Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] The present invention provides a technical solution: Figure 1 - Figure 9 As shown, a loader electronic scale calibration device includes a vehicle body 1, a vehicle body 1, and a loading frame 101 is provided at the front end of the vehicle body 1. A loading hydraulic rod 102 for controlling the rotation and lifting of the loading bucket is provided on the loading frame 101, and a connecting pipe 105 is provided between the loading hydraulic rods 102. A hydraulic pipe 104 is fixedly installed on the side end of the connecting pipe 105, and a hydraulic box 103 for controlling the lifting of the loading hydraulic rod 102 is provided at one end of the hydraulic pipe 104 away from the loading hydraulic rod 102. The above-mentioned hydraulic box 103 is provided with a hydraulic pump and other devices to provide power for the extension and contraction of the loading hydraulic rod 102. A weighing mechanism 2 for weighing the loader and the weight of the cargo unloaded by the bucket is provided inside the wheel shock absorber of the vehicle body 1 and the loading frame 101 near the connecting pipe 105. A calibration adjustment mechanism 3 for calibrating and adjusting the electronic scale is provided in the cab of the vehicle body 1. When the bucket is lifted, the oil pressure of the hydraulic system will increase with the increase of the weight of the material. The pressure value is measured by the pressure sensor, and combined with the force-bearing area of ​​the cylinder, the gravity of the material can be calculated. The calculation formula is: P= ; Where A is the effective area of ​​the hydraulic cylinder, and F is the force borne by the hydraulic cylinder, including the weight of the material, the weight of the bucket, friction resistance, etc. The calculation formula is: F=G0+G1+G2; Where G0 is the weight of the material. After loading and unloading, the weight of the unloaded material G0 is calculated using the following formula: G0=F1-F2, where F1 is the force exerted on the hydraulic cylinder when loaded with goods, and F2 is the force exerted on the hydraulic cylinder after unloading. G1 is the bucket's own weight, and G1 is a fixed data; G2 is the gravity effect of the tilt angle of the loader on the material. The calculation formula of G2 is: G2=G1x , The angle gravity data deviation of the loading vehicle is calculated by the relative hydraulic pressure difference of the relative lifting of the loading hydraulic rod 102, Thus, the electronic scale calculates the weight of the loaded goods, and after the first loading and unloading, the partial residual goods weight is G3, and after the second loading of the material, the unloaded material F2 is the self weight G1 of the bucket plus the residual material weight G3, so that F2=G0+G1+G3, and the second detection of the loading material gravity data calculation formula is G0=F1-G0+G1+G3, and the present application checks and weighs the overall weight of the vehicle body through the weighing mechanism 2, subtracts the overall weight of the vehicle body after the unloaded material from the weighing data of the reloaded material, obtains the weight of the unloaded material, and at the same time calculates the weight of the material through the change of the hydraulic pressure after lifting and unloading the material by the loading hydraulic rod 102, compares the two kinds of measured material weights, thereby reducing the difference between the measured material weights, making the measurement of the material by the electronic scale more accurate, and finally, when the overall weight changes after the first weighing, the calibration and adjustment mechanism 3 is used to calibrate the weighing data of the electronic scale, thereby making the calibration and adjustment work of the subsequent loading weighing more convenient after single loading weighing.

Specifically, when the limiting rod 307 no longer presses the fixed sliding block 208, the adjusting magnetic ring 309 installed on the lower end of the brush ring 206 moves under the magnetic field of the calibration magnetic ring 308, so that the brush ring 206 is driven to move. After the calibration magnetic ring 308 and the adjusting magnetic ring 309 are adsorbed and attached, the data is calibrated to zero, so that the staff can calibrate the electronic scale more conveniently.

[0025] Working principle: when the material loaded in the loading vehicle needs to be weighed, the weight of the material in the vehicle-mounted hopper is the total weight minus the fixed data of the self-weight of the vehicle body, and the weight of the poured material is G0. Through the above formula G0=F1-F2, F1 is the force borne by the hydraulic cylinder when loading the goods, and F2 is the force borne by the hydraulic cylinder after unloading. The weight of the poured material is calculated, and the weight of the material is calculated through the change of the hydraulic pressure after lifting and unloading the material by the loading hydraulic rod 102. By comparing the two kinds of measured material weight, the difference between the measured material weight is reduced, so that the electronic scale can measure the material more accurately. When the staff needs to calibrate the electronic scale after loading, the driver pushes the control block 313 to make the control telescopic rod 312 contract. The liquid in the control telescopic rod 312 is transmitted to the connecting pipe 304 through the adjusting pipe 303, and then transmitted to the water passing block 314 through the three-way pipe 305. The liquid is transmitted to the adjusting telescopic rod 311 through the water passing block 314, so that the adjusting telescopic rod 311 starts to elongate. The adjusting telescopic rod 311 pushes the limiting rod 307 to start to move, so that the limiting rod 307 no longer presses the sliding block 208. The adjusting magnetic ring 309 installed on the lower end of the brush ring 206 moves under the magnetic field of the calibration magnetic ring 308, so that the brush ring 206 is driven to move. After the calibration magnetic ring 308 and the adjusting magnetic ring 309 are adsorbed and attached, the data is calibrated to zero, so that the staff can calibrate the electronic scale more conveniently.
