Abstract：Aiming at the problems of complex cutter head form of full-section rectangular roadheader in existing coal mine roadway，difficultyin one-time tunneling forming of full-section.A method for implementing rectangular truncation was proposed based on the principle of Reuleaux motion，a kind of eccentric shaft planetary gear drive Reuleaux triangle single cuter head was designed based on the proposed method， and the motion trajectory simulation was carried out.A full-section rectangular cutterhead cuttng test bench was built and multiple sets of tests under stable cutting states were carred out.The test results show that： the center fishtail cutter may increase the stability of the cutting processes，the vibration of X，Y and Z directions is greatly respectively reduced，the minimum reduction is as 42.107% ，and the maximum is as 51.753% . The stable cutting rock sample tests under 11 groups of different cutting parameters were carried out，and the relationship among torque，oil pressure and cuting parameters was obtained.A concept of equipment economic cutting parameter region was proposed. The economic cuting parameter area of the cutterhead designed under the condition of the test rock sample is determined to be n（N-p）min=[6.6，9.8]r/ min; v（N-p）min=[14.25，18.3]mm/min .The graphic difference rates among the theoretical section，the simulation section，the test section and the standard square are as 3.18%，5.09% and 6.64% respectively，which verifies the feasibility of the cutter to realize rectangular cutting.
