Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a device for adjusting the direction of snow removal in a simple snow remover that can reliably and easily change the direction of snow removal.

[Problems to be solved by conventional techniques and ideas]

Conventional compact snow blowers, which are commonly used for sidewalks, highways, and homes, rotate an auger mounted on a shaft at the front of the machine that runs on a track, and scrape the snow in front of it into the auger case. The snow is collected in the center of the auger case by the action of the auger, and the snow collected in the center is sent to the blower adjacent to the rear of the auger via the snow introduction path, and the rotation of this blower causes the snow to be bounced upward. Raise,
Snow is removed through a snow removal tube installed upright on the machine body. This type of small snow blower has a track running device and an auger that provide a corresponding amount of driving thrust and snow removal ability, but on the other hand, it has a large torque. The drawback is that the snow blower is very heavy and expensive due to the need for a prime mover.

[Means for solving problems]

The present invention is intended to solve these drawbacks, and its structure will be described in detail with reference to the accompanying drawings as follows.

For example, a flexible wire may be connected to the handlebar, and the point is that the slope of the snow removal plate 8 can be adjusted from side to side.

[Effect of idea]

As described above, the present invention installs a bearing plate between the front edges of the tops of the left and right side wall plates of the snow introduction case, extends the rear wall plate upward to form a snow conveyance path, and separates this snow conveyance path. The lower part of the folded rear wall of the snow removal plate divided into sections is attached to the rear wall plate by a fulcrum shaft, and the opposing position of the snow removal plate with the bent front wall is attached to the bearing plate by the fulcrum shaft. Since the snow removal plate is installed so that it can be tilted left and right, the snow removal rotor is rotated downward by the prime mover, and when the snow removal plate is tilted and fixed in either the left or right snow removal direction and the aircraft is pushed forward by hand, the snow in front is removed by the snow removal rotor. The snow is shoved into the introduction case and thrown upwards under centrifugal force by the action of the rear wall plate, and the thrown snow is thrown away by a snow removal plate that is slanted in either the left or right snow removal direction. The snow passes through the snow transport path provided in the state and is blown to either the left or right side of the aircraft.

Moreover, the left and right slope of the snow removal board is achieved by pivoting the upper part of the folded wall of the snow removal board to a movable horizontal board that moves left and right, and attaching the tip of the lever to a shaft protruding from the middle of the back of this moving horizontal board. The lower part of this lever is fixed to the tip of an operating rod that is movable back and forth with respect to a support provided on the upper part of the machine, and a handle rod is connected to the base of the operating rod. Since the handle rod is engaged with the handle rod guide section provided on the support handle, all you have to do is tilt the handle rod to the left or right and rotate the operating rod, making it very easy to operate. At the same time, the direction of snow removal can also be adjusted, making it extremely practical.

In addition, a bearing plate is installed between the front edges of the tops of the left and right side wall plates of the snow introduction case, so the bearing plate shields the area between the top of the snow introduction case and the lower front edge of the snow removal plate, so the snow in front is removed from the snow introduction case. The snow is surely raked in from the front without scattering from the front edge of the top of the snow introduction case, and the snow is certainly removed from the top surface of the snow introduction case, and the snow removal plate located on the top surface guides the snow more accurately. Snow will be removed.

Moreover, since the snow removal plate is installed between the bearing plate and the rear wall plate, it is stronger and has enough rigidity to withstand the snow removal force, so it can perform the change function more reliably. .

Furthermore, since the handle rod that adjusts the inclination angle of the snow removal board is engaged with the handle rod guide provided on the support handle, one hand can be extended while grasping the support handle and pushing the snow removal plate forward by hand. Since you can adjust the handle rod with just one
This makes it easier and more accurate to use.

In addition, since the structure is simple, it can be made smaller and lighter, and it can be manufactured at a lower cost, making it suitable for mass production and requiring a smaller torque motor than conventional small snow blowers.

As described above, the present invention provides a snow removal direction adjusting device for a simple snow blower that can reliably and easily change the snow removal direction, is very economical, and has excellent practical effects.
