Problems solved by technology

However, due to the restriction of the counting speed of the counting machine
Not yet possible
Take sub-packing of corn seeds as an example: the sub-packing specification is 8,000 grains, and the speed of the counting machine is 500 grains / min. It takes about 16 minutes to pack one bag, and the sub-packing speed is too slow to meet the production capacity requirements of the enterprise.

Abstract

The invention relates to a seed weighting system and a weighting method, in particular to a seed weighting system having functions of on-line counting and weight compensating and a weighting method. The weighting system comprises an industrial personal computer, a counting weighting scale, a sampler, a packaging scale, a packager and a selecting scale. The control part of the weighting system is partially networked through a local area network and comprises the counting weighting scale, the packaging scale and the selecting scale which have the function of networking. The industrial personal computer is used as the control center of the whole system to coordinate and control the devices in the system so as to sample, count, calculate the weight of each seed, modify the target weighting ofthe packaging scale and the selecting scale, regulate the control parameter and store the weighting data. The target weight of the packaging scale can be modified through online 'counting and weighting' and acquiring the relationship between the seed number and the weight in real time, thereby realizing the package based on seed number through the weighting method. The invention can solve the problem of singly weighting and standardize the number of each bag of packaged seed.

Description

technical field [0001] The invention relates to a seed weighing system and a weighing method, in particular to a seed weighing system and a weighing method with functions of on-line grain counting and weight compensation. Background technique [0002] Due to the improvement of seed production technology, some seeds (such as: corn) have achieved single seed sowing, and the sowing area and the number of seeds required are fixed. For bags of seeds sold, the number of seeds in each bag is more practical than the weight. [0003] In the traditional method of subpackaging by weight, due to the difference in water content and particle size of the seeds, the weight of the same 1000 seeds varies greatly. Take domestic pioneer seed industry corn seeds as an example: the weight of 1000 grains is about 190g~360g. Corresponding to the metering specification of 8000 grains, the weight range is approximately between 1500g and 3000g. If the simple weighing method is adopted, the number o...
