Description

Technical Field

[0001] The invention relates to the technical field of diesel engine structures, in particular to a respirator outlet pipe of a diesel engine. Background Art

[0002] The diesel engine breather is an important structure for internal and external gas exchange in the diesel engine. It is mainly used to inhale external air and discharge internal exhaust gas. The diesel engine is an internal combustion engine equipment that burns diesel as a power source. Its fuel diesel is a kind of oil with high viscosity, high ignition point and not easy to burn completely. Although the current diesel engines are improved and optimized for the full combustion of diesel fuel, it is still inevitable that incomplete combustion of diesel will occur in some extreme cases. At this time, dust residue after combustion will be generated. The respirator of the diesel engine serves as a channel for the exchange of air inside and outside the diesel engine. The outlet pipe of the respirator will accumulate residual dust when the diesel engine has incomplete combustion. If the inner wall of the outlet pipe is not cleaned for a long time, it will seriously affect the ventilation of the outlet pipe. For this reason, it is necessary to improve and optimize the outlet pipe structure of the respirator. Summary of the invention

[0082] By adopting the technical solution disclosed in the present invention, it is possible to achieve:

[0083] When using the device, the pipe body 1 is installed on the outlet end of the diesel engine respirator. After long-term use, the inner wall of the pipe body 1 is adhered to dust generated by incomplete combustion of residual diesel. The inner wall of the pipe body 1 is cleaned by the sweeping mechanism 3.

[0084] The stepping hydraulic rod 3-4 works to extend the shaft end, and then the stepping hydraulic rod 3-4 pushes the stepping seat 3-3 to slide on the three-section slide rail 3-2, so that the stepping seat 3-3 drives the support shaft 5-1 to move and extend into the pipeline body 1, and makes the burr of the brush strip 5-3 on the roller 5-2 press against the inner wall of the pipeline body 1, and the telescopic hydraulic rod 4-5 works to push the telescopic frame 4-4 into the pipeline body 1, and clamps the fork frame 9 on the outside of the support shaft 5-1 above the plug 5-4, and makes the driving gear 6-2 mesh with the driven gear 6-3, and starts the driving motor 6-5 to drive the transmission shaft 6-4 to rotate, and the transmission shaft 6-4 drives the driving shaft 6-1 to rotate, and the driving shaft 6-1 drives the roller 5-2 to rotate through the mutually meshing driving gear 6-2 and the driven gear 6-3, and then the roller 5-2 drives the brush strip 5-3 to rotate, and through the brush strip 5- 3. The inner wall of the pipe body 1 is swept and brushed to remove the dust on the inner wall of the pipe body 1. The opening and closing motor 12 is started to drive the opening and closing gear 13 to rotate. The opening and closing gear 13 drives the ring frame 10 to rotate through the meshing ring gear 11. The ring frame 10 drives the cover plate 14 to move to open the guide port 4-2 and move the cover plate 14 away from the bottom of the lifting frame 4-1. The lifting hydraulic rod 4-3 is started to drive the lifting frame 4-1 to descend. The lifting frame 4-1 drives the telescopic frame 4-4 to descend. The telescopic frame 4-4 is against the plug 5-4 through the fork frame 9, thereby pushing the roller 5-2 to descend, thereby driving the brush bar 5-3 to descend to sweep the lower section of the pipe body 1. When the roller 5-2 descends, the potato pushes the spring 8 to compress the spring 8, and then when the fork frame 9 rises and resets, the spring 8 pushes the plug 5-4 upward, thereby moving the roller 5-2 upward and resetting.

[0085] The technical advantages that can be achieved by adopting the above technical solution are as follows:

[0086] 1. The device is provided with a retractable roller 5-2 and a brush strip 5-3, so that the roller 5-2 can be moved into the pipe body 1, and the dust particles adhering to the inner wall of the pipe body 1 can be cleaned by the brush strip 5-3 by driving the roller to rotate and move up and down;

[0087] 2. The device installs the roller 5-2 on the stepping seat 3-3, installs the driving shaft 6-1 on the telescopic frame 4-4, and installs the telescopic frame 4-4 on the lifting frame 4-1, so that when the pipeline body 1 realizes normal ventilation and exhaust, the roller 5-2, the telescopic frame 4-4 and other structures are moved out of the inner cavity of the pipeline body 1 to ensure the smooth flow of the pipeline body 1.

[0088] For those skilled in the art, they can modify the technical solutions described in the aforementioned embodiments and make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
