Automatic potted seedling transplanter and control method thereof

Abstract

The invention provides an automatic potted seedling transplanter and a control method thereof. The automatic potted seedling transplanter comprises a chassis bracket, planting mechanism, seedling separating mechanisms, seedling guiding devices, a power mechanism, a moving box mechanism and a seedling picking mechanism, the moving box mechanism mounted on the chassis bracket, the seedling picking mechanism is mounted on the moving box mechanism, two sets of the seedling separating mechanisms are symmetrically arranged at two sides of the moving box mechanism through the chassis bracket, the seedling guiding devices are arranged above the seedling separating mechanisms, and the planting mechanisms are arranged below the seedling separating mechanisms. The automatic potted seedling transplanter can realize non-interval whole row seedling picking of pots with various specifications and seedling dropping under the synergistic effects of all the mechanisms and a control system, so the efficiency and the success rate of seedling picking and dropping are improved; the pots are only longitudinally conveyed and moved, so the pot conveying efficiency is improved; pins of seedling claws have acarding effect on potted seedlings before being inserted into the pots, so the seedling picking quality is improved; and the seedling guiding devices receive the seedlings in a stationary state, andshorten a free-fall motion distance, so seedling dropping is accurate.

Description

technical field [0001] The invention relates to the field of agricultural machinery, in particular to an automatic transplanter for plug seedlings and a control method thereof. Background technique [0002] Vegetables are an indispensable type of food in life. my country's planting area has reached 300 million mu, with an annual output of more than 700 million tons, and it continues to grow. It is the largest vegetable producer and consumer in the world. At present, the cultivation of agricultural vegetables in my country mostly adopts the method of raising seedlings in hole trays first, and then transplanting and planting. This method can make vegetables avoid natural disasters such as drought and freezing damage during the seedling cultivation period, and can make full use of light and heat resources, which has the function of climate compensation. And the effect of making crops ripen early and increasing production has huge economic and social benefits, so the research and...

Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the present invention provides an automatic transplanter for seedlings in trays and its control method, which can realize taking seedlings in a row without intervals and throwing seedlings at the same time, which overcomes the problems caused by taking seedlings at intervals and throwing seedlings sequentially. It is difficult to control the seedling throwing time and the success rate of seedling throwing is low, and the tray only needs to do longitudinal conveying movement, which improves the efficiency of tray conveying, seedling picking and seedling throwing; by changing the number of seedling claws, it can adapt to 72 holes , 128 holes and other plugs; adopt the seedling claw to reach the seedling point first, and then wait for the entire row of seedlings to be transported to the bottom of the seedling claw to pick the seedlings, so that the seedling claw needle is inserted into the pot body Before, it played a role in sorting out the pot seedlings, which can separate the leaves of adjacent pot seedlings that are intertwined together, and overcome the clamping and injury of seedlings caused by the existing seedling claws directly inserted into the pot body from the top of the pot seedlings to take seedlings phenomenon, which reduces the damage to pot seedlings and improves the quality of seedling picking; the seedling guide device statically picks seedlings and shortens the free fall distance, making seedling throwing more accurate. There are two sets of seedling picking, seedling throwing, seedling separation, and planting devices , to adapt to the requirements of different row spacing for different crops when transplanting
