[0002] When screening different minerals in ore sand, a shaker is often used. Water is added to the ore sand to create a slurry. Based on the varying densities of the various minerals in the slurry, the shaking water in the shaker separates the minerals and is then recovered using a receiving device. During the slurry feeding process, it is crucial to ensure a uniform concentration of slurry flowing into each shaker. Existing shaker feeding devices struggle to ensure this uniformity. Summary of the Invention

[0003] The present invention is aimed at the above problems and specifically designs a shaking table uniform feeding device and feeding method to improve the uniformity of feeding of the feeding device.

[0004] To achieve the above-mentioned purpose, the present invention provides a shaking table uniform feeding device, comprising a distribution tank, a distribution cover, and a stirring mechanism rotatably connected to the distribution cover, the distribution tank and the distribution cover are both cavity structures and the distribution cover is arranged in the distribution tank, the feed port of the distribution cover is provided with an ore feed pipe connected to the main ore pipe slurry, a plurality of slurry holes 1 are opened at the bottom of the distribution cover, a plurality of slurry holes 2 are opened at the bottom of the distribution tank, a connecting pipe is fixedly extended at the slurry hole 2, and the connecting pipe is connected to the shaking table through the discharge pipe.

[0005] Furthermore, the stirring mechanism includes a power source 1, a rotating shaft and a stirring paddle. The distribution tank is fixedly connected to a top plate. The outer shell of the power source 1 is fixedly connected to the top plate and the output shaft is driven to connect to the rotating shaft. The stirring paddle is arranged in the equal distribution cover.

[0006] Preferably, the stirring paddle is cross-shaped, comprising arc-shaped paddle plates arranged vertically and staggered, and flow guide notches are provided at the edges of the paddle plates.

[0007] Preferably, a frustum-shaped slope is provided in the middle of the bottom of the equilibrating cover cavity, and a turbulent groove is provided at the bottom of the side wall of the equilibrating cover.

[0008] Furthermore, the connecting pipe is provided with a branch pipe with an axis perpendicular to the axis, and a flow regulating assembly is installed in the branch pipe. The branch pipe includes a first branch pipe and a second branch pipe. One end of the first branch pipe is fixedly connected to the connecting pipe, and the other end is connected to the second branch pipe through a clamp.

[0009] Furthermore, the flow regulating assembly includes a second power source, a straight tooth bevel group, a rotating rod and an adjusting plate. The second power source is installed at the bottom of the distribution tank and the output shaft drives the driving wheel in the straight tooth bevel group. The driving wheel engages the driven wheel. One end of the rotating rod cooperates with the driven wheel, and the other end is inserted into the branch pipe and fixedly connected to the adjusting plate. The adjusting plate is rotatably arranged in the connecting pipe; the rotating rod is rotatably connected to the second branch pipe through a bearing, and a sealing gasket is installed between the second branch pipe and the first branch pipe.

[0013] The present invention also includes a feeding method for a shaking table uniform feeding device, comprising the following steps:

[0014] 1) The ore slurry is fed into the cavity of the equilibrating cover through the ore inlet pipe and flows evenly to the bottom of the equilibrating cover along the slope. Part of the ore slurry flows directly into the distribution tank through the lower slurry hole, while the other part of the ore slurry is blocked by the side wall of the equilibrating cover. Under the influence of turbulent grooves and reaction forces, the ore slurry fluctuates to form waves, which fall back to the bottom of the equilibrating cover, and the impact force generated washes the ore on the bottom wall;

[0015] 2) While injecting material into the ore inlet pipe, start the stirring mechanism to further mix the mortar;

[0016] 3) The ore slurry in the cavity of the distribution tank is evenly distributed to the connecting pipe through each slurry discharge hole, and finally transported to multiple shaking tables through the discharge pipe;

[0017] 4) When the feed rate needs to be controlled, the effective discharge diameter of the connecting pipe can be adjusted through the flow regulating component.

[0018] In summary, the present invention has the following advantages and beneficial technical effects:

[0019] 1. The frustum-shaped slope design of the equilibrating cover in the present invention can buffer and evenly distribute the mineral slurry, allowing the mineral slurry to flow evenly into each lower slurry hole. The design of the turbulent groove allows the mineral slurry to spread evenly after hitting the inner wall of the equilibrating cover, forming waves with the help of its own structure. The waves fall back to the bottom of the equilibrating cover, and use the impact force to further wash away the solid mortar deposited on the bottom wall.

[0020] 2. The stirring mechanism of the present invention utilizes the rotation of the paddle to promote the mixing of water and ore sand; the provision of the guide notch removes part of the resistance of the ore sand slurry to the blade when the paddle is started.

[0021] 3. The flow regulating assembly of the present invention utilizes the meshing transmission of the straight tooth bevel group to drive the regulating plate to rotate synchronously, thereby changing the closing angle of the connecting pipe, and controlling the feeding amount by adjusting the effective discharge pipe diameter of the connecting pipe, thereby enhancing the controllability of the device.

[0022] 4. The detachable design of the lifting assembly in the present invention improves the neatness of the device parts and reduces the impact on the operation of the stirring mechanism; the symmetrical plug-in block 1 and plug-in block 2 enhance the stability of the lifting; the limit plate group and the screw nut work together to lock the position of the lifting ear and limit the deformation of the L-shaped slot opening.

[0023] 5. The supporting base of the present invention is used to mount the dispensing tank on the shaking table. BRIEF DESCRIPTION OF THE DRAWINGS

The stirring paddle rotates synchronously with the rotating shaft 32 to further mix the mortar in the evenly distributed cover 2.

[0051] Step 3: The ore slurry flowing into the cavity of the distribution tank 1 is evenly distributed to the connecting pipe 12 through each slurry discharge hole 11, and finally transported to multiple shaking tables along the discharge pipe 13;

[0052] Step 4: When the feeding amount needs to be controlled, the power source 2 61 of the flow regulating assembly 6 is started, the motor outputs power and drives the straight bevel group to realize meshing transmission, the rotating rod 64 and the adjusting plate 65 rotate synchronously with the driven wheel 63, changing the area of ​​the connecting pipe 12 covered by the adjusting plate 65, thereby adjusting the effective discharge diameter of the connecting pipe 12.

[0053] Finally, it should be noted that the above embodiments are intended only to illustrate the technical solutions of the present invention and are not intended to limit the present invention.
