A dust collecting box is placed at the bottom of the inner side of the furnace body, an ash pushing plate is threadedly sleeved on the outer side of the screw, a slider slidably connected to the inner side of the furnace body is provided on the outer side of the ash pushing plate, an ash baffle located on the outer side of the screw and on the inner side of the slider is fixedly installed on the inner side of the furnace body, and a U-shaped frame located on the inner side of the ash baffle is fixedly installed on both sides of the ash pushing plate.
[0005] Preferably, the inner side of the ash pushing plate is penetrated by a avoidance groove adapted to the ash blocking plate.
[0006] Preferably, a brush is provided on the inner side of the U-shaped frame.
[0007] Preferably, grooves adapted to the ash collecting box are provided on both sides of the inner bottom of the furnace body. Beneficial effects
[0008] 1. The biomass pellet hot air furnace can shield the threaded section through the ash baffle to prevent the ash from accumulating on the outside of the screw. Then, driven by the motor, the ash pusher plate is stably driven to move through the rotation of the screw, so that the ash can be cleaned to the inside of the ash box for collection.
[0009] 2. The biomass pellet hot air furnace can clean the ash attached to the outside of the screw through the brush when the ash pushing plate moves, and the U-shaped frame will not block the cleaned ash, so that the ash falls by itself under the action of gravity.

[0017] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the relevant utility model and are not intended to limit the utility model. It should also be noted that, for ease of description, only the portions relevant to the utility model are shown in the accompanying drawings.
[0018] The drawings in the embodiments of the present invention: different types of section lines in the drawings are not marked according to national standards, nor do they impose any requirements on the materials of the components. Instead, they are used to distinguish the cross-sectional views of the components in the drawings.
[0019] See also Figure 1-5The ash collecting box 7 is placed on the bottom of the inner side of the furnace body 1, and an ash pushing plate 8 is threadedly sleeved on the outer side of the screw 5. The outer side of the ash pushing plate 8 is provided with a slider 9 slidably connected to the inner side of the furnace body 1. An ash baffle 10 is fixedly installed on the inner side of the furnace body 1, which is located on the outer side of the screw 5 and on the inner side of the slider 9. The screw 5 can be shielded and protected by the ash baffle 10 to prevent the ash from falling directly onto the surface of the screw 5, and the ash attached to the outer side of the ash baffle 10 can be automatically cleaned during the movement of the ash pushing plate 8. U-shaped frames 11 located on the inner side of the ash baffle 10 are fixedly installed on both sides of the ash pushing plate 8.
[0020] Among them, the inner side of the dust pushing plate 8 is penetrated by a avoidance groove 12 which is adapted to the dust baffle 10. The avoidance groove 12 can avoid the dust baffle 10 while the dust baffle 10 will not interfere with the movement of the dust pushing plate 8, ensuring that the dust pushing plate 8 can clean the outer surface of the dust baffle 10 during the movement.
[0021] Among them, a brush 13 is provided on the inner side of the U-shaped frame 11, which can be used to clean the furnace ash attached to the threaded section of the screw 5, and the cleaned furnace ash can fall from the inner side of the U-shaped frame 11 to the bottom of the furnace body 1 for collection. At the same time, the U-shaped frame 11 will not interfere with the ash box 7 during movement, ensuring that the ash pushing plate 8 can fit with the ash box 7 during movement, so that the furnace ash accumulated at the bottom of the furnace body 1 can be completely pushed to the inner side of the ash box 7 for collection.
[0022] Among them, grooves 14 adapted to the ash box 7 are provided on both sides of the inner bottom of the furnace body 1. The grooves 14 can limit the ash box 7 while making the inner side surface of the bottom of the ash box 7 lower than the inner side surface of the bottom of the furnace body 1, so that the ash at the bottom of the furnace body 1 can be cleaned to the inner side of the ash box 7 for collection by moving the ash pushing plate 8.
[0023] When cleaning the furnace ash, start the motor 6. The drive of the motor 6 can drive the screw 5 to rotate and at the same time drive the ash pushing plate 8 to move along the axial direction of the screw 5. The movement of the ash pushing plate 8 can clean the furnace ash accumulated on the bottom inner side of the furnace body 1, and the movement of the ash pushing plate 8 can drive the brush 13 on the inner side of the U-shaped frame 11 to move synchronously. At this time, the brush 13 can clean the furnace ash attached to the surface of the screw 5, and as the ash pushing plate 8 continues to move, the furnace ash is gradually pushed to the inner side of the ash box 7 for collection. The content not described in detail in this description belongs to the existing technology known to professional and technical personnel in this field.
