Description
Technical field
The invention belongs to agricultural mechanical field, relate to a kind of farmland weeding machine, especially relate to a kind of farmland weeding machine based on machine vision weed identification.
Background technology
Farmland weed is an ingredient in Agro-ecological System, it directly or indirectly affects agricultural production, weeds and crops contention nutrient, moisture, illumination and space, infectious disease insect pest, affect crop growthing development, in turn result in crop failure, quality reduction. The mode of current weeding has chemical weeding, artificial weeding, mechanical means weeding etc. Chemical weeding is current most widely used a kind of weeding system, has quick, efficient, economic dispatch feature, but a large amount of use of herbicide brings the problems such as ecological environmental pollution, herbicide resistance enhancing, bio-diversity minimizing. Artificial weeding inefficiency, labor intensity are big. And mechanical means weeding work efficiency is high, environmental pollution is little, meet the development need of green agriculture. Therefore, the machine being applicable to cut weeds in farmland is developed significant for improving agricultural production efficiency.
Summary of the invention
For the shortcomings and deficiencies existed in above-mentioned prior art, the invention provides a kind of farmland weeding machine carrying out weeding operation under farm environment, this weeder location rational in infrastructure, quick, weeding are accurate.
For achieving the above object, the present invention is by the following technical solutions:
A kind of farmland weeding machine based on machine vision weed identification specifically includes that guide wheel (1), controller (2), pedestal (3), support (4), turnbarrel (5), No. 1 photographic head (6), No. 2 photographic head (7), No. 3 photographic head (8), transversal stretching bar (9), longitudinal extension bar (10), tool bit cover (11), mowing cutter heads (12); It is characterized in that, described support (4) and controller (2), guide wheel (1) are arranged on pedestal (3), top and No. 1 photographic head (6), No. 2 photographic head (7), No. 3 photographic head (8) of its medium-height trestle (4) are fixedly connected with, three photographic head are respectively distributed to the left of farmland weeding machine, front and right, and support (4) is connected with turnbarrel (5) formation revolute pair; Transversal stretching bar (9) and longitudinal extension bar (10) are fixedly connected with, and wherein longitudinal extension bar (10) and tool bit cover (11) are fixedly connected with; Mowing cutter head (12) is arranged on the end of longitudinal extension bar (10).
The operation principle of a kind of farmland weeding machine based on machine vision weed identification of the present invention: when farmland weeding machine is when field work, three photographic head can to a left side, right, the image collected on first three direction carries out weed identification, weeds are recognized once certain photographic head, controller (2) calculates the actual coordinate of weeds in corresponding photographic head by image recognition algorithm, and by weeds Coordinate Conversion polar coordinates form, controller (2) controls turnbarrel and rotates corresponding angle, regulate transversal stretching bar (9), the length of longitudinal extension bar (10), mowing cutter head (12) is made to be positioned weeds place, controller (2) controls mowing cutter head (12) and has rotated weeding work,After weeding terminates, mowing cutter head (12) stops the rotation, longitudinal contraction bar (10) shrinks mowing cutter head (12) lift-off ground, cross-direction shrinkage bar (9) shrinks, cross-direction shrinkage bar (9) is rotated to the rear of farmland weeding machine by turnbarrel (5), in case cross-direction shrinkage bar (9) or longitudinal contraction bar (10) hinder the visual field of photographic head, affect weed identification.
The invention have the benefit that
1, present configuration is reasonable, is movably walking flexibly, identifies that weeds are accurate.
2, the present invention carries out operation under farm environment, and weeding ratio is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of farmland weeding machine based on machine vision weed identification of the present invention.
Fig. 2 is the top view of a kind of farmland weeding machine based on machine vision weed identification of the present invention.

In figure: 1, guide wheel; 2, controller; 3, pedestal; 4 supports; 5, turnbarrel; 6, No. 1 photographic head; 7, No. 2 photographic head; 8, No. 3 photographic head; 9, transversal stretching bar; 10, longitudinal extension bar; 11, tool bit cover; 12, mowing cutter head
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is further explained explanation:
Fig. 1 illustrates that embodiments of the present invention, a kind of farmland weeding machine based on machine vision weed identification specifically include that guide wheel (1), control box (2), pedestal (3), support (4), turnbarrel (5), No. 1 photographic head (6), No. 2 photographic head (7), No. 3 photographic head (8), transversal stretching bar (9), longitudinal extension bar (10), mowing cutter heads (12); It is characterized in that, described support (4) and control box (2), guide wheel (1) are arranged on pedestal (3), top and No. 1 photographic head (6), No. 2 photographic head (7), No. 3 photographic head (8) of its medium-height trestle (4) are fixedly connected with, three photographic head are respectively distributed to the left of farmland weeding machine, front and right, and support (4) is connected with turnbarrel (5) formation revolute pair; Transversal stretching bar (9) and longitudinal extension bar (10) are fixedly connected with, and wherein longitudinal extension bar (10) and tool bit cover (11) are fixedly connected with; Mowing cutter head (12) is arranged on the end of longitudinal extension bar (10). When weeder is when farm work, No. 1 photographic head (6), No. 2 photographic head (7), No. 3 photographic head (8) gather image information from left, three directions of front right respectively, when certain photographic head detects weeds, it is calculated obtaining the actual coordinate of weeds by controller (2), by converting rectangular coordinate to polar coordinate, weeds is positioned.
Described transversal stretching bar (9) is connected with longitudinal extension bar (10), and wherein transversal stretching bar (9) and turnbarrel (5) are fixedly connected with; Longitudinal extension bar (10) and tool bit cover (11) are fixedly connected with, and cutter head of mowing (12) is connected to the end of longitudinal extension bar (10). After weeds being positioned by controller (2), turnbarrel (5) rotates corresponding angle, mowing cutter head (12) is moved to weeds place by the height regulating transversal stretching bar (9) length and longitudinal extension bar (10), then controller (2) control mowing cutter head (12) rotates so that it is weeds are purged. After weeding terminates, mowing cutter head (12) stops the rotation, longitudinal contraction bar (10) shrinks mowing cutter head (12) lift-off ground, cross-direction shrinkage bar (9) shrinks, cross-direction shrinkage bar (9) is rotated to the rear of farmland weeding machine by turnbarrel (5), in case cross-direction shrinkage bar (9) or longitudinal contraction bar (10) hinder the visual field of photographic head, affect weed identification.
The structure and working principle of the present invention it is explained above with specific embodiment; the invention is not limited in above example; according to above-mentioned description; all any amendment, replacement and improvement etc. made within the spirit and principles in the present invention, should be included within protection scope of the present invention.
