Because the potato harvester can complete the crop harvesting machine for potato excavation, separation of soil, paving, picking, picking, collecting and other projects during the potato harvesting process. In the actual production, the selection of suitable equipment can complete the excavation, soil removal, fruit picking, clearing, fruit collection and other projects of the potato at one time. High production efficiency, low operating loss, fast transfer speed, safe and reliable use.
A few days ago, the technicians of the Agricultural and Agricultural Promotion Center of the Agriculture and Animal Husbandry Bureau came to the construction office and the high-yield demonstration area of ​​the potato 10,000 mu to learn about the planting and harvesting of the potato this year. 
In the 10,000-mu high-yield creation demonstration area, along with the roar of the harvester, the potato rolled into the dump truck car that followed. In a blink of an eye, the potatoes that were still in the ditch were transported in batches to the branching area. Different from the past, in the past autumn season, groups of workers were seen bending over the earth, manually sorting and spreading the potatoes scattered in the ground. In addition to the two new potato harvesters and dump trucks in this year's land, almost no other people can be seen. This advanced machine and equipment instead of manual means not only reduces the labor intensity of workers, but also greatly improves the work. effectiveness.
Some commonly used metal alloy powders for thermal spray include:
1. Nickel-based alloys: These alloys are known for their excellent corrosion resistance and high-temperature strength. They are often used in applications where resistance to oxidation and wear is required, such as in gas turbine components.
2. Cobalt-based alloys: Cobalt alloys are known for their high hardness and wear resistance. They are commonly used in applications where resistance to abrasive wear and high temperatures is required, such as in the aerospace and power generation industries.
3. Stainless steel alloys: Stainless steel alloys are used for their corrosion resistance and high-temperature strength. They are often used in applications where protection against corrosion and oxidation is required, such as in chemical processing equipment.
4. Titanium-based alloys: Titanium alloys are lightweight and have excellent corrosion resistance. They are commonly used in applications where a combination of high strength, low density, and corrosion resistance is required, such as in the aerospace industry.
These metal alloy powders can be applied using various thermal spray techniques, such as flame spraying, arc spraying, plasma spraying, or high-velocity oxygen fuel (HVOF) spraying. The specific choice of alloy powder and thermal spray process depends on the desired coating properties and the application requirements.
China's development of mechanization of potato production must also "add fire"
[China Agricultural Machinery Network Industry News] The potato harvester produced in China is an irreplaceable power tool in agricultural production. Especially in recent years, the potato harvester has been recognized by the majority of farmers.
China's development of mechanization of potato production must also "add fire"
In the potato branching area, a hot-spot work scene, the dump truck pours the whole potato into the tiller, after the initial screening, the soil, potato mash and other impurities and unqualified potatoes are screened out, and the qualified commercial potato is followed. The conveyor belt was transported directly by car. This mechanized operation mode not only reduces the labor intensity of workers, but also saves manpower, material resources, and financial resources, and ensures the quality of commercial potatoes and avoids secondary damage to commercial potatoes.
The development status of potato harvester in China at the present stage
In the Chinese market, the potato market has been in a stage of rapid development. It can be seen from the support of the Chinese government for agricultural policies. The time centered on industry has led me to a stage of rapid development of the economy for a long time. However, this stage has also brought huge environmental problems to China's economic construction. Under the premise of facing environmental and economic problems, our government has begun to strengthen the development of the agricultural economy. At this time, the development of economic crops in agriculture has become a key development link.
In response to the current state of use of equipment in China, the government and professionals in China have carried out reforms in the use of agricultural equipment, and introduced a series of preferential policies to improve the promotion and use of agricultural equipment in China as soon as possible, in response to the use of agricultural equipment in China. People inside and outside the industry conducted research and put forward their own suggestions. Let's take a look at the development status of the potato harvester.
In the current economic environment, the development of agricultural potato harvesters in China should be continuously combined with the rural market to ensure the use rate of equipment. The equipment should be continuously used in cooperation with relevant technical research units to apply more technologies to the equipment. In the government, the government should increase the financial subsidy policy in the use of potato equipment. The research and development of China's equipment must keep up with the development trend of the current era, save energy and reduce environmental consumption, and actively develop high-precision equipment.
Potato harvester makes agricultural machinery abundance
For a long time, the integration of agricultural machinery and agronomy between the “brothers†has been regarded as an important bottleneck in the development of mechanization of potato production. In this regard, the professor of the Agricultural Machinery Engineering Science Institute said that “the integration of agricultural machinery and agronomy is not only a national issue, but also a regional issue.â€
In China, the potato planting area is divided into the northeast and north China seasons, the northwest one season area, the southwest one or two season mixed area, the middle two seasons area and the southern winter area. Different geographical factors such as geographical characteristics and planting varieties make the specific problems that need to be solved in each region. Therefore, it does not mean that the contradiction between a certain local agricultural machinery and agronomy is solved one-sidedly. “For example, the northeast and north China are flat, with large plots, wide rows, and ridges, and the speed of enterprise planting is fast, and the mechanization level is high. More than 70% of the northwest is hillside, the plot is small, and the farmland is small. The infrastructure is poor, the planting mode is large, and the farming methods are extensive. Most of them need small and medium-sized machinery. The mountainous areas in the southwest are mostly, the plots are small and scattered, some of the larger dam areas are rich in planting patterns, the farming is relatively extensive, and the mechanization level is low. Potatoes are planted in winter paddy fields, with small plots and heavy soils. Most of them use ridges or stalks. At present, they are mainly based on manual operations. The same machine may not be suitable in different places.
In the case of potato harvesting, there are mainly two methods of combined harvesting and segmented harvesting. In general, combined harvesting is considered to be a highly mechanized harvesting method. However, joint harvesting is not applicable in the northeastern region where the mechanization is relatively high. Due to the soil viscosity in the area, the vibrating device of the combine harvester could not shake the mud on the potato chips. If the strength is too large, it will cause the inside of the potato to rupture, forming a water core, causing internal decay, which will quickly spread to other potatoes. Therefore, the specific analysis of the specific problems of potato mechanization is developed.
Due to the geographical and climatic differences between different regions, it is difficult to promote and expand into other regions, and the products are highly personalized, making it difficult to mass-produce and sell. It can be seen that to improve the mechanization level of potato, we must not blindly pursue the growth of digital, but should improve the quality of mechanized production, and develop and manufacture machinery suitable for potato production in different regions, so that agricultural machinery and agronomy can be truly integrated. together.
It is understood that Jiaozhou City combines the improvement of mechanization of potato production with the implementation of the subsidy policy for the purchase of agricultural machinery. In the past three years, the subsidies for the purchase of agricultural machinery for potato production have reached more than 200,000 yuan, spurring farmers to invest nearly 1 million yuan to promote various types of potato production. More than 130 sets of machinery. At present, the city has built 5 demonstration bases for potato production mechanization, and the number of potato production machinery has reached 1,200 sets. The mechanization level of potato machine production has reached 70%.
However, the level of mechanization of potato production in most areas of China is relatively low. Liu Xian, the former head of the Agricultural Machinery Development and Extension Station of the Ministry of Agriculture, pointed out that the state should increase support, further enhance the important strategic position of potato mechanization, and formulate and implement the promotion of potato mechanization. (Supplement) policy to strengthen the development of the potato market. Taking the mechanized sowing and harvesting of weak potato as a breakthrough, we will strengthen the introduction, digestion and re-innovation of foreign advanced technology and equipment, research and development, manufacturing machine coordination, functional integration, full-scale standardization, and operation of potato mechanized technical equipment. In contrast to the mechanization of the whole process of the potato, a complete standard system and a full mechanized technical route were established, and a machine tooling scheme was proposed.
