Description

Technical Field

[0001] This invention relates to the field of weeding equipment technology, specifically to a weeding device for cultivating fruit tree seedlings. Background Technology

[0002] Fruit trees refer to trees that bear edible fruit, and are a general term for perennial plants that provide edible fruits and seeds. Fruit tree seedlings include pear, apricot, peach, and apple seedlings. Weeding is necessary during the seedling growth period when cultivating fruit tree seedlings. To save labor, herbicides are usually sprayed onto the weeds. In existing technologies, automated spraying equipment is often used to ensure efficiency. However, this method suffers from problems such as difficulty in controlling the spraying area and the risk of the atomized herbicide drifting onto the seedlings and causing damage. Existing technologies have not adequately addressed these issues, hindering normal operations in this field. Therefore, there is an urgent need for a weeding device for fruit tree seedling cultivation to solve these problems. Summary of the Invention

[0003] This invention proposes a weeding device for fruit tree seedling cultivation, which solves the problem in related technologies that the sprayed herbicides can easily come into contact with the seedlings.

[0004] The technical solution of the present invention is as follows: A weeding device for cultivating fruit tree seedlings includes a frame, a mounting frame, a nozzle, a rotating shaft, and a seedling-covering belt. The mounting frame is mounted on the frame, and the nozzle is mounted on the mounting frame for spraying herbicides. Two rotating shafts are rotatably mounted on the mounting frame and rotate synchronously in the same direction. The two ends of the seedling-covering belt are respectively mounted on the two rotating shafts. After the rotating shafts rotate, the seedling-covering belt is used to wrap around the seedlings from one rotating shaft to the other. The seedling-covering belt is located above the seedlings and is used to cover the seedlings.

[0005] Optionally, it also includes a seedling-shading curtain, which is hinged to the edge of the seedling-shading strip. There are multiple seedling-shading curtains, which are evenly distributed along the length of the seedling-shading strip. The seedling-shading strip has the seedling-shading curtain on both sides. The seedling-shading curtain hangs down by its own weight to block the sides of the seedlings. A seedling-shading space is formed between the seedling-shading strip and the seedling-shading curtain, which is used to accommodate the seedlings.

[0006] Optionally, it also includes a drive wheel, which is rotatably mounted on the mounting bracket and drivenly connected to the rotating shaft. The drive wheel is used to contact the ground and roll on the ground.

[0007] Optionally, it also includes a lifting frame, which is slidably mounted on the frame and the mounting frame is rotatably mounted on the lifting frame.

[0008] Optionally, it also includes a support frame and a support shaft. The support frame is slidably disposed relative to the mounting frame, and the support shaft is rotatably disposed on the support frame. The support frame and the support shaft are both arranged in pairs, and the support shaft is used to support the seedling shielding strip.

[0009] Optionally, it also includes a guide post and a telescopic cylinder, wherein the guide post is slidably mounted on the mounting frame, the support frame is mounted on the guide post, the telescopic cylinder is mounted on the mounting frame, and the telescopic end of the telescopic cylinder acts on the support frame.

[0010] Optionally, it also includes a medicine storage box and a connecting hose. The medicine storage box is mounted on the mounting frame. One end of the connecting hose is connected to the medicine storage box, and the other end is used to connect to the spray head. There are multiple spray heads, which are located on both sides of the seedling shade strip.

[0011] Optionally, it also includes a spray pipe, which is rotatably mounted on the mounting bracket, with the nozzle mounted on the spray pipe and the connecting hose connected to the spray pipe.

[0012] Optionally, a connecting frame is also included, which is mounted on the frame and has connecting holes for connecting to the walking unit.

[0013] Optionally, it also includes traveling wheels, which are rotatably mounted on the frame. There are four traveling wheels, located at the four corners of the frame.

[0014] The working principle and beneficial effects of this invention are as follows:

[0015] To prevent herbicide from falling onto seedlings during spraying, a shaded area is added to shield them from the herbicide. The shaded area is connected to two rotating shafts at both ends, which rotate synchronously and in the same direction. As the shafts rotate, the shaded area is wound from one shaft to the other. The nozzles are atomizing nozzles positioned above the shaded area. The rotation of the shafts is synchronized with the movement of the equipment. As the equipment moves forward, the nozzles spray herbicide downwards. The rotation of the shaft in front of the nozzles automatically lays out the shaded area above the seedlings, while the rotation of the shaft behind the nozzles automatically retracts the shaded area. This ensures that the seedlings within the spray area are protected by the shaded area, significantly reducing the amount of herbicide adhering to the seedlings.

[0016] The seedling shade strip is designed to move in real time to ensure that the nozzles and the shade strip are always in relative motion. This is because if the shade strip is stationary, the nozzles will continuously spray herbicide mist onto a fixed area of ​​the shade strip. The herbicide, initially atomized, will gradually accumulate in this area and drip downwards as it is obstructed. Since the seedlings are below the shade strip, it is easily exposed to the herbicide. However, by designing the shade strip to move in real time, this herbicide accumulation is completely prevented, avoiding the problem of herbicide dripping. Attached Figure Description

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0026] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0027] Reference Figures 1-4 The first embodiment of the present invention provides a weeding device for fruit tree seedling cultivation, comprising a frame 1, a mounting frame 2, a nozzle 3, a rotating shaft 4, and a seedling-covering belt 5. The mounting frame 2 is mounted on the frame 1, and the nozzle 3 is mounted on the mounting frame 2 for spraying herbicides. Two rotating shafts 4 are rotatably mounted on the mounting frame 2, and the two rotating shafts 4 rotate synchronously in the same direction. The two ends of the seedling-covering belt 5 are respectively mounted on the two rotating shafts 4. After the rotating shafts 4 rotate, the seedling-covering belt 5 is used to wrap around the seedling from one rotating shaft 4 to the other rotating shaft 4. The seedling-covering belt 5 is located above the seedling and is used to cover the seedling.

[0028] In this embodiment, to prevent herbicide from falling onto seedlings during spraying, a seedling-shielding strip 5 is added to block the herbicide. The two ends of the seedling-shielding strip 5 are connected to two rotating shafts 4, which rotate synchronously and in the same direction. As the two shafts 4 rotate, the seedling-shielding strip 5 can be wrapped from one shaft 4 to the other. The nozzle 3 is an atomizing nozzle, positioned above the seedling-shielding strip 5. The rotation of the rotating shafts 4 is synchronized with the movement of the equipment. As the equipment moves, the nozzles 3 spray herbicide downwards. The rotation of the rotating shaft 4 in front of the nozzles 3 automatically lays the seedling-shielding strip 5 above the seedlings, while the rotation of the rotating shaft 4 behind the nozzles 3 automatically retracts the seedling-shielding strip 5. This ensures that the seedlings within the spray range of the nozzles 3 are protected by the seedling-shielding strip 5, greatly reducing the amount of herbicide adhering to the seedlings.

[0029] The seedling shade strip 5 is designed to move in real time so that the nozzle 3 and the seedling shade strip 5 always maintain relative movement. This is because if the seedling shade strip 5 were stationary, the nozzle 3 would continuously spray atomized herbicide onto a fixed area of ​​the seedling shade strip 5. The herbicide, initially atomized, would gradually accumulate in this area and drip downwards after being blocked. Since the seedlings are below the seedling shade strip 5, it would easily come into contact with the herbicide. However, in this embodiment, the seedling shade strip 5 is designed to move in real time, preventing herbicide accumulation and avoiding the problem of herbicide dripping.

[0030] It also includes a seedling-shading curtain 6, which is hinged to the edge of the seedling-shading strip 5. There are multiple seedling-shading curtains 6, which are evenly distributed along the length of the seedling-shading strip 5. Both sides of the seedling-shading strip 5 have the seedling-shading curtain 6. The seedling-shading curtain 6 hangs down by its own weight to block the sides of the seedlings. A seedling-shading space 7 is formed between the seedling-shading strip 5 and the seedling-shading curtain 6. The seedling-shading space 7 is used to accommodate the seedlings.

[0031] In this embodiment, to provide comprehensive and adequate protection for the seedlings, multiple seedling-shading curtains 6 are hinged to the edges of both sides of the seedling-shading strip 5. When the seedling-shading strip 5 is above the seedlings, the seedling-shading curtains 6 will automatically droop under the influence of gravity, thus covering both sides of the seedlings. The top seedling-shading strip 5 and the seedling-shading curtains 6 on both sides together form the seedling-shading space 7, within which the seedlings are fully protected. The seedling-shading curtains 6 are designed as multiple separate structures, ensuring that when the seedling-shading strip 5 is rolled up, the seedling-shading curtains 6 can also be rolled up together, without affecting the normal winding and unwinding of the seedling-shading strip 5.

[0032] It also includes a drive wheel 8, which is rotatably mounted on the mounting bracket 2. The drive wheel 8 is drivenly connected to the rotating shaft 4 and is used to contact the ground and roll on the ground.

[0033] In this embodiment, when the equipment is moving, the drive wheel 8 rolls on the ground. The drive wheel 8 and the rotating shaft 4 are driven by belt drive or chain drive. When the drive wheel 8 rolls, it drives the rotating shaft 4 to rotate, thereby achieving the effect of automatically laying the seedling shade belt 5 when the equipment is moving and stopping the laying of the seedling shade belt 5 when the equipment is stationary.

[0034] It also includes a lifting frame 9, which is slidably mounted on the frame 1, and the mounting frame 2 is rotatably mounted on the lifting frame 9.

[0035] In this embodiment, the lifting frame 9 and the mounting frame 2 are connected, enabling the lifting and rotation of the mounting frame 2. During the equipment's movement, once the seed-shading belt 5 is completely wrapped from the front rotating shaft 4 to the rear rotating shaft 4, the lifting frame 9 is first driven to rise, raising the seed-shading curtain 6 above the seedlings. Then, the mounting frame 2 is driven to rotate 180°, changing its front-to-back direction. The lifting frame 9 is then lowered, allowing the drive wheels 8 to contact the ground, and the equipment continues to move. No stopping is required; the seed-shading belt 5 can be flipped back and forth during operation, thus enabling its reuse.

[0036] It also includes a support frame 10 and a support shaft 11. The support frame 10 is slidably disposed relative to the mounting frame 2, and the support shaft 11 is rotatably disposed on the support frame 10. The support frame 10 and the support shaft 11 are both arranged in pairs, and the support shaft 11 is used to support the seedling shielding strip 5.

[0037] It also includes a guide post 12 and a telescopic cylinder 13. The guide post 12 is slidably mounted on the mounting frame 2, the support frame 10 is mounted on the guide post 12, and the telescopic cylinder 13 is mounted on the mounting frame 2. The telescopic end of the telescopic cylinder 13 acts on the support frame 10.

[0038] In this embodiment, to ensure the tension of the seedling-shading strip 5, a support frame 10 and a support shaft 11 are also provided. The support frame 10 is slidably mounted on the mounting frame 2 via the guide post 12. The telescopic end of the telescopic cylinder 13 is connected to the support frame 10 to drive the sliding of the support frame 10. The two support frames 10 are located on the front and rear sides respectively. The two support shafts 11 can support the seedling-shading strip 5 to keep it parallel to the ground. The support frame 10 can drive the support shaft 11 to slide, thereby changing the length of the section of the seedling-shading strip 5 parallel to the ground according to the spray range of the nozzle 3.

[0039] Furthermore, the two support frames 10 can slide independently, so the distance between each support shaft 11 and the nozzle 3 can be controlled individually. After the herbicide is sprayed, due to its mist-like nature, some of the herbicide will remain diffused in the air for a short period before falling. Because the equipment is in motion, to prevent the diffused herbicide from contacting the seedlings after the shade belt 5 leaves the seedlings, the support roller located behind the nozzle 3 can be slid to a farther position in advance, thereby extending the length of the horizontal section of the shade belt 5 and prolonging the time the seedlings are shaded, thus solving the aforementioned problem.

[0040] It also includes a medicine storage box 14 and a connecting hose 15. The medicine storage box 14 is mounted on the mounting frame 2. One end of the connecting hose 15 is connected to the medicine storage box 14, and the other end is used to connect to the nozzle 3. There are multiple nozzles 3, which are located on both sides of the seedling shielding strip 5.

[0041] It also includes a spray pipe 16, which is rotatably mounted on the mounting bracket 2, a nozzle 3 is mounted on the spray pipe 16, and a connecting hose 15 is connected to the spray pipe 16.

[0042] In this embodiment, a storage box 14 is provided on the mounting frame 2 for storing herbicides, and is connected to the spray pipe 16 via a connecting hose 15. Multiple nozzles 3 are provided along the length of the spray pipe 16 to increase the spraying range of the herbicide. The orientation of the nozzles 3 can also be adjusted by rotating the spray pipe 16, thereby adjusting the spraying angle of the herbicide as needed.

[0043] It also includes a connecting frame 17, which is disposed on the frame 1 and has a connecting hole 18 for connecting to the walking unit.

[0044] It also includes four traveling wheels 19, which are rotatably mounted on the frame 1 and are located at the four corners of the frame 1.

[0045] In this embodiment, a connecting frame 17 is provided at the front of the frame 1, and the connecting frame 17 is designed with connecting holes 18 to facilitate connection with tractors or other mobile agricultural implements. A traveling wheel 19 is also rotatably installed at each of the four corners of the frame 1 to contact the ground and roll on the ground, providing stable support for the overall equipment and ensuring the stability of the equipment during movement.

[0046] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
