Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a self-propelled snow blower in which a snow removal section is connected to the front part of a traveling main body.

[Conventional technology]

Conventionally, for snow removal work in snow removal areas, self-propelled snow removers with a snow removal section connected to the front part of a traveling main body have been used. machine is known. In other words, in the above-mentioned self-propelled snow blower, the traveling body and the snow removal section equipped with a snow collecting screw and a snow blower are connected by a support frame so as to be able to move up and down and roll left and right, and the engine mounted on the main body Part of the engine rotation rotates the blower in the snow removal section via a belt tension clutch, etc., and also rotates the snow collecting screw via a reduction gear.Furthermore, the other part of the engine rotation is linked to the main clutch, and the transmission The drive wheels of the running cover are rotated through the drive wheel.

[The problem that the idea aims to solve]

However, conventional self-propelled snow blowers have the ability to adjust the height of the snow removal section connected to the main body according to road conditions and the condition of the snow removal section, or to roll the snow removal section from side to side. Since it does not have a rotating mechanism, there is a problem that snow removal work cannot be performed smoothly when snow removal work is performed along a curve or when changing direction during snow removal work.

The present invention was developed to solve the above-mentioned problems, and is equipped with a vertical height adjustment function, a rolling function, and a left-right rotation function in the snow removal section of a self-propelled snow blower, so that it can be used on roads during snow removal work. It is an object of the present invention to provide a self-propelled snow blower that is designed to improve workability, such as being able to work smoothly depending on the situation.

[Means to solve the problem]

In order to achieve this purpose, the self-propelled snow blower according to the present invention has a structure in which a snow removal section that receives power from the main body is connected to the front part of the main body for walking so that it can move vertically and roll horizontally. In the snow blower, the rear central part of the snow removal section is pivotably supported on the front part of the frame of the main body so as to be rotatable vertically and horizontally, and a cylinder is provided between the main body frame and the snow removal section to control the vertical and horizontal rotation of the snow removal section. It is characterized by having a mechanism.

[Effect]

Therefore, in a self-propelled snow blower configured as described above, during snow removal work, the snow removal section can be moved up and down and rolled left and right according to the undulations and curves of the road, and the snow removal section can also be moved up and down independently. By rotating left and right, smooth snow removal work is possible in any situation.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a partially cutaway side view showing an embodiment of a self-propelled snow blower according to the present invention, and FIG. 2 is a plan view showing a connecting portion between the main body and the snow removing section according to the present invention.
In the figure, reference numeral 1 denotes a self-propelled snow remover that includes a main body 2 and a snow removal section 3, and the main body 2 and the snow removal section 3 are connected by a connection section 4. An engine 6 is mounted on the body frame 5 of the main body 2, and a transmission 7 is installed at the rear of the body frame 5. An output shaft 8 of the transmission 7 is connected to the body frame 5. frame 5
The rear drive wheels 1 of the running cover 9 are arranged on the left and right sides of the
0 is installed. Further, on the vehicle body frame 5, an operation panel 1 equipped with various operation levers 11 is provided.
2 is installed, and part of the rotation of the engine 6 is linked to a main clutch (not shown) and transmitted to the drive wheels 10 of the running cover 9 via the transmission 7, and the other part of the engine rotation is , a belt tension clutch 13, etc., to a drive shaft 15 that rotates the blower and snow collecting screw 14 of the snow removal section 3. The drive shaft 15 is composed of a main body drive shaft 17 and a snow removal part driven shaft 18 which are connected by a universal joint 16 or the like at the connection part 4 between the main body 2 and the snow removal part 3.

On the other hand, a rolling bush 19 is installed on the rear central connection side of the snow removal section 3, and a hit part 20 having a U-shaped cross section can freely rotate around the outer periphery of the snow removal section side driven shaft 18 via the rolling bush 19. The hit portion 20 having a U-shaped cross section and a connecting member 21 attached to the front of the vehicle body frame 5 are connected by a connecting pin 22 so as to be rotatable left and right. Furthermore, a left-right rotation cylinder 23 is installed between the hit portion 20 of the snow removal section 3 and the vehicle body frame 55 of the main body 2 to rotate the snow removal section 3 left and right using the connecting pin 22 as a fulcrum. , further, the body frame 5 of the main body 2
A vertical cylinder 25 is installed between the main body 2 and the support frame 24 of the left and right running covers 9 to adjust the height of the front of the main body 2 in the vertical direction using the output shaft 8 of the transmission 7 as a fulcrum. ing. In the figure, 26 is a chute of the snow removal section 3, and 27 and 28 are bearings of the drive shaft 15.

In such a configuration, when snow removal is performed by operating each operating lever 11 on the operation panel 12, the vertical height of the snow removal section 3 may be adjusted while driving according to road conditions or curves, or the direction may be changed. At times, the snow removal section 3 can be rotated left and right or rolled while performing snow removal work smoothly.

3 and 4 are a side view and a plan view of the main parts of another embodiment of the self-propelled snow blower according to this invention, in which the vehicle body frame 5 and the running cover 9 do not move up and down, and the vehicle body Only the snow removal section 3 connected to the front part of the frame 5 can be moved up and down, rotated left and right, and rolled.

Here, in front of the main body 2, the vehicle body frame 5
A lateral connecting rod 30 is rotatably attached around a pivot point 31 between the arms 5a, 5a extending from both sides of the body frame 5. The connecting rod 30 is the pivot point 3
A cylinder 25 that rotates around 1 is installed. Furthermore, a hitch portion 20 attached to the rear center portion of the snow removing portion 3 is connected to the center portion of the connecting rod 30 attached to the front side of the main body 2 by a connecting pin 22 so as to be rotatable left and right. hitch part 2
0 and the connecting rod 30 on the main body side, there is a connecting pin 2.
A left-right rotation cylinder 23 is installed to rotate the snow removal section 3 left and right using the snow removal section 2 as a fulcrum.

Therefore, when performing snow removal work using the self-propelled snow blower configured in this way, the snow removal section 3 can be controlled depending on the situation by operating each control lever 11 on the operation panel 12 as described above. It can be rotated left and right, moved up and down, or rolled to perform smooth work.

[Effect of idea]

As explained in detail above, according to the self-propelled snow blower of the present invention, the snow removal section connected to the front part of the main body
In addition to the vertical height adjustment function and the rolling function, it also has a left and right rotation function, so you can smoothly remove snow according to the situation, such as when removing snow along a curve or changing direction while removing snow. This greatly improves work performance.
