The utility model provides a solar panel is fixed gets the energy efficiency limited and greenhouse electric tractor continuity of operation is limited, the short scheduling problem of the distance of traveling, improved the efficiency of agricultural machine operation.
Description
Technical field
The utility model belongs to agricultural mechanical field, is specifically related to the miniature crawler tractor of a kind of solar energy greenhouse.
Background technology
At present, the problems such as in China's warmhouse booth, the power machine of operation is mainly traditional internal combustion engine tractor, there is energy transformation ratio low during its work, seriously polluted.Along with the lifting of oil price, in warmhouse booth, the cost of operation also increases gradually.Sun power belongs to clean energy resource, environmental protection, inexhaustible.To the direct utilization of sun power, start the new height of human development, be conducive to social sustainable development.Therefore, developing a kind of take sun power as the miniature crawler tractor of power is very useful.Although China has disclosed some greenhouse miniature electric tractor and solar automobiles, but ubiquity uninterrupted working time is limited, traveling distance is short, solar panel is fixed, get the problems such as energy efficiency is limited, fail the performance of the larger miniature crawler tractor in performance greenhouse.
Utility model content
The purpose of this utility model is to provide a kind of solar energy greenhouse miniature crawler tractor, when sunny, directly provides electrical energy drive crawler tractor to advance and for charge in batteries with solar panel; When sunlight is not enough, electrical energy drive crawler tractor is jointly provided to advance with accumulator and solar panel; When there is no sunlight, only provide electrical energy drive crawler tractor to advance with accumulator, and when continuous rainy weather, be equipped with emergent charging power supply.And described solar panel can adjust its orientation automatically according to the power of illumination, thus improve the work efficiency of cell panel.
In order to realize described object, the utility model adopts following technical scheme to be achieved:
The miniature crawler tractor of described solar energy greenhouse comprises the solar panel automatic light tracking system at miniature crawler tractor and top thereof, and described solar panel automatic light tracking system mainly comprises: controller, solar panel, sensor, stepper motor, Twin-shaft machinery support.

Embodiment
With reference to Fig. 2, the solar panel automatic light tracking system at the miniature crawler tractor top of described solar energy greenhouse mainly comprises: STC89C54, solar panel, PSD sensor, stepper motor, stepper motor driver, Twin-shaft machinery support.
When solar irradiation is mapped on solar panel, PSD can detect the electric current that solar panel produces, electric current is sent to STC89C54 single-chip microcomputer and carry out analog to digital conversion, the position of the sun is judged by single-chip microcomputer, then controlled quentity controlled variable is sent to control the rotation of Twin-shaft machinery support with Driving Stepping Motor to stepper motor driver, to adjust deflection and the angle of pitch of solar panel, thus make solar panel vertical with sunray, make solar panel receive sun power to greatest extent.
With reference to Fig. 3, the mechanical part of described light tracing system comprises: solar panel, T-shaped support, cam, connecting rod, turbine and worm decelerator and 2 drive motor compositions, with PSD detector on described solar panel.
Described solar panel automatic light tracking system adopts double-axis tracking method, and namely solar panel is by around the independently action and change deflection and the angle of pitch of system of vertical axes and transverse axis.After single-chip microcomputer spreads out of control signal, stepper motor A drives T-shaped support to realize horizontal direction through worm type of reduction gearing and rotates, i.e. azimuthal adjustment.And stepper motor B drives cam mechanism to be realized the adjustment of the angle of pitch by universal coupling.By the control to stepper motor, just can reach the control to follower travel direction angle and the angle of pitch, thus make solar panel vertical with sunray.
With reference to Fig. 4,5,6, charging circuit comprises: diode, solar panel, the accumulator of exportable 12V.
When sunny, when the voltage that solar panel is produced is more than 12V, Fig. 4 circuit turn-on, now solar panels are directly for car provides required electric energy, and meanwhile, solar panel is charge in batteries.
When sunlight is not enough, when the voltage that solar panel is produced is lower than 12V, the diode cathode voltage of connecting with solar panel in Fig. 5 is higher than positive pole, solar panel is transmission of electric energy no longer, therefore accumulator is only had to provide electric energy, in the circuit of the right, solar panel provides circuit, realizes providing electric energy simultaneously.
When not having sunlight, the circuit in Fig. 6 directly provides required electric energy by accumulator, and is connected with emergent charging power supply, in case the overcast and rainy equipment that causes can not work in time continuously.
