Description

Technical Field

[0001] This application relates to the technical field of irrigation devices, and more specifically, to an irrigation device for barley cultivation. Background Technology

[0002] As an important food crop and raw material for the brewing industry, barley's yield and quality are directly affected by water management during its cultivation. Traditional furrow irrigation and flood irrigation methods result in significant water waste and easily lead to soil compaction. With the development of agricultural water-saving technologies, sprinkler irrigation and drip irrigation technologies have been widely used.

[0003] However, while common mobile sprinkler irrigation equipment, such as reel sprinklers or center-pivot sprinklers, has achieved mechanized operation, the inventors recognized that the height of its atomizing nozzles is usually fixed or inconvenient to adjust. During the entire growth period of barley, the plant height grows from a few centimeters in the seedling stage to nearly one meter in the heading stage. A fixed atomizing nozzle height is difficult to adapt to this change. If the atomizing nozzle is set too low, it is easy to cause mechanical damage and the spray coverage is limited; if it is set too high, the water droplet drift and evaporation loss is large, and the irrigation uniformity decreases.

[0004] To address the aforementioned issues, we provide an irrigation device for barley cultivation. Summary of the Invention

[0005] To address the problems mentioned in the background art, this application provides an irrigation device for barley cultivation.

[0006] The irrigation device for barley cultivation provided in this application adopts the following technical solution: An irrigation device for barley cultivation, comprising: The traction unit is used to pull the entire irrigation device forward. A mobile water tank is equipped with several support wheels at its bottom. Multiple micro pumps are installed on the mobile water tank. The top of each micro pump is connected to a fine-tuning water pipe via a flexible hose. An atomizing nozzle is installed at the bottom of the fine-tuning water pipe. The mobile water tank is fixedly equipped with a main shaft at both ends, and a swing arm is rotatably mounted on the main shaft. A support frame is installed between the extended ends of the two swing arms, and multiple fine-tuning water pipes are evenly arranged on the support frame. The swing arm is also equipped with a drive mechanism for driving the swing arm to rotate around the main shaft; The swing arm is also equipped with a leveling component, which is connected to the support frame and is used to keep the support frame horizontal during the rotation of the swing arm.

[0007] In some embodiments, the drive mechanism includes a servo motor mounted on the swing arm, and a drive gear is mounted on the output shaft of the servo motor; A front bearing is mounted on the main shaft and installed in the swing arm. A central gear that meshes with the drive gear is also mounted on the main shaft.

[0008] In some embodiments, a collar is also installed at the extended end of the swing arm, an outer end bearing is installed in the collar, an end shaft is fitted in the outer end bearing, and the end shaft is fixedly connected to the end of the support frame.

[0009] In some embodiments, the leveling assembly includes an auxiliary shaft rotatably mounted in the swing arm, the auxiliary shaft being disposed close to the end shaft, and the auxiliary shaft and the end shaft being fitted with meshing synchronous gears; Synchronous pulleys are also fixedly installed on the ends of the auxiliary shaft and the main shaft, and synchronous belts are driven on the two synchronous pulleys. A protective cover is also installed on the outer surface of the swing arm.

[0010] In some embodiments, the support frame has multiple mounting slots for accommodating the fine-tuning water pipe, and a baffle is detachably mounted on the open side of the mounting slot. The baffle cooperates with the mounting slot to form a fixing structure for fixing the fine-tuning water pipe.

[0011] In some embodiments, the baffle is fixed to the support frame by bolts.

[0012] In some embodiments, the interior of the mobile water tank is equipped with crisscrossing anti-wave plates, with equal spacing between adjacent anti-wave plates, and a slit in the middle of each anti-wave plate for water flow.

[0013] In some embodiments, the traction unit includes a frame with a towing frame mounted at the rear of the frame, the towing frame being connected to the mobile water tank.

[0014] In some embodiments, a water tank is also installed on the frame, a water pump is installed at the bottom of the water tank, and a water supply pipe is connected between the water pump and the mobile water tank.

[0015] In summary, in the technical solution of this application embodiment, when the servo motor drives the active gear to roll around the central gear, it can push the swing arm to rotate, thereby adjusting the height of the fine-tuning water pipe on the support frame. This facilitates accurate adjustment according to the height of the wheat seedlings. Furthermore, the leveling component can compensate for the support frame during the rotation of the swing arm, ensuring that the support frame remains horizontal at any swing arm angle and ensuring that the atomizing nozzle always sprays vertically downwards, greatly improving the irrigation quality. In the technical solution of this application embodiment, the crisscrossing wave deflectors divide the interior of the water tank into multiple small chambers. The water volume in each chamber is small, and its swaying amplitude and impact force are correspondingly reduced. At the same time, adjacent chambers are connected by slits, and the water can flow slowly between the chambers, but cannot form large-scale resonant swaying. This can effectively suppress the swaying of the water in the water tank, improve the driving stability of the mobile water tank, and ensure operational safety. Attached Figure Description

[0018] The following is in conjunction with the appendix Figures 1 to 6 The present invention will be described in further detail below.

[0019] In the description of this application, it should be understood that the terms "thickness," "upper," "top," "bottom," "inner," "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Therefore, features defined as "first" or "second" may explicitly or implicitly include one or more features. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0020] It should be noted that the accompanying drawings are schematic and not to scale. For clarity and convenience, the relative dimensions and proportions of the parts shown are exaggerated or reduced in size; all dimensions are merely illustrative and not limiting. Furthermore, the same reference numerals are used for the same structures, elements, or fittings appearing in more than two drawings to indicate similar features.

[0021] In related technologies, the height of the atomizing nozzles in common mobile sprinkler irrigation equipment is usually fixed or inconvenient to adjust. During the entire growth period of barley, the plant height grows from a few centimeters in the seedling stage to nearly one meter in the heading stage. A fixed atomizing nozzle height is difficult to adapt to this change. If the atomizing nozzle is set too low, it is easy to cause mechanical damage and the spray coverage is limited; if it is set too high, the water droplet drift and evaporation loss is large, and the irrigation uniformity decreases. Reference Figure 1 , Figure 5 As shown, the irrigation device of this application mainly includes two parts: a traction unit 1 and a mobile water tank 2. In this embodiment of the application, the traction unit 1 is used to pull the entire irrigation device to move in the field. It includes a frame 101, and a plurality of traction frames 102 are installed at the rear of the frame 101. These traction frames 102 are fixedly connected to the front side of the mobile water tank 2 to realize the towing of the traction unit 1 to the mobile water tank 2. Specifically, the traction frame 102 can adopt a triangular or trapezoidal structure to improve the connection strength. Each traction frame 102 is fixedly connected to the front side of the mobile water tank 2. To adapt to uneven ground in the field, the connection point between the traction frame 102 and the mobile water tank 2 can adopt a ball joint or universal joint structure, allowing the mobile water tank 2 to have a certain degree of pitch and tilt freedom relative to the traction part 1, ensuring that each support wheel 219 always maintains contact with the ground to form effective support; As a preferred option, the towing frame 102 and the mobile water tank 2 can be connected by a pin shaft, which facilitates quick assembly and disassembly. A water supply tank 103 is also installed on the frame 101. A water pump 105 is installed at the bottom of the water supply tank 103. The water pump 105 is connected to the mobile water tank 2 through a water supply pipe 104, which is used to replenish water online when the mobile water tank 2 is short of water, thereby extending the single operation time. During operation, when the water level in the mobile water tank 2 is lower than the set threshold (which can be detected by the liquid level sensor), the driver or the automatic control system starts the water pump 105 to pump the water in the replenishment water tank 103 into the mobile water tank 2 through the water replenishment pipe 104, thereby realizing online water replenishment operation.

[0022] Reference Figures 1 to 3 As shown, the mobile water tank 2 is used to store irrigation water. Several support wheels 219 are installed at its bottom. The support wheels 219 are preferably wide rubber wheels to reduce soil compaction. Multiple micro pumps 205 are installed on the mobile water tank 2. The number of micro pumps 205 can be determined according to the actual required irrigation width. Specifically, each micro pump 205 is connected to a fine-tuning water pipe 204 at its top via a hose 206. An atomizing nozzle is installed at the bottom of the fine-tuning water pipe 204. The hose 206 is made of flexible material, allowing the fine-tuning water pipe 204 to have a certain amount of room for movement. In addition, a main shaft 201 is fixedly installed at both ends of the mobile water tank 2. The main shaft 201 extends horizontally outward and a swing arm 202 is rotatably installed on the main shaft 201. A support frame 203 is installed between the extended ends of the two swing arms 202. The support frame 203 has a long strip structure and extends horizontally along the direction perpendicular to the forward direction. Multiple fine-tuning water pipes 204 are evenly arranged on the support frame 203 so that the atomizing nozzles are arranged at equal intervals along the length of the support frame 203 to form a sprinkler belt. The spacing between adjacent fine-tuning water pipes 204 can be set according to the coverage of the atomizing nozzles to ensure that the barley in the sprinkler belt area can be fully irrigated. A collar 211 is fixedly installed at the extended end of the swing arm 202. An outer end bearing 213 is installed in the collar 211. An end shaft 212 is fitted in the inner ring of the outer end bearing 213. One end of the end shaft 212 is fixedly connected to the inner ring of the outer end bearing 213, and the other end extends out of the collar 211 and is fixedly connected to the end of the support frame 203. With this structure, the support frame 203 can rotate freely relative to the swing arm 202, providing a degree of freedom of motion for the leveling component to achieve attitude adjustment. The setting of the collar 211 can play a protective and positioning role, ensuring the accuracy and stability of the installation position of the outer end bearing 213. In this embodiment, the outer end bearing 213 is preferably a deep groove ball bearing, which can bear radial and axial loads at the same time, ensuring that the support frame 203 can rotate flexibly when bearing the weight of the atomizing nozzle and water pipe. Reference Figure 2 , Figure 3 , Figure 6 As shown, a drive mechanism for driving the swing arm 202 to rotate around the main shaft 201 is installed on the swing arm 202. The angle between the swing arm 202 and the horizontal plane can be changed through the drive mechanism, thereby adjusting the height of the support frame 203 to adapt to the height changes of barley at different growth stages. Specifically, when the swing arm 202 rotates around the main shaft 201, the support frame 203 at its extended end will change its height. At this time, the atomizing nozzle can be moved above the wheat seedlings to facilitate irrigation of the wheat seedling leaves. On the other hand, for taller wheat seedlings, the atomizing nozzle can also be moved to the height of the wheat stalk. At this time, the leaves above the wheat stalk will form a natural shield to prevent the water mist from being blown away by the wind. In this embodiment of the application, the driving mechanism includes a servo motor 209 mounted on the swing arm 202, an active gear 210 fixedly mounted on the output shaft of the servo motor 209, a front bearing 207 mounted on the main shaft 201, and the outer ring of the front bearing 207 fixedly mounted in the end hole of the swing arm 202, so that the swing arm 202 can rotate freely relative to the main shaft 201. Specifically, a central gear 208 is also mounted on the main shaft 201. The central gear 208 is fixedly connected to the main shaft 201, meaning that the central gear 208 is fixed and does not rotate. The driving gear 210 meshes with the central gear 208. During operation, when the servo motor 209 starts, the drive gear 210 rotates. Since the central gear 208 is fixed, the drive gear 210 will revolve around the central gear 208 under meshing action, thereby driving the entire swing arm 202 to rotate around the main shaft 201. This gear meshing transmission method has the advantages of precise transmission ratio and strong load-bearing capacity. It can precisely control the rotation angle of the swing arm 202, and thus precisely adjust the height of the support frame 203. This allows for accurate control of the height of the fine-tuning water pipe 204 and the atomizing nozzle, so that they are close to the top of the wheat seedlings or reach the height of the wheat stalks for irrigation.

[0023] Reference Figure 3 , Figure 6 As shown, the swing arm 202 is also equipped with a leveling component, which is connected to the support frame 203. This component is used to keep the support frame 203 in a horizontal state during the rotation of the swing arm 202. The ingenuity of this design is that when the two swing arms 202 rotate synchronously, if the support frame 203 tilts accordingly, it will cause the direction of the atomizing nozzle to change, affecting the uniformity of irrigation. It may even cause the atomizing nozzle to tilt to one side and fail to effectively cover the plants. The introduction of the leveling component ensures that no matter what angle the swing arm 202 is at, the support frame 203 is always horizontal and the atomizing nozzle always sprays vertically downwards, thereby ensuring the irrigation effect.

[0024] Specifically, the leveling assembly includes an auxiliary shaft 214 rotatably mounted in the swing arm 202. The auxiliary shaft 214 is located close to the end shaft 212 and parallel to the end shaft 212. In addition, the auxiliary shaft 214 and the end shaft 212 are respectively fitted with meshing synchronous gears 215. The number of teeth and the module of the two synchronous gears 215 are exactly the same, thereby ensuring that the two rotate at the same speed and in opposite directions. Furthermore, a synchronous pulley 216 is fixedly installed on the end of the auxiliary shaft 214 and the main shaft 201. A synchronous belt 217 is driven on the two synchronous pulleys 216. The synchronous pulleys 216 and the synchronous belt 217 constitute a synchronous transmission mechanism, so that the auxiliary shaft 214 and the main shaft 201 maintain a fixed transmission ratio (1:1 in this embodiment). Therefore, the leveling component works as follows: When the servo motor 209 drives the swing arm 202 to rotate around the main shaft 201, the angle of the swing arm 202 relative to the main shaft 201 changes. Since the main shaft 201 is fixed, the synchronous wheel 216 installed at the end of the main shaft 201 is also fixed. The timing belt 217 connects the timing pulley 216 at the end of the main shaft 201 and the timing pulley 216 on the auxiliary shaft 214. When the swing arm 202 rotates, the position of the auxiliary shaft 214 relative to the main shaft 201 changes. However, due to the constraint of the timing belt 217, the auxiliary shaft 214 is forced to produce a compensating rotation opposite to the rotation direction of the swing arm 202. Specifically: Assume that the swing arm 202 rotates clockwise by an angle θ; The auxiliary shaft 214 moves clockwise together with the swing arm 202. However, since the timing belt 217 is connected to the fixed main shaft 201 timing pulley 216, the timing pulley 216 on the auxiliary shaft 214 is pulled by the timing belt 217, forcing the auxiliary shaft 214 to rotate counterclockwise relative to the swing arm 202 by an angle θ. The synchronous gear 215 on the auxiliary shaft 214 rotates counterclockwise by an angle θ. The synchronous gear 215 on the end shaft 212 that meshes with the synchronous gear 215 is driven to rotate clockwise by an angle θ. Thus, the end shaft 212 drives the support frame 203 to rotate clockwise by an angle θ; In summary, the clockwise rotation θ of the swing arm 202 will cause the support frame 203 to tend to tilt counterclockwise. However, through the aforementioned transmission chain, the support frame 203 is compensated for by a clockwise rotation θ. The two cancel each other out, so that the support frame 203 remains horizontal relative to the ground. Thus, no matter how the swing arm 202 rotates, the support frame 203 installed on it can always remain horizontal. This allows the atomizing nozzle at the bottom of the fine-tuning water pipe 204 to always spray vertically downwards, ensuring irrigation effect. Therefore, through this purely mechanical linkage design, the rotation angle of the swing arm 202 and the compensation angle of the support frame 203 are precisely matched, ensuring that the support frame 203 can maintain an absolutely horizontal state at any height. Compared with the electronic leveling scheme, this scheme does not require sensors and control algorithms, has a simple and reliable structure, and a fast response speed. It is especially suitable for the harsh working environment of agricultural machinery, effectively ensuring that the atomizing nozzle always sprays vertically downwards, and the irrigation uniformity is not affected by the change in the height of the support frame 203. On the other hand, a protective cover 218 is also installed on the outer side of the swing arm 202 to protect the transmission components such as the synchronous gear 215, synchronous pulley 216 and synchronous belt 217, and to prevent dirt, weeds and other debris from entering and affecting the transmission accuracy and life.

[0025] Reference Figure 2 , Figure 3 As shown, the front side of the support frame 203 is provided with multiple mounting slots 2031 for accommodating the fine-tuning water pipes 204, and the number of mounting slots 2031 corresponds one-to-one with the number of fine-tuning water pipes 204. Specifically, the mounting groove 2031 is U-shaped or semi-circular with its opening facing forward. A baffle 2032 is detachably installed on the opening side of the mounting groove 2031. The baffle 2032 and the mounting groove 2031 cooperate to form a fixing structure for fixing the fine-tuning water pipe 204. During installation, first place the fine-tuning water pipe 204 into the mounting groove 2031, then cover the opening side of the mounting groove 2031 with the baffle 2032, and fix the baffle 2032 to the support frame 203 with bolts. The inner shape of the baffle 2032 matches the outer shape of the fine-tuning water pipe 204, which can firmly press the fine-tuning water pipe 204 into the mounting groove 2031 to prevent it from loosening or falling off during operation. During use, if a single fine-tuning water pipe 204 is damaged or malfunctions, the baffle 2032 at the corresponding mounting slot 2031 can be loosened to remove and replace the damaged fine-tuning water pipe 204 without the need for complete disassembly. On the other hand, since the length of the swing arm 202 is fixed, the height variation range of the support frame 203 is limited. In order to further fine-tune the distance between the atomizing nozzle and the barley canopy, the extension length of the fine-tuning water pipe 204 in the installation groove 2031 can be adjusted, that is, the vertical distance of the bottom end of the fine-tuning water pipe 204 extending out of the bottom surface of the support frame 203 can be controlled. Specifically, when installing the fine-tuning water pipe 204, the axial position of the fine-tuning water pipe 204 in the installation groove 2031 can be appropriately adjusted according to the actual height of the current barley plant, so that the atomizing nozzle and the barley canopy maintain the optimal spraying distance, thereby further improving the adaptability to barley at different growth stages.

[0026] Reference Figure 4 As shown, the interior of the mobile water tank 2 is equipped with crisscrossing anti-wave plates 220; Specifically, the wave deflector 220 includes multiple longitudinal wave deflectors arranged in the longitudinal direction and multiple transverse wave deflectors arranged in the transverse direction. They intersect each other perpendicularly and divide the interior of the movable water tank 2 into multiple small chambers. The spacing between adjacent wave deflectors 220 is kept equal to ensure that the volume of each chamber is uniform. Furthermore, the middle of the wave deflector 220 is provided with slits for water to pass through. The function of these slits is to allow water to flow slowly between the chambers, so as to avoid excessive local water level differences due to the complete isolation of the wave deflector. The size design of the slits needs to take into account both the wave deflection effect and the smooth flow of water. During operation, when the traction unit 1 tows the mobile water tank 2 in the field, especially when starting, accelerating, turning, or driving on uneven ground, the water inside the mobile water tank 2 will shake violently. The shaking of the water will generate a huge impact force, impacting the side wall of the mobile water tank 2, affecting driving stability, and in severe cases, even causing the vehicle to overturn. The crisscrossing anti-surge plates 220 divide the interior of the mobile water tank 2 into multiple small chambers. The water volume in each chamber is small, and its shaking amplitude and impact force are correspondingly reduced. At the same time, the adjacent chambers are connected by slits, and the water can flow slowly between the chambers, but cannot form a large-scale resonant shaking. This structure can effectively suppress the shaking of the water inside the mobile water tank 2, improve the driving stability of the mobile water tank 2, and ensure operational safety.

[0027] As a preferred embodiment, this application may also integrate an intelligent control system to improve the level of automation; The control system specifically includes: The controller (such as a PLC or microcontroller) is installed in the cab of the traction unit 1. A height sensor is installed on the support frame 203 or the swing arm 202 to detect the height of the support frame 203 or the angle of the swing arm 202 in real time. A liquid level sensor is installed inside the mobile water tank 2 to monitor the remaining water volume in real time; The operation panel is used to input work parameters and display the work status; Its control logic is as follows: Automatic height adjustment function: The operator inputs the plant height information of the current barley variety, and the controller automatically calculates the required angle of the swing arm 202 according to the preset optimal height of the atomizing nozzle from the ground, and controls the servo motor 209 to drive the swing arm 202 to rotate to the target position. The leveling components work synchronously to ensure that the support frame 203 is always horizontal during the adjustment process. Automatic water replenishment function: When the liquid level sensor detects that the water level in the mobile water tank 2 is lower than the set threshold, the controller automatically starts the water pump 105 to replenish water. When the water level reaches the upper limit, the water replenishment automatically stops. Segmented irrigation function: For areas with different growth conditions, the controller can control the start and stop time and flow rate of the micro pumps 205 at different locations to achieve variable irrigation and further improve water resource utilization efficiency.
