Embodiment 1

[0031] Please refer to figure 1 and figure 2 , this embodiment provides a lifting water distribution system 100 for water distribution in farmland. The lifting water distribution system 100 includes a lifting water distribution device 110 and a water distribution device 120 . The lifting water distribution device 110 includes a lifting pump 111 and a water distribution device 112. The water distribution device 112 has a water distribution chamber 112a. The outlet of the lifting pump 111 communicates with the water distribution chamber 112a through a water delivery pipe 113. The outlet of the water delivery pipe 113 communicates with the water distribution chamber 112 a, and the lift pump 111 is used to supply water to the water distribution device 112 . The outlet of the water pipe 113 is the first outlet 113a.

[0032] Further, the water distributor 112 is provided with a cleaning port 112b for cleaning the water distribution chamber 112a of the water distributor 112, and...

Embodiment 2

[0057] see Figure 5 , Figure 6 and Figure 7 , the present embodiment provides a lifting water distribution system 200. The difference between the lifting water distribution system 200 and the lifting water distribution system 100 is that the water distributor 112 of the lifting water distribution system 200 has a stirring assembly 220, and the stirring assembly 220 includes a stirring rod 221, stirring impeller 222 and power unit 223. One end of the stirring rod 221 is accommodated in the water distribution chamber 112a of the water distributor 112, the other end of the stirring rod 221 penetrates the side wall of the water distributor 112 and is connected with the power output part of the power unit 223, and the stirring impeller 222 and the stirring rod 221 pass through the bevel gear Mesh connection.

[0058] Further, the axis of the stirring rod 221 coincides with the axis of the water distribution chamber 112a, and the axis of the stirring rod 221 coincides with the...

Embodiment 3

[0077] see Figure 9 , Figure 10 , Figure 11 , Figure 12 and Figure 13 , the present embodiment provides a water level control valve 400 , the water level control valve 400 includes a valve body 410 , a regulator 420 , a valve core 430 and a valve core adjusting rod 470 .

[0078] The valve body 410 has a valve cavity 411 , and the regulator 420 includes an adjusting rod 421 and an adjusting sleeve 422 sleeved on the adjusting rod 421 . The adjusting rod 421 and the adjusting sleeve 422 are threadedly connected. The adjusting rod 421 and the adjusting sleeve 422 can rotate relatively. The adjustment sleeve 422 is protrudingly provided with a slider 422a, the slider 422a protrudes from the side wall of the adjustment sleeve 422 toward the side away from the axis of the adjustment sleeve 422, and the extension direction of the slider 422a is in line with the axis of the adjustment sleeve 422 parallel. The inner wall of the valve main body 410 is provided with a sliding...

Abstract

The invention relates to an irrigation water pretreatment system and a farm irrigation system, which relate to the technical field of agriculture irrigation. The irrigation water pretreatment system comprises a primary precipitation tank, a mixing and adjusting tank, a detection system and a water lifting and distributing system. The primary precipitation tank is communicated with the mixing and adjusting tank, and the detection system is arranged in the mixing and adjusting tank. The water lifting and distributing system comprises a water lifting and allocating apparatus and a water distribution pipe, the water lifting and allocating apparatus comprises a lifting pump and a water allocator, an inlet of the lifting pump is arranged in the mixing and adjusting tank, an outlet of the lifting pump is communicated with the water allocator, and an inlet of the water distribution pipe is communicated with the water allocator. The water allocator is provided with a stirring assembly, and the stirring assembly comprises a stirring rod, a stirring impeller and a power apparatus. One end of the stirring rod is accommodated in the water allocator, the other end penetrates through the water allocator and is connected with a power output portion of the power apparatus, and the stirring impeller is engaged with the stirring rod by virtue of a bevel gear. The farm irrigation system comprises the irrigation water pretreatment system. By adopting the irrigation water pretreatment system and the farm irrigation system, cultivation biogass slurry can satisfy the fertilizing standard, zero emission is realized, and the fertilizer efficiency of the cultivation biogass slurry can be maximized.

Description

technical field [0001] The invention relates to the technical field of agricultural irrigation, in particular to an irrigation water pretreatment system and a farmland irrigation system. Background technique [0002] Breeding biogas slurry has a very high fertilizer efficiency, which can promote the growth of crops very well. Not only can the use of pesticides and fertilizers be reduced, but also the negative effects on soil and crops caused by excessive use of chemical fertilizers and pesticides can be avoided. [0003] The inventors of the present application have discovered through research that directly using aquaculture biogas slurry to fertilize crops will have serious negative effects on the crops and hinder the normal growth of the crops. The aquaculture biogas slurry must be pretreated before it can be used for crop fertilization. [0004] The existing irrigation water pretreatment system is not suitable for pretreatment of aquaculture biogas slurry. The pretreatm...
