Automatic homogeneous sprinkling device for matrix material-laying and sprinkling machine

Abstract

The invention discloses an automatic even water spraying device applied in matrix coating materials air washers, which has a frame provided with a spraying component, an infrared photoelectric sensor, a coating material component and a conveyor belt assembly. The conveyor belt assembly is driven through a motor, and an aperture disk is driven through the conveyor belt assembly. The spraying component has a tank in which the inside is provided with a water pipe. A leaching emitter and a solenoid valve are arranged on the water pipe. The device is controlled through a controller. In the invention, the control methods of infrared light sensor and the delay relay are adopted. When the aperture disk passes the photoelectric sensor, a signal is sent. After that, the delay relay is passed. The spraying is controlled to start when the aperture disk arrives at the spraying position. The work is delayed for a certain period of time for the completion of the spraying to the entire aperture disk. The delay time of the delay relay and the photoelectric sensor location can be easily adjusted according to the parameter changes. A multilayer leaching nozzle is adopted for the leaching emitter, in which the structure is a stacking hollow cylindrical structure with 3-5 layers and the diameter of the outlet hole is a slender pore.

Description

Technical field [0001] The invention relates to a sprinkling control device used in a substrate coating sprinkler, in particular to a sprinkling control device of a substrate coating machine used in a seedling raising production line in a facility. It is a kind of planting and seedling cultivation suitable for the agriculture, forestry and flower industry in the facility. Background technique [0002] In recent years, the mechanized seedling production line has been rapidly applied at home and abroad. As the main technology in the mechanization of facility gardening, the seedling production line is based on a porous plug tray with a mixture of peat, vermiculite, perlite and other materials as the matrix (the density is very high). (Light) A modern production system for mechanized seeding and factory seedling cultivation can increase the yield and quality of agricultural products in gardening facilities, and ensure clean and safe. Seedling production lines at home and abroad gener...

Problems solved by technology

However, the trays are rectangular, which causes uneven spraying on the trays during conveying and spraying, and also causes most of the sprayed water to be outside the trays, resulting in waste and the need for recycling.

There is also a small hole shower head for showering. Due to the low density and light weight of the substrate, the shower water is too fast, which causes the substrate and the seeds to go to the hole during the shower, which affects the operation quality of the entire production line.
