Air suction type whole-tray and plug alignment seedling production seeding device

Abstract

The invention discloses an air suction type whole-tray and plug alignment seedling production seeding device which is mainly designed for plug seedling production seeding of fruits or vegetables of small individual growers. Each of a seed tray and plug trays has the same plug slots which are uniformly distributed, seeds are arranged in the plug slots, and a seed suction tray is provided with suction wholes of which the distribution and number are the same as those of the plug slots of the seed trays and the plug trays; the movement trajectory of the seed suction tray is controlled by movement of a parallel four-bar mechanism to implement alternate movement between the seed trays and the plug tray; an air exhaust seed dropping component consists of a fixed pulley, a steel wire rope, a spring and a piston, one end of the steel wire rope is connected with the piston, the other end of the steel wire rope is connected with the parallel four-bar mechanism through a machine frame, and the steel wire rope is pulled by the parallel four-bar mechanism to control separation and blocking of the piston and a vent pipe to implement ingenious linkage of seed suction blocking and seed dropping separation. The device is simple in overall structure, low in cost, stable in running during work and easy to popularize, and the plug seedling seeding accuracy and efficiency of the small individual growers are improved.

Description

technical field [0001] The invention relates to a device for raising and sowing seedlings in plug trays, in particular to an air-suction type device for raising and seeding seedlings in a pair of hole trays. Background technique [0002] Seedling cultivation in plug trays is the key technology for seedling cultivation and transplanting, and the seedling tray seedling machine is the key equipment to ensure the quality of seedling trays. At present, there are mainly two types of pneumatic type and magnetic suction type in terms of working principle. Pneumatic type is widely used. There are mainly three types: pinhole type, plate type and drum type. Mechanical technology, mechatronics technology, and electronic and electrical control technology, etc., are relatively high in cost and expensive, and are suitable for large-scale industrial seedling cultivation.

AI Technical Summary

Problems solved by technology

At present, there are mainly two types of pneumatic type and magnetic suction type in terms of working principle. Pneumatic type is widely used. There are mainly three types: pinhole type, plate type and drum type. Mechanical technology, mechatronics technology and electronic and electrical control technology, etc., are relatively high in cost and expensive, and are suitable for large-scale industrial seedling cultivation

However, my country's planting mode is more scattered planting and less large-scale planting. Due to the large investment in seedling raising machinery, the purchasing power of farmers is low.

According to investigations, most of the vegetables and fruits of small-scale greenhouse growers are still artificially sown on demand, which has problems such as low efficiency, labor and time-consuming, difficult control of sowing depth, and uneven emergence of seedlings.
