Description

[Detailed Description of the Invention] The present invention relates to an auger case device for a small snow blower that can perform forward snow removal operations reliably and smoothly, and its configuration will be described in detail with reference to the accompanying drawings showing one embodiment. Then, it is as follows.

An auger case 3 having left and right side plates 2 and an open front is provided at the front of the fuselage 1.
An auger 4 is mounted inside the auger case 3, and as the auger 4 rotates, snow is introduced into the auger case 3 while being scraped off. In a small snow blower that blows snow away, the middle of the front edge of the left and right side plates 2 of the auger case 3 is formed into a bulged edge that protrudes forward from the upper and lower parts, and this bulged edge is provided with an uneven cutting blade for cutting snow. It is formed by forming a cutting blade body 7 having a shape.

The mounting base 8 of the auger case 3 shown in this figure is pivoted to a fulcrum shaft 9 horizontally suspended at the rear of the machine so that it can swing vertically, and a swing cylinder 10 (a hydraulic jack can also be used) is attached to the mounting base 8. The cylinder rod of this swinging cylinder 10 is pivotally connected to the machine body 1, and the swinging cylinder 10 is operated by an operating lever 11 so that the auger case 3 swings up and down about the fulcrum shaft 9. This vertical swinging motion further improves the snow cutting action of the cutting blade 7.

Reference numeral 12 is a crawler belt, 13 is a prime mover, and 14 is a handle. The front edges of the left and right side plates of conventional auger cases are formed into smooth curved edges, so when moving forward to remove snow, the front edges of the left and right side plates collide with the snow, which increases the forward snow removal resistance and reduces snow removal efficiency. However, in the case of hard snow rather than soft snow, there was a problem in that it was impossible to move forward with snow removal.

In order to solve this problem, the present invention forms a cutting blade body 7 with an uneven cutting edge shape for cutting snow on the front edge of the left and right side plates 2 of the auger case 3, so that when the machine body 1 performs snow removal operation, The snow that collides with the front edges of the left and right side plates 2 is cut by the uneven cutting blade 7, even if it is hard snow, which makes the forward movement smoother and extremely efficient. This means that snow removal work can be done.

In particular, since the middle of the front edges of the left and right side plates 2 is formed into a bulging edge that protrudes forward from the upper and lower parts, a smoothing action is created and even hard snow can be reliably broken.For example, in an auger case. If the auger case device is designed to be able to be raised and lowered, the cutting performance will be even better, and the forward movement of snow removal will be performed more reliably and smoothly, thereby providing an auger case device for a small snow blower that has excellent practical effects.

Claims (1)

[Scope of utility model registration request] An auger case with left and right side plates and an open front is installed at the front of the machine, and an auger is mounted on a shaft within this auger case.As the auger rotates, snow is introduced into the auger case while being scraped off. In a small snow blower that uses a blower to blow the introduced snow far away through a snow blower, the middle of the front edge of the left and right side plates of the auger case is formed into a bulge that protrudes forward from the upper and lower parts. This auger case device for a small snow blower is formed by forming a cutting blade body with an uneven cutting edge shape on the swollen edge to cut snow.
