[0001] The utility model relates to the technical field of concrete production, and specifically, to an asphalt mixture mixer for commercial concrete production. Background Art

[0002] Commercial concrete has the characteristics of rich raw materials, low price, and simple production process. At the same time, concrete also has the characteristics of high compressive strength and good durability, and is widely used. Commercial concrete mixtures are mainly composed of asphalt, coarse aggregates, fine aggregates, mineral powder and other additives, so it is necessary to mix the asphalt mixture. Only after sufficient mixing can the asphalt mixture be put into use.

[0003] At present, after the existing asphalt mixture is stirred and poured out, most of the pouring is to rotate the mixing tank and pour it out from the feeding port. However, it is necessary for workers to fix the mixing tank during discharging, which is time-consuming and laborious. For this reason, the utility model provides an asphalt mixture mixer for commercial concrete production. Summary of the Utility Model

[0004] The utility model provides an asphalt mixture mixer for commercial concrete production to solve the problem that after the existing asphalt mixture is stirred and poured out, most of the pouring is to rotate the mixing tank and pour it out from the feeding port, but it is necessary for workers to fix the mixing tank during discharging, which is time-consuming and laborious as mentioned in the above background art.

[0005] The technical solution of the utility model is as follows:

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts fall within the scope of protection of the present utility model.

[0026] Embodiment 1

[0027] As Figures 1 to 5 shown, this embodiment proposes an asphalt mixture mixer for commercial concrete production, including a bottom plate 1 and a mixing tank 2. One side of the upper end surface of the bottom plate 1 is fixedly installed with an L-shaped bracket 3. One side of the top of the mixing tank 2 is fixedly communicated with a feed inlet 4. One side of the bottom of the mixing tank 2 is fixedly communicated with a discharge outlet 5. Sealing plates are clamped on both the feed inlet 4 and the discharge outlet 5. A discharging assembly 100 is installed on the L-shaped bracket 3, and a mixing assembly 200 is installed inside the mixing tank 2;

[0028] The material discharging assembly 100 includes a driving motor 101 fixedly installed on the top of the L-shaped bracket 3. The input end of the driving motor 101 is connected to a power source through an external cable. The output end of the driving motor 101 penetrates through the L-shaped bracket 3 to the bottom through a bearing and fixedly installs a bidirectional screw 102. One side of the bottom of the L-shaped bracket 3 fixedly installs a support plate 103. The bottom end of the bidirectional screw 102 is rotatably connected to the upper end surface of the support plate 103. The outer surfaces of both ends of the bidirectional screw 102 are threadedly connected with connecting plates 104. One side of each of the two connecting plates 104 fixedly installs a guide rod 105. The two guide rods 105 are arranged left and right. Through holes 106 for the guide rods 105 to slide through are opened on both of the two connecting plates 104. The guide rods 105 are matched with the through holes 106. Fixed blocks 107 are fixedly installed on the outer surfaces of both of the two guide rods 105. One side of each of the two fixed blocks 107 is in contact with the side wall of the L-shaped bracket 3. One end of each of the two fixed blocks 107 rotatably connects a connecting column 108. A transmission rod 109 is fixedly installed on the outer surface of the connecting column 108. One side of the mixing tank 2 fixedly installs a mounting block 110. The two sides of the mounting block 110 are symmetrically rotatably connected with connecting columns 111. One end of each of the two connecting columns 111 is fixedly installed on one side of the bottom end of the transmission rod 109;

[0029] Through the arranged material discharging assembly 100, the mixed material in the mixing tank 2 can be automatically discharged. When it is necessary to automatically discharge the mixed material in the mixing tank 2, start the driving motor 101 to drive the bidirectional screw 102 to rotate. During the rotation of the bidirectional screw 102, the two connecting plates 104 are pushed to move relatively, thereby driving the fixed blocks 107 on the guide rods 105 to move relatively. Then, through the mutual cooperation among the connecting column 108, the transmission rod 109 and the connecting column 111, the mixing tank 2 is driven to be inclined. Then, open the sealing plate at the bottom of the discharge port 5, and the mixed material in the mixing tank 2 can be automatically discharged.

[0030] Embodiment 2

[0031] As Figures 1 to 5As shown, based on the same concept as in the above-mentioned Embodiment 1, this embodiment also proposes that the mixing assembly 200 includes a protective cover 201 fixedly installed on one side of the mixing tank 2. A second driving motor 202 is fixedly installed on one side of the protective cover 201. The input end of the second driving motor 202 is connected to a power source through an external cable. The output end of the second driving motor 202 passes through the protective cover 201 through a bearing and is fixedly installed with a driving gear 203. A number of driven gears 204 are meshed with the outside of the driving gear 203 at equal distances. One ends of the driving gear 203 and the number of driven gears 204 are fixedly installed with rotating rods 205. One ends of the number of rotating rods 205 pass through the mixing tank 2 through bearings and are rotatably connected to the side wall of the mixing tank 2. A number of stirring rods 206 are fixedly installed on the outer surfaces of the number of rotating rods 205. The number of stirring rods 206 are arranged in a crosswise manner. A scraper 207 is fixedly installed on the rotating rod 205 at one end of the number of driven gears 204. The scraper 207 can scrape the inner wall of the mixing tank 2, which can effectively prevent the mixture from sticking to the inner wall of the mixing tank 2. One side of the scraper 207 is in contact with the side wall of the mixing tank 2. Through the arranged mixing assembly 200, the asphalt mixture can be effectively and fully stirred. When it is necessary to fully stir the asphalt mixture, by starting the second driving motor 202 to drive the driving gear 203 to rotate, the driving gear 203 drives the number of driven gears 204 to rotate, thereby driving the stirring rods 206 at one end of the number of driven gears 204 to rotate relative to the stirring rod 206 at one end of the driving gear 203, so as to fully stir the asphalt mixture.

[0032] During operation, first, the asphalt mixture is put into the mixing tank 2 through the feeding port 4, then the sealing plate is closed, and then the second driving motor 202 is started to drive the driving gear 203 to rotate. The driving gear 203 drives the number of driven gears 204 to rotate, thereby driving the stirring rods 206 at one end of the number of driven gears 204 to rotate relative to the stirring rod 206 at one end of the driving gear 203, so as to fully stir the asphalt mixture. While the rotating rod 205 is rotating, it drives the scraper 207 to scrape the inner wall of the mixing tank 2, which can effectively prevent the mixture from sticking to the inner wall of the mixing tank 2. When it is necessary to unload the material, by starting the first driving motor 101 to drive the bidirectional screw 102 to rotate, during the rotation of the bidirectional screw 102, it thus pushes the two connecting plates 104 to move relatively, thereby driving the fixing blocks 107 on the guide rods 105 to move relatively. Then, through the mutual cooperation among the first connecting column 108, the transmission rod 109, and the second connecting column 111, the mixing tank 2 is driven to be inclined, and then the sealing plate at the bottom of the discharge port 5 is opened, so as to automatically pour out the mixture in the mixing tank 2.

[0033] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
