The pointer 153 is mounted on the impact beam 15 and can point to the scale 16 to measure the height of the impact beam 15. At the same time, the laser sensor 17 is arranged on the rack 11 to measure the lifting height of the impact beam 15. The laser sensor 17 is preset to a certain height, and the pointer 153 points to the scale 16, forming a double check effect, which improves the accuracy of the impact stroke of the impact test assembly, and then improves the test accuracy.
[0034] The implementation principle of the agricultural machine blade impact test device is that the test top plate 23 can be freely adjusted at multiple angles under the action of the universal ball hinge seat, so that the angle of the measured blade impacted is adjusted, and then the multi-angle impact test of the measured blade can be realized. At the same time, when the inclination angle and direction of the test top plate 23 are adjusted by the universal ball hinge seat, the corresponding telescopic column 28 will be extended or retracted, and then the telescopic column 28 is locked by the locking bolt 271, so that the test top plate 23 is relatively stable in the corresponding inclined state. The test table 2 and the test punch 152 can be replaced according to different test scenes, and the gravity of the stamping can also be adjusted by increasing or decreasing the counterweight 151.
