连接绳12的一端与第三卡接块231侧面中心固定连接，连接绳12滑动搭接在限位滚轴215的外表面，调节握把163通过第一卡接块165与定位框162的一端外表面活动卡接，第一卡接块165和定位框162的一端外表面均呈楔形设置，且所述定位框162一端的楔形分为三组设置。

通过上述技术方案，能够使得封堵块235的一端通过输送槽222与限位转轴223的中部外表面滑动卡接，从而能够对输送槽222起到活动封堵作用，而且封堵块235的另一端通过限位滑槽225与限位转轴223的一端外表面滑动卡接，从而能够对封堵块235的滑动起到限位作用，其中第三牵引绳236的数量为四，而第二牵引绳234的数量为八，以及第一牵引绳233和封堵块235的数量均为十六，从而能够根据需要对种子输送部22外表面的封堵块235进行滑动控制，同时能够对种子播种间距进行调节。
通过在播种机构2的侧面设置调节部23，能够对封堵块235的滑动起到控制作用，而且第一牵引绳233、第二牵引绳234和第三牵引绳236均通过限位扣232与连接绳12一端的第三卡接块231转动连接，从而在种子输送部22转动时，不会使得第一牵引绳233、第二牵引绳234和第三牵引绳236之间缠绕，而且连接绳12对封堵块235进行控制时，限位滚轴215会对连接绳12的滑动起到限位作用，从而保证连接绳12对第三牵引绳236进行正常的牵引。
本发明的工作原理：在对种子进行播种时，先将种子播种机的限位框架11安装在农机的尾端，同时将传动杆16的一端与农机的固定连接，然后将种子放置到种子供料斗212的内部，再启动农机带动连接机构1和播种机构2同步移动，与此同时农机会带动传动杆16同步转动，而传动杆16转动时，会通过锥形齿轮15带动传动轴14同步转动，其中传动轴14转动时，会通过外表面的第一传动链轮13和传动链条带动限位转轴223同步转动，在限位转轴223转动时，会通过输送槽222带动种子供料斗212内部下落的种子同步转动，直至将种子带动到种子导架217的顶端，同时种子会沿着种子导架217下落到犁头218翻土后的沟槽内部，随着播种机构2的移动，种子导架217两侧后方的覆土轮216会对沟槽两侧的图进行碾压，从而对播种的种子进行覆盖，从而完成对种子的连续播种，其中在使用种子播种机对不同种子进行播种时，就需要根据种子的生长条件对播种机构2进行调节，在需要扩大种子播种间距时，就可以对第三牵引绳236连接的封堵块235进行控制，在需要缩小种子播种间距时，就可以对第一牵引绳233连接的封堵块235进行控制，其中在对封堵块235进行控 制时，就可以拉动调节握把163带动连接绳12进行滑动，直至调节握把163外表面的第一卡接块165转动挤压定位框162横向滑动，在定位框162一端与第一卡接块165分离时，涨紧弹簧161会牵引定位框162复位滑动，同时卸去调节握把163的外力，定位框162的端部会对第一卡接块165起到阻挡作用，从而使得调节握把163牵引连接绳12后的位置保持不变，其中在对不同尺寸的种子进行播种时，可以通过拉动调节握把163偏转的幅度，能够使得调节握把163外表面的第一卡接块165与定位框162一端三组楔形端对应卡接，所以在调节握把163带动第一卡接块165偏转的幅度越大，就可以增加封堵块235的位移距离，同时封堵块235会带动一端的筛板在输送槽222内部滑动到相应的位置即可，而连接绳12滑动时，会通过一端连接的第一牵引绳233或第二牵引绳234或第三牵引绳236同步滑动，而第一牵引绳233或第二牵引绳234或第三牵引绳236在滑动时会牵引封堵块235同步滑动，从而使得封堵块235的一端与输送槽222分离，而且在封堵块235滑动时会带动一端的筛板237同步滑动，从而使得筛板237移动到输送槽222的内部中心，从而能够对下落的种子进行筛选，与此同时封堵块235的另一端会在限位滑槽225的内部滑动，并且封堵块235的一端面会挤压复位弹簧226进行收缩，在对封堵块235的位置完成调节后，就会使得对应的输送槽222对种子供料斗212内部，下落经过筛板筛选的大小均匀合格优良的种子进行承接，然后随着种子输送部22的转动，就会使得输送槽222对内部的种子进行运输，直至通过种子导架217排放到田地内部即可，从而完成种子的播种，其中种子输送部22在转动时，会通过第一牵引绳233、第二牵引绳234和第三牵引绳236带动 限位扣232在连接绳12的一端进行转动，从而避免第一牵引绳233、第二牵引绳234和第三牵引绳236之间相互缠绕，所以在速度不变的前提下，控制封堵块235与输送槽222分离的数量越多，就会缩小对种子播种的间距，控制封堵块235与输送槽222分离的数量越多少，就会扩大对种子播种的间距，而且通过对播种机的调节，能够避免购买多个不同的播种机，从而降低费用的支出，而且能够避免播种机过度占用空间，在对种子垄间距进行调节时，就可以对连接机构内部的播种机构进行拆卸，然后调节播种机构之间的位置，然后再对播种机构进行固定即可，所以通过对播种机构2的调节控制，就可以使得种子播种机针对不同种子进行不同间距的播种。
以上对本发明的一个实施例进行了详细说明，但内容仅为本发明的较佳实施例，不能被认为用于限定本发明的实施范围。凡依本发明申请范围所作的均等变化与改进等，均应仍归属于本发明的专利涵盖范围之内。
