Problems solved by technology

After World War II, Japan imported rotary tillers from Europe and the United States for agricultural production. However, because Japan mostly has paddy fields, right-angled rotary tillers are not suitable for paddy field farming. A large number of Japanese scholars began to devote themselves to the research and development of rotary tillers for paddy fields. Introduced the rotary tillage scimitar, and successfully solved the problems of the knife shaft following the grass
According to incomplete statistics, more than 80% of the soil-contacting parts of agricultural machinery are scrapped due to abrasive wear. The early failure of soil-contacting parts of agricultural machinery seriously affects the quality and efficiency of the operation, increases the operation cost, and frequently replaces the invalid tool. It also increases labor intensity, Delay in farming time

Embodiment 1

[0021] A treatment method for improving the abrasion resistance and toughness of a rotary tiller, the specific method is as follows:

[0022] (1) Grind the rotary cultivator with a sand mill for 27s, the speed is 2500r / min, the sanding is rotating forward, the sharpening frequency is 60 times / min, the mass fraction is 4% water-based coolant to aid grinding, the grinding pressure 150N, then cross-polished with water sandpaper with a particle size of 600 mesh at a 45° angle for 2 minutes, washed with deionized water for 4 times, and then put in ethyl diaminopropyl trimethoxy methacrylate with a weight ratio of 1.43:3.25 and The cleaning agent made of 8% acetic acid solution was ultrasonically treated for 60s, the treatment temperature was 34°C, the ultrasonic power was 200W, the frequency was 50kHz, the insulation was kept for 600s, and deionized water was used to clean twice, and then put into the Soak in an alkaline detergent made of sodium hydroxide and sodium tripolyphosphat...

Embodiment 2

[0032] A treatment method for improving the abrasion resistance and toughness of a rotary tiller, the specific method is as follows:

[0033] (1) Grind the rotary cultivator with a sand mill for 25s, the speed is 2300r / min, the sanding is rotating forward, the sharpening frequency is selected to be 50 times / min, the mass fraction is 3% water-based coolant to aid grinding, and the grinding pressure 140N, then use water sandpaper with a particle size of 400 mesh at a 45° angle to dip in water and cross-polish for 1min, then wash it with deionized water for 3 times, and then put in ethyl diaminopropyl trimethoxysilane methacrylate with a weight ratio of 1.3:3.25 and The cleaning agent made of 8% acetic acid solution was ultrasonically treated for 40s, the treatment temperature was 33°C, the ultrasonic power was 200W, the frequency was 50kHz, the insulation was kept for 580s, and deionized water was used to clean once, and then put into the Soak in an alkaline detergent made of so...

Abstract

The invention belongs to the technical field of metal processing, in particular to a treatment method for improving the abrasion resistance and toughness of a rotary tiller blade. In the technical field of rotary tiller knife processing, the treatment method is simple and low in cost, and can improve the continuous non-bending and durability of the rotary tiller blade. Grinding and greatly reducing the tractor load, strong ability to crush soil, strong sharpness, high wear resistance, green environmental protection and other advantages. It can meet the requirements of intensive cultivation, shorten the working interval, reduce the replacement times of rotary tillage blades, and improve work efficiency. High strength and good toughness. Not only is it wear-resistant, but it will not break or bend when it hits hard objects such as bricks and stones.

Description

technical field [0001] The invention belongs to the technical field of rotary tiller blade processing, in particular to a treatment method for improving the abrasion resistance and toughness of the rotary tiller blade. Background technique [0002] The rotary tiller is a knife-shaped accessory for the rotary tiller used in farmland deflection. There are mainly two types of tillage machines used in the field: conventional plows and rotary tillers. The rotary tiller has the dual functions of plowing and harrowing, and plays an important role in agricultural machinery. The rotary tiller came out in the middle of the 19th century. It was not until the 1920s that Europe successfully developed the right-angled rotary tiller that the rotary tiller was popularized and used in Europe early. After World War II, Japan imported rotary tillers from Europe and the United States for agricultural production. However, because Japan mostly has paddy fields, right-angled rotary tillers are n...
