How to choose a suitable corn combine harvester

With the improvement of our understanding of the economic, social and ecological benefits brought by corn harvesting conservation tillage technology, people have higher and higher requirements for corn harvesting mechanization, and corn harvesters have developed rapidly, followed by a variety of models. How to choose a suitable corn combine harvester has become a concern of farmers. Before answering this question, let's understand the advantages and disadvantages of various models.

According to the different ways of corn harvester and power hitch, it can be divided into traction, suspension (also known as backpack), self-propelled and special corn header harvester used with wheat combine.

1. Traction corn harvester

This model is the earliest one developed and used in China, and generally has 2~3 rows of lateral traction. With the increase of rows, the greater the eccentric traction, the greater the impact on the operation of the machine, equipped with a tractor with 30~60KW power. Its advantages are convenient configuration, simple structure, low price and good reliability. Because the power can be separated from the whole machine, the power machine can be used for other purposes during non-working hours, which improves the utilization rate of the power machine. The disadvantage is that the machine is pulled sideways and needs manual harvesting to clear the way before operation. In addition, the unit is long, the turning radius is large, and it needs open space. In addition, the machine has poor matching with ridge spacing, and it is easy to push down or laterally overwhelm straw.

2. Hanging corn harvester

Hanging corn harvester means hanging the corn harvester on the tractor to make it integrated with the tractor. The form is similar to that of a self-propelled harvester, and there are mainly three types: front suspension, side suspension and inverted suspension. Its advantages are compact overall structure, low price, separation of power from harvester, high power utilization rate, no need for manual harvesting to clear the way, small turning radius and strong adaptability. At present, the front suspension harvester is widely used, which is convenient to configure and conforms to the user's operating habits. The disadvantage is that the structure layout, installation and disassembly of this harvester are troublesome, the driver can't see the header clearly, the weight distribution of the front wheel is too heavy, and the stability is not very good.

3. Self-propelled corn harvester

Self-propelled corn harvester is an advanced harvester. Its advantages are compact structure, perfect performance, high working efficiency and good working quality. The disadvantage is that this model has high cost, resulting in high selling price, long payback period, complex structure and high failure rate. At present, the model has been popularized and used in our province, but it is still in the research and development stage, and there is still a long way to go before it is used on a large scale.

4. Special header for corn

The special header type for corn is to replace the header of wheat combine with the special header for corn, thus transforming the wheat combine into a corn combine. The advantage of this model is that it greatly simplifies the system of corn harvester and improves the utilization rate and economic benefit of wheat harvester. The disadvantage is that when harvesting corn with wheat combine, it is necessary to change the header into a special header for corn, and the separation, separation and cleaning devices of the combine also need to be adjusted and replaced accordingly, which is more troublesome to operate. At present, some enterprises are optimizing the development of this model.
