Description
Technical field
The present invention relates to a kind of eccentric circle disc type broadcast application and sower, specifically a kind ofly spread fertilizer over the fields fertilizer and broadcast sowing the high-efficiency precision amount broadcast application sower of crop seed for floods and droughts field.
Background technology
Often, artificially applying fertilizer and sowing workload are large, occupied a large amount of agricultural workforces, and efficiency are low for the fertilising operation of the crop growth such as paddy rice, wheat phase, and labour intensity is large, and human body directly contacts with chemical fertilizer, also can affect healthy.Artificial broadcast application sowing, spreads fertilizer over the fields inequality, and chemical fertilizer easily excessively uses, and causes environmental pollution, makes soil compaction, reduces soil quality.And mechanization essence amount ferti-seeding, efficiency significantly improves, and broadcasts sowing evenly, and the amount of spreading fertilizer over the fields is controlled, reduces loss of chemical fertilizer and volatilization, reduces crop seed waste, and conservation of nature ecotope better, realizes agriculture sustainable development.
Domestic and international existing eccentric circle disc type broadcast application seeding technique and machinery, as the two disk fertilizer distributors of MDS series of Hua Lian, Beijing mechanical & electrical technology equipment company production, scientific and technological achievement " the two disk fertilizer distributors of 2FH-12 that Zhao Shuying etc. complete, Chinese patent " two disk centrifugal type fertilizer spreader " (CN2696296), Chinese patent " fertile amount adjustable fertilizer distributor " (CN201905031U) etc., general supporting farm tractor three point linkage connects, fertilizer in fertile case or crop seed under Action of Gravity Field by dropping under defertilizing opening on the broadcast application disk of rotation, under centrifugal action, shed out, have simple in structure, easy to operate, weight is lighter, broadcast sowing the features such as wider range, be applicable to spreading fertilizer over the fields graininess, powdered fertilizer, but there is following weak point:
1) the broadcast application dish of broadcast application device is generally designed to the single fixed form of diameter, the adjusting of broadcast application fabric width mainly relies on broadcast application dish rotation speed change to realize, and broadcast application rotation speed change is limited in scope, the adjustable range of broadcast application fabric width is little, is not suitable with the job requirement of continuous high-efficient broadcast application.
2) general supporting farm tractor operation, installs location once broadcast application facility articulate, and the working depth of broadcast application dish and fertile case is difficult to regulate, and can not adapt to the larger floods and droughts field working condition of physical features height fluctuations.
3) when fertiliser granulates viscosity or humidity are when larger, fertiliser granulates is easily reunited, and relies on merely material gravity effect to be not enough to overcome resistance, causes material to stop up and blocks up in fertile case bottom, can not fall by continous-stable.
4) stir fertile device general with broadcast application dish coaxial rotation, speed adjustable range is limited, in the time that speed is higher, impact is excessive, fertiliser granulates is broken meticulous, causes fertilizer atomization to drift about, and loses larger.
5) stir fertile device and broadcast application device and adopt mechanical speed change, velocity variations scope is little, and can not regulate continuously, is difficult to adapt to different fertilizer and crop seed stirring and smart variable and broadcasts sowing job requirement.
Thereby, need at present broadcast application seeding machinery, the especially one of the staple crops such as a kind of applicable paddy rice, wheat to be applicable to spread fertilizer over the fields graininess, Powdered fertilizer, also can broadcast sowing the high-efficiency precision amount broadcast application sower of crop seed.
