DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0035] In the description of the present invention, it should be noted that the terms "upper", "lower", "inner", "outer", "top / bottom" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific position, be constructed and operated in a specific position, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0036] In the description of the present invention, it should be noted that, unless otherwise clearly stipulated and limited, the terms "installed", "provided with", "installed / connected", "connected", etc. should be understood in a broad sense. 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 the internal connection of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0037] like Figures 1 to 8 As shown, an embodiment of the present invention provides a geological sampling device for mine tunnels (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 knocking module 7 and a collecting module 9. In general, the pushing module 2 is fixed on the base plate 1, driving the sliding frame 3 to slide along the length direction of the base plate 1. The cutting module 4 and the knocking module 7 are movably mounted on the sliding frame 3 to cut and knock the rocks. 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 collecting module 9 is used to collect the rock samples that are shot down. The specific structure and connection relationship of the above-mentioned components are described in detail below in conjunction with the drawings.

[0038] like Figure 1 to Figure 4As shown, the bottom plate 1 is rectangular, and a plurality of slide rails 11 are arranged in parallel on the top of the bottom plate 1 along the length direction. The push module 2 includes a first end plate 21, a first motor 22 and a first screw rod 23. The first screw rod 23 is the transmission rod described in the claims. The first end plate 21 is vertically fixed to the top of the bottom 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 is connected to the first screw rod 23 at the output end. The extension direction of the first screw rod 23 is parallel to the slide rail 11. The sliding frame 3 is provided with a plurality of support columns 31 and a limit block at the bottom. The support column 31 is located in the slide rail 11 to support the sliding frame 3. The limit block is sleeved in the extension direction of the first screw rod 23 and is threadedly matched with the first screw rod 23. In this way, when the first motor 22 is turned on, the sliding frame 3 can be driven to slide back and forth along the extension direction of the slide rail 11 through the reversing transmission of the first screw rod 23 and the limit portion 32. Furthermore, in order to improve stability, the push module 2 also includes a plurality of 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 to 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 limit portion 32 to guide the slide frame 3. It is not difficult to understand that in other embodiments, the above-mentioned limit portion 32 can also be the support column 31. In a further functional upper position, as an equivalent replacement of this embodiment, in other embodiments, the combination of the first motor 22 and the first screw rod 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 limit portion 32, and drives the slide frame 3 to slide along the extension direction of the slide rail 11 through axial expansion and contraction.

[0039] The sliding frame 3 further 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 passes through the second end plate 341 of the U-shaped portion 34 and is radially limited with the latter. The two side plates 35 are arranged opposite to each other along the width direction of the bottom plate 1, that is, perpendicular to the direction of the track.

[0040] The cutting module 4 includes a housing 41, a second motor 42 and a saw blade 43. The two housings 41 are arranged opposite to each other along the width direction of the bottom plate 1, that is, the housings 41 are parallel to the side plates 35. The two second motors 42 are respectively fixed vertically on the outside of the housing 41, and their output ends extend into the housing 41 and are fixedly connected to the saw blade 43 in the housing 41. Preferably, as Figure 5As shown, the cover shell 41 is internally constructed with a relatively closed cavity 412 through a sealing plate 411, and the cavity 412 is filled with a coolant 413 to cool the saw blade 43. The cover shell 41 is provided with a U-shaped dust suction duct 414 at the outer edge of the cavity 412, and the dust suction duct 414 is connected to an external vacuum cleaner through a connecting pipe 415 to purify the air during sampling. A metal filter is provided at the opening of the dust suction duct 414 to prevent large particles of stone from entering. A plurality of heat dissipation fins 416 are provided between the cavity 412 and the dust suction duct 414, and the heat of the coolant 413 is taken away by the gas flow in the dust suction duct 414, thereby improving the cooling effect.

[0041] The cutting module 4 is installed on the sliding frame 3 through the installation and positioning module, and adjusts the cutting width and angle. Specifically, the installation 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 screw rod 52 and a connecting portion 53. The two connecting portions 53 are relatively fixed on the inner side of the side plate 35. The second screw rod 52 is arranged between the two connecting portions 53. Specifically, the third motor 51 is fixed on the inner side of one of the connecting portions 53, one end of the second screw rod is fixedly connected to the output end of the third motor 51, and the other end is rotatably connected to the connecting portion 53 on the opposite side. As an alternative to this embodiment, in other embodiments, the end of the second screw rod 52 can also be rotatably connected to the side plate 35 through a bearing. The second screw rod 52 is provided with two sections of reverse threads to be threadedly connected to the corners of the two cover shells 41 respectively. When the third motor 51 is turned on, the second screw rod 52 can drive the latter to move toward or away from each other through the reversing transmission with the two cover shells 41 to change the cutting width. The transmission method between the second screw rod 52 and the cover shell 41 is not unique.

[0042] like Figure 6As shown, in other embodiments, there is a similar alternative for the width adjustment component 5: the second screw rod 52 is arranged between the two cover shells 41, and its length is less than the spacing between the two cover shells 41. The third motor 51 is arranged in the middle of the second screw rod 52. The two opposite threads on the surface of the second screw rod 52 are respectively located on both sides of the third motor 51. The two ends of the second screw rod 52 are indirectly connected to the cover shell 41 through an internal threaded rod 54, specifically, one end of the internal threaded rod 54 is threadedly connected to the second screw rod 52, and the other end is vertically fixed to the inner side of the cover shell 41. In this way, when the second screw rod 52 rotates under the drive of the third motor 51, the two cover shells 41 can be moved toward or away from each other by simultaneously pushing or pulling the internal threaded rod 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 ends of the first connecting rod 61, the second connecting rod 62 and the third connecting rod 63 are connected to a point through the third connecting shaft 66. The other end of the first connecting rod 61 is connected to the corner of the two-piece cover 41 through the first connecting shaft 64. The other end of the second connecting rod 62 is connected to the side of the U-shaped portion 34 of the sliding frame 3 through the second connecting shaft 65. The other end of the third connecting rod 63 is hinged to the base. Necessarily, the third connecting rod 63 can be adaptively telescopic in the axial direction. In this way, when the third connecting rod 63 rotates around the hinged end, the angle adjustment assembly 6 adjusts the positioning of the first connecting rod 61 through the transmission relationship between the rods, drives the cover 41 to rotate around the second screw rod 52, and thus changes the cutting angle or depth of the saw blade 43. The first connecting shaft 64 is a plug-in telescopic shaft to adapt to the change of the distance between the two cover shells 41. It should be understood that there are multiple ways to connect 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 can be arranged in a similar manner to the second connecting rod 62, and its hinged end can also be arranged on the side of the U-shaped portion 34 of the sliding frame 3. As a conventional technology in the field of mechanical equipment, non-substantial changes to the above-mentioned connecting rod connection combination should not deviate from the protection scope of the present invention.

[0044] like Figure 1 to Figure 4As shown, the knocking 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. The two ends of the mounting rod 711 are respectively fixed to the inner side of the two-piece cover shell 41 and can be retracted and extended along the axial direction. One end of the suspension rod 712 is vertically fixed to the mounting rod 711, and the other end is provided with a clearance opening. The mounting shaft 713 is penetrated in the clearance opening and is rotatably connected with the suspension rod 712. The pendulum 8 includes a swing arm 81 and a knocking part 82. The knocking part 82 is installed at one end of the swing arm 81, and the other end is vertically fixed to the mounting shaft 713 to swing with the rotation of the mounting shaft 713. 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 adopts an electric telescopic structure, one end of which is fixed to the edge of the housing 41, and the other end is vertically fixed to the push-pull plate 722. The push-pull plate 722 is also vertically fixed to the rack 723 on the same side. The rack 723 is arranged on the inner side of the housing 41 and is meshed with the gear 724 fixed at both ends of the mounting shaft 713 along the length direction. It is necessary that the extension direction of the push-pull rod 721 and the rack 723 are both perpendicular to the mounting shaft 713. In this way, when the push-pull rod 721 is axially extended and retracted, the rack 723 is driven to move axially, and the rack 723 further drives the mounting shaft 713 to rotate through the meshing transmission with the gear 724, thereby causing the pendulum 8 to swing back and forth to achieve the knocking of the mine rock wall. As an equivalent alternative to the present scheme, in other embodiments, the gear 724 is fixedly connected to the swing arm 81, and the gear 724 and the swing arm 81 are both rotatably connected to the mounting shaft 713. Based on this connection relationship, the rack 723 can also directly drive the pendulum 8 to swing by meshing with the gear 724.

[0045] Now combined Figure 7 , Figure 8, the structure of the pendulum 8 is further described. The striking part 82 includes a connecting column 821, a splint 822 and a hammer head 823. The connecting column 821 includes a middle column 8211, a first sleeve 8212 and a second sleeve 8215. The middle column 8211 includes a sealed end and an open end. The first sleeve 8212 is sleeved on the open end, and the second sleeve 8215 is sleeved on the sealed end. The middle column 8211 is axially penetrated by a movable column 8216 at the open end. The movable column 8216 is provided with a reducing portion 8217 at a position close to the sealed end, which is shaped like a vase cross-section, and the diameter of the reducing portion 8217 first decreases and then increases from the sealed end to the open end. The middle column 8211 is radially penetrated by a plurality of elastic positioning pins 8218 in the middle. The outer end of the positioning pin 8218 is provided with a ball, and the inner end abuts against the surface of the reducing 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 along the axial direction through a stepped structure. A plug is fixed on the plug 8214, and the plug 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 plug pushes the movable rod to move toward the side close to the sealing end, and at this time, the reducing portion 8217 pushes the positioning pin 8218 outward, so that the ball is exposed to the side surface of the middle column 8211. Preferably, a spring may be provided between the movable column 8216 and the sealing end to facilitate the resetting of the movable column 8216. As an alternative to this embodiment, in other embodiments, the plug 8214 and the sleeve body 8213 may also be connected by a thread.

[0046] The hammer head 823 is a columnar structure, and the hammer head 823 is provided with several rows of convex teeth on the periphery to improve the wall breaking effect. Two plywoods 822 are fixed relatively to the sides of the second sleeve 8215 and the plug 8214, and the two ends of the hammer head 823 are detachably mounted between the two plywoods 822 through a male-female structure. Specifically, the two plywoods 822 are provided with through holes for making way relatively. A short column 8233 is fixed axially at one end of the hammer head 823, and a threaded groove 8231 is constructed axially inwardly at the other end and is provided with a connecting bolt 8232. When the short column 8233 is inserted into the through hole for making way on the plywood 822 on one side, the connecting bolt 8232 passes through the through hole for making way on the plywood 822 on the other side from the outside, and is threadedly connected with the threaded groove 8231, so that the hammer head 823 is mounted on the plywood 822. When it is necessary to replace the hammer head 823 of different specifications, it is only necessary to 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 fastened to the clamping plate 822 with nuts.

[0047] like Figure 7 As shown, the swing arm 81 is constructed with a strip-shaped through groove 811 at one end where the knocking part 82 is installed. A slidable buffer block 812 and a preload spring 813 are sequentially arranged in the strip-shaped through groove 811 along the axial direction. In relative position, one end of the preload spring 813 is fixed on the buffer block 812, and the other end is fixed on the side of the strip-shaped through groove 811 closer to the mounting shaft 713. The preload spring 813 is pre-stressed to push the buffer block 812 firmly against the side of the strip-shaped through groove 811 away from the mounting shaft 713. The connecting column 821 is perpendicular to the extending direction of the swing arm 81 and is rotatably connected to the buffer block 812. An annular groove is arranged in the buffer block 812, and the ball at the outer end of the positioning pin 8218 falls into the annular groove, so that the connecting column 821 is limitedly matched with the buffer block 812 along the axial direction. In the radial direction, a clockwork spring is installed between the connecting column 821 and the buffer block 812, so that the knocking part 82 can automatically reset after rotating. In this way, when the hammer head 823 knocks the rock wall, the knocking part 82 is double-buffered and protected by the rotational connection between the connecting column 821 and the buffer block 812, and the sliding connection between the buffer block 812 and the swing arm 81, thereby extending the service life. When the hammer head 823 unloads force, the clockwork spring and the pre-tightening spring 813 allow the knocking part 82 to reset instantly, which is reasonable in design and easy to use. It is not difficult to understand that the clockwork spring is the first elastic reset member described in the claims, and the pre-tightening spring 813 is the second elastic reset member described in the claims.

[0048] like Figure 2 , Figure 4 As shown, in order to facilitate the collection of the cut ore samples, the device is also provided 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 mounted on the inner side of the two cover shells 41 and is located below the rack 723. The guide groove 91 can extend out of the edge of the cover shell 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.
