Topic.
As shown in Figs. 1-5, above-mentioned feeding mechanism includes receiving hopper 5, temporary hopper 6, open-and-close mechanism 7 and mixer 8；It is temporary
Hopper 6 is connected respectively with receiving hopper 5 and open-and-close mechanism 7, and mixer 8 is mounted in temporary hopper 6；Concrete material is through receiving hopper
5 into keeping in hopper 6, and mixer 8 is stirred the concrete material into mixer 8；Open-and-close mechanism 7 opens temporary material
The discharge port of bucket 6, concrete material are flowed out from discharge port.
In embodiments of the present invention, band connection can be transmitted between hopper 6 and receiving hopper 5 by raw material by keeping in, can also
It is connected by conveyance conduit.When being connected between temporary hopper 6 and receiving hopper 5 by conveyance conduit, the installation position of hopper 6 is kept in
Put the difference in height deposited between the installation site of receiving hopper 5 in vertical direction, as temporary hopper 6 be located at receiving hopper 5 just under
Side.Such conveyance conduit has certain angle of inclination, and conveyance conduit is vertical what is more, in order to which concrete material passes through
Conveyance conduit is delivered to temporary hopper 6 from receiving hopper 5.In addition, the high material of smoothness may be employed in conveying pipeline inner wall, to subtract
Frictional force between small concrete material and conveying pipeline inner wall alleviates concrete material and remains waste material in conveying pipeline inner wall
The problem of material and blocking pipeline.
Above-mentioned receiving hopper 5 has feed inlet and discharge port, and the discharge outlet of receiving hopper 5 is in pass before test block is started from
Closed state.When user starts from test block, user unloads concrete material into receiving hopper 5, and Weighing terminal-pair enters
Concrete material in receiving hopper 5 is weighed.When the weight for determining the concrete material into receiving hopper 5 reaches default threshold
During value, the display of Weighing terminal stops discharging information, and user stops discharging.Industrial control system 1 controls the discharging of receiving hopper 5 at this time
Mouth is opened, and the concrete material in receiving hopper 5 just passes through the raw material conveyer belt or defeated between receiving hopper 5 and temporary hopper 6
Pipeline is sent to be transported in temporary hopper 6.
Similarly, keeping in hopper 6 also has feed inlet and discharge port, and the discharging of hopper 6 is kept in before test block is started from
Mouth is also what is closed.In from the concrete material that receiving hopper 5 is sent from the feed inlet of temporary hopper 6 into temporary hopper 6.
The mixer 8 that the control of industrial control system 1 is mounted in temporary hopper 6 will be stirred evenly into the concrete material in temporary hopper 6.
Industrial control system 1 controls die trial transmission device to be sent to empty die trial 3 below the discharge port of temporary hopper 6 afterwards, and controls folding
Mechanism 7 opens the discharge port of temporary hopper 6.Concrete material in temporary hopper 6 is fallen into sky die trial 3.Industrial control system 1 afterwards
The die trial 3 for filling concrete material is sent to below tamping equipment by control die trial transmission device.
Concrete material remaining in hopper 6 is kept in after being sent away in order to avoid the die trial 3 for filling concrete material to fall
Onto die trial transmission device, after the concrete material in temporary hopper 6 is fallen into sky die trial 3, industrial control system 1 is also controlled and opened
Close the discharge port that mechanism 7 closes temporary hopper 6.
As shown in figure 3, tamping equipment includes concrete vibrating mechanism 9 and elevating mechanism 10；Concrete vibrating mechanism 9 connects with elevating mechanism 10
It connects；Die trial 3 is sent to 9 lower section of concrete vibrating mechanism by die trial transmission device, and concrete vibrating mechanism 9 is pushed into die trial 3, shakes by elevating mechanism 10
Stamper structure 9 vibrates to the concrete material in die trial 3, and the end rear lifting mechanism 10 that vibrates retracts concrete vibrating mechanism 9.
After the die trial 3 for filling concrete material is sent to 9 lower section of concrete vibrating mechanism by die trial transmission device, industrial control system 1
Start elevating mechanism 10, concrete vibrating mechanism 9 is pushed into die trial 3 under the drive of elevating mechanism 10, and industrial control system 1 controls elevator
Structure 10 drives the operation of vibrating of the progress preset duration of concrete vibrating mechanism 9.Under the effect of vibrating of concrete vibrating mechanism 9, the coagulation in die trial 3
Native raw material is compacted.Industrial control system 1 controls elevating mechanism 10 that concrete vibrating mechanism 9 is retracted original position after vibrating.After vibrating,
Industrial control system 1 controls die trial transmission device that die trial 3 is sent to 2 lower section of scraper plate, and controls scraper plate 2 that the concrete after compacting is former
The surface of material strikes off.
As shown in Figure 2-5, which further includes film-covering mechanism 11, label delivery mechanism 12 and RFID (Radio
Frequency Identification, radio frequency identification) card reader 13；After scraper plate 2 strikes off the concrete in die trial 3, die trial
Die trial 3 is sent to 11 lower section of film-covering mechanism, concrete surface cover film of the film-covering mechanism 11 in die trial 3 by transmission device.
Die trial 3 is sent to 12 lower section of label delivery mechanism by die trial transmission device afterwards, and label delivery mechanism 12 pastes electronics mark on film
Label；RFID card reader 13 reads the test block mark on the electronic tag.The embodiment of the present invention is realized by above-mentioned film-covering mechanism 11
Automatic coating and pass through the automatic volume that above-mentioned label delivery mechanism 12 and RFID card reader 13 realize test block in test block manufacturing process
Number.
When scraper plate 2 strikes off the concrete surface in die trial 3, due to containing the stone that particle is larger in concrete material
It influences, striking off rear concrete surface, there may be larger gaps.As shown in figure 3, in order to eliminate the gap of concrete surface, try
Block machine further includes floating device 14；After scraper plate 2 strikes off the concrete in die trial 3, die trial 3 is sent to and smears by die trial transmission device
The lower section of leveling device 14, floating device 14 smooth out the concrete in die trial 3, eliminate concrete and surface covering film it
Between bubble.
As shown in Fig. 1,2,3 and 5, test block machine further includes sky die trial cabinet 15；Be provided in empty die trial cabinet 15 it is several storage every
Between, storage compartments are used to store empty die trial 3.One storage compartments can store one or more empty die trials 3.Start from test block
When, industrial control system 1 controls die trial transmission device to select an empty die trial 3 from empty die trial cabinet 15, and the empty die trial 3 of selection is passed
It send to the discharge port of temporary hopper 6.
Due to that can store multiple empty die trials 3 in empty die trial cabinet 15, institute so as to made in a short time by test block machine
Multiple test blocks.Correspondingly, multiple storage compartments are also provided in curing cabinet 4, each storage compartments can store one or more examinations
Mould 3 conserves multiple test blocks simultaneously by curing cabinet 4.
For example, the empty die trial cabinet 15 of test block machine can include upper and lower two layers of storage compartments, every layer of storage compartments can store 3
A sky die trial 3 can store altogether 6 empty die trials 3.And automatic liter layer device is provided in empty die trial cabinet 15.When taking upper strata
