Description

Technical Field

[0001] The invention relates to the technical field of vegetable harvesting equipment, and in particular to a cutting device for harvesting leafy vegetables and a use method thereof. Background Art

[0002] The mechanization rate of vegetable harvesting is much smaller than that of tillage and planting. The vegetable harvesting method is still at a low level of semi-manual and semi-mechanized. There are many types of leafy vegetables (such as leeks, lettuce, spinach), and the planting distances of various vegetables are different. There are differences in the planting environment. During the harvesting process, care must be taken not to damage the stems and leaves of the vegetables, which will affect the quality of the vegetables.

[0003] When the equipment is harvesting leeks, the soil where the leeks are planted is relatively soft and not too flat. This may cause the equipment to shake during harvesting, which in turn causes the cutting blade at the bottom to shake, making the bottom of the cut leeks not very flat. At the same time, if the shaking angle is too large, it will also cut the roots of the leeks, affecting the next growth of the leeks. In response to the above problems, the following solutions are proposed. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a cutting device for harvesting leafy vegetables, comprising a frame, a wheel is rotatably connected to the outer wall of the frame, a fixing rod is fixedly connected to the top of the frame, a flexible guide block is fixedly connected to the outer wall of the frame, and a stacking and bundling assembly is fixedly connected to the outer wall of the frame. Since the frame has its own power source, the frame can be driven to move by the wheels;

[0005] The shell mechanism includes a twisted belt, a rotating rod for controlling the rotation of the twisted belt, a first pulley, a second pulley, a belt, a gear, and an anti-sway cutting mechanism for cutting vegetables in the middle of the twisted belt;

[0006] The inner wall of the twisted belt is rotatably connected to the outer wall of the rotating rod, the inner wall of the twisted belt is rotatably connected to the outer wall of pulley one, the outer wall of the rotating rod is rotatably connected to the inner wall of the fixed rod, the bottom of pulley one is rotatably connected to the top of the frame, the side wall of pulley two is fixedly connected to the side wall of the rotating rod, the inner wall of the belt is rotatably connected to the outer wall of pulley two, the inner wall of the belt is rotatably connected to the outer wall of the wheel, and the inner wall of the gear is fixedly connected to the outer wall of the rotating rod.

[0007] Preferably, the anti-sway cutting mechanism includes a fixed ring block fixedly connected to the outer wall of the frame, a rotating column one is rotatably connected to the inner wall of the fixed ring block, a rotating ring block is rotatably connected to the outer wall of the rotating column one, and a rotating column two is rotatably connected to the inner wall of the rotating ring block. When the frame shakes, the fixed ring block is driven to shake synchronously. When the fixed ring block shakes forward and backward, the fixed ring block swings at both ends with the rotating column one as the axis. When the fixed ring block shakes left and right, the rotating ring block is synchronously driven to shake left and right through the rotating column one.

[0008] Preferably, the anti-sway cutting mechanism also includes a central support block fixedly connected to the outer wall of the rotating column two, a counterweight block is fixedly connected to the bottom of the central support block, a fixed bracket one is fixedly connected to the top of the central support block, and a motor is fixedly connected to the top of the fixed bracket one. When the fixed ring block swings left and right, the rotating ring block is synchronously driven to swing left and right through the rotating column one. When the rotating ring block swings left and right, the central support block and the fixed bracket one are kept vertically downward by the counterweight block and are in a relatively horizontal state. The fixed ring block and the rotating ring block swing at both ends with the rotating column two as the axis.

[0009] Preferably, the anti-sway cutting mechanism also includes a bevel gear 1 fixedly connected to the outer wall of the motor, a bevel gear 2 is rotatably connected to the inner wall of the fixed bracket 1, the outer wall of the bevel gear 2 is meshed and connected with the outer wall of the bevel gear 1, and a cutting blade is fixedly connected to the bottom of the bevel gear 2. When the frame moves forward, the land where leeks are planted is not smooth and will cause the rotating ring block to shake, and a central support block is provided. When the frame moves forward, the motor is energized to run, driving the bevel gear 1 to rotate. When the bevel gear 1 rotates, the cutting blade is driven to rotate through the bevel gear 2 to harvest the leeks. Since the soil is relatively soft and not smooth, the frame will shake when it moves forward, and the fixed ring block will shake synchronously when the frame shakes. When shaking back and forth, the central support block and the fixed bracket one are kept vertically downward and in a relatively horizontal state by the action of the counterweight block, and the fixed ring block swings at both ends with the rotating column one as the axis. When the fixed ring block shakes left and right, the rotating ring block is synchronously driven to shake left and right through the rotating column one. When the rotating ring block shakes left and right, the central support block and the fixed bracket one are kept vertically downward and in a relatively horizontal state by the action of the counterweight block, and the fixed ring block and the rotating ring block swing at both ends with the rotating column two as the axis. Through the operation of the above components, the cutting blade can be kept in a relatively horizontal state when cutting the leek, thereby reducing the uneven cutting of the bottom end of the leek and avoiding the cutting blade from cutting the root of the leek when the cutting blade shakes too much, affecting the regrowth of the leek.

[0010] Preferably, the stacking and bundling assembly includes a collecting trough fixedly connected to the outer wall of the frame, a rotating plate 1 is rotatably connected to the inner wall of the collecting trough, a fixed block is fixedly connected to the outer wall of the collecting trough, an arc-shaped telescopic block 1 is fixedly connected to the bottom of the fixed block, and one end of the outer wall of the arc-shaped telescopic block 1 away from the fixed block is fixedly connected to the bottom of the rotating plate 1. After the harvested leeks are transported to the collecting trough by a twisted belt, the top of the rotating plate 1 will be subjected to pressure. When the pressure reaches a maximum, the rotating plate 1 will rotate downward to open the bottom of the collecting trough, and the leeks in the collecting trough will fall down in a pile. At the same time, during the rotation of the rotating plate 1, the hydraulic oil in the arc-shaped telescopic block 1 will be squeezed.

[0011] Preferably, the stacking and bundling assembly also includes an arc spring fixedly connected to the outer wall of the fixed block, the outer wall of the arc spring is fixedly connected to the inner wall of the arc-shaped telescopic block 1, a connecting pipe is fixedly connected to the inner wall of the collecting trough, the inner wall of the connecting pipe is through-connected to the inner wall of the arc-shaped telescopic block 1, a conical head is fixedly connected to the inner wall of the connecting pipe, and a one-way valve is fixedly connected to the inner wall of the conical head. Utilizing the characteristic that leeks will fall into the inside of the collecting trough after being conveyed by the twisted belt, two rotating plates 1 are set. After the harvested leeks are conveyed to the collecting trough by the twisted belt, the top of the rotating plate 1 will be subjected to pressure. When the pressure reaches the maximum, the rotating plate 1 will rotate downward to open the bottom of the collecting trough, and the leeks in the collecting trough will fall down in a pile. At the same time, during the rotation of the rotating plate 1, it will squeeze The hydraulic oil in the arc-shaped telescopic block one enters the arc-shaped telescopic block two through the connecting pipe. After the hydraulic oil enters the arc-shaped telescopic block two, it will extend outward and push the rotating plate two to rotate upward to block the subsequent leeks from continuing to fall. Through the operation of the above components, the leeks can fall down in piles, which is convenient for subsequent collection and bundling, and the weight of each pile of leeks is also controlled to be almost the same, thereby avoiding the leeks from piling up after harvesting, and then having to be bundled in separate piles, and controlling the weight of each bundle, which affects the work efficiency. In addition, when the leeks fall down in piles, the rotating plate two rotating upward can block the leeks from continuing to fall from the twisted belt into the collecting trough, avoid affecting the weight of each pile of leeks, and prevent the leeks from being stuck and damaged when the rotating plate one is reset.

[0012] Preferably, the stacking and bundling assembly also includes a rotating plate 2 rotatably connected to the inner wall of the collecting trough, a telescopic plate is slidably connected to the inner wall of the rotating plate 2, an arc-shaped telescopic block 2 is fixedly connected to the inner wall of the collecting trough, the outer wall of the arc-shaped telescopic block 2 is fixedly connected to the bottom of the rotating plate 2, a connecting groove is provided on the inner wall of the rotating plate 2, and an intermittent scraping assembly is fixedly connected to the outer wall of the rotating plate 2. Utilizing the above-mentioned characteristics that the hydraulic oil will flow into the arc-shaped telescopic block 2 through the connecting pipe, a conical head is provided, and when the hydraulic oil in the arc-shaped telescopic block 1 is squeezed and flows into the arc-shaped telescopic block 2 through the connecting pipe, the hydraulic oil will flow into the arc-shaped telescopic block 2 from the holes at the top of the conical head and the one-way valve. At this time, the hydraulic oil is not affected by the conical head and the flow rate is normal. When the arc-shaped telescopic block 1 is reset by the action of the arc spring, the hydraulic oil flows back. At this time, the hydraulic oil can only flow into the arc-shaped telescopic block 1 through the small hole at the top of the conical head. The flow rate slows down, so that the speed of resetting the rotating plate 1 and the rotating plate 2 is also slowed down. At the same time, after the hydraulic oil enters the arc-shaped telescopic block 2, it will also flow into the interior of the rotating plate 2 through the connecting groove, so that the telescopic plate extends outward to further limit the leeks from falling into the collecting trough. Through the operation of the above-mentioned components, when the rotating plate 1 is opened, the speed is faster to facilitate the falling of leeks in piles. When the rotating plate 1 is closed, its speed is slowed down to avoid the rotating plate 1 closing prematurely when the leeks fall halfway due to the reduction in weight, or even the leeks are stuck, affecting the normal operation of the equipment. In addition, when the rotating plate 2 rotates downward slowly, the leeks will slowly tilt and slide along the edge of the collecting trough to the top of the rotating plate 1, avoiding some accumulated leeks from falling directly downward. Under the action of gravity acceleration, the leeks will fall directly under the rotating plate 1, or be stuck in the middle of the rotating plate 1, affecting the normal operation of the equipment.

[0013] Preferably, the intermittent scraping assembly includes a convex tooth fixedly connected to the outer wall of the rotating plate 2, a rack slidably connected to the inner wall of the collecting groove, a piston plate fixedly connected to the bottom of the rack, the outer wall of the piston plate is slidably connected to the inner wall of the collecting groove, and a fixed bracket 2 is fixedly connected to the top of the collecting groove. When the rotating plate 2 rotates upward, the convex tooth is synchronously driven to rotate. When the convex tooth rotates, the piston plate is moved downward through the rack. When the rotating plate 2 rotates downward, the piston plate is moved upward through the convex tooth and the rack.

[0014] Preferably, the intermittent scraping assembly also includes a U-shaped plate rotatably connected to the inner wall of the second fixed bracket, a scraper is fixedly connected to the outer wall of the U-shaped plate, a hydraulic groove is opened on the inner wall of the collecting groove, and a telescopic rod is slidably connected to the inner wall of the collecting groove. The characteristic that the rotating plate 2 can move the rack up and down when it rotates is utilized. When the rotating plate 2 rotates upward, the piston plate is moved downward through the convex teeth and the rack. When the piston plate moves downward, the hydraulic oil in the hydraulic groove is squeezed to push the telescopic rod to move upward, thereby pushing the U-shaped plate to rotate upward. When the U-shaped plate rotates upward, the scraper is brought into contact with the bottom of the twisted belt. When the twisted belt rotates, the soil on the surface of the twisted belt will be scraped by the scraper and fall downward to The U-shaped plate is prevented from falling onto the convex teeth to hinder the operation of the rotating plate two. When the rotating plate two rotates downward, the piston plate will move upward through the convex teeth and the rack. Since the U-shaped plate is heavier on the side close to the scraper, when the telescopic rod moves downward, the U-shaped plate will also rotate downward, so that the soil that falls into the U-shaped plate can slide into the soil. Through the operation of the above components, the surface of the twisted belt can be scraped and cleaned indirectly, and collected and discharged into the soil, avoiding continuous scraping to cause wear on the surface of the twisted belt and reducing its service life. At the same time, it prevents too much soil from adhering to the twisted belt, reduces the distance between the twisted belts, increases the clamping force on the leek, and thus damages it, affecting subsequent processing.

[0015] A method for using a cutting device for harvesting leafy vegetables comprises the following steps:

[0016] S1: Placing the device: Before using the device, install the device in the required position so that the rows of leeks are in the middle of the flexible guide blocks and remain horizontal;

[0017] S2: Power-on operation: When the frame moves forward, the motor is powered on to drive the bevel gear 1 to rotate. When the bevel gear 1 rotates, the cutting blade is driven to rotate through the bevel gear 2.

[0018] The present invention has the following beneficial effects:

[0019] (1) The present invention utilizes the characteristic that when the frame moves forward, the land where leeks are planted is not very flat, which causes the rotating ring block to shake. A central support block is provided. When the frame moves forward, the motor is powered on to drive the bevel gear 1 to rotate. When the bevel gear 1 rotates, the cutting blade is driven to rotate by the bevel gear 2 to harvest the leeks. Since the soil is relatively soft and not very flat, the frame will shake when it moves forward. When the frame shakes, the fixed ring block is driven to shake synchronously. When the fixed ring block shakes forward and backward, the central support block and the fixed bracket 1 are kept vertically downward by the counterweight block and are in a relatively horizontal state. The ring block swings at both ends with the rotating column one as the axis. When the fixed ring block swings left and right, the rotating ring block is synchronously driven to swing left and right through the rotating column one. When the rotating ring block swings left and right, the central support block and the fixed bracket one are kept vertically downward by the counterweight block and are in a relatively horizontal state. The fixed ring block and the rotating ring block swing at both ends with the rotating column two as the axis. Through the operation of the above components, the cutting blade can keep a relatively horizontal state when cutting the leek, thereby reducing the uneven cutting of the bottom end of the leek and avoiding the cutting blade from cutting the root of the leek when the cutting blade swings too much, affecting the regrowth of the leek.

[0020] (2) The present invention utilizes the characteristic that leeks will fall into the collecting trough after being conveyed by a twisted belt, and two rotating plates 1 are provided. After the harvested leeks are conveyed to the collecting trough by the twisted belt, the top of the rotating plate 1 will be subjected to pressure. When the pressure reaches the maximum, the rotating plate 1 will rotate downward to open the bottom of the collecting trough, and the leeks in the collecting trough will fall down in a pile. At the same time, during the rotation of the rotating plate 1, the hydraulic oil in the arc-shaped telescopic block 1 will be squeezed to enter the arc-shaped telescopic block 2 through the connecting pipe. After the hydraulic oil enters the arc-shaped telescopic block 2, it will extend outward and push the rotating plate 2. The leeks are then bundled together and the weight of each bundle is controlled to be almost the same, thereby avoiding the leeks from piling up after harvesting and then having to be bundled separately and the weight of each bundle being controlled, which affects the work efficiency. In addition, when the leeks fall down in bundles, the upwardly rotating rotating plate 2 can block the leeks from continuing to fall from the twisted belt into the collecting trough, thereby avoiding affecting the weight of each bundle of leeks and preventing the leeks from being stuck and damaged when the rotating plate 1 is reset.

[0021] (3) The present invention utilizes the above-mentioned characteristic that the hydraulic oil will flow into the arc-shaped telescopic block 2 through the connecting pipe, and sets a conical head. When the hydraulic oil in the arc-shaped telescopic block 1 is squeezed and flows into the arc-shaped telescopic block 2 through the connecting pipe, the hydraulic oil will flow into the arc-shaped telescopic block 2 from the hole at the top of the conical head and the one-way valve. At this time, the hydraulic oil is not affected by the conical head and the flow rate is normal. When the arc-shaped telescopic block 1 is reset by the action of the arc spring, the hydraulic oil flows back. At this time, the hydraulic oil can only flow into the arc-shaped telescopic block 1 through the small hole at the top of the conical head, and the flow rate is slowed down, so that the reset speed of the rotating plate 1 and the rotating plate 2 is also slowed down. At the same time, after the hydraulic oil enters the arc-shaped telescopic block 2, it will also flow into the interior of the rotating plate 2 through the connecting groove. The telescopic plate is extended outward to further restrict the leeks from falling into the collecting trough. Through the operation of the above components, when the rotating plate 1 is opened, the speed is faster to facilitate the falling of the leeks in piles. When the rotating plate 1 is closed, its speed is slowed down to avoid the rotating plate 1 closing in advance when the leeks are halfway down due to the reduction in weight, or even the leeks being stuck, affecting the normal operation of the equipment. In addition, when the rotating plate 2 is rotated downward slowly, the leeks are slowly tilted and slide along the edge of the collecting trough to the top of the rotating plate 1, so that some accumulated leeks are prevented from falling directly downward. Under the action of gravity acceleration, the leeks are allowed to fall directly under the rotating plate 1, or are stuck in the middle of the rotating plate 1, affecting the normal operation of the equipment.

[0022] (4) The present invention utilizes the characteristic that the rotating plate 2 will move the rack up and down when it rotates. When the rotating plate 2 rotates upward, the convex teeth and the rack will cause the piston plate to move downward. When the piston plate moves downward, the hydraulic oil in the hydraulic groove is squeezed to push the telescopic rod upward, thereby pushing the U-shaped plate to rotate upward. When the U-shaped plate rotates upward, the scraper will contact the bottom of the twisted belt. When the twisted belt rotates, the soil on the surface of the twisted belt will be scraped by the scraper and fall downward into the U-shaped plate to prevent it from falling onto the convex teeth, thereby obstructing the operation of the rotating plate 2. When the rotating plate 2 rotates downward, the scraper will contact the bottom of the twisted belt. When the twisted belt rotates, the soil on the surface of the twisted belt will be scraped by the scraper and fall downward into the U-shaped plate to prevent it from falling onto the convex teeth, thereby obstructing the operation of the rotating plate 2. The convex teeth and the rack will cause the piston plate to move upward. Since the side of the U-shaped plate close to the scraper is heavier, when the telescopic rod moves downward, the U-shaped plate will also rotate downward, so that the soil that falls into the U-shaped plate can slide into the soil. Through the operation of the above components, the surface of the twisted belt can be scraped and cleaned indirectly, and the soil can be collected and discharged into the soil, so as to avoid continuous scraping to cause wear on the surface of the twisted belt and reduce its service life. At the same time, it prevents too much soil from sticking to the twisted belt, reduces the distance between the twisted belts, and increases the clamping force on the leek, which will cause it to be damaged and affect subsequent processing.

[0042] The anti-shaking cutting mechanism 3 also includes a bevel gear 1 309 fixedly connected to the outer wall of the motor 308, and a bevel gear 2 310 is rotatably connected to the inner wall of the fixed bracket 1 307. The outer wall of the bevel gear 2 310 is meshed and connected with the outer wall of the bevel gear 1 309, and a cutting blade 311 is fixedly connected to the bottom of the bevel gear 2 310.

When the fixed ring block 301 swings left and right, the rotating ring block 303 is synchronously driven to swing left and right through the rotating column 1 302. When the rotating ring block 303 swings left and right, the central support block 305 and the fixed bracket 1 307 are kept vertically downward and in a relatively horizontal state by the action of the counterweight block 306, and the fixed ring block 301 and the rotating ring block 303 swing at both ends with the rotating column 2 304 as the axis. Through the operation of the above-mentioned components, the cutting blade 311 can be kept in a relatively horizontal state when cutting the leek, thereby reducing the uneven cutting of the bottom end of the leek, and at the same time avoiding the cutting blade 311 from cutting the root of the leek when the cutting blade 311 swings too much, affecting the regrowth of the leek.

[0043] For example 2, please refer to Figure 4 - Fig.10 The present invention is a cutting device for harvesting leafy vegetables.

One end of the outer wall of the arc-shaped telescopic block 404 away from the fixed block 403 is fixedly connected to the bottom of the rotating plate 402. After the harvested leeks are transported to the collecting trough 401 by the twisted belt 201, the top of the rotating plate 402 will be subjected to pressure. When the pressure reaches the maximum, the rotating plate 402 will rotate downward to open the bottom of the collecting trough 401, and the leeks in the collecting trough 401 will fall down in a pile. At the same time, during the rotation of the rotating plate 402, the hydraulic oil in the arc-shaped telescopic block 404 will be squeezed.

[0044] The stacking and bundling component 4 also includes an arc spring 405 fixedly connected to the outer wall of the fixed block 403, the outer wall of the arc spring 405 is fixedly connected to the inner wall of the arc telescopic block 404, the inner wall of the collecting trough 401 is fixedly connected with a connecting pipe 406, the inner wall of the connecting pipe 406 is through-connected with the inner wall of the arc telescopic block 404, the inner wall of the connecting pipe 406 is fixedly connected with a conical head 407, and the inner wall of the conical head 407 is fixedly connected with a one-way valve 408. Taking advantage of the fact that leeks will fall into the inside of the collecting trough 401 after being conveyed by the twisted belt 201, two rotating plates 402 are set. After the harvested leeks are conveyed to the collecting trough 401 by the twisted belt 201, the top of the rotating plate 402 will be subjected to pressure. When the pressure reaches the maximum, the rotating plate 402 will rotate downward to open the bottom of the collecting trough 401, and the leeks in the collecting trough 401 will fall down in a pile. At the same time, during the rotation of the rotating plate 1 402, the hydraulic oil in the arc-shaped telescopic block 1 404 will be squeezed to enter the arc-shaped telescopic block 2 411 through the connecting pipe 406. After the hydraulic oil enters the arc-shaped telescopic block 2 411, it will extend outward and push the rotating plate 2 409 to rotate upward to prevent the subsequent leeks from continuing to fall. Through the operation of the above components, the leeks can fall down in piles, which is convenient for subsequent collection and bundling, and the weight of each pile of leeks is also controlled to be almost the same, thereby avoiding the leeks from piling up after harvesting, and then needing to be bundled in separate piles, and controlling the weight of each bundle, which affects the work efficiency. In addition, when the leeks fall down in piles, the rotating plate 2 409 rotating upward can prevent the leeks from continuing to fall from the twisted belt 201 to the collecting trough 401, avoid affecting the weight of each pile of leeks, and prevent the leeks from being stuck and damaged when the rotating plate 1 402 is reset.

[0045] The stacking and bundling assembly 4 also includes a rotating plate 409 rotatably connected to the inner wall of the collecting tank 401, a telescopic plate 410 is slidably connected to the inner wall of the rotating plate 409, an arc-shaped telescopic block 411 is fixedly connected to the inner wall of the collecting tank 401, and the outer wall of the arc-shaped telescopic block 411 is fixedly connected to the bottom of the rotating plate 409, a connecting groove 412 is opened on the inner wall of the rotating plate 409, and an intermittent scraping assembly 5 is fixedly connected to the outer wall of the rotating plate 409. By using the above, the hydraulic oil will flow into the connecting pipe 406 through the connecting pipe The characteristic of the arc telescopic block 411 is that a conical head 407 is provided. When the hydraulic oil in the arc telescopic block 1 404 is squeezed and flows into the arc telescopic block 2 411 through the connecting pipe 406, the hydraulic oil will flow into the arc telescopic block 2 411 from the hole at the top of the conical head 407 and the one-way valve 408. At this time, the hydraulic oil is not affected by the conical head 407 and the flow rate is normal. When the arc telescopic block 1 404 is reset by the arc spring 405, the hydraulic oil flows back. At this time, the hydraulic oil can only flow through the small hole at the top of the conical head 407. The hydraulic oil flows into the arc-shaped telescopic block 1 404, and the flow rate slows down, so that the speed of resetting the rotating plate 1 402 and the rotating plate 2 409 is also slowed down. At the same time, after the hydraulic oil enters the arc-shaped telescopic block 2 411, it will also flow into the interior of the rotating plate 2 409 through the connecting groove 412, so that the telescopic plate 410 extends outward to further limit the leeks from falling into the collecting groove 401. Through the operation of the above components, when the rotating plate 1 402 is opened, the speed is faster to facilitate the falling of the leeks in piles, and when the rotating plate 1 402 is closed, its speed is slowed down. , to avoid the rotating plate 402 closing prematurely or even getting the leeks stuck when the leeks are halfway down due to the reduction in weight, thus affecting the normal operation of the equipment. In addition, when the rotating plate 409 rotates downward slowly, the leeks will slowly tilt and slide along the edge of the collecting trough 401 to the top of the rotating plate 402, thus preventing some accumulated leeks from falling directly downward. Under the action of gravity acceleration, the leeks will fall directly under the rotating plate 402 or get stuck in the middle of the rotating plate 402, thus affecting the normal operation of the equipment.

[0046] The intermittent scraping assembly 5 includes a convex tooth 501 fixedly connected to the outer wall of the rotating plate 409, a rack 502 slidably connected to the inner wall of the collecting groove 401, a piston plate 503 fixedly connected to the bottom of the rack 502, the outer wall of the piston plate 503 is slidably connected to the inner wall of the collecting groove 401, and a fixed bracket 2 504 is fixedly connected to the top of the collecting groove 401. When the rotating plate 409 rotates upward, the convex tooth 501 is synchronously driven to rotate. When the convex tooth 501 rotates, the piston plate 503 is moved downward through the rack 502. When the rotating plate 409 rotates downward, the piston plate 503 is moved upward through the convex tooth 501 and the rack 502.

[0047] The intermittent scraping assembly 5 also includes a U-shaped plate 505 rotatably connected to the inner wall of the second fixed bracket 504, a scraper 506 is fixedly connected to the outer wall of the U-shaped plate 505, a hydraulic groove 507 is provided on the inner wall of the collecting tank 401, and a telescopic rod 508 is slidably connected to the inner wall of the collecting tank 401. The rotating plate 409 is used to make the rack 502 move up and down when it rotates. When the rotating plate 409 rotates upward, the piston plate 503 is moved downward by the convex teeth 501 and the rack 502. When the piston plate 503 moves downward, the hydraulic oil in the hydraulic groove 507 is squeezed to push the telescopic rod 508 to move upward, thereby pushing the U-shaped plate 505 to rotate upward. When the U-shaped plate 505 rotates upward, the scraper 506 is brought into contact with the bottom of the twisted belt 201. When the twisted belt 201 rotates, the soil on the surface of the twisted belt 201 is scraped by the scraper 5. 06 scrapes and falls downward into the U-shaped plate 505 to prevent it from falling onto the convex teeth 501, which would hinder the operation of the rotating plate 209. When the rotating plate 209 rotates downward, the convex teeth 501 and the rack 502 will cause the piston plate 503 to move upward. Since the side of the U-shaped plate 505 close to the scraper 506 is heavier, when the telescopic rod 508 moves downward, the U-shaped plate 505 will also rotate downward, so that the soil that falls into the U-shaped plate 505 can slide into the soil. Through the operation of the above components, the surface of the twisted belt 201 can be scraped and cleaned indirectly, and collected and discharged into the soil, so as to avoid continuous scraping that causes the surface of the twisted belt 201 to be worn and its service life to be reduced. At the same time, it prevents too much soil from adhering to the twisted belt 201, reduces the distance between the twisted belts 201, increases the clamping force on the leek, and thus damages it, affecting subsequent processing.

[0048] The method for using the cutting device for harvesting leafy vegetables comprises the following steps:

[0049] S1: Placing the device: Before using the device, first install the device at the required position so that the rows of leeks are in the middle of the flexible guide block 103 and remain horizontal;

[0050] S2: Power on and run: When the vehicle frame 1 moves forward, the motor 308 is powered on and runs, driving the bevel gear 1 309 to rotate. When the bevel gear 1 309 rotates, the cutting blade 311 is driven to rotate through the bevel gear 2 310 .

[0051] A specific application of this embodiment is: before using the device, the device is first installed at the required position, so that the rows of leeks are in the middle of the flexible guide block 103, keep it horizontal, and turn on the power of the motor 308. When the frame 1 moves forward, the motor 308 is powered on to drive the bevel gear 1 309 to rotate. When the bevel gear 1 309 rotates, the cutting blade 311 is driven to rotate through the bevel gear 2 310 to harvest the leeks. Since the soil is relatively soft and not very flat, the frame 1 will shake when it moves forward. When the frame 1 shakes, the fixed ring block 301 is driven to shake synchronously. When the fixed ring block 301 shakes forward and backward, the central support block 305 and the fixed bracket 1 307 are kept vertically downward by the counterweight block 306 and are in a relatively horizontal state. The fixed ring block 30 The rotating ring block 303 is driven to swing left and right by the rotating column 1 302 when the fixed ring block 301 swings left and right. When the rotating ring block 303 swings left and right, the central support block 305 and the fixed bracket 1 307 are kept vertically downward by the counterweight block 306 and are in a relatively horizontal state. The fixed ring block 301 and the rotating ring block 303 swing with the rotating column 2 304 as the axis. Through the operation of the above components, the cutting blade 311 can keep a relatively horizontal state when cutting the leek, so as to avoid the cutting blade 311 from shaking synchronously when the frame 1 shakes, so that the bottom of the cut leek is not very flat. At the same time, when the cutting blade 311 shakes too much, the cutting blade 311 will cut the root of the leek, affecting the regrowth of the leek.

[0052] Taking advantage of the fact that the leeks will fall into the collecting tank 401 after being conveyed by the twisted belt 201, two rotating plates 1 402 are provided. After the harvested leeks are conveyed to the collecting tank 401 by the twisted belt 201, the top of the rotating plate 1 402 will be subjected to pressure. When the pressure reaches the maximum, the rotating plate 1 402 will rotate downward to open the bottom of the collecting tank 401, and the leeks in the collecting tank 401 will fall down in a pile. At the same time, during the rotation of the rotating plate 1 402, the hydraulic oil in the arc-shaped telescopic block 1 404 will be squeezed to enter the arc-shaped telescopic block 2 411 through the connecting pipe 406. After the hydraulic oil enters the arc-shaped telescopic block 2 411, it will extend outward and push the rotating plate 2 409 The leeks are then bundled together and the weight of each bundle is controlled to be almost the same, thereby avoiding the leeks from piling up after harvesting and then having to be bundled separately and the weight of each bundle being controlled to affect the work efficiency. In addition, when the leeks fall down in bundles, the rotating plate 209 rotating upward can block the leeks from continuing to fall from the twisted belt 201 to the collecting trough 401, thereby avoiding affecting the weight of each bundle of leeks and preventing the leeks from being stuck and damaged when the rotating plate 1 402 is reset. The hydraulic oil in the arc-shaped telescopic block 1 404 is squeezed and the hydraulic oil is released through the connecting pipe 40 6 When flowing into the arc telescopic block 2 411, the hydraulic oil will flow into the arc telescopic block 2 411 from the hole at the top of the conical head 407 and the one-way valve 408. At this time, the hydraulic oil is not affected by the conical head 407, and the flow rate is normal. When the arc telescopic block 1 404 is reset by the action of the arc spring 405, the hydraulic oil flows back. At this time, the hydraulic oil can only flow into the arc telescopic block 1 404 through the small hole at the top of the conical head 407, and the flow rate is slowed down, so that the reset speed of the rotating plate 1 402 and the rotating plate 2 409 is also slowed down. At the same time, after the hydraulic oil enters the arc telescopic block 2 411, it will also flow into the interior of the rotating plate 2 409 through the connecting groove 412, so that the telescopic plate 410 extends outward, so as to further limit the flow of leeks to the collecting groove 4 01 falls, through the operation of the above components, when the rotating plate 402 is opened, the speed is faster to facilitate the falling of the leeks in piles, and when the rotating plate 402 is closed, its speed is slowed down to avoid the rotating plate 402 closing in advance when the leeks are halfway down due to the reduction in weight, or even the leeks are stuck, affecting the normal operation of the equipment. In addition, when the rotating plate 409 rotates downward slowly, the leeks will slowly tilt and slide along the edge of the collecting trough 401 to the top of the rotating plate 402, avoiding some of the accumulated leeks from falling directly downward. Under the action of gravity acceleration, the leeks will fall directly to the bottom of the rotating plate 402, or be stuck in the middle of the rotating plate 402, affecting the normal operation of the equipment.

[0053] Taking advantage of the fact that the rack 502 moves up and down when the rotating plate 409 rotates, when the rotating plate 409 rotates upward, the piston plate 503 moves downward through the convex teeth 501 and the rack 502. When the piston plate 503 moves downward, the hydraulic oil in the hydraulic groove 507 is squeezed to push the telescopic rod 508 to move upward, thereby pushing the U-shaped plate 505 to rotate upward. When the U-shaped plate 505 rotates upward, the scraper 506 contacts the bottom of the twisted belt 201. When the twisted belt 201 rotates, the soil on the surface of the twisted belt 201 is scraped by the scraper 506 and falls downward into the U-shaped plate 505 to prevent it from falling on the convex teeth 501, thereby obstructing the operation of the rotating plate 409. 09 When rotating downward, the piston plate 503 will move upward through the convex teeth 501 and the rack 502. Since the side of the U-shaped plate 505 close to the scraper 506 is heavier, when the telescopic rod 508 moves downward, the U-shaped plate 505 will also rotate downward, so that the soil that falls into the U-shaped plate 505 can slide into the soil. Through the operation of the above components, the surface of the twisted belt 201 can be scraped and cleaned indirectly, and collected and discharged into the soil, so as to avoid continuous scraping to cause wear on the surface of the twisted belt 201 and reduce its service life. At the same time, it prevents too much soil from adhering to the twisted belt 201, reduces the distance between the twisted belts 201, and increases the clamping force on the leek, which will cause it to be damaged and affect subsequent processing.
