Description
Technical field
The utility model relates to a kind of intelligent weighing device, especially for the intelligent weighing device of shovel loader.
Background technology
Shovel loader is a kind of instrument that loads railway bulk cargo, just can weigh to goods for being implemented in the loading process, has worked out multiple shovel loader weighing technology.In the prior art, a kind of weighing device that adopts the pressure transducer that hydraulic system installs is arranged, but it is influenced by cleanliness, Hydraulic Elements wearing and tearing, the swing arm hoisting acceleration of temperature, the hydraulic oil of hydraulic oil, the gradient in operation place etc., precision greatly reduces; And also have a kind of weighing device of axial pin type sensor, and though overcome influence such as oily temperature, can not overcome the influence of swing arm hoisting acceleration and the influence of the operation place gradient, when when these operating modes are weighed, the precision of this weighing device greatly reduces too.We by experiment, the gradient of every increase by 1%, weighing precision descends 1%.If when being stained with remaining material on the scraper bowl of shovel loader, also can influence weighing precision.Facts have proved that the weighing precision of loader weighing apparatus is subjected to the influence of measuring point very big.
Summary of the invention
The purpose of this utility model is that a kind of shovel loader intelligent weighing device is provided.The measuring point of this device is suitable, is not subjected to the influence of swing arm acceleration, the place gradient and leftover materials during work, can guarantee high-precision measurement and weighing precision.
The technical solution of the utility model.Shovel loader intelligent weighing device, it comprises the scraper bowl (1) that is contained in swing arm (2) and shovel loader on each swing arm) be connected in the pin-and-hole (15), or be contained in the drawing and pressing type sensor (4) in the pin-and-hole (16) of being connected of swing arm (2) and swing arm support (3); Front end at swing arm (2) is equipped with near switch (5), stretches out height 150～300mm place at the boom cylinder piston and is equipped with near switch (6); The output of drawing and pressing type sensor (4) be connected in series near switch 5,6 after be connected to signal processing apparatus.
In the aforesaid shovel loader intelligent weighing device, signal processing apparatus comprises signal amplifier (8), v/f voltage-frequency converter (9), central processing unit (10), display (11), printer (12), warning device (13) and data storage device (14) are formed, the signal wire of drawing and pressing type sensor (4) connects the input pin of signal amplifier (8), the output pin of signal amplifier (8) links to each other with v/f voltage-frequency converter (9) input pin, the output pin of v/f voltage-frequency converter (9) links to each other with the data bus of central processing unit (10), the output pin of central processing unit (10) respectively with printer (11), display (12), warning device (13) links to each other with data storage device (14).
Compared with the prior art, the utility model is by installing the drawing and pressing type sensor at suitable measuring point, guaranteed dynamic measurement precision of the present utility model, avoided the influence of ground inclination, acceleration to weighing precision, and by selection near the position of the switch, it is best that the measurement data that the drawing and pressing type sensor is selected reaches, and further guaranteed weighing precision.Therefore, ground inclination, acceleration do not influence weighing precision of the present utility model at all, but also have solved in the prior art, and loading shovel unloading back influences the problem of weighing precision because the viscosity of material is bonded on the bucket.
