Sprout planting room automatic sprinkler control system

Abstract

The invention discloses a full-automatic spraying control system for a bean sprouts planting room, which includes at least one set of spraying devices and a controller, and each of the spraying devices includes a water supply tank, a main water supply pipe and a plurality of water supply pipes along the main water supply pipe. The sub-water supply pipes distributed at intervals in the length direction, one end of the main water supply pipe communicates with the water supply tank, the other end of the main water supply pipe communicates with the sub-water supply pipes, and the sub-water supply pipes include a first branch water pipe and The second branch water pipe, the first branch water pipe and the second branch water pipe are respectively connected with nozzles through nozzle branch pipes; the controller includes a seed soaking mode key, a germination and seedling raising mode key, a spray cycle setting key, Spray duration setting key, spray amount setting key and central processing unit. The invention can not only automatically control the spraying time and duration of seed soaking, germination and seedling raising; the nozzles form a forward and downward fan-shaped micro-spray to realize uniform scattering of spray water.

Description

technical field [0001] The invention belongs to the technical field of bean sprouts planting equipment, in particular to a fully automatic spraying control system for a bean sprouts planting room. Background technique [0002] There are usually three stages in the cultivation process of crop seedlings: soaking seeds, germination and seedling raising. These three stages have different requirements for water. The usual method: first, specially design electronic equipment for control, but the disadvantages of this method are: the design cycle is long, the process is complicated, there is no way to achieve rapid changes, and it is suitable for single seedlings; the second is to use the program-controlled timing socket sold on the market Realize, the shortcoming is: can't satisfy three stages of seed soaking, vernalization and seedling raising of seedling cultivation simultaneously. This is because the periods and durations of spraying in the three processes are different, and ...

Problems solved by technology

The usual method: first, specially design electronic equipment for control, but the disadvantages of this method are: the design cycle is long, the process is complicated, there is no way to achieve rapid changes, and it is suitable for single seedlings; the second is to use the program-controlled timing socket sold on the market The disadvantage is that the three stages of soaking, germination and seedling cultivation cannot be satisfied at the same time

In this way, at least 8*12=96 groups of switches are required within one day at most (one on and one off is a group). The program-controlled timing sockets on the market can set up to 20 groups per day, which cannot meet the switch groups of the most frequent spraying period. number

[0004] In addition, in terms of spraying methods, there are two common spraying methods: one is to use a submersible pump to transport water upwards, and then spray water downwards through a mesh plate; the disadvantage is that the spraying water will easily cause the seeds to move, which will affect the smaller seeds. The second is that the direction of the sprinkler head is downward, and it is sprayed circularly from top to bottom. Due to the physical structure of the sprinkler head, the spraying effect is usually circular spraying, and the central area under the spraying is difficult to reach. spray to
