Description

Technical Field

[0001] This utility model relates to the field of inter-row spraying technology for wheat, and in particular to a contour-following foliar fertilizer spraying device for inter-row spraying of wheat. Background Technology

[0002] Wheat is an important food crop in my country. During its growth cycle, it requires the reasonable supplementation of nitrogen, phosphorus, potassium and trace elements to ensure high yield and quality. Foliar fertilizer spraying between rows can directly transport nutrients to the leaves, improve absorption efficiency, promote photosynthesis and nutrient accumulation, and facilitate targeted fertilization between dense rows of wheat. During the spraying process, the device needs to be able to move stably between rows and evenly atomize and spray the fertilizer solution onto the plant leaves to achieve precise nutrient supplementation for the crop. Therefore, the design and application of foliar fertilizer spraying devices for inter-row spraying of wheat can be proposed.

[0003] Most existing foliar fertilizer spraying devices are backpack-style structures, relying mainly on manual carrying on shoulders and hand-held sprayers for operation. When used in fields with narrow row spacing and dense plant growth, such as wheat, it is inconvenient to move between rows, resulting in high labor intensity and difficulty in achieving uniform spray coverage. Although some spraying devices with push-type functions can move in farmland, the nozzle angle is usually fixed, making it impossible to flexibly adjust the spraying direction according to the height of wheat plants and the distribution between rows. This can easily lead to spray dead spots or concentrated fertilizer spraying, affecting fertilizer absorption and utilization efficiency, and limiting the adaptability and uniformity of fertilization in different field environments.

[0004] Therefore, this utility model proposes a contour-following foliar fertilizer spraying device for inter-row application of wheat. Utility Model Content

[0005] Therefore, in order to overcome the problems that most existing foliar fertilizer spraying devices are backpack-type structures, which require manual shoulder and hand operation, making it inconvenient to move through fields with narrow row spacing and dense plants such as wheat, resulting in high labor intensity and uneven spraying, and that some pushable devices, although movable, have fixed nozzle angles that cannot be flexibly adjusted according to plant height and row spacing, easily leading to spray dead spots or fertilizer concentration, affecting fertilizer absorption and utilization, and having poor adaptability.

[0006] The technical solution of this utility model is as follows: a contoured foliar fertilizer spraying device for inter-row spraying of wheat, comprising a base, an output pipe and a rotating ring; a fertilizer tank is fixedly connected to the top of the base, a wheel is fixedly connected to the bottom of the base, the output pipe is fixedly connected to the inside of the fertilizer tank, a support rod is fixedly connected to the top of the base, the rotating ring is rotatably connected to the end of the support rod away from the base, a connecting rod is fixedly connected to the inner side wall of the rotating ring, and the connecting rod is symmetrically installed at both ends of the rotating ring.

[0007] Preferably, the output pipe is located near the support rod, and the support rod is located away from the fertilizer tank.

[0008] Preferably, a push handle is fixedly connected to the back of the base, an anti-slip ring is fixedly connected to the outer side wall of the push handle, the anti-slip ring is located away from the base, a support frame is fixedly connected to the top of the base, and the output tube is fixedly connected to the inner side wall of the support frame.

[0009] Preferably, a control valve is fixedly connected inside the output pipe, and a connecting pipe is fixedly connected to the end of the output pipe away from the control valve. The connecting pipes are symmetrically installed on the front of the output pipe, and a nozzle is fixedly connected to the end of the connecting pipe away from the output pipe.

[0010] Preferably, a rotating rod is engaged with the inside of the rotating ring, and a handle is fixedly connected to the end of the rotating rod away from the rotating ring. A sliding disc is slidably connected to the inner side wall of the rotating ring, and the sliding disc is fixedly connected to the end of the rotating rod away from the handle.

[0011] Preferably, a return spring is fixedly connected to the side of the sliding disk near the rotating rod. The return springs are symmetrically installed near the outer wall of the sliding disk. The end of the return spring away from the sliding disk is fixedly connected to the inside of the rotating ring. A limit rod is fixedly connected to the side of the sliding disk away from the rotating rod. The limit rod is symmetrically installed near the outer wall of the sliding disk. A limit gear is fixedly connected to the end of the support rod near the rotating ring. The limit rod meshes with the outer wall of the limit gear.

[0012] Preferably, a connecting ring is fixedly connected to the end of the connecting rod away from the rotating ring, and a guide rod is slidably connected inside the connecting ring. The guide rods are symmetrically and equidistantly installed inside the connecting rod. A clamping ring is fixedly connected to the end of the guide rod away from the connecting ring. The clamping rings are symmetrically arranged near the inner wall of the connecting ring. A soft pad is fixedly connected to the inner wall of the clamping ring.

One end of the fastening spring is fixedly connected to the inner wall of the connecting ring, and the other end of the fastening spring is fixedly connected to the outer wall of the clamping ring.

[0013] The beneficial effects of this utility model are: 1.

At this time, rotate the rotating rod, and the rotating ring will rotate synchronously. It will also drive the nozzle to adjust the lateral angle through the connecting rod, so that the nozzle can point to different spraying directions. Finally, release the handle, and the return spring will push the sliding plate downward. The limiting rod will re-engage with the limiting toothed plate to limit the rotating ring and prevent accidental deflection, thereby completing the spraying direction adjustment of the device. 2. When the device starts spraying fertilizer, open the control valve to allow the fertilizer in the fertilizer tank to enter the nozzle. The nozzle atomizes the fertilizer and sprays it onto the wheat leaves. During this process, push the handle to drive the wheels to rotate continuously, so that the base moves along the wheat rows to achieve uniform spraying of the target area. 3. During the spraying process of the device, the fastening spring pushes the clamping ring to continuously clamp the nozzle, preventing the nozzle from slipping out of the connecting ring, ensuring that the nozzle is securely fixed, thereby achieving stable fertilization operation of the device.

The output pipe 4 is fixedly connected to the inner wall of the support frame 103. The anti-slip ring 102 can prevent the hand from slipping and improve the safety of operation. The support frame 103 provides stable support for the output pipe 4 during spraying operations, preventing shaking or displacement.

[0023] A control valve 401 is fixedly connected inside the output pipe 4. A connecting pipe 402 is fixedly connected to the end of the output pipe 4 away from the control valve 401. The connecting pipes 402 are symmetrically installed on the front of the output pipe 4. A nozzle 403 is fixedly connected to the end of the connecting pipe 402 away from the output pipe 4.

[0024] A rotating rod 601 is engaged with the inside of the rotating ring 6. A handle 602 is fixedly connected to the end of the rotating rod 601 away from the rotating ring 6. A sliding disk 603 is slidably connected to the inner side wall of the rotating ring 6. The sliding disk 603 is fixedly connected to the end of the rotating rod 601 away from the handle 602. The handle 602 facilitates manual control of the rotation of the rotating rod 601, improving the convenience of operation.

[0025] A return spring 604 is fixedly connected to the side of the sliding disc 603 near the rotating rod 601. The return springs 604 are symmetrically installed near the outer wall of the sliding disc 603. The end of the return spring 604 away from the sliding disc 603 is fixedly connected to the inside of the rotating ring 6. A limit rod 605 is fixedly connected to the side of the sliding disc 603 away from the rotating rod 601. The limit rods 605 are symmetrically installed near the outer wall of the sliding disc 603. A limit toothed disc 606 is fixedly connected to the end of the support rod 5 near the rotating ring 6. The limit rod 605 meshes with the outer wall of the limit toothed disc 606. The limit rod 605 and the limit toothed disc 606 can be securely locked after the angle of the nozzle 403 is adjusted, preventing the angle from shifting due to vibration during spraying, thereby ensuring that the nozzle 403 is reliably positioned and the spraying direction is accurate.

[0026] A connecting ring 701 is fixedly connected to the end of the connecting rod 7 away from the rotating ring 6. A guide rod 702 is slidably connected inside the connecting ring 701. The guide rods 702 are symmetrically and equidistantly installed inside the connecting rod 7. A clamping ring 703 is fixedly connected to the end of the guide rod 702 away from the connecting ring 701. The clamping rings 703 are symmetrically arranged near the inner wall of the connecting ring 701. A soft pad 704 is fixedly connected to the inner wall of the clamping ring 703. The nozzle 403 is in close contact with the inner wall of the soft pad 704. The outer side of the guide rod 702... A fastening spring 705 is provided, with one end of the fastening spring 705 fixedly connected to the inner wall of the connecting ring 701 and the other end of the fastening spring 705 fixedly connected to the outer wall of the clamping ring 703. Under the elastic force of the fastening spring 705, the clamping ring 703 always forms a continuous clamping force on the nozzle 403 to prevent the nozzle 403 from loosening or falling off during spraying. The guide rod 702 limits and guides the movement direction of the clamping ring 703 to ensure that the clamping force is uniformly transmitted along the axial direction and to avoid deviation that causes the nozzle 403 to shake.

[0027] Working principle: See Figures 1-4 As shown, when the device is ready to be used, first, add the fertilizer to be sprayed into the fertilizer tank 2. Then, hold the anti-slip ring 102 and apply external force to push the push handle 101 to make the wheel 3 rotate, thereby moving the base 1 to the work area and completing the preparation of the device. See Figures 5-7 As shown, when the device is ready to spray fertilizer, first, hold the handle 602 and apply external force to pull the rotating rod 601 upward, so that the sliding plate 603 overcomes the elastic force of the return spring 604 and moves upward along the inner wall of the rotating ring 6. The sliding plate 603 drives the limiting rod 605 to move away from the limiting toothed plate 606, releasing the engagement of the two. At this time, continue to hold the handle 602 and apply external force to rotate the rotating rod 601. Since the rotating ring 6 and the rotating rod 601 are engaged with each other, the rotating ring 6 rotates synchronously at the top of the support rod 5, and drives the nozzle 403 to make lateral angle adjustment through the connecting rod 7, so that the nozzle 403 can point to different spraying directions. Finally, release the handle 602. Under the elastic force of the return spring 604, push the sliding plate 603 downward, and the limiting rod 605 re-engages with the limiting toothed plate 606 to limit the rotating ring 6 and prevent it from deflecting accidentally, thereby completing the spraying direction adjustment of the device. See Figures 3-5 As shown, when the device starts spraying fertilizer, first, hold and apply external force to open the control valve 401, so that the fertilizer in the fertilizer tank 2 flows out through the output pipe 4 and enters the nozzle 403 through the connecting pipe 402. Then, the nozzle 403 atomizes the fertilizer and sprays it onto the wheat leaves. During this process, hold the anti-slip ring 102 and apply external force to push the push handle 101, which drives the wheel 3 to rotate continuously, so that the base 1 moves along the wheat rows to achieve uniform spraying of the target area. See Figures 4-7 As shown, during the spraying process of the device, the support frame 103 provides stable support for the output pipe 4. Under the elastic force of the fastening spring 705, the clamping ring 703 is pushed to continuously clamp the nozzle 403 through the soft pad 704, preventing the nozzle 403 from slipping out of the connecting ring 701. The guide rod 702 limits and guides the clamping ring 703 and the fastening spring 705 to prevent them from deviating, ensuring that the nozzle 403 is fixed reliably, thereby realizing the stable fertilization operation of the device.
