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. It is connected by a hydraulic cylinder 10 for vertical movement, and also has a crawler frame 1.
and a machine base 3 are connected by a horizontal motion hydraulic cylinder 11 that allows the machine base 3 to slide left and right in a direction orthogonal to the direction of movement of the machine. A vertical motion sensor 12 is installed at an appropriate location on the machine, and this vertical motion sensor 12 and horizontal motion hydraulic cylinder 10 are connected to the vertical motion sensor 12.
This hydraulic cylinder 10 for vertical movement
A command device 13 that automatically operates by giving a command to the
Connect via.

The vertical motion sensor 12 shown in the drawing is installed above the tip of the machine base 3.

Further, in the drawing, a horizontal motion sensor 14 is provided on the top of the auger case 6, and the horizontal motion sensor 14 and the hydraulic cylinder 11 for horizontal motion are also connected to the command device 1.
The figure shows a case where the connection is made through 5.

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 large uneven road surface or a rough road while traveling, the auger case 6 also rises more than necessary as shown by the solid line and imaginary line in Fig. 2. When the auger case 6 moves up and down, the up and down movement of the auger case 6 is detected by the up and down movement sensor 12, and the up and down movement hydraulic cylinder 10 is automatically operated via the command device 13 to move the machine base 3 to the crawler frame. The auger case 6 is moved against a flat road surface (ground without snow) as shown by the solid line in Fig. 2 by sliding the machine base 3 vertically by the part that is rising or falling relative to 2. It is installed in a preset location that is easiest to remove snow from.

When the auger case 6 is at the position where it is easiest to remove snow, the vertical motion sensor 12 does not perform a sensing action and the command device 13 also does not work.
The vertical movement hydraulic cylinder 10 is also not operated, and the auger case 6 is at the position where it is easiest to remove snow from the flat road surface.

Further, when the next time a rough road or a large uneven road surface is reached, the vertical movement sensor 12 senses the degree of vertical movement, and the vertical movement hydraulic cylinder 10 is operated via the command device 13 to move the auger case 6. The machine base 3 is slid to the position where it is easiest to remove snow.

As described above, in the present invention, when the auger case 6 moves away from the position where it is easiest to remove snow from a flat road surface due to a rough road or uneven road surface while the machine is traveling, the vertical movement sensor 12 detects the vertical degree. , and operates the hydraulic cylinder 10 for vertical movement via the command device 13 to move the machine base 3 to the position where the auger case 6 is easiest to remove snow from the flat road surface. Since it is always in the position where it is easiest to remove snow from the flat road surface, snow is shoveled evenly across the entire width of the auger case 6, allowing for good snow removal work and allowing the driver to use the auger while driving. Since there is no need to make any modifications to Case 6, a compact snow blower that is easier to operate is provided.

Furthermore, if the horizontal movement of the auger case 6 is also automatically corrected using the horizontal movement hydraulic cylinder 11, a compact snow blower that is even easier to operate can be provided. It is equipped with a switching device that allows you to switch to manual when removing snow only from flat roads, and automatically when removing snow from rough, uneven, or flat roads, allowing for highly efficient snow removal work. This has practical effects.
