Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a snow blower that is movable by wheels pivotally supported at the bottom of the snow blower body (hereinafter simply referred to as the machine body).

This type of snow blower is easy to handle, so it is used regardless of how much snow there is, and it is often used by people who are powerless, such as housewives. Therefore,
It is desirable for this type of snow blower to be able to be easily moved by even a weak person regardless of whether there is snow or not. However, when there is no snow or very little snow, the machine can be easily moved using the wheels pivoted at the bottom of the machine, but when there is snow, the machine becomes buried in the snow and creates resistance when moving. This makes it difficult to move the snowplow.

The present invention has been made to deal with this problem,
The purpose of this is to place the skis in an appropriate position below the main body of this type of snow blower in relation to the wheels, and to move this type of snow blower regardless of whether there is snow or not. make it easy to
Another object is to be able to change the snow removal position as desired depending on the snow depth, snow quality, etc.

Hereinafter, the present invention will be explained based on the drawings. FIG. 1 shows an example of a snow remover according to the present invention. A machine body 11 of this snow blower is provided with plates 12 projecting downward on both the left and right sides thereof, and a pair of left and right wheels 21 can be rotated by a left and right insertion bolt 13a and a nut 13b inserted through the plate 12. It is pivoted on. Further, an engine (not shown) covered by a cover 14 is mounted on the main body 11 of the machine. On the other hand, an auger 22 driven by an engine is rotatably supported at the front of the machine body 11, and a plurality of guide plates 24 are attached to the front of the rear upper wall 23a of the auger housing 23. There is. Each guide plate 24 is attached so as to be tiltable in the left-right direction, and is tilted by rotating a lever 25 extending rearward from the cover 14 to determine the direction in which the snow raked by the auger 22 is thrown. In addition, the machine body 1
A handle 26 that slopes upward toward the rear is attached to the rear portion of the vehicle. This handle 26
moves the front part of the machine body 11 up and down to appropriately position the auger 22 with respect to the snow, and also functions as a handle when moving the snow blower. Note that the reference numeral 27 indicates a recoil starter for starting the engine.

Thus, skis 31 extending in the left-right direction of the machine body 11 are attached to the lower part of the snow blower. As shown in FIGS. 1 and 2, this ski 31 has a pair of mounting brackets 32 provided on the left and right sides of the center, and a connecting bracket 33 provided on one side of the front part of the ski 31. It is attached to the machine body 11 via a bracket 32. Further, the front and rear portions of the ski 31 are formed into a curved shape that bends upward, and the wheels 21 are located near the mounting bracket 32 of the ski 31.
A pair of openings 31a through which the lower part of the opening 31a faces downward.
is provided. The ski 31 is attached to each wheel 21 at each mounting bracket 32 by an insertion bolt 13a and a nut 13b, so that the ski 31 can swing back and forth about the insertion bolt 13a. In this state, the lower part of each wheel 21 is connected to each opening 31a of the ski 31.
The sliding surface of the ski 31 is located above the ground contact surface of each wheel 21.
Further, the snow remover is provided with means for regulating the back and forth swinging of the skis 31 and fixing the slope thereof. As shown in FIGS. 1, 3, and 4, this fixing means includes a rotation bolt 34 rotatably attached to the lower front part of the plate 12 provided on one side of the machine body 11; It consists of a tightening nut 35 for tightening the rotation bolt 34, and a connecting rod 36 inserted into an insertion hole 34a provided perpendicular to the rotation bolt 34. This connecting rod 3
The lower end of the ski 6 is rotatably connected to a connecting bracket 33 provided at the front of the ski 31. As a result, when the tightening nut 35 is screwed forward, the tightening force causes the connecting rod 3 to tighten against the rotating bolt 34.
6 is tightened, the back and forth rocking of the ski 31 is restricted, and the ski 31 is fixed in a predetermined inclined state. Further, when the tightening nut 35 is screwed back, its tightening force disappears and the connecting rod 36 becomes movable, thereby allowing the ski 31 to swing back and forth.

In the snow blower constructed in this manner, after the ski 31 is fixed in a substantially horizontal state by the fixing means, the handle 26 is pushed down to rotate the auger 22 and the auger housing 23 upward, and then the handle 26 is pressed down. It is pushed in the front and back direction through the wheels 21 and moved to the destination of snow removal. At the snow removal destination, the handle 26 is moved up and down to position the auger 22 at an appropriate depth of snow, thereby efficiently removing snow.

By the way, in the snow blower, the machine body 11
Since the skis 31 are attached to the bottom of the skis 31 and the wheels 21 protrude downwards from the openings 31a provided in the skis 31, it is possible to use the skis 31 when there is no snow or when the amount of snow is very small before reaching the snow removal destination. The machine body 11 can be moved using both wheels 21, and when there is snow, skis 31 can be used to prevent the machine body 11 from being buried in the snow, and the machine body 11 can be moved while sliding on the snow. Therefore,
Regardless of whether or not there is snow on the way to the snow removal destination,
You can easily move the snow blower.

In addition, in this snow blower, even when there is a large amount of snow, the skis 31 that evenly contact the snow cover prevent it from being buried in the snow, so of course the snow blower can be easily moved. Even at the destination, by adjusting the inclination of the ski 31 using the fixing means, the auger 22 can be positioned at an appropriate depth of snow, thereby further increasing snow removal efficiency.

Furthermore, if the skis 31 are attached to each wheel 21 as in this embodiment, even if the skis 31 swing back and forth, the amount of protrusion of the wheels 21 from the openings 31a provided in the skis 31 will be constant. The area of the opening 31a is minimized, and compared to the case where the skis 31 are mounted at a position apart from each wheel 21, there is an advantage that the snow contact area can be made wider even with the skis 31 of the same size.

In addition, since this snow blower is provided with a means for fixing the skis 31, the tightening nut 35 is screwed in to restrict the back and forth rocking of the skis 31 and fix the skis 31 in a substantially horizontal state. If this is done, there will be no problem when moving the snow blower using its wheels. In addition, the fixing means for the skis 31 can adjust and fix the front and rear inclinations of the skis 31, so the inclinations of the skis 31 can be adjusted according to the quality of the snow, and the skis 31 can be adjusted in place during snow removal. The amount of the board 31 buried in the snow can be reduced. For example, when the snow is soft such as fresh snow, the amount of burying of the ski 31 is reduced by adjusting the inclination of the ski 31 so that the tip of the ski 31 points slightly upward.

It should be noted that the above embodiment is one embodiment of the present invention, and the present invention is not limited only to this embodiment. The present invention can be implemented in various types of snow removers that are movable in the front and rear directions using wheels that are pivotally supported on the left and right sides of the lower part of the machine body.

As explained above, the present invention provides skis that are attached to the lower part of the body of the snow blower of the various types described above so as to be able to swing around an axis in the left and right directions, and the wheels protrude downward from openings provided in the skis. let me,
Another feature of the structure is that a fixing means for fixing the skis in any inclined state is provided between the snow blower body and the snow blower body. Therefore, according to the present invention, the wheels and the skis reasonably arranged in relation to the wheels make it possible to easily move the snow blower by means of the wheels when there is no snow or when there is very little snow. Even when there is a lot of snow, the machine body can be floated on the snow using skis, making it easy to move the machine, and the snow removal position can be adjusted as desired depending on the snow depth and snow quality. Snow removal efficiency can be increased by changing the snow removal efficiency.
