Description

Technical Field

[0001] This utility model relates to the field of concrete technology, and to a device for detecting the particle size distribution of concrete aggregates. Background Technology

[0002] The particle size distribution of concrete aggregates refers to the proportional relationship of different sizes of particles in the aggregate. This gradation has a significant impact on the performance and cost of concrete.

[0003] Currently, in order to ensure the quality of concrete, it is generally necessary to test the aggregate particle size distribution in the concrete after the mix proportions are completed. At this time, the concrete is sampled and then a vibrating screen is used to separate the aggregates of different gradations for a more intuitive observation of the aggregate particle size distribution. During this process, the sampled concrete may not be mixed evenly, which may result in the collected samples not being representative, thus affecting the accuracy of the aggregate particle size distribution test results.

[0004] To address the aforementioned problems, this application proposes a device for detecting the particle size distribution of concrete aggregates. Utility Model Content

[0005] This invention addresses the technical problems existing in the prior art by providing a device for detecting the particle size distribution of concrete aggregates.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A device for detecting the particle size distribution of concrete aggregates includes a sampling structure and a vibrating screen. The sampling structure includes an operating table, multiple material distribution threaded pipes and multiple threaded rings. The multiple material distribution threaded pipes are arranged in sequence, and the multiple threaded rings are threadedly connected to the outside of the multiple material distribution threaded pipes.

[0007] Both ends of the multiple material distribution threaded tubes are made of iron, and one of the material distribution threaded tubes has a circular magnetic plate magnetically attracted to one end;

[0008] The control panel includes a panel, on which a square magnetic plate is placed;

[0009] The feed threaded pipe is equipped with a gripping component.

[0010] The thickness of the circular magnetic plate is equal to the thickness of the square magnetic plate.

[0011] A base post is installed at the bottom of the panel. The total height of the base post and the panel is equal to the height of the material distribution threaded tube. By setting the base post, the multiple material distribution threaded tubes can be separated more easily by the base post cooperating with the panel.

[0012] The gripping assembly includes a detachable handle installed on the outside of one of the feed threaded pipes and two clamping plates. By setting the gripping assembly, it is easy to hold the sampling structure and insert it into the concrete to take samples.

[0013] The grip is equipped with a support rod, one of the clamping plates is mounted on the support rod, the support rod has a sliding groove, the support rod is slidably connected to a slide plate through the sliding groove, the other clamping plate is mounted on the slide plate, and a threaded rod is rotatably connected to the support rod, the outer side of the threaded rod is threadedly connected to the slide plate. By setting up the support rod, sliding groove, slide plate, threaded rod and two clamping plates, the gripping assembly is fixed on the material distribution threaded pipe.

[0014] A knob is installed at one end of the threaded rod, which facilitates the rotation of the threaded rod.

[0015] The support rod is equipped with a bearing, and the outer side of the threaded rod is connected to the inner ring of the bearing. The bearing is used to support the threaded rod and assist its rotation.

[0016] The beneficial effects of this utility model are:

[0017] By setting up a sampling structure, multiple threaded tubes for material distribution are connected using multiple threaded rings. Then, the connected multiple threaded tubes are inserted into the concrete for sampling. Then, a circular magnetic suction plate and a square magnetic suction plate are used to block one side of each threaded tube. The concrete in each threaded tube is observed to roughly determine whether the concrete mix proportion is uniform. This avoids the possibility that the materials inside the sampled concrete are not mixed evenly, which would affect the accuracy of the aggregate particle size distribution test results.

[0018] By setting up the gripping assembly, one side of the support rod is attached to one side of the circular magnetic plate. Then, by turning the knob, the two clamping plates are fixed to the outside of the feed thread tube, thus achieving the effect of assembling the grip and helping the operator to operate the sampling structure by hand.

[0019] By attaching a circular magnetic plate to the ground and placing a square magnetic plate on the panel, and then moving the second splitting threaded tube from bottom to top, the square magnetic plate is attracted to the bottom of the splitting threaded tube. This method separates all the splitting threaded tubes, thus achieving the effect of easier separation of all the splitting threaded tubes. Attached Figure Description

[0030] Reference Figure 1A device for detecting the particle size distribution of concrete aggregate includes a sampling structure 1 and a vibrating screen 2. The sampling structure 1 includes an operating table 105, multiple distribution threaded tubes 101, and multiple threaded rings 102. The multiple distribution threaded tubes 101 are arranged sequentially, and the multiple threaded rings 102 are threadedly connected to the outside of the multiple distribution threaded tubes 101. Both ends of the multiple distribution threaded tubes 101 are made of iron, and one end of one of the distribution threaded tubes 101 is magnetically attracted to a circular magnetic suction plate 103. The operating table 105 includes a panel 1051, on which a square magnetic suction plate 104 is placed. Specifically, according to the above technical solution, the multiple threaded rings 102 are used to hold the multiple distribution threaded tubes 101 together. 01 Connect the components, then insert the connected multiple distribution threaded tubes 101 into the concrete for sampling. Then, separate the distribution threaded tubes 101 with circular magnetic suction plates 103, and use square magnetic suction plates 104 to block one side of each remaining distribution threaded tube 101. At this time, observe the concrete in each distribution threaded tube 101 to roughly determine whether the concrete mix ratio is uniform, and try to avoid the fact that the internal materials of the sampled concrete are not mixed evenly, which would affect the accuracy of the aggregate particle size distribution test results. After the judgment is completed and the concrete mix ratio is uniform, pour the concrete in each distribution threaded tube 101 into the vibrating screen 2 to separate aggregate particles of different gradations.

[0031] Among them, the vibrating screen 2 adopts the YK1230 produced by Henan Ruimeite Industrial Co., Ltd.

[0032] Reference Figure 2 The thickness of the circular magnetic plate 103 is equal to the thickness of the square magnetic plate 104. A base post 1052 is installed at the bottom of the panel 1051. The total height of the base post 1052 and the panel 1051 is equal to the total height of the distribution threaded tube 101 and the circular magnetic plate 103. According to the above technical solution, specifically, the circular magnetic plate 103 is attached to the ground, and a square magnetic plate 104 is placed on the panel 1051. Then, the second distribution threaded tube 101 is moved from bottom to top, so that the bottom of the distribution threaded tube 101 is attracted to the square magnetic plate 104. In this way, all the distribution threaded tubes 101 are separated, thereby achieving the effect of easier separation of all the distribution threaded tubes 101.

[0033] Reference Figure 2 and Figure 3A gripping assembly 3 is provided on the feed threaded pipe 101. The gripping assembly 3 includes a handle 308 detachably installed on the outside of one of the feed threaded pipes 101 and two clamping plates 302. A support rod 301 is installed on the handle 308. One clamping plate 302 is installed on the support rod 301. A sliding groove 303 is provided on the support rod 301. A sliding plate 304 is slidably connected to the support rod 301 through the sliding groove 303. The other clamping plate 302 is installed on the sliding plate 304. A threaded rod 305 is rotatably connected to the support rod 301. The outside of the threaded rod 305 is threadedly connected to the sliding plate 304. A knob 307 is installed at one end of the 5, and a bearing 306 is installed on the support rod 301. The outer side of the threaded rod 305 is connected to the inner ring of the bearing 306. According to the above technical solution, specifically, by attaching one side of the support rod 301 to one side of the circular magnetic plate 103, and then rotating the knob 307, the threaded rod 305 is driven to rotate. The rotation of the threaded rod 305 drives one of the clamping plates 302 to move, thereby fixing the two clamping plates 302 to the outside of the feed threaded tube 101, thus achieving the effect of assembling the handle 308, which helps the operator to hold the sampling structure 1 for operation.

[0034] Working principle:

[0035] The device for detecting the particle size distribution of concrete aggregates works by attaching one side of the support rod 301 to one side of the circular magnetic plate 103. Then, by rotating the knob 307, the threaded rod 305 is rotated. The rotation of the threaded rod 305 causes one of the clamping plates 302 to move, thereby fixing the two clamping plates 302 to the outside of the material distribution threaded tube 101. This achieves the effect of assembling the handle 308, which helps the operator to hold the sampling structure 1 for operation.

[0036] The device for detecting the particle size distribution of concrete aggregates has a circular magnetic plate 103 attached to the ground and a square magnetic plate 104 placed on the panel 1051. Then, the second distribution threaded tube 101 is moved from bottom to top, so that the bottom of the distribution threaded tube 101 is attracted to the square magnetic plate 104. In this way, all the distribution threaded tubes 101 are separated, thereby achieving the effect of easier separation of all the distribution threaded tubes 101.

[0037] The device for detecting the particle size distribution of concrete aggregates uses multiple threaded rings 102 to connect multiple distribution threaded tubes 101. Then, the connected multiple distribution threaded tubes 101 are inserted into the concrete for sampling. Subsequently, the distribution threaded tubes 101 with circular magnetic suction plates 103 are separated, and one side of each remaining distribution threaded tube 101 is blocked using square magnetic suction plates 104. At this time, the concrete in each distribution threaded tube 101 is observed to roughly determine whether the concrete mix is ​​uniform, thus avoiding the possibility that the materials inside the sampled concrete are not mixed evenly, which would affect the accuracy of the aggregate particle size distribution test results. After the judgment is completed and the concrete mix is ​​uniform, the concrete in each distribution threaded tube 101 is poured into a vibrating screen 2 to separate aggregate particles of different gradations.
