Description

Technical Field

[0001] This utility model belongs to the field of irrigation technology, specifically relating to a water-saving irrigation device for farmland. Background Technology

[0002] Water-saving irrigation aims to maximize yield or revenue with minimal water consumption, that is, to maximize crop yield and output value per unit of irrigation water. The main measures include: canal seepage prevention, low-pressure pipe irrigation, sprinkler irrigation, micro-irrigation, and irrigation management systems.

[0003] For example, patent application number CN202022565460.2 discloses a water-saving irrigation device for farmland, which can greatly reduce water loss and waste, and also save farmers' irrigation time. Although this solution can reduce water loss and waste and save farmers' irrigation time, the height of its sprinkler cannot be adjusted. If the sprinkler height is too high, too much water will evaporate into the air during the sprinkler process.

[0004] In view of this, the inventor conducted in-depth research on the aforementioned deficiencies in the prior art, which led to the creation of this case. Utility Model Content

[0005] The purpose of this invention is to provide a water-saving irrigation device for farmland, which solves the problem that the sprinkler height cannot be adjusted in the existing technology.

[0006] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0007] A water-saving irrigation device for farmland includes a water tank, a water pump, several spray components, and a water supply pipe connected between the spray components. The spray component includes an installation cylinder that can be inserted into the soil and a spray pipe movably disposed within the installation cylinder. The bottom of the spray pipe is provided with a water inlet head that slides in contact with the inner wall of the installation cylinder, and the top is provided with a plurality of spray nozzles arranged in a ring array. The upper part of the installation cylinder is provided with a clamping component for fixing the spray pipe. The side wall of the installation cylinder is provided with two connecting nozzles that connect to the water supply pipe, and a fixing post is formed at the bottom of the installation cylinder.

[0008] Furthermore, a filter plug is fitted inside the water inlet head, and the filter plug has several filter holes; the inner diameter of the water inlet head gradually decreases from bottom to top. The filter plug can filter the water and prevent the spray nozzle from becoming clogged.

[0009] Furthermore, the clamping assembly includes two symmetrically arranged clamping plates and a locking screw. One end of the locking screw is provided with a connecting block that is rotatably connected to the clamping plate, and the other end is provided with a knob. The side wall of the mounting cylinder is provided with a mounting tube that is threadedly engaged with the locking screw. The spray pipe can be quickly fixed and locked by the locking screw and the clamping plates.

[0010] Furthermore, the clamping plate is arc-shaped, and its inner diameter is the same as the outer diameter of the spray pipe. The arc-shaped clamping plate can increase the locking effect.

[0011] Furthermore, a sealing ring is fitted onto the outer wall of the inlet head. The sealing ring improves the seal between the inlet head and the mounting cylinder.

[0012] Furthermore, the mounting cylinder is also equipped with a sealing mechanism for sealing the connecting nozzle. The sealing mechanism includes a sealing ball and a spring. The diameter of the sealing ball is greater than or equal to the inner diameter of the connecting nozzle. An mounting plate is provided on the inner bottom wall of the mounting cylinder. One end of the spring is fixedly connected to the mounting plate, and the other end is fixedly connected to the sealing ball. The sealing mechanism can seal the connecting nozzle of the mounting cylinder.

[0013] Furthermore, both ends of the water supply pipe are provided with connectors threaded to the connecting nozzles, and each connector is fixed with a push rod that can push the sealing ball inward. When connecting the water supply pipe, the push rod can be used to push the sealing ball inward, thereby enabling the water supply pipe to quickly connect with the installation cylinder.

[0014] With the above structure, the farmland water-saving irrigation device of this utility model, compared with the prior art, movably installs the spray pipe in the installation cylinder. During use, the spray pipe can be slid up and down to adjust the spray height. After the height is adjusted, the spray pipe can be fixed by the clamping component. Attached Figure Description

It should be noted that similar or identical parts are referred to by the same reference numerals in the drawings or description. Implementations not shown or described in the drawings are forms known to those skilled in the art. Furthermore, directional terms mentioned in the embodiments, such as "up," "down," "top," "bottom," "left," "right," "front," and "back," are only for reference to the directions in the drawings and are not intended to limit the scope of protection of the present invention.

[0027] like Figures 1-9As shown, this utility model relates to a water-saving irrigation device for farmland, including a water tank 1, a water pump 2, several spray components 3, and a water delivery pipe 4 connecting the spray components 3. The water tank 1 and the water pump 2 are connected by a flexible hose. The water pump 2 draws water from the water tank 1 and delivers it to each spray component 3 for spraying. Each spray component 3 includes an installation cylinder 31 that can be inserted into the soil and a spray pipe 32 that is movably installed inside the installation cylinder 31. A fixing post 312 is formed at the bottom of the installation cylinder 31. The fixing post 312 is conical. The bottom of the spray pipe 32 is provided with a sliding contact with the inner wall of the installation cylinder 31. The water inlet head 321 has multiple spray nozzles 322 arranged in a ring array on its top. Two connecting nozzles 311 connected to the water supply pipe 4 are also provided on the side wall of the mounting cylinder 31. During use, water first enters the mounting cylinder 31 and then enters the spray pipe 32 from the mounting cylinder 31. In order to enhance the sealing between the water inlet head 321 and the mounting cylinder 31, a sealing ring 33 is fitted on the outer wall of the water inlet head 321. Multiple sealing rings 33 can be provided. In addition, a clamping assembly 34 is provided on the upper part of the mounting cylinder 31 to fix the spray pipe 32. The spray pipe 32 is fixed by the clamping assembly 34.

[0028] In this embodiment, to prevent the spray nozzle 322 from being clogged by impurities in the water, a filter plug 35 is installed inside the water inlet head 321, and a plurality of filter holes 351 are formed on the filter plug 35. The inner diameter of the water inlet head 321 gradually decreases from bottom to top. A rubber pad can be covered on one side of the outer wall of the filter plug 35 to enhance the friction between it and the water inlet head 321. In addition, after a period of use, the filter plug 35 can be removed from the connector 41 for cleaning or replacement.

[0029] In this embodiment, the clamping assembly 34 includes two symmetrically arranged clamping plates 341 and a locking screw 342.

The side wall of the mounting cylinder 31 is provided with a mounting tube 313 that is threadedly engaged with the locking screw 342. When it is necessary to adjust the height of the spray pipe 32, simply rotate the locking screw 342 to disengage the clamping plate 341 from the spray pipe 32, and then manually adjust the height of the spray pipe 32. After adjustment, rotate the locking screw 342 in the opposite direction to clamp the spray pipe 32 with the clamping plate 341. To enable the clamping plate 341 to better clamp the spray pipe 32, the clamping plate 341 can be set in an arc shape, and the inner diameter of the clamping plate 341 is the same as the outer diameter of the spray pipe 32.

[0030] In this embodiment, the mounting cylinder 31 is further provided with a sealing mechanism 36 for sealing the connecting nozzle 311. The sealing mechanism 36 includes a sealing ball 361 and a spring 362. The sealing ball 361 can be made of rubber, and its diameter is greater than or equal to the inner diameter of the connecting nozzle 311. The inner bottom wall of the mounting cylinder 31 is provided with a mounting plate 314. One end of the spring 362 is fixedly connected to the mounting plate 314, and the other end is fixedly connected to the sealing ball 361. Connecting heads 41 that are threadedly connected to the connecting nozzle 311 are provided at both ends of the water pipe 4. A push rod 411 that can push the sealing ball 361 inward is fixedly provided inside the connecting head 41. When connecting the water pipe 4, the sealing ball 361 can be pushed inward by the push rod 411, thereby quickly connecting the water pipe 4 and the mounting cylinder 31.

[0031] The method of using this utility model is as follows: First, insert the sprinkler assembly 3 into the soil in sequence and adjust the height of the sprinkler pipe 32. Then, connect the water supply pipe 4 to the mounting cylinder 31 of the sprinkler assembly 3. During the connection process, the sealing ball 361 in the connecting nozzle 311 can be pushed out by the top rod 411 in the connector 41, so that the water supply pipe 4 is connected to the mounting cylinder 31. Finally, start the water pump 2 to pump the water in the water tank 1 into each sprinkler assembly 3 to irrigate the crops.

[0032] The above provides a detailed description of a water-saving irrigation device for farmland provided by this utility model. The specific embodiments are described only to aid in understanding the method and core concept of this utility model.
