Description

Technical Field

[0001] This utility model relates to the field of drip irrigation tape laying technology, and in particular to a drip irrigation tape laying device. Background Technology

[0002] Drip irrigation tape is a water-saving irrigation tool that slowly and evenly delivers water and nutrients to the soil near the roots of crops through drippers on the tape. It can accurately supply water to crops according to their water needs, thereby reducing water evaporation and deep water seepage. It is especially suitable for arid and water-scarce areas and for the cultivation of cash crops that require high irrigation precision.

[0003] When laying drip irrigation tape, to ensure its effective operation, the spacing of the tape needs to be adjusted based on differences in crop root distribution and soil permeability. For example, different crops or different planting methods for the same crop will result in different root distributions. If the drip irrigation tape is laid too far from the roots, it will not be able to deliver water to the roots; if it is laid too close, it may waste water or flood the roots. Furthermore, different soil types have different permeability characteristics. For instance, sandy soil permeates quickly but the water does not disperse easily. If the spacing of the drip irrigation tape is too large, the water will not penetrate thoroughly; if the spacing is too small, the water will be overly concentrated, damaging the crop roots or washing away fertilizer.

[0004] To improve the efficiency of drip irrigation tape laying, corresponding laying devices are usually used. However, most existing drip irrigation tape laying devices have a fixed structure and lack a flexible and adjustable spacing adjustment mechanism, making it difficult to adjust the laying spacing of the drip irrigation tape according to the above requirements. This reduces the uniformity of irrigation of crops by the drip irrigation tape, affecting crop growth and yield. Utility Model Content

Detailed Implementation

[0026] The technical solutions and effects of the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0027] Please refer to Figure 1 This utility model provides a drip irrigation tape laying device 10, including a frame component 20, at least two identical drip irrigation components 30, and a guide component 40. One end of the frame component 20 is connected to a traction device, such as a tractor, to move in the field under the pull of the traction device. The bottom position of each drip irrigation component 30 is adjustablely mounted on the top of the frame component 20, and a drip irrigation tape winding device, such as a drip irrigation tape reel, is mounted on it. The guide component 40 is mounted on the lower part of the frame component. The guide component 40 includes an adjustment frame assembly 41 and at least two identical drip irrigation tape guide components 42. The position of each drip irrigation tape guide component 42 is adjustablely mounted on the adjustment frame assembly 41 for winding the drip irrigation tape. The free end of the drip irrigation tape is guided to the ground, and the spacing between adjacent drip irrigation tapes laid on the ground is adjusted by the installation position of each drip irrigation tape guide component 42 on the adjustment frame component 41. Thus, when laying the drip irrigation tape, each drip irrigation tape winding device is installed on each drip irrigation component 30. The free end of each drip irrigation tape winding device contacts the ground under the guidance of a drip irrigation tape guide component 42. Then, by adjusting the installation position of each drip irrigation tape guide component 42 on the adjustment frame component 41, the spacing between adjacent drip irrigation tapes laid on the ground is adjusted, thereby improving the uniformity of irrigation of crops by the drip irrigation tape and reducing the impact of uneven irrigation on crop growth and yield.

[0028] In this embodiment, by setting multiple drip irrigation components 30 with the same structure, it is also convenient to replace the faulty drip irrigation component 30.

[0029] Please refer to Figure 2Furthermore, the frame component 20 includes a main frame assembly 21 and at least two rear wheel assemblies 22 with identical structures. The main frame assembly 21 includes a main frame 211, with at least two first adjustment holes 212 evenly distributed on the top of the main frame 211 for connection to the bottom of each drip irrigation component 30. At least two fixing members 213 are symmetrically provided on the first side of the main frame 211. Each rear wheel assembly 22 includes a rear wheel frame 221 and a rear wheel 222. The first end of the rear wheel frame 221 is rotatably connected to the fixing member 213, and the rear wheel 222 is rotatably mounted on the second end of the rear wheel frame, so that the rear wheel 222 can rotate with the first end of the rear wheel frame 221 as the center, thereby adjusting the height difference between the rear wheel 222 and the main frame 211, so as to adjust the height difference between the main frame 211 and the rear wheel 22 according to different terrains, thereby adjusting the height of the main frame 211 from the ground.

[0030] Please refer to Figure 2 Furthermore, the main frame assembly 21 also includes at least one extension frame 214, on which at least one second adjustment hole 215 is evenly provided for connection to the bottom of each drip irrigation component 30. One end of the extension frame 214 is detachably mounted on one end of the main frame 211 to expand the installation range of each drip irrigation component 30 on the top of the frame assembly 20. At the same time, when transporting the drip irrigation tape laying device 10, the width of the drip irrigation tape laying device 10 can be shortened by removing the extension frame 214 to facilitate transportation.

[0031] Please refer to Figure 2 and Figure 4Furthermore, the frame component 20 also includes at least two adjustment components 23. Each adjustment component 23 includes a first adjustment member 231, a second adjustment member 232, an adjustment rod 233, a handle 234, and a shock-absorbing spring 235.

The bottom end of the adjustment rod 233 is rotatably connected to the second adjustment member 232, and the top end is threadedly connected to the first adjustment member 231, so that the first adjustment member 231 can be moved on the adjustment rod 233 by rotating the adjustment rod 233, thereby adjusting the distance between the first adjustment member 231 and the second adjustment member 232. The handle 234... The adjustment rod 233 is fixedly installed at the top of the adjustment rod 233 to facilitate rotation of the adjustment rod 233; the shock-absorbing spring 235 is sleeved on the adjustment rod 233, and its two ends are fixedly connected to the first adjustment component 231 and the second adjustment component 232 respectively, so as to reduce the vibration of the first adjustment component 231 and the second adjustment component 232 during the movement of the rear wheel 222. Specifically, when the drip irrigation tape laying device 10 moves in the field, the rear wheel 222 will vibrate up and down. This vibration is transmitted to the main frame 211 through the adjustment component 23, causing the main frame 211 to vibrate up and down. The shock-absorbing spring 235 can absorb the vibration energy through its own elastic deformation, reduce the up and down vibration of the main frame 211, and thus improve the stability of the main frame 211.

[0032] In this embodiment, both the first adjusting member 231 and the second adjusting member 232 are rotatably connected by a coupling structure.

[0033] Please refer to Figure 3 Furthermore, the frame component 20 also includes a front wheel assembly 24, which includes a front frame 241, at least two front wheel frames 242, at least two front wheels 243, and a towing frame 244. The first side of the front frame 241 is fixedly connected to the second side of the main frame 211. The first end of each front wheel frame 242 is evenly installed on the second side of the front frame 241, and each front wheel 243 is rotatably installed on the second end of a front wheel frame 242. One end of the towing frame 244 is fixedly installed on the second side of the front frame 241, and the other end is connected to the towing equipment to connect the frame component 20 to the towing equipment.

[0034] In this embodiment, by setting the front wheel 243 and the rear wheel 222, the movement of the irrigation tape laying device in the field can be made more stable.

[0035] Please refer to Figure 3 Furthermore, the front wheel assembly 24 also includes at least one spare bracket 245, the bottom of each spare bracket 245 being evenly fixed to the top surface of the front frame 241, and the top being used to place a spare drip tape winding device for easy replacement of the drip tape winding device.

[0036] Please refer to Figure 5 Furthermore, each drip irrigation component 30 includes a drip irrigation tape frame 31, two fixed shafts 33, and a connecting shaft 34. The bottom of the drip irrigation tape frame 31 has at least two fixed holes 32 evenly distributed for fixed connection with the first adjustment hole 212 or the second adjustment hole 215. One end of each of the two fixed shafts 33 is fixedly connected to the top of the drip irrigation tape frame 31, and the other end is set opposite to each other. The connecting shaft 34 is detachably installed between the two fixed shafts 33, and the drip irrigation tape winding device is rotatably installed on the connecting shaft 34.

[0038] Please refer to Figure 5 Furthermore, the drip irrigation component 30 also includes two connecting sleeves 35, each of which is positionally adjustable on a fixed shaft 33. By adjusting the position of the connecting sleeves 35, the connecting shaft 34 can be connected or separated from the two fixed shafts 33. Specifically, when a new drip irrigation tape winding device needs to be replaced, the connecting sleeve 35 is moved outward to separate the connecting sleeve 35 from the connecting shaft 34, thereby removing the connecting shaft 34 and then removing the drip irrigation tape winding device. After the drip irrigation tape winding device has been replaced, the connecting sleeve 35 is moved inward to engage with the connecting shaft 34, thereby installing the connecting shaft 34 onto the fixed shaft 33.

[0039] In this embodiment, the inner edge of the connecting sleeve 35 and the fixed shaft 33 are both provided with threads, and the position of the connecting sleeve 35 is adjusted by rotation.

[0040] In one embodiment, the inner edge of the connecting sleeve 35 is slidably mounted on the fixed shaft 33.

The pressing member 422 is adjustablely mounted on the second guide shaft 412. The free end of the drip irrigation tape led out by each drip irrigation tape winding device passes through a guide member 421 and a pressing member 422 in sequence and then contacts the ground. The guide member 421 restricts the extension direction of the free end of the drip irrigation tape, and the pressing member 422 restricts the laying position of the drip irrigation tape on the ground.

[0042] In this embodiment, the pressing member 422 fixes the free end of the drip irrigation tape to the ground by pressing.

[0043] In this embodiment, the guide 421 is mounted on the first guide shaft 411. The bottom of the guide 421 has a second threaded hole, and a second bolt is installed in the second threaded hole. The pressure of the second bolt on the first guide shaft 411 is adjusted by rotating the second bolt to fix or loosen the guide 421.

[0044] In this embodiment, the pressure band 422 is mounted on the second guide shaft 412, and the pressure band 422 has a third threaded hole, in which a third bolt is installed. The pressure of the third bolt on the second guide shaft 412 is adjusted by rotating the third bolt to fix or loosen the pressure band 422.

[0045] In this embodiment, the guide member 421 is provided with a guide ring, and the pressing member 422 is provided with a pressing wheel.
