Description

Description: TECHNICAL FIELD The present invention relates to a riding snow blower that allows an operator to get on and perform snow removal work.

(Prior Art) In general, a snowplow is provided with a snowplow including an auger at the front of the fuselage, and while the body is moved forward by a crawler traveling device or the like, the auger of the snowplow rotates the snow at the center of the front of the body. The required snow removal operation is performed by collecting the collected snow and sucking the collected snow with a blower and discharging the collected snow from the shooter.

By the way, as a small snowplow, a type called a walk-behind, in which a worker walks behind the body while operating to work, is exclusively used.

However, the walk-behind type snow remover has a problem that the burden on the worker is large because the worker must walk on the snow.

Therefore, it is conceivable to develop a small riding type snow plow in which a worker can get on and work.

On the other hand, in the field of construction machines such as power shovels, there are already those of the same size as small-sized riding types.

Therefore, it is conceivable to apply a small riding type that already exists in the construction machine field to a snow blower.

(Problems to be Solved by the Invention) However, while construction machines usually work while the body is stopped, snow removers perform snow removal while traveling on rough roads on snow. Requires high running stability. Therefore, high running stability cannot be ensured simply by applying a small-sized riding construction machine to a snow blower, and it has been difficult to put the snow removing machine to practical use unless such a problem is solved.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a riding snow plow that can ensure high running stability and allow a worker to easily perform a snow removing operation in a stable posture. To provide.

(Means for Solving the Problems) In order to achieve the above object, the present invention provides a traveling device having wheels supported on both left and right ends of a front axle and a rear axle which are laid across a pair of left and right arms. In the riding snow blower having a snow removal section at a front portion of a body traveling by a vehicle and rotatably supporting the body around a front axle and fixing a seat to the pair of left and right arms, the front axle and the rear An engine is arranged between axles, a transmission is arranged in front of the engine and between front wheels, and the seat is arranged so as to cover an upper part of the engine.

(Operation) According to the present invention, since the heavy engine is disposed between the front axle and the rear axle, the center of gravity of the airframe is lower than that of the conventional one, thereby increasing the running stability of the snow blower. Can be As a result, even when the worker gets on the snow plow and travels on a bad road on snow while performing the snow removal work, the worker can easily perform the snow removal work in a stable posture.

Further, since the transmission is arranged in front of the engine, the position of the seat (that is, the riding position of the worker) can be suppressed lower than when the engine and the transmission are arranged vertically, and the center of gravity of the body is The running stability of the snow blower can be further increased by further lowering.

Furthermore, since the engine is disposed between the front axle and the rear axle, interference between the front and rear axles and the engine can be prevented even when the entire body is rotated around the front axle, and the rotation as a center of rotation is achieved. The length from the front axle to the rear end of the engine, which is the rear end of the rotation, can be reduced, and the rotation angle of the body can be sufficiently secured. Since the upper part of the engine is covered by the seat, the engine, which is the rear end portion of the rotation, does not have a risk of coming into contact with another obstacle due to the vertical swing, so that the worker can concentrate on the work.

In addition, since the snow removal part and the engine are arranged separately before and after the front axle, which is the center of rotation of the body, the driving force for raising and lowering the snow removal part can be suppressed.

Embodiment An embodiment of the present invention will be described below with reference to the accompanying drawings.
