Duplex type dressing machine of the present utility model, can be used for cleaning wheat class, corn, soybean, also for cleaning rapeseed, paddy rice, white melon seeds, red bean etc., have the advantages that grain, seed selection, classification, grain feelings clearly detect and judge a tractor serves several purposes such as Class of food crop, just clear through the machine the moisture content of newly gathering in the crops can be safe storage moisture content time, can meet the technological requirement of oven dry, after being dried, can make clearly again clean grain reach commodity food optimal level standard through the machine.
Duplex type dressing machine of the present utility model, can be used for the clear grain operations of unit such as state farm, grain trade warehouse, grain depot and seed selection operation, also can be used for seed processing factory purification of seeds etc., so the machine is to have to improve the ideal clear grain grain grading judgement machinery of grain quality increase commodity rate.
Duplex type dressing machine of the present utility model, uses operating process to comprise following step.
1, the inspection of state of the art; The integrity of inspection machine, changes, repairs the part that damages or be out of shape in time, firm each several part loose bolts, comprehensively lubricated each oil site.
2, select work-yard; The machine is suitable for indoor and outdoor and cleans operation, and the place gradient should not exceed the adjusting range of machine.The machine, as supported the use at indoor and drying equipment, should, according to production line technological process requirement, be laid down road wheel, redesigns fixed mechanism.
3, machine is fixing; Machine enters place and answers reasonable arrangement feeding and net export position, and before and after putting well, both sides screw mandrel is very heavy, adjusts vertical and horizontal level, otherwise, the crooked operation of machine, load is uneven, will affect clear grain effect.
4, test running; Before driving, must accomplish:
(1) check blower fan rotation direction: main frame should be by machine mark direction rotation.
(2) check whether the each parts of complete machine are installed correctly.
(3) each portion bolt should be firm.
(4) move driving pulley with hand, see and have or not running obstacle.
(5) install belt hood, carry out the test running of idling lotus, after each portion works well, can carry out grain operation clearly.
5, select screen cloth (screening washer); Screen cloth specification is very large for screening quality influence, should be according to different grain variety, and the strict screening network planning lattice of selecting.
The selection principle of screen cloth specification is as follows:
(1) top sieve: sieve aperture should guarantee that large mixing all screened out, and better seed can all pass through.General soybean: φ 8.5, wheat, 4.0; 4.5.Corn: φ 12, vegetable seed φ 2.0.
(2) sieve in: better seed can all pass through.General soybean: 5.5, wheat 3.0, corn 4.5, vegetable seed 1.6.
(3) lower sieve: sieve aperture should guarantee that complete seed stays on compass screen surface, general soybean 4.0; Wheat 2.0, corn 4.0, vegetable seed 1.2-1.3.
(4) the screen cloth specification of work screen cloth: the screen size of seed selection is than the large 0.1mm(finger widths of sample screen size or diameter), the screen size that clear grain is used is sieved the large 0.2mm-0.3mm of screen size than sample.
Should note: in the time selecting sieve aperture specification, clear grain should be grasped flexibly according to the quality requirement of commodity food.When seed selection, should require to propose required screen cloth specification and quantity by user according to the cleanliness of seed, messenger's letter be processed and all can.
6, the adjustment of machine
(1) adjustment of machine and Gravity Separation platform: according to cleaning grain variety, by supporting intake mechanism (screw feeder) by the ability of cleaning of the machine unit interval, cereal is evenly delivered to feeding mouth and (feed screw feeder by adjustment, the flow that feeding mouth two is exported is even) assorted remaining baffle plate is in the closed position, according to table top separation case, adjust at any time assorted remaining height of baffle plate.Depending on cereal in table top cross direction profiles situation, by adjusting screw with leading screw is very heavy adjusts.
Table top is containing confused flour beetle thing exit thickness 60-80mm, and remaining exit thickness 30-4mm mixes.In half suspended state, separating effect is better.Should be according to cereal unit weight, containing assorted moisture flexible modulation each portion air door and separating table face tilt elevation angle angle, until clearly demarcated containing confused flour beetle thing levels, cereal and the counter motion of impurity differential are best for well.
(2) adjustment of each portion air quantity: according to the separation case of Gravity Separation table top blended grain, air-flow plate is adjusted in examination.Should be as the criterion with Gravity Separation table top first half, depending on seeing mixture in table top motion steadily, impurity from cereal, separates fast and backflow is fast, and clean grain output speed is fast, is considered as optimum state.As blended grain is in table top bumpy motion, impurity separates and refluxes not obviously, and clean grain output speed is slow, shows that anterior air quantity is large, should debug air-flow plate, makes unnecessary air quantity flow to Gravity Separation table top rear portion; Though as steady in the motion of Gravity Separation table top mixture, impurity separates poor, cereal output speed is very fast, and this shows that anterior air quantity is less, and air quantity is adjusted in examination.Gravity Separation table top latter half, as too loose on table top in blended grain, table top rear portion blended grain layer thickness is greater than 40 millimeters, cereal output speed is slow, and assorted remaining separation is poor, has the table top of leakage phenomenon, this shows that backstage face portion air quantity is less, should close air quantity adjustment doors.By the Correctly adjust of air-flow plate and air quantity adjustment doors, make the separation of table top blended grain keep optimum state for well.
7, the movement of machinery; In the machine when design, has adopted light-duty frame, its running gear to be only applicable to move in threshing ground field; And aerated rubber tyre before and after having installed, so that traction is transported for long-distance.
8, grain feelings are online detects by display terminal, the information such as show grain moisture content, go mouldy, and judge Class of food crop.
