[0002] A concrete slump tester is a specialized device used to measure the slump of concrete mixtures. Its core function is to assess the fluidity, pumpability, and workability of concrete.

[0003] The following problems exist when using testing devices for concrete slump testing: The concrete must be manually placed into the device, and during this process, the concrete mixture, when excessively poured into the shell, often flows along the outer wall of the shell. Because the shell needs to be kept stable for measurement, the operator often needs to step on it. However, this causes the concrete mixture flowing to the outer wall of the shell to stick to the operator's feet. It is also easy for some of the concrete to fall onto the feet during placement. Subsequently, the concrete can seep into the shoes, and the chemical components in the concrete can come into contact with the operator's skin, easily causing skin irritation and posing a safety hazard. Utility Model Content

[0004] The purpose of this invention is to provide a concrete slump testing device, aiming to solve the problem in existing technologies where, due to the need for the housing to remain stable for measurement, operators often need to step on the housing. However, this causes concrete mixture flowing to the outer wall of the housing to stick to the operator's feet. It also easily falls onto the feet during placement. Subsequently, the concrete seeps into the shoe, and the chemical components in the concrete come into contact with the operator's skin, easily causing skin irritation and posing a safety hazard.

A pull rod is connected inside the fixing block, and a spring is sleeved on the surface of the pull rod.

[0006] In a preferred embodiment of the concrete slump testing device of this utility model, the dimensions of the first baffle are the same as those of the second baffle.

[0007] As a preferred embodiment of the concrete slump testing device of this utility model, the first baffle and the second baffle are adapted to be assembled between the baffle block and the fixing block.

[0022] 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.

[0023] Please see Figures 1-5 The present invention provides the following technical solution: a concrete slump testing device, comprising a shell 1, a hopper 2, a slump scale 3 and a tamping rod 4, wherein the hopper 2 is plugged into the shell 1, two handles 5 are symmetrically welded to the surface of the shell 1, two foot pedals 6 are symmetrically welded to the bottom surface of the shell 1, a stop block 7 is welded to the surface of the shell 1, a fixing block 8 is welded to the surface of the shell 1, a first baffle 9 and a second baffle 10 are provided on the outer side of the shell 1, a pull rod 11 is connected inside the fixing block 8, and a spring 12 is sleeved on the surface of the pull rod 11.

[0024] Preferably, the dimensions of the first baffle 9 are the same as those of the second baffle 10.

[0025] In practical use, the first baffle 9 is connected to the gap between the stop block 7 and the fixing block 8, and then the second baffle 10 is connected to the gap between the stop block 7 and the fixing block 8. This ensures that the first baffle 9 and the second baffle 10 form a ring after being connected and cover the top of the housing 1.

[0026] Preferably, the first baffle 9 and the second baffle 10 are fitted together between the stop block 7 and the fixing block 8.

[0027] In practical use, the spacing between the stop block 7 and the fixing block 8 ensures that after the first baffle 9 and the second baffle 10 are connected, the first baffle 9 and the second baffle 10 will not be in a tilted state, and the corresponding ends of the first baffle 9 and the second baffle 10 will be in a close fit. Therefore, it will not affect the shielding of the housing 1.

[0028] Preferably, the cross-section of the pull rod 11 is in the shape of "plus-minus", the pull rod 11 penetrates through the fixed block 8 and extends into the stop block 7, and the pull rod 11 can form an elastic telescopic connection with the fixed block 8 through the spring 12.

[0029] During specific use, the artificial pull rod 11 is pulled downward, and the protruding part on the surface of the pull rod 11 moves downward to start squeezing the spring 12. Then, the spring 12 is squeezed and undergoes a contraction deformation. Subsequently, the pull rod 11 moves out of the inside of the stop block 7 and extends into the inside of the fixed block 8. Then, the downward pull rod 11 is released, and the elastic force of the spring 12 resets the position of the pull rod 11, allowing it to extend back into the inside of the stop block 7, thus facilitating the movement of the pull rod 11.

[0030] Preferably, the first baffle 9 and the second baffle 10 can form a detachable elastic fixed connection with the fixed block 8 and the stop block 7 through the pull rod 11 and the spring 12.

[0031] During specific use, manually operate to pull the pull rod 11 downward to make it move. Then, the spring 12 is squeezed and contracted, and the pull rod 11 is driven to move out of the inside of the stop block 7. Then, the pull rod 1 extends into the inside of the fixed block 8, thus exposing the gap between the stop block 7 and the fixed block 8. During this process, the first baffle 9 and the second baffle 10 can be conveniently taken out. After the first baffle 9 and the second baffle 10 are placed in the gap between the stop block 7 and the fixed block 8, the pull rod 11 is manually released. At this time, the spring 12 uses its elastic force to push the pull rod 11 back into the stop block 7. At the same time, the pull rod 11 passes through the first baffle 9 and the second baffle 10 to achieve the fixation of the two. Such a design greatly facilitates the disassembly and assembly process of the first baffle 9 and the second baffle 10.

[0032] Preferably, a support block 13 is welded to the outer side wall of the housing 1. A bidirectional threaded rod 14 is installed inside the support block 13. The end of the bidirectional threaded rod 14 is connected to a bearing 15. A threaded sleeve 16 is threadedly connected to the surface of the bidirectional threaded rod 14. A clamping block 17 is installed at the end of the threaded sleeve 16.

[0033] During specific use, manually rotate the bidirectional threaded rod 14 to move along the inner ring of the bearing 15. Then, the threaded sleeve 16 moves along the thread on the surface of the bidirectional threaded rod 14. Subsequently, the clamping block 17 can be driven to move. Then, the rammer 4 is placed between the clamping blocks 17, thus facilitating fixation.

[0034] Preferably, the opening size of the threaded sleeve 16 is the same as that of the support block 13. The rammer 4 can form a detachable clamping fixed connection with the clamping block 17 through the bidirectional threaded rod 14.

[0035] In practical use, when the bidirectional threaded rod 14 is manually rotated to move the threaded sleeve 16, the opening size of the bidirectional threaded rod 14 and the support block 13 are the same, which can ensure that the threaded sleeve 16 moves stably along the thread, thus preventing the threaded sleeve 16 from rotating together with the bidirectional threaded rod 14.

[0036] Working principle: The concrete sample is manually divided into three layers, and then the hopper 2 is inserted into the shell 1. The concrete is evenly filled into the shell 1 through the hopper 2. After each layer is tamped a certain number of times using the tamping rod 4, the shell 1 is lifted vertically and evenly. Then, the operator uses the slump gauge 3 to measure the height difference between the height of the shell 1 and the highest point of the slumped concrete sample. This difference is the slump value of the concrete mixture.

[0037] When filling concrete into the housing 1, the first baffle 9 is installed manually, and then the pull rod 11 is pulled downwards. During this process, the pull rod 11 compresses the spring 12, causing it to contract and deform, moving out of the stop block 7 and into the fixing block 8. Next, the first baffle 9 is connected between the stop block 7 and the fixing block 8. Then, the pull rod 11 is released, allowing the spring 12 to return to its original position, pushing the pull rod 11 through the first baffle 9 and reinserting it into the stop block 7, thus fixing the first baffle 9. Subsequently, the second baffle 10 is installed in the same way, so that the first baffle 9 and the second baffle 10 together cover the top of the housing 1. When feeding concrete into the housing 1 through the hopper 2, this design effectively prevents concrete from flowing along the outer wall of the housing 1 or falling onto the operator's feet during filling, thus greatly improving safety and avoiding the problem of concrete coming into contact with the operator's skin and causing skin damage from chemical components.

[0038] After the device is used, the manual person places the tamping rod 4 into the groove of the clamping block 17, and then rotates the bidirectional threaded rod 14 to move it within the inner ring of the bearing 15. The threaded sleeve 16 moves along the threads on the surface of the bidirectional threaded rod 14, causing the clamping blocks 17 to move closer together and fix the tamping rod 4, thus facilitating the carrying of the device.

[0039] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
