Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below. The embodiments of the present invention, all other embodiments obtained by a person skilled in the art without creative work, all belong to the protection scope of the present invention.

Referring to fig. 1 to 2, the present invention provides a technical solution: the utility model provides a mine blasting is with breakage-proof stone landing device, includes bottom plate 1 and an upper fixed plate 2, and movable mounting has a telescopic link 6 on the upper fixed plate 2, and the car has connect inserted bar frame 7 in the telescopic link 6, and the one end movable mounting of inserted bar frame 7 has installation axle 3, and the other end movable mounting of installation axle 3 is on bottom plate 1, and fixed mounting has rolling axle 4 on installation axle 3, and the rolling of rolling axle 4 has protection network 5.

The both ends of rolling axle 4 are equipped with protection network compact structure, and protection network compact structure comprises clamp plate 9, screw thread post 10 and screw cap 11, and screw thread post 10 is installed perpendicularly at the tip of rolling axle 4, has cup jointed clamp plate 9 on the screw thread post 10, and screw thread are installed to the one end of screw thread post 10 and screw cap 11, can make clamp plate 9 compress tightly protection network 5 through screw cap 11.

One end of the sleeve rod 6 is provided with a threaded hole, a threaded bolt 8 is installed in the threaded hole in a threaded mode, the inserted rod frame 7 can be fixed through the threaded bolt 8, and the inserted rod frame 7 is convenient to adjust in length.

Card hole 51 has been seted up at the both ends of protection network 5, and card hole 51 is provided with a plurality of groups, is the even equidistance array of line at the both ends of protection network 5, and fixed mounting has card hole iron ring on the card hole 51, can increase card hole 51's integrality, avoids card hole 51 to be torn badly at the in-process that uses.
