Combined water culture nutrient solution spraying pipe

Abstract

The invention discloses a combined water culture nutrient solution spraying pipe which can adjust the angle of a sprayer and can be combined and expanded to be applicable to plant culture racks with different specifications. A first joint and a second joint can be connected with a bamboo joint pipe, so that length extension and free-angle bending of the first joint and the second joint are implemented, and the spraying angle is adjusted. The spraying pipe is characterized in that a communication channel is formed in a joint body, horizontally penetrates the joint body and extends downwards toform a vertical channel, the vertical channel penetrates the bottom of the joint body, a valve element is rotatably arranged in the joint body and positioned at a communication position of the communication channel and the vertical channel, a T-shaped channel is formed in the valve element and corresponds to the communication channel and the vertical channel, a knob is positioned outside the jointbody, a shaft on the knob is connected with the valve element, and a label is arranged on the knob and corresponds to the T-shaped channel.

Description

technical field [0001] The invention relates to a combined spray pipe for hydroponic nutrient solution, which relates to a combined spray pipe for spraying a hydroponic nutrient solution and belongs to the field of agricultural planting. In particular, it relates to a hydroponic nutrient solution spray pipe capable of adjusting the angle of the spray head and capable of being combined and expanded to be suitable for plant cultivation racks of different specifications. Background technique [0002] Hydroponics is a new type of plant soilless cultivation method, also known as nutrient liquid culture. Its core is to directly infiltrate the root system of the plant in the nutrient solution. This nutrient solution can replace the soil and provide water, nutrients, oxygen, etc. to the plant. Growth factors enable plants to grow normally. At present, when plant hydroponic irrigation is sprayed, spray pipes are usually used to irrigate the culture solution on the upper side of the p...

[0002] Hydroponics is a new type of plant soilless cultivation method, also known as nutrient liquid culture. Its core is to directly infiltrate the root system of the plant in the nutrient solution. This nutrient solution can replace the soil and provide water, nutrients, oxygen, etc. to the plant. Growth factors enable plants to grow normally. At present, when plant hydroponic irrigation is sprayed, spray pipes are usually used to irrigate the culture solution on the upper side of the plants, and the spray direction of the fixed spray pipes is sometimes It cannot satisfy the uniform spraying of plants, and needs to be properly adjusted. However, because its position and nozzle angle are fixed, it cannot be adjusted flexibly. It is inconvenient to re-install and debug. The size and shape of the cultivation units of the standard plant cultivation racks are different, which is inconvenient when installing and arranging the spray pipes

[0003] The notification number CN108782170A discloses an agricultural irrigation device, which includes a water storage tank, a water pump, a control cabinet, a spray pipe and an initial irrigation pipe. The right end of the water storage tank is connected to a water injection port. A water pump is installed at the left end, a control cabinet is installed at the lower end of the water pump, a battery is installed at the lower end of the control cabinet, a solar photovoltaic panel is installed at the upper end of the water pump and the reservoir, a three-way control valve is installed at the left end of the water pump, an initial irrigation pipe is installed at the left end of the three-way control valve, and an initial irrigation pipe is installed at the lower end of the initial irrigation pipe. The spray pipe, the spray pipe cannot be adjusted at an appropriate angle, and as the growth of the plants changes, it is easy to produce uneven spraying when spraying again

[0004] Notification number CN207411063U discloses a kind of irrigation and sprinkler system for the planting of racks, including a spray pipe and a water injection pump connected with the spray pipe, the spray pipe is provided with at least two nozzles, and the spray pipe The end is provided with an atomizing nozzle for spraying irrigation, and a swivel valve for connection is provided between the nozzle pipe and the atomizing nozzle, and the open end face of one end of the swivel valve is fixedly connected with the water inlet end face of the atomizing nozzle; The movable sealing connection between the swivel valve and the spray pipe; by turning the swivel valve, the semicircular partition and the diversion inclined platform are blocked or form a passage, and the spray angle of the spray pipe is fixed. It is inconvenient to adjust the spray angle, which affects the overall spray effect of the hanger
