Technical Field
[0001] This invention relates to the field of weeding device technology, specifically to an obstacle-avoidance orchard weeding device. Background Technology
[0002] When weeding in an orchard, it is necessary to consider the growth cycle and growth pattern of both fruit trees and weeds, and to choose different treatment methods at different times to clear weeds in order to avoid weeds competing for water and fertilizer and to prevent the breeding of pests and diseases. At the same time, it is necessary to avoid damaging the soil environment and the root system of fruit trees during the clearing process.
[0003] For example, Chinese patent CN222852609U discloses an obstacle-avoiding soil loosening and weeding mechanism and an orchard weeding device. The weeding device has obstacle-avoiding soil loosening and weeding mechanisms symmetrically arranged on both sides. During cleaning, the soil loosening and weeding mechanisms are driven to swing to avoid obstacles.
[0004] However, current weeding equipment needs to be moved by a traveling trolley. When the traveling trolley moves, it inevitably compacts the soil. Moreover, the larger the weeding equipment, the larger the vehicle it needs to be loaded with. During weeding, the soil is compacted and hardened.

[0017] Compared with the prior art, the beneficial effects of this invention are as follows: During the movement, the avoidance lever and the avoidance trigger component are in contact. When encountering a fruit tree, the fruit tree causes the avoidance lever to rotate, disengaging it from the avoidance trigger component. At this time, the avoidance trigger component triggers the rotation component, which drives the rotating mounting frame to rotate 120 degrees. This causes a set of weeding components aligned with the fruit tree and moving between the fruit tree rows to rotate towards the fruit tree rows, moving to the position behind the wheels of the traveling vehicle. The weeding component located on the side of the fruit tree closest to the traveling vehicle rotates to the front of the fruit tree, aligned with the position of the fruit tree moving between the fruit tree rows. The weeding component located on the side behind the wheels of the traveling vehicle rotates to the side of the fruit tree closest to the traveling vehicle. This achieves automatic avoidance, allowing continuous weeding. After automatic continuous adjustment, the soil compacted by the wheels is always tilled by a set of weeding components aligned with the rear of the wheels of the traveling vehicle, thus achieving continuous automatic obstacle avoidance and weeding while preventing the soil from hardening due to wheel compaction.

[0022] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.
[0023] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-3 An obstacle-avoidance orchard weeding device includes a traveling vehicle 1, a moving mechanism 2, an obstacle avoidance mechanism 3, a rotary tillage weeding mechanism 4, and an inter-row weeding mechanism 5. The front side of the traveling vehicle 1 is equipped with an inter-row weeding mechanism 5 for weeding, and the rear side of the traveling vehicle 1 is symmetrically equipped with a moving mechanism 2. like Figure 3 As shown, the moving mechanism 2 includes a positioning component 21 and a lifting component 22. The positioning component 21 is mounted on the traveling vehicle 1, and the lifting component 22 is mounted on the moving end of the positioning component 21. An obstacle avoidance mechanism 3 is mounted on the moving end of the lifting component 22. like Figure 3 As shown, the avoidance mechanism 3 includes a rotating component 31, a rotating mounting frame 32, an avoidance triggering component 33, and avoidance rotating rods 34. The rotating component 31 is mounted on the moving end of the lifting component 22. The rotating mounting frame 32 is mounted on the moving end of the rotating component 31. The three avoidance rotating rods 34 are evenly distributed in a circular array on the rotating mounting frame 32. One end of the avoidance rotating rod 34 is hinged to the rotating mounting frame 32. The avoidance rotating rod 34 and the rotating mounting frame 32 are equipped with a fitting structure for bringing the avoidance rotating rod 34 closer to the avoidance triggering component 33. Three sets of avoidance triggering components 33 are evenly distributed in a circular array on the rotating mounting frame 32. Three sets of rotary tillage and weeding mechanisms 4 for weeding are evenly and uniformly installed on the rotating mounting frame 32; when the traveling vehicle 1 moves along the rows of fruit trees, one set of rotary tillage and weeding mechanisms 4 is located behind the wheels of the traveling vehicle 1.
[0024] like Figure 2 As shown, the rotary tillage and weeding mechanism 4 includes a weeding rotary disk 41, a weeding component 42, a drive component 43, and a drive component 44. The weeding rotary disk 41 is rotatably mounted on a rotary mounting frame 32. The drive component 44 for driving the weeding rotary disk 41 to rotate is mounted on the rotary mounting frame 32. Multiple sets of weeding components 42 are evenly and uniformly arranged in a circular array on the lower side of the weeding rotary disk 41. The drive component 43 for driving the multiple sets of weeding components 42 is mounted on the weeding rotary disk 41.
[0025] like Figure 2 and Figure 3 As shown, the inter-row weeding mechanism 5 includes a second lifting component 51, a weeding support frame 52, a second weeding component 53, and a third driving component 54. The second lifting component 51 is installed on the front side of the traveling vehicle 1. The weeding support frame 52 is installed on the moving end of the second lifting component 51. The second weeding component 53 for weeding is installed on the weeding support frame 52. The third driving component 54 for driving the second weeding component 53 is installed on the second lifting component 51.
[0026] The fitting structure includes a torsion spring. A torsion spring is sleeved on the hinge shaft of the avoidance rotating rod 34 and the rotating mounting bracket 32. The two elastic legs of the torsion spring abut against the avoidance rotating rod 34 and the rotating mounting bracket 32 respectively.
[0027] In this embodiment, when the obstacle-avoiding orchard weeding device is working normally, in the non-operational state, the positioning component 21 is retracted, and the lifting components 1 and 21 are raised, thus facilitating the movement of the traveling vehicle 1. During mowing operations, the traveling vehicle 1 moves between the rows of fruit trees. The lifting component 2 51 drives the weeding support frame 52 to move downwards, causing the weeding component 2 53 on the weeding support frame 52 to move to the working position. The driving component 3 54 drives the weeding component 2 53 to clear the weeds between the fruit tree rows. Simultaneously, the positioning component 21 drives the lifting component 1 22 to unfold, and the rotating component 31 drives the rotating mounting frame 32 to rotate, thereby... Align one set of weeding components 42 on the rotating mounting frame 32 with the rear side of the wheels of the traveling vehicle 1. One set of weeding components 42 is positioned on the side of the fruit tree closest to the traveling vehicle 1, while another set of weeding components 42 moves between the fruit trees. The lifting component 22 drives the rotating component 31, the rotating mounting frame 32, the avoidance trigger component 33, and the avoidance lever 34 to move vertically downward, thereby driving the three sets of weeding rotating discs 41, weeding components 42, drive components 43, and drive components 44 on the rotating mounting frame 32 to move vertically, so that weeding components 42 move to the working position. Drive components 44 drive the weeding rotating discs. 41 rotates, simultaneously driving component 43 to drive weeding component 42. The rotating weeding disc 41, with multiple weeding components 42 on it, performs shallow rotary tillage of the soil, cutting and uncovering the roots of weeds. During travel, the avoidance lever 34 engages with the avoidance trigger component 33. When encountering a fruit tree, the tree causes the avoidance lever 34 to rotate, disengaging it from the avoidance trigger component 33. At this point, the avoidance trigger component 33 triggers the rotating component 31, which in turn rotates the rotating mounting frame 32 120 degrees. This causes a set of weeding components 42, aligned with the fruit tree and moving between its rows, to rotate towards the fruit tree rows. The weeding component 42, located on the side of the fruit tree closest to the vehicle 1, rotates to the front of the fruit tree and moves to the position between the fruit trees. The weeding component 42, located on the side of the vehicle 1 closest to the vehicle 1, rotates to the side of the fruit tree closest to the vehicle 1. This achieves automatic obstacle avoidance, allowing weeding to proceed continuously. After automatic and continuous adjustment, the soil compacted by the wheels is always tilled by a set of weeding components 42 positioned on the rear of the vehicle 1's wheels, thereby achieving continuous automatic obstacle avoidance and weeding while preventing the soil from hardening due to wheel compaction.
[0028] Example 2: In some embodiments, as a preferred embodiment of the present invention, such as... Figures 4-6 and Figure 8As shown, the positioning assembly 21 includes a positioning drive motor 211, a positioning drive gear 212, a positioning driven gear 213, and a positioning rotating frame 214. The positioning drive motor 211 is fixedly installed inside the traveling vehicle 1. The positioning drive gear 212 is fixedly installed at the output end of the positioning drive motor 211. The positioning rotating frame 214 is rotatably installed on the rear side of the traveling vehicle 1. The positioning driven gear 213 is fixedly installed on the positioning rotating frame 214. The positioning drive gear 212 and the positioning driven gear 213 are meshed together. The lifting assembly 22 includes a lifting mounting frame 221, slide rails 223, a lifting hydraulic cylinder 224, a fixed support frame 225, and a floating support module 226. The lifting mounting frame 221 is fixedly mounted on the swing rotating frame 214, and multiple sets of guide grooves 222 are symmetrically opened on the lifting mounting frame 221. Multiple sets of slide rails 223 are symmetrically fixedly mounted on the fixed support frame 225, and the guide grooves 222 are slidably connected to the slide rails 223. The lifting hydraulic cylinder 224 is fixedly mounted on the lifting mounting frame 221, and the output end of the lifting hydraulic cylinder 224 is fixedly connected to the fixed support frame 225. The floating support module 226 is mounted on the fixed support frame 225. The floating support module 226 includes a spring 2261, a limiting block 2262, a guide rod 2263, a floating mounting plate 2264, and casters 2265. Multiple guide rods 2263 are uniformly and evenly fixedly installed in a circular array on the floating mounting plate 2264. The guide rods 2263 are slidably connected to the fixed support frame 225. The limiting block 2262 is fixedly installed on the top of each guide rod 2263. A spring 2261 is sleeved on each guide rod 2263. One end of the spring 2261 is fixedly connected to the limiting block 2262, and the other end is fixedly connected to the fixed support frame 225. Casters 2265 are uniformly and evenly fixedly installed in a circular array at the bottom of the fixed support frame 225.
[0029] like Figures 5-8 As shown, the rotating assembly 31 includes a clearance drive motor 311 and a clearance rotating platform 312. The clearance drive motor 311 is fixedly mounted on the floating mounting plate 2264, and the fixed support frame 225 has a circular groove for making way for the clearance drive motor 311. The output end of the clearance drive motor 311 is fixedly mounted on the clearance rotating platform 312, and the rotating mounting frame 32 is fixedly mounted on the clearance rotating platform 312. The avoidance trigger assembly 33 includes a trigger block 331, a mounting base 332, a round rod 333, a second spring 334, a movable connecting block 335, and a fixed connecting block 336. The trigger block 331 is fixedly mounted on the avoidance rotating rod 34. The mounting base 332 is fixedly mounted on the rotating mounting bracket 32. The round rod 333 is slidably connected to the mounting base 332. The movable connecting block 335 is fixedly mounted in the middle of the round rod 333. The second spring 334 is sleeved on the round rod 333. One end of the second spring 334 is fixedly connected to the mounting base 332, and the other end of the second spring 334 is fixedly connected to the movable connecting block 335. The fixed connecting block 336 is fixedly mounted on the mounting base 332. The end of the round rod 333 passes through the mounting base 332 and abuts against the trigger block 331. The control circuit of the avoidance drive motor 311 is disconnected. One end of the disconnected control circuit of the avoidance drive motor 311 is electrically connected to the movable connecting block 335, and the other end of the disconnected control circuit of the avoidance drive motor 311 is electrically connected to the fixed connecting block 336. When the movable connecting block 335 and the fixed connecting block 336 are in contact, the control circuit of the avoidance drive motor 311 is closed.
[0030] In this embodiment, the positioning drive motor 211 drives the positioning drive gear 212 to rotate, and the positioning drive gear 212 drives the positioning rotating frame 214 to rotate through the positioning driven gear 213, thereby driving the lifting mounting frame 221 to rotate. This allows the lifting mounting frame 221 and its related structures mounted on it to retract to the rear of the traveling vehicle 1 in the non-operating state, facilitating movement between rows in the orchard. During operation, the positioning drive gear 212 drives the positioning rotating frame 214 and the lifting mounting frame 221 to unfold through the positioning driven gear 213. The lifting hydraulic cylinder 224 drives the fixed support frame 225 in the guide groove 2. Under the limiting action of 22 and slide rail 223, it moves vertically, thereby moving the weeding component 42 away from the ground in the non-operating state, and moving it downward to weed in the operating state; after moving downward, the caster wheel 2265 contacts the ground, and the floating mounting plate 2264 and guide rod 2263 move vertically relative to the fixed support frame 225, causing the spring 2261 to be compressed; thus, during operation, through the floating support of the caster wheel 2265, spring 2261, and guide rod 2263, it is easy to adjust itself when moving on uneven road surfaces, so that the rotary tillage depth of the weeding component 42 remains stable; When moving horizontally, the avoidance lever 34 is perpendicular to the direction of travel. The trigger block 331 on the avoidance lever 34 presses against the round rod 333, causing the round rod 333 to move on the mounting base 332. At this time, the moving connecting block 335 moves away from the fixed connecting block 336, the control circuit of the avoidance drive motor 311 is disconnected, and the second spring 334 is compressed. When the avoidance lever 34 is blocked by a fruit tree, the avoidance lever 34 is pushed, causing the trigger block 331 to move away from the round rod 333. The torque between the avoidance lever 34 and the rotating mounting bracket 32 is reduced. The spring twists; the spring 334 returns to its original position, causing the round rod 333 to move, so that the moving connecting block 335 on the round rod 333 is pressed against the fixed connecting block 336. The control circuit of the obstacle avoidance drive motor 311 is closed, triggering the obstacle avoidance drive motor 311 to start and drive the obstacle avoidance rotating table 312 to rotate, thereby driving the rotating mounting frame 32 to rotate; the rotating mounting frame 32 drives the weeding rotating disk 41 to rotate, completing the obstacle avoidance. At this time, the torsion spring between the obstacle avoidance rod 34 and the rotating mounting frame 32 returns to its original position, causing the obstacle avoidance rod 34 to return to its original position.
