Description

Technical Field

[0001] The present invention relates to the technical field of rapeseed planting, and particularly relates to a device for detecting leaf diseases in rapeseed planting. Background Art

[0002] Rapeseed, also known as green vegetables, pakchoi, etc., has elliptical leaves, thick petioles, dark green color, a tufted plant type, is beautiful and neat, has fine fibers, and a sweet taste and good texture. During the process of rapeseed planting, it is necessary to regularly check the rapeseed leaves. According to the detection results, corresponding pesticides are sprayed on the rapeseed to reduce the threat of pests and diseases to the rapeseed and maintain the normal quality of the rapeseed.

[0003] During the detection process of rapeseed leaves, the rapeseed leaves are mainly photographed by a camera, and analysis and comparison are carried out based on the obtained photos, and finally the disease detection operation is completed. The overall operation is simple. However, in the actual detection process, it is mainly carried out by hand-held shooting by workers. The workers need to bend down to take pictures. During the long shooting process, it is quite tiring. And during the shooting process, in order to better and more comprehensively complete the shooting operation of the leaves, it is also necessary to manually shake the leaves, which is time-consuming and laborious, and is very likely to cause certain damage to the leaves due to excessive force. Therefore, a device for detecting leaf diseases in rapeseed planting is provided. Summary of the Invention

[0004] The purpose of the present invention is to solve the drawbacks existing in the prior art, and a device for detecting leaf diseases in rapeseed planting is proposed.

A shaking component for controlling the shaking of rapeseed leaves is installed inside the bracket. The shaking component includes a biaxial motor fixedly installed inside the bracket. Both output ends of the biaxial motor are fixedly installed with reciprocating lead screws. A slider is threadedly sleeved on the outer side of the reciprocating lead screw. The slider penetrates through the bracket and is slidably connected to the bracket. A sliding rod is fixedly connected to the lower side of the slider. A moving cylinder is fixedly connected to the lower side of the sliding rod. A square rod is sleeved inside the moving cylinder. One end of the square rod far away from the moving cylinder is fixedly connected to a fixing plate. A first spring is fixedly connected between the fixing plate and the moving cylinder. A shaking plate is fixedly connected to the side of the fixing plate far away from the moving cylinder.

[0007] Preferably, a rotating assembly for controlling the rotation of the camera is installed on the outer side of the moving cylinder. The rotating assembly includes multiple fixed gantry rods fixedly installed on the inner side of the bracket. A rotating cylinder is rotatably sleeved on the outer sides of the multiple fixed gantry rods. A first gear is fixedly sleeved on the outer side of the rotating cylinder. A first rack is meshed and connected to the lower side of the first gear. The first rack is fixedly connected to the moving cylinder through a connecting rod. A rotating gantry rod is fixedly connected to the outer side of the rotating cylinder. The rotating gantry rod is fixedly connected to the camera.

[0008] Preferably, a sliding plate is slidably connected inside the moving cylinder. A hydraulic rod is fixedly connected to the side wall of the sliding plate. The output end of the hydraulic rod is fixedly connected to a square rod. A button for controlling the switch of the hydraulic rod is fixedly installed on the outer side of the square rod.

[0009] Preferably, a control assembly for controlling the movement of the shaking plate is installed on the outer side of the moving cylinder. The control assembly includes a rotating plate fixedly sleeved on the outer side of the reciprocating lead screw. Multiple rotating rods are fixedly connected circumferentially on the outer side of the rotating plate. A fixed frame is fixedly connected to the side wall of the sliding plate. A connecting plate is sleeved inside the fixed frame. A control plate is fixedly connected to the upper side of the connecting plate. An inclined plate is slidably sleeved on the side wall of the control plate. Two sets of clamping plates are symmetrically and fixedly connected to the outer side of the bracket. Inclined grooves are formed on the side walls of the two sets of clamping plates. The inclined plate is slidably connected to the inclined grooves. Two positioning rods are fixedly sleeved on the side wall of the inclined plate. The lower sides of the two positioning rods are slidably connected to the same positioning plate. Two third racks are fixedly connected to the side wall of the positioning plate. The two third racks are slidably connected to the side wall of the moving cylinder. Two circular plates are symmetrically and fixedly connected to the outer side of the moving cylinder. A same guiding rod is fixedly connected between the two circular plates. A gear cylinder is rotatably sleeved on the outer side of the guiding rod. The third rack is meshed with the gear cylinder. Two fixed rods are fixedly connected to the side wall of the fixing plate. A second rack is fixedly connected to the side walls of the two fixed rods. The second rack is meshed with the gear cylinder.

[0010] Preferably, a limiting rod is slidably sleeved on the side wall of the square rod. Limiting plates are fixedly connected to both ends of the limiting rod. A second spring is fixedly connected between the limiting plate and the square rod. The limiting plate is slidably connected to the side wall of the moving cylinder.

[0011] Preferably, a second gear is also fixedly sleeved on the outer side of the reciprocating lead screw. Two transmission rods are rotatably connected to the outer side of the bracket. Third gears are fixedly sleeved on the outer sides of the two transmission rods. The third gear is meshed with the second gear. Multiple bearings are rotatably installed on the side wall of the bracket. Wheels are fixedly installed on the outer sides of the multiple bearings. A pulley assembly is sleeved between the transmission rod and the bearing.

[0012] Preferably, the cross-section of the side of the shaking plate away from the square cylinder is conical.

[0013] The beneficial effects of the present invention are:

[0014] 1. First, when it is necessary to detect diseases on rapeseed leaves, place the device as a whole on the field, start the dual-axis motor, and then drive the device as a whole to move. In the process, the reciprocating screw rod and slider and other components will also drive the shaking plate to move. The shaking plate and the rapeseed leaves will be against each other, and drive the rapeseed leaves to shake, thereby improving the camera's shooting effect on the rapeseed leaves. The staff does not need to touch the rapeseed leaves with their hands, and the degree of intelligence is relatively high.

[0015] 2. At the same time, the rotating cylinder drives the rotating gantry rod and the camera to rotate back and forth with the rotating cylinder as the center, thereby increasing the shooting range of the camera, thereby better completing the shooting and detection operation of rapeseed leaves and ensuring the detection effect;

[0016] 3. In addition, during this process, if the shaking board encounters a large resistance from the rapeseed leaves, it means that the shaking board has been against the rapeseed stems and leaves. At this time, the shaking board is quickly disconnected from the rapeseed, and will not cause damage to the rapeseed leaves due to continuous force on the rapeseed leaves. The intelligent level is relatively high.

[0017] 4. Finally, during the movement of the shaking board, the shaking board will also cause the rapeseed leaves to move slightly, preventing obstacles accidentally accumulated on the outside of the rapeseed leaves from affecting the later detection results during the detection of the rapeseed leaves, thereby ensuring the accuracy of the detection results. As the rapeseed leaves hinder the shaking board more, the control board moves a greater distance to the lower left, the contact time between the control board and the rotating rod is shorter, and the shaking amplitude of the shaking board is smaller, reducing damage to the rapeseed leaves.

Specific embodiments

[0028] Refer to Figures 1-9 , a leaf disease detection device for rapeseed planting, including a bracket 1 and multiple groups of cameras 3;

[0029] Use multiple groups of cameras 3 to complete the shooting operation of rapeseed leaves, and can transmit the obtained information to the corresponding controller (such as a computer), and then analyze and compare it, so as to complete the leaf disease detection operation. The above are all prior arts and will not be elaborated further;

[0030] Such as Figure 2 , Figure 3 , Figure 4, a shaking component 5 for controlling the shaking of rapeseed leaves is installed inside the bracket 1. The shaking component 5 includes a double-shaft motor 2 fixedly installed inside the bracket 1. Reciprocating lead screws 501 are fixedly installed at both output ends of the double-shaft motor 2. A slider 502 is threadedly sleeved outside the reciprocating lead screw 501. The slider 502 penetrates through the bracket 1 and is slidably connected to the bracket 1. A sliding rod 505 is fixedly connected to the lower side of the slider 502. A moving cylinder 504 is fixedly connected to the lower side of the sliding rod 505. A square rod 506 is sleeved inside the moving cylinder 504. One end of the square rod 506 away from the moving cylinder 504 is fixedly connected to a fixing plate 507. A first spring 508 is fixedly connected between the fixing plate 507 and the moving cylinder 504. A shaking plate 503 is fixedly connected to one side of the fixing plate 507 away from the moving cylinder 504;

[0031] When it is necessary to perform the disease detection operation on rapeseed leaves, start the double-shaft motor 2. The double-shaft motor 2 drives the reciprocating lead screw 501 to rotate. Since the slider 502 is slidably connected to the bracket 1, the rotating reciprocating lead screw 501 will drive the slider 502 to move back and forth left and right relative to the bracket 1. The slider 502 drives the moving cylinder 504 to move back and forth left and right through the sliding rod 505. The moving cylinder 504 drives the fixing plate 507 to move back and forth left and right through the first spring 508. The fixing plate 507 drives the shaking plate 503 to move back and forth left and right. The shaking plate 503 abuts against the rapeseed leaves and drives the rapeseed leaves to shake, thereby improving the shooting effect of the camera 3 on the rapeseed leaves. It is not necessary for the staff to touch the rapeseed leaves by hand, and the degree of intelligence is relatively high.

[0032] Such as Figure 4 , a rotating component for controlling the rotation of the camera 3 is installed outside the moving cylinder 504. The rotating component includes multiple groups of fixed gantry rods 509 fixedly installed inside the bracket 1. A rotating cylinder 510 is rotatably sleeved outside the multiple groups of fixed gantry rods 509. A first gear 511 is fixedly sleeved outside the rotating cylinder 510. A first rack 513 is meshed and connected to the lower side of the first gear 511. The first rack 513 is fixedly connected to the moving cylinder 504 through a connecting rod. A rotating gantry rod 512 is fixedly connected to the outside of the rotating cylinder 510. The rotating gantry rod 512 is fixedly connected to the camera 3. The cross-section of one side of the shaking plate 503 away from the square cylinder is conical;

[0033] During the process of the moving cylinder 504 moving back and forth left and right, the moving cylinder 504 drives the first rack 513 to move back and forth left and right through the connecting rod. The first rack 513 drives the first gear 511 and the rotating cylinder 510 to rotate back and forth with the fixed gantry rod 509 as the center. The rotating cylinder 510 drives the rotating gantry rod 512 and the camera 3 to rotate back and forth with the rotating cylinder 510 as the center, improving the shooting range of the camera 3, and thus can better complete the shooting and detection operation of rapeseed leaves and ensure the detection effect.

[0034] Such asFigure 5 Inside the moving cylinder 504, a sliding plate 517 is slidably connected. The sliding direction of the sliding plate 517 and the moving cylinder 504 is perpendicular to the sliding direction of the square rod 506 and the moving cylinder 504. A hydraulic rod 518 is fixedly connected to the side wall of the sliding plate 517. The output end of the hydraulic rod 518 is fixedly connected to the square rod 506. A button 519 for controlling the switch of the hydraulic rod 518 is fixedly installed on the outside of the square rod 506;

[0035] First of all, the button 519 can control the opening and closing of the hydraulic rod 518, and the button 519 is a touch delay switch in real life. The touch delay switch will only be triggered for a period of time after being pressed, and no matter how long the pressing time is, it will only be triggered for a period of time. When the moving cylinder 504 drives the shaking plate 503 to move back and forth through the first spring 508 and the fixing plate 507, when the shaking plate 503 abuts against the rape leaf, during the continuous movement of the shaking plate 503, when the shaking plate 503 gradually moves towards the direction close to the rape stem, the shaking plate 503 will be blocked by the rape stem, preventing the shaking plate 503 from following the moving cylinder 504 to move. The first spring 508 is compressed, and the whole of the shaking plate 503, the fixing plate 507 and the square rod 506 moves leftward relative to the moving cylinder 504. When the button 519 enters the moving cylinder 504, the button 519 abuts against the moving cylinder 504 and is pressed by the moving cylinder 504. At this time, the hydraulic rod 518 is started, and the whole of the shaking plate 503, the square rod 506 and the fixed rod 523 will move leftward and disconnect from the rape leaf. When the control time of the button 519 ends, at this time, the moving cylinder 504 is in the state of moving leftward. The whole of the shaking plate 503, the square rod 506 and the fixed rod 523 returns to its original position relative to the moving cylinder 504 under the action of the first spring 508. Finally, when the shaking plate 503 abuts against the rape leaf and drives the rape leaf to move, if the resistance of the rape leaf is large, it means that the shaking plate 503 has abutted against the rape stem and leaves. At this time, the shaking plate 503 quickly disconnects from the rape under the action of the hydraulic rod 518, and will not cause damage to the rape leaf due to continuously applying force to the rape leaf, with a high degree of intelligence.

[0036] Such as Figure 5 、 Figure 6 、 Figure 7 、 Figure 8, a control component for controlling the movement of the shaking plate 503 is installed outside the moving cylinder 504. The control component includes a rotating plate 514 fixedly sleeved outside the reciprocating lead screw 501. A plurality of rotating rods 516 are fixedly connected circumferentially outside the rotating plate 514. A fixed frame 515 is fixedly connected to the side wall of the sliding plate 517. A connecting plate 524 is sleeved inside the fixed frame 515. A control plate 525 is fixedly connected to the upper side of the connecting plate 524. An inclined plate 529 is slidably sleeved on the side wall of the control plate 525. Two groups of clamping plates 527 are symmetrically and fixedly connected to the outside of the bracket 1. Oblique grooves 528 are formed in the side walls of the two groups of clamping plates 527. The inclined plate 529 is slidably connected with the oblique grooves 528. Two groups of positioning rods 526 are fixedly sleeved on the side wall of the inclined plate 529. The lower sides of the two groups of positioning rods 526 are slidably connected with the same positioning plate 534. Based on Figure 7 the direction, the positioning rod 526 and the positioning plate 534 are slidably connected left and right. Two groups of third racks 533 are fixedly connected to the side wall of the positioning plate 534. The two groups of third racks 533 are slidably connected with the side wall of the moving cylinder 504. Two groups of circular plates 535 are symmetrically and fixedly connected to the outside of the moving cylinder 504. The same guide rod 530 is fixedly connected between the two groups of circular plates 535. A gear cylinder 531 is rotatably sleeved on the outside of the guide rod 530. The third rack 533 is meshed with the gear cylinder 531. Two groups of fixed rods 523 are fixedly connected to the side wall of the fixed plate 507. A second rack 532 is fixedly connected to the side walls of the two groups of fixed rods 523. The second rack 532 is meshed with the gear cylinder 531. A limiting rod 520 is slidably sleeved on the side wall of the square rod 506. Limiting plates 521 are fixedly connected to both ends of the limiting rod 520. A second spring 522 is fixedly connected between the limiting plate 521 and the square rod 506. The limiting plate 521 is slidably connected with the side wall of the moving cylinder 504;

[0037] First, during the process of the moving cylinder 504 driving the shaking plate 503, the fixed plate 507 and the square rod 506 to move, when the shaking plate 503 abuts against the rape leaves, during the continuous movement of the shaking plate 503, when the shaking plate 503 gradually moves towards the direction close to the rape stem, the shaking plate 503 will gradually be blocked by the rape stem, which will cause the whole of the shaking plate 503, the fixed plate 507 and the square rod 506 to move leftward relative to the moving cylinder 504 (based on Figure 7Based on the direction of, the fixed plate 507 drives the second rack 532 to move leftward through the fixed rod 523. The second rack 532 drives the gear cylinder 531 to rotate clockwise. The gear cylinder 531 drives the third rack 533 to move downward. The third rack 533 drives the positioning plate 534 to move downward. Under the action of the inclined groove 528, the downward-moving positioning plate 534 drives the positioning rod 526 and the inclined plate 529 to move leftward and downward. The inclined plate 529 drives the control plate 525 to move leftward. The control plate 525 enters between the adjacent rotating rods 516. During this process, the reciprocating lead screw 501 always drives the rotating plate 514 and the rotating rod 516 to rotate. When the control plate 525 enters between the adjacent rotating rods 516 and the rotating rod 516 abuts against the control plate 525, the rotating rod 516 drives the control plate 525 to move relative to the moving cylinder 504. The control plate 525 drives the fixed frame 515 to move. The fixed frame 515 drives the hydraulic rod 518 to move through the sliding plate 517. The hydraulic rod 518 drives the square rod 506 to move. The square rod 506 drives the fixed plate 507 and the shaking plate 503 to move. The square rod 506 compresses or stretches the second spring 522. When the control plate 525 is disconnected from the rotating rod 516, under the action of the second spring 522, the whole square rod 506 returns to the middle position inside the moving cylinder 504 again. Eventually, during the rotation of the rotating plate 514 and the rotating rod 516, the shaking plate 503 moves back and forth. The shaking plate 503 abuts against the rape leaves, which not only compresses the rape leaves to make the rape leaves move, but also the shaking shaking plate 503 makes the rape leaves move slightly, preventing the obstacles accidentally accumulated outside the rape leaves from affecting the later detection effect during the detection of the rape leaves, thereby ensuring the accuracy of the detection results. And the greater the degree of obstruction of the rape leaves to the shaking plate 503, the greater the distance the control plate 525 moves leftward and downward, the shorter the contact time between the control plate 525 and the rotating rod 516, and the smaller the shaking amplitude of the shaking plate 503, reducing the damage to the rape leaves.

[0038] Such as Figure 9 , a second gear 6 is also fixedly sleeved on the outer side of the reciprocating lead screw 501. Two groups of transmission rods 7 are rotatably connected to the outer side of the bracket 1. A third gear 8 is fixedly sleeved on the outer sides of the two groups of transmission rods 7. The third gear 8 meshes with the second gear 6. A plurality of groups of bearings are rotatably installed on the side wall of the bracket 1. A plurality of wheels 4 are fixedly installed on the outer sides of the plurality of groups of bearings. A pulley assembly 9 is sleeved between the transmission rod 7 and the bearing. When the double-shaft motor 2 is started, the double-shaft motor 2 drives the reciprocating lead screw 501 to rotate. The reciprocating lead screw 501 drives the second gear 6 and the rotating plate 514 to rotate. The second gear 6 drives the transmission rod 7 to rotate through the third gear 8. The transmission rod 7 drives the wheel 4 and the bearing to rotate through the pulley assembly 9. The whole device is placed on the field to make the device move along the corresponding track and perform corresponding detection operations on the rape leaves.

[0039] In the present invention, when it is necessary to perform a disease detection operation on rapeseed leaves, the biaxial motor 2 is started. The biaxial motor 2 drives the reciprocating lead screw 501 to rotate. The reciprocating lead screw 501 drives the second gear 6 and the rotating plate 514 to rotate. The second gear 6 drives the transmission rod 7 to rotate through the third gear 8. The transmission rod 7 drives the wheels 4 and the bearings to rotate through the pulley assembly 9. The whole device is placed on the field, and the device moves along the corresponding track. Since the slider 502 and the bracket 1 are slidably connected, the rotating reciprocating lead screw 501 will drive the slider 502 to move back and forth left and right relative to the bracket 1. The slider 502 drives the moving cylinder 504 to move back and forth left and right through the slide rod 505. The moving cylinder 504 drives the fixed plate 507 to move back and forth left and right through the first spring 508. The fixed plate 507 drives the shaking plate 503 to move back and forth left and right. The shaking plate 503 abuts against the rapeseed leaves and drives the rapeseed leaves to shake, thereby improving the shooting effect of the camera 3 on the rapeseed leaves. It is not necessary for the staff to touch the rapeseed leaves by hand, and the degree of intelligence is relatively high;

[0040] During the process of the moving cylinder 504 moving back and forth left and right, the moving cylinder 504 drives the first rack 513 to move back and forth left and right through the connecting rod. The first rack 513 drives the first gear 511 and the rotating cylinder 510 to rotate back and forth around the fixed gantry rod 509. The rotating cylinder 510 drives the rotating gantry rod 512 and the camera 3 to rotate back and forth around the rotating cylinder 510, improving the shooting range of the camera 3, and thus can better complete the shooting and detection operation of the rapeseed leaves, ensuring the detection effect;

[0041] When the shaking plate 503 abuts against the rapeseed leaves, during the continuous movement of the shaking plate 503, when the shaking plate 503 gradually moves towards the direction close to the rapeseed stem, the shaking plate 503 will be obstructed by the rapeseed, preventing the shaking plate 503 from following the movement of the moving cylinder 504. The first spring 508 is compressed. The shaking plate 503, the fixed plate 507 and the square rod 506 as a whole move left relative to the moving cylinder 504. When the button 519 enters the moving cylinder 504, the button 519 abuts against the moving cylinder 504 and is pressed by the moving cylinder 504. At this time, the hydraulic rod 518 is started, and the shaking plate 503, the square rod 506 and the fixed rod 523 as a whole will move left and disconnect from the rapeseed leaves. When the control time of the button 519 ends, at this time the moving cylinder 504 is in the state of moving left, and the shaking plate 503, the square rod 506 and the fixed rod 523 as a whole return to their original positions relative to the moving cylinder 504 under the action of the first spring 508. Finally, when the shaking plate 503 abuts against the rapeseed leaves and drives the rapeseed leaves to move, if the resistance of the rapeseed leaves is relatively large, it means that the shaking plate 503 has abutted against the rapeseed stem and leaves. At this time, the shaking plate 503 quickly disconnects from the rapeseed and will not cause damage to the rapeseed leaves due to continuously applying force to the rapeseed leaves. The degree of intelligence is relatively high;

[0042] During the process of the moving cylinder 504 driving the shaking plate 503, the fixing plate 507 and the square rod 506 to move, when the shaking plate 503 abuts against the rape leaves, during the continuous movement of the shaking plate 503, when the shaking plate 503 gradually moves towards the direction close to the rape stem, the assembly of the shaking plate 503 will be hindered by the rape, which will cause the whole of the shaking plate 503, the fixing plate 507 and the square rod 506 to move leftward relative to the moving cylinder 504 (based on Figure 7 the direction of...), the fixing plate 507 drives the second rack 532 to move leftward through the fixing rod 523, the second rack 532 drives the gear cylinder 531 to rotate clockwise, the gear cylinder 531 drives the third rack 533 to move downward, the third rack 533 drives the positioning plate 534 to move downward, under the action of the inclined groove 528, the downward moving positioning plate 534 will drive the positioning rod 526 and the inclined plate 529 to move leftward and downward, the inclined plate 529 drives the control plate 525 to move leftward, and the control plate 525 enters between the adjacent rotating rods 516. During this process, the reciprocating lead screw 501 always drives the rotating plate 514 and the rotating rod 516 to rotate. When the control plate 525 enters between the adjacent rotating rods 516, when the rotating rod 516 abuts against the control plate 525, the rotating rod 516 will drive the control plate 525 to move relative to the moving cylinder 504, the control plate 525 drives the fixed frame 515 to move, the fixed frame 515 drives the first hydraulic rod 518 to move through the sliding plate 517, the first hydraulic rod 518 drives the square rod 506 to move, the square rod 506 drives the fixing plate 507 and the shaking plate 503 to move, and the square rod 506 compresses or stretches the second spring 522. When the control plate 525 is disconnected from the rotating rod 516, under the action of the second spring 522, the whole of the square rod 506 returns to the middle position inside the moving cylinder 504 again. Finally, during the rotation of the rotating plate 514 and the rotating rod 516, the shaking plate 503 moves back and forth, and the shaking plate 503 abuts against the rape leaves, which will not only compress the rape leaves and make the rape leaves move, but also the shaking shaking plate 503 will make the rape leaves move slightly, preventing the obstacles accidentally accumulated outside the rape leaves from affecting the later detection effect during the detection of the rape leaves, thereby ensuring the accuracy of the detection result. And as the degree of obstruction of the rape leaves to the shaking plate 503 is greater, the distance that the control plate 525 moves leftward and downward is greater, the contact time between the control plate 525 and the rotating rod 516 is shorter, and the shaking amplitude of the shaking plate 503 is smaller, reducing the damage to the rape leaves.
