Embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
As shown in the figure, a kind of lawn picture and text trimmer, comprise frame 2, be provided with below described frame 2 by motor-driven four wheels 7 of advancing, described frame 2 is provided with car body 10, car body 10 is provided with the cutter arrangement 8 for cutting the grass on a lawn, car body 10 is formed by the sliding bar 4 and frame 2 being installed in frame 2 two ends and is slidably connected, frame 2 upper end is also provided with drive link 9, and drive link 9 one end connects motor I 3, other end connection body 10; Four supporting disks 1 are provided with below frame 2, one is all connected with for regulating the lift cylinder 6 of car body 10 height between each supporting disk 1 and frame 2, after driving car body 10 to rise by lift cylinder 6, motor I 3 outputting power, moved back and forth along sliding bar 4 direction by drive link 9 drive chassis 2, lift cylinder 6, to complete the pruning to lawn, is shunk the pruning continuing next line after completing by the movement realizing cutter arrangement 8 position.
Described cutter arrangement 8 comprises toolframe 805, toolframe 805 upper end is provided with motor II 804, motor II 804 output connecting thread bar 803, threaded rod 803 lower end is connected in frame 2, drive threaded rod 803 transmission to regulate the height of cutter arrangement 8 by motor II 804, described toolframe 805 is also vertically provided with two connecting rods 806, and connecting rod 806 lower end connects motor III 802, and motor III 802 output connects cutter 801.
Described cutter 801 adopts two tooth diamond shaped insert, and described blade is rotary cutter.
Described sliding bar 4 is provided with slidably slide block 5, and car body 10 is fixedly connected with slide block 5.
Only need input the data wanting print pattern and word during operation, then lawn picture and text automatic pruning machine is put into initial position, just can start working, and without the need to other operation, convenient and swift, real realizes automation, intelligent.
This device does not adopt common parallelogram connection-rod steering mechanism, and adopts the method for x-axis translation, and the error being intended to lawn picture and text automatic pruning machine is produced in traveling process drops to minimum.Realize the device of lawn picture and text automatic pruning machine x-axis by cylinder, feed rod, the compositions such as motor, concrete moving method is: first risen by dolly with cylinder, then by the transmission of driven by motor feed rod, realizes dolly transverse shifting.Cylinder is after rising dolly together with moving track, and by driven by motor leading screw, leading screw connects dolly, dolly is slided, so just achieve the movement of dolly along x-axis along parallel track.After its translation terminates, then its cylinder is shunk, after dolly is put down, then leading screw is regained, namely start the second row of printing character pattern; Above-mentioned steps is repeated until print complete by whole pattern or word when needs print next line.
The target of lawn picture and text trimmer is generally lower soft weeds, and therefore we have selected 2 tooth diamond shaped insert, and its blade is rotary cutter, and rotary general motion steadily, vibrations are less, mechanism simple, is widely adopted.During work, blade rotates at horizontal plane, revolve blade cutting edge and generally have 15 degree of relief angles, another side forms empennage with definite shape, certain angle, the impeller forming a mixed flow fan can coordinate with inner chamber, axis (vertical direction) can be formed when cutting grass, grass blade picks up uprightly, to reach good pruning effect by radial (horizontal direction) air-flow.
This lawn picture and text automatic pruning machine is by Single-chip Controlling, and first system communicates with host computer, gets the data that user needs to prune.After waiting for single-chip microcomputer electrification reset, program is first to each chip initiation.The pattern pruned is deposited in an array, and it prunes with the principle of liquid crystal display similar.The lawn that first single-chip microcomputer will be pruned is divided into dot matrix region one by one, then independently judging that the position at current place is the need of falling hay knife, cuts, so also just achieving the function of pruning out various different patterns.
Lawn picture and text automatic pruning machine is first connected with PC by user, and the character pattern that will prune is input to MCU controller.Then picture and text automatic pruning machine in lawn is by various kinds of sensors navigation system, realize the precise positioning of lawn picture and text automatic pruning machine, then according to the principle of the display character pattern of LCDs, the region that will prune is divided into lattice module one by one, cutter under specific region, realizes the object that character pattern is pruned.Concrete steps are by communicating with host computer, and by user, the character pattern will pruned on lawn carries out delivery process to host computer, character pattern is split into lattice module one by one.
The main control chip that this problem is taked is the ATmega16 single-chip microcomputer that AVR company produces.The characteristic of its high-performance, low cost, low-power consumption is highly suitable for the control of this lawn picture and text automatic pruning machine.
In order to solve mower walk in traveling process occur walking offset issue, this lawn picture and text automatic pruning machine have employed ZigBee/CC2431 real-time positioning system.The location algorithm that CC2431 uses is based on the received signal strength indicator received (Received SignalStrength Indicator).Increase along with distance reduces by RSSI value.
Lawn picture and text automatic pruning machine not only can realize the pruning of character pattern after determining the orientation of oneself, can also adjust the attitude of self, corrects the deviation produced because of road conditions in traveling process.
