Description

Technical Field

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

[0002] The lawn mower on a skid steer loader is an attachment designed specifically to improve the efficiency of greening and gardening operations, and is widely used in parks, gardens, golf courses, and the agricultural field. This device is driven by the power system of the skid steer loader, has a powerful mowing ability, and can easily handle various types of grasslands and shrubs. The blades of the lawn mower are usually made of high-strength materials, with excellent wear resistance and sharpness, and can cut the lawn quickly and evenly, ensuring the neatness and beauty of the grassland.

[0003] However, the lawn mower on a general skid steer loader performs rotary motion. The rotary lawn mower uses a non-supported cutting method and needs to maintain a relatively high critical cutting speed to effectively complete the trimming work, resulting in high energy consumption. When the rotary lawn mower has a low rotational speed or the blades become dull, the grass plants will bend or slide without being completely cut, causing the surface of the lawn to be uneven. Moreover, the position transformation of the lawn mower on a general skid steer loader has great limitations. Summary of the Invention

[0004] The purpose of the present invention is to provide a reciprocating lawn mower to solve the problems raised in the above background art.

[0005] To achieve the above purpose, the present invention provides the following technical solutions:

The joint arm component is installed on the fixed component, the driving component is installed on the joint arm component, and the mowing component is installed at the end of the joint arm component:

[0007] The joint arm component is used to control and adjust the position and angle of the mowing component;

[0008] The fixed component is used to be fixedly installed on a skid steer loader;

[0009] The driving component is used to provide driving force for the joint arm component;

[0010] The mowing assembly is used to trim the lawns, tree branches, and forage vegetation in green belts, gardens, and farms. The mowing assembly includes a U-shaped plate, a crank, a mounting plate, a hydraulic motor, a connecting rod, a connecting plate, a knife plate, and a fixed knife. The mounting plate is installed on the U-shaped plate by bolts. The hydraulic motor is installed on one side of the mounting plate by bolts. The crank is fixedly connected to the output shaft of the hydraulic motor. The other end of the crank is rotatably connected to one end of the connecting rod.

The knife plate is fixedly connected to the U-shaped plate. The moving knife is slidably connected in the through groove of the fixed knife. The connecting plate 46 is fixedly connected to the moving knife 49.

[0011] In one embodiment, the articulated arm assembly includes a fixed frame, a first swing arm, an extension arm, a second swing arm, a stabilizing member, and an arc-shaped connecting member. One end of the first swing arm is rotatably connected to the fixed frame. The extension arm is integrally formed with the first swing arm. One end of the second swing arm is rotatably connected to the end of the extension arm. The stabilizing member is rotatably connected to the end of the second swing arm. The arc-shaped connecting member is rotatably connected to the other end of the stabilizing member. The other end of the arc-shaped connecting member is rotatably connected to the U-shaped plate. The U-shaped plate is rotatably connected to the end of the second swing arm.

[0012] In one embodiment, the driving assembly includes a first hydraulic cylinder, a second hydraulic cylinder, and a third hydraulic cylinder. The bottom end of the first hydraulic cylinder is rotatably connected to the fixed frame.

Specific implementation manner

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Embodiment:

[0034] Please refer to Figures 1 to 10 , the present invention provides a technical solution:

[0035] A reciprocating mower, comprising a fixing component, a joint arm component, a driving component, and a mowing component. The joint arm component is installed on the fixing component, the driving component is installed on the joint arm component, and the mowing component is installed at the end of the joint arm component.

[0036] The joint arm component is used to control and adjust the position and angle of the mowing component. The joint arm component adjusts the position of the mowing component through the cooperation of the swing arm and the extension arm 23, and controls the rotation of the mowing component through the arc-shaped connecting member 26 to adjust the angle;

[0037] The fixing component is used for fixedly installing on a skid steer loader. In the fixing component, the mounting bracket 11 is installed on the skid steer loader;

[0038] The driving component is used to provide driving force for the joint arm component;

[0039] The mowing assembly is used to trim the lawns, branches, and forage vegetation in green belts, gardens, and farms. The mowing assembly includes a U-shaped plate 41, a crank 42, a mounting plate 43, a hydraulic motor 44, a connecting rod 45, a connecting plate 46, a knife plate 47, and a fixed knife 48. The lengths of the two ends of the U-shaped plate 41 are different. The mounting plate 43 is installed on the short end of the U-shaped plate 41 through bolts. The hydraulic motor 44 is installed on one side of the mounting plate 43 through bolts. The hydraulic motor 44 is used to drive the knife plate 47 and the fixed knife 48 to make reciprocating movements, achieving the effect of reciprocating mowing. The crank 42 is fixedly connected to the output shaft of the hydraulic motor 44. The other end of the crank 42 is rotatably connected to one end of the connecting rod 45. The other end of the connecting rod 45 is rotatably connected to the rotating rod of the connecting plate 46. The connecting plate 46 is fixedly connected to the moving knife 49. The fixed knife 48 is installed on the knife plate 47. The knife plate 47 is fixedly connected to the U-shaped plate 41. The moving knife 49 is slidably connected to the through groove of the fixed knife 48. When the crank 42 rotates, it will drive one end of the connecting rod 45 to make a circular rotation. Since the moving knife 49 is slidably connected to the through groove of the fixed knife 48 and the sliding path of the moving knife 49 is linear, when one end of the connecting rod 45 rotates in the left semi-circle, the other end of the connecting rod 45 will push the moving knife 49 to translate. When one end of the connecting rod 45 rotates in the right semi-circle, the other end of the connecting rod 45 will pull the moving knife 49 to reset, thus achieving the reciprocating movement effect and the reciprocating mowing effect.

[0040] Further, the articulated arm assembly includes a fixed frame 21, a first swing arm 22, an extension arm 23, a second swing arm 24, a stabilizing member 25, and an arc-shaped connecting member 26. One end of the first swing arm 22 is rotatably connected to the fixed frame 21. The extension arm 23 is integrally formed with the first swing arm 22. One end of the second swing arm 24 is rotatably connected to the end of the extension arm 23. The stabilizing member 25 is rotatably connected to the end of the second swing arm 24. The arc-shaped connecting member 26 is rotatably connected to the other end of the stabilizing member 25. The other end of the arc-shaped connecting member 26 is rotatably connected to the U-shaped plate 41. The U-shaped plate 41 is rotatably connected to the end of the second swing arm 24. By adjusting the rotation angles of the first swing arm 22, the extension arm 23, and the second swing arm 24, the effect of adjusting the position of the mowing assembly at the end can be achieved.

[0041] Further, the driving assembly includes a first hydraulic cylinder 31, a second hydraulic cylinder 32, and a third hydraulic cylinder 33. The bottom end of the first hydraulic cylinder 31 is rotatably connected to the fixed frame 21, and the end of the output shaft of the first hydraulic cylinder 31 is rotatably connected to the connection point between the first swing arm 22 and the extension arm 23. The bottom end of the second hydraulic cylinder 32 is rotatably connected to the top end of the first swing arm 22, and the end of the output shaft of the second hydraulic cylinder 32 is rotatably connected to the second swing arm 24. The bottom end of the third hydraulic cylinder 33 is rotatably connected to the top of the second swing arm 24, and the end of the output shaft of the third hydraulic cylinder 33 is rotatably connected to one end of the arc-shaped connecting member 26. The first hydraulic cylinder 31 drives the first swing arm 22 and the extension arm 23 to rotate, and the second hydraulic cylinder 32 and the third hydraulic cylinder 33 drive the second swing arm 24 and the mowing assembly to rotate respectively. Among them, when the output shaft of the third hydraulic cylinder 33 expands and contracts, it will drive the other end of the arc-shaped connecting member 26 to rotate around the end of the second swing arm 24, that is, drive the mowing assembly to rotate around the end of the second swing arm 24. Both ends of the stabilizing member 25 are connected to the arc-shaped connecting member 26 and the second swing arm 24, which can control the relative positions of the arc-shaped connecting member 26 and the second swing arm 24, thereby providing a stabilizing effect for the rotation of the mowing assembly.

[0042] Further, the fixing assembly includes a hanging bracket 11 and a controller 13. The controller 13 is installed on one side of the hanging bracket 11, and the other side of the hanging bracket 11 is installed on the skid steer loader. The side of the hanging bracket 11 close to the controller 13 is fixedly connected to the fixed frame 21. The controller 13 is connected to the driving assembly through a hydraulic system. The controller 13 is used to control the first hydraulic cylinder 31, the second hydraulic cylinder 32, and the third hydraulic cylinder 33.

[0043] Further, a protective cover 12 is installed on the side of the hanging bracket 11 close to the controller 13, and the controller 13 is arranged inside the protective cover 12. The protective cover 12 is used to protect the controller 13.

[0044] Further, a plurality of fixed knives 48 are provided. The fixed knives 48 are equidistantly arranged on one side of the knife plate 47, and each fixed knife 48 is provided with two symmetrical cutting teeth. The cutting teeth can effectively cut and trim the lawn, branches, and forage vegetation in the green belt, garden, and farm.

[0045] Refer to Figures 6 - 10 , through the coordinated use of the driving assembly and the articulated arm assembly, the present invention can adjust the position of the mowing assembly and the angle of the knife plate 47.

[0046] Principle of use of the present invention: The hydraulic motor 44 drives the crank 42 to rotate, driving one end of the connecting rod 45 to make a circular motion. Since the moving knife 49 is slidably connected in the through groove of the fixed knife 48, and the sliding path of the moving knife 49 is linear, when one end of the connecting rod 45 rotates in the left semi-circle, the other end of the connecting rod 45 will push the moving knife 49 to translate. When one end of the connecting rod 45 rotates in the right semi-circle, the other end of the connecting rod 45 will pull the moving knife 49 to reset, thereby achieving a reciprocating motion effect and achieving the effect of reciprocating mowing. By adjusting the rotation angles of the first swing arm 22, the extension arm 23, and the second swing arm 24 through the drive mechanism, the effect of adjusting the position of the mowing assembly at the end can be achieved. Among them, when the output shaft of the third hydraulic cylinder 33 expands and contracts, it will drive the other end of the arc-shaped connecting piece 26 to rotate around the end of the second swing arm 24, that is, drive the mowing assembly to rotate around the end of the second swing arm 24, and adjust the angle of the cutter plate 47. Both ends of the stabilizing member 25 are connected to the arc-shaped connecting piece 26 and the second swing arm 24, which can control the relative positions of the arc-shaped connecting piece 26 and the second swing arm 24, thereby providing a stabilizing effect for the rotation of the mowing assembly.
