four diversion mechanisms 11 are arranged below the first conical plate 12, and as the driving shaft sleeve 9 is fixedly connected with the connecting rod 15, the connecting rod 15 is rotationally connected with the connecting column 17, and the connecting column 17 is fixedly connected with the diversion plate 18, the diversion plate 18 revolves along the driving shaft sleeve 9 and rotates; as the slurry flows down the first conical plate 12, the deflector 18 will further disrupt the slurry and prevent it from forming a vortex; while allowing large particle impurities in the slurry to fall more easily onto the second conical plate 13.
After the pulp is disturbed by the deflector 18, larger impurities in the pulp can sink onto the second conical plate 13, then fall into a cavity below the second conical plate 13 along the driving shaft sleeve 9 from the middle part of the second conical plate 13, the rest pulp flows into the buffer chamber 6 through the inflow groove 8 and flows into a free sedimentation zone in the concentration tank from the outflow groove 7 at the bottom of the buffer chamber 6, and the flow distribution plate 27 on the outflow groove 7 can uniformly spread the pulp to the periphery to prevent the pulp from flowing out from one direction only, so that vortex is easy to form and the sedimentation effect is influenced.
The bottom of the shell 1 is conical, so that large particle impurities flowing into the lower part of the second conical plate 13 can be gathered to the bottom edge of the driving shaft sleeve 9, a poking piece 20 is correspondingly arranged below the scraping piece 23, the scraping piece 23 and the poking piece 20 are driven to rotate when the driving shaft sleeve 9 rotates, the poking piece 20 pokes a third gear 21 to enable the third gear 21 to rotate, the third gear 21 pushes a rack 22 along the horizontal direction, the rack 22 drives a sliding plate 24 to move, a reset spring 25 is extruded, an outflow opening 28 is opened, the scraping piece 23 is positioned above the outflow opening 28 at the moment, the large particle impurities are poked into the outflow opening 28, and are discharged into a deposition area of a concentration tank, the large particle impurities in ore pulp are prevented from being discharged into a free sedimentation area, the sinking speed of the large particle impurities is high, and the particles which are being precipitated in other areas are disturbed through an interference sedimentation area, a compression area and a deposition area are disturbed when sinking, so that the whole sedimentation effect is influenced. Because the scraping blade 23 and the poking piece 20 are fixedly connected with the driving shaft sleeve 9, the rotating speeds of the scraping blade 23 and the poking piece 20 are the same as those of the driving shaft 2 and the harrow frame, when the outflow opening 28 is opened, the flow speed of the large-particle impurities flowing out of the outflow opening 28 is close to that of the deposition area, and therefore the influence of the large-particle impurities on the impurities of the deposition area is reduced.

one side that the egress opening (28) is close to the transfer sleeve (9) has seted up mounting groove (19), be equipped with rack (22) in mounting groove (19), one side and sliding plate (24) fixed connection of rack (22) toothless board, one side that rack (22) is close to transfer sleeve (9) is equipped with third gear (21), third gear (21) and rack (22) meshing, and third gear (21) are through round pin axle and casing (1) bottom swivelling joint, be equipped with plectrum (20) between third gear (21) and the transfer sleeve (9), plectrum (20) and transfer sleeve (9) fixed connection, and plectrum (20) and third gear (21) cooperation.
2. A method of operating a high efficiency flow stabilization bucket with a flow diversion mechanism as defined in claim 1, comprising the steps of:
step one: the ore pulp enters the shell (1) through the feed pipe (5), firstly, the ore pulp is blocked and decelerated through the spiral guide plate (10), the baffle plate (3) arranged on the upper portion of the spiral guide plate (10), when the ore pulp flows along the spiral guide plate (10), the ore pulp is also subjected to resistance of the fan blades (4), the fan blades (4) are fixedly connected with the transmission shaft sleeve (9), the transmission shaft sleeve (9) is fixedly connected with the transmission shaft (2), the rotating speed of the transmission shaft (2) is slow, and therefore the rotating speed of the fan blades (4) is also reduced, and the fan blades (4) further decelerate the ore pulp; when the fan blades (4) rotate, the edges of the fan blades (4) stir the driving bevel gear (31), the driving bevel gear (31) drives the driven bevel gear (32) to drive the rotating shaft (29) to rotate, and the rotating shaft (29) drives the cleaning rod (30) to rotate, so that vertical grooves on the baffle plate (3) are cleaned;
step two: the guide plate (18) below the first conical plate (12) not only revolves around the transmission shaft sleeve (9) but also rotates; the deflector (18) further disrupts the slurry as it flows down the first conical plate (12); after the pulp is disturbed by the deflector (18), large particle impurities in the pulp sink onto the second conical plate (13), then fall into a cavity below the second conical plate (13) along the transmission shaft sleeve (9) from the middle part of the second conical plate (13), and the rest pulp flows into the buffer chamber (6) through the inflow groove (8) and then flows into a free sedimentation zone in the concentration tank from the outflow groove (7) at the bottom of the buffer chamber (6);
step three: large particle impurities flowing into the lower part of the second conical plate (13) are gathered to the bottom edge of the transmission shaft sleeve (9), the transmission shaft sleeve (9) drives the scraping blade (23) and the poking piece (20) to rotate, the poking piece (20) pokes the third gear (21), the third gear (21) pushes the rack (22) to drive the sliding plate (24) to move, the outflow opening (28) is opened, at the moment, the scraping blade (23) is positioned above the outflow opening (28), and the large particle impurities are poked into the outflow opening (28) to be discharged into a deposition area of the concentration tank.
