It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0024] Please see Figures 1 to 5 An embodiment of the present invention provides an asphalt concrete sample batching device, comprising: a mixing tank 1 and a crushing mechanism 2.

[0025] Please see Figures 1 to 2 The mixing tank 1 is equipped with an inlet pipe 101 and an outlet pipe 102. The inlet pipe 101 is used to add other materials for concrete into the mixing tank 1, thereby facilitating batching. The outlet pipe 102 is used to discharge the batched materials. Multiple support legs 103 are fixedly installed at the bottom of the mixing tank 1 to support the mixing tank 1, preventing it from tilting or shaking, thereby improving the batching and mixing of raw materials.

[0026] Both the feed pipe 101 and the discharge pipe 102 are threaded with threaded plugs 104 to seal the feed pipe 101 and the discharge pipe 102, so that impurities are less likely to enter the mixing tank 1 when the device is not in use and leakage is less likely to occur during the batching process.

[0027] Please see Figures 1 to 5 The crushing mechanism 2 is installed on the mixing tank 1. The crushing mechanism 2 includes a crushing protection frame 201, which improves the conditions for crushing gravel. The crushing protection frame 201 is fixedly installed on the top of the mixing tank 1. A crushing groove is carved inside the crushing protection frame 201. A drive shaft 202 passes through the crushing groove, which drives the rotating support ball 204 and the stirring rod 206 to rotate, achieving the effects of transmission and support. Preferably, the top end of the drive shaft 202 is connected to an external drive device, which drives the drive shaft 202 to rotate.

[0028] Please see Figures 1 to 4A rotating support ball 204 is mounted on the drive shaft 202 to support and drive multiple rotating crushing teeth 205 to rotate, providing conditions for crushing gravel. Multiple evenly distributed rotating crushing teeth 205 are mounted on the rotating support ball 204 to cooperate with the fixed crushing teeth 203 to crush the gravel. Multiple stirring rods 206 are mounted on one end of the drive shaft 202 inside the mixing tank 1 to stir the raw materials. A discharge hole 211 is drilled in the mixing tank 1 to facilitate the discharge of gravel.

[0029] Please see Figures 1 to 4 Multiple fixed crushing teeth 203, which are offset from the rotating crushing teeth 205, are installed on the side wall of the crushing trough. These teeth work together with the rotating crushing teeth 205 to crush the crushed stone, thereby making it difficult for large pieces of crushed stone to enter the mixing tank 1 and improving the quality of the concrete.

[0030] Please see Figures 1 to 3 A baffle plate 207 is installed inside the mixing tank 1, and the drive shaft 202 passes through the baffle plate 207. Multiple sieve holes 208 are drilled on the baffle plate 207 to further filter the crushed stone, effectively preventing large pieces of stone from entering the mixing tank 1. A fixing bolt 209 is installed above the crushing protection frame 201 to fix external equipment and improve the stability of the device. Multiple fixing connecting rods 210 are fixedly connected between the fixing bolt 209 and the crushing protection frame 201 to prevent the fixing bolt 209 from shaking or tilting.

[0031] Please see Figures 1 to 5 A fixed support frame 212 is fixedly installed on the outer wall of the mixing tank 1. A collection box 213 is set inside the fixed support frame 212. A lifting handle 214 is fixed on the collection box 213. The top of the collection box 213 is chamfered to collect the gravel that slides off the shielding inclined plate 207, so that the staff can pour it back into the top of the crushing protection frame 201 for crushing again.

[0032] In actual use, the staff pours the crushed stone into the top of the crushing protection frame 201, and then drives the drive shaft 202 to rotate through the external drive device. The drive shaft 202 drives the rotating support ball 204 and the stirring rod 206 to rotate. The rotation of the rotating support ball 204 also drives multiple rotating crushing teeth 205 to rotate, so that the crushed stone can fall down through the gap between the rotating support ball 204 and the crushing protection frame 201. Moreover, the crushed stone will be crushed during the downward movement to prevent large pieces from falling into the mixing tank 1.

[0033] The crushed gravel will first fall onto the inclined shield 207, then smaller pieces will fall downwards, while larger pieces will slide into the collection box 213, making it convenient for workers to remove them and crush them again. Then, other materials for asphalt concrete will be conveyed into the mixing tank 1 through the feed pipe 101, and then mixed by the mixing rod 206. Finally, it will be discharged out through the discharge pipe 102 for workers to collect.

[0034] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
