[0028] Embodiment 1

[0029] like Figure 1-Figure 4 As shown, the utility model proposes a double-helix structure vacuum spraying equipment, including a spray box 3, a power component and a two-way knocking component. The top of the spray box 3 is connected to a feed hopper 1, and the bottom is connected to a discharge pipe 2. Two groups of spiral dragons 4 are symmetrically arranged on the inner side. The power component is arranged in the spray box 3 on one side of the spiral dragon 4, and drives the two groups of spiral dragons 4 to rotate synchronously at the same time. The two-way knocking component is arranged at the bottom of the spray box 3, and cooperates with the power component to knock on the discharge pipe 2 in both directions.

[0030] like Figure 2 As shown, the power assembly includes a driving motor 5, a rotating rod 6, a worm segment 7 and a worm wheel 8. The driving motor 5 is installed on the top of the outer side of the spray box 3, and its output end passes through the spray box 3 and is connected to the rotating rod 6; two groups of worm segments 7 are symmetrically arranged on the rotating rod 6, and one side of the two groups of worm segments 7 is meshed with a worm wheel 8, and the two groups of worm wheels 8 are correspondingly installed on the central axis of the spiral dragon 4.

[0031] The driving motor 5 drives the rotating rod 6 to rotate, and the rotating rod 6 meshes with the worm wheel 8 through the worm segment 7. The meshing force drives the two groups of spiral dragons 4 to rotate synchronously.

[0032] Embodiment 2

[0033] like Figure 1-Figure 4 As shown, the utility model proposes a double-helix structure vacuum spraying equipment. Based on the above embodiment, this embodiment also records in detail the specific components of the two-way knocking assembly and the connection method between the two-way knocking assembly and the spray box 3.

[0034] like Figure 3 and Figure 4 As shown, the bidirectional knocking assembly includes a rotating shaft 9, a movable frame 11, a guide column 13 and a limit piece. The rotating shaft 9 is installed at the bottom end of one group of spiral dragons 4, and its bottom end passes through the spray box 3 and is connected to a turntable 10. A movable frame 11 is arranged below the turntable 10, and a through groove 14 is opened on the movable frame 11. A guide column 13 is arranged at an eccentric position of the lower end surface of the turntable 10, and the bottom end of the guide column 13 passes through the movable frame 11 through the through groove 14. A limit piece for limiting its movement trajectory is slidingly arranged in the middle of the movable frame 11.

[0035] like Figure 4 As shown, the movable frame 11 includes a vertical section 1101, a middle vertical section 1102 and two groups of horizontal sections 1103. The middle vertical section 1102 is cross-arranged in the middle of the vertical section 1101, and horizontal sections 1103 are arranged at both ends of the side of the vertical section 1101. The vertical section 1101, the middle vertical section 1102 and the two groups of horizontal sections 1103 are integrally formed.

[0036] The through slot 14 is formed on the vertical section 1102 ; and the two knocking bumps 12 are disposed on the inner side of one end of the horizontal section 1103 .

[0037] Furthermore, the guide pillar 13 is driven to move along a circular trajectory by the rotation of the turntable 10 . During the movement, the side wall of the guide pillar 13 pushes the groove wall of the through groove 14 , thereby driving the moving frame 11 to move.

[0038] like Figure 4 As shown, the limiting member includes a limiting frame 15 and a limiting sleeve 16. The limiting frame 15 is arranged at the bottom of the spray box 3 in an enclosing structure, and passes through two groups of horizontal sections 1103 of the movable frame 11. The opposite sides of the two groups of horizontal sections 1103 are connected with the limiting sleeve 16 located on the outside of the limiting frame 15.

[0039] In summary, when the utility model is in use, the spray material is injected into the spray box 3 through the feed pipe, and the drive motor 5 is started. The drive motor 5 drives the rotating rod 6 to rotate. During the rotation of the rotating rod 6, it drives the worm section 7 to rotate synchronously. When the worm section 7 rotates, it engages with the worm wheel 8. The meshing force drives the two groups of spiral dragons 4 to rotate to transport the material. At the same time, the spiral dragon 4 drives the rotating shaft 9 to rotate, and the rotating shaft 9 drives the guide column 13 to perform circular motion through the turntable 10. During the circular motion, the side wall of the guide column 13 squeezes the groove wall of the through groove 14 on the vertical section 1102, thereby pushing the movable frame 11 to reciprocate on the limit frame 15. During the reciprocating movement, the knocking protrusions 12 at its end continuously impact the two sides of the discharge pipe 2, thereby reducing the probability of blockage of the discharge pipe 2.

[0040] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
