[0038] The following will be combined with the drawings of the specific embodiments of the utility model to clearly and completely describe the exemplary scheme of the utility model. Unless otherwise defined, the technical terms or scientific terms used in the utility model should be the common meanings understood by people with ordinary skills in the relevant field.

[0039] like Figure 1 and Figure 2 As shown, in the unloading device for aluminum powder silo of this embodiment, the silo 200 is fixed on the frame 100, and a material discharge pipe 300 is connected below the silo 200. The unloading device 400 includes a unloading pipe 410, a first material receiving trough 420, a second material receiving trough 430 and a telescopic cylinder 440. The unloading pipe 410 is connected to the lower end of the material discharge pipe 300 through a flange 450; the first material receiving trough 420 is rotatably arranged on the outer side of the lower left part of the unloading pipe 410 through a first pin shaft 421; the second material receiving trough 430 is rotatably arranged on the outer side of the lower right part of the unloading pipe 410 through a second pin shaft 431, and the left part of the second material receiving trough 430 is cross-built into the first material receiving trough 420, and the first material receiving trough 420 and the second material receiving trough 430 together wrap the lower part of the unloading pipe 410. The telescopic cylinder 440 is fixedly arranged on the frame 100, and the output end of the telescopic cylinder 440 is connected to the first material receiving trough 420, and the first material receiving trough 420 and the second material receiving trough 430 are linked to each other to realize the opening and closing action.

[0040] like Figure 3 and Figure 4 As shown, the first receiving trough 420 includes two first straight panels 423 and a first arc-shaped plate 424 welded between the two first straight panels 423, and the first straight panels 423 are fan-shaped.

[0041] like Figure 3 and Figure 4 As shown, a first gear 422 is welded to the outer side of the first straight plate 423 on the front side, and the axis of the first gear 422 coincides with the axis of the first pin shaft 421 .

[0042] like Figure 4 and Figure 6 As shown, a rubber pad 425 with a gradually changing thickness is installed inside the first curved plate 424, and the thickness of the rubber pad 425 is the smallest at the bottom and the largest at the top, so as to ensure that the first receiving trough 420 and the second receiving trough 430 can rotate and cross smoothly. The rubber pad 425 can be fixed inside the first curved plate 424 by bonding.

[0043] like Figure 3 and Figure 5 As shown, the second receiving trough 430 includes two second straight panels 433 and a second arc-shaped plate 434 welded between the two second straight panels 433 , and the second straight panels 433 are fan-shaped.

[0044] like Figure 3 and Figure 5 As shown, a second gear 432 is welded to the outer side of the second straight plate 433 on the front side, the axis of the second gear 432 coincides with the axis of the second pin shaft 431 , and the first gear 422 and the second gear 432 are meshed with each other.

[0045] like Figure 3-Figure 5 As shown, the radius of the first straight plate 423 is greater than the radius of the second straight plate 433 , and the length of the first curved plate 424 is greater than the length of the second curved plate 434 .

[0046] like Figure 5 As shown, baffles 435 are welded to the outer sides of the two second straight plates 433, and the baffles 435 contact with a straight edge of the first straight plate 423. Further, the width of the baffles 435 is greater than the difference between the lengths of the first curved plate 424 and the second curved plate 434.

[0047] like Figure 1-Figure 3 As shown, one end of the telescopic cylinder 440 is pinned to a first bracket 441, and the first bracket 411 is welded and fixed to the frame 100; the other end of the telescopic cylinder 440 is pinned to a second bracket 442, and the second bracket 442 is welded and fixed to the outer side of the second arc plate 434 of the second material receiving trough 430.

[0048] Furthermore, a reinforcing plate 443 is welded to the outer side surface of the second arc plate 434 , and the second bracket 442 is also welded to the reinforcing plate 443 to improve the connection stability between the second arc plate 434 and the second bracket 442 .

[0049] The telescopic cylinder 440 is connected to an external air source, and the telescopic movement of the telescopic cylinder 440 is controlled by controlling the external air source, and the telescopic stroke of the telescopic cylinder 440 is equal to the rotation stroke of the first material receiving trough 420 and the second material receiving trough 430.

[0050] When the telescopic rod of the telescopic cylinder 440 is extended, the telescopic rod drives the second receiving trough 430 to rotate forward, and drives the first receiving trough 420 to rotate reversely through the first gear 422 and the second gear 432. Since the radius of the first straight plate 423 is greater than the radius of the second straight plate 433, and the length of the first curved plate 424 is greater than the length of the second curved plate 434, a part of the second receiving trough 430 rotates into the first receiving trough 420 to form a cross portion. Figure 1 and Figure 3As shown, after the first receiving trough 420 and the second receiving trough 430 rotate and cross, the top of the baffle 435 exceeds the bottom of the discharge pipe 410 to avoid side leakage.

[0051] In addition, when the first material receiving trough 420 and the second material receiving trough 430 rotate and cross, the rubber pad 425 and the second arc plate 434 fit tightly together, ensuring the sealing between the first arc plate 424 and the second arc plate 434 to avoid leakage from the bottom.

[0052] When the telescopic rod of the telescopic cylinder 440 stops extending, the baffle 435 welded on the second straight plate 433 contacts a straight edge of the first straight plate 423 to ensure the seal between the first straight plate 423 and the second straight plate 433 to avoid side leakage.

[0053] How this application works is:

[0054] The telescopic cylinder 440 is turned on, and the telescopic rod of the telescopic cylinder 440 begins to extend, driving the second material receiving trough 430 to rotate forward, and driving the first material receiving trough 420 to rotate reversely through the first gear 422 and the second gear 432.

[0055] When the telescopic rod of the telescopic cylinder 440 reaches the longest, the first receiving trough 420 and the second receiving trough 430 are crossed and closed, and the telescopic cylinder 440 is closed. At this time, aluminum powder is conveyed into the silo 200, and when the silo 200 is filled with aluminum powder, the conveying of aluminum powder is stopped.

[0056] Then, the receiving vehicle is driven to the bottom of the unloading device 400, and the telescopic cylinder 440 is turned on again. The telescopic rod of the telescopic cylinder 440 begins to shrink, driving the second receiving trough 430 to rotate in the opposite direction, and driving the first receiving trough 420 to rotate in the forward direction through the first gear 422 and the second gear 432. The first receiving trough 420 and the second receiving trough 430 gradually open, and the aluminum powder is unloaded into the receiving vehicle at the same time.

[0057] The coordinated use of the first curved plate 424, the second curved plate 434 and the rubber pad 425, as well as the coordinated use of the first straight plate 423, the second straight plate 433 and the baffle 435, provides good sealing for the intersection of the first receiving trough 420 and the second receiving trough 430, and effectively avoids the problem of aluminum powder leakage from the silo.
