[0028] In one embodiment, Figure 1 and Figure 2As shown, a portable pouring concrete mixing device includes a main frame 100 of the device, a mixing cylinder 200 and a feeding component 300 arranged on the main frame 100 of the device, two support seats 500 are arranged at the bottom of the main frame 100 of the device, and the two support seats 500 have foldable roller assemblies 600; the feeding component 300 is arranged at the front end of the main frame 100 of the device, and the top of the feeding component 300 extends to the upper side of the mixing cylinder 200 near the edge, and the feeding component 300 and the outer wall of the mixing cylinder 200 are connected. The material receiving and mixing mechanism 400 is also provided inside the mixing cylinder 200, and the material receiving and mixing mechanism 400 includes a mixing main frame 410, a fan-shaped material receiving assembly 420, a mixing stirring component 430, a spraying unit 440 and an adjusting driving component 450.

The mixing and stirring member 430 is rotatably arranged at the mixing main frame 410 at the center of the mixing cylinder 200 and stirs the concrete in the mixing cylinder 200 in a rotating manner. The fan-shaped receiving component 420 is arranged on the upper side of the mixing cylinder 200 and is located at the semicircular part of the mixing cylinder 200 close to the feeding component 300. The end of the fan-shaped receiving component 420 close to the mixing main frame 410 is connected to the mixing and stirring member 430. The mixing and stirring member 430 can act on the fan-shaped receiving component 420 during the rotation process. The material assembly 420 can crush the concrete thereon; the spraying unit 440 is arranged at the end of the mixing main frame 410 at the center of the mixing cylinder 200, and the spraying unit 440 is used to spray the mixing liquid in the external liquid storage device to the fan-shaped material receiving assembly 420; the adjusting driving component 450 is arranged at the outer end of the mixing main frame 410 at the mixing cylinder 200, the adjusting driving component 450 is connected to the outer wall of the mixing cylinder 200 and the adjusting driving component 450 can drive the mixing main frame 410 to reciprocate along its length direction.

[0029] In the embodiment of the present invention, since the roller assembly 600 on the support seat 500 is foldable, when the roller assembly 600 is in a folded state, the support seat 500 is in contact with the ground and is in a state of supporting the main frame 100 of the equipment, the entire device can maintain a stable state and perform concrete mixing work; when the roller assembly 600 is in an unfolded state, the roller assembly 600 plays a role in supporting the entire equipment, and the entire equipment is movable for easy carrying due to the roller assembly 600; when performing concrete mixing work, the feeding component 300, the mixing and stirring component 430, the spraying unit 440 and the adjusting and driving component 450 are all in a working state, and the mixing staff will mix the concrete to be mixed. The soil is placed at the bottom of the feeding component 300, and the feeding component 300 conveys the concrete to be mixed to the fan-shaped receiving component 420 by rotating upward.

The continuous radial change can effectively increase the mixing area and the mixing method, and further improve the mixing effect; the spraying unit 440 sprays the mixing liquid in the external liquid storage device to the fan-shaped material receiving component 420, and the sprayed mixing liquid contacts the concrete surface of the fan-shaped material receiving component 420 and performs pre-contact, and then the fan-shaped material receiving component 420 crushes the concrete, which can effectively reduce the formation of lumps when the concrete falls into the mixing liquid; wherein, the bottom of the mixing cylinder 200 has a discharge pipe 210 and the discharge pipe 210 extends away from the end of the mixing cylinder 200 to the side of the main frame 100 of the equipment; the poured concrete after mixing is discharged through the discharge pipe 210.

[0031] In one embodiment, Figure 1-Figure 3As shown, the mixing disturbance assembly 433 includes a U-shaped cross bar 4331 and a movable cross bar 4332, one end of the U-shaped cross bar 4331 is fixedly connected to the mixing main shaft and a movable seat 4333 sliding thereon is arranged on the inner side of the U-shaped cross bar 4331, the side of the movable seat 4333 is connected to the inner wall of the U-shaped cross bar 4331 through a mixing spring portion 4334, one end of the movable cross bar 4332 is fixedly connected to the movable seat 4333 and the other end has a push roller 4335 against the inner wall of the mixing cylinder 200; a plurality of mixing rods 4336 are arranged on the movable cross bar 4332 and the U-shaped cross bar 4331; a mixing rod 4336 is arranged on the inner wall of the mixing cylinder 200 There are a plurality of arc-shaped protrusions 220 and the arc-shaped protrusions 220 are located on the travel path of the top roller 4335; in the embodiment of the present invention, the mixing main shaft rotates under the drive of the mixing motor 431, and the plurality of U-shaped cross bars 4331 and the movable cross bar 4332 all rotate with the mixing main shaft.

The gaps between the rods 4336 are equal, thereby stirring the mixing liquid; when the pushing roller 4335 moves to the arc-shaped protrusion 220, the movable cross bar 4332 is gradually retracted into the U-shaped cross bar 4331 under the pushing of the arc-shaped protrusion 220, so that the mixing rods 4336 on the movable cross bar 4332 and the mixing rods 4336 on the U-shaped cross bar 4331 cross each other, effectively changing the gap between the two adjacent mixing rods 4336; therefore, when the mixing disturbance component 433 rotates, the gaps between the mixing rods 4336 on it are changed, effectively acting on the mixing liquid and causing it to be turbulent, and the mixing rods 4336 on the movable cross bar 4332 move radially The mixing liquid is also radially moved so that the mixing liquid can be mixed in multiple directions; wherein, the multiple arc-shaped protrusions 220 on the inner wall of the mixing cylinder 200 are not uniformly arranged and the protruding depths of the arc-shaped protrusions 220 are different. Since the mixing disturbance component 433 outputs a uniform arrangement, when the pushing roller 4335 in one of the mixing disturbance components 433 contacts one of the arc-shaped protrusions 220, the pushing roller 4335 in the other mixing disturbance component 433 may not be released from the remaining arc-shaped protrusions 220, and the pushing roller 4335 in some of the mixing disturbance components 433 may be released from one or several of the arc-shaped protrusions 220, thereby failing to stir the mixing liquid regularly.
