Description

Technical Field

[0001] The invention relates to the technical field of sprinkler irrigation machines, in particular to a central support shaft sprinkler irrigation machine integrating water and fertilizer. Background Art

[0002] A center pivot sprinkler is a sprinkler that can rotate at a fixed point like a pointer to irrigate. It can effectively irrigate within its coverage area, and the sprinkler can select brackets of different lengths for sprinkler irrigation according to the needs of use. However, the existing center pivot sprinkler still has certain usage defects during use. When the height of the nozzle of the existing sprinkler system needs to be adjusted, the nozzles need to be adjusted manually one by one, which is cumbersome to operate and leads to low reliability.

[0003] The patent authorization announcement number CN211020357U discloses a pointer-type sprinkler. One end of the "U"-shaped connecting pipe is welded and fixed to the horizontal pipe. The other end of the "U"-shaped connecting pipe is connected to the top of the PE vertical pipe by a thread and locked by a first locking nut. The bottom end of the PE vertical pipe is connected to the top of the connecting hose by a thread and locked by a second locking nut. It can effectively prevent the PE vertical pipe of the lower hanging sprinkler head from falling off, making the connection of the PE vertical pipe more secure. When the height of the sprinkler head needs to be adjusted, the two sets of drive motors are started synchronously. The two sets of drive motors respectively drive the two sets of lead screws to rotate synchronously, thereby driving the lifting plate to rise and fall, thereby adjusting the height of the sprinkler head on the entire truss, making it convenient to adjust the height of the sprinkler head according to the growth of crops and improving reliability.

[0004] In the above-mentioned public patent, the sprinkler in the patent solves the above-mentioned problems, but the sprinkler still has the following problems. During the operation of the sprinkler, water needs to be sprayed through the sprinkler head for irrigation. In the process of irrigating crops, in order to ensure the healthy growth of crops, fertilizers need to be spread on the crops to improve conditions for rapid growth of crops. However, the sprinkler can only perform sprinkler irrigation operations, and fertilization needs to be done manually. Manual fertilization will increase labor costs, which seriously affects the convenience of using the sprinkler.

[0005] In response to the above problems, it is urgent to carry out innovative design based on the original sprinkler structure. Summary of the Invention

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] In a specific embodiment, Figure 1-Figure 3 As shown, the working process of the center support type sprinkler is disclosed, including a support frame 1 and a movable roller 2 provided at the lower end of the support frame 1; a driving structure 3 is provided between the two sets of movable rollers 2, a water pipe 4 is provided on the outer side of the upper end of the support frame 1, and a connecting frame 5 is provided at the lower end of the water pipe 4, a water spray pipe 6 is fixedly installed at the lower end of the water spray pipe 4, and a water spray head 7 is threadedly installed at the lower end of the water spray pipe 6.

[0028] When using the integrated water and fertilizer center pivot sprinkler, the water flow inside the water pipe 4 needs to be transported to the inside of the sprinkler head 7 through the sprinkler pipe 6. At this time, the water flow can be sprayed out through the sprinkler head 7 to irrigate the crops. During the irrigation process, the driving structure 3 will work and rotate the movable roller 2. At this time, the center pivot sprinkler can be rotated and the irrigation process can be completed. During the irrigation process, the support frame 1 will rotate like the pointer inside a clock. At this time, the supporting impeller 11 will contact the ground and ensure the stability of the water pipe 4. By adding fertilizer to the inside of the fertilization frame 13, the sprinkler can automatically fertilize, thereby achieving the integrated water and fertilizer operation effect and improving the convenience of the sprinkler.

[0029] In one specific embodiment, Figure 1-Figure 5 As shown, the stable working process of the sprinkler is disclosed.

[0030] A support structure for controlling the stable operation of the sprinkler is provided between the two groups of support frames 1. The support structure includes a mounting plate 8, and the mounting plate 8 is fixedly installed between the two groups of support frames 1, and the mounting plate 8 is located at the upper end of the sprinkler head 7. At the same time, a connecting rod 12 is fixedly installed between the upper end of the mounting plate 8 and the support frame 1, and a support rod 9 is fixedly installed at the lower end of the mounting plate 8, and a rotating rod 10 is installed through the interior of the support rod 9, and support impellers 11 are fixedly installed at both ends of the rotating rod 10, and the lower end surface of the support impeller 11 is flush with the lower end surface of the movable roller 2, and a fixing rod 22 is fixedly installed at the upper end of the mounting plate 8, and the upper end of the fixing rod 22 is fixedly connected to the water pipe 4.

[0031] When using the integrated water and fertilizer center-support sprinkler, the support impeller 11 will rotate along with the operation of the sprinkler. At this time, the support impeller 11 can drive the rotating rod 10 to move inside the support rod 9, and the support rod 9 will support the mounting plate 8. The holes and grooves opened inside the mounting plate 8 will reduce its own weight. At the same time, the upper end of the mounting plate 8 will support the water pipe 4 through the fixed rod 22, thereby improving the stability of the support between the internal structures of the sprinkler. Setting the support impeller 11 into this structure can reduce its crushing of crops, thereby improving the overall convenience and safety of the use of the device.

[0032] Based on the above embodiments, Figures 1-6 As shown, the process of automatic fertilization by the sprinkler is disclosed.

[0033] The outer side of the support frame 1 is provided with an automatic fertilization feeding structure for cooperation with irrigation. The feeding structure includes a fertilization frame 13, and the fertilization frame 13 is fixedly mounted on the upper end of the mounting plate 8, and a fertilization plate 14 is slidably mounted inside the fertilization frame 13, and a sealing plate 15 is slidably mounted inside the mounting plate 8, and the sealing plate 15 is fixedly connected to the fertilization plate 14, and a lifting plate 16 is fixedly mounted on the lower end of the sealing plate 15, and a telescopic rod 17 is fixedly mounted on the upper end of the lifting plate 16, and the upper end of the telescopic rod 17 is fixedly connected to the lower end of the mounting plate 8, and a driven rod 18 is rotatably mounted on the lower end of the mounting plate 8, and a belt gear structure 20 is provided on the outer side of the driven rod 18 and the rotating rod 10, and a driving wheel 19 is fixedly mounted on the outer side of the driven rod 18, and a rotating push rod 21 is rotatably mounted on the outer side of the driving wheel 19, and the end of the rotating push rod 21 away from the driving wheel 19 is rotatably connected to the lower end of the sealing plate 15.

[0034] Before using the integrated water and fertilizer center pivot sprinkler, it is necessary to pour fertilizer into the fertilizer frame 13. During the rotation of the sprinkler for irrigation, the fertilizer can be automatically added through the fertilizer frame 13, thereby achieving the effect of automatic irrigation and fertilization of the sprinkler; in this process, it is necessary to use a belt gear structure 20 to make the rotating rod 10 drive the driven rod 18 to rotate, and the rotation of the driven rod 18 will drive the driving wheels 19 fixed at both ends to rotate, and the rotation of the driving wheel 19 will push the sealing plate 15 up and down by rotating the push rod 21, and the up and down movement of the sealing plate 15 will synchronously drive the fertilizing plate 14 up and down, and in the process of up and down movement, the fertilizing plate 14 and the sealing plate 15 will successively be separated from the fertilizing frame 13 and the mounting plate 8 respectively. The fertilizer inside the fertilizing frame 13 will pass through the gap and enter the interior of the mounting plate 8 and be discharged through the mounting plate 8, and the lifting plate 16 will follow the sealing plate 15 to move up and down and cause the telescopic rod 17 to shrink, thereby ensuring the stability of the lifting of the fertilizing plate 14 and the sealing plate 15. At this point, the automatic fertilizing process is completed. After fertilizing, the water spraying from the sprinkler head 7 accelerates the melting of the fertilizer, improves the absorption effect of the fertilizer by the crops, and thus ensures the fertilizing effect of the sprinkler. At the same time, when the sprinkler fails to rotate during operation, the fertilizing plate 14 and the sealing plate 15 will seal the fertilizing frame 13 and the mounting plate 8 to avoid the waste caused by the continuous falling of fertilizer, thereby effectively improving the convenience of using the sprinkler and increasing the overall practicality.
