SUMMARY

[0003] The utility model aims at overcoming the insufficient of prior art, provide a kind of excavator cannon head protection structure.

[0004] To achieve the above object, the utility model is through the following technical scheme to realize:

[0005] A kind of excavator cannon head protection structure, including cannon head main body, cannon head main body is elastically installed with protective cover by telescopic spring, the protective cover includes two fixed plates, several vertical connecting rods and several ring connecting rods, the fixed plate is circular structure, and the movable hole for the lower part of cannon head main body to pass through is reserved on fixed plate, several vertical connecting rods are evenly distributed between two fixed plates, several ring connecting rods connect each vertical connecting rod in the form of multilayer arrangement, form cylindrical structure, at least one layer of steel wire mesh is equipped in the inside of cylindrical structure.

[0006] Further, in two fixed plates, several connecting blocks are equipped on upper fixed plate, one end of telescopic spring is connected with cannon head main body by fixed bolt, and the other end is connected with connecting block.

[0007] Further, the number of connecting block is four.

[0008] Further, two layers of steel wire mesh are equipped in the inside of cylindrical structure.

[0009] Further, steel wire mesh is fixedly connected with cylindrical structure by welding mode. Advantageous effects

[0010] The utility model discloses a protective cover is installed on the main part of the drill head through the spring elasticity, and the telescopic spring is in the slack state under the lifting state of the excavator hook arm, and the protective cover can wrap the drill rod, when the broken concrete and asphalt structure pavement construction, the operating personnel can position the broken position through the protective cover, and is closely combined with the pavement layer, and the debris produced in the broken process is dropped after being impacted in the protective cover, prevents the damage to the surrounding personnel and vehicle in the construction operation process, and also protects the drill rod, saves the artificial cleaning input, and can effectively reduce the dust flying, and the operation energy -conserving environmental protection requirement is met, and has stronger practical value. BRIEF DESCRIPTION OF DRAWINGS

[0011] Figure 1 The structure schematic diagram of the preferable embodiment of the utility model does not contain steel wire net;

[0012] Figure 2 The structure schematic diagram of the preferable embodiment of the utility model does not contain steel wire net;

[0013] In the drawing: the drill head main part 1, telescopic spring 2, connecting block 3, fixed plate 4, vertical connecting rod 5, annular connecting rod 6, drill rod 7, fixed bolt 8, steel wire net 9. DETAILED DESCRIPTION

[0014] The technical scheme in the embodiments of the utility model will be described clearly and completely below in combination with the drawings in the embodiments of the utility model, and obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor belong to the range of protection of the utility model.

[0015] Embodiment: as shown in Figure 1 And Figure 2 Shown, including drill head main part 1, the drill head main part 1 is elastically installed with protective cover through telescopic spring 2, the protective cover includes two fixed plates 4, a plurality of vertical connecting rods 5 and a plurality of annular connecting rods 6, the fixed plate 4 is circular structure, and the fixed plate 4 is reserved with the movable hole (not shown in the drawing) for the lower part of drill head main part 1 to pass through, a plurality of vertical connecting rods 5 are evenly distributed between the two fixed plates 4, a plurality of annular connecting rods 6 are connected to each vertical connecting rod 5 in the form of multilayer arrangement, form the cylindrical structure, and at least one layer of steel wire net 9 is arranged on the inner side of the cylindrical structure.

[0016] More specifically, in the two fixed plates 4, a plurality of connecting blocks 3 are arranged on the upper fixed plate, one end of the telescopic spring 2 is connected with the drill head main part 1 through the fixed bolt 8, and the other end is connected with the connecting block 3, further, the number of connecting blocks 3 is four, that is, the upper fixed plate is connected with the drill head main part 1 through four telescopic springs 2 and four fixed bolts 8,
