BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a snow removal device for a snowplow provided with a vibrating coulter vibrating in the front-rear direction below a center drive type auger transmission case.

[0002]

2. Description of the Related Art At present, most of walking-type self-propelled small snow plows employ a center drive system having an auger transmission case that is rotatably driven while supporting an auger shaft to the left and right.

[0003]

In the above-mentioned center drive type snow removing machine, a power transmission shaft portion for transmitting power from a blower that blows up the snow scraped by the auger to the auger transmission case, that is, a portion below the auger transmission case. Snow (or ice) on the side cannot be directly processed by the auger and may remain as residual snow (residual ice). The remaining snow (residual ice) remains in a hard state when the snow removing operation is next performed, so that the remaining snow may be caught by the scraper of the auger housing and the operation may be interrupted. The present invention has been made to solve the above problems.

[0004]

In order to achieve the above object, the present invention provides: In a snow blower equipped with a center drive type auger transmission case 2 which is rotatably driven while supporting the auger shaft 7 in the left and right directions, the lower part of the auger transmission case 2 vibrates in the front-rear direction, and the lower part of the auger transmission case 2 B. A vibratory coulter 16 for removing snow and ice on the side is provided. The power to the vibrating coulter 16 is supplied to the auger shaft 7
And is taken out from the auger flange 12 having the axis O1 which is coaxial with the axis O of the auger shaft 7 and is shifted by S from the axis O of the auger shaft 7.

[0005]

With the above arrangement, the apparatus for removing snow from a snowplow according to the present invention performs the following operations. . The snow and ice on the lower side of the auger transmission case 2 are separated by the vibrating coulter 16 and are scraped by the auger 8, leaving no remaining snow (remaining ice). . The power of the vibrating coulter 16 is
Since it is taken out from the power source, the configuration is simple and power transmission is reasonable.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be specifically described below with reference to the accompanying drawings. In the drawing, reference numeral 1 denotes an auger housing of a walking-type self-propelled type small snow plow, and the auger housing 1 is provided with an auger gear case 2 at the center 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 supported in the blower case 3. A blower shaft 5 extending forward from a rotation axis of the fan 4 is provided. It is connected to and connected to the auger gear case 2 to transmit power. The auger gear case 2 is provided with an upper auger driving chain case 6 extending upward, and an upper auger (not shown) is supported at the upper end of the chain case 6.

An auger shaft 7 (one of which is omitted in the drawing) extending to the left and right sides is supported by the auger gear case 2.
An auger 8 as a lower (main) auger is attached to the auger shaft 7.
Is installed. At the lower end of the auger gear case 2, the base end of a scraper stay 9 is fixed and extends downward, and a scraper 10 is attached to the lower end of the stay 9.

An auger shaft 7 extending from the auger gear case 2 to both the left and right sides is connected by a flange portion 11. An auger flange 12 is formed on the flange portion 11 coaxially with the auger shaft 7 and has an axis O1 whose axis is shifted by S from the axis O of the auger shaft 7 and is eccentric. A bearing 13 is fitted into the bearing. One end of a cam link 14 is fixed to the outer periphery of the bearing 13 downward. On the other hand, at the front of the stay 9 for the scraper, the front of the stay 15 for the coulter is pivotally supported by a support shaft 17 so as to be able to rotate back and forth.
Is pivotally mounted at the other end. A coulter 16 is attached to a lower end of the stay 15.

In the snow removing device for a snow remover having such a configuration, when the snow removal operation is performed, the auger shaft 7 is driven by the power from the auger gear case 2 to rotate the auger 8 with the power of the auger gear case 2 as the machine body advances. By rotating the upper auger at the upper end of the chain case 6, snow accumulated on the road or the like is scraped into the auger housing 1 by the auger 8 and the upper auger while being scooped by the scraper 10, and the auger housing 1 It is sent to the left and right center. Then, the snow collected at the center is sucked by the fan 4, and is discharged from the blower case 3 to the side of the road with a vigorous force through a discharge tube (not shown).

When the auger shaft 7 is driven and rotated during the snow removing operation, the auger flange 12 is eccentrically rotated to move the bearing 13 up and down, and the coulter stay 15 is supported via the cam link 14 and the pin 18 by the support shaft 17. Is reciprocated back and forth at a predetermined amplitude around the center, and the coulter 16 is vibrated back and forth. Due to the vibration of the coulter 16, snow (or icing) on the lower side of the auger gear case 2 is peeled off,
It is scraped into the auger housing 1 by the auger 8 or the scraper 10, is sucked by the fan 4 together with other snow, and is discharged from the blower case 3 to the side of the road through the discharge tube.

Therefore, in the snow blower equipped with the snow residual processing device of the present invention, the snow (or ice) on the lower side of the auger gear case 2 cannot be processed by the auger and remains as residual snow (residual ice). The next time snow removal is performed, the scraper 1 does not remain in a hard state.
A situation in which the operation is interrupted by being stuck at 0 does not occur, and efficient operations can be performed continuously. The present invention can be applied not only to the walking-type self-propelled type snow plow but also to other center-drive snow plows.

[0012]

According to the present invention, as described above, the following effects can be obtained according to the snow removal processing device of the snow blower of the present invention. . Vibrates in the front-back direction at the lower part of the auger transmission case 2,
Since the vibratory coulter 16 for removing snow and ice on the lower side of the auger transmission case 2 is provided, the auger transmission case 2
The snow and ice on the lower side are separated by the longitudinal vibration of the vibratory coulter 16 and are scraped by the auger 8, so that there is no remaining snow (remaining ice), and efficient snow removing work can be performed. . Since the power to the vibrating coulter 16 is taken out from the auger flange 12 having the axis O1 which is coaxial with the auger shaft 7 and has an axis O1 offset from the axis O of the auger shaft 7 and offset from the axis O, Although the configuration is simple, the power transmission can be performed without difficulty and without fail.
