Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a safety device for a small snow blower.

[Conventional technology]

Generally, when a pedestrian passes by a small snow blower, the travel clutch lever is turned off to stop the small snow blower and wait for the pedestrian to pass.

And so that snow removal work can be done immediately after passing, the work clutch lever is not turned off, so the auger continues to rotate.

If a pedestrian accidentally slipped on the snow and came into contact with the auger, this could result in serious injury or even death.

[Problem that the invention attempts to solve]

The present invention solves this drawback by providing a safety plate at the opening of the auger case so that it can be opened and closed freely, and unless the traveling clutch lever is put into the running state, the opening of the auger case is blocked by the safety plate and pedestrians are It is a technical problem to provide a safety device for a small snow blower that prevents snow blowers from coming into contact with the auger.

[Means for solving problems]

Snow removal device a consisting of an auger case 2 having an auger 1, a blower case 4 having snow removal blades connected to the rear of the auger case 2, and a snow removal tube 5 connected to the upper part of the blower case 4. is provided at the front of the self-propelled body b, and a handle 7 and a control section 12 are provided at the rear of the self-propelled body b, and the snow removal device a is operated by the drive engine 8 of the self-propelled body b, while the operator follows. In a small snow blower of the type that is operated by hand, the opening of the auger case 2 is covered with a safety plate 9, and both sides of the upper edge of the safety plate 9 are pivoted to both sides of the ceiling of the auger case 2, and the safety plate 9 is An opening/closing actuating device c for the safety plate 9 is provided in the snow removal device a, and a traveling clutch lever 10 is associated with the opening/closing actuating device c.

[Effect]

When the traveling clutch lever 10 is put into the traveling state, the self-propelled body b travels and at the same time the opening/closing actuator c is automatically activated, the safety plate 9 slides to a fixed position in front, and the opening of the auger case 2 is opened. , snow removal work can begin.

When the travel clutch lever 10 is turned off to stop the self-propelled body b from traveling, the opening/closing actuator c is activated again, and the safety plate 9 slides downward to a fixed position to close the opening of the auger case 2.

When the working clutch lever 13 is turned off, the rotation of the auger 1 is stopped.

〔Example〕

The opening/closing actuator c is shown using hydraulic cylinders 11, and the hydraulic cylinders 11 are provided on the left and right walls of the auger case 2, and the rods 3 are pivotally connected to the connecting plates 6 provided on the left and right upper ends of the safety plate 9. , a case is shown in which the safety plate 9 is slid upward to a fixed position and opened by pulling the rod 3.

The relationship between the opening/closing actuating device c and the traveling clutch lever 10 is as follows.
It is preferable to provide a switch mechanism in which the opening/closing actuating device c is turned on when the traveling clutch lever 10 is put into the traveling state, and turned off when it is turned off.

This safety plate 9 is preferably made of iron plate, plastic plate, grid plate, etc.

[Effect of idea]

Since the present invention is constructed as described above, the auger 1
Even if the auger case 2 is rotating, the safety plate 9 will close the opening of the auger case 2 unless the travel clutch lever 10 is put into the running state, so even if a pedestrian accidentally slips on the snow removal device a, the safety plate will close. Since the rotating auger 1 is protected by the auger 9 and is not in contact with the rotating auger 1, serious injuries and accidents involving human life can be prevented.

When the operator starts snow removal work after confirming safety, he puts the traveling clutch lever 10 into the traveling state, and at the same time as the self-propelled aircraft b starts traveling, the opening/closing actuating device c is automatically activated to close the safety plate. Since the opening of the auger case 2 is opened by supporting the safety plate 9 by sliding it to the upper position, snow removal work can be started immediately after a pedestrian passes without having to open the safety plate 9 by hand each time, resulting in extremely high work efficiency. will improve.

Furthermore, if a pedestrian approaches while clearing snow and feels dangerous, the traveling clutch lever 10 is cut on the spot to stop the traveling of the self-propelled aircraft b, and at the same time the opening/closing actuator c is activated and the safety plate 9 is slid downward. Since the opening of the auger case 2 is closed, danger can be prevented.

Since the hydraulic system of the opening/closing actuating device c can also utilize the hydraulic system provided in the machine itself, there is no problem in manufacturing.

In this way, the present invention provides a safety device for a small snow blower with excellent safety.

Claims (1)

[Scope of utility model registration request] A snow removal device consisting of an auger case with an auger, a blower case with snow removal blades connected to the rear of the auger case, and a snow removal tube connected to the top of the blower case is installed at the front of the self-propelled aircraft. In this type of small snow blower, a handle and a control section are provided at the rear of the self-propelled body, and the snow removal device is operated by the drive engine of the self-propelled body, while the operator follows and operates it. The safety plate is hidden by a safety plate, both sides of the upper edge of this safety plate are pivoted to both sides of the ceiling of the auger case so that the safety plate can be opened and closed freely, and an opening/closing operation device for this safety plate is provided on the snow removal device. This safety device for a small snow blower is characterized in that a traveling clutch lever is associated with an opening/closing actuating device, and an opening of an auger case is opened when the traveling clutch lever is put into a traveling state.
