Description

Technical Field

[0001] The invention belongs to agricultural machinery, and in particular relates to a rice greenhouse seedling raising tray lifting and collecting integrated machine. Background Art

[0002] Rice is the grain crop with the largest planting area, the highest yield per unit area, and the largest total output in my country. It is China's largest grain crop and plays a pivotal role in my country's grain production. In the entire process of rice seedling production, early seedling cultivation is an important link, and among the various production steps of rice cultivation, the tray-lifting step is one of the important basic steps. When lifting the tray, the focus of protecting the seedling tray is the integrity of the seedling tray and the seedling. If the breakage rate is too high, it will cause a reduction in production and reduce economic benefits. Manual lifting of rice seedling trays has low production efficiency, high labor costs, and high labor intensity. The seedling trays are easily broken during repeated operations, which affects the transplanting rate of the seedlings. In order to realize the mechanization of removing rice seedling trays, improve operation efficiency, save costs and reduce labor intensity, a rice seedling tray removing machine is used to replace the original manual tray removing method to realize the mechanized operation of removing rice seedling trays, which has become a development trend of the modern rice full-process production model. For example, the public document with publication number CN110521357A discloses a rice seedling tray removing machine. Although it solves the problem of manual tray removal, it does not have a matching mechanism for separating the seedlings and the seedling tray, and collecting the seedlings. It still needs manual separation of the seedlings and the seedling tray, and collection of the seedlings, which cannot free people from a lot of labor and does not fundamentally solve the problems of high labor intensity, low operation efficiency, high labor demand, high cost and high seedling breakage rate.
