[0030] Reference Figure 1 As shown, this utility model provides a technical solution: a sieve machine support structure, including a base 1, a pad 3 installed on the upper surface of the base 1, a stand 2 detachably installed on the side of the pad 3 away from the base 1, a top frame 4 installed on the side of the stand 2 away from the base 1, a positioning device 5 provided on the surface of the stand 2, and an adjustment device 6 provided on the surface of the stand 2.

[0031] The specific settings and functions of the positioning device 5 and the adjustment device 6 will be described in detail below.

[0032] Reference Figures 1-4 As shown in this embodiment: the positioning device 5 includes two sliders 501. Two grooves are formed on the lower surface of the top frame 4. Both sliders 501 are slidably connected to the surfaces of the grooves on the top frame 4. A connecting rod 502 is fixedly connected to one end of each slider 501 near the base 1. A connecting plate 504 is sleeved on the surface of the connecting rod 502. A positioning rod 505 is fixedly connected to the upper surface of the connecting plate 504. The positioning rod 505 is slidably connected to the inner wall of the top frame 4. By setting the sliders 501, the connecting rod 502 can be connected to the top frame 4, while ensuring that the position of the connecting rod 502 can be adjusted. By setting the positioning rod 505, a positioning effect can be achieved when connecting to the sieving machine. A fixing rod 506 is slidably connected to the inner wall of each slider 501. A second spring 507 is sleeved on the surface of the fixing rod 506. The two ends of the second spring 507 are fixedly connected to the slider 501 and the top frame 4, respectively. By setting the fixing rod 506, the position of the second spring 507 can be restricted, and by setting the second spring 507, the movement of the slider 501 can be restricted.

[0033] A first spring 503 is fitted onto the surface of the connecting rod 502, and both ends of the first spring 503 are fixedly connected to the slider 501 and the connecting plate 504, respectively. By setting the first spring 503, a stable connection between the connecting plate 504 and the slider 501 can be ensured, while preventing the connecting plate 504 from detaching from the connecting rod 502. Arc-shaped plates 508 are fixedly connected to both sides of the base 1. A first screw 509 is threaded into the inner wall of the arc-shaped plate 508. A limiting plate 510 is rotatably connected to the end of the first screw 509 near the top frame 4. The limiting plate 510 has a U-shaped cross-section and fits tightly against the upright 2. By setting the arc-shaped plate 508, the first screw 509 can be connected to the base 1. By setting the limiting plate 510, the position of the upright 2 can be restricted when connecting the upright 2 and the base 1. By setting the first screw 509, the position of the limiting plate 510 can be adjusted.

[0034] Reference Figure 1 and Figure 2 as well as Figure 5 As shown, specifically, the adjustment device 6 includes four adjustment rods 66, all of which are slidably connected to the inner wall of the support frame 2. The ends of the four adjustment rods 66 furthest from the base 1 are fixedly connected to the top frame 4. Adjustment plates 61 are fixedly connected to the sides of each of the four adjustment rods 66. By setting the adjustment rods 66, the distance between the support frame 2 and the top frame 4 can be adjusted. The adjustment plates 61 facilitate the adjustment of the position of the adjustment rods 66. A connecting frame 62 is fixedly connected to the side of the adjustment plate 61 furthest from the adjustment rods 66. The connecting frame 62 fits tightly against the support frame 2, and a control plate 64 is fixedly connected to the inner wall of the connecting frame 62. By setting the connecting frame 62, the adjustment plate 61 can be moved simultaneously. By setting the control plate 64, the movement of the connecting frame 62 can be easily controlled.

[0035] An installation plate 63 is fixedly connected to the inner wall of the support frame 2, and a second screw 65 is threaded into the inner wall of the control plate 64. The second screw 65 is rotatably connected to the installation plate 63. By setting the installation plate 63, the second screw 65 can be installed, and by rotating the second screw 65, the position of the control plate 64 can be adjusted.

[0036] Working principle: When the sieving machine needs to be supported by a sieving machine elevation bracket, firstly, the base 1 is fixed to the installation position. Then, the upright 2 is moved close to the pad 3 on the base 1, and the first screw 509 is rotated to rotate on the inner wall of the arc plate 508 and the surface of the limiting plate 510. This controls the limiting plate 510 to move closer to the upright 2, restricting the position of the upright 2. Then, the upright 2 is connected to the base 1. Next, the sieving machine is moved close to the positioning rod 505 on the top frame 4 to complete the positioning work during the installation of the sieving machine. After partially fixing the sieving machine, the connecting plate 504 is moved to drive the positioning rod 505 to slide on the inner wall of the top frame 4. Continuing to move the connecting plate 504 drives the slider 501 to slide on the surface of the fixed rod 506. The surface slides, and then the sieving machine is fixed. The connecting plate 504 is loosened. Under the action of the second spring 507, the slider 501 slides to its original position on the surface of the fixing rod 506. Under the action of the first spring 503, the connecting plate 504 slides to its original position on the surface of the connecting rod 502, thus completing the installation of the sieving machine. By setting the positioning device 5, when connecting the sieving machine to the upright 2, the positioning rod 505 can be used to position the sieving machine at the same time as installing it onto the upright 2, improving the efficiency of the connection between the sieving machine and the upright 2. At the same time, it can also play a positioning role when connecting the upright 2 and the base 1, so as to avoid the upright 2 from shifting when it is fixed.

[0037] When it is necessary to adjust the distance between the top frame 4 and the upright 2, the second screw 65 is rotated to make it rotate on the inner wall of the control plate 64 and the surface of the mounting plate 63. Thus, the control plate 64 drives the adjusting rod 66 to move through the connecting frame 62 and the adjusting plate 61, thereby adjusting the position of the top frame 4. By setting the adjusting device 6, when using the sieving machine support bracket to support the sieving machine, the height of the sieving machine support bracket can be adjusted according to the actual working needs, thereby avoiding the need to install different uprights 2 according to the usage height and reducing the cost of using the sieving machine support bracket.

[0038] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
