Abstract
A double-cylinder cleaning sieve belongs to oil grain cleaning equipment and is characterized in that an inner sieve cylinder and an outer sieve cylinder are horizontally and coaxially arranged in a rack, inner sieve holes are larger than outer sieve holes, spiral conveying belts are arranged on the inner walls of the inner sieve cylinder and the outer sieve cylinder, the cross section of the outer sieve cylinder is a regular polygon with 6-16 sides, one end of the inner sieve cylinder and one end of the outer sieve cylinder are connected with a transmission shaft through a flexible coupling, the coupling adopts a gear-inserting type connecting disc, polyurethane blocks are filled between teeth, and a large impurity outlet, a raw grain outlet and a small impurity outlet are arranged below the rack. The utility model is used for the clearance of former grain such as corn, wheat, maize, soybean, vegetable seed can get rid of great debris and less debris simultaneously, and compact, take up an area of fewly, with low costs, production efficiency is high, excellent in use effect.
Description
Technical field
The utility model relates to a kind of cylinder cleaning sieve that is used for removing raw grain impurity.
Background technology
Contain the various impurity that differ in size in the raw grains such as paddy, wheat, corn, soybean, vegetable seed, must remove before the processing, generally adopt the cylinder cleaning to screen out assorted.Existing cylinder cleaning sieve has only a screen drum or two screen drums arranged side by side, can only remove bigger foreign material in the rolling, and often adapted rotary flat sieve or vibratory cleaning sieve removes less foreign material again.So both strengthen investment, improved cost, accounted for the place more again, also had influence on production efficiency.
The utility model content
The technical problems to be solved in the utility model is the weak point that overcomes existing cylinder cleaning sieve, provides a kind of and can remove simultaneously in the raw grain than bigger material and less foreign material, and the bitubular that volume is little, cost is low, production efficiency is high, result of use is good cleaning sieve.
The technical solution of the utility model is: bitubular cleaning sieve comprises frame, screen drum, transmission mechanism, to be described screen drums be made of the inside and outside screen drum of the coaxial setting of level improvements, interior screen drum sieve aperture is greater than outer screen drum sieve aperture, inside and outside inboard wall of riddle drum all has spiral conveyor, one end of inside and outside screen drum power transmission shaft common and in the transmission mechanism is connected, the other end of inside and outside screen drum is that the discharge end below is respectively equipped with big assorted outlet and the raw grain outlet that is fixed on the frame, and outer screen drum cylindrical shell below is provided with the little assorted outlet that is fixed on the frame.
Further scheme is: outer screen drum cross section is the regular polygon on 6～16 limits; One end of inside and outside screen drum is connected with power transmission shaft by flexible clutch jointly; Described flexible clutch is made of left and right terminal pad and polyurethane block, and the rectangular teeth of left and right terminal pad inserts mutually, and polyurethane block is contained in the gap of rectangular teeth; Outer screen drum discharge end is provided with support ring, and this support ring places on the carrying roller.
During the utility model work, inside and outside screen drum rotates simultaneously, the raw grain of screen drum and foreign material roll with screen drum in feeding hopper enters, wherein stay in the interior screen drum than bigger material, enter big assorted outlet along spiral conveyor, and raw grain and less foreign material pass in the screen drum sieve aperture enter in the outer screen drum, wherein less foreign material further pass outer screen drum sieve aperture and fall into little assorted outlet, and raw grain is left in the outer screen drum, enters the raw grain outlet along spiral conveyor.Like this, the utility model can be removed big assorted and little the mixing in the raw grain simultaneously, and compared with the cylinder cleaning sieve adapted rotary flat sieve of original use or the impurity removing equipment of vibratory cleaning sieve, obviously volume is little, and cost is low, and saves time, the production efficiency height.In the utility model, outer screen drum cross section is a regular polygon, makes raw grain produce the gap in rolling and beats, and is difficult for stopping up sieve aperture; Inside and outside screen drum is connected with power transmission shaft by flexible clutch, and outer screen drum discharge end is placed on the carrying roller by support ring, vibration or stuck phenomenon in the equipment operation that can avoid causing because of the same axis error of screen drum and power transmission shaft and screen drum deadweight and raw grain weight, improve stationarity, reliability, result of use is good.Flexible clutch preferably adopts the terminal pad of band rectangular teeth, and between cog is equipped with polyurethane block, makes simply installation, easy to maintenance, effective.
