[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figure 1-3 As shown in the figure, a variable-pitch agricultural drip irrigation device includes a base frame 1. A groove 2 is formed at the top of the base frame 1. Partitions 3 are spaced apart inside the groove 2. A first motor 4 is fixed to the front end of the groove 2. A first screw 5 is connected to the output end of the first motor 4. An adjusting frame 6 is threaded to the outer side of the first screw 5. A bracket 7 is fixed to the top of the adjusting frame 6. A second motor 8 is mounted on the top of the bracket 7. A second screw 9 is connected to the output end of the second motor 8. A guide rod 10 is arranged parallel to the lower part of the second screw 9. The tail end of the guide rod 10 is fixedly installed at the front end of the bracket 7. A sliding frame 11 is slidably installed on the outside of the guide rod 10. A transmission cylinder 12 is welded to the top of the sliding frame 11. A second screw 9 passes through the transmission cylinder 12. A drip irrigation head 13 is installed on one side of the sliding frame 11. A connecting pipe 14 is connected to the outside of the drip irrigation head 13. A partition cylinder 15 passes through the outside of the guide rod 10. A valve 16 is provided on one side of the bracket 7. The valve 16 is connected to the connecting pipe 14. A water delivery pipe 17 is connected to the rear side of the valve 16. A pin 18 is welded to the bottom of the base frame 1.

[0020] The adjusting frame 6 forms a sliding structure between the first screw 5 and the slide groove 2. The adjusting frame 6 is arranged in three sets at equal distances along the horizontal direction of the first screw 5. The partition plate 3 ensures that the three sets of adjusting frames 6 move synchronously with the same spacing, so that the spacing changes too much and affect the drip irrigation. It also facilitates the adjustment of the position of the three sets of drip irrigation mechanisms and ensures the flexibility of equipment adjustment.

[0021] The sliding frame 11 forms a transmission structure with the transmission cylinder 12 and the guide rod 10. There are four sets of sliding frames 11 arranged at intervals along the horizontal direction of the guide rod 10. The transmission cylinder 12 is integrated on the top of the sliding frame 11 on the outer side of the guide rod 10 away from the bracket 7. When the transmission cylinder 12 drives the sliding frame 11 to move back and forth, it can ensure that multiple sets of sliding frames 11 can slide and unfold along the guide rod 10 through the connecting pipe 14, so that the spacing between the sliding frames 11 can be adjusted, which is convenient for adjusting the drip irrigation position and spacing.

[0022] The partition cylinder 15 is slidably mounted on the guide rod 10 between every two sets of sliding frames 11. When the transmission cylinder 12 slides backward, it can control the first set of sliding frames 11 to move backward and push the partition cylinder 15. In this way, it pushes multiple sets of sliding frames 11 on the rear side, thereby ensuring that the spacing between the sliding frames 11 is reduced and that the spacing between the sliding frames 11 is not shortened to too small, thus improving the flexibility of adjustment.

[0023] The connecting pipe 14 is connected to the water supply pipe 17 through the valve 16. Both the water supply pipe 17 and the connecting pipe 14 are made of flexible hoses. The whole system supplies water through the connection with the water supply pipe 17, ensuring the stability of drip irrigation. The use of flexible hoses allows for length allowance, ensuring that the required pipe length is met after equipment adjustment, which is convenient for use and adjustment.

[0024] The base frame 1 has four prongs 18 at the four corners of its bottom, and the prongs 18 are inverted conical in shape. The base frame 1 is fixed in the soil by inserting the prongs 18 at the bottom, so as to stably set up and position it for use.

[0025] Working principle: First, the base frame 1 is fixedly installed by inserting it into the soil through the bottom pins 18, and the usage position is stably set and positioned. At this time, the first motor 4 can be controlled to drive the first screw 5 to rotate, so that the adjustment frame 6 can slide back and forth along the inside of the slide groove 2. The partition plate 3 ensures that the three sets of adjustment frames 6 move synchronously with the same spacing, so that the spacing changes too much and affect the drip irrigation. It also facilitates the adjustment of the position of the three sets of drip irrigation mechanisms, ensuring the flexibility of equipment adjustment and making it easy to adapt to different drip irrigation ranges.

[0026] Next, the second motor 8 at the top of the control bracket 7 can drive the second screw 9 to rotate. The outer thread of the second screw 9 is connected to the transmission cylinder 12, which can drive the transmission cylinder 12 and the first sliding frame 11 at the bottom to move back and forth. The subsequent sliding frames 11 are all connected to the previous sliding frame 11 through the connecting pipe 14. When the transmission cylinder 12 drives the sliding frame 11 to move back and forth, the connecting pipe 14 can ensure that multiple sliding frames 11 slide and unfold along the guide rod 10 for adjustment, so that the spacing between the sliding frames 11 can be adjusted, which is convenient for adjusting the drip irrigation position and spacing. When the transmission cylinder 12 slides backward, it can control the first set of sliding frames 11 to move backward and push the partition cylinder 15, and so on, to push the multiple sets of sliding frames 11 on the rear side, so as to ensure that the spacing between the sliding frames 11 is reduced and that the spacing between the sliding frames 11 is not shortened too much, thus improving the flexibility of adjustment. The whole system is connected to the water supply pipe 17 for water supply, ensuring the stability of drip irrigation. All of them are set with hoses, which can be reserved for length to ensure that the required pipe length after the equipment is adjusted, which is convenient for use and adjustment.
