摘要
花生脱壳机可以替代手工剥壳,极大地提高花生的脱壳效率。为此,针对目前花生脱壳机存在的机器性能不稳定、适应性差、通用性差和利用率低等问题,设计了刮板式花生脱壳机,计算了脱壳机转轴部件的转速和脱壳机的功率,采用皮带传动,选用了电磁调速电动机,设计了转轴、凹板筛、料斗和箱体等零部件;通过采用电磁调速电动机和不同尺寸间隔的凹板筛提高了花生脱壳机的通用性,同时也提高了脱壳机的适应性和利用率;由于电磁调速电动机的控制器具有速度负反馈系统,可以使电动机的输出转速基本上保持不变,从而提高了脱壳机运行过程中性能的稳定性;刮板式脱壳机运行中具有冲击性,因此对转轴部件的临界转速进行了校核,结果表明,设计的转轴部件结构合理,其运行转速低于转轴部件的最小临界转速值。
The calculation results show that,the design of shaft parts reasonable structure,its operation speed below the minimum critical speed shaft parts value.designed the scraper peanut sheller,calculated the shaft parts of the sheller rotation speed and the sheller power,use the belt drive,choose the electromagnetic speed regulation motor,and design the shaft,concave board sieve,hopper,case etc,by the use of the electromagnetic speed regulation motor and different sizes of interval concave board sieve improved the generality of the scraper peanut sheller,and also improved the sheller universality and utilization rate,due to the motor controller has electromagnetic speed negative feedback system,can make the output of the motor speed basically same,can improve the stability of the sheller performance,due to scraper peanut sheller has impact in operation,so calculated the critical speed of the shaft parts,the calculation results show that,the design of the structure of the shaft parts is reasonable,its operation speed below the minimum critical speed.
