Description

Technical Field

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

[0002] Geological exploration is a scientific investigation and technical operation activity carried out to find and evaluate underground resources such as minerals, oil and natural gas. The process of geological exploration usually requires the use of a soil sampler, which is a tool used for soil sampling. It is used to collect soil samples from the ground or underground for soil composition analysis.

[0003] When the soil sampler is in use, it is first necessary to dig a pit of appropriate depth at a predetermined sampling point, and insert the soil sampler into the soil until the required depth is reached. Then the soil sample is stably taken out to ensure the integrity and representativeness of the sample. For example, the Chinese utility model patent with publication number CN217758677U discloses a geotechnical engineering survey soil sampler, which includes a cross bar, a fixed rod is provided at the bottom end of the cross bar, a cylinder is provided at the bottom end of the fixed rod, a push plate is slidably provided inside the cylinder, and a connecting rod is passed through the cross bar, and the connecting rod is passed through the inner cavity of the cylinder and fixedly connected to the push rod. When the cylinder is inserted into the soil, the push plate contacts the soil and slides up to the inner top of the cylinder, so that the soil can enter the cylinder. When the sampling is completed, the push plate is pressed down, and the push plate is subjected to the force to push the soil out of the inside of the cylinder.

[0004] The inventors found during implementation that the existing soil sampler has no supporting structure during the sampling process, the sampling is not stable enough, the sampler will shake and shift position, which increases the difficulty and inconvenience of soil sampling operations and reduces the efficiency of soil sampling in geological exploration.

[0007] Furthermore, two handles are provided, and the two handles are symmetrically arranged on both sides of the vertical tube, and the axes of the two handles are perpendicular to the axis of the vertical tube; thereby, the operator's use feeling can be improved.

[0008] Furthermore, both handles are covered with rubber sleeves, which can provide an anti-slip function.

[0009] Furthermore, the bottom of the sampling tube is an arc-shaped structure; thereby, the sampling tube can be more easily broken through the soil and inserted into the soil, thereby improving the soil sampling efficiency.

[0010] Furthermore, the bottom of the sampling tube is a serrated structure; thereby, the sampling tube can more easily break the soil and be inserted into the soil, thereby improving the soil sampling efficiency.

[0011] Furthermore, the push block is slidably arranged in the sampling tube, and the diameter of the push block is adapted to the diameter of the inner cavity of the sampling tube; thereby, when the push block moves downward, all the soil in the sampling tube can be pushed out, thereby reducing the residual soil in the sampling tube.

[0012] Furthermore, the pedal part includes a positioning sleeve nested in the outer periphery of the vertical tube, a fixing bolt is penetrated through one side of the positioning sleeve, and the top of the fixing bolt can press the outer wall of the vertical tube; a pedal is fixed to the other side of the positioning sleeve.

[0013] Furthermore, a spring is arranged between the vertical tube and the push handle of the push rod, the spring is sleeved on the outer circumference of the push rod, and the length of the spring is not less than the length of the sampling tube; when the push block pushes the soil in the sampling tube out, the spring is in a compressed state, so under the action of the spring, the push rod and the push block can automatically reset.

[0022] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0023] The utility model discloses a soil sampling device for geological exploration, which comprises a vertical tube 1, a handle 2 is arranged at the upper end of the vertical tube 1, and a sampling tube 3 is fixed at the bottom end of the vertical tube 1. When using the device to sample soil, the handle 2 needs to be held and the sampling tube 3 needs to be inserted into the soil.

[0024] A push rod 6 is provided inside the vertical tube 1. The radial dimension of the push rod 6 is smaller than the inner diameter of the vertical tube 1, so that the push rod 6 can slide inside the vertical tube 1. The length of the push rod 6 is greater than the length of the vertical tube 1. The bottom end of the push rod 6 extends into the inside of the sampling tube 3, so that the bottom end of the push rod 6 can be moved up and down in the sampling tube 3 by manipulating the top end of the push rod 6. Figure 2 As shown, a push handle 61 is installed at the top of the push rod 6, and the push handle 61 can be easily operated manually to make the push rod 6 move up and down along the vertical tube 1. A push block 62 is connected to the bottom end of the push rod 6, and when the push block 62 moves downward under the drive of the push rod 6, the soil sample in the sampling tube 3 can be pushed out.

[0025] In this embodiment, if Figure 1 , Figure 2 As shown, a supporting portion and a pedal portion are also installed at the bottom of the vertical tube 1.

[0026] The support part includes a sleeve 4, a mounting frame 41 and a bracket 42. The sleeve 4 is nested in the outer periphery of the vertical tube 1, and the inner diameter of the sleeve 4 is larger than the outer diameter of the vertical tube 1, so that the support part can slide up and down along the vertical tube 1. When the sampling tube 3 is inserted into the soil for sampling, the support part can be kept fixed relative to the ground, thereby playing a supporting role.

[0027] The mounting frame 41 is located outside the sampling tube 3. The upper end of the mounting frame 41 is fixedly connected to the outer periphery of the sliding sleeve 4, and the lower end of the mounting frame 41 is fixed to the bracket 42. In this embodiment, the bracket 42 is annular, and in other embodiments, the bracket 42 can be a polygonal frame or can be provided with an opening. The bracket 42 can increase the contact area between the support portion and the ground, so that the process of inserting the sampling tube 3 into the soil is more stable.

[0028] When using the device to collect soil, the sampling tube 3 needs to be aligned with the soil collection position first, and then the handle 2 is held to apply force downward. In this process, in order to facilitate the operator to apply force, two handles 2 are provided, and the two handles 2 are symmetrically arranged on both sides of the vertical tube 1, and the axes of the two handles 2 are perpendicular to the axis of the vertical tube 1. In addition, a rubber sleeve 21 is also provided on the handle 2, which can play an anti-slip role.

[0029] In this embodiment, the bottom of the sampling tube 3 is an arc-shaped structure. In other embodiments, the bottom of the sampling tube 3 may also be a sawtooth structure. When the bottom of the sampling tube 3 is a sawtooth structure or an arc-shaped structure, the bottom of the sampling tube 3 can more easily break the soil and extend into the soil, thereby improving the soil sampling efficiency.

[0030] When the sampling tube 3 is inserted into the soil, the soil will exert an upward force on the push block 62 in the sampling tube 3, so that the push block 62 moves upward relative to the sampling tube 3. When the sampling tube 3 completes soil sampling, the push block 62 is located at the top of the inner cavity of the sampling tube 3. Then, by pushing the push rod 6, the push block 62 can move along the sampling tube 3 and push out the soil sample. The diameter of the push block 62 is matched with the diameter of the inner cavity of the sampling tube 3, so that the push block 62 can push out all the soil in the sampling tube 3 during the downward movement, thereby reducing the residual soil in the sampling tube 3.

[0031] On the other hand, the treading part is also installed on the outer circumference of the vertical pipe 1. When inserting the sampling tube 3 into the soil, the user can apply force to the treading part, thereby facilitating the operation.

[0032] Specifically, the pedal part includes a positioning sleeve 5 embedded in the outer circumference of the vertical tube 1, one side of the positioning sleeve 5 is provided with an internal thread, and a fixing bolt 51 is installed in the internal thread. When the fixing bolt 51 is tightened, the top of the fixing bolt 51 can press the outer wall of the vertical tube 1, thereby fixing the pedal part and the vertical tube 1 relatively. A pedal 52 is fixed to the other side of the positioning sleeve 5, and the pedal 52 extends along the radial direction of the vertical tube 1. By stepping on the pedal 52, it is convenient for the operator to step on it, so that the sampling tube 3 can be inserted into the soil faster.

[0033] In addition, a spring 63 is provided between the upper end of the vertical tube 1 and the push handle 61 of the push rod 6. The spring 63 is sleeved on the outer circumference of the push rod 6, and the length of the spring 63 is not less than the length of the sampling tube 3. When the push block 62 pushes the soil in the sampling tube 3 out, the spring 63 is in a compressed state, so under the action of the spring 63, the push rod 6 and the push block 62 can automatically reset, thereby facilitating the use of the device.
