Description

Technical Field

[0001] This utility model relates to the field of agricultural technology, specifically to a high-efficiency pesticide spraying device for crops. Background Technology

[0002] Crops are plants cultivated by humans for specific purposes and are usually distinguished from wild plants. As the foundation of agricultural production, crops play a central role in the development of human civilization, food security, and economic development. Crops are plants that have undergone long-term artificial selection and domestication and have three basic characteristics: economic value and ornamental value.

[0003] Chinese utility model patent CN207767369U, published on August 28, 2018, discloses a pesticide spraying vehicle, including a transport vehicle equipped with a spraying device. The spraying device includes a pesticide tank, a pesticide pump, a reel, and a spraying hose. An inlet pipe connects the inlet of the pesticide pump to the pesticide tank, and an outlet pipe connects the outlet of the pesticide pump. The spraying hose is wound around the reel, with its inlet end connected to the outlet pipe, and its outlet end extending out of the reel's housing. The pesticide tank, carried by the transport vehicle, can hold a large amount of pesticide, covering a large spraying area, eliminating the need for frequent refills and improving spraying efficiency. It also eliminates the need for workers to carry pesticides, significantly reducing their workload. Furthermore, the reel allows for easy adjustment of the spraying hose length, enabling large-area pesticide spraying with a single stop, reducing the need for frequent vehicle restarts and further enhancing spraying efficiency.

[0004] However, the above-mentioned publicly disclosed solutions have the following shortcomings: the existing spraying devices are vehicle-mounted spraying devices, which cannot enter the furrows of crops or reach deep into the crops for spraying, and have large requirements for the spacing between crops, thus making them suitable for a narrow range of crops. Utility Model Content

[0005] The purpose of this invention is to address the technical problem that existing pesticide spraying devices are vehicle-mounted, which cannot reach the furrows or deep into the crops for spraying, and require large spacing between crops, thus making them unsuitable for narrow crop areas. This invention provides a highly efficient pesticide spraying device for crops.

[0006] To achieve the above objectives, the present invention adopts the following technical solution;

[0007] This utility model discloses a high-efficiency pesticide spraying device for crops, comprising a suspended rope fixed in a crop furrow; fixing devices at both ends of the suspended rope; a rope clamp plate sleeved on the suspended rope; a drive wheel rotatably connected inside the rope clamp plate; a motor fixedly connected to the drive wheel; a pressing wheel rotatably connected to the rope clamp plate corresponding to the drive wheel; a hanging rod sleeved at both ends of the pressing wheel; a hanging box fixedly connected to the lower end of the hanging rod; a battery and an electric spraying box fixedly connected inside the hanging box; multiple output pipes connected and fixedly connected to the electric spraying box; a three-way valve connected and fixedly connected to the end of each output pipe; multiple gooseneck tubes connected and fixedly connected to the three-way valve; an atomizing nozzle fixedly connected to the end of each gooseneck tube; an adjusting frame fixedly connected to the three-way valve; the adjusting frame slidably sleeved on the hanging rod; and a fastener threadedly connected to the adjusting frame.

[0008] Furthermore, the fixing device includes a support member inserted into the soil; the support member is rotatably connected to a guide wheel corresponding to the slot of the suspended rope.

[0009] Furthermore, the support member is slidably sleeved with an adjusting ring; the adjusting ring has a hole with a threaded connection to a bolt; a pressing plate is sleeved on the bolt; and the adjusting ring is sleeved on the suspension rope.

[0010] The present invention provides a high-efficiency pesticide spraying device for crops, which has the following beneficial effects:

[0011] 1. This utility model uses an electric spraying box filled with the pesticide solution to be sprayed. Then, the tension of the suspension rope is adjusted by a fixing device to adapt to crops of different heights. The height and shape of multiple gooseneck tubes are then adjusted so that the atomizing nozzles can be aligned with the upper and lower surfaces of the crop leaves. Driven by a motor, the drive wheel moves on the suspension rope, thereby driving the electric spraying box to move back and forth. The pesticide solution is sprayed from the atomizing nozzles for efficient spraying of crops. The fixing structure is simple. When needed, the suspension rope is installed between two fixing devices. When not needed, the suspension rope is removed without affecting harvesting and other operations.

[0012] 2. This utility model uses a guide wheel to reduce friction when the suspended rope moves, and it can move quickly and easily. By inserting the support into both ends of the ditch in the crop field for fixation, the suspended rope is positioned above the ditch and between the crops. This allows the moving path of the electric sprayer to coincide with the gap between the crops, enabling rapid spraying by utilizing the gap between the crops. Attached Figure Description

[0021] Please see Figure 1-3As shown, a high-efficiency pesticide spraying device for crops includes a suspended rope 1 fixed in a crop furrow; fixed devices are provided at both ends of the suspended rope 1; a rope clamp 2 is sleeved on the suspended rope 1; a drive wheel 4 is rotatably connected inside the rope clamp 2; a motor 5 is fixedly connected to the drive wheel 4; a pressing wheel 7 is rotatably connected to the rope clamp 2 corresponding to the drive wheel 4; a hanging rod 8 is sleeved on both ends of the pressing wheel 7; a hanging box 9 is fixedly connected to the lower end of the hanging rod 8; a storage battery 11 and an electric spraying box 10 are fixedly connected inside the hanging box 9; multiple output pipes 12 are connected and fixedly connected to the electric spraying box 10; a three-way valve 13 is connected and fixedly connected to the end of the output pipe 12; multiple gooseneck tubes 14 are connected and fixedly connected to the three-way valve 13; an atomizing nozzle 15 is fixedly connected to the end of the gooseneck tube 14; and an adjustment device is fixedly connected to the three-way valve 13. The section frame 16 is slidably fitted onto the hanging rod 8. The adjusting frame 16 has a threaded connection to a fastener 17. The electric spraying box 10 is filled with the pesticide to be sprayed, and then the tension of the suspension rope 1 is adjusted by the fixing device to adapt to crops of different heights. Then, the height and shape of multiple gooseneck tubes 14 are adjusted so that the atomizing nozzles 15 can be aligned with the upper and lower surfaces of the crop leaves. Then, driven by the motor 5, the drive wheel 4 moves on the suspension rope 1, thereby driving the electric spraying box 10 to move back and forth. The pesticide is sprayed out from the atomizing nozzles 15 for efficient spraying of the crops. The fixing structure is simple. When needed, the suspension rope 1 is installed between the two fixing devices. When not needed, the suspension rope 1 is removed without affecting harvesting and other operations.

[0022] The fixing device includes a support member 19 inserted into the soil; the support member 19 is rotatably connected to a guide wheel 24 corresponding to the suspended rope 1 through a slot. The guide wheel 24 reduces friction when the suspended rope 1 moves, and makes it convenient and fast to move. The support member 19 is inserted into both ends of the ditch in the crop field for fixing, so that the suspended rope 1 is above the ditch and between the crops, so that the moving path of the electric sprayer box 10 coincides with the gap between the crops, and the gap between the crops can be used for fast spraying.

[0023] The support member 19 is slidably sleeved with an adjusting ring 20; the adjusting ring 20 has a hole with a threaded connection to a bolt 22; a pressing plate 21 is sleeved on the bolt 22; the adjusting ring 20 is sleeved on the suspended rope 1, and by rotating the bolt 22 in both directions, the pressing plate 21 is pushed to press the suspended rope 1 onto the adjusting ring 20, thereby fixing and adjusting the length of the suspended rope 1.

[0024] A counterweight ring 23 is fitted onto the support member 19; the counterweight ring 23 has multiple through holes, through which metal tubes are inserted and fixed to the ground, making the fixed connection more stable; by the counterweight ring 23 adhering to the ground, the support member 19 is kept vertically fixed in the soil, stably supporting the suspended rope 1 above the ditch.

[0025] Two balance wheels 6 are rotatably connected to the two sides of the drive wheel 4 inside the rope slot 3. The balance wheels 6 increase the contact area with the suspended rope 1, which limits the left and right swaying of the hoisting box 9 during transportation, thus ensuring stability and safety even when moving at high speed during spraying.

[0026] The rope clamp plate 2 has a rope clamping groove 3 corresponding to the suspended rope 1; the hanging box 9 has a through groove 18 corresponding to the output pipe 12. The through groove 18 allows the position of the output pipe 12 to be maintained between the two hanging rods 8, thereby protecting it and preventing it from being obstructed by protruding crops when moving between crops for spraying. The rope clamping groove 3 is fitted onto the suspended rope 1, ensuring that the rope clamp plate 2 remains stable and safe during use.
