Drilling and sampling device for road construction
The invention relates to the field of sampling, in particular to a drilling and sampling device for road construction. The sampler comprises a frame and a sampling assembly arranged on the frame, the sampling assembly comprises a drilling cylinder and an inner cylinder, a plurality of drilling tools are hinged to the lower end of the drilling cylinder, the inner cylinder is coaxially inserted into the drilling cylinder, the inner cylinder is of a grating structure and comprises a first cylinder body and a second cylinder body, and a film is arranged in the inner cylinder. When a road surface part is drilled, the drilling tool is in a horizontal state, the contact area between the drilling tool and the road surface is large, large cutting supporting force can be kept, a drilling barrel is prevented from being stressed and deformed, when a roadbed part is drilled, the drilling tool is in an upright state, the contact area between the drilling tool and the roadbed is small, the cutting speed is increased, and the cutting efficiency is improved, so that different drilling requirements are met; meanwhile, when the roadbed part is cut, the inner cylinder is inserted into the roadbed in advance to support the roadbed, after drilling is finished, the thin film is pulled open to wrap the sample core, it is guaranteed that the distribution state of all layers of structures of the sample core is accurate, and the authenticity of the sample is guaranteed.
本发明涉及取样领域，具体涉及一种道路施工钻孔取样装置。其包括车架和设置于车架的取样组件，取样组件包括钻筒和内筒，钻筒下端铰接有若干钻刀，内筒同轴插装于钻筒内部，内筒为格栅结构，内筒包括第一筒体和第二筒体，内筒内部设置有薄膜。本发明在钻取路面部分时，钻刀处于水平状态，钻刀与路面的接触面积大，能够保持较大的切削支持力，防止钻筒受力变形，钻取路基部分时，钻刀处于直立状态，钻刀与路基的接触面积小，加快切削速度，提高切削效率，以此适应不同钻取需求，提高样本质量，同时在切削路基部分时，内筒提前插入路基对路基起到支护作用，钻取结束后，薄膜拉开包裹样芯，保证样芯各层结构的分布状态准确，确保样本真实性。
