Description

Forced vibration air pressure subsoiling weeding fertilizer applicator
Technical field
The present invention relates to a kind of forced vibration air pressure subsoiling weeding fertilizer applicator.
Background technology
Long-term chemical weed control brings the problems such as weed community transition, herbicide resistance enhancing, environmental pollution, medicament residual and omnicide.Mechanical weeding technology is an important production technology of drought-resistant agriculture sustainable development, be utilize loosen the soil etc. measure prior to seeding, emerge before and the different times such as period of duration carry out weeding, kill except the weeds or grass seed is buried being unearthed, or subterraneous stem is routed up ground be allowed to thirst or freeze to death, thus reach herbicidal effect;Fertilizer can increase crop nutrition content, the nutrition of regulation soil microorganism, improves soil physical chemistry character, finally increases crop yield, and using fertilizer is the important step in agricultural production.Current fertilization mode has and the whole layer placement of fertilizer combined that plows, but fertilizer is readily volatilized in earth's surface and operation process, causes damage, and does not also ensure fertilization effect;Executing seed manure during sowing, it is desirable to seed manure imposes on below seed 5cm, plant side 3~5cm, current fertilizing mechanism structure is more complicated;Foliage dressing, it is desirable to apply liquid fertilizer, but be applicable to large area do mechanization operation;Owing to long-term turns over the shallow-layer tillage methods such as rotary tillage and the use of large farm machinery, soil is compacted, the block that hardens is formed at soil horizon about 30cm, stop moisture penetration, going down to make topsoil to shoal for a long time, soil erosion aggravates, soil degradation, have a strong impact on crop root and go deep into soil layer absorption water and nutrient, and then affect crop yield.
For the problems referred to above, subsoiling weeding fertilizing equipment to improve further farm work performance and quality, reduce labor intensity significant.Subsoiling weeding fertilizing equipment can not only once complete the function such as weeding, fertilising;It addition, subsoiling weeding also has multiple action: can break soil compaction, and then deepen arable layer, soil subsoiling can break ploughing for many years or the hard plough sole of stubble-cleaning formation, increases arable layer thickness;Be conducive to surface water to permeate downwards, reduce rainwash, expand " Soil Reservoir " capacity, not only improve the substantial amounts of rainwater of receiving, may utilize again the water drainage of Mus road;Deep-ploughing implement can improve the utilization rate of land resource, the root system compact district allowing crop moves down, root system residuum increases, condition is provided for microbe survival, humification synthesis is moving phase to reinforcement, and the content of organic matter improves, plays the effect of " foster and apply fertilizer and increase soil fertility ", be conducive to crop root to grow, promote early ripening of the crops high yield.
At present, existing subsoiling facility there is the problem that current soil deep-loosening machine production efficiency is low, wholely, weeding, fertilising operation are separately, tractor repeatedly enter ground will compacting soil, such as working resistance is big present in subsoiling process, the power consumption problem such as too much greatly hinders the popularization of deep-ploughing implement.
Summary of the invention
It is an object of the invention to, for problem above, first the vibrating device that rotates through of tractor motive power output shaft is changed into the vibration of deep soil loosing shovel;It addition, inject air by high-pressure pump to deep soil loosing shovel, both can crush soil with air pressure, air covers on spear simultaneously, forms air film, jointly plays drag reduction effect with vibration;In a word, the invention provides one and can once complete weeding, subsoiling, fertilising operation, and make tilling depth, tilling width and dose size the most adjustable, and the forced vibration air pressure subsoiling weeding fertilizer applicator of energy drag reduction consumption reduction.
It is an object of the invention to be achieved through the following technical solutions:
