Description

Technical Field

[0001] The present invention relates to the technical field of lawn mowers, and specifically to a new type of handheld lawn mower. Background Art

[0002] A handheld lawn mower is a portable mechanized tool widely used in agricultural and landscaping operations. It can replace manual labor to quickly trim lawns, green belts, etc., effectively saving manpower. However, there are still many inconveniences in the current use of handheld lawn mowers, resulting in limited actual use efficiency. Therefore, in order to make the handheld lawn mower more efficiently applied to the fields of agriculture and garden maintenance, a new type of handheld lawn mower is specifically proposed.

[0003] After retrieval, a patent with the publication number CN219577840U discloses a handheld lawn mower, belonging to the technical field of lawn mowers, including a device housing, and both sides of the inner wall of the device housing are rotatably connected with connecting rods.

[0004] The following defects still exist in the prior art during use: The handheld lawn mower in the prior art needs to be pushed by manpower during actual use, and the user needs to continuously apply a pulling force to suspend the lawn mower at a certain distance from the ground. As a result, the load on the user's arms is relatively large during the work process. And since the mowing effect is completely determined by manual operation, it is easy to cause the situation where the trimming lengths of the lawn are not uniform, which not only consumes a large amount of manpower but also affects the actual mowing effect. The handheld lawn mower in the prior art uses a splash guard as a protective structure to block the flying grass and shrub branches during the mowing process. Due to the protective effect of the splash guard, the cut grass and shrub branches will move towards the cutter or cutting blade under the guidance of the splash guard, and then after secondary cutting or acceleration, continuous collisions will occur inside the splash guard, thus increasing the failure rate during the equipment operation process and there is also a certain safety risk.

[0005] In view of this, we propose a new type of handheld lawn mower to solve the existing problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a new type of handheld lawn mower to solve the problems raised in the above background art.

The right side of the installation shell is rotatably connected to one end of an electric telescopic push rod. At the bottom inside the installation shell, there is a motor fixedly installed. The output shaft of the motor extends to the bottom of the installation shell and is equipped with a turntable. At the bottom of the installation shell, there is a support disk rotatably installed, and on the side of the support disk, there are blades installed at equal intervals. On the side of the turntable, there are two sets of rope assemblies installed. On the right side of the installation shell and below the grip, there is an installation frame assembly fixedly installed. The installation frame assembly includes a C-shaped frame. At the bottom of the C-shaped frame and directly below the installation shell, there is a roller assembly rotatably installed.

[0008] Preferably, the rope assembly includes a main rope. Outside the main rope, there is an outer sleeve installed. Inside the outer sleeve, there are several installation grooves opened, and inside the installation grooves, barbs are inserted and installed. One end of the barb is fixedly connected to the main rope. One end of the main rope is fixedly installed with a connecting lasso, and the connecting lasso is fixedly connected to the turntable.

[0009] Preferably, at the top of the C-shaped frame and directly below the turntable, there is a clamping groove opened, and the bottom of the turntable is snap-fitted with the clamping groove.

[0010] Preferably, on one side of the top of the C-shaped frame, there is a blower fixedly installed. At the position where the blower is installed on the C-shaped frame, there are several ventilation openings opened. Inside the C-shaped frame, there are several diversion grooves opened, and the diversion grooves all face the direction of the clamping groove.

[0011] Preferably, the roller assembly includes an axle frame. The axle frame is rotatably connected to the bottom of the C-shaped frame. At the bottom of the axle frame, there is an installation cover fixedly installed. Inside the installation cover, there is an installation shaft penetratingly installed. On the outside of the installation shaft, there are several buffer belts installed, and on the outside of the buffer belts, there are support wheels fixedly installed.

[0012] Preferably, on the outer surface of the support wheel, there are raised anti-slip patterns provided, and the support wheel and the buffer belt are made of high-elasticity materials, such as rubber or silicone.

[0013] Preferably, on one side of the top of the installation shell, there is a wire passing groove opened. On the other side of the top of the installation shell, there is a display screen fixedly installed. At the top inside the installation shell, there is an expansion rod control box fixedly installed, and the expansion rod control box is electrically connected to the electric telescopic push rod through a cable.

[0014] Preferably, on the outside of the grip, there is a sleeve installed. On the side of the sleeve, there is a handle rotatably installed. On the front and back sides of the sleeve, there are operating rods fixedly installed. On the outside of the grip, there is a controller fixedly installed.

[0015] Preferably, keyholes are provided on the front and rear sides of the grip, and a release lock button is fixedly installed outside the keyhole. A lock catch is provided on the side of the storage battery, and the lock catch is engaged with the keyhole inside the grip.

[0016] Preferably, protective plates are fixedly installed on the front and rear sides and the left side of the installation shell, and heat dissipation windows are opened inside the protective plates.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: By installing a roller assembly at the bottom of the C-shaped frame, the present invention elastically supports the bottom of the device through the roller assembly, enabling most of the overall weight of the device to be applied to the ground, greatly reducing the burden on the user's arms caused by the overall weight of the device, saving manpower, facilitating the user to push and pull the device, and being beneficial to improving the accuracy of the mowing work.

[0018] By installing a roller assembly at the bottom of the C-shaped frame, the present invention can quickly move the device by using the roller assembly. During the movement, the cutting angle can be adjusted with the roller assembly as the center point, and under the supporting action of the roller assembly, the height of the rope assembly from the ground is always kept consistent, so that the mowing effect of the device is unified.

[0019] By providing a diversion groove inside the C-shaped frame, the present invention can direct the high-pressure air blown by the blower through the diversion groove, so that the air flow blows from the diversion groove to the turntable. Then, when the turntable drives the rope assembly to mow the grass, a horizontal thrust can be applied to the cut grass and shrub branches, so as to blow the grass and shrub branches away from the user. This can not only achieve the anti-splash effect, but also prevent the cut grass and shrub branches from continuously colliding inside the device and causing damage to the device.

[0020] By installing a rope assembly on the side of the turntable, and through the barbs installed in the rope assembly, the present invention can increase the friction on the surface of the rope assembly. Compared with traditional cotton ropes or nylon ropes, when using the rope assembly to mow the grass, it can effectively cut plants, thus greatly improving the efficiency of the device in mowing work, and enabling the device to be applied to the trimming of green belts with thicker branches, expanding the application range of the device.

Detailed implementation manners

[0023] The technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] As Figures 1 - 8 shown, a new type of handheld lawn mower proposed by the present invention includes a mounting shell 1, a rope assembly 2, a mounting frame assembly 3 and a grip 4. The grip 4 is a hollow columnar structure. An electric telescopic push rod 403 is installed on the left side of the grip 4. An electrical box 407 is fixedly installed inside the grip 4. A battery 406 extending into the grip 4 is plugged and installed at the top of the grip 4, and the battery 406 is electrically connected to the electrical box 407. The grip 4 can provide a mounting position for the surrounding components and is convenient for the user to hold the device, facilitating the movement of the device. The electric telescopic push rod 403 can extend or contract, thereby adjusting the angle between the grip 4 and the mounting shell 1 to adjust the device to an appropriate angle for work. The electrical box 407 can connect the battery 406 and use a cable to connect other circuit components to supply power to the device and control other circuit components to work synchronously. The battery 406 can be installed inside the grip 4 by plugging and is inserted and connected to the top of the electrical box 407, so that the internal circuit of the battery 406 and the electrical box 407 forms a path to facilitate power supply to the device, enabling the device to work outdoors without a power connection; On the left side of the grip 4, there is an installation shell 1. On the right side of the installation shell 1, there is a connecting shaft 106, and the right side of the connecting shaft 106 is connected to the grip 4. The right side of the installation shell 1 is rotatably connected to one end of the electric telescopic push rod 403. At the bottom inside the installation shell 1, there is a fixed installation of a motor 108. The output shaft of the motor 108 extends to the bottom of the installation shell 1 and is installed with a turntable 107. At the bottom of the installation shell 1, there is a rotatable installation of a support disk 102, and on the side of the support disk 102, there are equally spaced blades 103 installed. The installation shell 1 can provide an installation position for the surrounding components. The connecting shaft 106 can axially connect the installation shell 1 and the grip 4, so that when the electric telescopic push rod 403 extends or contracts, the angle between the grip 4 and the installation shell 1 changes, thereby making the working state of the device more in line with the ergonomics of the user and providing a more comfortable working posture for the user. The motor 108 adopts the YE4 - 300KW type. After the motor 108 is powered on, it can rotate, and then drive the turntable 107 and the rope assembly 2 outside it to rotate at high speed, so that the rope assembly 2 is straightened under the action of centrifugal force and cuts grass or shrub branches. The turntable 107 can rotate at high speed along with the output shaft of the motor 108, thereby driving the rope assembly 2 to rotate at high speed. The support disk 102 is rotatably connected to the bottom of the installation frame, and a through hole is provided at the central position of the support disk 102 to facilitate the installation position for the output shaft of the motor 108. When the device switches from the horizontal state to the vertical state for work, the support disk 102 can be used to contact the ground to support the device, thereby saving manpower during the working state of the device. At the same time, the blades 103 on the side of the support disk 102 can rely on the self - weight of the device itself and cut the grass and shrub branches that are relatively difficult to cut by rolling the support disk 102, thereby increasing the functionality of the device; On the side of the turntable 107, there are two groups of rope assemblies 2 installed. The rope assemblies 2 can rotate synchronously with the turntable 107. When the rope assemblies 2 rotate at high speed, they are straightened under the action of centrifugal force, and the straightened rope assemblies 2 contact the grass and shrub branches, thereby realizing the cutting of the grass and shrub branches; On the right side of the installation shell 1 and below the grip 4, there is a fixed installation of an installation frame assembly 3. The installation frame assembly 3 includes a C - shaped frame 303. The installation frame assembly 3 can provide an installation position for the surrounding components. The C - shaped frame 303 can be fixedly connected to the installation shell 1 and provide an installation position for other surrounding components; At the bottom of the C - shaped frame 303 and directly below the installation shell 1, there is a rotatable installation of a roller assembly 5. The roller assembly 5 can support the bottom of the device. At the same time, when passing through an uneven road surface, it can use the elasticity of the roller assembly 5 itself to reduce the longitudinal movement amplitude during the movement and working process of the device, so that when the device mows the grass, the cutting length of the grass or shrub branches can be relatively kept consistent, improving the cutting effect of the device on the grass or shrub branches.

[0025] Further, the rope assembly 2 includes a main rope 204. An outer sleeve 202 is sleeved outside the main rope 204. A plurality of mounting grooves are formed inside the outer sleeve 202, and barbs 203 are inserted and mounted inside the mounting grooves. One end of the barb 203 is fixedly connected to the main rope 204. A connecting lasso 201 is fixedly mounted at one end of the main rope 204, and the connecting lasso 201 is fixedly connected to the turntable 107. The main rope 204 can provide a mounting position for the surrounding components, and through the connection of the connecting lasso 201 and the turntable 107, it can drive other components on the outside to perform high-speed centrifugal motion synchronously during high-speed rotation. The outer sleeve 202 can be sleeved outside the main rope 204 to provide protection for the main rope 204, avoiding the breakage of the single main rope 204 under high-intensity use and affecting the mowing effect. The barb 203 can increase the friction between the rope assembly 2 and grass and shrub branches, making it easier to cut the grass and shrub branches, which helps to improve the overall mowing effect and efficiency of the device. The connecting lasso 201 can be connected to the turntable 107, so that when the turntable 107 rotates at high speed, it drives the rope assembly 2 to perform high-speed centrifugal circular motion, facilitating the rapid cutting of grass and shrub branches.

[0026] Further, a card slot 301 is formed at the top of the C-shaped frame 303 directly below the turntable 107, and the card slot 301 is snap-fitted with the bottom of the turntable 107. The card slot 301 can be snap-fitted with the turntable 107, so as to improve the stability of the bottom of the turntable 107 when the turntable 107 rotates at high speed, prevent the turntable 107 from having eccentric motion during high-speed rotation, and thus avoid affecting the overall stability of the device.

[0027] Further, a blower 304 is fixedly mounted on one side of the top of the C-shaped frame 303. A plurality of ventilation openings are formed in the C-shaped frame 303 at the installation position of the blower 304. A plurality of diversion grooves 302 are formed inside the C-shaped frame 303, and the diversion grooves 302 all face the direction of the card slot 301. The blower 304 is of the DBMX300 type. After the blower 304 is powered on, it can blow high-speed air into the inside of the C-shaped frame 303. Then, under the guidance of the plurality of diversion grooves 302, the high-speed air flows towards the turntable 107, so that the grass and shrub branches cut by the rope assembly 2 are blown by the high-speed air and move away from the user side, thus avoiding harm to the user's respiratory tract and at the same time avoiding the splashing of uncrushed grass and shrub branches, thereby preventing the splashed grass and shrub branches from coming into contact with the components inside the C-shaped frame 303 again and causing damage to the components inside the C-shaped frame 303.

[0028] Further, the roller assembly 5 includes an axle bracket 501 which is rotatably connected to the bottom of the C-shaped bracket 303. A mounting cover 505 is fixedly installed at the bottom of the axle bracket 501. An installation shaft 504 is installed through the interior of the mounting cover 505. A number of buffer belts 503 are installed on the outer side of the installation shaft 504, and a support wheel 502 is fixedly installed on the outer side of the buffer belt 503. The axle bracket 501 can be rotatably connected to the C-shaped bracket 303, so that the axle bracket 501 and the components at its bottom can rotate 360 degrees, facilitating the adjustment of the moving direction of the device. The mounting cover 505 can rotatably install the installation shaft 504, so that the installation shaft 504 is connected to the buffer belt 503 and the support wheel 502. The buffer belt 503 elastically connects the support wheel 502 and the installation shaft 504. At the same time, the support wheel 502 supports the whole device, making the device easy to move and reducing the influence of uneven ground on the longitudinal movement amplitude during the movement of the device.

[0029] Further, the outer surface of the support wheel 502 is provided with raised anti-slip lines, and the support wheel 502 and the buffer belt 503 are made of high-elastic materials such as rubber or silica gel. The support wheel 502 can facilitate the movement of the device. Under the action of the pressure of the device, after the support wheel 502 deforms, the contact area between the support wheel 502 and the ground can be increased, so as to be applicable to uneven ground such as lawns, improving the passability of the device and facilitating the movement of the device to irregular ground for work.

[0030] Further, a wire groove 101 is opened on one side of the top of the installation shell 1, and a display screen 105 is fixedly installed on the other side of the top of the installation shell 1. A telescopic rod control box 109 is fixedly installed at the top inside the installation shell 1, and the telescopic rod control box 109 is electrically connected to the electric telescopic push rod 403 through a cable. The wire groove 101 can provide space for the installation and laying of the cable, so that the components inside the installation shell 1 can be connected to the external components through several cables. The display screen 105 can display the data in the working state of the device, facilitating the user to view information such as power and rotation speed. The telescopic rod control box 109 can be connected to the electric telescopic push rod 403 through a cable, thereby controlling the electric telescopic push rod 403 to extend or retract, so that under the action of the electric telescopic push rod 403, the included angle between the grip 4 and the installation shell 1 is adjusted, enabling the device to adapt to different holding postures of users and terrains for adaptive adjustment.

[0031] Further, a sleeve 404 is installed on the outer side of the grip 4. A handle 401 is rotatably installed on the side surface of the sleeve 404, and operating rods 405 are fixedly installed on the front and rear sides of the sleeve 404. A controller 402 is fixedly installed on the outer side of the grip 4. The sleeve 404 is made of a plastic material with good insulation, which can prevent the circuit components inside the grip 4 from leaking electricity. Thus, when holding the sleeve 404, the operating rods 405 and the handle 401 on the outer side of the sleeve 404, the safety of the user can be ensured. The handle 401 and the operating rods 405 can respectively facilitate lifting and pulling the device, thereby facilitating the user to move the device. The controller 402 can be electrically connected to other circuit components through a cable, and thus other circuit components inside the device can be controlled through the controller 402, enabling the device to work in a set state.

[0032] Further, keyholes are provided on the front and rear sides of the grip 4, and a release lock button is fixedly installed on the outer side of the keyhole. A lock catch is provided on the side surface of the battery 406, and the lock catch is snap-connected to the keyhole inside the grip 4. Through the cooperation of the keyhole and the lock catch, the battery 406 can be limited and fixed, and by pressing the release lock button, the lock catch can be separated from the keyhole, thereby facilitating the replacement of the battery 406.

[0033] Further, protective plates 104 are fixedly installed on the front and rear sides and the left side of the installation shell 1, and heat dissipation windows are opened inside the protective plates 104. The protective plates 104 can improve the protection effect of the installation shell 1 on the internal components. At the same time, the heat dissipation windows provided inside the protective plates 104 can enable the air inside and outside the installation shell 1 to circulate, thereby dissipating heat from the components inside the installation shell 1 and preventing the motor 108 from overheating and shutting down during continuous operation.

[0034] Working principle: After inserting the storage battery 406 into the grip 4, connect the storage battery 406 to the electrical box 407. Control the storage battery 406 to supply power to other circuit components inside the device through the electrical box 407. Set parameters for multiple circuit components inside the device through the controller 402 to make the electric telescopic push rod 403 extend or contract, and adjust the angle between the grip 4 and the mounting shell 1 to an appropriate value. Place the device on the ground, and support and buffer the device through the roller assembly 5. After the motor 108 is powered on and rotates, it drives the turntable 107 and the rope assembly 2 to rotate at high speed. The user holds the operating rod 405 with both hands and pulls the device to move. Move the rope assembly 2 close to the lawn or shrub branches to be cut, make the rope assembly 2 contact the grass and shrub branches, and complete the cutting of the grass and shrub branches. At the same time, after the blower 304 is powered on, it blows high-speed air into the inner side of the C-shaped frame 303. After guiding the high-speed air through the diversion groove 302, the high-speed air blows horizontally towards the turntable 107 and blows away the grass and shrub branches cut by the rope assembly 2. By reciprocally pulling or pushing the device, the device continuously changes its position under the support of the roller assembly 5, expands the cutting range of the device, and enables the device to complete the cutting of weeds or shrubs in the specified area. When cutting the edge of the lawn, turn the device 90 degrees to change the turntable 107 from a horizontal state to a vertical state, and make the blade 103 on the side of the support disk 102 contact the ground. Use the support disk 102 to support the device instead of the roller assembly 5. At the same time, push and pull the device to move, and make the high-speed rotating rope assembly 2 contact the lawn to complete the cutting, thereby enabling the trimming of the lawn or shrubbery.

[0035] The above specific embodiments are only several preferred embodiments of the present invention.
