DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Example: See Figure 1-5The utility model discloses an exhaust pipe of an internal combustion engine which is easy to clean, comprising an exhaust pipe 1, a first connecting pipe 3 is arranged on one side of the exhaust pipe 1, a second connecting pipe 5 is arranged on the other side of the exhaust pipe 1, a scraper 6 is arranged in a movable abutment inside the exhaust pipe 1, a transmission mechanism 4 is arranged on the inner wall of the exhaust pipe 1, and the scraper 6 can be slid better through the setting of the transmission mechanism 4 to clean the attached dust in the exhaust pipe 1; a plurality of dust removal mesh holes 8 are opened on the upper wall of the exhaust pipe 1, a mounting seat 9 is arranged on the top surface of the exhaust pipe 1, a baffle 2 is slidably arranged in the mounting seat 9, and a device for removing dust from the exhaust pipe 1 is arranged on the mounting seat 9 The fixing bolts of the fixed baffle 2, through the setting of the baffle 2 and the dust removal mesh 8, can maintain the air tightness of the exhaust pipe 1 when it is not clean, so that the silencer and other components inside the exhaust pipe 1 can work normally; the scraper 6 is symmetrically provided with guide holes, and the inside of the exhaust pipe 1 is symmetrically provided with two guide columns for cooperating with the guide holes to limit the sliding movement. The middle part of the scraper 6 is provided with an installation groove for installing the silencer material. Through the setting of the guide column and the guide hole, the scraper 6 can be slid more smoothly, so that the scraper 6 presses the side wall of the exhaust pipe 1, thereby improving the scraping efficiency of the scraper 6.

[0021] In the utility model, a connecting rope 11 is provided on the guide column on one side of the transmission mechanism 4, and the connecting rope 11 is fixed on the scraper 6. An adjusting wheel 10 for driving the connecting rope 11 to slide is provided in the transmission mechanism 4. Through the setting of the connecting rope 11 and the adjusting wheel 10, the scraper 6 can be better driven to slide in the exhaust pipe 1; a worm wheel 13 is provided on the upper part of the adjusting wheel 10, and a worm 12 for meshing with the worm wheel 13 is provided at the side end of the worm wheel 13, and an adjusting knob 7 is coaxially connected to the end of the worm 12. Through the setting of the worm wheel 13 and the worm 12, the scraper 6 can be better adjusted and the exhaust pipe 1 can be prevented from vibrating and affecting the service life of the scraper 6 when in use; the inner sides of the first connecting tube 3 and the second connecting tube 5 are provided with a protective film for isolation and protection. Through the setting of the protective film, the first connecting tube 3 and the second connecting tube 5 can be better isolated and protected, and subsequent dust cleaning is convenient.

[0022] Working principle: When using the utility model, first remove the connecting bolts that fix the exhaust pipe 1. The setting of the protective film can better isolate and protect the first connecting pipe 3 and the second connecting pipe 5, and facilitate the subsequent dust cleaning. Then unscrew the fixing bolts on the mounting seat 9, and then slide the baffle 2 to open the dust removal mesh 8. Then turn the adjusting knob 7 to make the worm 12 drive the worm wheel 13 to rotate, and the adjusting wheel 10 at the bottom of the worm wheel 13 rotates. The setting of the worm wheel 13 and the worm 12 can better adjust the scraper 6 and prevent the exhaust pipe 1 from vibrating during use, which affects the service life of the scraper 6. The rotating adjusting wheel 10 drives the scraper 6 to slide in the exhaust pipe 1 through the connecting rope 11. During the sliding process, the dust on the side wall of the exhaust pipe 1 is scraped off by the scraper 6 and finally discharged through the dust removal mesh 8. At this point, the dust cleaning of the exhaust pipe 1 is completed.
