Technical Field

[0001] This utility model relates to the field of engineering machinery, and in particular to a self-driven wheeled batching conveyor. Background Technology

[0002] Currently, belt conveyors are the most important equipment for conveying and unloading bulk materials at large construction sites. They are widely used in mining, metallurgy, building materials, chemical, power, and food processing industries. Belt conveyors are widely used in coal mines, metal mines, steel companies, ports, and cement plants. These conveyor machines can transport not only bulk materials but also packaged materials. However, their design and application vary significantly depending on the location, working environment, and type of material being conveyed. Batching conveyors are a type of belt conveyor. They transport raw materials such as stones, sand, and boulders via belt conveyors to the main unit, where they are mixed according to the material ratio set by the batching machine to obtain the finished product. They are generally suitable for the batching and mixing of various materials in ports, coal mines, and mixing plants.

[0003] Existing batching conveyors are bulky and inconvenient to move around in complex terrain, resulting in low work efficiency. Therefore, a self-driven wheeled batching conveyor is needed. Utility Model Content

However, it should be noted that many details listed in the specification are merely to provide the reader with a thorough understanding of one or more aspects of this utility model, and these aspects can be achieved even without these specific details.

[0027] like Figure 1-2 As shown, a self-driven wheeled batching conveyor includes a frame 1, a material bin 2, a main conveyor 3, and a hammer crusher 4. The hammer crusher 4 is located at the front end of the frame 1 and is used to mix materials. A finished product conveyor 5 is located below the discharge port of the hammer crusher 4 and is used to transport the finished material. The material bin 2 is located in the middle of the frame 1 and is used to hold materials of different specifications (0-80mm). A belt scale conveyor 6 is located below the material bin 2 and is used to weigh the materials. The main conveyor 3 is located below the belt scale conveyor 6 and is used to transport the materials falling from the belt scale conveyor 6 to the hammer crusher 4. The discharge end of the main conveyor 3 extends to the inlet of the hammer crusher 4. Drive wheels 7 are respectively provided at the lower parts of the front and rear ends of the frame 1. The drive wheels 7 can both move and turn on the spot.

[0028] In this embodiment of the invention, four material bins 2 are arranged sequentially from front to back on the frame 1 and connected to the frame 1. The discharge ports of the material bins 2 are located above the belt conveyors 6. Four belt conveyors 6 are also arranged, each located below the discharge port of a material bin 2 and connected to the frame 1. A loader loads materials of different specifications into the four material bins 2, and the materials in the bins 2 fall onto the belt conveyors 6 below through their material outlets. The four belt conveyors 6 have their speeds adjusted and are proportionally proportioned via an electrical control box 9. All the materials on the four belt conveyors 6 fall onto the main conveyor 3, which then transports them to the hammer crusher 4.

[0029] like Figure 3 As shown, a hydraulic station 8 is installed between the hammer crusher 4 and the material bin 2. The hydraulic station 8 is connected to the frame 1 and is positioned above the main conveyor 3. A power assembly 10 is installed at the rear end of the frame 1, providing power to drive the hydraulic station 8 and subsequently drive the drive wheels 7 to move or steer. A spray water tank 11 is installed between the hydraulic station 8 and the material bin 2, and is connected to the frame 1. Water pipes can be installed in dusty areas for dust removal, and the water pipes are connected to the spray water tank 11. An electrical control box 9 is installed on one side below the hydraulic station 8 and is connected to the frame 1. The electrical control box 9 controls the start and stop of the equipment, and a frequency converter 12 is installed on one side of the electrical control box 9.

[0030] like Figure 1 and Figure 4-6As shown, the lower front part of the frame 1 is provided with three sets of drive wheels 7, and the lower rear part of the frame 1 is provided with two sets of drive wheels 7. The drive wheels 7 are connected to the frame 1 through a slewing bearing 13. The inner ring of the slewing bearing 13 is connected to the frame 1, and the outer ring of the slewing bearing 13 is connected to the drive wheels 7. The outer circumferential surface of the outer ring of the slewing bearing 13 is configured as a helical gear structure. A worm gear 14 is meshed with the outer ring of the slewing bearing 13. One end of the worm gear 14 is connected to a rotary hydraulic motor 15, and the output end of the rotary hydraulic motor 15 is connected to the worm gear 14. A sensor 16 is provided at the other end of the worm gear 14. The sensor 16 measures the rotational speed and controls the speed and rotation angle. The drive wheel 7 includes two wheels 17 connected by a wheel axle 18. A connecting shaft 19 is connected to the middle of the wheel axle 18, and the upper end of the connecting shaft 19 is connected to the outer ring of the slewing bearing 13 via a connecting piece 20. The connecting piece 20 can be a circular plate with a hole in the middle. A travel hydraulic motor 21 is provided at one end of the wheel axle 18. The wheel axle 18 and the connecting shaft 19 are hollow shafts to facilitate the installation of hydraulic pipelines, etc. When turning, the slewing hydraulic motor 15 drives the worm gear 14 to rotate, which in turn drives the outer ring of the slewing bearing 13 to rotate, causing the drive wheel 7 to rotate accordingly, thus achieving the slewing function. Then, the travel hydraulic motor 21 directly drives the wheel axle 18 to rotate, and the two wheels 17 follow the rotation of the wheel axle 18, thus achieving the travel function. This facilitates relocation and improves work efficiency.

[0031] Working principle

[0032] Four different specifications of materials are loaded into four material bins 2 by a forklift. The materials fall from the material outlet of the material bins 2 onto the belt conveyor 6 below. The four belt conveyors 6 are used to mix the materials in proportion. Then all the materials on the four belt conveyors 6 fall onto the main conveyor 3 and are transported to the hammer crusher 4. The hammer crusher 4 mixes the materials to obtain the finished product. Finally, the finished product conveyor 5 transports the finished product out.

[0033] During relocation, the worm gear 14 can be driven to rotate by the rotary hydraulic motor 15. The worm gear 14 drives the outer ring of the slewing bearing 13 to rotate, causing the drive wheel 7 to rotate accordingly. Then, the walking hydraulic motor 21 directly drives the wheel axle 18 to rotate, and the two wheels 17 follow the wheel axle 18 to rotate, thereby realizing the straight or lateral movement of the batching conveyor.

[0034] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
