Description
Technical field
The present invention relates to agricultural machinery, belongs to the breakthrough improvement of precision drilling machinery structure, particularly a kind of single traction
Adjustable eccentric differential hill planter with suction device.
Background technology
China's agricultural modernization is developed into and is presently used for the mechanical accurate into degree more and more higher of agricultural operation, just must not
It is disconnected as the demand that more advanced agricultural planting is required goes to update, improves the Practical Performance of machinery, country is to soil torsion political affairs
Has there is the farm of many large-scales in the implementation of plan, NORTHWEST CHINA area, and its working area is larger, and the sowing time has
Limit, this just must realize do mechanization operation in each production operation link, and constantly seek the do mechanization operation of high efficient and reliable
Equipment.
In seeding operation link, seeding machinery has pursued the standard of timely, efficient, smart amount, at present, what China adopted
Core component dibbler on plastic film mulch precise hole sowing machinery substantially realizes precision drilling using two kinds of theories of mechanics:1st, it is mechanical
Seed fetching equipment, 2, Pneumatic seed feeding device；Although at present both can reach the requirement of precision drilling, various crops are made
Very poor with, versatility, i.e., a kind of dibbler can only broadcast a kind of or a limited number of kind of crop seed, and its sowing versatility is very poor；Mesh
The aspiration structure used on front market adapts to preferable to the seed of various crops, but to the plant of various crops away from difference will
Asking can not be general, and operating speed bottom, only up to reach 3 kilometers/hour, and this requires that dibbler can broadcast various differences
The crop of size seed, it is desirable to which operating speed is higher, spacing in the rows can be adjusted on a large scale, could only in this way realize a tractor serves several purposes, be risen
To cost-saving synergistic, the stable performance of do mechanization operation, the efficient, purpose of high-quality operation could be preferably played.
The content of the invention
It is an object of the invention to provide a kind of single traction adjustable eccentric differential hill planter with suction device, its simple structure, conjunction
Reason, realization is single to hang traction, can conveniently realize that line-spacing is adjusted on a large scale, realizes that Qu Zhong mechanisms are relative and transports with Artenkreis assembly low speed
OK, it is reliable ensure to take kind, stability, the reliability of seed selection, kind of rate of accuracy reached is taken to more than 98%, while greatly improve making
Industry speed, improves operating efficiency.
The object of the present invention is achieved like this：A kind of single traction adjustable eccentric differential hill planter with suction device, is included in master
