Airflow vibrating type ordered seedling throwing and separating mechanism

Abstract

The invention discloses a pneumatic-vibratory device for ordered rice transplanting and separating, which comprises a vibrating-mechanism driving vibrating conveying board which is mounted in the frame by flat spring, the surface for potted seedling feeding of the vibrating conveying board having spike-tooth which can adjust the direction of potted seedling with the action of effective force, the side shield of the vibrating conveying board is wider in the initial part and then gradually becomes narrower, then followed by the leaf grating for the air flow passage and keeping the potted seedling upright, the lower part of the leaf grating is connected with air supply, the lateral section is groove which is similar to the spotted seedling stoup in the shape, blocks are equipped in each exit of the groove, the front end of the block is equipped with seedling-shifting wheel whose number equals to the groove and is driven by shifting wheel axle, each connected with introductory pipe in the front of the seedling-shifting wheel. The device combines the vibrating conveying with air flow, the vibration can make the spotted seedling moving on the vibrating board, while the air flow cam keep the spotted seedling upright, which can realize automatic ordering, and can grow seedling with seedling tray used in traditional artificial rice transplanting.

Description

technical field [0001] The invention relates to agricultural machinery, in particular to an airflow vibration type orderly seedling throwing and separating mechanism. Background technique [0002] Rice is the food crop with the highest yield per unit area, the largest planting area, and the largest total output in my country. Throwing rice seedlings in bowls avoids damage to seedlings and roots when transplanting and separating seedlings in traditional seedling raising methods. There is no obvious regreening period, seedlings tiller early, and yield increase is obvious. [0003] Disorderly throwing seedlings, due to the lack of row spacing, mechanical weeding and deep topdressing cannot be carried out, increasing the application of pesticides and herbicides, resulting in pollution of farmland and downstream waters, which is not conducive to sustainable agricultural development. Orderly throwing seedlings with the advantages of transplanting rice seedlings and traditional th...

AI Technical Summary

Problems solved by technology

At present, the orderly seedling throwing machine researched in China needs to put the seedling tray on the machine when working, and use methods such as pulling out the pot seedlings and pushing out the pot seedlings on the seedling tray to let the pot seedlings fall into the field. Tray seedling raising requires high seedling raising requirements and costs, making it difficult to popularize
