Fig. 2 is a structural schematic diagram of the extension type chain saw cutting device in the present invention.

Detailed ways

Sand step-type brush cutter of the present invention, its preferred specific embodiment is shown in Figure 1, comprises frame 5, walking device, and the front end of frame 5 is provided with cutting device 7. The cutting device 7 can be an extension chain saw, or other saw blades and the like.

Walking gear comprises road wheel 6 and drive wheel 2, can be that front wheel is drive wheel, also can rear wheel be drive wheel. The tire of driving wheel 2 and road wheel 6 can be to be able to adapt to walking on sandy ground and not destroy the low pressure tire of sandy ground surface, special decorative pattern is arranged.

A power machine 4 is arranged on the frame 5, and the power machine 4 is connected with the driving wheel 2 through a transmission device 3. The transmission device 3 includes a worm gear, a reduction gear, and a slope friction clutch. Driving wheel 2 is provided with differential mechanism, facilitates the turning of shrub cutter.

The rear end of frame 5 is provided with hand-held operating system 1, realizes the operation to brush cutter, comprises the operation of walking, cutting. When the hand-held operation of the machine advances to the bushes, the cutting device 7 is aimed at the bushes, and along with the movement of the machine, the saw blade or the chain saw just cut off the bushes from the roots. According to needs, the clutch can be manipulated to separate and combine the power transmitted to the driving wheels at any time, and the differential mechanism can make the rear driving wheels of the machine have different speeds when turning.

As shown in FIG. 2 , the extension-type chain saw cutting device includes a drive sprocket 11 and a guide plate 8 , and a saw chain 9 is arranged between the drive sprocket 11 and the guide plate 8 , and the saw chain 9 bypasses the edge of the guide plate 8 . The front end of the guide plate 8 can be arc-shaped, and can be a large arc plate. The edge of the guide plate 8 is provided with a groove, and the saw chain 9 can slide in the groove.

The saw chain 9 is engaged with the drive sprocket 11, and when the drive sprocket 11 rotates, the saw chain 9 is driven to run quickly along the groove on the edge of the guide plate 8, thereby achieving the purpose of fast sawing shrubs.

A tensioning device 10 is provided between the drive sprocket 11 and the guide plate 8 . The specific tensioning device 10 may include a long slot, a slide block and an adjusting lead screw. One end of the slider is a cylinder, and the other end can be a cylinder or a cube, and the middle is engaged with a lead screw and can slide in a long groove. The end of guide plate 8 has 2 elongated holes and 3 circular holes, is installed on the front end of frame 5 with bolt by elongated hole. Any one of the 3 round holes at the end of the guide plate 8 cooperates with the cylinder of the slide block, and the amount of protrusion of the guide plate 8 can be adjusted by turning the leading screw. The driving sprocket 11 is also installed on the frame 5, and when the extension of the guide plate 8 is adjusted by the tensioning device, the tension between the sprocket 11 and the guide plate 8 can be adjusted.

The left and right cutting teeth on the saw chain 9 have horizontal blades and vertical blades, which can be cut in any direction of the timber.

In the step-by-step shrub cutter for sandy land of the present invention, the protruding chain saw cutting device is a saw chain with a special structure, which has fast cutting and high productivity; the incision surface of the root of sandy bushes is smooth and has strong germination power; it is suitable for walking on sandy land , and less damage to the sandy ground surface; the structure of the whole machine is simple, the manufacturing cost is low, and it is suitable for popularization.

The above is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed in the present invention can easily think of changes or Replacement should be covered within the protection scope of the present invention.
