[0002] Phosphate rock refers to an ore containing phosphorus. Phosphorus is one of the essential nutrients for organisms and is widely used in agriculture, food processing, medicine and other fields. Phosphate rock usually includes mineral resources such as apatite and phosphogypsum, which are mainly used to produce fertilizers, livestock and poultry feed, food additives and other products. The mining and utilization of global phosphorus resources are of great significance to agricultural production and human life.

[0003] Phosphate ore is sorted using a sorting machine. However, existing ore sorting machines have a complex structure, are large in size, and require a large installation area, which is not conducive to later inspection and maintenance. At the same time, existing sorting machines rely solely on X-ray detection devices in conjunction with high-speed air valve blowing devices to separate ore from waste rock. The ore cannot be accurately positioned, which results in deviations when the high-speed air valve blowing device is blowing the ore, resulting in low ore sorting accuracy. Utility Model Content

[0006] The identification device comprises two 3D line array cameras, one of which is located at the bottom of the X-ray detection device and is obliquely mounted on the frame through a mounting plate; the other 3D line array camera is located on the left side of the X-ray detection device and is obliquely mounted on the frame through a positioning frame;

[0007] The collecting device comprises an ore collecting trough and a waste rock collecting trough which are installed on the top of the base through a supporting frame, and the waste rock collecting trough is located at the lower part between the high-speed air valve blowing device and the ore collecting trough.

[0008] Furthermore, a guide plate is provided at the bottom of the discharging end of the feeding belt, the X-ray detection device is installed at the bottom of the guide plate through a connecting frame, and the receiving device of the X-ray detection device is installed on a positioning frame.

[0010] Furthermore, the high-speed air valve blowing device is installed on the frame through a tripod.

[0011] Furthermore, an ore discharge belt and a waste rock discharge belt are respectively provided at the bottom of the ore collecting trough and the waste rock collecting trough.

[0012] Furthermore, an inclined baffle is provided at the top of the left end of the ore collecting trough, and a support rod is provided between the baffle and the left end surface of the ore collecting trough.
