Description

Technical Field

[0001] The utility model relates to the field of biomass fuel processing, in particular to an automatic feeding device for biomass fuel processing. Background Art

[0002] An automatic feeding device for biomass fuel processing is a device specially used for biomass fuel processing. Biomass fuel is a renewable energy source made from agricultural and forestry waste (such as straw, sawdust, bagasse, rice bran, etc.), which is less polluting and renewable than fossil fuels. Among them, sawdust after crushing is also a kind of biomass fuel, and the crushed sawdust has less impact on the greenhouse effect when it is processed into fuel and burned.

[0003] Due to the large size of the biomass fuel processing device, an automatic loading device is usually used to transport the wood chips to the inside of the processing device. At present, the surface of the existing loading device is only provided with a conveyor belt, and no limit structure is provided. In addition, when the loading device is running, it will vibrate under the action of the motor. Therefore, when the loading device is transporting high calorific value fuels such as wood chips, the wood chip fuel will fall from both sides of the loading device under the vibration of the loading device, and the operator needs to collect the fallen wood chips later, which makes it impossible for the operator to perform subsequent processing on the transported wood chips and other high calorific value fuels. How to solve these problems has become an urgent problem to be solved by technicians in this field. Utility Model Content

[0010] By adopting the above technical solution, the conveyor belt can support the rotating shaft through the connecting plate. When the conveyor belt is running, the rotating shaft can be driven to rotate through the transmission member. When the knocking plate rotates, the auxiliary plate can be knocked to assist the wood chips to fall.

[0012] Preferably, the end of the transmission shaft away from the transmission member 2 passes through the loading bin and extends to the interior of the loading bin, the outer wall of the transmission shaft is rotatably connected to the inner wall of the loading bin penetrated, and the end of the transmission shaft extending to the interior of the loading bin is fixedly connected to the lifting plate.

[0013] By adopting the above technical solution, when the transmission shaft rotates under the action of the second transmission member, the lifting plate can be driven to rotate.

[0014] Preferably, the bottom of the movable frame contacts the outer wall of the lifting plate, the interior of the movable frame and the interior of the loading bin are both provided with notches, and the top of the hollow plate is an inclined surface.

[0015] By adopting the above technical solution, when the lifting plate rotates, the movable frame can be pushed to slide, and the hollow plate on the inclined surface can assist the movement of wood chips when shaking.

At this time, the wood chips and other high-calorific value fuels accumulated on the top of the hollow plate will be filtered through the hollow plate under the impact force generated by the collision, thereby preventing insufficiently crushed fuel from entering the interior of the processing device, resulting in the defects of loose structure, easy rupture and water absorption in the processed fuel.

The transmission member 2 402 drives the lifting plate 404 to rotate through the transmission shaft 403, so that the movable frame 405 drives the hollow plate 406 to move longitudinally under the action of the eccentric wheel-style lifting plate 404. When the movable frame 405 collides with the support rod 408, the hollow plate 406 will Screening is performed, and the high calorific value fuels such as sawdust that have completed the screening will fall on the top of the conveyor belt 1; when the conveyor belt 1 transports the high calorific value fuels such as sawdust, the transmission member 302 can drive the knocking plate 304 to rotate through the rotating shaft 303, so that the knocking plate 304 knocks the auxiliary plate 3011, so that the high calorific value fuels such as sawdust accumulated on the surface of the conveyor belt 1 are separated from the conveyor belt 1, the rubber baffle 301 and the auxiliary plate 3011 under the force of the knocking plate 304 knocking on the auxiliary plate 3011, and fully fall into the interior of the processing device.
