[0038] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0039] The existing multifunctional leek harvester is usually complex in structure, which not only increases the manufacturing cost, but also makes operation and maintenance difficult. In order to solve this problem, the structure of the multifunctional leek harvester is required to reduce unnecessary components to improve the stability and reliability of the multifunctional leek harvester; the leek harvester in the prior art can only lay the harvested leek on the ground or pack it in bags, and the common form of selling leek on the market is to sell it in bundles, so it is often necessary to arrange manual labor to bundle the leek. Therefore, designing a function that can automatically bundle leek has also become another important goal of this application.

[0040] Based on the above technical problems, the purpose of this application is to provide a multifunctional leek harvester with compact structure, reasonable design, high structural strength and light weight, high harvesting efficiency and complete bundling. By adopting a specific technical solution, this application can effectively solve the above problems and provide users with a better user experience. Specifically, this application optimizes the structural design of the main body of the fuselage to make the main body more compact, thereby reducing the volume of the whole machine. At the same time, by simplifying the structure of the leek harvester and reducing unnecessary components, the stability and reliability of the multifunctional leek harvester are improved.

[0041] The present application embodiment provides a multifunctional leek harvester, referring to Figures 1 to 5 ,include:

[0042] A walking part, and a harvesting part, a conveying and arranging part, and an automatic bundling part arranged on the walking part, wherein:

[0043] The supporting and harvesting part is arranged at the front end of the walking part, and the supporting and harvesting part includes a clamping conveyor belt 201, a shearing device 202, a supporting head 203, a tool lifting platform 204, and a first roller 205. The supporting head 203 is located at the front end of the supporting and harvesting part, and the supporting head 203 includes two gathering plates. The clamping conveyor belt 201 is located behind the supporting head 203. The clamping conveyor belt 201 is provided with at least one pair, and the two clamping conveyor belts 201 in each pair gradually move closer from front to back. The clamping conveyor belt 201 is sleeved on the first roller 205, and the openings at the front ends of the two clamping conveyor belts 201 correspond to the openings of the two gathering plates. The shearing device 202 is arranged below the clamping conveyor belt 201, and the shearing device 202 is arranged on the tool lifting platform 204. The screw of the first screw motor is connected to the tool lifting platform 204, and the screw of the first screw motor is arranged vertically;

[0044] The conveying and aligning part includes a twisting conveyor belt 302 and an aligning conveyor belt 303. The twisting conveyor belt 302 is arranged behind the clamping conveyor belt 201. There is at least one pair of twisting conveyor belts 302. The front ends of the two twisting conveyor belts 302 in each pair are sleeved on the first roller 205, and the rear ends of the twisting conveyor belts 302 are sleeved on the second roller arranged at the rear. The second roller is arranged perpendicular to the first roller 205. The aligning conveyor belt 303 is arranged behind the twisting conveyor belt 302.

[0045] The automatic bundling part includes a box body 405, a robotic gripper 404, a second screw motor 403, a crank rocker mechanism 401, a bundling rocker arm 402, and a stepper motor 406. The box body 405 is arranged behind the entire conveyor belt 303, and a box door is provided at the lower end of the box body 405. The robotic gripper 404 is arranged below the box door. The screw of the second screw motor 403 is connected to the robotic gripper 404, and the screw of the second screw motor 403 is horizontally arranged and extends from front to back. The bundling rocker arm 402 is arranged behind the robotic gripper 404, the lower end of the crank rocker mechanism 401 is connected to the bundling rocker arm 402, and the upper end of the crank rocker mechanism 401 is connected to the output shaft of the stepper motor 406.

[0046] In some embodiments, the walking part includes a wheel 101, a DC motor 102, a bearing 103, and a frame 104. The wheel 101 is arranged on the frame 104 through the bearing 103, and the output shaft of the DC motor 102 is connected to the wheel 101 to drive the wheel 101 to rotate. The harvesting part, the conveying and arranging part, and the automatic bundling part are all arranged on the frame 104.

[0047] Specifically, the walking part is realized by controlling the DC motor 102 through the control system. When the multifunctional leek harvester moves forward, the control system controls the DC motor 102 to rotate at an appropriate speed, thereby driving the wheels 101 forward; when the multifunctional leek harvester turns, the control system controls the speed and direction of each wheel 101, so that one of the wheels 101 rotates faster while the other remains stationary or rotates slower, thereby generating a torque difference, so that the multifunctional leek harvester turns; when the multifunctional leek harvester stops, the control system can reduce or stop the rotation of the DC motor 102 by controlling the current or voltage of the DC motor 102, thereby stopping the wheels 101.

[0048] In some embodiments, the harvesting part further includes a distance sensor, which is disposed on one side of the shearing device 202 and is electrically connected to the screw motor.

[0049] In some embodiments, the shearing device 202 includes a rotating blade and a folding knife.

[0050] Specifically, the whole multifunctional leek harvester comes to the front of the whole row of leeks, and the gathering plates of the supporting head 203 in front of the multifunctional leek harvester move on both sides of the leeks, gather the messy leaves of the leeks to the middle in the vertical direction, and then reach the middle of the two clamping conveyor belts 201 through them, and two driving motors drive the first rollers 205 (there are at least four first rollers 205, and each clamping conveyor belt 201 is respectively set on the first rollers 205 one in front and one in the back) to rotate to make the two clamping conveyor belts 201 close together, thereby clamping the leeks. When harvesting the first batch of leeks, when it reaches a certain position, that is, when the root of the leek reaches the folding knife, the folding knife cooperates with the rotating blade that is rotating, so as to cut the root of the leek, and at the same time, the right-angle blade of the folding knife can prevent the leek from falling to one side; when harvesting the second batch of leeks, the first screw motor drives the tool table lifting platform to move upward to a preset height, for example, 0.5 cm upward, and then the stationary right-angle blade cooperates with the rotating blade to achieve the shearing of the leek. The distance sensor installed near the shearing device 202 feeds back the measured accurate distance to the ball screw motor, thereby realizing automatic adjustment of the blade height.

[0051] In some embodiments, a baffle 305 is provided on one side of the entire conveyor belt 303 , and an eccentric vibration motor 304 is provided on the baffle 305 .

[0052] Specifically, the harvested leeks arrive at the twisting conveyor belt 302 via the clamping conveyor belt 201, which can rotate the leeks 90° clockwise, that is, change from a vertical state to a horizontal state, wherein the end of the clamping conveyor belt 201 and the beginning of the twisting conveyor belt 302 are connected to the same first roller 205 to prevent the cut leeks from falling, and then fall into the column conveyor belt 303 with the baffle 305 through its end. During the transportation process, the eccentric vibration motor 304 on the baffle 305 at the bottom of the column conveyor belt works, and under the combined effect of the certain slope of the column conveyor belt 303 and the baffle 305, the cut leeks can be evenly spread in the column conveyor belt 303, and the roots are neatly stacked.

[0053] In some embodiments, the height of the entire row of conveyor belts 303 gradually decreases from front to back.

[0054] In some embodiments, sponges are provided on the clamping conveyor belt 201 and the twisting conveyor belt 302 .

[0055] Specifically, when implementing the technical solution of the present application, in order to ensure the integrity of the leek, two pairs of gathering plates are designed in front of the multifunctional leek harvester, which can gather and gather the messy leek leaves toward the middle.

[0056] In order to prevent the leeks from falling to one side, the shearing device 202 adopts a method of cooperating a rotating blade and a folding knife.

[0057] There are two key points to realize the whole row of leeks. The first is the twisting conveyor belt 302. The harvested leeks arrive in the twisting conveyor belt 302 through the clamping conveyor belt 201, which can make the leeks rotate 90° clockwise, that is, change from a vertical state to a horizontal state. The end of the clamping conveyor belt 201 and the beginning of the twisting conveyor belt 302 are connected to the same axis to prevent the cut leeks from falling. The second is that the whole row conveyor belt 303 is designed with a certain slope, and an eccentric vibration motor 304 is also installed at its lower end. Under the combined effect of the eccentric vibration motor 304 and the slope, the leeks slide down until the roots of all the leeks reach the baffle 305. At the same time, sponges are provided on the clamping conveyor belt 201 and the twisting conveyor belt 302, so that the leeks can move with the conveyor belt.

[0058] In some embodiments, the stepper motor 406 is disposed above the strapping rocker arm 402 .

[0059] In some embodiments, the bundling rocker arm 402 is an inverted U-shape, one end of the crank rocker mechanism 401 is connected to the upper end of the rear of the bundling rocker arm 402, the lower end of the rear of the bundling rocker arm 402 is rotatably connected to the profile frame of the automatic bundling part, and the rotating shaft is parallel to the output shaft of the stepper motor 406, and a first bundling film roller is provided at the rear of the bundling rocker arm 402, and a second bundling film roller is provided at the lower end of the front of the bundling rocker arm 402, and the rotating axes of the first bundling film roller and the second bundling film roller are both parallel to the output shaft of the stepper motor 406.

[0060] In some embodiments, the automatic strapping part further includes a pressure sensor, which is disposed below the box 405 .

[0061] In some embodiments, a cutting platform is provided below the bundling rocker arm 402, and a blade is provided on the cutting platform.

[0062] Specifically, the leeks transported to the rear end of the entire conveyor belt 303 fall into the box 405, and the weight of the leeks acts on the pressure sensor. When the pressure value is detected to reach a certain weight, the pressure signal is converted into an electrical signal and sent to the motor controller, which issues a command to open the door of the box 405, and the leeks fall into the mechanical claw 404. The second screw motor 403 at the bottom drives the mechanical claw 404 to move toward the tail of the multifunctional leek harvester. When it moves to a certain position, the stepper motor 406 drives the crank rocker mechanism 401 to move, thereby driving the bundling rocker arm 402 connected to the rocker to move downward, so that the bundling film surrounds the cut leeks, and at the same time, the blade below pops out to cut the transparent tape.

[0063] Specifically, in order to realize the quantitative automatic bundling of leeks, a box 405 is designed. The leeks transported to the end of the whole conveyor belt 303 fall into the box 405, and the weight of the leeks acts on the pressure sensor. When the pressure value reaches a certain weight, the box door at the bottom of the box 405 opens, and the leeks fall into the mechanical claw 404, and then the mechanical claw 404 moves toward the bundling rocker arm 402 driven by the second screw motor. When it reaches a certain position, the film on the bundling rocker arm 402 is pressed down by the crank rocker mechanism 401, so that the bundling film completely wraps the leeks, and the top of the bundling rocker arm 402 reaches the cutting table, and the blade in the cutting table pops out to cut the bundling film to complete the bundling, and the bundling rocker arm 402 is reset. At this time, the bundled leeks in the mechanical claw 404 can be taken out, and then the mechanical claw 404 is reset for the next cycle.

[0064] In order to ensure the lightness and flexibility during bundling, the printing material of the bundling rocker arm 402 is ABS, which has high impact resistance.

[0065] In summary, compared with the existing technology, the present design has a compact structure and can realize the harvesting, sorting and bundling of leeks, etc., which reduces labor intensity, saves manpower and material resources, and is suitable for medium-sized and large-scale greenhouses or outdoor use.

[0066] 1 Use the torsion belt to adjust the spatial position of the leek from a vertical state to a horizontal state. At the same time, use the vibration motor and the slope partition belt transmission to align the leeks in different postures, laying a good foundation for the subsequent automatic bundling of the leeks.

[0067] 2. The quantitative automatic bundling of leeks is realized by cooperating with the pressure sensor, the bundling rocker arm of the crank rocker mechanism and the movable mechanical claw.

[0068] 3. The ball screw lifting tool table controls the shear blade to achieve a certain supporting function while cutting to prevent the leek from falling over, and at the same time realize the harvesting of leek at different heights multiple times.

[0069] 4. The functions of cutting, arranging and bundling leeks are integrated.

[0070] In general, the design of this multifunctional leek harvester can bring a more efficient, more convenient and more economical harvesting experience, which is a good choice for individual users and small businesses. The application of its key technical solutions makes this application have significant technical advantages and market prospects.
