Abstract
Description
Technical Field
[0001] This utility model relates to the field of raw material testing in construction engineering, and in particular to a test sieve for preventing material jamming. Background Technology
[0002] Coarse aggregate particle size analysis is a crucial step in assessing and ensuring the quality of roads, buildings, and other engineering projects. Traditional particle size analysis primarily relies on sieving using test sieves to determine the particle distribution of coarse aggregates. However, this process presents several technical challenges and limitations: coarse aggregate particles are typically irregularly shaped, which can cause some particles to become stuck in the sieve openings during passage, making them difficult to remove. This irregularity not only increases the difficulty of sieving but can also lead to sieve damage and aggregate loss, thus affecting the accuracy of the data. In traditional sieving processes, the aperture and shape of the test sieve directly influence the passage of coarse aggregates. Forcibly removing coarse aggregates stuck in the sieve openings may damage the openings, and damaging the aggregates can result in inaccurate data, ultimately affecting the final analytical results. Summary of the Invention
[0003] The purpose of this invention is to provide an anti-jamming test sieve, addressing the problem that in the process of screening aggregate particles using conventional pilot-scale test sieves in the background technology, some coarse aggregates are easily stuck in the sieve holes. Forcibly removing the coarse aggregates stuck in the sieve holes can easily damage the sieve holes and affect the final analysis results.
[0004] This utility model provides an anti-jamming test sieve, including a sieve plate and sieve discs, wherein the sieve discs are rotatably mounted on the sieve plate;
[0005] It also includes sieve holes, which include a first opening area and a second opening area disposed opposite to each other, the first opening area being located on the sieve plate and the second opening area being located on the sieve plate.
[0006] The anti-jamming test sieve described in this application includes a sieve plate and a sieve disc. The sieve disc is rotatably mounted on the sieve plate. The sieve holes include a first opening area and a second opening area arranged opposite to each other. The first opening area is located on the sieve plate, and the second opening area is located on the sieve disc. During the test, when coarse aggregate gets stuck in the sieve holes, rotating the sieve disc separates the sieve disc from the sieve plate, thereby separating the second opening area on the sieve disc from the first opening area on the sieve plate, and thus separating the sieve holes. This allows the coarse aggregate to be easily removed from the sieve holes, reducing the time and labor intensity of cleaning the test sieve. The anti-jamming test sieve of this application can easily remove coarse aggregate stuck in the sieve holes without damaging the sieve holes or the aggregate, making the cleaning and maintenance of the test sieve simpler and faster, improving the screening efficiency and safety of the test sieve, reducing maintenance costs, effectively improving the accuracy of data, saving test time, and freeing up labor.
[0007] Preferably, the areas of the first opening region and the second opening region are equal.
[0008] Preferably, a plurality of the sieve holes are arranged in a row on the sieve plate and the sieve disc.
[0009] Preferably, the sieve holes in each row are spaced laterally apart.
[0010] Preferably, the sieve holes are rectangular in shape.
[0011] Preferably, the system further includes a hinge shaft mounted on the sieve plate, with the side of the sieve plate away from the second opening area connected to the hinge shaft. Each sieve plate is connected to the sieve plate via a hinge shaft, allowing the sieve plate to rotate relative to the sieve plate by rotating about the hinge shaft.
[0012] Preferably, the sieve also includes locking switches, which are disposed at both ends of the sieve plate, and the sieve plate is fixed to the sieve plate by the locking switches. The locking switches on the sieve plate are used to lock the sieve plate to the sieve plate during the sieving process, maintaining the normal working state of the test sieve.
[0013] Preferably, the sieve plate is provided with an installation area, and the sieve plate is located within the installation area.
[0014] Preferably, a bending plate is provided at the end area of the installation area, and the end of the sieve plate overlaps the bending plate;
[0015] The locking switch passes through the ends of the bending plate and the sieve plate.
[0016] Preferably, the locking switch is a pin.
[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0018] The anti-jamming test sieve described in this application includes a sieve plate and a sieve disc. The sieve disc is rotatably mounted on the sieve plate. The sieve holes include a first opening area and a second opening area arranged opposite to each other. The first opening area is located on the sieve plate, and the second opening area is located on the sieve disc. During the test, when coarse aggregate gets stuck in the sieve holes, rotating the sieve disc separates the sieve disc from the sieve plate, thereby separating the second opening area on the sieve disc from the first opening area on the sieve plate, and thus separating the sieve holes. This allows the coarse aggregate to be easily removed from the sieve holes, reducing the time and labor intensity of cleaning the test sieve. The anti-jamming test sieve of this application can easily remove coarse aggregate stuck in the sieve holes without damaging the sieve holes or the aggregate, making the cleaning and maintenance of the test sieve simpler and faster, improving the screening efficiency and safety of the test sieve, reducing maintenance costs, effectively improving the accuracy of data, saving test time, and freeing up labor.

[0034] Example 1
[0035] like Figures 1-6 The anti-jamming test sieve described in this embodiment includes a sieve plate 1 and a sieve disc 3, with the sieve disc 3 rotatably mounted on the sieve plate 1;
[0036] It also includes a sieve hole 2, which includes a first opening area 21 and a second opening area 22 that are arranged opposite to each other. The first opening area 21 is located on the sieve plate 1, and the second opening area 22 is located on the sieve plate 3.
[0037] like Figures 5-6As shown, during the test, when coarse aggregate gets stuck in the sieve hole 2, the sieve plate 3 is rotated to separate it from the sieve plate 1, thereby separating the second opening area 22 on the sieve plate 3 from the first opening area 21 on the sieve plate 1, and thus separating the sieve hole 2. This allows the coarse aggregate to be easily removed from the sieve hole, reducing the time and labor intensity of cleaning the test sieve. The anti-jamming test sieve of this embodiment can easily remove coarse aggregate stuck in the sieve hole 2 without damaging the sieve hole 2 or the aggregate, making the cleaning and maintenance of the test sieve simpler and faster, improving the screening efficiency and safety of the test sieve, reducing maintenance costs, effectively improving the accuracy of data, saving test time, and freeing up labor.
[0038] like Figure 2 As shown, in this embodiment, the first opening area 21 is disposed on the sieve plate 1, wherein adjacent first opening areas 21 are spaced apart.
[0039] like Figure 3 As shown, the second opening area 22 is disposed on the sieve plate 3, wherein adjacent second opening areas 22 are spaced apart;
[0040] The first opening area 21 and the second opening area 22, which are located at corresponding positions, combine to form the sieve hole 2.
[0041] In one or more embodiments, the areas of the first opening region 21 and the second opening region 22 are equal, that is, the screen hole 2 is divided into two equal parts, so that after the screen plate 1 is rotated, the area after the screen hole 2 is separated is large enough to make it easier to remove the coarse aggregate.
[0042] In optional implementations, such as Figure 1 As shown, multiple sieve holes 2 are arranged in rows on the sieve plate 1 and the sieve sheet 3. By arranging multiple sieve holes 2 in rows on the sieve plate 1 and the sieve sheet 3, the screening capacity of the test sieve can be improved.
[0043] That is, multiple first opening areas 21 are arranged in rows on the sieve plate 1, and multiple second opening areas 22 are arranged in rows on the sieve plate 3.
[0044] In an optional implementation, each row of sieve holes 2 is spaced laterally to avoid two sieve holes 2 being too close together and affecting screening efficiency.
[0045] In an optional embodiment, the sieve hole 2 is rectangular in shape.
[0046] In one or more embodiments, a hinge shaft 5 is also included, which is mounted on the sieve plate 1, and the side of the sieve plate 3 away from the second opening area 22 is connected to the hinge shaft 5.
[0047] Each sieve plate 3 is connected to the sieve plate 1 via a hinge shaft 5, so that the sieve plate 3 can rotate relative to the sieve plate 1 by rotating around the hinge shaft 5, thereby opening and closing the sieve hole 2.
[0048] In an optional implementation, the sieve plate 3 can be a hinged plate, such as... Figure 1 , Figure 5 , Figure 6 As shown, two sieve plates 3 are assembled into a hinged plate, and then the hinged plate is installed on the sieve plate 1 through the hinge shaft 5.
[0049] In an optional embodiment, the sieve plate 1 can be a metal plate.
[0050] In one or more implementations, such as Figure 1 , Figure 7 As shown, it also includes a locking switch 4, which is located at both ends of the screen plate 3. The screen plate 3 is fixed to the screen plate 1 by the locking switch 4.
[0051] A locking switch 4 is provided on the sieve plate 3 to lock the sieve plate 1 during the sieving process, so as to maintain the normal working state of the test sieve. Furthermore, the design of the locking switch 4 makes the operation of the test sieve simpler and improves the work efficiency.
[0052] In optional implementations, such as Figure 2 As shown, the sieve plate 1 is provided with an installation area 11, and the sieve plate 3 is located in the installation area 11;
[0053] Furthermore, such as Figure 2 , Figure 7 As shown, a bending plate 12 is provided at the end area of the installation area 11, and the end of the sieve plate 3 overlaps on the bending plate 12.
[0054] The locking switch 4 passes through the ends of the bending plate 12 and the sieve plate 3, thereby fixing the bending plate 12 and the sieve plate 3 together, and then fixing the sieve plate 3 on the sieve plate 1.
[0055] like Figure 2 As shown, in this embodiment, the sieve plate 1 is provided with an installation area 11, which is connected to the first opening area 21, so that after the sieve plate 3 is installed in the installation area 11, the second opening area 22 on the sieve plate 3 and the first opening area 21 form a sieve hole 2.
[0056] In an optional implementation, the locking switch 4 is a pin.
[0057] The operation mechanism of this embodiment is as follows:
[0058] During the experiment or screening process, the screen plate 3 is locked by the locking switch 4, making the screen plate 1 no different from an existing screen. When coarse aggregate gets stuck in the screen hole 2, the locking switch 4 that locks the screen plate 3 is opened, the screen plate 3 is flipped upwards, the screen hole 2 is opened, and the stuck aggregate can be easily removed.
[0059] The anti-jamming test sieve of this embodiment, through the design of adjustable sieve plates 3, reduces the situation where coarse aggregate gets stuck in the sieve holes 2, improves screening efficiency, effectively solves the problem of coarse aggregate getting stuck in the screening process of existing sieves, improves screening efficiency and safety, reduces maintenance costs, has significant economic and social benefits, and also avoids the risk of sieve damage or operator injury caused by aggregate getting stuck.
[0060] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
