[0020] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0021] In the following description, many specific details are set forth in order to fully understand the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the present invention is not limited by the specific embodiments disclosed in the following specification.

[0022] Embodiment 1: As Figures 1 - 4 shown, the present invention provides a technical solution: an automatic feeding device for a biomass fuel boiler, including a processing box 1. A storage box 2 is fixedly connected to the bottom end of one side of the processing box 1. A delivery pipe 4 is communicated with the top end of the storage box 2. A first storage box 7 is arranged at the bottom end of the delivery pipe 4. A limiting round block 10 is fixedly connected to the outer peripheral side of the first storage box 7. A second storage box 11 is communicated with the bottom end of the first storage box 7. A sliding device 9 is fixedly connected to one side of the inner wall of the processing box 1. A slide block 20 is slidably connected to the inside of the sliding device 9. A discharge port 15 is fixedly connected to the bottom end of the slide block 20. A cover plate 16 is movably connected to the bottom end of one side of the discharge port 15. An electric telescopic shaft 14 is fixedly connected to one side of the discharge port 15. One end of the electric telescopic shaft 14 is fixedly connected to one side of the inner wall of the processing box 1. A support shaft 21 is fixedly connected to the bottom end of the processing box 1. A baffle 13 is fixedly connected to one side of the inner wall of the processing box 1. The baffle 13 and the discharge port 15 are symmetric left and right. A fixed rod 6 is fixedly connected to one side of the limiting round block 10. A clamping block 12 is fixedly connected to the bottom end of the fixed rod 6. One side of the clamping block 12 is fixedly connected to one side of the support shaft 21. A micro pump 3 is arranged at the junction of the delivery pipe 4 and the storage box 2.

[0023] In this embodiment, the processing box 1 is provided to facilitate the storage and processing of fuel. Then, the micro pump 3 can be used to extract the fuel inside the storage box 2, so that the fuel flows into the first storage box 7 through the delivery pipe 4. Then, the first storage box 7 and the second storage box 11 can be connected together through a rubber sealing ring. After that, the fuel will flow from the first storage box 7 and the second storage box 11 into the inside of the discharge port 15. A gravity sensor (the model of this gravity sensor is MXC6225XU) is provided at the bottom end of the baffle 13. When the discharge port 15 stores the preset weight, a signal can be sent through the gravity sensor, so that the electric telescopic shaft 14 pushes the slider 20 to move along one side of the sliding device 9. During the movement of the slider 20, the discharge port 15 can be driven to move synchronously. When the discharge port 15 moves to the preset position and can be separated from the baffle 13, the cover plate 16 will open under the action of gravity, so that the fuel can fall from the inside of the discharge port 15 into the inside of the processing box 1.

[0024] Embodiment 2: As Figures 1 - 4 shown, a heat insulation plate 18 is fixedly connected to the middle inside of the processing box 1, a leakage plate 17 is fixedly connected to the inside of the processing box 1, a discharge port 19 is provided on one side of the bottom end of the processing box 1, and the heat insulation plate 18 and the leakage plate 17 are symmetrically arranged up and down.

[0025] In this embodiment, the heat insulation plate 18 can prevent the high temperature generated during fuel combustion from damaging devices such as the discharge port 15, the slider 20, and the sliding device 9, resulting in a reduction in their service life. When the debris generated by the fuel after combustion is completed, it will flow from the leakage plate 17 into the bottom end inside the processing box 1. Then, the discharge port 19 can be used to discharge the debris generated by the fuel. A valve is provided on one side of the discharge port 19 to facilitate the control of the working state of the discharge port 19.

[0026] Working principle of this embodiment: When in use, first, the processing box 1 is convenient for storing and processing fuel. Then, the micro pump 3 can extract the fuel inside the storage box 2, so that the fuel flows into the inside of the first storage box 7 through the delivery pipe 4. Then, the first storage box 7 and the second storage box 11 can be connected together through a rubber sealing ring. After that, the fuel will flow from the first storage box 7 and the second storage box 11 into the inside of the discharge port 15, and a gravity sensor (the model of this gravity sensor is MXC6225XU) is arranged at the bottom end of the baffle 13. When the discharge port 15 stores the preset weight, a signal can be sent through the gravity sensor, so that the electric telescopic shaft 14 pushes the slider 20 to move along one side of the sliding device 9. During the movement of the slider 20, the discharge port 15 can be driven to move synchronously. When the discharge port 15 moves to the preset position and the discharge port 15 can be separated from the baffle 13, the cover plate 16 will open under the action of gravity, so that the fuel can fall from the inside of the discharge port 15 into the inside of the processing box 1. The heat insulation plate 18 can prevent the high temperature generated during fuel combustion from damaging equipment such as the discharge port 15, the slider 20 and the sliding device 9, resulting in a reduction in their service life. When the debris generated by the fuel after combustion is completed, it will flow from the leakage plate 17 into the bottom end of the inside of the processing box 1. Then, the discharge port 19 can be used to discharge the debris generated by the fuel. A valve is arranged on one side of the discharge port 19 to facilitate controlling the working state of the discharge port 19.
