Description

Technical Field

[0001] This application relates to the field of sand and gravel processing technology, and in particular to a feeding device for sand and gravel processing. Background Technology

[0002] With the continuous advancement of urbanization, the demand for sand and gravel in various infrastructure construction projects such as housing, roads, bridges, and water conservancy has increased dramatically, and the demand for sand and gravel aggregates has also continued to grow. However, natural sand resources are limited, and the mining process can easily damage the ecological environment. Therefore, the supply of natural sand is far from meeting the ever-increasing market demand. Artificial sand production refers to the use of mechanical equipment to process raw materials such as mountain rocks and river pebbles dug from riverbeds through crushing, screening, and other processes to produce sand and gravel suitable for construction. Due to its resource advantages, quality controllability, environmental protection and energy saving, as well as policy support, artificial sand and gravel has gradually replaced natural sand and has become one of the indispensable building materials in the market.

[0003] With the continuous advancement of mechanical manufacturing technology, sand making equipment has also developed rapidly. Traditional fixed screening equipment can no longer meet the large-scale and rapidly changing market demands in terms of flexibility, efficiency, and cost. Tracked mobile screening stations, with their high flexibility, portability, rapid deployment capability, efficient and accurate screening capability, and low operating costs, have become the main equipment for artificial sand and gravel processing. However, in the process of sand and gravel processing, excavators or loaders are often needed to load and transport the blasted raw materials or stockpiled raw materials to the feed inlet of the crushing and screening station. However, this method relies on manual operation of the equipment, resulting in low automation and poor equipment coordination, leading to relatively low overall production efficiency. In addition, the equipment and labor costs are high, and dust pollution is easily generated during the feeding process, which can have an adverse effect on the health of workers.

[0009] Optionally, in some embodiments, the outer wall of the conveyor belt 16 is uniformly distributed with raised strips 18.

[0010] Optionally, in some embodiments, baffles 19 are provided on both sides of the horizontal support frame 11, at the end of the horizontal support frame 11 away from the inclined support frame 12, and on both sides of the inclined support frame 12.

[0012] Optionally, in some embodiments, the transmission assembly includes a transmission sprocket 26 fixedly sleeved on a rotating shaft, a transmission shaft 24 fixedly connected to one end of the power roller 13, a driven sprocket 25 fixedly sleeved on the transmission shaft 24, and a chain 27 drivingly connecting the transmission sprocket 26 and the driven sprocket 25.

[0013] The technical solution provided in this application may include the following beneficial effects:

[0014] 1) This application is used to connect with the existing tracked crushing and screening station. By integrating the shoveling mechanism and the climbing conveying mechanism on the same mounting frame and equipping them with a unified power mechanism, the complexity of manual intervention and equipment coordination is reduced, forming a continuous and efficient feeding process. This improves the automation level of the overall production process. The automated delivery of sand and gravel raw materials to the feed inlet of the tracked crushing and screening station significantly improves production efficiency, reduces efficiency losses caused by improper manual operation or poor equipment coordination, reduces dependence on operators, and lowers labor and equipment costs.

[0015] 2) By setting up horizontal support frames and inclined support frames, and with the coordinated action of power rollers, lower pressure rollers, driven rollers, upper pressure rollers and conveyor belts, this application can smoothly transport materials from a lower horizontal position to a higher position and dump them into the feed inlet of the track crushing and screening station, providing a reliable climbing path for the materials and ensuring the stability and smoothness of the materials during the conveying process.

[0016] 3) This application effectively increases the adhesion between the conveyor belt and the sand and gravel raw materials by evenly distributing the raised strips on the outer wall of the conveyor belt, preventing the materials from slipping or deviating during the climbing process, thereby improving the conveying efficiency and safety. By setting baffles, it effectively prevents the materials from overflowing from both sides during the conveying process, ensuring that the materials can be conveyed along the predetermined path, further improving the conveying safety.

[0017] 4) This application drives the rotating shaft to rotate via a drive motor, and then transmits the power to the power roller through a transmission component, thereby driving the inclined conveying mechanism. At the same time, the rotation of the rotating shaft also drives the drive gear to rotate, which in turn drives the gear ring at the outer end of the rotating frame to rotate, thereby driving the shoveling mechanism. By providing power to both the shoveling mechanism and the inclined conveying mechanism through a single power mechanism, the power system of the entire feeding device for sand and gravel processing is simplified. This not only reduces the complexity and cost of the equipment, lowers energy consumption, and improves energy utilization efficiency, but also improves the reliability and maintainability of the system.

[0029] To address the aforementioned issues, this application provides a feeding device for sand and gravel processing, which can improve production efficiency, reduce efficiency losses caused by improper manual operation or poor equipment coordination, reduce reliance on operators, and lower labor and equipment costs.

[0030] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0031] See Figure 1-2 The feeding device for sand and gravel processing includes a mounting frame 1, a shovel mechanism 2 at the front end of the mounting frame 1, and a climbing conveyor mechanism 28 on the mounting frame 1. The bottom end of the climbing conveyor mechanism 28 is located below the discharge port 3 on the shovel mechanism 2. The mounting frame 1 is also equipped with a power mechanism 4 for driving the shovel mechanism 2 and the climbing conveyor mechanism 28. The power mechanism 4 is connected to drive the shovel mechanism 2 and the climbing conveyor mechanism 28 respectively.

[0032] The material shoveling mechanism 2 includes a fixed cylinder 5, with both sides of the fixed cylinder 5 connected to the front end of the mounting frame 1. A rotating frame 6 is rotatably mounted on the outer periphery of the fixed cylinder 5. Buckets 7 are evenly distributed around the circumference of the rotating frame 6. The side of the buckets 7 connected to the rotating frame 6 is open. A feed inlet 8 is opened at the top of the outer periphery of the fixed cylinder 5. A discharge outlet 3 is arranged on the side of the fixed cylinder 5 near the climbing conveyor mechanism 28. The feed inlet 8 and the discharge outlet 3 are connected. The rotating frame 6 is driven and connected to the power mechanism 4.

[0033] During operation, the feeding device of this application can be connected to the existing tracked crushing and screening station through the connecting frame. The walking and rotating movement of the feeding device is driven by the walking and rotating movement of the tracked crushing and screening station. The bottom of the mounting frame 1 can also be equipped with the existing walking mechanism and rotating mechanism. The number of hoppers can be determined according to the actual situation.

[0034] The shoveling mechanism 2, power mechanism 4, and inclined conveying mechanism 28 are integrated on the same mounting frame 1. The power mechanism 4 provides power to both the shoveling mechanism 2 and the inclined conveying mechanism 28, thereby driving multiple buckets 7 to rotate and perform shoveling operations. The material shoveled by the buckets 7 is poured into the feed inlet 8 at the top of the outer periphery of the fixed cylinder 5, and then falls from the discharge outlet 3 on the side of the fixed cylinder 5 onto the inclined conveying mechanism 28, and is then transported to the feed inlet of the tracked crushing and screening station at the designated location. The entire feeding process is continuous and efficient, reducing the complexity of manual intervention and inter-equipment coordination, thereby improving the automation level of the overall production process, significantly improving the production efficiency of sand and gravel, reducing efficiency losses caused by improper manual operation or poor equipment coordination, reducing dependence on operators, and lowering labor and equipment costs.

[0035] In some embodiments, the rotating frame 6 includes two symmetrically arranged rotating rings 9 and a connecting rod 10 connecting the two rotating rings 9. The rotating rings 9 are rotatably connected to the fixed cylinder 5 and are symmetrically arranged on both sides of the fixed cylinder 5.

[0036] During operation, the power mechanism 4 drives the rotating ring 9 to rotate, which in turn drives the bucket 7 mounted on it to rotate. The material scooped up by the bucket 7 is poured into the feed inlet 8 at the top of the outer periphery of the fixed cylinder 5, and then falls from the discharge outlet 3 on the side of the fixed cylinder 5 into the climbing conveyor mechanism 28, and is then transported to the feed inlet of the tracked crushing and screening station at the designated location.

[0037] In some implementations, see Figure 3 The inclined conveying mechanism 28 includes a horizontal support frame 11 located below the discharge port 3, an inclined support frame 12 connected to the end of the horizontal support frame 11, a power roller 13 rotatably connected to the end of the horizontal support frame 11 away from the inclined support frame 12, a driven roller 14 rotatably connected to the end of the inclined support frame 12 away from the horizontal support frame 11, a lower pressure roller 15 rotatably connected at the connection between the horizontal support frame 11 and the inclined support frame 12, a conveyor belt 16 sleeved between the power roller 13, the lower pressure roller 15 and the driven roller 14, and upper pressure rollers 17 located at both ends above the lower pressure roller 15 and rotatably connected to the connection between the horizontal support frame 11 and the inclined support frame 12; the horizontal support frame 11 and the inclined support frame 12 are mounted on the mounting frame 1, and the upper pressure rollers 17 press on the conveyor belt 16.

[0038] In some embodiments, the outer wall of the conveyor belt 16 is uniformly distributed with raised strips 18.

[0039] During operation, the convex strip 18 increases the adhesion between the conveyor belt 16 and the sand and gravel raw materials, preventing the materials from slipping or deviating during the climbing process, thereby improving conveying efficiency and safety.

[0040] In some embodiments, baffles 19 are provided on both sides of the horizontal support frame 11, at the end of the horizontal support frame 11 away from the inclined support frame 12, and on both sides of the inclined support frame 12. An inclined downward discharge cylinder 20 is provided on the discharge port 3. The bottom of the discharge port 3 is inclined downward. The discharge cylinder 20 passes through the baffle 19 on one side of the horizontal support frame 11 and is located on the upper side of the conveyor belt 16 on the horizontal support frame 11.

[0041] During operation, the baffle 19 prevents materials from overflowing from both sides during the conveying process, ensuring that the materials can be conveyed along the predetermined path.

[0042] In some embodiments, the power mechanism 4 includes a gear ring 21 fixedly connected to the outer end of one side of the rotating frame 6, a drive gear 22 meshing inside the gear ring 21, and a drive motor 23 mounted on the mounting frame 1 via a fixed base. A rotating shaft is connected between the output end of the drive motor 23 and the drive gear 22, and a transmission assembly is connected between the rotating shaft and the power roller 13. The transmission assembly includes a transmission sprocket 26 fixedly sleeved on the rotating shaft, a transmission shaft 24 fixedly connected to one end of the power roller 13, a driven sprocket 25 fixedly sleeved on the transmission shaft 24, and a chain 27 drivingly connecting the transmission sprocket 26 and the driven sprocket 25.

[0043] During operation, the drive motor 23 is a prior art technology. The drive motor 23 serves as a power source, converting electrical energy into mechanical energy. The output end of the drive motor 23 is connected to the drive gear 22 via a rotating shaft. When the motor starts, the rotating shaft drives the drive gear 22 to rotate, which in turn drives the gear ring 21 meshing with the drive gear 22 to rotate. Under the drive of the gear ring 21, the rotating frame 6 begins to rotate, which in turn drives multiple buckets 7 evenly distributed around its circumference to perform shoveling operations. At the same time, the rotating shaft also drives the transmission sprocket 26 on it to rotate, which in turn drives the driven sprocket 25 to rotate through the transmission of the chain 27, which in turn drives the power roller 13 to rotate through the transmission shaft 24 to drive the climbing conveyor mechanism 28. One set of power mechanism 4 provides power to both the shoveling mechanism 2 and the climbing conveyor mechanism 28, simplifying the power system of the entire sand and gravel processing feeding device. This not only reduces the complexity and cost of the equipment, lowers energy consumption, and improves energy utilization efficiency, but also improves the reliability and maintainability of the system.
