Description

Technical Field

[0001] The utility model relates to the technical field of concrete, and specifically relates to a concrete blanking device. Background Art

[0002] Concrete, abbreviated as "砼", refers to the general term for engineering composite materials that are cemented into a whole by cementitious materials. Usually, the term "concrete" refers to cement concrete, also known as ordinary concrete, which is made of cement as the cementitious material, sand and stone as aggregates, and is mixed with water (which may contain admixtures and additives) in a certain proportion and stirred. It is widely used in civil engineering.

[0003] At present, although the existing concrete blanking devices are equipped with stirring mechanisms, the stirring and discharging actions lack linkage design, resulting in additional operations required for blanking after stirring, with low efficiency. Therefore, a concrete blanking device is provided. Content of the Utility Model

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-2This utility model provides a technical solution: a concrete feeding device, comprising: a frame 1 as an integral support structure, fixing other components; a hopper 2 disposed on the frame 1 for holding concrete; a lifting frame 3 disposed on the frame 1 and located on one side of the hopper 2, realizing the lifting linkage between the mixing component 4 and the inclined discharge channel 6; the mixing component 4 disposed on the top of the lifting frame 3 for mixing the concrete in the hopper 2; a spiral scraper 5 disposed on the mixing component 4 and adapted to the inner wall of the hopper 2, during discharge, the spiral scraper 5 adheres to the inner wall of the hopper 2 to scrape off the adhering concrete and avoid residue; the inclined discharge channel 6 disposed at the bottom of the lifting frame 3 and adapted to the discharge end of the hopper 2; wherein, in the initial state, the inclined discharge channel 6 adheres to the discharge end of the hopper 2 to close the hopper 2, and the inclined discharge channel 6... The discharge channel 6 is tightly fitted with the discharge end of the hopper 2, forming a closed structure to prevent concrete leakage. At this time, the lifting frame 3 is in a high position, and the spiral scraper 5 on the mixing component 4 is not in contact with the inner wall of the hopper 2, and can mix the concrete. After mixing, the lifting frame 3 descends, causing the spiral scraper 5 on the mixing component 4 to fit against the inner wall of the hopper 2. During the mixing process of the mixing component 4, the spiral scraper 5 further cleans up the residual concrete, and at the same time, it causes the inclined discharge channel 6 to disengage from the discharge end of the hopper 2 and open the hopper 2. Through the linkage design of the lifting frame 3, the mixing and discharge actions are completed simultaneously without additional operation, significantly shortening the process time and reducing the need for manual intervention. After mixing, the lowering of the lifting frame 3 automatically triggers the opening of the inclined discharge channel 6, reducing equipment downtime and improving overall construction efficiency.

[0023] Specifically, the lifting frame 3 includes a screw module 31 mounted on the frame 1. The screw module 31 can precisely control the displacement of the C-shaped frame 32 to ensure the fit between the mixing component 4 and the inner wall of the hopper 2. The moving end of the screw module 31 is equipped with the C-shaped frame 32. The mixing component 4 is fixed at the top of the C-shaped frame 32, and the bottom is connected to the inclined discharge channel 6. The frame 1 is equipped with a guide rod 33 that passes through the C-shaped frame 32. The guide rod 33 limits the frame to move smoothly in the vertical direction. When the screw module 31 is activated, the C-shaped frame 32 is driven to descend. The C-shaped frame 32 slides down vertically along the guide rod 33, simultaneously driving the mixing component 4 and the inclined discharge channel 6 to move synchronously. The spiral scraper 5 of the mixing component 4 fits against the inner wall of the hopper to complete the cleaning after mixing. The inclined discharge channel 6 disengages from the discharge end of the hopper 2 and opens the discharge port, realizing the linkage design of the lifting frame 3 driving the mixing component 4 and the inclined discharge channel 6.

[0024] Specifically, the mixing assembly 4 includes a drive motor 41 mounted on top of the lifting frame 3. This drive motor can be a three-phase asynchronous motor or a servo motor, providing stable rotational power. The drive motor 41 is equipped with a protective shell 42 to prevent dust and concrete particles from entering the motor. The drive end of the drive motor 41 extends into the hopper 2 and is equipped with a rotating rod 43. The upper side wall of the rotating rod 43 is equipped with several evenly distributed mixing rods 44. The spiral scraper 5 is fixedly connected to the ends of the mixing rods 44. In actual use, the drive motor 41 is started to drive the rotating rod 43 to rotate. The rotating rod 43 drives the mixing rods 44 and the spiral scraper 5 to rotate synchronously, thereby mixing the concrete in the hopper 2 and effectively preventing the concrete from solidifying in the hopper 2.

[0025] Specifically, the lower end of the rotating rod 43 is equipped with a spiral conveying blade 45. The mixed concrete is conveyed to the inclined discharge channel 6 by the propulsion of the spiral conveying blade 45, so as to realize the complete discharge of concrete in the hopper 2.

[0026] Specifically, the discharge end of the hopper 2 is set to be an inclined surface that is compatible with the inclined discharge channel 6. The inclined surface of the discharge end of the hopper 2 is completely consistent with the inclined discharge channel 6, ensuring that the two fit tightly together in the initial state to form a seal.

[0027] Working principle: In the initial state of operation, the lifting frame 3 is kept at a high position. The drive motor 41 is started to drive the rotating rod 43 and the stirring rod 44 to rotate and stir. During the discharge stage, the lifting frame 3 descends and the inclined discharge channel 6 opens. The concrete is efficiently discharged under the action of gravity and the spiral conveying blade 45. After the discharge is completed, the lifting frame 3 rises back to the high position and the inclined discharge channel 6 re-fits the discharge end of the hopper 2, ready for the next cycle.
