[0002] The drip irrigation pipe is an important irrigator in the drip irrigation system. According to the water requirement of crops, through the low-pressure pipeline system and the water emitters installed on the lateral pipe, water and nutrients required by crops are dripped into the soil in the root zone of crops drop by drop, evenly and slowly, so that the leakage and loss of water and fertilizer are reduced to the lowest limit, the production cost is reduced, and the resource utilization rate is improved.

[0003] When operators test the tensile property of the polyethylene drip irrigation pipe, they often use inspection devices to detect the stretch ratio of the drip irrigation pipe. In the actual use process of the existing detection equipment, although it has basic detection functions, the existing detection equipment generally uses manual methods to test the stretch ratio of the polyethylene drip irrigation pipe, which makes the detection result inaccurate and also increases the labor intensity of the operators. Therefore, it needs to be improved. Summary of the Utility Model

Specific embodiments

[0025] 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. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] As Figures 1 to 6 shown, the present utility model provides a polyethylene drip irrigation pipe inspection device, including:

[0027] A bed body 1, and a support column 2 is fixedly connected to the lower surface of the bed body 1;

[0028] A stretching mechanism, which is arranged inside the bed body 1;

[0029] Among them, the stretching mechanism includes a drive motor 3, the drive motor 3 is fixedly installed in the middle of the lower surface of the bed body 1, the top end of the drive motor 3 penetrates through the bed body 1 and extends to the inner surface of the bed body 1, and the other end of the output shaft of the drive motor 3 is fixedly sleeved with a drive round shaft 4 located inside the bed body 1. A rotating rod 5 is fixedly sleeved on the outer surface of the drive round shaft 4. One end of each of the two rotating rods 5 is hinged with a first connecting rod 6, and the other end of the first connecting rod 6 is hinged with a first moving block 7. The number of the first moving blocks 7 is two, and the positions of the two first moving blocks 7 are symmetrical about the left and right of the bed body 1. When the rotating rod 5 rotates, the first connecting rod 6 drives the first moving block 7 to move as a whole.

[0030] When the drive motor 3 operates, the drive shaft 4 drives the rotating rod 5 to start rotating. At this time, both ends of the rotating rod 5 drive the first connecting rods 6, causing the two first connecting rods 6 to start rotating around the two ends of the rotating rod 5 as the axes. At the same time, the other ends of the first connecting rods 6 drive the first moving blocks 7, causing the two first moving blocks 7 to start moving.

[0031] Wherein, the outer surfaces of the two first moving blocks 7 are both movably connected with cover plates 8, and the lower surfaces of the cover plates 8 are fixedly connected with the upper surface of the bed body 1.

[0032] Due to the design of the inner surface of the cover plate 8, it is ensured that the two first moving blocks 7 as a whole can move away from each other along the inner surface of the cover plate 8.

[0033] Wherein, the upper surfaces of the two first moving blocks 7 are both fixedly connected with hollow boxes 9. The number of the hollow boxes 9 is two, and the two hollow boxes 9 have the same size.

[0034] When the two first moving blocks 7 start to move, the two hollow boxes 9 as a whole will move along with the two first moving blocks 7 respectively.

[0035] Wherein, sliding grooves 10 are formed on the outer surfaces of the two hollow boxes 9, and the upper and lower sides of the inner surfaces of the sliding grooves 10 are both movably connected with second moving blocks 11.

[0036] Due to the design of the sliding grooves 10, the second moving blocks 11 can slide up and down along the inner surfaces of the sliding grooves 10.

[0037] Wherein, the outer surfaces of the second moving blocks 11 are fixedly connected with clamping plates 12 located between the two hollow boxes 9. The number of the clamping plates 12 is four, and the four clamping plates 12 have the same size.

[0038] The four clamping plates 12 can clamp the two ends of the drip irrigation pipe to ensure that the drip irrigation pipe will not become loose during stretching.

[0039] Wherein, the outer surfaces of the second moving blocks 11 are hinged with second connecting rods 13 located inside the hollow boxes 9, and the other ends of the second connecting rods 13 are hinged with hinge plates 14.

[0040] When the hinge plate 14 moves to the left, the second connecting rod 13 will start to rotate around the right end of the hinge plate 14 as the axis. At the same time, the other end of the second connecting rod 13 will pull the second moving block 11, causing the four second moving blocks 11 as a whole to start moving towards each other along the inner surfaces of the sliding grooves 10.

[0041] Wherein, the left end of the hinge plate 14 is fixedly connected with a pneumatic cylinder 15. The pneumatic cylinder 15 is located inside the hollow box 9, and the left end of the pneumatic cylinder 15 is fixedly connected with the inner surface of the hollow box 9.

[0042] When the pneumatic cylinder 15 operates, the pneumatic cylinder 15 will drive the hinge plate 14 and cause the hinge plate 14 to start moving to the left.

[0043] The working principle and usage process of the present utility model:

[0044] First, the operator places the drip irrigation pipe between the four clamping plates 12, and then the operator starts the pneumatic cylinder 15. As the pneumatic cylinder 15 operates, the hinge plate 14 will start moving to the left under the drive of the pneumatic cylinder 15, and the movement of the hinge plate 14 will drive the second connecting rod 13 and cause it to start rotating. At this time, the other end of the second connecting rod 13 will drive the second moving block 11, causing the four second moving blocks 11 as a whole to start moving towards each other under the limitation of the sliding groove 10. This will cause the four clamping plates 12 to gradually approach the outer surface of the drip irrigation pipe. When the four clamping plates 12 clamp the outer surface of the drip irrigation pipe, the four clamping plates 12 will fix the drip irrigation pipe.

[0045] After the fixation of the drip irrigation pipe is completed, the operator starts the driving motor 3. As the driving motor 3 operates, the driving round shaft 4 and the rotating rod 5 will start to rotate, and the rotation of the rotating rod 5 will drive the two first connecting rods 6, causing the two first connecting rods 6 to start rotating respectively with the two ends of the rotating rod 5 as the axes. The other ends of the two first connecting rods 6 will drive the two first moving blocks 7, causing the two first moving blocks 7 as a whole to start moving away from each other under the limitation of the inner surface of the cover plate 8. This will cause the drip irrigation pipe fixed between the four clamping plates 12 to be gradually stretched, and finally obtain the stretching ratio data of the drip irrigation pipe under the condition of a predetermined tensile force.
