As one of the three major food crops in China, corn has a long history of planting. Although the country has adjusted the area of corn planting for several years in order to balance the structure of grain cultivation, its planting area has always been in the first place. Although the corn planting area is large, it lags behind wheat and rice in the development of mechanization. According to statistics, in 2018, the wheat machine yield was 98%, the rice machine yield was 89%, and the corn machine yield was only 70%. The degree of mechanization of corn harvest is still the last of the three major food crops.

It can be seen that although starting from 2015, with the implementation of a series of policies such as the national grain planting structure adjustment, supply-side reform, the domestic corn harvester market has entered a three-year downward slump. The demand for harvesting still exists and the inventory is updated, and other factors, the overall corn harvester market in 2018 realized a recovery. According to statistics, during the first four months of 2019, the domestic corn harvester market ’s product sales increased by nearly 18% over the same period. It is still regarded as traditional agricultural machinery products such as large and medium tractors, wheeled wheat harvesters, and tracked rice harvesters The only growth highlight.

There is still a phenomenon of manual harvesting, so the rigid demand for corn harvesting machinery is still there, especially in the Central Plains and hilly areas, there is still a certain amount of incremental market space. After three years of decline in the corn harvester market, the domestic corn harvester companies have launched small corn harvester products targeted at the Central Plains market, grabbing a small number of incremental markets.

Zhengzhou Zhonglian, as an enterprise with a history of more than 20 years in the field of harvesters, has very strong technical accumulation and precipitation. It is reported that Zhengzhou Zhonglian launched the big three rows and big four rows of corn harvesters for the Northeast market as early as 2008. It started to layout the Huanghuaihai market in 2012 and launched the small three rows and small four rows that were harvested incorrectly. Corn harvester. In 2014, 6-row and 7-row corn harvesters were also introduced for the Northwest market. It can be said that Zhengzhou Zhonglian has more than 10 years of technical experience in the field of corn harvesters, and can be regarded as an industry “veteran” with a solid foundation in the field of domestic corn harvesters.

Facing the incremental market of the Central Plains corn harvester, Zhengzhou Zhonglian relies on its own more than ten years of experience in the development and production of corn harvesters. At the same time, the factory is located in Henan Province, the core area of the Central Plains area, and it can be said that it has the right time and place. The “Zhonglian Harvest” 4YZ-3W self-propelled corn harvester launched by Zhongyuan users has been recognized by many users. So what are the characteristics of this “Zhonglian Harvest” 4YZ-3W self-propelled corn harvester?

According to the product research and development staff of Zhengzhou Zhonglian, in order to adapt to the characteristics of small corn plantation in the Central Plains, the “Zhonglian Harvest” 4YZ-3W self-propelled corn harvester has a more compact design, a shorter body and mobility. Strong, small turning radius, more convenient U-turn, so as to achieve higher harvesting efficiency.

And its original cutting head adopts the forced-feeding method of the chain, which can realize no-row harvesting, adapt to various line spacing and agronomic requirements, and can perform horizontal harvesting on the ground. The header picking roller adopts a double-spiral picking roller, which can pull stems quickly, without entanglement and clogging, which greatly improves harvesting efficiency.

In order to achieve a better return to the field, the “Zhonglian Harvest” 4YZ-3W self-propelled corn harvester is equipped with a hob-type pre-pulverizer plus a center-mounted field returner, which can deeply crush the straw into the field. The corn field harvested by this corn harvester has low stubble and high stalk crushing rate. After simple land readjustment, even the next crop can be planted.

The peeling machine adopts 4 groups of 16 rollers, and is equipped with finger-type pressure feeding device. Combined with flexible peeling technology, the peeling rate is high, the damage seed rate is low, the loss is small, and the peeling efficiency is higher. The slide-type grain recovery device can quickly unload the grain, and the use time is short. The elevator hanging plate uses the whole hanging plate, which is more reliable and more durable.

In terms of driving safety, the grain bins, peelers and rear of the 4YZ-3W self-propelled corn harvester of the “Zhonglian Harvest” are equipped with electronic visual monitoring systems, which can visually observe the working conditions, have a clearer vision, and operate more Safety. The elevator and peeling machine are also equipped with a speed alarm device, which can transmit fault information at the first time.

In order to meet the requirements of the new generation of agricultural machinery for the appearance and driving comfort of agricultural machinery equipment, “Zhonglian Harvest” 4YZ-3W self-propelled corn harvester also adopts a new dynamic design, the appearance is more novel and fashionable, and maintenance is more convenient. The overall large-arc glass cab improves the visible environment of the operation, and the cab also reserves an air-conditioning interface, which can be equipped with air-conditioning. The walking system uses a stepless speed change mechanism, which makes the operation and walking operations more convenient.

Of course, in order to satisfy those users who are seeking high configuration, “Zhonglian Harvest” 4YZ-3W self-propelled corn harvester can also be equipped with an integrated display and Beidou navigation system, which can make the engine operating parameters clear. The optional chain lubricating device can automatically lubricate the chain and extend the service life of the chain more conveniently.

Such a “Zhonglian Harvest” 4YZ-3W self-propelled corn harvester that combines various advantages such as reliable quality, high harvesting efficiency, low loss rate, and comfortable operation, especially suitable for corn planting in small plots in Central Plains The harvest must be a good helper for the wealth of the users of the Central Plains corn harvester. It is believed that in the corn harvester market in 2019, this Zhonglian Harvest 4YZ-3W self-propelled corn harvester, which integrates “time, location, and harmony”, will sweep the entire Central Plains region.
