How to buy a suitable rice harvester? Guide for the selection and purchase of rice harvesters

What kinds of rice harvesters are there? How to choose a rice harvester that suits you? This paper mainly introduces the relevant knowledge that the selection and purchase of rice harvester should pay attention to its mechanical size, feeding mode, walking device, harvesting mode, after-sales service and so on.

Selection of mechanical size

The power of rice combine harvester is generally 9--107kW. Therefore, the size of the selected model should be adapted to the size of the field and the situation of concentrated connection. If the field is flat, the field is large and the height difference is small, you should choose a larger model; if the field is small and scattered, you should choose a small harvester. If a large harvester is selected in a small field, the efficiency of the harvester can not be brought into full play; if a small harvester is selected in a large field, the productivity is low and can not meet the requirements of rapid harvest in the busy season.

Choice of feeding mode

According to the different feeding methods, the rice combine harvester is divided into half-feeding and full-feeding models. The fundamental difference between the two lies in the different treatment of rice straw. In the semi-feeding model, only the panicle enters the threshing device during rice threshing, which basically keeps the straw intact. The stubble of this model is lower, usually at 6muri 10cm. The straw conveying device of this type is more complex, the price is high, and there are many faults.

All feed the machine, straw and ear are all fed into the threshing device. After being hit by the drum, the straw was interrupted and chopped into a mess and discharged in the field. In order to reduce the load of the threshing drum, the stubble is generally left higher, at 10murmur20cm. The model has the advantages of simple structure, good reliability, few faults and relatively low price. Buyers should make a reasonable choice according to the local characteristics and actual situation.

Selection of walking devices

There are two kinds of walking devices of rice combine harvester: wheeled and rubber crawler. The wheeled walking device has mature structure and wide versatility. However, the tire grounding area is small, when working in the paddy field, the subsidence is deeper, it is difficult to turn and walk, and the damage to the surface soil is more serious. It is suitable for use in areas where the field is dry and the soil is hard and not easy to sink. The tracked harvester has a large crawler grounding area and a shallow sinking depth during operation, so the general rice fields can work normally.

Therefore, machine buyers should choose harvesting machinery according to the soil properties and production habits of the local paddy field. For sandy and semi-sandy soil, the bearing capacity is strong, so the harvester with wheeled walking device can be selected. For viscous and semi-clayey soil, it is appropriate to choose the harvester with crawler walking device.

In addition, the knapsack harvester of the wheeled walking device can be unloaded when the farm is idle, and the tractor can be engaged in transport operations; when the farmers are busy, they can also be equipped with ploughs, rakes or rotary tillers for farmland operations. The main engine has the advantages of multi-purpose, high utilization rate and good economic benefit. The harvester of crawler walking device is a special harvester with low utilization rate. In the selection and purchase, the buyer should also consider carefully.

The choice of harvest method

Rice combine harvesting, threshing and cleaning are completed at one time, with a high degree of mechanization, and the seeds after cutting are basically clean, which should be given priority. Due to the limitation of economic conditions and the influence of traditional harvesting methods, some areas have long been accustomed to harvesting first, drying in the sun and then threshing, so we can consider choosing a rice cutting machine.

Select mature rice combine harvester

It is best to choose and buy models introduced by the local agricultural machinery promotion department and tested and demonstrated locally, which have proved to be reliable in quality and suitable for local use. At the same time, we should also pay attention to understand the brand reputation of the model and the after-sales service ability of the production enterprise. Do not buy rice combine harvesters of poor quality and unguaranteed after-sales service.
