[0002] Concrete is a common building material, which is made of cement, aggregates (such as sand, gravel), water and appropriate admixtures (such as fly ash, slag, etc.) mixed in a certain proportion. Concrete is widely used in construction to make foundations, floors, columns, beams and other structures. It has high strength and durability, can withstand a large amount of load and pressure, and provide stable support and structure for buildings.

[0003] During the construction process, concrete needs to be discharged. During the discharge process, the concrete raw materials will impact the inner wall of the discharge port. After a long period of impact, the discharge port may be damaged, which lacks the purpose of protecting the discharge port. However, if the protection function is simply added, during long-term use, when the protection components need to be disassembled, repaired and maintained, good disassembly efficiency cannot be achieved, which reduces the practicality of the device.

[0026] The utility model provides the following technical solutions:

[0027] Combination Figures 1 to 5 , a concrete discharge port anti-wear device, comprising a discharge barrel 1, a maintenance mechanism 2 is arranged on the outer side of the discharge barrel 1, and a discharge hopper 3 is movably connected to the inner wall of the discharge barrel 1;

[0028] The maintenance mechanism 2 includes a support arm 21, which is fixedly connected to the outer wall of the discharge barrel 1. A rectangular box 22 is fixedly connected to the side of the support arm 21 away from the discharge barrel 1. A threaded rod 23 is rotatably connected to the inner wall of the rectangular box 22. A movable plate 24 is threadedly connected to the outer wall of the threaded rod 23. A connecting arm 25 is fixedly connected to the front of the movable plate 24. A connecting block 26 is fixedly connected to the front of the connecting arm 25. An arc block 27 is fixedly connected to one side of the connecting block 26. A positioning block 28 is fixedly connected to one side of the arc block 27.

[0029] Furthermore, the movable plate 24 is slidably connected to the inner wall of the rectangular box 22, and a handle is fixedly connected to the right end of the threaded rod 23, so that the threaded rod 23 can be rotated by shaking the handle.

[0030] Furthermore, a moving opening is opened on the front side of the rectangular box 22, and the connecting arm 25 passes through the moving opening, so that the connecting arm 25 can move stably through the moving opening.

[0031] Furthermore, the threads of the outer walls at both ends of the threaded rod 23 are in opposite directions. The threaded rod 23 passes through the right side of the rectangular box 22 and rotates, so that the rotational motion of the threaded rod 23 is converted into the linear motion of the moving plate 24.

[0032] Furthermore, a moving opening is opened on the outer side of the discharge barrel 1, and the positioning block 28 passes through the moving opening and moves, so that the positioning block 28 can move through the moving opening.

[0033] Furthermore, a rectangular opening is formed on the outer wall of the lower hopper 3 , and the positioning block 28 is inserted into the inner wall of the rectangular opening, so that the positioning block 28 can limit the lower hopper 3 through the action of the rectangular opening.

[0034] Furthermore, the lower hopper 3 includes a reinforcement layer 31, the outer wall of the reinforcement layer 31 is fixedly connected to a pressure-resistant layer 32, the outer wall of the pressure-resistant layer 32 is fixedly connected to a corrosion-resistant layer 33, and the outer wall of the corrosion-resistant layer 33 is fixedly connected to a wear-resistant layer 34, further extending the service life of the lower hopper 3.

[0036] In actual operation, when this device is used, the lower barrel 1 can be installed in the loading position during use. During the loading process, the lower hopper 3 can reduce the damage caused by concrete raw materials to the inner wall of the lower barrel 1. At the same time, the handle is twisted to drive the threaded rod 23 to rotate, so that the movable plate 24 can drive the positioning block 28 to separate from the inner wall of the rectangular opening opened on the outer wall of the lower hopper 3 through the connecting arm 25 and the arc block 27, thereby canceling the limit on the lower hopper 3. Then, the lower hopper 3 can be driven to rise by lifting the connecting frame upwards, so that the lower hopper 3 can be disassembled, which is convenient for disassembly, inspection and maintenance of the lower hopper 3 during long-term use to achieve good operating efficiency and enhance the practicality of the device.

[0037] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
