Description

Technical Field

[0001] This utility model relates to the field of drive shaft cleaning technology, and in particular to a drive shaft cleaning device for lawnmowers. Background Technology

[0002] As a type of machinery widely used in landscaping, farmland management, and home lawn maintenance, the stability and reliability of lawn mowers directly affect their operational efficiency and quality. The drive shaft, as a key transmission component of the lawn mower, bears the important responsibility of transmitting the engine's power to the cutting components, ensuring that the cutting blades can operate efficiently at the appropriate speed and torque.

[0003] During the operation of a lawnmower, the drive shaft needs to withstand significant torque, vibration, and complex loads under various working conditions. Furthermore, since lawnmowers are typically used outdoors, the drive shaft inevitably comes into contact with dust, dirt, grass clippings, moisture, and various chemicals such as pesticides and fertilizers. These impurities and corrosive substances gradually adhere to the surface of the drive shaft and may even seep into its internal structure, such as bearings and gears. Over time, the accumulation of dirt on the drive shaft surface increases friction during transmission, leading to greater power transmission losses. Utility Model Content

[0005] A lawnmower drive shaft cleaning device includes a cleaning frame and a support frame installed on the upper surface of the cleaning frame. The inner cavity of the support frame is equipped with a fixing mechanism for fixing the drive shaft. A support plate is installed on the upper end of the cleaning frame. A rotating frame is rotatably connected to the inner wall of the upper end of the support plate. A cleaning mechanism for cleaning the drive shaft is threadedly connected to the inner wall of the rotating frame.

[0006] As an improvement to the above technical solution, the fixing mechanism includes a spring, a telescopic rod, and a fixing plate. The ends of the spring that are far apart from each other are fixedly connected to the ends of the support frame that are far apart from each other in the inner cavity.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0021] Please see Figure 1-6 This utility model provides a technical solution: a lawnmower drive shaft cleaning device, including a cleaning frame 1 and a support frame 2 installed on the upper end of the cleaning frame 1. The inner cavity of the support frame 2 is equipped with a fixing mechanism 3 for fixing the drive shaft. A support plate 4 is installed on the upper end of the cleaning frame 1. A rotating frame 5 is rotatably connected to the inner wall of the upper end of the support plate 4. A cleaning mechanism 6 for cleaning the drive shaft is threadedly connected to the inner wall of the rotating frame 5.

[0022] The drive shaft is fixed by the cooperation of the fixing mechanism 3 and the support frame 2. Then, the drive shaft is cleaned by the rotating frame 5 and the cleaning mechanism 6, thereby cleaning the dust, dirt and grass clippings adhering to the upper end of the drive shaft, preventing dirt from contaminating the drive shaft, preventing dirt from adhering to the drive shaft, and preventing the increase of friction when the drive shaft rotates.

[0023] Specifically, the fixing mechanism 3 includes a spring 31, a telescopic rod 32, and a fixing plate 33. The ends of the spring 31 that are far apart from each other are fixedly connected to the ends of the support frame 2 that are far apart from each other. The outer wall of the telescopic rod 32 is engaged with the inner cavity of the support frame 2 and fixedly connected to the ends of the spring 31 that are close to each other. The ends of the fixing plate 33 that are far apart from each other are fixedly connected to the ends of the telescopic rod 32 that are close to each other.

[0024] The spring force of the spring 31 causes the telescopic rods 32 to move closer together, which in turn drives the fixing plates 33 to move closer together. The fixing plates 33 move closer together and fix the transmission shaft, thereby assisting the cleaning mechanism 6.

[0025] Specifically, the cleaning mechanism 6 includes a screw 64 and a cleaning plate 65. The outer wall of the screw 64 is threadedly connected to the inner wall of the rotating frame 5. The front end of the cleaning plate 65 is rotatably connected to the outer wall of the rear end of the screw 64, and the lower end of the cleaning plate 65 overlaps with the lower end face of the inner cavity of the rotating frame 5.

[0026] The rotation of screw 64 causes cleaning plate 65 to move to one side, so that the soft brush at the upper end of cleaning plate 65 comes into contact with the drive shaft. At this time, rotating frame 5 rotates, driving screw 64 and cleaning plate 65 to rotate. Cleaning plate 65 rotates and cleans drive shaft.

[0027] Specifically, the cleaning mechanism 6 includes a first gear 61, a motor 62, and a second gear 63. The inner wall of the first gear 61 is fixedly connected to the outer wall of the rotating frame 5. The lower end of the motor 62 is fixedly connected to the inner wall of the support plate 4. The lower end of the second gear 63 is fixedly connected to the output end of the motor 62, and the outer wall of the second gear 63 meshes with the outer wall of the first gear 61.

[0028] like Figure 2 As shown, the rotation of motor 62 drives the second gear 63 to rotate, the rotation of the second gear 63 drives the first gear 61 to rotate, the rotation of the first gear 61 drives the rotating frame 5 to rotate, and the rotation of the rotating frame 5 drives the screw 64 and the cleaning plate 65 to rotate, thereby cleaning the drive shaft.

[0029] Specifically, the cleaning mechanism 6 includes a water pump 66 and a pipe 67. One end of the water pump 66 is fixedly connected to the front end of the cleaning plate 65, and the rear end of the water pump 66 is connected to the front end of the cleaning plate 65. The rear end of the pipe 67 is connected to the front end of the water pump 66, and the outer wall of the pipe 67 penetrates the inner wall of the rotating frame 5 and extends into the inner cavity of the cleaning frame 1.

[0030] like Figure 6 When the water pump 66 is started, the cleaning fluid in the inner cavity of the cleaning frame 1 enters the water pump 66 through the pipe 67, and then enters the cleaning plate 65 through the water pump 66. It is then sprayed onto the surface of the drive shaft through the holes opened in the cleaning plate 65, and softens the dirt on the drive surface in advance.

[0031] Specifically, a soft brush for cleaning the drive shaft is installed at the rear end of the cleaning plate 65, and a drainage hole is provided at the rear end of the cleaning plate 65.

[0032] like Figure 6 As shown, the cleaning soft brush installed on the cleaning plate 65 brushes the dirt on the surface of the drive shaft, and the cleaning plate 65 has holes so that the cleaning fluid can soften the dirt on the surface of the drive shaft through the holes.

[0033] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
