(1) The first tractor in China was produced in an acre of land in the pear garden of which university?

1In July, 958, the first red "Dongfanghong" 54 crawler tractor was produced in New China. According to the memories of the old workers, they hung Chairman Mao's head on the front of the first Dongfanghong tractor, dressed the tractor like a bride, put on big red flowers, and covered the body with colorful silk.

Knocking gongs and dancing flags, happily following the tractor "boomed ..." and opened the door of Yi Tuo factory. New China construction talents gathered in Luoyang from all directions of the motherland. Under the harsh construction environment and living conditions at that time, with a hundred times of efforts and a thousand times of courage, they just produced the first tractor in New China one year ahead of schedule, creating a much-told story in the history of agricultural machinery construction.

The Origin of "Dongfanghong"

The name of Type 54 tractor produced by China No.1 Tractor Factory is also very interesting.

According to Comrade Su Yuan, then the first propaganda minister and deputy secretary of the Party Committee of Yi Tuo, the first tractor was still being produced at the beginning of 1958. Yi Tuo specially organized engineers to compile a product manual named "D T 54 Tractor" to introduce the performance, use, driving, repair and maintenance of tractor components.

Shortly after the publication of this book, Yi Tuo Factory received an important instruction from Chairman * * *: "Don't use foreign characters for tractor models and names." So, Yi Tuo began to mobilize all the staff to name the tractor. At the same time, relevant ministries and commissions of the Central Committee and relevant units in Luoyang City were mobilized, and everyone named the tractors produced in New China.

First of all, the Automobile Industry Administration of the First Machinery Department nominated "Iron Bull". After discussion, the Party Committee of Yi Tuo Factory was dissatisfied with this name, and later gave it to the 27 horsepower wheeled tractor produced by Tianjin Tractor Factory.

Later, there were names with local characteristics such as Longmen and Baima in Luoyang, because there are famous cultural relics and historic sites such as Longmen Grottoes and Baima Temple in Luoyang. After the name of "White Horse" was put forward, several workers in Yi Tuo stamping workshop specially designed a "White Horse" nameplate. The white horse in this nameplate faces left and its hooves run hard. However, the names "White Horse" and "Longmen" are not unique to Luoyang, and employees feel that a delay cannot represent a delay.

The next day, An Daoping, then deputy director of the office of Yi Tuo Factory, went to Luoyang to discuss the naming of tractors with relevant responsible persons. Just when he came back fruitlessly, he heard someone singing the folk song "Dongfanghong" in the factory: Dongfanghong, the sun is rising, and there is a * * * …… "Dongfanghong" in China! What a beautiful name! It praised Chairman Mao and New China. As a result, this most special name in the history of Chinese trademarks in the future was immediately recognized by all employees in Yi Tuo, and was quickly approved by the First Machinery Department.

Since then, three striking scarlet letters of "Dongfanghong" have appeared on all tractors made in Yi Tuo. The Type 54 crawler tractor produced in Yi Tuo has finally got a resounding and proud China name.

⑦ What are the functions of tractors?

Hello tractor comes from Latin trahere, which means "pull". It is a device used to drag other devices that can't move by themselves. Generally speaking, it is a vehicle used to tow and pull other vehicles or equipment. In British English, tractors refer to tractors used in agriculture. Directory [hidden] [edited] Agricultural tractors are most commonly used to describe vehicles used on farms. Agricultural tractors are used to pull agricultural machinery or trailers for farming, harvesting or other similar tasks. In19th century and early 20th century, the earliest mechanized agricultural equipment was steam tractor. They use a steam engine, which is low in safety and easy to explode, confusing drivers and using a crawler drive. Due to the use of internal combustion engines, these machines were eliminated in the 1920s. Modern agricultural tractors usually have four pedals for drivers to manipulate. The pedal on the left is used to operate the clutch. The driver depresses this pedal to disengage the gearbox in order to shift gears or stop the tractor. The two pedals on the right are used to brake the left and right rear wheels respectively. In rear-wheel drive vehicles, this method can increase the steering angle of the vehicle. This is often the case when turning sharply; Similarly, when driving in muddy or soft soil, vehicles often slip, so they will also be used. The driver stepped on both pedals to stop the tractor. When the four-wheel drive tractor runs at a certain speed, the tractor is stopped by engaging the four-wheel locking differential.

Attending what is tractor skidding?

The operation of collecting wood scattered in woodland to cutting area by tractor. This is a widely used mechanized skidding method.

develop

Tractors were first used for skidding in California from 65438 to 0890. At that time, it was an agricultural tractor, driven by steam and with iron wheels. In the 20th century, with the appearance of internal combustion engine, tractors were gradually improved to be driven by internal combustion engine, and developed into crawler type and pneumatic tire type. Later, winches and arches were added to tractors, and their cables were used to collect and haul wood. Soviet Union 1932 to 1933 adopted tractor skidding, and 1948 adopted special tractor skidding equipped with winch and loading plate. In the early 1950s, China first began to use tractor skidding in the northeast forest region. The tractors used at that time were KT- 12 skidding tractors and C-80 agricultural tractors imported from the Soviet Union. Starting from 1964, J-50 crawler tractor and J-80 wheeled folding tractor are manufactured by ourselves. Tractors are flexible, not limited by direction and distance, and can drive near the wood to be collected, and use the steel cable on its winch to twist the wood to the tractor without stacking. However, when skidding, it is necessary to drive along the skidding path many times, which is easy to destroy the woodland and damage the young trees. Suitable for skidding in forest areas with slope below 25, clear cutting or selective cutting. The sliding distance usually does not exceed 1000 meters.

Tractor skidding way

It can be divided into four types: full towing, semi-trailer, semi-trailer and full load.

Full trailer skidding

The wood is tied to the tractor's traction hook with a special rope or hook, and the wood is completely dragged on the ground when the tractor runs. Suitable for log skidding with flat terrain and diameter class generally not exceeding 50 cm. Because the front end of wood is easily blocked by obstacles such as cut roots and rocks in the process of skidding, the running resistance is great, so the front end of wood can be supported by inclined pallets or covered with a funnel-shaped iron cap.

Semi-loaded and semi-suspended skidding

When skidding, the front end of wood is hoisted or lifted off the ground with special ropes or grapples, and the back end is dragged on the ground. The front end of semi-loaded wood is installed on the loading plate of tractor (figure 1).

Figure 1 The front end of semi-suspended wood is suspended under the arch or hanger at the rear of the tractor (Figure 2). This way has little running resistance and is easy to pass through obstacles, so it is the main way for tractors to collect sliver at present. In semi-suspended skidding, the front end of the wood is hung on the arch behind the tractor. When semi-trailer skidding, the small head of the original strip faces forward, and when semi-trailer skidding, the big head faces forward. Since the 1960s, some countries have developed skidding tractors with grappling hooks, which replace tying wooden ropes with grappling hooks, thus eliminating the tying process (Figure 3) and improving production efficiency. This skidding tractor is usually used in conjunction with skidding return stacker.

Figure 2

Figure 3 Full-load taxi

The wood is completely loaded on the tractor or its traction bracket. With hydraulic lifting arm, it is towed by tractor or carried by car. This method is mostly used for skidding short logs, such as pulp wood, in northern Europe and North America. It is also used in some forest areas in the south of China, such as pulling a small trailer with a walking tractor.

Selection of skidding track

Tractor skidding roads are divided into main roads and branch roads. Main roads should be located in areas with concentrated wood, solid soil and less construction workload, and the skidding distance should be shortened as much as possible. In areas with a slope of less than 8, the main road can be set along the mountain, and the branch road can be set on the inclined mountain. When the slope is about 10, the main road is set on the inclined mountain, and the branch roads are set along the mountain. Panshan Road can be set in steep slope. In the valley area, the main road can be set along the bottom of the valley, and the two slopes can be set with branches. When the ditch bottom is wide and the two slopes are long, two main roads can be set along each slope bottom. The skidding track should try to avoid mother and young trees and areas that are prone to soil erosion. The main road is 3 ~ 4.5m wide and the minimum curve radius is 35 ~ 40m. Branches extend from two sides or one side of the main road to all parts of the cutting area, with a width of 3-3.5 meters and a minimum curve radius of 25-30 meters. The spacing is generally 50 ~ 70 meters when skidding on both sides and 30 ~ 45 meters when skidding on one side.

Tractor skidding has become the most widely used mechanized skidding method in the world because of its flexibility and other advantages. With the continuous improvement of skidding tractor structure, the application scope of tractor skidding is also expanding.
