Embodiment Construction

[0029] The present invention will be described in detail below in conjunction with specific embodiments.

[0030] Such as Figure 1 to Figure 3 As shown, the present invention relates to a small-scale drilling and coring machine for laboratory use, including a base 1, a hydraulic lifting device 2, a hollow vertical arm 3, a motor 5, a chassis 8, a drilling tool box 9, and a moving control device for a test piece disk 10. Wherein the vertical arm 3 is fixed on the base through bolt connection, and the bottom of the hydraulic lifting device 2 is fixed on the base through bolt connection. The motor is fixed on the hollow vertical arm 3 through the supporting plate 4 and the steel belt 6, and the upper part of the motor is connected to one end of the cabinet 8 through a bearing 72. The drilling tool box 9 is fixed on the other end of the cabinet 8 .

[0031] The base 102 of the specimen disk movement control device 10 is connected to the base 1 through a horizontal ball 101, an...

Abstract

The invention discloses a small multi-drill-bit vertical drilling and core-picking machine for a laboratory. The machine comprises a base (1), a hydraulic lifting device (2), a hollow vertical arm (3), a motor (5), a case (8), a drilling tool case (9) and a test piece disc movement control device (10); the vertical arm (3) is fixed on the base (1), and the bottom of the hydraulic lifting device (2) is fixed on the base (1), and the motor is fixed on the hollow vertical arm (3); the traditional mode that a single rock sample is taken out by one time lower cutter is changed into the mode that five drill bits are utilized for simultaneously picking cores, a main driving bar drives four secondary driving bars to work, the switching of the big and small drill bits can be realized, the sufficient sampling is guaranteed, a belt and a belt pulley adopt a sawtooth engagement and connection driving mode so as to guarantee the smooth driving.

Description

technical field [0001] The invention relates to the technical field of laboratory equipment, in particular to a small multi-drill vertical drilling and coring machine for laboratories. Background technique [0002] When performing rock mechanics experiments in the field of geotechnical engineering, rock blocks need to be processed into cylindrical standard specimens, and coring machines are often used for equal-diameter drilling and coring. Most of the existing laboratory drilling coring machines are large in size, heavy and difficult to operate. [0003] Therefore, there are defects in the prior art and need to be improved. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a small multi-drill vertical drilling and coring machine for laboratory use in view of the deficiencies in the prior art. [0005] Technical scheme of the present invention is as follows: [0006] A small drilling and coring machine for labor...
