[0002] The actual requirements of drilling or crushing determine the development characteristics of the current drill bits such as performance and efficiency. In reality, when drilling holes or crushing materials, such as partial road crushing or house demolition in urban areas due to engineering factors When the wall is broken and when the viaduct is built, there are some defects. For example, the road is broken in the urban area, and the noise is loud and harsh when the wall is broken; Gravity realizes percussion drilling, so its efficiency is not high, and it is difficult to break it into, and the drill bit is easily worn or damaged, so it is urgent to develop a drill bit structure or device suitable for actual needs

Embodiment Construction
[0026] Example: such as Figure 1-4 As shown, the impact drill rod structure for shock and noise reduction includes a drill rod 1 whose central axis is a hollow structure;
[0027] The drill bit 2 is arranged on one axial end face of the drill rod 1;
[0028] The spring 5 is placed in a drill pipe with a hollow structure in the axial direction;
[0029] The fixed block 6 is arranged on the bottom of one end of the drill bit in the drill rod, and is used to fix one end of the spring 5;
[0030] The upper double-helical grooves 3 are respectively provided on the opposite edge of the other end face of the drill pipe 1 in the axial direction;
[0031] The cross support shaft 4 is placed horizontally on the upper double-helical slot 3, and its two ends exceed the upper double-helical slot 3, which is used to fix the other end of the spring 5 described below, and the excess part is used to support the drill rod described below Top set 7;

The invention relates to a shock absorption and noise reduction impact drill stem structure. The impact drill stem structure comprises a drill stem, a drill bit, a spring, a fixed block, double-helix clamping grooves, a lateral brace shaft and a drill stem top sleeve, wherein a center shaft of the drill stem is of a hollow structure, the drill bit is arranged on one end face in the axial direction of the drill stem, the spring is arranged in the drill stem with the hollow structure in the axial direction, the fixed block is arranged at the bottom of one end, with the drill bit, in the drill stem, the double-helix clamping grooves are formed in the opposite edges of the other end face in the axial direction of the drill stem respectively, the lateral brace shaft is transversely placed on the double-helix clamping grooves, the two ends of the lateral brace shaft exceed the outer edges of the double-helix clamping grooves, and the drill stem top sleeve is arranged at the top of the drill stem in a sleeved mode. In the reversal rotation operation process, the drill stem on the lower portion and the drill bit can be impacted for operation, and in the forward rotation operation, the drill stem and the drill bit are driven to rotate for operation.
Description
Technical field: [0001] The invention belongs to the technical field of machinery, and in particular relates to an impact drill rod structure for shock and noise reduction for drilling hard layers. Background technique: [0002] The actual requirements of drilling or crushing determine the development characteristics of the current drill bits such as performance and efficiency. In reality, when drilling holes or crushing materials, such as partial road crushing or house demolition in urban areas due to engineering factors When the wall is broken and when the viaduct is built, there are some defects, such as broken roads in the urban area, and the noise is loud and harsh when the wall is broken; Gravity realizes percussion drilling, so its efficiency is not high, it is also difficult to break it into, and the drill bit is easily worn or damaged, so there is an urgent need to develop a drill bit structure or device suitable for actual needs. What's more, with the rapid de...
