Direct-push soil sampling drilling machine

Abstract

The invention belongs to the technical field of mechanical equipment, and particularly relates to a direct-push soil sampling drilling machine. The direct-push soil sampling drilling machine comprisesa mast assembly, a driving assembly and a drilling tool, wherein the driving assembly comprises a chassis and an operating room; the chassis comprises a walking crawler belt, a driving motor and walking wheels; at least two groups of walking wheels are provided; each group of walking wheels comprises at least two walking wheels; the crawler belt is meshed with the walking wheels; the operating room is arranged above the chassis; the operating room is used for controlling the advancing direction and the advancing speed of the chassis; the mast assembly comprises a mast upper section and a mastlower section; the bottom of the mast lower section is hinged to the front side of the operating room; the top of the mast lower section is hinged to the bottom of the mast upper section; the top ofthe mast upper section is connected with a hoisting device; the hoisting device is connected with a drilling rod through a steel rope; an oil cylinder is arranged in the drilling rod; and the lower side of the drilling rod is connected with the drilling tool. The invention aims to provide the direct-push soil sampling drilling machine which can be suitable for soil drilling of slopes of various heights during soil sampling, and is convenient to transport and work.

Description

technical field [0001] The invention belongs to the technical field of mechanical equipment, and specifically relates to a direct-push soil sampling drilling rig. Background technique [0002] At present, when the rotary drilling rig is configured with the CFA method, it is usually implemented on models below 280, and it is difficult to achieve a large drilling depth increase on a small drilling rig according to the conventional drilling rig classification. [0003] CAF usually completes pile hole construction with large drilling depth by increasing the height of the mast or changing to a larger model. [0004] A rotary drilling rig with a publication number of CN203639040U, a lifting device, a lifting system, and a rotary drilling rig with the same, include a fixed pulley block and a movable pulley block that are arranged oppositely on the upper and lower sides, and a fixed pulley block connected to the movable pulley block and the fixed pulley block. The telescopic oil cy...

AI Technical Summary

Problems solved by technology

[0006] 1) The height of the mast must be high enough, so it increases the instability of the drilling rig even more

[0007] 2) The oblique support adopts a non-foldable method, which is troublesome in transportation and work

[0008] 3) It is inconvenient to advance on the road with uneven ground surface;
