Embodiment 1

[0022] Such as figure 1 As shown, the automatic water collection and sprinkler irrigation device of the agricultural greenhouse of the present invention includes a water storage tank 1 installed on the top of the greenhouse, and the top of the water storage tank 1 is communicated with a water collection tank 2 for collecting rainwater, and the water collection tank 2 is located at the outer top of the greenhouse. A pH tester 3 is inserted into the sump 2, a control valve 5 is arranged on the communication pipeline 4 between the sump 2 and the reservoir 1, and at least two measuring cylinders 6 are vertically connected to the bottom of the reservoir 1, The bottom of each measuring cylinder 6 is connected with a spray head 7 . A lifting device 9 for controlling the depth of the pH tester 3 in the sump 2 is provided on a side wall of the sump 2 .

Embodiment 2

[0024] Based on Embodiment 1, the pH tester 3 and the control valve 5 are connected to the controller, the control valve 5 is an electronically controlled valve, and the controller makes corresponding actions on the control valve 5 after obtaining the pH value of the pH tester 3 .

Embodiment 3

[0026] Based on the above embodiment, at least two filter screens 8 are arranged inside the communication pipeline 4, and all the filter screens 8 are arranged sequentially in order of decreasing mesh size from top to bottom.

Abstract

The invention discloses an automatic water-collection and spraying device of an agricultural greenhouse. The automatic water-collection and spraying device comprises a reservoir installed at the top of a greenhouse, a water collection groove for collecting rainwater is communicated with the upper portion of the reservoir, the water collection groove is located at the outer top of the greenhouse, a pH testing instrument is inserted into the water collection groove, a communication pipeline between the water collection groove and the reservoir is provided with a control valve, at least two metering cylinders are vertically communicated with the lower portion of the reservoir, and the lower portions of both the metering cylinders are communicated spraying heads. The automatic water-collection and spraying device can collect the rainwater and detect the acidity, available rainwater is obtained, the actual water consumption amount of agricultural irrigation water is adjusted according to the amount of the available rainwater, therefore the water consumption amount of the agricultural irrigation water can be lowered, and the adjustability of the agricultural irrigation water can be achieved at the same time.

Description

technical field [0001] The invention relates to an irrigation device, in particular to an automatic water collection and sprinkler irrigation device for agricultural greenhouses. Background technique [0002] Along with the generation of high molecular polymer-polyvinyl chloride, polyethylene, plastic film is widely used in agriculture. In the early 1950s, Japan, European and American countries successfully applied greenhouse films to cover hotbeds, and then covered small sheds and greenhouses with good results. my country introduced polyvinyl chloride agricultural film in the autumn of 1955. It was first used to cover vegetables in small sheds in Beijing, and achieved the effect of early maturity and increased production. The greenhouse was originally a special equipment for vegetable production. With the development of production, the application of greenhouses has become more and more extensive. At present, greenhouses have been used for potted flower and cut flower cul...
