Description

Technical Field

[0001] This utility model relates to the field of geological engineering technology, and in particular to a rock and soil breaking device for geological exploration. Background Technology

[0002] A rock and soil breaking device for geological exploration is equipped with a power source, drill bit, hydraulic breaker, and other components. It is specifically designed to break hard rock and soil. During geological exploration, drilling rigs need to go deep underground to obtain samples or construct observation holes. This device uses high-frequency impact to efficiently break such hard structures. By effectively breaking the rock mass, it ensures the acquisition of complete rock core samples at different depths, providing physical support for the analysis of rock strata information.

[0003] The rock and soil breaking device of a geological exploration drilling rig mainly consists of a power drive component, a transmission, a breaking actuator, an adjustment mechanism, and protective components. The power drive component provides power to the device, which is then transmitted to the breaking actuator via the transmission. The breaking actuator directly contacts the rock and soil to complete the breaking operation. The adjustment mechanism can adjust the breaking force and feed speed, while the protective components can prevent debris from flying. All parts work together to ensure that the drilling rig operates efficiently and stably when breaking rock and soil.

[0004] In existing technologies, some rock and soil breaking devices used for geological exploration often use an integrated connection between the cutter head and the main body of the device or multiple sets of complex fasteners for fixation. When a single cutter head is damaged due to wear or breakage, it is necessary to disassemble the entire structure or multiple related components for replacement, making it difficult to achieve individual and rapid disassembly and assembly. This not only prolongs equipment downtime and increases the risk of delays in field exploration operations, but also increases the cost of manpower and time, affecting exploration efficiency.

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

[0035] Reference Figure 1 , Figure 3 and Figure 4 The present invention provides an embodiment of a rock and soil breaking device for geological exploration, comprising a drill bit 1, which is the core component of the device that directly contacts the rock and soil. The drill bit 1 breaks the rock and soil through rotation and the action of the blade 373. The inner and outer walls of the drill bit 1 provide the mounting base for the drill rod 6 and the protective shell 2, respectively. Multiple protective shells 2 are fixedly connected to the outer wall of the drill bit 1. The protective shells 2 are fixed to the outer wall of the drill bit 1 and can block the rock and soil debris that splashes during breaking. At the same time, they provide a closed installation space for the internal quick-release mechanism 3 and protect the components of the quick-release mechanism 3 from damage.

[0036] The protective shell 2 is equipped with a quick-release mechanism 3, which is the core structure for quick disassembly and assembly of the blade 373. Driven by motor 31, the relevant components can be moved quickly to fix and release the blade 373, solving the problem of cumbersome replacement of traditional cutter heads. The drill rod 6 is slidably connected to the inner wall of the drill bit 1. The drill rod 6 is slidably connected to the drill bit 1, providing support and movement guidance for the drill bit 1, allowing the drill bit 1 to move along its axial direction and facilitating adjustment of the crushing position. The outer wall of the drill rod 6 is fixedly connected to a protective shell 4, which is used to protect the internal adjustment component 5 and prevent rock and soil debris and external impurities from entering the adjustment component 5 and affecting its operation. The adjustment component 5 is installed inside the protective shell 4. The adjustment component 5 is used to adjust the height of the drill bit 1. Driven by motor 51, the relevant components are moved to move the drill bit 1 up and down to adapt to the rock and soil crushing requirements at different depths.

[0037] The quick-release mechanism 3 includes a motor 31, which is the power source of the quick-release mechanism 3. It outputs power through forward and reverse rotation to drive the movement of subsequent components to realize the disassembly and assembly of the blade 373. The outer wall of the motor 31 is fixedly connected to the inner wall of the protective shell 2. Fixing the motor 31 inside the protective shell 2 can ensure its stability during operation and avoid positional displacement due to vibration, which would affect the power transmission. The drive end of the motor 31 is fixedly connected to a gear 32. The gear 32 is connected to the drive end of the motor 31 and transmits the rotational motion of the motor 31 to the rack 35. It is a key component for power transmission. The inner wall of the protective shell 2 is fixedly connected to a fixing post 33. The fixing post 33 is fixed to the inner wall of the protective shell 2, and its outer wall provides a sliding track for the clamping plate 34. It guides and limits the movement of the clamping plate 34 and ensures that the clamping plate 34 moves in a straight line.

[0038] A clamping plate 34 is slidably connected to the outer wall of the fixed column 33. The clamping plate 34 slides along the fixed column 33, and by moving, it drives the limiting rod 371 to move closer to or away from the limiting hole 375, thereby fixing and releasing the blade 373. A rack 35 is fixedly connected to the outer wall of the clamping plate 34. The rack 35 meshes with the gear 32. Driven by the gear 32, the clamping plate 34 slides along the fixed column 33, converting the rotational motion of the gear 32 into the linear motion of the clamping plate 34. The outer surfaces of the gear 32 and the rack 35 are meshed. Through the meshing of the gear 32 and the rack 35, power is transferred from electricity... The transmission from motor 31 to clamping plate 34 allows clamping plate 34 to move accordingly based on the rotation direction of motor 31. A limit plate 36 is fixedly connected to the inner wall of the protective shell 2. The limit plate 36 provides a sliding guide for the limit block 374, ensuring that the limit block 374 drives the blade 373 to move along a fixed trajectory, thus ensuring the accuracy of the blade 373's installation position. A limit component 37 is provided on the outer wall of clamping plate 34. The limit component 37 cooperates with clamping plate 34. By engaging or disengaging the limit rod 371 and the limit hole 375, the blade 373 is fixed and released. This is the part that executes the quick-release function.

[0039] Reference Figure 3 and Figure 4 The limiting component 37 includes a limiting rod 371, which is the core actuator of the limiting component 37. By inserting into or disengaging from the limiting hole 375, it directly controls the fixed state of the blade 373. The outer walls of multiple limiting rods 371 are fixedly connected to the outer wall of the clamping plate 34. The limiting rods 371 move synchronously with the clamping plate 34. The movement of the clamping plate 34 directly drives the limiting rods 371 to move closer to or away from the limiting hole 375. Multiple slide rails 372 are fixedly connected to the inner wall of the drill bit 1. The slide rails 372 provide a sliding track for the blade 373, so that the blade 373 can move along a fixed direction during installation and removal, which facilitates precise installation and removal.

[0040] A blade 373 is slidably connected to the outer wall of the slide rail 372. The blade 373 is a component that directly crushes rock and soil. It can be quickly disassembled and assembled by moving along the slide rail 372. It can be replaced in time after wear to ensure crushing efficiency. A limit block 374 is fixedly connected to the outer wall of the blade 373. The limit block 374 moves synchronously with the blade 373. The blade 373 is positioned and fixed by sliding with the limit plate 36 and engaging with the limit rod 371. A limit hole 375 is opened on the inner wall of the limit block 374. The limit hole 375 matches the limit rod 371. When the limit rod 371 is inserted, the limit block 374 is fixed, thereby fixing the blade 373. When the limit rod 371 is disengaged, the blade 373 can be disassembled.

[0041] Reference Figure 1 , Figure 5 and Figure 6 The adjustment component 5 includes a second motor 51, which is the power source of the adjustment component 5. It drives the turntable 52 to move by rotating, providing power for the height adjustment of the drill bit 1. The outer wall of the second motor 51 is fixedly connected to the inner wall of the drill rod 6. Fixing the second motor 51 inside the drill rod 6 can ensure its stability during operation and avoid vibration affecting the adjustment accuracy. The drive end of the second motor 51 is fixedly connected to the turntable 52. The turntable 52 rotates under the drive of the second motor 51, driving the connecting column 53 to make a circular motion. It is a key component for motion conversion. The front side of the turntable 52 is fixedly connected to the connecting column 53. The connecting column 53 makes a circular motion with the turntable 52. Through cooperation with the slide groove 57, the circular motion is converted into the up and down linear motion of the moving frame 56.

[0042] Two fixed plates 54 are fixedly connected to the outer wall of the drill rod 6. The fixed plates 54 provide sliding guides for the connecting plate 1 55, restrict the movement direction of the connecting plate 1 55, and ensure that the moving frame 56 moves stably in a straight line. The inner wall of the fixed plate 54 is slidably connected to the connecting plate 1 55. The connecting plate 1 55 slides along the fixed plate 54 to provide support for the moving frame 56 and ensure that the moving frame 56 does not deviate when moving up and down. The moving frame 56 is fixedly connected to the adjacent side of the two connecting plates 1 55. The moving frame 56 moves up and down under the push of the connecting column 53. The drill bit 1 is driven to rise and fall synchronously through the connecting plate 2 58 to realize the height adjustment of the drill bit 1. The inner wall of the moving frame 56 is provided with a sliding groove 57. The sliding groove 57 provides sliding space for the connecting column 53, so that the circular motion of the connecting column 53 can be converted into the vertical linear motion of the moving frame 56.

[0043] The outer wall of the connecting post 53 contacts the inner wall of the slide groove 57. When the connecting post 53 contacts the inner wall of the slide groove 57, it is an insertion operation. When the connecting post 53 separates from the inner wall of the slide groove 57, it is a release operation. The bottom end of the moving frame 56 is fixedly connected to the connecting plate 2 58. The connecting plate 2 58 is the intermediate component connecting the moving frame 56 and the drill bit 1, transmitting the up-and-down movement of the moving frame 56 to the drill bit 1. The bottom end of the connecting plate 2 58 is fixedly connected to the top end of the drill bit 1. Through the connection of the connecting plate 2 58, the up-and-down movement of the moving frame 56 can directly drive the drill bit 1 to rise and fall, realizing the adjustment of the height of the drill bit 1. The inner wall of the protective shell 1 4 is slidably connected to the protective shell 2 59. The protective shell 2 59 and the protective shell 1 4 cooperate to form a closed space, protecting the adjustment component 5 from external impurities. The protective shell 2 59 can slide up and down with the drill bit 1. The bottom end of the protective shell 2 59 is fixedly connected to the top end of the drill bit 1, protecting the drill bit 1. Shell 2 59 rises and falls synchronously with drill bit 1, ensuring continuous protection of adjustment component 5 during drill bit 1 height adjustment. The outer wall of limit block 374 is slidably connected to the outer wall of limit plate 36. Limit block 374 slides along limit plate 36, ensuring that blade 373 moves along a fixed trajectory during disassembly and assembly, improving installation accuracy. The outer wall of limit rod 371 contacts the inner wall of limit hole 375. When limit rod 371 is inserted into limit hole 375, limit block 374 is fixed, and blade 373 is fixed accordingly; otherwise, blade 373 is released, achieving quick disassembly and assembly. The outer wall of rack 35 is slidably connected to the inner wall of quick-release mechanism 3. Rack 35 slides in quick-release mechanism 3, ensuring stable meshing with gear 32 and ensuring smooth power transmission. The outer wall of drill rod 6 is rotatably connected to prime mover 7. Prime mover 7 provides the main power for the device and transmits power to drill bit 1 through drill rod 6, driving drill bit 1 to rotate to achieve rock and soil breaking operation.

[0044] Working principle: When motor 31 drives gear 32 to rotate clockwise, gear 32 and rack 35 maintain close meshing. This meshing connection accurately transmits the rotational power of motor 31 to rack 35, causing rack 35 to slide smoothly forward along the inner wall of quick-release mechanism 3. Simultaneously, rack 35 drives clamping plate 34 to move forward along the outer wall of fixed post 33. Fixed post 33 provides stable guidance for the sliding of clamping plate 34, preventing it from shifting. As clamping plate 34 moves, it simultaneously drives multiple limiting rods 371 to move forward, causing multiple limiting rods 371 to... 71 gradually disengages from the inner wall of the limiting hole 375. At this point, the fixing effect of the clamping plate 34 on the limiting block 374 is completely released. After the limiting block 374 is no longer restricted, it can slide downward along the outer wall of the limiting plate 36. The limiting plate 36 provides a precise trajectory for the movement of the limiting block 374 to prevent the limiting block 374 from shaking. At the same time, the limiting block 374 drives the blade 373 to move downward synchronously along the outer wall of the slide rail 372. The slide rail 372 guides the blade 373 to maintain linear movement, ensuring a smooth disassembly process. At this point, the disassembly operation of the blade 373 is completed.

[0045] When the blade 373 needs to be installed, the blade 373 is pushed upward along the outer wall of the slide rail 372, while the limiting block 374 moves upward synchronously along the outer wall of the limiting plate 36. The slide rail 372 and the limiting plate 36 together ensure that the installation positions of the blade 373 and the limiting block 374 are accurate. When the limiting block 374 moves to the top of the contact limiting plate 36, the motor 31 drives the gear 32 to rotate counterclockwise. The gear 32 drives the rack 35 to slide backward along the inner wall of the quick release mechanism 3 through meshing with the rack 35. The rack 35 drives the clamping plate 34 to move backward along the outer wall of the fixing post 33. The fixing post 33 continues to provide guidance for the clamping plate 34. The clamping plate 34 simultaneously drives multiple limiting rods 371 to move backward, so that the multiple limiting rods 371 are accurately inserted into the inner wall of the limiting hole 375, forming a firm restriction of the limiting block 374 by the clamping plate 34. At this time, the installation operation of the blade 373 is completed.

[0046] When motor 2 51 drives turntable 52 to rotate, turntable 52 drives connecting column 53 to perform circular motion, and connecting column 53 changes position with the rotation of turntable 52. When connecting column 53 moves from the bottom end of turntable 52 to the top end of turntable 52, the outer wall of connecting column 53 slides along the inner wall of slide groove 57. Guided by the trajectory of slide groove 57, the circular motion is converted into an upward thrust on moving frame 56, causing moving frame 56 to move upward. When moving frame 56 moves, it simultaneously drives connecting plate 1 55 to slide upward along the inner wall of fixed plate 54. Fixed plate 54 provides stable support and guidance for connecting plate 1 55 to prevent moving frame 56 from deviating. Moving frame 56 also drives connecting plate 2 58 to move upward. Connecting plate 2 58 transmits power to drill bit 1, causing drill bit 1 to move upward. At this time, the upward height adjustment of drill bit 1 is completed.

[0047] When the connecting column 53 moves from the top of the turntable 52 to the bottom of the turntable 52, the outer wall of the connecting column 53 continues to slide along the inner wall of the slide groove 57, and the slide groove 57 guides the moving frame 56 to move downward; the moving frame 56 simultaneously drives the connecting plate 1 55 to slide downward along the inner wall of the fixed plate 54, and the fixed plate 54 still provides stable support for the connecting plate 1 55; the moving frame 56 at the same time drives the connecting plate 2 58 to move downward, and the connecting plate 2 58 transmits power to the drill bit 1, driving the drill bit 1 to move downward, at which point the downward height adjustment of the drill bit 1 is completed. Throughout the adjustment process, the connecting plate 55 moves up and down synchronously with the moving frame 56. The opposite sides of the two connecting plates 55 always slide against the inner wall of the fixed plate 54. The connecting plate 55 provides stable support for the up and down movement of the moving frame 56, and together with the fixed plate 54, ensures the smooth movement of the moving frame 56. At the same time, the protective shell 59 moves up and down synchronously with the drill bit 1 and slides along the inner wall of the protective shell 4, forming a closed space with the protective shell 4 to protect the adjustment component 5 from external impurities.

[0048] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
