[0002] Corn is widely planted in tropical and temperate regions all over the world. It has high nutritional value and is an excellent food crop. It is also one of the indispensable raw materials for food, medical and health care, light industry, chemical industry, etc. During the corn planting process, drip irrigation belts are needed to complete the active drip irrigation operation for corn to ensure the stable growth of corn.

[0003] At present, when the drip irrigation belts used for corn planting are in use, limited by the length of the drip irrigation area and other factors, the length of the drip irrigation belt needs to be adjusted according to the length of the planting area. Therefore, the drip irrigation belts often need to be connected in series to extend the overall length.

Specific embodiments

[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0025] The present utility model provides a technical solution: As Figures 1 to 6 shown, in this embodiment, a drip irrigation tape series connection structure includes two connecting pipes 1, and both two connecting pipes 1 are of a hollow structure. One end of one connecting pipe 1 is connected with a first drip irrigation tape 2, one end of the other connecting pipe 1 is connected with a second drip irrigation tape 3, the other end of one connecting pipe 1 is recessed inward to form an annular area 4, an internal thread 5 is provided on the inner wall of the annular area 4, the other end of the other connecting pipe 1 protrudes outward to form an annular part 6, and a first external thread 7 is provided on the outer wall of the annular part 6. The annular part 6 is restricted in the annular area 4 through the cooperation of the internal thread 5 and the first external thread 7;

[0026] Pressing mechanisms are added to both ends of the two connecting pipes 1 away from each other. The pressing actions of the two connecting pipes 1 with the first drip irrigation tape 2 and the second drip irrigation tape 3 are respectively completed through the two pressing mechanisms, and an adjusting mechanism is added to one of the connecting pipes 1. The flow rate in the two connecting pipes 1 is controlled through the adjusting mechanism.

[0027] As Figures 4 to 6As shown in the figure, both pressing mechanisms include connecting sleeves 8 connected and installed on one side of the two connecting pipes 1. The two connecting sleeves 8 are provided with conical sleeves 9 towards one end of the two connecting pipes 1. The connecting sleeves 8 and conical sleeves 9 on the two pressing mechanisms are respectively connected to the first drip irrigation tape 2 and the second drip irrigation tape 3. The two conical sleeves 9 are respectively used to complete the connection between the two connecting sleeves 8 and the two connecting pipes 1. Second external threads 10 are provided on the outer walls of the two connecting pipes 1;

[0028] It should be noted that when pressing the first drip irrigation tape 2 and the second drip irrigation tape 3: by providing a pressing mechanism, first, one end of the first drip irrigation tape 2 and the second drip irrigation tape 3 is correspondingly sleeved outside the connecting sleeve 8, and then the first drip irrigation tape 2 and the second drip irrigation tape 3 are continuously pushed, so that the front ends of the first drip irrigation tape 2 and the second drip irrigation tape 3 are gradually sleeved on the expanded diameter end formed by the conical sleeve 9, thereby completing the expansion restriction of the first drip irrigation tape 2 and the second drip irrigation tape 3. Under normal conditions, the pressing ring 13 is separated from the connecting sleeve 8, so that the first drip irrigation tape 2 and the second drip irrigation tape 3 are conducive to the preliminary sleeving work. After the sleeving is completed, only the threaded collar 14 needs to be rotated. Under the guidance of the second external thread 10, the two sliding members 12 are pushed to move on the slideway 11, so that the pressing ring 13 approaches the conical sleeve 9. The initial pressing of the first drip irrigation tape 2 and the second drip irrigation tape 3 is completed through the gap formed between the pressing ring 13 and the connecting sleeve 8. At the same time, with the cooperation of the structural characteristics of the conical groove 15 on the pressing ring 13 and the conical sleeve 9, the stable pressing of the first drip irrigation tape 2 and the second drip irrigation tape 3 is completed, so that the first drip irrigation tape 2 and the second drip irrigation tape 3 obtain a stable state, avoid falling off, and are convenient for installation and disassembly. At the same time, a plurality of friction members 17 are arranged in the conical groove 15, and the plurality of friction members 17 are in frictional contact with the first drip irrigation tape 2 and the second drip irrigation tape 3, so that the pressing ring 13 and the first drip irrigation tape 2 and the second drip irrigation tape 3 obtain a stable pressing state. The static friction generated by contacting the plurality of friction members 17 further improves the pressing effect. At the same time, the pushing spring 18 is used to provide a thrust for the friction members 17, so that the friction members 17 are in stable contact with the first drip irrigation tape 2 and the second drip irrigation tape 3, and the wear amount of the friction members 17 can be compensated;

[0029] Among them, sliding grooves 11 are opened at the top and bottom of one end of the two connecting pipes 1 close to the connecting sleeve 8. Sliding members 12 are slidably engaged in the two sliding grooves 11. Pressing ring members 13 are installed at the tails of the two sliding members 12. Threaded collar rings 14 are screwed onto the second external threads 10 outside the two connecting pipes 1. One side of the threaded collar ring 14 is slidably connected to the two sliding members 12. An annular track matching the two sliding members 12 is opened on the side wall of the threaded collar ring 14. Inner walls of one ends of the pressing ring members 13 facing the connecting pipes 1 are provided with tapered grooves 15. The tapered grooves 15 are arranged in cooperation with the tapered sleeves 9. The pressing action is completed through the cooperation of the tapered grooves 15 and the tapered sleeves 9. And the pressing ring members 13 are arranged at intervals from the connecting sleeve 8. A plurality of grooves 16 are arranged in a circular array on the inner wall of the tapered groove 15. Friction members 17 are slidably installed in the plurality of grooves 16. Sliding areas matching the friction members 17 are opened in the grooves 16. Tops of the friction members 17 can extend out of the grooves 16. A pushing spring 18 is arranged between the bottoms of the friction members 17 and the grooves 16. The friction members 17 are driven by the pushing spring 18 to extend out of the grooves 16. The friction members 17 are made of friction materials.

[0030] As Figure 3 shown, the adjusting mechanism includes an open slot 19 opened on one of the connecting pipes 1. A restricting plate 20 is hermetically inserted into the open slot 19. The flow rate in the connecting pipe 1 is adjusted through the restricting plate 20. An L-shaped seat 21 is installed on the connecting pipe 1 on one side of the restricting plate 20. A lifting screw rod 22 is screwed through the L-shaped seat 21. The bottom of the lifting screw rod 22 is rotatably connected to the top of the restricting plate 20. And a hand wheel is installed at the top of the lifting screw rod 22.

[0031] It is worth noting that when adjusting the flow rate in the connecting pipe 1: by providing the adjusting mechanism, only the hand wheel needs to be correspondingly rotated to drive the lifting screw rod 22 to complete the lifting action on the L-shaped seat 21, and the restricting plate 20 is linked to move up and down in the connecting pipe 1, so as to actively control the flow rate in the connecting pipe 1, which is beneficial to the drip irrigation work, convenient for the staff to operate and use, and the adjustment is convenient and fast.

[0032] The utility model provides a series connection structure of drip irrigation tapes. The specific working principle is as follows: First, two connecting pipes 1 are initially connected through an annular member 6 and an annular region 4. The two connecting pipes 1 are designed to be separable, so that the damaged parts can be separately replaced later, and it is also convenient to carry. Subsequently, the two connecting pipes 1 are connected into a whole through the cooperation of a first external thread 7 and an internal thread 5, which is beneficial to the subsequent series connection of the first drip irrigation tape 2 and the second drip irrigation tape 3. Then, the first drip irrigation tape 2 and the second drip irrigation tape 3 are respectively inserted into the pressing mechanisms at both ends of the two connecting pipes 1 to complete the preliminary limiting and fixing. Subsequently, the pressing mechanisms complete the stable pressing actions of the two connecting pipes 1 with the first drip irrigation tape 2 and the second drip irrigation tape 3, so that the first drip irrigation tape 2 and the second drip irrigation tape 3 are connected in series, which is beneficial to the subsequent drip irrigation work. At the same time, the pressing mechanisms make the connection between the two connecting pipes 1 and the first drip irrigation tape 2 and the second drip irrigation tape 3 stable, easy to disassemble and install, reduce the operation difficulty of the staff, and an adjusting mechanism is added to one of the connecting pipes 1. The adjusting mechanism is used to actively adjust the flow rate in the connecting pipe 1, which is convenient for the staff to control the drip irrigation speed of the first drip irrigation tape 2 and the second drip irrigation tape 3, so that the overall drip irrigation work proceeds smoothly and the drip irrigation accuracy is improved.
