Problems solved by technology

According to incomplete statistics, more than 80% of the soil-contacting parts of agricultural machinery are scrapped due to the failure of abrasive wear, which seriously affects the quality and efficiency of work and increases the cost of work. At the same time, frequent replacement of failed knives will increase labor intensity and delay farming time.
The main failure forms of the rotary tiller are fracture and wear, especially wear. As the main working part of agricultural machinery, although the cost is not high, the reliability of the equipment is reduced due to its easy wear and replacement. and work efficiency, increased equipment use and maintenance costs, those skilled in the art urgently need to develop a treatment method to improve the surface strength and wear resistance of the rotary tiller

Embodiment 1

[0027](1) Clean and dry the rotary tiller, clean and dry the rotary tiller, move the grinder to the surface of the rotary tiller at an angle of 5°, and move the grinder to the right, 1 / 4 of the upper left of the impeller of the grinder Align the surface of the rotary tiller, and face the front of the rotating grinding wheel to the surface. The area between the grinding marks is 50% of the rotary tiller, and the rotation speed is 4000rpm. Use No. 50 sandpaper to smooth the burrs, convex points and deep scratches. Then wash it 4 times with deionized water and dry it; (2) Put the cleaned and dried rotary tiller in a salt bath with a salt bath temperature of 750°C and a holding time of 6 hours. The mass ratio is as follows: urea: sodium carbonate, potassium chloride: diboron trioxide = 9:5:3:2; (1) urea is dried at 120°C, and boric acid is prepared from boric acid at 350- Melt at 400°C until gelatinous, and break into small pieces after cooling. Mix potassium chloride and sodium c...

Embodiment 2

[0030] (1) Clean and dry the rotary tiller, move the grinder to the surface of the rotary tiller at an angle of 10°, move the grinder to the right, align the upper left 1 / 4 of the impeller of the grinder with the surface of the rotary tiller, and rotate The front of the grinding wheel facing the surface, the coverage area between the grinding marks is 60% of the rotary tiller, the rotation speed is 4500rpm, and the burrs, convex points and deep scratches are smoothed with No. 50 sandpaper, and then cleaned 4 times with deionized water. (2) Place the cleaned and dried rotary tiller in a salt bath with a salt bath temperature of 750°C and a holding time of 6 hours. The mass ratio of the three-component co-infiltration salt bath is as follows: urea: sodium carbonate, Potassium chloride: boron trioxide = 9:5:3:2; (1) urea is dried at 120°C, and the preparation of boron trioxide is to melt boric acid at 350-400°C until gelatinous, After cooling, it is broken into small pieces.

Abstract

The invention belongs to the technical field of rotary blade processing, and particularly relates to a treatment process method for improving surface strength and wear resistance of a rotary blade, which adopts the combination of heat treatment, wear-resistant coating spraying and co-permeation processes, the treatment method is simple and low in cost, capable of enabling the rotary blade not to be broken and bent, wear-resistant, greatly reducing the load of a tractor, strong in soil crushing capability, high in sharpness, high in abrasion resistance, environmentally friendly and the like, can meet the requirement of intensive tillage, shortens the process interval, reduces the replacement frequency of the rotary blade and improves the working efficiency. The strength is high and the toughness is good. The rotary blade is wear-resistant, and cannot be broken and bent when touching 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 processing method for improving the surface strength and wear resistance of the rotary tiller blade. Background technique [0002] Rotary tiller Rotary tiller, also known as rotary tiller, is a driven soil tillage machine with rotating cutter teeth as the working part. It is a tiller that is matched with a tractor to complete plowing and harrowing operations, and belongs to the soil preparation machine in agricultural machinery. Its performance is characterized by strong soil crushing ability. One rotary tillage can achieve the soil crushing effect of several times of general plowing and raking operations. It is not only suitable for dry farming and hydroponics in farmland, but also suitable for shallow cultivation and covering of saline-alkali land to inhibit the rise of salinity. It can complete operations such as stubble weeding, overturning and coveri...
