[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0025] Reference Figure 1-4 A plant protection machine with adjustable row spacing includes a plant protection machine body 1, four supporting legs 11 are fixedly connected to the bottom of the plant protection machine body 1, the inner sides of the four supporting legs 11 are rotatably connected to wheels 12, the top of the plant protection machine body 1 is fixedly connected to a water tank 2, one side of the plant protection machine body 1 is fixedly connected to an installation box 3 with five nozzles 46 arranged on it, a spraying mechanism 4 is arranged between the installation box 3, the plant protection machine body 1, the water tank 2 and the five nozzles 46, a synchronous row spacing adjustment mechanism 5 is arranged between the installation box 3 and the five nozzles 46, and a controller 6 is fixedly connected to the front side of the installation box 3.
[0026] Specifically, a plurality of pedals 13 are fixedly connected to the front side of the right front support leg 11, and the pedals 13 facilitate the driver to get into the cab.
[0027] Specifically, refer to Figure 1 and Figure 4 The spraying mechanism 4 includes a water pump 41 fixedly connected to the top of the plant protection body 1 and a main pipe 42 fixedly connected to the top of the installation box 3. The water pump 41 is connected to the bottom of one side of the water tank 2, and the water outlet end of the water pump 41 is connected to one side of the main pipe 42. The other side of the main pipe 42 is fixedly connected with five water outlet pipes 45, and the five nozzles 46 are respectively connected to the bottom ends of the corresponding water outlet pipes 45. The upper part of the water outlet pipe 45 is a hose setting, which does not hinder the movement and adjustment of the fixed sleeve 505, and the lower part of the water outlet pipe 45 is a hard pipe, which is conducive to the fixed sleeve being arranged in the fixed sleeve 505, so that it can drive the water outlet pipe 45 to move and adjust.
[0028] With the above solution, the liquid medicine or clean water in the water tank 2 can be pumped into the water supply pipe 43 and the main pipe 42 by the water pump 41, and finally diverted to the five outlet pipes 45 and the nozzles 46, and finally the crops are sprayed with medicine or water.
[0029] Specifically, a water supply pipe 43 is fixedly connected between the water outlet end of the water pump 41 and one side of the main pipeline 42 , which facilitates the communication between the water pump 41 and the main pipeline 42 .
[0030] Specifically, the top of the installation box 3 is fixedly connected to two fixing seats 44 , and the main pipeline 42 is fixedly connected to the top of the two fixing seats 44 , which is conducive to fixing the main pipeline 42 .
[0031] Specifically, a water inlet is provided on the top of the water tank 2, and an adding pipe is fixedly connected to the water inlet to facilitate the adjustment of clean water and liquid medicine.
[0032] Specifically, refer to Figure 1-3The synchronous line spacing adjustment mechanism 5 includes a fixed rod 502 and four movable rods 503, and a servo motor 501 fixedly connected to the front side of the installation box 3. A double-headed screw rod 508 is fixedly connected to the output shaft of the servo motor 501. The outer thread sleeve of the double-headed screw rod 508 is provided with two drive plates 509. The fixed rod 502 is fixedly connected to the center of one side of the installation box 3. The four movable rods 503 are slidably set on the installation box 3. One side of the four movable rods 503 is fixedly connected to a connecting rod 1 507. The center of the inner wall of one side of the installation box 3 is fixedly connected to a connecting rod 2 506. Rod 2 506 and the top of the four connecting rods 507 are rotatably connected to the same telescopic frame 510, two driving plates 509 are fixedly connected to one end of the corresponding two connecting rods 507, a fixed rod 502 and one end of the four movable rods 503 are fixedly connected to a fixed sleeve 505, five water outlet pipes 45 are respectively fixedly sleeved in the corresponding fixed sleeve 505, and the front side of the rearmost connecting rod 507 is fixedly connected to a distance sensor 511 used to measure the distance between the two connecting rods 507, and the distance sensor 511 and the servo motor 501 are electrically connected to the controller 6.
[0033] The above scheme is adopted: according to the different row spacings of the crops, the double-headed screw 508 is driven to rotate by the servo motor 501, and the double-headed screw 508 drives the two driving plates 509 to move closer to or away from each other. Since the fixed sleeve 505, the fixed rod 502 and the connecting rod 2 506 at the center position are fixedly set, the driving plates 509 set on the front and rear sides can synchronously drive the two connecting rods 1 507 on the outside to move closer to or away from each other. Under the transmission of the telescopic frame 510 (similar to the telescopic frame in the hydraulic lifting platform), the four connecting rods 1 507 and the movable rod 506 are synchronously driven. 03 and the fixed sleeve 505 are synchronously moved closer to each other or away from each other, and the row spacing between the nozzles 46 can be adjusted synchronously to ensure the consistency of the row spacing between the nozzles 46, and prevent the row spacing between the nozzles 46 from affecting the spraying of crops due to the adjustment. The distance sensor 511 can be used to measure the distance between the two connecting rods 507, and then the distance between the nozzles 46 can be measured. When the specified requirements are met, the distance sensor 511 sends a signal to the controller 6, and the controller 6 turns off the servo motor 501, and then the row spacing between the nozzles 46 can be accurately adjusted synchronously.
[0034] Specifically, two rectangular openings 504 are opened on one side of the installation box 3, and the four movable rods 503 are slidably mounted in the corresponding rectangular openings 504 respectively. The two driving plates 509 and the four connecting rods 507 are all slidably arranged in the installation box 3, which is conducive to guiding the movable rods 503, the driving plates 509 and the connecting rods 507, making their movement more stable and smooth.
[0035] In the present invention, when in use, the pedal 13 is used to facilitate the driver to get into the cab. When the plant protection machine body 1 is traveling, the liquid medicine or clean water in the water tank 2 can be pumped into the water supply pipe 43 and the main pipe 42 through the water pump 41, and finally diverted to the five outlet pipes 45 and the nozzle 46, and finally the crops are sprayed with medicine or water. According to the different row spacings of the crops, the servo motor 501 is started, and the servo motor 501 drives the rotation of the double-headed screw rod 508, and the double-headed screw rod 508 drives the two drive plates 509 to move closer to or away from each other. Because the fixed sleeve 505, the fixed rod 502 and the connecting rod 2 506 at the center position are fixed, the drive plates 509 set on the front and rear sides can synchronously drive the two outer connecting rods 1 507 to move closer to and away from each other. They move away from each other, and under the transmission of the telescopic frame 510 (similar to the telescopic frame in the hydraulic lifting platform), the four connecting rods 507, the movable rod 503 and the fixed sleeve 505 are synchronously driven to move closer to each other or move away from each other, so that the row spacing between the nozzles 46 can be adjusted synchronously to ensure the consistency of the row spacing between the nozzles 46, and prevent the row spacing between the nozzles 46 from affecting the spraying of crops after adjustment. The distance sensor 511 can be used to measure the distance between the two connecting rods 507, and then the distance between the nozzles 46 can be measured. When the specified requirements are met, the distance sensor 511 sends a signal to the controller 6, and the controller 6 turns off the servo motor 501, so that the row spacing between the nozzles 46 can be accurately adjusted synchronously.
