Description

A kind of floods and droughts dual-purpose rotary tillage broadcast application sower

Technical field

The utility model relates to a kind of agricultural machinery, particularly a kind of floods and droughts dual-purpose rotary tillage broadcast application sower.

Background technology

The hand of current China drags owning amount to be more than ten times of large and middle tractor, it is the tillage implement of peasant's indispensability that the hand of more than 90% drags, hand drags and can realize glebe straw returning rotary tillage, broadcast application, the multiple working of sowing and paddy field straw-returning stubble-burying rotary tillage, fertilizing and seeding apparatus is arranged on hand and drags above arm-rest frame by the patent No. 201010257695.3 glebe straw returning combined seed and fertilizer drill, the seed mouth that falls of sowing pipe is arranged on the top of pressure stubble cage, along with grinding constantly bringing forth new ideas of examination, the method of sowing pipe above pressure stubble cage is not suitable for the sowing demand staying high stubble field, stay the stalk of high stubble about 400mm under fence stops, hack after rotary tillage flies out quantity not sufficient, in pressure stubble cage, hack amount is few, seed covers rate variance, Shortcomings.Current paddy field basal dressing is still by manually carrying out, peasant carries more than 20 kilogram of chemical fertilizer one one being sprinkling upon field, as the fertilizer of two kinds of heterogeneities need be spread, must walk twice in mud field, very arduous, tiring, effect is low, the Chain conveyer part broadcasting sowing mechanism of prior art is not set up defences guard shield, operation is often by stalk, earth clamping is stuck, fragile chain, more can not descend paddy-field-working, the rotary cultivator tail wheel dish diameter also having current hand to drag paddy-field-working to use is less than 440mm, during paddy-field-working, tail wheel diameter is less than normal, tail-wheel fork is caused to bury to scrape band stalk serious, affect operation and bury a batch effect, supporting rotary tillage broadcast application sower is dragged also not reach the requirement of paddy field returning straw into field and rotary cultivation and fertilising with hand, existing defects.

Summary of the invention

The purpose of this utility model is the deficiency for staying high stubble straw-returning and paddy field returning straw into field and rotary cultivation and fertilising, there is provided a kind of structure simple, multiple seed and granular fertilizer can be broadcasted sowing, seed and granular fertilizer are sown in tool roller axis front, can the operation of dry land rotary tillage ferti-seeding, again can paddy field returning straw into field and rotary cultivation the floods and droughts dual-purpose rotary tillage broadcast application sower of two kinds of heterogeneity granular fertilizers can be spread fertilizer over the fields.

Scheme of the present utility model is: a kind of floods and droughts dual-purpose rotary tillage broadcast application sower, the sprocket wheel comprising rotovator and broadcast application seeding apparatus and install on the driving shaft, chain and protective cover, by support bar, broadcast application seeding apparatus being fixed on hand drags above chassis, broadcast sowing the front that pipe is arranged on rotavator knife roll shaft, fertilizer and seed are sown on the earth's surface of the non-rotary tillage in tool roller axis front, the diameter of tail wheel dish is made 440-550mm, during paddy-field-working, tail-wheel fork does not bury, the stalk imbedded under earth's surface can not be scraped band and be unearthed table by installing sprocket wheel on the driving shaft, chain-driving broadcast application seeder rotation operation, sprocket wheel is on the driving shaft installed and chain is easily arranged protective cover by the position that stalk earth twines folder and water inlet, bury a batch roller arranging one between rotavator knife roll shaft and tail wheel dish, by batch tooth bar that buries buried on batch roller, stalk is buried in the lower 30-50mm of soil table.

The utility model has the advantages that: 1. broadcast application seeding apparatus is fixed on hand and drags above chassis, unit center of gravity is suitable for, meet the plantation demand staying high stubble straw-returning, can be used as the broadcast application sowing of the multiple kinds of crops such as corn, soybean, paddy and wheat, parts need not be changed, by the adjustment amount of broadcasting sowing to different crops.2. broadcast application seeder driving member arranges protective cover, substantially increase service life, and paddy field can be descended to use, realize the demand that hand drags rotary tillage limit, limit, paddy field broadcast application.3. strengthen tail wheel diameter, tail-wheel fork height unearthed table during paddy-field-working, the stalk imbedded under soil table can not be scraped the unearthed table of band, substantially increase effect, reduce power consumption, bury stubble effective.
