Description

Technical Field

[0001] The utility model relates to an onion planting irrigation device. Background Art

[0002] Irrigation is required during the onion planting process. The existing irrigation method is spray irrigation. The mainstream method is to lay pipes on the ground and connect sprinklers in series on the pipes for spraying. The advantage of this spraying method is that the pipes can be quickly removed when the onions are harvested automatically later.

[0003] Another spraying method is to pre-bury the pipes. The pre-buried depth needs to be greater than the planting depth of the onions, and the nozzles are exposed upwards. When the onions are collected automatically in the later stage, there is a certain chance of damage to the pipes and nozzles.

[0004] With the first type of pipe arrangement, when water flows through, the pipes will shift and the spraying position cannot be fixed, resulting in insufficient irrigation in some locations.

[0005] Based on the above problems, we designed an onion planting irrigation device which can be quickly disassembled and assembled to facilitate onion watering. Utility Model Content

[0006] The technical problem to be solved by the utility model is to provide an onion planting irrigation device which can be quickly disassembled and quickly assembled and is convenient for watering onions.

[0025] like Figure 1 An onion planting irrigation device shown includes a pipeline 1, both ends of the pipeline 1 are connected, and an annular groove 101 is processed near the two ends of the outer wall of the pipeline 1. An insertion shaft 102 is provided at the bottom of the pipeline 1, and the insertion shaft 102 is inserted into the soil layer. A vertical pipe 103 is installed at the upper end of the pipeline 1, and the vertical pipe 103 is connected to the pipeline 1. A valve 104 is installed at the upper end of the vertical pipe 103, and a water outlet device 2 is installed at the upper end of the valve 104.

[0026] See also Figure 1 As shown, a threaded portion is processed on the outer wall of the pipe 1 near the slot 101, and a tightening sleeve 3333 is fitted through the threaded portion. The interior of the tightening sleeve 3333 has an inner conical surface.

[0027] When the water pipe is connected to the two ends of the pipeline 1, the inner conical surface is used to press the water pipe into the clamping groove 101 by screwing the tightening sleeve 3333 to prevent it from loosening. The step of fixing with a clamp is omitted, making the arrangement of the irrigation device faster.

[0028] See also Figure 1 As shown, a spiral sheet 122 is disposed on the outside of the insertion shaft 102 .

[0029] The spiral blade 122 is used to facilitate the insertion of the shaft 102 into the soil layer by rotation for hard ground, and the screw-in and fixed method has higher stability.

[0030] See also Figure 2 As shown, the water outlet device 2 includes a shell 201, the lower end of the shell 201 is detachably fitted with a shell cover 202, a water inlet pipe 203 is provided at the bottom of the shell cover 202, the water inlet pipe 203 is connected to the valve 104, and a plurality of water spray holes 204 are distributed in an annular manner on the outer wall of the shell 201.

[0031] In the above technical solution, the shell 201 and the shell cover 202 are detachable structures, which is convenient for maintenance when the water spray hole 204 is dirty and blocked.

[0032] See also Figure 2 As shown, a partition plate 211 is sandwiched between the shell 201 and the shell cover 202 , and filter holes 212 are distributed on the plate surface of the partition plate 211 .

[0033] Some irrigation uses river water, which contains relatively more impurities. The above-mentioned partition 211 is combined with the filter hole 212 to block some impurities.

[0034] See also Figure 2 and Figure 3As shown, a support rod 3 is arranged at the axis of the partition 211, and a base 31 is arranged at the upper end of the support rod 3. An assembly hole corresponding to the water spray hole 204 is arranged in an annular manner on the outer wall of the base 31, and a ejector pin 32 is slidably assembled in the assembly hole. The end of the ejector pin 32 located inside the base 31 is spherically transitioned, and the end of the ejector pin 32 located outside the base 31 is inserted into the water spray hole 204 after a conical transition. A retaining ring 33 is arranged near the spherical transition position of the ejector pin 32, and a spring 34 is arranged on the ejector pin 32. 34 acts between the base 31 and the retaining ring 33, a screw rod 221 is screwed into the top of the shell 201, and a movable rod 222 is detachably mounted at the lower end of the screw rod 221, a sealing ring 223 is provided between the movable rod 222 and the shell 201, and a conical action end 224 is provided at the lower end of the movable rod 222, and the action end 224 is coaxial with the base 31. After the action end 224 is inserted into the base 31, it acts on the ejector pin 32, and as the action end 224 moves downward, the ejector pin 32 is ejected outward.

[0035] In the above technical solution, the position of the ejector pin 32 can be adjusted by rotating the action end 224 upward or downward. The change in the position of the ejector pin 32 can change the water spraying section of the water spray hole 204. When the flow rate of the valve 104 is fixed, the reduction of the water spraying section can increase the range of the water spraying.

[0036] The ejection of the ejector pin 32 can also clear the water spray hole 204 .

[0037] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
