Abstract
Description
Technical Field
[0001] This invention relates to the field of material conveying equipment technology, specifically to a material conveyor. Background Technology
[0002] Existing material conveying equipment is widely used in mining, building materials, metallurgy, chemical, food, and warehousing logistics. Common forms include belt conveyors, screw conveyors, bucket elevators, and vibrating conveyors. These devices typically only provide conveying in a single direction or for a single process, making it difficult to achieve material screening, temporary storage, quantitative transfer, and multi-channel distribution within a single system. Especially in situations requiring preliminary screening of mixed materials, followed by centralized temporary storage and subsequent directional or graded conveying, existing technologies often necessitate the combined use of multiple independent devices. This not only results in complex system structures and large floor space requirements but also leads to low efficiency in the connection between devices, easily causing material accumulation, blockages, or secondary dust generation.
[0003] Furthermore, existing material handling systems often rely on manual forklifts or simple lifting mechanisms to transfer storage containers, resulting in low automation levels. This makes it difficult to accurately grasp, stably lift, and adjust the position of storage structures, especially in multi-station, multi-outlet scenarios, where it's challenging to guarantee the continuity and reliability of material transport. Additionally, traditional material distribution methods largely depend on fixed guide chutes or manual channel switching, lacking flexibility and unable to dynamically allocate materials according to actual production needs.
[0004] Therefore, there is an urgent need for a material conveyor with high structural integration and multiple functions that can realize conveying, screening, temporary storage, vertical transfer and distribution on the same equipment, so as to solve the problems of system complexity, low efficiency and insufficient automation in the existing technology.

[0016] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0017] Please see Figure 1-5 The present invention provides a technical solution: A material conveyor includes a first conveying structure, a screening structure, a horizontal transfer structure, a storage structure, a vertical transfer structure, a distribution structure, and two second conveying structures. The first conveying structure has a screening structure on its side. The first conveying structure includes two uprights 1, with guide frames 2 connected to the tops of the two uprights 1. A power motor 3 is installed on the outer wall of the guide frame 2, and a conveyor belt 4 is installed inside the guide frame 2. The screening structure includes a frame 5, with two... The casting blocks 6 are arranged symmetrically on both sides. Guide rods are inserted into the sides of the casting blocks 6. The inner sides of the two guide rods are connected to the screening frame 7. The screening frame 7 is equipped with a screen 8 on its inner side. The screening frame 7 is located directly below the transmission end of the conveying structure. The horizontal transfer structure includes a horizontal guide plate 9. An electromagnetic guide rail 10 is provided on the guide plate 9. A movable plate 11 is slidably connected to the electromagnetic guide rail 10. A storage column 12 is provided on the top of the movable plate 11. A storage structure is placed on the storage column 12.
[0018] The vertical transfer structure includes two support plates 13 symmetrically distributed on both sides of the guide plate 9. Two vertical steering plates 14 are installed at the top of the support plates 13. A lifting motor 15 is installed on the outer side of the steering plates 14, and a guide groove is formed on the inner wall of the steering plates 14. A transmission chain is installed on the guide groove. The lifting motor 15 drives the transmission chain. A linkage frame plate 16 is connected to the outer side of the transmission chain. A suspension plate 17 is connected to the top of the outer side of the linkage frame plate 16. A mounting block is detachably connected to the outer side of the suspension plate 17. A hydraulic cylinder 18 is connected to the outer side of the mounting block. The output end of the hydraulic cylinder 18 is connected to a clamping plate 19. By replacing the traditional single-point lifting method with a chain-guided lifting structure, the stability during vertical transfer is significantly improved. The cooperation between the clamping plate and the protruding strips on the outer wall of the storage cylinder effectively prevents the storage structure from shaking or falling off during lifting, improving operational safety and reliability.
[0019] The material distribution structure includes four support rods 20, symmetrically distributed on both sides of the electromagnetic slide rail one. The tops of two support rods 20 are connected to a guide frame 21. An electromagnetic slide rail two is installed on the inner wall of the guide frame 21. A moving plate 22 is slidably connected to the outer side of the electromagnetic slide rail two. Vertical plates 23 are symmetrically arranged on both sides of the bottom of the moving plate 22. A hydraulic cylinder two 24 is installed on the inner wall of the vertical plate 23. The output end of the hydraulic cylinder two 24 is connected to a clamping plate two 25. The material distribution position can be flexibly adjusted according to actual production needs, realizing multi-channel, controllable material distribution operations. Compared with a fixed material guiding structure, this significantly improves the flexibility and adaptability of material distribution and reduces equipment modification costs.
[0020] The second material conveying structure includes two sloping guide frames 26, symmetrically positioned on either side of the guide frame 21. A vibrating motor 27 is installed on one outer wall of each guide frame. A screen plate 28 with several screen holes is installed on the discharge chute of the guide frame 26. This effectively prevents material accumulation or blockage during the distribution process, improving the uniformity of the discharge. The screen plate further enhances the particle size control capability, which is beneficial for improving the consistency of the finished product.
[0021] A buckle plate 29 is located between the outer walls of the two adjusting plates 14. A seat plate 30 is located on the outer side of the buckle plate 29. Two hydraulic cylinders 31 are mounted on the seat plate 30. The output ends of the hydraulic cylinders 31 are connected to the bottom of the guide frame 26. By adjusting the angle of the guide frame 26 with the hydraulic cylinders 31, materials with different flow characteristics can be accommodated, enhancing the equipment's adaptability to various working conditions and improving the continuity and stability of material distribution and conveying.
[0022] The storage structure includes a storage cylinder 32, which has an open top and several protrusions 33 on its outer wall. A clamping plate 19 has slots corresponding to the protrusions 33. An annular protrusion 34 is located at the top of the storage cylinder 32, and an openable discharge end cover 35 is located on the bottom inner side of the storage cylinder 32. The protrusions and the slots of the clamping plate 1 cooperate to improve clamping reliability; the annular protrusion facilitates quick positioning of the storage cylinder within the receiving column; and the openable discharge end cover facilitates quantitative and controllable discharge, reducing material waste.
[0023] A hydraulic cylinder 36 is installed on the inner wall of the steering plate 14. The output end of the hydraulic cylinder 36 is connected to a functional plate. A liquid storage tank 37 is installed on the inner wall of the functional plate. The output end of the liquid storage tank 37 is connected to a bent guide pipe 38. Depending on the usage requirements, the material or conveying environment can be sprayed, lubricated, or dust suppressed to improve the working environment. Simultaneously, the flowability of the material during conveying and distributing is improved, further enhancing the stability and applicability of the entire machine.
[0024] In the workflow, materials are initially conveyed by the conveying structure 1. The power motor 3 drives the conveyor belt 4 to operate continuously, causing the material to move along the guide frame 2. When the material reaches the end of the conveyor, it falls freely into the screening structure 7 located directly below. The screening frame 7 remains stable under the guidance of the guide rods, and the screen 8 performs preliminary screening of the material. Material that meets the particle size requirements passes through the screen 8 and falls into the area below, while material that does not meet the requirements continues to be discharged along the screening frame 7, thus completing the first screening process.
[0025] The screened material enters the horizontal transfer structure. Guided and driven by the electromagnetic guide rail 10, the movable plate 11 moves along the guide plate 9, causing the top receiving column 12 and the overall storage structure to move horizontally, realizing the horizontal transfer of material between different workstations. When the storage structure moves below the vertical transfer structure, the control system starts the lifting motor 15, driving the transmission chain to rotate, causing the linkage plate 16 and suspension plate 17 to move up and down along the adjusting plate 14.
[0026] Hydraulic cylinder 18 drives clamping plate 19 to close, cooperating with the protrusion 33 on the outer wall of storage cylinder 32 to achieve stable clamping of the storage structure. After clamping is completed, the storage structure is lifted to a predetermined height, and then it can be transferred to the top of the distribution structure through a combination of horizontal or vertical movements.
[0027] During the material distribution process, the moving plate 22 moves laterally under the action of the electromagnetic slide rail 2, and the hydraulic cylinder 24 drives the clamping plate 25 to limit and control the material storage structure or its discharge end. Then, the discharge end cover 35 at the bottom of the storage cylinder 32 is opened, and the material falls into the guide frame 26 under the action of gravity. After the vibrating motor 27 is started, it generates a vibration effect on the guide frame 26, so that the material is evenly dispersed and conveyed forward along the slope structure. At the same time, it is screened again by the screening plate 28, and finally conveyed to different discharge directions.
[0028] In addition, hydraulic cylinder 31 is used to adjust the attitude angle of guide frame 26 to adapt to different material flow characteristics; hydraulic cylinder 4 36 and its connected functional plate and liquid storage tank 37 can spray, lubricate or suppress dust on materials or conveying environment as needed, further improving the applicability and reliability of the equipment.

It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics.
