Description
Technical field
The present invention relates to seed coating technology, particularly a kind ofly can measure seed feed quantity and realize kind of liquid and work in coordination with the seed pelleting machine of accurately supply and plant medicine and work in coordination with On-line Control device and method by dynamic weighing online.
Background technology
Along with agricultural product processing machinery equipment is to intelligent direction development, all kinds of seed pelleting machine is also developing to Efficient intelligent.Judge that one of standard of a seed-coating machine quality is dressing qualification rate.The influence factor of seed pelleting qualification rate comprises the mixed ratio of seed and seed coat agent, seed mixes order of contact etc. with the mixture of seed coat agent, wherein the mixed ratio of seed and seed coat agent is the most important thing that seed-coating machine controls, and accomplishes accurately to control with regard to need of coating machine feeding and hello liquid precise coordination.
At present, what most of seed-coating machine adopted feeds liquid mode is extract seed coat agent by the measuring pump of driven by motor to realize, after seed coat agent enters compounding chamber, through being atomized and planting grain mixture.The control of motors of metering pumps adopts Frequency Converter Control substantially, and control accuracy is very high, thus, ensures kind of a key factor for liquid mix ratio is exactly how to measure feeder to feed the quality of planting.
Existing seed-coating machine drawing-in device major part is adopted in two ways.
The first arm bar bucket type feeder, this is traditional feeding manner, feeder is made up of two tipping buckets, after one of them is filled, compounding chamber is entered because leverage principle makes feeder swing shed kind of a grain, another tipping bucket moves to feed opening and accesses kind of a grain, such reciprocating simultaneously, constantly feeds the kind grain waiting to want dressing.The feeding Mass Calculation mode of this kind of method is: the unit weight of seed is multiplied by container volume and gets the weight that often struggles against.Due to lever principle, the power that tipping bucket motion critical point tipping bucket bears is fixing, the feeding weight in this way recorded is accurate substantially, but the shortcoming that tipping bucket feeding exists is that feeding does not have continuity, often have the time interval between bucket kind of grain, and now measuring pump hello liquid is continual, so just can not ensure the mix ratio of kind of liquid, and production efficiency is on the low side.
The second is impeller type feeder, this feeder is made up of impeller and motor, blade on impeller is equally distributed, there is a space being similar to bucket type between every sheet blade, by surrounding package mechanism, upper and lower for impeller two parts are kept apart, when driven by motor wheel rotation, kind of a grain is filled in bucket type space above impeller, along with rotation, plant grain and be brought into lower end, shed and enter in compounding chamber.This kind of method calculates the product of coefficient of fullness three parameters of the interior seed of unit weight, bucket type spatial volume and bucket that the mode of feeding kind of quality is seed.This feeder achieves the requirement of continuous blanking, but to load the degree of filling of seed different in bucket type space when rotated due to impeller, and calculate quality according to fixing coefficient of fullness, accuracy can not be guaranteed.

On-Line Control Method flow chart worked in coordination with by the kind medicine being one embodiment of the invention see Fig. 5, Fig. 5.On-Line Control Method worked in coordination with by the kind medicine of seed pelleting machine of the present invention, above-mentioned kind medicine is adopted to work in coordination with On-line Control device 4, on-line dynamic measurement seed feed quantity realizes with the mixed ratio accurately controlling seed and seed coat agent that kind of liquid is collaborative to be supplied, and specifically comprises the steps:
Step S100, Real-time Collection seed weight information, the seed flowed out the blanking device 2 of seed pelleting machine carries out real-time online and weighs and the weight information exporting described seed;
Step S200, calculating control liquid quantity delivered, carry out data processing to described weight information, and calculate according to the kind liquid mixed ratio of setting and control the quantity delivered of liquid needed for described seed;
Step S300, liquid supply, according to the liquid of described quantity delivered toward conveying corresponding amount in the compounding chamber 3 of described seed pelleting machine.
Wherein, in described step S100, also comprise:
Set the sense cycle t that weighs, the seeds fall flowed out to make described blanking device 2 keeps continuity.Can under the prerequisite of blanking device 2 constant rotational speed, arrange one shed arm 413 shed interval as the sense cycle t that weighs, playing can seed in accumulation pallet prevent the effect that seed is overflowed by weighing pan.In order to the continuity ensureing to feed kind, the time interval of at every turn the shedding sense cycle t that namely weighs should be less than the compounding time of kind of grain in compounding chamber 3, before the seed mixture of a collection of measurement completes namely, treats that mixture seed will fall to the weighing tray 412 of compounding chamber 3.This sense cycle t that weighs ranges preferably from kind of grain is fallen to weighing tray 412 time by blanking device 2, when namely mixture seed starts mixture, treats that mixture seed preparation falls.Setting glassware 2 to the distance of weighing tray 412 is h, can obtain t, namely according to freely falling body formula
In described step S100, the computing formula of the weight information of described seed is preferably:
G
t＝(g
1+g
2)*c，
