Description
Technical Field
[0001] This application relates to the field of concrete production equipment technology, and in particular to a protective device for a material conveyor belt in a concrete mixing plant. Background Technology
[0002] As the core equipment in modern construction engineering for concrete production, the stable operation of the material conveying system in a concrete mixing plant directly determines the efficiency and quality of concrete production. The material conveyor belt is responsible for transferring key raw materials such as aggregates, cement, and admixtures, precisely transporting these materials from storage silos to the mixer for mixing. It is a crucial link between raw material storage and concrete mixing. With the increasing demand for concrete production in construction projects, conveyor belts are often under high load and continuous operation. Their protective effect not only affects the stability of raw material conveying but is also closely related to production environment control and equipment lifespan. Therefore, the design of protective devices for conveyor belts has become one of the important directions for optimizing concrete mixing plant equipment.
[0003] However, the materials conveyed by the material conveyor belts used in current concrete mixing plants are prone to lateral splashing or bottom spillage due to vibration, centrifugal force, or uneven material thickness. The spilled material not only causes raw material loss but also requires additional manpower for cleaning, directly reducing production efficiency. At the same time, the spilled hard aggregates will fall into the drive structure inside the conveyor belt, thereby aggravating equipment wear, shortening the service life of the conveyor belt and idlers, and increasing equipment maintenance costs. Furthermore, the splashing of fine particles such as cement will form dust that spreads and pollutes the surrounding production environment, which not only fails to meet environmental protection requirements but may also affect the health of operators. Utility Model Content
[0004] The purpose of this application is to provide a protective device for the material conveyor belt of a concrete mixing plant. By setting an arc-shaped protective cover, the upper part of the material conveyor belt can be blocked, reducing the upward splashing of materials due to vibration and centrifugal force. Then, the protective telescopic plate and the side baffle cooperate to block both sides of the material conveyor belt, which can prevent materials from entering the equipment through gaps. This solves the problems mentioned in the background art.
[0005] The present application provides a protective device for a material conveyor belt in a concrete mixing plant, comprising a mounting frame. Two sets of symmetrical columns are fixedly connected to the upper side of the mounting frame. The material conveyor belt body is installed inside the mounting frame. Multiple equidistant horizontal braces are fixedly connected between the two sets of columns. An arc-shaped protective cover is provided on the upper side of the mounting frame. Connecting seats are provided on both sides of the arc-shaped protective cover. A fixed shaft is fixedly connected to the inner side of each of the two connecting seats, and the inner side of the arc-shaped protective cover is rotatably connected to the outer side of the fixed shaft. An adjusting component is provided on the surface of the outermost column among the two sets of columns. The two sets of adjusting components are symmetrically arranged. Each adjusting component includes a worm gear fixedly connected to the outer side of the fixed shaft, and a worm is meshed with the outer side of the worm gear. A synchronization component is provided on the outer side of the outermost horizontal brace. Protective telescopic plates are fixedly connected to the bottom surfaces of both connecting seats, and side baffles are hinged to the output ends of both protective telescopic plates.
[0006] By adopting the above technical solution, the arc-shaped protective cover can shield and protect the upper part of the material conveyor belt, reducing the upward splashing of materials due to vibration and centrifugal force. Then, the side baffles can block the sides of the material conveyor belt, reducing the possibility of lateral spillage of materials and preventing materials from entering the equipment through the gap between the material conveyor belt and the mounting frame, thereby improving the service life of the equipment. The adjustment component can adjust the position of the side baffles to adapt to the material conveying needs of different volumes. At the same time, the protective telescopic plate can extend and retract with the movement of the side baffles to ensure the continuity of side protection, thereby reducing raw material loss, reducing manual cleaning costs, improving production efficiency, and reducing material wear on the equipment and dust diffusion.
[0007] Preferably, the adjustment assembly further includes two fixing blocks fixedly connected to the outside of the column, and the two ends of the worm gear are rotatably connected to the inside of the fixing blocks.
[0008] By adopting the above technical solution, the fixing block provides stable support for the worm, ensuring the stability of the worm during rotation, making the meshing between the worm and the worm wheel more reliable, and ensuring the protective effect of the protective device.
[0009] Preferably, the synchronization component includes two first fixed seats fixedly connected to the outside of the cross brace, a rotating shaft rotatably connected to the inner side of the two first fixed seats, two symmetrical first bevel gears fixedly connected to the outer side of the rotating shaft, and a rotating wheel fixedly connected to one end of the rotating shaft.
[0010] By adopting the above technical solution, the first fixed seat provides stable support for the rotating shaft, and the rotating wheel can drive the rotating shaft and the first bevel gear to rotate synchronously, thereby realizing the transmission of power, ensuring that the synchronization component can coordinate the work of the two sets of adjustment components, so that the adjustment of both sides of the side baffle is consistent, and improving the adjustment convenience of the protective device.
[0011] Preferably, the synchronization component further includes two second fixing seats fixedly connected to the outside of the column, and the inner sides of the two second fixing seats are rotatably connected to connecting shafts. The bottom ends of the two connecting shafts are respectively fixedly connected to one end of the worm gear in the two sets of adjustment components.
[0012] By adopting the above technical solution, the second fixed seat provides stable support for the connecting shaft, which can transmit the power of the synchronization component to the worm gear, enabling the two sets of adjustment components to work together under the drive of the synchronization component, thus ensuring the structural stability and uniformity of the protective device.
[0013] Preferably, a second bevel gear is fixedly connected to the top end of each of the two connecting shafts, and the second bevel gear meshes with the first bevel gear.
[0014] By adopting the above technical solution, the meshing of the first bevel gear and the second bevel gear realizes the conversion of power in the horizontal and vertical directions, so that the rotation of the rotating shaft can drive the connecting shaft to rotate, thereby driving the adjustment component to work, ensuring the effective drive of the synchronization component to the adjustment component, and improving the synchronization and reliability of the adjustment of the protection device.
[0015] Preferably, the bottom surfaces of both side baffles are close to the surface of the material conveyor belt body, and multiple guide rods are fixedly connected to the side of the two side baffles that are far apart from each other, with the outer side of the guide rods inserted into the inner side of the mounting frame.
[0016] By adopting the above technical solution, the side baffle is close to the surface of the material conveyor belt body, which can enhance the blocking effect on the material and prevent the material from entering the equipment through the gap between the material conveyor belt body and the mounting frame, thereby improving the service life of the equipment. At the same time, the guide rod can guide the movement of the side baffle, ensure the stability of the side baffle during the movement, avoid the side baffle from deviating and affecting the protective effect, and further reduce material spillage and splashing.
[0017] Preferably, each group of columns contains multiple columns, with a first support rod fixedly connected between each pair of adjacent columns and a second support rod fixedly connected between each pair of adjacent cross braces.
[0018] By adopting the above technical solution, the first and second support rods can enhance the overall structural strength and stability of the column and cross brace, enabling the protective device to better withstand material impacts and external forces, extend the service life of the protective device, and ensure its long-term stable protective performance.
[0019] Preferably, the outer side of the arc-shaped protective cover is fixedly connected to the outer side of the second support rod by bolts, and the connecting seat is fixedly connected to the outer side of the first support rod by bolts.
[0020] By adopting the above technical solution, the bolt connection method makes the connection between the arc-shaped protective cover and the second support rod and the first support rod more stable and reliable, while facilitating disassembly and maintenance, reducing maintenance costs, and ensuring the continuous and effective operation of the protective device.
[0021] In summary, this application includes at least one of the following beneficial technical effects: This concrete mixing plant material conveyor belt protection device features an arc-shaped protective cover that shields the top of the conveyor belt, reducing material splashing upwards due to vibration and centrifugal force. The protective telescopic plate, in conjunction with the side baffles, blocks both sides of the conveyor belt. The side baffles, close to the surface of the conveyor belt, prevent material from entering the equipment through gaps. The worm gear and worm shaft in the adjustment assembly allow for adjustment of the side baffle position to accommodate materials of different volumes. Combined with the coordination of the first bevel gear, second fixed seat, and second bevel gear in the synchronization assembly, the two adjustment components work together to ensure consistent adjustment on both sides. This overall coordination effectively reduces raw material loss and manual cleaning costs, improves production efficiency, reduces equipment wear, and minimizes dust dispersion.

Detailed Implementation
[0024] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.
[0025] Example 1: A protective device for the material conveyor belt of a concrete mixing plant, please refer to... Figure 1 , Figure 2 and Figure 4 The system includes a mounting frame 1, with two sets of symmetrical columns 3 fixedly connected to the upper side of the mounting frame 1. The material conveyor belt body 2 is installed inside the mounting frame 1. Multiple equidistant horizontal support rods 4 are fixedly connected between the two sets of columns 3. An arc-shaped protective cover 5 is provided on the upper side of the mounting frame 1. This arc-shaped protective cover 5 can shield and protect the material conveyor belt body 2 from upward splashing due to vibration and centrifugal force. Connecting seats 6 are provided on both sides of the arc-shaped protective cover 5. A fixed shaft 7 is fixedly connected to the inner side of each connecting seat 6, and the inner side of the arc-shaped protective cover 5 is rotatably connected to the outer side of the fixed shaft 7. The outermost column 3 of the two sets of columns... The surface is equipped with adjustment components 8, and the two sets of adjustment components 8 are symmetrically arranged. The adjustment components 8 include a worm gear 801 fixedly connected to the outside of the fixed shaft 7. A worm 802 is meshed with the outside of the worm gear 801. A synchronization component 9 is provided on the outside of the outermost horizontal support rod 4. The bottom surfaces of the two connecting seats 6 are fixedly connected with protective telescopic plates 10. The output ends of the two protective telescopic plates 10 are hinged with side baffles 11. The side baffles 11 can block both sides of the material conveyor belt body 2, reduce the possibility of material spilling laterally, and prevent material from entering the equipment through the gap between the material conveyor belt body 2 and the mounting frame 1, thereby improving the service life of the equipment.
[0026] Please refer to Figure 1 and Figure 5The synchronization component 9 includes two first fixed seats 901 fixedly connected to the outside of the cross brace 4. A rotating shaft 902 is rotatably connected to the inner side of each of the two first fixed seats 901. Two symmetrical first bevel gears 904 are fixedly connected to the outer side of each rotating shaft 902. A rotating wheel 903 is fixedly connected to one end of each rotating shaft 902. The first fixed seats 901 provide stable support for the rotating shaft 902. Rotating the rotating wheel 903 drives the rotating shaft 902 and the first bevel gears 904 to rotate synchronously, thus transmitting power and ensuring that the synchronization component 9 can coordinate the operation of the two sets of adjustment components 8, keeping the adjustments on both sides of the side baffle 11 consistent and improving the ease of adjustment of the protective device. The synchronization component 9 also includes two second fixed seats 905 fixedly connected to the outside of the column 3. A connecting shaft 906 is rotatably connected to the inner side of each of the two second fixed seats 905. The bottom of each connecting shaft 906... The ends are respectively fixedly connected to one end of the worm gear 802 in the two sets of adjustment components 8. The second fixed seat 905 provides stable support for the connecting shaft 906. The connecting shaft 906 can transmit the power of the synchronization component 9 to the worm gear 802, so that the two sets of adjustment components 8 can work together under the drive of the synchronization component 9, ensuring the structural stability and uniformity of the protection device. The top ends of the two connecting shafts 906 are fixedly connected to the second bevel gear 907. The second bevel gear 907 meshes with the first bevel gear 904. The meshing of the first bevel gear 904 and the second bevel gear 907 realizes the conversion of power in the horizontal and vertical directions, so that the rotation of the rotating shaft 902 can drive the connecting shaft 906 to rotate, thereby driving the adjustment component 8 to work, ensuring the effective drive of the synchronization component 9 on the adjustment component 8, and improving the synchronicity and reliability of the adjustment of the protection device.
[0027] Example 2: A protective device for the material conveyor belt of a concrete mixing plant, please refer to... Figure 1 , Figure 3 and Figure 4The adjusting assembly 8 also includes two fixing blocks 803 fixedly connected to the outside of the column 3. The two ends of the worm gear 802 are rotatably connected to the inside of the fixing blocks 803. The fixing blocks 803 provide stable support for the worm gear 802, ensuring the stability of the worm gear 802 during rotation and making the meshing of the worm gear 802 and worm wheel 801 more reliable, thus ensuring the protective effect of the protective device. The bottom surfaces of the two side baffles 11 are close to the surface of the material conveyor belt body 2. Multiple guide rods 12 are fixedly connected to the side of the two side baffles 11 that are far apart from each other, and the outer side of the guide rods 12 is inserted into the inner side of the mounting frame 1. The side baffles 11 are close to the surface of the material conveyor belt body 2, which can enhance the blocking effect on the material and prevent the material from entering the equipment through the gap between the material conveyor belt body 2 and the mounting frame 1, thereby improving the service life of the equipment. At the same time, the guide rods 12 can guide the movement of the side baffles 11, ensuring that the side baffles 11 move smoothly. To ensure stability during operation and prevent the side baffles 11 from shifting and affecting the protective effect, further reducing material spillage and splashing, each set of columns 3 contains multiple columns. A first support rod 13 is fixedly connected between every two adjacent columns 3, and a second support rod 14 is fixedly connected between every two adjacent cross braces 4. The first support rod 13 and the second support rod 14 enhance the overall structural strength and stability of the columns 3 and cross braces 4, enabling the protective device to better withstand material impacts and external forces, extending the service life of the protective device, and ensuring its long-term stable protective performance. The outer side of the arc-shaped protective cover 5 is fixedly connected to the outer side of the second support rod 14 by bolts, and the connecting seat 6 is fixedly connected to the outer side of the first support rod 13 by bolts. The bolt connection method makes the connection between the arc-shaped protective cover 5, the second support rod 14, and the first support rod 13 more stable and reliable, while facilitating disassembly and maintenance, reducing maintenance costs, and ensuring the continuous and effective operation of the protective device.
[0028] The implementation principle of this application embodiment is as follows: When working, the material conveyor belt body 2 normally conveys aggregates, cement and other materials required for concrete production. Two sets of uprights 3 and multiple cross braces 4 cooperate to form a support frame to provide stable support for the subsequent protective structure. The first support rod 13 between adjacent uprights 3 and the second support rod 14 between adjacent cross braces 4 further enhance the structural strength of the support frame, ensuring that the device can withstand material impact and external forces. Then, during the material conveying process, the arc-shaped protective cover 5 shields the top of the material conveyor belt body 2, reducing the upward splashing of materials due to vibration and centrifugal force. At the same time, the protective telescopic plate 10 at the bottom of the connecting seat 6, together with the side baffle 11, blocks the sides of the material conveyor belt body 2. The bottom surface of the side baffle 11 is close to the surface of the material conveyor belt body 2, which can prevent materials from entering the equipment from the gap between the material conveyor belt body 2 and the mounting frame 1. The guide rod 12 on one side of the baffle 11 ensures its stability during movement and prevents deviation from affecting the protective effect. When the protective structure needs to be adjusted according to the material volume, the rotating wheel 903 is rotated, which drives the rotating shaft 902 and the first bevel gear 904 on the outside to rotate. The first bevel gear 904 meshes with the second bevel gear 907, transmitting power to the connecting shaft 906. The connecting shaft 906 then drives the worm gear 802 in the adjusting assembly 8 to rotate. The worm gear 802 meshes with the worm wheel 801 on the outside of the fixed shaft 7, driving the fixed shaft 7 and the connecting seat 6 to adjust the angle. At this time, the rotation of the connecting seat 6 can drive the protective telescopic plate 10 to rotate, thereby driving the side baffle 11 to move. This ensures the continuity of protection. During the adjustment process, the arc-shaped protective cover 5 is bolted to the second support rod 14, and the connecting seat 6 is bolted to the first support rod 13, which facilitates disassembly and maintenance when the device malfunctions, ensuring the continuous and stable operation of the entire device.
