Abstract
Description
Technical Field

[0002] The pendulum feeder is a mechanical device that realizes continuous and uniform feeding. It is installed under the storage tank or hopper and often feeds conveyor belts, ball mills and other equipment. In order to determine the feeding size of the pendulum feeder, an electronic belt scale is usually installed on the unloading belt of the pendulum feeder. The premise for the accurate measurement of the electronic belt scale is that the belt material is evenly distributed and calibrated regularly.
[0003] The working principle of the swing feeder is to install a fan-shaped gate at the discharge port of the ore bin. The gate is decelerated by the electric motor through the worm gear, and swings in an arc through the eccentric shaft and the pull rod. When the gate moves forward, the discharge port is closed, and when the gate moves backward, the discharge port is opened to unload the ore.
[0004] Therefore, this type of feeder can feed ore intermittently and evenly. Since the feeding method is intermittent, the materials distributed on the belt conveyor are unevenly distributed, resulting in large measurement errors of the electronic belt scale, and the measurement data cannot serve subsequent production. At the same time, the traditional swing feeder also has no quantitative feeding calculation system, and cannot realize automatic adjustment of the feeding amount. Utility Model Content

[0025] Example 1
[0026] like Figure 1 As shown, the utility model provides a technical solution:
[0027] A quantitative feeding pendulum feeder, which at least includes but is not limited to a feeding mechanism 1, a conveying mechanism 2 and a measurement and control mechanism 3; an arc-shaped jaw plate 11 is provided at the outlet of the feeding mechanism 1, one end of the arc-shaped jaw plate 11 is hinged to the outlet of the feeding mechanism 1, a power mechanism 4 is provided between the arc-shaped jaw plate 11 and the feeding mechanism 1, an end of the power mechanism 4 is hinged to the arc-shaped jaw plate 11, the conveying mechanism 2 is provided at the outlet of the feeding mechanism 1, a detection part and a control part are provided in the measurement and control mechanism 3, the height position of the detection part is the same as the horizontal position when the arc-shaped jaw plate 11 moves to the highest limit position, and the control part is connected to the power mechanism 4; the detection part is used to detect the number of swings of the arc-shaped jaw plate 11, and the control part is used to control the rotation speed of the motor in the power mechanism 4.
[0028] Based on the above structure, in the prior art, an electronic belt scale is usually used to weigh the material that falls on the belt. However, the material that falls on the belt will be deflected due to the rotation of the pulley, or the intermittent feeding method will cause the material to be unevenly distributed on the belt conveyor, resulting in a large measurement error of the electronic belt scale. Therefore, this scheme eliminates the electronic belt scale and controls the number of movements of the arc-shaped jaw plate 11 to achieve overall material control. Since the ore is first crushed to a relatively uniform state before being passed into the feeding mechanism 1, when the arc-shaped jaw plate 11 moves from the initial position to the extreme position, the material that falls from the feeding mechanism 1 each time is basically consistent. By controlling the number of rotations of the arc-shaped jaw plate 11, the total amount of material entering the conveying mechanism can be determined relatively accurately, solving a series of problems of uneven feeding of traditional pendulum feeders leading to large measurement errors.
[0029] As an example, the feeding mechanism 1 may include a material holding chamber 12 and a discharge end 13. The material holding chamber 12 is a funnel-shaped structure as a whole. The bottom opening of the material holding chamber 12 is set, and the top opening of the discharge end 13 is set. The open end of the discharge end 13 is connected to the bottom of the material holding chamber 12. The bottom of the discharge end 13 is provided with an arc-shaped opening 14, and the arc-shaped jaw plate 11 is sleeved on the outer side of the arc-shaped opening 14 of the discharge end 13.
[0030] Based on the above structure, the material is piled in the material holding chamber 12, and then gradually falls onto the conveying mechanism 2 as the material is discharged from the discharge end 13. Since the discharge end 13 is provided with an arc-shaped opening 14, the material will not fall directly, but will accumulate at the arc-shaped opening 14. As the arc-shaped jaw plate 11 rotates, the material accumulated at the arc-shaped opening 14 will fall.
[0031] As an example, the power mechanism 4 may include a support plate 41, a rotating chamber 42, a power motor 43, an eccentric wheel 44 and a connecting rod 45; the support plate 41 is connected to the side wall of the discharge end 13, the rotating chamber 42 is arranged at the lower position of the support plate 41, and the output end of the power motor 43 is connected to the eccentric wheel 44 through a coupling and a gear structure. Under the action of the power motor 43, the eccentric wheel 44 rotates eccentrically, one end of the connecting rod 45 is hinged to the eccentric wheel 44, and the other end is hinged to the bottom of the arc-shaped jaw plate 11.
[0032] Based on the above structure, the power motor 43 provides power for the rotation of the eccentric wheel 44, so that the side of the eccentric wheel 44 is connected to the rotating shaft, and the eccentric wheel 44 rotates around the center position of the rotating shaft. The rotation of the deflection wheel will drive the connecting rod 45 to rotate, and the connecting rod 45 will drive the arc-shaped jaw plate 11 to reciprocate, finally realizing the gap dropping of the material.
[0033] As an example, a hinge seat 46 is provided at the bottom of the arc-shaped jaw plate 11, a rotating shaft 47 is provided at the center of the hinge seat 46, the connecting rod 45 is connected to the rotating shaft 47, at least two hinge seats 46 are provided at the bottom of the arc-shaped jaw plate 11, and the rotating shaft 47 is provided between at least two hinge seats 46;
[0034] The eccentric wheel 44 and the connecting rod 45 are symmetrically arranged on both sides of the arc-shaped jaw plate 11 along the center position of the power motor 43. By pushing the arc-shaped jaw plate 11 through the two connecting rods 45, the output force can be more balanced, the eccentric wear can be reduced, and the service life of the product can be extended.
[0035] As an example, a material guide trough 48 may be provided at the lower side of the discharge end 13 , and the upper and lower ends of the material guide trough 48 are opened. An inspection groove 49 may be provided on the material guide trough 48 near the eccentric wheel 44 .
[0036] Based on the above structure, the material is guided from the discharge end 13 to the conveying mechanism 2 through the guide trough 48 to avoid spilling of the material. At the same time, an inspection groove 49 is provided on the guide trough 48 to facilitate the inspection of the hinge between the eccentric wheel 44 and the connecting rod 45.
[0037] As an example, the measurement and control mechanism 3 may include an infrared counter 31, a connecting bracket 32 and a control box 33. The connecting bracket 32 may be arranged on the side wall of the material guide trough 48, and the infrared counter 31 is arranged on the connecting bracket 32. The emitting end of the infrared counter 31 is facing the arc-shaped jaw plate 11, and the position of the emitting end of the infrared counter 31 matches the height position at the extreme position of the arc-shaped jaw plate 11.
[0038] Based on the above structure, when the arc-shaped jaw plate 11 moves to the extreme position, no material will be spilled. At this time, counting detection is performed by the infrared counter 31, which can avoid external interference and improve the counting accuracy.
[0039] As an example, a PID operator 34 and a frequency converter 35 may be provided in the control box. The frequency converter 35 is connected to the power motor 43 , and the PID operator 34 is connected to the infrared counter 31 ; the PID operator 34 is connected to the frequency converter 35 .
[0040] Based on the above structure, when in use, the staff inputs the quantitative feed amount into the PID operator 34, and the operator calculates the swing times per minute of the swing feeder according to the feed amount = 60 * single pendulum weight * swing times per minute, and then converts the swing times into an electrical signal, and controls the motor speed to reach the predetermined swing times through the frequency converter 35. In order to verify that the entire feeding system always works according to the preset value, the infrared counter 31 continuously monitors the number of arc-shaped jaws 11, and then feeds back to the PID operator 34, so as to realize closed-loop control.
[0041] As an example, the conveying mechanism 2 may include a transmission roller 21 and a transmission belt 22 . The transmission belt 22 is sleeved on the transmission roller 21 , and the central axis of the transmission belt 22 is colinear with the central position of the output port of the guide trough 48 .
[0042] Based on the above structure, the transmission roller 21 rotates to drive the transmission belt 22 to rotate, and finally the mineral material is transported stably.
[0043] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
