Technical Field

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

[0002] A weed removal device is a device or tool used to destroy or remove weeds. This device may utilize a variety of technologies and designs to suit different weed control needs and operating environments. A weed removal device typically includes a processing tool (such as a blade or rotating disk) that is controlled by an automated control mechanism, such as a mechanical, hydraulic, or photoelectric mechanism, to remove weeds. Weed removal devices are designed to remove weeds efficiently and accurately while minimizing damage to the surrounding environment.

[0003] The cutting blades of existing weeding devices are usually not equipped with protective devices. During use, the operator may accidentally touch the blade during operation, resulting in serious cutting injuries. When the blade rotates at high speed, if it hits a hard object, it may cause the blade to break, thereby affecting subsequent use, and even produce flying fragments, posing a threat to the operator and surrounding personnel. Therefore, a protective mechanism for a weeding device is proposed to solve the above problems. Utility Model Content

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] Example 1:

[0022] See also Figure 1-3 , a protective mechanism for a weeding device in this embodiment includes a mounting platform 1, a push handle 11 is provided on the left side of the mounting platform 1, a roller 12 is provided on the mounting platform 1, a transmission device 13 is provided on the top of the mounting platform 1, and the output end of the transmission device 13 is connected to the transmission belt 14, and a mounting frame 15 is provided on the right side of the mounting platform 1, and a weeding cage 16 is rotatably connected to the mounting frame 15, and a plurality of cutting components 2 for weeding are provided on the weeding cage 16, and the transmission belt 14 is connected to the weeding cage 16 for transmission; a top protective plate 17 for protection is provided on the top of the mounting frame 15, and a cleaning component 3 for cleaning the cutting component 2 is provided on the top of the top protective plate 17; the cutting component 2 includes a cutting blade 21 for weeding, and a connecting plate 22 is provided on the top of the cutting blade 21, and a plurality of protective columns 23 for protection are provided on the connecting plate 22, and a fixing member 24 for connecting with the cutting blade 21 is also provided on the connecting plate 22.

[0023] As a preferred technical solution in this embodiment: in actual use, when the staff needs to weed, they can control the transmission device 13 to drive the transmission belt 14 to make the weeding cage 16 rotate. During the rotation of the weeding cage 16, the cutting blade 21 can be driven to rotate, thereby achieving the weeding effect. At this time, the staff can drive the mounting platform 1 as a whole to move by pushing the push handle 11, thereby achieving the effect of weeding over a large area; when the weeding cage 16 drives the cutting blade 21 to achieve the weeding effect, the protective column 23 can effectively protect the cutting blade 21. During the rotation process, the weeds will contact the cutting blade 21 through the gap between the protective columns 23, so that the cutting blade 21 can isolate the weeds. When encountering solid hard objects, the protective column 23 can shovel the hard objects away, thereby avoiding direct contact between the hard objects and the cutting blade 21, effectively avoiding the collapse of the cutting blade 21, and effectively ensuring its safety during use.

[0024] The technical effects brought about by the above embodiment are: by providing the connecting plate 22 and the protective column 23, the cutting blade 21 can be effectively protected during use, and the cutting blade 21 can be effectively prevented from directly contacting hard objects during the weeding process, resulting in collapse affecting subsequent use and splashing of fragments that endanger the staff.

[0025] Example 2:

[0026] See also Figure 4 To achieve the desired cleaning effect on the cutting assembly 2, the cleaning assembly 3 in this embodiment includes a mounting plate 31, which is fixedly connected to the top protective plate 17. Two guide sleeves 32 are provided at the top of the mounting plate 31 for guidance, and adjustment rods 33 are slidably connected within each guide sleeve 32. A cleaning brush head 34 for cleaning the cutting assembly 2 is fixedly connected to the bottom of each adjustment rod 33. A connecting rod 35 is fixedly connected to the top of each adjustment rod 33. A threaded ring 36 is provided at the top of the connecting rod 35, and a threaded rod 37 is threadedly connected to the inner thread of the threaded ring 36. The bottom of the threaded rod 37 is rotatably connected to the mounting plate 31, and an adjustment handle 38 is fixedly connected to the top of the threaded rod 37 for easy adjustment.

[0027] As a preferred technical solution in this embodiment: after weeding is completed, when the staff needs to clean the cutting assembly 2, they can first control the adjusting handle 38 to drive the threaded rod 37 to rotate, and during the rotation of the threaded rod 37, a downward displacement effect can be generated. During the downward displacement of the threaded rod 37, the connecting rod 35 and the adjusting rod 33 can be driven to move downward, and during the downward displacement of the adjusting rod 33, the cleaning brush head 34 can be driven to fit the cutting assembly 2. Then the staff can control the transmission device 13 to drive the weeding cage 16 to rotate in the opposite direction, and during the reverse rotation of the weeding cage 16, multiple cutting assemblies 2 can be driven to contact the cleaning brush head 34, so that the dirt and weeds attached to the cutting assembly 2 can be cleaned well by the cleaning brush head 34.

[0028] The technical effects brought about by the above embodiment are: by providing a cleaning brush head 34, the surface of the cutting component 2 can be effectively treated during use, thereby avoiding the need for staff to manually clean it after weeding is completed; by providing a threaded rod 37, the height of the cleaning brush head 34 can be flexibly adjusted during use, thereby avoiding interference with the cutting component 2 when the cutting component 2 is weeding.

[0029] The working principle of the above embodiment is:

[0030] 1. In actual use, when the staff needs to weed, they can control the transmission device 13 to drive the transmission belt 14 to make the weeding cage 16 rotate. During the rotation of the weeding cage 16, the cutting blade 21 can be driven to rotate, thereby achieving the weeding effect. At this time, the staff can drive the mounting platform 1 as a whole to move by pushing the push handle 11, thereby achieving the effect of weeding over a large area; when the weeding cage 16 drives the cutting blade 21 to achieve the weeding effect, the protective column 23 can effectively protect the cutting blade 21. During the rotation process, the weeds will contact the cutting blade 21 through the gap between the protective columns 23, so that the cutting blade 21 can isolate the weeds. When encountering solid hard objects, the protective column 23 can achieve the effect of shoveling the hard objects away, thereby avoiding direct contact between the hard objects and the cutting blade 21, effectively avoiding the occurrence of collapse of the cutting blade 21, and effectively ensuring its safety during use.

[0031] 2. After weeding is completed, when the staff needs to clean the cutting assembly 2, they can first control the adjusting handle 38 to drive the threaded rod 37 to rotate, and during the rotation of the threaded rod 37, a downward displacement effect can be generated. During the downward displacement of the threaded rod 37, the connecting rod 35 and the adjusting rod 33 can be driven to move downward. During the downward displacement of the adjusting rod 33, the cleaning brush head 34 can be driven to fit the cutting assembly 2. Then, the staff can control the transmission device 13 to drive the weeding cage 16 to rotate in the opposite direction. During the reverse rotation of the weeding cage 16, multiple cutting assemblies 2 can be driven to contact the cleaning brush head 34, so that the dirt and weeds attached to the cutting assembly 2 can be removed by the cleaning brush head 34 to achieve a good cleaning effect.
