Peanut is not only the world, but also an important economic and oil-bearing crop in China. It is the biggest nut commodity in the world trade, and the trade volume is about 1000000 tons per year. China's peanut planting area accounts for about 1 / 6 of the world's peanut planting area, and the total output accounts for 1 / 3 of the world. It is one of the few international competitive agricultural products in china. The development of peanut production and processing is an urgent need for China to increase agricultural exports and increase farmers' income.
Peanut shelling machine has played an active role in reducing people's labor intensity and productivity, and promoted the development of peanut processing industry. However, the peanut sheller at home and abroad has a high requirement for the rate of peanut crushing and damage, which exceeds the standard of seed and commercialization, and limits the scope of application. Therefore, to reduce the crushing rate and damage rate of peanut sheller is still the key problem to develop peanut sheller. According to the physical characteristics of peanut in a drum bar type peanut shelling device design. The machine can remove the peanut shell with high efficiency and good shelling effect.
At present, the shelling structure used in peanut sheller mainly consists of the steel bar or steel grid concave structure with blow and rub as its main parts, and the rubber roller or rubber floating concave plate structure mainly composed of extrusion and rubbing two major categories. The former has the disadvantage of high breaking rate of peanut, and the latter is inefficient and inefficient. There is also a differential roller roll shelling method, with low crushing rate, productivity, removal rate can achieve better results. Therefore, in this design, this principle is adopted to design peanut sheller. The cleaning mechanism is also an important part of the design. The cleaning machine uses vibrating screen and cleaning fan to achieve the purpose of cleaning, and finally clean peanuts. As part of the 1. reciprocating motor pulley 2. and a belt pulley 3. fast 4. slow fast roller roller belt pulley 5, 7. 6. and 8. speed reversing gear vibration sieve belt wheel 9. crankshaft vibration sieve 10. cleaning fan 11. vibrating screen under the action of peanut shell large was filtered, flow away from the vibration on the left side of the screen. The smaller peanut shells and peanuts are affected by the blower 10 in the process of falling. As long as the air supply is controlled, the smaller peanut shells and dust are blown away, and the clean peanuts are obtained. In addition, the design task book also requires the gap can be adjusted to adapt to different varieties of peanuts, which in the above principles can also be achieved.
