Abstract
The present invention discloses a loader electronic scale A which belongs to the weighting and metering device and settles the problems of easy being damaged of the acceleration transducer and cost increasing of the electronic scale when the loader bucket is arranged with an acceleration transducer in the existing technique for modifying the measurement deviation caused by the acceleration in the movement of the bucket, the loader electronic scale comprises a loader large arm (1), a hydraulic push rod (2), a pressure sensor (3) and a secondary instrument (4) arranged in the steering room of the loader; the loader large arm (1) is arranged with a weighting transducer (5) which is electrically connected with the secondary instrument (4), the fixed end of the weighting transducer (5) is permanently connected on the arm body of the loader large arm (1), and the weighting end of the weighting transducer (5) is arranged with a heavy block (6). The electronic scale of the invention has the advantages of simple structure, convenient maintenance, and increasing the metering accuracy of the loader electronic scale.
Description
Technical field
The present invention relates to a kind of Weighing instrument, particularly a kind of electronic weighing system of shovel loader.
Background technology
The shovel loader electronic scales generally all utilizes hydrostatic transmission to measure, this metering method be pack in the in-line of the boom cylinder on loading shovel measure liquid pressure pressure transducer in order to measure the transducing signal of contained quality on the scraper bowl, receive above-mentioned transducing signal and change, demonstrate contained quality by secondary instrument.This measuring method can be because the wearing and tearing of oil temperature, pollution, sealing gasket reach the dynamic factor that carries out Dynamic Weighting in advancing, and cause that measuring accuracy is not high, poor reliability and can't promoting.Number of patent application is that 200410079234.6 application discloses a kind of position of bucket measuring switch group and computer automatic analysis control module that adopts lifting force cell group, forms near switch and the technical scheme that acceleration transducer is set on scraper bowl solves the not technical matters of high reliability difference of shovel loader electronic weighing system precision.But this scheme has following shortcoming: because it is near switch with several, revise the error of metering with the position of the form detection of dynamic scraper bowl of discontinuous point, the correction of error in dipping can not be in all directions each position the during load-carrying of real-time follow-up scraper bowl incessantly, this correction is science not, poor reliability, limited to the deflection difference that measures inclined to one side value, damage easily near switch simultaneously, the position of its installation is on the workplace of load wagon, and the probability of its damage is very big.The measurement deviation that the acceleration of this scheme for to bucket motions the time causes is revised, acceleration transducer has been installed on scraper bowl, but the higher and easy damage of acceleration transducer price, this technical scheme had both increased the cost of electronic scales, be not suitable for site work again, because the working environment of the scraper bowl of shovel loader is very poor, it is unrealistic that acceleration transducer is installed on scraper bowl.
Summary of the invention
The technical matters that the present invention solves is: weight metering deviation that the acceleration of acceleration transducer in order to bucket motions the time cause is installed when revising at prior art on loading shovel, acceleration transducer is damaged and has increased the problem of the cost of electronic scales easily, provide a kind of simple in structure, with low cost, under the loading shovel dynamic environment, can obtain the shovel loader electronic scales of higher weighing accuracy.
The present invention is achieved by the following technical programs:
The shovel loader electronic scales, comprise the big arm 1 of shovel loader, hydraulic push rod 2, pressure transducer 3, at the secondary instrument 4 of the indoor setting of loader drive, the big arm 1 of described shovel loader is provided with a LOAD CELLS 5, this LOAD CELLS 5 is electrically connected with described secondary instrument 4, the stiff end of LOAD CELLS 5 is fixedly connected on the arm body of the big arm 1 of shovel loader, and the end of weighing of LOAD CELLS 5 is provided with pouring weight 6.
Described LOAD CELLS 5 is preferably disposed on the end position of the big arm 1 of shovel loader of big arm 1 of shovel loader and lifting bucket junction.
Described LOAD CELLS (5) can be the cantilevered LOAD CELLS.
The present invention is simple in structure, and is easy to maintenance, reduced the cost cost of shovel loader electronic scales, improved the weight metering precision of shovel loader electronic scales.

Embodiment
The shovel loader electronic scales, comprise the big arm 1 of shovel loader, hydraulic push rod 2, pressure transducer 3, at the secondary instrument 4 of the indoor setting of loader drive, the big arm 1 of described shovel loader is provided with a LOAD CELLS 5, this LOAD CELLS 5 is electrically connected with described secondary instrument 4, the stiff end of LOAD CELLS 5 is fixedly connected on the arm body of the big arm 1 of shovel loader, and the end of weighing of LOAD CELLS 5 is provided with pouring weight 6.During shovel loader work, if body sway, the big arm 1 of shovel loader also tilts with equal angular, be installed in LOAD CELLS 5 on the big arm 1 of shovel loader and scraper bowl also simultaneously with identical angle tilt, at this moment the component vertically downward of 6 weight of the balancing weight on the LOAD CELLS is to change with identical ratio with the component vertically downward of the interior weight of material of scraper bowl, thereby compensates the accurate weight that computing obtains the material in the scraper bowl according to 4 pairs of electric signal that transmitted by LOAD CELLS 5 and pressure transducer 3 of this ratio secondary instrument.Simultaneously, when shovel loader makes progress the lifting scraper bowl with a certain acceleration, because the acting force that this acceleration produces can embody on LOAD CELLS 5, thereby secondary instrument will compensate the accurate weight that computing obtains the material in the scraper bowl according to the electric signal that LOAD CELLS 5 and pressure transducer 3 transmit, and has overcome the influence to measuring accuracy in the scraper bowl that lifting brings because the acceleration of scraper bowl makes progress.
Described LOAD CELLS 5 is preferably disposed on the end position of the big arm 1 of shovel loader of big arm 1 of shovel loader and lifting bucket junction.Described LOAD CELLS 5 can be the cantilevered LOAD CELLS.
Claims (3)
1, a kind of shovel loader electronic scales, comprise the big arm of shovel loader (1), hydraulic push rod (2), pressure transducer (3), at the secondary instrument (4) of the indoor setting of loader drive, it is characterized in that, the big arm of described shovel loader (1) is provided with a LOAD CELLS (5), this LOAD CELLS (5) is electrically connected with described secondary instrument (4), the stiff end of LOAD CELLS (5) is fixedly connected on the arm body of the big arm of shovel loader (1), and the end of weighing of LOAD CELLS (5) is provided with pouring weight (6).
