Seedling tray sowing device set

Abstract

The invention discloses a seedling tray sowing device set which comprises a machine frame, a conveying device, substrate filling devices, sowing devices, a hole pressing device, a pneumatic device and a control device. A supporting frame, a motor and a transmission guide rod are arranged below the machine frame. The two ends of the bottom of the supporting frame are respectively provided with a set of land wheels. The output end of the motor is connected with the transmission guide rod. A conveying belt and a seedling tray positioning assembly are installed above the machine frame. The seedling tray positioning assembly is placed on the conveying belt. The control device comprises an electronic control box, a liquid crystal display operation interface, an electrical apparatus element assembling plate, a programmable controller and a plurality of photoelectric sensors. The substrate filling devices, the sowing devices, the hole pressing device, the pneumatic device, the control device and the photoelectric sensors are installed on the machine frame. The two substrate filling devices and the two sowing devices are all connected with a protecting cover and a sowing device motor which is installed on the lower side of the machine frame. All the photoelectric sensors are connected with the electronic control box at one end of the machine frame. The programmable controller in the electronic control box is connected with all the devices. The seedling tray sowing device set has the advantages of being high in automation degree and suitable for seeds with different shapes.

Description

technical field [0001] The invention belongs to the field of agricultural machinery, and in particular relates to a complete set of equipment for sowing seedling trays. Background technique [0002] my country is a big agricultural country and a big consumer of agricultural products. Agricultural production and its products play an important role in the national economy and people's lives. With the increasing demand for agricultural products in economic and social development, traditional agricultural production methods can no longer meet the needs of economic and social development. Crop seedling cultivation and transplanting technology shows the advantages of high yield, high quality and good benefit. Along with this new cultivation technology, industrial seedling cultivation technologies such as greenhouse and greenhouse seedling cultivation have also been applied. important parts of. At present, most of the seedling cultivation in plug trays is carried out by manual su...

AI Technical Summary

Problems solved by technology

my country's plug-in precision seeding equipment started relatively late, and the existing products have shortcomings such as automation, unstable performance, small application range, poor integration of agricultural machinery and agronomy, and low efficiency in practical applications.

[0003] The technology of plug precision seeding equipment in foreign countries is relatively mature, but due to the high price and the difference with my country's agronomic requirements, it is rarely used in China
