Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering equipment technology, specifically to a water conservancy irrigation vehicle. Background Technology

[0002] Water conservancy irrigation refers to water conservancy measures that use artificial facilities to introduce water resources into farmland in order to provide sufficient water for crop growth, fully guarantee agricultural production, and increase crop yield. Water conservancy irrigation vehicles are equipment used to support mobile water conservancy irrigation operations. They can be used for water intake, water transportation, water distribution, and irrigation water, and can assist in the rational allocation and efficient utilization of water resources. For example, a water conservancy irrigation vehicle disclosed in Chinese Patent Publication CN221887343U can adjust the angle and height of the nozzles according to the environment and the height of the crops, which is highly flexible.

[0003] Existing technologies often have the following problems when used:

[0004] Traditional irrigation trucks mostly use a fixed spacing and fixed vertical angle spray structure. The spray range of the irrigation truck cannot be flexibly adjusted according to the different planting spacing of crops, and the fixed vertical spray angle is difficult to adapt to the irrigation needs of crops with different planting heights. This results in a mismatch between the coverage of the sprinkler irrigation and the needs of crop planting, leading to over-irrigation or under-irrigation in some planting areas. This not only wastes water resources, but may also affect the uniformity of crop growth. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a water conservancy irrigation vehicle, which can effectively solve the problem that the spraying range and spraying angle of the water conservancy irrigation vehicle in the existing technology are not easy to adjust, resulting in a mismatch between the coverage of the spraying irrigation and the demand, leading to over-irrigation or under-irrigation in some planting areas.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] This utility model provides a water conservancy irrigation vehicle, comprising:

[0008] An irrigation vehicle floor, wherein a water storage tank is fixedly connected to the upper surface of the irrigation vehicle floor;

[0009] A variable-pitch sprinkler assembly includes a support frame fixedly connected to the outer wall of a water storage tank. Splined shafts are rotatably connected to both ends of the support frame. A support frame is fixedly connected to the upper surface of the irrigation vehicle's floor plate. A sprinkler pipe is rotatably connected to the upper end of the support frame. The sprinkler pipe is connected to the water storage tank via a connecting pipe. Two sprinkler cylinders are slidably and sealingly connected to the inner wall of the sprinkler pipe. Several sprinkler through holes are provided on the side walls of both the sprinkler pipe and the sprinkler cylinders. Limiting sleeves are fixedly connected to the outer walls of both sprinkler cylinders. The two limiting sleeves are slidably connected to two splined shafts respectively. A variable-pitch drive component is rotatably connected to the inner wall of the support frame. The variable-pitch drive component is used to drive the two sprinkler cylinders to move horizontally.

[0010] An angle adjustment component is fixedly connected to the upper surface of the irrigation vehicle's bottom plate. The angle adjustment component is used to adjust the vertical spraying angle of the spray pipe and the two spray cylinders.

[0011] Furthermore, the connecting pipe is a telescopic metal flexible hose, and a water pump is fixedly installed at the connection between the water storage tank and the connecting pipe.

[0012] Furthermore, the variable pitch drive component includes a bidirectional lead screw rotatably connected to the inner wall of the support frame. Two guide blocks are threaded onto the bidirectional lead screw. A connecting frame is fixedly connected to the outer wall of each of the two guide blocks. The two connecting frames are rotatably connected to two limiting sleeves respectively. A stepper motor is fixedly installed on the outer wall of the support frame. The output end of the stepper motor is fixedly connected to the end of the bidirectional lead screw.

[0013] Furthermore, the angle adjustment assembly includes two bearing seats fixedly connected to the upper surface of the irrigation vehicle's bottom plate. Each of the two bearing seats is rotatably connected to a rotating shaft. A first synchronous pulley is fixedly connected to the outer wall of each of the two rotating shafts. A second synchronous pulley is fixedly connected to the outer peripheral wall of each of the two splined shafts. The two first synchronous pulleys are respectively connected to the two second synchronous pulleys via synchronous tracks. A dual-axis motor is fixedly installed on the upper surface of the irrigation vehicle's bottom plate. The two output ends of the dual-axis motor are respectively fixedly connected to the ends of the two rotating shafts.

[0014] Furthermore, a linear guide rail is fixedly connected to the inner side of the support frame, and both guide blocks are in contact with and slide with the linear guide rail.

[0015] Furthermore, several bottom wheels are fixedly installed on the lower end face of the irrigation vehicle's bottom plate.

[0016] The technical solution provided by this utility model has the following advantages compared with the known prior art:

[0017] This invention incorporates a variable-pitch spray assembly. By driving two guide blocks to move towards or away from each other, two limiting sleeves can be moved towards or away from each other, allowing the two spray cylinders to extend or retract relative to the spray pipe. This alters the overall spray spacing and spray range of the spray pipe and the two spray cylinders, enabling convenient adjustment of the spray range based on crop planting spacing. This avoids over-irrigation or under-irrigation in localized planting areas, ensuring full utilization of water resources and uniform crop growth.

[0018] This invention includes an angle adjustment component. By driving two splined shafts to rotate, the two spray cylinders and spray pipes can be tilted upwards or downwards by a certain angle, thereby realizing the vertical adjustment of the overall spray angle of the spray pipes and two spray cylinders to adapt to different planting heights of crops and meet the irrigation needs of crops at different planting heights.

Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] The present invention will be further described below with reference to the embodiments.

[0027] Example: Refer to Figures 1 to 4 A water conservancy irrigation vehicle, comprising:

[0028] The irrigation vehicle consists of a base plate 1 and a variable-pitch spray assembly 3. A water storage tank 2 is fixedly connected to the upper surface of the base plate 1, and several wheels 7 are fixedly installed on the lower surface of the base plate 1. The variable-pitch spray assembly 3 includes a support frame 31 fixedly connected to the outer wall of the water storage tank 2. Splined shafts 32 are rotatably connected to both ends of the support frame 31. A support frame 33 is fixedly connected to the upper surface of the base plate 1, and a spray pipe 34 is rotatably connected to the upper end of the support frame 33. The spray pipe 34 is connected to the water storage tank 2 via a connecting pipe 35, which is a telescopic metal flexible hose. A water pump is fixedly installed at the connection between the water storage tank 2 and the connecting pipe 35. Two spray cylinders 36 are slidably connected to the inner wall of the spray pipe 34. Several spray through holes 37 are opened on the side walls of both the spray pipe 34 and the spray cylinders 36. Limit sleeves 38 are fixedly connected to the outer walls of both spray cylinders 36. The sleeve 38 is slidably connected to two splined shafts 32 respectively. The inner wall of the support frame 31 is rotatably connected to a pitch-changing drive component 4. The pitch-changing drive component 4 is used to drive the two spray cylinders 36 to move horizontally. The pitch-changing drive component 4 includes a bidirectional lead screw 41 rotatably connected to the inner wall of the support frame 31. Two guide blocks 42 are threadedly connected to the bidirectional lead screw 41. The outer walls of the two guide blocks 42 are fixedly connected to connecting frames 43. The two connecting frames 43 are rotatably connected to two limiting sleeves 38 respectively. A stepper motor 44 is fixedly installed on the outer wall of the support frame 31. The output end of the stepper motor 44 is fixedly connected to the end of the bidirectional lead screw 41. The stepper motor 44 is a model 86BYGH850 stepper motor that supports high microstepping drive and high load capacity. A linear guide rail 6 is fixedly connected to the inner side of the support frame 31. The two guide blocks 42 are in contact with the linear guide rail 6 and slide in fit.

[0029] The stepper motor 44 drives the bidirectional lead screw 41 to rotate, so that the two guide blocks 42 can move towards or away from each other under the limiting action of the linear guide rail 6, and drive the two limiting sleeves 38 to move towards or away from each other, so that the two spray cylinders 36 can extend or retract relative to the spray pipe 34, thereby changing the overall spraying distance and spraying range of the spray pipe 34 and the two spray cylinders 36. This allows for easy adjustment of the spraying range according to the crop planting distance, avoiding over-irrigation or under-irrigation in local planting areas, ensuring full utilization of water resources and uniform crop growth.

[0030] Specifically, the stepper motor 44 can precisely control the rotation accuracy of the bidirectional lead screw 41, so that the guide block 42 can accurately drive the limit sleeve 38 and the spray cylinder 36 to move. After the spray cylinder 36 is moved and adjusted, some of the spray through holes 37 on the spray cylinder 36 can be precisely connected with some of the spray through holes 37 on the spray pipe 34 to ensure the spraying effect of the spray pipe 34.

[0031] Specifically, when the spray cylinder 36 extends to its limit relative to the spray pipe 34, the spray cylinder 36 is still not separated from the spray pipe 34, ensuring the normal operation of the overall spraying operation of the spray pipe 34 and the spray cylinder 36.

[0032] An angle adjustment assembly 5 is fixedly connected to the upper end face of the irrigation vehicle base plate 1. The angle adjustment assembly 5 is used to adjust the vertical spraying angle of the spray pipe 34 and the two spray cylinders 36. The angle adjustment assembly 5 includes two bearing seats 51 fixedly connected to the upper end face of the irrigation vehicle base plate 1. A rotating shaft 52 is rotatably connected to the upper end of each of the two bearing seats 51. A first synchronous wheel 53 is fixedly connected to the outer wall of each of the two rotating shafts 52. A second synchronous wheel 54 is fixedly connected to the outer peripheral wall of each of the two splined shafts 32. The two first synchronous wheels 53 are respectively connected to the two second synchronous wheels 54 through a synchronous track 55. A dual-shaft motor 56 is fixedly installed on the upper end face of the irrigation vehicle base plate 1. The two output ends of the dual-shaft motor 56 are respectively fixedly connected to the ends of the two rotating shafts 52. The model of the dual-shaft motor 56 is 86BYGH850D.

[0033] The rotating shaft 52 is driven to rotate by a dual-shaft motor 56, and the two splined shafts 32 are driven to rotate by the transmission cooperation of the first synchronous wheel 53, the synchronous track 55 and the second synchronous wheel 54. This allows the two spray cylinders 36 and the spray pipe 34 to rotate at a certain angle, thereby realizing the vertical adjustment of the overall spray angle of the spray pipe 34 and the two spray cylinders 36 to adapt to different planting heights of crops and meet the irrigation needs of crops at different planting heights.

[0034] Specifically, the wrap angle between the synchronous track 55 and the first synchronous pulley 53 and the second synchronous pulley 54 is greater than 120°. Since the larger the wrap angle, the larger the contact area between the synchronous track 55 and the first synchronous pulley 53 and the second synchronous pulley 54, the greater the friction force that can be transmitted. Therefore, it can improve the reliability and load-bearing capacity of the transmission and reduce the occurrence of slippage.

[0035] Specifically, when the limiting sleeve 38 moves, the spline shaft 32 can extend and retract relative to the limiting sleeve 38, and the spline shaft 32 can drive the limiting sleeve 38 to rotate synchronously when it rotates, so as to complete the adjustment of the rotation angle of the spray cylinder 36 and the spray pipe 34.

[0036] Specifically, the spray pipe 34 rotates on the upper end of the support frame 33, and the rotation axis of the spray pipe 34 is on the same axis as the rotation axes of the two splined shafts 32 and the two spray cylinders 36, so as to support the adjustment of the spray angle of the spray pipe 34.

[0037] The working principle of this utility model is as follows:

[0038] During the spraying operation, the water in the water tank 2 is pressurized by the water pump and then transported to the spray pipe 34 and spray cylinder 36 through the connecting pipe 35, and finally sprayed out through several spray holes 37.

[0039] If the spraying range is adjusted according to the planting spacing of crops, the stepper motor 44 can be started and driven to rotate the bidirectional lead screw 41, so that the two guide blocks 42 can move towards or away from each other under the limiting action of the linear guide rail 6, and drive the two limiting sleeves 38 to move towards or away from each other, so that the two spray cylinders 36 can extend or retract relative to the spray pipe 34, thereby changing the overall spraying spacing and spraying range of the spray pipe 34 and the two spray cylinders 36.

[0040] If it is necessary to adjust the vertical spraying angle according to the planting height of the crop, i.e., to spray upwards or downwards, the dual-axis motor 56 can be started. The dual-axis motor 56 drives the rotating shaft 52 to rotate, and the transmission cooperation of the first synchronous wheel 53, the synchronous track 55 and the second synchronous wheel 54 drives the two spline shafts 32 to rotate. This allows the two spray cylinders 36 and the spray pipe 34 to rotate at a certain angle, thereby realizing the vertical adjustment of the overall spraying angle of the spray pipe 34 and the two spray cylinders 36.

[0041] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of this utility model.
