Description

Technical Field

[0001] This utility model relates to the field of feed hopper technology for concrete mixing plants, and more particularly to feed hopper for concrete mixing plants used in building construction. Background Technology

[0002] In the current booming construction industry, the feed hopper of a concrete mixing plant plays a crucial role in receiving materials. As the scale of various construction projects continues to increase and the pace of construction accelerates, the performance requirements for the feed hopper are becoming increasingly stringent. It needs to efficiently receive large quantities of raw materials such as sand, gravel, and cement unloaded from transport vehicles, adapt to different unloading speeds and material forms, and ensure that materials flow continuously and stably into the mixing system. This lays a solid foundation for subsequent accurate proportioning and uniform mixing. Traditionally, before feeding materials, manual turning and screening of the materials are required, and then the materials are fed into the mixing plant through the feed hopper.

[0003] However, with current technology, manual turning and screening of materials makes it difficult to guarantee the screening effect and uniformity, prolonging the mixing cycle and reducing the production efficiency of the mixing plant. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a concrete mixing plant feed hopper for building construction, which aims to solve the problems of difficulty in ensuring the screening effect and uniformity, prolonging the mixing cycle, and reducing the production efficiency of the mixing plant.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A concrete mixing plant feed hopper for construction includes a feed hopper body. A U-shaped frame is fixedly connected to the outer wall of the feed hopper body. A motor is fixedly connected to the outer wall of the U-shaped frame. A crank is fixedly installed at the output end of the motor. A transmission column is rotatably connected to the outer wall of the crank. A rotating frame is rotatably connected to the outer wall of the feed hopper body. The outer wall of the transmission column is slidably connected to the inner wall of the rotating frame. A connecting column is fixedly connected to the upper interior of the rotating frame. A sliding block is rotatably connected to the outer wall of the connecting column. A guide frame is slidably connected to the inner wall of the feed hopper body. The outer wall of the sliding block is slidably connected to the inner wall of the guide frame. A reciprocating frame is fixedly connected to the outer wall of the guide frame. A guide rail is slidably connected inside the reciprocating frame. Both ends of the guide rail are fixedly connected to the inner wall of the feed hopper body. The reciprocating frame is a hollow structure. A screen frame is provided on the inner wall of the reciprocating frame. An installation assembly is provided on the lower surface of the feed hopper body. The installation assembly is used to install the feed hopper onto the mixing plant.

[0007] Preferably, the mounting assembly includes a fixing column, the top end of which is fixedly connected to the lower surface of the feed hopper body, and the bottom end of which is fixedly connected to a mounting lug.

[0008] Preferably, a first pull plate is slidably connected to the inner wall of one side of the reciprocating frame, and a second pull plate is slidably connected to the inner wall of the other side of the reciprocating frame. A first sealing plate is fixedly connected to the outer wall of the first pull plate, and the outer wall of the first sealing plate is slidably connected to the inner wall of the second pull plate. A second sealing plate is fixedly connected to the outer wall of the second pull plate, and the outer wall of the first sealing plate is slidably connected to the inner wall of the second sealing plate.

[0009] Preferably, a movable column is fixedly connected to one side of the outer wall of the first pull plate, and a movable column is fixedly connected to one side of the outer wall of the second pull plate. An inclined block is fixedly connected to the outer wall of the movable column, and the outer wall of the inclined block is slidably connected to the inner wall of the reciprocating frame.

[0010] Preferably, a first spring is fixedly connected to the other side of the first pull plate, and the other side of the second pull plate is fixedly connected to the outer wall of the first spring. The outer wall of the first spring is fixedly connected to the inner wall of the reciprocating frame.

[0011] Preferably, a positioning plate is fixedly connected to the outer wall of the screen frame, the outer wall of the positioning plate is disposed on the inner wall of the reciprocating frame, and the outer wall of the inclined block is disposed on the upper and lower surfaces of the positioning plate.

[0012] Preferably, the reciprocating frame is internally slidably connected to a top column, and the upper surface of the top column is disposed on the lower surface of the positioning plate.

[0013] Preferably, a second spring is fixedly connected to the lower surface of the top column, and the bottom end of the second spring is fixedly connected to the inner wall of the reciprocating frame.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, when the motor is turned on, its output end drives the crank to rotate. The crank causes the transmission column to slide up and down on the inner wall of the rotating frame, causing the rotating frame to swing back and forth. The rotating frame drives the sliding block to slide up and down in the guide frame via the connecting column, thereby driving the reciprocating frame to move on the guide rail. Through the sieve frame turning and sieving the concrete material, the uniformity and filtration efficiency are improved.

[0016] 2. In this utility model, pulling the first and second pull plates to move them inwards causes the moving column to move inwards, disengaging the inclined block from the upper surface of the positioning plate. The second spring rebounds and lifts the top column, pushing the positioning plate upwards, allowing for quick disassembly of the screen frame. During installation, the screen frame positioning plate is aligned with the groove and pressed down. After the inclined block moves down, the first spring rebounds and pushes the pull plate outwards. The moving column causes the inclined block to abut against the positioning plate, working with the top column to fix the screen frame. This achieves convenient installation and disassembly of the screen frame, ensuring its filtration performance and improving the quality stability of the concrete. Attached Figure Description

[0022] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0023] Reference Figure 1 and Figure 2 This utility model provides an embodiment of a concrete mixing plant feed hopper for construction, comprising a feed hopper body 1, a U-shaped frame 2 fixedly connected to the outer wall of the feed hopper body 1, a motor 3 fixedly connected to the outer wall of the U-shaped frame 2, a crank 4 fixedly installed at the output end of the motor 3, a transmission column 5 rotatably connected to the outer wall of the crank 4, a rotating frame 6 rotatably connected to the outer wall of the feed hopper body 1, the outer wall of the transmission column 5 slidably connected to the inner wall of the rotating frame 6, and a connecting column 7 fixedly connected to the upper inner side of the rotating frame 6. A sliding block 8 is rotatably connected, and a guide frame 9 is slidably connected to the inner wall of the feed hopper body 1. The outer wall of the sliding block 8 is slidably connected to the inner wall of the guide frame 9. A reciprocating frame 10 is fixedly connected to the outer wall of the guide frame 9. A guide rail 24 is slidably connected inside the reciprocating frame 10. Both ends of the guide rail 24 are fixedly connected to the inner wall of the feed hopper body 1. The reciprocating frame 10 has a hollow structure. A screen frame 11 is provided on the inner wall of the reciprocating frame 10. An installation component is provided on the lower surface of the feed hopper body 1. The installation component is used to install the feed hopper onto the mixing station.

[0024] Specifically, the feed hopper body 1 provides fixed support for the U-shaped frame 2, and the U-shaped frame 2 supports the position of the motor 3. When the motor 3 is turned on, its output end can drive the crank 4 to rotate. The crank 4 can drive the transmission column 5 to slide up and down on the inner wall of the rotating frame 6. The feed hopper body 1 can support the rotation position of the rotating frame 6, thereby driving the rotating frame 6 to swing back and forth on the outer wall of the feed hopper body 1. When the rotating frame 6 swings, it can synchronously drive the connecting column 7 to swing. The connecting column 7 can drive the sliding block 8 to move in the guide frame. The inner wall of 9 moves up and down, and the guide frame 9 can be driven to reciprocate on the inner wall of the feed hopper body 1 by the sliding block 8. The reciprocating frame 10 has a fixed support function for the guide frame 9, so that the reciprocating frame 10 can be driven to reciprocate on the outer wall of the guide rail 24. The reciprocating frame 10 can support the installation position of the screen frame 11. The screen frame 11 is equipped with a screen to filter large particles of impurities in the material, so as to continuously turn and screen the material on the screen frame 11, improve the uniformity of the material when it enters the mixing station and the material filtration efficiency.

[0025] Reference Figure 1 The mounting assembly includes a fixing column 12, the top end of which is fixedly connected to the lower surface of the feed hopper body 1, and the bottom end of which is fixedly connected to a mounting ear 13.

[0026] Specifically, the fixed column 12 supports the feed hopper body 1, and the feed hopper can be installed as a whole at the feeding position of the mixing plant through the mounting ear 13.

[0027] Reference Figure 1 and Figure 3 A first pull plate 15 is slidably connected to the inner wall of one side of the reciprocating frame 10, and a second pull plate 22 is slidably connected to the inner wall of the other side of the reciprocating frame 10. A first sealing plate 21 is fixedly connected to the outer wall of the first pull plate 15, and the outer wall of the first sealing plate 21 is slidably connected to the inner wall of the second pull plate 22. A second sealing plate 23 is fixedly connected to the outer wall of the second pull plate 22, and the outer wall of the first sealing plate 21 is slidably connected to the inner wall of the second sealing plate 23.

[0028] Specifically, the reciprocating frame 10 can support the sliding position of the first pull plate 15 and the second pull plate 22. The first pull plate 15 has a fixed support function for the first sealing plate 21, while the second pull plate 22 has a fixed function for the second sealing plate 23. The first sealing plate 21 and the second sealing plate 23 can ensure that when the screen frame 11 is limited, the sliding gap between the first pull plate 15 and the second pull plate 22 will not enter the material, thus making it difficult to slide.

[0029] Reference Figures 1-3A movable column 16 is fixedly connected to one side of the outer wall of the first pull plate 15. A movable column 16 is fixedly connected to one side of the outer wall of the second pull plate 22. An inclined block 17 is fixedly connected to the outer wall of the movable column 16. The outer wall of the inclined block 17 is slidably connected to the inner wall of the reciprocating frame 10. A first spring 18 is fixedly connected to the other side of the first pull plate 15. The other side of the second pull plate 22 is fixedly connected to the outer wall of the first spring 18. The outer wall of the first spring 18 is fixedly connected to the inner wall of the reciprocating frame 10. A positioning plate 14 is fixedly connected to the outer wall of the screen frame 11. The outer wall of the positioning plate 14 is set on the inner wall of the reciprocating frame 10. The outer wall of the inclined block 17 is set on the upper and lower surfaces of the positioning plate 14. A top column 19 is slidably connected inside the reciprocating frame 10. The upper surface of the top column 19 is set on the lower surface of the positioning plate 14. A second spring 20 is fixedly connected to the lower surface of the top column 19. The bottom end of the second spring 20 is fixedly connected to the inner wall of the reciprocating frame 10.

[0030] Specifically, the first pull plate 15 and the second pull plate 22 respectively provide fixed support for the moving column 16, and when they move, they can drive the inclined block 17 to slide on the inner wall of the reciprocating frame 10 through the moving column 16. The first spring 18 can drive the first pull plate 15 and the second pull plate 22 to move outward through the reverse force between it and the reciprocating frame 10. The screen frame 11 provides fixed support for the positioning plate 14, while the reciprocating frame 10 can support the installation position of the positioning plate 14. The inclined block 17 can limit the installation position of the positioning plate 14. The reciprocating frame 10 can support the sliding position of the top column 19, and the top column 19 can push the positioning plate 14 upward through the reverse force generated by the second spring 20 and the reciprocating frame 10, thereby limiting the installation position of the positioning plate 14 through the cooperation of the inclined block 17.

[0031] Working principle: When the feed hopper is needed, first install the entire feed hopper to the feeding position of the mixing plant using the mounting ears 13. Then, pour the concrete material into the reciprocating frame 10, and then turn on the motor 3. The output end of the motor 3 can drive the crank 4 to rotate. When the crank 4 rotates, it can drive the transmission column 5 to slide up and down on the inner wall of the rotating frame 6, thereby driving the rotating frame 6 to swing back and forth on the outer wall of the feed hopper body 1. The rotating frame 6 can drive the sliding block 8 to slide up and down on the inner wall of the guide frame 9 through the connecting column 7, thereby driving the guide frame 9 to reciprocate on the inner wall of the feed hopper body 1. The reciprocating frame 10 moves back and forth on the outer wall of the guide rail 24, continuously turning and screening the concrete material on the screen frame 11. This prevents excessive accumulation of material on the screen frame 11, improving material uniformity and filtration efficiency. When the screen frame 11 needs to be replaced, the first pull plate 15 and the second pull plate 22 are pulled in opposite directions. The first pull plate 15 and the second pull plate 22 simultaneously drive the moving column 16 inward, which then disengages from the inclined block 17 and the upper surface of the positioning plate 14. At this time, the second spring 20 rebounds, pushing the top column 19. Moving upwards pushes the positioning plate 14 upwards, quickly disassembling the screen frame 11 from the inner wall of the reciprocating frame 10. During installation, the positioning plates 14 at all four ends of the screen frame 11 are aligned with the grooves in the reciprocating frame 10 and moved downwards. After the positioning plates 14 move downwards via the inclined blocks 17, the first spring 18 rebounds, pushing the first pull plate 15 and the second pull plate 22 outwards simultaneously. This causes the lower surface of the inclined block 17 to contact the upper surface of the positioning plate 14 via the moving column 16. The upward force of the top column 19, combined with the cooperation of the inclined blocks 17, ensures that the screen frame 11 re-enters the inner wall of the reciprocating frame 10. The hopper provides stability, allowing for the installation and fixation of the screen frame 11. Simultaneously, the outward movement of the first pull plate 15 and the second pull plate 22 causes the first sealing plate 21 and the second sealing plate 23 to come into contact, preventing concrete material from entering the gap between the first pull plate 15 and the second pull plate 22 during the operation of the hopper body 1. This means the hopper not only enables the screen frame 11 to reciprocate, improving material uniformity and filtration efficiency, but also allows for the installation, disassembly, and replacement of the screen frame 11, ensuring its filtration performance for different materials and thus improving the quality stability of the concrete.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
