Description

Technical Field

[0001] This application relates to the field of lawn mowers, and more particularly to an angle-adjustable tilting lawn mower mechanism and a lawn mower. Background Technology

[0002] Weeding is a crucial step in ensuring healthy crop growth and increasing yield. Clearing weeds from field ridges requires trimming not only the weeds on the surface of the ridges (the plane directly exposed to walking traffic) but also those on the sides. However, existing weeding machines have blind spots; due to their simple structure, they cannot effectively remove weeds from the edges of the ridges. Furthermore, because field ridges have varying slopes, to enable the improved weeding machine to effectively trim weeds on the sides of ridges with different slopes, the cutter head structure is designed to be movable, maintaining the machine's balance even when the cutter head is in motion. Utility Model Content

[0003] To overcome the shortcomings of the prior art, this application provides an angle-adjustable tilting weeding mechanism, including a frame and a drive component. The frame includes a horizontal housing and a swing housing. The horizontal housing is fixedly connected to a horizontal cutting component, and the swing housing is fixedly connected to a swing cutting component. Both the horizontal cutting component and the swing cutting component are drivenly connected to the output end of the drive component.

[0004] The horizontal housing has a front wheel and a rear wheel mounted below it along its forward and backward direction. The swing housing is pivotally connected to the horizontal housing via a horizontally mounted pivot and is configured to swing up and down in the vertical direction around the pivot. The swing housing is hinged to the middle of the handle via a handle pin locked above it. The upper part of the handle is penetrated by a limiting pin. A vertical member is fixed to the upper part of the swing housing, and the vertical member has several angle adjustment holes that are adapted to the limiting pin along the swing trajectory of the upper part of the handle. The lower part of the handle extends to the lower part of the swing housing and is fixed to the side wheel.

[0005] This application provides an angle-adjustable tilting weeding mechanism, including a frame and a drive unit. The frame includes a horizontal housing and a swing housing. The horizontal housing is fixedly connected to a horizontal cutting assembly, and the swing housing is fixedly connected to a swing cutting assembly. Both the horizontal cutting assembly and the swing cutting assembly are drivenly connected to the output end of the drive unit.

[0006] The horizontal housing has a front wheel and a rear wheel mounted below it along its forward and backward direction. The swing housing is pivotally connected to the horizontal housing via a horizontally mounted pivot and is configured to swing up and down in the vertical direction around the pivot. The swing housing is hinged to the middle of the handle via a handle pin locked above it. The upper part of the handle is penetrated by a limiting pin. A vertical member is fixed to the upper part of the swing housing, and the vertical member has several angle adjustment holes that are adapted to the limiting pin along the swing trajectory of the upper part of the handle. The lower part of the handle extends to the lower part of the swing housing and is fixed to the side wheel.

[0007] In one possible implementation, both the front wheel and the rear wheel are driven to the output end of the drive unit, and the output end of the drive unit is also driven to the horizontal cutting assembly, which has a torque that is transmitted to the output end of the swing cutting assembly.

[0008] In one possible implementation, the output end of the drive unit is driven by a first belt, and the other end of the first belt away from the output end of the drive unit forms a belt drive with the horizontal cutting assembly. The horizontal cutting assembly is driven by the swing cutting assembly through a telescopic transmission rod.

[0009] In one possible implementation, the output end of the drive unit is driven by a second belt, and the other end of the second belt away from the output end of the drive unit forms a belt drive with the output end of the rear-drive gearbox, and the output end of the rear-drive gearbox is driven by the front wheel and the rear wheel.

[0010] In one possible implementation, both the horizontal cutting assembly and the oscillating cutting assembly include:

[0011] Cutter head shaft;

[0012] A cutter head, wherein the cutter head shaft is inserted into the center of the cutter head and can rotate around the axial direction of the cutter head shaft, and a plurality of cutting blades are arranged at intervals around the edge of the cutter head;

[0013] A protective cover is installed upward on the cutter head, forming a closed area and covering the cutter head shaft.

[0014] In one possible implementation, protective portions are formed extending downward from the edges of the horizontal housing and the swing housing.

[0015] This application also provides a lawnmower, including the aforementioned angle-adjustable tilting weeding mechanism.

[0016] Compared to existing technologies, the beneficial effects of this application are as follows: This device adjusts the swing amplitude of the swing housing to adapt to the slope of the field ridge, thereby enabling the swing cutting component installed on the swing housing to effectively clear weeds growing on the side of the field ridge. The position of the side wheels can be adjusted by rotating the handle around the handle pin, ensuring that the side wheels can always touch the ground and form a grip point regardless of the swing angle of the swing housing. This maintains that the entire machine has three grip points: the front wheel, the rear wheel, and the side wheel. This allows the machine to maintain its balance even when the swing housing swings up and down within a certain range, preventing the device from tipping over. Attached Figure Description

[0028] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0029] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components.

[0030] In this application, unless otherwise expressly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact with the second feature through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0031] When clearing weeds from paddy field ridges, it's necessary to trim weeds on the surface of the ridges (the plane directly in contact with pedestrians) as well as those on the sides. However, weeding machines have significant blind spots; due to their simple structure, they cannot effectively remove weeds from the edges of the ridges. Furthermore, because paddy field ridges have varying slopes, to enable the improved weeding machine to target different slopes, the cutter head structure for trimming weeds on the sides of the ridges is designed to be movable, while maintaining the machine's overall balance even when this cutter head structure is in motion.

[0032] To address the above issues, an angle-adjustable tilting weeding mechanism is proposed. The aim is to enable this weeding structure to perform weeding operations on field ridges with different side slopes, while maintaining the overall balance of the machine during weeding.

[0033] Please see Figure 1 and Figure 2 , Figure 1 An angle-adjustable tilting weeding mechanism is provided, including a frame and a drive unit 7. The frame includes a horizontal housing 1 and a swing housing 4. A horizontal cutting component is fixedly mounted on the horizontal housing 1, and a swing cutting component is fixedly mounted on the swing housing 4. Both the horizontal cutting component and the swing cutting component are drively connected to the output end of the drive unit 7. The horizontal cutting component is configured to clear weeds on the upper surface of the field ridge, and the swing cutting component is configured to clear weeds on the side of the field ridge.

[0034] In some embodiments, the frame mainly consists of three parts: a support plate, a horizontal housing 1, and a swing housing 4. A drive unit 7 is mounted on the support plate, which is located at the rear end of the machine and is higher than the horizontal housing 1 and the swing housing 4 above the ground. In some application scenarios, the horizontal housing 1 and the swing housing 4 are roughly on the same horizontal plane. In this case, the machine is equivalent to having two weeding mechanisms with blades 22 arranged side by side. Although it cannot weed the sloping blind areas on the outside of the field ridge, it is equivalent to increasing the coverage area of ​​the blades, making it suitable for weeding the walking surface of wider field ridges.

[0035] In some embodiments, the drive component 7 refers to a diesel engine including an air-cooled or water-cooled structure. Alternatively, an electric motor can also be used as the drive component 7. The engine, as a power source, drives the entire machine to move back and forth and rotate the blades through a series of belts, gearboxes, and drive shafts. The engine is installed at the rear of the frame and is positioned opposite to the oscillating cutting assembly. The opposite positioning means that a dividing line is drawn at the center of the frame along the forward and backward direction of the frame. When the oscillating cutting assembly is on the left side of the frame, the engine is placed on the right side of the frame, and vice versa. This arrangement helps to maintain the balance of the entire machine.

[0036] Please see Figure 1 , Figure 3 , Figure 4 The horizontal housing 1 has a front wheel 2 and a rear wheel 3 mounted below it along its forward and backward direction. The swing housing 4 is pivotally connected to the horizontal housing 1 via a horizontally mounted pivot 6 and is configured to swing up and down in the vertical direction around the pivot 6. The swing housing 4 is hinged to the middle of the handle 10 via a pin locked above it. The upper part of the handle 10 is penetrated by a limiting pin 14. The upper part of the swing housing 4 is fixedly connected to the vertical member 12, and the vertical member 12 has several angle adjustment holes 13 that are adapted to the limiting pin 14 along the swing trajectory of the upper part of the handle 10. The lower part of the handle 10 extends to the lower part of the swing housing 4 and is fixedly connected to the side wheel 5.

[0037] The front wheel 2 and the rear wheel 3 can be driven by the same drive unit 7 (referring to the drive unit 7 used to drive the horizontal cutting component and the swing cutting component), or a separate engine can be set up to drive the whole machine forward and backward. The swing housing 4, the pivot 6 and the horizontal housing 1 form a hinge structure. The swing housing 4, as the swingable part of this structure, determines the swing amplitude of the swing housing 4 according to the slope of the side of the field ridge, so that the swing cutting component installed on the swing housing 4 can effectively cover the weeds on the side of the field ridge when cutting, so as to clear the blind spots of weeding that are difficult to handle by ordinary weeders.

[0038] When the user uses this device to weed on the field ridge, the swing housing 4 is located outside the field ridge, and the swing housing 4 can be tilted at a certain angle relative to the horizontal plane. The specific tilt angle depends on the slope of the side of the field ridge, so that the blade of the swing cutting component can fit against the weeds on the outside of the field ridge.

[0039] Please see Figure 2 and Figure 4 A fixed seat is fixed to the upper surface of the swing housing 4 by bolts. A bolt is inserted between the middle of the handle 10 and the fixed seat to form a handle pin 11, allowing the handle 10 to rotate around the handle pin 11 in a plane. The upper end of the handle 10 abuts against a limiting baffle, which serves as an upright member 12. The lower end of the limiting baffle is locked to the fixed seat or the swing housing 4 by bolts. The upper part of the handle 10 is penetrated by a limiting pin 14 in the direction facing the limiting baffle. Several angle adjustment holes 13 adapted to the limiting pin 14 are opened on the limiting baffle along the swing trajectory of the upper part of the handle 10. The multiple angle adjustment holes 13 are arranged at intervals on the limiting baffle in a curved distribution. The opening diameter of the angle adjustment holes 13 is the same as the diameter of the limiting pin 14, so that the limiting pin 14 can lock the handle 10 after passing through the limiting baffle. Since the position of the limiting baffle is fixed, the limiting pin 14 can be used to lock the rotation angle position of the handle 10. The lower part of the handle 10 extends to the bottom of the swing housing 4 and is fixedly connected to the side wheel 5 via the side wheel 5 connecting plate. Therefore, the height of the side wheel 5 can be controlled by rotating the handle 10.

[0040] The swing housing 4 is adjusted to a suitable angle so that the cutter 23 can cover a sufficiently large area along the side of the field ridge. The user manually adjusts the rotation angle of the handle 10 so that the side wheel 5 is grounded. Then, the position of the handle 10 is fixed by inserting the limiting pin 14 into the corresponding angle adjustment hole 13 to prevent the handle 10 from shifting due to engine vibration or external impact. At this time, the machine has an additional gripping point (side wheel 5 grounded) on the side of the field ridge, which increases the stability of the machine and allows it to maintain balance even when the swing housing 4 swings up and down within a certain range.

[0041] In summary, this device features two types of cutting components for weed removal, offering a wider weeding range compared to the previous single-disc weeder. By adjusting the swing amplitude of the swing housing 4 to adapt to the slope of the field ridge, the swing cutting components mounted on the swing housing 4 can effectively clear weeds growing on the side of the field ridge. The position of the side wheel 5 can be adjusted by rotating the handle 10 around the handle pin 11, ensuring that the side wheel 5 always touches the ground and forms a gripping point regardless of the swing angle of the swing housing 4. This maintains three gripping points for the machine: the front wheel 2, the rear wheel 3, and the side wheel 5. This allows the machine to maintain balance even with large up-and-down swings within a certain range, preventing the device from tipping over.

[0042] Please see Figure 2 and Figure 3 In some embodiments, both the front wheel 2 and the rear wheel 3 are driveably connected to the output end of the drive component 7. The output end of the drive component 7 is also driveably connected to the horizontal cutting assembly, which has a torque transmitted to the output end of the oscillating cutting assembly. It is understood that since the horizontal cutting assembly and the oscillating cutting assembly are driven by the same engine, and this engine is used as the driving source during movement, the engine purchase cost can be reduced, and it is convenient to synchronize the rotation speed of the cutters 23 in the two sets of cutting assemblies.

[0043] Please see Figure 2 and Figure 3 In some embodiments, the output end of the drive member 7 is connected to the first belt 8, and the other end of the first belt 8 away from the output end of the drive member 7 forms a belt drive with the horizontal cutting assembly. The horizontal cutting assembly is connected to the swing cutting assembly through a telescopic transmission rod 17.

[0044] Please see Figure 5Specifically, a pulley is installed on the output end of the drive unit 7, and the horizontal transmission structure includes a first belt 8 with one end wound around the pulley. The other end of the first belt 8, away from the pulley, is wound and connected to a pulley plate. One end of the cutting output shaft 28 is fixedly inserted into the center of the pulley plate, and the other end of the cutting output shaft 28, away from the pulley plate, is inserted into the input gear of the horizontal cutting assembly 15. In some preferred embodiments, a tensioning pulley for adjusting the tension of the first belt 8 is also abutted against it.

[0045] The horizontal cutting assembly 15 includes a horizontal tool holder reducer 16, which is a single-input, dual-output reducer. The two outputs can be achieved internally through a worm gear structure or a gear splitting structure. One output end of the reducer is connected to the cutter 23, and the other input end transmits torque to the oscillating cutting assembly via a telescopic transmission rod 17.

[0046] The telescopic transmission rod 17 includes a splined shaft and a splined sleeve fitted onto the surface of the splined shaft. Universal joints are installed at both ends of the splined sleeve, connecting the output end of the horizontal cutter head reducer 16 and the input end of the oscillating cutter head reducer 26 via the two universal joints. The oscillating cutter head reducer 26 is part of the oscillating cutting assembly and is used to transmit torque to the cutting part of the oscillating cutting assembly 27. Since the spline connection does not restrict axial movement between the splined shaft and the splined sleeve, the splined shaft can slide telescopically within the splined sleeve, thereby adjusting the overall length of the telescopic transmission rod 17. This allows for changes in the position of the oscillating housing without affecting the torque transmitted by the telescopic transmission rod 17. Simultaneously, the universal joints increase the degrees of freedom at both ends of the telescopic transmission rod, allowing the oscillating housing 4 to oscillate within a large angle range.

[0047] Please see Figure 2 and Figure 3 In some embodiments, the output end of the drive unit 7 is driven by a second belt 9, and the other end of the second belt 9 away from the output end of the drive unit 7 forms a belt drive with the output end of the rear drive gearbox 18; the first output end of the rear drive gearbox 18 is driven by a front wheel 2, and the second output end of the rear drive gearbox 18 is driven by a rear wheel 3.

[0048] Specifically, a second belt 9 is wound around the pulley at the output end of the drive unit 7. The other end of the second belt 9, away from the pulley, is wound around the input shaft of the rear-drive gearbox 18 to form a belt drive. The center of the output sprocket of the rear-drive gearbox 18 and the center of the rear wheel are connected by the rear drive shaft, forming a coaxial drive. The other end of the rear drive shaft is connected to one end of the travel drive shaft 19 through a reduction gearbox. The other end of the travel drive shaft 19 is connected to a spline joint through a universal joint, and is connected to the front wheel gearbox 20 through the spline joint. The front wheel gearbox 20 drives the front wheel 2. Since the spline joint has a certain amount of flexibility, the position of the front wheel 2 can be adjusted in the axial direction along the spline shaft of the spline joint. In addition, the part of the gearbox that drives the front wheel 2 and the rear wheel 3 to rotate is prior art and will not be described here.

[0049] Since the front wheel 2 and the rear wheel 3 share a single drive unit 7 as a power source, the device can start and stop relatively smoothly, and a reversing function can be easily added to the whole machine, thereby improving the overall availability and working efficiency of the machine.

[0050] Please see Figure 6 In some embodiments, both the horizontal cutting assembly and the oscillating cutting assembly include: a cutter head shaft 21; a cutter head 22, wherein the cutter head shaft 21 is inserted into the center of the cutter head 22 and can rotate around the axial direction of the cutter head shaft 21, and a plurality of cutting blades 23 are arranged at intervals around the edge of the cutter head 22; and a protective cover 24, wherein the cutter head 22 is provided with a protective cover 24 that forms a closed area and covers the cutter head shaft 21.

[0051] Specifically, the cutter head 22 has mounting holes and multiple first connecting holes. The mounting holes are located at the center of the cutter head 22 and are used to accommodate the cutter head shaft 21, allowing the cutter head 22 to be connected to the cutter head shaft 21. At least two sets of first connecting holes are spaced apart along the circumference of the cutter head 22. A set of second connecting holes passes through the body of the cutter 23, and each set of first connecting holes corresponds to a second connecting hole. Bolts, acting as fasteners, pass through the corresponding first and second connecting holes to fix the body of the cutter 23 to the cutter head 22. A funnel-shaped protective cover 24 covers the cutter head shaft 21 to prevent flying weeds from tangling around it.

[0052] Please see Figure 1 and Figure 2In some preferred embodiments, protective portions 25 are formed extending downward from the edges of the horizontal housing 1 and the swing housing 4 to prevent the user from accidentally touching the cutter 23 and getting injured. Specifically, the lowest point of the protective portion 25 is about 5 cm to 15 cm higher than the lowest point of the front wheel 2 to prevent the protective portion 25 from touching the ground and affecting the movement of the entire machine. Specifically, protective portions 25 are formed extending downward from the left and right sides of the horizontal housing 1 and the swing housing 4 along the forward and backward direction of the entire machine, and a protective portion 25 is also formed extending downward from the side of the horizontal housing 1 and the swing housing 4 near the rear wheel 3 to separate the blade from the rear wheel 3.

[0053] The specific working principle of this device is as follows:

[0054] 1. When the user uses this device to weed on the field ridge, the swing housing 4 is located outside the ridge, and the swing housing 4 can tilt at a certain angle relative to the horizontal plane. The specific tilt angle depends on the slope of the field ridge side, so that the blade of the swing cutting component can fit against the weeds on the outside of the ridge. The swing housing 4, the pivot 6, and the horizontal housing 1 form a hinge structure. The swing housing 4, as the swingable part of this structure, is used to adapt to the slope of the field ridge side, so that the swing cutting component installed on the swing housing 4 can effectively cover the weeds on the side of the ridge when cutting, thereby clearing the blind spots that are difficult to clean by ordinary weeders.

[0055] 2. When the swing housing 4 swings to a suitable angle so that the cutter 23 contacts the weeds on the side of the field ridge, manually adjust the rotation angle of the handle 10 to ground the side wheel 5. Then, fix the position of the handle 10 by inserting the limit pin 14 into the angle adjustment hole 13 to prevent the handle 10 from shifting due to engine vibration or external impact. Because an additional gripping point (side wheel 5) is added to the side of the field ridge, the swing housing 4 can maintain the balance of the whole machine even when swinging up and down within a certain range, preventing the device from tipping over.

[0056] 3. The horizontal cutting assembly and the oscillating cutting assembly are driven by the same engine, which is also used as the driving source during movement. This reduces the cost of purchasing the engine and facilitates the synchronous adjustment of the rotation speed of the cutter 23 in the two sets of cutting assemblies. In addition, since the front wheel 2 and the rear wheel 3 share the same engine as the power source, the device can start and stop relatively smoothly, and a reversing function can be easily added to the whole machine, thereby improving the availability and working efficiency of the whole machine.
