Description

Technical Field

[0001] The present invention belongs to the technical field of concrete aggregate detection, and specifically relates to a device for detecting the moisture content of concrete aggregates. Background Art

[0002] In the field of construction engineering, concrete is a widely used building material, and concrete aggregates are an important component of concrete. The moisture content of aggregates has a crucial impact on the performance of concrete. The performance of concrete, such as strength, durability, etc., is closely related to the moisture content of aggregates. Accurately measuring the moisture content of aggregates is of great significance for ensuring the quality of concrete. However, in the actual detection process, there are many factors affecting the accuracy of aggregate moisture content detection.

[0003] In the existing related technologies, firstly, during the placement and distribution of aggregates by traditional equipment, due to the lack of effective vibration and buffering mechanisms, the aggregates are prone to accumulation or uneven distribution, resulting in large errors in the detection results. In addition, the impact force generated when the aggregates fall may damage the equipment, affecting the stability and service life of the equipment.

[0004] Secondly, the moisture content measuring device of the existing equipment is easily interfered by the external environment (such as temperature, humidity, dust, etc.) under complex working conditions, resulting in a decrease in measurement accuracy. Especially in a high-dust environment, the accumulation of dust will not only affect the sensitivity of the measuring device but also may hinder the normal operation of the equipment.

Specific embodiments

[0023] Embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the accompanying drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0024] A wet content detection device for concrete aggregates according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0025] As Figures 1 to 14 shown, an embodiment of the present invention provides a wet content detection device for concrete aggregates, including: A working cylinder 1, a partition plate 45 is provided in the inner cavity of the working cylinder 1, an aggregate limiting frame 10 is provided above the partition plate 45, a sealing cover 33 is provided at the top of the aggregate limiting frame 10, and an L-shaped support leg 3 is further provided on the outside of the working cylinder 1. There are four groups of L-shaped support legs 3, and anti-slip plates 4 are provided at the bottoms of the four groups of L-shaped support legs 3, and anti-slip patterns are provided at the bottoms of the four groups of anti-slip plates 4; An aggregate placement mechanism 11, which is arranged inside the aggregate limiting frame 10. The aggregate placement mechanism 11 includes a concave bearing plate 12, a vibrator 15, an aggregate falling buffer plate 16, a moisture content measurer 17, a concave fixing plate 18, an electric telescopic component 25, a moisture content measurer control button 26 and a vibrator control button 43. The concave bearing plate 12 is arranged at the bottom of the inner cavity of the aggregate limiting frame 10, the aggregate falling buffer plate 16 is arranged inside the concave bearing plate 12, the vibrator 15 is arranged at the bottom of the aggregate falling buffer plate 16, and the vibrator 15 is electrically controlled and connected to the vibrator control button 43 through a transmission wire. The concave fixing plate 18 is arranged above the concave bearing plate 12, the moisture content measurer 17 is arranged inside the concave fixing plate 18, the moisture content measurer control button 26 and the vibrator control button 43 are both arranged on the inner wall of the concave fixing plate 18, and the electric telescopic component 25 is respectively arranged below the concave bearing plate 12 and above the concave fixing plate 18.

[0026] In the specific application of the embodiment of the present invention, the aggregate limiting frame 10 is located in the inner cavity of the working cylinder 1, and an aggregate placement mechanism 11 is arranged inside it. The concrete aggregates to be detected fall into the inside of the aggregate limiting frame 10 and at the same time fall above the aggregate falling buffer plate 16. The concave bearing plate 12 can stably carry the aggregates and prevent them from sliding or being unevenly distributed.

[0027] The aggregate falls into the buffer plate 16 which is located inside the concave bearing plate 12, used to slow down the impact force when the aggregate falls, avoiding the aggregate from being broken or unevenly distributed due to the impact. The vibrator 15 is installed at the bottom of the buffer plate 16 where the aggregate falls, and is automatically controlled through the vibrator control button 43. After starting the vibrator 15, its vibration effect makes the aggregate evenly distributed on the concave bearing plate 12, providing a uniform sample for subsequent moisture content detection. The concave fixed plate 18 is located above the concave bearing plate 12, and a moisture content measuring device 17 is installed inside it. The moisture content measuring device 17 is automatically controlled through the moisture content measuring device control button 26. After the aggregate is evenly distributed on the concave bearing plate 12, the electric telescopic device assembly 25 starts to work. The electric telescopic device assembly 25 respectively pushes the concave bearing plate 12 and the concave fixed plate 18, making the moisture content measuring device 17 fully contact with the aggregate. The moisture content measuring device 17 detects the moisture content of the aggregate and outputs the detection result.

[0028] Four groups of L-shaped support legs 3 are provided on the outer side of the working cylinder body 1. Anti-slip plates 4 are provided at the bottom of each group of L-shaped support legs 3, and anti-slip patterns are provided at the bottom of the anti-slip plates 4 to ensure that the equipment remains stable during operation, preventing sliding or tilting. The vibrator control button 43 and the moisture content measuring device control button 26 are both arranged on the inner wall of the concave fixed plate 18, enabling the operator to conveniently control and adjust to ensure the smooth progress of the detection process.

[0029] In a possible implementation manner, the aggregate placement mechanism 11 further includes a positive electrode electromagnet 21 and a negative electrode electromagnet 22. The positive electrode electromagnet 21 is provided at the top of the moisture content measuring device 17, and the negative electrode electromagnet 22 is provided inside the concave fixed plate 18. A filter screen 7 is provided below the partition plate 45. The electric telescopic device assembly 25 includes a first electric telescopic device 27 and a second electric telescopic device 28. The first electric telescopic device 27 is provided above the filter screen 7, and the second electric telescopic device 28 is provided above the concave fixed plate 18; The top of the moisture content measuring device 17 is further provided with a first contact rod 23 and a second contact rod 24. The first contact rod 23 is provided below the moisture content measuring device control button 26, and the second contact rod 24 is provided below the vibrator control button 43. The electric telescopic device assembly 25 and the moisture content measuring device control button 26 are electrically controlled and connected through a transmission wire.

[0030] In the specific application of the embodiments of the present invention, the positive-pole energized electromagnet 21 is located at the top of the moisture content measuring device 17, and the negative-pole energized electromagnet 22 is located inside the concave fixed plate 18. After the aggregate is evenly distributed on the concave bearing plate 12, the positive-pole energized electromagnet 21 and the negative-pole energized electromagnet 22 are energized to generate an electromagnetic field, which helps to improve the detection accuracy of the moisture content measuring device 17 for the moisture content of the aggregate, especially in the case where the aggregate particles are finer or unevenly distributed. The moisture content measuring device 17 is located inside the concave fixed plate 18, and its top is provided with a first contact rod 23 and a second contact rod 24. The first contact rod 23 is connected to the moisture content measuring device control button 26, and the second contact rod 24 is connected to the vibrator control button 43. When the electromagnetic field is stable, the electric telescopic device assembly 25 starts to work. The first electric telescopic device 27 is located above the filter screen 7, and the second electric telescopic device 28 is located above the concave fixed plate 18. The first electric telescopic device 27 and the second electric telescopic device 28 respectively push the concave bearing plate 12 and the concave fixed plate 18 to make the moisture content measuring device 17 fully contact with the aggregate. The moisture content measuring device 17 detects the moisture content of the aggregate and outputs the detection result.

[0031] A filter screen 7 is provided below the partition plate 45 to filter dust or impurities generated during the detection process and ensure the cleanliness of the detection environment.

[0032] In a possible implementation manner, an impurity treatment mechanism 29 is provided on the outer side of the sealing cover 33. The impurity treatment mechanism 29 includes a fan-shaped dust collector 30, a dust suction pump 31, and a flexible connecting pipe 32. The fan-shaped dust collector 30 is provided on the inner wall of the working cylinder 1, the dust suction pump 31 is provided inside the sealing cover 33, one end of the flexible connecting pipe 32 is provided inside the fan-shaped dust collector 30, and the other end of the flexible connecting pipe 32 is provided inside the sealing cover 33.

[0033] In the specific application of the embodiments of the present invention, the fan-shaped dust collector 30 is provided on the inner wall of the working cylinder 1. It adopts a fan-shaped structure, which can cover a large area to ensure that dust and impurities can be effectively collected. The surface of the fan-shaped dust collector 30 is provided with a plurality of tiny pores for capturing dust particles. When the aggregate vibrates or is distributed in the working cylinder 1, the generated dust is concentrated towards the dust collector under the action of air flow. Since the dust particles have inertia and cannot change direction with the air flow, they are captured by the dust collector. The fan-shaped structure of the fan-shaped dust collector 30 optimizes the air flow path to ensure that the dust can be efficiently concentrated inside the dust collector.

[0034] The dust suction pump 31 is arranged inside the sealing cover 33. The dust suction pump 31 generates negative pressure through a high-speed rotating impeller to form an air flow, sucking in and discharging the dust and impurities collected by the fan-shaped dust collector 30. The impeller of the dust suction pump 31 rotates at a high speed driven by an electric motor, converting electrical energy into mechanical energy to drive the air flow movement. The formation of negative pressure forces the dust and impurities to be sucked into the flexible connecting pipe 32 and discharged outside the equipment through the dust suction pump 31. One end of the flexible connecting pipe 32 is arranged inside the fan-shaped dust collector 30, and the other end is arranged inside the sealing cover 33, used to connect the fan-shaped dust collector 30 and the dust suction pump 31 to form a complete dust transmission channel. The flexible connecting pipe 32 uses the air flow to transmit the dust from the fan-shaped dust collector 30 to the dust suction pump 31 to ensure that the dust can be efficiently discharged. The flexibility of the flexible connecting pipe 32 enables it to adapt to the spatial layout inside the equipment while ensuring the smooth transmission of the air flow.

[0035] During the detection process, the vibration and distribution of the aggregate will generate a large amount of dust. The fan-shaped dust collector 30 first uses the principle of air flow and inertial separation to concentrate the dust inside the dust collector. Subsequently, the dust suction pump 31 sucks the dust out of the fan-shaped dust collector 30 through negative pressure adsorption and transmits it to the outside of the equipment through the flexible connecting pipe 32.

[0036] In a possible implementation manner, the lifting and feeding mechanism 34 is arranged outside the working cylinder 1. The lifting and feeding mechanism 34 includes a circular rotating plate 35, a locking rod 36, and an L-shaped telescopic rod 37. The circular rotating plate 35 is arranged on the outer wall of the working cylinder 1. There are two groups of circular rotating plates 35. One side of each of the two groups of circular rotating plates 35 is provided with an L-shaped telescopic rod 37. The other ends of the two L-shaped telescopic rods 37 are arranged on the top of the sealing cover 33. The locking rod 36 is arranged inside the circular rotating plate 35.

[0037] In the specific application of the embodiment of the present invention, the circular rotating plate 35 is arranged on the outer wall of the working cylinder 1, with a total of two groups, located on both sides of the working cylinder 1 respectively. The circular rotating plate 35 is driven by an electric motor to rotate, and its rotation angle and speed can be adjusted through the control system. The rotational movement of the circular rotating plate 35 is based on the principles of torque and angular momentum conservation. The torque output by the electric motor is transmitted to the circular rotating plate 35 through a transmission device, enabling it to rotate smoothly. The rotation of the circular rotating plate 35 not only provides a movement space for the L-shaped telescopic rod 37 but also, through the cooperation of the locking rod 36, ensures that it can be accurately locked at a specific position to avoid deviation due to inertia or external force interference. One side of each of the two groups of circular rotating plates 35 is provided with an L-shaped telescopic rod 37. The other end of the L-shaped telescopic rod 37 is arranged on the top of the sealing cover 33. The L-shaped telescopic rod 37 realizes telescopic movement through hydraulic or electric drive, and its telescopic length and speed can be adjusted according to actual needs. When it is necessary to lift the aggregate, the L-shaped telescopic rod 37 gradually elongates under hydraulic or electric drive, and uses the lever principle to smoothly lift the sealing cover 33 and its connected aggregate limiting frame 10 out of the working cylinder 1.

[0038] The locking rod 36 is arranged inside the circular rotating plate 35 and is used to lock when the circular rotating plate 35 rotates to a specific position, ensuring the stability of the L-shaped telescopic rod 37 during the lifting process. The locking rod 36 is locked by a mechanical buckle or an electromagnetic lock. When the circular rotating plate 35 rotates to the target position, the locking rod 36 automatically snaps into a preset groove or is adsorbed and fixed by electromagnetic force to prevent the circular rotating plate 35 from shifting due to external force or inertia. After the detection is completed, the lifting and pumping mechanism 34 starts to work. First, the circular rotating plate 35 rotates to the preset position under the drive of the motor, and the locking rod 36 is automatically locked to ensure the stability of the circular rotating plate 35. Subsequently, the L-shaped telescopic rod 37 gradually extends under hydraulic or electric drive, and using the lever principle, the sealing cover 33 and the connected aggregate limiting frame 10 are smoothly lifted from the working cylinder 1.

[0039] In a possible implementation manner, a first concave mounting block 38 is provided on one side of the inner wall of the working cylinder 1. A pumping control button 41 is arranged inside the first concave mounting block 38. A first connecting plate 39 is provided on one side of the sealing cover 33, and the first connecting plate 39 is located above the pumping control button 41. A second concave mounting block 44 is provided on the other side of the inner wall of the working cylinder 1. A dust suction pump control button 42 is arranged inside the second concave mounting block 44. A second connecting plate 40 is provided on the other side of the sealing cover 33, and the second connecting plate 40 is located above the dust suction pump control button 42. The dust suction pump control button 42 is electrically connected to the dust suction pump 31 through a conducting wire.

[0040] In the specific application of the embodiment of the present invention, the first concave mounting block 38 is provided on one side of the inner wall of the working cylinder 1, and a pumping control button 41 is arranged inside it. The pumping control button 41 is electrically connected to the pumping pump through a conducting wire, and the pumping pump will automatically start working. The second concave mounting block 44 is provided on the other side of the inner wall of the working cylinder 1, and a dust suction pump control button 42 is arranged inside it. The dust suction pump control button 42 is electrically connected to the dust suction pump 31 through a conducting wire, and the dust suction pump 31 will automatically start working.

[0041] The working of the pumping pump and the dust suction pump are respectively controlled by the pumping control button 41 and the dust suction pump control button 42. When pumping is required, the user presses the pumping control button 41, and the electrical signal is transmitted to the pumping pump through the conducting wire to start the pumping pump to pump the aggregate out of the working cylinder 1. When dust removal is required, the user presses the dust suction pump control button 42, and the electrical signal is transmitted to the dust suction pump 31 through the conducting wire to start the dust suction pump to remove the dust inside the equipment.

[0042] In a possible implementation, the sealing cover 33, the second electric telescopic device 28, the concave fixed plate 18 and the moisture content measuring device 17 form an integrated component from top to bottom. One end of each of the two L-shaped telescopic rods 37 is fixedly connected to the top of the sealing cover 33. A feeding pipe 5 is also provided on the outer side of the working cylinder 1. There are two groups of feeding pipes 5. Impurity removal nets 6 are provided inside both groups of feeding pipes 5. A feeding pump 8 is provided below the filter net 7. The output end of the feeding pump 8 is provided with a one-way feeding pipe 9. The other end of the one-way feeding pipe 9 is arranged inside the aggregate limiting frame 10. The feeding pump 8 is electrically controlled and connected to the feeding pump control button 41 through a conducting wire.

[0043] Four corners inside the concave bearing plate 12 are each provided with a first damping rod 13. First wound buffer spring bodies 14 are provided on the outer walls of the four groups of first damping rods 13. The tops of the four groups of first damping rods 13 are all arranged at the bottom of the aggregate falling buffer plate 16. Four corners inside the concave fixed plate 18 are each provided with a second damping rod 19. Second wound buffer spring bodies 20 are provided on the outer walls of the four groups of second damping rods 19. The tops of the four groups of second damping rods 19 are all arranged at the top of the moisture content measuring device 17.

[0044] In the specific application of the embodiment of the present invention, the sealing cover 33, the second electric telescopic device 28, the concave fixed plate 18 and the moisture content measuring device 17 form an integrated component from top to bottom. The overall lifting of the component is realized through the telescopic movement of the second electric telescopic device 28. The second electric telescopic device 28 is based on the hydraulic or electric drive principle, and converts electrical energy or hydraulic energy into mechanical energy to drive the component to move up and down. When it is necessary to detect the moisture content of the aggregate, the second electric telescopic device 28 extends, and the moisture content measuring device 17 is lowered into the aggregate limiting frame 10 for accurate measurement. After the measurement is completed, the second electric telescopic device 28 contracts, and the component is lifted to the initial position to ensure the safety and convenient operation of the equipment.

[0045] Two groups of feeding pipes 5 are provided on the outer side of the working cylinder 1 for inputting the aggregate into the equipment. Impurity removal nets 6 are provided inside the feeding pipes 5 to filter out large particle impurities in the aggregate, ensuring that the aggregate entering the equipment meets the detection requirements. The aperture of the impurity removal net 6 is based on the particle size distribution of the aggregate, which can effectively intercept impurities and at the same time allow the aggregate to pass through smoothly. The filter net 7 is arranged below the impurity removal net 6 to further filter out fine impurities, ensuring the purity of the aggregate and providing a reliable basis for subsequent detection. A feeding pump 8 is provided below the filter net 7 for conveying the filtered aggregate into the aggregate limiting frame 10. The feeding pump 8 generates negative pressure through a high-speed rotating impeller, sucks in the aggregate and conveys it to the aggregate limiting frame 10 through the one-way feeding pipe 9. The one-way feeding pipe 9 ensures that the aggregate can only flow in one direction, avoiding backflow or blockage. The feeding pump 8 is electrically connected to the feeding pump control button 41 through a conducting wire to automatically start or stop the feeding pump and realize the conveying of the aggregate.

[0046] The aggregate limiting frame 10 is used to accommodate the aggregate to be detected. Inside it, there is a concave bearing plate 12 and an aggregate falling buffer plate 16. The impact force when the aggregate falls is reduced through a buffer mechanism. At the four corners inside the concave bearing plate 12, there are first damping rods 13, and on the outer wall, there is a first wound buffer spring body 14. Based on the damping principle and the principle of elastic potential energy, the impact energy when the aggregate falls is absorbed, reducing vibration and noise. The aggregate falling buffer plate 16 is arranged at the top of the first damping rods 13 to further disperse the impact force of the aggregate, ensuring that the aggregate smoothly falls into the inside of the aggregate limiting frame 10. The moisture content measuring device 17 is arranged below the concave fixing plate 18 and is used to detect the moisture content of the aggregate. At the four corners inside the concave fixing plate 18, there are second damping rods 19, and on the outer wall, there is a second wound buffer spring body 20, which absorbs the vibration generated during the working process of the moisture content measuring device 17 to ensure the accuracy of the measurement result. The top of the second damping rods 19 is arranged at the top of the moisture content measuring device 17, and through its buffering effect, the influence of external vibration on the measuring device is reduced, improving the detection accuracy.
