Description

Technical Field

[0001] This utility model relates to the technical field of concrete testing, and in particular to the technical field of hardness testing equipment for manufactured sand concrete. Background Technology

[0002] Manufactured sand refers to sand processed by sand making machines and other auxiliary equipment. The finished product is more regular. Manufactured sand is often used in the production of concrete. After the production of manufactured sand concrete is completed, a hardness testing device is needed to test the hardness of the finished manufactured sand concrete. Existing testing equipment mostly uses hydraulic rods to squeeze the concrete until it breaks, thereby obtaining the concrete strength. However, this testing method will cause a large amount of concrete impurities to fall off when the concrete breaks. The fallen impurities are easy to adhere to the pressure plate or remain on the placement plate. If the impurities on the concrete are not cleaned in time, it will lead to data deviation in the next concrete test. Summary of the Invention

[0003] The purpose of this invention is to solve the problems in the prior art by proposing a hardness testing device for manufactured sand concrete. This device can clean and remove residual concrete impurities on the movable bottom tank, effectively preventing deviations in hardness test data caused by concrete impurities, and ensuring accurate hardness test results.

[0004] To achieve the above objectives, this utility model proposes a hardness testing device for manufactured sand concrete, comprising a frame, a testing platform, a movable bottom trough, a pusher baffle, a rotating joint, an electric telescopic push rod, a concrete block, a hydraulic hardness tester, an electric lifting pressure rod, a limit block, a discharge ramp, a rotating brush roller, a lifting mechanical arm, a discharge trough, and a control center. The testing platform is mounted on the upper part of the frame, and the movable bottom trough is slidably mounted on the top of the testing platform. A pusher baffle is mounted on the left side of the movable bottom trough, and an electric telescopic push rod is connected to the left side of the pusher baffle via a rotating joint. The left end of the electric telescopic push rod is fixedly mounted on the frame. A concrete block is placed on the top of the movable bottom trough, and the concrete block's front... A hydraulic hardness tester is installed at the top of the machine frame. Several electrically operated lifting rods are evenly and vertically arranged around the hydraulic hardness tester. The bottom of each electrically operated lifting rod is equipped with a limit block, which is locked onto the top of the concrete block. A discharge ramp is set at the right end of the testing platform, and a rotating brush roller is set above the discharge ramp. The rotating brush roller is installed on the top of the machine frame via a lifting mechanical arm. A discharge chute is detachably installed at the bottom of the discharge ramp. A control center is set on the side of the machine frame. The control center is connected to the electrically operated telescopic push rod, the hydraulic hardness tester, the electrically operated lifting rods, the rotating brush roller, and the lifting mechanical arm.

[0005] Preferably, the bottom of the movable bottom groove is provided with several auxiliary rollers evenly arranged side by side, and guide baffles are symmetrically fixed on the front and rear sides of the test platform, with the movable bottom groove arranged between the guide baffles.

[0006] Preferably, the limiting block has an L-shaped cross-section, is engaged at the top edge of the concrete block, and has a cushioning rubber pad at the contact point between the limiting block and the concrete block.

[0007] Preferably, the rotating brush roller is an active rotating roller, and a rotating motor is connected to the rotating brush roller, which is connected to the control center.

[0008] Preferably, a compressed gas nozzle is provided on the right side of the pusher baffle, facing the right side of the movable bottom groove, and the compressed gas nozzle is connected to a compressed gas source through an elastic telescopic hose.

Through experimental optimization, the concrete block can be fixed in the movable bottom groove on the testing platform by the limit block driven by the electric lifting pressure rod. Then, the hardness of the concrete block is tested by the hydraulic hardness tester. The movable bottom groove, in conjunction with the electric telescopic pusher, pushes the broken concrete block to the discharge ramp for cleaning. The broken concrete block slides into the waste trough under gravity. The remaining concrete impurities on the movable bottom groove are cleaned and removed by the compressed gas nozzle in conjunction with the rotating brush roller. The cleaned movable bottom groove is pulled back to the testing platform by the electric telescopic pusher for continued testing. This effectively prevents deviations in hardness test data caused by concrete impurities, ensuring accurate hardness test results.
