Description

Technical Field

[0001] This utility model relates to the field of mineral processing equipment technology, and in particular to an automatic material distribution device for a mineral processing and crushing system. Background Technology

[0002] In the mineral processing and crushing process, the double-layer vibrating screen is a key piece of equipment for the initial screening of ore due to its high-efficiency screening performance. After the ore is screened by the upper screen, ore larger than the upper screen aperture remains in the upper layer for further processing, while ore smaller than the lower screen aperture passes through the lower screen to the next process. Ore in the intermediate particle size range needs to be accurately introduced into the pre-disposal system for further separation. The accuracy of the distribution of this intermediate particle size has a crucial impact on the concentrate recovery rate and subsequent processing costs of the entire mineral processing process.

[0003] Traditional material distribution methods use a single steel plate as the distribution plate, connected to an external pressure handle, with the distribution process manually controlled. This manual control mode has several insurmountable drawbacks: 1. Mineral processing operations are typically continuous, high-intensity production. Relying on manual operation of the pressure handle for extended periods results in extreme labor intensity for workers, easily leading to fatigue and increased instability and inaccuracy in the distribution operation, thus affecting mineral processing indicators; 2. The mineral processing site environment is complex and harsh, filled with potential hazards such as ore dust, equipment noise, and ore splashes. Workers operating the distribution device at close range face significant threats to their personal safety; 3. Manual control makes it difficult to quickly and accurately adjust the opening of the distribution plate based on real-time material levels within the pre-throwing system, hindering intelligent dynamic material distribution control and impeding improvements in mineral processing efficiency and profitability. Utility Model Content

[0004] The present invention aims to solve the problems mentioned in the background art and provides an automatic material distribution device for a mineral processing and crushing system, which innovates the original outdated manual control mode of the pressure handle into a hydraulic automatic control mode, thereby reducing the labor intensity of workers, improving the safety of operation, and achieving precise and intelligent material distribution.

[0005] To achieve the above-mentioned utility model objectives, the present utility model adopts the following technical solution: an automatic material distribution control device for a mineral processing and crushing system, comprising a flap, a motor, and a support, wherein the flap is rectangular; a shaft is sleeved parallel to the bottom of the flap; bearings are fixed to the two ends of the shaft near the flap; a rotating structure is sleeved to one end of the shaft; one end of the rotating structure is telescopically connected to a hydraulic cylinder; one end of the hydraulic cylinder is connected to the motor electrical circuit; a support is fixedly connected to the bottom of the motor; a control box is provided on one side of the support; one end of the motor is connected to the control system inside the control box through a motor control line.

[0006] Furthermore, the rotating structure includes a torsion bar and a telescopic bar; a collar is welded to one end of the torsion bar; the collar is fixedly connected to one end of the shaft; a long strip-shaped groove is provided in the middle of the other end of the torsion bar; the groove is movably connected to one end of the telescopic bar through a movable shaft; the other end of the telescopic bar is inserted into the inside of the piston rod at one end of the hydraulic cylinder.

[0007] Furthermore, a power indicator light and a running indicator are provided on the upper part of one side panel of the control box; a forward rotation button and a reverse rotation button are provided in the middle of one side panel of the control box; and a forward rotation limit switch and a reverse rotation limit switch are provided on the lower part of one side panel of the control box.

[0008] Furthermore, the control system inside the control box consists of a forward contactor coil, a reverse contactor coil, a circuit breaker, a forward contactor, and a reverse contactor. The forward contactor engages, causing the motor to rotate forward. The flip-plate mechanically operates the forward limit switch, whose normally closed contact disconnects the forward contactor coil and whose normally open contact connects the reverse contactor coil, causing the reverse contactor coil to engage and the motor to rotate in reverse. When the flip-plate reaches the reverse limit switch, the reverse limit switch activates, its normally closed contact disconnects the reverse contactor, and its normally open contact connects the forward contactor, causing the motor to rotate forward. This process repeats.

[0009] Furthermore, the bottom ends of the flap are respectively provided with circular ear plates; the flap is fixedly connected to the shaft through the ear plates.

[0010] Furthermore, the control box panel is equipped with multiple label plates.

[0011] Compared with the prior art, this utility model has the following advantages:

[0012] This device automatically controls the rotation of the tilting plate using motors, hydraulic cylinders, and other structures, eliminating the need for prolonged manual operation and significantly reducing worker fatigue. Simultaneously, automatic control avoids inaccurate material distribution caused by human fatigue, improving the stability and accuracy of the material distribution operation, thereby contributing to improved mineral processing indicators. The automatic material distribution control device eliminates the need for close-range manual operation, reducing worker contact with hazardous environments and effectively ensuring worker safety. The control box contains a control system composed of forward and reverse contactor coils, circuit breakers, and forward and reverse contactors. It achieves automatic control through forward and reverse limit switches and can quickly and accurately adjust the opening of the material distribution plate based on the real-time material level in the pre-disposal system, realizing intelligent dynamic material distribution control, which is beneficial for improving mineral processing efficiency and profitability.

Detailed Implementation

[0018] The technical solution of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model: An automatic material distribution control device for a mineral processing and crushing system includes a flap 1, a motor 7, and a support 8. The flap 1 is rectangular; a shaft 2 is sleeved parallel to the bottom of the flap 1; bearings 12 are fixed to the two ends of the shaft 2 near the flap 1; a rotating structure is sleeved at one end of the shaft 2; one end of the rotating structure is telescopically connected to a hydraulic cylinder 6; one end of the hydraulic cylinder 6 is electrically connected to the motor 7; the bottom of the motor 7... A support 8 is fixedly connected to the main unit, and the support 9 is stably installed in the predetermined position of the mineral processing and crushing system to ensure that it is firmly installed and can withstand the vibration and load of the entire device during operation. A control box 9 is provided on one side of the support 8. One end of the motor 7 is connected to the control system inside the control box 9 through a motor control line. The flap 1 is fixedly connected to the shaft 2 through the circular ear plates 14 at both ends of the bottom, ensuring that the ear plates 14 and the shaft 2 are tightly fitted, effectively ensuring that the flap 1 can rotate flexibly on the shaft 2 without displacement or shaking during rotation. When installing the bearings 12 near the two ends of the shaft 2 of the flap 1, an appropriate amount of grease should be applied to reduce rotational friction, extend the service life of the bearings, and ensure smooth rotation of the flap 1.

[0019] Furthermore, the rotating structure includes a torsion bar 3 and a telescopic bar 4; a collar 301 is welded to one end of the torsion bar 3; the collar 301 is fixedly connected to one end of the shaft 2; a long strip-shaped groove 302 is provided in the middle of the other end of the torsion bar 3; the groove 302 is movably connected to one end of the telescopic bar 4 through a movable shaft 11; the other end of the telescopic bar 4 is inserted into the inside of the piston rod 5 at one end of the hydraulic cylinder 6. The collar 301 at one end of the torsion bar 3 in the rotating structure is precisely fixed to one end of the shaft 2, and the connection is firm and reliable by welding. The long strip-shaped groove 302 in the middle of the other end of the torsion bar 3 is movably connected to one end of the telescopic bar 4 through a movable shaft 11. A groove is provided at the connection between the telescopic bar 4 and the groove 302, which can effectively ensure that the telescopic bar 4 can freely extend and retract within the groove 302 without jamming.

[0020] Furthermore, a power indicator light 901 and a running indicator 902 are provided on the upper part of one side panel of the control box 9; a forward rotation button 903 and a reverse rotation button 904 are provided in the middle of one side panel of the control box 9; and a forward rotation limit switch 905 and a reverse rotation limit switch 906 are provided on the lower part of one side panel of the control box 9.

[0021] Furthermore, the control system inside the control box 9 consists of a forward contactor coil 15, a reverse contactor coil 16, a circuit breaker 17, a forward contactor 18, and a reverse contactor 19. The forward contactor 18 engages the motor 7 to run in the forward direction. The flap 1 mechanically operates the forward limit switch 905, the normally closed contact of the forward limit switch 905 disconnects the forward contactor coil 15, and the normally open contact connects the reverse contactor coil 16, causing the reverse contactor coil 16 to engage and the motor 7 to reverse direction. When the flap 1 reaches the reverse limit switch 906, the reverse limit switch 906 actuates, the normally closed contact disconnects the reverse contactor 19, and the normally open contact connects the forward contactor 18, causing the motor 7 to run in the forward direction.

[0022] Furthermore, the control box 9 is provided with multiple labels 12. The labels 12 on the control box 9 can be used to clearly indicate the functions and operating instructions of each button, indicator light and switch, so that operators can quickly identify and operate them.

[0023] In operation, for manual start-up, press the forward rotation button 903 located in the middle of one side panel of control box 9. The motor 7 will then begin forward rotation under the engagement of the forward rotation contactor 18. The operator can observe the rotation of the flap 1 to determine if the device is functioning correctly. The flap 1 rotates smoothly in the predetermined direction as the motor 7 rotates forward, and the bearings 12 at both ends of the shaft 2 should operate smoothly during this rotation. For reverse operation, press the reverse rotation button 904. The motor 7 will then reverse under the action of the reverse rotation contactor 19, and the flap 1 will also reverse. During manual control, the operator can flexibly adjust the angle of the flap 1 according to the actual needs of ore distribution on site to achieve preliminary material distribution control.

[0024] In automatic operation, when the device switches to automatic control mode, there is no need for manual continuous pressing of the forward or reverse buttons. As the mineral processing progresses, the ore is continuously conveyed to the distribution position. When the flap 1 mechanically moves to the forward limit switch 905, the normally closed contact of the forward limit switch 905 disconnects the forward contactor coil 15, and the normally open contact connects the reverse contactor coil 16. The reverse contactor coil 16 engages, the motor 7 automatically reverses, and the flap 1 begins to rotate in the reverse direction. Similarly, when the flap 1 reaches the reverse limit switch 906, the reverse limit switch 906 activates, the normally closed contact disconnects the reverse contactor 19, and the normally open contact connects the forward contactor 18, and the motor 7 resumes forward rotation. This cycle repeats continuously, and the device can automatically adjust the rotation direction of the flap 1 according to the preset limit conditions, realizing the precise introduction of ore particles between the upper and lower screen apertures into the pre-disintegration system for further separation. During automatic control operation, operators only need to observe the operation indicator 902 on the control box 9 and periodically check the operating status of each component of the device to ensure continuous and stable operation of the device.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model based on the technical solution and its improved concept should be covered within the protection scope of the present utility model.
