At truncated cone circle mould height about 2/3rds, each stroke of both direction is being mutually perpendicular to 5 times with pocket knife, it is equal by edge to center with tamper
It is even to smash pressure 15 times, second layer glue sand then is filled, is filled to and is higher by truncated cone circle mould about 20mm, 10 times are drawn again with tamper by edge with pocket knife
Pressure is uniformly smash to center 10 times.Smashing amount of pressure should be enough to make glue sand just full of truncated cone circle mould.Pressure depth is smash, first layer is smash to glue
The half of sand height, second layer tamping, which is no more than, has consolidated bottom surface.Dress glue sand and when smashing pressure, with hand steered steady die trial,
It not move it.Step 4：Smash pressure to finish, remove die sleeve, truncated cone circle mould will be higher by twice from centre to edge with pocket knife
Glue sand scrape off floating, wipe glue sand on the table.Truncated cone circle mould is gently lifted vertically upward.Jumping table is started at once,
About each second once, completes 30 bounces in 30 ± 1s.Step 5：Bounce finishes, and is expanded with kind of calliper glue sand bottom surface is maximum
Diameter and the diameter vertical with base are dissipated, calculates average value, round numbers, with being represented in units of mm.The as cement mortar of the water
Fluidity.
It follows that this assay method can not accurately, quickly determine to smash pressure position, glue sand filling position above.

Embodiment
The utility model is further described below in conjunction with the accompanying drawings, the scope of protection of the utility model be not limited to
It is lower described：
As shown in Figure 1 and 2, a kind of positioner for determining flow of cement mortar, it includes tamper 1, locating rod 2, positioning
Ring 3 and bolt 4, described locating rod 2 is horizontally disposed, and the length of locating rod 2 is more than the large end face external diameter of die sleeve 6, locating rod 2
On be provided with locating ring 3, the mode such as locating rod 2 and locating ring 3 are by welding, riveting, bolt connection is connected, described locating ring
3 are set parallel to locating rod 2, and bolt hole 5, bolt hole 5 and 2 opposed setting of locating rod, bolt hole 5 are provided with locating ring 3
Internal thread is connected with bolt 4, and the diameter of tamper 1 is less than the internal diameter of locating ring 3, and tamper 1 is vertical to be set through locating ring 3, tamper 1
Bottom be provided with scale, scale bottommost numerical value is 0, and scale top numerical value is 100mm, and scale division value is 1mm.When
During screwed in place bolt 4, the head of bolt 4 is pressed on tamper 1 so that tamper 1 is lock onto in locating ring 3；It is fixed when unscrewing
During the bolt 4 of position, the head of bolt 4 is separated with tamper 1 to realize that tamper 1 moves freely in locating ring 3.
As shown in figure 3, the localization method of the positioner of described measure flow of cement mortar, it is characterised in that：It
Including following：
S1, first layer glue sand load the determination of position, and it is concretely comprised the following steps：First by locating rod 2 across frame on the top of die sleeve 6
Portion；The vertical insertion truncated cone in graduated one end on tamper 1 is justified into the bottom of mould 7 again, sight is concordant with the top surface of die sleeve 6 with from quarter
The summation height of die sleeve 6 and truncated cone circle mould 7, summation height abbreviation combined altitudes are read on degree；Tamper 1 is moved then up, together
When sight it is concordant with the top surface of die sleeve 6 to read scale numerical value, when scale numerical value=combined altitudes-（Die sleeve height+truncated cone justifies mould
/ 3rd height）When, stop mobile tamper 1 and screwed in place bolt 4 is so that bolt 4 locks tamper 1, most backward truncated cone
Glue sand is loaded in circle mould 7, when glue sand is filled into 0 scale, that is, ensure that first layer glue sand is accurately loaded to truncated cone circle mould height
At 2/3rds height；
S2, first layer glue sand smash the determination of pressure position, and it is concretely comprised the following steps：Unscrew bolt 4 and make tamper 1 to moving down
It is dynamic, while sight is concordant with the top surface of die sleeve 6 to read scale numerical value, when scale numerical value=combined altitudes-（Die sleeve height+the first
Layer glue sand half height）When, stop mobile tamper 1 and screwed in place bolt 4 is so that bolt 4 locks tamper 1, now
0 scale pointed location is that first layer glue sand smashes pressure position, and first layer glue sand is carried out smashing pressure using tamper 1, is smash after pressure terminates,
First layer glue sand smashes the half that pressure height is just equal to first layer glue sand height；
S3, second layer glue sand load the determination of position, and it is concretely comprised the following steps：First unscrew bolt 4 and make tamper 1 upward
Move on to outside truncated cone circle mould 7 and the assembly of die sleeve 6, move tamper 1 still further below, while sight is concordant with the top surface of die sleeve 6 with reading
Take scale numerical value, when scale numerical value=combined altitudes-（Truncated cone circle mould height+20mm）When, stop mobile tamper 1 and screwed in place
Bolt 4 is so that bolt 4 locks tamper 1, and most backward truncated cone circle mould 7 is interior to load glue sand, when glue sand is filled into 0 scale, i.e.,
It ensure that second layer glue sand accurately to truncated cone circle mould 20mm is higher by highly locate by filling；
S4, second layer glue sand smash the determination of pressure position, and it is concretely comprised the following steps：Unscrew bolt 4 and make tamper 1 to moving down
It is dynamic, while sight is concordant with the top surface of die sleeve 6 to read scale numerical value, it is ensured that scale numerical value<（Combined altitudes-first layer glue sand
Smash pressure height）, then stop mobile tamper 1 and screwed in place bolt 4 be so that bolt 4 locks tamper 1, now 0 quarter
Degree pointed location is that second layer glue sand smashes pressure position, finally second layer glue sand is carried out smashing pressure using tamper 1, smashes pressure and terminate
Afterwards, it accurately ensure that the second layer is smash pressure depth and is no more than and smash pressure depth surface.
Therefore first layer glue sand can be loaded accurately and rapidly to truncated cone to justify mould height three points by the positioner
Two opening positions；Second layer glue sand load to be higher by truncated cone circle mould 20mm opening positions；First layer smashes pressure depth to first layer glue sand
The half of height；The second layer, which is smash pressure depth and is no more than, has smash pressure depth surface.
