Description

Technical Field

[0001] The present invention relates to the technical field of weeding devices, and in particular to a machine weeding device. Background Art

[0002] Weeding is an important link in agricultural production, horticultural management, and environmental protection. The main purpose is to reduce the negative impact of weeds on crops, plants, and the ecosystem. There are many types of existing weeding devices. In flat areas, large machines can be used for weeding, while in areas with many obstacles such as trees, small machines are needed for weeding. Moreover, in areas where the trees are intertwined and complex, manual control of the machine's direction is required to better carry out weeding.

[0003] Publication No. CN221010854U discloses an orchard weeding device. Through the setting of the second hydraulic cylinder and the second hydraulic telescopic rod, the height of the driving motor can be adjusted, and then weeds of various heights can be processed. In addition, according to the setting of the first hydraulic cylinder and the first hydraulic telescopic rod, the height of the weeding combing component can be adjusted, which facilitates the combing of weeds and the cutting treatment of weeds in the orchard.

[0004] During the use of the above-mentioned existing weeding device, the height and angle of the handle and its control rod cannot be adjusted as needed. In some planting areas, the heights of the tree branches are different. When using the weeding device to weed between trees, when encountering some blocking tree trunks, sometimes the operator needs to bend down to pass through, and sometimes the operator needs to pass through sideways. When the operator bends down or sideways, since the height and angle of the handle and the control rod cannot be adjusted according to the operator's body posture changes, it is difficult for the operator to better control the weeding device. Moreover, when the weeding device is weeding, it will generate vibrations, and the handle and control rod of the above device lack corresponding shock-absorbing measures, causing certain discomfort to the operator's hands during long-term work. Summary of the Invention

[0018] From the above technical solutions, it can be seen that the present application has the following beneficial effects:

[0019] 1: When encountering an obstacle in the form of a tree branch blocking the weeding path and the operator needs to walk sideways, pull the first towing rope to drive the moving column, connecting block, and the second end face gear ring to move upward. When the second end face gear ring moves upward to separate from the first end face gear ring, the control rod can be rotated left and right to drive the U-shaped plate to rotate. When the U-shaped plate rotates, it drives the connecting cylinder to rotate, enabling the angle of the control rod to be adjusted as needed, allowing the operator to hold the control rod sideways while the device can continue to move forward.

[0020] 2: When encountering an obstacle in the form of a tree branch blocking the weeding path and the operator needs to bend down to walk, pull the second towing rope to move the toothed plate into the inner cavity, separating the toothed plate from the gear. At this time, the control rod can be rotated downward to drive the rectangular plate to drive the connecting plate to rotate. At this time, the annular sleeve rotates outside the connecting shaft, thereby lowering the height of the control rod to facilitate the operator to bend down and pass under the tree trunk.

[0021] 3: During the weeding process, the vibration of the engine will drive the housing and the support column to vibrate up and down. When the support column moves upward, it will drive the first limit rod to move accordingly. At this time, the first limit rod moves downward in the first stroke groove and compresses the first elastic member. At this time, the first elastic member can play a shock-absorbing role. And when the support column moves upward, it will drive the piston to move upward in the cylindrical barrel, causing the piston to discharge the air in the cylindrical barrel from the first air hole. At this time, the air in the cylindrical barrel will blow up the columnar foam. At this time, the columnar foam no longer blocks the third air hole, that is, the air in the cylindrical barrel is discharged from the third air hole and the second air hole. And when the compressed first elastic member needs to return to its original state, at this time, the columnar foam will move downward under the action of gravity, causing the columnar foam to block the third air hole. At this time, the outside air only enters the cylindrical barrel from the second air hole, making the exhaust speed of the cylindrical barrel greater than the intake speed, so that the speed of the first elastic member returning to its original state slows down, avoiding the up and down jitter of the control rod caused by the rapid rebound after the first elastic member is compressed, and thus achieving the purpose of shock absorption.

[0039] Refer to Figures 1-11 :

[0040] For an embodiment of the present invention, a machine weeding device is provided, which includes a main body unit 100 and a control unit 200. The main body unit 100 includes a housing 101. A cylinder 103 is fixed on the housing 101. An engine 104 is installed on the cylinder 103. A circular groove 102 is formed in the housing 101, and the circular groove 102 communicates with the cylinder 103. A first rotating shaft 105 is rotatably connected in the cylinder 103. One end of the output shaft of the engine 104 is fixed to one end of the first rotating shaft 105. A blade 106 is installed at the end of the first rotating shaft 105 away from the engine 104. Ear plates 107 are fixed at the four corners of the bottom of the housing 101. A second rotating shaft 108 is rotatably connected between two corresponding ear plates 107. Rollers 109 are fixed at both ends of the second rotating shaft 108. The control unit 200 includes a support column 201. The support column 201 is fixed on the housing 101. A cylindrical barrel 202 is arranged above the support column 201. A cylindrical rod 203 is fixed at the top of the cylindrical barrel 202. A connecting barrel 204 is rotatably connected at the top of the cylindrical rod 203. A U-shaped plate 205 is fixed at the top of the connecting barrel 204. Two control rods 206 are arranged on one side of the U-shaped plate 205. A primary adjustment assembly for adjusting the angle of the control rods 206 is arranged on the cylindrical rod 203. A secondary adjustment assembly for adjusting the height of the control rods 206 is arranged in the U-shaped plate 205. A shock absorption assembly for reducing the vibration of the control rods 206 is arranged in the cylindrical barrel 202.

[0041] Among them, the shock absorption assembly includes a plurality of first stroke grooves 207 formed in the cylindrical barrel 202. A plurality of first limiting rods 209 are fixed on the outer side of the support column 201. A through groove 210 is formed in the first limiting rod 209. A guide rod 208 is fixed in the first stroke groove 207. The guide rod 208 penetrates through the through groove 210. The first limiting rod 209 is slidably fitted outside the guide rod 208. A first elastic member 211 is sleeved outside the guide rod 208. One end of the first elastic member 211 abuts against the first limiting rod 209, and the other end of the first elastic member 211 abuts against the inner wall of the first stroke groove 207. A piston 240 is fixed on the top of the support column 201. The piston 240 is hermetically and slidably fitted in the cylindrical barrel 202. A plurality of conduits 212 are fixed on the top of the cylindrical barrel 202. A plurality of first air holes 213 are formed in the top of the cylindrical barrel 202, and the plurality of first air holes 213 are respectively communicated with the corresponding conduits 212. An annular baffle 214 is fixed on the top of the conduit 212. A cylindrical foam 215 is slidably connected in the conduit 212. A second air hole 216 is formed in the middle of the cylindrical foam 215. The diameter of the cylindrical foam 215 is larger than the diameters of the first air hole 213 and the annular baffle 214. The diameter of the second air hole 216 is one-fourth of the diameter of the first air hole 213. A plurality of third air holes 217 are formed at equal intervals along the radial direction of the bottom of the conduit 212.

[0042] During use, start the engine 104 to drive the first rotating shaft 105 to rotate. When the first rotating shaft 105 rotates, it drives the blade 106 to rotate. At this time, the blade 106 can carry out weeding. During the weeding process, the vibration of the engine 104 will drive the housing 101 to vibrate accordingly. When the housing 101 vibrates, it will drive the support column 201 to vibrate up and down. When the support column 201 moves upward, it will drive the first limiting rod 209 to move accordingly. At this time, the first limiting rod 209 moves downward in the first stroke groove 207 and compresses the first elastic member 211. At this time, the first elastic member 211 can play a role in shock absorption. It should be noted that the first elastic member 211 can use devices such as springs. When the support column 201 moves upward, it will drive the piston 240 to move upward in the cylindrical barrel 202, so that the piston 240 discharges the air in the cylindrical barrel 202 from the first air hole 213. At this time, the air in the cylindrical barrel 202 will blow up the cylindrical foam 215. At this time, the cylindrical foam 215 no longer blocks the third air hole 217, that is, the air in the cylindrical barrel 202 is discharged from the third air hole 217 and the second air hole 216. When the compressed first elastic member 211 needs to return to its original state, at this time, the cylindrical foam 215 will move downward under the action of gravity, so that the cylindrical foam 215 blocks the third air hole 217. At this time, the outside air only enters the cylindrical barrel 202 from the second air hole 216, so that the exhaust speed of the cylindrical barrel 202 is greater than the intake speed, thereby slowing down the speed of the first elastic member 211 returning to its original state, avoiding the up and down shaking of the control rod 206 caused by the rapid rebound of the first elastic member 211 after compression, and thus achieving the purpose of shock absorption.

[0043] In addition, the first-level adjustment component includes an annular plate 218 fixed to the top of the cylindrical rod 203. A first end-face gear ring 219 is fixed to the top of the annular plate 218. A moving column 221 is slidably connected inside the connecting cylinder 204. A plurality of second stroke grooves 223 are formed inside the connecting cylinder 204. A plurality of connecting blocks 222 are fixed to the outside of the moving column 221. The connecting blocks 222 are slidably fitted inside the corresponding second stroke grooves 223. A second end-face gear ring 220 is arranged outside the connecting cylinder 204, and the second end-face gear ring 220 meshes with the first end-face gear ring 219. One end of the connecting block 222 away from the moving column 221 is fixed to the second end-face gear ring 220. A first towing rope 224 is fixed to the top of the moving column 221. The first towing rope 224 passes through the U-shaped plate 205 and slides inside the U-shaped plate 205. A second elastic member 225 is sleeved outside the first towing rope 224, and one end of the second elastic member 225 abuts against the U-shaped plate 205, and the other end of the second elastic member 225 abuts against the moving column 221.

[0044] When in use, when tree branches and trunks block the weeding path and the operator needs to walk sideways, the first towing rope 224 is pulled to drive the moving column 221 to move upward. When the moving column 221 moves upward, it drives the connecting block 222 to move upward. When the connecting block 222 moves upward, it drives the second end-face gear ring 220 to move upward. When the second end-face gear ring 220 is separated from the first end-face gear ring 219, the control rod 206 can be rotated left and right to drive the U-shaped plate 205 to rotate. When the U-shaped plate 205 rotates, it drives the connecting cylinder 204 to rotate, that is, the angle of the control rod 206 can be adjusted as needed, so that the operator can hold the control rod 206 sideways and the device can still move forward. It should be noted that the second elastic member 225 can use devices such as springs, and in the normal state of the second elastic member 225, the second end-face gear ring 220 and the first end-face gear ring 219 are in a meshed state.

[0045] Furthermore, a connecting shaft 226 is fixed between the two side edges of the U-shaped plate 205. Two annular sleeves 227 are rotatably connected to the connecting shaft 226. Two limiting rings 228 are fixed to the connecting shaft 226. One end of each of the two annular sleeves 227 away from each other abuts against the corresponding limiting ring 228. Connecting plates 229 are fixed to both annular sleeves 227. A rectangular plate 230 is jointly fixed to one end of the two connecting plates 229 away from the annular sleeves 227. Both control rods 206 are fixed to the rectangular plate 230.

[0046] In addition, the secondary adjustment component includes a gear 231 fixed to the outer side of the connecting shaft 226. An inner cavity 232 is formed in the rectangular plate 230. A toothed plate 233 is slidably connected in the inner cavity 232, and the toothed plate 233 meshes with the gear 231. A second towing rope 234 is fixed to one side of the toothed plate 233. The second towing rope 234 penetrates through the rectangular plate 230 and slides within the rectangular plate 230. A third elastic member 235 is sleeved outside the second towing rope 234. One end of the third elastic member 235 abuts against the toothed plate 233, and the other end of the third elastic member 235 abuts against the inner wall of the inner cavity 232. A plurality of first guiding blocks 236 are fixed to one side of the rectangular plate 230 and on one of the control rods 206. The second towing rope 234 penetrates through the first guiding blocks 236 and slides within the first guiding blocks 236. A plurality of second guiding blocks 237 are fixed to the bottom, side and the other control rod 206 of the rectangular plate 230. The first towing rope 224 penetrates through the second guiding blocks 237 and slides within the second guiding blocks 237. Handles 239 are fixed to one ends of the first towing rope 224 and the second towing rope 234. A grip 238 is fixed to the end of the control rod 206 away from the rectangular plate 230.

[0047] During use, when tree branches block the weeding path and the operator needs to bend down to walk, the second towing rope 234 is pulled to drive the toothed plate 233 to move. When the toothed plate 233 is moved into the inner cavity 232, the toothed plate 233 is separated from the gear 231. At this time, the control rod 206 can be rotated downward, so that the rectangular plate 230 drives the connecting plate 229 to rotate. At this time, the annular sleeve 227 rotates on the outer side of the connecting shaft 226, thereby lowering the height of the control rod 206, facilitating the operator to bend down and pass under the tree trunk. In addition, the height of the control rod 206 can be adjusted to meet the needs of operators of different heights. It should be noted that the third elastic member 235 can use devices such as springs, and in the normal state of the third elastic member 235, the toothed plate 233 and the gear 231 are in a meshed state.
