Description
Technical field
The present invention relates to fertilizing equipment technical fields, and in particular to the synchronous fertilizer applicator of rice transplanting.
Background technique
Fertilizing method when traditional rice transplanting is directly by broadcast application, and fertilizer is volatile or outflows with water, and causes
Fertilizer waste, also pollutes the environment into the chemical fertilizer ingredient in river and air.Fertilizer can be reduced in such a way that trench digging is applied deeply
Fertilizer efficiency is concentrated in material waste, to reduce rate of fertilizer.Side deep fertilizing is synchronized while rice transplanting to be realized
Rice transplanting, the primary completion of fertilising.The synchronous side deep fertilizing of rice transplanting, which refers to, equably applies fertilizer concentration while rice transplanting
Fertilization mode in certain depth soil.The synchronous fertilising of rice transplanting is disposably completed fertilising while rice transplanting and is made
Industry eliminates artificial broadcast application link, considerably reduces labor intensity, saved labor cost.
Deep application of fertilizer also helps the absorption of rice growing season fertilizer, can promote root growth and development, can extend fertilizer efficiency, improves
Utilization rate of fertilizer guarantees the supply of rice growing season especially Later growth nutrient.The advantage that fertilizer is concentrated is: fertilizer and soil
Contact is few, and the concentration of fertilizer of fertilizer placement is high, and microorganism obtains less, and denitrogenation is few, and the fertilizer that can be utilized by rice absorbing is more, utilizes
Rate is high.
But in rice transplanting, equipment is in hot, high humidity environment, and fertiliser granulates surface humidity is melted, flowing
Property be deteriorated.In addition rainy weather is such as encountered during fertilising equally causes fertiliser granulates surface moist, poor fluidity.
Poor fluidity later just needs the longer gravity time to guarantee that moist fertiliser granulates take off from roller
From, and existing fertilizer applicator is all to do circular motion at the uniform velocity, time of the collected manure slot of roller really towards underface is very short,
Moist fertilizer cannot completely disengage collected manure slot, and fertilization effect is poor.
In addition: being disclosed in my unit patent of invention of Patent No. " 201820743328.6 " " a kind of for paddy field
Molding ditch deep fertilizer spraying covering device ", plough carries out upper downward by the way of upward-downward translation, with lead screw mode
Section, entire stress is all on lead screw, and the upper end of lead screw is fixed in kickboard, and the stress of kickboard junction is bigger,
It is very easy to damage.
Another problem that exist is that in operation in above-mentioned patented product actual application, fertiliser granulates pass through wind
The air-flow of machine assists conveying in the duct.That is, fertiliser granulates are blown in fertile ditch by air-flow in former,
The mixture of fertiliser granulates and air-flow in ditch have certain speed, the soil of usual mud ditch inner surface be all it is wet viscous,
Fertiliser granulates can largely adhere to furrow bank under the impact force of air-flow, but since strength is bigger, also some fertilizer
Particle can by disturbance of the air-flow in ditch (it has been generally acknowledged that: strength is quickly blown out from pipeline, after encountering bottom of trench and furrow bank, air-flow
Can circle round upwards, the air-flow in ditch is the chaotic state of disturbance) it takes to outside furrow bank middle and upper part or ditch, cause the concentration of fertilizer
It is bad to apply effect deeply.The more satisfactory method of application of fertilizer is: concentrating on bottom of trench position, depth is reasonable.As fruit part fertilizer is applied
It is unfavorable to being absorbed and utilized for this part fertilizer to ditch middle and upper part or to outside ditch.In addition, if fertiliser granulates are not concentrated, with soil
Earth and microorganism contact are more, and fertilizer element is easily absorbed by the micro-organisms, and the nutrient being absorbed by crops can be reduced temporarily.
Although above-mentioned patent discloses trailing bar, but the poor fluidity of common trailing bar soil in earthing, especially
It is in paddy field in use, the position that cannot preferably make the soil on ditch both sides flow to fertile ditch fills mud ditch, earthing effect
Difference.
