Description

Technical Field

[0001] The utility model belongs to the technical field of corn sowing, and particularly relates to an automatic soil turning device for corn sowing. Background Art

[0002] Generally, before sowing corn, it is necessary to turn the soil to loosen the soil and remove weeds to provide a good growth environment for the growth of corn. With the improvement of planting and cultivation technology and the popularization of agricultural mechanization, many crops are planted by mechanical operations, which reduces manpower and material resources while also improving the efficiency of production operations. As the main food crop in my country, corn has the characteristics of a wide distribution range and a large planting area. As the main link in corn production, corn sowing technology directly affects the yield of corn.

[0003] At present, when sowing corn, workers usually use soil turning devices to turn the soil and dig furrows to reduce labor intensity. At this time, workers only need to sow. However, the soil turning devices in the prior art still have certain shortcomings. For example, the existing soil turning devices have relatively single functions and can only perform soil turning and furrowing operations. Subsequent sowing and filling and burial still need to be done manually, resulting in low overall sowing efficiency.

[0004] A Chinese patent with publication number "CN220368998U" discloses an automatic soil turning device for corn sowing, which includes a main body, a soil turning component, a furrowing component, a burying component and a sowing component, wherein the device includes two first mounting plates installed on both sides of the lower surface of the main body, and soil turning components installed on the two first mounting plates. The automatic soil turning device for corn sowing can automatically complete the soil turning, furrowing, sowing and soil covering and burying operations required in the corn planting process by setting structures such as soil turning components, furrowing components, burying components and sowing components, greatly improving the corn sowing efficiency and reducing the labor intensity of the staff. At the same time, by setting an adjustment component, the angle value of the reclamation coulter can be adjusted, thereby adjusting and controlling the depth of the reclamation ditch, greatly increasing the practicality of the device and solving the problem of relatively single functions in the prior art.

[0005] Although the above-mentioned device is relatively convenient to use as a whole during use, it still has certain defects and shortcomings in its specific application process. First of all, during its use, the overall height of the plow blade is relatively fixed. When the soil tillage depth needs to be adjusted, it cannot be flexibly adjusted. Its overall adaptability is poor. At the same time, its plow blade is fixedly installed on the outer surface of the linkage rod. During its use, it is extremely cumbersome and inconvenient to replace it. Utility Model Content
