The technical solutions in the present application will be described in further detail below with reference to the accompanying drawings.

The embodiment of the application discloses concrete mixing plant discharge apparatus. Referring to fig. 1 and 2, a discharging device of a concrete mixing plant comprises a discharging hopper 1, wherein the discharging hopper 1 is communicated with a mixer and used for discharging concrete in the mixer to a transport vehicle. The top of hopper 1 is the feed end, and the bottom is the discharge end, by feed end to discharge end, the cross-sectional area of hopper 1 reduces gradually. A rotating shaft 21 is rotatably arranged at the bottom end of the discharging hopper 1, and the rotating shaft 21 is positioned in the discharging hopper 1. The material smashing rods 22 are uniformly distributed on the rotating shaft 21, and the material smashing rods 22 are radially arranged on the rotating shaft 21. The discharging hopper 1 is provided with a driving component for driving the rotating shaft 21 to rotate.

The driving assembly drives the rotating shaft 21 to rotate, and the material smashing rod 22 on the rotating shaft 21 moves along with the rotating shaft 21. The material smashing rod 22 can break the arch of the concrete in the discharging hopper 1 in the rotating process, so that the concrete can fall down from the discharging hopper 1 more conveniently. The material smashing rod 22 can break and stir the concrete in the rotating process, so that the concrete is not easy to stick together to block the discharging hopper 1.

Referring to fig. 1 and 2, the driving assembly includes a speed reducer 31 fixedly disposed on the discharging hopper 1 and a motor 32 disposed on the speed reducer 31. The output end of the motor 32 is connected with the input end of the speed reducer 31, and the output end of the speed reducer 31 is connected with the rotating shaft 21. The speed reducer 31 reduces the rotating speed output by the motor 32, increases the torque output by the motor 32, and is beneficial to the rotating shaft 21 to drive the ramming material rod 22 to rotate in the concrete.

Referring to fig. 2 and 3, a connecting plate 23 is fixedly disposed at an end of the tamper rod 22 away from the rotating shaft 21, a connecting plate 23 is fixedly disposed at a side of the connecting plate 23 away from the tamper rod 22, and the connecting plate 23 and the tamper rod 22 are located on the same plane. The side of the connecting plate 23 far away from the material smashing rod 22 is hinged with a first scraper 24. An elastic member is arranged between the connecting plate 23 and the first scraper 24, and when the elastic member is in a non-deformation state, the connecting plate 23 and the first scraper 24 are in the same plane.

After the blanking is stopped, the rotating shaft 21 continues to rotate, and the residual concrete on the discharging hopper 1 is cleaned. During the rotation of the rotating shaft 21, the first scraper 24 will abut against the inner wall of the discharging hopper 1, so that the elastic member is deformed. Meanwhile, the first scraper 24 scrapes off the concrete attached to the inner wall of the discharge hopper 1 in the process of moving along with the tamping rod 22, so that the concrete retained on the inner wall of the discharge hopper 1 is effectively reduced, and the smoothness of subsequent blanking is ensured. The viscidity of concrete is great, and the clearance difficulty after solidifying clears up, clears up remaining concrete immediately after the unloading is accomplished, can effectively reduce the concrete and solidify on hopper 1 and block up hopper 1 gradually.

One right-angle side of the reinforcing rib 26 is fixedly connected with the material smashing rod 22, and the other right-angle side of the reinforcing rib is fixedly connected with the connecting plate 23. The reinforcing ribs 26 can enhance the connection strength between the tamping bar 22 and the connecting plate 23, so that the tamping bar 22 and the connecting plate 23 are not easy to bend.

Referring to fig. 2, a second scraper 27 is fixedly disposed at both ends of the rotating shaft 21. The second scraper 27 abuts against the inner wall of the discharge hopper 1. While the rotating shaft 21 rotates, the second scraper 27 continuously scrapes the inner wall of the discharge hopper 1, so that concrete is prevented from being adhered to the inner wall of the discharge hopper 1.

Referring to fig. 2 and 3, the blade 28 is integrally formed on the ramming mass 22, and when the ramming mass 22 rotates, the blade 28 can cut the concrete, so that the concrete is not easy to agglomerate, and the concrete is more favorable for blanking.

Referring to fig. 1 and 2, a vibrator 4 is fixedly disposed on an outer wall of the discharge hopper 1. The vibrator 4 sets up in the both sides of going out hopper 1, can produce the tremble effect to going out hopper 1, effectively reduces the concrete and adheres to on the inner wall that goes out hopper 1.

The implementation principle of the embodiment of the application is as follows: during the blanking, the motor 32 is started, and the rotating shaft 21 drives the ramming rod 22 to rotate. The material smashing rod 22 and the blades 28 have the effect of cutting and stirring on concrete, so that the concrete is not easy to agglomerate, and the concrete is favorably fed. The second scraper 27 scrapes off the concrete on the inner wall of the discharge hopper 1.

After the unloading is accomplished, adnexed concrete is cleared up on first scraper blade 24 goes out hopper 1 inner wall, has effectively reduced the concrete and has condensed on hopper 1's inner wall, blocks up hopper 1.
