Description

Technical Field

[0001] The utility model relates to the technical field of ore sorting equipment, in particular to an intelligent device for ore sorting and screening. Background Art

[0002] Ore refers to a mineral aggregate from which useful components can be extracted, or which has certain properties that can be utilized. It can be divided into metal minerals and non-metallic minerals. The unit content of useful components (elements or minerals) in an ore is called the ore grade. Precious metal ores such as gold and platinum are expressed in grams per ton, and other ores are often expressed in percentages. After being processed step by step such as crushing and grinding, the ore can be used in engineering fields such as metal mines, metallurgical industry, chemical industry, construction industry, railway (highway) construction units, cement industry, and sand and gravel industry.

[0003] At present, ore sorting and screening are mostly carried out by vibrating screens, but the screening size is limited by the mesh size of the screen, and the screening subdivision is limited. In the subsequent sorting and processing of the ore, the ore needs to be further screened manually, which consumes a lot of time and manpower. At the same time, during the screening process, the screen is often blocked by the ore and is prone to blockage, affecting the screening efficiency of the screen. Therefore, as long as the machine is started, staff are required to be on duty to deal with problems in a timely manner. Utility Model Content

[0028] A screening box 8 is fixedly connected to the top of one end of the sorting platform 1 away from the unloading rack 5. An opening is provided on the top of the sorting platform 1 and a limit frame 14 is fixedly connected to the edge of the opening. The opening is connected to the bottom of the screening box 8. The limit frame 14 extends into the screening box 8 and is fixedly connected to the inner wall of the screening box 8, so that the ores screened out of the screening box 8 can fall into several sorting boxes 2 in the sorting platform 1 respectively, which is convenient for the staff to classify.

[0029] Two conveyor belts 9 are arranged inside the screening box 8. The conveyor belt 9 includes a front sprocket 901 and a rear sprocket 902, and the driving shafts of two synchronous drive motors 10 are fixedly connected to the front sprocket 901 and the rear sprocket 902 respectively. The outer walls of the front sprocket 901 and the rear sprocket 902 are meshed and connected with a steel chain 903. The inner wall bearing of the screening box 8 is connected with a support wheel 904, and the support wheel 904 fits with the inner top of the steel chain 903. The distance between the two steel chains 903 increases from high to low. The two conveyor belts 9 are arranged at a certain angle, that is, as the conveyor belt 9 is transported from high to low, the distance between the two steel chains 903 becomes larger and larger, so that small-sized ores fall first and larger-sized ores fall last for sorting.

[0030] Synchronous drive motors 10 corresponding to the two conveyor belts 9 are fixedly connected to both sides of the outer wall of the screening box 8, and guide plates 11 are fixedly connected to both sides of the inner wall of the screening box 8, wherein the guide plate 11 is located at the top of the conveyor belt 9, the guide plate 11 is parallel to the top of the conveyor belt 9 and the bottom of the guide plate 11 is located on the center line of the top of the conveyor belt 9, so that all the ore is in the center position between the two conveyor belts 9, and can fall quickly when it reaches the size for sorting.

When the size is smaller than the size between the two conveyor belts 9, the ores can fall into the sorting box 2.

[0036] During this period, the screening situation in the screening box 8 can be clearly observed through the observation window 12, and the wide-angle camera 13 can be used to monitor the screening situation in the screening box 8 in real time, and the video signal can be connected to the staff's external mobile phone, computer and other wireless network terminals through the wireless network, so that the staff can control multiple groups of screening machines at the same time without having to check them on site one by one, which brings convenience to the staff's work. Once a problem is found in the equipment, the maintenance personnel can be notified in time for maintenance.

[0037] The ore that finally enters the sorting box 2 is conveyed along the conveyor belt 4 and discharged from the bottom outlet of the unloading rack 5 for collection.
