[0023] Example

[0024] The technical solutions in the embodiments of the present utility model will be described clearly and completely below in conjunction with the accompanying drawings.

[0025] like Figure 1-3As shown, a ready-mixed concrete mixing device comprises a mixing box 1, a support frame 2 arranged on both side arms of the mixing box 1 and a support leg 3 arranged below the support frame 2, a conveying box 4 is arranged on the top of the support frame 2 below the mixing box 1, and the mixing box 1 and the conveying box 4 are connected by a conveying pipe 5, a mixing mechanism and a transmission mechanism are arranged inside the mixing box 1, and the transmission mechanism comprises a motor 8 arranged on the top of the mixing box 1, an output shaft of the motor 8 passes through the mixing box 1 to the inside of the mixing box 1 and is connected to a transmission plate 10, and a main The stirring mechanism includes a stirrer 11, which includes a stirring shaft 101 and a four-sided stirring blade 102 arranged at one end of the stirring shaft 101. During the rotation of the four-sided stirring blade 102, since it is always in an inclined state, one side of the four-sided stirring blade 102 will be parallel to the inner wall of the stirring box 1, so as to clean the mixed material adhering to the inner wall of the stirring box 1. The other end of the stirring shaft 101 passes through the transmission plate 10 and is connected to a passive gear 12, and the passive gear 12 is meshed with the active gear 9. A support plate 13 is also provided inside the stirring box 1. Both ends of the support plate 13 are connected to the inner wall of the stirring box 1, and the stirring shaft 101 is inserted in the middle of the support plate 13 and connected to the support plate 13 through a spherical bearing 14. Both sides of the bottom of the support plate 13 are connected to elastic balls 15 through springs. The elastic balls 15 have their own elastic function and are made of flexible materials, so they will not cause damage to the four-sided stirring blade 102.

[0026] A conveying mechanism is provided inside the conveying box 4, a feed port 6 is also provided on the mixing box 1, and a discharge port 7 is provided at the bottom of one side of the conveying box 4. The conveying mechanism includes a motor 16, which is provided on the support frame 2 through a pad 17. The output shaft of the motor 16 passes through the conveying box 4 to the inside thereof and is connected to a rotating shaft 18, on which a spiral blade 19 is provided. The spiral blade 19 can not only stir the mixed material, but also uniformly transfer the mixed material forward. The discharge port 7 is provided at one end of the conveying box 4 away from the motor 16, and the conveying pipe 5 is provided at one side of the top of the conveying box 4 close to the motor 16. The mixed material stirred by the mixing box 1 is put into the starting end of the conveying box 4, so that the mixed material is fully mixed and stirred from one end to the other end of the conveying box 4.

[0027] Working principle: Cement, aggregate and water in a specified proportion are put into the mixing box 1 through the feed port 6, and the starting motor 8 drives the driving gear 9 and the transmission plate 10 to rotate. The transmission plate 10 drives the agitator 11 and rotates around the driving gear 9 through the passive gear 12, thereby driving the four-sided stirring blade 102 to rotate around the inside of the mixing box 1 on the basis of its own rotation to stir, and fully stir the ready-mixed concrete. While stirring, due to the presence of the elastic ball 15, the four-sided stirring blade 102 will hit the elastic ball 15 during the rotation process, thereby vibrating the four-sided stirring blade 102, and shaking off the concrete mixture stuck on the agitator 11. The mixed mixture is transmitted to the conveying box 4 through the conveying pipe 5, and the starting motor 2 16 drives the rotating shaft 18 and the spiral blade 19 to rotate, stir and transmit the mixture, and finally discharge it through the discharge port 7 to complete the mixing.
