Description

Technical Field

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

[0002] In recent years, the scale of leafy vegetable cultivation has continued to expand. On the one hand, due to the increasing demand for vegetables, consumers' consumption of fresh and healthy leafy vegetables continues to rise. In order to meet market demand, growers continue to expand the planting area.

[0017] S1: Start the servo motor and motor;

[0018] S2: Place the collection frame;

[0019] S3: Mobile cutting.

[0020] The present invention has the following beneficial effects:

[0021] 1. In the present invention, when the motor is started, the motor will drive the bevel gear shaft to rotate through the belt, and the bevel gear shaft will drive the bevel gear on the transmission shaft to rotate when it rotates, and the bevel gear will drive the transmission shaft to rotate synchronously when it rotates, and when the transmission shaft rotates, it will drive the connecting belt to rotate back and forth. At this time, when the connecting belt moves, it will drive the L plate and the rotating bar to rotate through multiple center rods, and when the L plate and the rotating bar rotate, they will drive the toothed rod and the connecting belt on the L plate to rotate, and when the L plate and the rotating bar rotate, they will poke the harvested vegetables. At this time, the cut vegetables will enter between the knife connecting belt and the middle plate under the prying of the L plate and the rotating bar, and then when the L plate drives the toothed rod to rotate the toothed plate on the fixed slide rail, the toothed shaft on the L plate that continues to rotate with the transmission shaft will rotate back and forth on the staggered toothed plate in the fixed slide rail, and when the toothed shaft rotates back and forth, the toothed shaft rotating back and forth will drive the swing The plates rotate synchronously. When the swing plate rotates, the rotation of the swing plate will drive the rotating bar through its bottom to make the rotating bar rotate back and forth on the outer surface of the center rod. At this time, when the L plate and the rotating bar drive the vegetables to between the middle plate and the connecting belt, more vegetables will enter between the two L plates under the rotation of the L plate. At this time, the L plate can play a certain supporting and guiding role for the vegetables and combine with the connecting belt to give the vegetables a certain lateral supporting force, so that they can maintain a relatively upright state and be transported backward, which helps to reduce the probability of vegetable lodging, making the transportation process of vegetables after cutting more orderly, and is conducive to subsequent collection and sorting. At the same time, when the swing plate drives the rotating bar to rotate back and forth, the reciprocating rotation of the rotating bar will stir back and forth at the bottom of the vegetables, so that the residual soil on the vegetables will fall from the gaps between the roots and leaves of the vegetables under the reciprocating rotation of the rotating bar, reducing the amount of soil attached to the vegetables after harvesting and alleviating the difficulty of subsequent vegetable cleaning.

[0022] 2. In the present invention, when the rotating bar reciprocates under the rotation of the swing plate, the rotation of the rotating bar will drive the rotating rod so that the rotating rod is tilted under the rotation of the rotating bar. When the rotating rod is tilted, it will pull the sliding plate to slide downward on the surface of the center rod. When the sliding plate slides downward, the inserted rod inside the sliding plate will rotate along the Z-shaped groove on the outer surface of the center rod while moving downward. When the sliding plate moves downward, the movement of the sliding plate will squeeze the elastic rod. After the elastic rod is squeezed, the middle part of the elastic rod will produce an outward bulging deformation. When the elastic rod bulges outward, the deformed elastic rod will push the flexible belt to fit the surface of the vegetable. Then, when the sliding plate moves downward and rotates along the trajectory of the Z-shaped groove on the center rod, at this time, when the rotating bar rotates, The rotation of the rotating bar will drive the bottom of the flexible belt to deflect synchronously. At the same time, when the rotating bar rotates, the rotation of the sliding disk will be in the opposite direction to the rotating bar. At this time, the rotation of the sliding disk will drive the flexible belt through the rotating bar 2 to make the top of the flexible belt deflect in the opposite direction to the rotating bar. At this time, the flexible belt will be twisted under the rotation of the sliding disk and the rotating bar. This twisting action can break the original tight stacking state between the vegetables to a certain extent, so that the contact point and force direction between the vegetables are constantly changing, so that the vegetables that were originally stacked in parallel may form a staggered state due to the twisting of the flexible belt, thereby dispersing the pressure between the vegetables, reducing the pushing situation, and better maintaining the integrity of the leaves and improving the quality of the vegetables.

[0023] 3. In the present invention, when the sliding plate rotates in the Z-shaped groove on the vertical center rod, the rotation of the sliding plate will drive the limiting ring to rotate synchronously through the limiting rod. Since the flexible belt will tightly fit the surface of the elastic rod when the elastic rod is deformed, when the sliding plate drives the limiting rod to rotate, the rotation of the limiting rod drives the limiting ring to rotate synchronously. When the limiting ring rotates, it will squeeze the convex block at the bottom of the L plate through the arc block at the top. After being squeezed, the arc block on the limiting ring will squeeze the limiting rod. When the arc block on the limiting ring is separated from the convex block, the limiting rod will move up under the action of the spring. When the limiting rod moves up and down, the up and down movement of the limiting rod The movement will drive the limit plate to move up and down synchronously. When the limit plate moves up and down, the up and down movement of the limit plate will drive the two arc plates to rotate up and down on the guide rod. When the arc plate rotates, it will pull the elastic rod through the sliding ring to shake. When the elastic rod shakes, it will drive the flexible belt to shake back and forth on the surface of the vegetables. When the flexible belt shakes on the surface of the vegetables, it can reduce the direct contact area and contact time with the vegetables, thereby reducing the damage caused by friction. At the same time, it also helps to disperse the pressure on the surface of the vegetables, reduce the situation where the vegetable surface is subjected to excessive force when the elastic rod is deformed, and further reduce the risk of damage.

[0024] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] A method for using an electric leafy vegetable harvesting device, the electric leafy vegetable harvesting device comprising the following steps:

[0050] S1: Start the servo motor 204 and the motor 301;

[0051] S2: Place the collection frame;

[0052] S3: Mobile cutting.

[0053] When in use, first start the electric push rod 102 to harvest the vegetables, adjust the distance between the front end of the electric push rod 102 and the vegetables to be cut, and then start the servo motor 204 and the motor 301. When the servo motor 204 rotates, it will drive the C-shaped frame 203 to move back and forth through the short shaft 205. When the C-shaped frame 203 moves back and forth, it will drive the bottom knife holder and the knife plate inside the main body 1 to move quickly. Then, when the motor 301 is started again, the work of the motor 301 will drive the output belt inside the main body 1 to rotate through the transmission roller 105. Then, the staff will place the collection frame on the knife placement plate 103 and start the electric frame 104. Then, the staff will push the front end of the electric frame 104 to make the device move forward and cut the vegetables. Then, the cut vegetables will fall into the knife collection frame through the conveyor belt, completing the purpose of harvesting the vegetables.

[0054] When the motor 301 is started, the motor 301 will drive the bevel gear shaft 303 to rotate through the belt. When the bevel gear shaft 303 rotates, it will drive the bevel gear on the transmission shaft 304 to rotate. When the bevel gear rotates, it will drive the transmission shaft 304 to rotate synchronously. When the transmission shaft 304 rotates, it will drive the connecting belt 305 to rotate back and forth. At this time, when the connecting belt 305 moves, it will drive the L plate 402 and the rotating bar 403 to rotate through multiple center rods 401. When the L plate 402 and the rotating bar 403 rotate, The L plate 402 drives the toothed rod and the connecting belt 305 on the L plate 402 to rotate. When the L plate 402 and the rotating bar 403 rotate, the harvested vegetables are moved. At this time, the cut vegetables enter between the knife connecting belt 305 and the middle plate under the movement of the L plate 402 and the rotating bar 403. Then, when the L plate 402 drives the toothed rod to rotate the toothed plate on the fixed slide rail 306, the toothed shaft on the L plate 402 that continues to rotate with the transmission shaft 304 will rotate back and forth on the staggered toothed plates in the fixed slide rail 306. When the toothed shaft rotates back and forth, The rotating gear shaft will drive the swing plate 404 to rotate synchronously. When the swing plate 404 rotates, the rotation of the swing plate 404 will move the rotating bar 403 through its bottom to make the rotating bar 403 rotate back and forth on the outer surface of the center rod 401. At this time, when the L plate 402 and the rotating bar 403 move the vegetables to between the middle plate and the connecting belt 305, more vegetables will enter between the two L plates 402 under the rotation of the L plate 402. At this time, the L plate 402 can play a certain supporting and guiding role for the vegetables and can be combined with the connecting belt 305 and can give the vegetables A certain lateral supporting force enables the vegetables to maintain a relatively upright state and be transported backwards, which helps to reduce the probability of vegetable lodging and makes the transportation process of vegetables after cutting more orderly, which is conducive to subsequent collection and sorting. At the same time, when the swing plate 404 drives the rotating bar 403 to rotate back and forth, the reciprocating rotation of the rotating bar 403 will stir the bottom of the vegetables back and forth, so that the residual soil on the vegetables falls from the gaps between the roots and leaves of the vegetables under the reciprocating rotation of the rotating bar 403, thereby reducing the amount of soil attached to the vegetables after harvesting and alleviating the difficulty of subsequent vegetable cleaning.

[0055] When the rotating bar 403 reciprocates under the rotation of the swing plate 404, the rotation of the rotating bar 403 will drive the rotating rod 502 so that the rotating rod 502 is in an inclined state under the rotation of the rotating bar 403. When the rotating rod 502 is tilted, it will pull the sliding plate 501 to slide downward on the surface of the center rod 401. When the sliding plate 501 slides downward, the inserted rod inside the sliding plate 501 will rotate while moving downward along the Z-shaped groove on the outer surface of the center rod 401. When the sliding plate 501 moves downward, the movement of the sliding plate 501 will squeeze the elastic rod 601. After the elastic rod 601 is squeezed, the middle part of the elastic rod 601 will produce an outward bulging deformation. When the elastic rod 601 bulges outward, the deformed elastic rod 601 will push the flexible belt 405 to fit the surface of the vegetables. Then, when the sliding plate 501 moves downward and rotates along the trajectory of the Z-shaped groove on the center rod 401, When the movable bar 403 rotates, the rotation of the rotating bar 403 will drive the bottom of the flexible belt 405 to deflect synchronously. At the same time, when the rotating bar 403 rotates, the rotation of the sliding disk 501 will rotate in the opposite direction to the rotating bar 403. At this time, the rotation of the sliding disk 501 will drive the flexible belt 405 through the rotating bar 503, so that the top of the flexible belt 405 will deflect in the opposite direction to the rotating bar 403. At this time, the flexible belt 405 will be twisted under the rotation of the sliding disk 501 and the rotating bar 403. This twisting action can break the original tight stacking state between the vegetables to a certain extent, so that the contact point and force direction between the vegetables are constantly changing, so that the vegetables that were originally stacked in parallel may form a staggered state due to the twisting of the flexible belt 405, thereby dispersing the pressure between the vegetables, reducing the pushing situation, and being able to better maintain the integrity of the leaves and improve the quality of the vegetables.

[0056] When the sliding plate 501 rotates in the Z-shaped groove on the vertical center rod 401, the rotation of the sliding plate 501 will drive the limiting ring 607 to rotate synchronously through the limiting rod 606. Since the flexible belt 405 will fit tightly against the surface of the elastic rod 601 when the elastic rod 601 is deformed, when the sliding plate 501 drives the limiting rod 606 to rotate, the rotation of the limiting rod 606 drives the limiting ring 607 to rotate synchronously. When the limiting ring 607 rotates, the convex block at the bottom of the L plate 402 is squeezed through the arc block at the top. After being squeezed, the arc block on the limiting ring 607 will squeeze the limiting rod 606. When the arc block on the limiting ring 607 is separated from the convex block, the limiting rod 606 will move up under the action of the spring. When the limiting rod 606 moves up and down, the limiting ring 607 The up and down movement of the positioning rod 606 will drive the limiting plate 605 to move up and down synchronously. When the limiting plate 605 moves up and down, the up and down movement of the limiting plate 605 will drive the two arc plates 604 to rotate up and down on the guide rod 603. When the arc plate 604 rotates, it will pull the elastic rod 601 through the sliding ring 602 to shake. When the elastic rod 601 shakes, it will drive the flexible belt 405 to shake back and forth on the surface of the vegetables. When the flexible belt 405 shakes on the surface of the vegetables, it can reduce the direct contact area and contact time with the vegetables, thereby reducing the damage caused by friction. At the same time, it also helps to disperse the pressure on the surface of the vegetables, reduce the situation where the vegetable surface is subjected to excessive force when the elastic rod 601 is deformed, and further reduce the risk of damage.
