After drying, by deflecting the connecting plate 10 and starting the hydraulic cylinder 3 to deflect the drying box 4, the raw materials inside the drying box 4 are collected.

[0042] The slot two 73 is concentric with the hot air blower 14, and the slot one 72 is located on the outer surface of the slot two 73. The central diameter of the threaded plate 77 gradually decreases from left to right. The surface of the heat conducting column 71 is provided with a communication groove 75, and the communication groove 75 is respectively communicated with the diversion groove 74 and the placement groove 76.

[0045] Embodiment two, on the basis of Embodiment one, please continue to refer to Figure 7, the present invention provides a technical solution: The impact component 79 includes a fixed cover 791.

On the inner wall of the fixed cover 791, a support plate 793 is fixedly connected. The support plate 793 contacts the fixed plate 792. On the right side of the support plate 793, a support rod 798 is fixedly connected. On the right side of the support plate 793, a fixed frame 795 is provided. The support rod 798 penetrates through the middle of the fixed frame 795. One end of the fixed frame 795 away from the support plate 793 is fixedly connected to an arc-shaped plate 796. On the outer surface of the support rod 798, a second spring 799 is arranged. The left side of the second spring 799 is fixedly connected to the support plate 793, and the right side of the second spring 799 is fixedly connected to the fixed frame 795. The support rod 798 penetrates through the arc-shaped plate 796. On the inner wall of the fixed cover 791, a third communication hole 794 is opened. At both the upper and lower ends of the arc-shaped plate 796, a fourth slot 797 is opened. When the arc-shaped plate 796 is blown by hot air, it squeezes the second spring 799 through the fixed frame 795, causing the arc-shaped plate 796 to deflect in the middle of the fixed frame 795 through the support rod 798 and strike the fixed plate 792. When hot air flows in the second slot 73, the hot air blows towards the arc-shaped plate 796.

Among them, under the restriction of the middle of the fixed frame 795, the support rod 798 strikes the fixed plate 792 through the fourth slot 797 opened on the surface of the arc-shaped plate 796, shaking off the raw materials adhered to the surface of the fixed plate 792. At the same time, when the arc-shaped plate 796 shakes, part of the hot air entering from the second slot 73 is discharged from the third communication hole 794 to dry the raw materials.

[0046] Embodiment 3. On the basis of Embodiment 1 and Embodiment 2, please continue to refer to Figures 10-11, the present invention provides a technical solution: the shaking mechanism 8 includes an elastic frame 81, a slot five 82 is formed on the surface of the elastic frame 81, a knocking component 83 is arranged at the top of the elastic frame 81, and the distance from the end of the elastic frame 81 to the center of the heat conduction column 71 is greater than the distance from the bent end of the stirring rod 12 to the center of the heat conduction column 71. The elastic frame 81 is used for the auxiliary drying of raw materials to increase the contact area between the raw materials and hot air. The knocking component 83 includes two elastic plates 831, a fixing rod 832 is fixedly connected between the two elastic plates 831, a deflection ring 833 is arranged at the top of the elastic frame 81, the deflection ring 833 is open, and the fixing rod 832 is rotatably connected to the deflection ring 833 through a rotating shaft at the notch.

When part of the raw materials are driven by the stirring rod 12 above the elastic frame 81, the stirring rod 12 and the elastic frame 81 are disengaged from collision, and the raw materials adhered to the surface of the stirring rod 12 are shaken off. At the same time, the elastic frame 81 can also vibrate to shake off the raw materials on its surface. When there are large lumps of raw materials, the raw materials will accumulate at the connection between the fixing rod 832 and the deflection ring 833. During the rotation of the stirring rod 12, the heavy ball 836 is squeezed, so that the heavy ball 836 pulls the fixing rod 832 to move. After the fixing rod 832 moves, it squeezes the deflection ring 833, causing the deflection ring 833 to deflect. As the stirring rod 12 moves away and the deformation angle of the elastic plate 831 increases, the fixing rod 832 is reset with the assistance of the elastic plate 831, and the deflection ring 833 breaks up the lumped raw materials with the assistance of the knocking block 834.

A fourth slot (797) is provided at both the upper and lower ends of the arc plate (796). When the hot air blows, the arc plate (796) squeezes the second spring (799) through the fixing frame (795), so that the arc plate (796) deflects in the middle of the fixing frame (795) through the support rod (798) and knocks the fixing plate (792).

7. The drying device for biomass materials according to claim 2, characterized in that: The shaking mechanism (8) comprises an elastic frame (81), a groove (82) is provided on the surface of the elastic frame (81), a knocking assembly (83) is provided on the top of the elastic frame (81), and the distance from the end of the elastic frame (81) to the center of the heat-conducting column (71) is greater than the distance from the bent end of the stirring rod (12) to the center of the heat-conducting column (71). The elastic frame (81) is used for auxiliary drying of raw materials and increasing the contact area between the raw materials and the hot air.

8. The drying device for biomass materials according to claim 7, characterized in that: The knocking assembly (83) comprises two elastic plates (831), a fixed rod (832) is fixedly connected between the two elastic plates (831), a deflection ring (833) is arranged on the top of the elastic frame (81), the deflection ring (833) is open, and the notch of the fixed rod (832) is rotatably connected to the deflection ring (833) through a rotating shaft, and a knocking block (834) is rotatably connected to the top of the deflection ring (833) through a rotating shaft, and the knocking block (834) is connected to the elastic frame (81). The fixing rod (832) is in contact with the surface of the force frame (81), and a pull rope (835) is fixedly connected to the outer surface of the fixing rod (832). The pull rope (835) is in contact with the groove wall of the slot five (82). The end of the pull rope (835) away from the fixing rod (832) is fixedly connected to a heavy ball (836).
