Description

Technical Field

[0001] The present invention belongs to the technical field of spraying effect detection, and specifically relates to a large-flow spraying droplet distribution system for plant protection. Background Art

[0002] When irrigating crops, large-flow spraying droplets are mostly used for irrigation. It has a large flow rate and high water pressure, can atomize water into fine droplets, and evenly spray them on farmland or plants. It has the characteristics of large coverage area and high droplet density, which can improve irrigation efficiency and save water resources at the same time.

[0003] However, the above-mentioned technology often has the following defects: When testing the droplet coverage distribution at various positions within the spraying range, due to the wide irrigation range of droplets, it leads to a large workload and time-consuming for staff to collect droplets. Therefore, there is an urgent need for a large-flow spraying droplet distribution test device to automatically obtain the droplet deposition amount distribution at each preset point by using a distribution test control system, so as to reduce the manual labor and improve the test automation rate.

[0004] Therefore, the present invention provides a large-flow spraying droplet distribution system for plant protection. Summary of the Invention

[0005] In order to make up for the deficiencies of the prior art and solve at least one of the technical problems proposed in the background art.

[0006] The technical solution adopted by the present invention to solve its technical problems is as follows: A large-flow spraying droplet distribution system for plant protection of the present invention includes a guide rail, a bracket is installed on the surface of the guide rail, the bracket is connected to the guide rail through a chain drive system, a waterproof cover is fixedly connected to the surface of the bracket, a control mechanism is fixedly connected to the end of the guide rail, a flipping mechanism is arranged on the surface of the bracket, a collection port is arranged on the surface of the waterproof cover, the other end of the collection port penetrates through the waterproof cover and is connected to a diversion cover, a group of suspension rods are fixedly connected to one side of the waterproof cover, the end of the suspension rod is rotatably connected to a liquid accumulation tank through a round shaft, the liquid accumulation tank and the round shaft are in clearance fit, a pressure rod is fixedly connected to the surface of the liquid accumulation tank, a weighing scale is fixedly connected to the surface of the bracket, the surface of the weighing scale is in contact with the pressure rod, and the connection position between the suspension rod and the liquid accumulation tank is located at a position to the right of the center of the liquid accumulation tank;

[0007] During operation, driven by the instructions of the control system, the chain drives the entire device to move. After moving it to the position to be measured, the control mechanism records the data of the weighing scale at this time. Then, the collection port collects the nearby droplets, and at the same time, the collected droplets are transported to the liquid accumulation tank through the diversion cover. The water in the liquid accumulation tank increases. Since the connection position between the hanging rod and the liquid accumulation tank is located to the right of the center of the liquid accumulation tank and there is a gap between the circular shaft and the hanging rod, the gravity generated by the liquid accumulation tank is transmitted to the surface of the weighing scale through the pressure rod. At this time, the control mechanism continuously records the data generated by the weighing scale. When the preset time is reached, the recording stops. At this time, by comparing the weight at the first recording with the weight at the last recording, the droplet distribution in this area can be known, and then the spraying amount can be adjusted. Then, through the flipping mechanism, after collecting a certain amount of water, the water is poured out. Through the guide rail, the droplet coverage at each point within the spraying range can be measured point by point according to the preset points, thereby reducing the manual labor and improving the test automation rate.

[0008] Preferably, a motor one is fixedly connected to the surface of the waterproof cover. The output end of the motor one is fixedly connected to a rotating rod one. The end of the rotating rod one is rotatably connected to a rotating shaft one. The other end of the rotating shaft is fixedly connected to a sliding cover plate. A fixed shaft is fixedly connected to the surface of the cover plate. A slide rail one is fixedly connected to the surface of the waterproof cover. The end of the fixed rod slides in the slide rail one. During operation, the control mechanism controls the motor one to drive the rotating rod one to rotate. At the same time, the rotating rod one moves the sliding cover plate above the collection port through the rotating shaft one to block the collection port. The sliding cover plate can accurately control the droplet collection amount, and after the device moves to the preset position, the sliding cover plate can be opened for collection, thereby avoiding excessive accumulation of redundant water in the liquid accumulation tank and resulting in a decrease in the measurement efficiency.

[0009] Preferably, the motor one is a bidirectional coaxial motor, and two sliding cover plates are provided. A pair of the sliding cover plates are symmetrically distributed with respect to the central axis of the collection port. During operation, the bidirectional coaxial motor, also called a coaxial dual-propeller motor, is such that the same output shaft can drive two rotating rod ones to rotate in opposite directions, changing the single-opening of the sliding cover plate to double-opening, improving the opening and closing efficiency of the sliding cover plate, and thus can more accurately control the droplet collection amount.

[0010] Preferably, the flipping mechanism includes a second motor, which is fixedly connected to the surface of the bracket. A support rod is fixedly connected to the surface of the bracket. The output shaft of the second motor penetrates through the support rod and is rotatably connected. A second rotating rod is fixedly connected to the surface of the output shaft of the second motor. A sliding shaft is fixedly connected to the end of the second rotating rod. A connecting rod is fixedly connected to the surface of the liquid accumulation tank. The connecting rod is in an "L" shape. A second sliding rail is fixedly connected to the short arm end of the connecting rod. A guiding groove is formed on the surface of the second sliding rail. The sliding shaft is slidably connected in the guiding groove. During operation, when the water in the liquid accumulation tank reaches the preset weight of the weighing scale, the control mechanism controls the second motor to start, so that the output shaft of the second motor drives the second rotating rod to rotate. At this time, the sliding shaft fixedly connected to the surface of the second rotating rod will press down the second sliding rail, causing the liquid accumulation tank to reverse and pour out the water in the liquid accumulation tank for repeated collection, further improving the automation degree of the device during use.

[0011] Preferably, the bottom surface of the liquid accumulation tank is made of an elastic material. A cross beam is fixedly connected to the surface of the bracket. A base is fixedly connected to the surface of the cross beam. A vertical rod is fixedly connected to the surface of the base. A chute is formed on the surface of the vertical rod. A slider is slidably connected in the vertical rod. The slider is in a "T" shape. The protruding part of the slider is slidably connected in the chute. A cavity is formed in the base, and a reel is rotatably connected in the cavity through a torsion spring. A connecting rope is fixedly connected to the surface of the reel. The other end of the connecting rope penetrates through the side wall of the inner cavity and is fixedly connected to the slider. Both ends of the reel penetrate through the side wall of the cavity and are rotatably connected, and a connecting shaft is fixedly connected to the end. The other end of the connecting shaft is connected to an impact ball through a spring.

[0012] During operation, when the liquid accumulation tank rotates, it will drive the block on the bottom surface to rotate. When the block rotates to the position of the slider, it will drive the slider to slide in the vertical rod, and at the same time, it will pull the reel to rotate through the connecting rope. When the reel rotates, the torsion spring will rotate and store energy. When the reel rotates, it will drive the connecting shaft to rotate, so that the connecting shaft drives the impact ball to impact the bottom surface of the liquid accumulation tank, causing it to vibrate and shake off the water in the liquid accumulation tank, further improving the liquid drainage efficiency when the liquid accumulation tank reverses.

[0013] Preferably, the protruding part of the slider is a limiting block, and the limiting block is slidably connected in the slider through an elastic sheet. A through groove is formed on the surface of the vertical rod. A block is rotatably connected to the outer wall of the liquid accumulation tank. The surface of the block is an arc surface, and the rotation angle of the block is 90°. During operation, when the block drives the limiting block to move to the extreme position of the vertical rod, the arc surface on the surface of the block will squeeze the limiting block, causing it to move in the slider and at the same time squeezing the elastic sheet to generate an elastic force. Then the liquid accumulation tank continues to rotate. When the limiting block passes through the through groove, the limiting block disengages from the slider. At this time, the elastic sheet drives the limiting block to reset, and at the same time the torsion spring resets, driving the connecting shaft to continue to rotate, so that the impact ball continuously knocks on the liquid accumulation tank, thereby improving the impact effect of the impact ball.

[0014] Preferably, the bottom of the liquid accumulation tank is arc-shaped, and the vertical rod is matched with the bottom surface of the liquid accumulation tank; during operation, the bottom surface of the liquid accumulation tank is arc-shaped, which can promote its liquid drainage effect and avoid dead corners and residual water.

[0015] Preferably, a rubber pad is fixedly sleeved on the surface of the impact ball; during operation, the rubber pad can play a protective role to avoid damaging the impact ball and the liquid accumulation tank due to long-term impact.

[0016] The beneficial effects of the present invention are as follows:

[0017] 1. For the large-flow spraying droplet distribution system for plant protection of the present invention, the control mechanism continuously records the data generated by the weighing scale. When the preset time is reached, the recording stops. At this time, by comparing the weight at the first recording with the weight at the last recording, the droplet distribution situation in this area can be known, and then the spraying amount can be adjusted. Then, through the flipping mechanism, after collecting a certain amount of water, the water is poured out. Through the guide rail, the droplet coverage situation at each point within the spraying range can be measured point by point according to the preset points, thereby reducing the manual labor amount and improving the test automation rate.

[0018] 2. For the large-flow spraying droplet distribution system for plant protection of the present invention, when the liquid accumulation tank rotates and drives the dial block to rotate to the position of the slider, the slider is squeezed to slide in the vertical rod. At the same time, the connecting rope is pulled to drive the reel to rotate. While the reel rotates, the torsion spring rotates and stores energy. While the reel rotates, the connecting shaft is driven to rotate, so that the connecting shaft drives the impact ball to impact the bottom surface of the liquid accumulation tank, causing it to vibrate and shaking off the water in the liquid accumulation tank, further improving the liquid drainage efficiency when the liquid accumulation tank rotates in reverse.

Detailed implementation manners

[0029] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0030] Embodiment 1: As shown in Figures 1 to 4 , a large-flow spraying droplet distribution system for plant protection described in an embodiment of the present invention includes a guide rail 1, a bracket 5 is installed on the surface of the guide rail 1, the bracket 5 is connected to the guide rail 1 through a chain drive system, a waterproof cover 6 is fixedly connected to the surface of the bracket 5, a control mechanism 2 is fixedly connected to the end of the guide rail 1, a flipping mechanism 4 is arranged on the surface of the bracket 5, a collection port 8 is arranged on the surface of the waterproof cover 6, the other end of the collection port 8 penetrates through the waterproof cover 6 and is connected to a diversion cover 18 in a through manner, a group of hanging rods 14 are fixedly connected to one side of the waterproof cover 6, the end of the hanging rod 14 is rotationally connected to a liquid accumulation tank 3 through a round shaft, the liquid accumulation tank 3 and the round shaft are in clearance fit, a pressing rod 12 is fixedly connected to the surface of the liquid accumulation tank 3, a weighing scale 13 is fixedly connected to the surface of the bracket 5, the surface of the weighing scale 13 is in contact with the pressing rod 12, and the connection position of the hanging rod 14 and the liquid accumulation tank 3 is located at a position to the right of the center of the liquid accumulation tank 3;

[0031] During operation, driven by the instructions of the control system, the chain drives the entire device to move. After moving it to the position to be measured, the control mechanism 2 records the data of the weighing scale 13 at this time. Then, the collection port 8 collects the nearby droplets, and at the same time, the collected droplets are transported to the liquid accumulation tank 3 through the diversion cover 18. The water in the liquid accumulation tank 3 increases. Since the connection position between the suspension rod 14 and the liquid accumulation tank 3 is located to the right of the center of the liquid accumulation tank 3 and there is a gap between the circular shaft and the suspension rod 14, the gravity generated by the liquid accumulation tank 3 is evenly transmitted to the surface of the weighing scale 13 through the pressure rod 12. At this time, the control mechanism 2 continuously records the data generated by the weighing scale 13. When the preset time is reached, the recording stops. At this time, by comparing the weight at the first recording with the weight at the last recording, the droplet distribution in this area can be known, and then the spraying amount can be adjusted. Then, through the flipping mechanism 4, after collecting a certain amount of water, the water is poured out. Through the guide rail 1, the droplet coverage at each point within the spraying range can be measured point by point according to the preset points, thereby reducing the manual labor and improving the test automation rate.

[0032] A motor 9 is fixedly connected to the surface of the waterproof cover 6. The output end of the motor 9 is fixedly connected to a rotating rod 11. The end of the rotating rod 11 is rotatably connected to a rotating shaft 19. The other end of the rotating shaft is fixedly connected to a sliding cover plate 7. A fixed shaft 20 is fixedly connected to the surface of the cover plate. A slide rail 10 is fixedly connected to the surface of the waterproof cover 6. The end of the fixed rod slides in the slide rail 10; during operation, the control mechanism 2 controls the motor 9 to drive the rotating rod 11 to rotate. At the same time, the rotating rod 11 moves the sliding cover plate 7 above the collection port 8 through the rotating shaft 19 to block the collection port 8. The sliding cover plate 7 can accurately control the droplet collection amount, and can wait until the device moves to the preset point, and then open the sliding cover plate 7 for collection, thereby avoiding excessive accumulation of redundant water in the liquid accumulation tank 3 and resulting in a decrease in the measurement efficiency.

[0033] The motor 9 is a bidirectional coaxial motor. There are two sliding cover plates 7. A pair of the sliding cover plates 7 are symmetrically distributed with respect to the central axis of the collection port 8; during operation, the bidirectional coaxial motor is also called a coaxial dual-propeller motor. The same output shaft can drive two rotating rods 11 to rotate in opposite directions, so that the sliding cover plate 7 is changed from single-opening to double-opening, improving the opening and closing efficiency of the sliding cover plate 7, and thus can more accurately control the droplet collection amount.

[0034] The turning mechanism 4 includes a second motor 25 which is fixedly connected to the surface of the bracket 5. A support rod 17 is fixedly connected to the surface of the bracket 5. The output shaft of the second motor 25 passes through the support rod 17 and is rotatably connected. A second rotating rod 15 is fixedly connected to the surface of the output shaft of the second motor 25. A sliding shaft 26 is fixedly connected to the end of the second rotating rod 15. A connecting rod 22 is fixedly connected to the surface of the liquid collecting tank 3. The connecting rod 22 is in an "L" shape. A second slide rail 21 is fixedly connected to the short arm end of the connecting rod 22. A guiding groove 24 is formed on the surface of the second slide rail 21. The sliding shaft 26 is slidably connected in the guiding groove 24. During operation, when the water in the liquid collecting tank 3 reaches the preset weight of the weighing scale 13, the control mechanism 2 controls the second motor 25 to start, so that the output shaft of the second motor 25 drives the second rotating rod 15 to rotate. At this time, the sliding shaft 26 fixedly connected to the surface of the second rotating rod 15 will press down the second slide rail 21, causing the liquid collecting tank 3 to reverse and pour out the water in the liquid collecting tank 3 for repeated collection, further improving the automation degree during the use of the device.

[0035] Embodiment 2: As Figures 5 to 8 shown, compared with Embodiment 1, another implementation manner of the present invention is: the bottom surface of the liquid collecting tank 3 is made of an elastic material. A cross beam 16 is fixedly connected to the surface of the bracket 5. A base 32 is fixedly connected to the surface of the cross beam 16. A vertical rod 36 is fixedly connected to the surface of the base 32. A chute 28 is formed on the surface of the vertical rod 36. A slider 33 is slidably connected in the vertical rod 36. The slider 33 is in a "T" shape. The protruding part of the slider 33 is slidably connected in the chute 28. A cavity is formed in the base 32, and a reel 27 is rotatably connected in the cavity through a torsion spring. A connecting rope 29 is fixedly connected to the surface of the reel 27. The other end of the connecting rope 29 passes through the inner cavity side wall and is fixedly connected to the slider 33. Both ends of the reel 27 pass through the cavity side wall and are rotatably connected, and a connecting shaft 31 is fixedly connected to the end. The other end of the connecting shaft 31 is connected to an impact ball 30 through a spring;

[0036] During operation, when the liquid collecting tank 3 rotates, it will drive the bottom surface dial 37 to rotate. When the dial 37 rotates to the position of the slider 33, it will drive the slider 33 to slide in the vertical rod 36. At the same time, it will pull the reel 27 to rotate through the connecting rope 29. When the reel 27 rotates, the torsion spring will rotate and store energy. When the reel 27 rotates, it will drive the connecting shaft 31 to rotate, so that the connecting shaft 31 drives the impact ball 30 to impact the bottom surface of the liquid collecting tank 3, generating vibration and shaking off the water in the liquid collecting tank 3, further improving the liquid drainage efficiency when the liquid collecting tank 3 reverses.

[0037] The convex part of the slider 33 is the limit block 34. The limit block 34 is slidably connected in the slider 33 through an elastic piece. A through groove 23 is formed on the surface of the vertical rod 36. A dial block 37 is rotatably connected to the outer wall of the liquid accumulation tank 3. The surface of the dial block 37 is an arc surface, and the rotation angle of the dial block 37 is 90°. During operation, when the dial block 37 drives the limit block 34 to move to the extreme position of the vertical rod 36, the arc surface on the surface of the dial block 37 will squeeze the limit block 34, causing it to move within the slider 33, and at the same time, generating an elastic force by squeezing the elastic piece. Then the liquid accumulation tank 3 continues to rotate. When the limit block 34 passes through the through groove 23, the limit block 34 disengages from the slider 33. At this time, the elastic piece drives the limit block 34 to reset, and at the same time, the torsion spring resets, driving the connecting shaft 31 to continue rotating, so that the impact ball continuously strikes the liquid accumulation tank 3, thereby improving the impact effect of the impact ball 30.

[0038] The bottom of the liquid accumulation tank 3 is arc-shaped, and the vertical rod 36 is matched with the bottom surface of the liquid accumulation tank 3. During operation, the bottom surface of the liquid accumulation tank 3 being arc-shaped can promote its liquid drainage effect and avoid dead corners where moisture remains.

[0039] A rubber pad is fixedly sleeved on the surface of the impact ball. During operation, the rubber pad can play a protective role to avoid damaging the impact ball 30 and the liquid accumulation tank 3 due to long-term impacts.

[0040] Working principle: Driven by the control system command, the chain drives the whole device to move. After moving it to the position to be measured, the control mechanism 2 records the data of the weighing scale 13 at this time. Then the collection port 8 collects the nearby fog droplets, and at the same time conveys the collected fog droplets to the liquid accumulation tank 3 through the diversion cover 18. The water in the liquid accumulation tank 3 increases. Because the connection position between the suspension rod 14 and the liquid accumulation tank 3 is located to the right of the center of the liquid accumulation tank 3 and there is a gap between the round shaft and the suspension rod 14, the gravity generated by the liquid accumulation tank 3 is evenly transmitted to the surface of the weighing scale 13 through the pressure rod 12. At this time, the control mechanism 2 continuously records the data generated by the weighing scale 13. When the preset time is reached, the recording stops. At this time, by comparing the weight at the first recording with the weight at the last recording, the fog droplet distribution in this area can be known, and then the spraying amount can be adjusted. Then through the flipping mechanism 4, after collecting a certain amount of water, the water is poured out. Through the guide rail 1, the fog droplet coverage at each point within the spraying range can be measured point by point according to the preset points, thereby reducing the manual labor and improving the test automation rate.

[0041] The control mechanism 2 controls the first motor 9 to drive the first rotating rod 11 to rotate. At the same time, the first rotating rod 11 moves the sliding cover plate 7 above the collection port 8 through the first rotating shaft 19 to block the collection port 8. The sliding cover plate 7 can accurately control the amount of fog droplets collected. And after the device moves to the preset position, the sliding cover plate 7 can be opened to collect, thus avoiding excessive accumulation of redundant water in the liquid accumulation tank 3, which may lead to a decrease in the measurement efficiency. The bidirectional coaxial motor, also called the coaxial double-paddle motor, has the same output shaft that can drive two first rotating rods 11 to rotate in opposite directions, changing the single-opening of the sliding cover plate 7 to double-opening, improving the opening and closing efficiency of the sliding cover plate 7, and thus can more accurately control the amount of fog droplets collected;

[0042] When the water in the liquid accumulation tank 3 reaches the preset weight of the weighing scale 13, the control mechanism 2 controls the second motor 25 to start, so that the output shaft of the second motor 25 drives the second rotating rod 15 to rotate. At this time, the sliding shaft 26 fixedly connected to the surface of the second rotating rod 15 will press down the second slide rail 21, causing the liquid accumulation tank 3 to reverse and pour out the water in the liquid accumulation tank 3 for repeated collection, further improving the automation degree during the use of the device. When the liquid accumulation tank 3 rotates, it will drive the bottom block 37 to rotate. When the block 37 rotates to the position of the slider 33, it will drive the slider 33 to slide in the vertical rod 36, and at the same time, it will pull the reel 27 to rotate through the connecting rope 29. When the reel 27 rotates, the torsion spring will rotate and store energy. When the reel 27 rotates, it will drive the connecting shaft 31 to rotate, so that the connecting shaft 31 drives the impact ball 30 to impact the bottom surface of the liquid accumulation tank 3, generating vibrations to shake off the water in the liquid accumulation tank 3, further improving the drainage efficiency when the liquid accumulation tank 3 reverses;

[0043] When the block 37 drives the limit block 34 to move to the extreme position of the vertical rod 36, the arc surface of the block 37 will squeeze the limit block 34, causing it to move within the slider 33 and simultaneously generating elastic force by squeezing the elastic piece. Then the liquid accumulation tank 3 continues to rotate. When the limit block 34 passes through the through slot 23, the limit block 34 disengages from the slider 33. At this time, the elastic piece drives the limit block 34 to reset, and at the same time, the torsion spring resets, driving the connecting shaft 31 to continue rotating, causing the impact ball to continuously strike the liquid accumulation tank 3, thereby improving the impact effect of the impact ball 30. The bottom surface of the liquid accumulation tank 3 is arc-shaped, which can promote its drainage effect and avoid dead corners with residual water.
