[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Many specific details are set forth in the following description to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.
[0023] Please see Figures 1 to 2 As shown, a semi-open feeding hopper is connected to the discharge port (not shown) of a mixing device to adapt to actual production feeding needs and help improve production efficiency. Specifically, the semi-open feeding hopper includes a temporary storage hopper 1, a discharge assembly 2, and a power unit 3. The top and bottom of the temporary storage hopper 1 are respectively provided with a feed inlet 11 and a discharge outlet 12. The feed inlet 11 of the temporary storage hopper 1 covers the outside of the discharge port of the mixing device and is fixedly connected to the mixing device. The discharge assembly 2 is slidably disposed at the bottom of the discharge outlet 12 for opening or closing the discharge outlet 12. The power unit 3 is disposed on one side of the discharge outlet 12 for driving the discharge assembly 2 to move towards or away from the discharge outlet 12, that is, for driving the discharge assembly 2 to open or close the discharge outlet 12.
[0024] During implementation, after the mixing equipment finishes mixing, the concrete enters the temporary storage hopper 1 from the discharge port of the mixing equipment. At this time, the discharge assembly 2 is in its initial position (covering the bottom of the discharge port 12) to prevent the concrete from falling. When it is necessary to discharge, the power unit 3 is started, driving the discharge assembly 2 to move, so that the concrete flows out from the discharge port 12.
[0025] In this embodiment, slide rails 21 are fixedly provided on opposite sides of the discharge port 12. The unloading assembly 2 includes a baffle 22 and two U-shaped plates 23 spaced apart. The baffle 22 is located at the bottom end of the discharge port 12. The bottom surfaces of the interiors of the two U-shaped plates 23 are fixedly connected to the bottom surfaces of the baffle 22. The two top ends of each U-shaped plate 23 extend to the outside of the corresponding slide rail 21 and are rotatably provided with rollers 24. Each roller 24 is rolled in the corresponding slide rail 21. One end of the power unit 3 is fixedly connected to the baffle 22.
[0026] During implementation, the power unit 3 drives the baffle 22 to move. Since the baffle 22 is fixedly connected to the U-shaped plate 23, the roller 24 at the top of the U-shaped plate 23 rolls within the slide rail 21, which facilitates the power unit 3 to guide the baffle 22 to move stably along the slide rail 21, thereby opening or closing the unloading assembly 2 and controlling the discharge of concrete. By adopting the design of the slide rail 21 and the roller 24, the movement of the unloading assembly 2 is made more stable and smooth, reducing friction and energy loss, while also improving the accuracy of the movement of the unloading assembly 2 and ensuring the uniformity of the discharge.
[0027] In this embodiment, a fixing plate 25 is fixedly installed at the end of the slide 21 away from the discharge port 12. The power unit 3 includes a telescopic cylinder 31 fixedly installed on one side of the baffle 22. The output end of the telescopic cylinder 31 is fixedly connected to one side of the baffle 22. When material needs to be discharged, the output end of the telescopic cylinder 31 retracts to pull the baffle 22 to move, thereby opening the unloading assembly 2 and allowing the concrete to begin falling. When material discharge needs to be stopped, the output end of the telescopic cylinder 31 extends to move the baffle 22 away from the telescopic cylinder 31, thereby closing the unloading assembly 2 and stopping the concrete from falling.
[0028] In this embodiment, the baffle 22 has a guide groove 221 inside that connects to the outside. A guide rod 32 is fixedly mounted on the fixed plate 25 corresponding to the guide groove 221, with one end of the guide rod 32 slidably disposed within the guide groove 221 away from the fixed plate 25. During the movement of the baffle 22, the guide rod 32 slides within the guide groove 221, guiding the movement of the baffle 22 and ensuring that the baffle 22 always moves in a predetermined direction. This prevents the baffle 22 from shifting or shaking during movement, ensuring the normal operation of the unloading assembly 2 and improving the accuracy and reliability of material discharge. Preferably, there are two guide grooves 221 and two guide rods 32, located on the radial sides of the telescopic cylinder 31, respectively. This further improves the stability and balance of the baffle 22's movement, reducing equipment malfunctions and uneven material discharge caused by uneven force distribution.
[0029] In this embodiment, a shielding component 4 is fixedly installed on the side of the discharge port 12 away from the power unit 3. This is to prevent concrete from splashing from one side of the discharge port 12 during the concrete falling process when the unloading component 2 is opened, thus avoiding losses. In other words, by setting the shielding component 4, it is ensured that all concrete falls to the designated position in a predetermined direction. Specifically, the shielding component 4 includes a curtain 41, a connecting plate 42, and multiple bolts 43. The connecting plate 42 is located at the top of the curtain 41 and on the side of the curtain 41 away from the discharge port 12. The multiple bolts 43 are evenly arranged along the length of the connecting plate 42, and one end of each bolt passes through the connecting plate 42 and the curtain 41 in sequence before being screwed to the side wall of the discharge port 12.
[0030] When installing the shielding assembly 4, the connecting plate 42 is placed on top of the curtain 41. Bolts 43 are then passed through the connecting plate 42 and the curtain 41 in sequence and screwed onto the side wall of the discharge port 12 to complete the installation. When maintenance or replacement of the shielding assembly 4 is required, it can be removed simply by unscrewing the bolts 43, facilitating maintenance and replacement. Preferably, the curtain 41 is made of any one of rubber, polyurethane, or high-density polyethylene. These materials have good flexibility, wear resistance, and corrosion resistance, effectively adapting to the friction and impact during concrete discharge, extending the service life of the shielding assembly 4, and reducing equipment maintenance costs.
[0031] In a specific implementation of this utility model, after the mixing equipment completes mixing, the concrete enters the temporary storage hopper 1 of the discharge hopper from the discharge port of the mixing equipment. At this time, the telescopic cylinder 31 is in its initial state, the discharge assembly 2 is closed, and the concrete cannot fall. When discharge is required, the output end of the telescopic cylinder 31 retracts, pulling the baffle 22 to move. The baffle 22 drives the U-shaped plate 23 to move, and the roller 24 at the top of the U-shaped plate 23 rolls in the slide 21. At the same time, the guide rod 32 slides in the guide groove 221 to ensure the smooth movement of the baffle 22. As the baffle 22 moves, the discharge assembly 2 gradually opens, and the concrete flows out from the discharge port 12. During the discharge process, the curtain 41 of the shielding assembly 4 can prevent concrete from splashing. When it is necessary to stop the discharge, the output end of the telescopic cylinder 31 extends, pushing the baffle 22 to move in the opposite direction, causing the discharge assembly 2 to close and stopping the concrete from falling.

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
