Specific embodiments
[0026] Embodiment: As Figures 1 to 2 shown, a plow tip test bench includes a test box 1. A mounting plate 2 is fixedly installed on the top of the test box 1 through bolts. A bracket 3 is fixedly connected to the top of the mounting plate 2. A reduction motor 4 (a well-known technology) is fixedly installed on the top of the bracket 3. A rotating shaft 5 is rotatably connected between the test box 1 and the mounting plate 2. A fixing bracket 6 is fixedly installed on the outer surface of the rotating shaft 5. A test plow tip 7 is fixedly installed on each side of the fixing bracket 6. The figure shows the plow tip of a moldboard plow. Typical soil is placed inside the test box 1. The typical soil is various terrains simulated by stones, sandy soil, compacted land, gobi desert, etc. Since the structure is simple, no specific detailed introduction is made here.
[0027] A driving gear 41 is fixedly installed at the output end of the reduction motor 4. A driven gear 51 is fixedly installed on one side of the rotating shaft 5. The driving gear 41 and the driven gear 51 are meshed with each other.
[0028] The test box 1 includes a square steel frame 11. Four side plates 12 are welded inside the square steel frame 11. A bottom plate is fixedly installed on one side of the square steel frame 11. A number of reinforcing ribs 13 are welded inside the square steel frame 11 to enhance the mechanical structure of the lifting device and the stability of the lifting device.

[0034] The working principle of the plow tip test bench is as follows:
[0035] 1) During the test, fix the test plow tip 7 for the test on the fixing frame 6 by bolts, and add typical soil into the test box 1.
[0036] 2) Start the reduction motor 4. The reduction motor 4 rotates at a constant speed under the control of an external main controller. Under the cooperation of the driving gear 41 and the driven gear 51, the rotating shaft 5 is driven to rotate, and then the fixed disk 61, the connecting plate 62 and the connected test plow tip 7 are driven to rotate, and then the test is carried out.
[0037] 3) Further, by selecting connecting plates 62 of different lengths, the service life and performance of the test plow tip 7 under different tillage widths and depths can be simulated, and the use is very convenient.
