Description

Technical Field

[0001] This invention relates to the field of garden and horticulture equipment technology, and in particular to a multi-angle weeding machine. Background Technology

[0002] In garden and horticulture maintenance, weed control is a crucial step in ensuring healthy plant growth and enhancing the aesthetic appeal of the landscape. Currently, weeding machines are used for weed removal. However, existing weeding machines on the market have many limitations in their structural design, making it difficult to meet the weed control needs of complex garden scenarios. Specific problems are as follows: Most existing weeders have a fixed connection structure between the machine body and the weeding component. The weeding component can only weed horizontally or at a small angle, which is difficult to adapt to complex terrain. For example, when weeding between flower beds, the fixed angle can easily scratch the branches and leaves of the flowers. When weeding on slopes, operators need to bend over or tilt the machine body, which is not only laborious but also easily leads to incomplete weeding. When clearing weeds around flower pots, the angle is difficult to adjust, which can easily cause collisions with flower pots or damage to the plant roots, greatly limiting its applicability. The height of the weeding mechanism in existing weeders is mostly manually adjustable, requiring the machine to be stopped and fixed by a knob or pin. The adjustment precision is low, making it difficult to accurately adapt to the height of the weeds. This results in incomplete removal of low-lying weeds or uneven cutting of tall weeds, affecting the weeding effect. Summary of the Invention

[0003] This invention relates to a multi-angle weeding machine. This multi-angle weeding machine achieves efficient and flexible weeding through multi-structure collaboration: In the basic support structure, the sliding hole and the first locking rod cooperate to quickly adjust the roller height, adapting to complex terrain and ensuring equipment stability; the height adjustment mechanism uses an electric motor and a threaded rod to flexibly adjust the weeding height, and a reinforcing plate ensures stable operation; the angle adjustment mechanism uses a rotating seat and a locking sleeve to quickly adjust and lock the weeding angle without tools, adapting to flower beds, slopes, and other scenarios; the weeding mechanism has stable power transmission, ensuring efficient operation of the weeding blades; the locking structure double-positions the weeding blades, making disassembly and maintenance convenient; the vortex channel reduces grass clippings adhesion, improving weeding efficiency. In the second embodiment, the storage shell can hold a battery or spare tools, further enhancing the equipment's practicality and adaptability to various scenarios.

[0014] Furthermore, a set of swirling grooves arranged in a ring array are respectively opened at the bottom position of the support plate and the second locking rod.

[0015] This invention provides a multi-angle weeding machine, which has the following beneficial effects: The invention features a first locking rod and a support spring that allow for quick adjustment of the roller height, ensuring the lawnmower can be placed stably on uneven ground. The support spring pushes the locking rod to lock the stable seat, allowing for height adjustment without additional tools. This convenient operation is suitable for complex terrains such as lawns and flower beds in gardens.

[0016] The height adjustment mechanism is driven by the first electric motor to rotate the threaded rod, which in turn moves the lifting plate vertically along the first positioning rod, so as to realize the flexible adjustment of the height of the weeding mechanism. It can be precisely adapted to the height of the weeds and can efficiently remove both low-lying and tall weeds.

[0017] The rotating seat of the positioning frame cooperates with the rotating hole of the lifting plate, allowing the weeding mechanism to rotate and adjust the angle flexibly, adapting to special scenarios such as gaps in flower beds and slopes, and avoiding damage to flowers or failure to fit the slope for weeding during operation; The locking sleeve works in conjunction with the locking groove and locking block of the rotating seat, and with the automatic locking function of the support spring, the locking can be completed by releasing the locking sleeve after adjusting the angle. There is no need to manually tighten the bolts. Pulling the locking sleeve will unlock the mechanism, which greatly improves the angle adjustment efficiency and ensures the stability of the weeding mechanism angle.

[0018] A second locking lever is installed to vertically position the weeding blade. This dual positioning ensures that the weeding blade is securely installed. The locking pin works with the connecting plate to quickly lock the weeding blade. During disassembly, the weeding blade can be removed simply by pulling the locking pin, without the need for tools. This facilitates the replacement and maintenance of the weeding blade and reduces the difficulty of operation.

[0019] The annular array of swirling grooves at the bottom of the support plate and the second locking rod guides the airflow when the weeding blade rotates. The airflow reduces the adhesion of grass clippings to the surface of the weeding blade, preventing grass clippings from tangling and affecting weeding efficiency. At the same time, it reduces the cutting resistance of the weeding blade, improving the overall work efficiency and weeding effect. Attached Figure Description

[0025] Example 1: Please refer to Figures 1 to 10 : This invention proposes a multi-angle weed cutter, comprising: a support base plate 1; a control frame 102 mounted on one side of the support base plate 1; a storage housing 101 located at the upper end of the support base plate 1; four vertically oriented stabilizing seats 2 mounted on the side of the support base plate 1; a rotatably connected roller 201 mounted at the bottom of each stabilizing seat 2; a first locking rod 3 installed between the support base plate 1 and the stabilizing seats 2; four rectangular sliding holes formed on the side of the support base plate 1 through which the stabilizing seats 2 pass; four L-shaped first positioning plates 103 on the side of the support base plate 1; a sliding hole on one side of each first positioning plate 103; and a set of locking holes on the inner side of each stabilizing seat 2 and on the side of the support base plate 1, the locking holes of the stabilizing seats 2 being vertically evenly distributed. The first locking rod 3 passes through the interior of the sliding hole and the locking hole in sequence. A retaining ring is provided on the outer side of the first locking rod 3. A support spring is installed on the outer side of the first locking rod 3. The support spring is located between the retaining ring and the first positioning plate 103. Specifically, the rectangular sliding hole provides vertical sliding guidance for the stabilizing seat 2, ensuring that the stabilizing seat 2 moves only up and down along the sliding hole; the first positioning plate 103 provides installation support for the first locking rod 3. The first locking rod 3 passes through the sliding hole and the locking hole in sequence, which can lock the height position of the stabilizing seat 2 to adapt to different flat surfaces; the support spring pushes the first locking rod 3 through the retaining ring to always insert it into the locking hole, preventing the first locking rod 3 from loosening and ensuring the height of the stabilizing seat 2 is locked stably. At the same time, pulling the first locking rod 3 can release the lock of the stabilizing seat 2, which facilitates quick adjustment of the height of the stabilizing seat 2 and the roller 201. In this embodiment, a first electric motor 401 is installed at the bottom of the supporting base plate 1, a lifting plate 405 is installed on one side of the supporting base plate 1, and a reinforcing plate 404 is installed on the top of the lifting plate 405. A set of bolt mounting holes are opened on one side of the reinforcing plate 404. A vertical threaded rod 402 is installed on the outer side of the drive shaft of the first electric motor 401. A vertical first positioning rod 403 is provided above the supporting base plate 1. The first positioning rod 403 is located on one side of the threaded rod 402. A threaded hole corresponding to the threaded rod 402 is opened in the middle of the lifting plate 405, and a sliding hole corresponding to the first positioning rod 403 is opened on one side of the lifting plate 405. The first positioning rod 403 passes through the interior of the sliding hole, and the threaded rod 402 passes through the threaded hole. Inside, the first electric motor 401, threaded rod 402, first positioning rod 403, reinforcing plate 404, and lifting plate 405 work together to form a height adjustment mechanism 4. Specifically, the first electric motor 401 drives the threaded rod 402 to rotate, which in turn drives the lifting plate 405 to move vertically through the threaded hole, thereby adjusting the height of the weeding mechanism 6 to meet the needs of weed removal at different heights. A set of rotating holes is opened on one side of the reinforcing plate 404, and the tops of the threaded rod 402 and the first positioning rod 403 extend into the rotating holes. Specifically, the rotating holes provide support and positioning for the tops of the threaded rod 402 and the first positioning rod 403, preventing the tops of the threaded rod 402 and the first positioning rod 403 from shaking, and further improving the stability of the height adjustment mechanism 4. In this embodiment, a positioning frame 501 is installed on the outer side of the lifting plate 405, and a second electric motor 601 is installed at the bottom of the positioning frame 501. A rotating seat 502 is provided on one side of the positioning frame 501. The rotating seat 502 has a cylindrical structure. A rotating hole corresponding to the rotating seat 502 is opened on one side of the lifting plate 405. The rotating seat 502 passes through the interior of the rotating hole. A rotating groove with an annular structure is opened on the outer periphery of the rotating seat 502. A positioning bolt 505 is installed at the top of the lifting plate 405. The bottom of component 5 extends into the interior of the rotating groove. Specifically, the rotating base 502 engages with the rotating hole, allowing the positioning frame 501 to rotate around the rotating hole, facilitating angle adjustment of the weeding mechanism 6. A set of locking grooves arranged in a circular array are provided on the outer periphery of the rotating base 502. These locking grooves have an arc structure. A set of locking blocks arranged in a circular array are located on the inner side of the locking sleeve 504, extending into the interior of the locking grooves. Specifically, the locking grooves and locking blocks engage to lock the positioning frame 501 when it rotates to different angles, meeting the needs of multi-angle weeding. To ensure the angular stability of the weeding mechanism 6, the inner side of the lifting plate 405 is provided with two second positioning rods 503. A locking sleeve 504 is installed between the two second positioning rods 503. A sliding hole is opened on each side of the locking sleeve 504, and the second positioning rods 503 pass through the interior of the sliding holes. A retaining ring is installed on one side of the second positioning rod 503, and a support spring is installed on the outer side of the second positioning rod 503. The support spring is located between the retaining ring and the locking sleeve 504. The positioning frame 501, the rotating seat 502, and the second positioning rods 503 are also included. 3. The locking sleeve 504 and the positioning bolt 505 work together to form the angle adjustment mechanism 5. Specifically, the second positioning rod 503 provides a horizontal sliding guide for the locking sleeve 504 and positions the locking sleeve 504 circumferentially; the support spring pushes the locking sleeve 504 closer to the rotating seat 502, realizing the automatic locking of the angle between the locking sleeve 504, the rotating seat 502, and the weeding mechanism 6; after the locking sleeve 504 is stretched outward to compress the spring, the rotating seat 502 is unlocked, which facilitates the angle adjustment of the weeding mechanism 6 and improves the angle adjustment efficiency. In this embodiment, a stabilizing sleeve is provided on one side of the positioning frame 501. A bearing is installed inside the stabilizing sleeve, and a driven shaft 603 is inserted inside the bearing. A support plate 701 is installed at the bottom of the driven shaft 603. A main rotating shaft 602 is installed above the positioning frame 501. A rotating groove is formed at the top of the positioning frame 501, and the bottom of the main rotating shaft 602 extends into the rotating groove. A pulley is installed on the outer side of the main rotating shaft 602 and the driven shaft 603, respectively. A transmission belt is installed between the two pulleys. The second electric motor 601, the main rotating shaft 602, the driven shaft 603, and the weeding blade 604 cooperate to form the weeding mechanism 6. Specifically, the second electric motor 601 drives the main rotating shaft 602 to rotate, which drives the driven shaft 603 to rotate synchronously through the pulleys and the transmission belt, thereby driving the weeding blade. The rotation of blade 604 enables weeding. The rotating groove provides support and positioning for the main rotating shaft 602, preventing it from shaking and ensuring stable power transmission. A positioning block with a rectangular structure is located at the bottom of the rotating shaft 603. A mounting hole corresponding to the positioning block is opened in the middle of the weeding blade 604, and the positioning block extends into the interior of the mounting hole. A set of second locking rods 702 is located above the support plate 701. A set of mounting holes corresponding to the second locking rods 702 is opened in the middle of the weeding blade 604, and the second locking rods 702 pass through the interior of the mounting holes. Specifically, the rectangular positioning block cooperates with the mounting holes to restrict the circumferential rotation of the weeding blade 604, ensuring that the weeding blade 604 rotates synchronously with the rotating shaft 603 and avoiding slippage that affects weeding. The second locking rods 702 pass through the mounting holes to further position the weeding blade 604, ensuring that the weeding blade 604 is securely installed. In this embodiment, a second positioning plate 703 is provided on the outer side of the rotating shaft 603. A sliding groove is formed on each of the two sides of the second positioning plate 703, and a sliding hole is formed on the top of the second locking rod 702. A locking pin 704 is inserted into the locking groove and the sliding hole. There are two locking pins 704, and a connecting plate 705 is installed between the two locking pins 704. The support plate 701, the second locking rod 702, the second positioning plate 703, the locking pins 704, and the connecting plate 705 cooperate to form the locking structure 7. Specifically, the locking pins 704 pass through the sliding groove and the sliding hole to quickly lock the second locking rod 702, preventing the second locking rod from being locked. The loosening of the second locking rod 702 causes the weeding blade 604 to fall off; the connecting plate 705 connects the two locking pins 704, enabling simultaneous unlocking or locking, which is convenient to operate; the locking structure 7 enhances the stability of the weeding blade 604 installation, and the weeding blade 604 can be removed simply by pulling out the locking pins 704, which facilitates the replacement and maintenance of the weeding blade 604. A set of swirling grooves in a circular array are respectively opened at the bottom of the support plate 701 and the second locking rod 702. Specifically, the swirling grooves in the circular array can guide the airflow when the weeding blade 604 rotates, and the airflow can effectively degrade the grass clippings and adhere them to the surface of the weeding blade 604, thereby improving the weeding effect.

[0026] Example 2, based on Example 1, such as Figures 1-6 As shown, a battery or spare tool can be installed inside the storage housing 101 as needed.

[0027] The working principle of this embodiment: Depending on the usage scenario, if it is an outdoor scenario without power, place an adapter battery inside the storage housing 101 and connect the circuit. Observe the flatness of the working ground. If there is a height difference, pull the first locking rod 3 on the side of the support base plate 1 to compress the outer support spring, so that the first locking rod 3 disengages from the locking hole of the stable seat 2; move the stable seat 2 up and down to drive the roller 201 to adjust the height until all four rollers 201 are in stable contact with the ground; release the first locking rod 3, and the support spring pushes the first locking rod 3 to re-insert into the corresponding locking hole to lock the height of the stable seat 2 and the roller 201; Take out the matching weeding blade 604, align the central mounting hole with the rectangular positioning block from the bottom of the rotating shaft 603, and push the weeding blade 604 so that the positioning block is fully embedded in the mounting hole; Then, align the second locking rod 702 on the support plate 701 with the corresponding mounting hole of the weeding knife 604 and insert the second locking rod 702; the locking pin 704 passes through the sliding groove of the connecting plate 705 and the sliding hole at the top of the second locking rod 702, and the two locking pins 704 are connected through the connecting plate 705 to complete the quick double locking of the weeding knife 604. Start the first electric motor 401 to drive the threaded rod 402 to rotate, and the lifting plate 405 rises and falls through the threaded hole in the middle; observe the distance between the weeding blade 604 and the ground, and when the height of the weeding blade 604 is adapted to the height of the weeds to be removed, turn off the first electric motor 401 to complete the height setting; If you need to work in areas such as flower beds or slopes, pull the locking sleeve 504 of the angle adjustment mechanism 5 outward to compress the support spring on the outside of the second positioning rod 503, so that the locking block on the inside of the locking sleeve 504 disengages from the locking groove of the rotating seat 502; hold the positioning frame 501 and rotate the positioning frame 501 around the rotating hole of the lifting plate 405 to drive the weeding mechanism 6 to adjust the angle; after adjustment, release the locking sleeve 504, and the support spring pushes the locking sleeve 504 to reset, completing the angle locking of the weeding mechanism 6; The operator holds the control frame 102 and, after confirming that there are no obstacles in the work area, starts the second electric motor 601. The second electric motor 601 drives the main rotating shaft 602 to rotate, which in turn drives the rotating shaft 603 to rotate synchronously through pulleys and transmission belts, thereby driving the weeding blade 604 to rotate at high speed. Pushing the control frame 102, the weeder moves in the work area via the rollers 201, and the weeding blade 604 contacts the weeds and completes the cutting. The vortex groove at the bottom of the support plate 701 and the second locking rod 702 guides the airflow, reducing the adhesion of grass fragments to the surface of the weeding blade 604 and ensuring weeding efficiency. If weeds of different heights are encountered during operation, the first electric motor 401 can be started at any time to fine-tune the height of the lifting plate 405 to adapt to the changes in weed height; if it is necessary to change the operation scene, repeat the adjustment steps of the weeding mechanism 6 to adjust the angle of the weeding mechanism 6. When replacing the weeding blade 604, pull the locking pin 704 to unlock the weeding blade 604, and then remove the weeding blade 604 for replacement.
