[0033] The working principle of a drip irrigation belt flow uniformity detection device proposed by the present invention is that when using the device, the drip irrigation belt 2 is first fixed on the workbench 1 by a clamping mechanism, so as to achieve quick disassembly and installation and improve work efficiency. Then, the measuring cup 5 is fixed by a fixing mechanism and moved to the bottom of the drip port 4. Finally, the water pump 9 is started by a control button 8, so that the water in the water tank 3 is transported to the inside of the drip irrigation belt 2. At the same time, the water is filtered by a filter net 7 to prevent the drip irrigation belt 2 from being blocked and affecting the detection result.

[0034] The anti-leakage mechanism can be used to prevent water from leaking out of the slot 6, thereby preventing water resources from being wasted.

[0035] In one embodiment, for the above-mentioned clamping mechanism, the clamping mechanism includes a fixed plate 10 disposed on the workbench 1 , a protruding base block 11 is fixedly mounted on one side of the fixed plate 10 , and a first disc 12 is rotatably mounted on the fixed plate 10 .

[0043] Furthermore, by means of the sliding installation of the moving plate 17 and the placement groove 18 , the measuring cup 5 can be driven to move to the bottom of the drip port 4 in a timely manner.

[0048] It is worth noting that the two ends of the block 22 are in contact with the inner wall of the notch 6, thereby preventing the filter screen 7 from being washed away by the water flow.

[0049] When the filter screen 7 is replaced, the first connecting plate 23 is first moved to the slot 6, and the slot 6 is covered with the first protective shell 24, and then the second connecting plate 26 is moved to the slot 6, and the second protective shell 25 is sleeved on the first protective shell 24, and finally the first connecting plate 23 and the second connecting plate 26 are fixed with bolts 27 to prevent water from flowing out of the slot 6.
