Description

Technical Field

[0001] The utility model relates to the technical field of weeders, in particular to a walking mechanism for weeders. Background Art

[0002] The lawn mower is mainly composed of three parts: a walking frame, a power mechanism and a weeding blade barrel. Generally speaking, the walking frame and the weeding blade barrel are driven by the power mechanism. Taking into account the working environment of the lawn mower, when the power mechanism transmits power to the walking frame, it will be interfered with by weeds, and additional protective measures are required to prevent weeds from being involved, such as protective covers or protective nets. In addition, the power transmission path is long and the transmission structure is complex, which ultimately leads to the lawn mower being heavy and expensive, which is not conducive to market demand and consumer operation. There is an urgent need for a walking mechanism suitable for a lawn mower that is simple in structure and not affected by weeds. Utility Model Content

[0003] The purpose of the utility model is to provide a running mechanism for a weeder, so as to solve the problem of lack of a running mechanism which is suitable for the weeder and has a simple structure and is not affected by weeds.

[0004] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0005] A walking mechanism for a lawn mower, comprising a walking wheel, a motor, a reduction gearbox, a bushing, a flange and an end cover. The motor and the reduction gearbox are both mounted on a frame of the lawn mower, the power output end of the motor is connected to the power input end of the reduction gearbox, the bushing is mounted on the reduction gearbox, the power output shaft of the reduction gearbox is located within the bushing, the end cover is mounted on the outer end of the power output shaft of the reduction gearbox, the flange is connected to the end cover, and the hub portion of the walking wheel is connected to the flange.

[0006] A further technical solution is: the flange is located on the inner side of the running wheel, and the end cover is located on the outer side of the running wheel.

[0007] A further technical solution is that the flange and the end cover are both located outside the running wheel.

[0008] A further technical solution is that a bearing is provided between the flange and the shaft sleeve.

[0009] A further technical solution is that a stepped fitting surface is provided between the flange and the shaft sleeve.

[0010] A further technical solution is: an oil filling hole is provided on the shaft sleeve, and the oil filling hole is connected to the liquid outlet end of the oiler.

[0011] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0012] The utility model proposes a walking mechanism for a weeder, which does not share a power mechanism with other mechanisms. The motor and the walking wheel cooperate separately, and the motor directly provides power to the walking wheel. Steering is achieved by relying on the differential speed of the two motors, and the normal walking of the weeder is achieved at the same speed, which greatly shortens the power transmission path and has a simple structure. Moreover, the mutual cooperation of the shaft sleeve, the flange and the end cover can prevent weeds from being entangled while driving the walking wheel. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] Example 1:

[0026] This embodiment Figure 1 、 Figure 2 、 Figure 3 and Figure 4 As shown, a walking mechanism for a lawn mower includes a walking wheel 1, a motor 2, a reduction gearbox 3, a bushing 4, a flange 5 and an end cover 6. The motor 2 and the reduction gearbox 3 are both installed on the frame of the lawn mower. The power output end of the motor 2 is connected to the power input end of the reduction gearbox 3. The bushing 4 is installed on the reduction gearbox 3. The power output shaft of the reduction gearbox 3 is located in the bushing 4. The end cover 6 is installed on the outer end of the power output shaft of the reduction gearbox 3. The flange 5 is connected to the end cover 6. The hub part of the walking wheel 1 is connected to the flange 5.

[0027] The running wheels 1 are symmetrically and rotatably mounted on the frame of the mower. The motor 2 is activated, reducing speed through the reduction gearbox 3. The output shaft of the reduction gearbox 3 is protected by a bushing 4 to prevent it from becoming entangled in weeds during rotation. Furthermore, the running mechanism features a short power transmission path, a simple structure, and ease of operation. The outer end of the output shaft of the reduction gearbox 3 is connected to an end cap 6. A flange 5 connects to the end cap 6 and the running wheels 1, thereby driving the rotation of the running wheels 1.

[0028] It is worth noting that the steering is achieved by relying on the differential speed of the two coaxial motors 2, and the normal movement of the lawn mower is achieved at the same speed.

[0029] In some cases, such as when the vehicle frame is light or the travel speed requirement is not high, the reduction gearbox 3 can be eliminated and the motor 2 is directly connected to the travel wheel 1 .

[0030] Preferably, the flange 5 is located on the inner side of the running wheel 1 , and the end cover 6 is located on the outer side of the running wheel 1 .

[0031] The flange 5 is inside to shorten the power transmission path;

[0032] The end cover 6 is outside, which facilitates the disassembly and assembly of the components themselves and the disassembly and assembly of the running wheels;

[0033] The flange 5 is included, which can also beautify the appearance of the machine.

[0034] Preferably, the flange 5 and the end cover 6 are both located outside the running wheel 1 .

[0035] It is convenient for disassembly and assembly of flange 5 and end cover 6.

[0036] Preferably, a bearing is provided between the flange 5 and the shaft sleeve 4 .

[0037] The flange 5 can rotate on the sleeve 4, and the rotational friction is reduced by the bearing.

[0038] Preferably, if Figure 5 As shown, a stepped mating surface is provided between the flange 5 and the shaft sleeve 4 .

[0039] The stepped mating surface facilitates the installation between the flange 5 and the shaft sleeve 4 and plays a limiting role.

[0040] Preferably, the shaft sleeve 4 is provided with an oil filling hole, which is communicated with the liquid outlet end of the oil injector.

[0041] The external oiler provides lubricating oil between the shaft sleeve 4 and the output shaft of the reduction gearbox 3 or between the shaft sleeve 4 and the output shaft of the motor through the oil filling hole.

[0042] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments, or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
