Embodiment
Below by drawings and Examples the technical solution of the utility model is described in further detail.
As shown in Figure 1, 2, this shaking table feeding device, the stir shaft that it comprises feed bin, supports the supporting leg of feed bin and be arranged on feed bin inside, feed bin is made up of tubular storehouse 4 and back taper storehouse 7, and feed bin is supported by four supporting legs 15, and the supporting leg bottom is welded with base plate 11; Feed bin top is tubular, the bottom is a back taper, the feed bin center upper portion is equipped with a back up pad 3, cycloidal planetary gear speed reducer 1 is fastened on back up pad 3 tops by bolt 2, the output shaft of cycloidal planetary gear speed reducer 1 passes the hole that offers on the back up pad 3 and is connected with stir shaft 5 by shaft coupling 16, and shaft coupling is a flange-face coupling, and the bottom inside of the reverse taper portion of feed bin is fixed with inclined clapboard, the discharge port of feed bin bottom is connected with discharge nozzle 12, and the discharge nozzle exit is provided with butterfly valve; Stir shaft 5 is provided with agitating vane 6, and the stir shaft bottom is equipped with screw-blade 8; One deflector chute 9 tilts to be connected with discharge nozzle 12, and the deflector chute front end is downward-sloping, and the deflector chute ingress is provided with the limit flitch; The reverse taper portion bottom of feed bin is provided with top wash tub pipe 14, and ball valve 13 is installed in the wash tub pipe of top, is provided with bottom wash tub pipe 10 in the discharge nozzle, and top wash tub pipe, bottom wash tub pipe connect the shaking table water feeding system.
Material enters the feed bin from the opening for feed on feed bin top, the output shaft of cycloidal planetary gear speed reducer 1 drives stir shaft 5 rotations by shaft coupling 16, agitating vane 6 on the stir shaft is broken up material, and material moves downward under the rotary thrust effect of gravity and stir shaft and enters discharge nozzle 12; The bottom inside fixed inclined clapboard of the reverse taper portion of feed bin can prevent that material from following agitating vane and rotating together, simultaneously material is imported the discharge nozzle inlet; The screw-blade 8 that is arranged in discharge nozzle is with stir shaft 5 rotations, and the screw-blade of rotation evenly is delivered to discharge nozzle 12 outlets with material, the butterfly valve control material blanking velocity in discharge nozzle exit; The water diluted material of top wash tub pipe 14 ejections prevents that material from stopping up the feed bin discharge port, and the water diluted material that bottom wash tub pipe 10 upwards ejects prevents that simultaneously material from stopping up water outlet; Material after diluted enters deflector chute by the limit flitch of deflector chute 9 ingress, imports in the shaking table feeding trough through deflector chute again, finishes a mass transport to shaking table.
Because the upper and lower part wash tub pipe makes material loosening to the flushing and the diluting effect of material, strengthen of the break up effect of shaking table water feeding system to material, strengthen shaking table tossing effect, the tiny diamond that can not shake out before the shaking table is shaken out.
When material is during than the heavy-gravity plaster material, the speed of rotation of the stir shaft that speeds up by regulating cycloidal planetary gear speed reducer, increase the aquifer yield of top wash tub pipe by the pressure that increases ball valve in the wash tub pipe of top, strengthen the butterfly valve opening in discharge nozzle exit, material is evenly fallen, satisfy the requirement of shaking table feed.
When material is rarer, reduce the speed of rotation of stir shaft by the speed of regulating cycloidal planetary gear speed reducer, reduce the aquifer yield of top wash tub pipe by the pressure that reduces ball valve in the wash tub pipe of top, reduce the butterfly valve opening in discharge nozzle exit, control material falling velocity.
When rarer and water content is big when material, be prone to the solid-liquid separation state, diamantiferous material can sink rapidly, blocks the discharge port of feed bin rapidly, causes material to descend slowly, occurs stagnating blanking when serious, and perhaps material descends inhomogeneous; When above-mentioned situation occurring, make the cycloidal planetary gear speed reducer reverse rotation, the pressure of regulating ball valve increases the aquifer yield of top wash tub pipe, reduces the butterfly valve opening in discharge nozzle exit, regulates the limit flitch of deflector chute ingress, can reach the purpose of even feeding.
