In the field of agricultural scientific research, especially for seed-related research work, it is often necessary to seed a number of seeds to provide a prescribed number of seeds for the test. The seed counting instrument appears in this context. Its application is to break the drawbacks of the slow, cumbersome, boring, error, etc., in the past, making the inevitable work of counting seeds more simple and accurate.

Since agricultural research experiments are generally rigorous, a basic requirement for the seed counting instrument is that the grain number accuracy is high. For example, in the process of breeding fine varieties, the seeds need to be evaluated, usually measured in terms of grain weight. At this time, it is necessary to count the first 1000 seeds. If the number error of the seed counting instrument is too large, then there will be a large deviation between the measured value of the 1000-grain weight and the true value, and then the seed quality will be correctly evaluated, thus breeding The work is troublesome, so the precision of the seed counting instrument is high, which is a basic requirement.
Secondly, the second requirement of the agricultural scientific research for the seed counting instrument is better in terms of stability and reliability. We know that at present a lot of grain work has already begun to be done using the seed counting instrument. Therefore, to guarantee the result of several grains, the seed is required to be seeded. The stability and reliability of the counting instrument are better. It can't meet the requirement of several grains at the beginning. With the use of the instrument, the error will start to increase, which will inevitably cause measurement error. Therefore, the seed counting instrument Must be stable and reliable, long life.
Finally, there are requirements for the application of the seed counting instrument. It is necessary to know that the types of seeds are various, and agricultural research is often not directed at the development of certain types of seeds. Therefore, in order to increase work efficiency, the number of seeds is increased. The scope of application of the particle analyzer is very necessary, and it is not always possible to use a seed counting instrument for a seed. Therefore, the seed counting instrument must be capable of counting large grain seeds such as rice and wheat, as well as small seeds such as rapeseeds and sesame seeds.
A Chipping Hammer has a blade-type striking surface on one end and a spike point on the opposite end (see Figure 6). A chipping hammer is mainly used to remove slag from welds and to remove concrete from metal surfaces.
Figure 6: Chipping Hammers
Chipping hammer inspection is the same as for hammers in general. In addition, inspect the blade to ensure that it is sharp and not chipped or damaged.
When using a chipping hammer, the work must be properly secured. The chipping hammer is gripped like a normal hammer. The hammer is swung so that the blade strikes the work at a slight angle.
