Detailed Description

Example 1

The concrete mixing device shown in fig. 1-2 comprises a mixing shell 1, wherein the middle part of the top of the mixing shell 1 is rotatably connected with a rotating top cover 2, the rotating top cover 2 is connected with at least two rotating shafts 3 in an axial manner, and gears 4 which are mutually meshed are fixed on the rotating shafts 3; a spiral stirring blade 5 is fixed on the rotating shaft 3; an inner gear ring 6 which is coaxial with the rotary top cover 2 is fixed on the stirring shell 1, wherein one gear 4 is meshed with the inner gear ring 6 through a transition gear 7 which is in shaft connection with the rotary top cover 2; one gear 4 is connected with a rotating device 8; a conical part 9 is formed at the lower part of the stirring shell 1, a discharge hole 10 is formed at the bottom of the conical part 9, and a valve structure is arranged at the discharge hole 10; the top of the agitator housing 1 is formed with a feed port 16.

The valve structure comprises a blocking block 11, wherein the upper surface of the blocking block 11 and the bottom surface of the discharge hole 10 are both arc-shaped; the blocking piece 11 is coupled to the agitator housing 1 by a U-shaped lever 12.

The agitator housing 1 is connected to a support 13. The rotary top cover 2 is rotatably connected with the top of the stirring shell 1 through a bearing 14; oil seals 15 are fixed on the inner side and the outer side of the bearing 14. The rotating device 8 is a motor, and the rotating device 8 is fixedly connected with the rotating top cover 2 through an L-shaped connecting rod 17.

The utility model discloses application method as follows:

put into stirring shell 1 from feed inlet 16 with the concrete material, the motor operation makes 3 antiport of two pivots through the gear, thereby make 5 antiport of the spiral stirring leaf of two syntropy spirals, thereby 5 drive materials of spiral stirring leaf are down, one drives the material and goes upward, in addition the circumference stirring forms three-dimensional stirring and has accelerated the flow of material, thereby quick with concrete mixing, make rotatory top cap 2 itself rotatory through excessive gear 7 simultaneously, thereby the more quick even of stirring. When needing to use the concrete, the transport vechicle directly backs a car and gets into 1 below of stirring casing and promote sprue 11, opens discharge gate 10 and makes the concrete get into the car hopper in, the transport vechicle is driven away after the sufficient concrete dosage for sprue 11 returns the normal position, plugs up discharge gate 10, thereby has realized that discharge gate 10 opens and shuts as required automatically.
