Dirt cleaning grab bucket capable of crushing consolidated dirt on trash rack
The invention discloses dirt cleaning grab bucket capable of crushing consolidated dirt on a trash rack. The trash cleaning grab bucket mainly comprises a grab bucket frame 1, a rotary rake claw driving system 2, a guide device 3, a rotary rake claw 4, grab bucket shovel teeth 5, a pickaxe rod 6 and a pickaxe rod driving mechanism 7. When the consolidated dirt cleaning grab bucket is used for carrying out dirt cleaning operation and the consolidated dirt on the trash rack is propped against the lower part of the grab bucket, the pickaxe rod driving mechanism 7 arranged on a rotary rake frame can drive the pickaxe rod 6 to carry out reciprocating impact vibration motion, so that the consolidated dirt propped against the lower part of the grab bucket is crushed and loosened, and the dirt cleaning grab bucket can grab the consolidated dirt. According to the dirt cleaning grab bucket, the reciprocating pickaxe rod is used for crushing and loosening the consolidated dirt consolidated in front of and at the bottom of the trash rack and attached to the surface of the trash rack, so that the consolidated dirt can be grabbed without increasing the insertion force of bucket teeth by increasing the dead weight of the grab bucket, and the dirt cleaning grab bucket is simple in structure, convenient to operate, capable of greatly saving the project investment and high in working efficiency, according to the scheme, the good trash cleaning effect can be achieved with small investment, meanwhile reliable guarantee is provided for normal operation of dirt cleaning work of the trash rack of a power station. Therefore, the trash cleaning grab bucket is widely practical.
本发明公开了设计一种可以破碎拦污栅固结污物的清污抓斗，该清污抓斗主要由抓斗架1、转动耙爪驱动系统2、导向装置3、转动耙爪4和抓斗铲齿5、镐钎6、镐钎驱动机构7组成。该清污抓斗在进行清污作业时，当拦污栅栅固结污物顶在抓斗下部时，可以通过装在转耙架上的镐钎驱动机构7驱动镐钎6进行往复的冲击振动运动，对顶在抓斗下部的固结污物进行破碎和松散，使清污抓斗的能够抓取这些固结污物。由于本发明是利用往复运动的镐钎来破碎和松散固结在拦污栅栅前、栅底以及附着在栅面的固结污物，故不需要通过增加抓斗的自重增加斗齿插入力来抓取固结污物，本发明结构简单，操作方便，还能大大节约工程投资，是一种投入较小即可获得良好清污效果的方案，同时为电站拦污栅清污工作的正常运行提供可靠的保证。因此，该发明具有广泛的实用的。
