Description

Technical Field

[0001] This utility model relates to the field of concrete production technology, specifically to an adjustable aggregate moisture detection mechanism. Background Technology

[0002] In the fields of concrete production and building material testing, accurate control of aggregate moisture content is a key factor in ensuring the stability, strength, and durability of concrete mix design. Traditional methods for testing aggregate moisture content have significant limitations:

[0003] Outdated testing methods: Currently, most concrete mixing plants still use manual, timed sampling to determine moisture content, relying on oven drying. This method is time-consuming (usually 4-6 hours), has poor timeliness, and cannot reflect the dynamic changes in aggregate moisture in real time. This can easily lead to the actual water-cement ratio of the concrete deviating from the design value, affecting product quality.

[0004] Lack of particle size adaptability: The particle size distribution of aggregates (5-40mm) has a significant impact on detection accuracy. Coarse aggregates (above 20mm) require deep detection due to their high porosity and strong water absorption; fine aggregates (below 80 mesh) are prone to shallow detection errors due to their large surface area. Existing equipment mostly adopts a fixed depth detection mode, which cannot adapt to changes in particle size, resulting in a coexistence of a detection blind zone for coarse aggregates (error ±5%RH) and over-detection of fine aggregates (error ±3%RH).

[0005] Therefore, an adjustable aggregate moisture detection mechanism is proposed. Utility Model Content

[0006] The purpose of this invention is to provide an adjustable aggregate moisture detection mechanism to solve the problems mentioned in the background art.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an adjustable aggregate moisture detection mechanism, including a storage bin, a top frame, an adjustment mechanism, and a detection probe. The top frame is fixedly connected to the top of the storage bin. The adjustment mechanism includes two movable tubes that are movably connected. The movable tubes are fixedly connected to the top frame. The detection probe is fixedly connected to the bottom of the movable tubes. The bottom of the detection probe is conical, and a moisture sensor is provided through the side wall of the detection probe.

[0008] According to the above technical solution, the top frame includes a connecting plate coaxially arranged with the storage bin, and a plurality of connecting rods are fixedly connected to the outer wall of the connecting plate. The end of the connecting rod away from the connecting plate is fixedly connected to the inner wall of the storage bin.

[0009] According to the above technical solution, the movable tube is fixedly connected to the lower surface of the connecting plate, and a transmission tube is coaxially connected inside the lower movable tube. A transmission screw is provided through and rotatably on the end face of the connecting plate. The transmission screw is screwed into the inside of the transmission tube, and a drive motor for driving the transmission screw to rotate is provided on the top of the connecting plate.

[0010] According to the above technical solution, the movable tubes are provided with a limiting groove and a limiting block that are slidably connected to each other.

[0011] According to the above technical solution, a movable outer shell is sleeved on the outside of the transmission tube and movably provided. A rotating ring is rotatably provided inside the movable outer shell. A connecting wire is fixedly connected to the surface of the rotating ring.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: an adjustable aggregate moisture detection mechanism, including a storage bin 1, a top frame 2, an adjustment mechanism, and a detection probe 3, such as... Figure 1 As shown, the top frame 2 is fixedly connected to the top of the storage bin 1. The adjustment mechanism includes two movable tubes 4 that are movably connected. The movable tubes 4 are fixedly connected to the top frame 2. The detection probe 3 is fixedly connected to the bottom of the movable tube 4. The bottom of the detection probe 3 is conical. A humidity sensor 5 is installed through the side wall of the detection probe 3. The conical structure on the surface of the detection probe 3 reduces the insertion resistance. The surface is coated with a nano-hydrophobic coating to effectively prevent the adhesion of aggregate moisture. The movable tubes 4 slide relative to each other to control the depth of the detection probe 3 inserted into the aggregate.

[0022] Specifically, the top frame 2 includes a connecting plate 201 coaxially arranged with the storage bin 1. A plurality of connecting rods 202 are fixedly connected to the outer wall of the connecting plate 201. The end of the connecting rod 202 away from the connecting plate 201 is fixedly connected to the inner wall of the storage bin 1.

[0023] Specifically, the movable tube 4 is fixedly connected to the lower surface of the connecting plate 201, and a transmission tube 6 is coaxially connected inside the lower movable tube 4, such as... Figure 1 As shown, the lower movable tube 4 is movably disposed on the inner wall of the upper movable tube 4. The end face of the connecting plate 201 is provided with a transmission screw 7 that is rotatably disposed through it. The transmission screw 7 is located inside the movable tube 4 and is coaxially disposed with the movable tube 4. The transmission screw 7 is screwed into the inside of the transmission tube 6. The top of the connecting plate 201 is provided with a drive motor 8 that drives the transmission screw 7 to rotate. The drive motor can be connected to the transmission screw 7 through a reducer and a coupling. When the transmission screw 7 rotates, the relative sliding of the movable tube 4 can be controlled by the threaded engagement.

[0024] Specifically, the movable tubes 4 are provided with a limiting groove 9 and a limiting block 10 that are slidably connected, such as... Figure 4As shown, a limiting block 10 is provided on the surface of the inner movable tube 4, and a limiting groove 9 is provided on the inner wall of the upper movable tube 4 to prevent aggregate from getting stuck in the limiting groove 9 and affecting the transmission of the movable tube 4. When the movable tube 4 slides relative to each other, the limiting groove 9 and the corresponding limiting block 10 move relative to each other to prevent the movable tube 4 from rotating relative to each other, so that the transmission screw 7 and the transmission tube 6 can rotate relative to each other.

[0025] Specifically, a movable outer shell 11 is sleeved and movably provided on the outer side of the transmission tube 6, such as... Figure 2 As shown, a rotating ring 12 is rotatably mounted inside the movable housing 11. The rotating ring 12 is coaxially arranged with the movable housing 11. A connecting wire 13 is fixedly connected to the surface of the rotating ring 12. Specifically, the surface of the connecting wire 13 is directly fixed to the surface of the rotating ring 12. Rotation of the rotating ring 12 synchronously tightens both ends of the connecting wire 13. The two ends of the connecting wire 13 pass through the movable housing 11 and are electrically connected to the humidity sensor 5 and the receiving device, respectively. The receiving device is used to receive the electrical signal transmitted by the humidity sensor 5 for humidity detection. The wired connection is more reliable and reduces interference. When the movable tube 4 slides relative to the rotating ring 12, the connecting wire 13 drives the rotating ring 12 to rotate, and the connecting wire 13 extends synchronously. Figure 3 As shown, a connecting sleeve is coaxially connected to the inner wall of the movable outer shell 11. The connecting sleeve is movably connected to the transmission tube 6. Matching grooves and sliders can be provided on the surfaces of the connecting sleeve and the transmission tube 6 to restrict the degree of freedom of the movable outer shell 11 (not shown in the figure), so that the sliding of the movable outer shell 11 is more stable and will not rotate relative to the transmission tube 6.

[0026] like Figure 3 As shown, in order to reduce the friction between the connecting wire 13 and the movable housing 11, the connecting wire 13 is flat in shape. The side wall of the movable housing 11 is provided with a through groove for the connecting wire 13 to pass through, and two rotating rollers are symmetrically arranged inside the through groove. The connecting wire 13 passes through the two rotating rollers.

[0027] Specifically, an elastic element is provided between the rotating ring 12 and the movable outer shell 11, such as... Figure 3 As shown, a first annular groove is coaxially provided on the inner wall of the rotating ring 12, and a second annular groove corresponding to the first annular groove is provided inside the movable outer shell 11. The elastic element can be a torsion spring, which is set inside the annular cavity formed by the first annular groove and the second annular groove, so that the rotating ring 12 tends to tighten the connecting wire 13. When the movable tube 4 retracts, the connecting wire 13 can be automatically retracted into the interior of the movable outer shell 11.

[0028] In use, this invention selects the insertion point based on the aggregate particle size. The drive motor 8 drives the transmission screw 7 to rotate. Under the action of the threaded engagement, the transmission tube 6 slides relative to the transmission screw 7, causing the movable tube 4 to slide relative to it. The detection probe 3 is inserted into the aggregate, and the humidity sensor 5 detects the humidity inside the aggregate. During this process, the connecting wire 13 drives the rotating ring 12 to rotate relative to the movable housing 11 to accommodate the elongation of the movable tube 4 and maintain the connection between the humidity sensor 5 and the receiving device. When the movable tube 4 shortens, under the action of the elastic element, the rotating ring 12 tightens the connecting wire 13 and enters the movable housing 11.

[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
