Description

Technical Field

[0001] This utility model relates to the field of agricultural planting technology, specifically to an irrigation device for cotton planting that can improve irrigation uniformity. Background Technology

[0002] Cotton, as an important economic crop, has phased water requirements during its growth. The seedling stage requires less water, while the budding and boll-opening stage requires significantly more water. Although traditional irrigation methods (such as furrow irrigation, sprinkler irrigation, and drip irrigation) are widely used, they are difficult to simultaneously supply water to both the canopy and the root system. The dense leaves above can block the stems, resulting in uneven distribution of irrigation water. Although existing adjustable sprinkler irrigation devices can adapt to changes in plant height, they still cannot solve the problem of water shortage in the stem area caused by leaf shading, resulting in water and fertilizer waste or localized drought, which restricts the improvement of cotton yield and quality. Therefore, there is an urgent need for an irrigation device for cotton cultivation that can improve irrigation uniformity. Utility Model Content

[0027] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. The preferred embodiments described are only examples. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0028] like Figures 1-4 As shown, the specific embodiment adopts the following technical solution: it includes a mobile cart 1 and a liquid storage tank 2, and the liquid storage tank 2 is fixedly installed on the upper part of the mobile cart 1;

[0029] It also includes:

[0030] Support column 3 is fixedly installed on the upper left side of the mobile cart 1. Motor 4 is fixedly installed inside the support column 3. Threaded rod 5 is fixedly installed on the output shaft of motor 4. Water pump 6 is fixedly installed on the upper part of the mobile cart 1. The water inlet pipe of water pump 6 is connected to liquid storage tank 2. Reinforcing ribs 15 are fixedly installed on all four sides of the support column 3 and are fixedly installed on the mobile cart 1. The reinforcing ribs 15 can improve the structural strength of the connection between the support column 3 and the mobile cart 1.

[0031] The lifting rod 8 is screwed onto the threaded rod 5 and is movably inserted into the support column 3. The mobile trolley 1 is equipped with a stem irrigation mechanism 9 that cooperates with the lifting rod 8. A connecting frame 10 is fixedly installed at the upper end of the lifting rod 8.

[0032] Two rotating rods 11 are respectively rotatably inserted through the front and rear sides of the connecting frame 10 via bearings. The front and rear sides of the connecting frame 10 are provided with flip rods 12, and the ends of the flip rods 12 are fixedly connected to the rotating rods 11. The connecting frame 10 is provided with a flipping and storage mechanism 13 connected to the rotating rods 11. The upper part of the mobile trolley 1 is fixedly provided with support wheels 16 at the front and rear sides of the support column 3. The support wheels 16 are movably abutting against one end of the flip rods 12. The support wheels 16 can provide auxiliary support for the flip rods 12 when flipped to the vertical state, so as to distribute the force at the connection between the rotating rods 11 and the flip rods 12.

[0033] No. 14, there are several No. 14 nozzles, which are respectively fixedly installed on the side walls of the two flip rods 12;

[0034] The stalk irrigation mechanism 9 includes:

[0035] Two sliders 9-1 are slidably installed in two slide grooves on the upper part of the mobile trolley 1. A vertical rod 9-2 is fixedly installed on the slider 9-1. Several nozzles 9-3 are fixedly installed on the side wall of the vertical rod 9-2. The nozzles 9-3 are connected to the outlet pipe of the water pump 6.

[0036] Two sliders 9-4 are slidably disposed in the two grooves opened on the opposite side walls of the two vertical rods 9-2. A connecting rod 9-5 is hinged to the slider 9-4. A driven rod 9-6 is fixedly disposed at one end of the connecting rod 9-5. One end of the driven rod 9-6 is rotatably inserted into the support column 3 through a bearing and fixedly sleeved with a gear 9-7.

[0037] Two racks 9-8 are fixedly installed in the two mounting slots 18 on the lifting rod 8. Each rack 9-8 meshes with a gear 9-7. When the lifting rod 8 moves upward, the engagement of racks 9-8 and gear 9-7 with the driven rod 9-6 causes the connecting rod 9-5 to flip, thereby moving the vertical rod 9-2 closer to the edge of the moving trolley 1, facilitating the connection of the second nozzle 9-3. Spraying water on the stems and roots of cotton plants reduces the obstruction of dense leaves above and improves irrigation uniformity. A spring 17 is fixedly installed in the first chute. One end of the spring 17 is fixedly connected to the first slider 9-1. After the first rack 9-8 is disengaged from the first gear 9-7, the rebound force applied by the spring 17 to the first slider 9-1 can prevent the first slider 9-1 from sliding randomly in the first chute and causing the vertical rod 9-2 and the second nozzle 9-3 to shift.

[0038] The flip-up storage mechanism 13 includes:

[0039] A bidirectional worm gear 13-1 is rotatably mounted in the connecting frame 10 via a bearing. A worm wheel 13-2 is fixedly sleeved on the rotating rod 11. The bidirectional worm gear 13-1 and the worm wheel 13-2 are meshed together.

[0040] The second gear 13-3 is fixedly sleeved on the bidirectional worm gear 13-1. The third gear 13-4, which meshes with the second gear 13-3, is rotatably arranged in the connecting frame 10 through a rotating shaft. The second rack 13-5, which meshes with the third gear 13-4, is fixedly arranged at the upper end of the support column 3. A strip groove 7 that cooperates with the second rack 13-5 is opened on the left side wall of the connecting frame 10 and the lifting rod 8.

[0041] Furthermore, reinforcing ribs 15 are fixedly installed on all four sides of the support column 3, and the reinforcing ribs 15 are fixedly installed on the mobile trolley 1. The flipping storage mechanism 13 can realize the synchronous flipping of the flipping rods 12 on both sides. When the device is idle, the flipping rods 12 can be flipped to a vertical state to reduce the space occupied in storage.

[0042] When using this invention, the mobile cart 1 is moved to the cotton field, and the motor 4 is started. The motor 4 drives the threaded rod 5 to rotate, causing the lifting rod 8 to move upward. The lifting rod 8 drives the connecting frame 10 and the first rack 9-8 to move upward. By utilizing the meshing of the first rack 9-8 and the first gear 9-7, the driven rod 9-6 drives the connecting rod 9-5 to rotate. The connecting rod 9-5 drives the second slider 9-4 to slide downward. By utilizing the sliding of the first slider 9-1 in the first groove, the vertical rod 9-2 can be moved towards the edge of the mobile cart 1, so that the second nozzle 9-3 can be as close as possible to the stem of the cotton plant. Furthermore, the upward movement of the connecting frame 10... During the process, the meshing of gear 13-4 and rack 13-5 causes gear 13-4 to rotate. Gear 13-4 drives the bidirectional worm gear 13-1 to rotate via gear 13-3. The bidirectional worm gear 13-1 drives the rotating rods 11 on both sides to rotate synchronously in opposite directions via worm wheel 13-2. This allows the flipping rods 12 on both sides to flip synchronously to an inclined position above the cotton plant. Then, the moving cart 1 can be pushed and the water pump 6 can be started, so that the first nozzle 14 can spray irrigation water on the leaves of the cotton plant and the second nozzle 9-3 can spray irrigation water on the stem of the cotton plant to achieve uniform irrigation of the cotton plant.

[0043] Compared with the prior art, the beneficial effects of this utility model are:

[0044] The lifting rod 8 drives the stem irrigation mechanism 9 and the flipping and storage mechanism 13 to work together, so that the first nozzle 14 covers the plant leaves and the second nozzle 9-3 accurately sprays water onto the stem and root parts, effectively solving the problem of water shortage in the stem area caused by leaf shading in traditional irrigation, and significantly improving the uniformity of irrigation.

[0045] The motor 4 can drive the threaded rod 5 to adjust the height of the lifting rod 8, ensuring that the No. 1 sprinkler 14 can adapt to different canopy heights and meet the irrigation needs of cotton throughout its entire growth period.

[0046] The flipping storage mechanism 13 can realize the synchronous extension and retraction of the flipping rods 12 on both sides through the meshing of the bidirectional worm gear 13-1 and the worm wheel 13-2. When not in use, it can be stored vertically to reduce the footprint.

[0047] The support wheel 16 can provide auxiliary support for the flipping rod 12 when it is flipped to the vertical position, so as to distribute the force at the connection between the rotating rod 11 and the flipping rod 12.

[0048] For those skilled in the art, modifications can be made to the technical solutions described in the foregoing embodiments, and equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
