Detailed Description

The utility model discloses a plant protection unmanned aerial vehicle sprays electronic scraper blade of test bench comprises preceding support column 14, back support column 15, fixed cross beam 8 and step motor 6. Preceding support column 14 include preceding branch 1 and preceding support column 3 that moves, back support column 15 includes back branch 10, back removal loop bar 12, and preceding support column 14 highly is less than the height of back support column 15, preceding 3 lower extremes of moving loop bar and preceding 1 upper ends of branch all are equipped with more than one pinhole one 2 that correspond each other, preceding support column 14 is constituteed to the lower extreme of preceding 1 upper end and preceding moving loop bar 3 cup joints the back of inserting the round pin axle together, back moving loop bar 12 lower extreme and back 10 upper ends all are equipped with more than one pinhole two 11 that correspond each other, back support column 15 is constituteed to the upper end of back support bar 10 and the lower extreme of back moving loop bar 12 cup joints the back of inserting the round pin axle together. Before the experiment is started, the pin shafts can be inserted into the corresponding pin holes I2 and II 11 according to the height of the test bed 16, so that the heights of the front support column 14 and the rear support column 15 are adjusted to be suitable for the height of the test bed 16.

The upper surface of preceding removal loop bar 3 and back removal loop bar 12 all has the inclination the same with test bench 16, and the top of preceding removal loop bar 3 and back removal loop bar 12 all is fixed with fixed plate 4, and the equal perpendicular baffle 5 that is connected with of fixed plate 4 upper surface, all is fixed with between the baffle 5 on corresponding preceding removal loop bar 3 and back removal loop bar 12 top and sets up screwed lead screw 7 on the surface, the one end of two lead screws 7 all is fixed with step motor 6, step motor 6 and driver 13 electric connection. A fixed cross beam 8 is connected between the two lead screws 7, threaded holes are formed in the two ends of the fixed cross beam 8 and sleeved on the lead screws 7 in a sleeved mode and are in threaded fit with the lead screws, more than one screw hole is formed in the fixed cross beam 8, and a scraper 9 with the lower end in a pointed angle shape matched with the V-shaped groove of the test bed 16 is fixed at each screw hole. The scrapers 9 on the fixed cross beam 8 are sequentially connected to form a dog-tooth shape which is matched with the V-shaped groove of the test bed 16.
