It should be noted that the features of the embodiments of the present invention may be combined with each other without conflict.
Example one
The embodiment provides a concrete distributing method, which is used for a concrete distributing machine 010; referring to fig. 1, the concrete spreader 010 includes a hopper 120, a blanking member 110 disposed at an outlet of the hopper 120, and a driving assembly 100 in transmission connection with the blanking member 110, wherein the driving assembly 100 is configured to drive the blanking member 110 to drive the concrete in the hopper 120 to fall out of the outlet; the concrete distribution method comprises the following steps: acquiring the actual current of the driving assembly 100; when the actual current is greater than the preset current, the driving assembly 100 is controlled to stop operating.
The concrete distributing method of the embodiment can obtain the actual current of the driving assembly 100 during discharging, and further compare the actual current with the preset current, when the discharging piece 110 is stuck, the current of the driving assembly 100 is continuously increased, and when the actual current of the driving assembly 100 is larger than the preset current, the driving assembly 100 is controlled to stop operating, namely, discharging is stopped; therefore, the blanking clamp can be automatically judged to be dead without manual observation, and the blanking clamp can be automatically stopped when the clamp is dead.
Referring to fig. 2, the driving assembly 100 includes a motor, the concrete spreader 010 further includes a frequency converter electrically connected to the motor, the discharging member 110 includes a screw rod, the screw rod is located at an outlet of the hopper 120, an output shaft of the motor is in transmission connection with the screw rod, and when the output shaft of the motor rotates, the screw rod is driven to rotate around its own axis, so that the concrete in the hopper 120 falls out from the outlet.
When the screw rod is stuck by the concrete in the hopper 120, the actual current of the motor is continuously increased, and when the actual current of the motor is greater than the preset current of the frequency converter, namely when the actual current of the motor is greater than the rated current of the frequency converter, the frequency converter is powered off protectively, so that the motor is powered off synchronously, the screw rod does not rotate any more, namely the driving assembly 100 stops operating; thus, the concrete spreader 010 can automatically determine the dead-locking condition of the blanking part 110 through the frequency converter, and automatically stops when the blanking part 110 is dead-locked.
Therefore, when the concrete distributing method provided by the embodiment is used for distributing relatively dry concrete or concrete containing some large particles, the condition that the blanking part 110 is stuck by the concrete in the hopper 120 can be avoided, and further, a certain protection effect can be achieved on the motor serving as the driving assembly 100.
The concrete distribution method of the embodiment may further include: after the step of controlling the driving assembly 100 to stop operating when the actual current is greater than the preset current, controlling the driving assembly 100 to reversely drive the discharging member 110; after the hob is died by the card promptly, converter control motor outage is shut down, then the output shaft upset of motor to drive hob antiport, thereby realize the automatic dead condition of card of clearance hob.
The concrete distributing method of the embodiment further comprises the following steps: when the actual current is smaller than the preset current, controlling the driving assembly 100 to improve the operation efficiency; thus, when distributing concrete with low concentration by using the concrete distributor 010, the speed of the driving assembly 100 for driving the discharging piece 110 to discharge from the outlet of the hopper 120 can be increased, so that the problems of uneven and unstable distribution are avoided.
It should be noted that the actual current of the driving assembly 100 being smaller than the preset current means that the actual current of the driving assembly 100 as a motor does not exceed the rated current of the inverter, that is, the inverter does not need automatic power-off protection.
Further, referring to fig. 3, the concrete spreader 010 further includes a weighing assembly 130, wherein the weighing assembly 130 is disposed in the hopper 120 and is configured to detect a weight of concrete in the hopper 120; the concrete distributing method provided by the embodiment further comprises the following steps: when the actual current is less than the predetermined current and the weight reduction rate detected by the weighing component 130 is greater than the predetermined reduction rate, the driving component 100 is controlled to improve the operation efficiency. It should be noted that, when the actual current is less than the preset current and the weight reduction rate detected by the weighing component 130 is greater than the preset reduction rate, it indicates that the rate at which the driving component 100 drives the discharging component 110 to drive the concrete output hopper 120 in the hopper 120 is less than the rate at which the concrete in the hopper 120 falls out of the hopper 120 under the action of the self-weight, that is, it indicates that the concrete in the hopper 120 is thinner and the concrete almost falls out of the hopper 120 under the action of the self-weight, and the driving component 100 drives the discharging component 110 to drive the concrete output hopper 120 has an extremely low effect, uneven distribution and poor effect.
So set up to through the weight reduction rate of the interior concrete of hopper 120 of weighing component 130 feedback, confirm more accurately that the speed that drives unloading piece 110 at drive assembly 100 and drive concrete output hopper 120 is less than the speed that the concrete falls out automatically under the effect of dead weight, and then accurate control drive assembly 100 improves the running speed of unloading piece 110, make drive assembly 100 drive unloading piece 110 drive the speed that the interior concrete output hopper 120 of hopper 120 exported and match the degree of doing rarity of concrete, thereby make the more even whereabouts of concrete in the hopper 120.
The type of the weighing assembly 130 may be selected as desired, and may be, for example, a load cell or the like.
It should be noted that, referring to fig. 3, in this embodiment, the concrete spreader 010 may further include a controller 300 electrically connected to the weighing assembly 130, and the controller 300 is electrically connected to the driving assembly 100, so that the controller 300 may control the driving assembly 100 to drive the blanking member 110 to increase the blanking rate according to the blanking rate fed back by the weighing assembly 130.
The concrete distributing method of the embodiment further comprises the following steps: when the driving element 100 is controlled to increase the operating efficiency so that the actual current is changed from being less than the predetermined current to being equal to the predetermined current, the operating efficiency of the driving element 100 is maintained; in this way, the concrete in the hopper 120 is driven by the blanking member 110 to be discharged to the outlet of the hopper 120, and is distributed uniformly and stably.
It should be noted that the number of the blanking members 110 and the corresponding driving assemblies 100 can be selected according to the requirement; the concrete spreader 010 of the embodiment has 8 sets of blanking members 110 and driving assemblies 100, one driving assembly 100 is correspondingly arranged on one blanking member 110, each driving assembly 100 is correspondingly electrically connected with one frequency converter, and each driving assembly 100 prevents the corresponding blanking member 110 from being locked through the corresponding frequency converter. The concrete spreader 010 involved in other embodiments may further have 4, 6, 7, etc. sets of the blanking members 110 and the driving assemblies 100.
The concrete distributing method provided by the embodiment is used for a concrete distributing machine 010, and can automatically judge whether the blanking part 110 is jammed according to the actual current of the driving assembly 100 when the driving assembly 100 drives the blanking part 110 to drive the concrete output outlet in the hopper 120, when the blanking part 110 is jammed by the concrete, the current of the driving assembly 100 is continuously increased until the current of the driving assembly 100 is greater than the preset current of the frequency converter, namely the rated current of the frequency converter, the frequency converter drives the driving assembly 100 to be powered off and shut down, even if the driving assembly 100 stops running, so that the blanking part 110 is prevented from being jammed, and the driving assembly 100 is prevented from being damaged; in the method of this embodiment, after the blanking member 110 is jammed and the driving assembly 100 stops operating, the driving assembly 100 drives the blanking member 110 to rotate reversely to clean the jammed impurities. The concrete distributing method provided in this embodiment may further include when the concrete is relatively thin, when the speed at which the driving assembly 100 drives the discharging member 110 to drive the concrete output hopper 120 is less than the speed at which the concrete automatically falls out under the action of the dead weight, that is, the concrete basically falls out of the outlet of the hopper 120 by the dead weight, but the driving assembly 100 does not basically drive the discharging member 110 to drive the contaminated concrete to fall out of the outlet of the hopper 120, when the actual current of the driving assembly 100 is less than the preset current, and the weight reduction speed detected by the weighing assembly 130 is greater than the preset speed, controlling the driving assembly 100 to improve the operation efficiency, so that the speed at which the driving assembly 100 drives the discharging member 110 to drive the concrete output hopper 120 matches the dry and thin degree of the concrete, thereby uniformly and stably discharging the concrete.
In summary, the concrete distributing method provided by the invention can obtain the actual current of the driving assembly 100 during discharging, and further compare the actual current with the preset current, when the discharging piece 110 is stuck, the current of the driving assembly 100 is continuously increased, and when the actual current of the driving assembly 100 is greater than the preset current, the driving assembly 100 is controlled to stop operating, that is, discharging is stopped; therefore, the blanking clamp can be automatically judged to be dead without manual observation, and the blanking clamp can be automatically stopped when the clamp is dead.
Example two
Referring to fig. 1 and 3, the present embodiment provides a concrete spreader 010, including: the concrete feeding device comprises a hopper 120, a blanking member 110 arranged at an outlet of the hopper 120 and a driving assembly 100 in transmission connection with the blanking member 110, wherein the driving assembly 100 is used for driving the blanking member 110 to drive concrete in the hopper 120 to fall out from the outlet; the concrete spreader 010 further includes a controller 300, the controller 300 being electrically connected to the driving assembly 100, the controller 300 being configured to: acquiring the actual current of the driving assembly 100; when the actual current is greater than the preset current, the driving assembly 100 is controlled to stop operating.
The controller 300 of the concrete spreader 010 provided by the embodiment of the invention can obtain the actual current of the driving assembly 100, when the blanking member 110 is stuck, the current of the driving assembly 100 is continuously increased, and when the actual current of the driving assembly 100 is larger than the preset current, the driving assembly 100 is controlled to stop operating, namely, blanking is stopped; therefore, the situation that the blanking is blocked can be automatically judged without manual observation, and the blanking machine is automatically stopped when the blanking is blocked.
Referring to fig. 2, the feeding member 110 of the present embodiment includes a screw rod, the driving assembly 100 includes a motor, and an output shaft of the motor is in transmission connection with the screw rod, that is, when the output shaft of the motor rotates, the screw rod is driven to rotate around its own axis, so that the rotating screw rod drives the concrete in the hopper 120 to fall out from the outlet of the hopper 120.
Further, the motor is electrically connected to the controller 300, so that the controller 300 controls the output shaft of the motor to have different rotation speeds, so as to drive the screw rod to output the concrete in the hopper 120 at different rotation speeds.
Still further, the motor may be electrically connected to the controller 300 through a frequency converter, so that the controller 300 collects real-time current, i.e., actual current, through the frequency converter, and the frequency converter may further perform overload protection on the driving assembly 100 when the controller 300 fails or malfunctions.
The controller 300 is further configured to: after the step of controlling the driving assembly 100 to stop operating when the actual current is greater than the preset current, controlling the driving assembly 100 to reversely drive the discharging member 110. Thus, the blocked blanking part 110 is automatically cleaned through the reverse rotation of the blanking part 110, so that the subsequent concrete distribution work is conveniently carried out.
The concrete spreader 010 of the embodiment includes at least two blanking members 110 and at least two driving assemblies 100, the at least two blanking members 110 and the at least two driving assemblies 100 are disposed in a one-to-one correspondence, each driving assembly 100 is electrically connected to a controller 300, the actual current is the average current of all the driving assemblies 100, and the controller 300 is further specifically configured to: when the average current is larger than the preset current, controlling all the driving components 100 to stop operating; thus, when only one blanking member 110 is locked or some blanking members 110 are locked and other blanking members 110 are not locked, the controller 300 can control all the driving assemblies 100 of the whole concrete spreader 010 to stop, i.e., the concrete spreader 010 is stopped, so that the driving assemblies 100 of the concrete spreader 010 can be protected on one hand, and the problem of uneven spreading can be avoided on the other hand.
The controller 300 described above is further configured to: after the average current is greater than the preset current and all the driving assemblies 100 are controlled to stop operating, all the driving assemblies 100 are controlled to reversely drive the corresponding blanking pieces 110. So set up, can be in the dead back of shutting down of unloading piece 110 card, through the reversal of unloading piece 110, the dead circumstances of automatic clearance concrete spreader 010 card to carry out subsequent work.
The controller 300 is further configured to: when the increase rate of the actual current of the driving assembly 100 is greater than the preset increase rate, but the actual current does not exceed the preset current, the driving assembly 100 is controlled to drive the blanking piece 110 to reduce the blanking rate, so as to prevent the blanking piece 110 from being stuck by the concrete in the hopper 120; if the increasing rate of the actual current of the driving assembly 100 is still not reduced to be less than or equal to the preset increasing rate after the driving assembly 100 drives the blanking piece 110 to reduce the speed, controlling the driving assembly 100 to stop and reversely drive the blanking piece 110 when the actual current is greater than the preset current; if the increasing rate of the actual current of the driving assembly 100 is less than or equal to the preset increasing rate after the driving assembly 100 drives the blanking member 110 to decrease the speed, the driving assembly 100 does not need to be controlled to stop or reverse. So set up, can avoid concrete spreader 010 card dead on the one hand, on the other hand can avoid reducing the efficiency of concrete spreader 010 cloth.
The controller 300 described above is further configured to: when the actual current is smaller than the predetermined current, the driving device 100 is controlled to improve the operation efficiency.
Further, when the actual current of all the driving assemblies 100 of the concrete spreader 010 is smaller than the preset current, all the driving assemblies 100 are controlled to improve the operation efficiency, so that the speed of all the driving assemblies 100 driving the discharging member 110 to drive the concrete in the hopper 120 to be output can meet the dryness and dilution degree of the concrete. When the concrete in the hopper 120 is relatively thin, the concrete falls out of the outlet of the hopper 120 by the dead weight, but rarely falls out of the outlet of the hopper 120 by the driving assembly 100 driving the discharging member 110, that is, when the speed of the driving assembly 100 driving the discharging member 110 to drive the concrete discharging hopper 120 is less than the speed of the concrete automatically falling out under the dead weight, the actual current of the driving assembly 100 is less than the preset current, and the controller 300 can control the driving assembly 100 to increase the operation speed of the discharging member 110, so that the speed of the driving assembly 100 driving the discharging member 110 to drive the concrete discharging hopper 120 matches the dry and thin degree of the concrete, thereby uniformly and stably discharging.
Referring to fig. 3, the concrete spreader 010 of the embodiment further includes a weighing component 130, the weighing component 130 is electrically connected to the controller 300, the weighing component 130 is disposed on the hopper 120, and the controller 300 is further configured to: when the actual current is less than the predetermined current and the weight reduction rate detected by the weighing component 130 is greater than the predetermined reduction rate, the driving component 100 is controlled to improve the operation efficiency. Thus, the weight reduction rate in the hopper 120 fed back to the controller 300 by the weighing assembly 130 can be used to more accurately determine that the concrete in the hopper 120 is output from the outlet of the hopper 120 under the action of the self-weight, and the driving assembly 100 can drive the discharging member 110 to output the concrete to the hopper 120 with a minimum effect, so that the driving assembly 100 can be accurately controlled to increase the speed of the discharging member 110 to output the concrete to the hopper 120, thereby uniformly and stably distributing the material.
The controller 300 described above is further configured to: controlling the driving element 100 to increase the operating efficiency until the actual current is equal to the predetermined current, and maintaining the operating efficiency of the driving element 100; in this way, the concrete in the hopper 120 is driven by the blanking member 110 to be discharged to the outlet of the hopper 120, and is distributed uniformly and stably.
It should be noted that, the concrete spreader 010 of this embodiment may further enter a material mixing ratio of the concrete to be spread, so as to match an appropriate material spreading rate according to the material mixing ratio; further, the controller 300 is further configured to receive a batching ratio of the concrete to be batched, and match an appropriate feeding rate according to the batching ratio of the concrete, so as to control the driving assembly 100 to drive the feeding member 110 to output the concrete at a matched rate;
it should be further noted that the blending ratio of the concrete may be the dry degree of the concrete, or the content of the broken stones in the concrete, for example: when the concrete is dry or the crushed stone content is high, the controller 300 controls the driving assembly 100 to drive the blanking part 110 to distribute at a low speed; when the concrete is wet or the crushed stone content is low, the controller 300 controls the driving assembly 100 to drive the discharging member 110 to distribute material at a faster rate.
It should be noted that the concrete spreader 010 of the embodiment further includes a switch, and the switch is electrically connected to the motor of the driving assembly 100 and the controller 300 at the same time, so that the actual current of the motor is read by the switch and is transmitted to the controller 300.
When the concrete spreader 010 provided by this embodiment is used, the batching information of the concrete to be spread can be recorded first, and the controller 300 receives the batching information of the concrete; the controller 300 controls the driving assembly 100 to drive the blanking member 110 to output the concrete at an appropriate rate according to the batching information of the concrete; when the controller 300 receives that the average current of all the driving assemblies 100 is greater than the preset current, all the driving assemblies 100 are controlled to stop, and then the blanking part 110 is driven to rotate reversely so as to automatically clean when the blanking part 110 is stuck; or, when the controller 300 receives that the actual current of each driving assembly 100 is less than the preset current and the rate of weight reduction fed back by the weighing assembly 130 is greater than the preset reduction rate, controlling the driving assembly 100 to drive the blanking member 110 to increase the blanking rate, and controlling the driving assembly 100 to keep the running rate until the actual current of each driving assembly 100 is equal to the preset current.
In summary, the controller 300 of the concrete spreader 010 according to the embodiment of the present invention can obtain the actual current of the driving assembly 100, when the blanking element 110 is stuck, the current of the driving assembly 100 is continuously increased, and when the actual current of the driving assembly 100 is greater than the preset current, the driving assembly 100 is controlled to stop operating, that is, to stop blanking; therefore, the situation that the blanking is blocked can be automatically judged without manual observation, and the blanking machine is automatically stopped when the blanking is blocked.
Referring to fig. 4, the present embodiment further provides a control device 020 for the concrete spreader 010, including: an obtaining module 210, configured to obtain an actual current of the driving assembly 100; the execution module 220 controls the driving component 100 to stop operating when the actual current is greater than the predetermined current.
It should be noted that, the execution module 220 may further control the driving assembly 100 to drive the blanking member 110 to rotate reversely after controlling the driving assembly 100 to stop operating, so as to automatically clear the jammed condition of the blanking member 110.
In summary, the control device 020 according to the embodiment of the present invention can obtain the actual current of the driving assembly 100 through the obtaining module 210, when the blanking element 110 is stuck, the current of the driving assembly 100 is continuously increased, and when the actual current of the driving assembly 100 is greater than the preset current, the execution module 220 controls the driving assembly 100 to stop operating, that is, to stop blanking; therefore, the blanking clamp can be automatically judged to be dead without manual observation, and the blanking clamp can be automatically stopped when the clamp is dead.
The embodiment further provides a concrete distributing method, which is used for the concrete distributor 010.
Referring to fig. 5, the concrete distribution method includes:
s100: the actual current of the driving assembly 100 is obtained.
At the time of distribution of the concrete distributor 010, the exchanger electrically connected to the driving assembly 100 can read an actual current of the driving assembly 100, that is, a real-time current, and deliver the actual current to the controller 300.
S201: when the actual current is greater than the preset current, the driving assembly 100 is controlled to stop operating.
The actual current of the driving assembly 100 received by the controller 300 is greater than the preset current, which indicates that the blanking member 110 is locked in transmission connection with the driving assembly 100, and thus the driving assembly 100 can be controlled to stop operating.
When the concrete spreader 010 operates, after the controller 300 receives the real-time current of all the driving assemblies 100, the real-time average current can be calculated, the average current is used as the actual current, and when the average current as the actual current is larger than the preset current, the controller 300 controls all the driving assemblies 100 to stop operating.
After the blanking member 110 is jammed and the driving assembly 100 stops operating, the controller 300 may control the driving assembly 100 to drive the blanking member 110 to rotate reversely, so as to clear the jam of the blanking member 110.
S202: when the actual current is smaller than the predetermined current, the driving device 100 is controlled to improve the operation efficiency.
When the actual current received by the controller 300 from the driving assembly 100 is smaller than the preset current, it is indicated that the concrete in the hopper 120 is thinner, and the concrete is output from the hopper 120 under the action of the self-weight, and the driving assembly 100 drives the discharging member 110 to output the concrete to the hopper 120 with a smaller action, at this time, the discharging speed of the driving assembly 100 driving the discharging member 110 is increased, so that the concrete in the hopper 120 is output from the discharging member 110 to the hopper 120, and uniform and stable distribution is ensured.
Further, when the actual current is smaller than the predetermined current and the weight reduction rate detected by the weighing component 130 is greater than the predetermined reduction rate, the driving component 100 is controlled to improve the operation efficiency. In this way, it can be more accurately determined by the weighing assembly 130 that the relatively dilute concrete in the hopper 120 is substantially discharged out of the hopper 120 by the action of its own weight, while the drive assembly 100 drives the blanking member 110 to discharge the concrete out of the hopper 120 with less effect.
It should be noted that, when the distributing speed of the driving assembly 100 driving the discharging member 110 to output the concrete is increased until the actual current of the driving assembly 100 is equal to the preset current, the operation efficiency of the driving assembly 100 is maintained. It should be further noted that, the above-mentioned actual currents up to the driving elements 100 are equal to the preset current, which may mean that the actual currents of all the driving elements 100 are equal to the preset current.
In summary, the concrete distributing method provided by the invention can obtain the actual current of the driving assembly 100 during discharging, and further compare the actual current with the preset current, when the discharging piece 110 is stuck, the current of the driving assembly 100 is continuously increased, and when the actual current of the driving assembly 100 is greater than the preset current, the driving assembly 100 is controlled to stop operating, that is, discharging is stopped; therefore, the blanking clamp can be automatically judged to be dead without manual observation, and the blanking clamp can be automatically stopped when the clamp is dead.
The above description is only for the specific embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the appended claims.
