Description

Technical Field

[0001] This utility model relates to the field of orchard weed control technology, and in particular to an orchard weed removal device. Background Technology

[0002] The main methods of weed control in orchards include chemical weeding, manual weeding, mechanical weeding, covering with weed-proof film, and using grass to suppress weeds. Among these, mechanical weeding, which involves using mechanical equipment such as lawnmowers or mini-tillers to remove weeds, is the most widely used.

[0003] According to Chinese Patent Publication No. CN222148147U, a weeding device for orchards is proposed. By adjusting the fixing mechanism, the working state of the cutting disc can be adjusted to allow for reasonable removal of weeds based on their condition. This means either simply removing the weeds or using the pulverized weeds as fertilizer for the fruit trees to promote their growth. The combination of the cutting disc and the pulverizing disc can quickly and effectively remove all weeds and also loosen the soil around the fruit trees, which is beneficial to their growth. The diversion plate can concentrate the cut weeds, making it easier to remove the roots and clear the weeds.

[0004] The application document states that the working state of the cutting disc can be adjusted according to the working environment. However, in actual use, the terrain of the orchard may vary, such as low-lying areas or gentle slopes. In addition, for orchards with raised beds, the height of the raised beds varies. When removing weeds, the cutting disc may come into excessive contact with the ground, which may damage the cutting disc. Therefore, an orchard weed removal device is proposed to solve the above problems. Utility Model Content

[0023] like Figure 1-3 As shown, the present invention proposes an orchard weed removal device, which includes a frame 1 and a weed removal structure 2 disposed inside the frame 1.

[0024] The weeding structure 2 includes a horizontal plate 21 fixedly installed inside the frame 1. A U-shaped frame 22 is provided at the bottom of the horizontal plate 21. A first cylinder 23 extending to the bottom of the horizontal plate 21 is fixedly installed at the top of the horizontal plate 21. The piston rod of the first cylinder 23 is fixedly connected to the top of the U-shaped frame 22. Two guide rods 24 extending to the top of the horizontal plate 21 are fixedly installed at the top of the U-shaped frame 22. Both guide rods 24 are slidably connected to the horizontal plate 21. A fixed box 25 is provided inside the U-shaped frame 22. The front and back of the fixed box 25 are fixedly installed with... Rotating rods 26, with opposite sides of the two rotating rods 26 respectively rotatably connected to the front and rear side walls of the inner cavity of the U-shaped frame 22. A fixing plate 27 is fixedly installed at the bottom of the fixing box 25. Two connecting shafts 28 extending to the bottom of the fixing plate 27 are rotatably connected to the inner top wall of the fixing box 25. A drive assembly 29 is provided inside the fixing box 25. The output end of the drive assembly 29 is connected to the connecting shafts 28. A cutting disc 210 is fixedly installed at the bottom of each of the two connecting shafts 28. An angle adjustment assembly 211 is provided on the left side of the U-shaped frame 22.

[0025] In this invention, the frame 1 can be used to install the weeding structure 2, which can then be used to weed the orchard. During the weeding process, the drive assembly 29 can drive the two connecting shafts 28 to rotate, which in turn drive the two cutting discs 210 to rotate. Simultaneously, before or during weeding, if the terrain changes, the first cylinder 23 can be activated. The piston rod of the first cylinder 23 will drive the U-shaped frame 22 to move upwards or downwards. The U-shaped frame 22 will then drive the two rotating rods 26 and the fixed box 25 to move upwards or downwards. The fixed box 25 will then drive the two connecting shafts 28 and the two cutting discs 210 to move upwards or downwards, thereby adjusting the distance between the two cutting discs 210 and the ground. This allows the cutting discs 210 to adjust the weeding depth according to the orchard terrain, effectively preventing the cutting discs 210 from contacting the ground during weeding and thus avoiding damage. This also allows the cutting discs 210 to adapt to different weeding needs.

[0026] In addition, the U-shaped frame 22 can be guided by two guide rods 24 to ensure the stability of the U-shaped frame 22 during movement, thereby ensuring the stability of the cutting disc 210 when it moves upward or downward.

[0027] In addition, when weeding fresh or withered grass, the angle adjustment component 211 can drive the fixed box 25 to rotate under the action of the two rotating rods 26. The fixed box 25 will drive the drive component 29, the connecting shaft 28 and the cutting disc 210 to rotate, thereby adjusting the angle of the cutting disc 210 in various directions, so as to facilitate the cutting of fresh or withered grass by the cutting disc 210, thereby achieving the effect of effective weeding in the orchard.

[0028] In an optional embodiment, the drive assembly 29 includes a dual-head servo motor 2901 fixedly mounted on the top of the fixed plate 27. The output shafts of the two dual-head servo motors 2901 are each connected to a rotating shaft 2902 via a coupling. A driving bevel gear 2903 is fixedly mounted on the opposite side of the two rotating shafts 2902. A driven bevel gear 2904 is fixedly mounted on the outer side of the two connecting shafts 28. The two driving bevel gears 2903 mesh with the two driven bevel gears 2904 respectively.

[0029] It should be noted that when weeding is required, by activating the dual-head servo motor 2901, the two output shafts of the dual-head servo motor 2901 will drive the two rotating shafts 2902 to rotate, the two rotating shafts 2902 will drive the two active bevel gears 2903 to rotate, the two active bevel gears 2903 will drive the two meshing driven bevel gears 2904 to rotate, and the two driven bevel gears 2904 will drive the two connecting shafts 28 to rotate. The rotation of the two connecting shafts 28 will drive the rotation of the two cutting discs 210, thereby achieving the purpose of cutting weeds through the rotation of the two cutting discs 210.

[0030] In an optional embodiment, the angle adjustment assembly 211 includes a top plate 2111 fixedly installed on the left side of the U-shaped frame 22, a bottom plate 2112 fixedly installed on the left side of the fixing box 25, a second cylinder 2113 hinged to the bottom of the top plate 2111 by a pin, and the piston rod of the second cylinder 2113 hinged to the top of the bottom plate 2112 by a pin.

[0031] It should be noted that when the weeding angle of the cutting disc 210 needs to be adjusted, the second cylinder 2113 is directly activated. The length of the second cylinder 2113 will be extended. Under the hinge action of the top plate 2111 and the bottom plate 2112, the piston rod of the second cylinder 2113 will push the fixed box 25. At this time, under the action of the two rotating rods 26, the fixed box 25 will rotate, thereby causing the fixed box 25 to drive the drive assembly 29, the connecting shaft 28 and the cutting disc 210 to rotate, so as to achieve the purpose of adjusting the angle of the cutting disc 210. When adjusting the cutting angle of the cutting disc 210, the cutting disc 210 can be in an inclined or vertical state, so that the cutting disc 210 can better adapt to the removal of various weeds.

[0032] In an optional embodiment, two connecting blocks 3 are fixedly installed on the front and back of the frame 1. The end of the connecting block 3 away from the frame 1 is rotatably connected to a walking wheel 4. A V-shaped baffle 5 is fixedly installed at the bottom of the frame 1. The bottom horizontal position of the V-shaped baffle 5 is higher than the bottom horizontal position of the walking wheel 4.

[0033] It should be noted that the connecting block 3 and the traveling wheel 4 allow the frame 1 to move on the orchard ground, while the V-shaped baffle 5 can shield the cut weeds, preventing sap or grass clippings from splashing onto the workers during the cutting process. At the same time, during the movement of the frame 1, the V-shaped baffle 5 can push the cut weeds, causing them to move towards the front and back of the frame 1, thus preventing the weeds from interfering with the movement of the left traveling wheel 4.

[0034] In an optional embodiment, a push handle 6 is fixedly installed on the top left side of the frame 1, a vertical plate 7 is fixedly installed on the top left side of the frame 1, and a controller 8 is provided on the top of the vertical plate 7.

[0035] It should be noted that the frame 1 can be pushed by the push handle 6, and together with the connecting block 3 and the walking wheel 4, the staff can push the entire weed removal device to move. The first cylinder 23, the dual-head servo motor 2901 and the second cylinder 2113 are all electrically connected to the controller 8. The controller 8 can control the first cylinder 23, the dual-head servo motor 2901 and the second cylinder 2113.

[0036] Working principle:

[0037] In use, the orchard weed removal device is operated by pushing the handle 6, which, in conjunction with the connecting block 3 and the walking wheels 4, allows the entire device to be moved. When it reaches the location where weeding is required, the first cylinder 23 is activated, which drives the cutting disc 210 to move up or down, thereby adjusting the distance between the cutting disc 210 and the ground. Once the distance is adjusted, the dual-head servo motor 2901 is activated, which drives the two cutting discs 210 to rotate. The rotation of the two cutting discs 210 then cuts and removes the weeds. For different types of weeds, the second cylinder 2113 is activated, which drives the two cutting discs 210 to rotate, thereby adjusting the cutting angle of the two cutting discs 210 so that they can cut and remove different types of weeds.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
