Description

[Detailed description of the device] [Industrial applications]

The present invention relates to an operating device for a snow blower, which enables a horizontal operation of a snow throwing tube and a deflecting operation of a deflector to be performed with one operating lever using one operating lever.

[Prior art]

Conventionally, the control section is provided with a horizontal rotation adjusting mechanism for horizontally adjusting the base of the snow throwing tube and a deflector turning adjusting mechanism for adjusting the turning angle of the deflector provided at the tip of the snow throwing tube. Snow blowers are known. The horizontal rotation adjusting mechanism is provided with a worm and a worm wheel at the horizontal rotation portion of the base of the snow throwing cylinder, and the worm is rotated via a crank handle and a shaft provided near the control portion of the snow blower. A device in which the snow thrower is rotated in the horizontal direction, or a worm is rotated by a motor, and this is operated by an operation switch provided near the cockpit to rotate the snow thrower in the horizontal direction. There are things that have been done. Further, in the deflector rotation adjusting mechanism, a deflector having a return habit by a spring is connected to an operation lever provided on a control portion by a wire to adjust a rotation angle.

[Problems to be solved by the device]

As described above, since the horizontal rotation adjusting mechanism and the deflector rotation adjusting mechanism are operated by different operating levers or operating levers by the electric switch, they must be operated separately or by using both hands. At this time,
There is a problem in that the operation is troublesome because the operation cannot be performed even if the side clutch and the snow removing section are to be adjusted, and thus it is necessary to disengage the traveling clutch once. The present invention has been made to solve the above problems, and an object of the present invention is to provide an operating device for a snow blower capable of simultaneously operating two rotation adjusting mechanisms with one operating lever.

[Means for Solving the Problems]

In order to achieve the above object, the present invention incorporates the horizontal rotation adjusting mechanism and the deflector rotation adjusting mechanism into one operating device, and horizontally adjusts the horizontal rotation on the top of the operation lever for the deflector rotating adjusting mechanism. Provided with an electric operation switch of the mechanism,
It is characterized in that the operation switch can be operated with one hand holding the operation lever.

[Action]

With the above structure, the deflector rotation angle is adjusted by the rotation of the operation lever to adjust the snow throwing distance, and at the same time,
The other direction (thumb or index finger in the embodiment) holding the operation lever can be used to horizontally rotate the snow throwing cylinder to adjust the snow throwing direction.

【Example】

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, a snow blower indicated by reference numeral 1 is equipped with a crawler type traveling device 3 below a machine base 2, an engine 4 is mounted on a front portion of the machine base 2, and a rear portion of the machine base 2 is mounted. Is provided with a mission 5, a control unit 6, and the like. A hydraulic device (not shown) is provided on a side portion of the engine 4, and a snow removing portion 7 is provided on the front side of the engine 4. The snow removing section 7 includes a lower snow sweeping auger 8, an upper snow sweeping auger 9, and a blower 1.
It consists of 0 and a snow throwing cylinder 11. And the snow removal section 7
Is integrally connected to the engine 4 mounting portion, receives power from the engine 4, and can move up and down together with the engine portion via a hydraulic cylinder (not shown) and the like as shown by phantom lines. There is. The snow throwing cylinder 11 is configured to rotate horizontally in a horizontal rotating portion 12, and the horizontal rotation driving portion 13 is provided with a worm wheel (not shown) and a worm that meshes with the worm wheel. The worm is driven by an electric motor 21 described later. Further, the deflector 14 of the snow throwing tube 11 is given a habit of returning by springs 15 arranged in two steps, and one end of an operation wire 17 is connected to a rotation angle adjusting link 16 provided on a side portion, and the other end is connected. Is connected to an operation lever 18 provided on the control section 6. Operating lever
An operating switch 19 shown in FIG. 2 is provided on the top of the grip 18a of the 18 and the operating switch 19 and the horizontal rotating portion are provided.
Lead wires 20 connect between the 13 members. The operation switch 19 has the habit of returning to the neutral position by rotating forward and backward or left and right with the upright state as the neutral position, and as shown in FIG. 3, the operation switch 19, the motor 21, and the connector 21a. Between battery 22 or standby power source
A relay box 24, a connector 24a, reed switches 23L, 23R, etc. are provided with 22a as a power source.
When, for example, is tilted to the left, the reed switch 23L is energized to normally rotate the motor 21 via the relay box 24, and the snow throwing cylinder 11 is rotated leftward in the horizontal rotation unit 12 via the worm and worm wheel. When the operation switch 19 is tilted to the right, the reed switch 23R is energized to reverse the motor 21 via the relay box 24 and rotate the snow throwing cylinder 11 to the right. Each rotation range is the operation switch 19
It is designed to be proportional to the operation time of. In the snow removing machine having such a configuration, when adjusting the snow throwing distance and the snow throwing angle from the snow throwing cylinder 11 during the snow removing work, the operation lever 18 is operated to change the angle of the deflector 14.
When changing the snow throwing direction of the snow throw tube 11, the operation switch 19 is tilted with the thumb or forefinger of the hand holding the grip 18a to turn the snow throw tube 11 left and right. Both of these operations can be performed with one hand, and therefore, the other clutch can be used to operate the side clutch and the snow removal section 7 up and down. The operation switch 19 provided on the operation lever 18 has a fourth
19a in the drawing and 19b in FIG. 5 may be used.
Any of them can be operated in the same manner as the operation switch 19 of the above embodiment.

[Effect of device]

As described above, according to the operation device of the snow blower of the present invention, the horizontal rotation adjustment of the snow throwing cylinder and the angle adjustment of the deflector can be performed with one operating lever and with one hand holding the lever. As a result, one can freely perform two adjustment operations, one for adjusting the horizontal rotation of the snow throw cylinder and the other for adjusting the angle of the deflector, and the other hand to operate the side clutch, handle, snow throw, etc. , It is possible to freely adjust the snow throw without stopping the snow blower. In addition, the structure is compact, and no erroneous operation occurs.
