utility model content:
The purpose of this utility model is to provide a kind of buffering scraper, can rapid-assembling, also can in mill rapid disassembling, easy maintenance, achieves automatic turning and the reset function of material scraping plate, initiatively can dodge foreign matter, and foreign matter is discharged grinding machine, thus the continuity of support equipment safety and production.
The technical solution of the utility model is as follows:
Buffering scraper, comprise the support of milling equipment, it is characterized in that: below described support, be welded with multiple limit opening cover spaced apart, be set on axle in limit opening cover, axle be also set with the spaced torque spring of many groups, wherein often organize the both sides that torque spring is distributed in corresponding limit opening cover, also comprise material scraping plate, scraper sleeve-board is also set on axle, and material scraping plate upper end is provided with opening, is wherein distributed with one group of torque spring and a limit opening cover between each opening; The lower end of described each torque spring props up the back side of material scraping plate.
Described buffering scraper, it is characterized in that: described limit opening cover quantity is for being generally two, limit opening cover comprises the installing plate that upper end is fixed on pedestal lower end face, installing plate lower surface is provided with integrated crotch, the inwall radian of crotch matches with axle outer wall, and crotch opening is slightly larger than axle external diameter.
Described buffering scraper, is characterized in that: described torque spring is 90 ° of torque springs, and 90 ° of torque spring quantity are generally two groups, often organizes the both sides that relative torque spring is distributed in corresponding limit opening cover.
Described buffering scraper, is characterized in that: the two ends outer wall of described axle screws and is provided with nut, nut withstands the outer wall of described material scraping plate, and the two ends of axle radially offer through hole, is provided with the limit opening pin matched with nut in through hole.
The utility model has the advantages that:
The utility model reasonable in design, utilize the moment of torsion function of torque spring, realize automatic turning and the reset function of material scraping plate, initiatively can dodge foreign matter, and foreign matter is discharged grinding machine, thus support equipment safety and the continuity of producing, in addition can rapid-assembling, also can in mill in rapid disassembling, easy maintenance.
