84993749 Cylinder Spike Tooth For Combine Harvesters Concave

Introduction

The cylinder spike tooth is a key component in agricultural machinery, particularly in combine harvesters. It plays an important role in the threshing and separating of crops. The spike tooth is a type of projection that is attached to the cylinder or drum in the thresher, which helps to separate the grains from the straw. The spike tooth is designed to penetrate deep into the crop and rip it apart, allowing the grain to be separated.

Applications

The Cylinder Spike Tooth is commonly used in combine harvesters and is installed on the threshing cylinder. It can also be used on other agricultural machinery where crop threshing is required.

Compatibility

The 84993749 Cylinder Spike Tooth is compatible with various brands and models of combine harvesters. Below is a list of some compatible machinery:

In addition to the Cylinder Spike Tooth, we also offer a wide range of other agricultural machinery parts including agricultural chains, agricultural gearbox, pulley, sprocket, coupling, pto shaft, concave, and more.

Signs You Need to Replace the Cylinder Spike Tooth

There are several signs that indicate you need to replace the Cylinder Spike Tooth:

1. Decreased threshing efficiency: If you notice that the threshing efficiency has decreased, meaning that the grain is not being effectively separated from the straw, and there is increased grain loss or leftover grain in the straw. This could mean that the spike tooth has worn down and is no longer able to provide enough cutting and separating force.
2. Significant wear: Check the spike tooth for fracture, missing pieces, significant wear, deformation, or dullness. If the height has significantly decreased, it means that the spike tooth or cylinder has reached the end of its useful life and needs to be replaced.
3. Foreign object damage: If you have sucked in stones, metal fragments, or other hard foreign objects during operation, it may cause the spike tooth to break or damage, which will severely affect the threshing function and require the damaged spike tooth to be replaced immediately.
4. Abnormal noise: If you hear abnormal noises from the thresher during operation, it may be caused by abnormal contact or collision between damaged spike teeth and other components.
5. Increase in power consumption: Due to spike tooth wear, the machine may require more power to achieve the same threshing effect, resulting in increased engine load or fuel consumption.

How to Choose the Right Cylinder Spike Tooth

When selecting a Cylinder Spike Tooth, here are some factors to consider:

1. Crop type: Different types of crops have different requirements for spike teeth. For example, for crops with small grains and soft straw such as wheat or rice, spike teeth that are more suitable for fine threshing should be selected. For crops with large grains and hard straw like corn, spike teeth that are more durable and have stronger penetration force should be chosen.
2. Spike tooth shape and arrangement: Spike teeth come in various shapes, including straight, slanted, curved, etc. Each has its specific applications. Density of arrangement also affects the threshing efficiency and the degree of damage to crops. Generally, high-density arrangement is suitable for fine threshing, while low-density arrangement is beneficial for reducing straw damage.
3. Material and hardness: Spike tooth material must be wear-resistant, corrosion-resistant, and have certain toughness to ensure long-term stable performance. The choice of hardness is also critical. Excessive hardness may cause premature wear or crop damage, while excessive softness will result in faster wear and affect the service life of the spike tooth.
