Description

Technical Field

[0001] The utility model relates to the technical field of geological exploration, in particular to a rock sampling device. Background Art

[0002] Geological exploration is a survey and research activity that uses various means and methods to survey and detect geology, determine the appropriate bearing layer, and determine the foundation type and calculate the foundation parameters based on the bearing capacity of the bearing layer. Geological exploration generally surveys rocks, soil and other geology. When surveying rocks, it is necessary to sample the rocks to analyze the geological conditions of the location. When sampling rocks, it is generally necessary to use a sampling device to sample.

[0003] In the prior art, there is a rock sample sampling device with a publication number of CN220508470U, which comprises: a fixed frame, a hydraulic cylinder is installed through the top surface of the fixed frame, a motor is installed at the extended end of the hydraulic cylinder, the motor is slidably connected to the fixed frame, and a drill barrel is installed on the power output shaft of the motor; by starting the motor, the power output shaft of the motor drives the drill barrel to rotate, and then by starting the hydraulic cylinder, the extended end of the hydraulic cylinder pushes the motor to move downward, thereby causing the rotating drill barrel to move downward, and then the drill barrel drills into the ground and samples through the drill barrel.

[0004] However, in the above scheme, when sampling, the motor drives the drill barrel to rotate, and the hydraulic cylinder drives the drill barrel to move downward. During this process, the drill barrel cuts the rock to separate the rock sample from the rock body. Dust is generated in the process of cutting the rock. The dust will increase the concentration of particulate matter in the working environment air, resulting in a decrease in air quality, which will further affect the health of the workers. Utility Model Content

[0005] The utility model aims to provide a rock sampling device for geological exploration, which can absorb dust generated during sampling and reduce the impact of dust on the environment.

[0006] To achieve the above-mentioned purpose, a rock sampling device for geological exploration is provided, which comprises: a fixed frame, which is a gantry frame, a fixed plate is arranged at the bottom of the fixed frame, and a first through hole is opened on the fixed plate; a sampling component, which comprises a drill tube slidably arranged on the fixed frame, and the diameter of the drill tube is smaller than the diameter of the first through hole; a dust removal component, which comprises a dust suction head, a connecting pipe, a dust collector, a water tank, an air inlet pipe and a diversion pipe head, a plurality of dust suction heads are arranged and located at the bottom of the fixed plate, a plurality of dust suction heads are arranged around the outside of the first through hole, one end of the connecting pipe is connected with the plurality of dust suction heads, and the other end of the connecting pipe is connected with the dust collector, the water tank is located on the side of the fixed frame, the dust collector is connected with the outer wall of the water tank, an air inlet pipe is arranged in the water tank, one end of the air inlet pipe is connected with the dust collector, the diversion pipe head is located at the bottom of the inner cavity of the water tank, the other end of the air inlet pipe is connected with the diversion pipe head, an air hole is opened on the top of the diversion pipe head, and an air outlet pipe is opened on the top of the water tank.

[0007] The working principle and effect of the above scheme are as follows: when the device is used to sample rocks, the device is placed on the rock, the drill barrel slides downward along the fixed frame, the drill barrel passes through the first through hole and contacts the rock surface, and the rock body and the rock sample can be cut when the drill barrel slides downward, and the rock sample is located in the drill barrel; during this process, dust is generated when the drill barrel cuts the rock, the dust suction head is located on the peripheral side of the drill barrel, the dust suction component works, and the vacuum cleaner is started. The vacuum cleaner can suck the dust generated by the drill barrel cutting the rock into the water tank through the connecting pipe and the dust suction head. During this process, the air containing dust in the connecting pipe enters the diversion pipe head through the air inlet pipe and overflows from the air hole on the top of the diversion pipe head. When the dust-containing air passes through the water tank, the dust therein dissolves in the water, and the air flows out of the water tank from the air outlet pipe.

[0008] By setting up a dust suction component, the dust suction head sucks the dust generated when the drill barrel cuts the rock into the water tank. The dust-containing air forms bubbles at the bottom of the water tank. The bubbles come into contact with water during the floating process. During this process, the water in the water tank can absorb the dust generated when the drill barrel is sampling, thereby further reducing the dust in the working environment and reducing the impact of dust on the environment.
