The utility model belongs to a shovel knife-driven blanking pipe dredger, which comprises a blanking pipe, which is divided into a straight pipe part and an oblique part. An organism is installed on the outer side of the oblique part at the intersection of the straight pipe part and the oblique part of the blanking pipe. A deceleration lifting mechanism and a motor connected with the deceleration lifting mechanism are arranged on the outer side of one end of the body, and a retreat cavity is arranged on the outer side of the body to decelerate the deceleration lifting The lifting mechanism is equipped with a drive screw, the external threads of the drive screw are arranged, the push-pull rod is set on the drive screw, the internal threads of the push-pull rod are matched with the external threads on the inner diameter of the push-pull rod, and one end of the push-pull rod is equipped with a spade. The push-pull rod passes through the inner part of the body and the back cavity and extends into the inner part of the blanking tube along the inclined face of the blanking tube. One end has a sealed chamber, which has the advantages of ingenious and reasonable structure design, convenient operation, automatic control, cleaning process does not affect the normal use of the machine, and good cleaning effect.

技术介绍
落料管堵料、断料,下料不畅一直是困扰发电等相关企业的头痛而又普遍问题,轻则造成人力物力的极大浪费,重则造成发电不足,甚至停炉灭火。下图是比较典型的一个电厂落料管。堵料情况表现在,从磨煤机进口的斜面处开始粘接,沿着落料管的直筒段往上积累,越积越高,占据了落料管的内腔,最终将落料管的内腔堵实,引起发电严重不足,并停炉灭火。电厂考虑了多种辅助下料措施,均没有理想的方法。目前只有采用停止送煤,人工敲打,铁棍内捅的方式,解决一时之急。造成落料管堵塞的因素,一是物料的粘性,二是物料运动对管壁的冲刷、挤压。物料输送进入落料管,在物料的运动惯性和重力的作用下,物料呈抛体运动向前下方运动,打在落料管的管壁上。多数物料会反弹流下去,少数物料由于物料的粘性会粘接在管壁上,并且会越积越多,最终形成堵塞。反弹的物料如果再次打到管壁上,一部分物料同样因为粘性而再次粘接,最终形成了落料管的整个堵塞。特别是当物料水分大、粘度大时,粘结、结拱现象更易发生。目前煤价上涨,掺烧劣质煤,煤泥,以 ...
