Description

A rock and soil sampling device

Technical Field

The invention relates to the technical field of soil sampling equipment, and in particular to a rock and soil sampling device.

Background technique

The electric soil sampler is a tool that uses an electric rotating mechanism to drive a hollow circular drill bit to drill rock and soil. It is currently a more common sampling device. The hollow circular drill bit in the traditional sampling device generally does not have a structure for quickly removing rock and soil, so after the rock and soil sampling is completed, it is necessary to rely on manual use of other tools to difficultly poke out the sample in the drill bit. Since the rock and soil fill the inside of the drill bit, this will not only make it more difficult to remove the sample, but also easily disperse the sample, resulting in mixing of rock and soil samples at different levels, which adds trouble to subsequent testing work.

Therefore, a rock and soil sampling device is proposed to solve the above problems.

Summary of the invention

The present invention achieves the above-mentioned purpose through the following technical scheme, a rock and soil sampling device, including: an electric soil sampler; a bulldozer, the bulldozer that can quickly push rock and soil out from the inside of the electric soil sampler is installed at the upper end of the electric soil sampler, and the lower end of the bulldozer penetrates into the interior of the electric soil sampler.

Preferably, the bulldozer includes a piston rod slidably connected to the inside of the electric earth extractor, the upper end of the piston rod passes through the outside of the electric earth extractor, the surface of the piston rod is plugged with a positioning mechanism fixedly connected to the electric earth extractor, the upper end of the piston rod is plugged with a T-shaped adjusting rod, the inside of the T-shaped adjusting rod is fixedly connected with a connecting mechanism that is engaged with the piston rod. By setting up the bulldozer, when the staff needs to take out the rock and soil inside the electric earth extractor, the staff only needs to connect the T-shaped adjusting rod with the piston rod through the connecting mechanism, and then the staff unlocks the positioning mechanism so that the piston rod loses resistance. The staff can then push down the piston rod through the T-shaped adjusting rod, and the piston rod pushes out the rock and soil inside the electric earth extractor. This not only enables the staff to take out the sampled rock and soil conveniently and quickly, but also does not stir up the samples, resulting in the mixing of rock and soil samples at different levels, thereby reducing the difficulty of subsequent detection work.

Preferably, the upper end of the piston rod is provided with a card slot that is plugged into the T-shaped adjusting rod, the interior of the piston rod is provided with positioning grooves that are distributed in an annular shape and are all connected to the card slots, the upper end of the T-shaped adjusting rod is provided with a first mounting groove, the surface of the T-shaped adjusting rod is provided with second mounting grooves that are distributed in an annular shape and are all connected to the first mounting groove, the connecting mechanism includes a connecting rod slidably connected to the inside of the first mounting groove, the surface of the connecting rod is fixedly connected with an annularly distributed spring sheet, one end of the spring sheet away from the connecting rod penetrates into the inside of the second mounting groove, one end of the spring sheet away from the connecting rod is fixedly connected with a mounting plate that is slidably connected to the second mounting groove, and one end of the mounting plate away from the spring sheet is fixedly connected with The positioning blocks respectively engaged with the adjacent positioning grooves can make the T-shaped adjusting rod and the grooves tightly plugged together by setting a connecting mechanism, so that the T-shaped adjusting rod can drive the piston rod more stably, and when the staff does not need to use the T-shaped adjusting rod, the staff only needs to pull up the connecting rod, and the connecting rod pulls all the spring pieces at the same time. The spring pieces drive the positioning block to separate from the positioning groove through the mounting plate and retract into the inside of the second mounting groove. At this time, the T-shaped adjusting rod loses connection with the groove, and the staff can remove the T-shaped adjusting rod. This can not only reduce the obstruction of the T-shaped adjusting rod to the staff when taking rock and soil samples, but also reduce the volume occupied by the electric soil sampler when it is stored, making it more convenient for the staff to carry it when going out.

Preferably, the cross-sectional shapes of the positioning block and the adjacent positioning groove are both matching right-angled triangles, and the inclined surfaces of the positioning block and the adjacent positioning groove are both facing downward. When the staff inserts the T-shaped adjustment rod into the slot, since the inclined surface of the positioning block is facing downward, when the inclined surface of the positioning block contacts the slot, the slot can squeeze the positioning block back into the second installation slot to ensure that the T-shaped adjustment rod can normally penetrate into the slot without manual adjustment by the staff, thereby reducing the connection difficulty for the staff.

Preferably, one side of the inner wall of the second mounting groove is slidably connected with a uniformly distributed guide rod, one end of the guide rod passes through the mounting plate and is fixedly connected to the other side of the inner wall of the second mounting groove, and the guide rod can limit the moving trajectory of the mounting plate to ensure the normal operation of the mounting plate and the positioning block.

Preferably, a spring is sleeved on the surface of the guide rod, and the spring is fixedly connected between the mounting plate and the second mounting slot. The spring is always in a compressed state. The spring can make the positioning block and the positioning slot more tightly connected to reduce the probability of the T-shaped adjustment rod loosening or falling off during use.

Preferably, a plug-in groove is provided on the surface of the piston rod, and the positioning mechanism includes a connecting ring sleeved on the surface of the piston rod, the lower end of the connecting ring is fixedly connected to the electric soil extractor, and a positioning pin is plugged into the surface of the connecting ring, one end of the positioning pin passes through the connecting ring and is plugged into the plug-in groove. By setting up the positioning mechanism, when the staff is not using the piston rod, the positioning pin can lock the piston rod firmly inside the electric soil extractor through the connecting ring and the plug-in groove, so as to reduce the influence of the piston rod on the normal soil extraction of the electric soil extractor.

The beneficial effects of the present invention are:

1. By setting up a bulldozer, when the staff needs to take out the rock and soil inside the electric soil extractor, the staff only needs to connect the T-shaped adjustment rod with the piston rod through the connecting mechanism, and then the staff unlocks the positioning mechanism to make the piston rod lose resistance. The staff can push down the piston rod through the T-shaped adjustment rod, and the piston rod pushes out the rock and soil inside the electric soil extractor. This not only enables the staff to take out the sampled rock and soil conveniently and quickly, but also does not stir up the samples, resulting in the mixing of rock and soil samples at different levels, thereby reducing the difficulty of subsequent detection work;

2. By setting up a connecting mechanism, the T-shaped adjusting rod and the card slot can be tightly plugged together, so that the T-shaped adjusting rod can drive the piston rod more stably, and when the staff does not need to use the T-shaped adjusting rod, the staff only needs to pull up the connecting rod, and the connecting rod pulls all the springs at the same time. The springs drive the positioning block to separate from the positioning slot through the mounting plate and retract into the second mounting slot. At this time, the T-shaped adjusting rod loses connection with the card slot, and the staff can remove the T-shaped adjusting rod. This can not only reduce the obstruction of the T-shaped adjusting rod to the staff when taking rock and soil samples, but also reduce the volume occupied by the electric soil sampler when it is stored, making it more convenient for the staff to carry it when going out.
