Description

Technical Field

[0001] The utility model belongs to the technical field of material conveying equipment, and specifically relates to a bulk material conveying device. Background Art

[0002] The working principle of a screw conveyor is that the rotating screw blades push the material for conveying. The forces that prevent the material from rotating with the screw blades of the screw conveyor are the self-weight of the material and the frictional resistance of the casing of the screw conveyor to the material. The screw blades are welded on the rotating shaft of the screw conveyor. The surface shape of the blades has various types such as solid surface shape, belt surface shape, and blade surface shape according to different conveyed materials.

[0003] After the screw blades of the screw conveyor are used for a long time, different degrees of wear will appear on their surfaces, and it is necessary to remove the entire conveying device for maintenance or replacement, which has a large labor intensity. If only part of the surface of the replaced screw blades is worn, replacing the whole is a waste of resources and has low environmental protection. Content of the Utility Model

Two sets of sleeves 5 are rotatably connected to the first housing 1 and the second housing 2, located on both side walls of the first housing 1 and the second housing 2;

[0028] A mounting shaft 6 is threadedly connected between the two sets of sleeves 5, and an array of spiral conveying blades 7 located between the two sets of sleeves 5 is provided on the mounting shaft 6;

[0029] One end of the array of spiral conveying blades 7 is provided with a placement groove 8, a magnetic attraction block 9 is provided in the placement groove 8, and the other end of the spiral conveying blade 7 is provided with an attraction block 10 corresponding to the magnetic attraction block 9.

[0030] When this embodiment is in use, the two sets of sleeves 5 are installed at both ends of the mounting shaft 6, and the sleeves 5 and the mounting shaft 6 are threadedly connected. Install one set of sleeves 5, and sleeve the array of spiral conveying blades 7 on the mounting shaft 6. Since one end of the spiral conveying blade 7 is provided with a placement groove 8 and the other end is provided with an attraction block 10, therefore, the attraction block 10 of the adjacent spiral conveying blade 7 cooperates with the placement groove 8, and a magnetic attraction block 9 is provided in the placement groove 8, which can attract the attraction block 10. After all the spiral conveying blades 7 are correspondingly installed, install the sleeve 5 at the other end of the mounting shaft 6. Under the action of the two sets of sleeves 5, ensure that the spiral conveying blades 7 are locked on the mounting shaft 6;

[0031] The two sets of sleeves 5 are rotatably connected between the first housing 1 and the second housing 2, and they can be detachably connected by screws;

[0032] When conveying materials, the materials enter between the first housing 1 and the second housing 2 through the feed pipe 3, and the power device drives the sleeve 5 to rotate, driving the spiral conveying blade 7 to rotate, and conveying the materials out through the discharge pipe 4;

[0033] If the blades of one set or several sets of spiral conveying blades 7 are severely worn, disassemble the first housing 1 and the second housing 2, remove the damaged spiral conveying blades 7, and replace them with new spiral conveying blades 7, avoiding the waste phenomenon caused by disassembling the entire shaft;

[0037] A sealing strip cooperating with the installation block 12 is provided on the inner side wall of the installation groove 11;

[0038] Two groups of installation grooves 11 are provided on the first housing 1, which are respectively located on both sides of the feed pipe 3.

[0039] When this example is in use, when installing the first housing 1 and the second housing 2, align the installation block 12 with the installation groove 11, rotate the adjusting screw 17 with the aid of tools, and the auxiliary plate 15 threadedly connected thereto moves along the guiding column 16, so that the locking block 13 cooperates with the locking groove 14, thereby achieving the purpose of locking the first housing 1 and the second housing 2;

[0040] The installation steps are simple, the disassembly is convenient, the installation efficiency is improved, and it is convenient to replace the screw conveyor blade 7.

[0041] Example 3. On the basis of Example 2, the feed pipe 3 is located near one group of sleeves 5 and is arranged corresponding to the screw conveyor blade 7 near one group of sleeves 5, and the discharge pipe 4 is located near the other group of sleeves 5 and is arranged corresponding to the screw conveyor blade 7 near the other group of sleeves 5.

[0042] When this example is in use, during feeding, it enters the screw conveyor blade 7 near one group of sleeves 5 through the feed pipe 3, and during discharging, it enters the screw conveyor blade 7 near the other group of sleeves 5 through the feed pipe 3, ensuring that there is no material accumulation at both ends of the first housing 1 and the second housing 2.

[0043] Example 4. On the basis of Example 3, gaskets are provided between the two groups of sleeves 5 and the screw conveyor blades 7.
