Description

Technical Field

[0001] This utility model relates to the field of testing devices, and in particular to a device for testing the moisture content of manufactured sand. Background Technology

[0002] As a key aggregate in engineering construction, the moisture content of manufactured sand directly affects the quality and construction stability of concrete. The national standard (GB / T 14684) requires that the moisture content of manufactured sand be controlled within a reasonable range (usually ≤6%), otherwise it will lead to problems such as an imbalance in the water-cement ratio and a decrease in strength in the concrete. Currently, moisture content testing mainly relies on the drying and weighing method and electronic detection. The former is time-consuming and inefficient, while the latter is fast. Therefore, in actual production and daily life, electronic detection is more commonly used.

[0003] However, before using electronic detection, the sample needs to be compacted, and data from multiple points needs to be collected during the detection process to ensure the accuracy of the final data. Moreover, during the electronic detection process, the compacted manufactured sand often adheres to the inner wall of the container when discharged, causing difficulties in material discharge. Therefore, this solution proposes a device for detecting the moisture content of manufactured sand. Utility Model Content

[0004] The device for detecting the moisture content of manufactured sand proposed in this invention solves the problems of existing devices for detecting the moisture content of manufactured sand being unable to detect multiple points at once and the inconvenience of discharging samples.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] The equipment for testing the moisture content of manufactured sand includes a base and also includes:

[0007] The loading mechanism includes a mounting plate rotatably connected to the top of the base and two material-holding assemblies respectively mounted on the outer walls of the two sides of the mounting plate. The material-holding assemblies include a material bucket fixedly mounted on the outer wall of the mounting plate, a top material plate disposed inside the material bucket, a top material component installed inside the material bucket for driving the top material plate to move, and a flipping assembly installed on the mounting plate for driving the material bucket to flip.

[0008] The pressing mechanism includes a mounting frame installed on the top of the base, a pressing plate located above the base for pressing the sample in the material barrel, and a hydraulic cylinder installed on the mounting frame for driving the pressing plate to rise and fall. The pressing plate has a hollow structure.

[0009] The testing mechanism includes a lifting plate located above the pressure plate, multiple detectors mounted on the lifting plate, and a hydraulic cylinder mounted on a mounting frame for driving the lifting plate to rise and fall. The detectors include a main unit mounted on the lifting plate and a probe fixed to the bottom surface of the lifting plate and connected to the main unit. The mounting frame is equipped with a display connected to the multiple detectors for displaying test data. The pressure plate has an insertion hole for the probe to pass through.

[0010] A sealing mechanism, which is installed inside the pressure plate and is used to seal the jack when the pressure plate squeezes the sample in the hopper.

[0011] The above technical solution not only allows for convenient simultaneous detection of moisture content at multiple points, but also facilitates the flipping of the material bucket after detection. Furthermore, the flipping action can drive the top plate to move, thereby enabling the convenient discharge of the sample from the material bucket.

[0012] As a further improvement to the above solution, the flipping assembly includes two side plates fixed to the outer wall of the mounting plate and two transmission components respectively installed on the opposite outer walls of the two side plates. The material bucket is located between the two side plates. The transmission component includes a rotating shaft rotatably connected to the outer wall of the side plate, a telescopic component installed on the outer wall of the side plate, and a rack fixed to the output end of the telescopic component. The other end of the rotating shaft is fixed to the outer wall of the material bucket, and a gear that meshes with the rack is sleeved on the outer circumference of the rotating shaft.

[0013] As a further improvement to the above solution, the top material component includes a fixing plate fixed to the bottom of the inner side of the material barrel and a hydraulic cylinder three installed on the top of the fixing plate, wherein the output end of the hydraulic cylinder three is fixedly connected to the bottom surface of the top material plate.

[0014] As a further improvement to the above solution, the bottom of the material barrel is an open structure, and the inner ring of the material barrel is fixed with a limiting ring for limiting the descent depth of the top plate.

[0015] As a further improvement to the above solution, the sealing mechanism includes a fixed shaft rotatably connected to the center of the inner wall of the bottom of the pressure plate, a partition sleeved around the outer periphery of the fixed shaft, and a driving component installed on the top surface of the pressure plate for driving the fixed shaft to rotate. The bottom surface of the partition abuts against the inner wall of the bottom of the pressure plate, and multiple second insertion holes for probes to pass through are provided on the partition at the position corresponding to the first insertion hole. When the second insertion hole is offset from the first insertion hole, the partition seals the insertion hole.

[0016] As a further improvement to the above solution, the driving component includes a telescopic component II mounted on the top surface of the pressure plate, a rack II fixed to the output end of the telescopic component II, and the top of the fixed shaft extends to the top of the pressure plate and is fixed with a gear II that meshes with the rack II.

[0017] As a further improvement to the above solution, the mounting plate is located on one side of the top surface of the base. When one of the material buckets is directly above the base, the other material bucket is offset from directly above the base, and the bottom of the material bucket directly above the base abuts against the top surface of the base. A motor for driving the mounting plate to rotate is installed at the bottom of the base.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0019] 1. Through the cooperation between the compaction mechanism and the detection mechanism, not only can the sample in the barrel be compacted conveniently, but also the probes of multiple detectors can be inserted into the compacted sample at the same time, thereby facilitating and quickly completing multi-point measurements and ensuring the accuracy of the detection data.

[0020] 2. The sealing mechanism can easily block the insertion hole during the compaction process to prevent the sample from entering the inside of the pressure plate. It can also easily open the insertion hole during testing to allow the probe to pass through.

[0021] 3. The loading mechanism not only allows for easy tilting of the material barrel after testing to empty the sample inside, but also enables the top plate to rise via the top material component, thereby pushing the sample out of the barrel and preventing sample residue.

[0030] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0031] Example 1:

[0032] Please combine Figures 1-6 The device for detecting the moisture content of manufactured sand in this embodiment includes a base 1, and also includes:

[0033] The loading mechanism includes a mounting plate 2 rotatably connected to the top of the base 1 and two material-holding assemblies respectively mounted on the outer walls of both sides of the mounting plate 2. Each material-holding assembly includes a material hopper 4 fixedly mounted on the outer wall of the mounting plate 2, a top plate 5 disposed within the material hopper 4, a top member mounted within the material hopper 4 for driving the top plate 4 to move, and a tilting assembly mounted on the mounting plate 2 for driving the material hopper 4 to tilt. The tilting assembly includes two side plates 3 fixedly mounted on the outer wall of the mounting plate 2 and two transmission components respectively mounted on the opposite outer walls of the two side plates 3. The material hopper 4 is located between the two side plates 3. The transmission components include a rotating shaft 23 rotatably connected to the outer wall of the side plate 3 and a transmission component mounted on... The telescopic component 6 on the outer wall of the side plate 3 and the rack 22 fixed to the output end of the telescopic component 6, the other end of the rotating shaft 23 is fixed to the outer wall of the material barrel 4, and the gear 24 that meshes with the rack 22 is sleeved on the outer periphery of the rotating shaft 23. When it is necessary to pour out the sample in the material barrel 4, the material barrel 4 can be driven to flip by the flipping component. When the flipping component is running, the telescopic component 6 extends, thereby driving the rack 22 to move. After the rack 22 moves, it drives the gear 24 to rotate, thereby driving the rotating shaft 23 to rotate. The material barrel 4 also gradually flips with the rotation of the rotating shaft 23, thereby achieving the purpose of conveniently driving the material barrel 4 to flip and conveniently pouring out the sample in the material barrel 4.

[0034] The top material component includes a fixing plate 27 fixed to the bottom of the inner side of the material barrel 4 and a hydraulic cylinder 26 installed on the top of the fixing plate 27. The output end of the hydraulic cylinder 26 is fixed to the bottom surface of the top material plate 5. In order to prevent the sample from sticking to the inside of the material barrel 4, the hydraulic cylinder 26 is driven to extend while the material barrel 4 is tilted to pour out the sample. After the hydraulic cylinder 26 extends, it drives the top material plate 5 to rise, thereby gradually pushing the sample in the material barrel 4 out of the material barrel 4.

[0035] The pressing mechanism includes a mounting frame 7 installed on the top of the base 1, a pressing plate 9 located above the base 1 for pressing the sample in the material barrel 5, and a hydraulic cylinder 10 installed on the mounting frame 7 for driving the pressing plate 9 to rise and fall. The outer ring of the pressing plate 9 matches the inner ring of the material barrel 4. When testing the moisture content of the sample, the sample is poured into the material barrel 4. When the material barrel rotates to directly below the pressing plate 9, the hydraulic cylinder 10 is activated to descend, thereby driving the pressing plate 9 to descend. After the pressing plate 9 descends into the material barrel 4, it presses the sample in the material barrel 4. The pressing plate 9 stops when it descends to the set stroke, thus completing the compaction of the sample.

[0036] The testing mechanism includes a lifting plate 17 located above the pressure plate 9, multiple detectors mounted on the lifting plate 17, and a hydraulic cylinder 12 mounted on a mounting frame 7 for driving the lifting plate 17 to rise and fall. Each detector includes a main unit 11 mounted on the lifting plate 17 and a probe 13 fixed to the bottom surface of the lifting plate 17 and connected to the main unit 11. A display 8 connected to the multiple detectors and used to display test data is mounted on the mounting frame 7. The pressure plate 9 has an insertion hole 19 for the probe 13 to pass through. After the sample in the material bucket 4 is compacted, the hydraulic cylinder 12 extends, thereby driving the lifting plate 17 to descend. The descending lifting plate 17 then drives the probe 13 to descend, and the probe 13 passes through the insertion hole 19 to enter the sample, thereby detecting the moisture content in the sample. Data from multiple detectors are transmitted to the display 8 for display. By averaging multiple sets of test data, the testing personnel can obtain more accurate moisture content data. Simultaneous detection by the detectors improves testing efficiency.

[0037] In this embodiment, the mounting plate 2 is located on one side of the top surface of the base 1. When one of the material buckets 4 is directly above the base 1, the other material bucket 4 is offset from directly above the base 1, and the bottom of the material bucket 4 directly above the base 1 abuts against the top surface of the base 1. A motor for driving the mounting plate 2 to rotate is installed at the bottom of the base 1. With this arrangement, when the material bucket 4 is offset from directly above the base 1, its rotation will not be blocked by the base 1. Moreover, when the sample in the material bucket 4 is compacted, the bottom of the material bucket 4 abuts against the top of the base 1, and the base 1 can also play a supporting role for the material bucket 4. When it is necessary to change the position of the two material buckets 4, the mounting plate 2 can be rotated by starting the motor.

[0038] In this embodiment, the bottom of the material barrel 4 is an open structure, and the inner ring of the material barrel 4 is fixed with a limiting ring 25 for limiting the descent depth of the top plate. The open bottom of the material barrel 4 can prevent the sample from remaining inside the material barrel, while the limiting ring 25 can lift the top plate 5 when the sample is compacted, so as to prevent the hydraulic cylinder 26 from being subjected to excessive pressure.

[0039] In this embodiment, the telescopic component 6 is either an electric telescopic cylinder or a hydraulic cylinder.

[0040] Example 2:

[0041] Combination Figures 2-4 This embodiment is an improvement on embodiment 1, in that: the pressure plate 9 has a hollow structure, and a sealing mechanism for sealing the insertion hole 19 when squeezing the sample in the material barrel 4 is installed inside the pressure plate 9. The sealing mechanism includes a fixed shaft 18 rotatably connected to the center of the bottom inner wall of the pressure plate 9, a partition plate 20 sleeved on the outer periphery of the fixed shaft 18, and a driving component installed on the top surface of the pressure plate 9 for driving the fixed shaft 18 to rotate. The bottom surface of the partition plate 20 abuts against the bottom inner wall of the pressure plate 9, and multiple insertion holes 21 for the probe 13 to pass through are opened on the partition plate 20 at the positions corresponding to the insertion hole 19. In this configuration, after the insertion hole 21 is offset from the insertion hole 19, the partition plate 20 blocks the insertion hole 19. Before the pressure plate 9 compacts the sample, the partition plate 20 is driven to rotate so that the insertion hole 21 is offset from the insertion hole 19. This prevents the sample from entering the pressure plate 9 through the insertion hole 19 during the compaction process. After compaction is completed, the partition plate 20 is driven to rotate back so that the insertion hole 21 is aligned with the insertion hole 19. This allows the probe 13 to pass through the insertion hole 21 and then through the insertion hole 19, and finally be inserted into the sample to detect the moisture content. This achieves the purpose of conveniently blocking the insertion hole 19.

[0042] The driving component includes a telescopic component 2 14 mounted on the top surface of the pressure plate 9, a rack 2 16 fixed at the output end of the telescopic component 2 14, and a fixed shaft 18 extending above the pressure plate 9 and having a gear 2 15 meshing with the rack 2 16. The telescopic component 2 14 is used to drive the fixed shaft 18 to rotate, thereby facilitating the rotation of the partition 20.

[0043] In this embodiment, the telescopic component 14 is either an electric telescopic cylinder or a hydraulic cylinder.

[0044] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
