中文摘要:针对家禽在悬挂输送过程中的在线称量需求,提出一种家禽在线称量方法。通过对家禽宰杀用悬挂链输送机牵引链的受力分析,建立牵引张力的力学模型,采用不同称量高度的方法,估算出链条牵引张力,再根据牵引张力计算出被称量物体的质量。仿真结果显示,通过仿真估算张力的方法计算得到的称量物体质量,偏差在15.7g以内。如果根据测量得到的牵引张力计算得出被称量物体质量,最大误差为125.03g。表明采用根据牵引张力得到被称量物体质量的方法实际可行,在进一步提高测量精度后能够实现家禽的在线称量。

Abstract:An online weighing method for poultry was proposed to meet the demand for online weight grading and weighting of poultry which were carried out on a suspension transportation device. The mechanical model of drawing tension was developed by a force analysis to suspension chain conveyors which was used for butchering the poultry. The method of different weighing heights was proposed to estimate the draw tension of chain and the weight of objects was calculated according to the estimated drawing tension. A weighting test device for the poultry weighting was established. At first, a simulation experiment was carried out and the Matlab and SimMechanics were used to simulate the procedure of online weighting. The results showed that correlation coefficient was 0.99914 between D value and drawing tension, and the object weight deviation from simulating estimation to drawing tension was within 15.7g. Then the experiments were conducted on the same test device and the results showed that correlation coefficient was 0.76 and the correlativity between D value and drawing tension was significant at a significant level of 0.10. The maximum error was 125.03g when the object weight was calculated according to D value. The study suggested that it was realistic to get the object weight on the basis of drawing tension, and the online weighing for poultry carcass could be realized through further improving the measurement accuracy.

Transactions of the Chinese Society for Agriculture Machinery (CSAM), in charged of China Association for Science and Technology (CAST), sponsored by CSAM and Chinese Academy of Agricultural Mechanization Science(CAAMS), started publication in 1957. It is the earliest interdisciplinary journal in Chinese which combines agricultural and engineering. It always closely grasps the development direction of agriculture engineering disciplines and the published papers represent the highest academic level of agriculture engineering in China. Currently, nearly 8,000 papers have been already published. There are around 3,000 papers contributed to the journal each year, but only around 600 of them will be accepted. Transactions of CSAM focuses on a wide range of agricultural machinery, irrigation, electronics, robotics, agro-products engineering, biological energy, agricultural structures and environment and more. Subjects in Transactions of the CSAM have been embodied by many internationally well-known index systems, such as: EI Compendex, CA, CSA, etc.
