Problems solved by technology

Moreover, the inlaid cylindrical dripper used in China has the disadvantage of stress concentration in structure, and does not have the ability to resist rolling. Once it is rolled, it will destroy the flow channel characteristics of the dripper, resulting in dripper blockage and insufficient flow. uniform

Embodiment Construction

[0014] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0015] Such as Figure 1-Figure 3 As shown, a flat dripper, which is a flat and long integrated structure, is provided with a water inlet filter window 1 at one end of its adhesive surface, and a narrow, long and sharply turning tooth-shaped flow channel 2 is adjacent to the water inlet filter along the length direction. The window setting, the water inlet filter window 1 is relatively large, which ensures that the water inlet filter window 1 will not be blocked, thereby ensuring the stability of the water intake. The toothed flow channel 2 is designed to be narrow, long and sharply turning. The internal water flow is always kept at high speed, no sediment will be deposited, and the entire channel is kept unobstructed.

[0016] The tooth-shaped flow channel 2 is connected with the water inlet of the water inlet filter window 1, the water outlet of the tooth-shaped f...

Abstract

The invention provides a flat dripping head. The dripping head is of a flat long integrated structure, a water inlet and filtering window is formed in one end of a sticking surface of the dripping head, and a narrow and long tooth-shaped flow channel with a sudden turn is arranged in a position closely adjacent to the water inlet and filtering window in the length direction; the tooth-shaped flow channel is communicated with the water inlet of the water inlet and filtering window, and the water outlet of the tooth-shaped flow channel is communicated with a water outlet groove; long and thin grooves and short through grooves are formed in one side or two sides of the tooth-shaped flow channel, the long and thin grooves and the short through grooves are also formed in the end part of the water outlet groove of the flat dripping head, and groove ribs and a screening table are arranged on the back surface of the flat dripping head. The sticking surface of the flat dripping head is an arc surface, and the bottom surface of the water outlet groove is a surface with a circular top. According to the dripping head disclosed by the invention, the overall layout is uniform, the dripping head has the remarkable clogging, rolling, folding and stretching resistant capacities, the sticking effect is good, and the service life is long; through the adoption of the dripping head, the situation that liquid nutrients and fertilizer which are mixed with water dropwise, accurately and uniformly flow to crops can be ensured, so that the crops can obtain the optimal water and nutrients as required.

Description

technical field [0001] The invention relates to agricultural water-saving irrigation equipment, in particular to a flat dripper. Background technique [0002] With the increasing social demand for water resources, the contradiction between demand and supply has become more and more obvious. After ensuring the normal water use of residents, how to solve the problem of water shortage in industrial agriculture has become the current focus. As far as agriculture is concerned, it has become an important research topic of the drip irrigation revolution, especially for the core component of the drip irrigation equipment --- the dripper (also called dripper) research. Moreover, the inlaid cylindrical dripper used in China has the disadvantage of stress concentration in structure, and does not have the ability to resist rolling. Once it is rolled, it will destroy the flow channel characteristics of the dripper, resulting in dripper blockage and insufficient flow. uniform. Content...
