锚喷支护机具又有新的发展——泰山转子V型混凝土喷射机在山东泰安煤矿机械厂研制成功。该机是在保持了转子型混凝土喷射机其优点的基础上研制的,它克服了其它转子型喷射机的不足。该机的主要特点是:1)增加了一个清扫室。在清扫室内设了两道清扫刷子(清扫器),清扫器的清扫板与旋转板的接触间隙由压弹簧来调节。由于采用了这种清扫装置,间隙能自动补偿,所以旋转板带过来的砂、石、水泥可全部清扫干净,不被带进扇形板的磨擦面内,这样就避免了砂石把扇形板划伤,磨坏,跑风漏尘,粉尘过高等问题,同时也延长了扇形板的使用寿命。2)扇形板的压紧由原来的螺丝压紧改成用斜形压铁,压铁的外端用螺丝作顶
Anchoring and spraying equipment has a new development - Taishan rotor V-type concrete jet in Shandong Tai’an Coal Mine Machinery Factory successfully developed. The machine is based on the advantages of the rotor-type concrete jet developed on the basis of it overcomes the shortcomings of other rotor-type jet. The main features of the aircraft are: 1) an increase of a clean room. Two cleaning brushes (cleaners) are provided in the cleaning chamber, and the contact clearance between the cleaning plate and the rotating plate of the cleaner is adjusted by the pressure spring. Because of this cleaning device, the gap can be automatically compensated, so the rotating plate over the sand, stone, cement can be completely cleaned, not to be brought into the friction surface of the sector plate, thus avoiding the sand to the sector plank Injury, wear and tear, runny dust leakage, dust and other issues, but also extend the life of the sector board. 2) The compression of the fan board is changed from the original screw pressing to the diagonal pressing iron, and the outer end of the pressing iron is used for screwing to the top
