当人们需要对玉米进行脱粒时，首先人们在推动机构4中放入玉米，然后使推动机构4运转，推动机构4使玉米向前移动，同时人们使挤压机构5运转，待玉米不能再向前移动时，人们使推动机构4停止运转，进而使玉米停止移动，挤压机构5再向下推动玉米，玉米由于重力向下移动一段距离，然后挤压机构5与推动机构4配合，从而使玉米脱粒，剥落后的玉米粒和玉米芯由于重力掉落至干净的地面上，随后挤压机构5逐渐恢复原位，同时人们使推动机构4恢复原位，待玉米脱粒工作全部完成后，人们使挤压机构5停止运转，再分别收集地面上的玉米粒和玉米芯，若再次使用本设备，重复上述步骤即可。

人们在两根第一推动架44之间放入玉米，随后手动向前推动第一滑动架43，使得第一滑动架43在第一滑轨42上向前滑动，同时第一滑动架43移动带动第一推动架44向前移动，从而使玉米向前移动，待玉米不能再向前移动时，人们停止推动第一滑动架43，从而使玉米停止移动，此时玉米位于挤压环套45上方，随后挤压机构5向下推动玉米，使得玉米由于重力掉落至挤压环套45内，挤压机构5再与挤压环套45配合，从而对玉米进行挤压，同时挤压环套45将玉米粒剥落下来，剥落后的玉米粒和玉米芯由于重力从挤压环套45内掉落至干净的地面上，待挤压机构5与第一推动架44分开后，人们向后拉动第一滑动架43，从而使第一滑动架43和第一推动架44移回原位。
挤压机构5包括有第二固定架51、第一固定块52、气缸53、推动块54、电机55、转动柱56、第一弹簧57和第一滑动杆58，推动框41顶部前侧中部设有第二固定架51，第二固定架51上侧后部设有第一固定块52，第一固定块52上部设有气缸53，第二固定架51顶部设有第一滑动杆58，气缸53底部与第一滑动杆58之间连接有推动块54，推动块54与第一滑动杆58滑动式连接，第一滑动杆58上绕有第一弹簧57，第一弹簧57顶部与推动块54连接，第一弹簧57底部与第二固定架51连接，推动块54顶部安装有电机55，电机55的输出轴上设有转动柱56，转动柱56与推动块54转动式连接，转动柱56位于挤压环套45上方。
人们打开气缸53并启动电机55，气缸53运作会使推动块54在第一滑动杆58上上下反复滑动，进而使电机55上下反复移动，从而使转动柱56上下反复移动，另外电机55的输出轴转动带动转动柱56转动，当推动块54向下移动时，第一弹簧57由初始状态变为压缩状态，同时推动块54使转动柱56向下移动，转动柱56穿过第二固定架51并继续向下移动，此时玉米位于转动柱56下方，待转动柱56移至与玉米接触后，转动柱56推动玉米向下移动，同时转动柱56在两根第一推动架44之间向下移动，当玉米与第一推动架44分开后，玉米由于重力掉落至挤压环套45内，从而转动柱56对玉米进行挤压，同时挤压环套45将玉米粒剥落下来，随后气缸53使推动块54向上移回原位，第一弹簧57由压缩状态复位，弹力辅助推动块54向上移回原位，推动块54移动使电机55和转动柱56移回原位，待转动柱56从第一推动架44之间移出后，人们使第一滑动架43和第一推动架44移回原位，当玉米脱粒工作全部完成后，人们关闭气缸53，进而使推动块54停止移动，从而使电机55和转动柱56停止移动，同时人们关闭电机55，使得转动柱56停止转动。
实施例3
在实施例2的基础之上，如图1、图4、图5、图6和图7所示，还包括有往复机构6，往复机构6包括有连接块61、滚轮62、斜杆63、第二固定块64、第二弹簧65、第二滑动杆66、滑套67、第三固定块68和第三弹簧69，第一滑动架43左右两侧前部均设有连接块61，左右两侧的连接块61后侧上部内侧均转动式设有滚轮62，推动块54左右两侧后部均设有滑套67，左右两侧的滑套67内侧均滑动式设有第二滑动杆66，左右两侧的第二滑动杆66底部均设有第二固定块64，左右两侧的第二滑动杆66上均绕有第二弹簧65，第二弹簧65顶部与滑套67连接，第二弹簧65底部与第二固定块64连接，左右两侧的第二固定块64底部均设有斜杆63，斜杆63与滚轮62配合，推动框41顶侧后部左右两侧均设有第三固定块68，左右两侧的第三固定块68与第一滑动架43之间均连接有第三弹簧69。
当推动块54向下移动时，推动块54会在第二滑动杆66上向下滑动，第二弹簧65由初始状态变为压缩状态，第二弹簧65带动第二固定块64向下移动，从而使斜杆63和第二滑动杆66向下移动，由于滚轮62与斜杆63配合，斜杆63移动使滚轮62向前移动，同时斜杆63与滚轮62接触并产生摩擦，摩擦力使滚轮62转动，另外滚轮62移动并推动连接块61向前移动，进而使第一滑动架43向前移动，从而使玉米和第一推动架44向前移动，如此达到了自动送料的效果，同时第三弹簧69由初始状态变为拉伸状 态，当斜杆63不再向下移动时，滚轮62停止转动，随后推动块54向上移回原位，第二弹簧65由压缩状态复位，从而使斜杆63和第二固定块64移回原位，此时第三弹簧69由拉伸状态复位，从而使第一滑动架43和第一推动架44移回原位，从而使连接块61和滚轮62移回原位。
还包括有筛选机构7，筛选机构7包括有第四固定块71、第三滑动杆72、第四弹簧73和筛框74，推动框41前侧下部设有第四固定块71，第四固定块71底部与推动框41底部均设有两根第三滑动杆72，四根第三滑动杆72之间滑动式连接有筛框74，筛框74位于挤压环套45下方，四根第三滑动杆72上均绕有第四弹簧73，第四弹簧73底部与筛框74连接，后侧的两根第四弹簧73顶部与推动框41连接，前侧的两根第四弹簧73顶部与第四固定块71连接，筛框74内部开有二十个筛孔75。
剥落后的玉米粒和玉米芯由于重力从挤压环套45内掉落至筛框74内，部分玉米粒通过筛孔75掉落至地面上，同时人们手动使筛框74在第三滑动杆72上上下反复滑动，此时第四弹簧73发生弹性形变，从而使筛框74内的玉米粒和玉米芯震动，使得筛框74内更多的玉米粒通过筛孔75掉落至地面上，此时玉米粒不再阻挡玉米芯，玉米芯由于重力再从筛框74内滚落至地面上，如此达到自动筛选的作用。
还包括有自动下料机构8，自动下料机构8包括有支撑架81、第二固定板82、挡板83和下料框84，底座1上后部设有支撑架81，支撑架81顶部设有第二固定板82，第二固定板82与第二固定架51之间连接有下料框84，下料框84与第一滑动架43滑动式连接，第一滑动架43后侧上部设有挡板83。
人们在下料框84内放入一些需进行脱粒的玉米，并使玉米保持竖直状态，随后玉米由于重力向前移动，然后最前侧的玉米由于重力从下料框84内掉落至两根第一推动架44之间，当第一滑动架43向前移动时，第一滑动架43移动使挡板83和最下侧的玉米向前移动，此时挡板83能够阻止下料框84内剩余的玉米向下移动，当第一滑动架43向后移回原位时，第一滑动架43使挡板83移回原位，此时下料框84内剩余的玉米由于重力向下移动，最前侧的玉米掉落至两根第一推动架44之间，如此达到了自动均匀下料的效果。
还包括有碰撞机构9，碰撞机构9包括有推动杆91、凸块92、连杆93和第五固定块94，左侧的连接块61底部设有推动杆91，筛框74左侧设有第五固定块94，第五固定块94顶部设有连杆93，连杆93顶部设有四个凸块92，凸块92与推动杆91配合。
当左侧的连接块61向前移动时，左侧的连接块61带动推动杆91向前移动，待推动杆91移至与凸块92的凸起部分接触后，推动杆91移动使凸块92向下移动，继而使连杆93向下移动，从而使第五固定块94向下移动，第五固定块94移动使筛框74向下移动，第四弹簧73由初始状态变为拉伸状态，随后推动杆91与凸块92的凸起部分逐渐分开，第四弹簧73仍处于拉伸状态，弹力使筛框74和凸块92向上移动，如此推动杆91移动会使筛框74上下反复移动，筛框74移动使玉米粒和玉米芯分离，从而达到了自动筛选的目的，待推动杆91向后移回原位后，第四弹簧73由拉伸状态复位，弹力使筛框74和凸块92移回原位。
