Abstract
Description
Technical Field
[0001] This utility model relates to the field of weeding device technology, and in particular to a weeding device. Background Technology
[0002] Weeds are generally non-cultivated wild plants or plants that have no effect on humans. Overgrown weeds can lead to a decrease in crop yield and quality. In order to achieve the sustainable development of farmland, gardens and orchards, weeding operations are often required.
[0003] Existing weed control methods include lawnmower weeding, herbicide weeding, and manual weeding. Lawnmowers cannot eradicate weeds completely and require frequent weeding. Herbicide residues cause chemical pollution to crops and soil, as well as environmental pollution, leading to increased herbicide resistance in weeds and an expanded resistance spectrum. Although manual weeding is effective, it has problems such as high labor intensity, low work efficiency, and potential harm to the operator. Utility Model Content
[0004] To address the aforementioned issues, this application provides a reasonably structured weeding device that effectively reduces the manual labor intensity during weeding, avoids frequent bending movements by the operator, and helps improve efficiency, making it highly practical.
[0005] The technical solution adopted in this utility model is as follows:
[0006] A weeding device includes an extension rod for hand gripping. A fixed foot and a fixed tooth are installed at the bottom end of the extension rod. A movable foot is rotatably mounted on the middle of the fixed tooth via a pedal pivot. A movable tooth is rotatably mounted on the movable foot via a tooth pivot. A lateral distance is provided between the tooth pivot and the pedal pivot. The movable tooth overlaps and contacts the fixed tooth.
[0007] As a further improvement to the above technical solution:
[0008] The fixed tooth extends laterally in the middle to form a protrusion, and the movable tooth has a "7" shaped structure, with the horizontal part of the movable tooth overlapping and contacting the upper part of the protrusion.
[0009] The movable tooth is movable tooth one, or the movable tooth includes movable tooth one and movable tooth two; the horizontal part of movable tooth one overlaps and contacts the protrusion of the fixed tooth, and the horizontal part of movable tooth two overlaps and contacts the horizontal part of movable tooth one.
[0010] The first movable tooth, with its corresponding tooth rotation axis as the center and the overlapping point in contact with the fixed tooth as the fulcrum, closes towards the bottom end of the fixed tooth to clamp; the second movable tooth, with its corresponding tooth rotation axis as the center and the overlapping point in contact with the first movable tooth as the fulcrum, moves towards the clamping point of the first movable tooth and the fixed tooth.
[0011] The first movable tooth and the fixed tooth are arranged opposite each other in the same plane; the first tooth shaft corresponding to the first movable tooth is parallel to the axis of the pedal shaft; the second movable tooth is arranged in a plane perpendicular to the first movable tooth and the fixed tooth, and the second tooth shaft corresponding to the second movable tooth is perpendicular to the axis of the first tooth shaft.
[0012] The number of movable teeth is two, arranged opposite each other, with the horizontal portions of the two movable teeth overlapping each other on the protrusion of the fixed teeth.
[0013] The movable teeth and fixed teeth have gradually decreasing cross-sectional dimensions from top to bottom, forming a downward-facing tooth-like structure. The inner surface of the tooth-like structure forms a wave-shaped or sawtooth-shaped clamping surface.
[0014] It also includes a mowing board, which is fitted around the movable and fixed teeth in the circumferential direction; the mowing board extends upward via a connecting rod to form a handle, which is fitted onto an extension rod.
[0015] The end of the movable foot extends laterally toward the extension rod to form a support part; the extension rod is inclined to cause the end of the support part to contact the ground and bear force, or, an extension support is installed on the support part via a support pivot, and the end of the extended support contacts the ground and bears force.
[0016] The fixed foot and movable foot support sections are located on both sides of the extension rod.
[0017] Compared with the prior art, the present invention has the following beneficial effects:
[0018] When this utility model is in use, a downward force is applied by a fixed foot or a movable foot, inserting the fixed tooth and movable tooth downward into the soil. The deflection extension rod causes the movable foot to contact the ground and receive a reverse force, causing it to swing upward relative to the pedal pivot. This causes the tooth pivot to swing downward relative to the fixed tooth, so that the movable tooth, supported by its contact point with the fixed tooth, rotates towards the fixed tooth with the tooth pivot as its center, until the bottom ends of the fixed tooth and movable tooth come close to each other to achieve the clamping and weeding action. This effectively reduces the manual labor intensity when weeding, avoids the operator's frequent bending movements, and helps to improve the efficiency of the operation. It is highly practical.
[0019] This utility model also has the following advantages:
[0020] Depending on the actual weeding needs, one, two, or three movable teeth can be set to match the action of the fixed teeth to achieve weeding;
[0021] After the grass is gripped and pulled up by the movable and fixed teeth, the grass can be pushed downwards and detached from the movable and fixed teeth by the downward relative movement of the grass-pulling plate, which facilitates subsequent continuous grass-pulling operations.
[0022] The fixed foot design allows the operator to easily apply downward pressure to quickly insert the fixed and movable teeth into the soil. Attached Figure Description

[0031] The specific embodiments of this utility model are described below with reference to the accompanying drawings.
[0032] like Figure 1 and Figure 2 As shown, a weeding device in this embodiment includes an extension rod 1 for hand gripping. A fixed foot 6 and a fixed tooth 3 are installed at the bottom end of the extension rod 1. A movable foot 4 is rotatably installed in the middle of the fixed tooth 3 via a pedal shaft 41. A movable tooth is rotatably installed on the movable foot 4 via a tooth shaft. A lateral distance is provided between the tooth shaft and the pedal shaft 41, and the movable tooth overlaps and contacts the fixed tooth 3.
[0033] In use, by applying downward force through the fixed foot 6 or the movable foot 4, the fixed tooth 3 and the movable tooth are inserted downward into the soil. The deflection extension rod 1 causes the movable foot 4 to contact the ground and be subjected to a reverse force, causing it to swing upward relative to the pedal pivot 41. This causes the tooth pivot to swing downward relative to the fixed tooth 3, so that the movable tooth rotates towards the fixed tooth 3 with its contact point with the fixed tooth 3 as support, until the bottom ends of the fixed tooth 3 and the movable tooth come close to each other to achieve the clamping and weeding action.
[0034] The fixed tooth 3 extends laterally in the middle to form a protrusion 31, and the movable tooth has a "7" shaped structure. The horizontal part of the movable tooth overlaps and contacts the upper part of the protrusion 31; thus effectively ensuring the overlap contact between the movable tooth and the fixed tooth 3, and effectively ensuring that they move closer to each other and are clamped by using the overlap point as a support point.
[0035] like Figure 3 and Figure 4 As shown, the movable tooth is movable tooth 7, or the movable tooth includes movable tooth 7 and movable tooth 8; the horizontal part of movable tooth 7 overlaps and contacts the protrusion 31 of fixed tooth 3, and the horizontal part of movable tooth 8 overlaps and contacts the horizontal part of movable tooth 7.
[0036] In one embodiment, only the movable tooth 7 is provided as a movable tooth that matches the action of the fixed tooth 3, and the clamping of the two action points is achieved by the movable tooth 7 moving closer to the fixed tooth 3.
[0037] In another embodiment, movable tooth 8 can be provided at the same time as movable tooth 7, thereby increasing the clamping points and ensuring the clamping effect when weeding.
[0038] Movable tooth 7, with its corresponding tooth pivot 71 as the center and the overlapping point in contact with fixed tooth 3 as the fulcrum, closes towards the bottom of fixed tooth 3 to clamp; movable tooth 8, with its corresponding tooth pivot 81 as the center and the overlapping point in contact with movable tooth 7 as the fulcrum, moves towards the clamping point of movable tooth 7 and fixed tooth 3; thus realizing the clamping action of movable tooth and fixed tooth 3 when weeding.
[0039] Movable tooth 7 and fixed tooth 3 are arranged opposite each other in the same plane; the axial direction of tooth shaft 71 corresponding to movable tooth 7 is parallel to the axial direction of pedal shaft 41; movable tooth 8 is arranged in a plane perpendicular to movable tooth 7 and fixed tooth 3, and the axial direction of tooth shaft 81 corresponding to movable tooth 8 is perpendicular to the axial direction of tooth shaft 71.
[0040] In one embodiment, for example, if only the movable tooth 7 is provided to match the fixed tooth 3 for weeding and clamping, it will clamp the grass in the opposite direction to ensure the reliability of clamping when weeding.
[0041] In another embodiment, in addition to providing movable tooth 7 and fixed tooth 3, one or two movable teeth 8 are also provided in the vertical direction, thereby effectively increasing the clamping points for the grass.
[0042] The number of movable teeth 8 is two, arranged opposite each other. The horizontal parts of the two movable teeth 8 are arranged side by side and overlapped on the protrusion 31 of the fixed tooth 3, which effectively ensures the reliability of their operation when two movable teeth 8 are set.
[0043] In practice, one, two, or three movable teeth can be set up to match the action of the fixed teeth to achieve weeding, depending on the actual needs of the weeding operation.
[0044] In this embodiment, corresponding limiting and resetting structures can be provided at the pedal pivot 41, such as a stop limiting block to prevent the movable pedal 4 from rotating downward relative to the extension rod 1, and an elastic element to facilitate resetting after the movable pedal 4 rotates upward relative to the extension rod 1, so as to facilitate and assist in actual operation and use.
[0045] In this embodiment, a corresponding elastic reset structure can be installed at the tooth pivot of the movable tooth to facilitate the reset of the movable tooth after weeding.
[0046] The cross-sectional dimensions of the movable teeth and fixed teeth 3 gradually decrease from top to bottom, forming a downward-facing tooth-like structure. The inner surface of the tooth-like structure forms a wave-shaped or sawtooth-shaped clamping surface, which effectively ensures the clamping effect.
[0047] It also includes a mowing board 2, which is fitted around the movable teeth and fixed teeth 3 in a circumferential direction; the mowing board 2 extends upward through the connecting rod 21 to form a handle 22, which is fitted onto the extension rod 1.
[0048] After the grass is gripped and pulled up by the movable teeth and fixed teeth 3, the grass can be pushed downwards and detached from the movable teeth and fixed teeth 3 by the downward relative movement of the grass-pulling plate 2, which facilitates subsequent continuous grass-pulling operations.
[0049] The end of the movable foot 4 extends laterally toward the extension rod 1 to form a support part; the extension rod 1 is tilted to make the end of the support part contact the ground and bear force, or, an extension support 5 is installed on the support part via a support pivot 51, and the end of the extended support 5 contacts the ground and bears force.
[0050] In this embodiment, during actual use, the lateral swing of the extension rod 1 causes the movable foot 4 to contact the ground, thereby enabling the movable tooth to move towards the fixed tooth 3 for clamping. At the same time, the swing of the extension rod 1 also causes the fixed tooth 3 to move relative to the ground, similar to the fixed tooth 3 inserted into the soil swinging upwards, thus effectively ensuring that the weeding action is achieved while clamping.
[0051] In this embodiment, the movable foot 4 can be set to have a sufficient lateral length for use, depending on the actual situation. Alternatively, the length of the movable foot 4 can be satisfied by setting the extension support 5. The extension support 5 can be unfolded or retracted relative to the movable foot 4, which facilitates the daily use and storage of the weeding equipment.
[0052] In this embodiment, a corresponding limiting structure can be installed between the extension support 5 and the movable foot 4 to ensure the extension support 5 in its unfolded and retracted state relative to the movable foot 4.
[0053] The fixed foot 6 and the movable foot 4 are located on both sides of the extension rod 1.
[0054] The fixed foot 6 allows the operator to easily apply force by stepping down to quickly insert the fixed tooth 3 and the movable tooth into the soil; force can also be applied by stepping on the movable foot 4.
[0055] Of course, in practice, the positions of the fixed foot 6 and the movable foot 4 support relative to the extension rod 1 can be arranged in other ways, as long as downward force can be applied through the fixed foot 6 and the setting of the fixed foot 6 does not affect the movable foot 4.
[0056] The method of using this utility model is as follows:
[0057] The operator steps down on the fixed foot 6, causing the fixed tooth 3 and the movable tooth to insert downwards into the soil, placing the stems and roots of the weeds to be removed between the movable tooth and the fixed tooth 3; lateral force is applied to the extension rod 1 to make it swing sideways, as... Figure 5 As shown, the end of the movable foot 4 contacts the ground and is subjected to a reaction force, causing it to swing relative to the extension rod 1. This causes the movable tooth to rotate toward the fixed tooth 3 with the overlapping point as support and the corresponding tooth rotation axis as the center, until the bottom ends of the fixed tooth 3 and the movable tooth come close to each other to achieve clamping. At the same time, the swing of the extension rod 1 also causes the fixed tooth 3 to tilt upward relative to the ground, thus effectively ensuring that the weeding action is achieved while clamping.
[0058] After pulling up the grass clips, as Figure 6 As shown, force can be applied to the handle 22, and the connecting rod 21 will cause the weeding plate 2 to move downward relative to the fixed tooth 3 and the movable tooth, thereby pushing the grass away from the weeding device to achieve weed removal, so as to facilitate continuous weeding action.
[0059] This invention effectively reduces the manual labor intensity of weeding, avoids frequent bending over movements by the operator, and helps to improve efficiency, making it highly practical.
[0060] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
