Description
Technical Field
[0001] The utility model relates to the field of core drills, in particular to a core drill for preventing mud splashing. Background Art
[0002] Concrete core drills are mainly used for core sampling of cement concrete, asphalt concrete, and limestone foundations such as highways, airports, ports, docks, and dams for compressive and flexural tests. The concrete core drill can be used for multiple purposes (optional), such as drilling for core sampling, core sample cutting, and core sample grinding, which greatly improves work efficiency and reduces equipment investment. It is an ideal engineering detection device.
[0003] When a traditional highway core drill is performing core sampling operations, it drills holes in the road surface through a drill.

[0014] By adopting the above technical solution, the two synchronous wheels in the synchronous wheel group can be rotated synchronously through the synchronous belt, thereby driving the drill bit to rotate and take cores.
[0015] Furthermore, an adjusting screw rod is threadedly connected to the middle part of the fixing seat, a rotating handle is fixed to the top end of the adjusting screw rod, and the bottom of the adjusting screw rod is connected to the frame bearing.

[0034] As Figures 1 - 3 shown, a core drill for preventing mud splashing in this embodiment includes a frame 1, a transmission mechanism 2 for driving is arranged on the frame 1, a drill bit 3 is fixedly installed below one side of the transmission mechanism 2, the drill bit 3 can be used for core sampling, and a protection mechanism 4 is installed on one side of the bottom of the frame 1, the protection mechanism 4 is located below the drill bit 3, and the axis of the protection mechanism 4 corresponds to the axis of the drill bit 3.
[0035] Among them, the protection mechanism 4 includes a casing 401 fixed to the frame 1. The casing 401 can block mud and dust. Inside the casing 401, multiple groups of cutter holders 402 are installed vertically around. In the middle of the casing 401, a connecting disk 403 is rotatably installed. During the rotation of the connecting disk 403 under force, it can drive multiple groups of cutting frames 405 to rotate synchronously. Inside the connecting disk 403, multiple groups of protective covers 404 are evenly installed around. The protective covers 404 can seal the contact points between the connecting disk 403 and the drill bit 3. And the protective covers 404 are hinged to the connecting disk 403, and the rotation angle of the protective covers 404 is 180 degrees. Through the rotation of the protective covers 404, the use requirements of drill bits 3 with different diameters can be met. At the bottom of the connecting disk 403, multiple groups of cutting frames 405 are evenly installed, and the cutting frames 405 and the cutter holders 402 are offset from each other. Through the coordinated use of the cutting frames 405 and the cutter holders 402, the impurities generated during the coring process can be effectively broken.
[0036] As Figure 1 and Figure 6 As shown, on both sides inside the frame 1, two groups of guide rods 7 are symmetrically installed. The guide rods 7 can guide the fixed seat 6. The fixed seat 6 is slidably connected to the guide rods 7. The fixed seat 6 can drive the transmission mechanism 2 and the drill bit 3 to lift and lower synchronously. On one side of the fixed seat 6 facing the drill bit 3, a connecting seat 5 is installed. And at the bottom of the connecting seat 5, a drive shaft for installing the drill bit 3 is rotatably connected. On the side of the fixed seat 6 opposite to the connecting seat 5, it is fixedly connected to the transmission mechanism 2, which is convenient for the transmission mechanism 2 to drive the drive shaft on the connecting seat 5 to rotate, thereby driving the drill bit 3 to rotate.
[0037] As Figures 5 - 6 As shown, the transmission mechanism 2 includes a motor 201 installed on the fixed seat 6. The motor 201 can drive the synchronous pulley set 202 to rotate. The output end of the motor 201 is fixed with the synchronous pulley set 202. The synchronous pulley set 202 includes two synchronous pulleys at the same horizontal height. Tooth grooves are formed on the synchronous pulleys. And on the outside of the two synchronous pulleys, a synchronous belt 203 is meshed and connected through the tooth grooves. The synchronous belt 203 can drive the two synchronous pulleys to rotate simultaneously. One of the synchronous pulleys is fixedly connected to the drive shaft at the bottom of the connecting seat 5.
[0038] As Figure 1 and Figure 6 As shown, in the middle of the fixed seat 6, an adjusting screw rod 8 is connected by threads. The top of the adjusting screw rod 8 is fixed with a handle 9. The staff can use the handle 9 to drive the adjusting screw rod 8 to rotate. The bottom of the adjusting screw rod 8 is connected to the frame 1 through a bearing. At the bottom of the frame 1, three moving wheels 10 are evenly fixed, which is convenient for the core drill to move through the moving wheels 10.

[0039] The specific implementation process of this embodiment is as follows: The staff pushes the frame 1, so that the core drill moves to the core-taking position through the moving wheels 10 on the frame 1. The staff uses the rotary handle 9 to drive the adjusting screw rod 8 to rotate, and then makes the fixed seat 6 move downward along the guide rod 7, which can drive the drill bit 3 to move downward. When the drill bit 3 moves into the protection mechanism 4, the drill bit 3 drives a plurality of protection covers 404 to rotate synchronously. The protection covers 404 are turned over and rotated under force, which can meet the use requirements of drill bits 3 with different diameters. After the bottom end of the drill bit 3 enters the machine shell 401, the motor 201 in the transmission mechanism 2 drives the synchronous pulley set 202 and the synchronous belt 203 to work, and then the drive shaft on the connecting seat 5 drives the drill bit 3 to rotate. During the rotation of the drill bit 3, the staff continues to rotate the adjusting screw rod 8 to make the drill bit 3 enter the ground for core-taking;
[0040] During the core-taking process, the machine shell 401 in the protection mechanism 4 is located outside the drill bit 3, which can effectively prevent mud and dust from splashing into the working environment. The protection brush 12 is fixed on the outside of the machine shell 401 through the mounting seat 11. The protection brush 12 can secondly block the mud and dust, improve the quality of the operation environment, and ensure the health of the staff. At the same time, the protection cover 404 abuts against the drill bit 3, which can drive the connecting disc 403 to rotate along the machine shell 401 during the core-taking process. The connecting disc 403 can drive a plurality of cutting frames 405 to rotate synchronously. The synchronous rotation of the plurality of cutting frames 405 cooperates with the cutter rest 402 to crush the larger impurities generated during the core-taking process, avoiding the damage of the drill bit 3 caused by the impact of these impurities during the core-taking process.
