In the seed test, in order to obtain the same amount of sample and improve the accuracy and authenticity of the seed test results, it is often necessary to use a sampler to perform precise sample separation before the test. The following introduces several different types of samplers and details their functions and application scope. In general, the sampler can be divided into three types: horizontal format, Zhong Ding type, and electric centrifugal type. We know that there are many kinds of seeds and different types of seeds have relatively large differences in morphology, quality, etc. According to the particle size, they can be divided into three types: large, medium, and small, and for different seed samples, it is better to achieve better results. For sample separation, you need to select a different type of sampler to sample the sampled sample. Horizontal format dividers are generally applied to large-grained seeds and clam-shelled seed samples. Of course, some format dividers are suitable for small-grained seeds. The horizontal format sampler is simple and practical, the grooves are arranged in a row, and the sample is divided into two equal parts by a series of crossed opposite slides; the Zhongding sampler is suitable for the mixing of the particle seed samples and Samples, the instrument is widely used, sampling accuracy and stability are very high, widely used in the field of seed testing; Centrifugal separator is the use of centrifugal force mixing and seed spread on the separation surface for seed sampling, applicable Accurate sampling of all kinds of seeds, grain, and feed, the instrument is highly efficient and very labor-saving, and it is very popular among inspectors. In short, the separation is an indispensable step in the inspection of seeds, grain, feed, etc. The role of the sample splitter is to accurately separate seeds, grains, feed, etc., and serve for the inspection of seeds, etc. During the process of seed inspection, relevant personnel should learn to choose the appropriate sampler correctly and use the sampler to classify the sample accurately, and then to ensure the authenticity of the seed inspection result by improving the sample separation effect. Therefore, the application of the sampler, It plays an important role in checking the effect of seed quality inspection.
1 The electrical system used by the machine
has reliable control performance and strong anti-interference ability.
2 High precision Thrust Ball Bearing and
tapered roller bearing are adopted in the spindle of machine, with high rotary
precision and the large bearing capacity.
3 The machine tool has the function of two
axis linkage, which can be used for turning various types of surfaces.
4 The speed of the worktable adopt two level
of gears, gear reducer and motor with frequency converter to achieve stepless
speed change, very convenient to adjust and operate.
5 The machine feed shaft adopts precision
ball screw and linear guide rail, so that the machine has the characteristics
of high precision and high rigidity.
6 The machine tool is equipped with five
station electric knife, which has the function of automatic knife change.
7 The machine is equipped with large flow
water cooling unit and high-lift pump to ensure good cooling effect.
8 The machine has closed housing (except the top
of the slide), and the workspace is completely protected by screen seal. It can
also easily open the protective door and is highly accessible when operation.
9 The machine use centralized lubrication,
circular lubrication and other methods, supply oil to each lubricating point,
reduce friction resistance, reduce temperature rise and reduce surface wear..
10 The Z shaft adopts the hydraulic balance oil
cylinder to balance the weight of the slide table and the tool holder. The
balance ability is strong and the stability is good, thus the life of the screw
and the guide rail can be improved.
11 The operation procedures of the machine are
very simple, the degree of automation is high, and the unstable factors of
human error can be reduced to the lowest level.
