Land leveling system for paddy field rotary cultivator

Abstract

The invention discloses a land leveling system for a paddy field rotary cultivator. The land leveling system comprises a left-side pull rod, a middle pull rod, a right-side pull rod, a land leveling unit, a driving unit, a hydraulic operation mechanism and a controller, wherein the hydraulic operation mechanism is used for manipulating the land leveling unit; the controller is used for controlling the hydraulic operation mechanism. The land leveling system for the paddy field rotary cultivator has the advantages that a land leveling device with an automatic leveling function is additionally arranged on a rotary cultivator according to agronomic requirements of rice cultivation, so that a land leveling plate is positioned in a horizontal plane all the time in the cultivating and land-leveling processes, therefore the influence to the land leveling device from a tractor due to different mud foot depths and own vibration during a proceeding process is reduced, and the land leveling precision is further improved. The land leveling system for the paddy field rotary cultivator can be used with the existing paddy field rotary cultivator for performing rotary cultivation and soil preparation on paddy fields in a matching manner, so that the land leveling effect of the paddy field rotary cultivator is improved; meanwhile in comparison with a paddy field laser land leveler, the land leveling system for the paddy field rotary cultivator has the advantages of low cost and convenience in popularization and application.

Description

technical field [0001] The invention relates to the technical field of agricultural machinery, in particular to a paddy field rotary tiller leveling system. Background technique [0002] In rice mechanized production, plowing and preparation is an important link. The quality of plowing and preparation directly affects the effect of rice sowing and other follow-up operations of rice production. The flatness of the soil must meet the agronomic requirements. According to the requirements of rice planting, the difference in field height between rice planting and transplanting should not be greater than 3cm, and the unevenness of the land is too large, so that after the field is irrigated, part of the soil will not be submerged in water, and the area exposed to the water cannot be effectively closed for weeding. The field is flat, but the fertilizer is spread evenly, improving fertilizer efficiency, reducing the use of chemical fertilizers and pesticides, reducing pollution to th...

Problems solved by technology

The impact of field tillage operations on field leveling accuracy is mainly due to the constant changes in the walking depth of the tractor wheels in the field, causing the tillage machinery to shake from side to side and back and forth; secondly, the vibration of the tillage machinery itself makes the flat floor vibrate, which affects the field. leveling accuracy

[0003] For existing tillage and leveling machines, such as the utility model patent application number 200820041185.0, a straw returning machine is disclosed. After the rotary tillage and stubble removal, the grass can be pressed and leveled by the grass leveling mechanism behind the machine, ensuring The straw is buried in the cultivated land, but the leveling mechanism is connected with the frame, and the position cannot be adjusted. Its own vibration will affect the offset of the leveling mechanism in the horizontal plane, and the leveling accuracy is limited.

For example, the utility model patent with application number 200820066760.0 discloses a suspended multi-purpose farmland plowing operation machine, which uses a tension spring damper and a split pressure roller, which can be adapted to the plowing operations between the seedlings of the farmland and the entire width of the machine. The roller is leveled by the profiling principle, and the spring damper will vibrate during the adjustment process, which will affect the effect of profiling leveling

[0004] At present, there are mainly two types of tillage and leveling machines, profiling and laser leveling. Among them, the traditional leveling technology is profiling, such as roller harrow, disc harrow, toothed harrow, compactor, etc., with poor controllability and mechanical inclination. All will lead to poor leveling effect, so it is difficult to meet the leveling agronomic requirements; although the application of laser leveling technology in agricultural production can improve the accuracy of leveling, but due to the high cost of laser leveling machines and the large number of equipment, it is not suitable for popularization and use.

At present, most of the plowing and leveling machines popularized and applied in our country have problems such as complex structure, high price, poor operation effect, low utilization rate of machines and tools, and poor economic benefits.
