Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a snow removal device for a snow remover, which includes a center drive type auger transmission case, and a vibration type coulter that oscillates in the front-rear direction at the bottom of the case.

[0002]

[Prior art]

 At present, most of the walking type self-propelled type small snow removers adopt the center drive system with an auger transmission case that rotates the auger shaft by supporting it horizontally.

[0003]

[Problems to be solved by the device]

 In the above center drive type small snow blower, the transmission shaft part that transmits power from the blower that blows up the snow scraped by the auger to the auger transmission case, that is, the snow (or ice) on the lower part of the auger transmission case. However, it may not be directly processed by the auger, and may remain as residual snow (remaining ice). The remaining snow (remaining ice) may be interrupted by the scraper of the auger housing because it remains in a hard state when the next snow removal work is performed. The present invention has been made to solve the above problems.

[0004]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides (1) a snow blower equipped with a center drive type auger transmission case that pivotally drives the auger shaft to the left and right, and A vibrating coulter that vibrates in the front-rear direction is provided, and (2) the power of the vibrating coulter is taken out from the auger flange.

[0005]

[Action]

 With the above structure, the snow removal device for a snow remover of the present invention performs the following actions. The snow and ice on the lower side of the auger transmission case are separated by a vibrating coulter and scratched by the auger, leaving no residual snow (residual ice). Since the power of the vibration type coulter is taken out from the auger flange, the structure is simple and there is no difficulty in power transmission.

【Example】

 Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings. In the figure, reference numeral 1 is an auger housing of a walking type self-propelled type small snow remover. The auger housing 1 is provided with an auger gear case 2 in the center portion in the left-right width direction. A blower case 3 is fixed to a rear portion of the auger housing 1 behind the auger gear case 2, and a fan 4 is pivotally supported in the blower case 3, and a blower shaft 5 extending forward from a rotation axis of the fan 4 is provided. Is connected to and linked to the auger gear case 2 to transmit power. Further, the auger gear case 2 is provided with an upper auger driving chain case 6 extending upward, and an upper auger (not shown) is pivotally supported at an upper end portion of the chain case 6.

The auger gear case 2 has an auger shaft 7 (one of which is omitted in the drawing) that extends to the left and right sides of the auger gear case 2, and an auger 8 that is a lower (main) auger is attached to the auger shaft 7. A base end of a scraper stay 9 is fixed to the lower end of the auger gear case 2 and extends downward. A scraper 10 is attached to the lower end of the stay 9.

The auger shaft 7 extending from the auger gear case 2 to the left and right sides is connected by a flange portion 11. On the flange portion 11, an auger flange 12 is formed coaxially with the auger shaft 7 and having an axial center O1 deviated from the axial center O of the auger shaft 7 by S, and the auger flange 12 of the auger flange 12 is formed. A bearing 13 is fitted around the outer circumference. One end of the cam link 14 is fixed to the outer peripheral portion of the bearing 13 downward. On the other hand, the front portion of the scraper stay 9 is pivotally supported at the front portion of the scraper stay 15 by a support shaft 17 so as to be able to rotate back and forth. The other end is pivotally attached. A coulter 16 is attached to the lower end of the station 15.

In the snow removal device for a snow removal machine having such a structure, when performing snow removal work, the auger shaft 7 is driven by the power from the auger gear case 2 to rotate the auger 8 as the machine body moves forward, and By rotating the upper auger at the upper end of the chain case 6, the snow accumulated on the road etc. is scraped by the scraper 10 and scraped into the auger housing 1 by the auger 8 and the upper auger. Sent to the center. Then, the snow collected in the center is sucked by the fan 4, and is vigorously discharged from the blower case 3 to the side of the road through a discharge tube (not shown).

When the auger shaft 7 is driven and rotated during such snow removal work, the auger flange 12 eccentrically rotates to move the bearing 13 up and down, and the coulter stay 15 supports the support shaft 17 via the cam link 14 and the pin 18. The coulter 16 is oscillated back and forth with a predetermined amplitude by reciprocating around. Due to the vibration of the coulter 16, the snow (or freezing) on the lower side of the auger gear case 2 is peeled off and is scraped into the auger housing 1 by the auger 8 or scraper 10, and is blown by the fan 4 together with other snow. Is sucked in and is discharged from the blower case 3 to the side of the road through the discharge cylinder.

Therefore, in the snow remover equipped with the snow removal processing device of the present invention, the snow (or freezing) of the lower part of the auger gear case 2 may not be processed by the auger and may remain as the remaining snow (remaining ice). No, the next time the snow removal work is performed, it does not remain in a hard state, so there is no chance that this will get caught in the scraper 10 and the work will not be interrupted, and efficient work can be performed continuously. . The present invention can be applied not only to the walking type self-propelled type small snow remover but also to other center drive type snow removers.

[0012]

[Effect of device]

 As described above, the snow removal device for a snow blower according to the present invention has the following effects. A vibrating coulter that vibrates in the front-rear direction is placed under the auger transmission case, so snow and ice on the lower side of the auger transmission case are separated by the longitudinal vibration of the vibrating coulter and scraped by the auger. Rarely, there is no residual snow (residual ice), and efficient snow removal work can be performed. Since the power of the vibration type coulter is taken out from the auger flange, the structure is simple and reliable power transmission can be performed.
