3) it is crushed mechanism return；

After Collapse of Concrete, quick movement mechanism and servo motion system start simultaneously, and conquassation mechanism is driven quickly to return To initial position；When pressure head 21 rises to rotation 20 top of material toggling arm, starting material toggling motor 17 drives rotation material toggling arm 20 to revolve Turn, the capaciting material groove rotated on material toggling arm 20 is gone into rejected material position III and is stopped, the particle sample 12 after conquassation is automatically under rejected material mouth It falls in waste bin 16, passes through 15 periodic cleaning of waste material box；

4) after the above process, the conquassation experimentation of a material particles 12 all terminates, and repeats step 1)-step 4) it, can be tested next time.

It the feed appliance, baiting control device 10, material toggling motor 17, pressure sensor 25, quick motion motor 38 and watches It takes motor 37 and is separately connected control system, step 1)-step 3) process is carried out automatically controlling by control system.

In the utility model, vibrating disk in the feed appliance is commercially available finished product, can by particle sample 12 one by one from Material outlet on feed bin 11 is sent out, and controls the particle sample sent out every time through feeder pipe 9 by photoelectric counter or optoelectronic switch 12 be one, and the volume of feed bin 11 is determined according to the experimental measuring of 12 every batch of of particle sample.

As shown in Fig. 2, being fallen after feeder pipe 9 from discharge port by the particle sample 12 that feed appliance is sent out, fall directly into Into the capaciting material groove rotated on material toggling arm 20, i.e., splicing position I, rotation 20 splicing of material toggling arm are (square as shown in the figure clockwise after the completion To) certain angle is rotated horizontally, stop after so that capaciting material groove is reached conquassation position II, is moved down as pressure head 21 and by pressurization as defined in standard Speed is completed the conquassation to granule materials 12 and is operated；After the completion of Collapse of Concrete, rotation material toggling arm 20 continues to horizontally rotate clockwise Certain angle reach rejected material position III, by the particle sample 12 being crushed give up as hopeless material mouth be sent into waste bin 16 in, waste bin 16 leads to The bottom surface of waste material box 15 is inclined-plane, and waste from stacking, will after the completion of the conquassation experiment of one or several batches in waste material box 15 Waste material box 15 is removed from workbench, that is, is convenient to carry out toppling over processing to waste material.

Supporting element of the middle supporting plate 22 being crushed in mechanism as the connector and stress for being crushed mechanism and workbench, middle support Plate 22 is supported by 4 root posts 8.When worm screw 35 rotates under the drive of servo motor 37, worm gear 31 drives lifting nut 27 to rotate, And elevating screw 28 is made to generate vertical displacement movement, sliding sleeve 24 is connect by connector 26 with elevating screw 28, pressure sensor 25 are fixed in sliding sleeve 24, and when elevating screw 28 is gone up and down, sliding sleeve 24 is moved along guide sleeve 23.Pressure head 21 slideably with sliding sleeve 24 connections reserve a distance between 21 top of pressure head and the bottom surface of pressure sensor 25, when pressure head 21 touches particle sample When 12, pressure head 21 first generates micro sliding upwards and then contacts with pressure sensor 25, to guarantee the standard for being crushed the time started Pressure signal real-time transmission is scaled actual pressure value to control system by pressure sensor 25 after conquassation starts by true property.

It is to shake the output smoothing acrotism of crushing force that the main purpose of servo motor 37 is used in servo movement mechanism, Performance in this respect is better than stepper motor.It is converted in addition, servo motor 37 can be realized to after worm and gear, the transmission of screw rod screw Vertical displacement amount accurately controlled because servo motor 37 receive control pulse when, displacement and control umber of pulse It measures corresponding, thus can calculate displacement by sending out how many a pulsed quantities, can be subsequent calculating particle sample 12 Diameter highly reliable, high-precision measurement means are provided；In the utility model, the driving speed of servo motor 37 is set as two Kind mode, first is that fast feed, second is that conquassation feeding.The desin speed of fast feed is 10mm/s, its speed when being crushed feeding Degree will be run by speed as defined in concerned countries standard, standard speed are as follows: 15mm/min (0.25mm/s).

In quick movement mechanism, when the starting of quick motion motor 38, output power passes through driving wheel 39, synchronous belt 2 It is transmitted to synchronizing wheel 3, drives servo-actuated screw rod 5 to generate rotation by synchronizing wheel 3, it is engaged therewith servo-actuated when the rotation of servo-actuated screw rod 5 Screw 6 then generates vertical displacement, so that dynamic supporting plate 29 and all components thereon be driven integrally to do vertical lifting movement；Quickly fortune The dynamic preferred stepper motor of motor 38 is advanced because it can receive control instruction by pulse control quantity；It should in the utility model Motor is defined as quick motion motor, refers to that it is used to generate the displacement of fast speed, and design object presses 20mm/s, it can be Conquassation mechanism is set to be moved to designated position in the shorter time.
