Abstract
Description
Technical Field
[0001] This utility model relates to the field of screen support technology, specifically a screen support for testing the mud content of fine aggregates. Background Technology
[0002] For the fine aggregate mud content test, the washing liquid must be sieved through two sieves, 1.18mm and 0.075mm. During the operation, the upper suspension must be poured into the sieve after tilting the washing tank. Currently, there are no suitable dedicated supports on the market. Testers often place the sieve directly on the bottom of the pool or on other supports, which can cause poor sieving of the washing liquid or instability of the sieve supported by other objects, resulting in reduced test efficiency, data deviation, or even test failure. Therefore, there is an urgent need to develop a suitable support to ensure standardized test procedures and improve testing efficiency and data quality. Utility Model Content
[0003] To address the aforementioned technical problems, this utility model provides a sieve support for testing the mud content of fine aggregates. It features detachability, compact sieve design, easy storage, low and stable frame, and ease of use, thus better meeting experimental needs in a more targeted and targeted manner.
[0004] To achieve its technical objectives, this utility model adopts the following technical solution:
[0005] A sieve support for testing the mud content of fine aggregates includes two support frames and two sieve clamps. Each support frame includes a middle plate and columns installed at both ends of the middle plate. The middle plate has a vertical mounting slot in the middle. The two support frames are cross-locked through the opposing mounting slots to form an X-shaped support body. The sieve clamps are located at one end of the middle plate and are sleeved on the side of the middle plate near the sieve body. The sieve clamps are used to restrict the position of the sieve body.
[0006] Preferably, the column and the intermediate plate are perpendicular to each other.
[0007] Preferably, the screen tightener includes a screen tightener body, the screen tightener body is U-shaped and provided with a U-shaped mounting groove adapted to the intermediate plate, and the screen tightener is semi-circularly fitted around the side of the intermediate plate near the screen body through the U-shaped mounting groove.
[0008] More preferably, the side wall of the screen tightener body is provided with screw holes.
[0009] More preferably, the screen tightener further includes a screw that is adapted to the screw hole.
[0010] The beneficial effects of this utility model are as follows:
[0011] This utility model adopts an X-shaped structure design with two cross-interlocking support frames and a sieve clamping device to form a stable support system, which enhances the overall load-bearing capacity of the support and can effectively prevent the sieve body from shaking and shifting during the test. At the same time, the installation bayonet setting enables quick assembly and disassembly of the support body, which is convenient for storage and transportation and saves laboratory space.

[0018] In the description of this utility model, it should be noted that the terms "upper / lower", "front / rear", "inner / outer", "top / bottom", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0019] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within the components of a compatible model. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Furthermore, unless otherwise specified, all components used in this application are commercially available components, and the connection between different components can be achieved through conventional technical means.
[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.
[0021] A sieve support for testing the mud content of fine aggregates, such as Figures 1-4 As shown, it includes two support frames 1 and two screen clamps 2. The support frame 1 includes a middle plate 7 and columns 8 installed at both ends of the middle plate 7. The middle plate 7 has a vertical mounting slot 3 in the middle. The two support frames 1 are cross-locked through the opposite mounting slots 3 to form an X-shaped support body. The screen clamp 2 is set at one end of the middle plate 7 and sleeved on the side of the middle plate 7 near the screen body 9. The screen clamp 2 is used to restrict the position of the screen body 9.
[0022] Preferably, the column 8 and the intermediate plate 7 are perpendicular to each other.
[0023] As a preferred option, such as Figure 2 and Figure 3 As shown, the screen tightening device 2 includes a screen tightening device body. The screen tightening device body is U-shaped and has a U-shaped mounting groove 6 that is adapted to the intermediate plate 7. The screen tightening device 2 is semi-encircled by the U-shaped mounting groove 6 on the side of the intermediate plate 7 near the screen body 9. It should be noted that semi-encircling means that the side of the intermediate plate 7 away from the screen body 9 is not covered at this time, but the other three sides of the intermediate plate 7 are in the U-shaped mounting groove 6.
[0024] As a preferred embodiment, a screw hole 4 is provided on the side wall of the screen tightening device body.
[0025] As a preferred embodiment, the screen tightener 2 also includes a screw 5 that is adapted to the screw hole 4. The screw 5 and the screw hole 4 cooperate with each other to fix the position of the screen tightener 2, thereby clamping the screen body 9.
[0026] The operation method of this utility model is as follows:
[0027] Reverse the two support frames 1 so that the mounting slots 3 on the middle plate 7 face each other, and fasten the two support frames 1 together to form an X-shaped support body; lay the support body flat, place the screen body 9 on the support body, and install the screen clamp 2 on one end of the middle plate 7 of the support frame 1 so that the middle plate 7 is placed in the U-shaped mounting groove 6. At this time, the side of the middle plate 7 away from the screen body 9 is not covered by the screen clamp 2; move the screen clamp 2 so that the screen clamp 2 presses against the side wall of the screen body 9, and then tighten the screw 5 to fix the screen clamp 2; after use, disassemble and store the parts.
[0028] Although the embodiments of this utility model have been described in the specification, these embodiments are merely illustrative and should not limit the scope of protection of this utility model. Various omissions, substitutions, and modifications made without departing from the spirit of this utility model should be included within the scope of protection of this utility model.
