A fixed box is fixedly connected to the top of the support frame, and a connecting pipe is fixedly connected to the right side of the fixed box. The bottom end of the connecting pipe is fixedly connected to one side of the top of the incinerator, and a feed hopper is provided at the top of the connecting pipe. The crushing mechanism, located on one side of the feed hopper, is used to crush the waste, facilitating its incineration. The preheating mechanism, located inside the connecting pipe, is used to preheat the waste so that it burns faster after entering the incinerator. The vibration mechanism, located inside the connecting pipe, is used to prevent blockage of the connecting pipe.

[0007] Furthermore, the scraping mechanism includes a combustion chamber disposed inside the incinerator, a rotating column rotatably connected to the top center of the combustion chamber, a scraper fixedly connected to the outer surface of the rotating column, and a motor fixedly disposed at the top center of the incinerator, the output shaft of the motor being fixedly connected to the rotating column.

[0008] Furthermore, the crushing mechanism includes two crushing rollers rotatably disposed inside the feed hopper. A bracket is fixedly connected to the right side of the feed hopper, and a second motor is fixedly connected to the top of the bracket. A first rotating shaft is fixedly connected to the output shaft of the second motor. The first rotating shaft is rotatably connected to the feed hopper. Two worm gears are fixedly connected to the first rotating shaft. Each of the two worm gears has an inner arc connected to a worm wheel. A second rotating shaft is fixedly connected to the two worm wheels. The two second rotating shafts are fixedly connected to the two crushing rollers.

[0009] Furthermore, the preheating mechanism includes an air outlet located on the left side of the incinerator. One end of the air outlet is fixedly connected to a connecting pipe. The connecting pipe has a preheating chamber and a feeding chamber inside. The top end of the connecting pipe is fixedly connected to the preheating chamber, and an air outlet is located on one side of the preheating chamber.

[0010] Furthermore, the vibration mechanism includes a vibrating plate movably disposed inside the feeding chamber, a sliding groove is provided on the left side inside the connecting pipe, a spring plate is fixedly connected to the bottom side inside the fixed box, and the vibrating plate passes through the sliding groove and is fixedly connected to the top end of the spring plate.

[0011] Furthermore, a rack is fixedly connected to the top left side of the spring plate, the rack is meshed with a half gear, and a rotating shaft three is fixedly connected to the half gear, the rotating shaft three being rotatably connected to the fixed box.

[0012] Furthermore, a bevel gear is fixedly connected to the outer surface of the rotating shaft three, a bevel gear two is meshed with the bevel gear one, a rotating shaft four is fixedly connected to the left end of the bevel gear two, and the rotating shaft four is rotatably connected to the fixed box.

[0014] In summary, this application includes at least one of the following beneficial technical effects: 1. This solution starts motor two, whose output shaft drives shaft one to rotate. Shaft one drives two worm gears to rotate, which in turn drives two worm wheels to rotate. These worm wheels then drive two shafts two to rotate, which in turn drive two crushing rollers to rotate. During their relative rotation, the two crushing rollers effectively crush the waste entering the feed hopper, improving the incineration efficiency. Furthermore, due to the high transmission ratio and self-locking properties of the worm gears and worm wheels, the crushing rollers operate stably during waste crushing, preventing reverse rotation or jamming. 2. In this solution, the first rotating shaft drives the second sprocket to rotate, and through linkage, the half gear rotates. The rotation of the half gear drives the rack to move upward, and at the same time drives the top of the spring plate to move upward, causing the vibrating plate to move upward. When the vibrating plate rotates to the position without gears, the spring plate can drive the vibrating plate to rebound. Continuous reciprocating movement can generate vibration, preventing the garbage inside the feeding chamber from clogging. 3. This solution starts the first motor, whose output shaft drives the rotating column to rotate, which in turn drives the scraper to rotate. This scrapes the inner wall of the incineration chamber, preventing excessive dust accumulation from affecting the incineration efficiency. In addition, the scraper can scrape off the garbage residue attached to the inner wall of the incineration chamber during rotation, preventing the garbage residue from accumulating on the inner wall of the incineration chamber and improving the incineration effect of the incinerator. 4. In this design, hot smoke is discharged into the preheating chamber through the air outlet. The smoke circulating inside the preheating chamber is also discharged through the air outlet. The smoke circulating inside the preheating chamber can heat the material feeding chamber, and the temperature of the waste in the feeding chamber gradually increases, which is beneficial to the subsequent incineration process. At the same time, the design of the preheating mechanism makes full use of the hot smoke generated during the incineration process, improving energy efficiency. In addition, preheating can also evaporate the moisture in the waste, reducing the water vapor generated during the incineration process, thereby reducing corrosion of the incineration chamber and extending the service life of the incinerator.

[0015] This invention can crush garbage, scrape off the garbage residue adhering to the inner wall of the incineration chamber, and preheat the garbage to evaporate the moisture in the garbage, thereby reducing the water vapor generated during the incineration process and improving the incineration efficiency.

[0024] The implementation principle of a waste-to-energy power generation device according to an embodiment of this application is as follows: waste is poured into the feed hopper 11, and at the same time, the second motor 15 is started. The output shaft of the second motor 15 drives the first rotating shaft 16 to rotate, the first rotating shaft 16 drives the two worm gears 17 to rotate, the two worm gears 17 drive the two worm wheels 18 to rotate, the two worm wheels 18 drive the two second rotating shafts 19 to rotate, and the two second rotating shafts 19 drive the two crushing rollers 13 to rotate, thereby crushing the waste. The crushed waste enters the incinerator 1 through the connecting pipe 12 for incineration. At the same time, the rotating shaft 16 drives the sprocket 2 33 to rotate. The sprocket 2 33 drives the sprocket 1 32 to rotate through the chain 34. The sprocket 1 32 drives the rotating shaft 4 31 to rotate. The rotating shaft 4 31 drives the bevel gear 2 30 to rotate. The bevel gear 2 30 drives the bevel gear 1 29 to rotate. The bevel gear 1 29 drives the rotating shaft 3 28 to rotate. The rotating shaft 3 28 drives the half gear 27 to rotate. The rotation of the half gear 27 drives the rack 26 to move upward, and at the same time drives the top of the spring plate 25 to move upward, so that the vibrating plate 24 moves upward. When the vibrating plate 24 rotates to the position without gears, the spring plate 25 drives the vibrating plate 24 to rebound. The continuous reciprocating movement can generate vibration and prevent the waste inside the feeding chamber 21 from getting blocked. After feeding is completed, valve 22 is closed and incineration begins. By starting motor 5, the output shaft of motor 5 drives the rotating column 7 to rotate, and the rotating column 7 drives the scraper 8 to rotate, which can scrape the inner wall of the incineration chamber 6 to prevent excessive dust accumulation from affecting the incineration efficiency. In addition, during the rotation, the scraper 8 can scrape off the garbage residue attached to the inner wall of the incineration chamber 6, preventing the garbage residue from accumulating on the inner wall of the incineration chamber 6 and improving the incineration effect of the incinerator 1. During the incineration of waste, hot smoke is discharged into the preheating chamber 20 through the air outlet. The smoke circulating inside the preheating chamber 20 is also discharged through the air outlet. The smoke circulating inside the preheating chamber 20 can heat the feeding chamber 21, and the temperature of the waste in the feeding chamber 21 gradually increases, which is beneficial to the subsequent incineration process. At the same time, the design of the preheating mechanism makes full use of the hot smoke generated during the incineration process, improving energy efficiency. In addition, preheating can also evaporate the moisture in the waste, reduce the water vapor generated during the incineration process, thereby reducing the corrosion of the incineration chamber 6 and extending the service life of the incinerator 1. Waste enters the incineration chamber 6 for combustion, releasing a large amount of heat during the process. The heat in the incineration chamber 6 is transferred to the adjacent liquid storage chamber 2. The liquid storage chamber 2 contains water, which absorbs heat and becomes hot, turning into high-temperature and high-pressure steam. The steam in the liquid storage chamber 2 flows into the impeller 3. The high pressure and kinetic energy of the steam impact the blades of the generator 4, driving the impeller to rotate. At this time, the thermal energy and kinetic energy of the steam are converted into the mechanical energy of the generator 4, which drives the rotor of the generator 4 to rotate synchronously, ultimately converting mechanical energy into electrical energy. Example 2

[0025] The difference between this embodiment and Embodiment 1 is that pads are provided at each of the four corners of the bottom of the incinerator 1. These pads are made of rubber, which has good elasticity and wear resistance, increasing the friction between the incinerator 1 and the ground. This prevents the incinerator 1 from sliding or shifting during use, ensuring the stability and safety of the equipment. The pads are trapezoidal in shape, with a larger bottom area than top area. This design increases the contact area between the pads and the ground, further improving the stability of the equipment.
