Description

Technical Field

[0001] This utility model belongs to the field of concrete testing technology, specifically relating to a concrete moisture content testing device. Background Technology

[0002] Concrete is one of the most commonly used materials in construction engineering. Its strength, durability, and other properties are closely related to the moisture content of the concrete. Therefore, accurate and reliable detection of the moisture content of concrete is crucial to ensuring the quality and safety of construction projects. The moisture content of concrete not only affects its strength and durability but also directly relates to its workability and subsequent maintenance. Currently, the weighing method is the simplest way to detect the moisture content of concrete. The specific method involves taking a sample of concrete, drying the moisture at a high temperature, and then measuring the change in mass after drying to calculate the moisture content of the concrete.

[0003] Common concrete moisture content testing devices have a relatively simple structure and lack a crushing mechanism. In actual use, the moisture in block concrete samples is difficult to evaporate quickly, resulting in reduced testing efficiency. Furthermore, during the testing process, the concrete sample is usually kept still, which leads to uneven heating and further prolongs the testing time, making them impractical. Utility Model Content

[0004] The purpose of this invention is to provide a concrete moisture content testing device to solve the technical problems of low testing efficiency and insufficient practicality, thereby improving testing efficiency and practicality.

[0005] To solve the above-mentioned technical problems, this utility model provides a concrete moisture content testing device, including a box, a crushing mechanism installed on the back of the box near the top, and a mixing mechanism installed inside the box near the top.

[0006] The back of the box has a feed inlet corresponding to the crushing mechanism, the top of the box has an exhaust vent near the back, and the bottom of the box has a weighing component.

[0007] The crushing mechanism includes a fixed seat, which is fixedly installed on the back of the housing. A groove is provided inside the fixed seat near the front. A pushing component is installed on the back of the fixed seat extending into the groove. Hydraulic cylinders are symmetrically installed on the left and right sides inside the fixed seat. A clamping plate is fixedly connected to the output end of the hydraulic cylinder.

[0008] The stirring mechanism includes an electric push rod, which is fixedly installed at the top of the housing. The output end of the electric push rod extends into the interior of the housing and is fixedly connected to a slide block. An electric slider is slidably connected inside the slide block, and a stirring assembly is installed at the bottom of the electric slider.

[0009] Furthermore, a control panel is installed at the top of the box near the front and left corners, and drying lamp panels are symmetrically installed on the left and right sides inside the box, with the drying lamp panels electrically connected to the control panel.

[0010] Furthermore, a guide plate is installed inside the feed inlet and inside the housing.

[0011] Furthermore, several fans are installed equidistantly from left to right inside the exhaust vent, and a dustproof net is installed inside the exhaust vent and at the top of the fans. The fans are electrically connected to the control panel.

[0012] Furthermore, the weighing assembly includes a weighing module, which is fixedly connected to the housing and electrically connected to the control panel. A tray is mounted on the top of the weighing module.

[0013] Furthermore, the pushing component includes a slide rod that is slidably connected to a fixed base, and a push plate is welded to one end of the slide rod that extends into the groove.

[0014] Furthermore, the stirring assembly includes a motor, which is fixedly connected to an electric slider, and a stirring frame is fixedly connected to the output end of the motor.

[0015] The beneficial effects of this utility model are:

[0016] 1. By using a hydraulic cylinder to move the clamping plate inward, the concrete sample placed inside the groove can be crushed into fine particles. The crushed concrete sample is then transported to the tray above for drying via a pushing component. Compared with traditional testing devices, this greatly accelerates the rate of moisture loss from the concrete sample and effectively improves testing efficiency.

[0017] 2. By using the electric push rod, slide, electric slider and mixing components together, the concrete sample on the tray can be stirred and turned to prevent squeezing, making the concrete sample dry more evenly, increasing the drying speed and effectively improving its practicality.

[0026] Example:

[0027] like Figures 1 to 3As shown, a concrete moisture content testing device includes: a housing 1; a crushing mechanism 2 is installed on the back of the housing 1 near the top; a mixing mechanism 3 is installed inside the housing 1 near the top; a feed inlet 101 is provided on the back of the housing 1 corresponding to the crushing mechanism 2; an exhaust vent 102 is provided at the inner top of the housing 1 near the back; and a weighing component 103 is installed at the inner bottom of the housing 1. The crushing mechanism 2 includes a fixing seat 201, which is fixedly installed on the back of the housing 1. A groove 202 is provided inside the fixing seat 201 near the front; the back of the fixing seat 201 extends into the groove 202. The push assembly 203 is installed, and hydraulic cylinders 204 are symmetrically installed on the left and right sides inside the fixed base 201. The output end of the hydraulic cylinder 204 is fixedly connected to the clamping plate 205. The stirring mechanism 3 includes an electric push rod 301, which is fixedly installed on the top of the box 1. The output end of the electric push rod 301 extends into the inside of the box 1 and is fixedly connected to the slide 302. An electric slider 303 is slidably connected inside the slide 302. The stirring assembly 304 is installed at the bottom of the electric slider 303. The hydraulic cylinder 204, the electric push rod 301 and the electric slider 303 are all electrically connected to the control panel 104.

[0028] like Figures 1 to 3As shown, a control panel 104 is installed at the top of the box 1 near the front and left corners. Drying lamp plates 105 are symmetrically installed on the left and right sides inside the box 1. The drying lamp plates 105 are electrically connected to the control panel 104, allowing for quick opening and closing of the drying lamp plates 105, improving ease of use. A guide plate 1011 is installed inside the feed inlet 101 and within the box 1. The guide plate 1011 allows the crushed concrete sample to fall accurately into the tray 1032, improving operational stability. An exhaust vent... Inside chamber 102, several fans 1021 are installed at equal intervals from left to right. A dust filter is installed inside the exhaust vent 102 and at the top of each fan 1021. The fans 1021 are electrically connected to the control panel 104. The fans 1021 drive moisture vapor inside chamber 1 out through the exhaust vent 102, improving drying efficiency. The weighing assembly 103 includes a weighing module 1031, which is fixedly connected to chamber 1 and electrically connected to the control panel 104. A tray 1032 is mounted on the top of the weighing module 1031. The weighing module 1031 can accurately weigh concrete samples before and after drying, and transmit the difference to the control panel 104 for moisture content calculation, improving ease of use. The pushing component 203 includes a slide rod 2031, which is slidably connected to the fixed base 201. A push plate 2032 is welded to one end of the slide rod 2031 that extends into the groove 202. By pushing the slide rod 2031, the push plate 2032 can be driven to slide back and forth, thereby pushing the crushed concrete sample inside the groove 202 through the feed inlet 101 and... The guide plate 1011 pushes the material onto the tray 1032 for drying and weighing, improving ease of use. The mixing component 304 includes a motor 3041, which is fixedly connected to an electric slider 303. The output end of the motor 3041 is fixedly connected to a mixing rack 3042. The motor 3041 is electrically connected to the control panel 104. The electric slider 303 can drive the mixing component 304 to move back and forth, and in conjunction with the motor 3041, it can drive the mixing rack 3042 to stir and turn the concrete sample inside the tray 1032, improving the uniformity of drying.

[0029] In summary, when using a concrete moisture content testing device to detect concrete moisture content, a suitable-sized block concrete sample is first placed inside the groove 202. The control panel 104 then controls the hydraulic cylinder 204 to extend the clamping plate 205 inwards until the concrete sample is crushed. Afterwards, the hydraulic cylinder 204 retracts, causing the clamping plate 205 to reset and push the sliding rod 2031 forward. This causes the pusher plate 2032 to push the crushed concrete sample from the inlet 101 through the guide plate 1011 into the housing 1, and then through the guide plate into the tray 1032. Simultaneously, the weighing module 1031 weighs the concrete sample in the tray 1032 and transmits the weight information to the control panel 104 in real time. Finally, the control panel 104 controls the drying lamp plate 105 to begin operation. The process involves drying the concrete sample inside the tray 1032. Simultaneously, the electric push rod 301 drives the slide 302 downward until the mixing rack 3042 is close to the inner bottom of the tray 1032. Then, the motor 3041 drives the mixing rack 3042 to rotate and stir the concrete sample inside the tray 1032. At the same time, the electric slider 303 drives the mixing component 304 to move back and forth along the slide 302, making the drying and heating more uniform. At the same time, the fan 1021 starts working to draw the evaporated moisture out of the chamber 1 through the exhaust port 102. After the concrete sample is completely dried, the control panel 104 takes the initial weight information and the weight after drying to calculate the moisture content, completing the entire testing process. Compared with traditional testing devices, this greatly improves the testing efficiency and effectively enhances practicality.
