Description

Pascal's gear train tobacco pot seedling transplanting and water injection joint operation mechanism

technical field

The invention belongs to agricultural machinery, and mainly relates to a transplanting and water injection operation mechanism for tobacco pot seedlings in dry fields.

Background technique

Tobacco planting in my country takes seedling raising and transplanting as the main planting mode. The traditional tobacco planting mode is mainly based on manual labor, which is not only labor-intensive and low-efficiency, but also difficult to guarantee the planting quality of tobacco seedlings. Therefore, the automation and mechanization of tobacco transplanting is the development direction of tobacco planting mode. The automatic transplanting of tobacco pot seedlings is a complicated process, which needs to realize the continuous operation of taking seedlings, conveying and planting actions of tobacco pot seedlings, that is, to complete three actions with one set of mechanisms. At present, most of the transplanting machines suitable for tobacco pot seedlings on the foreign market use single-chip microcomputers, air valves, and manipulators to realize the automatic planting of tobacco seedlings. Although they can meet the agronomic requirements of tobacco planting, the highly integrated control technology makes transplanting difficult. The structure of the machine is very complicated, the system is huge, and the cost is high, which is difficult for Chinese farmers to accept. Most of the domestic tobacco special transplanting machines are a combination of simple mechanisms, and multiple mechanisms are used to complete the seedling taking, transportation and planting of tobacco pot seedling transplantation, which is inefficient. And the models that can inject water synchronously after tobacco transplanting are still relatively few, and the quality of water injection operation is poor.

Contents of the invention

The purpose of the present invention is to provide a Pascal gear system tobacco seedling transplanting and water injection joint operation mechanism that can meet the agronomic requirements of tobacco pot seedling transplanting, and realize continuous transplantation of tobacco pot seedlings in the actions of taking seedlings, transporting and planting. At the same time as the planting operation, in order to cooperate with the field operation of tobacco transplanting and facilitate management, the transplanted tobacco seedlings are injected with water synchronously, so as to avoid the phenomenon of tobacco withering caused by water shortage during long-term field transplanting operations, and achieve the combined operation of transplanting and water injection , The purpose of simplifying the structure of the machine tool, reducing the manufacturing cost of the machine tool, improving the working efficiency and ensuring the working quality.

The purpose of the present invention is achieved in this way: the Pascal non-circular sun gear is fixed on the frame assembly, the planet carrier is rotatably installed on the frame assembly, the Pascal non-circular intermediate wheel and the Pascal non-circular planetary gear are rotatable The Pascal non-circular intermediate gear meshes with the Pascal non-circular sun gear and the Pascal non-circular planetary gear respectively to form a non-constant speed Pascal planetary gear train. The Pascal non-circular planetary gear and the Pascal non-circular planetary gear The sun gear is the same, the transplanting arm is fixed on the Pascal non-circular planetary gear, and the first sprocket is fixed on the planet carrier; Inner pipe body, a fan-shaped water outlet hole is set on the side wall of the cylindrical inner pipe body, the cylindrical outer shell with the second sprocket fixed can be rotatably fitted on the outside of the cylindrical inner pipe body, and the water outlet pipe is fixed in the cylindrical On the outer casing of the tubular type, the outlet pipe is connected or closed to the fan-shaped water outlet hole on the inner tube body of the cylindrical type; the transmission chain is set on the first sprocket and the second sprocket, thus forming a Pascal gear system. Planting and water injection joint operation mechanism.

The invention applies the Pascal gear planetary system to the fully automatic transplanting mechanism for tobacco pot seedlings, and uses a set of mechanisms to complete the continuous actions of picking, transporting and planting tobacco pot seedlings, which greatly simplifies the tobacco pot seedling transplanting mechanism. Tobacco transplanting is completed by using the Pascal gear planetary system and the transplanting arm, which can achieve the characteristics of compact structure, small vibration, stable transmission, high operating efficiency, reliable use, and few failures. The running trajectory of the transplanting arm meets and adapts To meet the agronomic requirements of taking, sending and planting tobacco pot seedlings, the tobacco seedlings are injected with water synchronously through the rotary intermittent water injection mechanism, which avoids the phenomenon of tobacco seedlings withering due to failure to replenish water in time during long-term field transplanting operations. It has the characteristics of greatly simplified mechanism structure, high operation efficiency, good operation quality and low cost.
