In the field of agricultural plant protection, the spray uniformity of plant protection machinery is crucial to the protection effect of crops. Accurate and uniform spraying can ensure that pesticides, fertilizers and other materials are evenly covered on the surface of crops, improve the effect of pest control and disease prevention and control and the utilization rate of fertilizers, thereby promoting the healthy growth of crops.

[0003] In the prior art, when testing the spray uniformity of a plant protection machine nozzle before it is put into use, evenly arranged measuring cups are mainly used to collect the mist water sprayed by the machine nozzle.

[0024] A support frame 101 is fixedly installed at the bottom of the funnel-shaped table top 103, a controller 102 is installed between the inner surface walls of the support frame 101 near the left side, and a water tank 108 is fixedly connected to the top of the support frame 101 near the right side. The support frame 101 is mainly used to support the device off the ground. The controller 102 is a PLC control host, which can analyze and process the received electrical signals and transmit them to an external display device. The water tank 108 is used to store water needed for spraying.

[0025] A motor base 202 is fixedly connected to a position near the bottom between the inner surface walls of the connecting column 201, a servo motor 301 is fixedly installed on the top of the motor base 202, a square rotating block 302 is fixedly connected to the output end of the servo motor 301, the square rotating block 302 is rotatably connected to the top center of the platform 203, and sliding grooves 303 are provided on the four side surfaces of the square rotating block 302, a slider 304 is slidably connected between the inner surface walls of the sliding groove 303, a spring 306 is fixedly connected between the top of the slider 304 and the inner top of the sliding groove 303, a connecting arm 305 is fixedly connected to the outer surface of the slider 304 away from the square rotating block 302, a wedge block 307 is fixedly connected to the outer surface of the connecting arm 305, and the outer surface of the wedge block 307 is rotated by a plane bearing The gear 310 is dynamically connected, and the outer surface of the gear 310 is fixedly connected with a connecting rod 311. The motor seat 202 is mainly used to install the servo motor 301. The slide groove 303 on the surface of the square rotating block 302 is used to install the slider 304 and limit it, so that the slider 304 can only slide up and down. When the slider 304 slides upward, the spring 306 will be squeezed to contract. The connecting arm 305 is used to connect the wedge block 307 and the slider 304. When the servo motor 301 is started, the slider 304 can be driven to rotate. During the process, the slider 304 will drive the wedge block 307 to rotate through the connecting arm 305, and the wedge block 307 will drive the gear 310 to rotate. The gear 310 and the wedge block 307 are connected by a plane bearing, so the gear 310 can also rotate.

[0026] The outer surfaces of the four detection trays 402 are symmetrically fixedly connected with connecting sleeves 405 and stabilizing plates 404. The four connecting sleeves 405 are fixedly connected to the connecting rod 311 by bolts. The top of the detection tray 402 is set in a cone shape. The top of the matrix gravity sensor 401 is equidistantly provided with weighing cups 406. The top of the detection tray 402 is equidistantly provided with a plurality of avoidance holes 403. The avoidance holes 403 and the weighing cups 406 are located at corresponding positions. The connecting sleeve 405 on the surface of the detection tray 402 and the connecting rod 311 on the surface of the gear 310 are connected by bolts. Therefore, when the gear 310 rotates horizontally and rotates on its own, it will drive the detection tray 402 to rotate synchronously. The top of the detection tray 402 is set to be conical. Therefore, when the water mist sprayed by the mechanical plant protection nozzle 504 falls on the top of the detection tray 402, it will flow around and finally flow into the funnel-shaped table 103 below. The weighing cup 406 is mainly used to receive the sprayed water mist. The detection end of the matrix gravity sensor 401 is placed inside the weighing cup 406, which is used to weigh the water mist received inside the weighing cup 406. The avoidance hole 403 is used to avoid the weighing cup 406.

[0027] The wedge block 307 cooperates with the ratchet plate 204, and a mounting groove 308 is provided at the bottom of the wedge block 307. A rotating rod 309 is rotatably connected between the inner surface walls of the mounting groove 308 through a rotating shaft. The gear 310 cooperates with the rack 205. A scale 407 is provided on the inner surface wall of the weighing cup 406. A connecting frame 110 is fixedly connected to the outer surface of the enclosure 105 near the rear side. The first industrial camera 111 and the second industrial camera 112 are fixedly installed on the inner top of the connecting frame 110. The first industrial camera 111 is arranged at an angle. When the wedge block 307 passes through the ratchet plate 204 area during horizontal rotation, it will be continuously subjected to an upward extrusion force under the action of the teeth and drive the slider 304 to move upward inside the slide groove 303. During the process, the slider 304 squeezes the spring 306 contracts, and when the spring 306 rebounds, it will push the slider 304 and the wedge block 307 downward, thereby forming an up and down shaking state. The connecting frame 110 is mainly used to install the first industrial camera 111 and the second industrial camera 112 at a position above the rear side of the enclosure 105, so as to collect images of the passing detection tray 402. According to the height of the water surface of the weighing cup 406 at the scale 407 at different positions in the image, the spray uniformity of the mechanical plant protection nozzle 504 can be judged. When the wedge block 307 and the top of the ratchet plate 204 are fitted and squeezed, the rotating rod 309 connected to the bottom of the wedge block 307 by the rotating shaft plays a role in converting the sliding friction between the wedge block 307 and the ratchet plate 204 into rolling friction, thereby reducing friction resistance and friction damage.

[0028] An electric push rod 502 is installed at the bottom of the installation shell 501, and the telescopic end of the electric push rod 502 is connected to the bottom of the installation plate 503. A flow valve 505 is installed on the top of the installation plate 503. The water outlet end of the flow valve 505 and the water inlet end of the mechanical plant protection nozzle 504 are connected through a water pipe. A water pump 506 is installed on the top of the installation shell 501, and the output end of the water pump 506 and the water inlet end of the flow valve 505 are connected through a water pipe. A downwardly extending water pumping pipe 507 is installed at the input end of the water pump 506, and the bottom end of the water pumping pipe 507 extends to the inside of the water tank 108. After the electric push rod 502 is started, it can drive the installation plate 503 to rise and fall, thereby adjusting the height of the mechanical plant protection nozzle 504. The water pump 506 cooperates with the water pumping pipe 507 to pump water out of the water tank 108 and transport it to the mechanical plant protection nozzle 504 to spray water mist. The flow valve 505 is used to adjust the water flow rate at the output end of the water pump 506.

[0029] The use steps of the present invention are as follows: when using the device to detect the spray uniformity of a plant protection machine nozzle, first install the machine plant protection nozzle 504 to be detected under the mounting plate 503, then start the water pump 506, pump out the water in the water tank 108 through the pumping pipe 507, and send the water into the machine plant protection nozzle 504 through the flow valve 505 and spray it downward in the form of water mist. After the water mist is sprayed out, it will enter the weighing cups 406 evenly arranged below. At this time, the matrix gravity sensor 401 will send the weight signals of the weighing cups 406 at different positions to the controller 102, and then the controller 102 controls the servo motor 301 to start and drive the square rotating block 302 to rotate 90°. During the process, the detection tray 402 will rotate with the square rotating block 302 and The weighing cup 406 filled with water is driven to rotate counterclockwise to the bottom of the connecting frame 110. At this time, the first industrial camera 111 takes pictures from 45° above the weighing cup 406, and the second industrial camera 112 takes pictures from top to bottom and transmits the image information to the controller 102. Then the servo motor 301 drives the square rotating block 302 to continue to rotate counterclockwise. At this time, the gear 310 connected by the slider 304, the connecting arm 305 and the wedge block 307 is engaged with the rear rack 205. The number of teeth on the gear 310 is twice that of the rack 205, and the gear 310 and the wedge block 307 are connected by a plane bearing. Therefore, the gear 310 will gradually flip 180° when passing the rear rack 205. During the process, the connecting rod 31 1 and the detection tray 402 connected to the connecting sleeve 405 and the gear 310 will be turned over synchronously, and the water in the weighing cup 406 will be poured into the funnel-shaped table 103. When the gear 310 is separated from the rear rack 205 area, the corresponding wedge block 307 will fit with the ratchet plate 204. During the rotation of the wedge block 307, the bottom of the wedge block 307 will be squeezed with the top of the ratchet plate 204, so the wedge block 307, the connecting arm 305 and the slider 304 will continue to move upward. During the upward movement, the slider 304 will squeeze the spring 306 inside the slide groove 303 to contract. When the sharp corner at the bottom of the wedge block 307 is engaged with the ratchet on the ratchet plate 204, the spring 306 will rebound and push the slider 304, the connecting arm 305 and the wedge block 3 07 moves downward, so when the wedge block 307 passes through the ratchet plate 204 area, it will drive the detection tray 402 and the weighing cup 406 to shake up and down, thereby ensuring that the water in the weighing cup 406 is completely poured out to avoid affecting the next detection result. After the wedge block 307 passes through the ratchet plate 204 area, the gear 310 will reach the rack 205 area close to the front side again. Therefore, under the cooperation of the gear 310 and the front rack 205, the detection tray 402 will drive the weighing cup 406 to flip upward again and rotate again to the bottom of the mechanical plant protection nozzle 504. At this time, under the action of the controller 102, the electric push rod 502 can adjust the height of the mounting plate 503 and the height of the mechanical plant protection nozzle 504, and the flow valve 505 controls the water flow delivery flow of the water pump 506.Then, the spray uniformity of the mechanical plant protection nozzle 504 at different heights and different flow states is detected. After the detection is completed, the image information collected by the first industrial camera 111 and the second industrial camera 112 is used to determine whether the water surface is at the same height at the scale 407 in the weighing cup 406 at different positions. The weight of the weighing cup 406 at different positions on the top of the matrix gravity sensor 401 is the same, so as to determine the spray uniformity of the mechanical plant protection nozzle 504 at different states. During the detection process, the servo motor 301 drives the detection tray 402 and the weighing cup 406 to rotate cyclically, so as to automatically complete the pouring action. No manual participation and redundant operations are required, and the degree of automation is high, which effectively improves the overall detection efficiency.

[0030] Embodiment 2: Figure 1 , Figure 3 , Figure 5 and Fig. 9 As shown, the difference between the embodiment and the enclosure 105 is that a plurality of balls 106 are movably connected to the top of the enclosure 105, and the outer surface of the balls 106 fits with the bottom of the stabilizing plate 404. When in use, the electric stabilizing plate 404 will rotate synchronously with the rotation of the detection tray 402, and the stabilizing plate 404 will move on the surface of the enclosure 105 during the rotation, thereby improving the stability of the detection tray 402. The balls 106 on the top of the enclosure 105 can convert the sliding friction between the enclosure 105 and the stabilizing plate 404 into rolling friction, thereby reducing friction resistance and friction damage.

[0031] Two avoidance grooves 107 are provided on the outer surface of the enclosure 105, and the positions of the two avoidance grooves 107 and the two racks 205 correspond to each other, and the positions of the enclosure 105 and the ball bearing 106 do not overlap. The controller 102 is electrically connected to the first industrial camera 111, the second industrial camera 112, the servo motor 301, the electric push rod 502, the matrix gravity sensor 401, the flow valve 505 and the water pump 506 through the line. When in use, when the gear 310 connected to the detection tray 402 moves to the rack 205 area and starts to rotate, the stabilizing plate 404 will synchronously reach the position of the avoidance groove 107, so the stabilizing plate 404 will complete the flipping in the avoidance groove 107. After flipping, the stabilizing plate 404 will return to a horizontal state and fit the top of the enclosure 105 and start to move. The controller 102 is mainly used to control the first industrial camera 111, the second industrial camera 112, the servo motor 301, the electric push rod 502, the matrix gravity sensor 401, the flow valve 505 and the water pump 506. The first industrial camera 111, the second industrial camera 112, the servo motor 301, the electric push rod 502, the matrix gravity sensor 401, the flow valve 505 and the water pump 506 cooperate with each other. The servo motor 301 will stop for 3 seconds every time it rotates 90 degrees, and the first industrial camera 111 and the second industrial camera 112 will start taking pictures synchronously. The water pump 506 will synchronously pump water through the water pumping pipe 507 and supply it to the mechanical plant protection nozzle 504 through the flow valve 505 to spray water mist. The matrix gravity sensor 401 will synchronously detect the weight and convert it into an electrical signal to send to the controller 102. According to the setting, the servo motor 301 drives the square rotating block 302 to rotate a fixed number of times, and the electric push rod 502 will push the mounting plate 503 to rise or fall to different heights, and the flow valve 505 will adjust the flow rate of water passing through.

[0032] The use steps of the present invention are as follows: during the operation of the device, when the detection tray 402 rotates horizontally, the stabilizing plate 404 on the surface will carry the top of the enclosure 105 and slide along, thereby improving the stability of the detection tray 402 during movement, and the ball 106 on the top of the enclosure 105 can convert the sliding friction between the enclosure 105 and the stabilizing plate 404 into rolling friction, reducing friction resistance and friction damage, and improving the stability of the detection tray 402 during rotation. When the gear 310 connected to the detection tray 402 moves to the rack 205 area and starts to rotate, the stabilizing plate 404 will synchronously reach the position of the avoidance groove 107, so that the stabilizing plate 404 will complete the flipping in the avoidance groove 107. After flipping, the stabilizing plate 404 will return to a horizontal state and fit the top of the enclosure 105 to start moving, thereby further improving the stability of the detection tray 402, avoiding the tilting of the detection tray 402 and the weighing cup 406, and improving the accuracy of the detection effect.

[0033] Embodiment 3: Figure 1-Figure 3 and Fig.10As shown, the difference between the combination embodiment and the embodiment is that a drain outlet 104 is fixedly connected to the bottom of the funnel-shaped table 103 near the right side, and the drain outlet 104 is located above the water tank 108. The drain outlet 104 is located at the lowest point of the funnel-shaped table 103. When in use, the water poured out of the weighing cup 406 will enter the funnel-shaped table 103, and flow to the lowest position of the drain outlet 104 and be discharged into the water tank 108.

[0034] A filter plate 109 is inserted between the front and rear inner walls of the water tank 108. The filter plate 109 is located on the right side of the drain outlet 104.
