Water-saving irrigation and fertilization device for dry farming

Abstract

The invention provides a water-saving irrigation and fertilization device for dry farming. The water-saving irrigation and fertilization device comprises a mounting frame; a water pump is mounted in the middle of the top of the mounting frame; a filtering tank is mounted at the right side of the top of the mounting frame; a folding crank is rotatably connected to the rear side of the top of a fertilizer and water mixing barrel, the front end of the folding crank is in transmission connection with the right end of a transmission rod, and the left end of the transmission rod is in transmission connection with the bottom of a lifting screw rod; the lifting screw rod is in threaded connection with a lifting table; and a driving motor is mounted at the top of the lifting table. According to the water-saving irrigation and fertilization device, a fertilizer aqueous solution is pumped into an inner cavity of the filter tank from a pipeline at the bottom of the left side of the filter tank through the water pump, and then the fertilizer aqueous solution passes through three layers of filter screens when overflowing from the bottom of the filter tank to a filtered water outlet, and the filter screens can block large particles in the fertilizer aqueous solution on the lower layer of the filter tank, so that the large particles are prevented from entering a drip irrigation pipeline, the phenomenon that a drip irrigation head is blocked is reduced, and the drip irrigation head has a good drip irrigation effect.

Description

technical field [0001] The invention belongs to the technical field of agricultural pipe irrigation, and more specifically relates to a water-saving irrigation and fertilization device for dry farming agriculture. Background technique [0002] Water-saving irrigation is to obtain the maximum output or income with the minimum amount of water, that is, to maximize the crop yield and output value per unit of irrigation water. Fertigation is to fertilize through the irrigation system. Fertigation technology is to The way of irrigation and fertilization is established by combining the two basic factors of crop growth and development, water and nutrients. [0003] For the water-saving irrigation and fertilization device for dry farming agriculture, please refer to the CN108934378B patent, which mainly includes a batching tank; a mixing tank, in which there are multiple annular partitions, and diversion holes are provided at the upper and lower ends of each annular partition; Stir...

Problems solved by technology

[0005] In order to solve the above-mentioned technical problems, the present invention provides a water-saving irrigation and fertilization device for dry farming agriculture to solve the problem that the existing similar irrigation and fertilization devices for dry farming agriculture cannot be well mixed with water-soluble fertilizers due to poor stirring force during use. The water is mixed, so that the water-soluble fertilizer cannot be fully dissolved, resulting in a large number of large particles in the fertilizer solution, causing the large particles to block the drip irrigation dripper and affecting the irrigation of crops.
