Description

TECHNICAL FIELD

[0001] The utility model relates to cotton film laying planting technical field, concretely is a kind of split type profiling soil roller. BACKGROUND

[0002] Cotton film laying planting technology is widely applied in northwest region of China, and mulching film covering technology can effectively improve the growth conditions of crops under film, and also can inhibit the damage of weeds and pests to crops, so that the yield of crops is multiplied, and the income of farmers is greatly improved, with the development of mulching film cultivation technology, higher requirements are put forward to the working performance of film sowing machine, and soil roller is the main working component of film sowing machine, and the parameter optimization has great influence on seeding quality;At the same time, because there is often wind and sand in northwest region, so generally soil covering device is needed to prevent mulching film from being scraped, and soil roller takes soil to the roller through side round sheet, so as to make the gap between rollers leak soil and cover on the surface of mulching film, and because of the reason of terrain undulation, there is a large gap under mulching film, which will seriously affect the seeding and hole forming effect of hole seeder, so profiling soil roller needs to be used to play the effect of pressing, thereby guaranteeing the film laying seeding quality.

[0003] Soil roller device has been used for a long time with the development of seeding machine, and soil covering operation is an important link in the process of cotton seeding, which needs to meet the requirements of cotton mechanized precision hole seeding technology, xinjiang planting mode and agronomy, in order to ensure the quality of soil covering, uniformity and soil pressing effect are also important factors of precision seeding;Therefore, seeding machine soil pressing device should meet the requirements of cotton seed covering area and soil thickness, and the operation effect should reach the degree of uniform and dense soil covering, so as to increase the emergence rate of cotton seed, therefore, the operation performance of soil pressing device is closely related to the growth, distribution uniformity of cotton seed after seeding and cotton yield, although most types of cotton seeding machines on the market can realize soil pressing and other functions, but the soil pressing device only has functionality, and finally the operation effect is uneven, the soil thickness is difficult to control, the soil uniformity is poor, and it is excessively dependent on the debugging experience of farmers, which consumes manpower and material resources and affects the consistency of seeding depth.

[0004] The existing covering roller is mostly shaftless, the inner walls of the grading rollers are connected through spokes, the grading rollers are combined into one body, and cannot be graded and profiled, and when the ground surface is large in relief, the film laying quality is reduced. The operation modes of the existing covering and compacting device are mainly divided into three modes, the first mode is the separation of covering and compacting operations, in the mode, the traction of the tractor is used as the driving force, the covering and compacting device is connected with the seeding device, the soil is transported or extruded to the seed row through the mechanical mechanism, and then the compacting wheel is used for compacting, so as to achieve the purpose of covering and compacting, the second mode is the device for only covering without compacting, which is similar to the first mode in the covering operation process, but the compacting device is not arranged, and the soil is relied on the weight of the soil to compact the crop seeds, the third mode is the integration of covering and compacting operations, in the mode, the covering and compacting device usually adopts the structure of the double compacting wheel with an angle, and can complete the extrusion and accumulation of the soil and the compacting operation, and compared with the three covering and compacting modes, and in combination with the wide film covering and the drip irrigation and seeding mode under the film of the cotton planting, the second mode is usually selected as the covering and compacting mode, and the existing covering roller can meet the use of the second mode.

[0005] However, the existing covering roller still has many problems in the use process: firstly, the grading single body of the covering roller does not have a local profiling effect, and if the ground surface is slightly high and low in relief, a large number of gaps exist under the mulching film, which greatly affects the film laying quality and the compacting effect, reduces the hole forming effect of the hole seeder, and affects the seeding quality, and secondly, since the rollers are connected into one body through spokes, when the soil leakage is uneven, the adjusting groove is located in the interior of the roller, and the adjusting roller is inconvenient to adjust, therefore, a separate profiling covering roller is urgently needed to solve the above problems.
