The height of the inner drainage holes 12 is higher than the height of the outer drainage holes 10. Figure 6 As shown;

[0031] The liquid spraying system includes a nozzle slide rail frame 13 and a nozzle frame 14. The nozzle slide rail frame 13 is installed on the side of the drainage platform 4. A slide seat 15 is mounted on the nozzle slide rail frame 13. The slide seat 15 can slide up and down on the nozzle slide rail frame 13. An adjusting bolt 16 is threadedly installed on the slide seat 15. The end of the adjusting bolt 16 is in pressure contact with the nozzle slide rail frame 13. One end of the nozzle frame 14 is fixed on the slide seat 15. A detection nozzle 17 is installed on the other end of the nozzle frame 14. The detection nozzle 17 is connected to a nozzle hose 18.

[0032] The detection frame 1 is also provided with a plurality of groups of buoyancy-type liquid volume detection mechanisms, which are arranged one by one in correspondence with the detection cells 8. Each group of buoyancy-type liquid volume detection mechanisms includes a fixed rod 19, a track plate 20, a slide rod 21, a linkage turning rod 22, an indicating turning rod 23 and a float 24. Figure 7 As shown, the float 24 includes a water retaining platform 25, a movable long rod 26 is fixed to the center of the bottom surface of the water retaining platform 25, and the four sides of the water retaining platform 25 are connected to floating blocks 28 through connecting rods 27. The float 24 is located in the detection unit cell 8, and the movable long rod 26 is inserted into the inner drainage pipe 11 from top to bottom;

[0033] like Figure 8 and Fig. 9 As shown, the fixed rod 19, the track plate 20 and the slide rod 21 are all fixed at the bottom of the drainage platform 4, and the fixed rod 19, the track plate 20 and the slide rod 21 are arranged in sequence from back to front, the movable long rod 26 is located between the fixed rod 19 and the track plate 20, the lower part of the track plate 20 is provided with a track slide hole 29, the slide rod 21 is sleeved with a slide sleeve 30, the middle part of the linkage turning rod 22 is fixed with a short shaft 31, the short shaft 31 is located in the track slide hole 29 of the track plate 20, and the short shaft 31 is located in the track slide hole 29 of the track plate 20. 1 can slide in the track slide hole 29, the lower end of the movable long rod 26 and the rear part of the linkage crank rod 22 are connected with a short rocker 32, and the two ends of the short rocker 32 are respectively installed on the lower end of the movable long rod 26 and the linkage crank rod 22 by hinged manner, the lower end of the fixed rod 19 and the rear end of the linkage crank rod 22 are connected with a long rocker 33, and the two ends of the long rocker 33 are respectively installed on the lower end of the fixed rod 19 and the rear end of the linkage crank rod 22 by hinged manner, and the front end of the linkage crank rod 22 is hinged on the sliding sleeve 30;

[0034] One end of the indicating rod 23 is fixed on the sliding sleeve 30, and a plurality of indicating long holes 34 are opened on the scale plate 2. The other end of the indicating rod 23 passes through the indicating long holes 34. A pointer 35 is arranged at the end of the indicating rod 23, and a liquid medicine volume scale line is arranged on one side of the indicating long hole 34. The pointer 35 points to the liquid medicine volume scale line.

[0035] The movable long rod 26 can move up and down under the influence of the float 24. When the movable long rod 26 moves, it pushes and pulls the linkage crank rod 22. Since the short shaft 31 arranged in the middle of the linkage crank rod 22 is also located in the track slide hole 29, the movement of the linkage crank rod 22 is restricted by the track slide hole 29, and finally the front end of the linkage crank rod 22 moves vertically up and down. It should be noted that the shape of the specific track slide hole 29 can be made by inversely calculating the motion trajectory of the vertical movement of the front end of the linkage crank rod 22, and finally the front end of the linkage crank rod 22 drives the sliding sleeve 30 to slide on the slide rod 21.

[0036] The mechanical inspection table for inspecting the uniformity of sprinkler nozzles of this embodiment is as follows: the whole device is placed on a horizontal table, and then the drainage trough 5 is stably placed on the inspection trough 3 through four sets of positioning angle steels 6, and then the required height of the inspection nozzle 17 is determined, and the adjusting bolt 16 is tightened to fix the nozzle frame 14, and then the nozzle hose 18 is connected to the liquid medicine source, and the inspection nozzle 17 starts to spray liquid medicine, and the liquid medicine spraying operation is terminated after a period of time, and the liquid medicine flows from the drainage cavity 7 of the drainage trough 5 into the corresponding detection cell 8 in the detection trough 3 (the height of the liquid medicine flowing into the detection cell 8 needs to be lower than 1 / 4 of the detection cell 8). On the water retaining platform 25), the floating water block 28 of the float 24 in the detection cell 8 moves upward under the action of buoyancy, driving the movable long rod 26 to move vertically upward, and the movable long rod 26 pulls the rear part of the linkage crank 22 through the short rocker 32, and the linkage crank 22 rotates with the short axis 31 as the fulcrum, so that the front end of the linkage crank 22 moves downward, and the front end of the linkage crank 22 drives the sliding sleeve 30 to slide downward, and the sliding sleeve 30 drives the indicating crank 23 to move downward, and finally the pointer 35 moves downward to point to a certain scale of the liquid medicine volume scale line, that is, the corresponding liquid medicine volume in the detection cell 8, and the distribution of the liquid medicine can be calculated later to realize the detection operation.

[0037] After the detection is completed, the detection tank 3 is lifted up, the external drain pipe 9 moves upward on the internal drain pipe 11, and finally the external drain hole 10 rises to a position corresponding to the internal drain hole 12, and the liquid in the detection tank 3 is finally discharged through the external drain hole 10 and the internal drain hole 12.

[0038] In order to facilitate the upward movement of the detection tank 3, an N-shaped drainage handle 36 is installed on the drainage platform 4. The two ends of the drainage handle 36 are respectively hinged to the two sides of the drainage platform 4 through a pin shaft 37. Dome plates 38 are arranged at both ends of the drainage handle 36. Stopping columns 39 are fixed on both sides of the detection tank 3. The outer edges of the two dome plates 38 are in contact with the two stopping columns 39. Pressing the drainage handle 36 downward causes the dome plate 38 to lift the stopping columns 39, and the detection tank 3 can be moved upward for a distance. After the upward movement, the outer drainage hole 10 rises to a position corresponding to the inner drainage hole 12.
