As shown in fig. 1 and 2, the water distribution assembly further comprises a fertilizer supply pipe 111, an elastic telescopic pipe 11 and an adjusting pipe 12, wherein the fertilizer supply pipe 111 is sleeved in the water distribution pipe 1, water mixed with water and fertilizer is conveyed in the fertilizer supply pipe 111, water without water and fertilizer is conveyed in a cavity between the fertilizer supply pipe 111 and the water distribution pipe 1, and accordingly two different irrigation water can be conveyed respectively. One end of the elastic telescopic tube 11 is connected with the adjusting tube 12, the other end of the elastic telescopic tube is connected with the outer sides of the two joints 2 in a fixed connection mode, and the elastic telescopic tube 11 is connected with the fertilizer supply tube 111 through the side wall of the joint 2, so that water and fertilizer can be conveyed into the elastic telescopic tube 11 and the adjusting tube 12.
Specifically, the elastic bellows 11 are connected to both ends of the adjustment tube 12, respectively, so that the adjustment tube 12 is formed in parallel with the connection tube 5. When the water pressure in the fertilizer supply pipe 111 increases, the water pressure can drive the elastic telescopic pipe 11 to elastically expand and stretch, the elastic telescopic pipe 11 can be driven by the water pressure to elastically stretch, and the adjusting pipe 12 can be linked with the lifting pipe 7, so that the lifting pipe 7 can be adjusted in a lifting way.

The lower end of the lifting tube 7 is connected with an annular sleeve 22, and the sleeve 22 is sealed and sleeved outside the adjusting tube 12, so that linkage between the lifting tube 7 and the adjusting tube 12 can be realized, and further, the lifting tube 7 can be regulated and controlled. The lower side of the sleeve 22 is connected with the drip pipe 10, a plurality of water outlet holes 23 are formed in the periphery of the drip pipe 10, the drip pipe 10 is communicated with the second flow passage 16 at the lower end of the lifting pipe 7, and drip pipe water supply can be achieved through the water outlet holes 23. Holes 221 for water and fertilizer to flow out are formed in the periphery of the adjusting pipe 12, the holes 221 are communicated with the sleeve 22, further communicated with the second runner 16 in the lifting pipe 7 and also communicated with the drip pipe 10, and further the effect of supplying water and fertilizer to the drip pipe 10 can be achieved.
As shown in fig. 4 and 5, the adjusting tube 12 has a multi-layer sleeved structure, an outer limit sleeve 26, an inner limit sleeve 27 and two necking tubes 24; the outer limit sleeve 26 and the inner limit sleeve 27 are sleeved with each other, a certain size difference exists between the inner limit sleeve 27 and the outer limit sleeve 26, an annular gap 33 is formed between the outer limit sleeve 26 and the inner limit sleeve 27, a hole 221 is formed in the position, corresponding to the annular gap 33, of the outer limit sleeve 26, the sleeve 22 is communicated through the hole 221, and then the second runner 16 and the drip pipe 10 are communicated.
The two necking pipes 24 are arranged at two ends of the outer limiting sleeve 26, and fixedly connected between the periphery of the necking pipes 24 and the outer limiting sleeve 26; the two necking pipes 24 are of a funnel-shaped structure, the opposite ends are small, and the opposite ends are large. The opposite ends of the two necking pipes 24 are connected with the elastic telescopic pipe 11, and the opposite ends extend into the outer limit sleeve 26 and are connected with the inner limit sleeve 27. The two ends of the adjusting tube 12 are connected between the elastic telescopic tubes 11.
As shown in fig. 5, the middle section of the inner limit sleeve 27 is a closed expansion section 35, and the periphery at the expansion section 35 bulges outwards; the two sides of the expansion section 35 are both water permeable sections 29, and a plurality of gaps 30 are formed in the periphery of the water permeable sections 29, so that a plurality of segmented circular ring structures are formed in the positions of the water permeable sections 29, block-shaped structures are connected between adjacent circular rings, and then the circular ring structures are connected, the gaps 30 are formed between the circular ring structures, and the inner cavities of the inner limiting sleeves 27 can be communicated through the gaps 30, so that water and fertilizer circulation is realized.
Two elastic sleeves 25 are sleeved on the outer side of the inner limiting sleeve 27, and the two elastic sleeves 25 are sleeved on the two sides of the inner limiting sleeve 27 respectively; the elastic sleeve 25 is in a cylindrical shape with elasticity, and can be elastically coated on the periphery of the water permeable section 29 through spontaneous elasticity of the elastic sleeve 25; the gap 30 at the water permeable section 29 can be communicated by the self pressure of the elastic sleeve 25, so that the inner limit sleeve 27 is sealed inside and outside. The elastic sleeve 25 expands when the pressure of the water and fertilizer in the inner side increases, after the elastic sleeve 25 expands, the notch 30 at the permeable section 29 can be opened, and then a larger flow passage structure is formed at the permeable section 29, so that flow states with different sizes in the elastic sleeve 25 are generated.
The elastic sleeve 25 can be elastically expanded, and the elastic sleeve 25 is more easily expanded than the elastic telescopic tube 11, namely, when the water pressure in the water distribution tube 1 is increased, the elastic sleeve 25 is expanded first, and then the elastic telescopic tube 11 is expanded and stretched.
A plurality of sawtooth rings 28 are arranged at the two ends of the inner limiting sleeve 27, which are close to the necking pipe 24, the positions of the elastic sleeve 25 corresponding to the sawtooth rings 28 are clamping sections 31, and an elastic coating state is generated between the clamping sections 31 and the sawtooth rings 28; the elastic sleeve 25 can form mutual cladding fit between the sawtooth rings 28 at the position of the clamping section 31, so that the mounting stability of the elastic sleeve 25 can be improved, and the performance strength of the elastic sleeve 25 is greatly improved.
The opposite ends of the two elastic sleeves 25 extend to the expansion section 35 in the middle of the inner limit sleeve 27, and the elastic sleeves 25 and the expansion section 35 are mutually elastically coated and connected, and the expansion section 35 presents an outwards-raised state, so that a stable connection structure between the elastic sleeves 25 and the expansion section 35 can be maintained, and the stability of the elastic sleeves 25 is maintained.
The elastic sleeve 25 forms elastic deformation limitation between the outer limit sleeve 26 and the inner limit sleeve 27, and plays a role in limiting the expansion size of the elastic sleeve 25. The elastic sleeve 25 corresponds to the middle section position of the permeable section 29, the diameter is smaller, an elastic section 32 is formed, namely, the elastic section 32 can be elastically coated on the periphery of the inner limit sleeve 27 to form a relatively stable sealing coating structure, and the sealing performance in a coating state is greatly improved.
When the water and fertilizer pressure is smaller, the elastic sleeve 25 is coated on the outer peripheral position of the water permeable section 29, and can only pass through the inner limiting sleeve 27 in the regulating pipe 12, so that a narrower channel is formed to form the circulation of water flow. At this time, the water supply in the second flow passage 16 can flow out of the drip pipe 10 through the sleeve 22, thereby realizing drip irrigation.
When the pressure in the elastic sleeve 25 increases, the elastic sleeve 25 begins to expand outwards, the water permeable sections 29 of the elastic sleeve 25 and the inner limit sleeve 27 are separated from each other after expansion, and a larger and open channel is formed between the elastic sleeve 25 and the inner limit sleeve 27, so that the water and fertilizer circulation in the adjusting pipe 12 is facilitated, and the situation that the water and fertilizer is blocked in the adjusting pipe 12 is avoided. When the elastic sleeve 25 expands, the annular gap 33 between the elastic sleeve 25 and the outer limit sleeve 26 starts to shrink, so that a liquid outlet flow passage can be reduced; at this time, the water pressure in the water distribution pipe 1 is increased, so that the liquid outlet state in the drip pipe 10 can be kept stable. After the elastic sleeve 25 is expanded, the space between the elastic sleeve 25 and the inner wall of the outer limit sleeve 26 is further reduced, so that stable liquid discharge of the drip pipe 10 can be maintained, and a drip irrigation state in which liquid discharge is relatively stable can be realized regardless of pressure change.
The opposite ends of the two elastic sleeves 25 have a gap at one end, and the two elastic sleeves 25 are in a disconnected and separated state to form movable ends 34 which are separated from each other.
