Description

Technical Field

[0001] The present invention relates to the technical field of sprinklers, and particularly to a water-saving sprinkler for agricultural machinery operations. Background Art

[0002] In the prior art, water-saving irrigation technology has become a research hotspot at home and abroad. As the main body of the sprinkler, the sprinkler chassis is mainly used to carry the sprinkler pipe system and support the entire sprinkler bracket to complete the field irrigation operation task.

[0003] For example, a water-saving nursery sprinkler with the publication number CN106489679A has the perpendicular bisector of the vehicle frame arranged perpendicular to the horizontal plane. The front wheels are installed at the lower end of the vehicle frame, and the limiting columns are installed on the left and right sides of the upper end surface of the vehicle frame. The central axis of the limiting column is arranged perpendicular to the upper end surface of the vehicle frame. A counterweight is installed on the limiting column. The counterweight is of a cylindrical structure and a through hole is provided at the middle position of the counterweight. The movement of the vehicle frame is realized by adding the front wheels. This design solves the problem of limited spraying area of traditional sprinklers. The design of the spraying frame and the accessory frame realizes the installation of the spray heads. When the spraying area is relatively wide, the single spraying area is increased through the accessory frame. The addition of the rotating shaft facilitates the staff to adjust the position of the spraying frame according to needs. In addition, the counterweight solves the problem of uneven weight on one side of the vehicle frame caused by the rotation of the spraying frame.

[0004] The above technical solution has some problems in practical applications. When the above technical solution is used for sprinkler irrigation operations, it cannot adjust the sprinkler height and the amount of water sprayed according to the growth conditions of crops. Moreover, the water source of the sprinkler generally comes from a well, and the water contains more sediment, so the spray heads are easily blocked during sprinkler irrigation, resulting in uneven sprinkler irrigation.

Detailed implementation manners

[0035] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0036] Embodiment 1, as Figures 1 to 13 shown, a water-saving sprinkler for agricultural machinery operation provided by the present invention is essentially a sprinkler that can automatically adjust the water output according to the sprinkler density. A support rod 3 is provided at the top of the frame 1. Below the support rod 3, there are multiple foldable support arms 5. A support 6 is provided at the connection of the two support arms 5. Below the support 6, there is an annular cover 7. Multiple spray nozzles 71 are provided on the outer side of the annular cover 7. Inside the annular cover 7, there is a water guide sleeve 72. Inside the water guide sleeve 72, there is a water inlet pipe 8 that can slide up and down. When the support arm 5 folds, it can drive the water inlet pipe 8 to move up and down, so as to adjust the position between the water inlet pipe 8 and the connection groove 74 on the inner wall of the water guide sleeve 72, thereby achieving the effect of adjusting the water output. The folding of the support arm 5 can drive the annular cover 7 to move, so that its height and density are both adjusted, thereby synchronously adjusting the irrigation amount while adjusting the irrigation density to achieve the water-saving effect.

[0037] In the specific structural installation, the structural body can be constructed according to the inventive concept of this embodiment. In this embodiment, no special limitation is made.

[0038] In this embodiment, a water-saving sprinkler for agricultural machinery operation includes: A frame 1, with traveling wheels 24 provided at its four corners, and a water tank 2 is provided above the frame 1. The water tank 2 is filled with sprinkler water. Inside the traveling wheels 24, there is a motor for driving, which is used to drive the frame 1 to move in a specified direction. During use, the motor is electrically connected to a corresponding controller and power supply; a support rod 3, which is located at the top of the frame 1 and extends to the left and right sides of the frame 1; a support base 17, which is located at the top of the frame 1 and is fixedly connected to the middle of the support rod 3; multiple support columns 18, all of which are located above the frame 1. The multiple support columns 18 are connected to each other by bolts. The multiple support columns 18 are used to fix the position of the support base 17. The bottommost support column 18 is connected to the frame 1 by bolts. During use, the number and height of the support columns 18 to be installed can be selected according to requirements; a positioning frame 19, which is provided on the top of the frame 1 by bolts. Inside the positioning frame 19, there is a wire reel 20. A lifting rope 21 is provided on the outer side of the wire reel 20. The two ends of the lifting rope 21 are respectively connected to the corresponding ends of the support rod 3. The lifting rope 21 is used to assist in supporting the support rod 3 to keep the whole support rod 3 in a horizontal state; an adjustment assembly 10, which is placed in the middle of the support rod 3 and is used to adjust the spacing of the annular cover 7.

[0039] Specifically, it further includes a sliding sleeve 4 which is slidably sleeved outside the support rod 3. There are multiple sliding sleeves 4. There are multiple support arms 5 which are all located below the support rod 3. The upper end of each support arm 5 is rotatably connected to the corresponding sliding sleeve 4. There are supports 6. The lower ends of two adjacent support arms 5 are rotatably connected to the corresponding supports 6. During use, the sliding sleeve 4 slides left and right along the support rod 3 to change the angle between the corresponding support arms 5, thereby adjusting the distance between multiple supports 6 and the distance of the supports 6 relative to the support rod 3.

[0040] More specifically, it further includes an annular cover 7 which is located below the support 6 and is provided with a plurality of water spray nozzles 71 around the bottom end of the outer wall. And a water guide sleeve 72 is arranged inside the annular cover 7. The annular cover 7 is fixedly connected to the corresponding support 6. The water spray nozzle 71 is set as a conical structure to improve the sprinkler irrigation effect. And the water spray nozzle 71 is connected to the annular cover 7 by threads, so as to facilitate replacing water spray nozzles 71 of different specifications according to needs during use to meet different degrees of sprinkler irrigation requirements. An inlet pipe 8, the outlet end of which is placed inside the water guide sleeve 72 and can slide up and down, is used to adjust the water output of the water spray nozzle 71. The inlet pipe 8 is made of a rigid material. The outer wall of the inlet pipe 8 is slidably sealed with the inner wall of the water guide sleeve 72. A connecting pipe 73 which is located between the annular cover 7 and the water guide sleeve 72 and is fixedly connected to the annular cover 7 and the water guide sleeve 72. A connecting groove 74 which is arranged on the inner wall of the water guide sleeve 72 and is set as a strip-shaped structure. The connecting groove 74 penetrates through the connecting pipe 73 to communicate the annular cover 7 with the water guide sleeve 72. The water in the water guide sleeve 72 enters the annular cover 7 through the connecting groove 74 and the connecting pipe 73. The inlet pipe 8 slides up and down to control the opening range of the connecting groove 74.

[0041] It should be noted that during the sprinkler irrigation process, when the inlet pipe 8 is in a relatively upper position, the side wall of the inlet pipe 8 blocks the connecting groove 74, reducing the water flow rate of the connecting groove 74, and thus reducing the water spray amount of the water spray nozzle 71. When the inlet pipe 8 is in a relatively lower position, the side wall of the inlet pipe 8 reduces the blocked area of the connecting groove 74, increasing the water flow rate of the connecting groove 74, and at this time the water spray amount of the water spray nozzle 71 increases.

[0042] Specifically, it further includes a water pump 22 which is located at the top of the water tank 2. The output end of the water pump 22 is communicated with the inlet pipe 8 through a hose. The water pump 22 is electrically connected to a corresponding controller and a power source during use.

[0043] More specifically, it further includes a movable seat 11 fixedly connected to the bottom end of the water inlet pipe 8; a sliding seat 12 located below the support 6 and capable of sliding up and down along the support 6. The support 6 is placed above the annular cover 7. A tension spring 13 is provided between the sliding seat 12 and the support 6, and both ends of the tension spring 13 are fixedly connected to the sliding seat 12 and the support 6 respectively. A connecting screw rod 14 is provided between the sliding seat 12 and the movable seat 11, and the connecting screw rod 14 passes through the gap between the annular cover 7 and the water guide sleeve 72.

[0044] A connecting nut 16 is threadedly engaged on the outer side of the connecting screw rod 14. The connecting nut 16 is rotatably connected to the middle of the movable seat 11. The connecting nut 16 and the connecting screw rod 14 are used to adjust the distance between the sliding seat 12 and the movable seat 11. By adjusting the distance between the connecting nut 16 and the connecting screw rod 14, the initial position of the water inlet pipe 8 can be adjusted to control the initial irrigation amount of water.

[0045] A pressing seat 15 is rotatably connected to the top of the sliding seat 12 and is symmetrically arranged. Each pressing seat 15 is in contact with the outer side wall of the corresponding support arm 5. The support arm 5 rotates to push the pressing seat 15 to drive the sliding seat 12 to move up and down. When the support arms 5 on both the left and right sides of the support 6 rotate upward relative to the support 6 simultaneously during use, the tension spring 13 pulls the sliding seat 12 upward, and at this time the water inlet pipe 8 slides upward. On the contrary, when the support arms 5 rotate downward relative to the support 6 simultaneously, the support arms 5 push the sliding seat 12 downward through the pressing seat 15. At this time, the tension spring 13 extends under the influence of the tensile force, and the water inlet pipe 8 slides downward; by adjusting the relative angle between the two support arms 5, the distance between the water inlet pipe 8 and the connecting groove 74 can be adjusted to control the amount of water entering the annular cover 7.

[0046] It should be noted that when the annular cover 7 is placed at a lower position, the spray nozzle 71 is closer to the ground. At the same time, the water inlet pipe 8 will largely block the connecting groove 74, reducing the flow rate of the spray nozzle 71 and lowering the pressure at the outlet of the spray nozzle 71. At this time, it is suitable for smaller plants or seedlings, and can effectively reduce the impact of irrigation on the plants; on the contrary, when the annular cover 7 is placed at a higher position, the spray nozzle 71 is farther from the ground, and the degree of blockage of the connecting groove 74 by the water inlet pipe 8 is reduced, increasing both the flow rate and the outlet pressure of the spray nozzle 71. At this time, it is suitable for taller plants, and taller plants require a larger irrigation amount; therefore, in actual irrigation operations, the height of the annular cover 7 can be adjusted according to the size and water demand of the plants, and the water output of the spray nozzle 71 can be adjusted synchronously.

[0047] Specifically, the adjustment component 10 includes a tensioning wheel 101, which is rotatably connected to the upper end of the support rod 3 and is symmetrically arranged on the left and right; a synchronous pull rope 102, which is sleeved between the two tensioning wheels 101, and the cooperation between the synchronous pull rope 102 and the tensioning wheel 101 can also improve the effect of keeping the support rod 3 horizontal; the two sliding sleeves 4 away from the middle of the support rod 3 are fixedly connected to the synchronous pull rope 102, and the connection positions are respectively placed in the front and rear directions relative to the tensioning wheel 101, to ensure that when the synchronous pull rope 102 moves, the sliding sleeves 4 on the left and right sides can slide synchronously in opposite directions; a conveying motor 103, which is fixedly connected to the middle of the support rod 3, and the conveying motor 103 is used to drive the synchronous pull rope 102 to slide. The conveying motor 103 is electrically connected to the corresponding controller and power supply during use.

[0048] It should be noted that during use, the synchronous pull rope 102 is driven to move by the conveying motor 103, and at the same time, the synchronous pull rope 102 causes the sliding sleeves 4 on the left and right sides to move closer to or away from the middle at the same time, and through the cooperation of the support arm 5, multiple supports 6 and sliding sleeves 4 are adjusted at the same time, so as to achieve the purpose of controlling the spacing and height of multiple annular covers 7.

[0049] In summary, when the land is sprinkled, the sprinkler water is filled in the water tank 2 in advance, and the frame 1 is placed in an appropriate position, and then the water pump 22 is started to allow water to enter the water guide sleeve 72 through the water inlet pipe 8, and then the water is sprayed out from the water outlet after filling the annular cover 7; the conveying motor 103 and the synchronous pull rope 102 drive the sliding sleeves 4 on the left and right sides to move, and at the same time, the angle between the corresponding support arms 5 changes, thereby adjusting the spacing between the multiple supports 6 and the distance between the support 6 and the support rod 3; at the same time, when the support arms 5 rotate downward relative to the support 6 at the same time, the support arms 5 push the slide seat 12 downward through the pressure seat 15, and at this time the tension spring 13 extends under the influence of the tension, the water inlet pipe 8 slides downward, and the side wall of the water inlet pipe 8 reduces the blockage area of ​​the connecting groove 74, so that the water flow rate of the connecting groove 74 is increased, and the water spraying amount of the water nozzle 71 increases, otherwise it decreases.

[0050] Then, the frame 1 is driven to move by the driving motor inside the traveling wheel 24, and the land is sprinkled step by step.

[0051] Embodiment 2: In actual use, since the water source generally comes from a machine well and contains more sediment, it is very easy to cause the water nozzle 71 to be blocked. Therefore, the water nozzle 71 needs to be frequently replaced and unblocked during use, which seriously affects the sprinkler irrigation effect. For this reason, the relevant components of this device are further improved.

[0052] Specifically, Figures 8 to 9 , and also includes a filter plate 9, which is fixedly connected to the middle part of the annular cover 7. The bottom of the filter plate 9 is placed in the water inlet pipe 8, and the water inlet pipe 8 can slide back and forth relative to the filter plate 9; during use, the water inlet pipe 8 can slide out of the water guide sleeve 72 and separate from the filter plate 9.

[0053] More specifically, it further includes a rubber ring 23, which is fixedly connected to the upper end of the filter plate 9. The outer side of the rubber ring 23 can fit with the inside of the water guide sleeve 72. When the water inlet pipe 8 is inserted into the water guide sleeve 72, the top of the water inlet pipe 8 pushes the rubber ring 23 upward, so that the end of the water inlet pipe 8 can enter the water guide sleeve 72.

[0054] It should be noted that during use, the filter plate 9 filters the water flowing into the water guide sleeve 72, so that impurities are blocked in the water inlet pipe 8, preventing the impurities from entering the spray nozzle 71 and causing blockage. When the filter plate 9 is blocked, the adjustment assembly 10 is used to flip the support arm 5 and squeeze the movable seat 11 to slide downward, so that the water inlet pipe 8 slides out of the water guide sleeve 72. At the same time, the rubber ring 23 flips to seal the gap between the filter plate 9 and the water guide sleeve 72. At this time, the impurities in the water inlet pipe 8 directly discharge through the outlet of the water inlet pipe 8 and impact the bottom of the filter plate 9, washing the impurities down. The rubber ring 23 can prevent the water containing impurities from entering the upper end of the filter plate 9. Subsequently, the adjustment assembly 10 resets the water inlet pipe 8 through the support arm 5 to achieve the purpose of dredging the water inlet pipe 8.

[0055] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
