detailed description of the invention
Below in conjunction with accompanying drawing, a kind of medicine winnowing machine of the present utility model is described further.
As Fig. 1, shown in Fig. 2, the medicine winnowing machine of the present embodiment, comprise frame 1, be located at the pay-off 2 in frame 1 and pneumatic separation device 3, frame 1 is provided with a control cabinet 11, pay-off 2 and pneumatic separation device 3 are controlled by control cabinet 11, pay-off 2 comprises upper strata vibration feeding disc 21, lower floor's vibration feeding disc 22 and vibrating device 23, vibrating device 23 vibrates with lower floor vibration feeding disc 22 and is connected, upper strata vibration feeding disc 21 is fixedly connected with by support bar with lower floor vibration feeding disc 22, pneumatic separation device 3 comprises little winnowing machine 31, large winnowing machine 32, be located at air outlet 33 and the selection by winnowing motor 34 at winnowing machine top, upper strata vibration feeding disc 21 is located at the air inlet of little winnowing machine 31, lower floor's vibration feeding disc 22 extends the air inlet being located at large winnowing machine 32, the below of large winnowing machine 32 air inlet is oblique is provided with lower floor's discharge bucket 35, the discharging opening of little winnowing machine 31 is provided with one and littlely sweeps leaf device 36, the discharging opening of large winnowing machine 32 is provided with one and sweeps greatly leaf device 37, little below of sweeping leaf device 36 is laterally provided with a upper strata discharging conveying 38, sweep greatly discharge bucket 39 after being provided with below leaf device 37, selection by winnowing motor 34 is frequency control motor.
During operation, because selection by winnowing motor is frequency control, the setting of wind speed therefore can be carried out according to the demand of medicine.First set on the controller the wind speed of winnowing machine, then medicine is placed in the vibration feeding disc of upper strata, starting drive.Start the vibration of after vibration device, drive upper strata vibrating disk vibration, the air port place of little winnowing machine delivered to equably by medicine on the vibrating disk of upper strata by vibration, the foreign matters such as the powder in material, feather, the end of a thread are inhaled into little winnowing machine, the impurity such as the floating thing of lightweight is discharged through air outlet, slightly heavy feather fall into upper strata discharging and carry through little leaf device of sweeping and be delivered to refuse collecting case; Material heavier after selection by winnowing falls in lower floor's vibration feeding disc, the air port place delivering to large winnowing machine is equably continued through vibration, heavy material such as glass, stone, shell etc. fall into lower floor's discharge bucket, lighter dust to be inhaled in large winnowing machine and to discharge through air outlet, and the material of last high-quality falls into rear discharge bucket collect from the leaf device of sweeping greatly of large winnowing machine.
In the present embodiment, upper strata vibration feeding disc 21 is provided with adjustment doors I 12 with the junction, air port of little winnowing machine 31, and lower floor's vibration feeding disc 22 is provided with adjustment doors II 13 with the junction, air port of large winnowing machine 32.The adjustment doors I of upper strata vibration feeding disc tail end can be used for the wind-force and the material thickness that control little winnowing machine, the adjustment doors II of lower floor's vibration feeding disc 22 tail end can control strong wind and select the wind-force of machine and the thickness of lower floor's material, to prevent that mass transport is blocked up or wind-force is excessive and to affect selection by winnowing effect.
In the present embodiment, little sweep leaf device 36 and sweep greatly leaf device 37 driven by motor 14 by belt pulley.By same driven by motor, little winnowing machine and large winnowing machine step can be made to be consistent, to also reduce the energy consumption of equipment simultaneously.The utility model is screened by secondary and carries out selection by winnowing separation to material successively, and technique is advanced and sub-material is effective.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; be understood that; the foregoing is only specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any amendment made, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
