Description

Technical Field

[0001] This utility model relates to the field of sprinkler irrigation technology, specifically to a sprinkler irrigation device for a sprinkler vehicle. Background Technology

[0002] In garden maintenance and crop cultivation, it is necessary to spray water or pesticides on lawns and trees regularly. Regular manual spraying is not only labor-intensive but also inefficient, making it difficult to meet the maintenance needs of large-scale gardens. Therefore, spraying trucks are gradually being used more widely in gardens.

[0003] However, the existing sprinkler trucks are often equipped with fixed sprinkler irrigation devices, which means that the spray angle is often not adjustable. In actual scenarios, the density of trees and green belts often varies in the height direction. If the spray angle is fixed, it may cause trees and green belts with low density to be over-irrigated, while trees and green belts with high density will not be irrigated enough, and the effect of uniform irrigation cannot be achieved. Summary of the Invention

[0004] This invention addresses the problem that existing sprinkler truck irrigation devices often have non-adjustable spray angles, limited applicability, and cannot achieve uniform irrigation. It provides a sprinkler truck irrigation device with multiple spray angles, and the angle adjustment is simple, which can adapt to the irrigation needs of different crop planting heights.

[0005] To solve the above problems, the technical solution of the present invention is:

[0006] A spraying and irrigation device for a spraying vehicle includes a first frame fixedly mounted on the spraying vehicle, and a spraying assembly, with a second frame provided between the first frame and the spraying assembly;

[0007] One end of the second frame is rotatably connected to the first frame, and the other end is fixedly connected to the spray assembly;

[0008] The second frame is provided with a support plate, one end of which is rotatably connected to the second frame and the other end is provided with at least one adjustment groove. The first frame or the spraying vehicle is provided with at least one support block.

[0009] There is a distance between the rotatable connection between the second frame and the support plate and between the second frame and the first frame; there is a height difference between the rotatable connection between the second frame and the support plate and the support block in the vertical direction, so that the adjustment groove can be locked on the support block to limit the rotation angle of the second frame, thereby adjusting the spraying angle of the spray assembly.

[0010] Using the above scheme, the second frame can drive the spraying assembly to rotate relative to the first frame, i.e., the spraying vehicle, thereby adjusting the spraying angle of the spraying assembly to adapt to the needs of various actual spraying scenarios; and by cooperating with the support plate and support block, the spraying angle of the spraying assembly can be limited to ensure the stability of the spraying assembly during operation, and the adjustment is simple.

[0011] Based on the above solution, the present invention can be further improved as follows.

[0012] Furthermore, one end of the second frame is rotatably connected to the first frame via a rotating assembly. The rotating assembly includes a first frame sleeve, a second frame sleeve, an insert shaft, and a locking block. The inner diameters of the first and second frame sleeves are the same and are respectively disposed on the first and second frames. The outer diameter of the insert shaft is the same as the inner diameter of the first and second frame sleeves. At least one locking hole is provided on both the first frame sleeve and the insert shaft.

[0013] Alternatively, corresponding insertion shaft holes can be directly opened on the first frame and the second frame, wherein the outer diameter of the insertion shaft is consistent with the inner diameter of the insertion shaft hole, and at least one locking hole is opened on the first frame and the insertion shaft respectively.

[0014] The locking hole and the locking block are identical in shape, allowing the locking block to be inserted into the locking hole to fix the insert shaft to the first frame, and allowing the second frame to rotate around the insert shaft. This gives the spray assembly multiple spray angles, effectively expanding the spray range of the spray assembly, and making it easy to operate.

[0015] Furthermore, the spray assembly includes a blowing unit and a spraying unit. The spraying unit includes a spraying frame fixedly connected to the second frame, a nozzle disposed on the spraying frame, and a water pipe communicating with the nozzle and providing a water source to the nozzle.

[0016] The blowing unit includes fan blades and a power assembly that powers the fan blades, which are used to diffuse the water mist sprayed from the nozzle in all directions.

[0017] By adopting the above-mentioned further solution, the setting of the blowing unit enables the water mist sprayed from the nozzle to spread in all directions, further increasing the spraying range of the spray assembly.

[0018] Furthermore, the power component is a motor, which transmits power to the fan blades;

[0019] Alternatively, the power assembly may include a pulley and a transmission structure, wherein the transmission structure includes a first drive shaft, a commutator, and a second drive shaft, wherein the first drive shaft drives the second drive shaft to rotate via the commutator; and the rotation axis of the pulley coincides with the rotation axis of the rotating assembly.

[0020] The second drive shaft is fixedly connected to the fan blades, and the end of the first drive shaft is provided with a pulley. The power of the spray truck is transmitted to the pulley through belt drive, and the pulley can rotate relative to the first drive shaft.

[0021] A locking block and a push ring are slidably disposed on the first drive shaft. The locking block is disposed between the push ring and the pulley. A locking block groove is opened on the side of the pulley corresponding to the locking block. The push ring can push the locking block to be locked in the locking block groove, so as to realize the transmission of power from the pulley to the first drive shaft.

[0022] By adopting the above-mentioned further solution, the corresponding drive method of the fan blades can be selected according to actual needs; at the same time, the pulley can rotate relative to the first drive shaft, so that when the pulley receives power from the spraying vehicle, it will not directly drive the first drive shaft to rotate. Only when the push block is locked in the block groove can the pulley drive the first drive shaft to rotate. This allows the operation of the fan blades to be controlled according to the actual spraying range, thereby controlling the effect of water mist diffusion sprayed by the spraying assembly, further ensuring the applicability of the spraying assembly.

[0023] Furthermore, the second frame includes a connecting frame and a first support frame in the shape of an inverted "U". Two rotating components are respectively provided on two symmetrical sides of the connecting frame, and the other side is fixedly connected to the spraying component. The rotation axes of the two rotating components are consistent.

[0024] The first support frame is positioned between the two symmetrical sides of the connecting frame and is used to support the transmission structure or motor.

[0025] The above-mentioned further solution involves two rotating components on each side of the connecting frame, with the rotation axes aligned. This helps to evenly distribute the force during rotation, reduce single-point stress, and ensure the balance and stability of the spray assembly during rotation.

[0026] Furthermore, the second frame also includes an "L"-shaped second support frame, a first reinforcing frame, and a second reinforcing frame;

[0027] One end of the second support frame is fixedly connected to the first support frame, and the other end is fixedly connected to the bottom of the spray assembly, further supporting the spray assembly;

[0028] The first reinforcing frame is mounted on the connecting frame to improve the strength of the first supporting frame;

[0029] One end of the second reinforcing frame is fixedly connected to the first reinforcing frame, and the other end is fixedly connected to the first support frame, in order to improve the overall strength of the second frame.

[0030] Furthermore, the first frame and the second frame are provided with an auxiliary locking structure, which includes a hook and a spring hand catch. The hook is located at the end of the second frame near the spray assembly, and the spring hand catch is located on the first frame or the spraying vehicle. When the spray assembly is rotated to the lowest position, the spring hand catch can lock the hook.

[0031] With the above-mentioned further solution, when the sprinkler assembly is rotated to be perpendicular to the ground, the spring-loaded hand catch can lock the hook, thereby providing additional fixation for the sprinkler assembly and ensuring stability during operation.

[0032] Furthermore, the spraying frame includes a first support plate with a central opening, a second support plate with a central opening, and a support plate connector in the shape of a pipe. The first support plate and the second support plate are respectively fixedly disposed on the outer circular surfaces at both ends of the support plate connector.

[0033] The nozzle is located on the outside of the first support plate, and the fan blade is located inside the support plate connector.

[0034] Furthermore, the spray assembly also includes baffles and a partition net;

[0035] There is a gap between the baffle and the first support plate and the two are fixedly connected. The nozzle is fixedly installed between the first support plate and the baffle and the nozzle outlet faces outward. The baffle is used to direct the airflow generated by the fan blades toward the nozzle.

[0036] The partition net is fixedly installed on the second support plate to prevent debris from entering the interior of the spray frame when the blowing unit blows air.

[0037] Furthermore, at least one of the nozzles is disposed at the edge of the first support plate, and the nozzles are disposed circumferentially or non-circumferentially, uniformly or non-uniformly, on the first support plate.

[0038] When the spraying frame is not circumferentially oriented, a protective plate is provided at the bottom.

[0039] With the above-mentioned further solution, the nozzles can be set circumferentially or non-circumferentially on the first support plate, and uniformly or non-uniformly, providing a flexible spraying mode to adapt to different operational needs. When the nozzles are set non-circumferentially, a protective plate is provided at the bottom of the spraying frame to prevent the nozzles from spraying water mist to the bottom of the spraying vehicle when the spraying assembly is rotated to be perpendicular to the ground, thus avoiding water waste, and to prevent soil splashed from the ground from entering the interior of the spraying frame.

[0040] The beneficial effects of this utility model through the above technical solution are as follows:

[0041] 1. In this utility model, the second frame can drive the spraying assembly to rotate relative to the first frame, i.e., the spraying vehicle, so that the spraying assembly has multiple spraying angles. This not only expands the spraying range of the spraying assembly, but also allows for the selection of appropriate spraying angles based on the dense distribution of trees and green belts, achieving a uniform irrigation effect. Furthermore, the additionally provided support plates and support blocks ensure the stability of the spraying assembly during rotation and operation.

[0042] 2. In this utility model, the setting of the blowing unit enables the water mist sprayed from the nozzle to spread in all directions, further increasing the spraying range of the spraying assembly; and the rotation of the fan blades in the blowing unit can be driven by a separately set power source, or it can be driven by the power of the spraying vehicle through the pulley. Since the rotation axis of the pulley is consistent with the rotation axis of the rotating assembly, even if the second frame drives the spraying assembly to rotate, the pulley can still transmit the power of the spraying vehicle, effectively ensuring the normal operation of the fan blades.

[0043] 3. In this utility model, the connecting frame and the second support frame in the second frame can effectively support the spraying component, thereby ensuring the stability of the spraying component during operation; by setting the first reinforcing frame and the second reinforcing frame, the stability of the second frame is ensured, thereby ensuring the stability of the entire spraying irrigation device.

[0044] 4. In this utility model, the baffle design can ensure that the airflow is effectively blown towards the nozzle, thereby improving the diffusion effect of water mist; and the mesh design can prevent debris from entering the spray frame when the blowing unit is working, thereby preventing debris from obstructing the airflow to the nozzle, further ensuring the diffusion effect of water mist.

[0045] 5. In this utility model, the circumferential or non-circumferential arrangement of the nozzles, and the uniform or non-uniform distribution of the nozzles, enable the spraying assembly to adapt to different irrigation needs and occasions; and by setting a baffle at the lower part of the spraying frame, it is possible to prevent the nozzles from spraying water mist onto the bottom of the spraying vehicle when the spraying assembly is rotated to be perpendicular to the ground, thus avoiding the waste of water resources.

Detailed Implementation

[0053] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0054] like Figures 1-6 As shown, a spraying irrigation device for a spraying vehicle includes a first frame 1 fixedly mounted on the spraying vehicle, and a spraying assembly 3. A second frame 2 is provided between the first frame 1 and the spraying assembly 3.

[0055] One end of the second frame 2 is rotatably connected to the first frame 1, and the other end is fixedly connected to the spray assembly 3;

[0056] The second frame 2 is provided with a support plate 5. One end of the support plate 5 is rotatably connected to the second frame 2, and the other end is provided with at least one adjustment groove 51. The first frame 1 or the spraying vehicle is provided with at least one support block 6.

[0057] There is a distance between the rotatable connection between the second frame 2 and the support plate 5 and the rotatable connection between the second frame 2 and the first frame 1; there is a height difference between the rotatable connection between the second frame 2 and the support plate 5 and the support block 6 in the vertical direction, so that the rotatable connection between the second frame 2 and the support plate 5, the rotatable connection between the second frame 2 and the first frame 1 and the support block 6 can form a stable triangular structure, so that the adjustment groove 51 can be locked on the support block 6 to limit the rotation angle of the second frame 2, thereby adjusting the spraying angle of the spray assembly 3.

[0058] In one possible implementation, one end of the second frame 2 is rotatably connected to the first frame 1 via a rotating assembly 4. The rotating assembly 4 includes a first frame sleeve 41, a second frame sleeve 42, an insert shaft 43, and a locking block 44. The inner diameters of the first frame sleeve 41 and the second frame sleeve 42 are the same, both being circular tubes, and they are respectively fixedly mounted on the first frame 1 and the second frame 2. The outer diameter of the insert shaft 43 is the same as the inner diameter of the first frame sleeve 41 and the second frame sleeve 42. At least one locking hole 45 is provided on both the first frame sleeve 41 and the insert shaft 43. The locking hole 45 can be a threaded hole, a through hole, a pin hole, etc., and its shape can be circular or polygonal.

[0059] In this embodiment, the locking hole 45 is a circular pin hole, and the locking block 44 is a cylindrical pin with a matching shape;

[0060] Alternatively, corresponding insertion shaft holes can be directly opened on the first frame 1 and the second frame 2, the outer diameter of the insertion shaft 43 is consistent with the inner diameter of the insertion shaft hole, and at least one locking hole 45 is opened on the first frame 1 and the insertion shaft 43 respectively.

[0061] The locking hole 45 and the locking block 44 have the same shape, so that the locking block 44 can be inserted into the locking hole 45 to fix the insert shaft 43 to the first frame 1, so that the second frame 2 can rotate around the insert shaft 43, i.e. the first frame 1, thereby realizing the angle adjustment of the spray assembly 3 and effectively expanding the spray range of the spray assembly 3.

[0062] In this embodiment, the second frame 2 is rotatably connected to the first frame 1 through the rotating component 4.

[0063] In one possible implementation, the spray assembly 3 includes a blowing unit 31 and a spraying unit 32. The spraying unit 32 includes a spraying frame 321 fixedly connected to the second frame 2, a nozzle 322 disposed on the spraying frame 321, and a water pipe 323 communicating with the nozzle 322 and providing a water source for the nozzle 322. The blowing unit 31 includes a fan blade 311 and a power assembly that provides power to the fan blade 311. The fan blade 311 is used to generate a directional airflow that blows towards the nozzle, thereby spreading the water mist sprayed from the nozzle 322 in all directions, further expanding the spraying range of the spray assembly 3.

[0064] As one possible implementation, the power component is an electric motor, which transmits power to the fan blades 311;

[0065] Alternatively, the power assembly may include a pulley 310 and a transmission structure, wherein the transmission structure includes a first drive shaft 312, a commutator 313, and a second drive shaft 314. The first drive shaft 312 drives the second drive shaft 314 to rotate through the commutator 313. The rotation axis of the pulley 310 coincides with the rotation axis of the rotating assembly 4, so that even if the second frame drives the spraying assembly to rotate, the pulley can still transmit the power of the spraying vehicle, effectively ensuring the normal operation of the fan blades.

[0066] The second drive shaft 314 is fixedly connected to the fan blade 311. The end of the first drive shaft 312 is provided with a pulley 310. The power of the spray truck is transmitted to the pulley 310 through belt drive. The pulley 310 can rotate relative to the first drive shaft 312, so that when the pulley 310 receives the power of the spray truck, it will not directly drive the first drive shaft 312 to rotate.

[0067] A locking block 315 and a push ring 316 are slidably disposed on the first drive shaft 312. This can be achieved by setting a sliding key or spline on the first drive shaft 312 to prevent the locking block 315 and the push ring 316 from rotating relative to the first drive shaft 312. The locking block 315 is disposed between the push ring 316 and the pulley 310. The pulley 310 has a locking block groove 317 on the side corresponding to the locking block 315. Only when the push ring 316 pushes the locking block 315 to be locked in the locking block groove 317 can the pulley 310 transmit power to the first drive shaft 312, thereby driving the fan blade 311 to rotate. The operation of the fan blade 311 can be controlled according to the actual spraying range, thereby controlling the effect of the water mist sprayed by the spray assembly 3 spreading in all directions.

[0068] In this embodiment, a push rod is fixedly provided on the push ring 316 to facilitate pushing the locking block 315.

[0069] As one possible implementation, the second frame 2 includes a connecting frame 21 in the shape of an inverted "U" and a first support frame 22. Two rotating components 4 are respectively provided on the two symmetrical sides of the connecting frame 21, and the other side is fixedly connected to the spraying component 3. The rotation axes of the two rotating components 4 are consistent, which helps to evenly distribute the force during rotation and reduce the force on a single point.

[0070] In this embodiment, the first support frame 22 is disposed between the two symmetrical sides of the connecting frame 21, and is used to support the transmission structure or motor.

[0071] As one possible implementation, the second frame 2 further includes an "L"-shaped second support frame 23, a first reinforcing frame 24, and a second reinforcing frame 25; one end of the second support frame 23 is fixedly connected to the first support frame 22, and the other end is fixedly connected to the bottom of the spray assembly 3, further supporting the spray assembly 3;

[0072] The first reinforcing frame 24 is disposed on the connecting frame 21 to improve the strength of the first supporting frame 22; one end of the second reinforcing frame 25 is fixedly connected to the first reinforcing frame 24, and the other end is fixedly connected to the first supporting frame 22 to improve the overall strength of the second frame 2.

[0073] In this embodiment, the first reinforcing frame 24 includes an inverted "V"-shaped side reinforcing body fixedly disposed on both symmetrical sides of the connecting frame 21, and a horizontal reinforcing body connecting the two side reinforcing bodies; the second reinforcing frame 25 is fixedly disposed between the horizontal reinforcing body and the first supporting frame 22.

[0074] As one possible implementation, the first frame 1 and the second frame 2 are provided with an auxiliary locking structure 7. The auxiliary locking structure includes a hook 71 and a spring hand buckle 72. The hook 71 is located at one end of the second frame 2 near the spray assembly 3, and the spring hand buckle 72 is located on the first frame 1 or the spraying vehicle. When the spray assembly 3 is rotated to the lowest position, the spring hand buckle 72 can lock the hook 71, thereby providing additional fixing for the spray assembly 3.

[0075] In this embodiment, the hook 71 is located at one end of the connecting frame 21 near the spray assembly 3, and the spring hand buckle 72 is located on the first frame 1.

[0076] As one possible implementation, the spraying frame 321 includes a first support plate 324 with a central opening, a second support plate 325 with a central opening, and a support plate connector 326 in the shape of a pipe. The first support plate 324 and the second support plate 325 are respectively fixedly disposed on the outer circular surfaces at both ends of the support plate connector 326.

[0077] The nozzle 1 is located on the outside of the first support plate 324, that is, on the side away from the second support plate 325. The fan blade 311 is located inside the support plate connector 326 and is used to generate directional airflow so that the airflow can be blown through the support plate connector 326 to the side of the first support plate 324, that is, the nozzle 322.

[0078] As one possible implementation, the spray assembly 3 further includes a baffle 33 and a partition net 34;

[0079] There is a gap between the baffle 33 and the first support plate 324 and the two are fixedly connected. The nozzle 322 is fixedly disposed between the first support plate 324 and the baffle 33 and the nozzle 322 spray outlet faces outward. The baffle 33 is used to blow the airflow generated by the fan blade 311 toward the nozzle 322.

[0080] The partition net 34 is fixedly mounted on the second support plate 325, and the partition net 34 has a mesh structure.

[0081] Alternatively, the partition 34 may be a mesh structure composed of one or more ring rods and strip rods. When there are multiple ring rods, the multiple ring rods have different diameters and are concentrically fixed on the strip rods. The strip rods are fixedly connected to the second support plate 325. The partition 34 has an opening for the second drive shaft 314 to pass through. The partition 34 is used to prevent debris from entering the interior of the spray frame 321 when the blowing unit 31 blows air.

[0082] In this embodiment, the partition 34 is a mesh structure composed of ring rods and strip rods.

[0083] As one possible implementation, at least one of the nozzles 322 is disposed at the edge of the first support plate 324, and the nozzles 322 are disposed circumferentially or non-circumferentially, uniformly or non-uniformly, on the first support plate 324.

[0084] When the spray frame 321 is not circumferentially set, a protective plate 8 is provided at the lower part of the spray frame 321. This can prevent the nozzle 322 from spraying water mist to the bottom of the spray vehicle when the spray assembly 3 is rotated to be perpendicular to the ground, thus avoiding water waste. It also prevents mud splashed on the ground from entering the interior of the spray frame 321 and prevents the airflow generated by the blowing unit 31 from escaping from the bottom of the spray frame 321, thus affecting the diffusion effect of the water mist.

[0085] In this embodiment, six or eight nozzles are arranged non-circumferentially and non-uniformly around the center of the first support plate 324 at its edge, and the guard plate 8 is fixedly disposed at the lower part of the first support plate 324 and the baffle 33.

[0086] The preferred embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Any equivalent or equivalent modifications or substitutions to the technical solutions of the present utility model without departing from the spirit of the present utility model or the scope of disclosure shall fall within the protection scope of the present utility model.
