[0031] The existing tree root machine includes large automatic tree root machine and manual push tree root machine. The large automatic tree root machine is large in size, while the manual push tree root machine is small in size and more flexible to use, especially for narrow operating space. The manual push tree root machine relies entirely on manual pushing to move. The user pushes the tree root machine for a long time, which is labor-intensive and affects work efficiency.

[0032] In view of the above problems, the embodiment of the utility model provides a new type of tree root machine, which can realize the movement of the tree root machine by combining manpower and a driving device, thereby reducing the labor intensity of the user to a certain extent, and the use is flexible and convenient.

[0033] Combine the following Figure 1-Figure 4 The technical solution provided by the utility model is described in more detail.

[0034] Embodiment 1:

[0035] The new tree root machine provided by the utility model comprises a frame 1 with a push handle 2, a driven walking wheel 3 rotatably connected to the frame 1, and a driving wheel 4, wherein: a driving device is arranged on the frame 1 and is transmission-connected to the driving wheel 4, for driving the driving wheel 4 to rotate; the ground contacting surface of the driving wheel 4 and the ground contacting surface of the driven walking wheel 3 are not arranged in the same plane, and the position of the driving wheel 4 is higher than the driven walking wheel 3 when the push handle 2 is in the raised state, and the driving wheel 4 and the driven walking wheel 3 touch the ground together when the push handle 2 is in the lowered state, thereby driving the frame 1 to move.

[0036] The push handle 2 is used for manual holding. When the position of the driving wheel 4 is higher than the driven walking wheel 3 when the push handle 2 is in the raised state, the user can push the push handle 2 by hand to move the tree root machine.

[0037] Figure 1 The middle is a schematic diagram of a state when the user lifts the push handle 2 and the driving wheel 4 is higher than the driven running wheel 3 and off the ground. When the user puts down the push handle 2, the rear part of the frame 1 descends, the driving wheel 4 and the driven running wheel 3 touch the ground together, and the driving wheel 4 drives the frame 1 to move, thereby reducing the labor intensity of the user.

[0038] The stump crusher of the present embodiment has both driven wheels 3 and driving wheels 4 on its frame 1. When the push handle 2 lifts the stump crusher to crush the stump, the driving wheel 4 is higher than the driven wheels 3 and leaves the ground. The user pushes the driven wheels 3 by hand, and the driving wheel 4 does not affect the crushing work of the blade 7 of the stump crusher.

[0039] When the stump crusher is not performing crushing work and needs to be moved, the handle is put down, and the driving wheel 4 and the driven walking wheel 3 can touch the ground together. At this time, the driving wheel 4 drives the stump crusher to move, and the driven walking wheel 3 follows the rotation, which can assist manpower and reduce the labor intensity of the user.

[0040] When steering is required, the handle can be lifted, the driving wheel 4 is off the ground, and the tree root machine can be easily pushed to turn by manpower.

[0041] As an alternative embodiment, see Figure 1 and Figure 2 As shown, there are at least two driven wheels 3, which are located on the side of the driving wheel 4 away from the push handle 2; in this embodiment, there are two driven wheels 3, and the driving wheel 4 and the driven wheels 3 are arranged in a triangular structure.

[0042] That is, the two driven wheels 3 and the driving wheel 4 are respectively located at the three end points of an equilateral triangle, which can improve stability. When the driving wheel 4 and the driven wheel 3 are on the ground together, the driving wheel 4 can drive the tree root machine to move stably.

[0043] As an alternative embodiment, see Figure 2 and Figure 3 As shown, the driving device and the driving wheel 4 are driven by a chain or a belt. Specifically, the driving device can be a brushless motor, see Figure 3 As shown, the output end of the brushless motor is connected to a driving sprocket 51, and the driving wheel 4 is connected to a driven sprocket 52. The driving sprocket 51 and the driven sprocket 52 are driven by a chain. When the brushless motor is working, it can drive the wheel 4 to rotate.

[0044] Prior art rooters include a cutting disc which is driven by a gasoline engine on the rooter.

[0045] The driving device in this embodiment can be powered by an external power supply alone, or, as an optional implementation, the tree root machine in this embodiment includes a battery, and the battery is electrically connected to the gasoline engine 6 and the driving device of the tree root machine, and the battery is used to power the driving device.

[0046] In this embodiment, when the gasoline engine 6 is running, the generator coil charges the battery (this is an existing mature technology), and the battery supplies power to the drive device (brushless motor), thereby ensuring the normal operation of the drive device (brushless motor), and further ensuring that the drive wheel 4 can work stably.

[0047] See also Figure 1 As shown, a switch 13 is provided at the upper end of the push handle 2, and the switch 13 is electrically connected to the drive device and is used to control the drive device to start or shut down. When the user holds the push handle 2, the drive device and the drive wheel 4 can be started or shut down, and the operation is convenient.

[0048] As an alternative embodiment, see Figure 1 and Figure 4 As shown, the tree root machine also includes a shaft (not marked) and a cutter disc 7, the shaft is rotatably connected to the frame 1, the cutter disc 7 is fixed to the shaft, and the gasoline engine 6 is used to drive the shaft to rotate. Figure 4 As shown, in this embodiment, the number of the cutter discs 7 on the same shaft is more than two ( Figure 4 The number of the middle cutter discs 7 is two, but not limited to this number, and the cutter discs 7 are arranged at intervals along the length direction of the shaft.

[0049] The method of driving the shaft to rotate by the gasoline engine 6 is an existing mature technology. The above structure is provided with more than two cutter discs 7, which can greatly improve the efficiency of crushing tree stumps.

[0050] At the initial start-up of the cutter disc 7, if the cutter disc 7 touches the ground, it is easy to cause the cutter disc 7 to be difficult to start and the cutter disc 7 to be easily damaged.

[0051] For the above questions, see Figure 1 and Figure 4 As shown, the tree root machine also includes a leg 8, which is rotatably connected to the frame 1. For details, see Figure 4 As shown, the legs 8 are rotatably connected to the frame 1 via the rotating shaft 1010. When the legs 8 are supported on the ground, there is a distance between the cutter disc 7 and the ground.

[0052] When the cutter disc 7 is not working, or before the cutter disc 7 is started, the legs 8 are used to support the cutter disc 7 on the ground so that the cutter disc 7 is located above the ground, which can prevent the cutter disc 7 from starting up and facilitate the smooth start of the cutter disc 7.

[0053] As an alternative embodiment, see Figure 4 As shown, the tree root machine also includes an elastic reset member 9, one end of the elastic reset member 9 is connected to the frame 1, and the other end is connected to the support leg 8. When the support leg 8 is supported on the ground, the elastic reset member 9 is in a stretched state.

[0054] The elastic reset member 9 may be a tension spring. Specifically, the elastic reset member 9 may be connected to the frame 1 and the leg 8 via a bolt and nut assembly.

[0055] When the cutter disc 7 is located above the ground, the legs 8 are rotated and supported on the ground; when the cutter disc 7 is required to perform crushing work, the legs 8 are rotated around the rotating shaft 10, the legs 8 are no longer supported on the ground, and the cutter disc 7 can contact the stump.

[0056] The specific implementation method of “rotating the supporting leg 8 around the rotating shaft 10 ” is, for example, the user holds the supporting leg 8 and rotates it, or applies an external force to the supporting leg 8 with the foot to rotate the supporting leg 8 , and so on.

[0057] The elastic restoring member 9 can utilize the elastic restoring force to pull the supporting leg 8 to rotate when the user holds the supporting leg 8 to rotate, or when the user applies an external force to the supporting leg 8 with the foot, thereby reducing the force applied by the user and being easy to use.

[0058] As an alternative embodiment, see Figure 4 As shown, a baffle 11 is also provided on the frame 1, and the baffle 11 is located on the side of the cutter disc 7. The baffle 11 can prevent the debris from splashing from the side when the cutter disc 7 crushes the stump to a certain extent, thereby protecting the user and improving the safety performance of use.

[0059] As an alternative embodiment, see Figure 1 and Figure 4 As shown, a protective cover 12 is also provided on the frame 1 , and the protective cover 12 is arranged outside the cutter disc 7 .

[0060] The protective cover 12 is covered on the upper part of the cutter disc 7, which can prevent the debris from splashing upward when the cutter disc 7 crushes the stump to a certain extent, thereby protecting the user and improving the safety performance of use.

[0061] The tree root machine of this embodiment can be used in the following three situations:

[0062] When the stump crusher is crushing the stumps, the push handle 2 is lifted, the driving wheel 4 is higher than the driven running wheel 3 and leaves the ground, the user pushes the push handle 2 by hand, the driven running wheel 3 rotates under the human power, so that the stump crusher can crush the stumps while moving, and the driving wheel 4 does not affect the crushing work of the knife disc 7 of the stump crusher.

[0063] When the stump crusher is not performing crushing work and needs to be moved, the handle is put down, and the driving wheel 4 and the driven walking wheel 3 touch the ground together. At this time, the driving wheel 4 drives the stump crusher to move in a straight line, and the driven walking wheel 3 follows the rotation, which can assist manpower and reduce the labor intensity of the user.

[0064] When steering is required, the handle can be lifted, the driving wheel 4 is off the ground, and the tree root machine can be easily pushed to turn by manpower.

[0065] In the description of this specification, specific features, structures or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.

[0066] In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the utility model.
