Autonomous cutting mechanism and robot

Abstract

The invention relates to the technical field of mowing devices, in particular to an autonomous cutting mechanism and a robot. The autonomous cutting mechanism applied to plant cutting devices comprises a first blade, a second blade and a first driving assembly, and the first blade is provided with multiple first blade teeth side by side; the second blade overlaps with the first blade and is provided with multiple second blade teeth side by side, the second blade teeth is interlaced with the corresponding first blade teeth, and strip cutting space for accommodating cut objects is formed betweenthe first blade teeth and the second blade teeth; the first driving assembly is connected with the first blade to drive the same to move to the cutting space relative to the second blade to cut the cut objects located in the cutting space. The autonomous cutting mechanism has the advantages of simple structure, uniform force and high degree of automation.

Description

technical field [0001] The invention relates to the technical field of mowing devices, in particular to an autonomous cutting mechanism and a robot. Background technique [0002] The cleaning of aquatic plants is a relatively important and complicated work in river protection. The traditional method of cleaning aquatic plants is manual salvage, which not only cannot guarantee the cleaning effect, but also consumes a lot of physical strength of the nursing staff. The aquatic weed cleaning machine not only has a relatively complicated structure, but also aquatic weeds are easy to block the machine, resulting in extremely inconvenient use. It is an economical and effective method to cut aquatic plants autonomously by small robots, then float them up and bring them downstream for unified processing through water flow. In addition, with the continuous improvement of living standards, people have higher and higher requirements on the living environment, and the grass is usually t...

Problems solved by technology

[0003] The cutter head of lawn mower in the prior art usually selects the gear-shaped cutter head. When this cutter head is in use, due to the relatively large resistance on the cutting surface, the fuselage is prone to instability during cutting. Therefore, the fuselage usually It will be heavier, and the gear-shaped cutter head is not suitable for light-weight lawnmowers; there is also a kind of cutter head, such as Chinese patent document CN107509455A, which discloses a combined type waterweed cutting and collecting system, which adopts a triangular mowing fixed The knife and the triangular mowing knife move relatively to cut the aquatic plants between the mowing fixed knife blade and the mowing moving knife blade. The aquatic plants are all concentrated in the triangular cutting space formed by the mowing fixed blade and the mowing movable blade, and the cutting mechanism receives relatively large resistance in its moving direction. The cutting machine is also not suitable for light-weight lawn mowers

Another type of rotary cutting blade, the rotary cutting blade has high resistance underwater, low efficiency, and it is easy to cause the water weeds of the drive motor to be entangled

[0004] On the other hand, the obstacle detection sensors (such as infrared, ultrasonic, etc.) of existing plant cutting machines are often difficult to distinguish between plants and hard obstacles (such as stones, etc.), making it difficult for robots to achieve autonomous cutting of plants
