Description

Technical Field

[0001] This utility model relates to the field of lawn mowers, specifically a new type of agricultural lawn mower. Background Technology

[0002] Agricultural lawnmowers are mechanical devices used in agricultural settings such as farmland, pastures, and orchards to trim vegetation and remove weeds. Their core function is to improve operational efficiency, reduce labor costs, and promote the healthy growth of crops. There are many types of agricultural lawnmowers available, including rotary lawnmowers, reciprocating lawnmowers, overhead lawnmowers, ride-on lawnmowers, and handheld lawnmowers.

[0003] Existing handheld electric lawnmowers are typically handheld, compact, and lightweight. They generally consist of a handle, motor, and blades, and have a relatively simple structure. They are suitable for mowing large lawns in parks, golf courses, football fields, and other similar locations, enabling them to complete mowing tasks quickly and efficiently. In farmland, they can be used to remove weeds, creating a better environment for crop growth. For wasteland or land overgrown with weeds, handheld electric lawnmowers, with their powerful motors and wide mowing width, can quickly clear weeds, preparing the land for subsequent reclamation and planting.

[0004] However, farmland is not all flat terrain. When using a handheld electric lawnmower, users try to keep the blades close to the ground and relatively parallel to it. However, when working on uneven ground, the high-speed rotating blades may collide with the sloping ground, which can cause safety risks and damage the blades, making safe operation difficult. In addition, existing handheld electric lawnmowers have poor protective performance and lack protective structures for the blades. When the blades are cutting grass close to the ground, they may also come into contact with large stones, which can also pose a safety risk. Utility Model Content

[0005] The purpose of this utility model is to provide a new type of agricultural lawn mower in order to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel agricultural lawn mower, comprising a mounting base, a motor mounted on the upper end of the mounting base, a blade provided at the output end of the motor, and a main rod rotatably connected to one end of the mounting base via a shaft; An adjustment component is provided between the main rod and the mounting base to adjust the relative rotation angle between the mounting base and the main rod, so that the cutter remains relatively parallel to the ground in different terrains.

[0007] As a further embodiment of this utility model: the adjustment assembly includes a fixed seat fixed on the outer wall of the middle part of the main rod, one end of the fixed seat is connected to a screw, the end of the screw near the mounting seat is circumferentially connected to a first connecting rod, and a second connecting rod is connected between the first connecting rod and the mounting seat.

[0008] As a further improvement of this utility model: the screw and the fixed seat are connected by a thread, and the end of the fixed seat away from the mounting seat is connected to a handle.

[0009] As a further embodiment of this utility model: the two ends of the second connecting rod are respectively rotatably connected to the mounting base and the first connecting rod via shafts.

[0010] As a further improvement of this utility model, a protective component is fixedly connected to the periphery of the mounting base to protect the periphery of the blade and prevent large stones on the ground from contacting the blade.

[0011] As a further embodiment of this utility model: the protective component includes a protective cover, which is fixed to the periphery of the mounting base by bolts, and the protective cover is located directly above the cutting tool. The outer wall of the end of the protective cover away from the main rod is surrounded by a plurality of equally spaced baffles.

[0012] As a further improvement of this utility model: the baffle has an "L"-shaped thin sheet structure, and multiple baffles are distributed in a semi-circular array.

[0013] Compared with the prior art, the beneficial effects of this utility model are: This invention features an adjustment component between the mounting base and the main rod, which allows for adjustment of the relative rotation angle between them. This enables the blades to be kept relatively parallel to the terrain or slope, adapting to dust removal operations on different terrains and improving the performance of the lawnmower. It also effectively reduces the likelihood of damage caused by blades contacting the ground. Furthermore, a protective component is added around the mounting base to prevent the blades from contacting large stones without hindering contact between the blades and weeds.

[0016] 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.

[0017] Please see Figures 1-4 In this embodiment of the utility model, a novel agricultural lawn mower includes a mounting base 1, a motor 2 mounted on the upper end of the mounting base 1, a blade 3 provided at the output end of the motor 2, and a main rod 5 rotatably connected to one end of the mounting base 1 via a shaft. An adjustment component 6 is provided between the main rod 5 and the mounting base 1 to adjust the relative rotation angle between the mounting base 1 and the main rod 5 so that the cutter 3 remains relatively parallel to the ground in different terrains; Adjustment component 6 includes a fixing seat 601 fixed on the outer wall of the middle part of the main rod 5. One end of the fixing seat 601 is connected to a screw 602. The end of the screw 602 near the mounting seat 1 is circumferentially connected to a first connecting rod 603. A second connecting rod 604 is connected between the first connecting rod 603 and the mounting seat 1. The screw 602 is connected to the fixed seat 601 by a thread, and the fixed seat 601 is connected to a handle at the end away from the mounting seat 1.

[0018] The two ends of the second connecting rod 604 are rotatably connected to the mounting base 1 and the first connecting rod 603 respectively via shafts.

[0019] In this embodiment: Since farmland is not always flat, when using a handheld electric lawnmower, the user tries to keep the blades close to the ground and relatively parallel to it. However, when working on uneven ground, the high-speed rotating blades may collide with the sloping ground, posing a safety risk and damaging the blades, which is detrimental to safe operation. Therefore, this solution provides an adjustment component 6 between the mounting base 1 and the main rod 5. This component can be used to adjust the relative rotation angle between the mounting base 1 and the main rod 5, so as to adjust the blades 3 to maintain relative parallelism with the terrain slope according to different terrains or slopes. This adapts to dust removal operations on different terrains, improves the performance of the lawnmower, and effectively reduces the probability of damage caused by the blades 3 contacting the ground.

[0020] Specifically, in order to facilitate use in different terrains, the lawnmower in this solution has a rotating connection between the mounting base 1 and the main rod 5 via a shaft. By adding an adjustment component 6 between the mounting base 1 and the main rod 5, the relative rotation angle between the mounting base 1 and the main rod 5 can be adjusted. Thus, without changing the normal holding posture, the user can adjust the relative tilt angle of the blade 3 according to the terrain, which greatly reduces the risk of the blade 3 contacting the ground and also extends the service life of the blade 3. When it is necessary to adjust the tilt angle of the cutter 3, that is, to adjust the relative rotation angle between the motor 2 and the main rod 5, simply turn the screw 602. The screw 602 will push or pull the adjustment component 6 forward or backward, which will force the mounting base 1 and the main rod 5 to rotate relative to each other, thereby changing the tilt angle of the cutter 3. The tilt angle of the cutter 3 can be adjusted according to the ground terrain. The operation is convenient and the adjustment is quick. After adjustment, it can also effectively maintain the relative rotation angle between the mounting base 1 and the main rod 5.

[0021] It should be noted that the rotation direction of the screw 602 and the first connecting rod 603 in this scheme is different from the rotation direction between the second connecting rod 604 and the first connecting rod 603. The rotation direction of the screw 602 and the first connecting rod 603 is based on the circumferential direction of the screw 602. This is mainly to avoid hindering the connection between the screw 602 and the first connecting rod 603 when the screw 602 is turned.

[0022] Please refer to this carefully. Figures 1-4 The mounting base 1 is fixedly connected to a protective component 4, which is used to cover and protect the outer periphery of the tool 3 to prevent large stones on the ground from contacting the tool 3. The protective component 4 includes a protective cover 401, which is fixed to the periphery of the mounting base 1 by bolts and is located directly above the cutter 3. The outer wall of the end of the protective cover 401 away from the main rod 5 is surrounded by a plurality of equally spaced baffles 402. The baffle 402 has an "L"-shaped thin sheet structure, and multiple baffles 402 are distributed in a semi-circular array.

[0023] In this embodiment: Because existing handheld electric lawnmowers have poor protective performance and lack protective structures for the blades, the blades are likely to come into contact with large stones while cutting grass close to the ground, thus posing a safety risk. Therefore, this solution adds a protective component 4 to the periphery of the mounting base 1. The protective component 4 mainly includes a protective cover 401 and baffles 402, which are combined to form a circular cover structure. There are multiple protective covers 401, which are arranged in a semi-circular ring structure. This design can prevent the blades 3 from coming into contact with large stones. Since weeds are long and thin, most of the weeds will not be obstructed during the movement of the blades 3, and will be located between two adjacent baffles 402. In this way, the blades 3 can come into contact with the weeds located between two adjacent baffles 402 and cut them.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
