Description

[Detailed description of the invention] [Industrial field of application] This invention relates to a snow clog removal device for a small snow blower.

[Conventional technology]

Recently, small snow blowers have become popular in ordinary households, and accidents have been occurring frequently as a result.

The most common accidents occur when removing snow that has become clogged inside the blower case or the tip of the snow shovel.

In other words, when the snow is clogged, the drive belt slips and the snow removal blades do not rotate, so if you put your hand in to remove the snow under the illusion that the snow removal blades are stopped, the load on the snow removal blades will be removed. It rotates again, causing damage to your hand.

[Problem that the invention attempts to solve]

The present invention solves these drawbacks and is a compact snow blower that can easily and safely remove clogged snow by pushing it out from the outside into the auger case using a snow extrusion plate. It is a technical problem to provide a blockage removal device.

[Means for solving problems]

An auger case 2 having an auger 1, a blower case 4 having snow removal blades 3 connected to the rear of this auger case 2, a snow removal tube 5 connected to the upper part of this blower case 4, and this snow removal A snow removal device a consisting of a snow throwing cover 6 provided on a snow tube 5 is provided at the front of the self-propelled body b, and a handle 7 and a control unit 8 are provided at the rear of the self-propelled body b to drive the self-propelled body b. In a small snow blower of the type in which a snow removal device a is operated by an engine 9 while being operated by an operator, the top portion 4a of the blower case 4 is positioned near the tip of the snow removal tube 5, and the auger case 2 A snow extrusion space 10 is formed between the rear part and the rear of the tip of the snow removal tube 5, and an extrusion rod 11 is inserted and protruded into the rear of the tip of the snow removal tube 5 so that it can be freely pulled out into the snow removal tube 5. A snow extrusion plate 12 is provided at the tip of the extrusion rod 11.

[Effect]

If the tip of the snow removal tube 5 is clogged with snow, remove the ejection rod 1.
When 1 is pressed, the snow that is clogged with the snow extrusion plate 12 is passed through the snow extrusion space 10 and the auger case 2
Since the snow is pushed inward, the clogged snow condition is removed.

〔Example〕

The drawing shows a structure in which the extrusion rod 11 is pulled by a wire 14 or the like, and when this pulling state is released, the snow extrusion plate 12 is pushed out by a spring 13, but a structure in which it is pushed out by a cylinder may also be used.
The structure may be such that the material is pushed out using a lever, or it may be pushed out directly by hand, and various other structures are possible.

In the figure, 15 is a mounting bracket.

[Effect of idea]

Since the present invention is configured as described above, when the tip (exit) of the snow shovel 5 is clogged with snow, the pushing rod 11 is pushed in from the outside and the snow pushing plate 12 pushes out the clogged snow, thereby creating a snow pushing space. Since the snow is pushed out into the auger case 2 through the section 10, the snow clogged inside the tip of the snow removal tube 5 can be easily removed.

Since the pushing rod 11 is operated in this way to push out and remove the snow stuck inside the tip of the snow shovel 5, this method is compared to the conventional method of putting one's hand inside the snow shovel 5 to scrape out the snow. It is extremely safe.

In this case, if the drive engine 9 is driven and the clogged snow is removed, the drive belt will immediately transmit the driving force to the snow removal device a, so snow removal work can be started immediately, improving work efficiency. This has practical effects.

Claims (1)

[Scope of utility model registration request] An auger case having an auger, a blower case having snow removal blades connected to the rear of the auger case, a snow removal tube connected to the top of the blower case, and a snow throwing tube provided to the snow removal tube. A snow removal device consisting of a cover is installed at the front of the self-propelled aircraft, and a handle and a control section are provided at the rear of the self-propelled aircraft.The snow removal device is operated by the drive engine of the self-propelled aircraft, while an operator follows. In a small snow blower of the type that can be operated, the top of the blower case is positioned near the tip of the snow removal tube to form a snow pushing space between the back of the auger case and the rear of the tip of the snow removal tube. This safety device for a small snow blower is characterized in that an extrusion rod is inserted and protruded from the rear of the tip of the snow removal tube so as to be freely drawn out into the snow removal tube, and a snow extrusion plate is provided at the tip of the extrusion rod.
