The two second gears 8 are respectively fixedly installed on the upper ends of the two spiral rods 6. The two second gears 8 are both meshed and connected with the first gear 7.

[0027] Furthermore, the first motor 9 drives the first gear 7 to rotate, so that the two second gears 8 drive the two screw rods 6 to rotate, loosening the added combustion particle raw materials to prevent the combustion particle raw materials from being excessively accumulated, affecting the subsequent heating and drying effect of the materials, accelerating the drying speed, and thus improving the drying efficiency of the device.

[0028] Furthermore, a hot air blower 10 is placed on the right side of the work frame 1. The hot air blower 10 is a prior art and will not be described in detail here. A hot air duct 11 is fixedly installed at the output end of the hot air blower 10, and the upper end of the hot air duct 11 extends to the inner upper end of the drying chamber 2.

[0029] Furthermore, a connecting pipe 12 is fixedly installed on the hot air duct 11, and the connecting pipe 12 is communicated with the interior of the hot air duct 11. The end of the connecting pipe 12 away from the hot air duct 11 extends to the interior of the drying bin 2. The connecting pipe 12 is located at the lower end of the interior of the drying bin 2. A drying pipe 13 is fixedly installed on the end of the connecting pipe 12 away from the hot air duct 11, and protective canopies 14 are fixedly installed on both upper ends of the drying pipe 13.

[0030] Furthermore, hot air is allowed to enter the interior of the drying pipe 13 through the connecting pipe 12, and the remaining materials that may accumulate and adhere are heated from both the inside and the outside, thereby further accelerating the drying speed of the materials and improving the working efficiency of the device.

[0033] Working principle: When using this device, the biomass burning and burning particle raw materials that need to be dried can be added into the interior of the drying bin 2 through the feeding pipe 3, and the first motor 9 is started while the biomass burning and burning particle raw materials are added into the drying bin 2, so that the output end of the first motor 9 rotates, driving the first gear 7 to rotate, thereby causing the two second gears 8 meshing with the first gear 7 to rotate, and the rotation of the two second gears 8 drives the two screw rods 6 fixedly connected to the two second gears 8 to rotate. After the biomass burning and burning particle raw materials enter the bottom of the drying bin 2, the biomass burning and burning particle raw materials are close to the two screw rods 6 under the action of the two screw rods 6. The biomass burning and burning particle raw materials move upward along the two screw rods 6 to prevent the biomass burning and burning particle raw materials from accumulating too much and affecting the subsequent addition After the heat is added, the hot air blower 10 is started, and the hot air blower 10 blows the hot air into the interior of the drying bin 2 through the hot air duct 11, and then the two second motors 4 are started, so that the two second motors 4 drive the two fans 15 to rotate, thereby accelerating the flow of hot air. When the hot air passes through the hot air duct 11, part of the hot air will enter the interior of the drying duct 13 along the connecting pipe 12, thereby increasing the temperature of the drying duct 13, and then enter the interior of the drying bin 2 through the two openings on the drying duct 13. The increased temperature of the drying duct 13 will dry and heat the biomass combustion particle raw materials near the drying duct 13, thereby improving the drying efficiency, and the two protective canopies 14 prevent the biomass combustion particle raw materials from falling into the drying duct 13 when they are added to the interior of the drying bin 2, thereby clogging the drying duct 13.
