A lower stirring paddle support rod is provided on the lower base. A lower motor is provided at the top of the lower stirring paddle support rod, and a lower stirring paddle is provided on the lower motor.

[0004] Although the above-mentioned patented uniform feeding device for a thickener is not only simple in structure and easy to operate, but also reduces the load on the thickener during operation and greatly improves the working efficiency of the thickener, some residual material will remain on the surface of the inlet during feeding, causing some waste and making it inconvenient for later cleaning. Moreover, at the end of feeding, the material may become blocked, affecting the conveying efficiency. Therefore, a feeding device for a target thickener is proposed to address the above problems. Utility Model Content

Furthermore, material blockage at the end of the feeding process affects the efficiency of conveying. This invention proposes a feeding device for a target-type concentrator.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A feeding device for a target-type thickener, comprising a trough; a beam is provided at the top of the trough, a platform is provided at the middle of the top of the beam, a feeding hopper is provided at the middle of the bottom of the beam, a driving mechanism is provided at the top of the platform, a rotating rod is provided at the bottom of the driving mechanism, the bottom end of the rotating rod passes through the inside of the feeding hopper and is fixedly connected to a rake frame, a feeding hopper is provided on one side edge of the top of the trough, a connecting square tube is provided at the bottom of the feeding hopper, a feeding assembly is provided at one end of the connecting square tube, and a striking assembly is provided on the side of the feeding hopper; the feeding assembly includes a feeding pipe connected to the connecting square tube, and a U-shaped tube is sleeved inside the feeding pipe. Spring A is equidistantly arranged on both sides of the bottom, and the bottom end of the spring A is fixedly connected to the inner bottom surface of the feed tube. A vibration motor is installed at the bottom of the U-shaped tube. Limiting rods are equidistantly arranged on both sides of the U-shaped tube. Limiting holes are opened equidistantly on both sides of the feed tube. The limiting rods are sleeved inside the limiting holes, and the diameter of the limiting holes is larger than the diameter of the limiting rods. The striking assembly includes a clamping plate on the side of the feeding hopper. A rocker arm is movably connected to the surface of the clamping plate. A striking hammer is installed at one end of the rocker arm. Spring B is installed on one side of the striking hammer. One end of Spring B is fixedly connected to the surface of the feeding hopper. An electric telescopic rod is installed on one side of the clamping plate. Arc-shaped grooves are opened equidistantly at the telescopic end of the electric telescopic rod. An arc-shaped locking block that matches the arc-shaped groove is installed at the other end of the rocker arm.

[0007] Preferably, the inner bottom of the connecting square tube is inclined and a discharge trough is opened on the side. A guide plate is provided in the inner bottom of the discharge trough. One end of the guide plate is inserted into the U-shaped tube, and one end of the feeding pipe is connected through to the side of the feeding barrel.

[0012] The advantages of this utility model are:

[0013] 1. This utility model achieves a misaligned engagement between the arc-shaped groove at the telescopic end of the electric telescopic rod of the striking component and the arc-shaped locking block of the rocker arm. The electric telescopic rod reciprocates, and the arc-shaped groove pushes the arc-shaped locking block to deflect. The rocker arm swings around the clamp fulcrum, and the B spring stores and rebounds, driving the striking hammer to strike the side wall of the feeding hopper at high frequency, shaking off the residual material on the inner wall. This solves the waste and cleaning problems caused by the residual material adhering to the inner wall of the feeding hopper.

[0014] 2. This utility model uses a U-shaped tube of the feeding assembly to form an elastic vibration structure through a vibration motor and spring A. The vibration motor excites the U-shaped tube to vibrate slightly up and down along the gap between the limiting rod and the limiting hole. Combined with the continuous flow guide surface design of the inclined inner bottom of the connecting square tube and the guide plate, the material can smoothly slide into the feeding tube and be transported to the feeding bucket, which solves the problem of blockage at the end of the material conveying and improves the feeding efficiency.

A vibration motor 104 is installed at the bottom of the U-shaped tube 102. Limiting rods 105 are equidistantly arranged on both sides of the U-shaped tube 102. Limiting holes 106 are equidistantly opened on both sides of the feeding tube 101. The limiting rods 105 are sleeved inside the limiting holes 106, and the diameter of the limiting holes 106 is larger than the diameter of the limiting rods 105. The striking assembly 11 includes a clamping piece 111 on the side of the feeding hopper 8. A rocker arm 112 is movably connected to the surface of the clamping piece 111. A striking hammer 113 is installed at one end of the rocker arm 112. A B spring 114 is installed on one side of the striking hammer 113. One end of the B spring 114 is fixedly connected to the surface of the feeding hopper 8. An electric telescopic rod 115 is installed on one side of the clamping piece 111. Arc-shaped grooves 116 are equidistantly opened at the telescopic end of the electric telescopic rod 115. An arc-shaped locking block 117 that matches the arc-shaped groove 116 is installed at the other end of the rocker arm 112.

[0023] During operation, the drive mechanism 5 on the support platform 3 via the main beam 2 at the top of the trough 1 drives the rotating rod 6 to rotate the rake frame 7 inside the feeding bucket 4; the material in the feeding hopper 8 slides into the U-shaped tube 102 of the feeding assembly 10 through the inclined inner bottom of the connecting square tube 9; the vibration motor 104 and spring A 103 cooperate to make the U-shaped tube 102 vibrate up and down along the limiting rod 105 to promote material conveying; the extension end of the electric telescopic rod 115 of the striking assembly 11 moves the arc-shaped locking block 117 of the rocker arm 112 through the arc-shaped groove 116, and the spring B 114 rebounds to drive the striking hammer 113 to strike the side wall of the feeding hopper 8; the high-frequency vibration of the striking assembly 11 removes the residual material on the inner wall of the feeding hopper 8 and reduces waste; the vibration structure of the U-shaped tube 102 prevents material blockage and improves conveying efficiency.

[0024] Furthermore, the inner bottom of the connecting square tube 9 is inclined and the side has a discharge trough 12. The inner bottom of the discharge trough 12 is provided with a guide plate. One end of the guide plate is inserted into the U-shaped tube 102, and one end of the feeding pipe 101 is connected to the side of the feeding barrel 4.

[0025] During operation, the inclined inner bottom of the connecting square tube 9 guides the material to slide towards the discharge chute 12. The guide plate extends to the top of the U-shaped tube 102 inlet to form a continuous flow path. The material enters the U-shaped tube 102 through the guide plate. The continuous flow surface of the inclined inner bottom and the guide plate optimizes the material conveying path and reduces the risk of material jamming.

[0026] Furthermore, the extension direction of the electric telescopic rod 115 of the striking component 11 is perpendicular to the swing trajectory of the arc-shaped locking block 117, and the curvature of the arc-shaped groove 116 matches the outer contour of the arc-shaped locking block 117.

[0027] During operation, the extension and retraction direction of the electric telescopic rod 115 is perpendicular to the swing direction of the arc-shaped locking block 117. When the electric telescopic rod 115 extends, the arc-shaped groove 116 at its end pushes the arc-shaped locking block 117 to deflect and disengage. The vertical motion design ensures stable triggering of the strike, and the matching of the arc-shaped groove 116 and the arc-shaped locking block 117 improves the accuracy of the action.

[0028] Furthermore, the vibration motor 104 of the U-shaped tube 102 and the spring A 103 form an elastic vibration structure, and the clearance fit between the limiting rod 105 and the limiting hole 106 allows the U-shaped tube 102 to vibrate slightly up and down.

[0029] During operation, the vibration motor 104 of the U-shaped tube 102 generates high-frequency vibration. Spring A 103 absorbs the vibration energy and allows the U-shaped tube 102 to move slightly up and down along the gap between the limiting rod 105 and the limiting hole 106. The elastic vibration structure enhances the material loosening effect, and the gap fit between the limiting rod 105 and the limiting hole 106 prevents the U-shaped tube 102 from vibrating and shifting.

[0030] Furthermore, the inclined inner bottom of the connecting square tube 9 and the guide plate of the discharge trough 12 form a continuous flow guide surface, and the end of the guide plate extends to the top of the inlet of the U-shaped tube 102.

[0031] During operation, the end of the guide plate extends directly above the inlet of the U-shaped tube 102, and the inclined guide surface is seamlessly connected to the inlet of the U-shaped tube 102. The connection design between the guide plate and the U-shaped tube 102 ensures that the material falls accurately into the vibration zone and avoids scattering.

[0032] Furthermore, the drive mechanism 5 includes a combination structure of a motor and a reducer, and anti-loosening bolts are provided at the connection between the rotating rod 6 and the rake frame 7;

[0033] During operation, the combination of motor and reducer in drive mechanism 5 drives the rotating rod 6 to rotate at a constant speed. The anti-loosening bolts fix the connection between the rotating rod 6 and the rake frame 7. The combination of motor and reducer ensures the stable speed of the rake frame 7, and the anti-loosening bolts enhance the reliability of the transmission structure.

[0034] Working principle: The drive mechanism 5 drives the rotating rod 6 to rotate the rake frame 7 in the feeding bucket 4 to agitate the material. The material in the feeding hopper 8 slides into the U-shaped tube 102 of the feeding assembly 10 through the inclined inner bottom of the connecting square tube 9. The vibration motor 104 and spring A 103 cooperate to make the U-shaped tube 102 vibrate up and down along the gap between the limiting rod 105 and the limiting hole 106 to promote material conveying. The extension end of the electric telescopic rod 115 of the striking assembly 11 moves the arc-shaped locking block 117 of the rocker arm 112 through the arc-shaped groove 116. The rebound of spring B 114 drives the striking hammer 113 to strike the side wall of the feeding hopper 8 at high frequency to shake off the residual material. The guide plate guides the material in the discharge chute 12 of the connecting square tube 9 into the U-shaped tube 102. The combination of the motor and reducer of the drive mechanism 5 ensures the stable speed of the rake frame 7. The anti-loosening bolts strengthen the connection between the rotating rod 6 and the rake frame 7. The inclined inner bottom and the guide plate form a continuous guiding surface to optimize the material path.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
