Description

Technical Field

[0001] This utility model relates to the field of sprinkler irrigation devices, and in particular to a foliar sprinkler irrigation device for tobacco cultivation. Background Technology

[0002] Tobacco, belonging to the Solanaceae family, is an annual herbaceous plant widely cultivated throughout my country. It is a crucial economic crop in my country, ranking first in the world in both planting area and annual output. Although the area under tobacco cultivation is relatively small compared to other crops in my country, the tobacco industry is highly profitable and a major source of national revenue. Tobacco cultivation requires sprinkler irrigation, which necessitates the use of sprinkler systems.

[0003] Existing sprinkler irrigation devices typically have nozzles fixedly mounted on supports, and the spacing between adjacent nozzles cannot be dynamically adjusted. This makes it impossible to adjust the coverage area according to the planting spacing or growth stage of tobacco plants. The sprinkler irrigation devices lack flexibility and are difficult to adapt to changes in tobacco planting density and plant spacing, resulting in uneven irrigation coverage. Some areas are over-irrigated while others are short of water, leading to water waste and uneven tobacco growth, and limiting the operating range. Therefore, a foliar sprinkler irrigation device for tobacco planting is proposed to solve the above problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a tobacco planting foliar irrigation device, which aims to improve the problem in the prior art that "the spacing between adjacent nozzles cannot be dynamically adjusted, resulting in poor flexibility of the irrigation device".

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1 and Figure 2This utility model provides an embodiment of a tobacco planting foliar irrigation device, including a housing 2. An electric flatbed cart 1 is installed at the bottom of the housing 2. The main components of the electric flatbed cart 1 include a frame, a motor, a battery, a control system, a transmission mechanism, and a walking mechanism. Commercially available mature products can be used. The electric flatbed cart 1 is powered by a battery and drives the entire electric flatbed cart 1 to move freely in the tobacco planting area, adapting to the irrigation needs of different plots, replacing manual handling, and improving work efficiency. A controller 9 is fixedly connected to the right side of the housing 2 to facilitate the control and parameter setting of the motor drive, the start and stop of the liquid pump 65, and the liquid supply mechanism 6 is installed inside the housing 2. A support frame 3 is fixedly connected to the top of the housing 2. A crossbar 4 is fixedly connected to the top of the support frame 3. Housings 5 ​​are fixedly connected to the left and right sides of the crossbar 4. An irrigation mechanism 7 is installed on the surface of the housing 5.

[0031] Reference Figures 2-4 The irrigation mechanism 7 includes a stepper motor 71 and a round rod 75. The stepper motor 71 is fixedly connected to the surface of the housing 5 away from the crossbar 4. The output shaft of the stepper motor 71 is fixedly connected to a screw 72. The stepper motor 71 drives the outermost moving block 74 to move horizontally through threaded transmission. The screw 72 is rotatably connected to the inner wall of the housing 5. The circumferential surface of the screw 72 is threadedly connected to a threaded sleeve 73. The round rod 75 is fixedly connected to the inner wall of the housing 5. The circumferential surface of the round rod 75 is slidably connected to the moving block 74. The round rod 75 provides a sliding track to improve the stability and accuracy of the moving block 74 during movement.

[0032] Reference Figures 2-4 Multiple movable blocks 74 are configured, and multiple movable blocks 74 are fixed to the nozzles 77 by connecting rods 76 to achieve multi-point irrigation. The inner wall of the movable block 74 furthest from the crossbar 4 is fixedly connected to the outer wall of the threaded sleeve 73. The remaining movable blocks 74 are not connected to the screw 72. The bottom of the movable block 74 is fixedly connected to the connecting rod 76, and the bottom of the connecting rod 76 is fixedly connected to the nozzle 77. The connecting rod 76 delivers the irrigation liquid from the hose 63 to the nozzle 77. The nozzle 77 adjusts its coverage area as the movable block 74 moves, so that multiple tobacco plants with different spacings can be irrigated at the same time, improving the efficiency of irrigation. A linkage mechanism 8 is set on the rear side of the movable block 74.

[0033] Reference Figure 1 and Figure 2The liquid supply mechanism 6 includes a water tank 61, which stores irrigation liquid and is replenished through a replenishment pipe 66. Waste liquid is discharged through a drain pipe 67. The water tank 61 is fixedly connected to the inner wall of the outer shell 2. A delivery pipe 62 is fixedly connected to the top of the water tank 61. The top of the delivery pipe 62 is fixedly connected to the bottom of the crossbar 4. The liquid supply mechanism 6 also includes a hose 63 and a fixing ring 64. One end of the hose 63 is fixedly connected to the surface of the connecting rod 76, and the other end of the hose 63 is fixedly connected to the surface of the delivery pipe 62. The delivery pipe 62 and the hose 63 form a liquid transmission channel. The hose 63 is fixed by the fixing ring 64 and can be bent within a certain range. The hose 63 is made of flexible material to adapt to changes in the position of the nozzle 77.

[0034] Reference Figure 1 and Figure 2 The fixing ring 64 is fixedly connected to the bottom of the housing 5. The hose 63 passes through the inside of the fixing ring 64. The surface of the infusion tube 62 is provided with a liquid pump 65 that pressurizes and delivers the liquid to the nozzle 77. The top of the water tank 61 is fixedly connected to the replenishment tube 66, and the right side of the water tank 61 is fixedly connected to the drain tube 67. The replenishment tube 66 replenishes the consumed liquid in real time, and the drain tube 67 cleans the residual liquid periodically.

[0035] Reference Figure 3 and Figure 4 The linkage mechanism 8 includes multiple connecting rods 81. The two ends of the multiple connecting rods 81 are respectively hinged to the close ends of adjacent connecting rods 81. The middle part of the connecting rods 81 is hinged to the rear middle part of the moving block 74. The multiple connecting rods 81 are hinged to form a transmission chain, which transmits the movement of the threaded sleeve 73 to other moving blocks 74, so as to realize the synchronous movement of the nozzles 77. The linkage mechanism 8 also includes connecting rods 82 and 83. One end of connecting rod 82 is hinged to the inner wall of the housing 5, and the other end of connecting rod 82 is hinged to the connecting rod 81 furthest from the crossbar 4. Through the rotation of the screw 72, the multiple moving blocks 74 are made to expand or contract at equal intervals through the linkage mechanism 8, thereby keeping the spacing of the nozzles 77 stable and improving the uniformity of irrigation.

[0036] Reference Figure 3 and Figure 4 One end of link 3 83 is hinged to the rear center of the moving block 74 closest to the crossbar 4, and the other end of link 3 83 is hinged to link 1 81 closest to the crossbar 4. The length of link 2 82 is equal to the length of link 3 83, and the length of link 2 82 is half that of link 1 81. The number of links 1 81 is one less than the number of moving blocks 74. The motion is transmitted through the hinges of link 1 81, link 2 82 and link 3 83 to ensure that all moving blocks 74 are displaced synchronously at equal intervals.

[0037] Working principle: In use, the device is moved to the tobacco planting area to be irrigated by the electric flatbed cart 1. The controller 9 starts the liquid pump 65 and the stepper motor 71. The stepper motor 71 starts, and its output shaft drives the screw 72 to rotate. The threaded sleeve 73 moves axially on the screw 72. The moving block 74 connected to the threaded sleeve 73 moves accordingly. Through the hinge transmission of multiple connecting rods 81 in the linkage mechanism 8, and the synergistic action of connecting rods 82 and 83, the other moving blocks 74 move synchronously and the spacing between the multiple moving blocks 74 is always equal. When the moving block 74 is displaced, the connecting rod 76 and the nozzle 77 move linearly along the axial direction of the screw 72. The hose 63 bends adaptively with the displacement of the moving block 74 to ensure continuous liquid supply.

[0038] The liquid pump 65 delivers the liquid in the water tank 61 to each nozzle 77 via the delivery pipe 62 and hose 63. The nozzles 77 spray the irrigation liquid evenly onto the tobacco leaves with stable pressure, achieving high-efficiency irrigation. After irrigating one area, the operator can move the electric flatbed cart 1 to the next area and repeat the above irrigation process. The whole process is highly automated, which can effectively improve irrigation efficiency, reduce water waste, and ensure that the tobacco plants receive uniform and sufficient water and nutrients.

[0039] During the irrigation process, the controller 9 can adjust the direction of the stepper motor 71 to achieve reciprocating scanning of the nozzle array 77, which can repeatedly irrigate the same tobacco plant, thereby improving the uniformity of irrigation. Alternatively, the stepper motor 71 can drive the screw 72 to rotate, so that the nozzles 77 can adjust their spacing with the displacement of the moving block 74. With the continuous forward movement of the electric flatbed trolley 1, multiple tobacco plants with different spacings can be irrigated simultaneously, improving irrigation efficiency, expanding the operating range, and efficiently completing the irrigation of tobacco leaves.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
