Description

Technical Field

[0001] This invention relates to the field of sprayer technology, and more specifically, to a vehicle-mounted swing-type sprayer. Background Technology

[0002] my country's facility agriculture has developed rapidly in recent years, achieving remarkable results in greenhouse construction, seedling technology, and conservation tillage. Its planting area and crop yield have remained among the highest in the world, and it has become an important global supplier, especially in vegetable and fruit production.

[0003] As an indispensable piece of agricultural machinery in modern agricultural production, sprayers play a crucial role in pest and disease control and crop growth promotion. Their efficiency and effectiveness directly impact the yield and quality of agricultural products, making them a hot research topic in the field of agricultural machinery. However, plant protection in my country's facility agriculture still faces numerous challenges: on the one hand, the high temperature and humidity of the facility environment provides a breeding ground for pests and diseases, significantly increasing the difficulty of control; on the other hand, although my country's plant protection machinery industry has advantages in market size and policy support, there is still a significant gap compared to international advanced levels in core technologies, high-end equipment, and environmental standards. Currently, spraying in greenhouses still heavily relies on manual operation, with a low level of mechanization. Even existing small sprayers cannot achieve all-around spraying, with pesticide utilization rates of only 20%-30%, resulting not only in resource waste but also health risks due to operators' direct contact with pesticides.

[0015] The beneficial effects of this invention are as follows: In this invention, during operation, the carrier vehicle moves slowly within the greenhouse passageway, while the rotating support rotates horizontally under the drive of the drive device, causing the spray pipe assembly to rotate synchronously and expanding the lateral spraying range. Simultaneously, the swing connecting rod, under the action of the drive component, swings up and down in the vertical plane around its hinge point with the rotating support, pulling or pushing the air supply hose to bend regularly, causing the spray nozzle of the spray pipe to form a certain swing angle in the vertical direction, achieving full coverage spraying of crops at different heights.

[0016] The combination of the horizontal rotation of the rotating bracket and the vertical swing of the swing connecting rod breaks the fixed directional limitation of the spraying range, and can adapt to the spraying needs of crops with different row spacing and different heights in the greenhouse, reducing the amount of manual re-spraying and improving work efficiency.

[0024] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0025] like Figures 1-8As shown, this invention illustrates a vehicle-mounted swing-type sprayer according to an embodiment of the present invention, comprising a carrier body 1 and a rotating support 2. The rotating support 2 is mounted on the carrier body 1, and a swing connecting rod 4 is hinged to the rotating support 2. The swing connecting rod 4 can swing in a vertical plane about the hinge point with the rotating support 2. A spray pipe assembly 6 is mounted on the rotating support 2 and can rotate synchronously with the rotating support 2 in a horizontal plane. The spray pipe assembly 6 has an air supply hose 32, which is hinged to the end of the swing connecting rod 4 away from the rotating support 2. When the swing connecting rod 4 swings about the hinge point with the rotating support 2, the swing connecting rod 4 can pull or push the air supply hose 32 to bend, thereby driving the spray nozzle of the spray pipe to swing in a vertical plane.

[0026] For example, such as Figure 1 As shown, the vehicle-mounted swing-type sprayer's carrier body 1 can be a remote-controlled mobile trolley with a mounting platform or a trailer frame, facilitating flexible movement in narrow passages. The slewing bracket 2 is bolted to the middle of the carrier body 1, and its top is equipped with a hinged seat with bearings. One end of the swing connecting rod 4 is connected to this hinged seat by a pin, and the other end is connected to the air supply hose 32 of the spray pipe assembly 6 via a universal joint. The air supply hose 32 is made of high-strength, wear-resistant rubber, with spiral steel wire embedded in the hose wall to enhance its bending resistance.

[0027] Specifically, during operation, the carrier vehicle 1 moves slowly within the greenhouse passageway, while the rotating support 2 rotates horizontally under the drive of the drive unit, causing the spray pipe assembly 6 to rotate synchronously, expanding the lateral spraying range. Simultaneously, the swing connecting rod 4, under the action of the drive unit, swings up and down in the vertical plane around its hinge point with the rotating support 2, pulling or pushing the air supply hose 32 to bend regularly, causing the spray nozzle of the spray pipe to form a certain swing angle in the vertical direction, achieving full coverage spraying of crops at different heights.

[0028] The combination of the horizontal rotation of the rotating bracket 2 and the vertical swing of the swing connecting rod 4 breaks the fixed direction limitation of the spraying range, can adapt to the spraying needs of crops with different row spacing and different heights in the greenhouse, reduce the amount of manual re-spraying, and improve the work efficiency.

[0029] In some examples, the slewing bracket 2 includes a slewing support 21 and a mounting bracket 22. The mounting support is located at the movable end of the slewing support 21, and the mounting bracket 22 can rotate with the slewing support 21 in the horizontal plane. The swing connecting rod 4 is hinged to the top of the mounting bracket 22, and the swing connecting rod 4 can swing about the hinge point with the mounting bracket 22 in the vertical plane.

[0030] For example, such as Figure 1As shown, the slewing support 21 adopts a worm gear driven turntable structure. The worm gear is fixed to the bottom of the turntable, and the worm is connected to the drive motor. The whole structure is fixed to the chassis of the carrier body 1 by bolts. The turntable serves as the movable end of the slewing support 21. Its top surface is rigidly connected to the mounting frame 22 through a flange, and a sealing gasket is added between the connecting surfaces to enhance stability. The mounting frame 22 is a frame structure. Two symmetrically distributed hinged lugs are welded to the top crossbeam of the frame. An installation gap is reserved between the lugs to accommodate the swing connecting rod 4. The end of the swing connecting rod 4 is hinged to the lug through a deep groove ball bearing, and the hinge shaft is arranged in the horizontal direction to ensure that the swing connecting rod 4 can swing flexibly and smoothly in the vertical plane without any jamming.

[0031] When the horizontal direction of the spray needs to be adjusted, the drive device drives the turntable of the slewing support 21 to rotate, and the mounting frame 22 rotates synchronously with the turntable, thereby causing the swing connecting rod 4 and the spray pipe assembly 6 on the mounting frame 22 to change their horizontal orientation. During the spraying process, the slewing support 21 can achieve a certain angle of directional rotation according to the crop planting row direction, and cooperate with the movement of the carrier vehicle 1 to complete the continuous spraying of multiple rows of crops.

[0032] The separate structure of the slewing support 21 and the mounting bracket 22 facilitates later maintenance and component replacement. The frame structure of the mounting bracket 22 has high strength and can stably support components such as the spray pipe assembly 6, preventing swaying during swinging and rotation, and ensuring the stability and accuracy of spraying.

[0033] In some examples, the vehicle body 1 is equipped with a liquid tank 5 and a blower 7. The spray pipe assembly 6 includes a fixed pipe 31, which is mounted on a mounting bracket 22. One end of the fixed pipe 31 is connected to the air outlet of the blower 7, and the other end is connected to an air supply hose 32. An air outlet guide tube 33 is located at the end of the air supply hose 32 away from the fixed pipe 31 and is connected to the air supply hose 32. The air outlet guide tube 33 has an exhaust port 310. An annular nozzle 60 is mounted on the air outlet guide tube 33 and located at the exhaust port 310. The annular nozzle 60 and the air outlet guide tube 33 are coaxially arranged and are connected to the liquid tank 5. The air outlet guide tube 33 is used to spray the liquid medicine sprayed by the annular nozzle 60.

[0034] For example, such as Figure 2As shown, a medicine tank 5 is installed at the rear of the carrier body 1, made of corrosion-resistant and lightweight material. The fan 7 is a centrifugal fan, fixed to the front of the carrier body 1, with its outlet connected to one end of a fixed pipe 31 via a corrugated metal pipe. The fixed pipe 31 is a rigid pipe, fixed in the mounting bracket 22 with pipe clamps, and its other end connected to the air supply hose 32. The air outlet guide tube 33 has a conical or cylindrical structure, with one end connected to the air supply hose 32 and the other end serving as an exhaust port 310, made of lightweight material. The annular nozzle 60 is fixed to the exhaust port 310 by a bracket, coaxial with the air outlet guide tube 33, and its inlet is connected to the infusion pump at the bottom of the medicine tank 5 via a high-pressure resistant hose.

[0035] During operation, the infusion pump delivers the pesticide solution from the pesticide tank 5 to the annular nozzle 60, where it is sprayed out as a mist. Simultaneously, the fan 7 starts, generating a high-pressure airflow that passes through the fixed pipe 31 and the air supply hose 32 into the exhaust guide tube 33, and is then ejected at high speed from the exhaust port 310. This airflow carries the mist from the annular nozzle 60, creating a wider-ranging and more penetrating spray that reaches the crop leaves and branches. Under the action of the swing connecting rod 4, the exhaust guide tube 33 swings up and down, ensuring the mist evenly covers the upper, middle, and lower parts of the crop.

[0036] The high-pressure airflow from the fan 7 assists in pesticide delivery, allowing the pesticide droplets to adhere more evenly to the crop surface, especially to areas that are difficult to reach with traditional spraying, such as the undersides of leaves, thus improving pesticide utilization. The coordinated design of the annular nozzle 60 and the air outlet guide tube 33 reduces pesticide drift loss and minimizes pollution to the greenhouse environment.

[0037] In some examples, the annular nozzle 60 includes an annular water supply pipe 61, which is located at the exhaust port 310 of the air outlet guide tube 33 and is coaxially arranged with the air outlet guide tube 33; there are several nozzles 62, which are spaced apart on the annular water supply pipe 61 and communicate with the annular water supply pipe 61, and all the nozzles 62 face the axial side of the annular water supply pipe 61, and are arranged at an angle away from the annular water supply pipe 61 and away from the air outlet guide tube 33.

[0038] For example, such as Figure 3 As shown, the annular water supply pipe 61 is fixed to the edge of the exhaust port 310 of the air outlet guide tube 33 by multiple evenly distributed supports, and remains coaxial with the air outlet guide tube 33. The nozzles 62 are made of corrosion-resistant material, are numerous, and are evenly distributed along the circumference of the annular water supply pipe 61. The nozzles 62 face the axial side of the annular water supply pipe 61 and are arranged at an angle away from the air outlet guide tube 33.

[0039] After being pressurized by the infusion pump, the liquid medicine enters the annular water delivery pipe 61 and is sprayed out from the nozzle 62 under pressure. Since the nozzle 62 faces the axis of the annular water delivery pipe 61 and is tilted outward, the sprayed liquid medicine droplets converge in the annular area and are then pushed forward by the high-pressure airflow discharged from the air outlet guide tube 33. At the same time, the annular spray surface formed by multiple nozzles 62 forms a suitable angle with the airflow direction, which further refines the droplets and makes them evenly distributed in the airflow.

[0040] The annular spray formed by multiple inclined nozzles 62 can fully mix with the high-pressure airflow, resulting in smaller and more uniform droplet diameters of the pesticide solution, thus improving the adhesion rate of the pesticide solution to the crop surface. The inclined angle design of the nozzles 62 avoids the pesticide solution from being directly sprayed onto the inner wall of the air outlet guide tube 33, thus preventing waste and further improving the pesticide utilization rate.

[0041] In some examples, the medicine tank 5 is equipped with a stirring mechanism 8 for stirring the medicine solution. The stirring mechanism 8 includes a fixed toothed disc 82, which is located at the top of the medicine tank 5; a limiting support 86 is located inside the medicine tank and in the middle of the tank, with a spherical hinge seat 87 at the center of the limiting support 86; and a stirring rod 83, with a gear 84 at one end near the driving toothed disc. The gear 84 meshes with the fixed toothed disc 82 and can rotate around the fixed toothed disc 82. The rod of 83 passes through the spherical hinge seat 87 and is fixedly connected to the spherical hinge seat 87. The stirring rod 83 is arranged at an angle. The driver 81 is set at the top of the medicine tank 5. The power output end of the driver 81 passes through the top surface of the medicine tank 5 and the fixed toothed disc 82. The power output end of the driver 81 is fixedly connected to the connecting rod 85. The end of the connecting rod 85 away from the stirring rod 83 is sleeved with the rod body of the stirring rod 83. The connecting rod 85 is used to drive the stirring rod 83 to rotate around the spherical hinge seat 87.

[0042] For example, such as Figure 4 As shown, the fixed gear 82 is a ring gear 84 structure, fixed to the top center of the medicine tank 5 with bolts, and the tooth surface facing downwards. The limiting support 86 is a cylindrical structure, fixed in the middle position inside the medicine tank 5, and the spherical hinge seat 87 at its center is made of wear-resistant material, enabling multi-angle rotation. The stirring rod 83 is a metal rod with a small gear 84 meshing with the fixed gear 82 installed at its upper end. The middle part of the rod passes through the spherical hinge seat 87 and is fixed thereto, and the whole is arranged at an angle. The driver 81 is installed on the top of the medicine tank 5, and its output shaft passes through the top surface of the medicine tank 5 and the fixed gear 82. The output end is fixedly connected to a connecting rod 85. The end of the connecting rod 85 away from the stirring rod 83 is sleeved with the rod body of the stirring rod 83, which is used to drive the stirring rod 83 to rotate around the spherical hinge seat 87.

[0043] When the driver 81 starts, its output shaft drives the connecting rod 85 to rotate, and the connecting rod 85 in turn drives the stirring rod 83 to rotate around the spherical hinge seat 87. Since the pinion 84 at the upper end of the stirring rod 83 meshes with the fixed gear plate 82, while the stirring rod 83 rotates around the center, the pinion 84 rolls along the tooth surface of the fixed gear plate 82, causing the stirring rod 83 to generate a compound motion of revolution and rotation. This drives the stirring rod 83 to perform multi-angle and large-range stirring actions in the medicine tank 5, ensuring that the medicine is fully mixed.

[0044] The combined motion of the stirring rod 83 effectively prevents pesticide sedimentation and stratification, making it especially suitable for pesticide formulations prone to stratification. This ensures uniform concentration of the sprayed solution and improves pest and disease control. The spherical hinge seat 87, in conjunction with the inclined stirring rod 83, ensures that the stirring range covers most of the pesticide tank 5, reducing dead zones in the stirring process.

[0045] In some examples, a stirring frame 88 is provided at the end of the stirring rod 83 away from the gear 84, and stirring blades 89 are provided on the stirring frame 88, with the stirring blades 89 arranged circumferentially on the stirring frame 88.

[0046] For example, such as Figure 5 As shown, the stirring frame 88 is a frame structure, welded to the end of the stirring rod 83 away from the gear 84, and is made of corrosion-resistant metal material. Several stirring blades 89 are arranged in two groups, each set at one end of the stirring frame 88, and are evenly distributed along the circumference. The blades are metal plates, inclined at a certain angle to the plane of the stirring frame 88.

[0047] When the stirring rod 83 rotates, the stirring frame 88 revolves and rotates along with the stirring rod 83, and the stirring blades 89 rotate in the liquid medicine. Because the blades are at an inclined angle, they will generate upward and lateral thrust on the liquid medicine during the rotation, forming vertical convection and circumferential circulation, which makes the liquid medicine form a complex flow state in the tank and accelerates the mixing process.

[0048] The combination of the mixing rack 88 and multiple blades increases the contact area with the pesticide solution, improving mixing efficiency. The tilt angle of the blades creates multidimensional flow of the pesticide solution, enhancing mixing uniformity, especially enabling rapid mixing of newly added pesticides and water, shortening preparation time and improving operational efficiency.

[0049] In some examples, the stirring blade 89 includes a first stirring blade 891, which is disposed on the outside of the stirring frame 88 and has a turbulence hole 892; and a second stirring blade 893, which is disposed on the inside of the stirring frame 88 and has a liquid passage hole 894.

[0050] For example, such as Figure 6As shown, the first stirring blade 891 is installed on the outer end of the stirring frame 88. The blade has a large area and a turbulence hole 892 is formed on its surface. The second stirring blade 893 is installed on the inner side of the stirring frame 88, close to the stirring rod 83. The blade has a small area and a liquid passage hole 894 is formed on its surface.

[0051] When the stirring frame 88 rotates, the first stirring blade 891 moves in the outer area of ​​the liquid tank 5. The turbulence holes 892 on its surface allow some of the liquid to pass through the blade, generating eddies at the edge of the holes and breaking the laminar flow of the liquid. The second stirring blade 893 moves in the central area of ​​the liquid tank 5. The liquid passage holes 894 allow the liquid to flow on both sides of the blade, reducing stirring resistance while promoting the exchange of liquid between the central and outer areas.

[0052] The turbulence holes 892 and 894 enhance the turbulence of the liquid, further improving the uniformity of mixing while reducing energy consumption during the mixing process. The coordinated operation of the first and second blades ensures that the liquid in different areas of the liquid tank 5 is fully mixed, avoiding uneven mixing caused by the large volume of the liquid tank 5.

[0053] In some examples, a deflection seat 9 is provided on the mounting bracket 22. The deflection seat 9 includes a mounting plate 91, which is disposed on the outer side wall of the mounting bracket 22. A drive gear 92 is rotatably disposed on the mounting plate 91. A driven gear 93 is rotatably disposed on the mounting bracket 22 and meshes with the drive gear 92. A swing connecting rod 4 is disposed on the driven gear 93.

[0054] For example, such as Figure 5 As shown, the mounting plate 91 is a metal plate, vertically mounted on the outer wall of the mounting frame 22. A drive gear 92 is rotatably mounted on the plate surface, driven by a driving component. A driven gear 93 is rotatably mounted on the mounting frame 22 and meshes with the drive gear 92. A swing connecting rod 4 is mounted on the driven gear 93.

[0055] When the drive unit starts, it drives the driving gear 92 to rotate, and the driving gear 92 drives the driven gear 93 to rotate. Since the swing connecting rod 4 is connected to the eccentric position of the driven gear 93, the rotation of the driven gear 93 will be converted into the reciprocating swing of the swing connecting rod 4 around the hinge point. Its swing angle can be adjusted by the rotational speed of the driving gear 92 and the gear ratio of the driven gear 93.

[0056] The gear 84 transmission method allows for precise control of the swing angle of the swing connecting rod 4, facilitating the adjustment of the swing range of the spray nozzle assembly 6 according to the crop height and improving the targeting of pesticide spraying. The drive component ensures the smoothness of the swing action, avoiding uneven distribution of pesticide mist due to excessive swing speed. At the same time, the gear 84 transmission has high reliability and is suitable for long-term operation in the dusty environment of greenhouses.

[0057] In some examples, the mounting bracket 22 is provided with a clearance groove 221, which provides room for the bending action of the air supply hose 32.

[0058] For example, such as Figure 1 As shown, the mounting bracket 22 has a clearance groove 221, which is a long, narrow groove with rounded edges to prevent scratching the air supply hose 32. The clearance groove 221 is positioned corresponding to the bending path of the air supply hose 32, ensuring that the hose can smoothly pass through the groove at its maximum swing angle. When the swing connecting rod 4 causes the air supply hose 32 to bend up and down, the part of the hose in contact with the mounting bracket 22 will enter the clearance groove 221. The groove provides ample space for the hose to move, preventing the mounting bracket 22 from obstructing or squeezing the hose's bending action. During the rotation of the rotating support 2, the clearance groove 221 also prevents the hose from getting tangled or colliding with other parts of the mounting bracket 22. The clearance groove 221 effectively solves the problem of interference between the air supply hose 32 and the mounting bracket 22 during swinging and rotation, protecting the hose from mechanical damage and extending its service life. At the same time, it ensures that the swing connecting rod 4 can achieve its maximum swing angle, ensuring that the spraying range is not limited and improving the reliability of the equipment.

[0059] In some examples, a handle groove 51 is provided on the outer wall of the medicine tank 5, and the handle groove 51 is used to lift the medicine tank 5.

[0060] For example, such as Figure 1 As shown, handle grooves 51 are provided on the outer walls of both sides of the liquid tank 5, in several numbers, symmetrically distributed vertically. The handle grooves 51 are rectangular recesses with an anti-slip structure on the inner wall and rounded edges. The position of the handle grooves 51 is symmetrical with the center of gravity of the liquid tank 5, facilitating balance during handling. When moving or replacing the liquid tank 5, the operator can place both hands into the handle grooves 51, grasp the inner wall, and use arm strength to lift the liquid tank 5. The anti-slip structure increases the friction between the hand and the tank, preventing slippage during handling and protecting the operator's safety. When adding pesticides or water to the liquid tank 5, the handle grooves 51 can also serve as temporary grips, facilitating movement and repositioning of the liquid tank 5. The handle grooves 51 make the handling of the liquid tank 5 more convenient and labor-saving, especially in environments with limited space such as greenhouses where hoisting equipment is difficult to use, significantly improving the ease of loading, unloading, and cleaning of the liquid tank 5. The anti-slip structure enhances operational safety, preventing pesticide leakage caused by the liquid tank 5 tipping over due to slipping hands, and reducing the risk of environmental pollution.
