[0026] Embodiment one

[0027] As Figure 1 With Figure 2 As shown in a kind of lifting type tee feed device for farmland irrigation, including tee main body 1, flow control assembly 2 is arranged in the side of tee main body 1, and the top of tee main body 1 is connected with connection control assembly 3, and the top of connection control assembly 3 is installed with lifting control assembly 4;Lifting control assembly 4, including control shell 401, water outlet 402, screw cap 403, block plug 404, sealing rubber ring 405, spring 406, lifting rod 407, limit plate 408, block plug 404 of lifting control assembly 4 can be slid up and down by lifting rod 407, to control water flow by simple lifting operation, block plug 404 is connected with water outlet 402 and screw cap 403 by spring 406 to form elastic structure, and screw cap 403 and control shell 401 form thread detachable structure, sealing rubber ring 405 is closely attached between block plug 404, lifting rod 407 is connected with screw cap 403 to form clamping structure by limit plate 408;Block plug 404 can be slid up and down by lifting rod 407, to control water flow by simple lifting operation, so that irrigation process is more convenient, and block plug 404 can better block water flow by the elasticity of spring 406, in addition, sealing rubber ring 405 is arranged on the outer wall of block plug 404, and sealing rubber ring 405 can effectively prevent water from leaking from the joint.

[0028] As Figure 1 With Figure 3 As shown in a kind of lifting type tee feed device for farmland irrigation, connection control assembly 3, including fixed head 301, rotating disc 302, control block 303, threaded joint 304, sealing head 305, connection control assembly 3 is connected with tee main body 1 for control shell 401, and the connection mode is simple and convenient, threaded joint 304 and sealing head 305 form threaded sealing structure, and threaded joint 304 is connected with fixed head 301 by control block 303 and rotating disc 302 to form rotating structure;Sealing head 305 is aligned with threaded joint 304, and threaded joint 304 is rotated, at this time, fixed head 301 is connected with sealing head 305, so that control shell 401 is connected with tee main body 1, the connection mode is simple and convenient, and is convenient to use.

[0029] As Figure 1 , Figure 4 With Figure 5 As shown in a kind of field irrigation pull type tee feed device, flow control component 2, including flow pipe 201, fixed seat 202, threaded rod 203, control ball 204, flow control component 2 can control the opening and closing of flow pipe 201, control ball 204 is lifted by threaded rod 203 and flow pipe 201 constitutes structure, and threaded rod 203 and fixed seat 202 constitute screw connection;By rotating threaded rod 203 will make control ball 204 rise or fall in fixed seat 202, to this can control the opening and closing of flow pipe 201, to control the water flow size of water flow through tee pipe main body 1 into control housing 401.

[0030] Working principle: first, seal head 305 is aligned with threaded joint 304 and rotates threaded joint 304 simultaneously, threaded joint 304 will rotate in fixed head 301 by rotating disc 302 at this time, to this will rotate threaded joint 304 into seal head 305, at this time will make control housing 401 connect with tee pipe main body 1 by seal head 305, threaded joint 304, then, rotate threaded rod 203, threaded rod 203 will make control ball 204 rise in fixed seat 202 at this time, and make control ball 204 separate from flow pipe 201, so that the pipeline of flow pipe 201 is opened, the height of control ball 204 rising will control the pipeline opening size of flow pipe 201, so as to adjust the size of water flow;

[0031] Next, when irrigation is needed, the lifting rod 407 can be pulled upwards. The lifting rod 407 will cause the blockage block 404 to slide upwards, thus opening the pipe at the outlet 402. Simultaneously, the lifting rod 407 will cause the limiting plate 408 to slide upwards, positioning it at the top of the threaded cap 403. Rotating the lifting rod 407 will then cause the limiting plate 408 to rotate, locking it at the top of the threaded cap 403. The lifting rod 407 can then be released. The blockage block 404, locked by the limiting plate 408, will be unable to fall to the bottom of the control housing 401. As the lifting rod 407 slides upwards, it simultaneously compresses the spring 406, allowing water to flow through the outlet 402. The water flows out to irrigate the farmland. When irrigation is not needed, the lifting rod 407 can be rotated so that the limiting plate 408 overlaps with the hole in the threaded cover 403. At this time, the lifting rod 407 will drive the blocking block 404 to slide downward, and the blocking block 404 will better block the water flow. At the same time, a spring 406 is provided on the top of the blocking block 404, which can provide a certain downward pressure to the blocking block 404. In addition, a sealing ring 405 is provided on the outer wall of the blocking block 404, which can effectively prevent water from leaking from the joint. When the sealing ring 405 or the spring 406 is damaged and needs to be replaced, the threaded cover 403 can be rotated out from the control housing 401 to inspect and replace the internal parts.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
