Airflow vibrating type ordered seedling throwing machine

Abstract

The invention discloses a pneumatic-vibratory device for ordered rice transplanting, comprising two identical seedling-separating device, 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 drived by shifting wheel axle, each connected with introductory pipe in the front of the seedling-shifting wheel. The two shifting wheel axle are supported in the supporting base, the seedling storage tank is fixed in the middle of the cradle; the power are connected with vibrating device and air supply separately, the reducer casing of the seedling-shifting wheel is connected to the seedling-shifting wheel through the shifting wheel axle; the cradle is fixed to the carriage, which connected with dragging device. The device combines the vibrating conveying and airflow, which can realize automatic ordering and rice transplanting.

Description

technical field [0001] The invention relates to agricultural machinery, in particular to an airflow vibration type orderly throwing rice seedling machine. 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 throwing rice ...

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
