Automatic control system for circularly picking strawberries in greenhouse

Abstract

The invention discloses an automatic control system for circularly picking strawberries in a greenhouse. The automatic control system comprises a bracket, a planting unit, a driving device, ultrasonic scanners and a controller, wherein the bracket comprises telescopic supporting legs and a fixing frame fixed on the supporting legs; the planting unit is arranged in the fixing frame in a dismountable manner, and comprises 2 planting tanks and 3 blocking and separating nets, which are in mutual alternation and parallel arrangement, a first long edge of each blocking and separating net is pivoted with a long edge of the first planting tank which is the nearest to the first long edge through a shaft, and a second long edge of each blocking and separating net can be in starting-closing connection with a long edge of the second planting tank which is the nearest to the second long edge or a long edge of the fixing frame through an electromagnetic switch; the driving device is used for driving the shafts; and the controller is in communication connection with the supporting legs, the driving device and the ultrasonic scanners. According to the automatic control system disclosed by the invention, the height of the planting unit can be adjusted according to the height of a person entering a planting shed, so that the greenhouse is suitable for different people with different heights to pick the strawberries under the planting unit, the situation that strawberries and strawberry plants are extruded or tramped is avoided, good fruit quality and good plants are maintained, and sustainable picking is maintained.

Description

technical field [0001] The invention relates to an automatic control system for circularly picking strawberries in a greenhouse. Background technique [0002] Strawberries are traditionally cultivated on the ground, and they are planted in the same greenhouse year after year. The nutrient consumption is excessive, and the bacteria and nematodes in the soil are easy to accumulate, which leads to the decline of strawberry yield and quality, and creates obstacles to continuous cropping. There are also some other disadvantages in ground cultivation, such as: the fruit is hidden in the clumps of plants, which is hard to pick and labor-intensive; Rotten fruit, the fruit rate is low. Trellis cultivation adopts the artificial substrate under the condition of the stand, which is convenient to replace every year, can avoid the pollution of the ground to the fruit, overcome the infection of the soil pathogenic bacteria to the plant, and thus ensure the realization of high-quality gree...

Problems solved by technology

The existing scaffolding cultivation method is not convenient for people of different heights to collect, especially the towering scaffolding that gradually rises, the strawberries at the upper end are not easy to pick, and it is easy to crush the strawberries at the lower layer because of picking the strawberries at the upper end , causing waste
