TECHNICAL FIELD

[0001] The utility model relates to a kind of folding irrigation lance trusses, belong to agricultural irrigation equipment technical field. BACKGROUND

[0002] Rotary or rocker type agricultural irrigation lance, when working, rotate rocker through water flow, to drive spray pipe or spray body to rotate, realize 360 degrees dead angle-free all-terrain coverage irrigation, the range of such sprayer is far, flow range is large, irrigation intensity is lower, uniformity is higher, it is applicable to large-area farmland irrigation.But its irrigation range is approximately circular, cannot cover the edge of square farmland, if cover the edge of farmland, irrigation water will be sprayed out of farmland range and cause waste.

[0003] Now more and more use agricultural irrigation truss, agricultural irrigation truss is a structure specially designed for agricultural irrigation, the length and span of agricultural irrigation truss can be customized according to actual demand, mobile spray irrigation, can cover larger farmland area, through reasonable arrangement of spray head and pipeline, can realize uniform irrigation, improve irrigation efficiency.

[0004] But the existing agricultural irrigation truss, first, cantilever is assembled plug-in type, when irrigating, cannot bypass if encountering obstacle (electric pole etc.) in farmland, only cantilever can be disassembled, after passing through obstacle, reassemble, not only time-consuming and labor-consuming, also affect irrigation efficiency;Second, the existing agricultural irrigation truss coverage is fixed and limited, only cover the land under cantilever, there is certain limitation in coverage range, affected by structural strength, assembly difficulty, cost etc., cantilever cannot be lengthened continuously.

One end of the cantilever main pipe is connected to the frame main pipe, and the other end is connected to the irrigation spray gun. The cantilever main pipe is connected to the cantilever branch pipes via connecting pipes, and the cantilever branch pipes are connected to several cantilever sprinklers. Since the irrigation spray gun and the cantilever sprinklers require different water pressures, if the irrigation spray gun and the cantilever sprinklers are supplied with water from the same pipeline, the water pressure of the irrigation spray gun will be insufficient. Therefore, a separate pipeline is set up for the irrigation spray gun, and another pipeline is used for the several cantilever sprinklers to ensure that the water pressure meets the requirements.

[0010] Preferably, to accommodate folding requirements, the main cantilever pipes of different cantilever arms on the same side are connected by high-pressure rubber joints.

[0015] The folding irrigation spray gun truss described in this utility model can significantly increase the irrigation range and improve irrigation efficiency by introducing an irrigation spray gun.

[0016] The cantilever of this invention adopts a multi-section foldable design, which allows the irrigation truss to fold and avoid obstacles (such as utility poles) and then unfold to continue irrigation, greatly improving the convenience of operation and the adaptability of the equipment.

[0017] This invention, through its pipeline design, ensures that both the irrigation gun and the cantilever nozzle receive the required water pressure, thus avoiding uneven irrigation caused by insufficient water pressure. Attached Figure Description

Detailed Implementation

[0023] The present invention will be further described below with reference to specific embodiments.

[0024] However, the description of this utility model is only a structural or even functional description of the embodiments, and the scope of the present utility model is not limited by the embodiments described herein.

[0025] For example, multiple embodiments may have various modifications and forms, and it should be understood that the scope of this utility model includes equivalents that can realize the technical concept.

[0026] like Figs. 1-4 As shown, this embodiment is achieved through the following technical solution: it includes a movable frame 1 with wheels 13 at the bottom. The frame 1 has cantilever arms on both sides, with several cantilever nozzles 11 on the lower side of the cantilever arms, and irrigation spray guns 8 at the outer ends of the cantilever arms.

[0027] In this embodiment, each cantilever consists of two sections. Each cantilever includes a main cantilever 2 and a secondary cantilever 3. The main cantilever 2 and the frame 1, as well as the secondary cantilever 3 and the main cantilever 2, are connected by hinges. They can be folded and unfolded. If an obstacle is encountered, they can be folded up and unfolded after passing through. After unfolding, they can be fixed together with bolts to prevent bending.

[0028] One end of the inlet pipe 4 is connected to the water supply pipeline via flange 14, and the other end is connected to the main frame pipe 5 mounted on the frame 1. Both ends of the main frame pipe 5 are connected to cantilever water pipes, which supply water to the cantilever sprinklers 11 and irrigation guns 8. The cantilever water pipes include cantilever main pipes and cantilever branch pipes. The cantilever main pipes include a main cantilever main pipe 6 and a secondary cantilever main pipe 7, and the cantilever branch pipes include a main cantilever branch pipe 9 and a secondary cantilever branch pipe 10. The main frame pipe 5 is connected to the main cantilever main pipe 6, and the main cantilever main pipe 6 is connected to the secondary cantilever main pipe 7. The secondary cantilever main pipe 7 is connected to the irrigation gun 8. The main cantilever main pipe 6 is connected to the main cantilever branch pipe 9 via a corresponding connecting pipe 15, and the secondary cantilever main pipe 7 is connected to the secondary cantilever branch pipe 10 via a corresponding connecting pipe 15. Several cantilever sprinklers 11 are connected to the lower side of both the main cantilever branch pipe 9 and the secondary cantilever branch pipe 10. The main frame pipe 5 and the main cantilever pipe 6, as well as the main cantilever pipe 6 and the auxiliary cantilever pipe 7, are all connected by high-pressure rubber joints 16. This water circuit structure is designed because the irrigation spray gun 8 and the cantilever sprinkler head 11 require different water pressures. If the irrigation spray gun 8 and the cantilever sprinkler head 11 are supplied with water from the same pipeline, the water pressure of the irrigation spray gun will be insufficient. Therefore, a separate pipeline (cantilever main pipe) is set up for the irrigation spray gun 8, and several cantilever sprinkler heads 11 use another pipeline (cantilever branch pipe) to ensure that the water pressure meets the requirements.

[0029] In this embodiment, a front sprinkler head 12 is also provided in front of the frame 1 for irrigating the farmland at the corresponding position of the frame 1, leaving no dead corners for irrigation.

[0030] Both the irrigation spray gun 8 and the cantilever nozzle 11 in this embodiment are equipped with switching valves.

[0031] During irrigation, the irrigation nozzle 8 remains stationary (does not rotate) and sprays irrigation water to the side to increase the irrigation area. The irrigation nozzle can be turned on or off as needed, or the spray distance can be adjusted to regulate the coverage area.

[0032] Of course, the above description is only a preferred embodiment of this utility model and should not be considered as limiting the scope of the embodiments of this utility model. This utility model is not limited to the above examples, and all equivalent changes and improvements made by those skilled in the art within the scope of this utility model should be included in the patent coverage of this utility model.
