 45 containing the leeks will move to the position of the fork-shaped frame 46 in sequence, when the strip-shaped hollow collecting groove 45 passes through the fork-shaped frame 46, the fork-shaped frame 46 will insert the leeks in the strip-shaped hollow collecting groove 45, so that the leeks fall on the first conveying belt 41, then the first conveying belt 41 will convey the leeks falling thereon to the side of the bundling mechanism 5, so as to be bundled by the bundling mechanism 5, and the bundled leeks will continue to be transported by the first conveying belt 41 and transferred to the second conveying belt 47 connected with the fixed cover 1, finally the second conveying belt 47 will convey the bundled leeks to the storage box 6, completing the whole conveying process.

[0047] In addition, in order not to affect the loading and unloading of the storage box 6, the fixed cover 1 is provided with a turnover assembly 48 for turning over the two second conveying belts 47 at the position corresponding to the upper position of the storage box 6, the turnover assembly 48 comprises a mounting frame 481 fixedly installed on the fixed cover 1 and located between the two second conveying belts 47, a servo cylinder 482 fixedly installed on the mounting frame 481 and connected with the output end of the controller, two movable frames 483 provided at the bottom end of the piston rod of the servo cylinder 482, and a turnover shaft 484 symmetrically and fixedly connected to the mounting frame 481, the two ends of the movable frame 483 are respectively rotatably connected with the piston rod of the servo cylinder 482 and the side edge of the second conveying belt 47, and the side of the second conveying belt 47 away from the movable frame 483 is rotatably connected to the turnover shaft 484;

[0048] When the controller sends a command to start the driving mechanism 7 to take out the empty storage box 6 or place the full storage box 6, it will simultaneously start the servo cylinder 482, when the piston rod of the servo cylinder 482 extends, since one end of the two movable frames 483 is rotatably connected with the bottom end of the piston rod of the servo cylinder 482, and the other end is respectively rotatably connected with the side edges of the two second conveying belts 47, therefore the extension movement of the piston rod will push the two movable frames 483 to move downward and drive the two second conveying belts 47 to turn over around the corresponding turnover shaft 484, so that the two second conveying belts 47 are turned over to the outside to be inclined, so as to avoid the loading and unloading space of the storage box 6, and prevent the obstruction, when the piston rod of the servo cylinder 482 retracts, it will pull the two movable frames 483 to move upward, with the upward movement of the two movable frames 483, the two second conveying belts 47 will turn over inward around the turnover shaft 484 to be horizontal, so as to facilitate the subsequent conveying work of the bundled leeks.

[0050] In the initial state, the baling belt is sleeved on the mounting plate 51, and the end of the baling belt is threaded between the two friction wheels 53. According to the conveying of the leeks by the conveying mechanism 4, the controller sends a command to the sixth motor 54 to start the sixth motor 54 to drive one of the friction wheels 53 to rotate, and the other friction wheel 53 is driven to rotate passively. The two friction wheels 53 are in contact with the baling belt placed on the sleeve 52, and the baling belt is pulled out of the sleeve 52 by friction. Then, the guide groove 55 guides the baling belt to ensure that it is accurately conveyed along the set path to the guide frame 56, and prepares for baling around the leeks. With the continuous rotation of the two friction wheels 53, the tail end of the baling belt will reach between the abutting block 571 and the pressure roller 572 under the guidance of the guide frame 56. Therefore, when the first conveying belt 41 conveys the leeks to the position of the guide frame 56, the baling belt can be wrapped around the leeks. At the same time, the controller sends a command to start the seventh motor 582 to drive the rotating wheel 581 to rotate. With the rotation of the rotating wheel 581, the eccentric shaft 583 on the rotating wheel 581 drives the first connecting rod 573 to rotate reciprocally. At this time, the first connecting rod 573 synchronously drives the pressure roller 572 to move close to the abutting block 571, and presses the tail end of the baling belt between the abutting block 571 and the pressure roller 572. At the same time, the eccentric shaft 583 also drives the cutting block 584 to move reciprocally through the connection of the second connecting rod 585. When the cutting block 584 moves close to the guide groove 55, it cuts the baling belt located at the position of the guide groove 55, so that the baling belt around the leeks forms an independent baling unit. After the baling belt is cut, the controller sends a command to start the eighth motor 595 to drive the fourth bevel gear 594 to rotate. Since the fourth bevel gear 594 is in meshing with the third bevel gear 593, with the rotation of the fourth bevel gear 594, the third bevel gear 593 and the support shaft 592 also rotate synchronously. Then, the S-shaped frame 591 connected to the support shaft 592 hooks the two ends of the independent baling unit and winds and tightens the two ends, thereby completing the baling operation of the leeks.

[0051] It can be understood that the driving mechanism 7 includes two sliding frames 72 which move laterally on the fixed cover 1 and are located at the end of the second conveying belt 47 away from the guide frame 56, a second screw rod 75 which is rotatably connected to the fixed cover 1 and is screwed with the sliding frame 72, a tenth motor 76 which is fixedly installed on the fixed cover 1 and is used to drive the second screw rod 75 to rotate, a mounting seat which moves laterally on the fixed cover 1 and corresponds to the position above the sliding frame 72, a bracket 71 which moves longitudinally between the sliding frame 72 and the mounting seat, a first screw rod 73 which is rotatably connected between the sliding frame 72 and the mounting seat and is screwed with the bracket 71, and a ninth motor 74 which is fixedly installed on the mounting seat and is used to drive the first screw rod 73 to rotate. The tenth motor 76 and the ninth motor 74 are connected with the output end of the controller.

[0052] When the empty storage box 6 is needed, the position of the empty storage box 6 is judged through the capture and recognition of the rear camera, and the controller starts the walking mechanism 2 to move the whole device to the position of the empty storage box 6. After reaching the position, the tenth motor 76 is started to drive the second lead screw 75 to rotate, and the sliding frame 72 is moved forward. Since the first lead screw 73 is connected to the sliding frame 72 and the mounting seat, the first lead screw 73, the bracket 71 screwed with the first lead screw 73, the mounting seat, and the ninth motor 74 can be synchronously moved forward away from the second conveyor belt 47 and close to the empty storage box 6 with the movement of the sliding frame 72. Then, the ninth motor 74 is started to drive the first lead screw 73 to rotate, and the bracket 71 is lifted up, so that the empty storage box 6 can be lifted up. Then, the tenth motor 76 is started to drive the second lead screw 75 to rotate in the opposite direction, and the sliding frame 72 is moved backward. At this time, the first lead screw 73, the bracket 71 screwed with the first lead screw 73, the mounting seat, and the ninth motor 74 and the empty storage box 6 lifted by the bracket 71 are also synchronously moved backward to close to the second conveyor belt 47. Then, the ninth motor 74 is started to drive the first lead screw 73 to rotate in the opposite direction, and the bracket 71 drives the lifted storage box 6 to descend to a position below the second conveyor belt 47, so as to receive the leeks after being bundled. Conversely, when the full storage box 6 is needed to be unloaded, the ninth motor 74 is started to drive the first lead screw 73 to lift the bracket 71, and the full storage box 6 is lifted up. Then, the tenth motor 76 is started to drive the second lead screw 75 to move the sliding frame 72 forward, and the full storage box 6 lifted by the bracket 71 is synchronously moved forward to close to the unloading position with the movement of the sliding frame 72. Then, the ninth motor 74 is started to drive the first lead screw 73 to lower the bracket 71, so that the full storage box 6 is lowered to the unloading position. Then, the tenth motor 76 is started to drive the second lead screw 75 to move the sliding frame 72 backward, so as to move the bracket 71 away from the two sides of the full storage box 6, thereby completing the unloading of the storage box 6.

[0053] It should be noted that the leeks reaching the first conveyor belt 41, the fork-shaped frame 46, the second conveyor belt 47, and the storage box 6 are all monitored and positioned by corresponding sensors. Through the monitoring of the corresponding sensors, corresponding signals can be sent to the controller in real time, so that the controller sends corresponding instructions to start the conveying mechanism 4, the bundling mechanism 5, and the driving mechanism 7 to perform corresponding operations. The first conveyor belt 41 and the second conveyor belt 47 are both prior art, the controller is an stm32f103zet6 single-chip microcomputer, the pid algorithm is used to realize closed-loop control, serial communication is used to realize data transmission with vision and remote controller, and a self-drawn pcb main control board is used to realize convenient wiring.
