[0016] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. The high-efficiency combustion biomass boiler, through the provided pulverizing mechanism, allows the fuel used for combustion to enter the box body through the feed hopper, and then starts the first motor to rotate the first pulverizing roller. The rotation of the first pulverizing roller will rotate the first pulley, and the first pulley rotates the second pulley through the cooperation of the first belt, thereby rotating the second pulverizing roller and the first gear. Since the first gear is meshed with the second gear, the rotation of the second pulverizing roller will rotate the second gear, thereby rotating the third pulverizing roller. Therefore, the operation of the first motor will rotate the first pulverizing roller, and will also cause the second pulverizing roller and the third pulverizing roller to rotate in opposite directions. After the fuel enters the box body, it is first pulverized by the first pulverizing roller and the inner wall of the box body. The fuel after the first pulverization will continue to fall downward, and the fuel is pulverized by the second pulverizing roller and the third pulverizing roller by rotating in opposite directions, so that the fuel is pulverized more thoroughly, so that the fuel burns more fully, and then the furnace body can fully burn the fuel.

[0017] 2. The high-efficiency combustion biomass boiler, through the set conveying assembly, the crushed fuel will slide into the conveying cylinder through the feed pipe, and the first pulley rotates the third pulley through the cooperation of the second belt, so that the first rotating shaft rotates, and the first rotating shaft rotates the auger rod in the conveying cylinder through the cooperation of the first bevel gear and the second bevel gear. The fuel in the conveying cylinder will be transported upward by the rotation of the auger rod. At the same time, the operation of the heating cylinder will increase the temperature inside the conveying cylinder, thereby drying the trace moisture in the conveyed fuel, so that the fuel can be further fully burned, thereby increasing the combustion efficiency.

[0018] 3. The high-efficiency biomass combustion boiler uses a spreading mechanism to allow the fuel to fall onto the leak plate in the furnace body through the discharge pipe. Then, the second motor is started to rotate the second shaft, and the second shaft drives the striking wheel to rotate. The striking wheel hits the leak plate to move it to the left. When the striking wheel does not contact the leak plate, the leak plate will move to the right due to the tension of the first spring and the elastic force of the second spring. Therefore, the continuous rotation of the striking wheel will cause the leak plate to move back and forth left and right, so that the fuel on the leak plate can move back and forth left and right, so that the fuel can be scattered in the furnace body, which can maximize energy safety, optimize combustion efficiency, and reduce environmental emissions.

[0019] 4. This high-efficiency biomass boiler starts two fans when the furnace burns the fuel through the blower mechanism. The two fans will draw the outside air into the connection box, and then the metal air pipe will blow the air into the furnace. The air contains oxygen. Due to the increase of oxygen, the fuel and air can be mixed more fully, the combustion speed can be accelerated, the thermal efficiency can be improved, and the heat loss caused by incomplete combustion can be reduced, thereby improving energy utilization.

A rectangular frame 82 is fixedly connected to the left side of the connecting plate 81, a connecting box 83 is fixedly connected inside the rectangular frame 82, a fan 84 is fixedly connected to the inner wall of the connecting box 83 symmetrically up and down, and a metal air pipe 85 is fixedly connected to the right side of the connecting box 83.

[0038] Furthermore, In actual operation, when the device is used, the fuel used for combustion is fed into the box body 612 through the feed hopper 613, and then the first motor 6111 is started to rotate the first crushing roller 614. The rotation of the first crushing roller 614 causes the first pulley 6112 to rotate. The first pulley 6112 rotates the second pulley 6113 through the cooperation of the first belt 6114, thereby rotating the second crushing roller 615 and the first gear 617. Since the first gear 617 is meshed with the second gear 618, the rotation of the second crushing roller 615 causes the second gear 618 to rotate. The first motor 6111 rotates the first crushing roller 614, and the second crushing roller 615 and the third crushing roller 616 rotate in opposite directions. After the fuel enters the box body 612, it is first crushed by the first crushing roller 614 and the inner wall of the box body 612.

The striking wheel 712 strikes the leak plate 74 to move it to the left. When the striking wheel 712 does not contact the leak plate 74, the leak plate 74 moves to the right due to the tension of the first spring 78 and the elastic force of the second spring 79. Therefore, the continuous rotation of the striking wheel 712 causes the leak plate 74 to reciprocate left and right, so that the fuel on the leak plate 74 can be reciprocated left and right, so that the fuel can be scattered in the furnace body 4, which can maximize energy safety, optimize combustion efficiency, and reduce environmental emissions. When the furnace body 4 burns the fuel, two fans 84 are started. The operation of the two fans 84 will draw the outside air into the connecting box 83, and then the metal air pipe 85 will blow the air into the furnace body 4. The air contains oxygen. Due to the increase of oxygen, the fuel and air can be mixed more fully, the combustion speed can be accelerated, the thermal efficiency can be improved, and the heat loss caused by incomplete combustion can be reduced, thereby improving the energy utilization rate.
