Description

Technical Field

[0001] This utility model relates to the technical field of concrete processing equipment, specifically to a material retaining structure for an asphalt concrete mixing plant. Background Technology

[0002] In the preparation of asphalt concrete, the mixing plant plays a crucial role. The conveyor belt system is a key piece of equipment for transporting various raw materials (such as aggregates and asphalt) from one processing point to another. However, in actual operation, when aggregates are fed onto the conveyor belt, uneven distribution may occur, leading to excessive aggregate accumulation in some areas. This not only affects subsequent processes but may also result in material waste or a decline in product quality.

[0003] Furthermore, traditional conveyor belt systems lack effective material control measures, making it impossible to precisely control aggregate flow when it is necessary to stop material transport or adjust material flow. This can cause aggregate to overflow from the conveyor belt edges, resulting in on-site chaos and safety hazards. To address these issues and improve production efficiency and product quality, improvements to conveyor belt systems are essential.

[0004] To address the aforementioned problems, some solutions have been proposed in the prior art, but these solutions typically suffer from drawbacks such as complex structures, inconvenient maintenance, or high costs. For example, some devices use robotic arms or other complex mechanical structures to level aggregates, but such designs increase system complexity, raise the failure rate, and place higher demands on daily maintenance. Meanwhile, traditional material-blocking methods often rely on fixed baffles, lacking flexibility and unable to adjust the baffle height in real time according to actual conditions, making it difficult to meet diverse production needs.

[0005] Therefore, there is an urgent need for a new type of material retaining structure that can effectively smooth out raised aggregates and flexibly control aggregate flow, so as to simplify the structure of the conveyor belt system, reduce maintenance costs, and improve the working efficiency and safety of asphalt concrete mixing plants. Utility Model Content

[0006] In view of the shortcomings in the prior art, this utility model provides a material retaining structure for an asphalt concrete mixing plant.

[0007] The technical solution adopted by this utility model is: a material blocking structure for an asphalt concrete mixing plant, including a conveyor belt support and a conveyor belt set on the conveyor belt support, as well as a paving mechanism for smoothing out raised aggregates and a material blocking mechanism for blocking aggregates.

[0008] The material blocking mechanism includes a material blocking bracket fixed on the conveyor belt support, a cylinder bracket fixed on the material blocking bracket, a power component fixed on the cylinder bracket, a mounting plate connected to the output end of the power component, a guide rod slidably connected to the mounting plate via a guide sleeve, a material blocking plate fixed on the guide rod, and a spring fitted on the guide rod. One end of the spring is connected to the mounting plate, and the other end is connected to the spring step on the guide rod.

[0009] Furthermore, the retaining bracket below the cylinder bracket also has a clearance notch, and the side walls on both sides of the clearance notch are provided with "T"-shaped guide grooves. The mounting plate is provided with "T"-shaped connectors on both sides that slide in cooperation with the "T"-shaped guide grooves.

[0010] Furthermore, the bottom of the baffle plate has an arc-shaped structure adapted to the surface of the conveyor belt.

[0011] Furthermore, the bottom of the baffle plate is provided with bristles at equal intervals.

[0012] Furthermore, the power component is a cylinder or an electric cylinder.

[0013] Furthermore, the tiling mechanism includes tiling support rods and tiling plates fixed on the tiling support rods, wherein the bottom of the tiling plate has an arc-shaped structure adapted to the surface of the conveyor belt.

[0014] The beneficial effects of this utility model are:

[0015] 1. Optimized aggregate conveying: The flattening mechanism of this invention can effectively smooth out any piled-up aggregate. This design makes the aggregate distribution on the conveyor belt more uniform, avoiding the problem of insufficient mixing with other materials in subsequent mixing processes due to excessive localized aggregate accumulation, thereby significantly improving the quality stability of asphalt concrete.

[0016] 2. Flexible control of aggregate conveying: The baffle mechanism can flexibly raise or lower the baffle plate via a power unit. In case of abnormal situations such as changes in conveyor belt speed or sudden stops, the baffle plate can be quickly raised to stop the aggregate, effectively preventing it from slipping off the conveyor belt. This not only avoids waste of raw materials and reduces production costs, but also reduces the risk of damage to surrounding equipment caused by slipping aggregate. Furthermore, it eliminates the need for additional manpower and time to clean up slipped aggregate, improving the cleanliness and safety of the working environment.

[0017] 3. Improved equipment stability and durability: Due to the smoothing effect of the paving mechanism on the aggregate, excessive wear on the conveyor belt caused by excessive local accumulation of aggregate is avoided, which helps to extend the service life of the conveyor belt, reduce the maintenance and replacement costs of the equipment, improve the stability and reliability of the entire asphalt concrete mixing plant equipment, and ensure the continuous and efficient operation of production.

[0018] In addition to the objectives, features, and advantages described above, this utility model has other objectives, features, and advantages. The utility model will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

If the specific posture changes, the directional indicators will also change accordingly.

[0025] This utility model provides a material retaining structure for an asphalt concrete mixing plant.

[0026] In this embodiment, refer to Figure 1-3 The asphalt concrete mixing plant retaining structure includes a conveyor belt support 1 and a conveyor belt 2 set on the conveyor belt support 1, as well as a paving mechanism 3 for smoothing out raised aggregates and a retaining mechanism 4 for blocking aggregates.

[0027] The material blocking mechanism 4 includes a material blocking bracket 5 fixed on the conveyor belt support, a cylinder bracket 6 fixed on the material blocking bracket 5, a power component 7 fixed on the cylinder bracket 6, a mounting plate 8 connected to the output end of the power component 7, a guide rod 10 slidably connected to the mounting plate through a guide sleeve 9, a material blocking plate 11 fixed on the guide rod 10, and a spring 12 fitted on the guide rod. One end of the spring is connected to the mounting plate, and the other end is connected to the spring step 13 on the guide rod.

[0028] In the above technical solution, by setting a spreading mechanism and a retaining mechanism on the conveyor belt support, the problem of uneven aggregate distribution on the conveyor belt can be effectively solved, and precise control of aggregate flow can be achieved. The spreading mechanism ensures uniform aggregate distribution, improving the quality of subsequent mixing processes; while the retaining mechanism, driven by a power component, raises and lowers the retaining plate, flexibly blocking or releasing the aggregate flow, thereby ensuring the continuity and controllability of production. In addition, the spring design provides a buffering effect for the retaining plate, enhancing the stability and durability of the system.

[0029] Specifically, the material stop bracket below the cylinder bracket also has a clearance notch 14, and the side walls on both sides of the clearance notch 14 are provided with "T"-shaped guide grooves 15.

This design avoids the baffle plate from shifting or jamming during operation, improving the safety and reliability of the equipment operation, and also facilitating later maintenance and repair work.

[0031] Specifically, the bottom of the baffle plate has an arc-shaped structure that adapts to the surface of the conveyor belt.

[0032] In this embodiment, the bottom of the baffle is designed with an arc-shaped structure that adapts to the surface of the conveyor belt, allowing for a closer fit and effectively preventing aggregate from passing through the bottom of the baffle. This design is particularly suitable for conveyor belt surfaces with slight bends or undulations, ensuring good material blocking even under complex operating conditions, further improving production efficiency and product quality.

[0033] Specifically, the bottom of the baffle plate is provided with bristles 17 at equal intervals.

[0034] In this embodiment, brush bristles are evenly spaced at the bottom of the baffle plate, allowing for cleaning of the conveyor belt surface when material blocking is not required. This keeps the baffle plate surface clean and extends its service life.

[0035] Specifically, the power component is a cylinder or an electric cylinder.

[0036] In this embodiment, the power component can be either a pneumatic cylinder or an electric cylinder, and the user can choose according to their actual needs.

[0037] Specifically, the tiling mechanism includes a tiling support rod 18 and a tiling plate 19 fixed on the tiling support rod 18, wherein the bottom of the tiling plate is an arc-shaped structure adapted to the surface of the conveyor belt.

[0038] In this embodiment, the paving plate in the paving mechanism also adopts an arc-shaped structure design that adapts to the surface of the conveyor belt to ensure that the aggregate can be evenly smoothed over the entire width.
