Because the sample difference, need so " amount " that homogeneous handles in other words sample shared volume in sealed plastic bag be different.The sealed plastic bag that sample is housed is suspended to actuating doors and bounces between the plate, so actuating doors and to bounce distance between the plate be to look the volumetric quantity of sample in the sealing bag and adjust.Designed for this reason structure is (as Fig. 1): speed reduction unit is fixed on the U type supporting plate, and U type supporting plate and two back shaft welding are fixing.The two ends of two back shafts are installed on the positioning round orifice of support and the positioning round orifice of Instrument shell medial branch fagging respectively.The top of two back shafts is fixed by web joint with screw, making two back shafts is one.Leading screw and adjusting runner are fixed as one, the web joint center pit is used for the location of leading screw, leading screw rotates in the silk braid hole at back up pad center and just can make the displacement of speed reduction unit before and after producing so, realizes actuating doors thus and bounces distance between the plate and adjust (direct current generator fixedly connected with speed reduction unit after direct current generator be unsettled).For clearly demonstrating this structure, Fig. 3 amplifies the part of Fig. 1 from depression angle.
Before address, sample sack is to place the actuating doors top and seal with actuating doors, with the correspondence position that locking hinge inboard is provided with magnetic sheet Hall switch is housed on the midfeather top of sample operation chamber, so when with the locking hinge actuating doors being closed, bounce plate and get final product work by handle for this reason.Otherwise, when actuating doors is opened, bounce plate and can stop action.When the sample size of Chu Liing was very little if desired, bouncing the effective range that plate bounces may be not ideal.The key that addresses this problem also can be dwindled the spacing of bouncing between the plate and lifting and bounce height except being reduced to bounce the distance between plate and the actuating doors, and can bounce the plate inside front at original two and respectively install a trace additional and bounce plate (as Fig. 4) this moment.The mutual spacing that bounces plate is reduced and hoisting depth.
