Annular soil groove testing stand

The invention provides an annular soil groove testing stand which comprises an annular soil groove, a running system, a measurement and control system and a power system. The measurement and control system and the power system connect with the running system. The annular soil groove is a closed soil groove, wherein straight line segments and arc segments are connected sequentially. The running system comprises a vertical double-layer operation track, a trolley, and a traction system. The operation track is arranged along the annular soil groove. The trolley is installed on the operation track and moves along the operation track. The traction system connects with the trolley. According to the invention, an annular soil groove is employed, and a functional trolley can be in continuous shuttling movement along the double-layer track. The annular soil groove testing stand has a soil recovery function, a field condition can be simulated repeatedly, a performance test of an agricultural machine and a part can be carried out, and a reliability test also can be carried out. Simultaneously, occupation of test ground can be reduced, since being not influenced by environment, climate and the like, the test can be carried out in an all-weather mode, and test and research periods can be effectively shortened.
