Problems solved by technology

[0003] At present, the fully hydraulic core sampling drilling rigs on the market have the disadvantages of low automation. During the drilling process, the drill pipes need to be manually installed and disassembled one by one, resulting in a large amount of labor, low sampling efficiency, harsh working environment, and poor safety.

Embodiment 1

[0033] A feeding mechanism for a core sampling drilling rig, specifically a feeding mechanism capable of transporting drill pipe 4 and casing 5 at the same time, including a storage mechanism 1, a support mechanism 2 and a delivery mechanism 3, see Figure 1-Figure 3 ,Details are as follows:

[0034] The storage mechanism 1 includes a body, a housing chamber group and a jacking assembly, the housing chamber group is separated by partitions arranged inside the body, and the housing chamber group includes four housing chambers 1.1 arranged side by side, two of which are housing chambers. The drill pipe accommodation chamber A1 of the drill pipe, and the other two are casing chamber accommodation chambers A2 for accommodating the casing pipe. The drill pipe accommodation chamber A1 includes a material outlet 1.11 through which a drill pipe can pass, and the casing accommodation chamber A2 includes a material outlet 1.11 through which a casing pipe can pass. The jacking assembly ...

Abstract

The invention provides a feeding mechanism for a core sampling drill. The feeding mechanism includes a storage mechanism, a supporting mechanism and a conveying mechanism, the storage mechanism comprises accommodating cavities and jacking singletons, each accommodating cavity includes a material outlet, and each jacking singleton is arranged below the corresponding accommodating cavity and used for jacking materials in the corresponding jacking cavity; the supporting mechanism includes supporting singletons, each supporting singleton is arranged at the material outlet position and used for controlling the closing and opening of the material outlet, and the conveying mechanism comprises a conveying power source, a material supporting frame and a supporting guide rail; the material supporting frame is provided with clamping groove groups and a sliding part, the clamping groove groups are located below the accommodating cavities, so that the materials in the accommodating cavities can fall into clamping grooves in the clamping groove groups; the conveying power source is used for driving the material supporting frame to move back and forth on the supporting guide rail to realize material conveying. The feeding mechanism for the core sampling drill has the effects that the device structure is simplified, the automation feeding is realized (especially automation alternate conveyingof two or more materials), the labor intensity is reduced, and the construction efficiency and construction safety are improved.

Description

technical field [0001] The invention relates to the technical field of geological engineering drilling equipment, in particular to a feeding mechanism for a core sampling drilling rig. Background technique [0002] With the rapid development of the economy, there is an increasing demand for the detection of architectural geological structures and underground mineral resources. In the field of geological engineering drilling and survey equipment, fully hydraulic core sampling drilling rigs are the main force of current exploration equipment. [0003] At present, the fully hydraulic core sampling drilling rigs on the market have the disadvantages of low degree of automation. During the drilling process, drill pipes need to be installed and disassembled one by one manually, resulting in a large amount of labor, low sampling efficiency, harsh working environment and poor safety. [0004] Therefore, it is of great significance to design a device that can automatically feed mater...
