[0009] Preferably, a tough pad is fixedly connected to the inner side of the adapter ring plate, and the end of the tough pad away from the adapter ring plate is fixedly connected to the ring support, wherein the tough pad is used to reset the adapter ring plate and avoid blocking interference between the adapter ring plate and the ring support.

[0010] Preferably, the outer side of the inner link is fixedly connected to a limit plate, and the limit plate is used to control the deflection range of the inner link; An air pipe is sleeved on the outer side of the inner connecting ring at the bottom. An end of the air pipe away from the inner connecting ring is fixedly connected to a transition pipe, and the transition pipe is fixedly installed on the outer side of the combustion chamber.

[0011] Preferably, an arc-shaped groove is provided at the top of the inner connecting ring, and a sealing plate is slidably fitted in the arc-shaped groove, and the top of the sealing plate is squeezed and fitted with the adapter ring plate, wherein the sealing plate is used to seal the air port at the top of the trachea, and an insert plate is fixedly connected to the outer side of the sealing plate.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1.

At the same time, when the piston moves down to the limit distance, its top end will exceed the bottom end height of the inner connecting ring. Therefore, when the piston moves upward, the mixed gas inside the combustion chamber will be above the adapter ring plate, and the adapter ring plate will not be deflected outward due to the compression of the mixed gas.

[0019] 4. Since the bottom of the plugging head is connected to the return spring through a sliding disk, the plugging head will slowly move downward and compress the return spring. The return spring not only resets the plugging head, but also slowly separates the plugging head from the embedded disk, thereby increasing the reaction time between the activated carbon and zeolite and sulfur dioxide.

DETAILED DESCRIPTION

[0032] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. It should be noted that the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0033] See also Figures 1 to 11 , the present invention provides a technical solution: Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 and Figure 8 As shown, it includes a cylinder mechanism 3 for discharging dust in the cylinder, and the cylinder mechanism 3 is arranged in the frame body 1; The outer end surface of the frame body 1 is connected to a flange 2 via fasteners; The exhaust mechanism 4 is used to discharge the exhaust gas generated during the operation of the cylinder. The exhaust mechanism 4 is symmetrically arranged on both sides of the frame body 1.

[0034] The cylinder mechanism 3 includes a center wheel 31, which is rotatably mounted inside the frame body 1. A connecting shaft 32 is fixedly mounted on the outer side of the center wheel 31. The connecting shaft 32 and the center wheel 31 are not concentric. A first connecting handle 33 and a second connecting handle 35 are fixedly connected to the outer side of the connecting shaft 32. A first cylinder assembly 34 is provided at one end of the first connecting handle 33 away from the connecting shaft 32; A combustion chamber 36 is fixedly mounted on the outside of the frame 1. A cylinder liner 52 is fixedly mounted inside the combustion chamber 36. A hollow sleeve 37 is slidably fitted inside the cylinder liner 52. An inner connecting shaft 53 is fixedly connected to the inner portion of the hollow sleeve 37. The outer portion of the inner connecting shaft 53 is rotatably connected to the second connecting handle 35. External driving force causes the center wheel 31 to idle. When the second connecting handle 35, which is connected to the center wheel 31 via the connecting shaft 32, moves away from the combustion chamber 36, the hollow sleeve 37, which is connected to the second connecting handle 35 via the inner connecting shaft 53, moves downward with the piston 51. This causes a mixture of diesel and air to enter the combustion chamber 36 through the intake port. The first and second piston rings 39 and 30, located within the ring groove structure of the piston 51, act as a cylinder seal, preventing gas leaks and providing heat conduction. The combined oil ring 38 scrapes away excess diesel fuel, ensuring lubrication of the cylinder wall. The rotational force of the center wheel 31 then causes the piston 51 to move upward, compressing and igniting the diesel-air mixture. The compressed mixture then pushes the piston 51 in the opposite direction, causing it to move outward again. The exhaust gas in the combustion chamber 36 is then discharged out the exhaust port. When the piston 51 maintains normal motion, the external force acting on the center wheel 31 is decoupled, allowing the piston 51 to rotate and convert internal energy into mechanical energy.

[0035] The combustion chamber 36 is used for intake air, compression ignition of diesel and exhaust treatment; The top of the hollow sleeve 37 is fixedly connected to a combined oil ring 38. A first piston ring 39 is set on the top of the combined oil ring 38. A second piston ring 30 is set on the top of the first piston ring 39. A piston 51 is set on the top of the second piston ring 30. The combined oil ring 38, the first piston ring 39 and the second piston ring 30 are engaged with the ring groove structure of the piston 51 body; A groove is provided on the inner side of the cylinder liner 52, and inner connecting rings 54 are symmetrically connected to the upper and lower ends of the inner cavity of the groove. A ring support 55 is fixedly installed on the bottom of the inner connecting ring 54 at the top, and an adapter ring plate 57 is installed inside the ring support 55 through the rotation of the ring shaft, wherein the inner side of the adapter ring plate 57 is slidably adapted to the piston 51; the abrasive particles formed by the dust in the air and the diesel impurities will generate friction and wear on the sliding connection part of the cylinder liner 52 and the piston 51. When brittle impurities enter the sliding connection part of the cylinder liner 52 and the piston 51, one of the cylinder liner 52, the inner connecting ring 54 and the adapter ring plate 57 will slide and adapt to the piston 51 at a certain stage, and squeeze and crush the brittle impurities. The piston 51 and the piston ring are both made of cast iron, so the brittle impurities will not cause damage to the piston 51 and the piston ring.

[0036] The adapter ring plate 57 contacts and squeezes the particulate impurities adhering to the outside of the piston 51, so that the adapter ring plate 57 crushes the brittle impurities, while the hard impurities cause the adapter ring plate 57 to deflect outwards. A resilient pad 58 is fixedly connected to the inner side of the adapter ring plate 57. The end of the resilient pad 58 away from the adapter ring plate 57 is fixedly connected to the ring support 55. The resilient pad 58 is used to reset the adapter ring plate 57 and prevent obstruction and interference between the adapter ring plate 57 and the ring support 55. The outer side of the inner link 54 is fixedly connected to a limit plate 56, which is used to control the deflection range of the inner link 54; The outer side of the inner connecting ring 54 at the bottom is provided with an air pipe 59, and the end of the air pipe 59 away from the inner connecting ring 54 is fixedly connected to the transition pipe 503, and the transition pipe 503 is fixedly installed on the outer side of the combustion chamber 36; when hard impurities enter the part where the cylinder liner 52 and the piston 51 are slidably connected, the cylinder liner 52, the inner connecting ring 54 and the adapter ring plate 57 cannot crush the hard impurities by squeezing, but when the hard impurities are between the adapter ring plate 57 and the piston 51, the hard impurities will squeeze the adapter ring plate 57, and the squeezed adapter ring plate 57 will be deflected outward through the ring support 55, wherein the limit plate 5 6 will limit the deflection range of the adapter ring plate 57, and at the same time, the adapter ring plate 57 will stretch the tough pad 58, and then the adapter ring plate 57 that deflects outward will squeeze the sealing plate 50, so that the sealing plate 50 will move outward along the arc groove opened on the top of the inner link 54, thereby opening the air pipe 59 that was originally blocked by the sealing plate 50, and then the external air intake equipment connected to the transition pipe 503 will generate suction in the air pipe 59, and finally discharge part of the mixed gas of diesel, air and impurities outward for treatment, and at the same time prevent hard impurities from being in the combustion chamber 36 for a long time and causing wear to its internal components.

[0037] An arc-shaped groove is formed at the top of the inner connecting ring 54, and a blocking plate 50 is slidably fitted into the arc-shaped groove. The top of the blocking plate 50 is squeezed and fitted with the adapter ring plate 57. The blocking plate 50 is used to block the air port at the top of the air pipe 59. The outer side of the blocking plate 50 is fixedly connected to the plug plate 501. The insert plate 501 is inserted into the inner side of the inner connecting ring 54 and extends to the outside thereof. A folding plate 502 is provided at the end of the insert plate 501 away from the sealing plate 50. The folding plate 502 is fixedly connected to the outer side of the adapter ring plate 57. Therefore, when the adapter ring plate 57 is reset, the folding plate 502 will squeeze the insert plate 501 inward, and the squeezed insert plate 501 will carry the sealing plate 50 to re-seal the air pipe 59. In addition, the adapter ring plate 57, the ring support 55, and the inner connecting ring 54 are all arranged in the lower half of the combustion chamber 36. At the same time, when the piston 51 moves downward to the limit distance, its top end will exceed the bottom end height of the inner connecting ring 54. Therefore, when the piston 51 moves upward, the mixed gas inside the combustion chamber 36 will be above the adapter ring plate 57, and the adapter ring plate 57 will not be deflected outward due to the compression of the mixed gas. The other cylinder assembly 34 is exactly the same as the above-mentioned device, but the lifting and lowering sequence of the piston 51 is reversed.

[0038] The top end of the folding plate 502 is fixedly connected to the adapter ring plate 57 , and the folding plate 502 is used to reset the blocking plate 50 .

[0039] like Figure 9 、 Figure 10 and Figure 11 As shown, the exhaust mechanism 4 includes an intermediate pipe 41, and the outer end surface of the intermediate pipe 41 is fixedly connected to the exhaust pipe 42, wherein the intermediate pipe 41 is used to cool the exhaust gas to avoid burns and wear on the exhaust pipe 42; A pipe 43 is fixedly connected to the outside of the intermediate pipe 41, and one end of the pipe 43 away from the intermediate pipe 41 is connected to the exhaust port of the combustion chamber 36; A polished rod 44 is fixedly installed inside the pipe 43, and the bottom of the polished rod 44 is connected to a return spring 45 through a plate, and the top of the return spring 45 is fixedly connected to a sliding plate 46, wherein a large number of air holes are opened on the surface of the sliding plate 46, and the return spring 45 is used to reset the sliding plate 46, and the sliding plate 46 is slidably adapted to the polished rod 44; when the exhaust gas is discharged outward from the exhaust port of the combustion chamber 36, the exhaust gas will squeeze the plugging head 47 downward, wherein the outer side of the plugging head 47 is fixedly connected to a filter screen 49, and the filter screen 49 is provided with activated carbon and zeolite. At this time, the activated carbon and zeolite will absorb and filter the sulfur dioxide in the exhaust gas, thereby preventing the subsequent reaction of sulfur dioxide with condensed water to generate sulfuric acid and causing corrosion to the inner wall of the pipe body. In addition, the bottom of the plugging head 47 is connected to the return spring 45 through the sliding plate 46, so the plugging head 47 will slowly move downward and compress the return spring 45, wherein the return spring 45 not only plays a role in resetting the plugging head 47, but also plays a role in slowly separating the plugging head 47 from the embedded plate 48, thereby increasing the reaction time between the activated carbon and zeolite and sulfur dioxide.

[0040] A plugging head 47 is fixedly connected to the top of the sliding plate 46, and an embedded plate 48 is slidably adapted on the outside of the plugging head 47. The embedded plate 48 is fixedly installed inside the pipe 43, and a filter screen 49 is fixedly connected to the outside of the plugging head 47; the plugging head 47 is frustum-shaped, and initially the plugging head 47 is sealed with the embedded plate 48, but as the plugging head 47 moves downward, a gap is created between the two, and eventually the exhaust gas passes through the gap into the intermediate pipe 41 for cooling, and is finally discharged from the exhaust pipe 42.

[0041] The filter 49 contains activated carbon and zeolite.

[0042] When the present invention is in use: first, the center wheel 31 is allowed to idle by external driving force. When the No. 2 connecting handle 35 connected to the center wheel 31 through the connecting shaft 32 moves in a direction away from the combustion chamber 36, the hollow sleeve 37 connected to the No. 2 connecting handle 35 through the inner connecting shaft 53 will move the piston 51 downward. At this time, the diesel and air mixture will enter the combustion chamber 36 through the air intake. Finally, the compressed mixture will push the piston 51 in the opposite direction to move the piston 51 outward again. Then, the exhaust gas in the combustion chamber 36 will be discharged outward from the exhaust port. When the movement of the piston 51 can be maintained normally, the external drive on the center wheel 31 is separated, and the rotation of the center wheel 31 is driven by the operation of the piston 51.

[0043] Abrasive particles formed by dust in the air and diesel impurities will generate friction and wear on the sliding connection between the cylinder liner 52 and the piston 51. When brittle impurities enter the sliding connection between the cylinder liner 52 and the piston 51, one of the cylinder liner 52, the inner connecting ring 54 and the adapter ring plate 57 will slide and adapt with the piston 51 at a certain stage, and squeeze and crush the brittle impurities. The piston 51 and the piston ring are both made of cast iron, so the brittle impurities will not cause damage to the piston 51 and the piston ring. When hard impurities are between the adapter ring plate 57 and the piston 51, the hard impurities will squeeze the adapter ring plate 57, and the squeezed adapter ring plate 57 will be deflected outward through the ring support 55, wherein the limit plate 56 will limit the deflection range of the adapter ring plate 57, and at the same time the adapter ring plate 57 will stretch the tough pad 58, and then the outward deflected adapter ring plate 57 will squeeze the sealing plate 50, so that the sealing plate 50 will move outward along the arc groove opened at the top of the inner connecting ring 54, and then the external air intake equipment connected to the transition pipe 503 will generate suction in the air pipe 59, and finally discharge part of the mixed gas of diesel, air and impurities outward. The outer side of the adapter ring plate 57 is fixedly connected to a folding plate 502. Therefore, when the adapter ring plate 57 is reset, the folding plate 502 will squeeze the insert plate 501 inward, and the squeezed insert plate 501 will bring the sealing plate 50 to re-seal the air pipe 59. In addition, the adapter ring plate 57, the ring support 55, and the inner connecting ring 54 are all arranged in the lower half of the combustion chamber 36. At the same time, when the piston 51 moves downward to the limit distance, its top end will exceed the bottom end height of the inner connecting ring 54. Therefore, when the piston 51 moves upward, the mixed gas inside the combustion chamber 36 will be above the adapter ring plate 57, and the adapter ring plate 57 will not be deflected outward due to the compression of the mixed gas.

[0044] When exhaust gas is discharged from the exhaust port of the combustion chamber 36, it will squeeze the plug 47 downward. The outer side of the plug 47 is fixedly connected to a filter 49, and the filter 49 is provided with activated carbon and zeolite. The activated carbon and zeolite absorb and filter the sulfur dioxide in the exhaust gas, thereby preventing the subsequent reaction of sulfur dioxide with condensed water to form sulfuric acid and corrode the inner wall of the tube body. In addition, the bottom of the plug 47 is connected to the return spring 45 via the sliding plate 46. Therefore, the plug 47 will slowly move downward and compress the return spring 45. The return spring 45 not only resets the plug 47, but also slowly separates the plug 47 from the embedded plate 48, thereby increasing the reaction time between the activated carbon and zeolite and the sulfur dioxide. The plugging head 47 is in the shape of a cone. Initially, the plugging head 47 is sealed with the embedded disk 48. However, as the plugging head 47 moves downward, a gap is formed between the two. Eventually, the exhaust gas enters the intermediate pipe 41 through the gap for cooling, and is finally discharged from the exhaust pipe 42.

[0045] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Various changes made by ordinary technicians in this field based on the above concepts without creative work fall within the scope of protection of the present invention.
