Description

Technical Field

[0001] This utility model relates to the technical field of granite crushing equipment, specifically a four-section multi-stage roller pressing structure for granite crushing. Background Technology

[0002] Granite is a common type of igneous rock in geology, belonging to the category of plutonic rocks. Its main mineral components include quartz, feldspar, and mica. Quartz is mostly transparent or white, giving granite its exceptional hardness; feldspar comes in various colors, including pink, white, or gray, becoming a key factor in determining the overall color tone of the rock; mica is mainly black or brown, adding a unique luster and texture to granite. Through the synergistic effect of these different minerals, granite possesses many significant advantages, including both hardness and aesthetic appeal, and is therefore widely used in architecture, decoration, sculpture, and many other fields.

[0003] In existing granite crushing processes, to achieve more efficient multi-stage crushing and fine processing of granite edges, multiple sets of crushing rollers of different specifications are usually added inside the crushing box to achieve multi-stage crushing. However, after long-term use, the surfaces of these multiple sets of crushing rollers of different specifications will wear, peel off, or even break, requiring frequent shutdowns for replacement, which affects production efficiency. Moreover, the narrow crushing box space increases the difficulty of replacing and maintaining the crushing rollers. In order to improve the replacement efficiency of the crushing rollers and reduce the difficulty of replacement and maintenance, this application proposes a four-stage multi-stage roller pressing structure for granite crushing. Utility Model Content

Multiple pallet hydraulic rods 803 are symmetrically fixedly connected to both sides of the upper surface of the pallet mounting plate 801 near the end of the pallet baffle 802. A pallet 804 is fixedly connected to the top of the multiple pallet hydraulic rods 803. By setting the pallet baffle 802, the box can be blocked when crushing granite to prevent the crushed debris from splashing out of the crushing box 1 and affecting the crushing effect.

[0023] The crushing box 1 includes a box body 101. Multiple rectangular openings 102 are vertically and evenly spaced at both ends of one side of the box body 101. A discharge pipe 103 is fixedly connected to one end of the bottom of the box body 101. Multiple feet 104 are symmetrically fixedly connected to both sides of the bottom of the box body 101. By setting multiple rectangular openings 102, it is convenient to install the hydraulic moving component 5 and the hydraulic pallet component 8, and to disassemble and assemble the crushing roller component 7, thereby reducing the difficulty of disassembly and assembly.

[0024] The material feeding hopper 2 is fixedly connected to one end of the top of the box 101. Multiple mounting plates 3 are fixedly connected to the box 101 below multiple rectangular openings 102. One side of the protective door 4 is rotatably connected to the box 101, and the other side of the protective door 4 is connected to the box 101 by bolts.

The outer side of the roller plate 501 is movably attached to the top of the rectangular opening 102. The other ends of the two roller hydraulic rods 502 are fixedly connected to the box 101 at both ends of the rectangular opening 102. By setting the protective door 4, both ends of the box 101 can be opened to facilitate the disassembly and assembly of the crushing roller component 7.

[0025] The feeding baffle component 10 includes two material baffles 1001, which are inclined from one top end to the other bottom end. The top of the material baffles 1001 is fixedly connected to the inner side of the box 101 at both ends of the transfer roller plate 501, and the bottom of the material baffles 1001 is located above the transfer roller plate 501. The bottom of the two lowest material baffles 1001 is fixedly connected to both ends of the discharge pipe 103. By setting the feeding baffle component 10, it is convenient to transport the crushed granite material and perform multiple finer crushing processes.

The electric linear guide rail 601 is fixedly connected to the upper surface of the mounting plate 3. The crushing roller component 7 includes a roller body 701. Two roller mounting sleeves 702 are movably engaged at both ends of the roller body 701 through the housing 101 and the roller transfer plate 501, respectively. A crushing outer ring 703 is connected to the outside of the roller body 701 by screws. The two roller mounting sleeves 702 are connected to both ends of the roller body 701 by screws. The roller mounting sleeves 702 are rotatably connected to the housing 101 and the roller transfer plate 501, respectively. By setting the roller mounting sleeves 702, it is easy to quickly fix both ends of the roller body 701, thereby improving the efficiency of disassembly and assembly and reducing the difficulty of disassembly and assembly.

[0027] The lower surface of the pallet mounting plate 801 is fixedly connected to multiple electric sliders 602. The outer side of the pallet baffle 802 is movably fitted to the lower part of the rectangular opening 102. The gear transmission component 9 includes a gear motor 901. The output end of the gear motor 901 is fixedly connected to a drive gear 902. The gear motor 901 is fixedly connected to the housing 101.

The inner side of the first driven gear 903 is fixedly connected to a roller mounting sleeve 702 on one roller body 701. The inner side of the second driven gear 904 is fixedly connected to a roller mounting sleeve 702 on another roller body 701. By setting the gear transmission component 9, the crushing outer rings on the two roller bodies 701 can be driven to rotate in opposite directions, thereby crushing the granite.

[0028] Working principle: Granite is fed into the crushing box 1 through the feeding hopper 2. Multiple gear motors 901 drive the drive gear 902 to rotate, which in turn drives the first driven gear 903 and the second driven gear 904 to rotate. This causes the first driven gear 903 and the second driven gear 904 to drive the two roller mounting sleeves 702 on them to rotate, which in turn causes the crushing outer rings 703 on the outer sides of the two roller bodies 701 to rotate in opposite directions, crushing the granite. The crushed granite is then conveyed through two material baffles 1001 to the finer crushing roller component 7 at the bottom for further crushing, and finally discharged through the discharge pipe 103. When it is necessary to replace or maintain the crushing roller component 7, loosen the screws on the roller body 701 and one end of the roller mounting sleeve 702 of the gear transmission component 9. The two electric linear guides 601 drive the push plate mounting plate 3 on the top of the multiple electric sliders 602 to move, thereby moving the support plate 804 to the bottom of the crushing roller component 7. The multiple support plate hydraulic rods 803 drive the push plate to lift up, thereby supporting the bottom of the crushing roller component 7. The two moving roller hydraulic rods 502 drive the moving roller plate 501 to move. The electric guide rail component 6 drives the hydraulic support plate component 8 to move, pulling the crushing roller component 7 out of the crushing box 1. Open the two protective doors 4, disconnect the roller body 701 from the roller mounting sleeve 702 at one end of the moving roller plate 501, and then replace the new roller body 701 and the crushing outer ring 703. Then, send the roller body 701 into the crushing box 1 and insert it into the roller mounting sleeve 702 at the other end to complete the replacement and maintenance.

[0029] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
