Patent number: 9228308Abstract: A snow plow including a control unit for controlling the raising and lowering of an auger housing, a reset switch that can be operated by a worker, and a reset display light that illuminates in conjunction with the turning on of the reset switch. The control unit automatically raises and lowers the auger housing in accordance with the reverse and forward traveling of travel device, and automatically adjusts the auger housing to a horizontal position during forward travel of the travel device upon receiving an on signal from the reset switch. The control unit maintains the illuminated state of the illuminated reset display light according to the turning on of the reset switch, even when the travel device is traveling in reverse, and extinguishes the reset display light upon receiving a termination signal for terminating snow plowing work performed with an auger.Type: GrantFiled: October 20, 2014Date of Patent: January 5, 2016Assignee: HONDA MOTOR CO., LTD.Inventors: Jun Fukano, Tsutomu Mizoroke, Shinsaku Nakayama

Patent number: 9157201Abstract: A snow plow includes a control unit for controlling a raising/lowering drive mechanism so that an auger housing becomes horizontal, a relative angle detection unit for detecting the angle of the auger housing relative to a travel frame, and a horizontal detection unit for detecting the horizontal state of the auger housing. The control unit stops the raising/lowering drive mechanism when the control unit assess that either a first condition or a second condition is satisfied, the first condition being that the relative angle be zero and the second condition being that the auger housing be horizontal.Type: GrantFiled: October 20, 2014Date of Patent: October 13, 2015Assignee: HONDA MOTOR CO., LTD.Inventors: Jun Fukano, Tsutomu Mizoroke, Shinsaku Nakayama

Patent number: 9157202Abstract: A snow plow includes a control unit for raising an auger housing to a predetermined upper limit angle when travel device is reversing, and an acceleration sensor for detecting acceleration produced in the auger housing. The control unit determines an angle of inclination of the auger housing on the basis of the acceleration. When the travel device starts moving forward after having temporarily moved in reverse, the control unit sets an intermediate lowering target angle of inclination, which is in the lowering path of the auger housing from the upper limit angle to a pre-reversing angle of inclination, in accordance with the forward acceleration; lowers the auger housing at a given lowering speed from the upper limit angle to the intermediate lowering target angle of inclination; and lowers the auger housing at a gradually decreasing lowering speed from the intermediate lowering target angle of inclination to the pre-reversing angle of inclination.Type: GrantFiled: October 20, 2014Date of Patent: October 13, 2015Inventors: Jun Fukano, Tsutomu Mizoroke, Shinsaku Nakayama
