Description

Technical Field

[0001] This utility model relates to the field of core drilling machines, specifically a splash-proof road surface core drilling machine. Background Art

[0002] Core drilling is a method for testing the properties of pavement materials. It involves drilling core samples from the pavement and conducting laboratory analysis to evaluate the quality and performance of the pavement materials. This method is suitable for assessing pavement conditions, detecting the physical and chemical properties of pavement materials, and determining their durability, adhesion, and deformation performance.

[0003] Patent CN219495716U discloses a road drilling core sampling machine, which includes a core sampling barrel, a base, and a mounting frame fixed to the upper end of the base. The mounting frame is equipped with a drive device for lifting and lowering the core sampling barrel. It also includes two fixed brackets fixed to the upper end of the base. This device, through the cooperation of a striking component, a pushing component, and a connecting component, causes the rubber striking heads on the arc plate to intermittently strike the core sampling barrel, avoiding excessive impact force that could damage the barrel. Simultaneously, it automatically and automatically strikes multiple positions on the outside of the core sampling barrel, ensuring effective material output and facilitating the use of the road drilling core sampling machine. However, this device relies on the core sampling barrel after core extraction... The existing core retrieval machine uses a drive unit to position the core barrel between curved plates. Then, the drive and guide components move the mounting plate, bringing the connecting plates closer together. The curved plates and rubber striking heads then strike the outside of the core barrel to extract the core. However, during the core retrieval process, coolant is often needed to cool the core barrel and reduce dust during drilling. This core retrieval machine lacks a splash-proof mechanism, leading to coolant splashing or dust scattering during drilling, potentially injuring operators. Therefore, a splash-proof road drilling core retrieval machine is proposed to address the problem of coolant splashing affecting operators during core retrieval. Utility Model Content

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] Example: Please refer to Figure 1-6A core drilling machine for splash-proof road surfaces includes a core drilling body 1. A vertical plate 2 is fixedly connected to the top of the core drilling body 1. A drive mechanism 3 is installed inside the vertical plate 2. A drill cylinder 4 is installed on one side of the vertical plate 2. Fixed frames 5 are fixedly connected to both ends of the top of the core drilling body 1. A splash-proof cylinder 6 is installed between the two fixed frames 5. A lifting block 7 and an electric push rod 8 are installed in the inner cavity of the fixed frame 5. A rotating cover 9 is rotatably connected to the top of the splash-proof cylinder 6. Several teeth 10 are installed on the outside of the rotating cover 9. A motor 11 is fixedly connected to one side of the splash-proof cylinder 6. A gear 12 is fixedly connected to the output shaft of the motor 11. A connecting plate 13 is installed at a relative position in the inner cavity of the splash-proof cylinder 6. A collection box 14 is fixedly connected to the bottom of both connecting plates 13. A guide slope shovel head 15 is fixedly connected to the inner cavity of the collection box 14. A sealing cover 16 is snapped onto one side of the collection box 14.

[0025] Furthermore, the drive mechanism 3 includes a moving groove 301 opened on one side of the upright plate 2. The inner cavity of the moving groove 301 is provided with a moving seat 302. The moving groove 301 is rotatably connected to a screw 303, and the moving seat 302 and the screw 303 are threadedly connected.

[0026] Furthermore, a servo motor 304 is fixedly connected to the top of the upright plate 2, and a drilling motor 305 is fixedly connected to the top of the movable seat 302. The output shafts of the servo motor 304 and the drilling motor 305 are fixedly connected to the screw 303 and the drill barrel 4, respectively. After the drill barrel 4 is aligned with the core drilling position, the servo motor 304 is turned on to drive the screw 303 to rotate, which drives the movable seat 302 in the movable slot 301 to move down. This, in conjunction with the drilling motor 305, drives the drill barrel 4 to rotate, thereby drilling and core drilling at the required position.

[0027] Furthermore, the lifting block 7 is slidably connected to the inner cavity of the fixed frame 5 and fixedly connected to the splash guard 6, and the top and bottom of the electric push rod 8 are fixedly connected to the fixed frame 5 and the lifting block 7 respectively.

[0028] Furthermore, the connecting plate 13 is fixedly connected to the rotating cover 9, the gear 12 meshes with the teeth 10, and the two collection boxes 14 are centrally symmetrically distributed with their bottoms flush with the splash guard 6. The electric push rod 8 in the fixing frame 5 drives the lifting block 7 and the splash guard 6 to move down and fit into the road. The mud generated during drilling will hit the wall of the splash guard 6 and then flow to the bottom. In conjunction with the motor 11, gear 12, and teeth 10, the rotating cover 9 and the collection box 14 at the bottom of the connecting plate 13 will rotate. The guide shovel head 15 will shovel the mud into the collection box 14 to avoid mud splashing and achieve the purpose of mud collection.

[0029] Furthermore, a fixing block 17 is fixedly connected to the top and bottom of one side of the upright plate 2, and a stabilizing block 18 is fixedly connected to both ends of the movable seat 302. A sliding rod 19 is fixedly connected between the fixing blocks 17, and the stabilizing block 18 is slidably connected to the outer ring of the sliding rod 19. When the drill barrel 4 is driven to move down by the drive mechanism 3, the stabilizing block 18 between the fixing blocks 17 and the sliding rod 19 are used to improve the stability of the movable seat 302 when it moves up and down, that is, to improve the stability of the drill barrel 4 when it moves down to drill and core.

[0030] Working principle: When using this splash-proof road drilling and coring machine, the main body 1 is used to move the coring machine to the required position. Then, the drive mechanism 3 drives the drill cylinder 4 to move down for drilling and coring. During the process, the electric push rod 8 in the fixed frame 5 drives the lifting block 7 and the splash-proof cylinder 6 to move down and contact the road. Then, when the coolant is used to cool the rotating drill cylinder 4, the mud will hit the wall of the splash-proof cylinder 6 and flow to the bottom. In conjunction with the motor 11 driving the gear 12, the teeth 10 on the rotating cover 9 drive the collection box 14 at the bottom of the connecting plate 13 to rotate. With the help of the guide shovel head 15, the mud is shoveled into the collection box 14, avoiding mud slurry. The splashing action achieves the purpose of mud collection, solving the problem of coolant splashing during the core sampling process of existing core sampling machines, which affects the operators. After the drill barrel 4 is aligned with the core sampling position, the servo motor 304 is turned on to drive the screw 303 to rotate, which drives the moving seat 302 in the moving slot 301 to move down. In conjunction with the drilling motor 305, the drill barrel 4 is rotated, and then the core is drilled at the required position. After completion, the drill barrel 4 is moved out of the splash guard 6, and then the rotating cover 9 is moved up to remove it from the top of the splash guard 6. Then, in conjunction with the connecting plate 13, the collection box 14 is removed from the top of the splash guard 6. The snap-fit ​​sealing cover 16 is removed to facilitate the removal of mud mixed with coolant.
