Description
Technical Field
[0001] The invention relates to the technical field of gardening and pruning, in particular to a novel gardening and pruning edge trimmer. Background Art
[0002] The trimmer used for landscaping is a common garden machine. Usually, a handle is set in the structure. When in use, it is operated by the handle to trim the lawn and low shrubs to make the plants more beautiful. In some garden landscapes, the trimmer can also be used to shape the plants to give them a unique shape for viewing. The lawn needs to be trimmed during maintenance. The lawn mower can be used to trim the middle of the lawn, but the path in the middle of the lawn is easily covered by the grass on the edge of the lawn. Since the lawn ground is lower than the road surface of the path, in order to prevent the lawn mower's blade from damaging the curb and the blade itself from being damaged, the lawn mower cannot trim the lawn edge.
[0003] At present, most of the existing lawn trimmers are manually carried, and the grass stems are broken by driving a high-speed rotating nylon rope. Even if it hits the curb, it will not cause damage. However, this type of lawn trimmer requires the shoulders and arms of the workers to bear the weight of the trimmer, and the height can only be controlled manually by the workers. After the trimming work is completed, the trimmed grass will be left on the road surface and needs to be cleaned again, which increases the workload. Summary of the invention

After the speed is reduced by the gear set 400, the driving pulley 403 is driven to rotate. After the driving belt 404 drives the reduction pulley 405 to rotate, the driving wheel 408 is used to drive the entire trimmer to move forward.
[0024] like Figure 3-Figure 5 as well as Figure 8 As shown, an electromagnetic clutch 801 is provided on the side of the reduction box 402 away from the driving motor 401, the output shaft end of the driving motor 401 is dynamically connected to the input shaft of the electromagnetic clutch 801, the output shaft key of the electromagnetic clutch 801 is connected to the intermediate pulley 802, and an increasing gear box 804 is embedded inside the base 1, and the input shaft key of the increasing gear box 804 is connected to the increasing pulley 805 connected to the intermediate pulley 802 through the intermediate belt 803.
[0025] like Figure 6-Figure 9As shown, the trimming mechanism 5 includes a bolt plate 501 installed on the side of the base 1, the bottom of the bolt plate 501 is set as a track frame 502, the inner sliding of the track frame 502 is provided with an arc block 505, the middle of the arc block 505 is connected with a rotating shaft through a bearing, and the two ends of the rotating shaft are respectively provided with a trimming wheel 506 and a pinion 507, the circumference of the trimming wheel 506 is provided with a nylon rope 509, and the bottom of the speed increasing gear box 804 is connected with a speed increasing gear 508 meshing with the pinion 507 through an output shaft key.
[0026] During specific use, the electromagnetic clutch 801 is controlled to be turned on through the switch panel 2, and the power of the drive motor 401 is directly transmitted to the intermediate pulley 802. The intermediate pulley 802 drives the speed-increasing pulley 805 to rotate through the intermediate belt 803, thereby rotating the gears inside the speed-increasing gearbox 804. After the speed is increased by the speed-increasing gearbox 804, the output shaft is used to rotate the speed-increasing gear 508. After the speed is increased again through the cooperation of the pinion 507 and the speed-increasing gear 508, the trimming wheel 506 is directly driven to rotate at high speed, and the edge of the lawn is trimmed by the swing of the nylon rope 509. The trimmed grass clippings are scattered and fall, and some of the grass clippings fall on the road surface under the trimmer.
[0027] like Fig. 9 and Fig.10 As shown, the outer wall of the track frame 502 is provided with an arc groove 504, the middle part of the arc block 505 is provided with a spring tube 511 inserted into the arc groove 504, the inside of the spring tube 511 is movably provided with a spring column 512, a compression spring 513 is provided between the spring column 512 and the spring tube 511, the movable end of the spring column 512 is provided with a pull ring 510, and the outer side of the arc groove 504 is provided with an anti-slip plate 503 to prevent the pull ring 510 from sliding.
[0028] During specific use, the compression spring 513 is compressed shorter by pulling the pull ring 510. At this time, the compression spring 513 leaves the anti-slip plate 503, so that the arc block 505 can be easily moved. After the arc block 505 is adjusted to a suitable height inside the track frame 502, the pull ring 510 is released and the elastic force of the compression spring 513 is used to press the pull ring 510 against the anti-slip plate 503 to prevent the arc block 505 with the adjusted height from moving, thereby achieving the purpose of facilitating the adjustment of the trimming height.
[0029] like Figure 7 and Fig.12 As shown, the suction mechanism 7 includes a dust collection cylinder 704 at the bottom of the base 1 and a collection box 701 at the top of the base 1. The bottom of the dust collection cylinder 704 is detachably connected to a cutting net 700 via bolts, and the inner wall of the dust collection cylinder 704 is movably connected to a suction fan 712 via a bearing frame 711.
[0030] like Figure 7-Figure 8As shown, the top key of the suction fan 712 is connected to the fan pulley 707, and the other side of the speed increasing gear box 804 is connected to the high-speed pulley 710 through the output shaft key. The fan pulley 707 and the high-speed pulley 710 are connected by a transmission belt 709. The transmission belt 709, the fan pulley 707, and the high-speed pulley 710 are arranged inside the belt box 708 at the bottom of the base 1.
[0031] like Fig.12 As shown, a connection port 713 connecting the collection box 701 and the dust collection cylinder 704 is provided in the middle of the base 1 , and a cover plate 702 is movably connected to the top of the collection box 701 through a hinge, and a handle 703 is provided on the rear side of the top of the cover plate 702 .
[0032] During specific use, after the power is transmitted to the speed-increasing gearbox 804 through the driving motor 401, the output shaft of the speed-increasing gearbox 804 drives the high-speed pulley 710 to rotate, and then the transmission belt 709 drives the fan pulley 707 to rotate, so that the suction fan 712 rotates at high speed to suck the air below the suction fan 712 to the top, and at the same time, the cut grass clippings on the road surface are also sucked upward into the dust collection cylinder 704, and then the sucked grass clippings follow the flowing air from the connection port 713 into the collection box 701, and the grass clippings are collected. When a certain amount of grass clippings needs to be cleaned, the cover 702 is opened using the handle 703 to clean the inside of the collection box 701.
[0033] like Fig.12 As shown, two air outlets 705 are symmetrically arranged on the rear side of the collection box 701, an isolation net 714 is arranged at the connection between the air outlet 705 and the collection box 701, the middle of the air outlet 705 passes through the base 1, and the bottom of the air outlet 705 is provided with a blowing nozzle 706 inclined toward the bottom of the dust collection tube 704.
[0034] During specific use, as the air inside the dust collector 704 enters the collection box 701 from the connection port 713, the air pressure inside the collection box 701 increases, and the air is discharged from the air outlet 705 after being filtered by the isolation net 714. The air is blown obliquely downward to the bottom of the dust collector 704 through the air nozzle 706 below the air outlet 705. Fine dust and grass clippings on the road surface will be embedded in the small pit. The oblique downward blowing airflow will blow up the fine grass clippings on the road surface that have not been sucked up by the dust collector 704, and then follow the airflow to enter the bottom of the dust collector 704, so that they can be sucked into the dust collector 704 and collected into the collection box 701, thereby further achieving the purpose of cleaning up the grass clippings.
[0035] like Fig.11 and Fig.13As shown, a bevel gear box 603 is arranged in the middle of the driving shaft 406, an intermediate shaft cylinder 604 is arranged on one side of the bevel gear box 603, and an intermediate gear box 600 is arranged at the other end of the intermediate shaft cylinder 604. Two driving bevel gears 608 are symmetrically arranged inside the intermediate gear box 600, and the two driving bevel gears 608 are symmetrically meshed with side bevel gears 607 on the outside, and universal joint cylinders 605 are arranged on the left and right sides of the intermediate gear box 600. The tops of the intermediate gear box 600 and the bevel gear box 603 are fixedly connected to the bottom wall of the base 1.
[0036] Two wheel plates 602 are symmetrically arranged on the left and right sides of the bottom of the base 1. The bottom of the wheel plate 602 is movably connected to a cleaning wheel 601 through a bearing. The interior of the universal joint cylinder 605 is provided with a ball cage universal joint 606 that connects and drives the cleaning wheel 601 and the side bevel gear 607.
[0037] like Fig.13 As shown, the top of the wheel plate 602 is slidably arranged in a slide groove 614 opened at the bottom of the base 1 , and the middle parts of the two wheel plates 602 are hinged to the top of the same T-bar 612 through two push-pull rods 613 .
[0038] like Figure 13-Figure 15 As shown, a push-pull groove 610 is provided on the side wall of the dust collection cylinder 704, and a reciprocating cylinder 611 is movably provided inside the push-pull groove 610. A reciprocating screw 609 coaxially rotating with the driving bevel gear 608 is provided inside the reciprocating cylinder 611. The top of the reciprocating cylinder 611 is fixedly connected to the bottom of the T-bar 612. A connecting rod 617 is provided at one end of the reciprocating cylinder 611 located inside the dust collection cylinder 704, and a knife frame 616 is provided at the bottom of the connecting rod 617. Sharp knives 615 inserted into the gaps in the cutting net 700 are evenly spaced at the bottom of the knife frame 616.
[0039] During specific use, while the driving motor 401 drives the driving shaft 406 to rotate, since a bevel gear box 603 is provided in the middle of the driving shaft 406, the two bevel gears provided inside the bevel gear box 603 mesh with each other, so that the power is transmitted to the rotating shaft inside the intermediate shaft tube 604, thereby driving the driving bevel gear 608 to rotate, and then the two driving bevel gears 608 are used to drive the side bevel gears 607 on both sides to rotate, and the two cleaning wheels 601 are rotated at the same time through the transmission of the ball cage universal joint 606. The edge of the cleaning wheel 601 is tilted forward, so that the cleaning wheel 601 can more easily sweep the grass clippings on the road surface to the bottom of the dust collection cylinder 704. After sweeping the grass clippings on the road surface, it is easier for the grass clippings to be sucked into the dust collection cylinder 704. At the same time, when the driving bevel gear 608 rotates, the reciprocating screw 609 can be rotated, and the reciprocating cylinder 611 is driven to move back and forth through the rotation of the reciprocating screw 609. Fig.14 and Fig.15As shown, the connecting rod 617 is used to drive the sharp knife 615 at the bottom of the knife frame 616 to reciprocate inside the cutting net 700. When longer grass blades pass through the cutting net 700, they can be cut by the sharp knife 615 to prevent the grass blades from being too long and getting entangled inside the trimmer. At the same time, when the reciprocating cylinder 611 reciprocates, it can drive the T-bar 612 to move, and the push-pull rod 613 hinged on the top of the T-bar 612 drives the wheel plate 602 to move in the slide groove 614. Since both ends of the push-pull rod 613 are hinged, it can adapt to the movement of the wheel plate 602 in the arc-shaped slide groove 614, so that the cleaning wheel 601 can rotate around the ball cage universal joint 606, so that the cleaning wheel 601 can drive the cleaning wheel 601 to rotate normally when the angle is changed, so that the end of the cleaning wheel 601 can normally clean the ground when reciprocating, and the cleaning effect is improved by reciprocating the cleaning wheel 601.
[0040] The specific use steps and principles of the present invention are as follows: First, the drive motor 401 is turned on through the switch panel 2, and the speed of the drive motor 401 is set through the switch panel 2. When the edge trimmer is moved to the edge of the lawn, the speed is reduced through the gear set 400 inside the reduction box 402, and finally the drive pulley 403 is driven to rotate. After the drive belt 404 drives the reduction pulley 405 to rotate, the drive shaft 406 drives the two drive wheels 408 to rotate at the same time, and the drive wheels 408 drive the entire edge trimmer to move forward; When the lawn edge needs to be trimmed, the trimming mechanism 5 is adjusted according to the height of the lawn, and the compression spring 513 is compressed shorter by pulling the pull ring 510. At this time, the compression spring 513 leaves the anti-slip plate 503, so that the arc block 505 can be easily moved. After the arc block 505 is adjusted to a suitable height inside the track frame 502, the pull ring 510 is released and pressed against the anti-slip plate 503 under the elastic force of the compression spring 513 to prevent the arc block 505 with the adjusted height from moving, thereby achieving the purpose of facilitating the adjustment of the trimming height. Afterwards, the electromagnetic clutch 801 is controlled to be turned on through the switch panel 2, and the drive motor 401 is adjusted to a suitable speed. While the drive motor 401 drives the drive wheel 408 and the sweeping wheel 601 to rotate, the power can also be transmitted to the intermediate pulley 802 through the electromagnetic clutch 801, so that the intermediate pulley 802 drives the speed-increasing pulley 805 to rotate through the intermediate belt 803, thereby rotating the gear inside the speed-increasing gear box 804. After the speed is increased by the speed-increasing gear box 804, the speed-increasing gear 508 is rotated by the output shaft. After the speed is increased again by the cooperation of the pinion 507 and the speed-increasing gear 508, the trimming wheel 506 is directly driven to rotate at a high speed, and the edge of the lawn is trimmed by the swing of the nylon rope 509. The trimmed grass clippings are scattered and fall, and some of the grass clippings fall on the road surface below the trimmer. While the driving motor 401 drives the driving shaft 406 to rotate, since the bevel gear box 603 is provided in the middle of the driving shaft 406, the two bevel gears provided inside the bevel gear box 603 mesh with each other, so that the power is transmitted to the rotating shaft inside the intermediate shaft tube 604, thereby driving the driving bevel gear 608 to rotate, and then the two driving bevel gears 608 drive the side bevel gears 607 on both sides to rotate, and through the transmission of the ball cage universal joint 606, the two cleaning wheels 601 rotate at the same time, and the edges of the cleaning wheels 601 are tilted forward, so that the cleaning wheels 601 can more easily sweep the grass clippings on the road surface to the bottom of the dust collection cylinder 704, and after sweeping the grass clippings on the road surface, it is easier for the grass clippings to be sucked into the dust collection cylinder 704; At the same time, after the driving motor 401 transmits the power to the speed increasing gear box 804, the output shaft of the speed increasing gear box 804 drives the high speed pulley 710 to rotate, and then the transmission belt 709 drives the fan pulley 707 to rotate, so that the suction fan 712 rotates at a high speed to suck the air below the suction fan 712 upward, and at the same time, the grass clippings cut on the road surface are sucked upward into the dust collecting cylinder 704, and then the sucked grass clippings follow the flowing air from the connection port 713 into the interior of the collection box 701, and the grass clippings are collected; At the same time, when the bevel gear 608 is driven to rotate, the reciprocating screw 609 can be rotated, and the reciprocating cylinder 611 can be driven to move back and forth by the rotation of the reciprocating screw 609. Fig.14 and Fig.15As shown, the connecting rod 617 is used to drive the sharp knife 615 at the bottom of the knife frame 616 to reciprocate inside the cutting net 700. When a longer grass blade passes through the cutting net 700, it can be cut by the sharp knife 615 to prevent the grass blade from being too long and entangled inside the trimmer. At the same time, when the reciprocating cylinder 611 reciprocates, it can drive the T-bar 612 to move, and the push-pull rod 613 hinged at the top of the T-bar 612 drives the wheel plate 602 to move in the slide groove 614. Since both ends of the push-pull rod 613 are hinged, it can adapt to the movement of the wheel plate 602 in the arc-shaped slide groove 614, so that the cleaning wheel 601 can rotate around the ball cage universal joint 606, so that the cleaning wheel 601 can be driven to rotate normally when the angle is changed, so that the end of the cleaning wheel 601 can normally clean the ground when reciprocating, and the reciprocating cleaning wheel 601 improves the cleaning effect; As the air inside the dust collection cylinder 704 enters the collection box 701 from the connection port 713, the air pressure inside the collection box 701 increases, and the air is discharged from the air outlet cylinder 705 after being filtered by the isolation net 714, and the air is blown obliquely downward to the bottom of the dust collection cylinder 704 through the air blowing nozzle 706 below the air outlet cylinder 705, and fine dust and grass clippings on the road surface will be embedded in the small pit. The oblique downward blowing airflow will make the fine grass clippings on the road surface that have not been sucked up by the dust collection cylinder 704 be blown up, and then follow the airflow to enter the bottom of the dust collection cylinder 704, so that they can be sucked into the dust collection cylinder 704 and collected into the collection box 701, thereby further achieving the purpose of cleaning up the grass clippings; Finally, when a certain amount of waste is collected and needs to be cleaned, the cover 702 can be opened using the handle 703 to clean the inside of the collection box 701.
