Description

Technical Field

[0001] This application relates to the field of engine carbon deposit cleaning equipment, and in particular to a walnut shell cleaning machine. Background Technology

[0002] Currently, walnut shell carbon cleaning machines are devices used to clean carbon deposits in engines. When in use, compressed air sends walnut shells into the engine, where the high-speed movement of the walnut shells impacts the carbon deposits, thus removing them.

[0003] The relevant technology can be found in Chinese Patent No. CN212824793U, which discloses a walnut shell carbon deposit cleaning machine. The machine includes a cleaning body with a sandblasting pipe on its outer wall. A spray gun is located at the end of the sandblasting pipe, and both ends of the sandblasting pipe are connected to the spray gun and the interior of the cleaning body, respectively. A suction pipe is also located on the outer wall of the cleaning body, with a recovery connector at its end. Through a rotating mechanism, the nozzle of the spray gun passes through an insertion hole on a sphere. When cleaning engine carbon deposits, the user slightly rotates the nozzle, causing the sphere to rotate within a rotating groove. This changes the traditional method of the nozzle rotating directly on the recovery connector, preventing wear and tear on the recovery connector that could expose walnut shells and ensuring operational safety.

[0004] Regarding the aforementioned technologies, spray guns typically only clean the area directly opposite the engine. For carbon deposits in other directions inside the engine, workers need to manually rotate the spray gun. However, this manual rotation method is not only limited in angle, making it difficult to achieve multi-directional and multi-angle cleaning, but also causes the suction pipe to rotate simultaneously during the spray gun rotation. This results in the suction pipe not being able to completely block the engine, allowing some of the cleaned carbon deposits and walnut shells to flow out through the gaps. Summary of the Invention

[0005] To improve the cleaning effect, this application provides a walnut shell cleaning machine.

[0006] This application provides a walnut shell washing machine, which adopts the following technical solution: A walnut shell cleaning machine includes a machine body and a spray gun. The machine body is connected to a suction pipe and a spraying pipe. The spray gun includes an air inlet, a connecting pipe, a nozzle, a first drive device, and a second drive device. The end of the spraying pipe away from the machine body is connected to the nozzle. The connecting pipe is rotatably connected to the air inlet along its own axis. A baffle is fixed on the outer wall of the end of the suction pipe away from the machine body. The connecting pipe is located inside the suction pipe and the two are coaxially arranged. The connecting pipe is rotatably connected to the nozzle. The rotation axis of the nozzle is perpendicular to the rotation axis of the connecting pipe. The first drive device is used to drive the mutual rotation between the connecting pipe and the air inlet, and the second drive device is used to drive the mutual rotation between the nozzle and the connecting pipe.

[0007] By adopting the above technical solution, the connecting pipe of the spray gun can rotate along its own axis and the air intake end, and the nozzle is rotatably connected to the connecting pipe with the rotation axes perpendicular to each other. Combined with the first drive device driving the connecting pipe to rotate relative to the air intake end, and the second drive device driving the nozzle to rotate relative to the connecting pipe, the nozzle end can achieve multi-directional and multi-angle rotation and oscillation. Thus, when using the walnut shell cleaning machine to clean the inside of the engine, the nozzle end can flexibly adjust its position and angle, accurately spraying walnut shells onto various parts inside the engine, thereby cleaning carbon deposits inside the engine from multiple directions and angles, improving cleaning effect and efficiency.

[0008] Optionally, the air inlet is fixedly connected to the sand suction pipe. The first driving device includes a first motor, a first worm and a first worm wheel. A first dustproof box is fitted on the outer side of the first worm and the first worm wheel. The first dustproof box is fixedly connected to the inner wall of the sand suction pipe. The baffle is fixedly connected to the first motor. The output end of the first motor is fixedly connected to the first worm coaxially. The connecting pipe is fixedly connected to the first worm coaxially. The first worm and the first worm wheel mesh with each other.

[0009] By adopting the above technical solution, the air intake end is fixedly connected to the sand suction pipe, ensuring the stability of the air intake end. The output end of the first motor is fixedly connected coaxially to the first worm gear, and the connecting pipe is fixedly connected coaxially to the first worm wheel. The first worm gear and the first worm wheel mesh with each other, realizing mutual rotation between the connecting pipe and the air intake end. At the same time, the first dustproof box, which is jointly fitted on the outer side of the first worm gear and the first worm wheel, is fixedly connected to the inner wall of the sand suction pipe, which can prevent dust and other impurities from entering the transmission structure of the first worm gear and the first worm wheel, reducing wear and extending their service life. The baffle is fixedly connected to the first motor, providing a stable mounting base for the first motor, enabling the first drive device to operate more stably, and thus allowing the connecting pipe of the spray gun to rotate flexibly, which helps to achieve multi-directional and multi-angle cleaning of carbon deposits inside the engine.

[0010] Optionally, a first cylinder is fixedly connected to one end of the connecting pipe near the nozzle, and a second cylinder is fixedly connected to one end of the nozzle near the connecting pipe, with the first cylinder and the second cylinder being rotatably connected coaxially.

[0011] By adopting the above technical solution, the nozzle end can rotate flexibly relative to the connecting pipe, thereby expanding the spray range and angle of the nozzle end. This helps to clean carbon deposits in different positions and angles inside the engine from multiple directions and angles, improving the cleaning effect of the walnut shell cleaning machine on engine carbon deposits.

[0012] Optionally, the second driving device includes a second motor, a second worm gear, and a second worm wheel. A second dustproof box is fitted around the outer sides of the second worm gear and the second worm wheel. The second dustproof box is fixedly connected to the first cylinder. The second worm gear is coaxially fixed to the outer wall of the second cylinder. The second worm gear meshes with the second worm wheel. The baffle includes an inner circular plate and an outer plate. The inner circular plate and the outer plate are rotatably connected. One end of the second worm gear passes through the baffle and is rotatably connected to the inner circular plate along its own axis. The second motor is fixedly connected to the inner circular plate and is used to drive the second worm gear to rotate.

[0013] By adopting the above technical solution, the second motor of the second drive device drives the second worm to rotate. Since the second worm meshes with the second worm wheel and is coaxially fixed to the outer wall of the second cylinder, the nozzle end can rotate relative to the connecting pipe. The second dustproof box, sleeved on the outside of the second worm and the second worm wheel, is fixedly connected to the first cylinder, preventing dust and other impurities from entering and affecting the transmission. The inner circular plate of the baffle is rotatably connected to the outer plate. One end of the second worm passes through the baffle and is rotatably connected to the inner circular plate along its own axis. The second motor is fixedly connected to the inner circular plate, ensuring the stability of the second drive device structure and the reliability of the transmission. This allows the nozzle end to rotate flexibly, thereby enabling multi-directional and multi-angle cleaning of carbon deposits inside the engine.

[0014] Optionally, a camera is fixedly mounted on the outer side of the nozzle end, the cleaning machine body is equipped with a display screen, the camera is connected to the display screen via a wireless signal, and the lens end of the camera is equipped with a light source.

[0015] By adopting the above technical solution, a camera is installed on the outside of the nozzle and connected to the display screen of the cleaning machine body via wireless signal. The image of the nozzle location can be transmitted to the display screen in real time. The operator can clearly observe the internal condition of the engine through the display screen, providing accurate position guidance for the spraying and cleaning of walnut shells, which is conducive to more precise cleaning of carbon deposits inside the engine. The light source set at the camera lens can provide illumination in the relatively dark environment inside the engine, enhance the clarity of the camera image, and further improve the accuracy of the operator's observation of the internal condition of the engine, thereby achieving a better cleaning effect on the carbon deposits inside the engine.

[0016] Optionally, a power source is fixedly provided on the outer wall of the nozzle end, and a scraper is fixedly connected to the rotating shaft of the power source. Several bristles are fixedly provided on the side of the scraper near the lens end of the camera, and the scraper is used to block the camera.

[0017] By adopting the above technical solution, during the use of the walnut shell cleaning machine, the power source can drive the scraper to rotate. When the scraper rotates, the bristles on it can clean the camera lens, preventing impurities such as walnut shells from adhering to the camera lens and affecting the shooting effect. When the scraper is not cleaning, it can shield the camera, which can protect the camera lens and prevent the lens from being damaged by impacts such as walnut shells. This ensures that the camera can continuously and clearly capture the internal condition of the engine and transmit it to the display screen, making it easy for the operator to accurately observe the cleaning status.

[0018] Optionally, the cleaning machine body includes a cylinder and a cylinder cover, which are detachably connected, and a silencer is installed on one side of the cylinder cover.

[0019] By adopting the above technical solution, the main body of the cleaning machine is configured to include a detachably connected cylinder and a cylinder cover, which facilitates the maintenance, cleaning or replacement of parts inside the cleaning machine, improving the maintainability and ease of use of the equipment; a silencer is installed on one side of the cylinder cover, which can effectively reduce the noise generated by the cleaning machine during operation and reduce the impact on the surrounding environment and operators.

[0020] Optionally, a conical sleeve is fixed at one end of the inner circular plate away from the main body of the cleaning machine, and the connecting pipe and the sand suction pipe are both inside the conical sleeve. A fixing part is fixed at one end of the outer plate away from the main body of the cleaning machine, and the fixing part is used to fix and connect to the engine to be cleaned.

[0021] By adopting the above technical solution, the cone sleeve can prevent the carbon deposits and walnut shells from adhering to the baffle plate and increase the absorption area of ​​the suction pipe. The fixing part can be fixedly connected to the engine to be cleaned, so that the walnut shell cleaning machine can be stably connected to the engine during operation, ensuring that the position of the spray gun is relatively fixed, eliminating the need for manual handling, and improving cleaning efficiency and effect.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. The connecting pipe of the spray gun can rotate along its own axis and the air inlet end, and the nozzle is rotatably connected to the connecting pipe with the rotation axes perpendicular to each other. Combined with the first drive device driving the connecting pipe to rotate relative to the air inlet end, and the second drive device driving the nozzle to rotate relative to the connecting pipe, the nozzle end can achieve multi-directional and multi-angle rotation and oscillation. Thus, when using the walnut shell cleaning machine to clean the inside of the engine, the nozzle end can flexibly adjust its position and angle, accurately spraying walnut shells onto various parts inside the engine, thereby cleaning carbon deposits inside the engine from multiple directions and angles, improving cleaning effect and efficiency. 2. The air intake end is fixedly connected to the sand suction pipe, ensuring its stability. The output end of the first motor is coaxially and fixedly connected to the first worm gear, and the connecting pipe is coaxially and fixedly connected to the first worm wheel. The first worm gear and the first worm wheel mesh with each other, enabling mutual rotation between the connecting pipe and the air intake end. Simultaneously, the first dustproof box, which is fitted together on the outer side of the first worm gear and the first worm wheel, is fixedly connected to the inner wall of the sand suction pipe, preventing dust and other impurities from entering the transmission structure of the first worm gear and the first worm wheel, reducing wear and extending their service life. The baffle is fixedly connected to the first motor, providing a stable mounting base for the first motor, allowing the first drive device to operate more stably, and enabling the connecting pipe of the spray gun to rotate flexibly, facilitating multi-directional and multi-angle cleaning of carbon deposits inside the engine. 3. This allows the nozzle end to rotate flexibly relative to the connecting pipe, thereby expanding the spray range and angle of the nozzle end. This helps to clean carbon deposits in different locations and angles inside the engine from multiple angles and directions, improving the cleaning effect of the walnut shell cleaning machine on engine carbon deposits.

The machine body 1 includes a cylinder 11 and a cylinder cover 12, which are detachably connected to facilitate maintenance and cleaning of the inside of the machine body 1. A silencer 14 is installed on one side of the cylinder cover 12. The silencer 14 can be a resistive silencer 14, which can effectively reduce the noise generated by the cleaning machine during operation.

[0033] Reference Figure 2 and Figure 3 The spray gun 2 includes an air inlet 21, a connecting pipe 22, a nozzle end 23, a first drive device 24, and a second drive device 25. One end of the air inlet 21 is connected to an air pump, and the other end is inserted into and fixedly connected to the sand suction pipe 3. The connecting pipe 22 is located inside the sand suction pipe 3 and the two are coaxially arranged. The connecting pipe 22 is rotatably connected to the air inlet 21 along its own axis. The connecting pipe 22 is a rigid pipe and can be made of steel, which is not easily deformed. A first cylinder 221 is fixedly connected to the end of the connecting pipe 22 near the nozzle end 23, and a second cylinder 231 is fixedly connected to the end of the nozzle end 23 near the connecting pipe 22. A sleeve is fixedly coaxially to the end of the first cylinder 221 near the second cylinder 231. The inner wall of the sleeve fits against the outer wall of the second cylinder 231. The second cylinder 231 is inserted into the sleeve, realizing the coaxial rotatable connection between the first cylinder 221 and the second cylinder 231. The first cylinder 221 and the second cylinder 231 are also made of rigid pipes, such as steel pipes.

[0034] Reference Figure 2 and Figure 3 The sandblasting pipe 4 comprises three parts: a feed end connected to the cylinder 11, a connecting end located inside the suction pipe 3, and a rotating end communicating with the nozzle end 23. One end of the feed end of the sandblasting pipe 4 extends into the cylinder 11 from its lower end, while the other end is inserted into the suction pipe 3, avoiding the connecting pipe 22. The connecting end of the sandblasting pipe 4 is located inside the suction pipe 3 and is a rigid pipe, which can be made of steel. The end of the connecting end of the sandblasting pipe 4 furthest from the feed end is coaxially arranged with the suction pipe 3. One end of the rotating end of the sandblasting pipe 4 is rotatably connected to the connecting end, and the other end is rotatably connected to the nozzle end 23. The two ends of the rotating end are rigid pipes, while the middle part is a flexible hose.

[0035] Reference Figure 2 and Figure 3A baffle 5 is fixed on the outer wall of the end of the suction pipe 3 away from the main body 1 of the cleaning machine. The connecting pipe 22 is rotatably connected to the nozzle end 23. The rotation axis of the nozzle end 23 is perpendicular to the rotation axis of the connecting pipe 22. The first driving device 24 is used to drive the mutual rotation between the connecting pipe 22 and the air intake end 21. The second driving device 25 is used to drive the mutual rotation between the nozzle and the connecting pipe 22. This achieves the effect of cleaning the carbon deposits inside the engine from multiple directions and angles. The reason is that the connecting pipe 22 can rotate around its own axis, and the nozzle can rotate perpendicularly relative to the connecting pipe 22, so that the nozzle can change multiple directions to sandblast and clean the carbon deposits.

[0036] Reference Figure 3 and Figure 4 The first driving device 24 includes a first motor 241, a first worm gear 242, and a first worm wheel 243. The first motor 241 can be a common DC motor, which is simple in structure and easy to control; alternatively, a stepper motor can be used, which enables precise angle control. A first dustproof box 244 is fitted around the outer sides of the first worm gear 242 and the first worm wheel 243. The first dustproof box 244 is generally made of plastic, such as polyethylene, which has good sealing and corrosion resistance and is lightweight. The first dustproof box 244 is fixedly connected to the inner wall of the sand suction pipe 3, the baffle 5 is fixedly connected to the first motor 241, the output end of the first motor 241 is coaxially fixedly connected to the first worm gear 242, and the connecting pipe 22 is coaxially fixedly connected to the first worm wheel 243. The first worm gear 242 and the first worm wheel 243 mesh with each other. When the first motor 241 starts, it drives the first worm gear 242 to rotate. The first worm gear 242, through meshing with the first worm wheel 243, drives the connecting pipe 22 to rotate around its own axis. At the same time, the first dustproof box 244 serves as a gas conversion function. One end of the air inlet pipe, located inside the sand suction pipe 3, is inserted into the first dustproof box 244. Gas enters the first dustproof box 244 from the air inlet pipe and then enters the connecting pipe 22.

[0037] Reference Figure 2 and 3The second driving device 25 includes a second motor 251, a second worm gear 252, and a second worm wheel 253. The second motor 251 can be a DC motor or a stepper motor similar to the first motor 241. A second dustproof box 254 is fitted around the outer sides of the second worm gear 252 and the second worm wheel 253, and the second dustproof box 254 is fixedly connected to the first cylinder 221. The second worm gear 252 is coaxially fixed to the outer wall of the second cylinder 231, and the second worm gear 252 meshes with the second worm wheel 253. The baffle 5 includes an inner circular plate 51 and an outer plate 52, which are rotatably connected. One end of the second worm gear 252 passes through the baffle 5 and is rotatably connected to the inner circular plate 51 along its own axis. The second motor 251 is fixedly connected to the inner circular plate 51 and is used to drive the second worm gear 252 to rotate. When the second motor 251 is started, the second motor 251 drives the second worm 252 to rotate. The second worm 252 drives the nozzle to rotate vertically relative to the connecting pipe 22 through meshing transmission with the second worm wheel 253.

The cleaning machine body 1 is equipped with a display screen 13, and the camera 6 is connected to the display screen 13 via a wireless signal. The lens end of the camera 6 is equipped with a light source. The camera 6 can be a common industrial camera 6, which has high resolution and stability, and the light source can be an LED lamp, which has the characteristics of energy saving and high brightness. Through the camera 6 and the display screen 13, the operator can observe the carbon deposit cleaning status inside the engine in real time.

[0039] Reference Figure 5 A power source 6126 is fixedly mounted on the outer wall of the nozzle end 23. The power source 6126 can be a small battery-powered motor. A scraper 62 is fixedly connected to the rotating shaft of the power source 6126. Several bristles 63 are fixedly mounted on the side of the scraper 62 near the lens end of the camera 6. The scraper 62 is used to shield the camera 6. When the lens of the camera 6 is blocked by dust or other obstructions, the power source 6126 drives the scraper 62 to rotate, and the bristles 63 clean the lens of the camera 6.

[0040] Reference Figure 6 A conical sleeve 53 is fixedly mounted on the end of the inner circular plate 51 away from the main body 1 of the cleaning machine. The diameter of the conical sleeve 53 gradually increases as it moves away from the suction pipe 3. Both the connecting pipe 22 and the suction pipe 3 are located inside the conical sleeve 53. A fixing part 54 is fixedly mounted on the end of the outer plate 52 away from the main body 1 of the cleaning machine. The fixing part 54 is used for fixed connection with the engine to be cleaned. The conical sleeve 53 can increase the absorption area of ​​the suction pipe 3. The fixing part 54 can be adapted to the opening structure of the engine; it can be connected by a threaded connection or by an interference fit inserted into the engine opening for fixation, facilitating connection with the engine.

[0041] The implementation principle of the walnut shell cleaning machine in this application embodiment is as follows: the walnut shell cleaning machine drives the connecting pipe 22 to rotate around its own axis through the first driving device 24, and drives the nozzle to rotate perpendicularly relative to the connecting pipe 22 through the second driving device 25, realizing multi-directional and multi-angle rotation of the nozzle, thereby enabling comprehensive cleaning of carbon deposits inside the engine. The camera 6 and display screen 13 facilitate the operator's observation of the cleaning situation, the scraper 62 and brush bristles 63 ensure the cleanliness of the camera 6 lens, the muffler 14 reduces working noise, and the cone sleeve 53 and fixing part 54 ensure the sealing and stability of the connection between the equipment and the engine. Compared with the prior art, it avoids the problems of limited angle of manual rotation of the spray gun 2 and leakage of carbon deposits and walnut shells, thus improving cleaning efficiency and quality.
