Description

Technical Field

[0001] This invention relates to the field of geological exploration equipment technology, and in particular to a geological sampling device for mine roadways. Background Technology

[0002] During ore mining, it is necessary to sample and test the geological composition of the mine to analyze its main components. Current sampling methods primarily involve excavating geological layers to a certain depth and then sampling geological materials within those layers for testing.

[0003] Currently, there are various ore sampling devices based on the grooving method. For example, Chinese patent CN212458912U discloses a grooving sampling device for rock walls in mine geological exploration. This device is not only easy to move and carry, but also has a protective structure for the cutting tool to prevent injury to the human body during movement or carrying. However, this device uses a single cutter to cut the ore, resulting in low sampling efficiency; moreover, the device requires manual control of the cutting range, and the angle and height of the cutter cannot be mechanically adjusted, resulting in low control precision and time-consuming and labor-intensive operation. In contrast, Chinese patent CN221630995U discloses a grooving sampling device for geological and mineral exploration and mapping, which adopts a double-cutter structure, and the distance, height, and tilt angle of the two cutters are all adjustable. This device improves sampling efficiency with higher control precision and has greater applicability. However, this device still has several drawbacks: it requires manual handling; it lacks the function of tapping and collecting geological samples; the cutter is not protected, which can easily cause accidental injury; and the adjustment mechanism has many complex components.

Detailed Implementation

[0034] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0035] In the description of this invention, it should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0036] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped", "sleeved / connected", "connected", etc., should be interpreted broadly. For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.

[0037] like Figures 1 to 8 As shown in the figure, this invention provides a geological sampling device for mine roadways (hereinafter referred to as "the device"), including a base plate 1, a pushing module 2, a sliding frame 3, a cutting module 4, an installation and positioning module, a striking module 7, and a collection module 9. Generally, the pushing module 2 is fixed to the base plate 1, driving the sliding frame 3 to slide along the length of the base plate 1. The cutting module 4 and the striking module 7 are movably mounted on the sliding frame 3 to cut and strike the rock. The installation and positioning module is movably connected to the cutting module 4 to adjust the working width and angle of the cutting module 4. The collection module 9 is used to collect the knocked-down rock samples. The specific structure and connection relationships of the above components are described in detail below with reference to the figures.

[0038] like Figures 1-4As shown, the base plate 1 is rectangular, and several slide rails 11 are arranged parallel to each other along its length at its top. The pushing module 2 includes a first end plate 21, a first motor 22, and a first lead screw 23. The first lead screw 23 is the transmission rod described in the claims. The first end plate 21 is vertically fixed to the top of the base plate 1 and is located at one end of the slide rail 11. The first motor 22 is fixed to the first end plate 21 and connected to the first lead screw 23 at its output end. The extension direction of the first lead screw 23 is parallel to the slide rail 11. The sliding frame 3 is provided with several support columns 31 and limiting blocks at its bottom. The support columns 31 are located in the slide rail 11 to support the sliding frame 3. The limiting blocks are sleeved in the extension direction of the first lead screw 23 and are threadedly engaged with the first lead screw 23. In this way, when the first motor 22 is turned on, the sliding frame 3 can be driven to reciprocate along the extension direction of the slide rail 11 through the reversing transmission between the first lead screw 23 and the limiting part 32. Furthermore, to improve stability, the pushing module 2 also includes several columns 24 and guide rods 25. The columns 24 are vertically fixed to the top of the base plate 1, and the guide rods 25 are fixed at the top. The guide rods 25 are also parallel to the extension direction of the slide rail 11 and pass through a portion of the limiting part 32 to guide the sliding frame 3. It is easy to understand that in other embodiments, the limiting part 32 mentioned above can also be the support column 31. In a further functional upgrade, as an equivalent alternative to this embodiment, in other embodiments, the combination of the first motor 22 and the first lead screw 23 can be replaced by an electric push-pull rod structure. One end of the push-pull rod structure is vertically fixed to the first end plate 21, and the other end is vertically fixed to the support column 31 or the limiting part 32, and through axial extension and contraction, it drives the sliding frame 3 to slide along the extension direction of the slide rail 11.

[0039] The sliding frame 3 also includes a mounting plate 33, a U-shaped portion 34 extending from the mounting plate 33, and a side plate 35 vertically fixed to the top of the mounting plate 33. Figure 1 As shown, the guide rod 25 extends through the second end plate 341 of the U-shaped portion 34 and engages with the latter radially for a limiting fit. The two side plates 35 are arranged opposite each other along the width direction of the base plate 1, that is, perpendicular to the track.

[0040] The cutting module 4 includes a housing 41, a second motor 42, and a saw blade 43. Two housings 41 are arranged opposite each other along the width direction of the base plate 1, meaning that both housings 41 are parallel to the side plate 35. Two second motors 42 are respectively vertically fixed to the outer sides of the housings 41, and their output ends extend into the housings 41, where they are fixedly connected to the saw blade 43. Preferably, as shown... Figure 5As shown, the casing 41 forms a relatively sealed cavity 412 internally through a sealing plate 411. The cavity 412 contains coolant 413 to cool the saw blade 43. A U-shaped suction duct 414 is provided on the outer edge of the cavity 412. The suction duct 414 is connected to a vacuum cleaner via a connecting pipe 415 to purify the air during sampling. A metal filter screen is installed at the opening of the suction duct 414 to prevent large stones from entering. Several heat dissipation fins 416 are inserted between the cavity 412 and the suction duct 414, utilizing the airflow in the suction duct 414 to remove heat from the coolant 413, thereby improving the cooling effect.

[0041] The cutting module 4 is mounted on the sliding frame 3 via the mounting and positioning module, and the cutting width and angle are adjusted. Specifically, the mounting and positioning module includes a width adjustment component 5 and an angle adjustment component 6. Figure 1 , Figure 2 As shown, the width adjustment assembly 5 includes a third motor 51, a second lead screw 52, ​​and a connecting part 53. The two connecting parts 53 are fixed to the inner side of the side plate 35. The second lead screw 52 spans between the two connecting parts 53. Specifically, the third motor 51 is fixed to the inner side of one of the connecting parts 53, one end of the second lead screw is fixedly connected to the output end of the third motor 51, and the other end is rotatably connected to the connecting part 53 on the opposite side. As an alternative to this embodiment, in other embodiments, the end of the second lead screw 52 can also be rotatably connected to the side plate 35 via a bearing. The second lead screw 52 has two reverse threads for threaded connection to the corners of the two cover plates 41, respectively. When the third motor 51 is turned on, the second lead screw 52 can drive the two cover plates 41 to move towards or away from each other through reversing transmission, thereby changing the cutting width. The transmission method between the second lead screw 52 and the cover plates 41 is not unique.

[0042] like Figure 6As shown, in other embodiments, the width adjustment component 5 has a similar alternative: the second lead screw 52 is disposed between the two cover plates 41, and its length is less than the distance between the two cover plates 41. The third motor 51 is disposed in the middle of the second lead screw 52. Two opposing threads on the surface of the second lead screw 52 are respectively located on both sides of the third motor 51. The two ends of the second lead screw 52 are indirectly connected to the cover plates 41 through an internally threaded rod 54. Specifically, one end of the internally threaded rod 54 is threaded to the second lead screw 52, ​​and the other end is vertically fixed to the inner side of the cover plate 41. In this way, when the second lead screw 52 rotates under the drive of the third motor 51, the two cover plates 41 can move towards each other or away from each other by simultaneously pushing outward or pulling inward on the internally threaded rods 54 at both ends.

[0043] like Figure 1 , Figure 4 As shown, the angle adjustment assembly 6 includes a first connecting rod 61, a second connecting rod 62, a third connecting rod 63, a first connecting shaft 64, a second connecting shaft 65, and a third connecting shaft 66. One end of each of the first connecting rods 61, 62, and 63 is rotatably connected to a single point via the third connecting shaft 66. The other end of the first connecting rod 61 is rotatably connected to the corner of the two cover plates 41 via the first connecting shaft 64. The other end of the second connecting rod 62 is rotatably connected to the side of the U-shaped portion 34 of the sliding frame 3 via the second connecting shaft 65. The other end of the third connecting rod 63 is hinged to the base. If necessary, the third connecting rod 63 can adaptively extend and retract axially. Thus, when the third connecting rod 63 rotates around its hinged end, the angle adjustment assembly 6 adjusts the positioning of the first connecting rod 61 through the transmission relationship between the rods, causing the cover plate 41 to rotate around the second lead screw 52, ​​thereby changing the cutting angle or depth of the saw blade 43. The first connecting shaft 64 is a pluggable telescopic shaft to accommodate changes in the distance between the two cover plates 41. It should be understood that there are various connection methods between the first connecting rod 61, the second connecting rod 62, and the third connecting rod 63. For example, in other embodiments, the third connecting rod 63 may be arranged similarly to the second connecting rod 62, and its hinge end may also be located on the side of the U-shaped portion 34 of the sliding frame 3. As a conventional technique in the field of mechanical equipment, non-substantial modifications to the above-mentioned connecting rod combinations should not depart from the scope of protection of this invention.

[0044] like Figures 1-4As shown, the striking module 7 includes a mounting assembly 71, a power assembly 72, and a pendulum 8. The mounting assembly 71 includes a mounting rod 711, a suspension rod 712, and a mounting shaft 713. Both ends of the mounting rod 711 are fixed to the inner sides of the two cover plates 41, and it is axially extendable. One end of the suspension rod 712 is vertically fixed to the mounting rod 711, and the other end has a clearance opening. The mounting shaft 713 passes through the clearance opening and is rotatably connected to the suspension rod 712. The pendulum 8 includes a swing arm 81 and a striking part 82. One end of the swing arm 81 is fitted with the striking part 82, and the other end is vertically fixed to the mounting shaft 713, allowing it to swing as the mounting shaft 713 rotates. The power assembly 72 includes a push-pull rod 721, a push-pull plate 722, a rack 723, and a gear 724. The push-pull rod 721 employs an electrically operated telescopic structure, with one end fixed to the edge of the cover 41 and the other end vertically fixed to the push-pull plate 722. The push-pull plate 722 also has a rack 723 vertically fixed to the same side. The rack 723 is located inside the cover 41 and meshes with the gears 724 fixed at both ends of the mounting shaft 713 along its length. Necessarily, the extension directions of both the push-pull rod 721 and the rack 723 are perpendicular to the mounting shaft 713. Thus, when the push-pull rod 721 extends or retracts axially, it drives the rack 723 to move axially. The rack 723, through its meshing with the gears 724, further drives the mounting shaft 713 to rotate, thereby causing the pendulum 8 to swing reciprocally, thus striking the mine wall. As an equivalent alternative to this solution, in other embodiments, the gear 724 is fixedly connected to the swing arm 81, and both the gear 724 and the swing arm 81 are rotatably connected to the mounting shaft 713. Based on this connection, the rack 723 can also directly drive the pendulum 8 to swing through meshing and transmission with the gear 724.

[0045] Now combined Figure 7 , Figure 8The structure of the pendulum 8 is further described below. The striking part 82 includes a connecting column 821, a clamping plate 822, and a hammer head 823. The connecting column 821 includes a central column 8211, a first sleeve 8212, and a second sleeve 8215. The central column 8211 includes a sealed end and an open end. The first sleeve 8212 is fitted onto the open end, and the second sleeve 8215 is fitted onto the sealed end. A movable column 8216 is axially inserted through the central column 8211 at the open end. The movable column 8216 has a variable diameter section 8217 near the sealed end, shaped like a vase cross section, the diameter of which first decreases and then increases from the sealed end to the open end. Several elastic positioning pins 8218 are radially inserted through the central column 8211 in the middle. The outer end of the positioning pin 8218 is provided with a ball bearing, and the inner end abuts against the surface of the variable diameter portion 8217 of the movable column 8216 under the action of elastic force. The first sleeve 8212 is a split structure, including a sleeve body 8213 and a plug 8214. The sleeve body 8213 and the plug 8214 are detachably connected axially through a stepped structure. A pin is fixed on the plug 8214, which passes through the end of the sleeve body 8213 and abuts against the movable column 8216. Based on the above structure, when the plug 8214 is fixed to the end of the sleeve body 8213, the pin pushes the movable rod to move towards the side closer to the sealing end. At this time, the variable diameter portion 8217 pushes the positioning pin 8218 outward, exposing the ball bearing to the side surface of the central column 8211. Preferably, a spring can be provided between the movable column 8216 and the sealing end to facilitate the reset of the movable column 8216. As an alternative to this embodiment, in other embodiments, the plug 8214 and the sleeve body 8213 can also be connected by threads.

[0046] The hammerhead 823 has a columnar structure with several rows of protruding teeth distributed on its outer periphery to improve the cell wall breaking effect. Two clamping plates 822 are fixed opposite to each other on the sides of the second sleeve 8215 and the plug 8214. The two ends of the hammerhead 823 are detachably mounted between the two clamping plates 822 via a male-female structure. Specifically, the two clamping plates 822 have relief through holes opposite to each other. A short column 8233 is fixed axially at one end of the hammerhead 823, and a threaded groove 8231 is constructed axially inward at the other end, with a connecting bolt 8232 disposed thereon. When the short column 8233 passes through the relief through hole on one clamping plate 822, the connecting bolt 8232 passes through the relief through hole on the other clamping plate 822 from the outside and is threadedly connected to the threaded groove 8231, thereby mounting the hammerhead 823 onto the clamping plate 822. When it is necessary to replace the hammerhead 823 with a different specification, simply remove the connecting bolt 8232 and pull out the short column 8233, which is convenient and quick. To further improve the installation reliability, in this embodiment, screws are machined on the surface of the short column 8233 and nuts are used to fasten it to the clamping plate 822.

[0047] like Figure 7 As shown, the swing arm 81 has a strip-shaped groove 811 at one end where the striking part 82 is installed. A slidable buffer block 812 and a preload spring 813 are sequentially arranged axially within the strip-shaped groove 811. In relative position, one end of the preload spring 813 is fixed to the buffer block 812, and the other end is fixed to the side of the strip-shaped groove 811 closer to the mounting shaft 713. The preload spring 813 is pre-compressed, pushing the buffer block 812 firmly against the side of the strip-shaped groove 811 away from the mounting shaft 713. The connecting post 821 is perpendicular to the extension direction of the swing arm 81 and is rotatably connected to the buffer block 812. An annular groove is provided within the buffer block 812, and the ball bearing at the outer end of the positioning pin 8218 falls within this annular groove, allowing the connecting post 821 to be axially positioned within the buffer block 812. In the radial direction, a spring-loaded mechanism is installed between the connecting post 821 and the buffer block 812, allowing the striking part 82 to automatically reset after rotation. Thus, when the hammer head 823 strikes the rock wall, the rotating connection between the connecting post 821 and the buffer block 812, and the sliding connection between the buffer block 812 and the swing arm 81, provide double buffering protection for the striking part 82, thereby extending its service life. When the hammer head 823 releases force, the spring-loaded mechanism and the preload spring 813 allow the striking part 82 to instantly reset, demonstrating a reasonable design and ease of use. It is easy to understand that the spring-loaded mechanism is the first elastic reset element described in the claims, and the preload spring 813 is the second elastic reset element described in the claims.

[0048] like Figure 2 , Figure 4 As shown, to facilitate the collection of the cut ore samples, the device is also equipped with a collection module 9. The collection module 9 includes a guide groove 91, a cloth bag, and a collection box 92. The guide groove 91 is slidably installed on the inner side of the two covers 41 and is located below the rack 723. The guide groove 91 can extend beyond the edge of the cover 41 to increase the collection area. A nylon cloth bag is provided between the guide grooves 91 to collect the fallen ore samples and send them into the collection box 92 fixed on the mounting plate 33.

[0049] The above description is merely a preferred embodiment of the present invention and is not intended to limit the patent scope of the present invention. Any technically equivalent modifications made based on the content of this specification shall fall within the protection scope of the present invention.
