Series connection of a multi-layer transfer layer test and the multiple drop tests is adopted, during the multiple drop tests, chips are screened out, and the participating samples are thrown into the next test, and the requirement for the multiple drop tests of the samples easy to break is met.
Description
Technical field
The present invention relates to a kind of fall-down test pick-up unit, particularly a kind of multistage drop machine.
Background technology
A lot of products, before production definition, need to carry out anti-collision performance detection, as mobile phone, draw-bar box etc., generally adopt drop machine to detect.For easy broken samples such as biomass granule fuels, need equally detection of biological matter fuel particle anti-collision performance, verify the particle integrity degree of biomass granule fuel under shock condition, improve the quality of products.Traditional vertical drop machine is traditionally arranged to be the platform of lifting of certain altitude, below is for falling floor, product falls and falls floor and simulate impact from lifting platform moment, in the time of needs test of many times, need manually product to be reapposed and lifts platform, or adopt lifting apparatus again product to be promoted.For biomass granule fuel, particle own is less, and may cause fragmentation after once falling, and particle is irregular, is difficult to adopt lifting apparatus to reset, and can only pass through manual reset.And cause the sample at broken end for easy fragmentation, because each fall-down test can produce broken end, the drop machine that multiple-layer stacked can not be set is simply tested.
And the fall-down test of biomass granule fuel is also different with other product evaluation standards, the products such as mobile phone, draw-bar box, after fall-down test, are generally evaluated by the detection of outward appearance, main performance.And the fall-down test of biomass granule fuel is generally evaluated by the weight of impacting rear, large build particle, the particle that is less than former particle certain percentage volume will be rejected.
Patent Office of the People's Republic of China's on September 25th, 2013 disclosed CN 103323205A patent application document, name is called a kind of steel ball fall-down test device, this device rises to steel ball by the screw elevator being obliquely installed the top of whereabouts straight tube, and the bottom of whereabouts straight tube connects the bottom of screw elevator by raceway.Although this device is also for granular steel ball fall-down test, not high and more hold breakable biomass granule fuel for roundness, biomass granule fuel cannot in raceway, roll smoothly and broken granule is easy to stop up raceway.
Summary of the invention
The repeatedly fall-down test problem that the object of the invention is to solve existing drop machine and cannot meet easy broken sample, provides a kind of multistage drop machine.
The technical solution adopted for the present invention to solve the technical problems is: a kind of multistage drop machine, comprise support, frame bottom is provided with falls floor, support top is provided with the platform of lifting that can folding, describedly lift platform and fall the conversion layer that is provided with some layers between base plate, described conversion layer comprises that accepting upper strata falls sample, and the bearing plate that can open downwards, bearing plate below is provided with can open the plate of lifting of throwing in sample downwards, bearing plate and lift the screen cloth that is provided with inclination between plate, screen cloth has broken last feeder, screen cloth lowest part is provided with and is communicated with the opening of lifting plate top.This device can carry out fragile samples continuously, as the repeatedly fall-down test of biomass granule fuel, the bearing plate that conversion layer is gone up most withstands shocks as the floor of falling of previous test, after previous test completes, there is broken larger particles and the broken end producing of sample bearing plate top; Bearing plate open by impact after sample send into below inclined screen online, the granule that volume is less than raw sample certain percentage by screen cloth screens out, collect and shift by broken last feeder, bulky grain remnants fall into and lift on plate as the sample of rear test, lift to do to open sample is rendered to next conversion layer, repeat said process, until sample falls floor through falling after how many tests.This device can be at fragile samples repeatedly in fall-down test, realizes robotization and screens out and collect broken end, and will participate in sample and continue to drop into and test next time.
As preferably, described in lift platform and formed by symmetrical two boards body, lift the middle part of platform and can open downwards.
As preferably, described bearing plate is made up of symmetrical two boards body, and the drive-connecting shaft of left and right two plate bodys is positioned at the middle part of plate body, and the inner side that under open mode, two plate bodys are relative is upturned, and under two laterals, opens.
As preferably, described screen cloth is being obliquely installed that both sides are high, middle part is low, screen cloth middle part lowest part opening.Broken sample falls from screen cloth both sides, and bulky grain tumbles middle part and falls into lifting on plate of below, and granule screens out as broken end.
As preferably, described in lift plate and formed by symmetrical two boards body, lift the middle part of plate and can open downwards.
As preferably, described in lift platform, fall floor, the both sides of conversion layer are provided with the side shield that prevents that sample from dropping from the side.
As preferably, described in lift platform, bearing plate, the both sides of lifting plate are equipped with the block that prevents reverse opening.
As preferably, described broken last feeder is obliquely installed, and the outlet at bottom place of the broken last feeder of each conversion layer is collected to same broken last box, and broken last box bottom is provided with weighing device.Broken last general assembly (TW) in monitoring test process in real time, assessment percentage of damage.
As preferably, described in lift platform one side and be provided with samples weighing device.
As preferably, described in lift platform, fall floor, conversion layer folding all adopts Electric Machine Control.
The present invention adopts multilayer conversion layer to test repeatedly the series connection of fall-down test, screens out broken end between test of many times, and will participate in test next time of sample input, meets the repeatedly demand of continuous fall-down test of fragile samples.
