Micro moisting and irrigation suction type douche

Abstract

The present invention relates to a micro-irrigation suction-type douche and comprises a cushion chamber. The present invention is characterized in that a water-conducting core that passes through the wall of the douche is arranged on the cushion chamber, and the water-conducting core passes through a positioning block that is arranged inside the cushion chamber. The length of the cushion chamber is more than or equal to 2 cm and is less than 4 cm. The front end and the rear end of the cushion chamber are reduced and are connected with a junction pipe. Compared with the prior art, the present invention has the unique characteristic that the suction effect of the capillary tube of the water conducting core is used to suck the water from the pipeline so as to irrigate the crops. The structure technical parameters of the present invention are achieved from the great amount of indoor and field experiment data; therefore, the present invention can satisfy the requirement to be buried underground; especially the horizontal moisture range and the upward vertical penetration depth meet the requirement for the douche to be popularized in the field. The douche of the present invention has the advantages of water saving, high irrigation efficiency, simple structure, low cost, low working water head, good block-resistant performance, etc. thereby having higher popularization value.

Description

technical field

[0001] The patent of the present invention relates to a new agricultural irrigation technology, in particular to a micro-moist irrigation technology working under low pressure conditions, and the irrigation technology is realized by a micro-moist irrigation suction type irrigator. Background technique

[0002] At present, the traditional flood irrigation method is still used in most rural areas of our country, resulting in a great waste of water resources. With the development of science and technology, irrigation technology is also constantly innovating and improving. The development of high-efficiency water-saving equipment is one of the key issues in the development of modern agriculture. In order to improve the irrigation effect and effectively increase the water utilization rate, an irrigation method suitable for dryland agriculture-micro-moisture irrigation technology is experimentally studied by our institute. Micro-moisture irrigation technology is a...

Embodiment Construction

[0017] Please refer to figure 1 , the micro-moist irrigation suction sprinkler in the present invention includes a buffer chamber 1 and a water guiding core 2. The buffer cavity 1 has a length of 3 cm, an inner diameter of 1.0 cm, and an outer diameter of 1.4 cm. The front and rear ends of the buffer cavity 1 are provided with nozzles 3 with reduced diameters. And the connecting port 3 and the buffer chamber 1 are an integral structure. The length of the mouthpiece is 1.1cm, the inner diameter of the mouthpiece is 0.55cm, and the outer diameter is 0.77cm; the water guide core 2 is made of spandex low elastic yarn, and its length is 9cm, and the water guide core 2 passes through the buffer chamber 1 in turn The upper casing 18, the positioning block 17 and the lower casing 19 of the buffer chamber 1, and the water guide core accounts for 80% of the aperture area ratio of the buffer chamber 1, and the part of the water guide core 2 located outside the buffer chamber 1 can be pl...
