[0022] The stirring grid 400 comprises a horizontal grid 410 and a plurality of vertical grids 420, each of the vertical grids 420 is parallel to each other, the horizontal grid 410 is fixedly connected with each of the vertical grids 420, the horizontal grid 410 is fixedly connected with the second sub-shaft 320, and the horizontal grid 410 is parallel to the bottom surface of the tray body 110.
[0023] The present application relates to a powder sintering stirrer, which receives the sintering powder raw material to be mixed through the material receiving tray 100, and the material receiving tray 100 can be directly placed in the inner cavity of the heating machine provided with a preset temperature. The part of the rotating shaft 200 protruding from the bottom of the material receiving tray 100 can be powered through a steel belt, which solves the disadvantage that the traditional stirrer cannot work at a preset temperature. The stirring support 300 drives the stirring grid 400 to stir the sintering powder raw material through the first sub-shaft 310 and the second sub-shaft 320. The stirring support 300 is connected with the rotating shaft 200, can transmit stirring torque, and realizes uniform stirring of the sintering powder raw material. It is worth mentioning that the stirring grid 400 comprises a horizontal grid 410 and a plurality of vertical grids 420, each of the vertical grids 420 is parallel to each other, the spacing between each of the vertical grids 420 can be the same, through the gap between the vertical grids 420, the sintering powder raw material with a small diameter required in the composite technical index can be filtered, and the sintering powder raw material with a large diameter can be rubbed and disassembled, thereby improving the uniformity of the raw material.
[0024] As Figure 2As shown, in an embodiment of the present application, the powder sintering stirrer further comprises a connecting ring 510. An inner wall of the connecting ring 510 is provided with a threaded groove 511. A central axis of the threaded groove 511 coincides with a central axis of the connecting ring 510. A guide line of the threaded groove 511 is between a top surface of the connecting ring 510 and a bottom surface of the connecting ring 510.
[0025] Specifically, the connecting ring 510 is arranged between the rotating shaft 200 and the stirring support 300, and is used to transmit the rotating torque of the rotating shaft 200.
[0026] The inner wall of the connecting ring 510 is provided with the threaded groove 511. In fact, the threaded groove 511 can be used as a guide groove device for changing the distance between the bottom end of the vertical gate 420 and the bottom surface of the inner cavity of the material receiving tray 100.
[0027] In an embodiment of the present application, the rotating shaft 200 is threadedly connected with a slide rod 520. An outer peripheral surface of a first preset part 521 of the slide rod 520 is provided with threads. An outer peripheral surface of a second preset part 522 of the slide rod 520 is smooth. The first preset part 521 of the slide rod 520 is threadedly connected with the rotating shaft 200.
[0028] Specifically, the rotating shaft 200 is connected with the slide rod 520, and the slide rod 520 can be arranged in the inner cavity of the threaded groove 511. The slide rod 520 can slide in the threaded groove 511 and will not be separated from the threaded groove 511, because the guide line of the threaded groove 511 is between the top surface of the connecting ring 510 and the bottom surface of the connecting ring 510. When the slide rod 520 has a tendency to be separated from the end of the threaded groove 511, the slide rod 520 will be hindered by the top of the connecting ring 510 and the bottom of the connecting ring 510.
[0029] Through the relative sliding between the slide rod 520 and the threaded groove 511, the height of the connecting ring 510 in the height direction from the bottom surface of the tray body 110 can be changed, so as to change the distance between the bottom end of the vertical gate 420 and the bottom surface of the inner cavity of the material receiving tray 100.
[0030] In an embodiment of the present application, the central axis of the slide rod 520 is perpendicular to the central axis of the rotating shaft 200.
[0031] Specifically, through the position setting of the central axes of the slide rod 520 and the rotating shaft 200, the quick assembly of the slide rod 520 can be realized in the working state of the connecting ring 510 sleeved on the rotating shaft 200.
[0032] In an embodiment of the present application, the connecting ring 510 is provided with a through hole 512. The through hole 512 is in communication with the threaded groove 511. The first preset part 521 of the slide rod 520 is threadedly connected with the rotating shaft 200 through the through hole 512. The second preset part 522 of the slide rod 520 is arranged inside the threaded groove 511.
[0033] Specifically, the first preset part 521 of the slide rod 520 is arranged close to the through hole 512. The second preset part 522 of the slide rod 520 is arranged away from the through hole 512. Through the through hole 512 of the connecting ring 510, the first preset part 521 of the slide rod 520 sequentially extends into the connecting ring 510 and the threaded hole of the rotating shaft 200.
[0034] The top end of the second preset part 522 of the slide rod 520 is provided with an internal hexagonal hole, and the threaded connection of the first preset part 521 of the slide rod 520 and the threaded hole of the rotating shaft 200 can be realized through a hexagonal wrench.
[0035] The first preset part 521 of the slide rod 520 extends into the threaded hole of the rotating shaft 200, at this time, the second preset part 522 of the slide rod 520 can be attached to the groove surface of the threaded groove 511 of the connecting ring 510. Further, the rapid assembly of the slide rod 520 is realized.
[0036] As shown in the figure, Figure 1 In an embodiment of the present application, the top end of the rotating shaft 200 is provided with a limiting sheet 210. The geometric center of the limiting sheet 210 is arranged above the central axis of the rotating shaft 200. The bottom of the limiting sheet 210 is fixedly connected with the top of the rotating shaft 200. The connecting ring 510 is sleeved on the outer peripheral surface of the rotating shaft 200.
[0037] Specifically, the limiting sheet 210 is arranged at the top end of the rotating shaft 200. The limiting sheet 210 and the connecting ring 510 can leave an installation gap. This installation gap can be used to clamp the return spring, and further realize the resetting of the connecting ring 510 in the height direction.
[0038] In an embodiment of the present application, the limiting sheet 210 and the connecting ring 510 are provided with a reset spring 220. The reset spring 220 is sleeved on the outer peripheral surface of the rotating shaft 200. One end of the reset spring 220 abuts against the bottom surface of the limiting sheet 210. The other end of the reset spring 220 abuts against the top surface of the connecting ring 510.
[0039] As shown in the figure, Figure 1 In an embodiment of the present application, the outer peripheral surface of the connecting ring 510 is fixedly connected with the first sub-rod 310.
[0040] Specifically, the bottom end of the vertical grid 420 and the bottom surface of the inner cavity of the material receiving dish 100 can be in contact with each other.
[0041] In this working state, the slide bar 520 abuts against the top of the threaded groove 511.
[0042] There may also be a gap between the bottom of the vertical grid 420 and the bottom surface of the inner cavity of the receiving dish 100.
[0043] In this working state, the slide bar 520 abuts against the bottom end of the threaded groove 511 or the middle part of the threaded groove 511.
[0044] like Figure 1 As shown, in one embodiment of this application, a slope 600 is provided on the bottom surface of the inner cavity of the dish body 110. Both ends of the slope 600 are attached to the bottom surface of the inner cavity of the dish body 110. The height of the middle part of the slope 600 is greater than the height of the bottom surface of the inner cavity of the dish body 110.
[0045] Specifically, the height of the middle part of the slope 600 can raise the height of the bottom end of the vertical grid 420, thereby enabling the rapid dispersion of large-volume powder sintered agglomerates.
[0046] More specifically, the angle between the slope surface of the slope 600 and the working surface formed by multiple vertical grids 420 will change, which can greatly increase the stress on the large powder sintering agglomerate.
[0047] It is worth mentioning that the spacing between the multiple vertical grids 420 can be adapted according to process requirements. This allows for control of the uniformity of raw material mixing based on process requirements.
[0048] In one embodiment of this application, the middle portion of the slope 600 is connected to both ends of the slope 600. The middle portion of the slope 600 is a smooth curved surface. The angle between each vertical grid 420 and the bottom surface of the plate body 110 is greater than 30 degrees.
[0049] The technical features of the above embodiments can be combined arbitrarily, and the execution order of the method steps is not restricted. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
[0050] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this application should be determined by the appended claims.
