[0039] Embodiment 1

[0040] Please refer to Figures 1-4 , this embodiment provides a gray line lofting device to improve the working efficiency of lofting.

[0041] In this embodiment, the gray line lofting device includes a gray bin 10, traveling wheels 20 and a handle 30. Among them, the bottom of the gray bin 10 is connected and communicated with a feeding cylinder 11. The outer end of the feeding cylinder 11 is provided with a discharge port 12. The outer wall of the feeding cylinder 11 is connected with a handle 30. Inside the feeding cylinder 11, there is a spiral feeding roller 14 that rotates synchronously with the traveling wheels 20. An impact rod 23 is elastically connected to the traveling wheels 20. On the side wall of the gray bin 10 facing the traveling wheels 20, there is a guiding plate 15 with an increasing height. The guiding plate 15 is arranged on the rotation path of the impact rod 23. On the side wall of the gray bin 10 at the higher end of the guiding plate 15, there is a backing plate 16 that can contact the impact rod 23.

[0042] In this embodiment, the traveling wheels 20 drive the spiral feeding roller 14 to rotate synchronously, and can convey the lime powder in the gray bin 10 to the discharge port 12 and flow out. When the impact rod 23 rotates with the traveling wheels 20, it will be continuously squeezed by the guiding plate 15 and impact the backing plate 16 after leaving the guiding plate 15, which can generate an impact on the lime powder in the gray bin 10 and avoid blockage of the gray bin.

[0043] In this embodiment, the gray bin 10 is integrally constructed as a sector arranged coaxially with the traveling wheels 20. On the side wall of the gray bin 10 away from the traveling wheels 20, a feeding port is opened, and a sealing cover 17 is screwed on the feeding port. The feeding cylinder 11 is integrally constructed as a cylindrical shape arranged coaxially with the gray bin 10. The feeding cylinder 11 and the traveling wheels 20 are arranged coaxially. On the outer wall of the feeding cylinder 11, there is an insertion pipe 13 for inserting the handle 30. The insertion pipe 13 is arranged along the radial direction of the feeding cylinder 11. The handle 30 is arranged outside the bin 10. The discharge port 12 is arranged on the side opposite to the gray bin 10. The gray bin 10 is arranged directly above the feeding cylinder 11, and the discharge port 12 is arranged directly below the feeding cylinder 11. The spiral feeding roller 14 is rotatably arranged inside the feeding cylinder 11 and is arranged coaxially with the feeding cylinder 11. When the spiral feeding roller 14 rotates, it can convey the lime powder inside the feeding cylinder 11 towards the discharge port 12.

[0044] As an example, the gray bin 10, the feeding cylinder 11, the discharge port 12 and the insertion pipe 13 are of an integrally formed structure.

[0045] In addition, the guiding plate 15 is integrally configured as an arc-shaped plate coaxially arranged with the ash bin 10. Along the rotation direction of the traveling wheels 20 during travel, the height of the guiding plate 15 gradually increases, and the higher end of the guiding plate 15 is a steep surface. A backing plate 16 is integrally formed on this steep surface. There is a drop between the backing plate 16 and the higher end of the guiding plate 15, so that the impact rod 23 can impact the backing plate 16 after being released.

[0046] It should be noted that there is a gap between the ash bin 10 and the traveling wheels 20. The impact rod 23 extends into this gap and can pass through this gap smoothly. Both the guiding plate 15 and the backing plate 16 are arranged inside this gap. The guiding plate 15 is used to instantaneously release the impact rod 23 after compression, and the backing plate 16 is used to receive the impact of the impact rod 23.

[0047] In this embodiment, the traveling wheels 20 are integrally configured as a cylindrical shape with one end open. A wheel shaft 21 is fixedly connected to the axis of the traveling wheels 20, and the wheel shaft 21 is configured as a polygon along the cross-section. The shaft hole of the spiral feeding roller 14 is also polygonal and can be adaptively inserted with the wheel shaft 21, so that it rotates synchronously with the traveling wheels 20. A mounting cylinder 24 is fixedly connected to the side wall of the traveling wheels 20 facing away from the ash bin 10. The axis of the mounting cylinder 24 is parallel to the axis of the traveling wheels 20, and the mounting cylinder 24 and the wheel shaft 21 are arranged eccentrically. A limiting groove 26 is opened on the side wall of the mounting cylinder 24. The limiting groove 26 extends along the axial direction of the mounting cylinder 24. The impact rod 23 is inserted into the mounting cylinder 24. The impact rod 23 is arranged parallel to the axis of the traveling wheels 20. A compression spring 25 is provided between the inner end of the impact rod 23 and the bottom of the mounting cylinder 24. At the same time, a limiting plate 27 is fixedly connected to the side wall of the impact rod 23. The limiting plate 27 is slidably clamped inside the limiting groove 26. The sliding clamping cooperation between the limiting plate 27 and the limiting groove 26 slidably limits the impact rod 23 inside the mounting cylinder 24. The elastic thrust of the compression spring 25 makes the outer end of the impact rod 23 extend into the gap between the ash bin 10 and the traveling wheels 20.

[0048] It should be noted that the ash bin 10 is inside the traveling wheels 20 as a whole. The wheel shaft 21 of the traveling wheels 20 passes through the spiral feeding roller 14 and extends out from the outer end face of the feeding cylinder 11, and is locked by a positioning nut 22, thereby connecting the ash bin 10 and the traveling wheels 20 into one body.

[0049] During use, the operating handle 30 pushes the traveling wheels 20 to travel along the set path. Driven by the traveling wheels 20, the spiral feeding roller 14 rotates inside the feeding cylinder 11, and can convey the lime powder inside the feeding cylinder 11 to the discharge port 12 for flowing out, so as to form a lime line on the ground. During the traveling process, the impact rod 23 rotates synchronously with the traveling wheels 20. When the impact rod 23 rotates to contact the guide plate 15, it will continuously retract into the mounting cylinder 24 under the extrusion of the guide plate 15. When the impact rod 23 passes through the highest end of the guide plate 15, it will instantly extend again due to the loss of extrusion restriction and impact the backing plate 16. The impact will generate an impact on the lime powder inside the ash bin 10, causing the lime powder inside the ash bin 10 to fall into the feeding cylinder 11 under the action of gravity, preventing the ash bin 10 from being blocked.

[0050] Although the embodiments of the present application have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present application. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present application.
