[0001] This utility model relates to the field of materials science testing equipment technology, specifically a mortar abrasion resistance testing machine. Background Technology

[0002] Mortar abrasion resistance testing is an important indicator of whether a material's abrasion resistance meets requirements. Traditional mortar abrasion testing machines involve pouring mortar into the machine's container and completely immersing the sample, which is fixed to a rod connected to a motor, in the mortar. The machine rotates at high speed, causing the sample to undergo sufficient friction within the mortar. However, the high-speed rotation during the test results in unstable movement of the mortar within the container, making it prone to splashing out from the joint between the container and the lid, as well as from holes in the lid. This leads to mortar loss and equipment contamination, affecting the accuracy of the test.

[0003] Therefore, reducing mortar splashing during mortar abrasion resistance testing is a problem that needs to be solved. In response to the above situation, technological innovations are carried out on the basis of existing mortar abrasion resistance testing machines. Utility Model Content

[0020] Please see Figures 1-3A mortar abrasion resistance testing machine includes a mortar container 2. A cover plate 492 is placed on top of the mortar container 2. A first sealing ring 495, a second sealing ring 496, and a retaining wall 494 are fixedly disposed at the bottom of the cover plate 492. The second sealing ring 496 is located outside the first sealing ring 495, and the retaining wall 494 is located outside the second sealing ring 496. The bottom of the first sealing ring 495 is in contact with the top of the mouth of the mortar container 2, and the inner side wall of the second sealing ring 496 is in contact with the outer side wall of the mouth of the mortar container 2. The first sealing ring 495 seals the connection gap between the cover plate 492 and the mortar container 2, and the second sealing ring 496 seals the connection between the retaining wall 494 and the mortar container 2. The cover plate 492 is sealed. A groove is formed at the top of the cover plate 492, and a clearance hole is formed at the bottom of the groove. A sponge ring 493 is fixedly installed inside the groove. A stabilizing component is placed on the outside of the mortar container 2. An upper worktable 4 is placed above the mortar container 2. A limit hole is formed at the top of the upper worktable 4, and a limit shaft 51 is rotatably installed inside the limit hole. The top of the limit shaft 51 passes through the top of the limit hole and is connected to a first pulley 5. A motor 9 is fixedly installed on the rear side of the upper worktable 4. A second pulley 8 is fixedly installed at the top of the output end of the motor 9. A belt 6 is sleeved on the outer wall of the first pulley 5 and the second pulley 8. A rotating rod 3 is fixedly installed at the bottom of the limit shaft 51. The bottom of the rotating rod 3 passes through… The sample 1 is bolted and fixed inside the mortar container 2. The bottom of the rotating rod 3 passes through the groove and clearance hole of the cover plate 492. The sponge ring 493 is located on the outer ring of the rotating rod 3. The second pulley 8 is driven to rotate by the motor 9. The second pulley 8 drives the first pulley 5 to rotate via the belt 6. The first pulley 5 drives the limiting shaft 51 and the rotating rod 3 to rotate. The rotating rod 3 drives the sample 1 to rotate. When the sample 1 rotates, it will come into frictional contact with the mortar in the mortar container 2, thereby conducting an abrasion resistance test on the sample 1. The sponge ring 493 fills the connection gap between the rotating rod 3 and the cover plate 492. The top of the upper workbench 4 has a through-cut first sliding groove. A lifting guide rod 7 is slidably installed in the chute. A through hole is opened through the right side of the inner wall of the first chute. A first threaded hole 71 and a second threaded hole 72 are opened on the right side of the lifting guide rod 7. The first threaded hole 71 is located above the second threaded hole 72. A second bolt 73 is rotatably installed in the through hole. The second bolt 73 is screwed into the second threaded hole 72 and corresponds to the first threaded hole 71. The second bolt 73 is screwed into the second threaded hole 72 to fix the height of the upper worktable 4, so that the sample 1 under the upper worktable 4 can rotate stably in the mortar container 2. The bottom of the lifting guide rod 7 is fixedly installed with the testing machine base 10, and the mortar container 2 is placed on the top of the testing machine base 10.

[0021] The stabilizing component includes a concave frame 41, with a connecting frame 43 fixedly mounted on the top of the concave frame 41. A second sliding groove is formed on the rear side of the inner wall of the concave frame 41, and a bidirectional lead screw 48 is rotatably mounted in the second sliding groove. The bidirectional lead screw 48 passes through the right side of the concave frame 41 and is connected to a handwheel 42. Two sets of internally threaded sliders 44 are evenly screwed onto the outer wall of the bidirectional lead screw 48. A set of connecting blocks 45 is fixedly mounted on the opposite sides of the two sets of internally threaded sliders 44. A second clamping block 47 and a first clamping block 46 are fixedly mounted on the upper and lower sides of the connecting blocks 45, respectively. A third threaded hole is formed through the rear side of the second sliding groove, and a first bolt 49 is screwed into the third threaded hole. An anti-slip pad 491 is fixedly mounted on the front side of the first bolt 49, and the front side of the anti-slip pad 491 is in close contact with the rear side of the bidirectional lead screw 48. The connecting frame 43 is fixedly mounted on the upper working... At the bottom of platform 4, when the upper worktable 4 moves up and down, it will drive the concave frame 41 to move synchronously through the connecting frame 43. The cover plate 492 and the enclosure 494 are located between the two sets of second clamping blocks 47. Turning the handwheel 42 drives the double-acting screw 48 to rotate, which in turn drives the two sets of internal thread sliders 44 to move inward. The internal thread sliders 44 drive the second clamping blocks 47 and the first clamping blocks 46 to move inward through the connecting block 45. The two sets of second clamping blocks 47 clamp and fix the cover plate 492 and the enclosure 494, and the two sets of first clamping blocks 46 clamp and fix the mortar container 2. After tightening the first bolt 49, the anti-slip pad 491 can be driven to fit tightly with the double-acting screw 48, thereby preventing the double-acting screw 48 from rotating and affecting the clamping stability. The mortar container 2 is located between the two sets of first clamping blocks 46.

[0022] Working principle: The second bolt 73 is screwed into the second threaded hole 72 to fix the height of the upper worktable 4, thereby allowing the sample 1 below the upper worktable 4 to rotate stably in the mortar container 2. Turning the handwheel 42 drives the double-ended screw 48 to rotate, which in turn drives the two sets of internal threaded sliders 44 to move inward. The internal threaded sliders 44 drive the second clamping block 47 and the first clamping block 46 to move inward through the connecting block 45. The two sets of second clamping blocks 47 clamp and fix the cover plate 492 and the enclosure 494, and the two sets of first clamping blocks 46 clamp and fix the mortar container 2. After tightening the first bolt 49, the anti-slip pad 491 can be tightly fitted with the double-ended screw 48 to prevent the rotation of the double-ended screw 48 from affecting the clamping. To maintain stability, the motor 9 drives the second pulley 8 to rotate, which in turn drives the first pulley 5 to rotate via the belt 6. The first pulley 5 drives the limiting shaft 51 and the rotating rod 3 to rotate, which in turn drives the sample 1 to rotate. When the sample 1 rotates, it will come into frictional contact with the mortar in the mortar container 2, thus conducting an abrasion resistance test on the sample 1. The sponge ring 493 fills the connection gap between the rotating rod 3 and the cover plate 492, the first sealing ring 495 seals the connection gap between the cover plate 492 and the mortar container 2, and the second sealing ring 496 seals the connection between the enclosure 494 and the mortar container 2. This effectively prevents mortar from flowing out of the connection gaps, thereby reducing mortar waste.

[0023] After the test is completed, loosen the first bolt 49 and then turn the handwheel 42 in the opposite direction to move the first clamping block 46 and the second clamping block 47 outward. Then, after the second bolt 73 is separated from the second threaded hole 72, the upper worktable 4 can be moved upward to move the sample 1 out of the mortar container 2. At this time, the second bolt 73 is aligned with the first threaded hole 71. Then, screw the second bolt 73 into the first threaded hole 71 to fix the upper worktable 4.
