Description
Technical field
The present invention relates to agricultural machinery technological field, specifically a kind of rice transplanter accurate fertilizing controls device.
Background technology
Any kind that farmland is used and the chemical fertilizer of form, be impossible to all be absorbed and used by plants.Chemical fertilizer utilizes
Rate, nitrogen is 30 ∽ 60%, and phosphorus is 3 ∽ 25%, and potassium is 30 ∽ 60%.Consumption is excessive, though or use normal, but owing to other are natural or
Artificial origin, can make chemical fertilizer run off in a large number.The nitrogen compound not utilized in time by plant, if can not be adsorbed by soil colloid,
Below the densely distributed level of root system of plant will be transferred to when the soil water permeates downwards and pollute.
The environmental problem that pollution by chemical fertilizer causes mainly has: rivers and creeks, lake, the eutrophication in inland sea.Cause waters eutrophy
The reason changed, mainly in water, nitrogen, the content of phosphorus increase, and make the aquatic plants growths such as algae too much.Soil is contaminated, soil
Physical property deterioration.Long-term excess and use merely chemical fertilizer, soil acidification can be made.Have on soil liquid sweetening of the soil micelle
Machine, the ammonium ion amount of inorganic complex increase, and replace Ca2+, Mg2+ etc., make soil colloid disperse, and Soil structure destroys, soil
Ground hardens, and directly affects agriculture production cost and the yield of crop and quality.In food, feedstuff and drinking water, toxic component increases
Add.The bio-toxicity of nitrite is big 5 ∽ 10 times than nitrate, and nitrite is combined the N-nitroso compound formed with amine
It is then strong carcinogen (see N-nitroso compound and cancer).In the well water in the area of use chemical fertilizer or river, nitrogen compound contains
Amount can increase, even more than drinking water standard.The soil of given too much chemicals can make nitrate in the crop such as vegetable and herbage contain
Amount increases.Food and Nitrite in Feed too high levels, once caused children's and domestic animal intoxication accident.
Possibly together with some other impurity in chemical fertilizer, such as the ∽ 100ppm Han cadmium 1 in rock phosphate in powder, leaded 5 ∽ 10ppm, this
A little impurity also can cause environmental pollution.NO_x in Air Environment content increases.Be applied to the nitrogenous fertilizer in farmland, have a great deal of directly
Evaporate into gas from soil surface, enter air.Quite a few is also had to enter soil with organic or inorganic nitrogen form, at soil
Nitrogen and nitrogen oxides can be changed into from the nitrogen compound of indissoluble state, ADSORPTION STATE and water-soluble state under microbial action, enter air.
Summary of the invention

Fertilising rate signal that control unit transmits, interpolation speed signal, push-button switch signal, display control signal are analyzed and locate
Reason, transmission control signal to DC motor driver, drives direct current generator by DC motor driver, drives conveying worm
Structure controls corresponding dose.
In the present invention: when user is after display control unit sets a dose, and main control unit sends control signal
To DC motor driver, DC motor driver drives direct current generator, dc motor drives spiral conveying mechanism；Fertilising
Velocity sensor sends real-time dose to main control unit, and main control unit, by analyzing and processing, sends control in real time
Signal processed, to DC motor driver, drives direct current generator by DC motor driver, then is controlled spiral shell by direct current generator in real time
Rotation conveying mechanism so that every road dose synchronizes.
In the present invention: button control unit can individually control whether every road fertilizing mechanism works.
In the present invention: when rice transplanter normal operation, fertilization control mechanism regulates voluntarily according to the operating rate of rice transplanter
Dose so that dose keeps certain every time, and can arrange the dose required for this field according to the demand of field.
The operation principle of apparatus of the present invention is described below.
Normal work: needed work at which fertilizing mechanism of button control Unit selection by tractor driver, and in display control
Unit carries the dose that this field needs, it is possible to directly carry out rice transplanting operation.When rice transplanter is in field rice transplanting operation,
Rice transplanter interpolation speed signal at that time is passed to main control unit by interpolation speed sensor.Main control unit is analyzed and processes
Interpolation speed at that time, passes to DC motor driver by the control signal of dose, and DC motor driver drives direct current generator
Driving spiral conveying mechanism, fertilizer passes through fertilizer pipe to spiral conveying mechanism from receptacle, by spiral conveying mechanism by fertilizer
Transferring out, the fertilising velocity sensor on each spiral conveying mechanism sends dose signal at that time to main control list
Unit, the dose data being transmitted through at that time are analyzed and process by main control unit, take the dose data that transmitted at that time
Intermediate value is reference value.Main control unit sends control signal and drives direct current to DC motor driver, DC motor driver
Driven by motor spiral conveying mechanism, the dose controlling each road is identical with reference value.
The good effect that the present invention is had is: the problem that when solving fertilising, yield caused by unevenness of application is uneven.
Solve and cause the problems such as environmental pollution due to improper fertilization.Solve and can carry out different doses according to varying environment
Control, reach treatment in accordance with local conditions.
