Description

Self-priming self-vibration self-skating type rice screener

The utility model relates to a kind of self-priming self-vibration self-skating type rice screener, belongs to agricultural product processing machinery.

Present rural area rice milling machinery, in husk rice, the cavings that shells when only removing husk rice can't be removed stone, the stalk of sneaking in the paddy, crack rice.Paddy is adding the friction that is subjected to machinery man-hour, and the temperature of rice raises, as untimely cooling, and the warehouse of just can not packing into, otherwise rice can be rotten.In order to lower the temperature, the rice of peasant after processing be deposited on the place or the bag of packing in be put on the vacant lot and lower the temperature naturally.But crushed stone, grass in the rice, crack rice and part chaff shell, just must blow with hand sieve or electric fan and raise, do like this and take a lot of work, require great effort, the manual simultaneously precision of screening is not high.

The purpose of this utility model is exactly in order to overcome the deficiencies in the prior art, a kind of self-priming self-vibration self-skating type rice screener is provided, it utilizes mechanical oscillation principle and aerodynamic principle, can dock the rice screener that screens and lower the temperature with rice mill in husk rice.

Above-mentioned purpose is achieved in that self-priming self-vibration self-skating type rice screener, comprise elevating hopper, separator box, charging hopper, Seperating box, sieve box and collection powder device, elevating hopper is connected with feeding tube with separator box, a downward-sloping skimming baffle is welded in the separator box porch, the breach of skimming baffle is positioned at separator box outlet top, the heavy center of gravity automatic valve of the hinged end assembling in exit, the separator box port of export places charging hopper central authorities, and the hole of its side top is connected with exhaust duct with the blower fan axis hole.The awl mouth of charging hopper is connected with bolt with the Seperating box upper end, controls inlet amount with plate.The top welding of Seperating box is skewed flow deflector, one side has several vents, respective side is uniformly-spaced welded the end and is skewed disengaging pawl, the disengaging pawl right side is an air inlet, air inlet is connected with airduct with elevating hopper, intake is controlled with plate in air inlet and airduct junction, the heavy center of gravity automatic valve of the hinged end assembling of its port of export downward vertically, be stalk, chaff shell outlet herein, the baffle plate on its air inlet place, top welding band inclined-plane, the baffle plate breach is positioned at the discharging opening top, and feeding tube and airduct are fixed with anchor ear and support.The collection powder is connected with bolt with support with blower fan from device, and the exhaust outlet of blower fan is connected with collection powder device charging aperture.Be connected with Seperating box by sieving the sieve box that sheet forms up and down, the sieve box is fixed by bolts on the support.The horizontal segment of top sieve sheet is opened a groove downwards, and the end of groove links to each other with the stone outlet of sieve on the box, and the lower end of following sieve sheet is the polished rice outlet, and the outlet of cracking rice is positioned at down sieves below the sheet.Under sieve sheet and connect sieve sheet adjustable plate with bolt near the Seperating box place, established angle α=38 of upper and lower sieve sheet °, β=42 °, following sieve sheet is finer and closely woven than the sieve aperture of top sieve sheet.For increasing dust-exhausting quantity, can increase a blower fan again, be connected with air inlet on the Seperating box, replace airduct with it.

This self-priming self-vibration self-skating type rice screener, novel in design, be skillfully constructed, its elevating hopper is docked with the rice mill outlet, open fan switch, just can screen through rice screener grinding good rice, polished rice inserts the pocket from the polished rice outlet, crack rice and stone flows out from separately outlet, crack rice and can make liquor-making raw material or make feed, rice bran is then collected by collection powder device.The polished rice uniform particles that this machine is separated is clean, has guaranteed the quality of rice, has also alleviated peasant's labour intensity greatly.
