[0001] The utility model relates to the field of greenhouse irrigation, and particularly relates to a timing irrigation device for a greenhouse. Background Technique

[0002] Greenhouse irrigation needs to consider multiple aspects. Through reasonable water source selection, pipeline layout, equipment selection, and automatic control measures, efficient and precise irrigation management can be achieved, providing good conditions for plant growth. In order to achieve automated and intelligent irrigation management, a timing and control system is essential. This system can set appropriate irrigation times and water volumes according to the plant growth cycle, environmental factors, etc., to achieve precise irrigation.

[0003] The existing greenhouse timing irrigation device sets a fixed time and conducts the same irrigation operation on any planting soil in the greenhouse. However, since there are multiple plants in the greenhouse and their water supply requirements are different, direct irrigation will cause waterlogging in some plants, affecting the normal growth of the plants.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] To make the purpose, technical solution and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below in conjunction with the specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present utility model. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concept of the present utility model.

[0023] AsFigures 1-3 As shown in the figure, a timing irrigation device for a greenhouse proposed by the present utility model includes an irrigation controller 11 with a built-in control chip. A display screen 12 and an operation console 13 are provided on the front surface of the irrigation controller 11. The opening and closing time can be input through the operation console 13 to perform timing irrigation;

[0024] The water passing mechanism includes a water passing valve 21 provided on the irrigation controller 11. A through inlet end seat 22 and a water supply end seat 23 are formed on the water passing valve 21. The water supply end seat 23 is connected to a five-way member 24 through a pipeline;

[0025] The support mechanism includes a plurality of brackets 41 arranged in the greenhouse. An "L-shaped" foot seat 42 is provided at the lower part of the bracket 41. A ground locking bolt 43 penetrating into the soil is installed on the foot seat 42. A sensor 51 is provided on the foot seat 42, and a sensing terminal 52 penetrating the ground locking bolt 43 is installed on the sensor 51;

[0026] The irrigation mechanism includes an electromagnetic valve 31 provided on the bracket 41. The electromagnetic valve 31 is connected to the five-way member 24 through a pipeline, and an irrigation nozzle 32 is installed at the output end. A nozzle end seat 33 with spray holes is formed on the irrigation nozzle 32.

[0027] It should be noted that: the irrigation controller 11, the electromagnetic valve 31, and the sensor 51 are signal-connected; the irrigation controller 11 is used to control the opening and closing of the channel at the water passing valve 21, the electromagnetic valve 31 is used to control the opening and closing of the channel at the irrigation nozzle 32, and the sensor 51 transmits the opening and closing reference data to the irrigation controller 11 and the electromagnetic valve 31 respectively.

[0028] It should be added that: a water supply path is established between the irrigation nozzle 32 and the water passing valve 21 through the five-way member 24 and the pipeline to transmit the irrigation water.

[0029] In this embodiment, a support mechanism for installing an auxiliary irrigation mechanism is arranged beside the plant. The bracket 41 is supported on the soil surface through the foot seat 42, and the bracket 41 is reinforced by penetrating the ground locking bolt 43 into the soil, realizing the stable placement of the irrigation mechanism at the plant soil. The ground locking bolt 43 is improved, and a soil temperature sensor and a soil humidity sensor for detecting the soil temperature and humidity are arranged inside it to detect the soil temperature and humidity;
