Description

Technical Field

[0001] This invention relates to the field of leek harvesting technology, specifically to an integrated machine for leek harvesting and leek yellow covering. Background Technology

[0002] Currently, in the agricultural sector, some auxiliary machinery has appeared on the market for harvesting chives, but these machines still require manual labor and are only semi-automated. Furthermore, using these machines causes significant damage to the chives, and the harvested chives are scattered and disorderly, causing difficulties for subsequent steps such as bundling. In addition, these machines are energy-intensive and polluting.

[0003] To address the above issues, Chinese utility model patent CN217936549U discloses a chive harvesting machine. Through the cooperation of a first motor, a rotating column, and blades, it facilitates the cutting of chive flower stems, thereby enabling the suction device, suction hopper, and telescopic hose to work together to transport the chive flowers into a collection device. However, this machine, which cuts chives above the root, uses a high-speed rotating saw blade for cutting. This not only causes significant damage to the chives but also, after a period of cutting, the blades develop adhesive wear similar to that experienced during shaving, leading to increased tearing and reduced chive yield.

[0004] Furthermore, there is currently no equipment on the market that automatically places shade cylinders for cultivating leek sprouts. The process of cutting leeks and placing shade cylinders to cultivate leek sprouts is continuous. Even after the leek harvesters have finished their work, manual labor is still required to repeatedly place the shade cylinders to cultivate the leek sprouts, thus not fully realizing unmanned leek cultivation. Therefore, to avoid the shortcomings of existing technology, it is necessary to improve it. Summary of the Invention

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] like Figures 1 to 6 The leek harvesting and leek yellow shading integrated machine of the present invention includes a frame 1, a control system 2, and a traveling mechanism, a clamping and cutting mechanism 3, a flexible transmission mechanism 4, and a sunshade tube placement mechanism 5, which are electrically connected to the control system 2. The traveling mechanism is installed at the bottom of the frame 1 and drives the frame 1 to travel. The clamping and cutting mechanism 3 is installed at the front end of the frame 1 in the traveling direction. The flexible transmission mechanism 4 is installed at the rear of the clamping and cutting mechanism 3. The sunshade tube placement mechanism 5 is installed at the rear end of the frame 1 in the traveling direction.

[0028] The traveling mechanism includes a first front wheel 6, a second front wheel 7, a first rear wheel 8, a second rear wheel 9, a first drive motor 10 driving the first rear wheel 8, a second drive motor driving the second rear wheel 9, a first transmission mechanism connecting the first rear wheel 8 and the first drive motor 10, and a second transmission mechanism connecting the second rear wheel 9 and the second drive motor. The first and second transmission mechanisms each include a first driving wheel 11 mounted on the output ends of the first and second drive motors, a first driven wheel mounted on the axles of the first and second rear wheels 8 and 9, and a first synchronous belt 12 connecting the first driving wheel 11 and the first driving wheel. The frame 1 uses an aluminum skeleton, and the platform on the frame 1 where the control system 2 is placed is made of acrylic sheet. The first front wheel 6 and the second front wheel 7 use solid rubber tires, which are simple driven wheels used for load-bearing and preventing the machine from getting stuck in potholes. The first rear wheel 8 and the second rear wheel 9 use hollow pneumatic tires to improve the machine's shock absorption capacity and reduce replacement costs. The traveling mechanism has two working modes. The first mode is that the first rear wheel 8 and the second rear wheel 9 rotate at the same speed, and the machine moves in a straight line at a constant speed. The second mode is that the first rear wheel 8 and the second rear wheel 9 operate at a certain speed difference, and make small-scale fine-tuning changes of direction while ensuring that the tire wear rate is small, so as to achieve steering movement.

[0029] The clamping and cutting mechanism 3 includes a clamping assembly, a cutting assembly, and driving mechanisms for driving the clamping assembly and the cutting assembly respectively. The clamping assembly includes a clamp housing 13, a clamp inner housing 14, a guide rod 15 passing through the clamp inner housing 13, a path rod 16 sliding horizontally on the clamp inner housing 13, and a clamping rod 17 hinged to the front end of the clamp inner housing 14. A first push-pull rod 18 is hinged to the upper part of the front end of the guide rod 15, and a first rack 19 is fixed to the lower part of the front end of the guide rod 15. The first push-pull rod 18 is hinged to the clamping rod 17. The cutting assembly includes a positioning groove fixed to the base plate of the clamp housing 13, and a drive mechanism mounted on a fixed... The second rack 20 is located in the slot, and a second push-pull rod 21 is fixedly installed at the front end of the second rack 20, along with a blade 22 hinged to the second push-pull rod 21. The drive mechanism includes a third drive motor 23, a rotating shaft 24 passing through the fixture housing 13 and the fixture inner housing 14 respectively, a gear 25 fixed to the rotating shaft 24, and a crank-rocker mechanism 26 connected to the output end of the third drive motor 23 and the rotating shaft 24. The first rack 19 and the second rack 20 mesh with the gear 25 respectively. The inner wall of the fixture inner housing 14 is provided with horizontal guide grooves 27, the outer wall of the fixture inner housing 13 is provided with cylindrical pins 28, and the outer wall of the fixture housing 13 is provided with arc-shaped guide grooves 29. The path rod 16 slides within the horizontal guide grooves 27, and the cylindrical pins 28 slide within the arc-shaped guide grooves 29. The clamping ends of the clamping rod 17 are respectively provided with slots 30 and positioning rods 31 that are adapted to the slots 30, which increases the closure of the clamping rod 17, improves the stability of clamping the chives, and reduces the damage to the chives during clamping; the blade 22 is provided with an arc-shaped blade shell 32 to reduce the damage to the chives during cutting. The arc-shaped blade shell 32 and the blade 22 are assembled separately, which makes it convenient to replace the blade 22.

[0030] The clamping and cutting mechanism 3 operates in two states. First, when the third drive motor 23 rotates forward, the guide rod 15 moves in the machine's direction of travel, the clamping assembly opens, and the second push-pull rod 21 moves in the opposite direction, opening the cutting assembly. Simultaneously, the inner clamp shell 14 tilts forward and downward, remaining in a standby state, during which time it cannot clamp or cut the chives. Second, when the third drive motor 23 rotates in the opposite direction, the guide rod 15 moves in the opposite direction, the clamping assembly closes, and the second push-pull rod 21 moves in the machine's direction, closing the cutting assembly. That is, the inner clamp shell 14 slides downward along the arc-shaped guide groove 29, causing the two clamping rods 17 to straighten the chives upward in the closed state. Simultaneously, the second push-pull rod 21 moves forward, causing the cutting assembly to close and cut the chives. Because the chives are stretched before being cut, the cuts are cleaner. Compared to the high-speed sawing of soft chives in existing technologies, this invention reduces damage to the chives.

[0031] When the clamping and cutting mechanism 3 starts working, the third drive motor 23 rotates unidirectionally at a certain speed. At the same time, the crank-rocker mechanism 26 connected to it converts the unidirectional uniform rotation of the third drive motor 23 into a variable-speed periodic oscillation of the rocker within a certain angle range, causing the rotating shaft 24, which is connected to the third drive motor 23, to also rotate in a variable-speed periodic manner. The gear 25 on the rotating shaft 24 meshes with the first rack 19 and the second rack 20 respectively, causing the guide rod 15 to move back and forth, driving the first push-pull rod 18 to move, thereby increasing or decreasing the angle of the clamping rod 17. At the same time, the second rack 20 moves back and forth in the positioning groove, and the second push-pull rod 21 connected to the second rack 20 drives the blade 22 to move, thereby increasing or decreasing the angle of the blade 22. When the rotating shaft 24 rotates, the path rod 16 moves along the horizontal guide groove 27, while the cylindrical pin 28 moves along the arc-shaped guide groove 29. Correspondingly, the inner housing 14 of the clamp makes a circular motion at a certain angle with the axis of the rotating shaft 24 as the center. At this time, due to the circular motion of the inner housing 14, the path rod 16 translates relative to the inner housing 14 along the arc-shaped guide groove 29 of the outer housing 13. Since the path rod 16 drives the guide rod 15 to move, it gives the guide rod 15 a forward force, which improves the smoothness of the movement of the clamping assembly. That is, the inner housing 14 of the clamp swings relative to the outer housing 13 along the arc-shaped guide groove 29. When the clamping rods 17 retract, the arc-shaped guide groove 29 plays a guiding role, so that the pair of clamping rods 17 can swing up and down to achieve the action of straightening the chives.

[0032] The flexible transmission mechanism 4 includes a first active front rubber wheel 33 and a second active front rubber wheel 34 mounted above the clamping and cutting mechanism 3, a first passive rear rubber wheel 35 and a second passive rear rubber wheel 36 mounted on the rear side of the frame 1, a first sponge layer track 37 connected to the first active front rubber wheel 33 and the first passive rear rubber wheel 35, a second sponge layer track 38 connected to the second active front rubber wheel 34 and the second passive rear rubber wheel 36, a fourth drive motor 39 that drives the first active front rubber wheel 33 and the second active front rubber wheel 34 to rotate, and a third transmission mechanism connected to the fourth drive motor 39 and the first active front rubber wheel 33 and the second active front rubber wheel 34. The rotating shafts of the first active front rubber wheel 33 and the second active front rubber wheel 34 are vertically arranged, and the rotating shafts of the first passive rear rubber wheel 35 and the second passive rear rubber wheel 36 are horizontally arranged. The third transmission mechanism includes a second driving wheel 40 mounted on the output end of the fourth drive motor 39, a second driven wheel 41 and a first transmission gear 42 mounted on the shaft of the first driving front rubber wheel 33, a second transmission gear 43 mounted on the shaft of the second driving front rubber wheel 34, and a second synchronous belt 44 connecting the second driving wheel 40 and the second driven wheel 41. The first transmission gear 42 and the second transmission gear 43 mesh with each other. Through the third transmission mechanism, the first driving front rubber wheel 33 and the second driving front rubber wheel 34 rotate at the same angular velocity. When the chives enter the first sponge layer track 37 and the second sponge layer track 38, the chives are clamped between the first sponge layer track 37 and the second sponge layer track 38, giving the chives a tension force so that the chives are always placed between the first sponge layer track 37 and the second sponge layer track 38 during the transmission process. The first sponge layer track 37 and the second sponge layer track 38 transport the chives from a vertical direction to a horizontal direction to the collection frame by twisting.

[0033] The sunshade tube placement mechanism 5 includes a bracket 45, a first grooved cam 46 and a second grooved cam 47 mounted on the bracket 45, a fifth drive motor 48 that drives the first grooved cam 46 and the second grooved cam 47 respectively, and a fourth transmission mechanism that transmits power between the fifth drive motor 48 and the first grooved cam 46 and the second grooved cam 47. The fourth transmission mechanism includes a third drive wheel 49 and a fourth drive wheel 50 mounted on the output end of the fifth drive motor 48, a third driven wheel 51 mounted on the shaft of the first grooved cam 46, a fourth driven wheel 52 mounted on the shaft of the second grooved cam 47, a third synchronous belt 53 that transmits power between the third drive wheel 49 and the third driven wheel 51, and a fourth synchronous belt 54 that transmits power between the fourth drive wheel 50 and the fourth driven wheel 52. The fourth transmission mechanism enables the fifth drive motor 48 to simultaneously drive the first grooved cam 46 and the second grooved cam 47 to rotate in the same direction and at the same frequency. To accommodate the first grooved cam 46 and the second grooved cam 47, the sunshade tube 55 has an added plastic outer edge at the bottom for cooperation, and also an added plastic outer edge in the middle, ensuring a certain gap between the tubes for easy separation. Since the sunshade tube placement mechanism 5 needs to ensure no significant interference during machine movement, it is placed at a certain height above the ground. During a fall, uncontrollable terrain or weather factors may lead to poor placement. Therefore, a counterweight is added to the lower part of the sunshade tube 55 to lower the center of gravity while maintaining a low mass, thus improving placement stability.

[0034] The control system 2 includes a controller and a vision recognition module, a blade life detection module, and a transmission assembly electrically connected to the controller. The transmission assembly includes cameras mounted on the front and rear sides of the frame 1, and encoders for detecting the rotational speeds of the first rear wheel 8 and the second rear wheel 9. The encoders are mounted on the bearing seats of the first rear wheel 8 and the second rear wheel 9 to detect their rotational speeds. By transmitting this speed information to the controller, the steering and rotational speeds of the first rear wheel 8 and the second rear wheel 9 can be adjusted, enabling movement at different angles and directions within a small range. Image acquisition and recognition are achieved through two different cameras. The first method uses a convolutional neural network (CNN) to extract image features using convolutional layers, pooling layers, and fully connected layers. This CNN is trained using a backpropagation algorithm to classify different images identified in the field, ultimately obtaining the target image of chives and determining its location. The CNN model effectively helps us accurately identify the location of chives in the field without interference from other weeds or soil. The second method involves using a camera to identify the harvested chives after the machine has finished harvesting. Upon detection, a stop signal is sent to the entire vehicle, and a placement signal is sent to the sunshade placement mechanism 5. If no chives are detected, the vehicle remains in its original state. The controller receives and processes data from various sensors via a communication protocol, pre-processes the sensor data, and integrates it into the control algorithm. This outputs control signals to drive the drive motors, thereby initiating the mechanical movement of each mechanism and completing its corresponding function. This enables the harvesting of chives and the placement of the sunshade 55 while the machine is in motion. The blade life detection module predicts the lifespan of the currently used blades 22 and provides replacement information to the user, effectively improving the automation level and efficiency of chive harvesting.

Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
