Description

Technical Field

[0001] The present invention relates to the technical field of gardening and greening, in particular to a gardening and greening weeding device. Background Art

[0002] In the field of landscaping, various ornamental planting areas are often planned to enhance the landscape's aesthetic appeal, creating unique landscapes by planting specific plant species. Within these specialized landscape plantings, weeds can occasionally grow, disrupting the landscape's aesthetics and requiring prompt removal. However, current mechanical weed removal devices are typically used to weed large lawns and green belts. Because the weeds are difficult to control and their bulk is large, they are not suitable for weeds intermingled with ornamental plants, potentially damaging them. Therefore, these weeds can only be removed manually, which is labor-intensive and time-consuming. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a gardening weeding device to address the above-mentioned technical deficiencies. The device can be used to remove weeds mixed in ornamental plants, is easy to operate, provides good protection for ornamental plants, and saves time and effort.

[0004] The technical solution adopted by the present invention is to provide a gardening weeding device, comprising a vertically arranged mounting rod; a fixing frame connected to the lower end of the mounting rod; a through slot vertically opened in the middle of the mounting rod; the through slot radially extending through the left and right sides of the mounting rod; and a weeding range adjustment component provided on the fixing frame. The weeding range adjustment assembly includes limiting rods symmetrically arranged on the left and right sides of the fixing frame with the mounting rod as the symmetry axis; the upper ends of the limiting rods are hinged to the fixing frame; the lower end of the fixing frame is connected to a telescoping device; the telescoping end of the telescoping device is vertically fixed downward to a support; connecting rods are respectively provided on the left and right sides of the support; one end of the connecting rod is hinged to the support, and the other end is hinged to the upper part of the limiting rod on the same side; a weeding action assembly is provided between the limiting rod and the through slot; The weeding action component includes a first guide wheel rotatably connected to the lower part of the limiting rod and an extension bracket slidably arranged in the through slot; the left and right ends of the extension bracket are respectively rotatably connected to the second guide wheels; the axial directions of the first guide wheel and the second guide wheel are both arranged along the front-back direction; the second guide wheel on the right side is driven by a power motor connected to the extension bracket; the lower end of the extension bracket and the lower end of the through slot are connected by a compression spring; the weeding action component also includes a ring-shaped cutting line; the cutting line is tensioned and passes around all the first guide wheels and the second guide wheels in sequence.

[0005] To further optimize this technical solution, an auxiliary guide wheel is rotatably connected to the upper side of a limiting rod of a landscaping weeding device; the axial direction of the auxiliary guide wheel is parallel to the axial direction of the first guide wheel; and the cutting line correspondingly passes around the side of the auxiliary guide wheel close to the limiting rod.

[0006] To further optimize the technical solution, a protective sleeve frame is fixed to the outside of a limiting rod of a landscaping weeding device; and a cutting line passes through the inside of the protective sleeve frame.

[0007] To further optimize the technical solution, a landscaping weeding device has a lower end of a limiting rod threadedly connected to a height-raising sleeve foot.

[0008] To further optimize the technical solution, a hand-held sleeve is fixed to the upper end of the mounting rod of a landscaping weeding device.

[0009] To further optimize the technical solution, a landscaping weeding device has control buttons connected to the upper side of a mounting rod for controlling the extension and retraction of the telescopic device and the start and stop of the drive motor.

[0010] The beneficial effects of the present invention are: The telescopic device drives the support to move up and down, and combined with the linkage of the connecting rod, the limiting rods on both sides can be relatively separated or gathered, thereby adjusting the weeding range so that the range can be more adapted to the area where weeds grow in the ornamental plants.

[0011] The cutting line is in a tensioned state and passes around the first guide wheel and the second guide wheel in sequence. The second guide wheel on the right is driven by a power motor connected to the extension bracket. The power motor can drive the cutting line to reciprocate, thereby cutting the weeds with the help of the cutting line between the two first guide wheels.

[0012] Since the limiting rods on both sides limit the range of the effective cutting part of the cutting line, more effective protection can be achieved for the ornamental plants, and accidental damage to the ornamental plants around the weeds can be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0015] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0016] like Figure 1 As shown, a landscaping weeding device includes a vertically arranged mounting rod 1; a fixing frame 2 is connected to the lower end of the mounting rod 1; a through slot 3 is vertically opened in the middle of the mounting rod 1; the through slot 3 radially passes through the left and right sides of the mounting rod 1; and a weeding range adjustment component is provided on the fixing frame 2; like Figure 1-2 As shown, the weeding range adjustment assembly includes a limiting rod 4 symmetrically arranged on the left and right sides of the fixing frame 2 with the mounting rod 1 as the symmetry axis; the upper end of the limiting rod 4 is hinged to the fixing frame 2; the lower end of the fixing frame 2 is connected to a telescoping device 5; the telescopic end of the telescoping device 5 is fixed vertically downward to a support 6; a connecting rod 7 is respectively provided on the left and right sides of the support 6; one end of the connecting rod 7 is hinged to the support 6, and the other end is hinged to the upper part of the limiting rod 4 on the same side; a weeding action assembly is provided between the limiting rod 4 and the through slot 3; like Figure 2-3 As shown, the weeding action component includes a first guide wheel 8 rotatably connected to the lower part of the limiting rod 4 and an extension bracket 9 slidably arranged in the through slot 3; the left and right ends of the extension bracket 9 are respectively rotatably connected to the second guide wheels 10; the axial directions of the first guide wheel 8 and the second guide wheel 10 are both arranged along the front and rear directions; the second guide wheel 10 on the right is driven by a power motor 11 connected to the extension bracket 9; the lower end of the extension bracket 9 and the lower end of the through slot 3 are connected by a compression spring 12; the weeding action component also includes a ring-shaped cutting line 13; the cutting line 13 is in a tensioned state and passes around all the first guide wheels 8 and the second guide wheels 10 in sequence.

[0017] When weeds are found mixed in the ornamental plants, first adjust the weeding range adjustment component of the device to a range that is compatible with or smaller than the weed growth area (not larger than the weed growth area) according to the weed growth range, and then perform the weeding operation through the weeding action component.

[0018] When adjusting the weeding range, the action of the telescopic device 5 drives the support 6 to move up and down, and the linkage of the connecting rod 7 causes the limiting rods 4 on both sides to move away from or together relatively, so that the area between the two limiting rods 4 is the weeding range.

[0019] During the above action, since the cutting line 13 is in a tensioned state and passes around all the first guide wheels 8 and the second guide wheels 10 in sequence, when the two limiting rods 4 are relatively far away, the part of the cutting line 13 between the two limiting rods 4 becomes longer. Since the overall length of the cutting line 13 is fixed, the cutting line 13 will compress the compression spring 12 downward through the extension bracket 9 at this time. The compression spring 12 has a reaction force on the cutting line 13, which can still ensure the tension of the cutting line 13.

[0020] When weeding, it is only necessary to start the power motor 11, which drives the second guide wheel 10 on the right to rotate, thereby driving the cutting line 13 to reciprocate, and the weeds are cut off by the cutting line 13 between the two first guide wheels 8.

[0021] Through the above operation, weeds mixed in a small area can be removed. Moreover, the linear cutting method of the cutting line 13 replaces the traditional blade cutting method, which can further save space, facilitate accurate observation of the weeding area during weeding, make the weeding position more accurate, facilitate refined operation, achieve more effective protection of ornamental plants, and reduce accidental damage to ornamental plants around the weeds. In addition, the use of the cutting line 13 can reduce the weight of the entire device, making manual operation more labor-saving.

[0022] The cutting line 13 can be made of high-strength material such as nylon to ensure durability.

[0023] The power motor 11 can be in the form of a reduction motor. Under the premise of ensuring the weed cutting efficiency, the cutting line 13 does not need to cut too fast, so as to improve safety.

[0024] like Figure 2 As shown, an auxiliary guide wheel 14 is rotatably connected to the upper side of the limiting rod 4; the axial direction of the auxiliary guide wheel 14 is parallel to the axial direction of the first guide wheel 8; the cutting line 13 is correspondingly routed around the side of the auxiliary guide wheel 14 closest to the limiting rod 4. The provision of the auxiliary guide wheel 14 prevents the cutting line 13 from being too far away from the limiting rod 4 when it passes outside the limiting rod 4, thereby increasing the risk of damaging surrounding ornamental plants. Of course, the first guide wheel 8, the second guide wheel 10, and the auxiliary guide wheel 14 in this application are all grooved wheel structures, which can prevent the cutting line 13 from escaping during the weeding process.

[0025] like Figure 2 As shown, a protective sleeve 15 is fixed to the outside of the limiting rod 4; the cutting line 13 passes through the inside of the protective sleeve 15. The protective sleeve 15 further restrains and protects the cutting line 13, preventing the cutting line 13 from deviating from its installed position due to accidental operation during storage or transportation of the device (primarily preventing it from coming off the auxiliary guide wheel 14).

[0026] like Figure 2 As shown, the lower end of the limiting rod 4 is threadedly connected with a heightening sleeve foot 16. By installing the heightening sleeve frame, the cutting height of the cutting line 13 can be increased, which is applicable to situations where there are certain height obstacles in the weeding position.

[0027] like Figure 1 As shown, a hand-held sleeve 17 is fixed to the upper end of the mounting rod 1, which is convenient for the operator to hold for weeding operations.

[0028] like Figure 1As shown, the upper side of the mounting rod 1 is connected with a control button 18 for controlling the telescopic device 5 and the start and stop of the drive motor. The corresponding control button 18 can be used to control the work of the telescopic device 5 and the drive motor at any time to reduce the occurrence of operational accidents.

[0029] It will be understood that the present invention is described by way of some embodiments, and it will be appreciated by those skilled in the art that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
