[0002] Concrete mixing plants are essential equipment in the construction industry, primarily used for centralized concrete production. They play a crucial role in various construction projects, such as building construction, road and bridge construction, water conservancy projects, and municipal engineering. During operation, concrete mixing plants require feeding materials into their interiors through the inlet.

[0003] Utility model patent CN214353329U discloses a protective device for the feed inlet of a concrete mixing plant, including a working box containing a mixing tank. A first bracket is connected to the upper right side of the mixing tank, and a second bracket is connected to the upper left side of the mixing tank. A fixing plate is horizontally arranged between the first and second brackets. A feed inlet is opened at the top of the mixing tank, and the fixing plate is located above the feed inlet. A locking assembly is provided on the right side of the second bracket. The locking assembly includes a fixing block with an installation groove inside. A connecting rod is connected inside the installation groove, passing through the interior of the installation groove and extending above it. A spring is connected to the upper side of the connecting rod. Under the combined action of the locking assembly and the fixing plate, the amount of feed is controlled, and under the action of the buffer plate, the speed at which the feed enters the mixing tank is slowed down, protecting the equipment inside the mixing tank.

[0004] In the aforementioned prior art, during the use of the feed inlet, due to the stickiness of the material added inside, some material adheres to the inner wall of the feed inlet after feeding, resulting in material waste. Therefore, improvements are needed. Utility Model Content

One end of the first spring 84 is fixedly connected to the slider 82, and the other end of the first spring 84 is fixedly connected to the fixed seat 6. By designing the first spring 84, the force of the first spring 84 can act on the slider 82. A pressure plate 85 is fixedly connected to the bottom of the pressure rod 4.

By designing the cleaning mechanism 8, it is convenient to clean the inside of the feed inlet 1.

[0024] Please see Figure 1 , Figure 2 , Figure 4 The connecting mechanism 9 includes an insert block 91, which is slidably fitted inside the pressure plate 85. A push rod 92 is fixedly connected to the top of the insert block 91, and the push rod 92 is slidably connected to the pressure plate 85.

[0025] The specific implementation process of this utility model is as follows: In use, the material is first input through the feed inlet 1. After the feeding is completed, the output end of the hydraulic cylinder 3 drives the pressure rod 4 to move down. The pressure rod 4 will drive the fixed seat 6 and the pressure cover 5 to move down. The pressure cover 5 will first be fitted inside the feed inlet 1, and the pressure cover 5 can close the feed inlet 1. Then the output end of the hydraulic cylinder 3 drives the pressure rod 4 to continue to move down. The pressure rod 4 will drive the slider 82 to slide along the fixed rod 83 and squeeze the first spring 84. Under the elastic action of the first spring 84, a downward pushing force will be given to the fixed seat 6, so that the pressure cover 5 can be tightly attached to the feed inlet 1. When the pressure rod 4 moves down, it will drive the pressure plate 85 and the scraper ring 86 to move down. The pressure plate 85 can prevent the material from splashing out when mixing. At the same time, it can realize the sliding of the scraper ring 86 inside the feed inlet 1. The scraper ring 86 can scrape off the residual material on the inner wall of the feed inlet 1 and push it down, which can avoid the problem of material residue causing waste.

[0026] When the scraper ring 86 needs to be disassembled, first move the pressure plate 85 out of the feed port 1, then push the push rod 92 horizontally. The push rod 92 drives the insert block 91 to move horizontally, and the insert block 91 drives the magnetic suction rod 94 to move horizontally. The insert block 91 will squeeze the second spring 95. When the magnetic suction rod 94 is attracted to the magnet 96, the insert block 91 will slide out from the inside of the scraper ring 86. Then the scraper ring 86 can be removed from the pressure plate 85, which makes it easy to disassemble the scraper ring 86. After use, it is easy to disassemble and clean the scraper ring 86 for subsequent reuse.
