Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a snow blower, particularly a so-called snow throwing type snow blower in which an auger 2 provided at the front of a machine body 1 scrapes snow to the center or one side, and a blower 3 discharges the snow through a discharge tube 4. This relates to snow removal machines.

Even though conventional snow blowers are walk-operated, they have a frame structure, making them bulky and having a high center of gravity, resulting in poor control stability. There was a risk that this would freeze and impair functionality.

In view of the above-mentioned points, an object of the present invention is to lower the center of gravity of a walking-operated snow blower and to obtain a compact and robust body structure that prevents snow from entering the body of the body.

The purpose is also to streamline the mounting of the onboard fuel tank and handles of various operating systems. The structure of the snow blower of the present invention will be explained with reference to the illustrated embodiment.

The main parts of the fuselage 1 include an auger housing IA that is open toward the front, and a box-shaped body IB that is integrally connected to the rear of the auger housing IA and has an open upper surface. Both ends of the auger 2 are supported by the left and right side walls of the housing IA to cover the rear of the auger 2.

Further, a guide duct 5 connected to the discharge tube 4 is integrally provided in the center of the auger housing IA. The rear wall IBI of the box-shaped body IB is removable, and the engine 6 is guided and fixed on the bottom surface of the body IB. The output shaft 7 of the engine 6 is made to protrude from one side 182 of the box-shaped podium IB, and a belt transmission mechanism 8 with a clutch is provided between the shaft 7 and the auger ball. The mechanism 8 is covered by side covers 9. In addition, axles 10 and 1 are mounted on both left and right walls of the box-shaped body IB.
0 is penetrated and supported, and wheels 11, 11 are attached to this so that they can rotate freely.

In the snow blower of the embodiment, the auger 2 functions as a driving force for traveling, and the wheels 11 described above serve as driven wheels. At the rear end of the box-shaped body IB, a gate-shaped frame 12 is mounted across the upper portion between the left and right side walls thereof, and a small-sized gate-shaped frame 13 is further mounted on the frame 12.

A fuel tank 14 placed between the upper and lower portal frames 12 and 13 and mounted on the lower frame 12 is fixed to the upper frame with screws 15. Brackets 121, 13 protruding from the upper and lower gate-shaped frames 12, 13
The fuel cock opening/closing handle 16, the choke operating handle 17, etc. are supported by penetrating the brackets 121, 131 protruding from the bracket 1.

A crank handle 18 for controlling the direction of the discharge tube and a recoil starter knob 19 also pass through the upper frame 13 and are freely rotatably supported via pushers. The base 201 of the control handle 20, which extends diagonally upward to the rear of the fuselage 1, is fixed along both sides of the gate-shaped frame 12 and both sides of the box-shaped body IB.

A cover 21 covers the top of the box-shaped body IB, the fuel tank 14, and various operating handles 16 to 19 from above the fuselage 1, that is, from around the base of the ejection tube 4.

The rear surface 211 of the cover 21 is separately removable. 25 is a bracket for mounting the force bar.

A downward gap S is provided between the lower end edge of the cover rear surface 211 and the upper end edge of the rear wall IBI of the box-shaped body IB, so that the inside and outside of the box-shaped body IB are passed through.

The exhaust pipe 22 of the engine 6 comes out from the gap S, and a muffler 23 is attached to the end of the exhaust pipe 22. A supply port 141 of the fuel tank 14 is exposed on the surface of the cover 21.

24 is a scraper.

As described above, the snow blower of the present invention includes an auger housing IA that pivotally supports the auger 2, covers the rear surface of the auger 2, and forms a guide duct 5 to the discharge tube 4. is installed as the main part of the aircraft, and inside the box-shaped body IB are the engine 6 and its operating systems 16 to 16.
Since it incorporates 19 etc. and fuel tank 14,
The auger hauling IA and box-shaped body IB have a so-called monocoque structure, which is strong and lightweight, and prevents snow from penetrating from below, allowing the minimum ground clearance to be as low as possible, lowering the center of gravity of the aircraft, and improving maneuverability. Or, it has excellent stability during transportation and handling. And the auger housing IA・
Since the upper part of the box-shaped body IB is covered with the cover 21, it is possible to prevent snow from entering from above.

Although the temperature inside the engine room increases due to the box-shaped body IB and the cover 21, a gap S is provided between the box-shaped body IB and the cover 21 in the rear part of the aircraft where there is little snow penetration, so that the air inside and outside can be There is circulation and the engine room can be maintained at an appropriate temperature.

Further, the snow blower of the present invention is provided with gate-shaped frames 12 and 13 that straddle the upper part between both side walls of the box-shaped body IB of the machine body, and a fuel tank 14 and handles 16 to 19 for various operating systems are attached to the frames 12 and 13. Since the gate-shaped frames 12 and 13 that are supported, that is, fuel tank stays, are also used as support parts for the steering wheel race, the stay structure of each of the above members is simplified.
This is effective in reducing the weight of the aircraft.
