Among them:

[0017] In order to enable those skilled in the art to better understand the technical solutions in the embodiments of the present invention and to make the above-mentioned purposes, features and advantages of the present invention more obvious and understandable, the specific implementation methods of the present invention are further described below.

[0018] Please refer to Figure 1-3 The present invention provides a shaking table 100 for mineral processing, comprising a base 10, a bed surface 20 supported on the base 10, a feeding device 30 disposed on one side of the bed surface 20, and a driving device 40 connected to the bed surface 20 and used to drive the bed surface 20 to move along the base 10. The base 10, the bed surface 20, and the driving device 40 all adopt conventional structures in the art and are not described in detail in this embodiment.

[0019] The feeding device 30 includes an ore feeding chute 31 , a first enclosure 32 , a support 33 , a water feeding chute 34 and a second enclosure 35 .

[0020] The bed 20 is an inclined surface equipped with a riveting bar. Mineral particles are fed in through an inlet chute 31, while water is supplied horizontally through a water inlet chute 34. The combined effects of the inclined water flow and the asymmetric reciprocating motion of the bed 20 separate the particles into strata according to specific gravity and particle size, moving both longitudinally and transversely along the bed 20. Particles of varying specific gravity and particle size flow downward in a trapezoidal pattern, exiting at different locations on the concentrate and tailings sides, ultimately separating into concentrate, sub-concentrate, intermediate concentrate, and tailings. To move particles of varying densities from the drive end of the bed 20 toward the concentrate end, the drive device 40 must drive the bed 20 in an asymmetric motion. Specifically, the bed 20 transitions from forward travel to reverse travel more quickly, while the transition from reverse travel to forward travel is slower. The asymmetric reciprocating motion of the bed 20 imparts inertia to the mineral particles, causing them to move relative to the bed 20.

[0021] The ore feeding chute 31 is provided at the transmission end of the bed surface 20 . The ore feeding chute 31 is a trough-shaped structure with an open top, and ore particles are fed into the ore feeding chute 31 from the top opening. It should be noted that the transmission end refers to the end close to the driving device 30 .

[0022] The support platform 33 is spaced apart from the ore feed chute 31, and the first enclosure 32 cooperates with the ore feed chute 31 and the support platform 33 to form an ore feed chute 36. The bottom of the ore feed chute 31 is provided with an ore feed port connected to the ore feed chute 36, and the ore particles enter the ore feed chute 36 through the ore feed port.

[0023] The top of the support 33 is recessed to form a slot 330, and the bottom of the water inlet trough 34 protrudes to form a protrusion 340. The protrusion 340 is correspondingly locked in the slot 330. This connection method facilitates the installation and removal of the water inlet trough 34. At the same time, the position of the water inlet trough 34 is raised by the support 33, which can increase the flushing force of the water flowing out of the water inlet trough 34 and improve the flushing effect on the mineral particles.

[0024] The second enclosure 35 cooperates with the support platform 33 to form a water supply trough 37 .

[0025] The water inlet trough 34 is a trough-shaped structure with an opening at the top. Water is fed in from the top opening of the ore inlet trough 31. Water outlets are provided on both sides of the bottom of the water inlet trough 34. The two outlets are respectively located above the ore feeding trough 36 and the water feeding trough 37, and are used to feed water into the ore feeding trough 36 and the water feeding trough 37. The water in the water inlet trough 34 enters the ore feeding trough 36. On the one hand, it can wash away the mud and sand on the surface of the mineral particles. On the other hand, it can serve as a carrier of the mineral particles and carry the mineral particles to move onto the bed surface. A flushing water outlet is provided at the bottom of the side of the second enclosure 35 close to the bed surface 20, connecting the water feeding trough 37 and the space of the bed surface 20. The water entering the water feeding trough 37 is discharged through the flushing water outlet, providing horizontal flushing water to flush the mineral particles on the bed surface 20, providing a force for the mineral particles to move horizontally.

[0026] The first enclosure 32 includes a fixed plate 321 and a movable plate 322, and the fixed plate 321 and the movable plate 322 are relatively spaced apart. One end of the fixed plate 321 is fixed to the side wall of the ore feed chute 31, the other end is fixed to the side wall of the support platform 33, and the bottom is fixed to the bed surface 20; the movable plate 322 includes a plate body 3221, a pin 3222 and a rubber baffle 3223, and the number of the pins 3222 is two, and the two pins 3222 are arranged at opposite ends of the plate body 3221, one of the pins 3222 is hinged to the side wall of the ore feed chute 31, and the other pin 3222 is hinged to the side wall of the support platform 33. Specifically, the articulation is in the form of directly setting a through-hole matching the pin shaft 3222 on the side walls of the ore feed chute 31 and the support platform 33, and passing the pin shaft 3222 through the through-hole. At this time, the pin shaft 3222 can rotate freely in the through-hole, driving the movable plate 322 to rotate as a whole.

[0027] The rubber baffle 3223 is disposed at the bottom of the plate body 3221 and abuts against the bed surface 20. The length of the rubber baffle 3223 is the same as that of the plate body 3221, and the thickness is 1 / 5 of the thickness of the plate body 3221. By reducing the thickness of the rubber baffle 3223, the bending ability of the rubber baffle 3223 can be improved.

[0028] The rubber baffle 3223 has a certain degree of flexibility. When the mixture (including water and mineral particles) in the feed trough 36 is small, the mixture will first squeeze the rubber baffle 3223, causing the rubber baffle 3223 to bend toward the bed surface 20. At this time, a discharge port is correspondingly formed between the rubber baffle 3223 and the bed surface 20. The mixture can be discharged into the surface of the bed surface 20 through the discharge port. The bed surface 20 moves under the driving action of the driving device 40. The movement direction of the bed surface 20 is perpendicular to the discharge direction of the discharge port. The mineral particles are discharged along the bed surface 20 under the dual action of the water flow and the movement of the bed surface 20.

[0029] When the amount of mixed material in the feed trough 36 increases, the mixed material will squeeze the rubber baffle 3223 and the plate body 3221 at the same time, causing the movable plate 322 to rotate as a whole, further expanding the opening of the discharge port. At this time, the discharge speed of the discharge port increases, which can increase the mineral processing speed and prevent the mixed material from overflowing from the feed trough 36.

[0030] When the mixture in the feed chute 36 is reduced, the movable plate 322 will return to its original position under the action of gravity, and the rubber baffle 3223 will return to its original position under the action of elastic potential energy, and finally return to its initial state. At this time, the feed chute 36 and the bed surface 20 are separated by the movable plate 322, which can prevent the mineral particles on the bed surface 20 from flowing back.

[0031] Compared with the related art, the utility model provides a shaking table for mineral processing, in which the first enclosure includes a fixed plate and a movable plate. The movable plate is hinged and a rubber baffle is provided at the bottom of the movable plate. The opening size of the discharge port can be automatically adjusted according to the amount of material in the feed chute, adapting to different ore / water inlet speeds, meeting the use requirements under various conditions, and avoiding overflow of ore particles in the feed chute.

[0032] The above describes the embodiments of the present invention in detail, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations to these embodiments without departing from the principles and spirit of the present invention are still within the scope of protection of the present invention.
