Description

Technical Field

[0001] The utility model relates to the technical field of spiral chutes, in particular to an adjustable spiral chute. Background Art

[0002] The spiral chute is a mineral sorting equipment based on the principle of gravity sorting. It mainly utilizes the movement of materials on the spiral trough surface, combined with the differences in material density, particle size and shape, through gravity, centrifugal force and the design of the spiral trough, to promote the separation of materials of different densities during the flow process. It is widely used in the sorting and recovery of minerals. The spiral chute in the prior art connects multiple groups of fixed barrels through a threaded groove, which facilitates the assembly of the spiral chute. However, when sorting different types of materials, if the height of the side guard plate is too low, the material will easily overflow from the trough. If the height of the side guard plate is too high, it will affect the flow of the material, resulting in material accumulation or uneven flow rate. At this time, it is necessary to replace spiral chutes of different sizes to adapt to different types of materials. The operation is cumbersome, which increases the workload of the staff and is not convenient for the use of the spiral chute. Therefore, it needs to be improved. Utility Model Content

[0028] Embodiment 2

[0029] See also Figure 2 , Figure 5-7 The base 1, the first fixed cylinder 6, the second fixed cylinder 7 and the third fixed cylinder 8 are all provided with a through hole 14 on the inner side, the sleeve 2 and the connecting rod 4 are slidably connected to the inner side of the through hole 14, and the outer surface of the sleeve 2 and the connecting rod 4 are provided with a mounting hole 22 on one side.

[0030] Working principle: When the spiral chute needs to be assembled, first rotate the first fixed cylinder 6 into the inner side of the support block 3 through the thread groove 12, and then rotate the second fixed cylinder 7 into the inner side of the first fixed cylinder 6 through the thread groove 12, and at the same time align the block 16 of the spiral sheet 10 on the second fixed cylinder 7 with the slot 15 on the spiral sheet 10 of the first fixed cylinder 6 and insert it, then the assembly of the first fixed cylinder 6 and the second fixed cylinder 7 is completed, and the assembly quantity of the second fixed cylinder 7 can be selected according to actual needs. Similarly, the assembly of the second fixed cylinder 7 and the third fixed cylinder 8 can be completed, and the sealing ring 9 can improve the sealing of the connection between the first fixed cylinder 6, the second fixed cylinder 7 and the third fixed cylinder 8, then insert the connecting rod 4 into the inner side of the sleeve 2 through the through hole 14, and insert the connecting block 5 into the inner side of the third fixed cylinder 8 through the connecting rod 4, and then move the connecting rod 4 to a suitable position in the through hole 14 and the inner side of the sleeve 2 , the second threaded rod 23 can be turned into the inner side of the mounting hole 22 by the knob 24, thereby completing the fixing of the position of the connecting rod 4, so that the height of the connecting rod 4 can be adjusted according to the number of second fixed cylinders 7 assembled, reducing the workload of the staff. When it is necessary to sort coarser materials, since the spring 21 is in a compressed state at this time, when the first threaded rod 19 is driven to turn away from the fixing hole 18 by the turning handle 20, the adjusting plate 17 loses its limit, and then the adjusting plate 17 can be driven to move upward by the reset of the spring 21. Subsequently, the adjusting plate 17 needs to be adjusted to a suitable position, and then the first threaded rod 19 is turned into the inner side of the fixing hole 18 by the turning handle 20, thereby completing the position limit of the adjusting plate 17 and increasing the overall height of the side guard plate 11, providing convenience for adjusting the height of the side guard plate 11, preventing material from overflowing or piling up, and improving the adaptability of the spiral chute.
