Description

Technical Field

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

[0002] In the field of modern agricultural production, efficient and uniform fertigation is a key technology for improving crop yield and quality. With the development of precision agriculture, farmers and planting enterprises are increasingly using water-soluble fertilizers. These fertilizers need to be fully mixed with water and then sprayed evenly onto the crop roots or leaves. However, traditional fertilization equipment has obvious shortcomings in the fertilizer and water mixing process. Common problems include uneven mixing leading to inconsistent fertilizer concentration distribution, insufficient dissolution causing nozzle blockage, and cumbersome and time-consuming manual operation during the mixing process.

[0003] During fertilization, the spraying volume needs to be flexibly adjusted according to different plant species, growth stages and soil conditions to achieve the best fertilizer utilization rate and reduce environmental pollution. Existing spraying equipment generally lacks an effective flow regulation mechanism. It either cannot achieve precise control of minute flow changes or the adjustment device is complicated and inconvenient for on-site operation. In particular, it is difficult to maintain the uniformity of spraying when spraying large areas. In addition, due to insufficient adjustment precision, it is easy to cause excessive or insufficient fertilizer during fertilization, which not only wastes resources and increases costs, but may also cause environmental problems such as plant nutrient imbalance, soil salinity accumulation and even groundwater pollution. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] In view of the problems existing in the prior art, the present invention provides a spraying device 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 spraying device includes a trolley, on which a spraying mechanism is mounted. The spraying mechanism includes a mounting shell, a mixing cylinder, a water pump, a delivery pipe, an output pipe, an adjusting mechanism, a diverting pipe, and a nozzle. The mounting shell is fixed to the trolley, the mixing cylinder is fixed to the bottom of the mounting shell, the water pump is connected to the outer wall of the mixing cylinder, the delivery pipe is fixed to the output end of the water pump, and the output pipe is located at the top of the delivery pipe. The adjusting mechanism includes a connecting sleeve, an adjusting sleeve, a transmission sleeve, a mating block, a mating rod, a spiral groove, a connecting plate, a control sleeve, and an adjusting... The system includes a junction hole and a sealing sleeve. The connecting sleeve is fixed to the top of the delivery pipe. The adjusting sleeve rotatably connects the connecting sleeve and the output pipe. The transmission sleeve is fixed inside the adjusting sleeve. Multiple sets of mating blocks are distributed inside the transmission sleeve. The mating rod moves on the inner wall of the transmission sleeve. The spiral groove is set on the outer wall of the mating rod and is slidably connected to multiple sets of mating blocks. The connecting plate is fixed to the bottom of the mating rod. The control sleeve is set on the top surface of the connecting plate. Multiple sets of adjusting holes are distributed on the outer wall of the control sleeve. The sealing sleeve is set on the inner wall of the connecting sleeve and is slidably connected to the outer wall of the control sleeve. The diversion pipe is fixed to the top of the output pipe. The nozzle is connected to the outer wall of the diversion pipe.

[0008] This invention is further configured such that a feeding hopper is fixedly provided at the top of the mounting shell. The funnel-shaped structure increases the feeding area, reduces splashing, and the inclined inner wall guides the material to flow naturally into the mixing area, making it suitable for adding various fertilizers.

[0009] The present invention is further configured such that a fixing frame is fixedly provided on the outer wall of the mounting shell, and the bottom end of the fixing frame is fixed to the outer wall of the output pipe. The fixing frame forms a triangular stable structure to enhance the rigidity of the system, reduce vibration and sway, prevent loosening of connections and deformation of pipes, distribute water pressure and weight, and extend the service life of the equipment.

[0010] The present invention is further configured such that multiple sets of nozzles are distributed on the outer wall of the diversion pipe. The multiple sets of nozzles form a fan-shaped spraying area, expanding the coverage area of ​​the operation. The pressure inside the diversion pipe is balanced to ensure consistent water output and avoid local over- or under-fertilization.

[0011] The present invention is further configured such that the outer side of the control sleeve is polygonal and slidably connected to the cover. The polygonal design prevents rotation during sliding, ensures accurate positioning of the adjustment hole, and the angular structure increases the contact area, improving stability and sealing performance.

[0012] This invention is further configured such that all sets of mating blocks are arc-shaped and slide within the spiral groove. The arc-shaped design creates surface contact, increasing load-bearing capacity, reducing unit force and wear, making sliding smoother, reducing resistance and jamming, and improving adjustment sensitivity.

[0013] The present invention is further configured such that the spiral groove and the outer sides of the multiple sets of mating blocks are all provided with rounded corners. The rounded corner design eliminates stress concentration, improves fatigue resistance, reduces friction for smoother adjustment, reduces wear risk, and ensures long-term precise adjustment.

[0014] This invention is further configured such that a mixing mechanism is provided inside the mounting shell. The mixing mechanism includes a rotating rod, a stirring frame, a screw rod, and a motor. The rotating rod rotates inside the mounting shell, the stirring frame is fixed to the bottom end of the rotating rod, the screw rod is fixed to the bottom end of the stirring frame, and the motor is fixed to the outside of the mounting shell with its output end fixedly connected to the rotating rod. The three-stage mixing design creates a three-dimensional mixing effect from top to bottom, improving uniformity and dissolution speed. The external motor facilitates heat dissipation and maintenance, and avoids water and fertilizer corrosion.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a spraying device with the following beneficial effects:

[0017] 1. The spraying mechanism, through its integrated design of a housing, mixing cylinder, water pump, delivery pipe, output pipe, distribution pipe, and nozzles, solves the problem of low efficiency in traditional water and fertilizer application. Using a trolley as a mobile platform, the mechanism organically combines water and fertilizer mixing with spraying functions, achieving a complete process from mixing to final spraying. The feed hopper facilitates raw material addition, while the support structure of the fixed frame ensures the stability of the output pipe, effectively preventing shaking and leakage during transport. Multiple nozzles are evenly distributed on the outer wall of the distribution pipe, ensuring uniform water and fertilizer coverage and significantly improving fertilization area and efficiency. The entire system uses a direct pipe connection, reducing the risk of leakage at the interfaces. Simultaneously, the water pump drives fluid circulation, making water and fertilizer transport smoother and overcoming the dependence on terrain inherent in traditional gravity flow methods. This makes it particularly suitable for the precision fertilization needs of large-area farmland and landscaping.

[0018] 2. The joint mechanism adopts a collaborative working mode of connecting sleeve, adjusting sleeve, transmission sleeve, mating block, mating rod, spiral groove, connecting plate, control sleeve, adjusting hole, and sealing sleeve. It innovatively solves the technical problem of precise adjustment of water and fertilizer spraying volume. By rotating the adjusting sleeve, the transmission sleeve is driven to rotate. The sliding motion of the mating block in the spiral groove is used to convert the rotational motion into the axial movement of the mating rod, thereby controlling the position of the polygonal control sleeve in the sealing sleeve and changing the number and area of ​​the opening of the adjusting holes. This design realizes the functional conversion of complex flow adjustment through simple rotation, and the operation is intuitive and convenient. The spiral groove and mating block are both designed with rounded corners, which reduces friction and wear between moving parts and improves adjustment accuracy and service life. The gradient closure design of multiple sets of adjusting holes makes the flow adjustment more precise and linear, meeting the refined needs of different crops and growth stages for water and fertilizer application, and effectively avoiding resource waste and environmental problems caused by over- or under-fertilization.

[0019] 3. The mixing mechanism consists of a rotating rod, a stirring frame, a screw rod, and a motor. It efficiently solves the key problem of uneven water and fertilizer mixing. The motor drives the rotating rod to rotate, which in turn drives the stirring frame and screw rod to perform a two-stage mixing operation. The stirring frame first performs preliminary mixing of the upper water and fertilizer, and then the screw rod performs deep mixing of the lower water and fertilizer. This double mixing structure accelerates the dissolution speed and uniformity of solid fertilizer in water. Attached Figure Description

[0029] Please see Figures 1-5 A spraying device includes a trolley 1 with a spraying mechanism mounted on it. The spraying mechanism includes a mounting shell 2, a mixing cylinder 3, a water pump 4, a delivery pipe 5, an output pipe 6, an adjusting mechanism, a diverter pipe 7, and a nozzle 8. The mounting shell 2 is fixed to the trolley 1, the mixing cylinder 3 is fixed to the bottom of the mounting shell 2, the water pump 4 is connected to the outer wall of the mixing cylinder 3, the delivery pipe 5 is fixed to the output end of the water pump 4, and the output pipe 6 is located at the top of the delivery pipe 5. The adjusting mechanism includes a connecting sleeve 9, an adjusting sleeve 10, a transmission sleeve 11, a mating block 12, a mating rod 13, a spiral groove 14, a connecting plate 15, a control sleeve 16, an adjusting hole 17, and a sealing sleeve 18. The connecting sleeve 9 is fixed to the delivery pipe. At the top of the 5th section, the adjusting sleeve 10 is rotatably connected to the connecting sleeve 9 and the output pipe 6. The transmission sleeve 11 is fixed inside the adjusting sleeve 10. Multiple sets of mating blocks 12 are distributed inside the transmission sleeve 11. The mating rod 13 is movable on the inner wall of the transmission sleeve 11. The spiral groove 14 is set on the outer wall of the mating rod 13 and is slidably connected to multiple sets of mating blocks 12. The connecting plate 15 is fixed at the bottom of the mating rod 13. The control sleeve 16 is set on the top surface of the connecting plate 15. Multiple sets of adjusting holes 17 are distributed on the outer wall of the control sleeve 16. The sealing sleeve 18 is set on the inner wall of the connecting sleeve 9 and is slidably connected to the outer wall of the control sleeve 16. The diverter pipe 7 is fixed at the top of the output pipe 6. The nozzle 8 is connected to the outer wall of the diverter pipe 7.

[0030] The top of the mounting housing 2 is fixedly equipped with a feed hopper 19. The feed hopper 19 uses a flared design to guide the material in, expand the feeding area to reduce splashing and waste, and the fixed connection ensures airtightness to prevent vibration and loosening.

[0031] A fixing bracket 20 is fixed to the outer wall of the mounting shell 2, and the bottom end of the fixing bracket 20 is fixed to the outer wall of the output pipe 6. The fixing bracket 20 connects the mounting shell 2 and the output pipe 6 through a triangular stabilizing structure, distributing the stress points to resist water pressure and vibration, and preventing pipe deformation and loosening of connections.

[0032] Multiple sets of nozzles 8 are distributed on the outer wall of the diversion pipe 7. The ring-shaped distribution of multiple sets of nozzles 8 achieves 360-degree spray coverage. The pressure equalization design inside the diversion pipe 7 ensures that the flow rate of each nozzle 8 is consistent, and the overlapping spray range eliminates blind spots.

[0033] The outer side of the control sleeve 16 is polygonal and slidably connected to the cover 18. The polygonal design of the control sleeve 16 and the cover 18 form an anti-rotation guide, ensuring that it does not rotate during axial movement, ensuring accurate positioning of the adjustment hole 17, increasing the contact area and improving the sealing effect.

[0034] Multiple sets of mating blocks 12 are all arc-shaped and slide within the spiral groove 14. The arc-shaped design of the mating blocks 12 forms a surface contact with the spiral groove 14, reducing unit pressure, decreasing wear, and improving sliding smoothness and transmission efficiency.

[0035] The spiral groove 14 and the outer sides of the multiple sets of mating blocks 12 are all provided with rounded corners. The rounded corner design eliminates stress concentration points, reduces fatigue risk, reduces sliding friction and jamming, extends component life, and maintains adjustment accuracy.

[0036] The mounting housing 2 houses a mixing mechanism, which includes a rotating rod 21, a stirring frame 22, a screw rod 23, and a motor 24. The rotating rod 21 rotates within the mounting housing 2, the stirring frame 22 is fixed to the bottom end of the rotating rod 21, the screw rod 23 is fixed to the bottom end of the stirring frame 22, and the motor 24 is fixed to the outside of the mounting housing 2 with its output end fixedly connected to the rotating rod 21. The motor 24 drives the rotating rod 21, the stirring frame 22 uses centrifugal force for upper coarse mixing, and the screw rod 23 provides downward thrust for fine mixing, forming a progressive three-stage mixing effect. The motor 24 is externally mounted to prevent corrosion from water and fertilizer.

[0037] In this embodiment, fertilizer raw materials and water are injected into the mounting shell 2 through the feed hopper 19. The motor 24 is started to drive the rotating rod 21 to rotate. The rotating rod 21 drives the mixing frame 22 and the screw rod 23 to rotate. The fertilizer raw materials and water are initially mixed by the mixing frame 22 and then flow into the mixing cylinder 3. The fertilizer is further mixed by the screw rod 23. Then, the water pump 4 is started to extract the water and fertilizer and deliver it to the diversion pipe 7 through the conveying pipe 5 and the output pipe 6. Finally, the water and fertilizer are sprayed through multiple sets of nozzles 8.

[0038] More specifically, when it is necessary to adjust the amount of water and fertilizer sprayed, the rotating adjustment sleeve 10 drives the transmission sleeve 11 to rotate. The transmission sleeve 11 drives multiple sets of mating blocks 12 to slide along the spiral groove 14, so that the transmission sleeve 11 and the mating rod 13 form a threaded engagement, thereby driving the mating sleeve to move longitudinally along the transmission sleeve 11. At the same time, it drives the connecting plate 15 and pushes the control sleeve 16 to slide along the sealing sleeve 18, thereby changing the number of sealing holes 17 blocked by the sealing sleeve 18, thereby adjusting the flow area of ​​water and fertilizer and adjusting the flow rate of water and fertilizer.

[0039] In summary, when the entire equipment is in use or running: fertilizer raw materials and water are injected into the mounting shell 2 through the feed hopper 19. The motor 24 is started to drive the rotating rod 21 to rotate. The rotating rod 21 drives the mixing frame 22 and the screw rod 23 to rotate. The fertilizer raw materials and water are initially mixed by the mixing frame 22 and then flow into the mixing drum 3. The fertilizer is further mixed by the screw rod 23. Then the water pump 4 is started to draw water and fertilizer and delivers it to the diversion pipe 7 through the conveying pipe 5 and the output pipe 6. Finally, the water and fertilizer are sprayed through multiple sets of nozzles 8.

[0040] When it is necessary to adjust the amount of water and fertilizer sprayed, the rotating adjustment sleeve 10 drives the transmission sleeve 11 to rotate. The transmission sleeve 11 drives multiple sets of mating blocks 12 to slide along the spiral groove 14, so that the transmission sleeve 11 and the mating rod 13 form a threaded engagement, thereby driving the mating sleeve to move longitudinally along the transmission sleeve 11. At the same time, it drives the connecting plate 15 and pushes the control sleeve 16 to slide along the sealing sleeve 18, thereby changing the number of sealing holes 17 blocked by the sealing sleeve 18, thereby adjusting the flow area of ​​water and fertilizer and adjusting the flow rate of water and fertilizer.
