Embodiment
The utility model is elaborated with specific embodiment below in conjunction with the accompanying drawings：
Specific embodiment, as depicted in figs. 1 and 2, fully-mechanized digging machine cutterhead protective cover, including shield body, be used for
The detent mechanism of shield body and fully-mechanized digging machine is connected, detent mechanism includes positioning pipe 1, the rear end set being fixedly connected with fully-mechanized digging machine
It is locked mounted in the inside of positioning pipe 1 and with positioning pipe 1 and telescoping tube 2 that front end is fixedly connected with shield body, protective cover
Body is frame-type structure and left plate 4, the right plate 5 and front side board surrounded by top plate 3, left plate 4, right plate 5 and front side board 6
6 upper end is all be hinged with top plate 3, and top plate 3 is fixedly connected with the front end of telescoping tube 2.
When fully-mechanized digging machine does not work, telescoping tube 2 is stretched to forward correct position, made by top plate 3, left plate 4, right plate 5
The frame-type structure surrounded with front side board 6 can cover on cutterhead inside it, and then telescoping tube 2 and positioning pipe 1 are locked
.When fully-mechanized digging machine works, telescoping tube 2 is stretched backward and returns to initial position, top plate 3, left plate 4, right plate 5 and front side
Plate 6, which is all taken, to be placed on fully-mechanized digging machine, does not interfere with the normal use of cutterhead, good environment is created to downhole production, to worker
Underground work provides safety guarantee, eliminates the psychological shade of worker, improves the efficiency of worker.It is possible to prevente effectively from
The generation of fully-mechanized digging machine cutterhead casualty accident, has not only ensured safety in production, avoids loss, and eliminates thing may occur
Therefore the baneful influence brought.
It is fixedly connected as to further improvement of the utility model, telescoping tube 2 with the lower surface of top plate 3, positioning pipe 1 pushes up
The front end in portion opens up fluted 7, and the upper surface of groove 7 is formed as the sliding platform of top plate 3, and the rear and front end of positioning pipe 1 is all opened
Provided with the pin-and-hole being disposed radially, the rear end of telescoping tube 2 is locked by the bearing pin being arranged in pin-and-hole and the rear end of positioning pipe 1 or front end
It is fixed.Opening up for groove 7 causes telescoping tube 2 to have sufficiently large regulation space along the longitudinal direction, can meet that different sizes are comprehensive
The use demand of pick machine.
The length of groove 7 along the longitudinal direction is more than or equal to the length of top plate 3 along the longitudinal direction, is so worked in fully-mechanized digging machine
