A Cylinder spike tooth is a crucial component of agricultural machinery used for separating seeds from crops during harvest. Specifically, it is used as part of the threshing process, where the spike tooth rotates against a drum to separate the seed from the plant material.
Below is a table outlining the specifications of a Cylinder spike tooth:
[ninja_tables id="410474"]The Cylinder spike tooth is typically applied in combine harvesters, which are machines that are used to harvest crops. Specifically, the spike tooth is located in the threshing section of the combine harvester, where it is used to separate grains from the harvested crops.

A Cylinder spike tooth may need to be replaced if any of the following symptoms are observed:
If the combine harvester is not effectively separating the seed from the plant material, causing an increase in grain loss or a large amount of residual grain in the straw, it may be an indication that the spike tooth is worn and no longer providing sufficient cutting and threshing force.
If the spike teeth are found to be broken, missing, severely worn out, deformed, or blunt, or if the height of the spike teeth has significantly decreased, it means that the service life of the spike tooth has come to an end and new spike teeth or the entire Cylinder spike tooth assembly should be replaced.
If the combine harvester inhales stones, metal fragments, or other hard impurities during operation, resulting in spike tooth fracture or damage, which seriously affects the threshing function, the damaged spike teeth should be replaced in time.
If the threshing section of the combine harvester emits abnormal noise during operation, it may be due to the abnormal contact or impact between the damaged spike teeth and other parts.
If the combine harvester is using more power to achieve the same threshing effect than usual, it may be because the spike teeth are worn and the machine requires more power to achieve the same threshing effect, leading to increased engine load or fuel consumption.

When selecting a Cylinder spike tooth, the following factors should be considered:
Different crops have different requirements for spike teeth. For example, for crops such as wheat or rice with small particles and soft straw, spike teeth that are better suited for fine threshing can be selected. For crops such as corn with larger grains and harder straw, spike teeth with greater durability and penetration power are required.
There are various shapes of spike teeth, including straight, oblique, and curved teeth, each with its specific application. The arrangement density also affects the threshing efficiency and the degree of damage to the crops. Generally, high-density arrangements are suitable for fine threshing, while low-density arrangements are beneficial for reducing straw damage.
The material of the spike teeth should have wear resistance, corrosion resistance, and a certain toughness to ensure stable performance under long-term use. The choice of hardness is also critical. Excessive hardness may lead to premature wear or damage to crops, while insufficient hardness may result in faster wear and affect service life.
