Description

Technical Field

[0002] Existing geotechnical materials are a general term for any kind of rock and soil that make up the earth's crust from the perspective of engineering construction. Geotechnical materials can be subdivided into five categories: hard (hard rock), sub-hard (soft rock), weakly connected, loosely unconnected, and with special composition, structure, state, and properties.

The present invention can also be implemented or applied through other different specific implementations, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0026] It should be noted that the illustrations provided in this embodiment are only used to schematically illustrate the basic concept of the present invention. Therefore, the drawings only show components related to the present invention rather than being drawn according to the number, shape and size of components in actual implementation. In actual implementation, the type, quantity and proportion of each component may be changed arbitrarily, and the component layout may also be more complicated.

[0027] See also Figure 1 In the process of rock and soil sampling in the prior art, there is a problem of rock and soil falling, which requires multiple drilling samplings during actual rock and soil sampling, resulting in relatively low efficiency. In addition, when the existing sampling equipment is actually sampling rock and soil, the drilling head will be exposed, which will be inconvenient during actual transportation. In this regard, the utility model proposes a rock and soil sampling device, including: a frame 10, a drilling part 20, which is rotatably arranged on a lifting mechanism, and the lifting mechanism drives the drilling part 20 to be located on the frame 10 and to rise and fall; a driving part for The drilling unit 20 is driven to rotate on the lifting mechanism and drill the rock and soil; the collecting unit 30 is installed on the drilling unit 20 and moves with the drilling unit 20; a gate 31 is provided on the collecting unit 30, and the gate 31 is used to realize the connection and closing of the collecting unit 30 with the outside world, and the gate 31 presents two states: one is that when the driving unit drives the drilling unit 20 to rotate, the collecting unit 30 is connected with the outside world; the other is that when the driving unit stops, the collecting unit 30 is closed with the outside world.

[0028] In one embodiment, the frame 10 is cylindrical in structure as a whole, and a handle 12 is provided at one end of the frame 10, and the drilling part 20 extends out of the other end of the frame 10. By operating the handle 12 on the cylindrical frame 10 and starting the lifting mechanism, the collecting part 30 protrudes out of one end of the cylindrical frame 10. After the drilling part 20 is installed on the collecting part 30, drilling of rock and soil can be carried out, and the rock and soil remain in the collecting part 30. When the drilling part 20 is drilling, the gate 31 is in an open state, and the rock and soil can enter the collecting part 30. When the drilling part 20 is lifted, the gate 31 is in a closed state, and the rock and soil will not fall from the collecting part 30, so as to reduce the problem of a large number of rock and soil sampling times and improve the sampling efficiency. After the sampling contact, the collecting part 30 can be stored in the frame 10, so that it is smaller in size when moving, which is more convenient.

[0029] In one embodiment, in order to collect rock and soil samples, the collection part 30 is tubular as a whole, the drilling part 20 is installed at one end of the collection part 30, a through hole 32 is provided on the tube wall of the collection part 30, and the gate 31 is provided in the through hole 32, and the gate 31 is assembled to be able to engage with or move away from the through hole 32.

[0030] In one embodiment, as the drilling unit 20 penetrates into the rock and soil, the gate 31 is separated from the through hole 32, so that the collection unit 30 is open, and the rock and soil can enter the collection unit 30 through the gate 31, so that the rock and soil can be collected in real time. When the drilling unit 30 and the collection unit 30 stop drilling, the gate 31 engages with the through hole 32 to prevent the rock and soil from moving out of the through hole 32.

[0031] In a specific embodiment, in order to realize automatic closing and opening of the through hole 32 by the gate 31, a guide frame 311 is provided on the gate 31, and the guide frame 311 and the guide block 312 form a sliding fit along the radial direction of the collection part 30.

[0032] In one embodiment, the gate 31 is actually a counterweight block. When the pipe of the collection part 30 rotates synchronously with the drilling part 20, the centrifugal force generated by the gate 31's own weight causes the gate 31 to move away from the through hole 32, thereby opening the through hole 32. As the drilling part 20 stops, the collection part 30 stops rotating immediately. Under the action of the guide spring 314, the gate 31 is reset, and the gate 31 is pressed against the pipe wall of the through hole 32 to prevent the rock and soil entering the collection part 30 from falling randomly, thereby maximizing the efficiency of rock and soil sampling.

[0033] In one embodiment, the guide spring 314 is normally in a compressed state. When the drilling unit 20 stops rotating, the gate 31 closes the through hole 32 under the pulling force of the guide spring 314 .

[0034] In one embodiment, in order to implement drilling of rock and soil, the drilling part 20 includes a drill bit 21, and the drill bit 21 is generally in the shape of a truncated cone, and the large-sized end of the drill bit 21 is connected to the pipe end of the collection part 30. The outer wall of the drill bit 21 is provided with a drilling groove, and the drill bit 21 is connected to the pipe end of the collection part 30 through a fixing screw 211.

[0035] In one embodiment, one end of the drilling part 20 is sleeved on the pipe end of the collecting part 30, and a radial fixing nut 211 is arranged on the outer wall of the drill bit 21 of the drilling part 20. The fixing nut 211 can realize the fixed connection between the collecting part 30 and the drilling part 20. When the drilling sampling is completed and transportation is required, the fixing nut 211 is removed to separate the drilling part 20 from the collecting part 30, so that the collecting part 30 can be extended into the frame 10 without taking up space, which is convenient for transportation.

[0036] In one embodiment, in order to crush the rock and soil at the drilling position and facilitate the crushed rock and soil to enter the tube cavity of the collection part 30, the drilling part 20 also includes a crushing ring 22, which is fixed on the tube wall of the collection part 30 and close to the drill bit 21.

[0037] In order to drive the collection part 30 and the drilling part 20 to extend into the rock and soil, the lifting mechanism includes a lifting frame 41, the drilling part 20 is rotatably connected to the lifting frame 41, the frame 10 is provided with a guide rail 11, the guide rail 11 is parallel to the length direction of the drilling part 20, the lifting frame 41 and the guide rail 11 are slidably matched, and the lifting frame 41 is also provided with a lifting nut 411, the lifting nut 411 is matched with the lifting screw 42, the lifting screw 42 is parallel to the guide rail 11, one end of the lifting screw 42 is connected to the lifting motor 43, and the lifting motor 43 is fixed to the frame 10.

[0038] In one embodiment, by starting the lifting motor 43 , the lifting frame 41 can be moved along the guide track 11 , thereby driving the collection unit 30 and the drilling unit 20 .

[0039] In one embodiment, in order to implement high-speed rotation of the drilling part 20, the driving part includes a driving motor 51 arranged on the lifting frame 41, and a reinforcing plate 52 is arranged on the pipe body of the drilling part 20. The drilling part 20 and the reinforcing plate 52 form a rotational fit, and the reinforcing plate 52 is connected to the lifting frame 41 through an extension plate.

[0040] By cooperating with the reinforcement plate 52 and the tube body of the collection part 30 , the collection part 30 can be reliably supported in the axial direction, thereby avoiding the problem of bending and deformation of the tube body of the collection part 30 when the drilling part 20 is drilling rock and soil.

[0041] In summary, rock and soil can be collected by providing the collection part 30 and the drilling part 20. During the collection process, the rotation of the drilling part 20 can be controlled to make it more efficient when collecting rock and soil. The drilling part 20 can be replaced when collecting rock and soil of different hardness, so that it can be more effective when drilling holes in rock and soil. A gate 31 is provided on the collection part 30, so that rock and soil can enter the collection part 30 when collecting rock and soil, and the gate 31 can block the collection part when the drilling part 20 and the collection part 30 stop rotating, so as to prevent rock and soil from leaking out of the collection part. By providing a lifting mechanism, the length of the collection part 30 extending to the outer shell can be fixed during sampling, and the collection part can be retracted into the frame 10 after the sampling contact, so that it is smaller in size when moving, so that it can be more convenient. The sampling device can solve the problem of rock and soil leaking out of the sampling tube in the prior art, so as to reduce the problem of a large number of rock and soil sampling times and improve the sampling efficiency.
