Moreover, the thickness of the teeth on the existing saw blades is the same. When cutting sandstones with different hardness and thickness, different saw blades need to be replaced, which is inconvenient to operate, and the length of the saw blades is fixed and cannot be adjusted. It cannot be adjusted according to personal operating habits. Adjustment, which affects the convenience of its use

Embodiment Construction
[0013] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.
[0014] Such as figure 1 As shown, a high-efficiency adjustable saw blade for loose sandstone on-site sampling includes a saw blade body 1 and a clamping part 2. The saw blade body 1 is fixedly connected to the clamping part 2. The upper and lower sides of the saw blade body 1 are respectively provided There are upper sawtooth 3 and lower sawtooth 4, and the thickness of the upper sawtooth 3 and the lower sawtooth 4 are different. The clamping part 2 is provided with two waist-shaped installation holes 5 in the horizontal direction, and the installation holes 5 are provided at intervals. Several limit protrusions 6, by setting upper sawtooth 3 and lower sawtooth 4 of different thickness, can choose to use upper sawtooth 3 or lower sawtooth 4 to cut...

Abstract
The invention discloses a high-efficiency adjustable type saw blade for loose sandstone on-site sampling; the saw blade comprises a saw blade body and a clamping part; the saw blade body is fixedly connected with the clamping part; upper sawteeth and lower sawteeth are respectively arranged on the upper side and the lower side of the saw blade body, and the coarseness or fineness of the upper sawteeth and the coarseness or fineness of the lower sawteeth are different; two round-waist mounting holes in horizontal direction are formed in the clamping part; a plurality of limit projections are arranged on the mounting holes at intervals; through arrangement of the upper sawteeth and the lower sawteeth with different coarseness or fineness, the upper sawteeth or the lower sawteeth are selected for cutting according to different hardness, coarseness or fineness and thickness of workpieces, so that the adaptability is strong, the saw blade wear is reduced, premature fatigue cracking of tooth tips is avoided, and the service life is prolonged; the arranged round-waist mounting holes can be convenient for people to adjust the extension length of the saw blade body according to their own habits, so that the use convenience is improved.
Description
technical field [0001] The invention relates to the field of rock mass sample strength testing and evaluation research in geotechnical engineering, and specifically relates to a high-efficiency adjustable saw blade for on-site sampling of loose sandstone. Background technique [0002] Rock mass strength is an important parameter in rock mass engineering design. Many problems in the field of geotechnical engineering require rock mass strength analysis and testing. Sampling is an indispensable and frequent work in rock mass strength analysis and testing. The traditional rock and soil sampling method is the core drilling method, but for loose sandstone lacking cement, due to its low cohesion, it is impossible to obtain a complete core when sampling with the core drilling method, and a manual cutting method is used instead . The manual cutting method adopts various forms of cutting devices, such as hand-held saw blades and the like. When using conventional saw blades to cut l...
