Description

Technical Field

[0001] The utility model relates to the technical field of agricultural machinery, in particular to an automatic soil turning device for corn sowing. Background Art

[0002] 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 my country's main food crop, 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 corn yields.

[0003] For example, the authorization announcement number "CN220368998U" is named an automatic soil-turning device for corn sowing. Although an adjustment component is provided to adjust the angle value of the reclamation plow blade, thereby adjusting and controlling the depth of the reclamation ditch, which greatly increases the practicability of the device and solves the problem of relatively single function, the existing automatic soil-turning device for corn sowing requires that the corn seeds mixed with fertilizer be poured into the storage box in advance, and then the stored corn seeds are guided to be discharged through a drop pipe during the soil-turning and sowing process to achieve the sowing effect. However, a certain number of corn seeds need to be planted in each pit for sowing corn seeds, and there is a lack of a control structure for the discharge of corn seeds in the drop pipe, which makes it difficult to control the discharge amount and speed of corn seeds. Therefore, it is easy for there to be too many or too few seeds in a pit, which affects the sowing effect of the automatic soil-turning device for corn sowing.

[0004] At the same time, the existing automatic soil turning device for corn sowing uses a tillage roller that rotates at the front end to rotate to prepare the soil for planting corn. However, when the soil to be turned is very sticky or has a high water content, the sticky soil is easy to adhere to the gap of the rotating turning component. The adhered soil will fill the gap of the tillage component, causing the subsequent tillage speed to decrease, and the tillage effect will also be affected, thereby reducing the working efficiency of the automatic soil turning device for corn sowing. Utility Model Content

[0005] The utility model aims to solve the problems of poor sowing effect and low working efficiency of the existing automatic soil turning device for corn sowing, and proposes an automatic soil turning device for corn sowing.

The soil-removing plate will reset under the elastic force of the spring sheet and continue to play the role of circulating soil scraping. By automatically cleaning the adhered soil on the soil-turning roller, the working efficiency of the automatic soil-turning device for corn sowing is improved. BRIEF DESCRIPTION OF THE DRAWINGS
