[0033] The present invention distinguishes between indoor and outdoor applications when in use; when used indoors, such as in a warehouse or a laboratory, because the first infrared distance sensor 29 and the second external distance sensor 31 are less disturbed by the external environment in the indoor environment, the accuracy of the measurement can be guaranteed, and the first infrared distance sensor 29 and the second external distance sensor 31 are mainly used to measure the wrapped forage, while the first measurement scale rod 27 and the second measurement scale rod 30 are mainly used for sensor alignment. In actual operation, the wrapped forage to be measured is placed on the loading plate 11, and the wrapped forage is kept at the center of the loading plate 11 as much as possible; then the cantilever support rod 3 is rotated, and when the cross-shaped support frame 4 is located directly above the wrapped forage, the corresponding first top screw 20 is tightened, and the cantilever support rod 3 is relatively fixed at this time; then the adjusting nut 15 is rotated through the operating rod 18 to move the adjusting screw 14 down to the appropriate position; then the cross-shaped support frame 4 is appropriately rotated to keep the first measurement scale rod 27 as vertical as possible to the surface of the wrapped forage to be measured, and then the second top screw 28 is tightened, At this time, the cross-shaped support frame 4 is relatively fixed; then the second measuring scale rod 30 is inserted into the hollow shaft, and the end of the second measuring scale rod 30 is positioned as close to the geometric center of the upper end surface of the wrapped grass as possible; then the end of the first measuring scale rod 27 is supported on the wrapped grass, and the height of the first measuring scale rod 27 is controlled by adjusting the nut 15, so that the end of the first measuring scale rod 27 is positioned as close to the geometric center of the wrapped grass as possible; finally, the first infrared ranging sensor 29 and the second external ranging sensor 31 are controlled by a computer to periodically measure the expansion change of the wrapped grass.

[0034] In outdoor applications, for example, measuring the expansion change of wrapped hay when it is stored outdoors, the first infrared distance sensor 29 and the second external distance sensor 31 may be interfered by the outdoor environment, causing data errors. Therefore, in actual measurement, the first infrared distance sensor 29 and the second external distance sensor 31 are used as the main measurement, and the first measurement scale rod 27 and the second measurement scale rod 30 are used as the auxiliary measurement. The measurement data of the first measurement scale rod 27 and the second measurement scale rod 30 are used to correct the measurement data of the first infrared distance sensor 29 and the second external distance sensor 31, thereby maintaining the accuracy of the final measurement result. The actual operation process is the same as the operation in indoor applications; the first measurement scale rod 27 and the second measurement scale rod 30 are provided with a metering scale, and the data is read by relying on the second guide sleeve 26 and the end of the hollow shaft 6 as a reference, respectively. The data read at regular intervals is compared with the data on the computer. If the error is within a reasonable range, the computer value shall prevail. If the error exceeds the reasonable range, the value of the measurement scale rod shall prevail.

[0035] When measuring the weight of wrapped hay: measure the weight of the wrapped hay and prepare a counterweight of corresponding weight; use the operating method for indoor application to make the cross-shaped support frame 4 in an appropriate position; remove or cancel the use of the second measuring scale rod 30, insert the slide bar 8 into the hollow shaft 6, and connect the bottom end to the extrusion plate 9, and the extrusion plate 9 presses the top of the wrapped hay; measure and record the wrapped hay data in the initial state; then place the counterweight on the load-bearing plate 10 and keep placing it slowly; finally, obtain the corresponding data according to the test requirements.
