High-precision automatic seedling sowing device and method

Abstract

The invention discloses a high-precision automatic seedling sowing device and method, a seedling tray straightening guide rod is mounted above a seedling tray conveying belt in a crossing manner, and the seedling tray straightening guide rod can rotate positively and negatively by 90 degrees so as to rotate downwards to intercept, straighten a seedling tray and rotate upwards to release the seedling tray; the lateral conveying belts are installed at the two side ends of the seedling tray conveying belt, the lateral conveying belts clamp the seedling trays from the two sides of the seedling trays and convey the seedling trays to pass through the pneumatic seed metering roller, the lateral conveying belts conduct intermittent conveying, intermittent conveying starting and stopping of the lateral conveying belts are synchronous with intermittent rotating starting and stopping of the pneumatic seed metering roller, and the effects of high precision, high efficiency and stable operation are achieved. According to the automatic seed metering device, the problems of automatic seed metering and seed metering precision of seed metering equipment are effectively solved, so that the automatic and long-time operation can be realized, the precision can be ensured, and the high-quality and high-efficiency seed metering effect is achieved.

Description

technical field [0001] The invention relates to the field of equipment for sorting seeds in seedling holes of a seedling tray, in particular to a high-precision automatic seedling sorting device and method. Background technique [0002] The plug tray, also known as the seedling tray, has become an important tool in the factory seedling production process. Whether it is flowers or vegetables, plug seedling cultivation is the most fundamental change in modern gardening, which provides a guarantee for fast and mass production. The materials used to make trays generally include polystyrene foam, polystyrene, polyvinyl chloride, and polypropylene. Manufacturing methods include blow molding and injection molding. Common vegetable and ornamental plant seedling trays are made of polystyrene material. There are many specifications and sizes of seedling trays, most of which are 6 to 10 rows in size, and 9 rows and 18 rows are commonly used. Firstly, it is necessary to fill and pla...

Problems solved by technology

The current automatic seed metering machines often have the problem of low precision. The problems caused by low precision are: the position of seed seeding is not correct, the offset is large, and even the seeds are not qualified for seeding. It needs to be manually shut down to recalibrate the accuracy. As a result, manual monitoring is required. Once the seeding fails, readjustment is required. The maintenance frequency of the machine equipment is high, the cost is high, and the efficiency and seeding quality are affected. Currently, the equipment on the market generally has this problem.
