Description

Technical Field

[0001] This utility model relates to the field of flue-cured tobacco planting, and in particular to a uniform drip irrigation device for flue-cured tobacco planting. Background Technology

[0002] Flue-cured tobacco is a crop with relatively strict requirements for water and nutrient supply. During the growth process of flue-cured tobacco, different water and nutrient conditions are required at different stages. For example, after transplanting, the soil needs to be kept moist to promote root growth; during the vigorous growth period, the demand for water and nutrients increases, and an adequate supply is needed to ensure the growth and development of leaves; while during the maturity period, water should be appropriately controlled to improve the quality of tobacco leaves. Drip irrigation, as an advanced irrigation technology, has the advantages of water saving, energy saving, and labor saving. It can directly deliver water and nutrients to the roots of crops, improving the utilization rate of water and nutrients.

[0003] During drip irrigation in flue-cured tobacco cultivation, impurities in the water and dust in the air can easily cause blockages at the drip head outlets. Once the drip head is blocked, drip irrigation will be interrupted or uneven, making it impossible to provide a stable water supply to the flue-cured tobacco.

[0004] In response to the technical problem that drip heads are prone to clogging, causing drip irrigation interruptions or unevenness, this application proposes a uniform drip irrigation device for flue-cured tobacco planting. Utility Model Content

[0005] The purpose of this invention is to solve the problem of drip head clogging, which can cause drip irrigation interruptions or unevenness. It proposes a uniform drip irrigation device for flue-cured tobacco cultivation. The device rotates a lead screw, which moves the unblocking rod on the outer wall downwards to clear the inside of the drip head, preventing dust or impurities from clogging the drip head outlet. This avoids drip irrigation interruptions or unevenness caused by clogging, ensuring a stable water supply during flue-cured tobacco cultivation. It also ensures uniform mixing of fertilizer and water, preventing fertilizer sedimentation due to uneven mixing and thus improving fertilizer utilization.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a uniform drip irrigation device for flue-cured tobacco planting, comprising a water storage tank and a support frame. A support rod is fixedly connected to the top of the water storage tank, and a rotating shaft is rotatably connected to the inner wall of the support rod. The rotating shaft is connected to a stirring blade via a gear assembly. A connecting pipe is fixedly connected to the front end of the water storage tank, and a drip pipe is fixedly connected to the front end of the connecting pipe. The outer wall of the drip pipe is fixedly connected to the inner wall of the support frame, and multiple drip heads are fixedly connected to the bottom end of the drip pipe. A connecting shaft is rotatably connected to the inner wall of the support frame, and multiple first bevel gears are fixedly connected to the outer wall of the connecting shaft. The first bevel gears are connected to a dredging rod via a dredging assembly.

[0007] Furthermore, the gear assembly includes a connecting rod fixedly connected to the outer wall of the rotating shaft, and rotating shafts are rotatably connected to the inner walls of both the left and right sides of the connecting rod. One end of the inner side of the stirring blade is fixedly connected to the outer wall of the rotating shaft.

[0008] Furthermore, a drive gear is fixedly connected to the top of the rotating shaft, and an internal gear ring is meshed with the outer wall of the drive gear. The outer wall of the internal gear ring is fixedly connected to the inner wall of the water storage tank.

[0009] Furthermore, a first motor is fixedly connected to the top of the support rod, and the top of the rotating shaft is fixedly connected to the drive end of the first motor.

[0010] Furthermore, the unblocking assembly includes a second bevel gear meshing with the outer wall of the first bevel gear, a lead screw fixedly connected to the bottom end of the second bevel gear, and the inner wall of the unblocking rod threadedly connected to the outer wall of the lead screw.

[0011] Furthermore, the inner wall of the drip head is fixedly connected to a fixing rod, the outer wall of the screw is rotatably connected to the inner wall of the fixing rod, and the outer wall of the unblocking rod is slidably connected to the inner wall of the fixing rod.

[0012] Furthermore, a second motor is fixedly connected to the right end of the support frame, and the right end of the connecting shaft is fixedly connected to the drive end of the second motor.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, the connecting shaft is driven to rotate by the second motor, which in turn rotates the screw inside the drip head. The screw moves the unblocking rod on the outer wall downward to unblock the inside of the drip head, preventing dust or impurities from clogging the drip head outlet. This avoids drip irrigation interruption or unevenness caused by blockage, ensuring a stable water supply during the tobacco planting process, and thus guaranteeing the water requirements for tobacco growth.

[0015] 2. In this utility model, fertilizers and other materials are added to a water storage tank, and the stirring blades on both sides are driven by the first motor to stir the water storage tank, so that the fertilizers and water are evenly mixed.

[0024] 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.

[0025] Reference Figures 1-3 This utility model provides an embodiment of a uniform drip irrigation device for flue-cured tobacco cultivation, comprising a water storage tank 1 and a support frame 12. A support rod 2 is fixedly connected to the top of the water storage tank 1. A rotating shaft 4 is rotatably connected to the inner wall of the support rod 2. A connecting rod 5 is fixedly connected to the outer wall of the rotating shaft 4. Rotating shafts 6 are rotatably connected to the inner walls of both sides of the connecting rod 5. One end of a stirring blade 7 is fixedly connected to the outer wall of the rotating shaft 6. A drive gear 8 is fixedly connected to the top of the rotating shaft 6. An internal gear ring 9 is meshed with the outer wall of the drive gear 8. The outer wall of the internal gear ring 9 is fixedly connected to the inner wall of the water storage tank 1. A first motor 3 is fixedly connected to the top of the support rod 2. The top of the rotating shaft 4 is fixedly connected to the drive end of the first motor 3. A connecting pipe 10 is fixedly connected to the front end of the water storage tank 1. A drip pipe 11 is fixedly connected to the front end of the connecting pipe 10.

[0026] Specifically, the bottom end of the rotating shaft 6 does not contact the bottom end of the inner wall of the water storage tank 1. The water storage tank 1 needs to be installed at a higher position, which is higher than the position of the drip pipe 11. The water in the water storage tank 1 will automatically flow from the higher position to the lower position due to gravity, and then flow into the drip pipe 11. A control valve is installed on the connecting pipe 10. The control valve can control whether the water flow inside the connecting pipe 10 is smooth.

[0027] Reference Figures 4-6 The outer wall of the drip pipe 11 is fixedly connected to the inner wall of the support frame 12. Multiple drip heads 13 are fixedly connected to the bottom end of the drip pipe 11. A connecting shaft 15 is rotatably connected to the inner wall of the support frame 12. Multiple first bevel gears 17 are fixedly connected to the outer wall of the connecting shaft 15. Second bevel gears 18 are meshed with the outer wall of the first bevel gears 17. A lead screw 19 is fixedly connected to the bottom end of the second bevel gear 18. The inner wall of the unblocking rod 20 is threadedly connected to the outer wall of the lead screw 19. A fixing rod 16 is fixedly connected to the inner wall of the drip head 13. The outer wall of the lead screw 19 is rotatably connected to the inner wall of the fixing rod 16. The outer wall of the unblocking rod 20 is slidably connected to the inner wall of the fixing rod 16. A second motor 14 is fixedly connected to the right end of the support frame 12. The right end of the connecting shaft 15 is fixedly connected to the drive end of the second motor 14.

[0028] Specifically, the support frame 12 is installed on the ground and supports the drip pipe 11. The drip head 13 is supported by two rods inside the fixed rod 16. The mixture of fertilizer and water flows around the fixed rod 16 and exits from the outlet at the bottom of the drip head 13 for drip irrigation of tobacco. The outlet of the drip head 13 is relatively small, so it is easily blocked by impurities in the water or dust in the air. The second motor 14 drives the lead screw 19 to rotate, so that the unblocking rod 20 unblocks the outlet. The second motor 14 can rotate in the opposite direction. When the unblocking rod 20 reaches the bottom, the second motor 14 rotates in the opposite direction to retract the unblocking rod 20.

[0029] Working principle: During use, fertilizer is added to the water storage tank 1 from the top. Then, the first motor 3 on the support rod 2 is started, driving the rotating shaft 4 to rotate. The rotating shaft 4 then drives the connecting rod 5 to rotate, which in turn drives the rotating shafts 6 on both sides to rotate. This, in turn, drives the drive gear 8 at the top of the rotating shaft 6 to rotate. As the drive gear 8 rotates with the connecting rod 5, it rotates on its own inside the inner toothed ring 9, causing the rotating shaft 6 to rotate simultaneously with the connecting rod 5. This causes the stirring blades 7 to rotate around the inner wall of the water storage tank 1 while simultaneously rotating on their own, thoroughly mixing the fertilizer inside the water storage tank 1. Then, the control valve on the connecting pipe 10 is opened, allowing the water storage tank 1 to... The mixture of fertilizer and water enters the drip pipe 11 through the connecting pipe 10, and finally drips the tobacco through the drip head 13 at the bottom of the drip pipe 11. When the drip head 13 is used for a long time, impurities in the water or dust in the air will accumulate at the outlet of the drip head 13, causing the drip head 13 to be blocked and unable to drip. At this time, the second motor 14 is started. The second motor 14 drives the connecting shaft 15 to rotate, which in turn drives the first bevel gear 17 to rotate. The first bevel gear 17 drives the second bevel gear 18 to rotate, and the second bevel gear 18 drives the lead screw 19 to rotate, causing the unblocking rod 20 on the outer wall of the lead screw 19 to move downward and unblock the inside of the drip head 13.

[0030] 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.
