The invention provides an ecological efficient weeding device for agriculture and forestry.

In the embodiment of the invention, as shown in fig. 1 to 5, the ecological agriculture and forestry efficient weeding device comprises a machine body 1, a support rod 2 and a weeding assembly 3.

Specifically, the machine body 1 may be a hand-held machine body or a backpack machine body, a control system (not shown) and an energy supply system (not shown) are integrated in the machine body 1, the control system is used for controlling the opening, closing, output efficiency and the like of the weeding device, and the energy supply system can supply energy for a driving component, the control system and the like, and in general, the energy supply system uses a storage battery as a core. Of course, the energy supply system may also use a diesel generator as a core.

One end of the supporting rod 2 is provided with a handle 21, and the other end is provided with a weeding assembly 3. The handle 21 is provided with control keys (not shown) electrically connected with the control system, wherein the control keys comprise, but are not limited to, a start-up key of the weeding device, a rotation speed adjusting key of the weeding assembly 3 and a form control key of the weeding assembly 3. By means of the support bar 2, it is possible to facilitate the user to operate the weeding assembly 3 for weeding.

The weeding assembly 3 includes a bracket 31, a first motor 32, a driving wheel 33, a first driven wheel 34, and a saw wire 35. Wherein, the bracket 31 is arranged at the other end of the supporting rod 2, the first motor 32 is arranged on the bracket 31, the driving wheel 33 and the first driven wheel 34 are rotatably connected to the bracket 31, and the driving wheel 33 and the first driven wheel 34 are arranged on the bracket 31 at intervals. The first motor 32 is used for driving the driving wheel 33. The saw wire 35 is sleeved on the driving wheel 33 and the first driven wheel 34. Specifically, when the first motor 32 drives the driving wheel 33 to rotate, the saw wire 35 can rotate at a high speed under the driving of the driving wheel 33 and the first driven wheel 34 to cut weeds. The sawing wire 35 may be a metal wire, a plastic wire, a fiber wire, a composite wire, etc. Illustratively, the desired saw wire 35 may be prepared by adding metal particles, diamond particles, etc. to the fiber or plastic. This is where the spacing of the primary wheel 33 from the primary driven wheel 34 can be considered the mowing width of the herbicidal assembly 3.

In this embodiment, the first driven wheel 34 may also be close to or far from the driving wheel 33 to change the distance between the driving wheel 33 and the first driven wheel 34. It will be appreciated that as the spacing of the primary wheel 33 from the primary driven wheel 34 is varied, the mowing width of the herbicidal assembly 3 is varied. Thus, the operator can reduce the mowing width of the weeding assembly 3 to remove weeds in narrow areas, or increase the mowing width of the weeding assembly 3 to weed in wide areas. Therefore, the ecological agriculture and forestry high-efficiency weeding device can adapt to different environments and realize high-efficiency weeding.

Therefore, compared with the weeding device with fixed mowing width, the ecological agriculture and forestry high-efficiency weeding device has the advantages of being strong in environment adaptability and high in weeding efficiency.

Specifically, in the present embodiment, the bracket 31 includes a first mounting bar 311 and a second mounting bar 312. The first mounting rod 311 is disposed at the other end of the support rod 2, the driving wheel 33 is rotatably connected to one end of the first mounting rod 311, the second mounting rod 312 is rotatably connected to the other end of the first mounting rod 311, the first driven wheel 34 is rotatably connected to the second mounting rod 312, and the second mounting rod 312 can rotate relative to the first mounting rod 311, so that the first driven wheel 34 is close to or far from the driving wheel 33.

Specifically, the driving wheel 33 is disposed on the first mounting rod 311, the first driven wheel 34 is disposed on the second mounting rod 312, and the distance between the first driven wheel 34 and the driving wheel 33 is changed by adjusting the rotation angle of the second mounting rod 312 relative to the first mounting rod 311. In this case, when the second mounting lever 312 is rotated, the width of the stand 31 can be adjusted so that the width of the stand 31 is changed according to the mowing width, in addition to the adjustment of the interval between the first driven wheel 34 and the driving wheel 33. In this way, the stand 31 is spread in a wide area and narrowed in a narrow area, and the environmental adaptability of the herbicidal assembly 3 is further improved.

Further, two ends of the second mounting rod 312 are respectively provided with a mounting portion 312a, and the first driven wheel 34 and the second driven wheel 37 are respectively connected to the two mounting portions 312a in a rotating manner. By installing the first driven wheel 34 and the second driven wheel 37 on the two installation portions 312a respectively, the distance between the saw wire 35 and the second installation rod 312 can be increased, so that weeds can be prevented from winding between the second installation rod 312 and the saw wire 35 during weeding, and the stability of the weeding assembly 3 in operation can be improved.

Specifically, when the second mounting bar 312 is rotated to a position perpendicular to the first mounting bar 311, the driving wheel 33, the first driven wheel 34, and the second driven wheel 37 form an equilateral triangle. Thus, on one hand, the structural stability of the weeding assembly 3 is improved, on the other hand, the weeding assembly 3 can be used for comprehensively cutting off weeds, and the usability of the weeding assembly 3 is improved. Of course, the design of the present application is not limited thereto, and in other embodiments, the driving wheel 33, the first driven wheel 34, and the second driven wheel 37 may also form an isosceles triangle, a right triangle, or the like.

Specifically, the elastic telescopic rod 361 includes a fixed rod and a movable rod, a slot (not shown) is disposed in the fixed rod, an elastic member (not shown) is disposed in the slot, the movable rod is inserted in the slot and is subject to the elastic force of the elastic member, the movable rod partially extends out of the slot, and the tension wheel 362 is rotatably connected to one end of the movable rod extending out of the fixed rod. Since the tension pulley 362 abuts against the saw wire 35, the elastic force of the lever elastic member can be utilized to tension the saw wire 35.

Alternatively, the elastic member may be a spring or a shrapnel.

Further, the elastic telescopic rod 361 is provided to the second mounting rod 312, and the elastic telescopic rod 361 extends from the second driven wheel 37 in the direction of the first driven wheel 34.

Secondly, make the flexible pole 361 extend from the second follow driving wheel 37 to the direction of first follow driving wheel 34 for the contained angle setting that is the acute angle between flexible pole 361 and the second installation pole 312, so, both be favorable to improving the structural stability of flexible pole 361 and second installation pole 312, be favorable to take-up pulley 362 tensioning saw line 35.

Specifically, when the second mounting bar 312 is rotated to a position perpendicular to the first mounting bar 311, the elastic telescopic bar 361 and the tension pulley 362 are located at a side of the second mounting bar 312 facing the driving wheel 33. In this way, the tensioning member 36 is located inside the triangle formed by the driving wheel 33, the first driven wheel 34 and the second driven wheel 37, so that the tensioning member 36 can be prevented from interfering with the cutting of the saw wire 35.
