Description
Technical field
The present invention relates to the technical field of agricultural planting apparatus, specially a kind of corn double-ridge ditch paving with casing mechanism
Film seeder.
Background technology
The geographical feature in China farmland shows：Hills area accounts for 69%, and Plain only accounts for 31%, and west area generally existing is few
The practical situations such as rain, arid.Fill to collect rain, section, significantly to keep ground moisture and keep ground temperature, existing in order to make full use of
There are arable land limited resources, improve crop yield, film-mulching technique has popularized application in an all-round way.Traditional artificial film mulching method work
Work amount is big, and operation sequence is complicated, wastes time and energy.Friend peasant carries out film-covering planting in the urgent need to overlay film machinery using laminating machine
It is necessity and the development trend of agricultural production.
In recent years, seeding corn and other crops mulch sowing technology is widelyd popularize in arid area, achieves good economic benefit.With
The popularization of ridging mulch sowing technology, related new outfitting tool constantly puts into production application.Mainly have 30 HP Powers with
Ridging laminating machine of the lower tractor with small four wheels as power, this kind of equipment can meet each of the full mulch sowing operation of Semen Maydiss ridging
Item operation, plays the purpose that ground is received in water saving.But, as the difference of agronomy is planted in different regions, cause the adaptability of equipment not
Actual demand can be met.Representative is the current full film double-furrow seeding machinary that widely applies, and the machine is primarily adapted for use in
China Middle Eastern rain-fed agriculture region or slope area corn planting, it is impossible to meet the Ridged plant need of Hexi Irrigation Area field corn
Will.There is a problem of that planting agronomy difference is mainly manifested in：Existing equipment is mainly high about with the wide ridge and ridge of the high about 10cm in ridge
The narrow ridge of 15cm is alternate, and in bottom of trench maize planting, is suitable for the plantation of slope area.And this mode is not suitable with Hexi Irrigation Area land for growing field crops jade
The plantation of rice, one is that ridge is relatively low, easilys lead to flood irrigation and water wasting during irrigation；Two is that soil fertility is poor when ridge bottom is planted,
Corn yield is low.And the Semen Maydiss earthing planting after plastic covered device for using at present, its earthing structure are more complicated, and its rise
Soil is not broken, and there is very big soil block, so causes the soil block overlayed on mulch film not to be compacted mulch film, or even pokes ground
Film, destroys the soil moisture conservation effect of mulch film, reduces corn yield.Therefore for the problems referred to above we have developed one kind can be by soil block
Broken, it is compacted mulch film, it is ensured that the Semen Maydiss earthing planting after plastic covered device of mulch film soil moisture conservation effect and increase corn yield.
Content of the invention
The purpose of the present invention is for above-described problems of the prior art, there is provided soil block can be broken by one kind
