Description

Technical Field

[0001] This utility model relates to the field of grass-pressing technology for lawnmowers, specifically to a grass-pressing structure for a lawnmower and a lawnmower itself. Background Technology

[0002] The main purpose of lawn mowers for compaction is to promote the compactness and flatness of the lawn through mechanical pressure, thereby enhancing its aesthetics. However, how to quickly adjust the height of the compaction plate according to the compaction needs, and how to quickly replace the severely worn compaction plate, are problems that urgently need to be solved.

[0003] A search revealed that CN220173811U discloses a grass-pressing structure for a lawnmower, including a base plate. Two support plates are fixedly installed on one side of the top of the base plate, and a movable block is disposed between the two support plates. A groove is formed on one side of each support plate, and a threaded rod is fixedly installed within the groove. The side end of the movable block is threadedly connected to the threaded rod. A telescopic column is fixedly installed on one side of the movable block, and a spring is sleeved on the outer side of the telescopic column. An arc-shaped pressure plate is fixedly installed on one side of the telescopic column, and the spring is fixedly connected to the arc-shaped pressure plate. Rollers are rotatably installed at the four corners of the bottom of the base plate. This lawnmower grass-pressing structure is simple in structure, easy to use, has strong connectivity, and facilitates adjustment of the grass-pressing plate height, enhancing its practicality.

[0004] The grass-pressing structure of the above-mentioned lawnmower has an arc-shaped pressure plate on one side of the base plate for pressing grass, and the height of the arc-shaped pressure plate can be adjusted by manually turning the No. 1 threaded rod.

[0005] The design flaw is that when the device faces grass bundles of varying heights within an area, it requires frequent turning of the No. 1 threaded rod to adjust the height of the curved pressure plate. This is not only time-consuming and labor-intensive, but the lawnmower also cannot manually adjust the height of the curved pressure plate while moving, resulting in low grass-pressing efficiency. Furthermore, the curved pressure plate is prone to wear when in contact with hard objects such as stones on the ground, and the design cannot quickly replace the severely worn curved pressure plate. Utility Model Content

[0006] This utility model proposes a grass-pressing structure for a lawnmower and a lawnmower in general, which solves the problems of existing technologies that make it difficult to adjust the height of the curved pressing plate, and also make it impossible to quickly adjust the height of the curved pressing plate during operation; as well as the inability to quickly disassemble and replace the severely worn curved pressing plate.

[0007] The technical solution of this utility model is as follows: a grass-pressing structure for a lawnmower, including a lifting assembly, wherein the lifting assembly includes two sets of symmetrically arranged synchronous rods;

[0008] Threaded rings distributed on the lower outer side of each of the aforementioned synchronizing rods and having the same direction;

[0009] A lifting mounting plate that is threadedly connected to the synchronizing rod at the threaded ring and can move up and down synchronously with the synchronizing rod as it rotates.

[0010] A straw-pressing component installed on the side of the lifting mounting plate for performing the straw-pressing process and capable of being quickly disassembled and replaced on the side of the lifting mounting plate;

[0011] The grass-pressing assembly includes a grass-pressing plate;

[0012] Symmetrically fixed rods are attached to the inner side of the straw pressing board;

[0013] A slot is formed on the side of the insert.

[0014] Preferably, the lifting assembly further includes:

[0015] A forward and reverse motor is fixedly installed at the bottom of one of the sets of synchronizing rods;

[0016] The output terminals of the forward and reverse motors are fixedly connected to the set of synchronization rods.

[0017] Preferably, the lifting assembly further includes:

[0018] A timing pulley fixedly connected to the upper outer side of each of the timing rods;

[0019] A timing belt fitted over the outside of the two sets of timing pulleys;

[0020] The inner side of the synchronous belt is in contact with two sets of synchronous pulleys and is connected by meshing transmission.

[0021] Preferably, the lifting assembly further includes:

[0022] Symmetrical rails are cut throughout the entire body of the lifting mounting plate.

[0023] Preferably, the lifting assembly further includes:

[0024] An inner tube fixedly connected inside each of the aforementioned rail grooves;

[0025] A sliding rod is slidably connected to the inside of the inner tube;

[0026] The slide bar is matched to the slot size.

[0027] Preferably, the lifting assembly further includes:

[0028] A sleeve fixedly connected to the outside of the inner tube;

[0029] A handle is fixedly connected to the top of the socket.

[0030] Preferably, the lifting assembly further includes:

[0031] A spring coil fitted onto the outside of the inner tube;

[0032] One end of the spring coil is fixedly connected to the inner tube;

[0033] The other end of the spring coil is fixedly connected to the sleeve.

[0034] Preferably, the lawnmower assembly includes a lawnmower body;

[0035] And a rotating mowing mechanism fixedly installed in the middle of the mower body.

[0036] Preferably, the lawnmower assembly further includes:

[0037] Rotate the casters that are connected to the bottom of the lawnmower body.

[0038] Preferably, the lawnmower assembly further includes:

[0039] A handle is symmetrically and fixedly connected to one side of the top of the lawnmower body;

[0040] An anti-slip sleeve is fitted onto the upper outer side of the grip.

[0041] The beneficial effects of this utility model are as follows:

[0042] This invention features a sliding rod located at the track groove on the lifting mounting plate. By holding the handle and using the sleeve, the sliding rod is pushed towards the inner tube. After the grass pressing plate is inserted into the slot on the side of the lifting mounting plate through the insertion rod, releasing the handle allows the sliding rod to return to its original position under the elastic action of the spring ring, thus allowing the sliding rod to be inserted into the slot. This design allows for quick disassembly and replacement of severely worn grass pressing plates. Simultaneously, starting the forward and reverse motors, and with the action of the synchronous pulley and synchronous belt, causes the two sets of synchronous rods to rotate synchronously. This allows the lifting mounting plate, which is threadedly connected to the synchronous rod at the threaded ring, to drive the grass pressing plate to rise and fall synchronously. This design allows for rapid adjustment of the grass pressing plate height during the movement of the lawnmower assembly, thus adapting to different grass pressing height requirements.
