Specific embodiment
Referring to the drawings embodiment is described further.
Referring to figs. 1 to Fig. 3, pavement strength instrument, predominantly top are by symmetrically arranged pole 110 and the casing of bottom
111 compositions, are cavity 113 in casing 111, the holding tray 215 being provided with cavity 113 on screw mandrel 114 and screw mandrel 114, screw mandrel
114 openings 117 that can be arranged by 111 upper table surface of casing 112 are risen to outside cavity 113, and article to be detected is placed on
Put on disk 215, during screw mandrel 114 rises, 112 periphery of table top is provided with opening 117, in the cavity 113 under table top 112
Lifting and baffle plate 119 is provided with, and 215 slow rising of holding tray is caused by starting screw mandrel 114, until article to be measured and pole
The proving ring 216 arranged on 110 continues to treat survey article after contacting carry out applying pressure detecting, due to transparence baffle plate 119
Table top 112 surrounding is closed in the presence of lifters 118, it is to avoid after screw mandrel 114 clamps article to be measured with proving ring 216,
Article to be measured is caused to drop powder and particles splatter to table top after reaching pressure limit to article to be measured during pressurizeing
On ground outside 112；The material design of baffle plate 119 intuitively observes article to be measured for the transparence people that conveniently can work
Pressurized situation, it is to avoid the stop of sight line.
With reference to Fig. 4, line slip connection between symmetrically arranged pole 110 and proving ring 216, can be entered on table top 112,
When proving ring 216 needs, when the 110 enterprising line slip of pole of 216 both sides of proving ring is located at, sliding part 217 can be caused to prop up
Enter line slip in slide rail 218 on bar 110；When needing to carry out pressure test to soil block it is required that proving ring 216 is solid
It is scheduled on 110 component of pole, being therefore provided with multiple through holes on the slide rail 218 of pole 110 can be with 216 both sides of proving ring
Jack overlaps, and the jack after coincidence can be coordinated with inserted link 219 with through hole so that proving ring 216 is fixed on holding on pole 110
Motionless.
With reference to Fig. 5, the opening dropped in recovery room 116 for powder is provided with the lower section table top 112 of holding tray 215
117, rotating shaft 212 is provided with opening 117 and rotates the portable plate 210 being connected with 117 inwall of opening, as powder is by opening
There is certain difference in height during dropping in recovery room 116 in mouth 117, powder can be caused to kick up and be diffused into from opening 117
In air, so as to cause the dust pollution of air, therefore at opening 117, it is provided with portable plate 210 and can closes recovery room 116
The opening 117 being in communication with the outside, for convenience the opening ways of operant activity plate 210 be provided with two kinds be respectively hand and from
Dynamic formula, 210 surface of portable plate are divided into left region and right region 210 surface of portable plate at the right region and arrange fluted 211, rotating shaft
212 are arranged at the left region of portable plate 210, now rotating shaft 212 not on the center line of portable plate 210, due to portable plate 210
Surface arranges fluted 211 causes weight imbalance between left region and right region, therefore rotating shaft 212 to be arranged at left region and make
Portable plate 210 keeps balance, it is to avoid due to unbalance cause 210 side of portable plate to tilt higher than table top 112 cannot be with table top
112 flush；Simultaneously in order to avoid leading because particle blocks the gap between portable plate 210 and opening 117
Cause portable plate 210 cannot rotate, now manually 210 side stress of portable plate can be caused portable plate 210 overturn or start and
The motor 213 of the connection of rotating shaft 212, is additionally provided with the motor 213 being connected with rotating shaft 212 in casing 111.
210 surface of portable plate is provided with strain gauge pressure sensor, strain gauge pressure sensor controls motor 213
Keying, when the powder that piles up on portable plate 210 and during excessive particle, strain gauge pressure sensor detects powder to portable plate
After 210 pressure, control motor 213 drives rotating shaft 212 to be rotated automatically, if now there is stuck phenomenon without entering
Row manual pressure causes portable plate 210 to overturn, and portable plate 210 can be caused in the presence of motor 213 by force to overturn.
Cause the transparency of baffle plate 119 as prolonged practicality causes 119 surface of baffle plate of transparence produce spot
Decline, now staff's observation article sight line to be measured is unintelligible to be needed to clean baffle plate 119, if directly in table top 112
On carry out cleaning and be easy to cause the failures such as the short circuit of equipment to occur in casing 111 so that liquid is entered into, therefore baffle plate 119 with
For being detachably connected between lifters 118, the bottom of baffle plate 119 is provided with slot, arranges talented plug 214 in lifters 118,
Baffle plate 119 and lifters 118 can easily be dismantled by the cooperation between slot and plug 214；Simultaneously lifters 118 can be with
The descending operation of baffle plate 119 can achieve for expansion link, 114 lift of hydraulic stem or screw mandrel etc..
While the middle in recovery room 116 is provided with screen pack 310, screen pack 310 can cause 116 points of recovery room
For upper and lower two-layer, in the presence of screen pack 310, powder directly can be dropped by screen pack 310 after entering in recovery room 116
Enter the lower floor of recovery room 116, and granular substance be trapped in the upper strata on screen pack 310 more than powder due to volume simultaneously,
116 inwall of recovery room is provided with the upward-acting door 311 and downward swing door 312 being in communication with the outside, and upward-acting door 311 is located at recovery room 116
Upper strata, downward swing door 312 are located at the lower floor of recovery room 116, when need to take out powder and only needing to during particle open upward-acting door 311 or
Person's downward swing door 312 is taken, so that powder and particle separate process.
The above is only preferred embodiment of the present utility model, and protection domain of the present utility model is not limited merely to
Above-described embodiment, all technical schemes belonged under the utility model thinking belong to protection domain of the present utility model.Should refer to
Go out, for those skilled in the art, some improvement under the premise of without departing from the utility model principle and
Retouching, these improvements and modifications also should be regarded as protection domain of the present utility model.
