Background

At present, the ore sorting machine can sort ores and reject unqualified ores.

The ore sorting machine can greatly improve the productivity while ensuring the quality of the ore, and solves the problem of low efficiency of traditional manual ore sorting. However, in the use process of the existing ore vibration separator, ores are conveyed to a designated position through a conveyor belt, but the conveyor belt device still occupies an operation area when the equipment does not work and cannot be conveniently folded, so that the occupied area of the equipment is large, and the equipment is inconvenient to transport; the ores can be in an overlapped and shielded state before being sorted, so that the ore identification is not facilitated, the pipeline sorting device can cause the material blocking phenomenon due to different sizes of the ores, the efficiency of the manipulator sorting device is low, and the requirement on the grabbing precision is high; the electromagnetic force of the vibrating disc sequencing device is often fixed, but because the specifications of mined ores are random, the electromagnetic force with fixed magnitude cannot generate the inertia force required by the movement of the ores with different specifications; when the sorting quantity is large, unqualified ores are not removed due to the limitation of the response speed of the push-pull type electromagnet removing device, so that the phenomenon of omission is caused.

Through the above analysis, the problems and defects of the prior art are as follows:

(1) the ore passes through the conveyer belt and carries the assigned position, but conveyor means still can occupy the operating area when equipment is out of work, can not convenient packing up, causes equipment area big, the transportation of inconvenient equipment.

(2) The ore can present the state of overlapping and sheltering from before the sequencing, is unfavorable for the discernment of ore, and the pipeline sequencing device can cause the card material phenomenon because of the variation in size of ore, and manipulator sequencing device is inefficient, and is required the height to snatching the precision.

(3) The electromagnetic force of the vibrating disk sequencing device is usually fixed, but because the ore specifications of mining are random, the electromagnetic force with fixed magnitude cannot generate the inertia force suitable for the movement of the ores with different specifications.

(4) When the sorting quantity is large, unqualified ores are not removed due to the limitation of the response speed of the push-pull type electromagnet removing device, so that the phenomenon of omission is caused.

The difficulty in solving the above problems and defects is: traditional ore sorting machine is unfavorable for discerning owing to sheltering from each other of ore when selecting separately, if want discernment accuracy and the work efficiency that improves the sorter, then can lead to the structure of complete machine complicated, makes complete machine size greatly increased, is unfavorable for the transportation of equipment, and complicated mechanical structure is not convenient for equip the maintenance and repair to the energy consumption of complete machine can greatly increased.

The movement of the push rod 504 is realized by driving the crank 502 to rotate, unqualified ores are pushed down from the linear slideway, and the removing devices are respectively and fixedly arranged on one side of the linear slideway.

The linear feeding devices are respectively and fixedly arranged at the discharge holes of the spiral tracks 209 and used for transporting ores output by the spiral tracks 209 backwards in a linear motion mode, each linear feeding device consists of a linear vibrator and a linear track, and the linear vibrator is a mature product and the structure and the principle of the linear vibrator are not repeated herein.

The ore output device is composed of two conveyor belt mechanisms, the two conveyor belts are fixedly arranged at the bottom of the whole machine one above the other respectively, qualified ores and unqualified ores rejected by the rejection device can fall to the two conveyor belts through slideways respectively, the ores are conveyed to the next production link, and the conveyor belt mechanisms are a mature technology and are not repeated.

The working principle of the invention is as follows: the ore input device is connected through the pivot in carrying the branch charging tray with the ore through gear motor driven PVC area, and the ore input device divide into the three-section, pulls out it from the box is inside during operation, and the non-operating time can push into the box top. After entering the material distribution disc, the ores slide into the corresponding sorting devices through the four material distribution slideways. The sequencing device is composed of four vibrating disks with adjustable electromagnetic force, the vibrating disks are respectively positioned below the material distribution slide ways, ores are gradually arranged into a straight line through the vibration of the vibrating disks and are output outwards through a spiral track, the electromagnetic force is realized by adjusting the height of an electromagnet, the rotation of the horizontal axis is converted into the rotation of the vertical axis by using a worm gear, the slide block is moved up and down through the rotation of the vertical axis, the height adjustment is realized, and meanwhile, the fixation of the position of the slide block is realized by using the self-locking of the worm gear and the thread. The ores are arranged into a straight line through the sorting device and then enter the linear feeding device, the linear feeding device further conveys the ores forwards through the linear vibrator, unqualified ores are removed through signal identification during conveying, the removing function is realized through a centering crank-slider mechanism driven by a servo motor, the servo motor drives a crank to rotate, rotation is changed into reciprocating linear motion of a push rod, and unqualified ores are removed through the push rod. Rejected unqualified ores fall into a conveyor belt below the box body, and qualified ores fall into the other conveyor belt through the linear feeding device and are then output to the outer side of the box body.

According to the technical scheme of the invention, modeling and detailed structure design are carried out through CAD software, the model selection design analysis is carried out on key devices and structures, the design is determined to meet the requirement of strength design through finite element analysis, and the strength of key parts is ensured. The size of the whole machine is less than 5000mm multiplied by 3000mm multiplied by 2500mm, parts which are key to bear heavy load are theoretically checked and meet the safety requirement, the ore sorting quantity is over 100t/h through detailed design and simulation analysis, the ore with the size of 20 mm-75 mm can be sorted, the sorting speed is high, the response time is about 1ms, and the energy consumption and the cost of the whole machine are low through the model selection design.
