Description
Affiliated technical field
This is suitable for novel a kind of plant protection mechanism that relates to, and refers to air suction typed locust killing machine especially.
Background technology
Locust cries locust again, is a kind of harmful insect, kind surplus China has 300 approximately, be distributed widely in all parts of the country, stem, leaf with each plant species are food, and be particularly serious to the harm of crops and herbage, once broke out for several times the large-scale plague of locusts in Ancient Times in China and modern times, often can be gathered into huge colonies tens million of and even several hundred million and carry out the long-distance apprentice of moving, cover all the sky in the place of arrival, a thousand of barren land, complete devastation of land, people feel simply helpless.Can only adopt manual catching and killing or chicken, duck and flying bird to peck in the past, but produce little effect, at present people have adopted the method for medical treatment and the biological control locust of going out again, the secondary pollution that medical treatment causes, serious to environmental destruction, unsuitable large tracts of land is used and is promoted, and biological control needs a large amount of funds and the input of human and material resources, the control cycle is grown, produces effects slow, is difficult to resolve the matter of great urgency, so the locust of going out is still the difficult problem in the China and even the world.
Summary of the invention
Novel a kind of air suction typed locust killing machine that provides is provided for this, this machine can with the supporting use of tractor with small four wheels, and utilize tractor engine to be used as power, the airflow that produces when adopting the centrifugal fan rotation, flow is about 1.7-2.0m
3/ S, flow velocity is equivalent to strong wind more than 9 grades up to 24m/S, is far longer than the flotation velocity of locust, will suck in the air channel and is blown into cutter mill attached to the locust on the face of land and the plant stem, sheds on the ground by sieve screen apertures after shredding.Tractor constantly advances, and blower fan and cutter mill turn round continuously, and locust is then eliminated in large quantities.
This technical scheme that is suitable for novel its technical barrier of solution is: air suction typed locust killing machine can be articulated in Dongfanghong-170, on the front beam of 180P or 200P type tractor, utilize engine (S1100, ZH1115 type single cylinder diesel) is used as power, the V belt transmission, behind Clutch Control and double reduction, driving blower fan and cutter mill turns round simultaneously, rotating speed is 1200rpm, blower fan is that centrifugal flexible variable is apart from blade and medium-pressure type, and adopt radially air intake and radially air discharge structure, air inlet is towards ground, exhaust outlet is connected with the cutter mill charging aperture, the cutter mill discharging opening can all be shed ground after the chopping with the locust and the disconnected stem of weeds that enter in the cutter mill also towards ground and semi-circular gravure screen cloth and blade acting in conjunction be set.
This is suitable for novel beneficial effect: novel structure, install easily, and easy and simple to handle, the deinsectization that can generally be adapted to vast farming district and the pastoral area locust operation of going out, working width is 1.6m, and pace is 4-6km/h (the low II-IV retaining of tractor), and productivity ratio is 0.6-0.95hm
2/ h (can finish the locust area 90-140 mu that goes out every day), operating cost is about 10-15 unit/hm
2, and ecotope do not had any pollution and destruction, be easy to widespread adoption and promote.
