[0023] 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.

[0024] Reference Figures 1-3This utility model provides an embodiment of a premixed concrete raw material proportioning device, including a mixer box 1, a drive motor 2, a pre-mixed drum 31, a cover frame 32, and a mixing column 33. An adjustment mechanism 4 and an auxiliary mechanism 5 are provided on the mixer box 1. The adjustment mechanism 4 includes an inclined frame 41, which is slidably connected to the outer walls of the left and right sides of the mixer box 1. The inclined frame 41 allows the mixer box 1 to slide obliquely up and down. A motor 42 is fixedly connected to the rear outer wall of the inclined frame 41. The rotation speed of the rotating rod 43 is adjusted by the motor 42. The left and right sides of the inclined frame 41 are... A rotating rod 43 is rotatable via a bearing. An inclined plate 44 is fixedly connected to the outer side wall of the rotating rod 43. Rollers 45 are rotatably connected to the inner walls of the left and right sides of the inclined plate 44 via bearings. By setting the inclined plate 44 and the rollers 45 to cooperate with each other, the rollers 45 roll on the bottom of the mixer box 1, reducing the direct contact between the inclined plate 44 and the bottom of the mixer box 1, which is prone to large friction and high wear rate. A discharge rack 46 is fixedly connected to the bottom outer wall of the mixer box 1. A baffle 47 is slidably connected to the top inner wall of the discharge rack 46, which blocks the opening of the discharge rack 46.

[0025] Reference Figures 2-4 The rotating rod 43 is fixedly connected to the output end of the motor 42 via a coupling. A wear-resistant pad is fixedly connected to the outer side wall of the roller 45. The roller 45 is rotatably connected to the bottom outer wall of the mixer box 1. The discharge rack 46 is connected to the mixer box 1. A pull opening is provided on the front outer wall of the baffle 47. A frosted pad is fixedly connected to the outer side wall of the pull opening. The frosted pad increases the friction of the surface of the baffle 47, reducing the problem of slippage when personnel hold it. The drive motor 2 is fixedly connected to the bottom outer wall of the mixer box 1. The mixing column 33 is fixedly connected to the output end of the drive motor 2 via a coupling. A mixing blade is fixedly connected to the outer side wall of the mixing column 33. The mixing column 33 and the mixing blade are used to mix the raw materials of the concrete mix proportion. The cover frame 32 is snapped into the top inner wall of the mixer box 1. The pre-set cylinder 31 is fixedly connected to the top inner wall of the cover frame 32.

[0026] Reference Figures 3-4The auxiliary mechanism 5 includes an inner groove 51, which is located on the top inner wall of the mixer box 1. A threaded groove 52 is provided on the outer side wall of the cover plate frame 32. The cover plate frame 32 is disassembled by the interaction of the threaded groove 52 and the inner groove 51. A sliding groove 53 is provided on the outer side wall of the cover plate frame 32. A pull plate 54 is slidably connected to the bottom inner wall of the sliding groove 53. The pull plate 54 is used to open and close the bottom of the pre-set cylinder 31. A threaded screw is threaded to the top inner wall of the pre-set cylinder 31. The top outer wall of the threaded tube 55 is fixedly connected to an expansion mask 56. The expansion mask 56 facilitates the pouring of concrete raw materials by personnel and reduces splashing to the outside of the precast cylinder 31. The inner wall of the inner ring of the inner groove 51 is threadedly connected to a threaded groove 52. The pull plate 54 penetrates the bottom inner wall of the precast cylinder 31. The expansion mask 56 is connected to the precast cylinder 31. The top outer wall of the cover plate frame 32 is provided with a directional mark 57. The directional mark 57 indicates the direction of disassembly, assembly and rotation of the cover plate frame 32.

[0027] Working principle: Pre-mixed materials are poured into the mixer box 1 through the pre-mixing cylinder 31. Then, the motor 42 is turned on, causing the rotating rod 43 to rotate. The rotating rod 43 drives the inclined plate 44 to rotate, which in turn drives the roller 45 to contact the bottom outer wall of the mixer box 1, lifting the mixer box 1 to a certain height. After the inclined plate 44 rotates to another angle, the mixer box 1 falls, causing it to shake up and down, simultaneously shaking the pre-mixing cylinder 31 and dislodging some of the material adhering to it. After the mixer box 1 has finished mixing the concrete, the baffle 47 is pulled to open the discharge rack 46, and the mixer box 1 is tilted. Based on the principle of gravity, the concrete... The concrete is discharged from the outlet rack 46. If some of the concrete is not discharged, the mixing column 33 continues to mix by turning on the drive motor 2. At the same time, the motor 42 is turned on to rotate the rotating rod 43. The rotation of the rotating rod 43 drives the eccentric plate 44 to rotate. The rotation of the eccentric plate 44 drives the roller 45, causing the mixer box 1 to shake up and down. This shakes out the residual concrete in the mixer box 1 to avoid waste. At the same time, during pre-filling, since the opening of the pre-filling cylinder 31 is small, the concrete mix material is poured in through the expanding mask 56 to reduce spillage. In addition, during long-term use, the threaded groove 52 is rotated by rotating the cover plate frame 32. The threaded groove 52 rotates and separates from the inner groove 51, making it convenient for personnel to maintain and repair the pre-filling cylinder 31 and the internal components of the mixer box 1.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
