Description
Technical Field
The utility model belongs to the technical field of agricultural machine, especially, relate to a strip straw is smashed and is close a line machine of doing things, specifically speaking can realize that the strip straw is smashed under whole straw covers the earth's surface condition to smash the straw and go back the line operation, belong to the straw strip and smash the machinery of integrative operation of going back.
Background
Corn is the first major food crop in Liaoning province and plays an important role in stabilizing national food safety. However, the Liaoning corn planting area generally has the problems of uneven rainfall distribution, frequent occurrence of seasonal drought mainly due to spring drought, low water storage and retention capacity caused by soil plough layer structural obstacle and the like. The straw mulching no-tillage planting technology is widely concerned due to the advantages of corrosion prevention, soil moisture preservation and stable yield of cultivated soil, and the key for realizing large-scale, mechanized and light-simplified no-tillage planting lies in the treatment of straws. Wind frequently is high in spring seasons in Liaoning areas, the straws are smashed while the corn is harvested mechanically, building piles are easily formed under the action of wind force, seeding operation of spring agricultural machinery is further influenced, the whole straw covers the corn straws, the corn straws can be stabilized, nearly half of power of the corn harvester can be saved (power output of the agricultural machinery is saved by closing the power of returning the corn harvester to the field), the corrosion prevention and soil moisture preservation effects and the cost saving effects of the whole straw covers are more remarkable, and moreover, a northeast black land protective farming action plan (2020-2025 years) printed in this year is clearly pointed out, and a tillage-free and less-farming technical mode taking the straw covers as the core is mainly popularized. The whole straw coverage of the straws can become a core technical mode in protective cultivation in the semiarid area in the North Liaoning province. The efficient no-tillage seeding machine in production has a seedling belt straw cleaning function, but the existing ridge distance in Liaoning province is less than or equal to 60cm, and under the condition that the whole straw is covered and returned to the field in successive years, the seedling belt straw cleaning function of the seeding machine is only relied on, so that the dragging and blocking are easily caused, and the seeding effect is further influenced. The foreign protective farming seeding effect is superior, firstly, the residual quantity of the straws in unit area is smaller than the total straw coverage in the current northeast corn production, secondly, the ridge distance of the planting is more than or equal to 76cm, the straw separation effect is good, and the blockage and the pile dragging can not be caused. According to the practical situations of the current matched power of the seeding machinery, the matched requirement of the corn harvester on the ridge distance, the use right boundary of the household co-production contracted land and the like, the change of the ridge distance is expensive, so that a solution can only be sought in the aspect of straw treatment.
