Description

[Detailed explanation of the invention] When removing snow from a flat road surface, since the auger case is parallel to the road surface, the snow can be shoveled evenly over the entire width of the auger case, allowing for good snow removal. However, in the case of an uneven road surface or a sloping road surface with one side sloping, the auger case may not be parallel to the road surface and may become slanted, or the auger case may rise too much than necessary, causing the entire width of the auger case to scrape snow. This resulted in the disadvantage that snow removal could not be done effectively.

For this reason, the machine is equipped with a correction device that corrects the auger case by hydraulic operation, and the operator activates the correction device each time to correct the auger case. It was difficult for the driver to perform these operations in parallel.

The present invention solves such drawbacks and relates to an automatic correction device for the auger case of a small snow blower, which attempts to automatically correct the auger case according to the road surface condition, and its configuration is illustrated in the attached drawing. The details are as follows.

A machine stand 3 is provided on a crawler frame 2 with crawlers 1 on the left and right sides, an auger case 6 with a snow removal pipe 5 having an auger 4 is integrally provided at the tip of this machine stand 3, and a crawler frame 3 is mounted on the machine stand 3. 1 and auger 4
The engine 7, transmission 8, operating device 9, transmission device, etc. are provided, and the auger case 6 side of the machine platform 3 is slid in the vertical direction with respect to the traveling direction of the machine between the crawler frame 2 and the machine platform 3. A horizontal movement hydraulic cylinder 11 is connected by a vertical movement cylinder 10, and also moves the machine stand 3 left and right between the crawler frame 2 and the machine stand 3 in a direction perpendicular to the direction of movement of the machine.
In a small snow blower connected with It is connected via a command device 13 that gives a command to the horizontal motion hydraulic cylinder 11 in response to the detection by the sensor 12 to automatically operate it.

The horizontal motion sensor 12 shown in the drawing is installed at a position slightly shifted from the center of the top of the auger case 6.

The drawing also shows a case where a vertical motion sensor 14 is provided above the tip of the machine base 3, and the vertical motion sensor 14 and the vertical motion hydraulic cylinder 10 are connected via a command device 15 as well.

It is preferable to use double-acting hydraulic cylinders for the vertical movement hydraulic cylinder 10 and the horizontal movement hydraulic cylinder 11.

Since the present invention is configured as described above, when the machine reaches a slope or a large uneven road surface while traveling, the auger case 6 also tilts as shown by the solid line in FIG. The horizontal motion sensor 13 detects the tilt, and the command device 13
The horizontal movement hydraulic cylinder 11 is automatically operated via the horizontal movement hydraulic cylinder 11 to slide the machine base 3 in one direction in the left and right direction by the amount that the machine base 3 is tilted with respect to the crawler frame 2, thereby moving the auger case 6 to the second Position it parallel to a flat road surface (ground without snow) as shown in the imaginary line shown in the figure. When the auger case 6 becomes parallel to the flat road surface, the horizontal motion sensor 12 does not perform a sensing action, and the command device 13 also does not work, so the horizontal motion hydraulic cylinder 11 does not operate and the auger case 6 becomes flat. It will be located parallel to the road surface.

Furthermore, when a slope or a large uneven road surface is reached during the next run, the horizontal motion sensor 12 senses the degree of inclination and operates the horizontal motion hydraulic cylinder 11 via the command device 13 to trigger the auger. The machine base 3 is slid until the case 6 becomes parallel to a flat road surface.

In this way, the present invention detects the degree of inclination using the horizontal motion sensor 12 when the auger case 6 is not parallel to the flat road surface and is inclined due to the machine reaching a slope or uneven road surface while the machine is traveling. The horizontal movement hydraulic cylinder 11 is operated via the command device 13 to slide the machine base 3 until the auger case 6 is parallel to the flat road surface, so the auger case 6 is always parallel to the flat road surface during snow removal. Because of this, the snow is scraped uniformly across the entire width of the auger case 6, allowing for good snow removal work, and the driver does not have to make any adjustments to the auger case 6 while driving. This provides a compact snow blower that is easy to operate.

Furthermore, if the vertical movement of the auger case 6 is also automatically corrected using the vertical movement hydraulic cylinder 11, a compact snow blower that is even easier to operate can be provided. A switching device is installed to switch to manual mode, and when snow removal is required only on a sloped road surface where only one side is sloping, the device can be switched to manual mode.
In the case of snow removal on sloped roads, uneven roads, flat roads, etc., it has an excellent practical effect in that the snow removal work can be performed efficiently by automation.

[Scope of utility model registration request] A machine base is installed on a crawler frame with crawlers on the left and right sides, and an auger case with a snow removal tube with an auger is installed at the tip of this machine base, and the crawler and auger engines, transmissions, and operations are mounted on this machine base. In addition to providing devices and transmission devices, the crawler frame and the machine base are connected by a hydraulic cylinder for vertical movement that moves the auger case side of the machine base vertically with respect to the direction of movement of the machine. A small snow blower that is connected to the machine base by a horizontal motion hydraulic cylinder that moves the machine base to the left and right in a direction perpendicular to the machine's direction of movement, is equipped with a horizontal motion sensor that detects horizontal movement of the auger case in the direction of movement. This horizontal motion sensor is connected to the horizontal motion hydraulic cylinder via a command device that is installed at an appropriate location on the machine and automatically operates by giving a command to the horizontal motion hydraulic cylinder in response to the detection by the horizontal motion sensor. This is an automatic correction device for the auger case of a small snow blower.
