[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a snow blower, and more specifically, it is equipped with a traveling mechanism, a snow removal mechanism, and a steering handle, and is capable of walking while grasping the steering handle. The present invention relates to the manner in which clutch levers for traveling and for snow removal are installed in a snow blower operated by an operator.

[Prior art]

Snow blower 1 of conventional structure shown in Fig. 3 and Fig. 4
comprises a snow removal mechanism section A consisting of an auger 2, a snow collection guide plate 3, a snow throwing chute 4, etc., and a traveling mechanism section B consisting of a pair of left and right track type traveling devices 5, 5. . Furthermore, this snow blower 1 is provided with a pair of left and right steering handles 6, 6, and one of the steering handles 6 is provided with a clutch lever 7 for snow removal. This lever 7 is used to engage and engage a clutch (not shown) interposed between an engine 8 as a drive source and the snow removal mechanism section B. Also, the operation table 9 of the snow blower 1
A speed change lever 10 for driving is disposed on the vehicle. When performing snow removal work using the snow blower 1, shift the gear lever 10 to the snow remover 1.
while moving the steering handles 6, 6 forward.
When the operator grasps the snow removal clutch lever 7 while carrying out a steering operation by an operator walking with the snow removal machine 1, the snow removal mechanism section A is operated and snow removal is performed continuously. It can be done.

By the way, when performing snow removal work with the snow blower 1, the operator operates the steering handles 6, 6.
When the snow removal clutch lever 7 is released and the operation of the snow removal mechanism section A is stopped, the gear shift lever 10 is still shifted, so the snow removal machine 1 is not operated by the operator. There was an inconvenience that the vehicle continued to run independently without any direction control. In order to deal with such inconveniences, the other steering handle 6 is provided with a clutch operation lever (traveling clutch lever) interposed between the engine 8 and the traveling mechanism section B, so that it can be used during snow removal work. There is also a snow blower configured so that the operator holds the left and right steering handles 6, 6, as well as a clutch lever for snow removal and a clutch lever for traveling. However, with such snow blowers, the operator must constantly hold both clutch levers while removing snow, which can easily cause fatigue, and the operator must always hold both steering handles with both hands. Therefore, the operator's working posture with respect to the snow blower 1 is limited, and the snow blower 1
It was difficult to manage.

[Purpose of invention]

In view of the above-mentioned circumstances, it is an object of the present invention to provide a snow blower that can prevent the snow blower from continuing to run independently away from the operator and is easy to maneuver during snow removal work.

[Structure of the idea]

Therefore, in the present invention, a snow removal clutch lever of a snow removal mechanism, which has a loop shape that overlaps with the steering handle, is swingably supported on the steering handle, which has a loop shape, through a pin. A tension spring is moored between the snow removal clutch lever in such a manner that it crosses the axis of the pin when the snow removal clutch lever swings between the operating position and the non-operation position, and the snow removal clutch lever is connected to the steering handle. A traveling clutch lever of the traveling mechanism is disposed within a swing range of the clutch lever for driving, and when the clutch lever for snow removal is operated, the clutch lever for traveling is pressed by the clutch lever for snow removal, The above object is achieved by operating the traveling clutch lever.

It is structured as follows. Further, the gripping portion 30b includes a left gripping portion 30c and a right gripping portion 30d that extend back and forth,
It consists of a front side grip part 30e extending left and right, and has a substantially U-shape that is open to the front. A loop clutch lever 40 for snow removal is disposed in a lower region of the grip portion 30b of the steering loop handle 30. This snow removal loop clutch lever 4
0 (hereinafter referred to as snow removal lever 40) is
It is composed of a bent pipe material consisting of a left grip part 40a, a right grip part 40b, and a front grip part 40c, and its outer shape is approximately U-shaped with an open front, and the above-mentioned steering loop It is formed so as to entirely overlap the grip portion 30b of the handle 30. Further, the snow removal lever 40 is swingably supported by the steering loop handle 30 via pins 41, 41. As clearly shown in FIG. 2, an operating wire 50 from a clutch (not shown) interposed between the snow removal mechanism A and the engine (not shown) is moored to the snow removal lever 40. , in the normal state, the snow removal lever 40 is
By being pulled by a clutch (not shown) via the operating wire 50, the clutch is moved to a disconnected position away from the grip portion 30b of the steering loop handle 30, as shown in FIG. 2a, in other words, a snow removal mechanism non-operating position. It is occupied by In addition, the above snow removal lever 40
is equipped with a stopper mechanism (not shown),
It is configured not to swing downward from the non-operating position. Furthermore, the steering loop handle 3

is moored so as to straddle the pin 41 as a point of consideration. The action of this spring 60 will be explained in detail later. On the other hand, a travel clutch lever 70 (hereinafter referred to as travel lever 70) is swingably supported on the left grip portion 30b of the steering loop handle 30 via a pin 71. An operating wire (not shown) extending from a clutch (not shown) interposed between the traveling mechanism section B and the engine (not shown) is moored to the travel lever 70, and in normal state, the travel lever 70
0 is pulled by the clutch via the operating wire, thereby occupying the clutch disengaged position shown in FIG. 2a, in other words, the traveling mechanism section non-operating position. On the other hand, reference numeral 80 in the figure is an operation table, and a gear shift lever 81 is disposed on the table 80. In the figure, reference numeral 82 is a snow throwing direction adjustment handle, and reference numeral 83 is a shoot cap operating lever.

Hereinafter, the actual snow removal work performed by the snow removal machine 100 according to the present invention will be explained step by step. To move the snow blower 100 to the point where snow removal work is to be performed, the operator first starts the engine, shifts the gear shift lever 81 to the forward position, and then moves the travel lever 70 to the steering loop handle 30. By gripping the gripping portion 30b, the traveling lever 70 is swung from the traveling mechanism non-operating position to the traveling mechanism operating position (see FIG. 2b). As a result, the clutch between the traveling mechanism section B and the engine becomes connected, and the traveling mechanism section B operates.
The snow blower 100 starts moving forward. Thereafter, the operator grasps the steering handle 30 and performs a steering operation to cause the snow blower 100 to travel to a desired point, and then releases the travel lever 70 at that point to stop the snow remover 100. To actually perform snow removal work from the above point, the operator only has to pull up the snow removal lever 40 and grasp the lever 40 together with the grip portion 30b of the steering lever 30. As a result, the snow removal lever 40 swings from the snow removal mechanism non-operating position to the snow removal mechanism operation position shown in FIG. 2b, the clutch between the snow removal mechanism A and the engine becomes connected, and the auger 2 etc. start working. Also, when the snow removal lever 40 is pulled up,
As shown in FIG. 2b, when the snow removal lever 40 comes into contact with the gripping surface 70a of the travel lever 70 and pushes it up, the travel lever 70 is placed in the travel mechanism operating position, and as described above, the snow removal 1 starts moving forward. In this manner, by operating the snow removal lever 40, both the snow removal mechanism section A and the traveling mechanism section start operating, and snow removal work is performed continuously. At this time, as described above, the grip portion 30b of the steering loop handle 30 and the snow removal lever 4
0, since both of them form a substantially U-shape and are arranged so as to overlap, the snow removal lever 40 can be gripped together with the grip portion 30b at any location on the grip portion 30b. , the degree of freedom of the operator's steering work position is increased, and snow removal work can be performed in a comfortable position.

By the way, when operating the snow removal lever 40,
When the snow removal lever 40 is at or near the operating position of the snow removal mechanism, as shown in FIG. 2b,
The tension spring 60 is located above the pin 41, which is the fulcrum of the snow removal lever 40, in the figure. As a result, the force of the tension spring 60 is applied to the snow removal lever 40.
This will act in the direction of pulling up. Therefore, when operating the snow removal lever 40, the operator can pull up the lever 40 with a light force, and also requires a light force when gripping and holding the lever 40 together with the steering loop handle 30.
In this manner, the action of the tension spring 60 facilitates the operation of the snow removal lever 40.

After the snow removal work to the designated location is completed, the snow removal machine 10
0, the operator only has to release his hand from the snow removal lever 40. By doing so, the snow removal lever 40 and the travel lever 30
are pulled back by respective clutches (not shown) and moved to the non-operating position shown in FIG. 1, and the snow removal mechanism section A and traveling mechanism section B stop. When the snow removal lever 40 moves from the operating position to the non-operating position, the tension spring 60 moves from the state shown in FIG. 2b to the above-mentioned state as shown in FIG. located in the lower region of the pins 41, 41, thereby causing the tension spring 60
The force acts in the direction of pulling down the snow removal lever 40. As a result, the snow removal lever 40 is reliably held in the non-operating position by the combined action of the force of the clutch (not shown) and the force of the tension spring 60.

[Effect of idea]

As detailed above, in the snow blower according to the present invention, both the steering handle and the snow removal clutch lever are loop-shaped, and when the snow removal clutch lever is operated, Since the driving clutch lever is also operated, by operating an appropriate part of the snow removal clutch lever, the snow removal mechanism and the driving mechanism can be operated together to perform snow removal work.

Therefore, the degree of freedom of the operator's working posture during snow removal work is increased, and the operator can perform snow removal work in a comfortable posture.Moreover, due to the action of the tension spring connected to the steering handle and the snow removal clutch lever, Since the snow removal clutch lever can be grasped together with the steering handle with light force, the snow removal machine can be easily maneuvered.

Further, according to the configuration of the present invention, by releasing the snow removal clutch lever, the traveling clutch lever is also released together with the snow removal clutch lever, and the snow removal mechanism section and the traveling mechanism section are stopped at the same time. Since the clutch lever is restrained in the non-operating position by the tension spring, it is possible to prevent the snow blower from leaving the operator's hands and traveling independently.
