[0029] In conventional lawn mowers, turning the steering wheel changes the magnitude and direction of power through a power transmission device, which then transmits it to a drive unit, which then folds the front and rear frames. Four-wheel drive tractors rotate around the intersection of the extended axes of the front and rear wheels. This steering method limits the mower's steering angle, resulting in limited operational flexibility during turns and U-turns, and poor operating efficiency.

[0030] In order to solve the above problems, the present application proposes a lawn mower. The embodiments of the present application are further described below in conjunction with the accompanying drawings.

[0031] Reference Figures 1 to 3 The present application provides a lawn mower, comprising: a frame 110, a traction mechanism, a front drive steering mechanism, an auxiliary steering mechanism, a driving mechanism, a hydraulic drive mechanism and a mowing device 114; the frame 110 comprises a front frame, a middle frame and a rear frame, which are connected in sequence, and the front frame, the middle frame and the rear frame are formed in one piece, the traction mechanism is connected to the front frame, and the mowing device 114 is connected to the traction mechanism; the front drive steering mechanism comprises two front wheels 120, which are respectively arranged on both sides of the front frame, the hydraulic drive mechanism comprises a hydraulic oil tank, two first oil pumps and two hydraulic motor drivers 121, the first oil pump, the hydraulic motor driver 121 and the front wheels 120 correspond one to one, the hydraulic oil tank and the two first oil pumps are all arranged on the front frame, and the front wheels 12 0 is connected to the corresponding hydraulic motor driver 121, the hydraulic motor driver 121 is connected to the corresponding first oil pump, and the two first oil pumps are respectively connected to the hydraulic oil tank; the driving mechanism includes a cab 111, a direction controller and a 360° steering controller, the direction controller and the 360° steering controller are both arranged in the cab 111, and the direction controller and the 360° steering controller are respectively connected to the two first oil pumps; the auxiliary steering mechanism includes a rear wheel support frame 131, two wheel buffer limiters and two auxiliary steering wheels 130, the rear wheel support frame 131 is arranged at the bottom of the rear end frame, the two wheel buffer limiters are symmetrically arranged at both ends of the rear wheel support frame 131, the wheel buffer limiters correspond one-to-one to the auxiliary steering wheels 130, and the auxiliary steering wheels 130 are connected to the corresponding wheel buffer limiters.

[0032] It should be noted that the steering controller includes a steering wheel and a steering sensor. When the operator controls the steering wheel to perform a steering operation, the steering sensor generates a first steering signal and a second steering signal based on the steering operation, and sends the first steering signal and the second steering signal to the first oil pump corresponding to the left front wheel and the right front wheel respectively;

[0033] For example, when the lawn mower needs to turn left, the direction controller transmits a first steering signal to the first oil pump corresponding to the left front wheel, and the first oil pump outputs a first hydraulic energy to the corresponding hydraulic motor driver 121 according to the first steering signal. The hydraulic motor driver 121 converts the first hydraulic energy into mechanical energy and controls the left front wheel to travel at a first speed through the mechanical energy; at the same time, the direction controller transmits a second steering signal to the first oil pump corresponding to the right front wheel, and the first oil pump outputs a second hydraulic energy to the corresponding hydraulic motor driver 121 according to the second steering signal. The hydraulic motor driver 121 converts the second hydraulic energy into mechanical energy and controls the right front wheel to travel at a second speed through the mechanical energy; wherein, the amount of oil supplied by the first oil pump to the left front wheel is less than the amount of oil supplied by the first oil pump to the right front wheel, and the first speed is less than the second speed, thereby forming a speed differential between the left front wheel and the right front wheel to achieve left steering.

[0034] For example, when the lawn mower is to make a large-angle turn, the operator presses the button corresponding to the 360° steering controller, and the 360° steering controller sends a third steering signal to the first oil pump corresponding to the left front wheel, and sends a fourth steering signal to the first oil pump corresponding to the left front wheel. The first oil pump controls the hydraulic oil tank to provide a third hydraulic energy to the hydraulic motor driver 121 corresponding to the left front wheel according to the corresponding third steering signal, so that the hydraulic motor driver 121 controls its own gear motor to reverse through the third hydraulic energy, thereby causing the corresponding left front wheel to move backward; at the same time, the 360° steering controller sends a fourth steering signal to the first oil pump corresponding to the right front wheel, and sends a fourth steering signal to the first oil pump corresponding to the right front wheel. The first oil pump controls the hydraulic oil tank to provide a fourth hydraulic energy to the hydraulic motor driver 121 corresponding to the right front wheel according to the corresponding fourth steering signal, so that the hydraulic motor driver 121 controls its own gear motor to rotate forward through the fourth hydraulic energy, thereby causing the corresponding right front wheel to move forward; the right front wheel moves forward and the left front wheel moves backward, thereby realizing a 360° rotation of the lawn mower.

[0035] It should be noted that the hydraulic oil tank is connected to the two first oil pumps via oil pipes, and the first oil pumps are also connected to the corresponding hydraulic motor drivers 121 via oil pipes.

[0036] In the present application, a traction mechanism is provided in front of the vehicle frame 110, and the mowing device 114 is connected to the vehicle frame 110 through the traction mechanism. The two front wheels 120 are provided on both sides of the front end of the vehicle frame 110, and the two auxiliary steering wheels 130 are provided on both sides of the rear end of the vehicle frame 110. The direction controller is used to send a first steering signal to the first oil pump corresponding to the left front wheel of the two front wheels 120 when the lawn mower turns left or right, and send a second steering signal to the first oil pump corresponding to the right front wheel of the two front wheels 120. The first oil pump is used to control the amount of hydraulic pressure provided by the hydraulic oil tank to the hydraulic motor driver 121 according to the corresponding first steering signal or the second steering signal. The hydraulic motor driver 121 is used to control the speed of the corresponding front wheel 120 according to the corresponding first steering signal or the second steering signal. By controlling the speed of one of the front wheels 120 to be slow and the speed of the other front wheel 120 to be fast, a differential speed is formed, thereby realizing the control of turning the lawn mower left or right; the 360° steering controller is used to control the rotation speed of the corresponding front wheel 120 according to the corresponding first steering signal or the second steering signal. When the lawn mower makes a large-angle turn, a third steering signal is sent to the first oil pump corresponding to the left front wheel, and a fourth steering signal is sent to the first oil pump corresponding to the right front wheel. The first oil pump is used to control the amount of hydraulic pressure provided by the hydraulic oil tank to the hydraulic motor driver 121 according to the corresponding third steering signal or the fourth steering signal. The hydraulic motor driver 121 is used to control the travel direction and speed of the corresponding front wheel 120 according to the corresponding third steering signal or the fourth steering signal. The two auxiliary steering wheels 130 arranged at the rear of the frame 110 are passive steering wheels. When the front wheels 120 turn left or right or make a large-angle turn, the auxiliary steering wheels 130 also follow suit and perform passive steering. The auxiliary steering can follow the front wheels 120 to make a 360° turn, thereby improving the steering flexibility of the lawn mower. By providing a wheel buffer limiter to buffer and limit the corresponding auxiliary steering wheel 130, the auxiliary steering wheel 130 is prevented from turning too flexibly. The mowing device 114 is used for mowing tasks in orchards, lawns or fields. Through this setting, the present application can achieve more precise steering and U-turn functions, improve the steering ability of the lawn mower, and thus improve the rotation flexibility of the lawn mower, making the lawn mower suitable for mowing operations in complex grassland environments in open grasslands in the wild.

[0037] Reference Figure 2 It can be understood that the traction mechanism includes a first support frame 113 and two traction connecting frames 112. The first support frame 113 is arranged at the bottom of the front end frame, one end of the two traction connecting frames 112 is arranged at both ends of the first support frame 113, and the other ends of the two traction connecting frames 112 are connected to the mowing device 114.

[0038] It should be noted that, by providing two traction connecting frames 112 connected to the mowing device 114 , the connection between the vehicle frame 110 and the front mowing device 114 is made stronger and more stable.

[0039] It can be understood that the mowing device 114 includes a mower frame, a mowing disc and two suspension connectors, the hydraulic drive mechanism includes a second oil pump and a second hydraulic motor driver 121, the second oil pump is arranged on the front end frame, the second oil pump is respectively connected to the hydraulic oil tank and the second hydraulic motor driver 121, the second hydraulic motor driver 121 is arranged inside the mower frame, the mowing disc is arranged at the bottom of the mower frame, the two suspension connectors are arranged side by side at one end of the mower frame close to the frame 110, the traction connecting frame 112 corresponds one to one to the suspension connector, and the end of the traction connecting frame 112 away from the first support frame 113 is connected to the corresponding suspension connector.

[0040] In some embodiments, the mowing disc includes three cutter discs, which are staggered and the rotating surfaces of the three cutter discs are tangent to each other in sequence. The centers of the three cutter discs form an obtuse triangle. This not only prevents the sharp cutter heads on the cutter discs from colliding with each other when the second hydraulic motor driver 121 drives the high-speed rotation, thereby causing damage to the cutter discs and affecting the service life of the lawn mower, but also further expands the mowing area of ​​the cutter disc, so that the lawn mower can clear the weeds under the body at one time without any residue when passing through, thereby greatly improving the work efficiency of the mowing operation.

[0041] Reference Figure 2 It can be understood that the front-drive steering mechanism also includes a front wheel support frame 122, which is arranged at the bottom of the front end frame, and the front wheel support frame 122 and the first support frame 113 are arranged side by side and spaced apart, and the first support frame 113 is connected to the front wheel support frame 122, and the two front wheels 120 are respectively connected to the two ends of the front wheel support frame 122.

[0042] It should be noted that, by providing the front wheel support frame 122 , the two front wheels 120 are connected to the front end frame via the front wheel support frame 122 .

[0043] It can be understood that the driving mechanism includes a driving seat, a footrest and an operating table. The driving seat, footrest and operating table are all located in the cab 111. The footrest is located between the driving seat and the operating table. The operating table is located on the front end frame. The direction controller and the 360° steering controller are both located on the operating table.

[0044] In some embodiments, armrest operating levers are provided on both sides of the operating console. The operator controls the direction controller, 360° steering controller and the armrest operating levers on both sides on the driving seat 130 to control the direction of travel of the lawn mower.

[0045] It should be noted that the steering controller includes a steering wheel and a steering sensor. When the operator controls the steering wheel to perform steering operations, the steering sensor generates a first steering signal and a second steering signal according to the steering operation, and sends the first steering signal and the second steering signal to the first oil pump corresponding to the left front wheel and the right front wheel respectively.

[0046] Reference Figure 3 It can be understood that the wheel buffer limiter includes a buffer frosting piece assembly 132, a side plate assembly 133, a first connecting shaft, a second connecting shaft 135 and a limiting sleeve 134. The first connecting shaft is sequentially inserted into the buffer frosting piece assembly 132 and the side plate assembly 133. The second connecting shaft 135 passes through the shaft hole in the middle of the auxiliary steering wheel 130, and both ends of the second connecting shaft 135 are exposed from the shaft hole. The side plate assembly 133 is respectively connected to the two ends of the second connecting shaft 135. The limiting sleeve 134 is sleeved on the first connecting shaft, and the rear wheel support frame 131 is connected to the side wall of the limiting sleeve 134.

[0047] It should be noted that the auxiliary steering wheel 130 is an auxiliary universal wheel, and its surface is frosted by a buffering frosting sheet assembly 132 to increase the friction between the contact surfaces so that the static friction between the contact surfaces is sufficient to appropriately limit the flexibility of the auxiliary steering wheel 130, thereby buffering and limiting the corresponding auxiliary steering wheel 130 to prevent the auxiliary steering wheel 130 from turning too flexibly.

[0048] It is understandable that the wheel buffer limiter further includes a connecting member, one end of which is connected to the side wall of the rear end frame, and the other end of which is connected to the limiting sleeve 134 .

[0049] In some embodiments, the connecting member is a connecting plate, and the rear end frame and the limiting sleeve 134 are connected together through the connecting plate to improve the stability of the connection between the wheel buffer limiter and the frame 110.
