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.

[0022] Example: Figure 1-6 As shown, this utility model provides a high-efficiency and energy-saving commercial concrete mixing device, including a mixing tank 1 and a waste material tank 2. The bottom end of the mixing tank 1 is fixedly provided with a discharge port 11, and the commercial concrete formed in the mixing tank 1 can be discharged outward through the discharge port 11. The inner cavity of the waste material tank 2 is fixedly provided with a discharge pipe 21. By providing the discharge pipe 21, when the concrete conveying pump is connected to the end of the discharge pipe 21, the concrete collected in the waste material tank 2 can be discharged. A waste material recovery mechanism 3 is provided between the waste material tank 2 and the mixing tank 1. By providing the waste material recovery mechanism 3, the waste material recovery mechanism 3 can recover the commercial concrete remaining in the mixing tank 1. A mixing mechanism 5 is provided on the waste material tank 2. By providing the mixing mechanism 5, the mixing mechanism 5 can mix the commercial concrete collected in the waste material tank 2 to prevent the commercial concrete from solidifying. The residual material recycling mechanism 3 includes a fixed frame 31, on which a fixed plate 32 is fixedly mounted. The open end of the residual material tank 2 is fixedly mounted on the lower end face of the fixed plate 32. Two receiving plates 33 are provided in the inner wall of the fixed plate 32. One receiving plate 33 is vertically aligned with the discharge port 11. By setting two receiving plates 33, when one receiving plate 33 is vertically aligned with the discharge port 11, the residual commercial concrete in the mixing tank 1 can be discharged into one receiving plate 33 through the discharge port 11. The other receiving plate 33 is reserved. The bottom wall of the receiving plate 33 is provided with several No. 1 material holes 34. The bottom wall of the receiving tray 32 is provided with several No. 2 material holes 35. The No. 1 material hole 34 in another receiving tray 33 is vertically aligned with the No. 2 material hole 35. The No. 2 material hole 35 is connected to the inner cavity of the waste material tank 2. By setting the No. 1 material hole 34 and the No. 2 material hole 35, when a receiving tray 33 rotates to the position of the No. 2 material hole 35, the No. 1 material hole 34 and the No. 2 material hole 35 coincide. The commercial concrete in the receiving tray 33 can enter the waste material tank 2 through the No. 1 material hole 34 and the No. 2 material hole 35. The bottom wall of the fixed tray 32 is provided with a discharge chute 36, and one of the receiving trays 33 is vertically aligned with the discharge chute 36. By setting the discharge chute 36, in the initial stage of discharging commercial concrete from the mixing tank 1, the receiving plate 33 is driven to rotate in a circular motion, so that the receiving plate 33 and the discharge chute 36 are in a staggered state. The commercial concrete in the mixing tank 1 is discharged downward into the tank truck through the discharge port 11 and the discharge chute 36. A sealing plate 37 is detachably installed on the lower end face of the fixing plate 32. Several fixing screws 391 are rotatably installed on the sealing plate 37. One end of the fixing screw 391 is rotatably connected to the threaded hole on the lower end face of the fixing plate 32. By setting the fixing screws 391, the sealing plate 37 can be fixed by the fixing screws 391. The sealing plate 37 is fixed below the discharge chute 36 and can be disassembled. A sealing seat 38 is fixedly installed on the upper surface of the sealing plate 37. The sealing seat 38 is set inside the discharge chute 36. A sealing ring 39 is fixedly installed on the outer wall of the sealing seat 38. The outer wall of the sealing ring 39 is in contact with the chute wall of the discharge chute 36. By setting the sealing seat 38 and the sealing ring 39, the sealing seat 38 and the sealing ring 39 can seal the discharge chute 36 (used in the process of residual material recycling; when commercial concrete is discharged into the tank truck, the sealing plate 37 is removed so that the sealing seat 38 and the sealing ring 39 are separated from the discharge chute 36). A transmission rod 4 is rotatably mounted on the lower end face of the fixed disk 32. A half-gear 41 is fixedly mounted on one end of the transmission rod 4. A rotating shaft 42 is rotatably mounted at the axial center of the fixed disk 32. A driven gear 43 is fixedly mounted on one end of the rotating shaft 42. The half-gear 41 and the driven gear 43 are meshed and connected. The gear ratio between the driven gear 43 and the half-gear 41 is 2:1. A rotating rod 44 is fixedly mounted on the other end of the rotating shaft 42. A receiving disk 33 is detachably mounted on one end of the rotating rod 44. Several locking bolts 45 are threaded and rotatably mounted on both ends of the rotating rod 44. One end of the locking bolts 45 is connected to the receiving disk 33. The threaded hole on the outer wall of the material tray 33 is threaded and rotatably connected. By setting the locking bolt 45, the material tray 33 can be installed and disassembled. After disassembly, it is convenient for operators to clean the material tray 33. By driving the transmission rod 4 to rotate, the transmission rod 4 can make the half gear 41 rotate. The half gear 41 can drive the passive gear 43 to rotate 180 degrees. The passive gear 43 can make the two material trays 33 revolve 180 degrees around the circumference through the rotating shaft 42 and the rotating rod 44, so that the two material trays 33 can alternately be vertically aligned with the discharge port 11 to realize the alternating recycling and collection of commercial concrete residue. The mixing mechanism 5 includes a mixing shaft 51, which is rotatably mounted inside the waste material tank 2. Several mixing blades 52 are fixedly mounted on the mixing shaft 51. A servo motor 53 is fixedly mounted at the bottom of the waste material tank 2. A rotating rod 54 is fixedly mounted at the drive output end of the servo motor 53. One end of the rotating rod 54 is fixedly connected to one end of the mixing shaft 51. By starting the servo motor 53, the drive shaft of the servo motor 53 can make the rotating rod 54 rotate. The rotating rod 54 can make the mixing blades 52 rotate through the mixing shaft 51. The mixing blades 52 can mix the commercial concrete collected in the waste material tank 2.

[0023] A toothed pulley 55 is fixedly installed at one end of the rotating rod 54 near the servo motor 53 and at the other end of the transmission rod 4. A transmission toothed belt 56 is installed between the two toothed pulleys 55. By setting the two toothed pulleys 55 and the transmission toothed belt 56, when the rotating rod 54 rotates, the rotating rod 54 can make the transmission rod 4 rotate through the two toothed pulleys 55 and the transmission toothed belt 56.

[0024] Working principle: After the commercial concrete is formed in the mixing tank 1, the operator rotates the two fixed screws 391 to disassemble the sealing plate 37, so that the sealing seat 38 and the sealing ring 39 are separated from the discharge chute 36. At the same time, the servo motor 53 is started. The drive shaft of the servo motor 53 causes the rotating rod 54 to rotate. The rotating rod 54 causes the transmission rod 4 to rotate through the two toothed pulleys 55 and the transmission toothed belt 56. The transmission rod 4 causes the half gear 41 to rotate. The half gear 41 causes the rotating shaft 42 to rotate through the driven gear 43. The rotating shaft 42 causes the two receiving plates 33 to revolve in a circle through the rotating rod 44. In the initial discharge stage of the commercial concrete, the two receiving plates 33 are not vertically aligned with the discharge chute 36. The batch of commercial concrete in the mixing tank 1 is discharged into the tank truck through the discharge port 11 and the discharge chute 36. After the batch of ready-mixed concrete is discharged, the operator assembles the sealing plate 37 on the lower end face of the fixed plate 32. The sealing seat 38 and the sealing ring 39 seal the discharge chute 36, and the two receiving plates 33 are in the initial position, that is, one of the receiving plates 33 is vertically aligned with the discharge port 11. At this time, the ready-mixed concrete remaining in the mixing tank 1 is discharged into one of the receiving plates 33 through the discharge port 11. When one receiving plate 33 is full of ready-mixed concrete, the operator starts the servo motor 53 to drive the two receiving plates 33 to rotate 180 degrees, so that the other receiving plate 33 is vertically aligned with the discharge port 11. At the same time, the multiple No. 1 material holes 34 and multiple No. 2 material holes 35 at the bottom of the receiving plate 33 filled with ready-mixed concrete are vertically aligned. The ready-mixed concrete is discharged into the residual material tank 2 through the multiple No. 1 material holes 34 and multiple No. 2 material holes 35. This cycle is repeated to recycle and collect the ready-mixed concrete remaining in the mixing tank 1.
