Among the figure: 1 microcontroller, 2 power modules, 3 clock circuits, 4 position transducers, 5 LCD MODULEs, 6 pressure transducers, 7 key-press modules, 8 instrument housings, 9 holders, 10 buttons.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further.
As shown in Figure 1, provided the circuit theory diagrams of the shovel loader motor weighing instrument of the utility model, it comprises microcontroller 1, power module 2, clock circuit 3, position transducer 4, LCD MODULE 5, pressure transducer 6, key-press module 7; Microcontroller 1 plays signals collecting, data operation and signal output, is to realize the intelligentized core devices of weighing instrument.Power module 2 provides electric energy for the normal work of whole weighing instrument, and clock circuit 3 provides the pulse clock of operate as normal to microcontroller.
Position transducer 4 is connected with the input port of microcontroller 1, is used to detect the lifting height of the lifting swing arm of shovel loader; Pressure transducer 6 also is connected with the input end of microcontroller 1, owing to detect the hydraulic fluid pressure that promotes the swing arm fluid power system, so that calculate the weight that shovel loader loads.LCD MODULE 5 is connected with microcontroller 1, be used for the job information of shovel loader is shown so that human pilot can be in time, the job information of read machine easily.Key-press module 7 is connected with microcontroller 1, is used for input operation or query statement.
In the process of work, have only when the lifting swing arm rises to certain altitude, just can make position transducer 4 produce trigger pips; Produced after the trigger pip, just can carry out weight and measure, guaranteed the precision of measuring effectively through pressure transducer 6.
Of Fig. 2, provided the structure principle chart of instrument housing in the utility model, shown LCD MODULE 5 is arranged on the instrument housing 8, and instrument housing 8 is also realized the protective effect to LCD MODULE simultaneously.Also be provided with holder 9 and a plurality of buttons 10 on the instrument housing 8, instrument housing 8 can be fixedly mounted on the corresponding pedestal through holder 9; Human pilot is through button 10, but input inquiry, steering order.
In the process of using; Should note: should start shovel loader earlier before the start of shovel loader electronic scales; Promote swing arm and do the preheating lifting for 5-10 time, its objective is to make hydraulic oil and pressure transducer be preheating to the normal working temperature of using, reduce the influence of oil instability weighing precision.(2) in weighing process, should avoid shovel loader to go, weigh finish after arbitrarily travel speed do not limit.As in weighing, going, then the speed of a motor vehicle should be controlled at below the 5km/h, but the accuracy meeting reduces by 0.5%.(3) in weighing process, when promoting swing arm through position transducer, pulling speed is (stop to add/subtract throttle or throttle pauses) as far as possible evenly.(4) shovel loader should be chosen in than promoting on the ground of level or under the situation of the gradient less than 15 degree as far as possible and weigh.(5) after completion was this time weighed, hopper should fall back to extreme lower position, weighed in order to shoveling material next time.
