Description

Technical Field

[0001] The utility model relates to an agricultural machine, in particular to a strip tillage machine with the function of dispersing moisture and raising temperature of low-lying land. Background Art

[0002] In recent years, the area of ​​corn cultivation using conservation tillage technology has gradually increased in my country, and the technology of returning straw to the field in rows and strip tillage has been continuously accepted by farmers. However, for low-lying plots, due to the high soil moisture content, poor drainage and low ground temperature, the operation of existing strip tillage machines is limited. In particular, the existing strip tillage machines are heavily suppressed, which easily form a hard cover after operation, and cannot effectively disperse moisture and raise temperature, affecting subsequent seedling emergence. The straw return operation in low-lying plots cannot achieve the ideal operation quality, which makes the straw return to the field strip tillage technology in low-lying plots The application is limited. In order to solve the problem of better applying the straw returning to the field strip tillage technology in low-lying plots, the utility model provides a strip tillage machine with the function of dispersing moisture and raising the temperature of low-lying plots. According to the requirements of dispersing moisture and raising the temperature of low-lying plots, a deep loosening shovel with a rat path component is used to form a transparent rat path; deep rotary tillage is used to increase soil ventilation performance; small pear turning shovels are used on both sides of the front to hook out drainage and ventilation ditches; light pressing and the pressing strength of the pressing roller can be easily adjusted to achieve the effect of rapid moisture dissipation. The above technical measures have solved the problem well. Utility Model Content

[0003] The purpose of the utility model is to provide a strip tillage machine with the function of dispersing moisture and raising temperature of low-lying land, so as to solve the problems raised in the above-mentioned background technology.

[0004] In order to solve the above technical problems, the utility model provides the following technical solutions: a strip tillage machine with the function of dispersing moisture and raising temperature in low-lying land includes a frame, a gearbox, a deep tillage shovel, a lower suspension frame, a deep tillage shovel seat, a depth-limiting ground wheel, a depth-limiting ground wheel adjustment screw, a coupling, an upper suspension frame, a pressure roller bracket, a pressure roller adjustment spring, a pressure roller, a soil-covering disc, a soil-covering disc bracket, a side gear box, a strip tillage knife roller, a rotary tillage knife, a small pear turning mounting seat, a left small pear turning, a right small pear turning, an upper adjustment nut, a lower adjustment nut, a depth-limiting ground wheel mounting seat, a pressure roller adjustment hole, a pressure roller adjustment rod, an R-shaped wave pin, an adjustment spring pad, a small pear turning fixing bolt, a ratway component fixing bolt, and a ratway component. It is characterized in that the deep tillage shovel is provided with a ratway component, and a ratway is formed during the deep tillage process, which is conducive to the infiltration of rainwater and forms a ventilated and breathable structure.

[0005] It is further described that a left small pear flipper and a right small pear flipper are arranged at the ends of the corresponding strip tillage knife rollers on both sides of the deep tillage shovel. During operation, the left small pear flipper turns the soil and a small amount of straw to the left, and the right small pear flipper turns the soil and a small amount of straw to the right, so that two clean ventilation grooves are formed in the strip tillage seedling belt, which is beneficial to the moisture dispersion and temperature increase of the seedling belt.

[0006] Further, by adjusting the depth-limiting ground wheel adjustment screw, the depth-limiting ground wheel is raised, so that the strip-tillage knife roller of the strip-tillage machine is relatively lowered, and the strip-tillage depth is increased to 25 cm, so that the deep soil layer is permeable, and the purpose of quickly dissipating moisture and raising temperature is achieved.

[0007] The further described pressing roller has no driving device, and the rotation speed is completely controlled by the operating speed of the tractor. Thus, the pressing strength of the pressing roller is much smaller than that of the existing driven pressing roller, forming a soil structure that is loose on the top and solid on the bottom, which is beneficial to moisture dispersion and temperature increase.

[0008] The pressing strength of the pressing roller is further adjusted by the pressing roller adjusting spring. When the latch of the pressing spring is adjusted upward, the downward force on the pressing roller is reduced, and the pressing strength is weakened, which is beneficial to moisture dissipation and temperature increase.
