Abstract

<P>PROBLEM TO BE SOLVED: To provide a snow removing machine having a snow collecting part auger for smoothly transferring snow by improving biting-in performance even in the snow hardened in a frozen state. <P>SOLUTION: This snow removing machine is provided with a forwardly opening snow collecting part in a front part of a machine body. The snow collecting part auger constitutes an auger of the snow collecting part for performing continuous crushing by acting so as to cut the snow of the frozen state by claws, by spirally arranging one strip or a plurality of strips of a plurality of claws for molding a curved surface having a rake angle capable of transferring the snow in the snow collecting part central direction, on a shaft rotatably arranged around a horizontal shaft in the longitudinal direction. <P>COPYRIGHT: (C)2005,JPO&NCIPI

Description

  The present invention relates to a snow collecting auger structure at the front of a snowplow.

As a background art, “from the rotating shaft in which an auger housing that opens toward the front is provided at the front of the aircraft, and left and right belt-like blades in which the spiral winding direction is directed in the center are mounted in the housing. In a snow remover provided with an auger, a snow remover auger characterized in that a horizontal snow crushing blade is stretched between the outer peripheral portions of belt blades adjacent to each other. (Patent Document 1)
JP 2003-119743 A

  The auger of the snow collecting part in the prior art is provided with a spiral belt blade in the direction of transferring snow in the central part, and a snow crushing blade is spanned between the outer peripheral parts of the belt blades adjacent to each other to collect snow blocks and frozen snow. Although the snow is being cut, the outer periphery of the auger in the side view is formed into a circular shape with the entire circumference connected by a belt-like blade. There was a difficulty to inhibit.

  In order to solve the above problems, the present invention provides an auger device for a snow removal machine that has good bite characteristics even when it is frozen snow or the like and can smoothly transfer snow.

  In order to solve the above-mentioned problems, in the snowplow having a snow collecting part that opens toward the front at the front part of the machine body, the snow collecting part auger is a shaft that is provided to be rotatable around a horizontal axis in the longitudinal direction. Further, the auger of the snow collecting part is configured by arranging a plurality of claws formed in a curved shape having a scooping angle capable of transferring snow toward the center of the snow collecting part in a spiral manner. .

  Since the auger of the snow collecting part has a plurality of claws arranged in a spiral shape, the outer periphery of the auger does not have a circular shape with a continuous side view like a spiral belt, but the nails and claws on the outer part of the auger A gap is ensured between the two and the bite into frozen snow is improved.

  Each of the claws acts to cut frozen snow and becomes a fine snow mass by continuous crushing. Furthermore, the claw has a curved surface with a large angle, and the claw is continuously arranged in a spiral shape in a direction in which snow can be transferred, so that an effect similar to that of transferring with a spiral belt is obtained. The finely crushed snow mass can be collected at the center of the snow collecting portion and supplied to a blower provided on the rear side of the center for snow throwing.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. 1 is a front view of a snowplow according to the present invention, FIG. 2 is a cross-sectional view of a snow collecting portion, and FIG. 3 is a side view of the snowplow according to the present invention.

  Reference numeral 16 denotes a speed change case that decelerates power from the engine and rotationally drives the left and right rotating shafts 15. Reference numeral 11 denotes an auger, and a plurality of claw holders 14 are spirally welded to the rotating shaft 15, and the claw holder has a curved surface having a scooping angle so that snow can be transferred toward the center of the auger housing 10. A claw 13 formed symmetrically with respect to the center of the housing is inserted and fixed. In this embodiment, the claw holders are arranged in two spirals, but they may be arranged in one or more.

  Snow scraped to the central part of the auger housing 10 by the auger constituted by the claws 13 is supplied to a blower 17 provided on the rear side of the central auger and is snowed to a predetermined place through the chute 12 It is.

  In FIG. 3, reference numeral 1 denotes a traveling unit, which includes a driving wheel 5, a crawler 6 that is an infinite belt, and the like. Reference numeral 2 denotes an airframe. The traveling unit 1 described above is arranged on the left and right sides, the engine 4 is mounted on the upper part and covered with an airframe cover 7, and an operation unit 3 is provided on the rear part.

  The operation unit 3 is provided with a handle 9, a transmission lever 8, and the like. An auger housing 10 that opens forward is provided at the front of the machine body 2. In the auger housing 10, an auger 11 having a claw 13 disposed on a rotating shaft 15 in a spiral shape is provided. A blower 17 is provided in the blower cover 17a at the center rear of the auger, and the snow collected in the center by the auger is thrown through the chute 12 from the upper part of the blower cover 17a by the blower.

  The base portion of the chute 12 is configured to be capable of turning and turning, and is configured to be turned by a motor. The turning portion can be turned by a switch operation provided on the operation portion 3, thereby selecting a snow throwing direction.

  A first output pulley 4a is fixed to an output shaft protruding in front of the engine 4, and a lower auger drive pulley 11a is fixed to a shaft 18 protruding from the auger housing side. It is linked and connected via the drive.

  The driving force transmitted to the shaft 18 drives the blower 17 and the transmission case 16 provided in front of the blower. A worm and a worm wheel are provided in the speed change case 16 and, when decelerating, converts the rotational force in a direction perpendicular to the shaft 18 to drive the auger.

  On the other hand, a second output pulley 4b is fixed to an output shaft projecting from the rear of the engine, and is linked to the input pulley 20a of the lower traveling transmission 20 by a V-belt to drive the traveling transmission. The power converted by the travel transmission 20 is transmitted to the left and right drive wheels 5 to drive the crawler 6 so that the machine travels.
