Embodiment
Below in conjunction with drawings and Examples, the utility model is described further.Although the utility model will be described in conjunction with preferred embodiment, should know, not represent the utility model restriction in the described embodiment.On the contrary, the utility model will contain can be included in attached claims limit scope of the present utility model in alternative, modified and equivalent.
As shown in Figure 1, the acceleration detecting of bed of material impact ball mainly comprises: base 1, anvil 2, coaming plate 3, guide pipe 4, the impact ball 5 of band guide pillar, acceleration transducer 6, locking plate 7, computer 8, data line 9, angle sheave 10, reel 11, rotating shaft 12, increase line 13, cramping body 14, clamping screw 15, trip bolt 16, support 17.It is characterized in that: when impacting the bed of material below pellet impact, obtained by high precision acceleration transducer and impact the acceleration over time data of ball in impact process, and these data and temporal information are saved on computer, utilize acceleration change data acquisition medium ball impulsive force changing value, in conjunction with the broken situation of bed of material particle, analyze initial thickness of feed layer, height of the fall ball to the impact of Particle Breakage, to obtain optimal impact energy.
This device adopts the impact ball 5 of band guide pillar to impact the below bed of material along guide pipe 4 at vertical direction, and the acceleration transducer 6 be installed on directly over medium ball detects the acceleration of vertical direction in impact process.Guide pipe is vertically placed, and has small―gap suture between the guide pillar of impact ball, while the free-falling of guarantee medium ball, ensure that impact process medium ball does not rotate and deflection.For the ease of observe, guide pipe adopt transparent material, length is greater than height of the fall ball, during installation the height outline of bottom higher than the bed of material in case the air-flow that falling stop ball causes dispel below the bed of material.The guide pillar impacting ball requires it is hollow, reserves the space of installing acceleration transducer, and adopts light material, reduce the impact of guide pillar quality impact energy, and guide pillar height is not easily too large, about medium ball diameter about 1.5 times.Need to grind the installation that a facet is convenient to acceleration transducer with on sphere directly in the impact of guide pillar.
The rotating shaft 12 being installed on support 17 drives reel 11 to rotate, and the impact ball 5 of band guide pillar is risen to certain altitude by increase line 13.The installation site of rotating shaft and angle sheave must make the center superposition of increase line and guide pipe, reduces the impact impacting increase line when ball falls.The rotation of rotating shaft must be flexible, to reduce the impact of the batting free-falling that liquidates.
This device, by acceleration transducer 6, to be connected with computer 8 by data line 9 and to realize acceleration information collection, and adopt locking plate 7 by data line and increase line consolidation, avoid data line to contact with guide pipe by angle sheave 10.Very short owing to impacting the bed of material time, the response frequency of acceleration transducer will enough high (more than 1MHz), and the acquisition speed of computer is enough fast simultaneously.When locking plate is by data line and increase line consolidation, ensure that data line is in loose condition (of surface) slightly, prevent from impacting stretching data line when ball falls and cause data transmission failure.
This device guiding pipe 4 is clamped with clamping screw 15 by upper and lower two cramping bodies 14, and cramping body is installed on support 19 by trip bolt 16.The Clamping Center of upper and lower two cramping bodies must keep vertical, to ensure that guide pipe is in vertical state after being clamped.
This device is impacted the bed of material and is placed in above anvil 2, and periphery coaming plate 3 fences up.For ease of observation, coaming plate adopts transparent material.For reducing coaming plate to the restriction of impacting the part bed of material, the diameter of coaming plate horizontal extent must be greater than more than 3 times that impact bulb diameter, to ensure that being impacted partial material is in unrestricted state.
During use, first according to shock height, the length of impacting the guide pillar size determination guide pipe 4 of ball 5 and internal diameter size, guide pipe 4 is placed on cramping body 14.The certain thickness bed of material is spread in coaming plate 3 above anvil 2.Degree of will speed up sensor 6 is installed to the facet center above the impact ball 5 of band guide pillar, then is placed in guide pipe 4 by impact ball 5, and regulates the position impacting ball 5 to make it the height and position being in setting with rotating shaft 12.Open the data acquisition software of computer, start to gather the acceleration information impacting ball, release rotating shaft 12, allow the free-falling of impact ball 5 impact the below bed of material, the acceleration change information of the whole impact process of computer record, for subsequent analysis.After impacting, rotating shaft 12 promotes and impacts ball 5, the broken state of the Observable bed of material.
