Description

Technical Field

[0001] The invention relates to the technical field of mineral mining equipment, and in particular to dual-channel intelligent visual ore dressing and conveying equipment with a self-cleaning function. Background Art

[0002] After the intelligent transformation, the mineral processing equipment can have the function of ore visual intelligent identification and mineral processing screening. After the ore is selected and identified, the sorting device is used to change the route of different types of ores so that the required ore falls into the collection frame to complete the ore sorting. Since the accuracy of the visual intelligent recognition of mineral processing equipment is very dependent on the quality of camera imaging, the ability to clearly capture the shape and original color of the ore on the transmission channel is the basis of visual recognition. For example, in the prior art: a device and method for ore particle size detection based on machine vision; CN202210230250.9, etc.

[0003] In order to solve the above problems, the technicians found that they should start from the following aspects: 1. There should be no obstructions or shadows on the illumination path of the industrial camera, and the light should be bright enough to illuminate the outline of the ore; 2. The background below the ore, that is, the transmission belt, should be made of a material with uniform color and texture, without large chromatic aberration damage and spots, so as to avoid misjudgment of the intelligent visual recognition system; 3. If the surface of the transmission belt is damaged, it should be able to be replaced quickly to avoid more misjudgment and misselected ore entering the next screening system, and to avoid affecting the mineral processing efficiency.

[0004] However, the existing visual intelligent identification beneficiation equipment has not been optimized for this, resulting in low accuracy of visual intelligent identification and failure to achieve the expected results. In addition, the process of replacing the conveyor belt is usually cumbersome, especially when the belt is too long, too wide, or has a large volume and weight. It is necessary to use large lifting equipment such as car cranes or cranes to assist in disassembly and assembly, which is time-consuming and labor-intensive. In addition, some belt conveyor equipment does not support the complete removal of the belt, and even requires the belt to be cut and removed; the same newly installed belt also needs to be reconnected at the break, which is a huge workload. Summary of the invention

[0005] The purpose of the present invention is to provide a dual-channel intelligent visual beneficiation conveying equipment with a self-cleaning function, which can effectively reduce the impact of dirt on the visual intelligent beneficiation system through the self-cleaning of the visual recognition system and the self-cleaning of the transmission belt. The frame of the present invention also has two synchronous transmission belts for parallel transmission, which can realize the production of large-throughput ore transmission and screening. The two belts can be disassembled and assembled separately, and the process of disassembling and assembling the transmission belts is simple and easy to operate, thereby improving the ore dressing efficiency of the equipment.

[0006] To achieve the above object, the technical solution of the present invention is as follows: A dual-channel intelligent visual mineral processing conveying equipment with a self-cleaning function, the conveyor belt on the transmission frame is divided into left and right sections to form two transmission channels, the shapes of the active roller and the driven roller at both ends of the transmission frame match the number of conveyor belts; the active roller is driven by a drive motor; the front end of the transmission frame is connected to a paver, and a sorting system is arranged at the rear end of the transmission frame, and the conveyor belt is connected below the material dividing frame of the sorting system; a visual recognition system is arranged above the transmission frame, and a belt cleaning mechanism is arranged below the transmission frame.

[0007] The paver is used to evenly discharge and evenly spread the piled ore that arrives in batches before transmission and sorting, so that the stones can be transmitted and sorted in an orderly and uniform manner, improving the accuracy and effect of subsequent sorting, reducing the risk of stone loss to the transmission device, and increasing the service life of the equipment. A vibration motor is set at the bottom of the paver's unloading platform, and a diversion baffle is set above the unloading platform to evenly divide the paved stones into two channels for the subsequent transmission mechanism.

[0008] The sorting system includes a closely arranged nozzle structure, which is installed at the end of the conveyor belt. The front of the nozzle is evenly distributed with horizontal injection ports, and the back of the nozzle is provided with several planes with different inclination directions. Several air inlets are arranged on each plane, and each air inlet is connected to an injection port channel. When each ore reaches the end of the conveyor belt, the nozzle corresponding to the position of this ore sprays the fluid ejected, and intervenes in the trajectory of the ore falling, so that it falls to the designated collection frame, so as to achieve the purpose of ore selection and screening. The solenoid valve is matched with each air inlet in the nozzle one by one. A material distribution funnel is set below the end of the conveyor belt, and a material distribution plate is set in the middle of the material distribution funnel to separate the funnel into two parts. The lower end of each part of the funnel is connected to different discharge belts. Different discharge parts of the funnel correspond to different discharge belts, and the ends of different discharge belts correspond to qualified ore collection frames or waste frames.

[0009] The structure of two parallel transmission belt channels can avoid the disadvantage of difficult disassembly and replacement brought about by the structure of a single wide transmission belt. When replacing the transmission belt, loosen the tensioning shaft and pull the belt out horizontally from the outside. The weight of a single transmission belt is limited and can be completed manually without lifting equipment, thereby improving the efficiency of equipment maintenance.

[0010] A tensioning mechanism is respectively arranged below the middle part of each conveyor belt, and the tensioning mechanism comprises two left and right rollers, a belt tensioning shaft is arranged between the two rollers, the rollers are mounted on the frame through roller mounting plates, and the belt tensioning shaft is mounted on the frame through the tensioning shaft mounting plates.

[0011] The tensioning mechanism of each belt can be operated and functioned independently. When the belt tensioning shaft is supported, the belt is tensioned; when the belt tensioning shaft is retracted, the belt is loosened for replacement. The design of the independent tensioning mechanism can realize the disassembly and replacement of each belt separately.

[0012] The tensioning shaft mounting plate is provided with a long groove, the opening direction of the long groove is opposite to the movement direction of the conveyor belt, the lower end of the tensioning shaft mounting plate is provided with an opening, the opening direction is opposite to the movement direction of the conveyor belt, a tensioning screw is arranged at the opening, the threaded portion of the tensioning screw is threadedly connected with the shaft extensions at both ends of the belt tensioning shaft, and the shaft extensions at both ends of the belt tensioning shaft are horizontally limited by the long groove; When the tensioning force needs to be increased, the tensioning screw is turned, and the screw pulls the belt tensioning shaft downward to generate greater tensioning force. When the conveyor belt needs to be disassembled, the tensioning screw is turned, and the screw moves the belt tensioning shaft upward. After the conveyor belt is loosened, the roller is removed from the roller mounting plate, and the conveyor belt can be directly disengaged from the side.

[0013] An open L-shaped opening groove is arranged at the lower end of the roller mounting plate, and the shaft extension of the roller is clamped in the L-shaped opening groove. The L-shaped opening groove facilitates the quick installation and removal of the roller, and can be directly hung without bolt fastening.

[0014] The lower middle part of the column of the transmission frame is connected to the lower support plane composed of the lower cross beam and the lower longitudinal beam. The lower support plane is fixedly connected to the bottom end of the herringbone support. The top of the herringbone support supports the bottom of the conveyor belt frame. The conveyor belt frame is composed of the upper longitudinal beam and the upper cross beam. The driving shaft and the driven shaft are respectively installed at both ends of the conveyor belt frame. The support points of the upper support plane are concentrated at the top of the herringbone support. There is free space on both sides. The conveyor belt can be freely moved in and out and disassembled from both sides of the upper support plane to achieve rapid installation and disassembly of the belt.

[0015] The visual recognition system support frame is equipped with an industrial camera, a glass sheet is arranged below the industrial camera, and the lower end surface of the glass sheet is cleaned by a reciprocating rubber scraper and / or an air nozzle; The glass sheet is a highly transparent non-reflective glass sheet, which will not affect the imaging effect of the industrial camera; the rubber scraper and / or the air nozzle can be installed one by one, or both at the same time. After the lower surface of the glass sheet has been working for a period of time, the rubber scraper and / or the air nozzle will perform a reciprocating motion at a fixed time to scrape or blow away the dirt attached to the lower surface of the glass sheet; when the rubber scraper and the air nozzle are installed at the same time, the cleaning effect is better. The air nozzle connected to the high-pressure air source through a pipeline is set in the position before the rubber scraper. The air nozzle first blows the glass sheet once. After most of the dirt is blown away, the rubber sheet will scrape off the remaining dirt. This can reduce the scraping load of the rubber sheet and prevent the dirt from accumulating too much on the rubber sheet, affecting the cleaning effect. The air nozzle can be a single-point nozzle or a parallel multi-nozzle nozzle arrangement, which is connected to the high-pressure air supply pipeline through a solenoid valve; a speed regulating valve can also be installed on the blowing nozzle to adjust the amount of air jet.

[0016] The rubber scraper and / or air nozzle is mounted on a slider and connected to a stepper motor through a screw rail and a screw. A stepper motor is also called a pulse motor, which is an electric motor that converts an electrical pulse signal into a corresponding angular displacement or linear displacement. Each time a pulse signal is input, the rotor rotates an angle or moves forward one step. The angular displacement or linear displacement output is proportional to the number of input pulses, and the rotation speed is proportional to the pulse frequency. The stepper motor can accurately locate the travel distance of the rubber scraper and / or air nozzle to prevent deviation in the moving position.

[0017] The rubber scraper and / or air nozzle are connected to the piston rod of cylinder A; the three-axis cylinder can be used as an alternative to the stepper motor, and the forward and backward movement of the cylinder piston rod is used as the power of the rubber scraper and / or the air nozzle. The advantage of the cylinder is that the workshop's own high-pressure air can be used as a power source; the cylinder is equipped with a speed regulating valve to adjust the speed of the piston movement; the cylinder is provided with a cylinder sensor to measure the position of the feedback piston rod.

[0018] Position sensors are respectively arranged at both ends of the screw slide rail; a sensing sheet is arranged on the slider, the slider is connected to a rubber scraper and / or an air nozzle, and can slide freely on the slide rail, and the power for the slider to move forward or backward is provided by the rotation of the screw rod; when the end position sensor senses the slider, a signal is sent to the industrial computer, and the stepper motor can be controlled to reverse; when the initial end position sensor senses the slider, the single chip microcomputer controls the stepper motor to stop.

[0019] The industrial camera is provided with a camera housing. The camera housing is used to protect the industrial camera and prevent the external environment from causing damage and interference to the camera. The camera housing is fixedly connected to the crossbeam.

[0020] A plurality of adjusting screws are fixed on the crossbeam on the visual recognition system support frame, and a movable plate is passed through the adjusting screw and positioned with a nut, and the movable plate is fixedly connected to the industrial camera. The movable plate is on the screw and moves by adjusting the position of the upper and lower nuts to meet the focal length requirements of the industrial camera.

[0021] The conveyor belt cleaning mechanism comprises a cylinder B, and a brush strip is installed at the front end of the piston rod of the cylinder B. When the piston rod is extended to the right position, the brush strip can scrape and contact the conveyor belt for cleaning; After the conveyor belt runs for a period of time, the PLC controls the cylinder solenoid valve, the piston rod extends and the brush bar contacts and scrapes the circulating conveyor belt; at this time, the position sensor on the cylinder head is energized, and the system displays that the cleaning work is in progress. After a period of cleaning, the PLC controls the cylinder solenoid valve, the piston rod retracts the brush bar and separates it from the conveyor belt, completing a cycle of cleaning operations. At this time, the position sensor on the tail of the cylinder is energized, and the system displays that the cleaning is not in progress.

[0022] The cylinder can be replaced by an electric push rod. The driving motor of the electric push rod is a stepper motor or a servo motor. When the brush wears out or the belt cleaning effect is poor, the feed distance of the electric push rod can be controlled to increase to improve the above situation.

[0023] The cylinder B is mounted on the frame through a belt cleaning mechanism support frame, and a plurality of air nozzles are mounted on the belt cleaning mechanism support frame to form a horizontal array, and the outlet of the air nozzle corresponds to the position of the brush bar when the piston rod of the cylinder B is retracted. Each time the system detects that the cleaning is completed and is on standby, the solenoid valve connected to the air blowing nozzle is energized, and the air blowing nozzle array blows air to the brush to blow off the sand, dust and debris in the brush bar.

[0024] A plurality of air nozzles are also installed at the end of the piston rod of the cylinder B to form a horizontal array, and the outlet of the air nozzle corresponds to the middle of the brush bar. The air nozzle array is fed simultaneously with the brush bar. When the system detects that the brush bar is extended to the right position, the air nozzle solenoid valve is opened at the same time, and the air nozzle blows the brush bar. Sweeping and blowing cleaning are carried out simultaneously to blow away the debris, dust and sand in the brush bar; when the system detects that the brush bar is retracted to the right position, the air nozzle solenoid valve is closed and the blowing stops.

[0025] The rear end of the piston rod of the cylinder B is a screw rod, which is sleeved with a limit sleeve and a threaded adjustment nut, and the limit sleeve is positioned by the adjustment nut. After the brush has worked for a certain period of time, if the belt cleaning degree does not meet the requirements, the adjustment nut at the tail of the cylinder piston can be manually adjusted to increase the stroke of the piston so that it can just contact the belt. After multiple adjustments, the brush can be replaced when the stroke is exhausted. Advantages of the invention

[0026] 1. The present invention has two synchronous conveying belts for parallel transmission, which can realize the production of large-throughput ore transmission and screening, and the two belts can be disassembled and assembled separately. While realizing large-throughput transmission, it will not increase the difficulty of belt replacement, and there is no need to use lifting equipment for belt replacement.

[0027] 2. The free space for installing and removing the belt is reserved on the side of the equipment of the present invention, and the belt can be installed and removed from the side, which can avoid the tedious operation of cutting and removing the belt, and the operation is convenient.

[0028] 3. The visual recognition system of the present invention performs intermittent self-cleaning of the glass plate through a rubber scraper and an air nozzle, thereby ensuring the smooth operation of the visual recognition beneficiation device, improving the recognition effect of the visual recognition device, reducing the maintenance frequency of the equipment, and improving the production efficiency of the equipment.

[0029] 4. The belt cleaning mechanism of the present invention uses a brush bar that can be automatically extended and retracted by a cylinder to scrape and clean the conveyor belt in circulation, which greatly increases the service life of the conveyor belt, reduces production losses, and improves production efficiency; and at the same time, a follow-up or non-follow-up jet array is provided to automatically blow the brush bar to prevent the accumulation of debris, dust and sand and gravel from affecting the cleaning effect.

[0030] 5. Each self-cleaning mechanism in the present invention is automatically controlled by PLC, without manual participation, with high degree of automation and convenient maintenance. BRIEF DESCRIPTION OF THE DRAWINGS
