Description

Technical Field

[0001] The invention relates to the technical field of ore screening, and in particular to an intelligent three-axis elliptical vibrating screen. Background Art

[0002] Vibration screening equipment is one of the most critical mechanical equipment in the ore mining and processing industry. It is an indispensable and important component of the entire production line. It uses the vibration on the porous working surface (screen) to separate particles of different sizes, thereby realizing ore screening. Equipment designed specifically for screening materials in quarries can also be used for product classification in coal preparation, mineral processing, building materials, electricity and chemical industries. With the rapid development of modern industry, the requirements for material screening are increasing. Traditional single-axis and two-axis vibrating screens gradually reveal their limitations when handling some complex materials and high-output requirements. For example, in the mining industry, with the increase in ore mining and the diversification of ore types, a device that can more efficiently separate ores of different particle sizes, with a large processing capacity and high screening accuracy is needed. The construction industry is also increasingly stringent in its requirements for the quality and particle size distribution of building materials such as sand and gravel to meet the needs of high-quality construction projects.

[0003] After searching, the invention patent with Chinese patent number CN118768207A discloses an intelligent three-axis elliptical vibrating screen. It is proposed that the vibrating screen body includes a base and a vibrating screen body, the vibrating screen body is located above the base, two U-shaped frames are fixedly installed on both sides of the vibrating screen body, a plurality of connecting components are arranged on the top of the base, the top of the connecting component is fixedly connected with the U-shaped frame, a plurality of elastic components are arranged on the top of the base, the elastic components are located in the middle of the connecting components, the bottoms of the plurality of U-shaped frames are fixedly installed with T-shaped rods, the insides of the strip grooves on both sides of the base are provided with shock absorbing components, and the shock absorbing components are located on the inner bottom wall of the base. Through the first detection unit, the second detection unit, the state detection system and the controller, the operating state of the vibrating screen body can be monitored in real time, and the abnormal state can be analyzed and warned in time, and fault diagnosis can be given. At the same time, the load condition can be judged according to the operating state, and the operating state can be adjusted by adjusting the output of the transmission system to reduce the energy consumption per unit of finished product.

[0004] However, in actual use of the above device, when using a three-axis vibrating vibrating screen to screen and sort the ore, if there is a larger ore outside the screen, it will cause the smaller ores above the larger ore to form a stack, and the smaller ore on the upper part will be difficult to pass through the screening quickly, resulting in a significant reduction in screening efficiency and low work efficiency. Therefore, an intelligent three-axis elliptical vibrating screen is proposed. Summary of the invention

[0005] The purpose of the present invention is to solve the problem in the prior art that when a three-axis vibrating vibrating screen is used to screen and sort ores, if larger ores are outside the screen, smaller ores above the larger ores will be stacked, and the smaller ores on the top will be difficult to pass through the screening quickly, resulting in a significant reduction in screening efficiency and low work efficiency. An intelligent three-axis elliptical vibrating screen is proposed to solve the problem.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0011] A three-axis vibration mechanism is arranged outside the substrate, and the three-axis vibration mechanism includes a second motor arranged outside the substrate, a main transmission shaft is arranged at the output end of the second motor, a first gear is fixedly connected to a side of the main transmission shaft close to the second motor, a second gear is meshedly connected to a side of the first gear, and a first transmission shaft is fixedly connected to a side of the second gear, and the second gear is operated so that the main transmission shaft and the first transmission shaft are changed from a stationary state to a rotating state.

[0012] A side of the first gear away from the second gear is transmission-connected with a second transmission shaft, and the second transmission shaft is driven to rotate by the same set of second gears.

[0013] A transverse plate is fixedly connected to one side of the base plate close to the screen plate. The transverse plate is fixedly connected to the screen plate, rotatably connected to the main transmission shaft, and rotatably connected to the first transmission shaft.
