Summary of the Invention

[0005] In order to overcome the disadvantages that although the above patent can make the mineral materials fall evenly downward and be screened by the vibrating screen, since soil or other impurities are attached to the mineral materials, the volume of the mineral materials increases, affecting the subsequent screening by the vibrating screen and the screening effect, the present invention provides a feeding device for a mineral separation vibrating screen with a mineral material pretreatment function, which can remove the impurities attached to the mineral materials to prevent the impurities from attaching to the mineral materials and affecting the subsequent screening, and improve the screening effect.

[0006] The present invention is achieved through the following technical means: A ore separation vibrating screen feeding device with ore material pretreatment function, comprising a housing and a feed hopper fixedly connected to the housing. The feed hopper is communicated with the inside of the housing. A guide plate which is inclined is fixedly connected to the inner side of the housing to guide the ore material. Vibration plates are slidably penetrated through both the left and right sides of the housing. A receiving plate is fixedly connected to the vibration plate. Connecting springs are symmetrically connected between the vibration plate and the housing. A vibration motor is installed on the vibration plate. It further includes a wire conduit, a pull wire, a movable plate, a contact rod, a trigger plate, a discharge frame, a jet pipe, a driving component and a material distribution component. The material distribution component is installed on the feed hopper and is used to drive the ore material to enter the housing separately for pretreatment. Wire conduits are symmetrically and fixedly connected to both the left and right sides of the housing. Movable plates are slidably connected to the outer left and right side surfaces of the housing. A pull wire is connected to the movable plate. The tail end of the pull wire passes through the wire conduit and is fixedly connected to the vibration plate. Contact rods are fixedly connected to both the front and rear side surfaces of the movable plate. Trigger plates are symmetrically and fixedly connected to the outer left and right side surfaces of the housing. The middle part of the trigger plate is an inclined surface. A jet pipe is communicated with the front side of the housing. A discharge frame is communicated with the rear side of the housing. A driving component is arranged on the housing and is used to drive the movable plate to move downward. The movable plate drives the vibration plate to move towards the direction of the wire conduit through the pull wire. When the driving component operates and contacts the trigger plate, the driving component loses the limit on the movable plate. Under the action of the connecting spring, the vibration plate throws the ore material through the receiving plate. Subsequently, the jet pipe sprays air at high speed to blow the impurities in the ore material into the discharge frame for discharge, so as to complete the pretreatment of the ore material.

[0007] Further explanation, a filter screen is arranged inside the discharge frame to prevent the ore material from entering the discharge frame.

[0008] Further explanation, the driving component includes electric push rods fixedly connected to both the left and right sides of the housing. The end parts of the telescopic rods of the electric push rods are symmetrically and fixedly connected with connecting plates. The end parts of the connecting plates are rotatably connected with hooks. The top of the hook is an inclined surface. The hook contacts the contact rod to drive the contact rod to move. A torsion spring is connected between the hook and the connecting plate. A round rod corresponding to the trigger plate is fixedly connected to the bottom end of the hook.

[0009] Further explanation, the material distribution component includes a guide frame fixedly connected to the inner side of the feed hopper. A slotted cylinder is rotatably connected to the inner side of the guide frame. A groove wheel located outside the feed hopper is fixedly connected to the shaft part of the slotted cylinder. A dryer is fixedly penetrated through the feed hopper. A mounting plate is fixedly connected to the outer side surface of the feed hopper. A servo motor is installed on the mounting plate. A disc is fixedly sleeved on the output shaft of the servo motor. A driving rod is fixedly connected to the eccentric position of the disc to drive the groove wheel to rotate. An opening and closing component is arranged between the feed hopper and the servo motor and is used to control the dropping of the ore material.

[0010] Further description: The opening and closing assembly includes opening and closing plates symmetrically and rotatably connected between the front and rear sides of the feeding hopper to control the dropping of ore. A one-hole plate located outside the feeding hopper is fixedly sleeved on the shaft part of the opening and closing plate. A return plate is slidably connected to the outer side of the feeding hopper. Return springs are symmetrically connected between the return plate and the feeding hopper. L-shaped rods are symmetrically and fixedly connected to the return plate. The L-shaped rods are slidably connected to the inner side of the one-hole plate to drive the one-hole plate to swing. A U-shaped rod is fixedly connected to the return plate. A cam corresponding to the U-shaped rod is fixedly sleeved on the output shaft of the servo motor to drive the U-shaped rod to move.

[0011] Further description: The ore selection vibrating screen feeding device with the function of ore pretreatment further includes a material blocking assembly. The material blocking assembly includes a material blocking plate rotatably connected to the end of the receiving plate to block the ore on the receiving plate. Elastic telescopic rods are symmetrically and rotatably connected between the material blocking plate and the vibrating plate. Blocking rods are symmetrically and fixedly connected to the front and rear sides of the housing. The ends of the blocking rods contact the material blocking plate to drive the material blocking plate to swing.

[0012] Further description: The elastic telescopic rod is composed of a sleeve, a rod and a spring. The sleeve is rotatably connected to the material blocking plate, the rod is slidably connected in the sleeve, the end of the rod is rotatably connected to the vibrating plate, and the spring is connected between the end of the rod and the inner side of the sleeve.

[0013] Further description: The ore selection vibrating screen feeding device with the function of ore pretreatment further includes rubber rollers evenly and spacedly fixedly connected to the inner side of the housing. The rubber rollers contact the vibrating plate to buffer the vibrating plate.

[0014] The remarkable progress of the present invention lies in: 1. Whenever the ore drops onto the receiving plate, the vibration motor is started, so that the vibrating plate vibrates the ore through the receiving plate to separate the impurities from the ore. Then, an external air pump is started to discharge air into the spray pipe, and the spray pipe sprays the air at high speed. When the ore is thrown out, the air sprayed at high speed can blow the impurities in the ore into the discharge frame for discharge, so as to prevent the impurities from adhering to the ore and affecting the subsequent screening, thereby improving the screening effect.

[0015] 2. Under the action of the opening and closing plate and the grooved cylinder, whenever the servo motor is started, the opening and closing plate opens to allow an appropriate amount of ore to enter the grooved cylinder. Then, the grooved cylinder rotates in reverse to drive the ore to rotate in reverse and correspond to the dryer for drying. The dried ore is driven by the grooved cylinder to drop below and fall into the housing to remove impurities and complete the pretreatment. The ore can be intermittently dropped to remove impurities and complete the pretreatment, so as to prevent a large amount of ore from dropping and accumulating together and affecting the pretreatment.

[0016] 3. Under the action of the material blocking plate, whenever the ore drops onto the receiving plate, the material blocking plate can block the ore on the receiving plate, preventing the ore from dropping from the receiving plate before vibration, thus ensuring that the ore can be completely vibrated to complete the separation of impurities.

[0030] Embodiment: A ore dressing vibrating screen feeding device with ore material pretreatment function. Please refer to Figures 1-8 As shown in the figure, it includes a housing 1 and a feed hopper 2 fixedly connected to the middle of the top of the housing 1. The feed hopper 2 is communicated with the inside of the housing 1. A guide plate 3 is fixedly connected to the right side of the inner top of the housing 1. The guide plate 3 is inclined and can guide the ore material. Vibration plates 4 are slidably penetrated through the left and right sides of the housing 1. Two receiving plates 6 are fixedly connected to the side of the left and right vibration plates 4 close to each other. The left and right receiving plates 6 are arranged staggeredly. Connection springs 5 are symmetrically connected up and down between the sides of the left and right vibration plates 4 away from each other and the left and right inner side surfaces of the housing 1.

It also includes a wire conduit 8, a pull wire 81, a movable plate 82, a contact rod 83, a trigger plate 84, a discharge frame 71, a jet pipe 72, a driving component and a material distribution component. The material distribution component is installed on the feed hopper 2. When the material distribution component operates, it can drive the ore material to be separated and enter the housing 1 for pretreatment. Wire conduits 8 are symmetrically fixedly connected up and down on the left and right sides of the housing 1. Movable plates 82 are vertically slidably connected to the middle parts of the left and right outer side surfaces of the housing 1. Pull wires 81 are connected to the upper and lower sides of the movable plate 82. The tails of the upper and lower pull wires 81 respectively pass through the upper and lower wire conduits 8 and are fixedly connected to the vibration plates 4. Contact rods 83 are fixedly connected to the middle parts of the front and rear side surfaces of the movable plate 82.

A jet pipe 72 is communicated with the front side of the housing 1. A discharge frame 71 is communicated with the rear side of the housing 1. A filter screen is arranged inside the discharge frame 71 to prevent ore material from entering the discharge frame 71. A driving component is arranged on the housing 1. The driving component is used to drive the movable plate 82 to move downward. The movable plate 82 drives the vibration plate 4 to move towards the direction of the wire conduit 8 through the pull wire 81. When the driving component operates and contacts the trigger plate 84, the driving component loses the limit on the movable plate 82. Under the action of the connection spring 5, the vibration plate 4 throws the ore material through the receiving plate 6. Then the jet pipe 72 sprays air at high speed to blow the impurities in the ore material into the discharge frame 71 for discharge, so as to complete the pretreatment of the ore material.

[0031] Please refer to Figure 3 and Figure 4As shown in the figure, the driving assembly includes an electric push rod 9, a connecting plate 91, a hook 92, a round rod 93 and a torsion spring 94. Electric push rods 9 are fixedly connected to the upper parts of the left and right side surfaces outside the housing 1. Connecting plates 91 are fixedly connected to the front and rear ends of the telescopic rod ends of the left and right electric push rods 9. A hook 92 is rotatably connected to the end of the connecting plate 91 away from the housing 1. The top of the hook 92 is a slope, and the hook 92 contacts the contact rod 83. When the hook 92 moves downward, the hook 92 can drive the contact rod 83 to move downward. A torsion spring 94 is connected between the hook 92 and the connecting plate 91. A round rod 93 is fixedly connected to the bottom end of the hook 92, and the round rod 93 corresponds to the trigger plate 84.

[0032] Please refer to Figures 6-8As shown in the figure, the material distribution component includes a material guiding frame 10, a grooved cylinder 101, a dryer 102, a grooved wheel 103, a mounting plate 104, a servo motor 105, a disc 106, a driving rod 107 and an opening and closing component. A material guiding frame 10 is fixedly connected to the lower inner side of the feed hopper 2. The lower inner side of the material guiding frame 10 is rotatably connected to a grooved cylinder 101. There are four grooves on the grooved cylinder 101. The front end of the shaft of the grooved cylinder 101 is fixedly connected to a grooved wheel 103. The grooved wheel 103 is located outside the feed hopper 2. A dryer 102 is fixedly inserted through the lower left part of the feed hopper 2. The lower front side of the outer side of the feed hopper 2 is fixedly connected to a mounting plate 104. A servo motor 105 is installed in the middle of the mounting plate 104. A disc 106 is fixedly sleeved on the output shaft of the servo motor 105. A driving rod 107 is fixedly connected to the eccentric position of the disc 106. When the driving rod 107 rotates and contacts the groove of the grooved wheel 103, the driving rod 107 can drive the grooved wheel 103 to rotate by 90 degrees. An opening and closing component is arranged between the feed hopper 2 and the servo motor 105. When the opening and closing component operates, the opening and closing component can control the falling of the ore. The opening and closing component includes an opening and closing plate 108, a slotted plate 109, a return plate 1010, a return spring 1011, an L-shaped rod 1012, a cam 1013 and a U-shaped rod 1014. The opening and closing plates 108 are symmetrically rotatably connected to the left and right between the lower parts of the front and rear sides of the feed hopper 2. The opening and closing plates 108 can control the falling of the ore. The front ends of the shafts of the left and right opening and closing plates 108 are fixedly sleeved with a slotted plate 109. The slotted plate 109 is located outside the feed hopper 2. A return plate 1010 is slidably connected to the lower outer side of the feed hopper 2. The front and rear sides of the bottom of the return plate 1010 are symmetrically connected to the left and right outer sides of the feed hopper 2 with return springs 1011 respectively. The front sides of the left and right L-shaped rods 1012 are slidably connected to the inner sides of the left and right slotted plates 109 respectively. When the L-shaped rod 1012 moves, the L-shaped rod 1012 can drive the slotted plate 109 to swing. A U-shaped rod 1014 is fixedly connected to the front side of the bottom of the return plate 1010. A cam 1013 is fixedly sleeved on the rear side of the output shaft of the servo motor 105. The cam 1013 corresponds to the U-shaped rod 1014. When the cam 1013 rotates and contacts the U-shaped rod 1014, the cam 1013 can drive the U-shaped rod 1014 to move downward.

[0033] Initially, the air jet pipe 72 is externally connected to an air pump. First, the device is erected above the vibrating screen. Subsequently, the vibration motor 7 is started. Under the action of the connecting spring 5, the vibration motor 7 vibrates the vibrating plate 4, and the vibrating plate 4 vibrates the material receiving plate 6. Then, the externally connected air pump is started to discharge air into the air jet pipe 72, and the air jet pipe 72 ejects the air at high speed. Subsequently, an appropriate amount of ore is poured into the feed hopper 2, and the ore is blocked by the opening and closing plate 108. The servo motor 105 is started to rotate forward, driving the cam 1013 and the driving rod 107 to rotate forward. The cam 1013 rotates forward and contacts the U-shaped rod 1014. The cam 1013 drives the U-shaped rod 1014 to move downward. The U-shaped rod 1014 drives the return plate 1010 to move downward, and the return spring 1011 is compressed. The return plate 1010 drives the L-shaped rod 1012 to move downward, and the L-shaped rod 1012 drives the one-hole plate 109 to swing downward. The one-hole plate 109 drives the opening and closing plate 108 to swing downward and open, and the ore then falls downward into the groove directly above the slotted cylinder 101. As the cam 1013 continues to rotate forward and disengages from the U-shaped rod 1014, due to the action of the return spring 1011, the return plate 1010 drives the one-hole plate 109 to swing upward and reset through the L-shaped rod 1012. The one-hole plate 109 drives the opening and closing plate 108 to swing upward and reset to block the remaining ore in the feed hopper 2. At the same time, the driving rod 107 rotates forward and contacts the groove of the sprocket 103. The driving rod 107 drives the sprocket 103 to rotate reversely by 90 degrees. The sprocket 103 drives the slotted cylinder 101 to rotate reversely by 90 degrees. The slotted cylinder 101 rotating reversely by 90 degrees drives the ore to rotate reversely by 90 degrees to correspond to the dryer 102. The dryer 102 is started to dry the impurities on the ore. Since the opening and closing plate 108 blocks the remaining ore, it can prevent the ore from falling into the gap between the slotted cylinder 101 and the guide frame 10 and affecting the rotation of the slotted cylinder 101. The driving rod 107 continues to rotate forward and disengages from the sprocket 103. Subsequently, the cam 1013 continues to rotate forward and drives the U-shaped rod 1014 to move downward, causing the opening and closing plate 108 to swing downward and open. Part of the ore continues to fall into the groove directly above the slotted cylinder 101, and the slotted cylinder 101 continues to rotate reversely to drive the ore to rotate reversely. The dried ore rotates to the lower part and falls onto the guide plate 3, and the undried ore rotates to correspond to the dryer 102. Repeating this way, the ore can intermittently fall to remove impurities and complete the pretreatment, preventing a large amount of ore from falling and accumulating together and affecting the pretreatment. The ore on the guide plate 3 falls onto the material receiving plate 6 in the upper left corner. The vibrating plate 4 and the material receiving plate 6 vibrate to vibrate the ore, causing the impurities on the ore to fall off and separating the impurities from the ore. Then, the telescopic rod of the electric push rod 9 is extended to drive the connecting plate 91 to move downward. The connecting plate 91 drives the hook 92 to move downward. The hook 92 drives the contact rod 83 and the round rod 93 to move downward. The contact rod 83 drives the movable plate 82 to move downward. The movable plate 82 drives the wire 81 to move downward. The wire 81 drives the vibrating plate 4 to move in the direction of the conduit 8 through the conduit 8, and the connecting spring 5 is compressed.The vibrating plate 4 drives the ore material to move towards the direction of the wire conduit 8 through the material receiving plate 6. When the round rod 93 moves downward and contacts the inclined surface of the trigger plate 84, the trigger plate 84 drives the round rod 93 to swing towards the direction of the housing 1. The swinging of the round rod 93 drives the hook 92 to rotate, and the torsion spring 94 is compressed. The hook 92 rotates and disengages from the contact rod 83. Due to the action of the connecting spring 5, the vibrating plate 4 moves away from the wire conduit 8. The vibrating plate 4 throws the vibrated ore material through the material receiving plate 6. At this time, the high-speed ejected air blows the impurities in the ore material into the discharge frame 71, and the impurities are discharged through the discharge frame 71. Since a filter screen is arranged inside the discharge frame 71, it can prevent the ore material from entering the discharge frame 71 and being discharged. The ore material after removing the impurities is thrown onto the right material receiving plate 6. Start the electric push rod 9 to drive the connecting plate 91 to move upward. The connecting plate 91 drives the hook 92 to move upward. The hook 92 drives the round rod 93 to move upward and disengage from the trigger plate 84. Due to the action of the torsion spring 94, the hook 92 rotates reversely and resets. The upward movement of the hook 92 causes the inclined surface to contact the contact rod 83. Due to the action of the torsion spring 94, the hook 92 slides over the contact rod 83 and resets. When the ore material vibrates to an appropriate time, perform the above operations again to make the vibrating plate 4 throw the ore material through the material receiving plate 6 to remove the impurities and complete the pretreatment. Repeatedly like this, the thrown ore material falls from the housing 1 onto the vibrating screen and is screened. In this way, through vibration and the high-speed ejected air, the impurities in the ore material can be removed to complete the pretreatment to prevent the impurities from adhering to the ore material and affecting the subsequent screening, thereby improving the screening effect. When all the ore materials are completed with the pretreatment and screened by the vibrating screen, turn off the electric push rod 9, the hook 92 stops moving, the vibrating plate 4 and the material receiving plate 6 stop moving. Then turn off the servo motor 105, the driving rod 107 stops driving the sheave 103 to rotate, the opening and closing plate 108 stops swinging, and the grooved drum 101 stops rotating.

[0034] Please refer to Figure 9 and Figure 10 As shown, the ore selection vibrating screen feeding device with the function of ore material pretreatment further includes a material blocking assembly installed between the vibrating plate 4 and the material receiving plate 6. The material blocking assembly includes a material blocking plate 11, an elastic telescopic rod 111, and a blocking rod 112. The end parts of the left and right material receiving plates 6 close to each other are rotatably connected with a material blocking plate 11 respectively. The material blocking plate 11 can block the ore material on the material receiving plate 6. The upper part of the material blocking plate 11 and the vibrating plate 4 are rotatably connected with elastic telescopic rods 111 symmetrically in the front and back. The elastic telescopic rod 111 is composed of a sleeve, a rod, and a spring. The sleeve is rotatably connected to the material blocking plate 11, the rod is slidably connected in the sleeve, the end of the rod is rotatably connected to the vibrating plate 4, and the spring is connected between the end of the rod and the inner side of the sleeve. The front and back sides inside the housing 1 are symmetrically and fixedly connected with blocking rods 112 up and down. The end part of the blocking rod 112 far from the vibrating plate 4 contacts the material blocking plate 11. When the material blocking plate 11 moves, the blocking rod 112 can drive the material blocking plate 11 to swing.

[0035] When the ore material drops onto the receiving plate 6, the baffle plate 11 can block the ore material on the receiving plate 6. Then, when the vibrating plate 4 moves towards the wire conduit 8, the vibrating plate 4 drives the baffle plate 11 to move towards the wire conduit 8 through the receiving plate 6. The blocking rod 112 then pushes the baffle plate 11 to swing downward, and the downward swing of the baffle plate 11 drives the elastic telescopic rod 111 to extend. The elastic telescopic rod 111 is stretched, and the baffle plate 11 stops blocking the ore material when it swings downward. When the vibrating plate 4 moves away from the wire conduit 8 and throws the ore material through the receiving plate 6, the receiving plate 6 drives the baffle plate 11 to move away from the wire conduit 8 and reset. The baffle plate 11 stops being limited by the blocking rod 112 when it resets. Due to the action of the elastic telescopic rod 111, the baffle plate 11 swings upward and resets to continue blocking the ore material. In this way, it can prevent the ore material from falling from the receiving plate 6 before vibration, thus ensuring that the ore material can be completely vibrated to complete the separation of impurities.

[0036] Please refer to Figure 11 As shown, the ore selection vibrating screen feeding device with ore material pretreatment function further includes rubber rollers 12. Three rubber rollers 12 are fixedly connected to the left and right sides of the front and rear sides of the shell 1 at equal intervals. The rubber rollers 12 are in contact with the vibrating plate 4. When the vibrating plate 4 resets, the rubber rollers 12 can buffer the vibrating plate 4.

[0037] When the vibrating plate 4 resets, the vibrating plate 4 is in contact with the rubber rollers 12, and the rubber rollers 12 buffer the vibrating plate 4. In this way, it can prevent the vibrating plate 4 from being damaged due to a violent reset and strong impact, thus ensuring the safety of the reset of the vibrating plate 4.

[0038] Finally, it is necessary to note that the above content is only used to help understand the technical solution of the present invention and should not be construed as a limitation on the protection scope of the present invention; non-essential improvements and adjustments made by those skilled in the art based on the above content of the present invention all fall within the scope required to be protected by the present invention.
