Description

Technical Field

[0001] This utility model relates to the field of agricultural machinery and equipment technology, and in particular to a dual-shaft weeder. Background Technology

[0002] A lawnmower is a mechanical tool used for trimming lawns, vegetation, etc. It comes in diesel and gasoline engine versions and consists of a cutter head, engine, wheels, drive mechanism, blades, handle, and controls. The high-speed rotation of the engine greatly increases the output speed of the blades, thus saving lawnmower workers' time and reducing manpower. Existing lawnmowers are mainly divided into single-shaft and twin-shaft lawnmowers. Compared to single-shaft lawnmowers, twin-shaft lawnmowers, with their two rotating cutters, remove weeds more thoroughly, resulting in a neater and more aesthetically pleasing lawn.

[0003] The weeding machine described in announcement number CN221532161U includes: a base; a drive motor, which is fixedly mounted on the base, with its output shaft fixedly connected to a connecting column, and the other end of the connecting column fixedly connected to a bevel gear; a protective cover, with mounting blocks fixedly connected to both ends of the protective cover, the mounting blocks being fixedly mounted on the base by positioning bolts; a material blocking assembly, which is located at the bottom of the base and is used to intercept hard objects such as stones in the field; a weeding mechanism, which is located inside the base and is used to remove weeds from the field; and a moving assembly, which is located at the bottom of the base.

[0004] Based on the above technical features, the problem is that in the existing technology, hard materials such as stones that can easily damage the blades tend to accumulate in front of the material blocking component, which affects the normal movement of the weeder, makes subsequent weeding operations inconvenient, and results in poor weeding efficiency.

[0005] Therefore, it is necessary to solve the above problems with a dual-shaft weeding machine. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides, for example Figures 1 to 4 The illustrated dual-shaft weed cutter includes a vehicle body 1, with a handle at the rear end and wheels mounted on the bottom for easy movement.

[0021] A bracket 2 is fixedly installed on the top of the vehicle body 1, and a motor 3 is fixedly mounted on the bracket 2. A vertically oriented cutter shaft 4 is rotatably mounted on the bottom of the vehicle body 1, with the top end of the cutter shaft 4 extending upward through the vehicle body 1. The output shaft of the motor 3 is coaxially and fixedly connected to the cutter shaft 4, and a weeding blade 5 is fixedly mounted on the bottom end of the cutter shaft 4.

[0022] The weeding blade 5 includes multiple blades, which are evenly distributed around the circumference of the blade shaft 4. Each blade is arranged both horizontally and radially along the blade shaft 4. Each blade is fixedly connected to the blade shaft 4.

[0023] Each blade has multiple rake teeth fixedly installed at its bottom, and these rake teeth are evenly distributed at the bottom of each blade.

[0024] A stop block 14 and a pusher assembly are provided at the bottom front end of the vehicle body 1. The stop block 14 is fixedly connected to the vehicle body 1, and the pusher assembly is located in front of the stop block 14. A groove is provided on the front side of the stop block 14 in the horizontal direction. The groove has an arc-shaped cross section and the groove opening faces forward.

[0025] Specifically, the feeding assembly includes a pusher block 13 and two helical blades 12. Two horizontal and coaxially opposed rotating shafts are rotatably mounted on the front bottom of the vehicle body 1, and one helical blade 12 is fixedly mounted on each rotating shaft. Each helical blade 12 is arranged circumferentially along the rotating shaft. Both helical blades 12 are rotatably mounted in grooves.

[0026] Two rotating shafts are symmetrically distributed on both sides of the push block 13 and are rotatably connected to the push block 13. Two support plates 15 are fixedly installed at the bottom of the vehicle body 1, and the push block 13 is located between the two support plates 15. A rotating shaft is horizontally placed between each of the two support plates 15 and the push block 13, and the end of each rotating shaft away from the push block 13 is rotatably connected to the corresponding support plate 15.

[0027] The front end of push block 13 is V-shaped.

[0028] The output shaft of motor 3 is connected to two rotating shafts via a transmission assembly to drive the two rotating shafts to rotate.

[0029] Specifically, the transmission assembly includes a drive shaft 9, which extends vertically through the vehicle body 1 and is rotatably connected to the vehicle body 1. The output shaft of the motor 3 is connected to the drive shaft 9 via a first linkage to drive the drive shaft 9 to rotate.

[0030] Specifically, the first linkage includes a first pulley 6 and a second pulley 7. The first pulley 6 is fixedly sleeved on the output shaft of the motor 3, and the second pulley 7 is fixedly sleeved on the top end of the transmission shaft 9. The first pulley 6 and the second pulley 7 are drivenly connected within the same belt 8.

[0031] An installation compartment is provided inside the push block 13, and a second linkage is installed inside the installation compartment. The drive shaft 9 is connected to the two rotating shafts through the second linkage to drive the two rotating shafts to rotate.

[0032] Specifically, the second linkage includes a first bevel gear 10 and two second bevel gears 11. The drive shaft 9 and the two rotating shafts all pass into the mounting compartment. The first bevel gear 10 is coaxially and fixedly connected to the drive shaft 9, and each rotating shaft is coaxially and fixedly connected to one second bevel gear 11. The first bevel gear 10 meshes with the two second bevel gears 11.

[0033] Working principle: When using this dual-shaft weed cutter for weeding operations, push the handle on the vehicle body 1 to move the vehicle body 1. In this embodiment, the wheels can be driven by existing drive motors to improve the automation level of this dual-shaft weed cutter. The above technology is prior art and will not be described in detail here.

[0034] At the same time, motor 3 is started, and the output shaft of motor 3 drives the cutter shaft 4 and the first pulley 6 to rotate. The first pulley 6 drives the second pulley 7 to rotate through the belt 8, and the second pulley 7 drives the transmission shaft 9 to rotate.

[0035] When the blade shaft 4 rotates, it drives the weeding blade 5 to rotate. The blade of the weeding blade 5 cuts the weeds, and at the same time, the rake teeth on the blade break up the fallen weeds.

[0036] When the drive shaft 9 rotates, it drives the first bevel gear 10 to rotate, and the first bevel gear 10 drives the two second bevel gears 11 to rotate. The two second bevel gears 11 drive the corresponding rotating shafts to rotate, and the two rotating shafts drive the corresponding spiral blades 12 to rotate.

[0037] As the vehicle body 1 moves forward, the V-shaped block at the front of the pusher 13 pushes hard materials such as stones in the middle to both sides. As the vehicle body 1 moves forward, hard materials such as stones on the moving path remain in the groove on the front side of the stop block 14. At this time, in conjunction with the rotation of the two spiral blades 12, the two spiral blades 12 push the hard materials such as stones away from the stop block 14 in a direction away from the pusher 13, so as to prevent the hard materials such as stones from accumulating. The pushed-away hard materials such as stones are located on both sides of the vehicle body 1 and do not affect the weeding operation of the weeding blades 5.

[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
