Description

Technical Field

[0001] This invention relates to the field of drilling and sampling equipment technology, specifically to a geological exploration drilling and sampling device for smart mines. Background Technology

[0002] A smart mine is based on the digitalization and informatization of mines. It proactively senses, automatically analyzes, and rapidly processes information related to mine production, occupational health and safety, technical support, and logistical support. The ultimate goal of building a smart mine is to achieve safe, unmanned, efficient, and clean mines.

[0003] A search revealed a Chinese patent document disclosing a geological exploration drilling and sampling device for smart mines [Application No.: CN202420299624.7]. This geological exploration drilling and sampling device for smart mines includes: a mobile base; a frame fixedly connected to the top wall of the mobile base; a lifting plate slidably connected to the side wall of the frame; a drill rod rotatably connected to the bottom wall of the lifting plate; a drill bit fixedly connected to the other end of the drill rod; a sampler fixedly connected to the side wall of the drill rod; a dust cover fixedly connected to the bottom wall of the mobile base; a dust collection box fixedly connected to the top wall of the mobile base; the interior of the dust collection box is fixedly connected to the interior of the dust cover via a pipe; and an exhaust fan is fixedly connected through the side wall of the dust collection box.

[0004] The sampling device disclosed in this patent can collect dust generated during drilling and sampling by using a fan and a dust collection box. However, the height of the dust cover is fixed and difficult to adjust, and its fit with the ground is not good. Therefore, some dust is easily discharged and affects the surrounding working environment. In addition, the sampler with an open top design will scrape the side wall of the drilled pit when it descends. When the sampler is raised to collect samples, it is difficult to collect a large amount of soil. The small sample size can affect subsequent testing operations. Summary of the Invention

[0005] The purpose of this invention is to provide a geological exploration drilling and sampling device for smart mines. First, the drilling operation is covered by a protective section. Then, the air and dust in the protective cylinder are collected into a collection box by the action of pressure, which reduces the impact of dust flying on the working environment. In addition, soil samples are collected into a hollow cylinder as the sampling section is lifted, for later retrieval.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a geological exploration drilling and sampling device for smart mines, comprising a mobile frame, and further comprising: A lifting assembly is installed on one side of the mobile frame, and the lifting assembly includes a pull plate and a cross plate; A rotating assembly is installed on top of a lifting assembly. The rotating assembly includes a drive unit installed on top of a horizontal plate, a sampling unit located at the bottom of the drive unit, and a protective unit located on the surface of the drive unit. A dust-collecting mechanism, located on the surface of the other side of the mobile frame, can filter dust. The air supply pipe is connected to the dust collection mechanism and the protective unit.

[0007] Preferably, the lifting assembly further includes an electric push rod bolted to the surface of the movable frame. The pull plate is welded to the bottom of the piston rod of the electric push rod and slidably connected to the inner wall of the movable frame. The cross plate is welded to the surface of the piston rod of the pull plate and slidably connected to the surface of the movable frame. The top of the movable frame is provided with a guide member that slides through the cross plate. The guide member 240 not only increases the stability of the movable frame 100, but also allows the cross plate 230 to slide on the surface of the guide member 240, thereby increasing the stability of the cross plate 230 when it is raised or lowered.

[0008] Preferably, the driving unit includes: The motor is welded to the top of the horizontal plate; The recessed component is welded to the bottom of the motor output shaft and detachably connected to the sampling section; The collar has a raised structure on its surface so that the operator can lift the collar 313 upwards to expose the bolt 323 to the outside for removal. The collar slides through the bottom of the motor output shaft.

[0009] Preferably, the sampling unit includes: The drilling component is positioned below the sinking component; The vertical plate is welded to the top of the drilling component and fits against the inner wall of the sinking component; Bolts, threaded connections, are attached to the surface of the sunken component and penetrate the vertical plate; A hollow cylinder is movably fitted onto the surface of the drilling component. An arc-shaped plate is fixedly fitted onto the surface of the hollow cylinder, and a protective part is provided on the surface of the driving part.

[0010] Preferably, the protective part includes: A protective cylinder is movably sleeved on the surface of the motor output shaft. The inner wall of the protective cylinder has a groove, and the arc-shaped groove cooperates with the groove to limit the height of the hollow cylinder. The positioning cylinder has a conical design at the bottom so that the bottom of the positioning cylinder 342 can be inserted into the soil to cover the sampling environment and reduce dust spillage. The positioning cylinder is welded to the bottom of the protective cylinder. A baffle slides through the top of the protective cylinder, and an extension frame is welded to the top of the protective cylinder. The surface of the baffle is slidably connected to the inner wall of the extension frame.

[0011] Preferably, a limiting member is welded to the top of the protective cylinder, the limiting member slides through the horizontal plate, and a first spring and a bellows cover are provided between the protective cylinder and the horizontal plate, the bellows cover being fitted onto the surface of the first spring.

[0012] Preferably, the dust collection mechanism includes: The outer frame is welded to the surface on the other side of the mobile frame; The airbag is fixedly connected to the top of the inner wall of the outer frame and to the pull plate. A collection box is installed on the surface of an outer frame. A vent pipe is provided between the outer frame and the collection box. A filter plate slides through the surface of the collection box. A reinforcing part is provided on the top of the collection box to limit the position of the filter plate.

[0013] Preferably, the reinforcing part includes: Top plate, welded to the top of the collection box; A U-shaped frame slides through the top of the top plate and is fixedly fitted with a connector; both ends of the U-shaped frame slide through the top of the filter plate. The second spring is fitted onto the surface of the U-shaped frame.

[0014] Preferably, the top of the airbag is connected to a short tube that penetrates the outer frame. The vent pipe is connected to the short tube, and a one-way valve is provided on the surface of the short tube. When the airbag 420 is deployed, the negative pressure inside the airbag 420 causes outside air to be injected into the airbag 420 through the vent pipe 430. The outside air is injected through the protective cylinder 341 and discharged into the collection box 440 through the air supply pipe 500, supplying air to the vent pipe 430. After being filtered, the air is discharged into the airbag 420. Dust in the protective cylinder 341 is blocked when it passes through the limiting member 350, thus completing the dust collection. When the airbag 420 is compressed, most of the gas inside it is directly discharged through the one-way valve.

[0015] Preferably, a conical block is welded to the bottom of the drilling component, and auger blades are disposed above the surface of the drilling component, with the auger blades having a design that is wider at the top and narrower at the bottom. Compared with the prior art, the beneficial effects of the present invention are as follows: This invention uses a protective cover to enclose the drilling operation. During the descent of the rotating assembly for sampling, pressure is used to collect air and dust from the protective cylinder into a collection box, reducing dust dispersion. In addition, soil samples are collected into a hollow cylinder as the sampling unit rises for later retrieval. This solves the problems of fixed dust cover height in some current sampling devices, which easily leads to dust dispersion, and the small sample volume of the sampler, which can affect subsequent testing operations.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Please see Figures 1-9A geological exploration drilling and sampling device for smart mines includes a mobile frame 100. A lifting assembly 200 is installed on one side of the mobile frame 100. The lifting assembly 200 includes an electric push rod 210 bolted to the surface of the mobile frame 100. A pull plate 220 is welded to the bottom of the piston rod of the electric push rod 210. A horizontal plate 230 is welded to the surface of the piston rod of the pull plate 220. The pull plate 220 is slidably connected to the inner wall of the mobile frame 100, and the surface of the horizontal plate 230 is slidably connected to the surface of the mobile frame 100. When the electric push rod 210 is activated, the pull plate 220 and the horizontal plate 230 descend simultaneously. The top of the movable frame 100 is provided with a guide member 240. The guide member 240 not only increases the stability of the movable frame 100, but also allows the horizontal plate 230 to slide on the surface of the guide member 240, increasing the stability of the horizontal plate 230 when it is raised or lowered. A rotating assembly 300 is installed on the top of the horizontal plate 230. The rotating assembly 300 includes a drive unit 310 bolted to the top of the horizontal plate 230. A sampling unit 320 is provided at the bottom of the drive unit 310. The drive unit 310 includes a motor 311 welded to the top of the horizontal plate 230. The bottom of the output shaft of the motor 311... The sampling part 320 is detachably connected to the sinking part 312 and is welded to the sinking part 312. The sampling part 320 includes a drilling part 321 with a conical block welded to the bottom and a vertical plate 322 welded to the top of the drilling part 321. A auger blade with a wider top and narrower bottom is provided above the surface of the drilling part 321. The surface of the vertical plate 322 is in contact with the inner wall of the sinking part 312. A bolt 323 is threadedly connected to the surface of the sinking part 312. The bolt 323 penetrates the vertical plate 322. When the bolt 323 is connected to the sinking part 312, it penetrates the vertical plate 322. At this time, the position of the drilling part 321 is... With the position restricted, when the output shaft of the motor 311 rotates, it can drive the drilling component 321 to rotate through the sinker 312. The bottom of the output shaft of the motor 311 has a collar 313 that slides through it. The bottom of the collar 313 contacts the top of the drilling component 321, and the surface of the collar 313 is provided with a protruding structure so that the operator can lift the collar 313 upwards to expose the bolt 323 to the outside and remove it. Based on this, the operator can remove the bolt 323 to disconnect the connection between the sinker 312 and the vertical plate 322, and then remove and move the drilling component 321 to complete the sampling.

[0020] Please see Figures 7-8A hollow cylinder 330 is movably fitted onto the surface of the drilling component 321. An arc-shaped plate is fixedly fitted onto the surface of the hollow cylinder 330. A protective part 340 is provided on the surface of the drive unit 310. The protective part 340 includes a protective cylinder 341 movably fitted onto the surface of the output shaft of the motor 311. A groove is formed on the inner wall of the protective cylinder 341. The arc-shaped groove cooperates with the groove to limit the height of the hollow cylinder 330. A positioning cylinder 342 is welded to the bottom of the protective cylinder 341. The bottom of the positioning cylinder 342 is tapered to facilitate the positioning of the cylinder 342. The bottom can be inserted into the soil to cover the sampling environment and reduce dust spillage. An extension frame 343 is welded to the top of the protective cylinder 341. A baffle 344 slides through the top of the protective cylinder 341. The surface of the baffle 344 is slidably connected to the inner wall of the extension frame 343. When the staff pulls the baffle 344 upward, the baffle 344 removes its obstruction of the protective cylinder 341. At this time, the staff can remove the hollow cylinder 330 and the sampling part 320. Conversely, during the sampling process, the baffle 344 can block the space inside the protective cylinder 341.

[0021] Please see Figures 5-7 To ensure the relative stability of the protective cylinder 341, a limiting member 350 is welded to the top of the protective cylinder 341. The limiting member 350 slides through the horizontal plate 230 and limits the height of the protective cylinder 341 as it descends, preventing it from falling off. The limiting member 350 also guides the protective cylinder 341 as it moves. A first spring 360 is provided between the protective cylinder 341 and the horizontal plate 230. The first spring 360 is sleeved on the surface of the piston rod of the motor 311. Under the elastic force of the first spring 360, the protective cylinder 341 and the positioning cylinder 342 can be pushed downward. A bellows cover 370 is welded to the bottom of the horizontal plate 230. The bottom of the bellows cover 370 is welded to the top of the protective cylinder 341. The bellows cover 370 is sleeved on the surface of the first spring 360 and can cover and protect the first spring 360.

[0022] When the sampling unit 320 descends to collect samples, the protective unit 340 descends accordingly to cover the drilling environment. Simultaneously, a dust collection mechanism 400 is installed on the other side of the mobile frame 100 to collect dust from the protective unit 340. An air supply pipe 500 connects the dust collection mechanism 400 and the protective unit 340. The dust collection mechanism 400 includes an outer frame 410 welded to the other side of the mobile frame 100. An airbag 420 is fixedly connected to the top of the inner wall of the outer frame 410, and the bottom of the airbag 420 is fixedly connected to the top of the pull plate 220. When the pull plate 220 descends, the airbag 420 can be opened, creating a negative pressure inside the airbag 420. A vent pipe 430 is connected to the top of the outer frame 410, and the other end of the vent pipe 430 connects to a collection box 440 installed on the surface of the outer frame 410. A filter plate 450 slides through the surface of the collection box 440. The top of the collection box 440 is provided with a reinforcing part 460 that can limit the position of the filter plate 450. The reinforcing part 460 includes a top plate 461 welded to the top of the collection box 440. A U-shaped frame 462 slides through the top of the top plate 461. A connector 463 is fixedly sleeved on the surface of the U-shaped frame 462. A second spring 464 is sleeved on the surface of the U-shaped frame 462. Both ends of the U-shaped frame 462 slide through the top of the filter plate 450. When the operator pulls the U-shaped frame 462 upward, the two ends of the U-shaped frame 462 that pass through the top of the filter plate 450 move out. At this time, the connector 463 rises with the U-shaped frame 462 and squeezes the second spring 464. After the operator cleans and replaces the filter plate 450, the U-shaped frame 462 and the connector 463 descend under the action of the elastic force of the second spring 464. Both ends of the U-shaped frame 462 pass through the top of the filter plate 450, thereby fixing the position of the filter plate 450.

[0023] When the airbag 420 is deployed, the negative pressure inside the airbag 420 causes outside air to be injected into the airbag 420 through the venting tube 430. The outside air is injected through the protective cylinder 341 and discharged into the collection box 440 through the air supply tube 500, supplying air to the venting tube 430. After being filtered, the air is discharged into the airbag 420. Dust in the protective cylinder 341 is blocked when it passes through the limiting member 350, thus completing the dust collection. The top of the airbag 420 is connected to a short tube that penetrates the outer frame 410. The venting tube 430 is connected to the short tube. A one-way valve is provided on the surface of the short tube. When the airbag 420 is compressed, most of the gas inside it is directly discharged through the one-way valve.

[0024] Working principle: The mobile frame 100 moves to the sampling point. The operator activates the electric push rod 210, causing the pull plate 220 and horizontal plate 230 to descend. The protective cylinder 341 descends accordingly, and the positioning cylinder 342 descends synchronously, either touching or penetrating the ground. At this time, the protective cylinder 341 provides a protective enclosure for the drilling environment. The operator then activates the motor 311. The piston rod of the motor 311 drives the sinking component 312 and the vertical plate 322 to rotate. The sinking component 312 descends continuously while drilling, thus completing the drilling operation. During the drilling process, soil samples collected on the surface of the drilling component 321 can be moved into the hollow cylinder 330 as the drilling component 321 is subsequently lifted. Later, the operator can... Pull the baffle 344 to release its obstruction of the protective cylinder 341, then raise the collar 313 and remove the bolt 323 to take out the hollow cylinder 330 and the drilling part 321 for subsequent collection and sorting of the samples taken out of the drilling part 321. During the descent of the horizontal plate 230, the pull plate 220 descends simultaneously and pulls the airbag 420 to unfold. The air supply pipe 500 injects the air and dust in the protective cylinder 341 into the collection box 440. The filter plate 450 filters the dust. The treated air is injected into the airbag 420 through the ventilation pipe 430. The dust is collected in the collection box 440, which can reduce the occurrence of dust flying and reduce the impact of the drilling and sampling process on the surrounding environment.
