[0002] A spiral separator is a device widely used in the coal preparation industry, mainly used for sorting materials. Its working principle is mainly to use the spiral movement of water flow to sort materials according to density, and is suitable for sorting coarse coal slime of 3 - 0.15 mm grade. Due to its advantages such as simple structure, convenient operation and maintenance, low energy consumption, and high efficiency, the spiral separator is mainly used in the sorting and recovery process of coarse coal slime in coal washing and processing.

[0003] The working principle of the spiral separator is to rely on the centrifugal force generated by the rotation of the spiral shaft and the gravity of the material. Materials with different densities move along different trajectories in the spiral trough, so as to achieve separation. Specifically, the material continuously and evenly enters the sorting trough of the spiral separator from the feeding device. Under the rotation of the spiral shaft, the material is subjected to centrifugal force. Materials with a larger density tend to the inner side of the spiral shaft, while materials with a smaller density tend to the outer side. Finally, materials with different densities are separated through different discharging devices.

[0004] Regarding the existing related technologies, the inventor believes that there are the following defects: When feeding the spiral separator in the existing technology, the material is generally transported to the feeding port of the spiral separator through a conveyor belt for sorting. However, since the conveyed material is not preliminarily screened, large pieces of material will cause blockage after entering the spiral separator, thereby affecting the production efficiency. Summary of the Utility Model

The spiral separator body is arranged at the bottom of the guide plates. One end of the top of the spiral separator body is fixedly connected with a feeding port. One end of the guide plates is processed with a discharging chute. The feeding port is located at the bottom of the discharging chute. The other end of the bottom of the spiral separator body is fixedly connected with a discharging outlet.

[0007] Preferably, a first motor is arranged on the outer side of the fixing plates. One end of the first motor drives the conveyor belt to transmit through a rotating shaft.

[0008] Preferably, a second motor is arranged on the outer side of the fixing plates. One end of the second motor is fixedly connected with a first gear. One end of the first gear is fixedly connected with the roller.

[0009] Preferably, a belt is meshed and connected to the outside of the first gear. A plurality of second gears are meshed and connected inside the belt. One end of the second gears is fixedly connected with one end of the roller.

When the material reaches the top of the roller 7 after passing through the conveyor belt 6, the second motor 13 works to drive a plurality of rollers 7 to rotate. The material will be conveyed on the top of the rollers 7, so that small pieces of the material fall into the inside of the guide plate 8 through the gap between the two rollers 7 and reach the inside of the spiral separator body 2 through the feeding chute 12 at the bottom of the guide plate 8, thus completing the preliminary screening of the material and preventing large pieces of material from entering the inside of the spiral separator body 2 and causing blockage;

[0023] In some examples, a waste residue box 10 is provided at the bottom of one end of the fixing plate 4, and the waste residue box 10 is located at the bottom of the baffle 9;

[0024] Secondly, since one end of the fixing plate 4 close to the spiral separator body 2 is inclined downward, under the influence of the conveyance of a plurality of rollers 7 and its own gravity, large pieces of material will move to one end of the fixing plate 4 and enter the inside of the waste residue box 10 for collection;

[0025] Furthermore, a first motor 5 is provided on the outside of the fixing plate 4. One end of the first motor 5 drives the conveyor belt 6 to rotate through the rotating shaft. By starting the first motor 5, the first motor 5 drives the conveyor belt 6 to work through the rotating shaft, thereby enabling the conveyor belt 6 to convey the material to the top of the roller 7;

[0026] Furthermore, a second motor 13 is provided on the outside of the fixing plate 4.
