[0023] Please see the attached Figure 1 -Attached Figure 5 The utility model relates to a flow rate measuring device for an agricultural plant protection machine, comprising a plant protection machine support beam 1 and a flow meter 2. The surface of the flow meter 2 is fixedly connected with a support ring 3. The inner wall of the support ring 3 is rotatably connected with two clamping blocks 4. The side walls of the two clamping blocks 4 abut against the side walls of the plant protection machine support beam 1. The inner walls of the two clamping blocks 4 are rotatably connected with a rotating plate 8. The side of one rotating plate 8 is fixedly connected with a connecting rod 5. The surface of the connecting rod 5 is slidably connected with the inner wall of the other rotating plate 8. The upper and lower sides of the flow meter 2 are fixedly connected with a connecting nozzle 7. The surface of the connecting nozzle 7 is threadedly connected with a threaded sleeve 9. The upper end face of the threaded sleeve 9 is fixedly connected to a limiting block 10. A slot 11 is provided on the side of the connecting nozzle 7. The inner diameter of the threaded sleeve 9 matches the size of the connecting nozzle 7. The number of support rings 3 is set to two, the number of clamping blocks 4 is set to four, the number of rotating plates 8 matches the number of clamping blocks 4, the size of the connecting rod 5 matches the size of the inner wall of the rotating plate 8, and the size of the inner wall of the support ring 3 matches the size of the flow meter 2.

[0024] In the first embodiment, a nut 6 is threadedly connected to the surface of the connecting rod 5, and the back of the nut 6 abuts against the front of one of the rotating plates 8;

[0025] Specifically, when the nut 6 is tightened on the connecting rod 5, the nut 6 can drive the two clamps 4 to rotate relative to each other through the rotating plate 8. The clamps 4 can install the entire device on the plant protection machine support beam 1, allowing the staff to quickly disassemble and install the entire device.

[0026] In the second embodiment, one end of the connecting nozzle 7 is connected to the flow meter 2, and the number of the limit blocks 10 matches the number of the card slots 11;

[0027] Specifically, the pesticide pipeline can be connected to the flow meter 2 through the connecting nozzle 7, so that the staff can monitor the amount of pesticide sprayed during the spraying operation.

[0028] Working principle:

[0029] First, the staff clamps the clamp 4 on the support beam 1 of the plant protection machine, and then tightens the nut 6 on the connecting rod 5. The nut 6 can drive the two clamps 4 to rotate relative to each other through the rotating plate 8, so that the clamp 4 can be clamped on the support beam 1 of the plant protection machine. Loosening the nut 6 can achieve quick disassembly. After the installation is completed, the staff can first put the threaded sleeve 9 on the pesticide pipe, and then connect the pesticide pipe to the connecting nozzle 7. At this time, the threaded sleeve 9 can be tightened on the connecting nozzle 7, and the limit block 10 can press the pipe against the connecting nozzle 7, and limit it through the deformation of the pipe in the slot 11. During the spraying operation, the pesticide in the pipe can be measured by the flow meter 2 to measure the pesticide flow rate.
