Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Examples
As shown in fig. 1-3, a novel blade device of a small excavator comprises a blade 1 and a scraper 2, wherein a slide block 3 is slidably mounted on the upper end surface of the blade 1; a first groove 301 is formed in the lower end face of the sliding block 3; a motor 4 is fixedly connected to one side of the slide block 3, which is far away from the inner contour of the dozer blade 1; the output end of the motor 4 is fixedly connected with the rotating shaft 5; the rotating shaft 5 is rotatably arranged on the side wall of the first groove 301 through a bearing 6; a gear 8 is sleeved on the rotating shaft 5; the gear 8 is meshed with a rack 7 arranged on the upper end surface of the dozer blade 1; a scraper 2 is fixedly connected to one side of the slide block 3 close to the inner contour of the dozer blade 1; the cutting edge of the scraper 2 fits the inner contour of the blade 1.
Above-mentioned dozer blade device drives pivot 5 through motor 4 and rotates to drive gear 8 and rotate, under the effect of rack 7, gear 8 and slider 3 carry out the back-and-forth movement, thereby drive scraper blade 2 back-and-forth movement, will adhere to the earth in dozer blade 1 and scrape off, realize automatic clearance, effectively improve dozer blade 1's work efficiency.
Specifically, in order to prolong the service life of the scraper 2, the scraper 10 is detachably mounted on the cutting edge of the scraper 2.
Specifically, in order to facilitate maintenance and replacement, the sliding block 3 and the scraper 2 are detachably connected.
