Description

Technical Field

[0001] This utility model relates to the field of agricultural production technology, and more specifically, it relates to a multi-angle spraying device for agricultural production. Background Technology

[0002] In modern agricultural production, targeted spraying of pesticides is a crucial step in ensuring the healthy growth of crops and controlling pests and diseases. In large-scale farmland operations, due to the varying heights and leaf distributions of crops at different growth stages, precise application of pesticides to different parts is necessary. However, most agricultural spraying equipment on the market currently has significant shortcomings in terms of nozzle angle adjustment. These devices typically use fixed-angle nozzle designs, making it difficult to flexibly adjust the spray angle according to actual needs once installed. This results in pesticides not being evenly covered on different parts of the crop, especially with significant differences in spraying effects between the top and bottom leaves of taller crops. This not only leads to low pesticide use efficiency but may also result in incomplete pest and disease control, affecting crop yield and quality.

[0003] Traditional spraying equipment typically uses bolts or simple hinges for its angle adjustment mechanism, which is cumbersome and lacks precision, making it impossible to achieve rapid response and stepless adjustment during spraying. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the problems existing in the prior art, this utility model provides a multi-angle spraying device for agricultural production to solve the technical problems mentioned in the background art.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this utility model provides the following technical solution: a multi-angle spraying device for agricultural production, comprising a movable base, on which a spraying mechanism is mounted. The spraying mechanism includes a water tank, a water pump, a connecting pipe, a mounting frame, a diverter pipe, and nozzles. The water tank is mounted on the top surface of the movable base, the water pump is connected to the outside of the water tank, the connecting pipe is connected to the output end of the water pump, the mounting frame is mounted on the movable base, the diverter pipe is mounted on the outer wall of the mounting frame and connected to the connecting pipe, and multiple sets of nozzles are distributed on the outer wall of the diverter pipe. An adjustment mechanism is provided at the bottom of the mounting frame. The adjustment mechanism includes a connecting plate, a fixing rod, a mounting ring, a sliding groove, a positioning block, a tension spring, a positioning slot, and an abutment sleeve. The connecting plate is fixed to the bottom of the mounting frame, the fixing rod is fixed to the movable base, the mounting ring is fixed to the outer wall of the fixing rod and is rotatably connected to the connecting sleeve, multiple sets of sliding grooves are provided on the bottom surface of the mounting ring, the positioning block slides in multiple sets of sliding grooves, multiple sets of tension springs are provided and their two ends are respectively connected to multiple sets of positioning blocks and sliding grooves, multiple sets of positioning slots are provided on the inner wall of the connecting sleeve, and the abutment sleeve slides on the outer wall of the fixing rod.

[0008] The present invention is further configured such that the movable base is provided with an arc-shaped groove, and multiple sets of the arc-shaped groove are provided; the bottom surface of the mounting frame is fixedly provided with a limiting rod, and multiple sets of the limiting rod are provided and slide in multiple sets of arc-shaped grooves respectively. The combination design of multiple sets of arc-shaped grooves and limiting rods realizes the limitation of the rotation angle of the mounting frame, ensuring that the spray angle adjustment is within a reasonable range and preventing excessive rotation from causing pipe distortion.

[0009] The present invention is further configured such that all of the multiple sets of positioning blocks and positioning grooves are arc-shaped. The arc-shaped design increases the contact area, improves the stability of the fit between the positioning blocks and positioning grooves, and makes the locking after angle adjustment more secure and reliable.

[0010] The present invention is further configured such that each of the multiple sets of positioning blocks has a stop rod fixedly provided on its outer wall, and each of the multiple sets of stop rods is slidably connected to the mounting ring. The sliding connection structure between the stop rod and the mounting ring facilitates the precise control of the positioning block and improves the sensitivity of angle adjustment and the accuracy of positioning.

[0011] The present invention is further configured such that the outer wall of the fixing rod is provided with guide strips, and multiple sets of guide strips are provided and slidably connected to the abutment sleeve. The multiple sets of guide strips provide a stable sliding track for the abutment sleeve, ensuring that the abutment sleeve will not rotate or deviate during the movement, thereby enhancing the smoothness and accuracy of the adjustment process.

[0012] The present invention is further configured such that a limiting mechanism is provided on the outer wall of the fixed rod. The limiting mechanism includes a support rod, a limiting block, a rotating sleeve, a limiting groove, an unlocking hole, and an unlocking mechanism. Multiple sets of support rods are distributed on the top surface of the abutting sleeve. The limiting block is fixed to the top of the multiple sets of support rods. The rotating sleeve rotates on the outer wall of the fixed rod. Multiple sets of limiting grooves are distributed on the bottom surface of the rotating sleeve. The unlocking hole is located at one end of the multiple sets of limiting grooves. This limiting mechanism realizes the angle locking function after adjustment, preventing angle deviation caused by vibration during spraying operations. At the same time, the unlocking hole design makes locking and unlocking operations simple and quick.

[0013] The present invention is further configured such that the unlocking mechanism includes a contraction spring, a connecting plate, an arc-shaped slider, and an annular groove. The contraction spring is disposed on the outer wall of multiple sets of support rods and is fixedly connected to the abutment sleeve. The connecting plate is fixed to the top of multiple sets of contraction springs. The arc-shaped slider is fixed to the top surface of multiple sets of connecting plates. The annular groove is disposed on the bottom surface of the rotating sleeve and is slidably connected to multiple sets of arc-shaped sliders. The unlocking mechanism realizes the automatic reset function through the combination design of elastic elements and sliding structure, so that the user can perform the next angle adjustment without manually restoring the initial state, which greatly simplifies the operation process.

[0014] The present invention is further configured such that the connecting pipe is a flexible hose. Using a flexible hose as the connecting pipe enhances the flexibility and adaptability of the spray system, avoids the resistance and damage risk that may be caused by rigid pipes during angle adjustment, and extends the service life of the equipment.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, this utility model provides a multi-angle spraying device for agricultural production, which has the following beneficial effects:

[0017] 1. The spraying mechanism achieves uniform spraying in agricultural production by combining a water tank, water pump, connecting pipe, mounting bracket, diversion pipe and multiple sets of nozzles on a mobile base. The water pump delivers the liquid in the water tank to the diversion pipe through the flexible connecting pipe, and then the multiple sets of nozzles atomize and spray it. This design not only improves the coverage of the spray but also meets the spraying needs of crops at different growth stages.

[0018] 2. The adjustment mechanism adopts the coordinated work of connecting plate, fixing rod, mounting ring, sliding groove, positioning block, tension spring, positioning groove and abutment sleeve, combined with the design of arc groove and limit rod, so that the spray angle can be flexibly adjusted. Users can accurately adjust the spray angle according to crops of different heights and shapes, overcoming the shortcomings of traditional spraying equipment with fixed angles that are difficult to adjust, and improving the accuracy and efficiency of spraying.

[0019] 3. The limiting mechanism, through the support rod, limiting block, rotating sleeve, limiting groove, unlocking hole, and unlocking mechanism including contraction spring, connecting plate, arc slider and annular groove, realizes reliable fixing and convenient unlocking of the adjusted angle. This allows the operator to quickly lock the ideal spraying angle and easily unlock and readjust when needed, greatly improving the adaptability and operation continuity of the equipment in different agricultural environments and solving the problems of cumbersome adjustment and poor stability of traditional spraying equipment.

[0029] Please see Figures 1-5 A multi-angle spraying device for agricultural production includes a movable base 1, on which a spraying mechanism is mounted. The spraying mechanism includes a water tank 2, a water pump 3, a connecting pipe 4, a mounting frame 5, a diverter pipe 6, and nozzles 7. The water tank 2 is mounted on the top surface of the movable base 1, the water pump 3 is connected to the outside of the water tank 2, the connecting pipe 4 is connected to the output end of the water pump 3, the mounting frame 5 is mounted on the movable base 1, the diverter pipe 6 is mounted on the outer wall of the mounting frame 5 and connected to the connecting pipe 4, multiple sets of nozzles 7 are distributed on the outer wall of the diverter pipe 6, and an adjustment mechanism is provided at the bottom of the mounting frame 5, the adjustment mechanism including a connecting plate 8. The system includes a fixed rod 9, a mounting ring 10, a sliding groove 11, a positioning block 12, a tension spring 13, a positioning groove 14, and an abutment sleeve 15. The connecting plate 8 is fixed to the bottom of the mounting frame 5. The fixed rod 9 is fixed to the movable base 1. The mounting ring 10 is fixed to the outer wall of the fixed rod 9 and is rotatably connected to the connecting sleeve. Multiple sets of sliding grooves 11 are provided on the bottom surface of the mounting ring 10. The positioning block 12 slides in multiple sets of sliding grooves 11. Multiple sets of tension springs 13 are provided, and both ends are respectively connected to multiple sets of positioning blocks 12 and sliding grooves 11. Multiple sets of positioning grooves 14 are provided on the inner wall of the connecting sleeve. The abutment sleeve 15 slides on the outer wall of the fixed rod 9.

[0030] The movable base 1 has an arc-shaped groove 16, and there are multiple sets of arc-shaped grooves 16. The bottom surface of the mounting frame 5 is fixed with a limiting rod 17, and there are multiple sets of limiting rods 17, which slide in the multiple sets of arc-shaped grooves 16 respectively. The multiple sets of arc-shaped grooves 16 and the limiting rods 17 form a sliding constraint mechanism to limit the rotation range of the mounting frame 5. When the mounting frame 5 rotates, the limiting rods 17 slide in the arc-shaped grooves 16 to limit the angle and prevent excessive rotation.

[0031] Multiple sets of positioning blocks 12 and positioning grooves 14 are all set in an arc shape. The arc-shaped positioning blocks 12 and positioning grooves 14 provide a larger contact area and better fit. When the positioning block 12 is inserted into the positioning groove 14, the arc shape can ensure that the angle lock is more stable and reduce accidental loosening caused by vibration.

[0032] Multiple positioning blocks 12 are fixedly provided with abutment rods 18 on their outer walls. Multiple abutment rods 18 are slidably connected to the mounting ring 10. As an extension structure of the positioning block 12, the abutment rod 18 can push the abutment rod 18 when the abutment sleeve 15 slides upward, thereby driving the positioning block 12 to move into the positioning groove 14 to achieve precise positioning. At the same time, the slidable connection with the mounting ring 10 ensures that the movement trajectory is controllable.

[0033] The outer wall of the fixed rod 9 is provided with guide strips 19. Multiple sets of guide strips 19 are provided and are slidably connected to the abutment sleeve 15. The guide strips 19 provide a vertical guide track for the abutment sleeve 15, ensuring that the abutment sleeve 15 moves along the axis of the fixed rod 9 without deflection during the up and down movement, and ensuring accurate docking and stable contact with the abutment rod 18.

[0034] The outer wall of the fixed rod 9 is provided with a limiting mechanism, which includes a support rod 20, a limiting block 21, a rotating sleeve 22, a limiting groove 23, an unlocking hole 24, and an unlocking mechanism. The support rod 20 is provided with multiple sets distributed on the top surface of the abutment sleeve 15. The limiting block 21 is fixed to the top of the multiple sets of support rods 20. The rotating sleeve 22 rotates on the outer wall of the fixed rod 9. The limiting groove 23 is provided with multiple sets distributed on the bottom surface of the rotating sleeve 22. The unlocking hole 24 is provided at one end of the multiple sets of limiting grooves 23. The rotating sleeve 22 rotates to make the limiting block 21 enter the limiting groove 23 from the unlocking hole 24, thereby locking the position of the abutment sleeve 15 and preventing the abutment sleeve 15 from sliding down during use, thus maintaining the stability of the spray angle.

[0035] The unlocking mechanism includes a contraction spring 25, a connecting plate 26, an arc-shaped slider 27, and an annular groove 28. The contraction spring 25 is disposed on the outer wall of the multiple sets of support rods 20 and is fixedly connected to the abutment sleeve 15. The connecting plate 26 is fixed to the top of the multiple sets of contraction springs 25. The arc-shaped slider 27 is fixed to the top surface of the multiple sets of connecting plates 26. The annular groove 28 is disposed on the bottom surface of the rotating sleeve 22 and is slidably connected to the multiple sets of arc-shaped sliders 27. When the rotating sleeve 22 is rotated to unlock, the contraction spring 25 provides a rebound force to make the abutment sleeve 15 automatically descend. The arc-shaped slider 27 slides in the annular groove 28 to ensure that the rotating sleeve 22 can rotate smoothly, realizing the one-button unlocking and automatic reset functions.

[0036] The connecting pipe 4 is set as a flexible hose. The flexible connecting pipe 4 increases the flexibility of the spray system. When the mounting bracket 5 is adjusted, the hose can deform accordingly to adapt, avoiding stress damage caused by bending of rigid pipes, extending the service life of the equipment and ensuring smooth liquid transmission.

[0037] In this embodiment, during use, water is pumped from the water tank 2 by the water pump 3 and transported to the diversion pipe 6 through the connecting pipe 4. Then, it is atomized and sprayed through multiple sets of nozzles 7. When the spray angle needs to be adjusted, the rotating connecting sleeve rotates along the mounting ring 10. After rotating to the appropriate angle, the abutment sleeve 15 is pushed to slide along multiple sets of guide strips 19 so that it abuts against the top of multiple sets of abutment rods 18. This causes the multiple sets of abutment rods 18 to push the positioning block 12 to abut against the positioning groove 14 and stretch the tension spring 13. At this time, the limiting block 21 is in the unlocking hole 24. The rotating sleeve 22 is rotated counterclockwise so that the multiple sets of limiting blocks 21 slide into the limiting groove 23 to limit the abutment sleeve 15. At the same time, the abutment sleeve 15 stretches the contraction spring 25. When the rotating sleeve 22 rotates, the multiple sets of arc-shaped sliders 27 slide along the annular groove 28, thereby completing the positioning and fixing of the mounting bracket 5 after the angle adjustment.

[0038] More specifically, when readjustment is required, rotating the rotating sleeve 22 clockwise causes multiple sets of limiting blocks 21 to disengage from the limiting groove 23 and move into the unlocking hole 24, thereby releasing the contact between the limiting blocks 21 and the outer wall of the rotating sleeve 22. Then, the contraction spring 25 pulls the abutment sleeve 15 to slide and release the contact between the multiple sets of abutment rods 18. The multiple tension springs 13 pull the positioning block 12 out of the positioning groove 14, releasing the positioning and fixing of the connecting plate 8.

[0039] In summary, during use or operation of the overall equipment: During use, water is pumped from the water tank 2 by the water pump 3 and transported to the diversion pipe 6 through the connecting pipe 4. Then, it is atomized and sprayed through multiple sets of nozzles 7. When the spray angle needs adjustment, the rotating connecting sleeve rotates along the mounting ring 10. After rotating to the appropriate angle, it pushes the abutment sleeve 15 to slide along multiple sets of guide strips 19, causing it to abut against the top of multiple sets of abutment rods 18. This causes the multiple sets of abutment rods 18 to push the positioning block 12 against the positioning groove 14 and stretch the tension spring 13. At this time, the limiting block 21 is in the unlocking hole 24. Rotating the rotating sleeve 22 counterclockwise causes the multiple sets of limiting blocks 21 to slide into the limiting groove 23, limiting the abutment sleeve 15. Simultaneously, the abutment sleeve 15 stretches the contraction spring 25. As the rotating sleeve 22 rotates, multiple sets of arc-shaped sliders 27 slide along the annular groove 28, thus completing the positioning and fixing of the mounting frame 5 after angle adjustment.

[0040] However, when adjustment is needed again, rotating the rotating sleeve 22 clockwise causes multiple sets of limiting blocks 21 to disengage from the limiting groove 23 and move into the unlocking hole 24, thereby releasing the contact between the limiting blocks 21 and the outer wall of the rotating sleeve 22. Then, the contraction spring 25 pulls the abutment sleeve 15 to slide and release the contact between the multiple sets of abutment rods 18. The multiple sets of tension springs 13 pull the positioning block 12 out of the positioning groove 14, releasing the positioning and fixing of the connecting plate 8.

[0041] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
