Description

Technical Field

[0001] The utility model relates to the field of irrigation, and particularly relates to an automatic sprinkler for irrigation with an adjustable irrigation range. Background Technique

[0002] In garden greening irrigation, water is sprayed onto green plants and the soil through water pipes and spraying devices for water replenishment of the green plants and irrigation of the soil. The core part of the irrigation sprinkler, especially the lawn watering sprinkler, is the nozzle, which is usually made of plastic or metal. The nozzle is internally designed with precise channels, and these channels determine the water flow rate and range. When the water source is turned on, the water pressure will push the water through these channels to form a high-pressure water flow for irrigation.

[0003] The irrigation range of the existing irrigation sprinklers is fixed. When dealing with large-scale greening irrigation, the fixed design is difficult to meet the irrigation requirements, and manual assistance is needed for the irrigation of the unirrigated areas, resulting in relatively high labor costs and deficiencies. Content of the Utility Model

[0004] (I) Purpose of the Utility Model

[0005] To solve the technical problems existing in the background technique, the utility model provides an automatic sprinkler for irrigation with an adjustable irrigation range, which has the characteristic of adjustable irrigation range.

[0006] (II) Technical Solution

[0007] To solve the above technical problems, the utility model provides an automatic sprinkler for irrigation with an adjustable irrigation range, including a base. The driving mechanism includes driving turntables symmetrically arranged on the base. An active pulley and a transmission pulley are respectively installed on the driving turntables, and the active pulley and the transmission pulley are connected by belt drive;

[0008] The slewing mechanism includes a slewing circular track arranged outside the belt. A slewing slide is arranged on the slewing circular track. A pulley frame is installed on the inner wall of the slewing slide. A pulley attached to the slewing circular track is installed on the pulley frame. A support plate is installed on the upper part of the pulley frame, and the side wall is connected to the belt through a belt connection seat;

[0009] The water supply mechanism includes a water distributor installed on the support plate. A water tank is arranged on one side of the water distributor, and water supply between the water tank and the water distributor is carried out by a water pump;

[0010] The spraying mechanism includes a sprayer connected to the water distributor. A main pipe is installed in the middle of the sprayer. Inclined branch pipes are installed on the main pipe, and nozzles are arranged at intervals on the branch pipes.

[0011] Preferably, the cross-section of the slewing circular track is a "mountain" structure and includes symmetrical straight sections and semi-circular sections.

[0012] Preferably, the rotary slide moves along the slot of the rotary circular rail. During the displacement process, the pulley rotates while adhering to the inner wall of the rotary circular rail.

[0013] Preferably, four pulleys are provided, and the pulleys rotate along the shaft rod in the pulley frame.

[0014] Preferably, the water distributor and the water pump are connected by a bendable hose.

[0015] Preferably, at least three branch pipes are provided and are installed on the main pipe in an equiangular array.

[0016] The above technical solution of the present invention has the following beneficial technical effects: A base is laid in the center of the irrigation area. Since the rotary slide is slidably installed on the rotary circular rail, with the center of the irrigation area as the reference point, the position of the rotary slide is adjusted by sliding, and then the position of the sprinkler is adjusted. The entire irrigation range is covered by means of rotary motion, which solves the problem that the fixed design of the nozzle is difficult to cope with the overall irrigation area and reduces the labor cost of irrigation.

Detailed Description of the Invention

[0022] To make the objectives, technical solutions, and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the present invention. In addition, in the following description, the descriptions of well-known structures and technologies are omitted to avoid unnecessarily confusing the concepts of the present invention.

[0023] As Figures 1-3As shown, the utility model provides an automatic sprinkler with adjustable irrigation range, comprising a base 1, a driving mechanism comprising a driving turntable 11 symmetrically arranged on the base 1, a driving pulley 12 and a transmission pulley 13 are respectively mounted on the driving turntable 11, and the driving pulley 12 and the transmission pulley 13 are connected by a belt 14;

[0024] The rotary mechanism includes a rotary circular rail 21 arranged outside the belt 14, a rotary slide 22 is arranged on the rotary circular rail 21, a pulley frame 23 is installed on the inner wall of the rotary slide 22, a pulley 24 attached to the rotary circular rail 21 is installed on the pulley frame 23, a support plate 25 is installed on the upper part of the pulley frame 23, and the side wall is connected to the belt 14 through a belt connecting seat 26;

[0025] The water supply mechanism includes a water distributor 31 mounted on the support plate 25, a water tank 33 is provided on one side of the water distributor 31, and water is supplied between the water tank 33 and the water distributor 31 through a water pump 32;

[0026] The spraying mechanism comprises a sprayer 41 connected to the water distributor 31 , a main pipe 42 is installed in the middle of the sprayer 41 , an inclined branch pipe 43 is installed on the main pipe 42 , and nozzles 44 are arranged at intervals on the branch pipe 43 .

[0027] It should be noted that the cross-section of the rotary circular rail 21 is a "mountain-shaped" structure, which has a protrusion in the middle and two slide grooves. Because it includes symmetrical straight sections and semicircular sections, the rotary slide 22 makes a linear displacement along the straight section grooves of the rotary circular rail 21 and makes an arc displacement along the semicircular section grooves. During the displacement process, the pulley 24 rotates against the inner wall of the rotary circular rail 21.

[0028] It should be added that: four pulleys 24 are provided in total, and the pulleys 24 rotate along the shaft in the pulley frame 23 and cooperate with the transmission of the belt 14 to switch the linear displacement into the circular displacement.

[0029] In this embodiment, the base 1 is laid in the center of the irrigation area. Since the rotary slide 22 is slidably installed on the rotary circular rail 21, the position of the rotary slide 22 can be adjusted by sliding. Taking the center of the irrigation area as the base point, the position of the sprayer 41 on the spraying mechanism is adjusted. The entire irrigation range is covered by the rotary motion, which solves the problem that the fixed design of the sprinkler head is difficult to cope with the entire irrigation area and reduces the labor cost of irrigation.

[0030] The water distributor 31 and the water pump 32 are connected via a bendable hose. When the water sprayer 31 moves with the support plate 25 on the rotary slide 22 , the hose can be stretched to prevent the hose from hindering the movement of the rotary slide 22 .

[0031] As a spraying example: The water in the water tank 33 is transported to the water distributor 31 through the water pump 32. After the sprinkler 41 receives the water supply from the water distributor 31, the water is distributed to the three branch pipes 43 through the main pipe 42. The three branch pipes 43 are installed on the main pipe 42 in an equally angled array, and the water is sprayed through the nozzles 44 to irrigate the soil and green plants.

[0032] It should be understood that the above specific embodiments of the present invention are only used for exemplary illustration or explanation of the principle of the present invention, and do not constitute a limitation to the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the protection scope of the present invention. In addition, the appended claims of the present invention are intended to cover all changes and modifications that fall within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
