JPH11124826A - Breaking device of iced snow face for snow remover - Google Patents

Abstract

PROBLEM TO BE SOLVED: To smoothly and continuously remove snow by fitting a breaking rotor for crushing iced snow face to the front side of an auger, which can be folded and turned upward and fixed when it is not required. SOLUTION: An auger case 8 is provided at the front part of the main frame 4 and the auger is supported so as to cross the advancing direction at right angles and send snow scraped from the right and left sides to the central part to an impeller 6 and discharge it through a chute 14. A cylindrical shaft-like breaking rotor 12 radially having a number of claws 13 is supported at the front end of the arm 15 supported by the support shafts of both side walls of the auger case 8. A chain is hung on a driving sprocket provided at the main shaft 10 and the breaking rotor 12 to rotate the breaking rotor 12. The arm 15 is folded upward and fixed by a stopper pin 16 when it is not used and the chain is removed. Since the breaking rotor 12 crushes forcibly iced snow face on the surface of a road and feed it to the auger, the scraper of the auger housing is not caught by the surface and a smooth and continuous snow-removing work can be carried out.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a crushing rotor which is an auxiliary device corresponding to an icy snow surface of a snowplow having a scraper auger in front of a self-propelled body.

[0002]

2. Description of the Related Art In snowy areas, especially near spring, the surface layer of the ground becomes frozen. On the icy snow surface, the scraper forming the bottom surface of the auger housing advances while crushing, but when the icy layer is hard or thick, the oscillating device swings up and down to travel. Japanese Utility Model Laid-Open Publication No. 3-72930 discloses a method in which a scraper is crushed by vertically swinging a bottom scraper of a housing.

[0003]

In the construction in which the bottom scraper of the auger housing is swung up and down, the crushing effect is reduced when the freezing plate is thickened, and at the same time, when the self-propelled machine runs, it is interrupted by the reaction force of the scraper. There was a problem that vibration occurred and running became impossible.

[0004]

In order to solve the above-mentioned problems, an auger case attached to the front of a self-propelled body is provided with an auger that cuts snow and scrapes the snow into a snow removal part so as to be rotatable. In the snow removing machine, a crushing rotor for crushing the icy snow surface is located in front of the auger, and when unnecessary, the crushing rotor is folded and rotated and fixed to the upper portion to provide an icy snow surface crushing device for a snow removing machine. It is.

[0005]

According to the present invention, the crushing rotor provided at the lower front portion for shaving snow cover forcibly crushes the icy snow surface on the road surface and supplies it to the auger. The scraper portion of the auger housing is pulled to the surface. The snow removal work can be performed smoothly and continuously without hanging. Also, in the case of fresh snow where there is no icy snow surface on the road surface, the crushing rotor is turned upward to be folded and fixed. When the snow layer is thick, it may be driven and used as a two-stage auger rotor.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a side view of a preferred embodiment of the present invention, in which a main part is shown in cross section. FIG. 2 is a front view of a main part. Reference numeral 1 denotes an engine mounted on the upper part of the main frame 4, and reference numeral 3 denotes a crawler, which is disposed on both sides of the main frame 4. Reference numeral 2 denotes a handle, which is obliquely provided behind the main frame 4.

Reference numeral 8 denotes an auger case provided in front of the main frame 4, and supports an auger 9 in a direction perpendicular to the traveling direction. The auger 8 scrapes the snow from the left and right toward the center and sends it to the impeller 6. The impeller 6 discharges snow scraped through 14 chutes by high-speed rotation. Reference numeral 7 denotes a connecting shaft, which receives a rotational force from the engine 1 via an appropriate transmission means, and drives the transmission box 11. The speed change box 11 drives the main shaft 10 having auger blades horizontally laid horizontally.

Reference numeral 12 denotes a crushing rotor, and an auger case 8
Are supported by the distal ends of the arms 15 supported on the support shafts 19 on both side walls of the arm. The crushing rotor 12 is equipped with an innumerable number of claws 13 radially in a cylindrical shaft shape. The claw may be a round bar or a sharp excavation claw. Reference numeral 16 denotes a stopper pin.
Insert.

Reference numeral 5 shown in FIG. 2 denotes a driving sprocket provided on the main shaft 10, which rotates a crushing rotor 12 by hanging a chain around the crushing rotor 12.

When the snow is small and the icy snow surface is not formed, the arm 15 is folded upward, fixed by the stopper pin 16 and the chain 18 is removed.
Can be used as a normal snowplow. When the snow cover is higher than the diameter of the auger 9, it is convenient to equip it with 18 chains and use it as a two-stage auger.

[0011]

As described above, even when an icy snowy surface is formed on the surface of the road surface, the crushing rotor of the present invention crushes the auger and advances the auger. It is now possible.
