Abstract

The invention discloses an electromechanical-type leveling device of a seedling raising precision planter on farms, and relates to the field of agricultural machinery. The device comprises a PLC (programmable controller), a control switch box, a signal collecting unit, a support leg lifting system, an alarming unit and a horizontal state detecting unit. In leveling, numerical value of a level meter is observed; according to the corresponding leveling method, a servo motor is driven to rotate by the PLC, and further the lifting of the supporting leg is controlled, and the seedling raising precision planter on the farms is leveled accurately. The electromechanical-type leveling device of the seedling raising precision planter on farms has the advantages of simple and convenience in operation, safe and reliable operation, compact structure, rapid and accurate leveling, and capability of improving the working efficiency of the precision planter.

Description

technical field [0001] The invention relates to the technical field of precision seeders for agricultural machinery, in particular to an electromechanical leveling device for field seedling raising precision seeders based on a PLC controller. Background technique [0002] Sowing is an important technical link in the agricultural production process, and the seeder is the core component for realizing mechanized precision sowing. In recent years, the planting area of ​​super rice in my country has continued to expand. Compared with conventional rice, super rice has the advantages of tall plant type, thick stalk, strong power of distributing millet, and large ears and more grains. It is all planted sparsely, which is conducive to the occurrence of millet distributing and the growth of a single plant. Growth, forming a high-yield population structure, with an average of 5,000-7,000 holes planted per mu less than conventional rice. This puts forward a higher standard for sowing an...
