Description

A sprinkler irrigation device for rice seedling raising Technical Field

[0001] This utility model relates to a sprinkler irrigation device for rice seedling cultivation, belonging to the field of agricultural machinery technology. Background Technology

[0002] During the rice seedling raising process, irrigation is generally required for the seedlings. The existing seedling irrigation generally uses a main pipeline to bring water to the edge of the field and then branches out into the field. The water is then dripped onto the soil next to the seedlings through the branch pipelines via energy-saving drip irrigation heads. This method has a huge water-saving advantage compared with flood irrigation and sprinkler irrigation.

[0003] For example, the authorized announcement number is CN211671741U, and the patent name is: A Chinese authorized utility model patent for an energy-saving drip irrigation head that can be quickly disassembled and installed for agricultural irrigation. An installation plate is fixedly installed on the irrigation pipe, and the drip irrigation head body is installed on the installation plate. Two fixing grooves are opened on the top of the installation plate, and clamping plates are slidably installed in both fixing grooves. Both clamping plates are in contact with the drip irrigation head body. The same fixing hole is opened on the inner wall of the side of the two fixing grooves that are close to each other. A toothed rack is slidably installed on the inner walls of both sides of the fixing hole. The ends of the two toothed racks that are far apart from each other are fixedly installed on the corresponding two clamping plates for fixation.

[0004] While the aforementioned patent can fix the drip irrigation head body, it has the following problems when used:

[0005] The fixing device for the drip irrigation head body in the aforementioned patent uses a variety of parts such as a mounting plate, a rack and pinion, and a compression spring, resulting in a relatively complex structure for the fixing device. Furthermore, existing fixing devices are generally small in size, making repairs quite troublesome once damaged.

[0006] 2. In actual use, hundreds or thousands of drip irrigation heads may need to be installed on a single irrigation pipe. If existing fixing devices are used for all of them, the cost will be high and it will not be suitable for large-scale use. Summary of the Invention

[0007] The technical problem to be solved by this utility model is to provide a sprinkler irrigation device for seedling cultivation, so as to solve the problems faced in the industry.

[0028] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments:

[0029] As shown in Figures 1 to 10, a sprinkler irrigation device for rice seedling cultivation includes a movable support 1, an electrical box 2 mounted on the movable support 1, and multiple ball valves 3 mounted on the movable support 1. A main water inlet pipe 4 is mounted on the side of the movable support 1, and multiple branch water inlet pipes 5 are mounted on the main water inlet pipe 4. One end of each branch water inlet pipe 5 is connected to the water inlet of the ball valve 3, and a branch water outlet pipe is connected to the water outlet of the ball valve 3. A spray pipe 6 is connected to the branch water outlet pipe, and multiple drainage holes 601 are provided on the surface of the spray pipe 6. An intermediate transition pipe 7 is provided in each drainage hole 601. An upper positioning seat 8 and a lower positioning seat 9 are respectively provided on the outer surface of the intermediate transition pipe 7 from top to bottom. An intermediate gap 10 is provided between the upper positioning seat 8 and the lower positioning seat 9. A sprinkler head 11 made of rubber is also sleeved on the intermediate transition pipe 7.

[0030] As shown in Figure 8, Figure 8 is an exploded view of the upper positioning seat, the lower positioning seat, and the intermediate transition tube. The upper positioning seat 8 includes an upper body 801, and an upper insertion hole 802 is provided in the middle of the upper body 801. The intermediate transition tube 7 is inserted into the upper insertion hole 802. The outer side of the upper body 801 is provided with a rounded corner 803. The rounded corner 803 not only facilitates the installation of the sprinkler head 11, but also prevents the sharp corner from scratching the sprinkler head 11.

[0031] In this patent, the lower positioning seat 9 has a circular structure, and a lower insertion hole 901 is provided in the middle of the lower positioning seat 9. The lower positioning seat 9 is sleeved and fixed on the intermediate transition tube 7 through the lower insertion hole 901.

[0032] In this patent, a sprinkler head 11 is provided. The sprinkler head 11 includes a hollow, circular sprinkler body 1101 and a sprinkler connector 1102 located at the bottom of the sprinkler body 1101. A central water inlet hole 1103 is provided in the center of the sprinkler connector 1102. The sprinkler connector 1102 is located in the central gap 10. The sprinkler connector 1102 and the central gap 10 are interference fit. Since the sprinkler head 11 is made of rubber, the elasticity of the rubber can be utilized to facilitate the placement of the sprinkler connector 1102 on the sprinkler head 11 into the central gap 10.

[0033] In order to spray irrigation water, a plurality of spray holes 1104 are further provided on the surface of the sprinkler body 1101.

[0034] In order to input irrigation water into the sprinkler pipe 6, a water pump 401 is installed on the main water inlet pipe 4. The water to be irrigated is input into the sprinkler pipe 6 by the water pump 401 and sprayed out from the spray hole 1104.

[0035] To facilitate the movement of the entire device, the bottom of the movable support 1 is further provided with multiple movable rollers 101.

[0036] Before use, multiple drainage holes 601 are first set on the spray pipe 6, and the drainage holes 601 penetrate from the outer surface of the spray pipe 6 to the inside. One end of the intermediate transition pipe 7 is inserted into the drainage hole 601, and the intermediate transition pipe 7 is welded to the spray pipe 6. The lower positioning seat 9 is sleeved on the intermediate transition pipe 7 at the set position through the lower insertion hole 901, and the lower positioning seat 9 is fixed together with the intermediate transition pipe 7. The upper positioning seat 8 is sleeved on the intermediate transition pipe 7 through the upper insertion hole 802. The upper surface of the upper positioning seat 8 is flush with the upper surface of the intermediate transition pipe 7. At the same time, the upper positioning seat 8 is fixed to the intermediate transition pipe 7. In the above process, an intermediate gap 10 is formed between the lower surface of the upper positioning seat 8 and the upper surface of the lower positioning seat 9. The height of the intermediate gap 10 is less than the thickness of the spray connection seat 1102, and the spray connection seat 1102 and the intermediate gap 10 are interference fit.

[0037] The sprinkler head 11 is fitted onto the upper positioning seat 8, and the sprinkler connector 1102 on the sprinkler head 11 is placed into the intermediate gap 10. Since the height of the intermediate gap 10 is less than the thickness of the sprinkler connector 1102, the sprinkler connector 1102 and the intermediate gap 10 are interference fit. Utilizing the elasticity of the rubber, the sprinkler connector 1102 is inserted into the intermediate gap 10, so that the sprinkler connector 1102 fills the entire intermediate gap 10, which not only plays a fixing role, but also prevents water leakage from the sprinkler connector 1102.

[0038] Connect one end of the spray pipe 6 to one end of the branch water pipe, seal the other end of the spray pipe 6, connect the other end of the branch water pipe to the outlet of the ball valve 3, and connect the inlet pipe 5 to the inlet of the ball valve.

[0039] When in use, the water pump 401 is started, and the water pump 401 delivers the water to be irrigated to the main water inlet pipe 4, and from the main water inlet pipe 4 into the branch water inlet pipe 5. By opening and closing the ball valve 3, the irrigation water is input into the sprinkler pipe 6 and sprayed out from the spray holes 1104 of multiple sprinkler heads 11, thereby achieving the purpose of irrigation. During the irrigation process, the pressure of the irrigation water in the sprinkler pipe 6 can be adjusted by the opening and closing angle of the ball valve 3, thereby adjusting the distance of the irrigation water sprayed from the spray holes 1104, so as to irrigate the seedlings in different positions and improve the irrigation efficiency.

[0040] In this patent, since the sprinkler head 11 is made of rubber, it has a certain elasticity. When a sprinkler head 11 needs to be replaced, the sprinkler connection seat 1102 of the sprinkler head 11 can be pulled out from the middle gap 10, thereby improving the replacement efficiency. In addition, the structure of this patent is relatively simple, which solves the problem that the sprinkler head fixing structure is relatively complex and costly in the prior art.

[0041] The electrical box 2 of this patent is also equipped with multiple timed start-stop solenoid valves. The ball valve 3 can be opened at regular intervals by the timed start-stop solenoid valves, thereby improving the automation of irrigation.

[0042] It should be emphasized that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
