DETAILED DESCRIPTION

[0027] The application provides a scraper for a flotation machine, which can realize quick switching.

[0028] To achieve the above technical purpose, the application adopts the technical scheme of a scraper for a flotation machine, which comprises

[0029] (1) a scraper main shaft 4, one end of which is driven to rotate by a driving device 1, and the other end of which is installed on a shaft sleeve transmission seat 7. That is, one end of the scraper main shaft 4 is driven to rotate by the driving device 1, and the other end can rotate relative to the shaft sleeve transmission seat 7, and the shaft sleeve transmission seat 7 only provides support force for the scraper main shaft 4. The shaft sleeve transmission seat 7 has a structure for providing support for the scraper main shaft 4 so that it can rotate, and any structure that can achieve this technical purpose can be used, and in the application, the surface of the shaft sleeve transmission seat 7 that provides support force for the scraper main shaft 4 is arc-shaped.

[0030] (2) a scraper fixing member (i.e., a scraper fixing device 10), which is fixed to the scraper main shaft 4 and perpendicular to the scraper main shaft 4. In order to ensure that the scraper 8 is uniformly stressed, the scraper fixing member has multiple scraper fixing members, and the multiple scraper fixing members are fixed to the scraper main shaft 4 at equal intervals.

[0031] (3) two scrapers 8, which are fixed to the two ends of the scraper fixing member and parallel to the scraper main shaft 4. In actual application, the scrapers 8 are detachably installed at the two ends of the scraper fixing member to facilitate replacement and adjustment of the relative position of the scrapers and the scraper fixing member.

[0032] (4) two scraper support members (i.e., scraper support devices 9), which are respectively located at the two ends of the scraper fixing member; and the scrapers 8 are fixed to the scraper fixing member through the scraper support members. That is, the scraper support members are connected to multiple scraper fixing members at the same time, and the scrapers only need to be installed on the scraper support members, which can reduce the operation complexity of replacing the scrapers and adjust the relative distance between the scrapers and the scraper main shaft 4. At the same time, because the material of the scrapers 8 is made of belt leather, the scraper support devices 9 are added to support the scrapers 8 considering the toughness of the scrapers.

[0033] Specifically, in order to conveniently adjust the relative position of the scraper 8 (the relative distance between the scraper 8 and the scraper spindle 4), the end of the scraper support is provided with a scraper adjusting hole 11, which is in the shape of a long strip; the length direction of the scraper adjusting hole 11 is perpendicular to the axis direction of the scraper spindle 4; the scraper 8 is installed on the scraper support through the scraper adjusting hole 11; and the position of the scraper 8 relative to the scraper support is adjustable. In fact, it is also considered that there will be wear and sinking problems in the relative operation of the scraper shaft sleeve 6 and the shaft sleeve transmission seat 7 during operation, so the scraper adjusting hole 11 is added to ensure that the scraper 8 can be adjusted in extension and retraction, so as to make micro-adjustment during production. In addition, the scraper adjusting hole 11 can be adjusted during installation. Therefore, a long hole which is adapted to the scraper 8 is provided on the surface of the scraper support device 9, so as to conveniently adjust the position of the scraper 8.

[0034] (5) The scraper shaft sleeve 6 is internally provided with a groove one; the two ends of the scraper spindle 4 are respectively provided with scraper shaft heads 5, the two ends of the scraper shaft head 5 are respectively provided with grooves two at positions corresponding to the groove one; the output end of the driving device 1 is provided with the scraper shaft sleeve 6, the shaft sleeve transmission seat 7 is provided with the scraper shaft sleeve 6, the scraper spindle 4 is installed in the inside of the scraper shaft sleeve 6, and a key pin is simultaneously keyed into the groove one and the groove two.
