Description

Technical Field

[0001] This utility model relates to the field of agricultural irrigation technology, specifically to an agricultural irrigation sprinkler frame. Background Technology

[0002] In modern agricultural production, sprinkler irrigation, as an efficient water-saving irrigation method, is widely used for irrigation of field crops, orchards, and tall cash crops. As the core component of the sprinkler irrigation system, the performance of the sprinkler frame directly affects the uniformity of irrigation, the efficiency of water resource utilization, and the impact on crop growth.

[0003] Currently, the sprinkler frames commonly used in agricultural production are mostly single-tube or truss structures with several nozzles installed at equal intervals. This traditional structure has two major technical defects that urgently need to be addressed: First, to meet the needs of wide-area operations, existing designs often expand the spraying range by extending the truss span. As the truss length increases, its overall bending stiffness decreases significantly. Moreover, ultra-long trusses need to be stored or moved when not in operation, but their size far exceeds the cargo space of conventional transport vehicles, often requiring partial disassembly, which is cumbersome, time-consuming, and labor-intensive. Second, crops have different requirements for spraying height at different growth stages (such as seedling stage, growth stage, and maturity stage). Existing sprinkler frames cannot quickly adapt to crop height. Therefore, a new type of sprinkler frame structure is urgently needed that can improve ease of use and environmental adaptability while ensuring sufficient spraying coverage. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the existing technology, the purpose of this utility model is to provide an agricultural irrigation sprinkler frame, which effectively solves the problems of inconvenient transportation and inability to quickly adjust according to crop height caused by the large span of traditional sprinkler frames.

[0005] The technical solution is as follows: This utility model includes a fixed frame, a telescopic rod hinged to the upper side of the fixed frame, a bracket fixedly connected to the right end of the telescopic rod, a balance rod hinged to the lower end of the bracket, the balance rod being slidably connected to the fixed frame, connecting pipes fixedly connected to the front and rear ends of the bracket respectively, an adapter pipe sleeved inside the connecting pipe, a lifting cylinder that can drive the adapter pipe to rotate on the upper side of the connecting pipe, a push frame slidably connected to the front and rear sides of the bracket respectively, a lifting groove opened on the upper side of the push frame, a lifting pin fixedly connected to the left side of the lifting cylinder in the corresponding lifting groove, a swingable drive frame on the fixed frame, the right side of the drive frame hinged to the right side of the telescopic rod, grooved wheels fixedly connected to the front and rear sides of the drive frame respectively, and a movable pin that can cooperate with the grooved wheel on the corresponding side fixedly connected to one end of the push frame.

[0006] The inner wall of the lifting cylinder is provided with a toggle groove, and a toggle pin located in the corresponding toggle groove is fixedly connected to the upper side of the transfer pipe.

[0007] The bracket has a main spray pipe on the front and rear sides that can communicate with the corresponding connecting pipe. The outer wall of the connecting pipe has a rotating groove. The outer wall of the connecting pipe is fixedly connected to an expansion pipe located in the rotating groove. Both the main spray pipe and the expansion pipe are equipped with multiple spray heads evenly distributed along their front and rear directions.

[0008] A lead screw is rotatably connected inside the fixed frame, and a movable frame is threadedly connected to the outer wall of the lead screw. The front and rear sides of the movable frame are respectively hinged to the drive frame. A drive motor is installed inside the fixed frame, and the output end of the drive motor is fixedly connected to the left end of the lead screw.

[0009] The connecting pipe has a clearance groove on its left side, and the lifting pin is located in the clearance groove on its corresponding side.

[0010] A water inlet pipe is fixedly connected to the middle of the bracket, and the front and rear sides of the water inlet pipe are rotatably connected to the corresponding spray pipes on their respective sides.

[0012] Beneficial effects

[0013] This utility model adopts a linkage deployment and lifting mechanism. Through the cooperation of the drive frame, grooved wheel and movable pin, the extension tube is automatically deployed in the early stage of the support to increase the spray coverage area. After deployment, the extension tube is locked and the support height is raised smoothly. This effectively realizes the rapid storage of the spray frame and precise control of the working height, improving the automation level and work efficiency of the equipment.

[0014] This utility model utilizes the rotating connection design of the adapter pipe and the connecting pipe, combined with the actuating groove and actuating pin in the lifting cylinder, to transform the horizontal movement of the push frame into the rotational unfolding action of the extension pipe, realizing the storage and rapid unfolding of the spray pipe, solving the problem of inconvenient transportation and storage of ultra-wide trusses, with a compact structure and strong practicality.

[0021] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0022] Depend on Figures 1 to 5 The system includes a fixed frame 1, a telescopic rod 2 hinged to the upper side of the fixed frame 1, a bracket 3 fixedly connected to the right end of the telescopic rod 2, a balance rod 4 hinged to the lower end of the bracket 3, the balance rod 4 being slidably connected to the fixed frame 1, connecting pipes 5 fixedly connected to the front and rear ends of the bracket 3 respectively, an adapter pipe 6 sleeved inside the connecting pipe 5, a lifting cylinder 7 on the upper side of the connecting pipe 5 that can drive the adapter pipe 6 to rotate, a push frame 8 slidably connected to the front and rear sides of the bracket 3 respectively, a lifting groove 9 opened on the upper side of the push frame 8, a lifting pin 10 fixedly connected to the left side of the lifting cylinder 7 located in the corresponding lifting groove 9, a swingable drive frame 11 on the fixed frame 1, the right side of the drive frame 11 being hinged to the right side of the telescopic rod 2, grooved wheels 12 fixedly connected to the front and rear sides of the drive frame 11 respectively, and a movable pin 13 fixedly connected to one end of the push frame 8 that can cooperate with the grooved wheel 12 on its corresponding side.

[0023] like Figures 1 to 5As shown, the fixed frame 1 serves as the installation foundation and support body for the entire spray frame, providing structural stability. A telescopic rod 2 and a balance rod 4 are installed to connect the fixed frame 1 and the support 3. These rods maintain the balance and stability of the support 3 during lifting and lowering, preventing tilting or swaying. The support 3 supports the spray pipes and spray heads 18, forming a spraying working surface. A connecting pipe 5 and an adapter pipe 6 are installed, allowing the extension pipe 17 to be expanded and retracted by rotating the adapter pipe 6 within the connecting pipe 5. This also ensures pipe connection between the main spray pipe 16 and the extension pipe 17, guaranteeing that water can flow normally into the extension pipe 17 and expand the spraying range. A lifting cylinder 7, lifting pin 10, a pushing frame 8, and a lifting groove 9 are installed, allowing the pushing frame 8 to move back and forth through the lifting groove 9 and lifting pin 10. The lifting cylinder 7 is raised and lowered, which in turn rotates the transfer pipe 6. The drive frame 11 can drive the support 3 to rise and fall, so as to adjust the spraying height according to the crop height. The grooved wheel 12 and movable pin 13 are set so that when the drive frame 11 swings, the push frame 8 can be moved horizontally through the cooperation of the grooved wheel 12 and movable pin 13. This allows the extension pipe 17 to be opened first when adjusting the height, achieving the purpose of linkage control. The movable groove on the grooved wheel 12 is divided into two parts. The first part is the drive groove. When the movable groove is in the drive groove, it can drive the push frame 8 to move back and forth in the horizontal direction. The second part is the ring groove. When the movable pin 13 enters the ring groove, the rotation of the grooved wheel 12 will no longer drive the push frame 8 to move, ensuring that the extension pipe 17 can be opened and used at the beginning of the support 3's rise.

[0024] The inner wall of the lifting cylinder 7 is provided with a toggle groove 14, and the upper side of the transfer pipe 6 is fixedly connected with a toggle pin 15 located in the toggle groove 14 on its corresponding side.

[0025] like Figure 4 As shown, the actuating groove 14 and actuating pin 15 are provided so that when the lifting cylinder 7 rises or falls under the drive of the push frame 8, the actuating groove 14 on its inner wall will act on the actuating pin 15 on the adapter pipe 6. Since the adapter pipe 6 can only rotate within the connecting pipe 5, the force exerted by the actuating groove 14 on the actuating pin 15 will force the adapter pipe 6 to rotate accordingly, thereby realizing the expansion or retraction of the expansion tube 17.

[0026] The bracket 3 has a spray main pipe 16 on the front and rear sides, which can communicate with the corresponding connecting pipe 5. The outer wall of the connecting pipe 5 has a rotating groove. The outer wall of the connecting pipe 6 is fixedly connected to an expansion pipe 17 located in the rotating groove. Both the spray main pipe 16 and the expansion pipe 17 are provided with multiple spray heads 18 evenly distributed in their front and rear directions.

[0027] like Figures 2 to 5As shown, the main sprinkler pipe 16 serves as the main water supply pipeline, transporting and distributing irrigation water to the sprinkler heads 18 for sprinkler operation. The connecting pipe 5 and the adapter pipe 6 are key components connecting the main sprinkler pipe 16 and the expansion pipe 17. The rotating groove on the outer wall of the connecting pipe 5 provides rotation space and axial limit for the adapter pipe 6, allowing the expansion pipe 17 to rotate, thus expanding the working width of the sprinkler frame and solving the problem of inconvenient transportation of ultra-long trusses. The sprinkler heads 18 are set up so that the water in the pipe can be sprayed out in a preset form and angle to complete the irrigation operation.

[0028] The fixed frame 1 is rotatably connected to a lead screw 19, and a movable frame 20 is threadedly connected to the outer wall of the lead screw 19. The front and rear sides of the movable frame 20 are respectively hinged to the drive frame 11. The fixed frame 1 is equipped with a drive motor 21, and the output end of the drive motor 21 is fixedly connected to the left end of the lead screw 19.

[0029] like Figure 2 As shown, the drive motor 21, lead screw 19 and moving frame 20 work together. The rotation of lead screw 19 drives the moving frame 20 to move in the left and right directions. Then, the moving frame 20 drives the support 3 to rise and fall through the drive frame 11. Lead screw 19 has good self-locking ability to ensure that the support 3 has good support after rising.

[0030] The left side of the connecting pipe 5 is provided with a clearance groove, and the lifting pin 10 is located in the clearance groove on its corresponding side.

[0031] like Figure 5 As shown, the clearance groove provides space for the lifting pin 10 to move and limits its range of movement.

[0032] The bracket 3 is fixedly connected to the middle of the water inlet pipe 22, and the front and rear sides of the water inlet pipe 22 are respectively rotatably connected to the corresponding spray pipe 16.

[0033] like Figures 1 to 2 As shown, the water inlet pipe 22 can be connected to an external water tank to distribute water flow to the spray pipes 16 on both sides.

[0034] The left end of the fixed frame 1 is fixedly connected to the connecting frame 23. The connecting frame 23 has connecting holes on the front and rear sides respectively. The fixed frame 1 is provided with a moving wheel 24.

[0035] like Figure 1 As shown, the connecting frame 23 and connecting hole are provided to connect agricultural machinery, which facilitates the movement of the sprayer. The moving wheels 24 are provided to support and facilitate movement.

[0036] In use, this utility model connects to an agricultural machine using the connecting frame 23 and connecting hole. Then, the water inlet pipe 22 is connected to the water tank to prepare for the spraying operation. Then, the drive motor 21 is started, which drives the lead screw to rotate, causing the moving frame 20 to move to the right. The moving frame 20 pushes the lower end of the drive frame 11, causing the support 3 to rise slowly. The grooved wheel 12 on the drive frame 11 rotates accordingly. Its drive groove part drives the push frame 8 to move to the outside of the fixed frame through the movable pin 13. The movement of the push frame 8 acts on the lifting pin 10 through the lifting groove 9 on it, thereby converting the horizontal movement into the upward movement of the lifting cylinder 7. The actuating groove 14 on the inner wall of the lifting cylinder 7 drives the actuating pin 15, forcing the transfer pipe 6 and its connected extension pipe 17 to rotate outward and unfold in the connecting pipe 5, thereby widening the working width of the entire spraying frame.

[0037] When the pusher 8 moves to the predetermined position, i.e. the expansion tube 17 is fully extended, the movable pin 13 just slides into the annular groove of the grooved wheel 12. The drive motor 21 continues to work, and the moving frame 20 continues to move to the right. At this time, since the movable pin 13 is spinning freely in the annular groove, the rotation of the grooved wheel 12 no longer drives the pusher 8 to move, the expansion tube 17 is locked, and the drive frame 11 continues to swing through the hinge point between its upper end and the telescopic rod 2, pushing the entire bracket 3 upward. During the rise of the bracket 3, the telescopic rod 2 and the balance rod 4, which are hinged to both the bracket 3 and the fixed frame 1, work together to ensure that the bracket 3 rises and falls smoothly and avoids lateral tilting and swaying.

[0038] When the support 3 is raised to the required height for the crop, the drive motor 21 stops, and the external water source enters the spray main pipes 16 on both sides through the water inlet pipe 22, and then flows into the extended expansion pipe 17 through the connecting pipe 5 and the transfer pipe 6. Finally, the spray head 18 on all the pipes performs a large-scale spraying operation at an appropriate height.

[0039] After the operation is completed, the drive motor 21 reverses, and the whole process is carried out in reverse until the bracket 3 descends to the lowest point and the extension tube 17 is completely retracted, at which point the drive motor 21 can be turned off.

[0040] In this utility model, the drive motor 21 and the telescopic rod 2 are both existing technologies and will not be described in detail here.

[0041] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
