[0020] Example 1 See Figures 1 to 4 This utility model provides a rebar hole cleaning device that integrates blowing and brushing, including a power output device 1 and a blowing and brushing assembly 2 detachably connected to the power output device 1; the power output device 1 is used to provide power to the blowing and brushing assembly 2, and the power output device 1 is a device with a rotation power output function, which can be a hand drill, motor, pneumatic rotary tool, etc., connected to the blowing and brushing assembly 2, and transmits the rotation power to the blowing and brushing assembly 2 to provide continuous power for the cleaning operation of the rebar hole; The brush blowing assembly 2 includes a housing 3, a gear frame 4 is rotatably arranged inside the housing 3, and a clamping part 5 is fixedly arranged in the middle of one side of the gear frame 4. The power output device 1 is detachably connected to the clamping part 5. A blowpipe 6 is fixedly installed in the middle of the other side of the gear frame 4. The blowpipe 6 is a hollow tube, one end of which is fixedly connected to the gear frame 4, and the other end is provided with a blowhead 7. Several air outlets 8 are provided on the blowhead 7. The outer surface of the blowpipe 6 is provided with bristles 9 arranged in a spiral pattern.

[0021] First, based on the cleaning requirements of the anchor holes, select a suitable power output device 1, such as an electric drill, motor, or pneumatic rotary tool, and detachably connect it to the clamping part 5 of the brush assembly 2 to ensure a stable connection. Subsequently, holding the power output device 1, insert the end of the brush assembly 2 with the blow head 7 and brush bristles 9 into the anchor hole, start the power output device 1, and the rotational power generated is transmitted to the gear frame 4 through the clamping part 5, which drives the gear frame 4 to rotate inside the housing 3, thereby causing the blow pipe 6 connected to the gear frame 4 to rotate synchronously. When the blowpipe 6 rotates, the bristles 9 arranged in a spiral pattern on the outer surface will brush the inner wall of the anchor hole, loosening and sweeping up the dust, debris and other impurities in the hole. At the same time, gas can be introduced into the pipe through the hollow structure of the blowpipe 6. The gas is sprayed out through several air outlets 8 on the blowpipe 7, blowing the impurities swept up by the bristles 9 out of the anchor hole. During the cleaning process, the rotation speed of the power output device 1 can be adjusted according to the actual situation. After cleaning is completed, the power output device 1 is turned off, the brush assembly 2 is removed from the anchor hole, and then the power output device 1 and the brush assembly 2 are separated.

[0022] The inner wall of the outer casing 3 is provided with teeth, and the output gear 10 is rotatably arranged in the middle of the outer casing 3. Several intermediate gears 11 are rotatably arranged on the frame of the gear carrier 4, and the intermediate gears 11 mesh with the output gear 10 and the outer casing 3 respectively.

[0023] The output gear 10 is ring-shaped, and a fan blade 12 is fixedly installed on its inner wall.

[0024] When the power output device 1 is started, the power is transmitted to the gear carrier 4, causing the gear carrier 4 to start rotating as the driving component. When the gear carrier 4 rotates, it drives the intermediate gear 11 on it to revolve together with the gear carrier 4. At the same time, because the intermediate gear 11 meshes with the teeth on the inner wall of the outer casing 3, the outer casing 3 remains stationary. The intermediate gear 11 rotates on its own axis during the revolution. Since the intermediate gear 11 also meshes with the output gear 10, the rotation of the intermediate gear 11 drives the output gear 10 to rotate, and the output gear 10 achieves accelerated rotation. When the output gear 10 rotates at an increased speed, the fan blades 12 fixed on its inner wall rotate synchronously at high speed. The rotation of the fan blades 12 generates airflow, which is ejected from the air outlet 8 of the blower head 7 through the internal channel of the blowpipe 6. At the same time, the rotation of the gear frame 4 drives the blowpipe 6 and the brush 9 to rotate. The brush 9 brushes and cleans the inner wall of the rebar hole. The ejected airflow discharges the impurities cleaned by the brush 9 from the rebar hole. After cleaning the hole, the power output device 1 is turned off, and the connection between the power output device 1 and the clamping part 5 is disconnected.

[0025] The gear transmission structure adopts a gear frame 4 as the driving gear and a housing 3 as the fixed gear. The intermediate gear 11 meshes with the housing 3 and the output gear 10 respectively to realize the speed-increasing transmission of the output gear 10. This can effectively improve the rotational speed of the output gear 10 and the fan blade 12, enhance the airflow intensity and velocity, improve the ability to blow away impurities in the anchor hole, and make the hole cleaning more thorough.

[0026] The inner wall of the ring output gear 10 is provided with fan blades 12. The fan blades 12 are directly driven by the speed-increasing rotation of the output gear 10, which eliminates the need for an additional power source, simplifies the equipment structure, reduces energy consumption, and ensures that the fan blades 12 are synchronized with the brushing action, thereby ensuring the coordination between the cleaning of the brush bristles 9 and the airflow blowing, and improving the cleaning efficiency.

[0027] The overall gear transmission structure is compact, occupies little space, and has high transmission efficiency. It can effectively convert the energy of the power output device 1 into the high-speed rotation of the fan blade 12 and the rotational power of the brush bristles 9, thereby improving the energy utilization rate of the equipment.

[0028] The air outlet 8 is set at an angle, and a circumferential array is arranged on the blower head 7.

[0029] The air outlet 8 is set at an angle, which allows the airflow to act on the inner wall of the anchor hole or the space inside the hole at an angle, forming an oblique impact force, which makes it easier to blow away stubborn impurities attached to the hole wall.

[0030] A handle 13 is fixedly installed on the outer wall of the outer casing 3.

[0031] A handle 13 is fixedly installed on the outer wall of the outer casing 3, providing the operator with a stable grip, which facilitates precise control of the insertion angle, depth and movement trajectory of the equipment during the hole cleaning operation, and effectively avoids equipment shaking caused by unstable hand grip.

[0032] When using this utility model, the clamping part of the power output device 1 and the brush assembly 2 are detachably connected. The operator holds the handle 13 on the outer wall of the outer shell 3 and starts the power output device 1. Its rotational power is transmitted to the gear frame 4, which drives the blowpipe 6 and the outer spiral bristles 9 to rotate and brush the inner wall of the anchor hole. At the same time, the gear 4 drives the fan blade 12 to rotate at high speed to generate airflow, which is sprayed out from the air outlet 8 of the blowpipe 7 through the blowpipe 6. Loose impurities on the bristles 9 are promptly blown out by the airflow. During the process, the insertion depth of the equipment and the power output speed can be adjusted. After cleaning the hole, turn off the power output setting 1 and disassemble its connection with the clamping part 5.

[0033] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
