Description

Technical Field

[0001] This utility model belongs to the field of building material testing technology, specifically a bridge engineering sand and gravel strength performance testing device. Background Technology

[0002] The strength of aggregates refers to their ability to resist environmental effects such as heat, cold, dryness, and wetness. This performance is generally expressed by a strength value. The strength test involves immersing and drying the aggregates in a saturated sodium sulfate solution. After exposure to heat, cold, dryness, and salt swelling, sulfate crystallizes in the pores of the aggregates, exerting a crystallization expansion force. Weak parts of the aggregates will peel off or detach. The mass loss rate after five immersion and drying cycles is the strength value. An existing patent (publication number: CN219456188U) describes a concrete aggregate strength testing device. While this device includes a pre-treatment structure for washing and drying, it cannot easily and quickly remove the washed aggregates during washing. Furthermore, the drying process is static, resulting in uneven drying, slow drying speed, and low efficiency. Therefore, improvements are needed to address these issues. Utility Model Content

[0015] Depend on Figures 1 to 3 As shown, this utility model includes a base 1, an immersion tank 2 installed on the top of the base 1, an immersion lifting rod installed on the top of the base 1 and on one side of the immersion tank 2, a hook installed on the immersion lifting rod, and a lifting ring test tank installed on the hook. The immersion lifting rod, the hook and the lifting ring test tank have the same function as those in the authorized patent (publication number: CN219456188U).

[0016] The top of the base 1 is provided with a cleaning tank trough 3, and the inside of the cleaning tank trough 3 is provided with a cleaning cylinder 4. Two first connecting shafts 5 are symmetrically installed on the surface of the cleaning cylinder 4. Both first connecting shafts 5 are rotatably connected to the side wall of the cleaning tank trough 3. The inside of the base 1 is provided with a flip adjustment component that is drivenly connected to one of the first connecting shafts 5. The inside of the cleaning cylinder 4 is rotatably installed with a cleaning stirring shaft 6. The bottom of the cleaning cylinder 4 is provided with a first motor 7 connected to the cleaning stirring shaft 6. The top of the base 1 is provided with a drying trough 8, and the inside of the drying trough 8 is rotatably installed with a rotating basket 9. The inside of the base 1 is provided with a second motor 10 connected to the rotating basket 9. The lower part of the drying trough 8 is provided with an electric heating drying wire 11. The bottom of the drying trough 8 is provided with an electric fan 12. The bottom of the drying trough 8 is provided with an air inlet 13 extending to one end of the base 1.

[0017] The top of the cleaning drum 4 is threaded with a lid, and the top of the drying tank 8 is movably latched with a tank lid. Two ventilation screens are installed on the upper part of the tank lid, and a filter screen is installed inside the air inlet 13.

[0018] The tilting adjustment component includes a square inner groove 14 formed inside the base 1. One end of a first connecting shaft 5 extends into the interior of the square inner groove 14 and is fixedly mounted with a gear 15. A slider 16 is slidably mounted inside the square inner groove 14. A toothed plate 17 that meshes with the gear 15 is fixedly mounted on one side of the slider 16. A threaded shaft 18 extending into the interior of the square inner groove 14 and threadedly connected to the slider 16 is rotatably connected to the top of the base 1. A rotating wheel 19 is fixedly mounted on the top of the threaded shaft 18, thereby enabling effective tilting and tilting adjustment of the cleaning drum 4.

[0019] Sand and water are poured into the inside of the cleaning drum 4, and then the lid is installed on the top of the cleaning drum 4. Then the first motor 7 is started to make the cleaning agitator shaft 6 rotate to clean the sand.

[0020] After cleaning, open the bucket lid and rotate the wheel 19 to make the threaded shaft 18 rotate. The rotation of the threaded shaft 18 will cause the slider 16 to move upward on its surface, which will drive the toothed plate 17 to move upward. The upward movement of the toothed plate 17 will drive the gear 15 to rotate, which will drive the first connecting shaft 5 to rotate. The rotation of the first connecting shaft 5 will cause the cleaning drum 4 to rotate and tilt. At this time, the poured sand and gravel can be collected by rotating the basket 9, which can drain water and filter impurities.

[0021] The rotating basket frame 9 includes a basket body 20 and a basket cover 21, which are connected by hinges and a latch. A long retaining plate 23 is fixedly installed on one side of the basket body 20, and a slot box 24 is fixedly installed on the other side. An inverted T-shaped retaining plate 25 is movably inserted into one side of the slot box 24. A spring layer 26 is installed between the end of the inverted T-shaped retaining plate 25 inside the slot box 24 and the basket body 20. A toggle block 27 is fixedly installed on the part; a second connecting shaft 28 is rotatably installed on the upper part of both sides of the drying tank 8, and a long plate 29 is fixedly installed on the opposite end of the two second connecting shafts 28. A square slot is opened on the opposite side of the two long plates 29. A long card plate 23 and an inverted long T-shaped card plate 25 are respectively movably inserted into the two square slots, and the output end of the second motor 10 is connected to one of the second connecting shafts 28, so as to effectively rotate, mix and dry the sand and gravel, effectively improving the drying efficiency and speed.

[0022] The cleaned sand and gravel are placed inside the basket body 20 and basket cover 21 and locked with the buckle. Then, the toggle block 27 is moved to compress the inverted T-shaped card plate 25 against the spring layer 26. Then, the long card plate 23 is inserted into one of the square slots and the inverted T-shaped card plate 25 is aligned with the other square slot. Then, the toggle block 27 is released and the inverted T-shaped card plate 25 is inserted into the other square slot through the spring layer 26.

[0023] Then, the trough cover is closed, and the second motor 10, the electric heating drying wire 11, and the electric blower 12 are turned on simultaneously. The second motor 10, through the second connecting shaft 28, the long plate 29, the square slot, the long card plate 23, and the inverted T-shaped card plate 25, can drive the basket body 20 and the basket cover 21 to rotate, thus mixing the sand and gravel inside. The start of the electric blower 12 will draw outside air into the drying trough 8 and heat the air through the electric heating drying wire 11 to perform hot air drying on the sand and gravel. The mixed sand and gravel can be dried evenly and quickly by the hot air. The dried water vapor and hot air are discharged through the ventilation net, and the trough cover and ventilation net can prevent the hot air from blowing directly on the workers and causing discomfort.
