Concrete stirring device

[0011] Such as figure 1 The concrete mixing device shown includes a concrete mixing chamber 1, and a motor chamber 2 arranged below the concrete mixing chamber; and a transmission shaft 3 that penetrates the motor chamber and the concrete mixing chamber; the top of the transmission shaft 3 is mounted on The top of the concrete mixing chamber 1; the bottom of the drive shaft 3 is mounted on the bottom of the motor room 2 through bearings; the motor room 2 and the concrete mixing room 3 are provided with bearings 4 where the drive shaft 3 passes; and the motor room 1 is provided with The power mechanism 5; the output end of the power mechanism 5 is provided with a first pulley 6; the transmission shaft 3 is provided with a second pulley 7 in the motor room; the first pulley 6 and the second pulley 7 pass Belt installation; the outer wall of the drive shaft 3 is provided with a plurality of inclined non-reverse threaded slide grooves 8 in the concrete mixing chamber; the non-reverse threaded slide groove 8 is fitted with a threaded roller 9; the threaded roller 9 is installed Mixing shaft 10; and a concrete buffer box 11 arranged on the side of the concrete mixing chamber 1, wherein the concrete buffer box is provided with a concrete discharge port 12; the concrete mixing chamber 1 is provided with a discharge door 13 on the side of the concrete buffer box 11; A thrust lock 14 is provided at the bottom of the rear side of the discharge door 13.

[0012] The non-reverse threaded sliding groove 8 is inclined downward.

[0013] The non-reverse threaded sliding groove 8 includes a left inclined sliding groove 15 and a right inclined sliding groove 16; the left inclined sliding groove 15 and the right inclined sliding groove 16 are installed alternately.

[0014] The stirring shaft includes a long shaft 17 and a short shaft 18; the long shaft 17 and the short shaft 18 are staggered.

[0015] The top of the concrete mixing chamber 1 is provided with an inlet 19.

[0016] The concrete mixing device of the present invention is matched with a threaded roller and a non-reverse threaded chute, which can mix in one direction. During the mixing process, the material lifted by the lower mixing shaft is sheared and mixed by the upper mixing shaft, and there is no dead zone in the mixing. When mixing starts, close the discharge door. After mixing for a certain period of time, pull off the thrust lock, some of the completed mixing concrete enters the concrete buffer box until it is completely discharged, the mixing is even, and the mixing effect is good.

[0017] The above-mentioned embodiments only describe the preferred embodiments of the present invention, and do not limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by those skilled in the art to the technical solution of the present invention should fall within the protection scope of the present invention. The technical content claimed by the present invention has been all It is stated in the claims.
