Description

Technical Field

[0001] This utility model relates to the field of weeding device technology, and more specifically, to a height adjustment mechanism for a weed identification camera. Background Technology

[0002] Rubber grass, as an important rubber-producing crop, has potential value in industrial applications. However, its cultivation typically relies on manual observation and weeding, which is unsuitable for large-scale planting. Therefore, it is necessary to use weeding robots to identify and remove weeds from rubber grass.

[0003] In actual use, the identification camera installed on the outside of the weeding robot is used to identify weeds in the rubber grass. During this process, when identifying weeds on uneven soil, due to the growth characteristics of rubber grass, especially rubber grass growing in water-scarce and saline-alkali lands such as Xinjiang, which is not tall and the ground is mostly sandy or compacted, the identification camera is prone to collision and shaking with the soil, which affects the accuracy of the identification camera in identifying weeds. Utility Model Content

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a camera height adjustment mechanism for rubber grass planting identification, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A height adjustment mechanism for a rubber grass planting identification camera includes two positioning frames. A base frame is slidably connected to the inner side of each positioning frame. A visual recognition camera body is fixedly connected to the top of the base frame. A guide lifting mechanism is provided on the outer side of the base frame. The guide lifting mechanism includes multiple positioning cylinders. The outer side of each positioning cylinder is fixedly connected to one side of the base frame. A bottom rod is fixedly connected to the top of each positioning cylinder. A top rod is slidably connected to the outer side of the bottom rod. Springs are sleeved on the outer sides of the bottom rod and the top rod. The bottom end of the spring is fixedly connected to the outer side of the bottom rod, and the top end of the spring is fixedly connected to the bottom of the top rod. Positioning posts are inserted into the inner side of each positioning cylinder. Two bases are fixedly connected to the bottom ends of the multiple positioning posts. Bolts are provided on the inner sides of the two positioning posts. The outer sides of the bolts penetrate the inner sides of the positioning cylinders and positioning posts. The top end of the top rod is fixedly connected to the lower surface of the positioning frame. A mounting frame is rotatably connected to the bottom of the base. Two shock absorbers are hinged to the upper surface of the mounting frame. One end of each shock absorber is hinged to the lower surface of the base. Two rotating rollers are rotatably connected to the inner side of the mounting frame. Two rubber wheels are fixedly connected to the outer sides of the rotating rollers. A lifting mechanism is provided on the outer side of the positioning frame.

[0007] By adopting the above technical solution: using two shock absorbers to push the mounting frame to deflect at the bottom of the base, the mounting frame, two rotating rollers, and rubber wheels are tilted and rolled in contact with the ground. Combined with the compression and contraction of multiple springs, the base rod, positioning cylinder, base frame, and visual recognition camera body are lifted and lowered, avoiding collisions between the base frame and visual recognition camera body and the ground. The positioning cylinder can be separated from the positioning column by bolts, making it easy to remove and replace multiple rotating rollers and rubber wheels.

[0008] As a further description of the above technical solution: the lifting mechanism includes multiple guide rods, the bottom end of the guide rods is fixedly connected to the top of the positioning frame, two guide rods are symmetrically arranged on the upper surface of the positioning frame, an mounting plate is slidably connected to the outer side of the guide rods, two electric cylinders are fixedly connected to the inner side of the mounting plate, a fixing frame is fixedly connected to the bottom end of the electric cylinders, and one side of the fixing frame is fixedly connected to the outer side of the positioning frame.

[0009] By adopting the above technical solution: using multiple guide rods to guide at multiple points along with the mounting plate, and using two electric cylinders to push two positioning frames to drive the base frame and the main body of the visual recognition camera to rise and fall, the main body of the visual recognition camera can maintain a suitable recognition height with the weeds in the rubber grass.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] By setting up a guide lifting mechanism, compared with the existing technology, the elastic deflection supported by the shock absorber and the combination of multiple springs to the positioning cylinder and elastic support can make the base frame and the visual recognition camera body maintain a suitable distance from the protrusions of different heights on the ground, reduce the collision and shaking of the visual recognition camera body when running on uneven soil, and maintain the accuracy of the visual recognition camera body in identifying weeds.

[0012] By setting up a lifting mechanism, compared with the existing technology, multiple guide rods are used to limit and guide the lifting of the positioning frame at multiple points. Combined with the extension and retraction of two electric cylinders, the main body of the visual recognition camera maintains stability during the lifting and lowering process, and the recognition height of the main body of the visual recognition camera is stably adjusted.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] The embodiments disclosed in this application are as follows: Figures 1-6The illustrated height adjustment mechanism for a rubber grass planting identification camera includes two positioning frames 1. A base frame 2 is slidably connected to the inner side of the positioning frame 1. A visual recognition camera body 3 is fixedly connected to the top of the base frame 2. A guide lifting mechanism is provided on the outer side of the base frame 2. The guide lifting mechanism includes multiple positioning cylinders 4. The outer side of the positioning cylinder 4 is fixedly connected to one side of the base frame 2. A bottom rod 5 is fixedly connected to the top of the positioning cylinder 4. A top rod 6 is slidably connected to the outer side of the bottom rod 5. Springs 7 are sleeved on the outer sides of the bottom rod 5 and the top of the top rod 6. The bottom end of the spring 7 is fixedly connected to the outer side of the bottom rod 5, and the top end of the spring 7 is fixedly connected to the bottom of the top rod 6. Positioning posts 8 are inserted into the inner side of the positioning cylinders 4. Two bases 9 are fixedly connected to the bottom ends of the multiple positioning posts 8. Bolts 10 are provided on the inner side of the two positioning posts 8. The outer side of the bolts 10 penetrates the inner side of the positioning cylinders 4 and the positioning posts 8. The top end of the top rod 6 is fixedly connected to the lower surface of the positioning frame 1. The base 9 is rotatably connected to a mounting frame 11. Two shock absorbers 12 are hinged to the upper surface of the mounting frame 11. One end of the shock absorber 12 is hinged to the lower surface of the base 9. Two rotating rollers 13 are rotatably connected to the inner side of the mounting frame 11. Two rubber wheels 14 are fixedly connected to the outer side of the rotating rollers 13. A lifting mechanism is set on the outer side of the positioning frame 1. The two shock absorbers 12 buffer the mounting frame 11, the two rotating rollers 13, and the rubber wheels 14 so that they can tilt and roll to fit the ground protrusion. At the same time, the mounting frame 11 pushes the base 9, the positioning column 8, the positioning cylinder 4, and the bottom rod 5 to squeeze and push the spring 7, so that the multiple bottom rods 5 can slide and guide inside the top rod 6. The two sets of mounting frames 11 drive the positioning cylinder 4, the base frame 2, and the visual recognition camera body 3 to rise and fall with the ground protrusion, avoiding the collision between the base frame 2 and the visual recognition camera body 3 and the ground protrusion.

[0022] Reference Figure 1 , Figure 3 and Figure 6 As shown, the lifting mechanism includes multiple guide rods 15. The bottom end of the guide rod 15 is fixedly connected to the top of the positioning frame 1. Two sets of guide rods 15 are symmetrically arranged on the upper surface of the positioning frame 1. A mounting plate 16 is slidably connected to the outside of the guide rod 15. Two electric cylinders 18 are fixedly connected to the inside of the mounting plate 16. A fixing frame 17 is fixedly connected to the bottom of the electric cylinder 18. One side of the fixing frame 17 is fixedly connected to the outside of the positioning frame 1. The two electric cylinders 18 push the fixing frame 17 to drive the positioning frame 1 to lift and lower. In conjunction with the multiple guide rods 15, the positioning frame 1 provides multi-point guidance inside the mounting plate 16, so that the two positioning frames 1 can drive the base frame 2 and the visual recognition camera body 3 to lift and lower smoothly.

[0023] The working principle of this utility model is as follows: When identifying weeds during rubber grass planting, the mounting plate 16 is first screwed to the outside of the weeding robot. During the operation of the weeding robot, two electric cylinders 18 are activated to push the fixed frame 17 and the positioning frame 1 to rise and fall at the bottom of the mounting plate 16. Multiple guide rods 15 slide up and down on the inner side of the mounting plate 16, allowing the two positioning frames 1 to drive the base frame 2 and the visual recognition camera body 3 to rise and fall, so that the visual recognition camera body 3 can maintain a suitable height for weed identification. Then, when the weeding robot moves on uneven ground, when the base frame 2 contacts and collides with the raised ground, the two electric cylinders 18 push the fixed frame 17 and the positioning frame 1 to rise and fall at the bottom of the mounting plate 16. The hinged mounting bracket 11 at the bottom of the base 9, together with the two shock absorbers 12 on the lower surface of the base 9, provides elastic support to the upper surface of the mounting bracket 11. This allows the two rotating rollers 13 and the corresponding rubber wheels 14 at the bottom of the mounting bracket 11 to roll and rub against the ground. At the same time, when the ground protrudes too much and causes a collision between the visual recognition camera body 3 and the base frame 2, the multiple rotating rollers 13 and rubber wheels 14 can push the positioning column 8 and the positioning cylinder 4 to push and squeeze the multiple bottom rods 5 and the spring 7, causing the multiple bottom rods 5 to slide against the inner side of the top rod 6. This allows the base frame 2 and the visual recognition camera body 3 to rise and fall to a certain extent with the ground protrusion, so that the visual recognition camera body 3 can continuously maintain the recognition of weeds in the rubber grass.
