[0032] Example 1:

[0033] like Figures 1 to 5 As shown, this embodiment provides a weed-clearing device for leek fields, including: a handle 1, which is U-shaped and horizontally positioned, with shoulder straps 2 placed on both sides of the middle of the U-shape; two sets of shoulder straps 2, which are attached to the handle 1 by two sets of circular Velcro; a sliding rod 3, which is welded from a set of thick cylinders and a set of thin cylinders, placed at an angle, with the thick cylinders fixed to one side of the middle of the handle 1, and a fixing mechanism provided at one end of the thin cylinders; and a fixing rod 31, which is a cylindrical sleeve, placed at an angle, and one end of which is slidably connected to the thin cylindrical end of the sliding rod 3.

[0034] In this embodiment, the fixing mechanism and the cutting device constitute a weed-clearing device for leek fields according to this application.

[0035] It should also be noted that the weed control device for leek fields described in this application can be a mechanical-physical weed control device, a chemically assisted weed control device, or a physical-energy weed control device, etc. Figure 1 In this embodiment, a weed-clearing device for leek fields is described as a mechanical and physical weed-clearing device. Of course, other types of weed-clearing devices for leek fields can also adopt similar structures, which will not be described in detail below.

[0036] Understandable Figure 1This illustration only shows some components of a weed-clearing device for leek fields. The actual shape, size, location, and construction of these components are not subject to change. Figure 1 Due to limitations, a weed-clearing device for leek fields can also include, compared to... Figure 1 More or fewer parts.

[0037] It should also be understood that the motor was purchased from the market and is common knowledge in this field. It is only used and not modified, so the control method and circuit connection will not be described in detail.

[0038] In this embodiment, the handle 1 is U-shaped and horizontally positioned, with two shoulder strap placement positions reserved on both sides of the U-shaped middle. The shoulder straps 2 are made of nylon and consist of two sets, attached to the pre-positioned positions on the handle 1 via two sets of circular Velcro straps. The sliding rod 3 is constructed by welding a set of thick and thin stainless steel cylinders, positioned at an angle. The thick cylinder is fixed to one side of the middle of the handle 1 by welding, and a fixing mechanism is provided at the end of the thin cylinder away from the thick cylinder. The fixing rod 31 has the same angle of inclination as the sliding rod 3, and one end of it is slidably connected to the thin cylindrical end of the sliding rod 3. The shoulder straps 2 are detachably connected to the handle 1 via Velcro straps for the user to carry the device. The sliding rod 3 and the fixing rod 31 slide together, allowing adjustment of their total length. This design enables portable carrying of the device and adapts to the different operating distance requirements of users.

[0039] Specifically, one end of the fixed rod 31 is also connected to a support plate 4. The support plate 4 is L-shaped and placed horizontally. The top middle of the support plate 4 is fixed to the end of the fixed rod 31 away from the sliding rod 3. Fixed shafts 401 are fixed on both sides of the top of the support plate 4. A set of rectangular grooves 40 are opened horizontally at both ends of the vertical surface of the support plate 4.

[0040] In this embodiment, a support plate 4 is welded to the end of the fixed rod 31 away from the sliding rod 3. The support plate 4 is made of steel plate and is L-shaped, placed horizontally. The top center of the support plate 4 is welded and fixed to the end of the fixed rod 31 away from the sliding rod 3. Two sets of cylindrical fixing shafts 401 are symmetrically welded and fixed to both sides of the top of the support plate 4. A set of rectangular grooves 40 are horizontally opened at both ends of the vertical surface of the support plate 4. The support plate 4 is indirectly connected to the sliding rod 3 through the fixed rod 31, and the fixing shafts 401 provide an installation base for subsequent components. This provides a stable installation carrier for the cutting device and protective components, ensuring the integrity of the structure.

[0041] Specifically, a rectangular block is fixed to one side of the middle of the horizontal end of the support plate 4. A protective cover 5 is fixed to the top of the rectangular block by bolts. A motor is installed inside the protective cover 5. A cutting device is connected to the bottom of the motor. A heat dissipation hole is opened on the outer side of the protective cover 5, and a filter screen is installed inside the heat dissipation hole.

[0042] In a preferred embodiment, a rectangular steel plate is welded and fixed to one side of the horizontal center of the support plate 4. A protective cover 5 is bolted to the top of the rectangular block. A micro motor is fixed inside the protective cover 5, and the bottom of the motor output shaft is connected to the cutting device via a coupling. Several sets of heat dissipation holes are evenly distributed on the outer side of the protective cover 5, and metal filter screens are fixed inside the heat dissipation holes. When the motor is powered on, it drives the cutting device to operate. The protective cover 5 isolates the motor from external impurities, the heat dissipation holes assist in motor heat dissipation, and the filter screens prevent weeds and dust from entering the interior of the protective cover 5. This achieves power drive for the cutting device, protects the motor from external interference, and extends the motor's service life.

[0043] Example 2:

[0044] Based on Embodiment 1, in order to more conveniently adjust and fix the sliding rod, a button 301 is provided in the fixing mechanism;

[0045] Specifically, the fixing mechanism includes: two sets of buttons 301, the inner ends of which are slidably connected to the circular grooves opened on both sides of the thin cylindrical end of the sliding rod 3, and the outer ends of which are slidably connected to several sets of circular grooves evenly opened on both sides of the fixing rod 31; and two sets of springs 302, which are respectively set inside the two sets of buttons 301, with one end of the spring 302 fixed to one end of the inner wall of the button 301, and the other end fixed to the circular groove on the sliding rod 3.

[0046] In this embodiment, the fixing mechanism includes buttons 301 and springs 302. Two sets of buttons 301 are made of plastic, with their inner ends slidably connected to circular grooves on both sides of the thin cylindrical end of the sliding rod 3, and their outer ends slidably engaged in several sets of evenly spaced circular grooves on both sides of the fixing rod 31. Two sets of springs 302 are made of metal, respectively disposed inside the two sets of buttons 301. One end of each spring 302 is welded to one end of the inner wall of the button 301, and the other end is welded to the bottom of the circular groove on the sliding rod 3. Pressing the button 301 compresses the spring 302, causing the button 301 to disengage from the circular groove of the fixing rod 31. Sliding the sliding rod 3 to adjust the relative position of the sliding rod 3 and the fixing rod 31, and releasing the button 301, the spring 302 returns to its original position, pushing the button 301 into the corresponding circular groove, thus fixing the length. This allows for quick adjustment and fixing of the overall length of the device, making it convenient to operate and suitable for users of different heights.

[0047] Specifically, L-shaped plates 41 are provided on both sides of the top of the support plate 4, and a sliding groove 410 is provided on the top of the L-shaped plate 41. The fixed shaft 401 can slide in the sliding groove 410, and the top of the fixed shaft 401 can be locked with a nut. A fixing block 411 is installed on one side of the inner wall of the L-shaped plate 41, and the fixing block 411 is slidably connected in the rectangular groove 40.

[0048] With this configuration, two sets of L-shaped steel plates 41 are symmetrically arranged on both sides of the top of the support plate 4. A sliding groove 410 is formed on the top of each L-shaped plate 41, allowing the fixed shaft 401 to slide horizontally within it. A nut is threaded onto the top of the fixed shaft 401; tightening the nut secures the L-shaped plate 41. A rectangular metal fixing block 411 is welded to one side of the inner wall of the L-shaped plate 41, and this fixing block 411 is slidably connected to the rectangular groove 40 on the top of the support plate 4. Loosening the nut on the top of the fixed shaft 401 allows the L-shaped plate 41 to be pushed, causing the fixing block 411 to slide along the rectangular groove 40. This adjusts the spacing of the L-shaped plates 41. Once in place, tightening the nut secures the L-shaped plates 41. Adjusting the position of the L-shaped plates 41 indirectly adapts to the needs of different row spacings in leek fields, improving the versatility of the device.

[0049] Example 3:

[0050] Based on Embodiment 2, in order to synchronously adjust the spacing between the blades, a sliding blade 62 is provided inside the cutting device;

[0051] Specifically, the cutting device includes: a connecting column 6, with a rectangular block passing through one side of the rotating connecting support plate 4 at the top and connected to the motor key inside the protective cover 5, and outer blades 61 installed on both sides of the middle part of the connecting column 6; the outer blade 61 has a sliding groove 610 opened in the middle of the top along its length direction, and a sliding blade 62 is provided in the sliding groove 610, and a set of bolts is provided in the middle of both sides of the outer blade 61.

[0052] The cutting device includes a connecting column 6 and outer blades 61. The connecting column 6 is made of metal, with its top penetrating and rotatably connected to a rectangular block on one side of a support plate 4 via a bearing. The top of the connecting column 6 is keyed to the motor output shaft inside the protective cover 5. Two sets of stainless steel outer blades 61 are symmetrically welded and fixed on both sides of the middle of the connecting column 6. A rectangular sliding groove 610 is formed along the length of the top center of each outer blade 61, and a stainless steel sliding blade 62 is placed in the sliding groove 610. A set of bolts is threaded to the middle of each side of the outer blade 61. The motor drives the connecting column 6 to rotate, causing the outer blades 61 and sliding blades 62 to rotate at high speed, thus cutting weeds. The bolts can restrict the position of the sliding blades 62 in the sliding groove 610. By rapidly cutting weeds with rotating blades, the weeding efficiency is improved, and the position of the sliding blades 62 can be adjusted to adapt to different cutting width requirements.

[0053] Specifically, the sliding blades 62 are slidably connected in the sliding groove 610, and several sets of threaded holes are evenly opened on the side of the sliding blades 62, which can be connected to the bolts on both sides of the outer blades 61.

[0054] In this embodiment, the sliding blade 62 is made of stainless steel and is slidably connected to the sliding groove 610 of the corresponding outer blade 61. Several sets of threaded holes are evenly distributed along the length of the side of the sliding blade 62, which can be threadedly connected to the bolts on both sides of the outer blade 61. Loosen the bolts on both sides of the outer blade 61, push the sliding blade 62 to slide along the sliding groove 610, adjust the extension length of the sliding blade 62 so that the corresponding threaded holes on the sliding blade 62 are aligned with the bolts, and tighten the bolts to fix the sliding blade 62. This allows for flexible adjustment of the overall cutting width of the cutting device, precisely adapting to different row spacings in leek fields, avoiding accidental cutting of leeks, and improving weeding accuracy.

[0055] In actual use, the user attaches the shoulder strap 2 to the handle 1, slings it over their shoulder, presses the two sets of buttons 301, and the spring 302 contracts, causing the buttons 301 to retract into the fixing rod 31. Slightly rotating the sliding rod 3 causes the buttons 301 to deviate from the circular groove on the fixing rod 31, pulling the sliding rod 3 outwards. After adjusting the sliding rod 3 to a suitable length, it is rotated back to allow the buttons 301 to engage with one of the other circular grooves on the fixing rod 31, thus fixing the position of the sliding rod 3. This design allows the user to adjust the height of the device according to their height, making it more versatile. Finally, the motor inside the protective cover 5 is activated, driving the connecting column 6. The two sets of outer blades 61 rotate at high speed to cut weeds. When the gap is too small, the motor can be stopped, the nut on the fixed shaft 401 can be turned and the two sets of L-shaped plates 41 can be moved to the appropriate position. At this time, the fixed block 411 slides in the rectangular groove 40, which can limit the displacement of the L-shaped plate 41. Then, the bolts are tightened to fix the position of the L-shaped plate 41. The bolts on both sides of the outer blades 61 are removed, the two sets of sliding blades 62 can be moved to the appropriate position and the bolts are tightened back. The distance between the blades can be adjusted. This design can adapt to different spacing cuts, and the protective cover on the outside of the blades can be expanded and contracted to prevent weeds from flying around and protect the user from injury.

[0056] 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.
