JP3870386B2 - Snow-crushing device for ice-like snow surface - Google Patents

Description

[0001]
[Industrial application fields]
The present invention relates to a configuration of a crushing rotor that is an auxiliary device corresponding to an icy snow surface of a snowplow having a scraping auger at a front portion of a self-propelled aircraft.
[0002]
[Prior art]
In the snowy area, especially near spring, the surface layer of the ground is frozen. The scraper that forms the bottom surface of the auger housing proceeds while being crushed on this icy snow surface, but when the icy layer is hard or thick, the scraper travels up and down. Japanese Utility Model Laid-Open No. 3-72930 is known as a method of crushing a freezing plate by swinging a bottom scraper of a housing up and down.
[0003]
[Problems to be solved by the invention]
In the configuration in which the bottom scraper of the auger housing is swung up and down as described above, the crushing effect is reduced when the freezing plate is thick, and at the same time, when the self-propelled machine runs, intermittent vibration occurs due to the reaction force of the scraper, making it impossible to run. There was a problem.
[0004]
[Means for Solving the Problems]
In order to solve the above problems, a snow remover in which an auger that scrapes snow into an auger case attached to the front part of a self-propelled machine body and scrapes it into the snow discharge part is rotatably provided. A crushing rotor having a cylindrical shaft for crushing an icy snow surface and equipped with countless claws radially on the outer peripheral surface is positioned, and the crushing rotor can be rotated up and down, and is positioned below to dispose the icy snow surface. as well as a possible disruption is obtained by providing glacial snow crushing device snowplow which was characterized by available der Rukoto as two-stage auger by rotating by positioning the top.
[0005]
[Action]
The crushing rotor provided at the lower front part of the present invention for scraping snow is forcibly crushing the icy snow surface of the surface of the road surface and supplying it to the auger, and the scraper part of the auger housing may be caught on the surface. Snow removal work is now possible smoothly and continuously.
Further, in the case of fresh snow having no icy snow surface on the road surface, the crushing rotor is rotated upward to be folded and fixed. When the snow layer is thick, it may be driven and used as a two-stage auger rotor.

【Example】
FIG. 1 for explaining the configuration based on the drawings in which the present invention is implemented is a side view in which the present invention is implemented, and shows the main part in cross section. FIG. 2 is a front view of the main part. Reference numeral 1 denotes an engine placed on the upper part of the main frame 4, and 3 denotes a crawler, which is disposed on both sides of the main frame 4. Reference numeral 2 denotes a handle that is obliquely provided behind the main frame 4.
[0007]
Reference numeral 8 denotes an auger case provided in front of the main frame 4 and supports the auger 9 so as to be orthogonal to the traveling direction. The auger 8 scrapes snow from the left and right toward the center and sends it to the 6 impeller. The impeller 6 discharges snow that has been scraped through 14 chutes by high-speed rotation. Reference numeral 7 denotes a connecting shaft, which receives rotational force from the engine 1 through appropriate transmission means, and drives 11 transmission boxes. The transmission box 11 drives a main shaft 10 having auger blades mounted horizontally.
[0008]
Reference numeral 12 denotes a crushing rotor, which is supported by the tips of the arms 15 supported by the support shafts 19 on both side walls of the auger case 8. The crushing rotor 12 has a cylindrical shaft shape and is equipped with countless claws 13 radially. The claw may be a round bar or a drilling claw with a sharp tip. Reference numeral 16 denotes a stopper pin, which is inserted into the hole 17 of each auger case 8 at a position (shown by a solid line) for crushing the icy snow surface and a position folded upward.
[0009]
Reference numeral 5 shown in FIG. 2 denotes a drive sprocket provided on the main shaft 10, and the crushing rotor 12 is rotated by hanging a chain around the crushing rotor 12.
[0010]
In addition, when there is little snow accumulation and an icy snow surface is not formed, if the arm 15 is folded upward and fixed by the stopper pin 16 and the 18 chain is removed, it can be used as a normal snow remover. Also, when the snow cover is higher than the diameter of the auger 9, it is convenient to use 18 chains and use it as a two-stage auger.
[0011]
【The invention's effect】
Since it is configured as described above, even when an icy snow surface is formed on the surface of the road surface, the auger is crushed by the crushing rotor of the present invention, and the auger is pushed forward. It is.
