[0017] The essential features and advantages of the present invention are further described below with reference to examples, but the present invention is not limited to the examples listed.

[0018] like Figures 1 to 4As shown, a concrete feeding device of this embodiment includes a barrel 1, in which a conveying device 2 is provided. The conveying device 2 discharges the material in the barrel 1. The conveying device 2 includes a power source 21 and a shaft 22 connected to the power source 21. The power source 21 drives the shaft 22 to rotate. The shaft 22 is arranged axially along the barrel 1 and has spiral blades 23 on its outer wall. The spiral blades 23 can stir the material and push it to move. A hollow cavity 221 is provided in the shaft 22. A partition 3 is provided in the barrel 1. A feed cavity 24 is provided above the partition 3, and a discharge cavity 25 is provided below the partition 3. The partition 2 is provided with a plurality of through holes 31 that connect the feed cavity 24 and the discharge cavity 25. The shaft 22 is inserted into the partition 3, and the bottom of the shaft 22 extends into the discharge chamber 25. A return port 222 is provided at the bottom of the shaft 22, which communicates with the hollow chamber 221. A discharge port 223 is provided above the shaft 22, which communicates with the feed chamber 24. A plurality of feed ports 241 are provided around the feed chamber 24, and a plurality of discharge ports 251 are provided around the discharge chamber 25. In the above technical solution, material enters the feed chamber 24 through the feed port 241. The rotation of the spiral blade 23 drives the material downward, passes through the through hole 31, enters the discharge chamber 25, and is then discharged through the discharge port 251. When the material needs to be more fully agitated, the discharge port 251 is closed, which can be done with a sealing member such as a cover plate. The material enters the hollow cavity 221 through the return port 222 in the discharge cavity 25 and returns to the feed cavity 24 through the discharge port 223 above the hollow cavity 221, thereby performing a cyclic stirring and conveying. The above technical solution can facilitate the material to be fully stirred and evenly discharged, improving the uniformity of the material and the smoothness of the discharge.

[0019] In this embodiment, a temperature control element 4 is provided within the hollow cavity 221. The temperature control element 4 extends axially from top to bottom along the shaft 22. The temperature control element 4 is capable of generating heat, thereby heating the material within the hollow cavity and controlling the temperature. The temperature control element 4 can be a heating device such as an existing electric heating tube. The power source 21 is disposed at the top of the barrel 1. The power source 21 and the shaft 22 are connected via a gear transmission mechanism 6. The power source 21 can be a motor. The motor and the shaft 22 are driven by an existing gear transmission mechanism, thereby achieving rotation of the shaft 22.

[0020] In this embodiment, the outer wall of the barrel 1 is provided with a jacket 7, which wraps the barrel 1. The jacket 7 is a heating kit that can heat the material in the barrel 1 through the jacket 7. The through hole 31 is a strip hole, and the middle part of the partition wall is a mounting hole 32. The strip hole 31 is arranged around the mounting hole 32. In this embodiment, four strip holes are provided. The mounting hole 31 is used to install the shaft 22. By providing the strip holes, the flow area can be increased. There are multiple barrels, and multiple barrels 1 are arranged at intervals. Different materials can be transported synchronously through multiple barrels. A discharge part 8 is provided below the multiple barrels 1. The discharge part 8 is conical, and a discharge port 81 is provided at the bottom of the discharge part 8. The materials output by the multiple barrels 1 are collected through the discharge part 8 and output from the discharge port 81. The barrel 1 is vertically arranged on the support platform 9, and the upper half of the barrel 1 is exposed above the support platform 9. The material situation in the barrel 1 can be observed by opening an observation window.

[0021] A concrete discharging device in this embodiment can facilitate the discharge of materials after they are fully stirred and evenly mixed, thereby improving the uniformity of the materials and the smoothness of the discharge.
