Abstract
Description
Technical Field

[0002] Concrete production uses cement, sand, gravel and water as raw materials, and undergoes processes such as mixing, pouring and hardening to produce concrete products of various specifications and models. At present, in the concrete production process, a hopper is needed to discharge the concrete. However, during the use of the hopper, the outlet at the bottom of the hopper is prone to blockage.
[0003] After searching, the patent with publication number: CN217802502U proposes a concrete feeding device for concrete production, which can realize the portion-by-portion feeding of concrete by closing the bottom of the discharge pipe through the closing component, so as to realize the reasonable use of concrete according to specific needs, which can save costs to a certain extent. The outer ring inside the device can not only ensure that the concrete inside the discharge pipe will not be difficult to discharge due to extrusion, but also can better clean the residual concrete on the inner wall when it is not needed to be cleaned because the outer surface of the outer ring fits the inner wall of the discharge pipe, which can greatly ensure the service life of the machine. However, the device has the following problems when in use: the second threaded column and the threaded member are located in the discharge pipe. When the second threaded column is driven to rotate by external force, the driving device installed in the discharge pipe affects the concrete feeding process, and the manual rotation needs to be inserted into the discharge pipe, but the bottom fixing member and the slide rail of the discharge pipe form a shield, and the operation is difficult, resulting in the residual material in the discharge pipe not being easy to clean and easy to form a blockage.

[0022] A push rod 5 is fixedly connected to the bottom of the output end of the electric push rod 4, and a cross rod 6 is fixedly connected to the bottom of the push rod 5. An annular scraper 7 is fixedly sleeved on the outer wall of the cross rod 6. The operation of the electric push rod 4 drives the push rod 5 and the cross rod 6 to move downward. The outer wall of the annular scraper 7 is slidingly connected to the inner wall of the discharge pipe 2. The downward movement of the cross rod 6 drives the annular scraper 7 to move downward, thereby cleaning the outer wall of the discharge pipe 2. A guide plate 8 is fixedly connected to the outer wall of the discharge pipe 2, and the guide plate 8 assists the concrete to flow out.
[0023] The outer wall of the discharge pipe 2 is provided with a discharge mechanism, which includes two arc-shaped plates 12. Four fixed blocks 9 are fixedly connected to the outer wall of the discharge pipe 2. The four fixed blocks 9 are rotatably connected to a pin in a group of two. The outer walls of the two pins are rotatably sleeved with a semicircular plate 10. An arc design is made between the two semicircular plates 10. The semicircular plates 10 rotate with the pin as a fulcrum. The outer walls of the two semicircular plates 10 are fixedly connected with a rectangular rod 11. The outer wall of the rectangular rod 11 is squeezed with the outer wall of the arc plate 12, and the rectangular rod 11 drives the semicircular plates 10 to rotate.
[0024] The outer wall of the rectangular rod 11 is fixedly inlaid with a threaded rod 14, and the rotation of the rectangular rod 11 drives the threaded rod 14 to rotate. The outer wall of the arc plate 12 is provided with an arc groove 13, and the inner wall of the arc groove 13 is slidably connected to the outer wall of the threaded rod 14. The arc groove 13 assists the threaded rod 14 to rotate. The outer wall of the threaded rod 14 is threadedly connected to two locking nuts 15.

If a blockage is encountered during discharge, the electric push rod 4 drives the push rod 5 and the cross rod 6 to move downward, and the cross rod 6 moves downward to drive the annular scraper 7 to move downward. The annular scraper 7 and the cross rod 6 push the concrete in the discharge pipe 2 to move downward, and the extrusion force causes it to move downward to avoid blockage. At the same time, during subsequent cleaning, the annular scraper 7 moves downward to clean the residual material in the discharge pipe 2 to avoid affecting subsequent use.
