Description
Technical Field
The utility model relates to an agricultural machinery field, concretely relates to straw return shallow-pressing covers strip tiller.
Background
Straw returning is the most key technical link of current agricultural planting, the modern agricultural technology and planting technology can not be used without straw, the protective farming technology comprises straw covering, the common farmers pay attention to the straw problem from the national level, and straw returning covering is the most easily accepted straw returning method by the farmers. The straw is returned to the row, covered and fertilized, the land fertility is improved, the straw is prevented from going to the row, and the straw burning is avoided.
The cultivated land area of northeast region is 4.5 hundred million mu, which accounts for 22.2% of the total cultivated land area in China, the commodity rate of grain is more than 60%, and the method is the biggest commodity grain base of China. However, soil degradation that has continued for many years is threatening the grain production capacity of the northeast commercial bases. Research and production show that unreasonable cultivation is the main cause of soil degradation in northeast, and meanwhile, the cultivation benefits are reduced, and serious environmental problems such as air pollution, sand storm, water system non-point source pollution and the like caused by straw burning are caused. The development of a green high-efficiency cultivation technology systematically solves the production and environmental problems in the northeast region, and has great significance. Therefore, the Chinese academy of sciences aims at the problems that the straws are difficult to leave stubbles at high height, the row spacing is smaller than that of the foreign countries and the wind is more strong in spring when the straws are harvested in the northeast of China at present and the difficulty of straw full-coverage no-tillage popularization is large, and provides a straw return-to-row shallow-pressing covering strip rotary tillage technology. According to the principle of the mutual combination of agricultural machinery and agriculture, and in order to better develop the technology, a novel straw returning shallow-pressing covering strip tiller can be produced at once.
At present, straw row-returning covering no-tillage seeding is to firstly use a preposed line-returning machine to clear and return straw rows twice, then use a no-tillage seeding machine to sow the straw rows in a no-tillage mode in a straw clearing belt, and also use a strip rotary cultivator to carry out rotary tillage on the straw to a soil plough layer and sow the straw. And no matched machine tool is available for straw row-returning shallow-pressing covering strip cultivation.
The existing strip rotary cultivator usually adopts a rotary cultivator side box transmission mode, can effectively avoid strip rotary strip missing cultivation, but due to uneven straw distribution caused by side box dragging, the wide popularization of the technology is severely restricted. Due to the fact that the tractor is often suspended due to the fact that the land is uneven, the straw returning effect is affected, and straw stacking is caused. Narrow rubber wheel can play fine limit dark effect, nevertheless can't reach the problem of the effective suppression of straw, because the strong wind in the spring sowing season of the northeast area of china is more, the straw of returning the line is also often blown away because of the problem of strong wind, leads to the straw to distribute unevenly to influence the crop and emerge, rearmounted single-roller suppression hardly realizes the effect of suppression soil moisture conservation. The prior strip rotary cultivator can not meet the technical requirement of straw row-returning shallow-pressing covering strip cultivation.
The prior authorization notice number of front-mounted corn protective tillage straw sorting machine is as follows: CN 207720650U, as can be seen from figure 1, bullet tooth 18 is installed on finger dish 17, and the inside of finger dish 17 diameter and bullet tooth 18 between be the fretwork state, during operation, the straw is twined on finger dish 17 and bullet tooth 18 after getting into very easily from the fretwork place, leads to the straw not evenly to cover, even makes finger dish 17 unable rotation to influence work efficiency.
The utility model discloses a solve the supporting machines and tools requirement that present straw returned to go and cover the strip farming, at first utilize neotype straw clearance to return to make a transition the mechanism and realize that the straw clearance with evenly return to go, later carry out dark pine and strip rotary tillage in the area of preparing for tillage, the straw shallow pressing that the part soil that splashes in the rotary tillage will return to go is fixed, utilizes simultaneously to prevent that the clay land roller carries out the suppression to rotary tillage area and straw return to go in the area. The agricultural requirement of straw returning shallow-pressing covering strip cultivation is finished at one time.
