Embodiment Construction

[0026] Hereinafter, embodiments of the present invention will be described with reference to the drawings. In this embodiment, front and rear, left and right, and up and down refer to snow removal when the snow blower 10 is standing on the ground X in the basic posture of the snow blower 10 (the screw rotor 16 and the propelling part 18 are in contact with the horizontal ground X). The attitude of the machine 10) is front and rear, left and right, and up and down based on the view of the screw rotor 16 side from the side of the idler wheel 22. Furthermore, snow blower 10 is not the type that an operator rides on. The snow blower 10 is a type in which an operator stands on the ground or on a snowy field, and performs snow removal work while holding an armrest 28 described later. The snow blower 10 is a snow blower of a type that moves by the propulsion force of a propulsion unit 18 rotationally driven by a drive source 14 described later, that is, a self-propelled snow blower....

Abstract

A snow blower includes a driving source, a propelling section, and a free wheel, and is arranged to move forward smoothly as a result of the propelling section being driven by the driving source. The snow blower further includes a frame, the driving source supported by the frame, an auger rotated based on a driving force generated by the driving source, the propelling section supported by the frame at a more rearward position than the auger and rotated based on the driving force generated by the driving source, and a pair of free wheels rotatably supported by the frame. When the snow blower is in its basic attitude, the free wheels have their center of rotation at a more rearward position than a lower end portion of the propelling section, and have their lower ends at a higher position than a lower end portion of the propelling section.

Description

technical field [0001] The invention relates to a snow removal machine, in particular to a self-propelled snow removal machine. Background technique [0002] The current proposal has a self-propelled snow blower. [0003] For example, the snow blower described in Japanese Patent No. 4317140 has: a screw rotor (auger); an engine; a pair of wheels (idling wheels) arranged behind the screw rotor; A pair of training wheels between. A pair of wheels are set to spin freely. For example, when only the snow blower is moved on the road, the auger can be raised from the ground with a pair of wheels as fulcrums, and the body can be supported by the pair of wheels to move the snow blower forward or backward. During snow removal operations, the helical rotor is rotationally driven by the engine. The pair of auxiliary wheels is connected to the screw rotor via a belt, and the rotation of the screw rotor is transmitted to the pair of auxiliary wheels via the belt. Thereby, the auxilia...
