Description

Technical Field

[0001] This utility model relates to the field of lawnmower technology, specifically to a lawnmower blade assembly that allows for convenient and quick blade replacement. Background Technology

[0002] In order to better manage the weeds on the green space, staff need to walk on the green space with handheld lawnmowers to harvest the weeds. The blade assembly is an important part of the lawnmower. When mowing, the drive assembly drives the blade assembly to rotate quickly to clear the weeds.

[0003] Chinese utility model patent CN216492030U discloses a lawnmower and its blade assembly and cutting device. The blade assembly includes a blade, a positioning member, and blades. The blade has a disc surface, the positioning member is disposed on the disc surface, and the blades are straight and connected to the positioning member. The blades are used to rotate around the normal of the disc surface. The blades have through grooves, and one end of the positioning member facing away from the disc surface is disposed in the through groove and can slide along the length of the through groove. At least two edges of the blades have cutting edges. The beneficial effect of this embodiment is that by improving the blade structure and utilizing the multi-edged characteristic of the blade, and through the through groove, the blade moves rapidly along the direction of the through groove while rotating, thereby enabling rapid blade rotation, improving cutting efficiency, preventing premature dulling caused by only one edge being continuously used, slowing down the dulling rate, and extending the service life of the blade assembly.

[0004] Based on existing solutions and actual production and processing, in the existing lawnmower blade assembly, each mowing blade needs to be fixed to the blade assembly with screws. When it is necessary to remove all the mowing blades, each blade needs to be removed one by one, which is inconvenient for quickly replacing all the mowing blades. Therefore, we propose a lawnmower blade assembly that allows for quick and easy blade replacement to solve the problems mentioned above. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a lawnmower blade assembly for convenient and quick blade replacement, comprising a mounting plate, a blade assembly disposed below the mounting plate, and lawnmower blades mounted at the bottom of the blade assembly.

[0007] The mounting plate has a shaft hole in the middle, a base plate is provided below the cutter head, an arc plate is fixed to the side of the mounting plate, a cleaning frame is installed below the arc plate, a combing rod is fixed at an equal angle to the outer end of the arc plate, and a cleaning component is provided on the outer side of the combing rod.

[0008] Preferably, the mowing blades are mounted at equal angles at the bottom of the blade disc, and the mowing blades are fixedly connected to the blade disc by a base plate and screws.

[0009] Preferably, the base plate and the mowing blade are connected by a snap-fit ​​connection.

[0010] Preferably, the cleaning frame is fixedly connected to the arc-shaped plate by screws.

[0011] Preferably, the cleaning assembly includes a ring, an arc-shaped connecting rod, and a rubber plate. The arc-shaped connecting rod is fixed to the outer side of the ring, and the rubber plate is fixed to the side of the ring.

[0012] Preferably, a combing rod runs through the interior of the arc-shaped connecting rod.

[0013] Preferably, the rubber sheet has holes inside that connect to the arc-shaped plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are: the lawnmower blade assembly that facilitates quick blade replacement makes it easy to quickly disassemble and assemble the mowing blades, and the cleaning assembly can quickly clean the grass wrapped around the comb bar, thus preventing the space between the blade and the mowing blade from being blocked.

[0015] 1. The mowing blades are fixed to the blade head by the base plate and screws. By removing the screws connecting the base plate and the blade head, all the mowing blades can be removed, which makes it easy to quickly disassemble and assemble the mowing blades.

[0016] 2. The grass is pre-combed by the combing rods set at equal intervals. The cleaning component can quickly clean the grass wrapped around the combing rods. Remove the rubber plate from the arc plate, and then move the ring and arc connecting rod downwards. The grass wrapped around the combing rods will leave the combing rods.

[0017] 3. The lower surface of the cleaning frame is in contact with the upper surface of the mowing blade. During the mowing process, the cleaning frame clears the space between the mowing blade and the blade disc, which can prevent the space between the blade and the blade from being blocked.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Example: Please refer to Figures 1-7 In existing lawnmower blade assemblies, each blade 3 needs to be fixedly connected to the blade 2 with screws. When all the blades 3 need to be removed, they need to be removed one by one, which is inconvenient for quickly replacing all the blades 3. In order to solve this technical problem, this embodiment discloses the following technical content.

[0028] A lawnmower blade assembly with convenient and quick blade replacement includes a mounting plate 1, a blade 2 disposed below the mounting plate 1, and a mowing blade 3 mounted on the bottom end of the blade 2. A shaft hole is provided in the middle of the mounting plate 1, and a base plate 4 is disposed below the blade 2. The mowing blade 3 is mounted at an equal angle on the bottom end of the blade 2. The mowing blade 3 is fixedly connected to the blade 2 by the base plate 4 and screws. The connection between the base plate 4 and the mowing blade 3 is a snap-fit ​​connection.

[0029] When it is necessary to remove all the mowing blades 3, remove the screws that connect the base plate 4 and the mounting plate 1, then separate the base plate 4 from the mowing blades 3, and you can remove all the mowing blades 3. Quickly disassemble and assemble the mowing blades 3.

[0030] When it is necessary to install the mowing blade 3, place the mowing blade 3 at the bottom of the blade disc 2, then align the base plate 4 with the blade disc 2, and the base plate 4 and the mowing blade 3 are engaged and connected. Then, fix the base plate 4 to the blade disc 2 with screws to quickly install all the mowing blades 3.

[0031] An arc-shaped plate 5 is fixed to the side of the mounting plate 1. A cleaning frame 6 is installed below the arc-shaped plate 5. The lower surface of the cleaning frame 6 is in contact with the upper surface of the mowing blade 3. When the mowing blade 3 rotates, the mowing blade 3 is cleaned by the cleaning frame 6. The cleaning frame 6 is fixedly connected to the arc-shaped plate 5 by screws, making it easy to disassemble and assemble the cleaning frame 6 and the arc-shaped plate 5.

[0032] During the movement of the lawnmower, the grass is combed by the combing rods 7 set at equal angles.
