Abstract
The utility model discloses a cleaner for float coal in a gap between fully mechanized coal mining face frames. The cleaner comprises a handle and an arc-shaped steel plate welded at the front end of the handle; the width of the arc surface of the arc-shaped steel plate is smaller than that of the gap between fully mechanized hydraulic supports; the arc surface of the arc-shaped steel plate faces the handle; the angle between the handle and the arc surface of the arc-shaped steel plate is 75-90 degrees. When the cleaner is used, a worker holds the handle of the cleaner and stretches the cleaner into the gap to scrap the float coal back and forth, so that the cleaning of float coal in the gap between the face frames is realized. Through the adoption of the device, scattered float coal in the gap between the face frames can be recovered effectively, and the recovery rate of coal on the faces is improved.
Description
Technical field
The utility model relates to colliery down-hole combined mining working cleaning device.
Background technology
At present, in the down-hole combined mining working manufacturing process of colliery, often there is float coal to scatter in the space between comprehensive mining hydraulic bracket, narrow space, between frame, float coal is difficult to reclaim.The conventional float coal cleaning tool of conventional face is such as whisk broom, spade etc. are difficult to put to good use between support, and the float coal rate of recovery is too low; Workman clears up float coal time shift frame work careless manipulation and easily causes casualty accident between frame; Float coal cleaning is not deposited in goaf only spontaneous combustion danger.
Summary of the invention
The purpose of this utility model is in order to clear up the float coal between the down-hole combined mining working frame of colliery, and float coal sweeper between a kind of frame is provided,
A kind of combining adopted float coal sweeper between hydraulic pressure frame, it is characterized in that, it is made up of handgrip and the curved plate that is welded on handgrip front end, the cambered surface width of curved plate is less than the gap length between comprehensive mining hydraulic bracket, the cambered surface of curved plate is towards handgrip, and the angle of handgrip and curved plate cambered surface is 75-90 degree.
When use, personnel hold sweeper handgrip and stretch between frame, by scraping clearly back and forth float coal, thereby realize the float coal cleaning between work plane frame.The float coal that adopts this device to be effectively scattered between recovery operation face frame, improves work plane coal recovery rate.
Brief description of the drawings
Fig. 1 is the front view of the utility model embodiment.
In figure: 1-handgrip, 2-steel plate.
Detailed description of the invention
Further illustrate the technical solution of the utility model below by accompanying drawing.
As shown in Figure 1, when the utility model is implemented, first waste steel bar is made handgrip 1, be bent into arc shape as shown in the figure with waste and old steel plate 2, then handgrip 1 is integrally welded with the steel plate 2 that is bent into arc shape, the cambered surface width of steel plate 2 is less than the gap length between comprehensive mining hydraulic bracket, and the cambered surface of steel plate 2 is towards handgrip 1, and the angle of handgrip 1 and steel plate 2 cambered surfaces is 75-90 degree.
