Description

Technical Field

[0001] The utility model relates to the technical field of spiral sand washing machines, in particular to a spiral sand washing machine for mines. Background Art

[0002] Spiral sand washers are typically tilted, with a rotating shaft equipped with spiral blades driven by a motor through a reducer. Clean water is continuously fed into the spiral blades as they rotate, mixing the dirt and water in the sand and gravel in the sand washing trough. The water is then discharged from the machine's outlet. The sand and gravel are then gradually screened by the spiral mechanism and discharged from the top outlet, achieving a complete cleaning and screening effect. Spiral sand washers are suitable for washing, grading, and removing impurities in industries such as metallurgy, building materials, and hydropower. They are used for washing both fine and coarse-grained materials. They are particularly suitable for sand used in construction and road construction, offering low power consumption and high cleaning efficiency.

[0003] In application number: CN202121209309.3, a spiral sand washing machine for mines is disclosed. In this utility model, the sand body moves forward along the spiral blades in the sand washing trough and falls from the mine outlet, while the soil and dust are mixed into mud and filtered through the filter screen of the filter plate. Through the setting of the card strip and the through groove, the filter plate is slidably plugged into the sand washing trough. When the filter screen is damaged by the mud, the filter plate is directly pulled out of the through groove for repair, which facilitates the replacement of the filter screen and is convenient for disassembly and assembly.

[0004] However, the spiral blades of the spiral shaft of the device are easily damaged after long-term trial use. The spiral shaft of the current spiral sand washing machine is relatively complicated to install and difficult to disassemble. The spiral shaft cannot be quickly replaced, which affects the sand washing efficiency. In addition, sand and gravel are prone to cause blockage at the mine outlet, and the mine outlet needs to be manually unblocked. Therefore, a spiral sand washing machine for mines is proposed, which can quickly disassemble and replace the spiral shaft and automatically unblock the mine outlet to avoid sand and gravel blockage. Utility Model Content

[0009] By setting the conical head, when the ore outlet is blocked, the second motor can drive the conical head to rotate back and forth, so that the conical head can be inserted into the ore outlet multiple times, thereby providing a dredging function for the blocked ore outlet.

[0010] Specifically, two inserting blocks are provided opposite to each other, a spiral shaft is fixedly connected between the two inserting blocks, and a second bolt hole is opened inside the two inserting blocks.

[0011] Specifically, a first bolt hole is opened inside the two connecting heads, and the first bolt hole is matched with the second bolt hole.
