[0019] 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.

[0020] Please see Figure 1 - Figure 6 The present invention provides the following technical solution: A uniform sand mixer for casting with temperature control function includes a sand mixing box 1, a second valve 6 and a cover plate 7. The top of the feed port at the top of the sand mixing box 1 is rotatably connected to the cover plate 7. The discharge port at the top of the sand mixing box 1 is provided with a second valve 6. A mixing roller structure 2 and a rolling structure 4 are installed from top to bottom inside the sand mixing box 1. Temperature control structures 5 are installed on both the left and right sides of the outside of the sand mixing box 1. The mixing roller structure 2 is connected to a first motor 3. like Figure 1 As shown, the sand mixing box 1 includes a mixing chamber 101, a compaction chamber 102, and a first valve 103. The compaction chamber 102 is located below the mixing chamber 101. The first valve 103 is installed at the discharge port at the bottom of the mixing chamber 101. This structure separates the mixing and compaction operations. After the material is fully mixed in the mixing chamber 101, the first valve 103 is opened to allow the material to enter the compaction chamber 102 for full compaction. Then, the second valve 6 at the bottom of the compaction chamber 102 is opened to discharge the mixed and compacted material. The left and right walls of the compaction chamber 102 are designed to be arc-shaped. This design can guide the material flow, eliminate dead zones, and protect the side walls themselves. like Figure 1 , Figure 3 , Figure 4 - Figure 6 As shown, the mixing roller structure 2 includes a mixing rod 201 and a first gear 202. Two mixing roller structures 2 form a group. One of the first gears 202 is fixedly connected to the output end of the first motor 3. The two first gears 202 mesh and rotate. The mixing rod 201 is fixedly connected to the first gears 202 at the front and rear. The two first gears 202 drive the mixing rod 201 behind it to rotate. The mixing rod 201 is rotatably connected to the mixing chamber 101, so that the two mixing rods 201 mix the material in the mixing chamber 101. Two sets are provided in the mixing chamber 101, one set is located in the upper left corner of the mixing chamber 101, and the other set is located in the lower right corner of the mixing chamber 101, which facilitates the uniform mixing of the material in each position in the mixing chamber 101, thereby improving the mixing uniformity. like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the rolling structure 4 includes a small rolling roller 401, a large rolling roller 402, a small gear 403, a large gear 404, a connecting plate 405, and a gear ring 406. The output end of the second motor 407 is fixedly connected to the small gear 403, which drives the small gear 403 to rotate. Three large gears 404 are meshed on the outside of the small gear 403. The small gear 403 is fixedly connected to the connecting plate 405, and the large gears 404 are rotatably connected to the connecting plate 405. This allows the rotating small gear 403 to drive the three large gears 404 to rotate on their own axis and also to revolve around the small gear 403. At the same time, the large gears 404 are meshed in the gear ring 406, which ensures the stable revolution of the large gears 404. A small gear 403 and a large gear 404 are fixedly connected to the front sides of the small roller 401 and the large roller 402, respectively. The small roller 401 and the large roller 402 are rotatably connected in the crushing chamber 102, so that the small gear 403 drives the small roller 401 to rotate, while the large gear 404 drives the large roller 402 to rotate on its own axis and revolve around the revolution, so that the small roller 401 and the large roller 402 crush the material in the crushing chamber 102 evenly. Through the synergistic effect of the above-mentioned mixing box 1, mixing roller structure 2 and rolling structure 4, the mixing uniformity and rolling uniformity are improved, thereby improving the mixing effect of sand and gravel materials. like Figure 1 - Figure 5 As shown, temperature control structures 5 are installed on both the left and right sides of the outer side of the sand mixing box 1. The temperature control structure 5 includes a mounting shell 501, a cooling plate 502, fins 503, a fan 504, and a dustproof net 505. The cooling plate 502, fins 503, fan 504, and dustproof net 505 are fixedly installed inside the mounting shell 501 from the inside to the outside. When it is necessary to cool down the material in the sand mixing box 1, the current direction is set so that the cold end of the cooling plate 502 is in close contact with the inner wall of the equipment shell and begins to absorb the heat in the sand mixing box 1. The fins 503 are used to receive and conduct heat, and the fan 504 quickly removes the heat, thereby completing the cooling operation. When it is necessary to heat up the material in the mixing box 1, the current direction is set so that the hot end of the cooling chip 502 is in close contact with the inner wall of the equipment shell and begins to release heat into the equipment. This heat comes from the consumed electrical energy and a small amount of heat absorbed from the outside by the other end (cold end). The function of the fins 503 and the fan 504 at this time is to absorb heat from the environment. At the same time, the fan 504 can also prevent the cold end from affecting the heating efficiency of the hot end due to excessive heat accumulation, thus facilitating certain temperature control of the material. Meanwhile, the mixing box 1, mixing rod 201 and rolling roller are made of materials with good thermal conductivity, which facilitates the absorption of heat and cool air, thereby heating and cooling the material to a certain extent. Moreover, the device does not require heating and cooling with large differential values, so it is very suitable to use the cooling plate 502 for temperature control.

[0021] The mounting shell 501 is fixedly installed on the outside of the sand mixing box 1 by plates and screws, so the temperature control structure 5 is easy to disassemble, thus facilitating the maintenance of the temperature control structure 5. The discharge port at the top of the mixing chamber 101 is rotatably connected to the cover plate 7. After the material is poured, the cover plate 7 is closed to reduce the heat or cold air dissipation and reduce energy consumption. Working principle: Open the cover plate 7 and pour in the material. Drive the first motor 3 to make the mixing roller structure 2 run. Drive the second motor 407 to make the two crushing rollers run. At the same time, open the temperature control structure 5 to heat or cool the material according to the actual situation. When the material is mixed evenly, open the first valve 103 to let the material enter the crushing chamber 102 for crushing. After crushing evenly, open the second valve 6 to let the crushed material be discharged. The second valve 6 opens and closes the discharge port of the compaction chamber 102 by moving the baffle left and right with the automatic telescopic rod.

[0022] The above completes a series of operations for the temperature-controlled casting homogenizing sand mixer. Any content not described in detail in this manual is existing technology known to those skilled in the art.
