Description

Technical Field

[0001] The utility model belongs to the technical field of granite mining, and particularly relates to a mining hammer for granite mining. Background Art

[0002] In the process of granite mining, it is necessary to use a mining hammer to strike the rock, that is, to strike the rock with the square head end to break it into pieces; use the sharp edge or flat wedge-shaped end to strike along the rock layer surface to perform rock layer stripping, so that users can conveniently sample.

[0003] The existing mining hammers for granite mining can meet the basic requirements for hammering ore and can flexibly adjust the effective length of the holding structure. However, they usually adopt multiple connecting holes arranged at intervals, and adjust the limited length of the holding structure by connecting different connecting holes. Therefore, the adjustable length that can be achieved is not continuous and can only be adjusted in a limited number of lengths, so it cannot fully meet people's usage requirements.

[0004] For example, the utility model with the publication number of CN 220599800 U discloses a mining hammer convenient for mining. Three groups of through holes opposite to each other are arranged on the top side of the sliding rod, and jacks with matching specifications are arranged on the top side of the hammer rod. A limiting bolt and a nut with matching specifications are assembled in the jacks. Through the settings of the sliding rod, the hammer rod and the through holes, the sliding rod can be slid according to needs, so as to increase the length of the device and improve the flexibility and practicability of the mining hammer. However, since different lengths of connection are provided by the through holes arranged at intervals, there are problems of limited types of adjustable length and inability to perform continuous length adjustment.

An anti-slip sleeve 113 is further provided on the outer side wall of the grip 106.

[0026] As Figure 1 , 3 As shown in, a fastening bolt 114 that can abut against the outer side wall of the connecting plug board 104 and thus fix the connection between the connecting slot 105 and the connecting plug board 104 is also screwed on the connecting slot 105.

[0027] As Figure 1 , 2As shown, a first connection slot 301 for clamping and fixing the lower end of the hammer head 102 is provided at the top of the hammer base 101. A first connection bolt 302 for screwing and fixing the lower end of the hammer head 102 is screwed onto the first connection slot 301. A first threaded connection hole adapted to the first connection bolt 302 is provided at the lower end of the hammer head 102. The user can make the lower end of the hammer head 102 be clamped and fixed with the first connection slot 105, and make the first connection bolt 302 pass through the side wall of the first connection slot 105 and be screwed and fixed with the first threaded connection hole, so as to realize the flexible fixation of the hammer head 102 and the hammer base 101.

[0028] As Figure 1 , 2 shown, a second connection slot 303 for clamping and fixing the upper end of the hammer tip 103 is provided at the bottom of the hammer base 101. A second connection bolt 304 for screwing and fixing the upper end of the hammer tip 103 is provided on the second connection slot 303. A second threaded connection hole adapted to the second connection bolt 304 is provided at the upper end of the hammer tip 103.
