拨动棘爪156通过设置在其上侧的滑块在棘爪滑槽157内滑动，滑块通过棘爪连杆158与蜗轮159连接；蜗轮159啮合蜗杆160；因为蜗轮蜗杆配合可以产生较大的力量，所以此处使用该结构作为拨动蓄力架151的联动机构。
蜗轮159、蜗杆160的中轴均固定在弹射轨道12的侧壁上；蜗轮159一侧设置偏心轴杆，棘爪连杆158一端与该偏心轴杆连接，另一端与拨动棘爪156上侧的滑块转动连接；
蜗杆160的外侧设置从动轮161，传送机构2的传送带转辊带动主动轮162，从动轮161与主动轮162之间通过连杆163连接；从动轮161蜗杆160同轴，二者通过单向轴承连接。
主动轮162与传送带的其中一个转辊同轴，或者通过齿轮机构联动。
蓄力架151上表面设置可伸缩的拉杆，拉杆顶端设置在弹射轨道12底部的滑道164内，蓄力架151的上表面与拉杆的上端之间设置弹簧165。
拉杆与弹簧165分别沿两根侧杆1512各设置两根。
当承托板133上无沙袋时，弹簧165及拉杆收缩，侧杆1513的棘齿条与固定棘爪155、拨动棘爪156接触；当承托板133上落下沙袋时，弹簧165及拉杆伸长，侧杆1513的棘齿条与固定棘爪155、拨动棘爪156脱离。
弹射轨道12后侧下部设置挡板166，挡板166朝向中部杆1511一侧设置压簧167。
固定棘爪155位于弹射轨道12的前端部，蓄力架151侧杆1512上棘齿条的长度为，当蓄力架151移动到贴近压簧167时，其棘齿条前端部的棘齿与固定棘爪155分离且其距离大于等于压簧167的压缩距离，当蓄力架151移动到靠近压簧167时，在压簧167的作用下会小距离的将其向弹射轨道12出射面的方向推动，即小距离的复位，可以避免当拨动棘爪156将蓄力架151拨动至弹 射轨道12后部时，而还没有沙袋落下触发弹射动作，此时会因为蓄力架151无法继续运动而导致整个机构卡主的情况发生。
弹簧支杆一152设置两根，分别设置在中间块132下部相对的两侧；与弹簧支杆一152对应，弹簧支杆二153、拉簧154也对应设置两根。
蓄力架151的两个侧杆1512的下侧面设置有若干滚轮1513。
弹射轨道12的侧壁内侧面竖直设置有转辊121。
两个侧杆1512的外侧面均设置有棘齿条，与其对应的联动机构均设置两组。
弹射机构1与传送机构2之间通过大连杆及液压杆连接，大连杆与弹射机构1的侧壁转动连接，液压杆连接传送机构2的两侧及弹射机构1的上表面。
传送机构2包括一级传送带21和二级传送带22二者通过支架连接。二级传送带22和一级传送带21贴合的一端为进料端，另一端朝向弹射机构1为出料端，弹射机构1位于二级传送带22出料端的的前下侧，二级传送带22的出料端设置倾斜板23。倾斜板23用于辅助二级传送带22出料端送出的沙袋落入弹射轨道12上的承托板133上。
二级传送带22上设置传感器24，当传感器感应到二级传送带22上有沙袋时，则一级传送带21停止转动。通过对联动机构各个部件具体尺寸的调整，满足当二级传送带22进行传送时，其上的沙袋由其进口行至出料口的过程中，弹射机构1的蓄力架151及弹射板132等机构复位至拉簧154的最大拉伸状态。即处于蓄力待发的状态。通过传感器控制传送带分时段间隔输送物品为现有技术，在此不再赘述。
本装置工作时，调整好弹射机构1和传送机构2的位置，将沙袋逐一放在一级传送带21上，经一级传送带21传送至二级传送带22，然后进入弹射机构1，由弹射机构1将沙袋弹射出去。
在二级传送带22转动的过程中，由其传送带的转辊带动主动轮162转动，通过从动轮161将动力传递给蜗杆160，经由蜗轮159通过棘爪连杆158带动拨动棘爪156拨动蓄力架151两侧的棘齿条，从而使拉簧154拉伸蓄力。
当沙袋由传送机构2落入弹射机构1中时，因为沙袋落至承托板133上，所以对承托板133施加压力，使蓄力架151也向下运动，从而其棘齿条与固定棘爪155和拨动棘爪156分离，拉簧154复位，在拉簧154的作用下弹射板132推动沙袋从弹射机构1的出射口射出。
当承托板133上没有沙袋后，弹簧165带动蓄力架151向上移动，此时固定棘爪155和拨动棘爪156再次与棘齿条相抵。
以上所述仅为本发明的较佳实施例，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本发明的保护范围之内。
