The slag crane 2 is a prior art in the art, and the specific structure of this embodiment is not repeated. The slag crane 2 is used for the transportation and feeding of garbage in the garbage dump 1. The crusher 3 is arranged in the garbage dump 1. The slag crane 2 grabs the garbage and sends it to the crusher 3. The two ends of the belt conveyor 4 are respectively connected to the outlet of the crusher 3 and the feeding port 5 of the incinerator 6. The crushed garbage falls from the outlet onto the belt conveyor 4 and is transported to the feeding port 5 of the incinerator 6 through the belt conveyor 4.

[0018] A buffer chamber 7 connected to the feeding port 5 is provided in the incinerator 6. The buffer chamber 7 is used to temporarily store the garbage transported from the belt conveyor 4. Since the buffer chamber 7 is arranged in the incinerator 6, the high temperature in the furnace is transferred to the buffer chamber 7, which can heat and dry the garbage in the buffer chamber 7 to evaporate the moisture in the garbage for subsequent combustion. A baffle control assembly 8 for opening and closing the bottom opening is provided in the buffer chamber 7. The heated uniform garbage falls into the incinerator 6 for full combustion through the baffle control assembly 8. A material level detector 9 for detecting full material is provided in the buffer chamber 7, and the baffle control assembly 8, the driving motor of the belt conveyor 4 and the material level detector 9 are all electrically connected to the control circuit.

[0019] Among them, the baffle control assembly 8 includes an upper baffle 82, a lower baffle 84, and an upper motor 81 and a lower motor 83 for driving the upper baffle 82 and the lower baffle 84 to rotate respectively. The buffer chamber 7 is divided into an upper feed chamber and a lower feed chamber by the upper baffle 82 and the lower baffle 84, and the material level detector 9 is arranged in the upper feed chamber. Specifically, first, the upper baffle 82 and the lower baffle 84 are both in a closed state, the belt conveyor 4 transports the crushed garbage to the feed port 5 and stores the garbage in the upper feed chamber for preliminary drying. When the garbage in the upper feed chamber is piled to a certain height and is detected by the material level detector 9, it proves that the upper feed chamber is full. The material level detector 9 sends a signal to the control circuit. After receiving the signal, the garbage belt conveyor 4 is first suspended to prevent excessive garbage from clogging the feed port. At the same time, the control circuit sends a command to the upper motor 81, and the upper motor 81 opens the upper baffle 82, and the garbage is The garbage falls from the upper feeding chamber into the lower feeding chamber for secondary drying, and then the upper motor 81 drives the upper baffle 82 to close, and the garbage belt conveyor 4 is started to continue to transport garbage to the upper feeding chamber; when it is detected that the upper feeding chamber is full again, the material level detector 9 sends a signal to the control circuit, and the control circuit line sends a command to the lower motor 83, and the lower motor 83 drives the lower baffle 84 to put all the garbage in the lower feeding chamber into the furnace for combustion. After the garbage is put in, the lower baffle 84 is closed, and then the upper motor 81 is commanded to drive the upper baffle 82 to open, and the above operations are repeated.

[0020] As attached Figure 2 As shown, the output ends of the upper motor 81 and the lower motor 83 are both connected to a reduction gear box 10, and the output shafts of the gear box are respectively connected to one side of the upper baffle 82 and the lower baffle 84.

[0021] In the above embodiment, preferably, the upper baffle 82 and the lower baffle 84 are arranged at an angle and in opposite directions, and the speed is controllable. Secondly, the garbage can be orderly and evenly dropped from the upper feed chamber into the lower feed chamber, and evenly dropped from the lower feed chamber into the incinerator 6, avoiding falling in piles, ensuring that the middle and inside of the garbage pile are fully dried, so that it can be fully burned in the furnace, thereby improving the garbage combustion rate and reducing fuel waste.

[0022] Guard plates 11 are provided on both sides of the belt conveyor 4 to prevent piles of crushed garbage from rolling down from both sides of the belt conveyor 4 during the transmission process, thereby increasing the workload.

[0023] When the upper feeding chamber is full, the belt conveyor 4 will stop conveying, while the crusher 3 is continuously working, and the crushed garbage will continue to be transported from the outlet to one end of the belt conveyor 4. In order to avoid the garbage filling up and overflowing the belt conveyor 4 when the belt conveyor 4 is suspended, thereby increasing the workload, a conveying hopper 12 is provided at the connection between the outlet of the crusher 3 and one end of the belt conveyor 4 to play a temporary storage and buffering role.
