Abstract
Description
Technical Field
[0001] This application relates to the technical field of mud content detection devices, and in particular to a mud content detection device for sand and gravel. Background Technology
[0002] Clay content refers to the amount of fine particles (smaller than 75 micrometers) in sand and gravel that differ in mineral composition and chemical composition from the parent rock and have relatively strong adsorption properties. Clay in natural sand and gravel mainly originates from dust, silt, and clay in water. Clay in manufactured sand originates from mud or other impurities mixed in with rock fragments, which are not thoroughly washed before being crushed and mixed into the manufactured sand. While a certain amount of particles smaller than 75 micrometers in sand and gravel can be beneficial in increasing the density and strength of concrete, excessive clay content can negatively impact the workability, mechanical properties, and durability of concrete. Therefore, the accuracy of clay content testing is crucial.
[0003] The water washing method is a common method for detecting the mud content of sand and gravel. The steps are as follows: Take a certain amount of sand and gravel sample, mix it with a certain amount of water, and stir evenly. After standing for a period of time, the sand and gravel particles will settle, while the upper turbid liquid contains mud, impurities, and other components. Pour off the upper turbid liquid and repeat the process until the upper liquid is basically clear. Finally, pass the remaining sand and gravel particles through a 75-micron test sieve, dry them, and weigh them. The mud content of the sand and gravel is determined by calculating the ratio of the mass of the remaining sand and gravel particles to the mass of the original sand and gravel sample. In existing technologies, manual washing is often used during the washing process. Manual washing easily causes the loss of sand and gravel particles, and some mud and impurities are difficult to wash out, affecting the test results. The test personnel need to operate very carefully, which consumes a lot of time and energy. Summary of the Invention

[0029] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0030] This application discloses a device for detecting the mud content of sand and gravel.
[0031] Reference Figure 1 and Figure 2 A sand and gravel mud content detection device includes a base 1, a separating screen 2, a receiving plate 3, a frame 4, a connecting rod 5, and a drive mechanism 6. The base 1 includes a first seat body 11 and a second seat body 12. The first seat body 11 is fixed to the top surface of the second seat body 12. An inner cavity 14 is provided in the middle of the first seat body 11. The frame 4, the separating screen 2, and the receiving plate 3 are installed in the inner cavity 14 to optimize the equipment space.
[0032] Specifically, the frame 4 includes a first guide rail 41, a second guide rail 42, and a connecting plate 43. The connecting plate 43 connects the first guide rail 41 and the second guide rail 42, so that the first guide rail 41 is set on top of the second guide rail 42. The separating screen 2 slides on the first guide rail 41, and the receiving plate 3 slides on the second guide rail 42. The separating screen 2 and the receiving plate 3 are connected by a connecting rod 5. The separating screen 2 and the receiving plate 3 are coaxially arranged. The drive mechanism 6 is installed on the base 1 and its output end is assembled with the connecting rod 5. The drive mechanism 6 is used to drive the connecting rod 5 to slide horizontally on the base 1.
[0033] This application provides stable support and guidance for the separating screen plate 2 and the receiving plate 3 by setting the first guide rail 41 and the second guide rail 42, while the setting of the connecting plate 43 can make the entire frame 4 more stable, which helps to resist the vibration and impact generated during the screening process, so that the screening process has higher stability and accuracy.
[0034] Reference Figure 2 and Figure 3 A feed guide 7 is fixed on the top surface of the base 1. This application does not limit the specific shape of the feed guide 7; it can be a circular tube. A feed inlet is provided through the top of the base 1, so that the feed guide 7, the feed inlet, and the separating screen 2 are coaxially arranged. This application requires the feed guide 7 to have the function of guiding the sand and gravel feed, so as to realize the convenient feeding of sand and gravel raw materials and enable the sand and gravel raw materials to enter the screen 2 accurately and evenly for screening.
[0035] To achieve synchronous movement of the separating screen 2 and the receiving plate 3, a sliding groove 13 is provided on the top surface of the machine base 1. The extension direction of the sliding groove 13 is consistent with the movement direction of the push rod 63. The top end of the connecting rod 5 is assembled with the push rod 63, and at the same time, the top end of the connecting rod 5 slides in contact with the sliding groove 13. By providing the sliding groove 13, a stable movement track is provided for the connecting rod 5, ensuring the stability of the connecting rod 5 during the sliding process.
[0036] The connecting rod 5 and the separating screen 2, as well as the connecting rod 5 and the receiving plate 3, are detachably connected. This application does not specifically limit which connection method is used. Bolt connection can be used for fixing, which makes the maintenance and replacement of the device more convenient, helps to reduce maintenance costs, and makes the device more flexible and adaptable. Different specifications of screens and receiving plates 3 can be quickly adjusted or replaced according to actual needs to meet the detection requirements in different scenarios.
[0037] Reference Figure 2 and Figure 3 The drive mechanism 6 includes a fixed plate 61, a connecting rod assembly, a push rod 63, and a drive motor 64. The fixed plate 61 is mounted on the top surface of the base 1. The drive motor 64 is mounted on one side of the fixed plate 61. The output end of the drive motor 64 is mounted with the connecting rod assembly. A slide rail 65 is provided at the end of the fixed plate 61 away from the connecting rod assembly. The output end of the connecting rod assembly is mounted with the push rod 63. At the same time, the push rod 63 slides on the slide rail 65. The end of the push rod 63 away from the connecting rod assembly is mounted with the connecting rod 5.
[0038] More specifically, the linkage assembly in this application includes a first linkage 621 and a second linkage 622. The first linkage 621 is connected to the output of the drive motor 64 at one end, the second linkage 622 at the other end, and the second linkage 622 at the other end, all via shaft connections. The drive motor 64, as a power source, causes the first linkage 621 and the second linkage 622 to oscillate, driving the push rod 63 to move linearly along the slide rail 65. This, in turn, causes the separating screen 2 and the receiving screen 3 mounted on the connecting rod 5 to slide horizontally. That is, the separating screen 2, used to receive raw materials, can slide left and right. Under the action of water washing, large particles of sand and gravel can be retained in the separating screen 2, while small particles of soil are washed and vibrated into the receiving screen 3. Compared with the prior art, this improves the automation level of screening, reduces the need for manual intervention, and minimizes experimental errors.

These embodiments are merely explanations of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape, and principle of this application should be covered within the scope of protection of this application.
