Description

Technical Field

[0001] This utility model relates to the field of coarse aggregate testing technology, specifically to a coarse aggregate abrasion testing device. Background Technology

[0002] Coarse aggregate typically refers to stone or mineral particles with a diameter greater than 5mm. It is a major raw material in building materials such as concrete, mortar, and asphalt mixtures. The quality of coarse aggregate directly affects the strength, durability, and stability of a project. Therefore, its selection, treatment, and testing are all very important. The coarse aggregate abrasion test is used to evaluate the abrasion resistance of coarse aggregate under traffic loads and other external conditions. Its main purpose is to determine the degree of wear of the aggregate under friction and impact to ensure that it will not lead to excessive wear or strength reduction during long-term use, thereby affecting the quality and durability of engineering materials such as concrete and asphalt mixtures. Different countries or regions have different requirements for the abrasion rate of coarse aggregate in their building standards. Generally, aggregates with lower abrasion rates are more suitable for engineering projects with higher requirements.

[0003] In coarse aggregate abrasion tests, the coarse aggregate and the cover plate have a certain weight. In general testing devices, it is not easy to load and unload the coarse aggregate and disassemble and install the cover plate. The test work requires a lot of manpower and time, which greatly reduces work efficiency. At the same time, after the test, the coarse aggregate is not easy to collect and is prone to falling into the gaps of the device, affecting the test results. After the test, a lot of dust is scattered inside the drum of general devices. When unloading, the dust is easy to spread in the air, which can cause certain harm to the health of the workers. In order to solve the above problems, a coarse aggregate abrasion test device is proposed. Utility Model Content

[0004] To address the aforementioned technical problems, a coarse aggregate abrasion testing device is provided. This device solves the problems of the current coarse aggregate abrasion test, where the coarse aggregate and cover plate have a certain weight, making it difficult to load and unload the coarse aggregate and disassemble the cover plate in general testing devices. This results in a large amount of manual labor and time required for the test, significantly reducing work efficiency. Furthermore, after the test, the coarse aggregate is difficult to collect and tends to fall into the gaps in the device, affecting the test results. In general devices, after the test, a large amount of dust is dispersed inside the drum, which easily spreads in the air during unloading, causing certain harm to the health of the workers.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a coarse aggregate abrasion testing device, comprising a working platform, with support frames fixedly connected to both the left and right ends of the upper side of the working platform, rotating rods rotatably connected to the upper inner sides of both sets of support frames, and rollers fixedly connected to the inner sides of the two rotating rods.

A spray pipe is slidably connected to the upper left side of the support frame on the left side. A protective pipe is fixedly connected to the center position on the left side of the inside of the roller. The right end of the spray pipe passes through the left side of the rotating rod on the left side and the left side of the roller and is slidably connected to the inside of the protective pipe. A discharge chute is opened at the front left end of the working platform. The discharge chute is located between the left end of the support frame and the arc-shaped material collection platform.

[0006] Preferably, the upper front end of the cover plate is threaded with a fixing bolt, and threaded holes are provided at both the front and rear ends of the upper side of the roller.

[0007] Preferably, a second push rod is fixedly installed at the middle right side of the left-end support frame. The output end of the second push rod passes through the right side of the support frame and is fixedly connected to a connecting plate. The upper end of the connecting plate is fixedly connected to the left end surface of the spray pipe.

[0008] Preferably, a sealing head is fixedly connected to the right end of the inside of the spray pipe.

[0009] Preferably, a plurality of spray holes are provided through the right end of the surface of the spray pipe.

[0010] Preferably, a drive motor is fixedly installed on the upper right side of the support frame at the right end, and the output end of the drive motor passes through the right side of the support frame and is fixedly connected to the right side of the rotating rod at the right end.

[0011] Preferably, support legs are fixedly connected to the four lower corners of the work platform.

[0012] Compared with the prior art, the advantages of this utility model are as follows: By setting up a chute, slider, handle, fixing bolt, threaded hole, arc-shaped collection platform, push plate, first push rod and unloading chute, this utility model can facilitate the loading and unloading of coarse aggregate and the disassembly and assembly of the cover plate, effectively reducing the labor and time spent on the test work and greatly improving work efficiency.

Sliding sliders 9 are slidably connected inside the two sets of slide grooves 8. Cover plates 10 are fixedly connected to the upper side of the two sliding sliders 9. A handle 11 is fixedly connected to the center of the upper side of the cover plate 10 to facilitate the filling of coarse aggregate. A fixing bolt 12 is threadedly connected to the front end of the upper side of the cover plate 10. Threaded holes 13 are provided at both the front and rear ends of the upper side of the roller 5 to effectively fix the cover plate 10. An arc-shaped collection platform 14 is fixedly connected to the center of the upper side of the working platform 1. A push plate 15 is slidably connected inside the arc-shaped collection platform 14. A first push rod 16 is fixedly installed at the lower left end of the right support frame 3. The output end of the first push rod 16 is fixedly connected to the right side of the push plate 15 to effectively collect coarse aggregate.

[0020] A spray pipe 17 is slidably connected to the upper left side of the left support frame 3. A second push rod 18 is fixedly installed at the middle right side of the left support frame 3. The output end of the second push rod 18 passes through the right side of the support frame 3 and is fixedly connected to a connecting plate 19. The upper end of the connecting plate 19 is fixedly connected to the left end surface of the spray pipe 17. A protective tube 20 is fixedly connected to the center left side of the inside of the roller 5. The right end of the spray pipe 17 passes through the left side of the left rotating rod 4 and the left side of the roller 5 and is slidably connected to the inside of the protective tube 20. The spray pipe 17 is protected to prevent rolling coarse aggregate or steel balls from damaging it. A sealing head 21 is fixedly connected to the right end of the spray pipe 17 to prevent some coarse aggregate from entering the spray pipe 17.
