[0002] Concrete, also known as "tóng", is a general term for engineering composite materials that are made of cementitious materials that bind aggregates into a whole. The term concrete usually refers to cement as a cementitious material, sand and stone as aggregates, and water (which may contain admixtures and additives) in a certain proportion, and then mixed to obtain cement concrete, also known as ordinary concrete, which is widely used in civil engineering.

[0003] Slump is a method and index for determining the workability of concrete. On construction sites and in laboratories, slump tests are usually performed to determine the fluidity of the mixture, supplemented by intuitive experience to assess cohesion and water retention. Slump is a quantitative index to measure the degree of its degree, used to determine whether the construction can proceed normally.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] , a concrete multi-quality detection device, by starting motor 1, lifts the lower plate to a half-height position, adjusts the electric telescopic column to make the filling bin fit and contact with the flat plate, and guides the wet concrete into the filling bin through the introduction pipe. Through the shielding and guidance of the guide plate, the wet concrete will slowly flow along the right inner wall of the filling bin to the bottom position of the filling bin. The guidance avoids the splashing of concrete and allows the concrete to be slowly injected and gradually rises inside the filling bin, thereby slowly guiding the concrete to the bottom of the leveling mechanism, thereby helping to simplify the leveling of concrete and improving the linkage ability between the device mechanisms.

[0017] , a concrete multi-quality detection device, starts motor 2 to drive the rotating wheel to rotate, and at the same time drives the cam to rotate with shaft column 2 as the axis through friction. Since one side of the cam is raised, the rotating wheel will be lifted once during the process of the cam rotating one circle, so that the pendulum column will swing with shaft column 1 as the axis, and the connection between connecting column 4 and the ball column will drive the lowering table to descend once, thereby driving the leveling bin to descend to level the concrete through the connection between the square hole and the clamping column, and the clamping between the splint and the notch, and the gas is blown out through the air hole by the lowering of the leveling bin and the squeezing spring 2, so as to level the concrete within the range around the leveling bin, thereby ensuring the flatness of the concrete and improving the accuracy of slump detection.

[0018] , This concrete multi-quality detection device, through the design of the clamping plate and the notch, when the bottom surface of the leveling plate is compacted to the concrete, the stability of the leveling bin is small, and the clamping plate can clamp the notch and move it downward. After the leveling plate compacts the concrete, the stability of the leveling bin is enhanced, and the clamping plate slides downward along the notch, thereby buffering the pressure caused by the descent of the lower pressure platform and avoiding excessive pressure, so that the whole leveling bin is pressed by the lower pressure platform and embedded in the concrete, thereby ensuring the detection quality of the device.

[0019] , This concrete multi-quality detection device, through the design of the splint and the notch, after the lower pressure platform moves down, due to the existence of spring 1, the lower pressure platform will rise and recover. At this time, when the lower pressure platform rises, the splint will be completely engaged with the notch, thereby driving the leveling bin and the leveling plate to move up one end distance, so as to automatically adapt to the height of the concrete that is gradually added and the liquid level rises, thereby improving the adaptability and automatic ability of the device.

[0020] , This concrete multi-quality detection device, after being filled to a certain height, starts motor 1 to quickly release the lower plate to move down to the bottom, so that the bottom of the filling bin loses the resistance of the flat plate, allowing the concrete to flow out from the lower port of the filling bin and re-plasticize above the flat plate. By calculating the height difference between the concrete before and after, the slump of the concrete can be accurately determined, and then the concrete is retained above the flat plate and allowed to dry. At this time, start motor 1 again to move the lower plate up, thereby driving the flat plate to move up, causing the dried concrete to resist the lower teeth, and gradually increasing the pressure between them, thereby detecting the hardness of the concrete, so that the device can detect multiple concrete indicators at the same time, thereby improving the detection strength of the device.

[0021] This concrete multi-quality inspection device, after the inspection is completed, extends the electric telescopic column to lift the inspection mechanism, and then starts the motor to lift the lower plate carrying the flat plate to the top. At this time, the winding belt in contact with the concrete will gradually be wound around the main shaft, thereby completing the removal of the concrete block and the peeling off of the winding belt, improving the automatic peeling ability of the device, avoiding the trouble caused by manual peeling, and improving the use efficiency of the device.

[0047] Working principle:

[0048] Step 1: Start the motor 211 to raise the lower plate 205 to the half-height position, adjust the electric telescopic column 103 to make the filling bin 401 fit in contact with the flat plate 301, and introduce the wet concrete into the filling bin 401 through the introduction pipe 405. The wet concrete will slowly flow into the bottom of the filling bin 401 along the right inner wall of the filling bin 401 through the shielding and guidance of the guide plate 406. The concrete is prevented from splashing and is slowly injected and gradually rises inside the filling bin 401, thereby slowly guiding the concrete to the bottom of the leveling mechanism 6, which helps to simplify the leveling of the concrete and improves the linkage ability between the device mechanisms.

[0049] The second step: start the second motor 516 to drive the rotating wheel 515 to rotate, and at the same time drive the cam 518 to rotate around the second shaft column 517 through friction. Since one side of the cam 518 is raised, the rotating wheel 515 will be lifted once during the process of the cam 518 rotating one circle, so that the pendulum column 513 swings around the first shaft column 512 as the axis, and the connection between the connecting column 4 514 and the ball column 510 drives the pressing table 505 to descend once, thereby driving the leveling bin 601 to descend to level the concrete through the connection between the square hole 506 and the clamping column 605, and the clamping between the splint 507 and the notch 606, and the leveling bin 601 descends to squeeze the spring 2 602 to blow the gas out through the air hole 604, thereby leveling the concrete within the range around the leveling bin 601, thereby ensuring the flatness of the concrete and improving the accuracy of slump detection.

[0050] Step 3: Through the design of the clamp 507 and the notch 606, when the bottom surface of the leveling plate 603 is compacted to the concrete, the stability of the leveling bin 601 is small, and the clamp 507 can clamp the notch 606 and move it downward. After the leveling plate 603 compacts the concrete, the stability of the leveling bin 601 is enhanced, and the clamp 507 slides downward along the notch 606, thereby buffering the pressure caused by the descent of the pressing platform 505 and avoiding excessive pressing, so that the leveling bin 601 is pressed by the pressing platform 505 as a whole and embedded in the concrete, thereby ensuring the detection quality of the device.

[0051] Step 4: Through the design of the clamping plate 507 and the notch 606, after the lower pressing platform 505 moves down, due to the existence of the spring 1 509, the lower pressing platform 505 will rise and recover. At this time, when the lower pressing platform 505 rises, the clamping plate 507 will be completely engaged with the notch 606, thereby driving the leveling bin 601 and the leveling plate 603 to move up a distance, thereby automatically adapting to the height of the concrete that is gradually added and the liquid level rises, thereby improving the adaptability and automatic ability of the device.

[0052] Step 5: After filling to a certain height, by starting the motor 211, the lower plate 205 is quickly released to move down to the bottom, so that the bottom of the filling bin 401 loses the resistance of the flat plate 301, so that the concrete flows out from the lower port of the filling bin 401 and is re-plasticized above the flat plate 301. By calculating the height difference of the concrete before and after, the slump of the concrete can be accurately determined. The concrete is then retained above the flat plate 301 and allowed to dry. At this time, the motor 211 is started again to move the lower plate 205 upward, thereby driving the flat plate 301 to move upward, and the dried concrete is in resistance against the lower teeth 404, and gradually the pressure between them is increased, so as to detect the hardness of the concrete, so that the device can detect multiple concrete indicators at the same time, thereby improving the detection strength of the device.

[0053] Step 6: After the detection is completed, the electric telescopic column 103 is extended to lift the detection mechanism, and then the motor 211 is started to lift the lower plate 205 carrying the flat plate 301 to the top, so that the winding belt 204 in contact with the concrete will gradually be wound around the main shaft 202, thereby completing the removal of the concrete block and the peeling off of the winding belt 204, improving the automatic peeling ability of the device, avoiding the trouble caused by manual peeling, and improving the use efficiency of the device.
