Then, the two half leaves are fixed to the chain unit 241 by bolts and nuts, so that the radial end faces of the two half leaves are tightly fitted, and the two half leaves are tightly fitted along the axial direction of the blade 3 (which is also the extension direction of the chain 24) through the limiting structure.

[0072] See also Figure 7 and Figure 8 In this embodiment, the sprocket mechanism further includes a driven sprocket 22 shaft and a bearing seat 26. A tensioning mechanism 6 is provided at the driven sprocket 22. The tensioning mechanism 6 includes a sliding plate 62 and an elastic member that generates a force on the sliding plate 62 to keep it away from the chain 24. The bearing seat 26 is fixed on the sliding plate 62.

[0077] The working principle of the powder material pipe chain lifting and conveying device of the first embodiment of the utility model is: Figure 1The driving assembly drives the driving sprocket 21 to rotate counterclockwise, so that the chain 24 in the lower channel 112 rises and the chain 24 in the upper channel 111 falls, and the powder is added to the lower channel 112 through the powder inlet 4. Since the blades 3 on the chain 24 at the discharge port of the powder inlet 4 move horizontally to the right, the powder will hardly enter the square shell on the left side of the separation inlet. After the powder enters the lower channel 112, it moves horizontally to the right, vertically upward, and horizontally to the right with the blades 3 of the chain 24 in the lower channel 112. When it reaches the square shell where the driving sprocket 21 is located, the powder falls through the powder outlet 5 under the action of gravity. Figure 7 and Figure 8 During the movement of the chain 24, the compression spring 63 always exerts a leftward force on the driven sprocket 22. When the chain 24 is tight, the driven sprocket 22 will be pulled to the right. At this time, the compression spring 63 is further compressed so that the driven sprocket 22 will not be excessively moved to the right. When the chain 24 is loose, the compression spring 63 moves the driven sprocket 22 to the left so that the chain 24 will not be too loose. The compression degree of the compression spring 63 can also be actively adjusted to make the initial tension of the chain 24 appropriate.

[0078] The beneficial effects of the powder material pipe chain lifting and conveying device of the first embodiment of the utility model are as follows: the sprocket wheel and the chain 24 of the chain transmission mechanism 2 are arranged in the conveying channel 11 of the housing 1, so as to reduce dust during the conveying process; the chain 24 is provided with blades 3, the blades 3 are perpendicular to the extension direction of the chain 24, the blades 3 are adapted to the conveying channel 11, and there is at least one chain unit 241 between adjacent blades 3, and the powder material is conveyed by the blades 3, with high transmission efficiency and good continuity; the powder material is completely conveyed in the housing 1 (except for the powder material inlet 4 and The powder outlet 5 is outside), which effectively reduces dust; the blade 3 is assembled from two halves by a bolt and nut assembly, and the bolt and nut simultaneously fix the blade 3 and the chain unit 241 of the chain 24; the blade 3 is circular, and the lower channel 112 is a circular tube; there is a gap between the blade 3 and the lower channel 112; the discharge port of the powder inlet 4 is connected to the lower channel 112, and the upper channel 111 passes through the powder inlet 4, and the outer wall of the upper channel 111 can reduce dust; a tensioning mechanism 6 is provided to ensure that the tightness of the chain 24 is appropriate.
