Detailed Description

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model.

As shown in fig. 1, 3 and 4, the utility model provides a protective structure for mining machinery, which comprises mounting rods 1 arranged at four corners of a cab roof M, wherein a detachable stone collecting structure is arranged between the four mounting rods 1, the stone collecting structure comprises a net bag 2, the four corners of the net bag 2 are arranged on the four mounting rods 1, and the lowest position of the center of the net bag 2 is positioned right above the cab roof M in a natural state.

As shown in fig. 2, in the utility model, specifically, an adjusting member 3 is arranged on a mounting rod 1, the mounting rod 1 is a threaded rod, the adjusting member 3 is a nut screwed on the mounting rod 1, lantern rings 4 are fixed at four corners of a string bag 2, the lantern rings 4 are sleeved on the mounting rod 1, the lantern rings 4 are positioned above the adjusting member 3, a spring 5 is arranged between the lantern rings 4 and the adjusting member 3 for better protecting the string bag 2, and the spring 5 is sleeved on the mounting rod 1.

The stone on the external hillside falls behind driver's cabin roof M, can be received by string bag 2, collect, and the stone falls behind string bag 2 in addition, can be by impact force, drive string bag 2 and move down, and then drive lantern ring 4 and move down along installation pole 1, extrusion spring 5, cushion impact force, not only protect string bag 2, can also protect pneumatic cylinder 6, the nut rotates from top to bottom, make it reciprocate along installation pole 1, and then adjust the height of lantern ring 4 on installation pole 1 to adjust the tensioning degree of string bag 2, can also adjust the height of string bag 2, in order to be suitable for different operational environment.

As shown in fig. 4, in order to clean the stones in the net bag 2, the cab roof M is further provided with a hydraulic cylinder 6 arranged vertically, the hydraulic cylinder 6 is controlled by an external hydraulic source, a push plate 7 is fixed at the upper end of a piston rod of the hydraulic cylinder 6, the push plate 7 is located right below the center of the net bag 2, and when too many stones are collected in the net bag 2.

When the stones in the net bag 2 need to be cleaned, the hydraulic cylinder 6 is started to drive the push plate 7 to move upwards to push the center of the net bag 2 to move upwards, so that the center of the net bag 2 is higher than the four sides of the net bag, the stones can be ejected out of the net bag 2 and fall on the ground, when the stones need to be cleaned, workers need to be observed around a cab, a nut can be screwed on the installation rod 1, the nut is located above the lantern ring 4, the lantern ring 4 is limited, when the center of the net bag 2 moves upwards, the net bag 2 is separated from the installation rod 1, the nut is unscrewed from the installation rod 1, the disassembly of the lantern ring 4 can be realized, and the disassembly of the net bag 2 is realized.

Finally, the most significant contribution of the present utility model over the prior art is: the net bag 2 can collect the stone that falls in driver's cabin roof M department, prevents that the stone from falling from driver's cabin roof M and smash the staff who stands at one side of driver's cabin, better protection staff, through pneumatic cylinder 6 moreover, can clear up the stone roof in the net bag 2, simple structure, the practicality is high.

Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made therein without departing from the principles and spirit of the utility model, the scope of which is defined in the appended claims and their equivalents.
