Expect the crudy of product.In actual production process, the identification of damaged sieve relies primarily on artificial progress, artificial by sampling
Observation or standard screen screening, are judged, its job step is cumbersome, and efficiency is low by observing the particle size of milling product, and not
Meet the demand of the development of modern feed industry.
The breakage of sieve can increase the percent opening of sieve, increase part sieve diameter, reduce the centre-to-centre spacing of sieve aperture, increase
The inhomogeneities of particle powder also weakens the intensity of sieve simultaneously.Particle powder is uneven to cause the hair of feed segregation phenomenon
It is raw, so as to destroy the uniformity of product, while the size of grinding particle size, directly influence the digesting and assimilating of animal, crush cost,
Follow-up equipment is processed and product quality.
The content of the invention
The utility model is intended at least solve one of technical problem in above-mentioned correlation technique to a certain extent.
Therefore, the purpose of this utility model is to provide a kind of sieve damage testing dress based on linear array optical imagery technology
Put, including：
Vibrating material feeding device, for shaking off pellet；
Pellet conveyer, for transmitting pellet；
Optical imaging device, for gathering pellet image, the optical imaging device is placed in pellet transmission dress
Put；Image processing apparatus, for handling collection feedstuff image；Described image processing unit passes through communication interface and optics
Imaging device is connected.
According to the utility model embodiment, the vibrating material feeding device is oscillating feeder, and pellet conveyer is
Conveyer belt, buncher；The buncher is connected by chain with conveyer belt；The conveyer belt is placed under oscillating feeder
Side.
According to the utility model embodiment, the optical imaging device, which includes line-scan digital camera, array light source, light source, to be fixed
Plate, black box；The light source fixed plate, array light source are arranged in black box, and line-scan digital camera is arranged on the top of black box；The linear array
Light source is fixed on the lower section of light source fixed plate, and the line-scan digital camera is fixed on the top of light source fixed plate.
According to the utility model embodiment, described image processing unit is computer.
According to the utility model embodiment, in addition to pellet retracting device, the pellet complete for recovery test.
According to the utility model embodiment, the pellet retracting device is recycling box, and the recycling box, which is arranged on, to be passed
Send the end of band.
According to the utility model embodiment, hopper is provided with above the oscillating feeder.
According to the utility model embodiment, the communication interface is USB data transmission line.
According to the utility model embodiment, the present apparatus utilizes of the sample by sieve after corn and wheat grain crushing
Grain character information judges whether sieve occurs breakage indirectly.
Different from the particulate samples by not damaged sieve, the particle of damaged sieve is generally bigger than normal, crushes in sample
Powder constituents it is less, this be due to sieve occur it is damaged after percent opening increase, particle is not also complete by the impact of hammer leaf
Complete crush just has been discharged by damaged hole, therefore larger by the average area of the sample particle of damaged sieve, and
Particle size distribution is uneven, and it is more discrete that this phenomenon can cause the size of particle to be distributed, therefore area coefficient of variation phase
To also than larger.
The present apparatus utilizes the particle information of damaged sieve, the i.e. average area of particle and particle area variation lines, according to this
Two features judge whether sieve is damaged.
The beneficial effects of the utility model are：The present apparatus utilizes optical image technology, and the damaged quick knowledge of sieve can be achieved
Not with monitoring, accuracy rate is higher, time saving and energy saving, and cost is low.
