State anyhow can be kept by setting the conveyer mechanism 3 at 4;As shown in figure 43, conveyer mechanism 3 at this time will move to
At latch mechanism 8;Upper locking piece 37 at mechanism for locking up 8 will be engaged with the L shape protective plate 33 being mounted on the second link block,
L shape protective plate 33 will wrap the oneth L shape sports bars 65 of the first L shape sports bars 65 simultaneously, so conveyer belt machine at this time
Structure 3 will move under driving device 2, but upper locking piece 37 at this time will will limit the movement of L shape protective plate 33, so at this time
Third connecting plate 52 and the first connecting plate 44 will the restoring force of scroll spring 59 effect under and driving device 2 common work
With lower movement, so the mounting blocks 43 being mounted on the first connecting plate 44 at this time drive the buckle 47 being mounted on mounting blocks to transport
Dynamic, as shown in Figure 26,27, buckle 47 at this time will push the first limited block 53 and the second limit under the action of pushing inclined-plane 55
Position block 56 moves, the first limited block 53 and the second limited block 56 at this time will relative motion so that buckling 47 can weigh
It is newly moved into the first limited block 53 and the limiting slot 54 of the second limited block 56 formation, so that the first limited block 53 and the
Two limited blocks 56 can limit the movement of buckle 47, so that the first connecting plate 44 can be reconnected with the second connecting plate 50
Together, since the coefficient of elasticity of third spring 58 is less than the coefficient of elasticity of second spring 35;As shown in Figure 21,22,23, hereafter
38 direction of guide groove of being opened on the locking inclined-plane 40 that will push on upper locking piece 37 along the second fixed block 34 of L shape protective plate 33 transport
It is dynamic, so that L shape protective plate 33 can be smoothly across upper locking piece 37;Into hold-down mechanism 73 meeting of conveyer mechanism so that
Conveyer mechanism 3, which enters, to be pulled 78 at conveyer belt;Into mechanism for locking up 8 conveyer mechanism 3 will make conveyer mechanism 3 into
Enter 79 at conveyer belt locking, conveyer mechanism 3 hereafter will make conveyer mechanism 3 enter 80 at conveyer belt cleaning, be convenient for
Staff can sweep the sundries on conveyer mechanism 3, and the transport inspection of a cargo is completed to this present device.
