The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly specifying the number of indicated technical features or their sequential relationship.

[0031] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0032] Reference Figure 1 , 2 As shown in Figure 3, the lower return hopper according to an embodiment of the present invention includes a hopper body 100, a lifting structure 200, and multiple support members 300. The hopper body 100 has a mounting cavity 110 with a lower opening. The lifting structure 200 includes a lifting member 210, which is movably mounted below the hopper body 100. The lifting member 210 can receive plates 201 from the outside and lift them into the mounting cavity 110. Multiple support members 300 are swayably mounted on the hopper body 100 and located on one side of the lifting member 210. At least a portion of the support member 300 is located within the mounting cavity 110, and the support member 300 can rotate between a clearance position and a support position. Figure 3 As shown, in the avoidance position, the lifting member 210 can lift the plate 201 into the mounting cavity 110; as Figure 2 As shown, in the supported position, the support member 300 can support the plate 201 located in the mounting cavity 110.

[0033] By providing a hopper 100, a lifting member 210, and a support member 300 that can rotate between a clearance position and a support position, when multiple drilled plates 201 are sequentially conveyed onto the lifting member 210, the sequential lifting of the lifting member 210, in conjunction with the support member 300 switching back and forth between the clearance position and the support position, allows the multiple drilled plates 201 to be stacked sequentially in the mounting cavity 110 of the hopper 100, thus eliminating the need for manual material receiving and stacking of the plates 201.

[0034] Understandably, multiple supports 300 are pivotally positioned on one side of the lifting member 210 to avoid the lifting member 210 interfering with the rotation of the supports 300.

[0035] Specifically, the lower return hopper is connected to the discharge conveyor line or ejection cylinder of the automatic drilling machine, and the plates 201 after multiple drillings will be sequentially conveyed to the lifting component 210 under the action of the discharge conveyor line or ejection cylinder; such as Figure 2 , 3As shown, when the first plate 201 is conveyed to the lifting member 210, the lifting member 210 moves upward, causing the first plate 201 to move upward and into the mounting cavity 110. During the movement, the support member 300 rotates to a clearance position under the action of external force, thus ensuring that the support member 300 does not obstruct the first plate 201 from entering the mounting cavity 110. When the first plate 201 moves above the support member 300, the support member 300 can rotate to a support position under the action of external force or its own weight, thus supporting the first plate 201 and fixing the first plate 201 in the mounting cavity 110. Inside, the lifting member 210 can also move downwards and leave the mounting cavity 110. After the lifting member 210 leaves the mounting cavity 110, the second plate 201 is conveyed onto the lifting member 210. The lifting member 210 also repeats the above steps, so that the second plate 201 is located above the support member 300. Then the support member 300 supports the bottom of the second plate 201, completing the stacking of the first plate 201 and the second plate 201. When multiple plates 201 need to be recycled, the above steps are also repeated. Multiple plates 201 are stacked in the mounting cavity 110 in the vertical direction, and the support member 300 supports the bottom of the lowest plate 201 among the multiple plates.

[0036] In some embodiments of this utility model,

[0037] like Figure 3 As shown, when the lifting member 210 lifts the plate 201 into the mounting cavity 110, the plate 201 can drive the support member 300 to switch from the supporting position to the avoidance position.

[0038] like Figure 2 As shown, the support member 300 can switch from a clearance position to a support position under its own weight.

[0039] This configuration eliminates the need for a drive unit to connect to the support member 300. The support member 300 can switch back and forth between the avoidance position and the support position simply by its own weight and the pushing action of the plate 201, thus simplifying the structure of the lower return hopper.

[0040] At work, such as Figure 3 As shown, when the lifting member 210 lifts the plate 201 into the mounting cavity 110, the plate 201 can drive the support member 300 to switch from the supporting position to the clearance position, and thus the plate 201 can enter the mounting cavity 110; when the plate 201 moves upward above the support member 300, the support member 300 can switch from the clearance position to the supporting position under its own weight; when the lifting member 210 moves downward away from the mounting cavity 110, the plate 201 moves downward with the lifting member 210, and after moving downward a certain distance, the support member 300 blocks the plate 201 from moving downward with the lifting member 210, and thus the support member 300 supports the plate 201.

[0041] In some embodiments of this utility model, when the lifting member 210 lifts the plate 201 into the mounting cavity 110, the plate 201 can drive the support member 300 to switch from the supporting position to the avoidance position.

[0042] The lower return hopper also includes an elastic element (not shown in the figure). The elastic element is connected to the support 300 and the hopper body 100 respectively. When the support 300 switches to the avoidance position, the elastic element is biased and applies a biasing force to switch the support 300 to the support position.

[0043] By incorporating an elastic element, the support member 300 can automatically switch back to the support position after being moved to the avoidance position, thus facilitating the support of the plate 201.

[0044] In a further embodiment of this utility model, such as Figure 2 , 3 As shown in Figure 4, the side wall of the silo 100 has a through groove 120 extending in the horizontal direction. One end of the support member 300 is rotatably mounted outside the silo 100, and the other end of the support member 300 can be located in the mounting cavity 110 through the through groove 120.

[0045] When the support member 300 is in the support position, the bottom surface of the through groove 120 abuts against the support member 300.

[0046] The support member 300 is configured in such a way that it can be driven to swing upward by the plate 201, ensuring that the plate 201 can enter the mounting cavity 110 without obstructing it, and that the support member 300 can swing downward under its own weight to abut the bottom surface of the through groove 120, thereby ensuring that the support member 300 can support the plate 201.

[0047] In a further embodiment of this utility model, such as Figure 3 As shown, when the support member 300 is in the avoidance position, the other end of the support member 300 can be located in the through groove 120, so that the upward swinging support member 300 can be temporarily placed in the through groove 120 without obstructing the plate 201 from moving into the mounting cavity 110.

[0048] In a further embodiment of this utility model, there are four support members 300, which are arranged in a rectangular array so that the silo body 100 can stack more plates 201.

[0049] In some embodiments of this utility model, such as Figure 1 , 5As shown, the hopper 100 includes two frames 130 spaced apart from each other on the left and right. The space between the two frames 130 is the mounting cavity 110. The lifting member 210 is located between the two frames 130 so that the entire lifting member 210 can move into the mounting cavity 110 along with the plate 201, and move the plate 201 into the mounting cavity 110 more stably.

[0050] In a further embodiment of this utility model, such as Figure 4 As shown, the frame 130 includes a mounting plate 131 and two adjusting plates 132 spaced apart front and rear. The mounting plate 131 has an adjusting elongated hole 1311 extending in the front-rear direction. At least one adjusting plate 132 is fixed to the mounting plate 131 by screws, with the screws located inside the adjusting elongated hole 1311.

[0051] By providing screws and adjusting elongated holes 1311, the distance between the two adjusting plates 132 can be adjusted when the screws are loosened, thereby accommodating plates 201 of different widths.

[0052] It is conceivable that the distance between the two frames 130 can also be adjusted to accommodate boards 201 of different lengths.

[0053] In a further embodiment of this utility model, such as Figure 5 As shown, the lifting structure 200 also includes a cylinder 220, which is mounted on the chamber 100. The telescopic rod 221 of the cylinder 220 is vertically arranged and connected to the lifting component 210.

[0054] The lifting component 210 is driven by cylinder 220 to securely lift plate 201.

[0055] In a further embodiment of this utility model, such as Figure 5 As shown, the lifting structure 200 also includes:

[0056] The guide assembly 230 is used to guide the lifting member 210 to move up and down. The guide assembly 230 includes a slide 231 and a slider 232. The slide 231 is mounted on the chamber 100, and the slider 232 is mounted on the slide 231 in a way that allows it to slide up and down.

[0057] The connecting rod 240 is connected to the telescopic rod 221, the slider 232, and the lifting component 210, respectively.

[0058] By providing a guide component 230, the lifting component 210 can be guided to move up and down, ensuring that multiple plates 201 can be stacked in the mounting cavity 110.

[0059] In a further embodiment of the present invention, the lifting member 210 is fixed to the connecting rod 240 in a way that allows it to move back and forth, so that the lifting member 210 can adjust the position of the lifting plate 201 and improve the applicability of the lifting member 210.
