Automatic plug tray feeding infiltration seeding device

Abstract

The invention relates to the technical field of soilless culture, in particular to an automatic plug tray feeding infiltration seeding device. The device comprises a belt conveying line, wherein a guide wheel type seed suction and insertion device for inserting seeds into sponge seedling raising trays, a sponge rolling water injection device and a sponge seedling raising tray automatic feeding device are arranged on the belt conveying line in the direction opposite to conveying in sequence. According to the device, automatic feeding of the sponge seedling raising trays can be realized throughcooperative operation of two supporting double-shaft air cylinder groups on the sponge seedling raising tray automatic feeding device, then through reasonable cooperative operation of a pressing mechanism and a water injection mechanism on the sponge rolling water injection device with the belt conveying line, the water outlet end of the water injection mechanism can be tightly attached to the sponge seedling raising trays for water injection, automatic infiltration of the sponge seedling raising trays is achieved, and by reasonable cooperative operation of a seed suction mechanism and a seedinsertion mechanism on the last guide wheel type seed suction and insertion device, seeds can be smoothly inserted into cross grooves of the sponge seedling raising trays. Therefore, full-automatic operation is achieved, and work efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of soilless cultivation, in particular to an automatic tray feeding infiltration sowing equipment. Background technique [0002] Soilless cultivation is a new type of cultivation method. It is an agricultural high-tech that does not use soil to cultivate plants. Because it replaces the soil environment with the artificially created crop root environment, it can effectively solve the difficult problems in traditional soil cultivation. The contradiction between air and nutrient supply makes the root system of crops under the most suitable environmental conditions, thereby exerting the growth potential of crops, and greatly improving the growth and biomass of plants. Among them, hydroponics and aeroponics are two important methods of soilless cultivation, which are characterized in that the seeds are fixed in the sponge seedling tray, and then the plants are grown in the nutrient solution by soaking or spraying...

AI Technical Summary

Problems solved by technology

[0003] The following problems exist in the prior art. In soilless cultivation, the process of sowing seeds to the sponge seedling tray is an important step. At present, the research and design of the seeder mostly use the plug tray as the sowing object, and the sowing of the sponge seedling tray is aimed at There are few automation equipment in the process, and manual operation is used for sponge infiltration and seed pressing, and there is a problem of low work efficiency
