Description

Technical Field

[0001] This utility model relates to the field of safety protection technology for concrete mixing plants, and in particular to a protective device for the feed inlet of a concrete mixing plant. Background Technology

[0002] A concrete mixing plant is a specialized equipment for the centralized production of concrete. It produces concrete that meets the engineering requirements by mixing raw materials such as cement, sand, gravel, water, and admixtures in a certain proportion. It is widely used in building construction, road and bridge construction, water conservancy projects and other fields, and is an indispensable key equipment in modern engineering construction. During the production process, concrete mixing plants typically install protective devices at the feed inlet. These devices are designed to ensure the safe operation of the mixing plant during the feeding process and to prevent personnel or debris from entering the feed inlet and causing safety accidents or affecting material quality. They play a crucial role in the safe production of the mixing plant and can effectively reduce the risks of mechanical injury and equipment damage. However, existing feed inlet protective devices have certain inconveniences in use. Currently, most concrete mixing plant feed inlet protection devices are manually operated. This operating mode has obvious drawbacks in practical applications: on the one hand, it requires workers to frequently operate the device manually to open and close, which increases the labor intensity of the workers, especially in production scenarios with high-frequency feeding, and can easily lead to operator fatigue; on the other hand, during the manual opening and closing process, due to factors such as the precision and force control of human operation, the protection device and the feed inlet are prone to not fitting tightly, resulting in poor sealing. This may not only allow foreign matter to mix into the material, but may also cause safety hazards such as material splashing, which has an adverse impact on production efficiency and operational safety. Therefore, we propose a protective device for the feed inlet of a concrete mixing plant. Utility Model Content

[0003] In existing technologies, frequent manual operation of the device opening and closing by workers increases the labor intensity of operators, especially in high-frequency feeding production scenarios, which can easily lead to operator fatigue. During manual opening and closing, factors such as the precision and force control of human operation can affect the tightness of the protective device and the feed inlet, resulting in poor sealing. This can not only allow impurities to mix into the material, but also cause safety hazards such as material splashing, which adversely affect production efficiency and operational safety. To address these technical problems, this utility model provides a protective device for the feed inlet of a concrete mixing plant.

[0004] The technical solution adopted by this utility model is: a protective device for the feed inlet of a concrete mixing plant, including a feed pipe and an adjustment component. The adjustment component includes a fixed frame, a front frame, a rotating disk, a servo motor, a fixed plate, an electric push rod, and a connecting plate. The front frame is disposed on the outer surface of the front end of the fixed frame. The rotating disk is movably connected to the middle of the front frame. The servo motor is fixedly installed on the outer surface of the rear end of the fixed frame. The fixed plate is disposed on the outer surface of the front end of the rotating disk. The electric push rod is fixedly installed on the outer surface of the lower end of the fixed plate. The connecting plate is fixedly installed on the outer surface of one end of the electric push rod.

[0005] Furthermore, a fixed carrier plate is fixedly installed on the outer wall of the feed pipe, a protective cover is provided above the fixed carrier plate, and a docking retainer is provided on the upper outer surface of the fixed carrier plate.

[0006] Furthermore, an integrated air pump is fixedly installed on the upper outer surface of the protective cover, and an air guide pipe is provided on the outer wall of the integrated air pump. A slot is provided on the lower outer surface of the protective cover, and an airbag is provided in the middle of the slot.

[0007] Furthermore, the fixing frame is welded to the front frame, and the output end of the servo motor is connected to the outer surface of the rear end of the rotating disk.

[0008] Furthermore, the fixed plate is welded to the rotating disk, and the electric push rod passes through the fixed plate.

[0009] Furthermore, the protective cover and the slot are integrally formed, the airbag is an annular structure, and the air duct and the airbag are connected.

[0010] The beneficial effects of this utility model are: In this invention, the protective cover can be automatically opened and closed by adjusting the components, which can avoid manual operation by workers, reduce the labor force of workers, improve work efficiency, and can be accurately reset during use to avoid the situation of incomplete closure.

[0011] In this invention, when the protective cover is closed, the slot at the lower end of the protective cover aligns with the docking ring on the fixed carrier plate. Then, the integrated air pump inflates the airbag through the air pipe, causing the airbag to expand between the slot and the docking ring. This improves the sealing performance between the protective cover and the fixed carrier plate, preventing material spillage. Attached Figure Description

[0016] The following is in conjunction with the appendix Figures 1-4 The present invention will be further described below.

[0017] In order to solve the problems existing in the background technology, this application proposes the following technical solution: a protective device for the feed inlet of a concrete mixing plant.

[0018] The specific technical solution includes a feed inlet 1 and an adjustment assembly 4. The adjustment assembly 4 includes a fixed frame 401, a front frame 402, a rotating disk 403, a servo motor 404, a fixed plate 405, an electric push rod 406, and a connecting plate 407. The front frame 402 is located on the outer surface of the front end of the fixed frame 401. The rotating disk 403 is movably connected to the middle of the front frame 402. The servo motor 404 is fixedly installed on the outer surface of the rear end of the fixed frame 401. The fixed plate 405 is located on the outer surface of the front end of the rotating disk 403. The electric push rod 406 is fixedly installed on the outer surface of the lower end of the fixed plate 405. The connecting plate 407 is fixedly installed on the outer surface of one end of the electric push rod 406. When in use, the adjustment assembly 4 can be fixedly connected to the protective cover 3 through the connecting plate 407. Then, the protective cover 3 can be raised and lowered by the electric push rod 406. When it is necessary to open the protective cover... At time 3, the electric push rod 406 drives the protective cover 3 to rise. When it rises to a certain height, the servo motor 404 starts and drives the rotating disk 403 to rotate, causing the rotating disk 403 to drive the fixed plate 405 to rotate. This allows the electric push rod 406 on the fixed plate 405 to be leveled, causing the protective cover 3 to flip. When the protective cover 3 needs to be closed, the servo motor 404 can be reversed, causing the rotating disk 403 to drive the fixed plate 405 to reset. Then, the fixed plate 405 drives the electric push rod 406 back to the center. At this time, the protective cover 3 is reset above the feed pipe 1, and the electric push rod 406 drives the protective cover 3 to move downward to close. The protective cover 3 can be automatically opened and closed by adjusting the component 4, which can avoid manual operation by workers, reduce the labor force of workers, improve work efficiency, and allow for precise reset during use, avoiding the situation of incomplete closure.

[0019] Furthermore, the fixed frame 401 is welded to the front frame 402, the output end of the servo motor 404 is connected to the outer surface of the rear end of the rotating disk 403, the fixed plate 405 is welded to the rotating disk 403, the electric push rod 406 passes through the fixed plate 405, the servo motor 404 can drive the rotating disk 403 to rotate, and the rotating disk 403 can drive the electric push rod 406 to rotate through the fixed plate 405, so that the electric push rod 406 can be laid flat and erected.

[0020] Reference Figure 1 , Figure 3 and Figure 4As shown, a fixed carrier plate 2 is fixedly installed on the outer wall of the feed inlet 1. A protective cover 3 is provided above the fixed carrier plate 2. A docking ring 5 is provided on the upper outer surface of the fixed carrier plate 2. An integrated air pump 6 is fixedly installed on the upper outer surface of the protective cover 3. An air guide pipe 7 is provided on the outer wall of the integrated air pump 6. A slot 8 is provided on the lower outer surface of the protective cover 3. An air bladder 9 is provided in the middle of the slot 8. When the protective cover 3 is closed, the slot 8 at the lower end of the protective cover 3 docks with the docking ring 5 on the fixed carrier plate 2. Then, the integrated air pump 6 can inflate the air bladder 9 through the air guide pipe 7, which can cause the air bladder 9 to expand between the slot 8 and the docking ring 5, thereby improving the sealing performance between the protective cover 3 and the fixed carrier plate 2 and preventing material spillage.

[0021] Furthermore, the protective cover 3 and the slot 8 are integrally formed, the airbag 9 is an annular structure, and the air duct 7 and the airbag 9 are a through structure. When in use, the airbag 9 is mainly used to improve the seal between the slot 8 and the docking ring 5, thereby improving the closure and sealing between the protective cover 3 and the fixed carrier plate 2.

[0022] To ensure that those skilled in the art can fully understand the technical solution, this application provides the following overall overview: In use, the fixed carrier plate 2 is fixed to the outer wall of the inlet 1, and then the fixing bracket 401 is installed on the fixed carrier plate 2. The connecting plate 407 is installed on the protective cover 3. The protective cover 3 can be raised and lowered by the electric push rod 406. When the protective cover 3 needs to be opened, the electric push rod 406 drives the protective cover 3 to rise. When it rises to a certain height, the servo motor 404 starts and drives the rotating disk 403 to rotate, so that the rotating disk 403 drives the fixed plate 405 to rotate, thereby allowing the electric push rod 406 on the fixed plate 405 to be laid flat and the protective cover 3 to be flipped. When the protective cover 3 needs to be closed, the servo motor 404 can be started to drive the rotating disk 403 to rotate, thereby allowing the electric push rod 406 on the fixed plate 405 to be laid flat and the protective cover 3 to be flipped. When the protective cover 3 needs to be closed, the servo motor 406 can be started to rotate. 04 Reverse rotation causes the rotating disk 403 to drive the fixed plate 405 to reset. Then, the fixed plate 405 drives the electric push rod 406 back to the center. At this time, the protective cover 3 resets to above the feed inlet 1. The electric push rod 406 drives the protective cover 3 to move downward to close. When the protective cover 3 closes, the slot 8 at the lower end of the protective cover 3 aligns with the docking ring 5 placed on the fixed carrier plate 2. Then, the integrated air pump 6 can inflate the airbag 9 through the air guide pipe 7, which can cause the airbag 9 to expand between the slot 8 and the docking ring 5, thereby improving the sealing performance between the protective cover 3 and the fixed carrier plate 2 and preventing material spillage.
