[0029] The following is combined with Figure 1-5 The utility model is described in further detail.

[0030] The present application embodiment discloses a lawn mower, referring to Figure 1 and Figure 2 , including a body 1, a cantilever 2 and a suspension bracket 3. The suspension bracket 3 is in a U-shaped configuration as a whole. The suspension bracket 3 includes a connecting portion 31 and support portions 32 provided on both sides of the connecting portion 31. One end of the cantilever 2 is connected to one of the support portions 32 through a buffer 21, and the other end of the cantilever 2 is hinged to the body 1. An active suspension 4 cooperating with a tractor implement is rotatably connected to the support portion 32 provided with the buffer 21. An active rotating shaft 41 for the active suspension 4 to rotate is fixedly provided on the side wall of the support portion 32 away from the connecting portion 31. A reset elastic member for driving the active suspension 4 to rotate towards the support portion 32 is provided on the support portion 32. The reset elastic member can be a torsion spring or a tension spring. In the embodiment of the present application, the reset elastic member is a reset tension spring 42. One end of the reset tension spring 42 is fixed to the end of the active suspension 4 away from the active rotating shaft 41, and the other end of the reset tension spring 42 is fixed to the support portion 32. The active suspension 4 can move during use, so as to maintain the attitude and buffering of the overall installation of the suspension bracket 3 on the tractor implement. Through the setting of the reset tension spring 42, it is convenient for the active suspension 4 to return to its original position.

[0031] Refer to Figure 1 and Figure 3 , on the side walls of the cantilever 2 and the suspension bracket 3 close to the ground, a supporting wheel assembly 5 is provided. The supporting wheel assembly 5 includes a connecting bracket 51 and a supporting wheel 52 rotatably provided on the connecting bracket 51. When the mower is in an idle state, the end of the supporting wheel 52 away from the connecting bracket 51 contacts the ground, so as to facilitate the movement of the heavy machinery and improve the transfer efficiency of the heavy machinery under the effect of saving labor costs.

[0032] Refer to Figure 1 , Figure 3 and Figure 4 , on the cantilever 2 and the suspension bracket 3, an installation pipe 53 for installing the supporting wheel assembly 5 is provided. The installation pipe 53 can be fixed to the cantilever 2 or the suspension bracket 3 by gluing or welding. The installation pipe 53 includes an installation through hole 531 adapted to the connecting bracket 51. In addition, a fixing member for fixing the connecting bracket 51 is provided on the installation pipe 53. After the connecting bracket 51 is embedded in the installation through hole 531, the connecting bracket 51 is fixed to the installation pipe 53 through the fixing member, realizing the installation of the supporting wheel assembly 5. Since the installation through hole 531 is adapted to the connecting bracket 51, the stability of the movement of the heavy machinery is ensured to a certain extent.

[0033] Refer to Figure 4A placement tube 54 for storing the support wheel assembly 5 is fixedly provided on the side wall of the suspension bracket 3 away from the ground. The placement tube 54 is arranged at the end of the connecting part 31 away from the buffer 21. The placement tube 54 can be fixed to the suspension bracket 3 by gluing or welding. The placement tube 54 includes a placement through hole 541 adapted to the connecting bracket 51. In the actual placement process, the support wheel 52 is located at the end of the connecting bracket 51 away from the ground. The connecting bracket 51 is fixed to the placement tube 54 through a fixing part. When the lawn mower is hooked to the tractor for operation, the support wheel assembly 5 can be moved from the mounting tube 53 to the placement tube 54, which makes it easy to store the support wheel assembly 5 while making it less likely to affect the normal use of the lawn mower.

[0034] Reference Figure 4 The fixing parts include a quick-pull pin 55. The connecting bracket 51, the mounting tube 53 and the placement tube 54 are all provided with a quick-pull through hole that cooperates with the quick-pull pin 55. The quick-pull pin 55 enables the support wheel assembly 5 to be fixed to the mounting tube 53 or the placement tube 54, which facilitates the installation and disassembly of the support wheel assembly 5 and improves the disassembly efficiency of the support wheel assembly 5 to a certain extent.

[0035] Reference Figure 4 and Figure 5 The machine body 1 includes a housing 11 and a blade shaft 12. The rear center portion of the housing 11 has a sunken design, which effectively ensures the enclosure strength and mechanical properties of the housing 11. The blade shaft 12 is located within the housing 11 and is rotatably connected to the housing 11 at both ends. A rotating mechanism 13 for driving the blade shaft 12 to rotate is provided at one end of the housing 11. In the embodiment of the present application, the rotating mechanism 13 includes a rotating motor 131 and a reducer 132. The output shaft of the rotating mechanism 13 is coaxially fixed to the input shaft of the reducer 132, and the output shaft of the reducer 132 is coaxially fixed to the blade shaft 12. The mowing blades 121 are evenly arranged on the cutter shaft 12, and the inner wall of the hood 11 is provided with multiple rows of fixed knives 111 that cooperate with the mowing blades 121. In the embodiment of the present application, there are two rows of fixed knives 111, and the fixed knives 111 are channel steel type. The single row of fixed knives 111 is arranged along the length direction of the cutter shaft 12. The fixed knives 111 can cooperate with the mowing blades 121 to complete the grass chopping. The setting of the double-row array welded channel steel type fixed knives 111 effectively improves the grass chopping effect.

[0036] Reference Figure 4 and Figure 5 The hood 11 is also rotatably connected to a roller 14. Through the setting of the roller 14, the cut grass can be flattened, so that the cut grass is not easy to fly around and affect the normal operation of the lawn mower. The grass cutting, chopping and throwing operations can be completed by following the rotating tangent of the knife shaft 12. The grass is thrown in front of the roller 14, and the throwing space is reasonable.

[0037] Reference Figure 4 and Figure 5A rubber baffle 15 is also connected to the hood 11. The rubber baffle 15 is located on the side of the hood 11 away from the suspension bracket 3. The rubber baffle 15 can effectively prevent flying stones from being thrown out during the mowing operation. At the same time, its soft characteristics also ensure that when some wet grass is accumulated at the rear, it will not cause blockage.

[0038] Reference Figure 5 The rubber baffle 15 is fixed to the hood 11 through a baffle pressure plate 16. The setting of the baffle pressure plate 16 provides protection for the rubber baffle 15, effectively extending the service life of the rubber baffle 15. The baffle pressure plate 16 is in contact with the end face of the rubber baffle 15 away from the hood 11. The rubber baffle 15 is fixed to the hood 11 through a fixing bolt 17. The rubber baffle 15, the baffle pressure plate 16 and the hood 11 are all provided with a fixing through hole for the fixing bolt 17 to pass through. The fixing bolt 17 is provided with a fixing nut 171 that cooperates with the bolt thread. The fixing bolt 17 cooperates with the fixing nut 171 to fix the rubber baffle 15 to the hood 11.

[0039] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
