Description
Technical Field
The invention belongs to the technical field of agricultural machinery, and particularly relates to a tray covering and supplying machine for rice industrialized pot seedling raising and a tray covering method thereof.
Background
The rice planting industry in China is well developed, but the mechanization of rice planting is laggard behind, the planting becomes the weakest link in the mechanization in the whole process of rice production, and the mechanized seeding and seedling raising technology of rice is the core of the mechanization of rice planting. A precision seeding assembly line for raising rice seedlings by rice seedling trays is main equipment for raising rice seedlings in factories and comprises key processes of feeding the rice seedling trays, paving bottom soil, compacting, seeding, covering surface soil, sprinkling water, stacking the trays and the like. At the present stage of China, the research on related equipment for industrial rice seedling raising is weak, the research on soil sowing, sowing and water spraying parts is mature, but key technologies need to be broken through. At present, the industrialized rice pot seedling in China mainly adopts a plastic uptake soft plug tray, and the precision seeding of 2 +/-1 grains per plug is carried out on the plastic uptake plug tray by a seeding streamline, and then the plastic uptake plug tray is sent into a darkroom for seedling. In order to save space, the trays are often stacked for seedling. However, the common plastic trays have soft texture, dense holes and large size deviation, and can not realize stacking seedling raising, so the soft trays are usually sleeved into hard trays to realize stacking seedling raising. In the process of tray sleeving, soft hole trays are generally separated manually and then sleeved into hard trays one by one, so that the production cost is increased, the labor intensity is higher, and the production efficiency of industrial seedling raising is severely restricted. Therefore, in order to avoid the complex work of supplying trays one by workers, reduce the labor intensity and improve the operation efficiency of the rice seedling raising and sowing assembly line, the automatic tray supplying device, the tray sleeving device and the related control system of the rice seedling raising and sowing assembly line with reliable performance, high efficiency and practicability are urgently needed to be researched.
Various precision seeding production lines for raising rice seedling trays at home and abroad are available, and automatic tray supply devices are designed and developed on part of production lines. For example, the precision vegetable sowing production line developed by the Holland Visser company is provided with an automatic seedling hole tray arranging machine, a square plastic foam seedling tray is used, and the working efficiency of the whole machine reaches 1250 trays/h. An indoor complete set of rice seedling raising production line with complete facilities, high efficiency and high automation degree is developed by Nisshini Mitsubishi and Mitsubishi, and the efficiency of an automatic tray supply device mechanism is more than 1000 trays/h, wherein the automatic tray supply device mechanism is precise and complex (comprising various modes such as a spiral mode, a guide rod mode, a swing arm mode and the like). But because of high price, the method is only introduced in a few large-scale seedling raising companies in China and is not widely applied at present. The full-automatic seedling raising production line manufactured by Jiangsu Yunmai Co Ltd in China comprises an automatic tray feeding machine, has the advantages of small size, light weight and quick tray feeding speed, but can only be used with a seedling tray of the company; the Taiwan lucky enterprise company Limited in China aims at the fact that the automatic rice seedling tray feeding device manufactured by traditional blanket seedling raising is high in speed, high in efficiency and expensive. By analyzing the present situation and the structural characteristics of the automatic seedling tray supply device at home and abroad, the machine type can realize automatic seedling tray supply, and the productivity of different devices is different. The conventional seedling tray feeding device mainly adopts the principle of combining pneumatics and machines to carry out tray feeding operation, most of devices are complex in structure, not only are the cost high, but also the maintenance cost is high, and therefore, the design of a simple automatic tray feeding machine is very necessary.
