Description

三次上料机草料压持机构 技术领域
本实用新型属于机械技术领域，涉及一种三次上料机，特别是一种三次上料机草料压持机构。
 背景技术
目前，很多菌类完全依靠培养基中的营养物质进行生长发育。现有的菌用培养基一般由草料和辅料组成，辅料一般采用鸡粪、石膏、土料等所形成的混合物。
目前培养基加工一般采用机械化设备加工，该机械化设备一般包括输送带和依次设置在输送带上的草料进料机构、草料压持机构和覆土输送机构。使用时，草料由草料进料机构送入草料压持机构，草料经草料压持机构向下压实后在输送带作用下往前输送至覆土输送机构，接着覆土输送机构往草料上倒入土料，以在草料上平铺一层土料层。
上述设备存在一个问题：当覆土输送机构上没有土料时，其会停止输送带运行直到检测到有土料，当输送带停止运行时，草料会一直被压在草料压持机构下方，导致草料顶部出现坑洞，影响后续土料平铺，从而影响培养基质量。
 技术问题
本实用新型的目的是针对现有的技术存在上述问题，提出了一种可提高土料铺设质量的三次上料机草料压持机构。
 技术解决方案

实际产品中，三次上料机还包括用于输入土料的覆土输送机构，且草料压持机构和覆土输送机构沿输送带输送方向依次分布。
使用时，草料经输送带运输至压辊下方，利用高低配置且同步转动的多根压辊，向下压实草料，接着覆土输送机构往压实草料上方逐步倒入土料，实现覆土操作。当覆土输送机构上无土料时，驱动件带动支架向上摆动使压辊上移脱离草料，防止压辊长期压在草料上，有效避免草料顶部下陷形成凹坑，确保土料较好平铺在草料上，以提高铺设质量，从而提高培养基加工质量。
在上述的三次上料机草料压持机构中，上述的支架包括沿输送带宽度方向并列设置的两挡板，且压辊两端分别转动支撑在两挡板上；两挡板一端均通过上述转轴与机架铰接，驱动件有两个且分别与两挡板另一端连接。采用上述设计，具有结构简单、组装方便的优点。
在上述的三次上料机草料压持机构中，两挡板之间设有横梁，横梁长度沿输送带宽度方向延伸，且横梁两端分别与两挡板固连。横梁将两挡板连接起来，确保两挡板同步运行，提高工作稳定性。
在上述的三次上料机草料压持机构中，机架上成型有形状和尺寸均与挡板匹配的两插槽，且两挡板未与驱动件连接的一端分别插接在两插槽内，两转轴分别固设在两插槽内，挡板上贯穿设有供对应转轴穿过的圆孔。
在上述的三次上料机草料压持机构中，转轴两端均伸出插槽，转轴一端具有环形凸头，转轴另一端固设有限位件，且环形凸头和限位件均紧压在插槽外壁上，以形成较大摩擦来限位转轴，具有结构简单、安装方便的优点。
在上述的三次上料机草料压持机构中，转轴上具有沿转轴径向贯穿设置的通孔，限位件为卡设在通孔内的限位柱，限位柱两端均伸出通孔并紧压在插槽外壁上。
作为另一种方案，在上述的三次上料机草料压持机构中，限位件为螺接在转轴上的螺帽，且螺帽端面紧压在插槽外壁上。
在上述的三次上料机草料压持机构中，驱动件为气缸或油缸，驱动件包括缸体和活塞杆，缸体和活塞杆均通过水平设置的轴体分别与机架和挡板连接，且轴体和转轴平行设置。
作为另一种方案，在上述的三次上料机草料压持机构中，驱动件为电动推杆，且电动推杆的主轴与挡板固连。
在上述的三次上料机草料压持机构中，压辊两端分别穿过两挡板，旋转机构包括固定在横梁上的电机，电机通过传动结构驱动所有压辊同步转动。
在上述的三次上料机草料压持机构中，传动结构包括固定在转轴一端的从动链轮，且所有从动链轮均处于同一侧，电机主轴上固定有主动链轮，且主动链轮和从动链轮通过链条连接。
