Definitions

  • This invention relates to a guideshooter swiveling controller for a snowplow.
  • Snowplows for home use as disclosed in the Japanese Patent Application Laid-Open No. 194307/1987, comprises a propelling body with a crawler and a snow removing machine mounted at the front of the body.
  • the snow removing machine has an auger for crushing and gathering snow by a screw action, a blower for throwing the gathered snow, and a guideshooter for guiding the snow discharged from the blower onto sideways.
  • the guideshooter consists of a vertical cylinder section rising up from the blower and a curved cylinder section formed at the upper end of the vertical cylinder section, so that the snow discharged from the blower can be led to a high position before being thrown onto roadsides.
  • To change the snow discharging direction it is necessary to swivel the guideshooter with respect to the snowplow body.
  • the guideshooter is swiveled by manually rotating a crank handle located at an operating section of the snowplow.
  • the reduction ratio of a power transmission mechanism must be set large so that the guideshooter can be turned manually and will not rotate of itself while the snowplow is in operation. This in turn results in a corresponding increase in the number of revolutions that the crank handle must be operated.
  • the conventional snowplow has another disadvantage of a bad operability. That is, during the snow clearing work, an operator must perform complicated operations, i.e., rotate a crank handle while at the same time steering the snowplow.
  • the object of the invention is to provide a snowplow that can control swiveling of a guideshooter with a simple operation.
  • Another object of the invention is to provide a snowplow in which the guideshooter is prevented from swiveling in excess of an allowed range.
  • a snowplow according to this invention consists of a propelling body 1 and a snow removing machine 2.
  • the snowplow travels on snow by driving a pair of right and left crawlers 4 by an engine 3.
  • the snow removing machine 2 consists of an auger 5 for crushing and gathering snow and a blower 6 for blowing and scattering the collected snow.
  • the auger 5 has its shaft rotatably arranged perpendicular to the direction of snowplow travel and rotated by the engine 3.
  • the auger 5 as it is being driven collects and draws snow lying in front of the snow removing machine 2 toward the blower 6.
  • An auger cover 7 is provided around the auger 5.
  • the rotating shaft of the blower 6 is arranged parallel to the direction of snowplow travel and rotated by the engine 3.
  • a cylindrical blower cover 8 is provided enclosing the blower 6.
  • a snow discharge port is formed in the blower cover 8 above the blower 6.
  • the guideshooter 9 has a ring flange 10 formed around the lower part thereof.
  • the flange 10 is formed with teeth 11 on its outer circumference at least over the swiveling range A of the guideshooter 9.
  • the teeth 11 is engaged with a worm gear 12.
  • a rotating shaft 14 of the worm gear 12 has a contact rotating member 15 mounted thereon, which is coupled to the rotating shaft 14 by a key 16 so that it is only axially slidable. As the contact rotating member 15 rotates, it drives the worm gear 12 through the rotating shaft 14.
  • the contact rotating member 15 has an annular recess 17 formed on its outer circumference, with tapered engagement surfaces 17a, 17b formed on each side of the recess 17.
  • a boss 38 is formed integral with an extends from one side of the contact rotating member 15.
  • the boss 38 is attached with a collar 19 with a bearing 18 interposed therebetween.
  • the collar 19 is rotatable relative to the contact rotating member 15, and moves along with it when the contact rotating member 15 moves axially along the rotating shaft 14.
  • On the outer circumference of the collar 19 near one end is formed an annular groove 20, with which pins 23 of a junction lever 22 shown in Figures 4a, 4b are engaged.
  • the junction lever 22 is fixedly attached with wires 24, 25, which are connected to operation levers on each side (not shown) located near steering handles 39 of the propelling body 1.
  • the wire 24 is pulled, rotating the junction lever 22 in a direction of arrow D, which in turn causes the collar 19 and the contact rotating member 15 to be slid in a direction of arrow F.
  • the wire 25 is pulled, rotating the junction lever 22 in a direction of arrow E. This in turn causes the collar 19 and the contact rotating member 15 to be slid in a direction of arrow G.
  • compression springs 26, 27 which are so set that the contact rotating member 15 is at rest at a central neutral position.
  • An output pulley 28 for the crawler 4 and the auger 5 is secured to the output shaft 3a of the engine 3 by a bolt 29 and a nut 30.
  • a bevel member 32 is secured to the front end of the bolt 29 and is placed close to the annular recess 17.
  • a taper surface 31 of the bevel member 32 and taper surfaces 17a, 17b of the annular recess 17 are out of contact when the contact rotating member 15 is at the neutral position. They contact each other when the contact rotating member 15 moves along the rotating shaft 14 in either direction.
  • the rotation of the bevel member 32 is transmitted through the contact rotating member 15 to the worm gear 12, which in turn causes the guideshooter 9 to rotate. In this way, the contact rotating member 15 and the bevel member 32 combine to work as a clutch 13 of the swiveling mechanism 40.
  • An automatic release mechanism 33 is provided to the swiveling mechanism 40.
  • the collar 19 has an arm 35 erected therefrom whose end is rigidly attached with a rod 34 extending parallelly with the shaft 14.
  • the rod 34 is supported in such a way as to be axially movable along the shaft 14.
  • Secured to the rod 34 is an arm 36 extending above the flange 10 of the guideshooter 9.
  • the flange is provided with two projections 37a, 37b that define the swiveling limits of the guideshooter 9. When the guideshooter 9 swivels in excess of these limits, the projection 37a or 37b engages with the arm 36, moving the rod 34 axially along the shaft 14, forcibly bringing the bevel member 32 out of engagement with the contact rotating member 15.
  • the contact rotating member 15 moves in the direction of arrow F, the taper surface 17a comes into line contact with the taper surface 31 of the bevel member 32, with the result that the contact rotating member 15 starts to rotate in the direction of arrow H.
  • the rotation of the contact rotating member 15 is transmitted through the shaft 14 to the worm gear 12 which is rotated in the same direction of arrow H, causing the guide- shooter 9 to turn clockwise.
  • the contact rotating member 15 rotates in the direction of the tail of the arrow H, opposite to the direction of the above case, and its rotation is transmitted through the shaft 14 to the worm gear 12 which is rotated in the direction of the tail of the arrow H, swiveling the guideshooter 9 counterclockwise.
  • the left-hand operation lever is released allowing the contact rotating member 15 to return to the neutral position.
  • the contact rotating member 15 parts from the bevel member 32 bringing the swiveling guideshooter 9 to a halt.
  • the swiveling operation of the guide­shooter 9 can very easily be done while steering or other operations are being performed simultaneously.
  • taper surface 17a and the taper surface 17b are formed on a single member, they may be formed on separate members, in which case the bevel member 32 is made to engage with the taper surface 17b by the wire 24 and with the taper surface 17a by the wire 25.
