Description

Technical Field

[0001] The invention relates to the technical field of lawn mowers, in particular to a hand-push lawn mower. Background Art

[0002] A lawn mower is also called a weed cutter, a lawn mower, a lawn trimmer, etc. A lawn mower is a mechanical tool used to trim lawns, vegetation, etc. Currently, most hand-push lawn mowers use a rotary blade to cut grass.

[0003] However, if the blade of the existing push lawn mower is damaged, it needs to use a specific tool to disassemble and replace the blade. If the disassembly tool is not carried or there is no disassembly tool outdoors, the blade is damaged and the weeding work cannot be performed again, which seriously affects the weeding efficiency of the lawn mower. Summary of the invention

[0004] The object of the present invention is to provide a push-type lawn mower to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a tool mounting plate, mounting grooves are provided on both sides of the tool mounting plate, a telescopic groove is provided in the middle of the bottom of the tool mounting plate, a first spring is arranged in the telescopic groove, the bottom of the first spring is connected to the telescopic plate, a plurality of connecting plates are connected on both sides of the telescopic plate, a fixed plug rod is arranged on the outer top of the connecting plate; and a vehicle body, a drive box is provided in the middle of the top of the vehicle body, a drive motor is provided in the drive box, a first rotating shaft is plugged into the bottom of the drive motor, and the bottom of the first rotating shaft is connected to the first gear.

[0006] Preferably, rollers are arranged around the bottom of the vehicle body, and a push rod is arranged on one side of the vehicle body, and pushing the push rod can enable the rollers to drive the vehicle body to move.

[0007] Preferably, an entry opening is provided at the front end of the bottom of the vehicle body, and a cutting groove is provided in the middle of the vehicle body, so that grass can enter the cutting groove through the entry opening for cutting and trimming.

[0008] Preferably, second gears are provided on both sides of the bottom of the drive box, and the second gears are located on both sides of the first gear at the bottom of the drive motor and are tightly attached to the first gear. The drive motor can drive the first gear to engage with the second gear by rotating, thereby driving the second gear to rotate.

[0009] Preferably, the bottom of the second gear is connected to the second rotating shaft, the bottom of the second rotating shaft is inserted into the cutting groove opened at the bottom of the vehicle body, the bottom end of the second rotating shaft is connected to the tool mounting plate, and the second gear can drive the tool mounting plate to rotate through the second rotating shaft.

[0010] Preferably, mounting grooves are provided on both sides of the tool mounting plate, in which the tool is clamped, and the tool can cut and trim the grass by rotating the tool mounting plate.

[0011] Preferably, the mounting groove and the top of the tool are provided with multiple groups of plug-in grooves, and the fixed plug rods on the top of the connecting plate correspond one-to-one with the plug-in grooves on the top of the mounting groove and the tool. The first spring can pull the telescopic plate to contract through the contraction force, so that the fixed plug rods on the top of the connecting plate are plugged into the plug-in grooves on the top of the mounting groove and the tool, thereby fixing the tool in the mounting groove.

[0012] Preferably, a contraction groove is opened in the middle of the bottom of the telescopic plate, a second spring is arranged in the contraction groove, the bottom of the second spring is connected to a limit plate, the bottom of the limit plate is connected to a pull rod, and the limit plate can limit the pull rod to prevent the pull rod from falling off from the contraction groove.

[0013] Preferably, the bottom of the pull rod extends out from the contraction groove, and pulling the pull rod can make the pull rod be supported on the bottom inner wall of the contraction groove. Continuing to pull the pull rod can make the pull rod pull the telescopic plate down through the limit plate, so that the fixed plug rod on the top of the connecting plate is disengaged from the installation groove and the plug-in groove opened on the top of the tool, thereby canceling the fixation of the tool.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] The hand-push lawn mower proposed by the present invention, when the tool is damaged, first stops the start, then turns the body over to expose the cutting groove at the bottom of the body, then pulls the pull rod at the bottom of the corresponding damaged tool, so that the pull rod drives the limit plate to be held on the bottom inner wall of the contraction groove, and continues to pull the pull rod, so that the pull rod pulls the telescopic plate through the limit plate, so that the telescopic plate descends in the telescopic groove, and the telescopic plate descends synchronously through the connecting plate while descending, so that the fixed plug rod at the top of the outer side of the connecting plate is disengaged from the top of the installation groove and the plug-in groove opened on the tool, and the fixation of the tool is cancelled. Then the damaged tool is taken out, and a new tool is inserted into the installation groove. Then the pulling rod is released, and the contraction force of the second spring retracts the pull rod into the contraction groove. At the same time, the first spring contracts the telescopic plate into the telescopic groove through the contraction force, and the fixed plug rod at the top of the outer side of the connecting plate is again plugged into the top of the installation groove and the plug-in groove opened on the tool, and the replacement is completed.
