Duck-billed soil opener opening and closing control mechanism for corn planter

Abstract

The invention provides a duck-billed soil opener opening and closing control mechanism for a corn planter. The duck-billed soil opener opening and closing control mechanism comprises a lower torsion spring, an upper torsion spring, an upper retaining block, a sliding groove, a steel wire rope, a supporting rod, a seed case, a seed case projection, a T-shaped block, a lower retaining block and a V-shaped block. The control mechanism is characterized in that an upper clamping spring and a lower clamping spring are fixed on the inner wall of the seed case, the T-shaped block and the V-shaped block are hinged on the inner wall of the seed case, the upper retaining block is fixed on the upper left corner of the T-shaped block, the lower retaining block is fixed on the right side of the V-shaped block, the sliding groove is formed in the seed case, and the steel wire rope penetrates the sliding groove. According to the duck-billed soil opener opening and closing control mechanism for the corn planter, original easy wearing portion is changed into the standard steel wire rope, parts and components are more durable and simple and convenient to obtain and replace, rapid maintenance and replacement can be achieved when the easy wearing portion is damaged in the corn planting process, replacement time is shortened, and the mechanism is simple, convenient to open and close, and planting quality is improved.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to an opening and closing control mechanism of a duckbill type cavitation device for a corn planter. Background technique [0002] Corn is a typical row crop suitable for precision sowing. It is also the dryland crop with the largest planting area in my country. It is one of the important food and feed crops and industrial raw materials in China. The rational promotion and application of corn precision seeding machinery has become the key to increasing corn production and income. The development of corn mechanized planting in plain areas is relatively fast, with more suitable machinery and a high level of development; the development of corn mechanized planting in hilly areas is obviously backward, with fewer suitable machines and a lower level, which is far behind plain areas, and regional development is unbalanced increasingly prominent. Due to factors such as ec...
