Snow removal machine
First Claim
1. A snow removal machine including a travel unit frame having a travel unit mounted thereon, and an auger housing having an auger housed therein and not only liftable and lowerable but also rollable relative to the travel unit frame, the snow removal machine comprising:
- a frame inclination angle detection section for detecting an inclination angle of the travel frame itself relative to a ground surface with which the travel unit is contacting;
a housing inclination angle detection section for detecting an inclination angle of the auger housing relative to the travel unit frame; and
an overall inclination angle evaluation section for evaluating an overall inclination angle of the auger housing relative to the ground surface on the basis of the inclination angle detected by the frame inclination angle detection section and the inclination angle detected by the housing inclination angle detection section,wherein the frame inclination angle detection section and the housing inclination angle detection section being provided on a part of the snow removal machine which does not make rolling motion together with the auger housing, andwherein the overall inclination angle evaluation section has a filter function that, upon determination that the snow removal machine is traveling at an accelerating or decelerating speed or making a turn, slowly changes a value of the inclination angle detected by the frame inclination angle detection section.

Abstract
A snow removal machine including a travel unit frame having travel units, and an auger housing liftable, lowerable and rollable relative to the travel unit frame. The machine also includes: a frame inclination angle detection section for detecting an inclination angle of the travel frame relative to a ground surface; a housing inclination angle detection section for detecting an inclination angle of the auger housing relative to the travel unit frame; and an overall inclination angle evaluation section for evaluating an overall inclination angle of the auger housing relative to the ground surface on the basis of the inclination angles detected by the two detection sections. The two detection sections are provided on a part of the machine which does not make rolling motion together with the auger housing.

10. A snow removal machine comprising:
-
a travel unit frame having a travel unit mounted thereon; a machine body frame having a rear end portion pivotally connected to the travel unit frame for undergoing pivotal movement in a vertical plane, the machine body frame being not rollable relative to the travel unit frame; an auger housing rollably mounted on a front end portion of the machine body frame, the auger housing having an auger housed therein and being not only liftable and lowerable but also rollable relative to the travel unit frame; a frame inclination angle detection section for detecting an inclination angle of the travel frame itself relative to a ground surface with which the travel unit is contacting; a housing inclination angle detection section for detecting an inclination angle of the auger housing relative to the travel unit frame; and an overall inclination angle evaluation section for evaluating an overall inclination angle of the auger housing relative to the ground surface on the basis of the inclination angle detected by the frame inclination angle detection section and the inclination angle detected by the housing inclination angle detection section, wherein the frame inclination angle detection section and the housing inclination detection section are provided on a part of the snow removal machine which does not make rolling motion together with the auger housing, wherein the frame inclination angle detection section is provided on the travel unit frame and the housing inclination angle detection section is provided on the machine body frame, and wherein the housing inclination angle detection section comprises a potentiometer fixedly mounted on the front end portion of the machine body frame, the potentiometer having a rotary input shaft extending parallel to an axis of rolling movement of the auger housing, and a link mechanism operatively interconnecting the input shaft of the potentiometer and a part of the auger housing such that rolling movement of the auger housing is transmitted via the link mechanism to the input shaft of the potentiometer. - View Dependent Claims (11)
