DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Example 1

[0022] A mixer capable of adjusting the concrete mix ratio, such as Figure 1-Figure 6 As shown, it includes a support frame 1, a mounting plate 2, a weight sensor 3, a charging barrel 4, a discharging component, a mixing barrel 8, a mixing component, a dustproof component and a control box 14. Three mounting plates 2 are welded at intervals on the top of the support frame 1. Weight sensors 3 are installed on the top of the mounting plates 2. The tops of the weight sensors 3 are connected to the charging barrel 4. An appropriate amount of concrete raw materials can be placed in the charging barrel 4. The weight sensor 3 can detect the weight of the raw materials in the charging barrel 4, so as to control the quantitative discharging of the raw materials. The mixing barrel 8 is connected to the middle part of the support frame 1, and the charging barrel 4 is provided with a discharging component, a mixing component and a dustproof component. A control box 14 is installed on the left front side of the support frame 1, and the weight sensors 3 are electrically connected to the control box 14.

[0023] like Figure 1 and Figure 3 As shown, the discharging assembly includes a discharging pipe 5, a first motor 6 and a valve plate 7. The lower front portion of the mixing barrel 8 is connected to the discharging pipe 5, and the lower portion of the side of the charging barrel 4 close to the mixing barrel 8 is also connected to the discharging pipe 5. The raw materials in the charging barrel 4 can fall into the mixing barrel 8 through the discharging pipe 5. The first motor 6 is bolted symmetrically on the top of the support frame 1, and the first motor 6 is also bolted on the mixing barrel 8. The first motors 6 are electrically connected to the control box 14. The valve plates 7 are rotatably connected in the discharging pipe 5, and the valve plates 7 are connected to the adjacent output shafts of the first motors 6. The valve plates 7 are driven to rotate by the first motor 6 to control the discharging of the raw materials.

[0024] like Figure 4 and Figure 5 As shown, the stirring assembly includes a second motor 9, a third motor 91, a first stirring rod 10 and a second stirring rod 101. The second motor 9 is bolted to the bottom of the stirring barrel 8, and the first stirring rod 10 is rotatably connected to the bottom of the stirring barrel 8. The first stirring rod 10 can stir and mix the raw materials by rotation. The bottom end of the first stirring rod 10 is connected to the output shaft of the second motor 9, and the third motor 91 is bolted to the bottom of the mounting plates 2 on both sides. The second motor 9 and the third motor 91 are electrically connected to the control box 14. The second stirring rod 101 is rotatably connected to the bottom of the loading barrels 4 on both sides, and the second stirring rod 101 is connected to the output shaft of the third motor 91.

[0025] like Figure 1 and Figure 6 As shown, the dust-proof assembly includes a rotating rod 11, a baffle 12 and a counterweight 13. The upper parts of the loading barrels 4 on the left and right sides are rotatably connected to multiple rotating rods 11, and the upper part of the mixing barrel 8 is also rotatably connected to multiple rotating rods 11. The rotating rods 11 are connected to baffles 12, and the rotating rods 11 can drive the baffles 12 to rotate eccentrically. Counterweights 13 are welded to the front ends of the rotating rods 11.

[0026] First, a proper amount of water can be put into the loading barrel 4 at the rear side, and then a proper amount of sand and lime can be put into the loading barrels 4 on the left and right sides respectively. The sand and lime will squeeze the baffle 12 to rotate open, and the baffle 12 can drive the rotating rod 11 to rotate, thereby driving the counterweight 13 to swing upward. After the loading is completed, under the action of gravity, the counterweight 13 will swing downward and reset, and the counterweight 13 can drive the rotating rod 11 to reverse, thereby driving the baffle 12 to reverse and close. The three weight sensors 3 can respectively detect the gravity of water, sand and lime, and then set the program, and then control the first motor 6 at the loading barrel 4 to drive the valve plate 7 to rotate and open through the control box 14, so that the water, sand and lime can respectively fall into the mixing barrel 8 through the three discharge pipes 5. At this time, the baffle 12 on the mixing barrel 8 can be automatically opened, which will not affect the water, sand and lime entering the mixing barrel 8. At the same time, the control box 1 4 controls the third motor 91 to drive the second stirring rod 101 to rotate. The rotation of the second stirring rod 101 can stir the sand and lime respectively, and assist the discharge of the sand and lime. As the raw materials in the charging barrel 4 become less and less, the weight detected by the weight sensor 3 becomes less and less. When the weight sensor 3 detects that the raw material discharge reaches a preset value, the weight sensor 3 sends a signal. After receiving the signal, the control box 14 controls the first motor 6 at the charging barrel 4 to drive the valve plate 7 to reverse and close, so that the raw materials stop discharging. At this time, the control box 14 can control the second motor 9 to drive the first stirring rod 10 to rotate, so that the raw materials in the mixing barrel 8 can be stirred and mixed to obtain concrete. The baffle 12 is in a closed state to prevent dust from flying. Then, the control box 14 controls the first motor 6 at the mixing barrel 8 to drive the valve plate 7 to rotate and open, so that the concrete can be discharged through the discharge pipe 5 and collected manually.
