Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model. Embodiment
[0022] Please refer to Figures 1-3 , the present utility model provides a technical solution:
[0023] A concrete mixing device for road construction, comprising a lifting frame 1. A moving frame 2 is placed inside the lifting frame 1. A connecting frame 3 is rotatably connected inside the moving frame 2. A mixing drum 4 is rotatably connected inside the connecting frame 3. A lifting plate 5 is movably installed on the front of the lifting frame 1. A machine cover 6 is fixedly installed at the bottom of the front end of the lifting plate 5. A base 7 is fixedly installed at the bottom of the machine cover 6. A cover 8 is fixedly installed at the bottom of the base 7. A plurality of rotating shafts 9 are rotatably connected to the top of the base 7. Stirring shafts 10 are fixedly connected to the bottom ends of the plurality of rotating shafts 9.
[0024] First, a first motor 101 is fixedly installed at the top of the lifting frame 1. A threaded rod 102 is rotatably connected to the front of the lifting frame 1, and the top end of the threaded rod 102 is fixedly connected to the driving end of the first motor 101. The lifting plate 5 is threadedly connected to the threaded rod 102 through a connecting sleeve 103. Both the left and right ends of the lifting plate 5 are slidably connected to the lifting frame 1 through sliding rods 104. By driving the threaded rod 102 to rotate through the first motor 101, the lifting plate 5 is driven to move up and down under the connection of the connecting sleeve 103. At the same time, under the connection of the sliding rods 104, the lifting plate 5 can stably drive the machine cover 6 to move up and down. When mixing concrete, first raise the machine cover 6 to raise the plurality of stirring shafts 10. Then, after loading all the materials into the inside of the mixing drum 4, move the moving frame 2 to the lower part of the stirring shafts 10. Then lower the machine cover 6 so that the plurality of stirring shafts 10 extend into the inside of the mixing drum 4, and use the plurality of stirring shafts 10 to mix the materials. At the same time, it is also convenient to pour the concrete after raising the machine cover 6 later.
[0025] Further, a support foot 201 is fixedly connected to the left end of the moving frame 2. Moving wheels 202 are rotatably connected to the front and rear sides of the right end of the moving frame 2. First, lift the support foot 201 and move the moving frame 2 to the lower part of the plurality of stirring shafts 10 through the moving wheels 202. After the movement is completed, support and fix the moving frame 2 through the support foot 201.
[0026] Then, both the left and right ends of the connecting frame 3 are rotatably connected to the moving frame 2 through connecting shafts 301. A runner 302 is fixedly connected to the outside of one set of connecting shafts 301, and a fixed disk 303 is fixedly connected to the inside of the runner 302. A fixed rod 304 is slidably connected to the left side of the moving frame 2. Multiple fixing grooves 305 adapted to the fixed rod 304 are provided on the outside of the fixed disk 303. A spring 306 is sleeved on the outside of the fixed rod 304. When the mixing drum 4 mixes the concrete, under the action of the spring 306, the fixed rod 304 is inserted into the fixing groove 305 inside the fixed disk 303, thereby fixing the connecting shaft 301 and further fixing the connecting frame 3. After the concrete mixing is completed, after raising the mixing shaft 10, first move the moving frame 2 out of the inside of the lifting frame 1, step on the fixed rod 304 downward to release the fixation of the fixed disk 303, and then rotate the runner 302 to drive the connecting frame 3 to rotate, thereby tilting the mixing drum 4 to pour the concrete, which improves the convenience of concrete processing.
[0027] Secondly, a second motor 401 is fixedly installed on the right side of the moving frame 2. A toothed ring 402 is fixedly connected to the outside of the mixing drum 4. The driving end of the second motor 401 is engaged with the toothed ring 402 through a driving gear. When using multiple mixing shafts 10 to mix the concrete, start the second motor 401 to drive the toothed ring 402 to rotate through the driving gear, and control the mixing drum 4 to rotate in the opposite direction of the mixing shaft 10 inside the connecting frame 3, which further improves the mixing effect of the concrete and can improve the mixing efficiency at the same time.
[0028] Finally, a third motor 601 is fixedly installed on the top of the machine cover 6. A driving shaft 602 is rotatably connected to the middle inside the machine cover 6. The top of the driving shaft 602 and the top of the rotating shaft 9 are both rotatably connected to the machine cover 6 through bearings 603, and the top of the driving shaft 602 is fixedly connected to the driving end of the third motor 601. A main gear 604 is fixedly connected to the bottom end of the driving shaft 602. Multiple rotating shafts 9 are engaged with the main gear 604 through driven gears 605 on the outside. When using multiple mixing shafts 10 to mix the concrete, drive the driving shaft 602 to rotate through the third motor 601, drive the driven gears 605 to rotate through multiple main gears 604, thereby driving multiple rotating shafts 9 to rotate together, and then driving multiple mixing shafts 10 to mix the concrete. Multiple mixing shafts 10 are rotatably connected to the base 7 and the cover 8. Multiple mixing rods 1001 are fixedly connected to the outside of multiple mixing shafts 10. When mixing the concrete, the cover 8 is buckled on the top of the mixing drum 4. When the mixing shaft 10 rotates, the concrete is fully mixed through multiple mixing rods 1001, which can not only ensure the uniformity of mixing, but also improve the mixing efficiency.
[0029] In this embodiment, the implementation scenario is specifically as follows: when mixing concrete, first raise the hood 6, thereby raising multiple groups of mixing shafts 10. Then, after loading all the materials into the interior of the mixing drum 4, move the mobile frame 2 to the lower part of the mixing shafts 10. Next, lower the hood 6 so that multiple groups of mixing shafts 10 extend into the interior of the mixing drum 4. Drive the drive shaft 602 to rotate through the third motor 601, and drive the driven gear 605 to rotate through multiple groups of main gears 604, thereby driving multiple groups of rotating shafts 9 to rotate together, and further driving multiple groups of mixing shafts 10 to mix the concrete. When the mixing shafts 10 rotate, the concrete is fully mixed by multiple groups of mixing rods 1001. When using multiple groups of mixing shafts 10 to mix the concrete, start the second motor 401 to drive the toothed ring 402 to rotate through the drive gear, and control the mixing drum 4 to rotate in the inner side of the connecting frame 3 in the direction opposite to that of the mixing shafts 10, further improving the mixing effect of the concrete. After the concrete mixing is completed, raise the mixing shafts 10, then move the mobile frame 2 out of the inner side of the lifting frame 1, step on the fixed rod 304 downward to release the fixation of the fixed disk 303, and then rotate the runner 302 to drive the connecting frame 3 to rotate, thereby tilting the mixing drum 4 to pour the concrete. The whole operation process is simple and convenient. Compared with the existing concrete mixing device, the present utility model can improve the uniformity and mixing efficiency of concrete mixing through the design, and at the same time facilitate pouring, improving the convenience of concrete processing.
