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...

Problems solved by technology

On the one hand, it is a problem of hydraulic performance. Due to the unreasonable design of the structure and parameters of the emitter, parameters such as flow rate, flow velocity and soil moisture range cannot meet the requirements of the emitter buried in the ground; on the other hand, the emitter is easily blocked, resulting in irrigation The reason for the blockage of the sprinkler is mainly due to the physical and chemical blockage caused by the presence of tiny particles or water quality in the irrigation water, and the blockage of the outlet of the emitter caused by the growth of plants towards water.
