Description

Technical Field

[0001] This utility model relates to the technical field of yard snowplows and lawn mowers, specifically a dual-function electric push-type lawn mower and snowplow with replaceable blades. Background Technology

[0002] A lawnmower, also known as a lawn mower, lawn trimmer, or lawn trimmer, is a mechanical tool used for mowing lawns and vegetation. A snowplow is a mechanical device used to clear snow from yard paths, driveways, and other areas, quickly and efficiently clearing snow after a snowfall. In outdoor maintenance, lawn mowing and snow removal are two important and distinctly seasonal tasks. Traditionally, lawnmowers are used for lawn mowing, and snowplows are used for snow removal.

[0003] Traditionally, lawnmowers and snowplows are two separate pieces of equipment. For users who need to handle both mowing and snow removal simultaneously, such as typical villa owners or property managers, they must purchase separate lawnmowers and snowplows. This not only increases the initial purchase cost, but the storage space required for both devices further increases operating costs.

[0004] Therefore, it is necessary to propose a dual-function electric push-type lawn mower and snowplow with replaceable blades for ordinary courtyard residents in response to the above technical solutions. Utility Model Content

[0005] The purpose of this invention is to provide a dual-function electric push-type lawnmower and snowplow with replaceable blades, addressing the problem mentioned in the background section that traditional lawnmowers and snowplows are two separate devices. For users who need to handle both mowing and snow removal simultaneously, such as ordinary villa residents and property managers, they must purchase separate lawnmowers and snowplows. This not only increases the initial purchase cost, but also requires storage space for both devices, further increasing operating costs.

[0006] To solve the above problems, this utility model provides the following technical solution: a dual-function electric push-type lawn mower and snow remover with replaceable blades, comprising a main body housing and a lawn mowing and snow removal unit:

[0007] The main housing has rear wheels on both sides. Adjustable brackets are rotatably mounted on the front wheels on both sides of the main housing. A locking structure is provided between the adjustable brackets and the main housing. A front wheel is located at the bottom of the adjustable bracket. The adjustable brackets rotate to adjust the tilt angle of the front wheels. The mowing and snow removal unit is located inside the main housing. The mowing and snow removal unit has a working shaft rotatably mounted inside the main housing. A power source is located inside the main housing to drive the working shaft to rotate. A blade holder is mounted on the working shaft. A snow removal blade is detachably mounted on the blade holder via a self-locking nut. An L-shaped mowing blade is detachably mounted on the blade holder via a self-locking nut.

[0008] By adopting the above technical solution, it is possible to easily switch between mowing and snow removal operations according to actual needs. When mowing is required, a mowing knife is installed; when snow removal is required, it is replaced with a snow removal knife. At the same time, the adjustment frame rotates to adjust the tilt angle of the front wheel. When mowing, the adjustment frame is pulled back to make the front wheel upright, with the mowing knife 45 mm off the ground. When shoveling snow, the adjustment frame is pushed forward, causing the front wheel to tilt back 25° to reduce propulsion resistance, and the snow removal knife is 3 mm off the ground.

[0009] Preferably, the main housing also has a handrail on the top of the main housing, and the top of the main housing has a discharge port communicating with the inside of the main housing. A guide tube is rotatably nested on the top of the discharge port, and a grass collection bag is detachably installed on the guide tube.

[0010] By adopting the above technical solution, a comfortable operating method can be provided for operators, who can easily push the lawnmower and snowplow for operation via the handle. During lawnmowing, the cut grass can be collected in the grass collection bag through the discharge port and guide tube, keeping the work site clean. The discharge port also serves as a snow guide, and the rotatable design of the guide tube allows for adjustment of the direction of grass collection or snow guiding according to actual conditions.

[0011] Preferably, the main housing also has limiting plates on both sides of the main housing, and the sides of the limiting plates are provided with two slots with different inclination angles. The inner side of the adjustment frame is provided with a locking block, which engages with the slots on the sides of the limiting plates.

[0012] By adopting the above technical solution, the rotation angle of the adjustment frame can be precisely positioned and locked. When the adjustment frame rotates, the locking block engages with the slots of the limiting plate at different tilt angles, thus fixing the position of the adjustment frame.

[0013] Preferably, the mowing and snow removal unit also has a Hall switch located on the side of the main unit housing. A motor is installed inside the main unit housing, and the Hall switch is connected to the motor. The adjustment frame rotates to change its tilt angle and abuts against the Hall switch.

[0014] By adopting the above technical solution, the working state of the motor can be controlled according to the tilt angle of the adjustment frame. When the adjustment frame rotates to a specific angle and comes into contact with the Hall switch, the Hall switch will transmit a signal to the motor to start and stop the motor, which, together with the front protective plate during mowing, ensures the safety of operation.

[0015] Preferably, the main unit housing has a snow inlet at the front and a safety insert plate that is vertically slidably disposed at the snow inlet, the insert plate abutting against a Hall switch.

[0016] By adopting the above technical solution, the device can be inserted into the snow inlet through the insert plate when mowing grass, so as to prevent the open snow inlet from causing danger.

[0017] Preferably, the grass-cutting and snow-removing unit also has a transmission wheel disposed at the motor output end, a transmission wheel disposed on the side of the working shaft, and a transmission belt is disposed between the transmission wheel at the motor output end and the transmission wheel disposed on the side of the working shaft and the transmission belt is used for transmission connection.

[0018] By adopting the above technical solution, the power of the motor can be smoothly transmitted to the working shaft. The elasticity of the transmission belt can buffer the impact force during motor start-up and operation, reduce equipment vibration and wear, extend the service life of the motor and working shaft, and also facilitate equipment maintenance and parts replacement.

[0019] Preferably, the lawn mower is L-shaped with a hardened steel blade and a 25° blade angle, and the snowplow is C-shaped with a rubber-coated blade.

[0020] By adopting the above technical solutions, lawnmowers can achieve excellent cutting performance. The hardened steel material ensures the blade's hardness and wear resistance, while the 25° blade angle allows for more effective cutting of grasses, improving mowing efficiency. The C-shaped blade of the snowplow knife better collects and pushes away snow, and the rubber coating reduces friction and collisions between the snowplow and the ground or other objects, lowering noise and preventing scratches on the ground.

[0021] Compared with existing technologies, the advantages of this utility model are: by incorporating a grass-cutting and snow-shoveling unit, it allows for convenient switching between grass-cutting and snow-shoveling operations as needed. When grass cutting is required, a grass-cutting blade is installed; when snow removal is required, it is replaced with a snow-shoveling blade, achieving interchangeable grass-cutting / snow-shoveling functions. Simultaneously, the adjusting frame rotates to adjust the tilt angle of the front wheels. When grass cutting, the adjusting frame is pulled back to make the front wheels upright, with the grass-cutting blade 45 mm off the ground. When snow removal, the adjusting frame is pushed forward, causing the front wheels to tilt back 25°, reducing propulsion resistance. Combining the snowplow and snow-shovel into one unit reduces purchase costs by 40% and saves 50% of storage space. Attached Figure Description

[0029] 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.

[0030] like Figures 1 to 6 As shown, this embodiment provides a technical solution: a dual-function electric push mower and snowplow with replaceable blades, including a main housing 1 and a mowing and snowplow unit 2.

[0031] The main housing 1 has rear wheels 102 located on both sides of the main housing 1. Adjustment frames 103 are rotatably mounted on both sides of the main housing 1, and a locking structure is provided between the adjustment frames 103 and the main housing 1. A front wheel 105 is located at the bottom of the adjustment frame 103. Rotation of the adjustment frame 103 adjusts the tilt angle of the front wheel 105. The mowing and snow removal unit 2 is located inside the main housing 1. The mowing and snow removal unit 2 has a working shaft 201 rotatably mounted inside the main housing 1. A power source is located inside the main housing 1 to drive the working shaft 201 to rotate. A blade holder 202 is located on the side of the working shaft 201. A snow removal blade 203 and a grass cutter 204 are detachably mounted on the blade holder 202 via self-locking nuts. This allows for easy switching between mowing and snow removal operations as needed. When mowing is required, the grass cutter 204 is installed; when snow removal is required, the snow removal blade 203 is used. At the same time, the adjustment frame 103 rotates to adjust the tilt angle of the front wheel 105. When mowing, the adjustment frame 103 pulls back to make the front wheel 105 upright, and the mowing blade 204 is 45 mm off the ground. When shoveling snow, the adjustment frame 103 pushes forward, so that the front wheel 105 is delayed and tilted back 25° to reduce the propulsion resistance.

[0032] Please see Figure 4 , Figure 5 and Figure 6 This embodiment provides a technical solution: a dual-function electric push mower and snowplow with replaceable blades, comprising a main housing 1 and a mowing and snowplow unit 2.

[0033] A handle 101 is provided on the top of the main housing 1. A discharge port 107, communicating with the interior of the main housing 1, is also provided on the top of the discharge port 107. A guide tube 108 is rotatably nested on the top of the discharge port 107. A grass collection bag is detachably mounted on the guide tube 108, providing a comfortable operating method for the operator. The handle 101 facilitates the pushing of the lawnmower and snowplow for operation. During mowing operations, the cut grass can be collected in the grass collection bag through the discharge port 107 and the guide tube 108, keeping the work site clean. The discharge port 107 also serves as a snow guide, and the rotatable design of the guide tube 108 allows for adjustment of the direction of grass collection or snow guiding as needed.

[0034] Limiting plates 106 are provided on both sides of the main housing 1. The sides of the limiting plates 106 have two slots with different inclination angles. The inner side of the adjusting frame 103 is provided with a locking block 104. The locking block 104 engages with the slots on the sides of the limiting plates 106, which can precisely position and lock the rotation angle of the adjusting frame 103. When the adjusting frame 103 rotates, the locking block 104 engages with the slots of the limiting plates 106 at different inclination angles, which can fix the position of the adjusting frame 103.

[0035] A Hall switch 207 is installed on the side of the main housing 1, and a motor 205 is installed inside the main housing 1. The Hall switch 207 is connected to the motor 205. The adjusting bracket 103 rotates to change its tilt angle and abuts against the Hall switch 207. The operating state of the motor 205 can be controlled by adjusting the tilt angle of the adjusting bracket 103. When the adjusting bracket 103 rotates to a specific angle and abuts against the Hall switch 207, the Hall switch 207 will transmit a signal to the motor 205 to start and stop the motor 205, ensuring safe operation.

[0036] The main housing 1 has a snow inlet on its side. The main housing 1 also has a vertically sliding insert plate 109 mounted on the snow inlet. The insert plate 109 abuts against a Hall switch 207, allowing the device to be inserted into the snow inlet during mowing to prevent danger from an open snow inlet. The Hall switch 207 operates based on changes in the magnetic field caused by changes in the position of the adjusting bracket 103 or the insert plate 109. When the adjusting bracket 103 rotates to a specific angle or the insert plate 109 slides to a specific position, the surrounding magnetic field changes. The Hall switch 207 senses this change and transmits a signal to the motor 205, thereby controlling the operating state of the motor 205.

[0037] A drive pulley is provided at the output end of the motor 205, and another drive pulley is provided on the side of the working shaft 201. A drive belt 206 is provided between the drive pulley at the output end of the motor 205 and the drive pulley on the side of the working shaft 201, and the drive belt 206 provides a transmission connection, which enables the power of the motor 205 to be smoothly transmitted to the working shaft 201. The elasticity of the drive belt 206 can buffer the impact force during the start-up and operation of the motor 205, reduce the vibration and wear of the equipment, extend the service life of the motor 205 and the working shaft 201, and also facilitate the maintenance and replacement of parts of the equipment.

[0038] The lawnmower 204 features an L-shaped blade made of hardened steel with a 25° cutting angle. The snowplow 203 has a C-shaped blade covered with rubber, which enhances the lawnmower's cutting performance. The hardened steel material ensures the blade's hardness and wear resistance, while the 25° cutting angle allows for more effective cutting of grasses, improving mowing efficiency. The snowplow 203's C-shaped blade better collects and pushes snow, and the rubber coating reduces friction and impact with the ground or other objects, lowering noise and preventing scratches.

[0039] Working principle: The operator can switch between mowing and snow removal operations as needed. When mowing is required, the operator first removes the snow removal blade 203 from the blade holder 202 by unscrewing the self-locking nut, and then installs the mowing blade 204 onto the blade holder 202 using the self-locking nut. Next, the operator pulls the adjusting frame 103 backward to rotate it, causing the front wheel 105 to stand upright. At this time, the locking block 104 engages with the corresponding slot in the limiting plate 106 for the mowing operation, fixing the position of the adjusting frame 103. Simultaneously, the mowing blade 204 is raised 45 mm off the ground, and the insert plate 109 is inserted into the snow inlet on the side of the main housing 1 to prevent the open snow inlet from causing danger. Magnets are installed inside both the adjusting frame 103 and the insert plate 109. When the adjusting frame 103 rotates to a specific angle corresponding to the mowing operation and the insert plate 109 slides to a specific position for insertion into the snow inlet, they will change the surrounding magnetic field. After the Hall switch 207 senses these changes in the magnetic field, it transmits a signal to the motor 205, which starts. The transmission wheel at the output end of the motor 205 smoothly transmits power to the working shaft 201 through the transmission belt 206, driving the working shaft 201 to rotate, thereby driving the blade holder 202 and the mowing blades 204 mounted on the blade holder 202 to rotate for mowing operations. The cut grass enters the grass collection bag through the discharge port 107 and the guide tube 108 for collection. The operator pushes the mowing and snow removal machine through the handle 101 on the top of the main housing 1 for operation. When snow removal is required... At this time, the operator first removes the grass cutter 204 from the blade holder 202 by unscrewing the self-locking nut, then installs the snow removal blade 203 onto the blade holder 202 using the self-locking nut. Next, the operator pushes the adjusting frame 103 forward, causing it to rotate and the front wheel 105 to tilt backward at 25°. At this point, the locking block 104 engages with the corresponding slot on the limiting plate 106, fixing the position of the adjusting frame 103 and reducing pushing resistance. Simultaneously, the insert plate 109 is pulled out from the snow inlet. When the adjusting frame 103 rotates to the specific angle corresponding to the snow removal operation and the insert plate 109 slides to the specific position where it is pulled out from the snow inlet, the surrounding magnetic field changes again. The Hall switch 207 senses these magnetic field changes and transmits a signal to the motor 205. The motor 205... Upon startup, the transmission wheel at the output end of motor 205 transmits power to the working shaft 201 via transmission belt 206, driving the working shaft 201 to rotate. This, in turn, drives the blade holder 202 and the snow removal blades 203 mounted on the blade holder 202 to rotate for snow removal. Snow enters the main housing 1 through the snow inlet. The C-shaped blades of the snow removal blades 203 better collect and push the snow, guiding it in a designated direction through the discharge port 107 and the rotatable guide tube 108. The operator also pushes the snow mower using the handle 101. Throughout the operation, the elasticity of the transmission belt 206 buffers the impact of motor 205 startup and operation, reducing equipment vibration and wear, and extending the service life of motor 205 and working shaft 201.This also facilitates equipment maintenance and parts replacement. Furthermore, the Hall switch 207 controls the operating state of the motor 205 by controlling the magnetic field changes caused by positional changes in the adjusting bracket 103 or the insert plate 109, ensuring operational safety.
