What are the main types of combine harvester

This paper gives a general introduction to the knowledge about the main types of combine harvester, the main types of combine are self-walking wheel full-feeding combine, self-walking crawler full-feeding combine, self-walking crawler semi-feeding combine, suspended combine and so on.

What are the main types of combine harvester

The main results are as follows: 1. Self-wheeled full-feeding combine harvester: this type of harvester is more suitable for operation in North China, Northeast, Northwest, Central Plains and dryland, mainly harvesting wheat and rice, and suitable for long-distance transfer. it is the main type of remote harvesting and cross-area operation.

2. Self-walking crawler full-feeding combine harvester: this machine is more suitable for the operation of wet soil in dry land or paddy field in central and southern China, and is suitable for the harvest of wheat and rice crops. Remote harvesting and cross-area operations can be carried out, but if long-distance transfer is carried out, automobile transportation is needed.

3. Self-walking crawler semi-feeding combine: this model is mainly suitable for rice harvesting and wheat harvesting. It is the product with the highest complexity coefficient and the highest price among small and medium-sized combine harvesters. Compared with other models, the grain after harvest has higher cleanliness, and can adapt to the harvesting conditions of deep mud feet and serious lodging, and at the same time ensure the integrity of the stem after harvest.

4. Suspended combine harvester: the suspended combine harvester uses tractor power to harvest and combine operation, which has single power and double power. This kind of model is cheap and can be used for more than one machine, but it is troublesome to disassemble and assemble.

As mentioned above, the use area, harvesting object and operation nature of the combine harvester are important factors to be considered.

Combine harvester is a kind of compound operation machine which integrates the functions of harvesting, threshing, separation, cleaning, grain collection and so on.

It plays an important role in reducing the intensity of agricultural labor, improving productivity, reducing the cost of agricultural production, striving for agricultural time and promoting agricultural harvest. Nowadays, combine harvester through cross-area operation has become an important way and carrier for farmers to increase their income.

Combine can be divided into three types: traction type, self-walking type and knapsack type. A tractive combine is a combine operated by a tractor, which can be divided into two types: self-powered and non-powered. The structure of the tractive combine harvester is relatively simple, but the unit is large and the maneuverability is poor, so it can not open the road by itself and is not suitable for small block operation. The self-propelled combine harvester refers to the combine harvester which is powered by its own engine for walking, harvesting, threshing and cleaning. Compared with the traction combine, the self-propelled combine is characterized by good mobility, self-opening, convenient transfer, high production efficiency, but high cost and low power utilization rate. Knapsack combine (also known as suspended combine) refers to the combine in which the working part of the harvester is suspended on the tractor or general chassis. It basically maintains the advantages of the self-walking type, overcomes the disadvantage of low power utilization rate of the self-walking type, and the cost is low. However, because the overall design is limited by the structure of the tractor, the distance of the conveying mechanism is longer, the cleaning mechanism is shortened, and the transmission is more complex.

According to the feeding mode, the combine harvester can be divided into full feeding type and semi-feeding type. Full-feed combine harvester refers to the combine harvester in which all the grain cut by the cutting table goes into the drum threshing. Most of the combine harvesters for harvesting wheat crops adopt this feeding method, but its disadvantage is that the stalk is incomplete and the power consumption is high. The semi-feeding combine harvester refers to the combine harvester in which the crop cut by the cutting table only enters the threshing drum threshing drum. This model maintains the integrity of the stem and reduces the power consumption of threshing and cleaning. At present, this kind of combined harvester is widely used in southern rice producing areas. However, the transmission mechanism of conveying stalk is complex and the manufacturing cost is high. There is also an ear-picking combine (also known as carding combine), which has been researched and developed in recent years. During the harvest operation, the cutting table only receives grains, threshing first and then cutting the stalks of crops. This structure has high operation efficiency and low power consumption, but the loss rate is relatively high.

First, can be divided according to the amount of feeding (or cutting), can be divided into large, medium and small three types.

Second, according to the walking device, it can be divided into two types: wheel type and track type.

Third, according to the crop name, it can be divided into wheat combine harvester, rice combine harvester, rice-wheat combine harvester, corn combine harvester and so on.

There are many types of combine harvester, at present, the main models used in China are: one is full-feed self-propelled combine, such as Xinjiang-2, Foton Gushen 4LZ-2, Jialian-3060, etc.; the second is full-feeding knapsack combine, such as Guilian-6, Shanghai Ⅲ, etc.; the third is semi-feed self-propelled combine, such as Yangma people, Toyo HL6000C, Kubota-481, etc. In recent years, there is a kind of full-feeding crawler combine which is widely used in the south of China, such as Nantong Wushan-1.5,Huzhou-130,Changchai 4LZ-1.6, Taizhou-150. the work flow of this type of combine is the same as that of full-feed suspended combine, and the walking device is similar to that of semi-feed self-walking combine.
