Description

Technical Field

[0001] The utility model relates to the technical field of rotary tillers, in particular to an agricultural rotary tiller. Background Art

[0002] A rotary tiller is an agricultural machine used for farming. It is mainly used to till the soil for land preparation before sowing or planting. Compared with traditional plowing, the working principle and effect of the rotary tiller are significantly different. The rotary tiller is an important part of modern agricultural mechanization. Its use has greatly improved farming efficiency, reduced labor costs, and promoted the sustainable development of agriculture.

[0003] A rotary tiller breaks up the soil through a set of rotating blades or teeth, breaking up soil clumps into fine particles and mixing residues and weeds on the soil surface into the soil. Its working part, the rotating blade shaft, is usually driven by the tractor's power output shaft (PTO), and the high-speed rotating blades penetrate deep into the soil to cut, stir and mix.

[0004] Although the rotary tillers in the prior art meet the use requirements to a certain extent, it is found in actual use that the rotary tillers cannot flatten and compact the land after rotary tillage. The uncompacted soil is too loose, which may cause the soil moisture to evaporate too quickly, which is not conducive to seed germination and seedling growth. The soil structure may also become unstable, affecting the development of crop roots. Utility Model Content

[0007] Preferably, the leveling mechanism comprises a first mounting frame, the first mounting frame is rotatably mounted on one side of the main mechanism, a mounting shaft is rotatably mounted inside the first mounting frame, and a grid cylinder is fixedly mounted on an outer wall of the mounting shaft.

[0008] Preferably, the outer wall of the stopper is provided with anti-slip grooves.

[0010] Preferably, the main body mechanism comprises a mounting shell, a knife shaft is rotatably mounted inside the mounting shell, and a plurality of blades are fixedly mounted on the outer wall of the knife shaft.

[0011] Preferably, a reducer is fixedly mounted on the top of the mounting shell, and a connecting frame is fixedly mounted on the top of the mounting shell.

[0012] Preferably, a spike rake is rotatably mounted on one side of the mounting shell.

[0013] Compared with the prior art, the utility model has the following beneficial effects: it is used for agricultural rotary tillers;

[0014] 1. Through the cooperation between the first mounting frame, the mounting shaft and the grid cylinder, the land after the main mechanism is rotary tilled is compacted. In this process, the grid cylinder can better imitate the natural soil compaction process. Through its grid structure in contact with the soil, the soil can be moderately compacted without being over-compacted, and a certain air permeability and drainage of the soil can be maintained without excessive loss of soil moisture;

[0015] In this process, the cooperation among the mounting rod, screw rod, spring and block provides a certain downward pressure for the leveling mechanism, ensuring that the leveling mechanism can effectively compact the land. The compression degree of the spring is changed by rotating the block, thereby changing the downward pressure provided by the downward pressure mechanism for the leveling mechanism, so that the user can flexibly adjust the contact pressure between the leveling mechanism and the ground according to the use requirements.

[0016] The hydraulic cylinder lifts and lowers the leveling mechanism, which makes it easy to change the operation mode of the equipment. The maximum distance of the leveling mechanism is limited by the cooperation between the mounting sleeve, the slide and the connecting rod, ensuring that the grid cylinder always maintains proper contact with the ground, avoiding the loss of its function of compacting and leveling the soil due to excessive lifting or falling of the roller;

[0017] 2. The land is rotary tilled by the knife shaft and blades. The equipment is connected to the tractor through a connecting frame, and the power of the tractor is transmitted to the knife shaft through a reducer. At the same time, the hillocks or pits that may exist after rotary tillage are leveled by a spike harrow to create a more uniform sowing platform, which is conducive to the uniform growth of crops.
