Description

Technical Field

[0001] The present invention relates to the technical field of concrete charging equipment, and in particular to a concrete mixing station charging system and method. Background Art

[0002] Concrete mixing station, also known as concrete prefabrication plant, is a combined device specially used for centralized mixing of concrete. Concrete mixing station is mainly composed of mixing host, material weighing system, material conveying system, material storage system and control system.

[0003] The existing patent CN114851384A discloses a temporary concrete storage system and method. The temporary concrete storage system includes a concrete feeding device, a concrete storage bin and a concrete discharging device. The present invention can avoid the situation where the concrete mixer truck stays and waits for a long time at the construction site, improve the equipment utilization turnover rate, and at the same time have the conditions for on-site concrete pouring construction at any time, which is conducive to improving construction efficiency and construction quality.

[0004] However, during actual use, the applicant found that at the mixing station, the concrete poured into the mixing barrel into the mixer truck was not enough to fill the entire mixer truck. The mixing barrel needed to be refilled and poured into the mixer truck after mixing. The mixer truck was waiting for filling below, which reduced the transportation efficiency of the mixer truck. Secondly, when the mixer truck did not arrive at the mixing station in time, the concrete in the mixing barrel could not be poured out in time, so the filling and mixing could not continue, which disrupted the set feeding program, thereby leading to the technical problem of reducing the concrete production efficiency. Summary of the invention

[0050] The present invention also discloses a concrete mixing station charging method adapted to a concrete mixing station charging system, which comprises:

[0051] Step 1: Pre-stocking: When the mixer truck is not here, the concrete mixed in the mixing barrel can be transported to the tank through the conveying device for temporary storage, and then poured into the mixer truck when the mixer truck arrives;

[0052] Step 2: Feeding and storage: When the mixing barrel has finished mixing concrete but the mixer truck has not arrived in time, the concrete in the mixing barrel can be transported to the tank for temporary storage through the conveying device;

[0053] Step 3: Stirring and anti-setting: The concrete in the tank body rotates and self-rotates around the stirring shaft through the spiral stirring rod, stirring the concrete in the tank body and prolonging the setting time of the concrete;

[0054] Step 4: Detect discharging: When the mixing barrel pours concrete into the mixer truck, the concrete will lift up the cover, causing the circuit to be disconnected and the indicator light in the distance to go out.

[0056] Step 6. Rinse with clean water: After the work is completed and all the concrete in the tank is discharged, clean water can be poured in to clean the tank and various parts of the conveying device to remove residual concrete and impurities and prepare for the next use.

[0057] The beneficial effects of the present invention are:

[0058] (1) The present invention changes the discharge position of the mixing barrel through the feed control mechanism, so that the concrete poured out of the mixing barrel is transported to the tank body through the conveying device for temporary storage, and the concrete is stirred by the stirring device in the tank body. This solves the problem that when the mixer truck fails to arrive at the mixing station in time due to traffic jams and other factors, the concrete in the mixing barrel cannot be poured out, and the raw materials cannot be refilled into the mixing barrel for stirring according to the set program, which disrupts the work rhythm, and ensures that the mixing of the filler to generate concrete is carried out in an orderly manner.

[0059] (2) The present invention opens the discharge control mechanism to connect the tank body and the conveying device, and the concrete in the tank body is then transported by the conveying device. The feed control mechanism connects the connecting pipe and the discharge inclined pipe, and finally the concrete is poured into the mixer truck from the discharge inclined pipe. This solves the problem that the mixer truck needs to wait for the mixer truck to be refilled and stirred when the mixing barrel is not filled up at one time, which increases the waiting time of the mixer truck. It also reduces the residence time of the mixer truck in the mixing station and increases the efficiency of the mixer truck in transporting concrete.

[0060] (3) The present invention uses an air pressure detection device in conjunction with a conveying device to detect the air pressure and estimate the height of the concrete when pouring concrete into the tank body, thereby preventing excessive concrete from being poured into the tank body. When the concrete in the tank body is conveyed outward, the air pressure detection device can achieve quantitative control of the output concrete.

[0061] In summary, the present invention has the advantages of maintaining the working rhythm and improving the transportation efficiency of the mixer truck. BRIEF DESCRIPTION OF THE DRAWINGS

[0085] Embodiment 1

[0086] like Figure 3-7 As shown, this embodiment provides a concrete mixing station charging system, including a temporary charging device and two groups of mixing barrels 6 arranged in the transverse direction of the temporary charging device;

[0087] The temporary charging equipment comprises:

[0088] A tank body 5, wherein a stirring device 1 for stirring concrete is arranged inside the tank body 5;

[0089] An air pressure detection device 2, which is arranged on the inner wall of the tank body 5 and is used to measure the height of concrete in the tank body 5 by air pressure;

[0090] A conveying device 3, which is disposed at the bottom of the tank body 5 and is used to convey concrete into the tank body 5;

[0091] A discharge detection device 4, which is disposed on the conveying device 3 and is used to monitor whether the concrete has been discharged;

[0092] During the loading process, when the mixer truck 7 is not under the corresponding mixing barrel 6, the conveying device 3 changes the feeding direction of the mixing barrel 6, and reversely feeds the excess material after mixing in the mixing barrel 6 into the tank body 5 through the conveying device 3 for temporary storage; and, when the mixer truck 7 is not full of material, the discharge detection device 4 cooperates with the tank body 5 to pass the material temporarily stored inside it into the mixer truck 7 through the conveying device 3, so that the mixer truck 7 leaves after being fully loaded.

[0093] In detail, there are two situations. One is feeding into the tank body 5. The mixer truck 7 fails to arrive at the mixing station in time due to traffic jams and other factors. At this time, there is no car below the mixing barrel 6. The mixed concrete in the mixing barrel 6 is transported to the tank body 5 for storage through the conveying device 3, and the concrete is stirred by the stirring device 1 arranged inside the tank body 5 to extend the solidification time of the concrete and prevent the concrete from being stratified up and down. The second is discharging from the tank body 5. Since the capacity of the mixer truck 7 for filling concrete is about two to three times the volume of the mixing barrel 6, the mixer truck 7 cannot be filled after all the concrete in the mixing barrel 6 is poured into the mixer truck 7. At this time, the concrete stored in the tank body 5 can be transported to the mixer truck 7 through the conveying device 3. The concrete stored in the tank body 5 can come from two groups of mixing barrels 6. When one group of mixing barrels 6 mixes the concrete and there is no mixer truck 7 below, the concrete can be transported to the tank body 5 through the conveying device 3 for temporary storage, and then transported to the mixer truck 7 below the other group of mixing barrels 6 through the conveying device 3, so as to realize the storage and transportation of the concrete in the two groups of mixing barrels 6.

[0094] It should be noted that a vent is provided at the top of the tank body 5 to ensure that the internal and external pressures are consistent when the concrete is transported into the tank body 5. Support frames are provided at the bottom of the tank body 5 and the bottom of the mixing barrel 6. The conveying device 3 is also installed at the discharge port of the mixing barrel 6 to transport concrete into the tank body 5.

[0095] like Figure 5-6 As shown, the air pressure detection device 2 includes:

[0096] An air chamber 21, wherein the air chamber 21 is disposed at the top of the tank body 5;

[0097] an air pressure detector 22 disposed inside the air chamber 21; and

[0098] The hose 23 is arranged on the inner wall of the tank body 5 , and the top of the hose 23 is connected to the bottom of the air chamber 21 .

[0099] In detail, when concrete is transported into the tank body 5 through the conveying device 3, the concrete will squeeze the hose 23, thereby increasing the pressure inside the air chamber 21. The higher the height of the concrete in the tank body 5, the greater the pressure detected by the air pressure detector 22. The height and mass of the concrete in the tank body 5 have a certain corresponding relationship with the pressure detected by the air pressure detector 22, and the height or mass of the concrete in the tank body 5 can be estimated by the pressure detected by the air pressure detector 22; the air pressure detection device 2 mainly has two functions. First, when concrete enters the tank body 5, when the air pressure detector 22 detects that the air pressure value reaches the air pressure value corresponding to the maximum concrete capacity that can be loaded in the tank body 5, concrete will no longer be transported into the tank body 5; second, concrete is output from the tank body 5 to the mixer truck 7. The reduction in the concrete in the tank body 5 can be estimated by the change in pressure, and a certain amount of concrete can be output to the mixer truck 7 so that the mixer truck 7 is just filled.

[0100] like Figure 5-6 and Figure 8-10 As shown, the conveying device 3 comprises:

[0101] A feeding control mechanism 31, wherein the feeding control mechanism 31 is disposed at the bottom of the mixing barrel 6;

[0102] a delivery pipe 34, wherein the delivery pipe 34 is connected to the feed control mechanism 31 through the connecting pipe 33; and

[0103] A driving motor 35, wherein the driving motor 35 is installed at one end of the conveying pipe 34;

[0104] A screw push rod 36, one end of which is drivingly connected to the output shaft of the drive motor 35;

[0105] The material discharging control mechanism 32 is connected to an end of the conveying pipe 34 away from the driving motor 35 .

[0106] In detail, the conveying device 3 has two main functions: one is to convey the concrete poured from the mixing barrel 6 to the tank body 5 for temporary storage; the other is to convey the concrete stored in the tank body 5 to the mixer truck 7. During the conveying, the function of the feed control mechanism 31 and the discharge control mechanism 32 is to control whether to communicate with the conveying pipe 34. When the feed control mechanism 31 and the discharge control mechanism 32 are both connected to the conveying pipe 34, the drive motor 35 drives the screw push rod 36 to convey the concrete to the tank body 5, or output the concrete from the tank body 5 to the mixer truck 7.

[0107] Wherein, the feed control mechanism 31 comprises:

[0108] A discharge pipe 311, the discharge pipe 311 is connected to the connecting pipe 33;

[0109] A first stepper motor 312, wherein the first stepper motor 312 is installed at the bottom of the discharge pipe 311;

[0110] A first baffle 314, wherein the first baffle 314 is transmission-connected to the output end of the first stepper motor 312 via a first connecting member 313, and two adjacent through slots are formed on the first baffle 314;

[0111] A discharge inclined pipe 315 , one end of which is connected to the discharge pipe 311 .

[0112] In detail, the first stepper motor 312 drives the first baffle 314 to rotate through the first connecting rod 313. The first baffle 314 rotates to different positions to have different effects. First, when the through groove on the first baffle 314 is placed in communication with only the discharging inclined pipe 315, at this time, the mixed concrete in the mixing barrel 6 directly enters the mixer truck 7 through the discharging inclined pipe 315; second, when the through groove on the first baffle 314 is only in communication with the connecting pipe 33, at this time, the concrete in the mixing barrel 6 is transported to the tank body 5 through the conveying device 3 for temporary storage; third, when the two through grooves on the first baffle 314 are respectively in communication with the connecting pipe 33 and the discharging inclined pipe 315, at this time, the concrete in the tank body 5 is transported to the mixer truck 7 through the conveying device 3.

[0113] Among them, the material discharging control mechanism 32 includes:

[0114] A connecting cavity 321, wherein the connecting cavity 321 is provided with a through groove communicating with the delivery pipe 34;

[0115] A second stepper motor 322, wherein the second stepper motor 322 is installed at the bottom of the connecting cavity 321;

[0116] A second baffle 324, wherein the second baffle 324 is drivingly connected to the second stepping motor 322 via a second connecting member 323, and the second baffle 324 is provided with two groups of symmetrical through slots;

[0117] The fixing tube 325 is disposed at the bottom end of the tank body 5 , and is provided with two groups of through grooves corresponding to the second blocking piece 324 .

[0118] In detail, the second stepper motor 322 drives the second baffle 324 to rotate through the second connecting rod 323. The second baffle 324 rotates to different positions and has different effects. First, when the through grooves on the second baffle 324 are aligned with the through grooves on the fixed pipe 325, the tank body 5 is connected to the conveying pipe 34, and concrete can be input into the tank body 5 or output from the tank body 5 through the conveying device 3; second, when the through grooves on the second baffle 324 are completely offset from the through grooves on the fixed pipe 325, the concrete in the tank body 5 can no longer be output, thereby realizing quantitative control of concrete output.

[0119] It should be noted that: when the mixed concrete needs to be stored, the first stepper motor 312 drives the first baffle 314 to rotate through the first connecting rod 313, and the through groove on the first baffle 314 is aligned with the connecting pipe 33 connected to the discharge pipe 311. After the concrete in the mixing barrel 6 falls from the discharge port, it enters the conveying pipe 34 through the connecting pipe 33, and the driving motor 35 drives the connecting pipe 33 in the conveying pipe 34 to rotate, so that the concrete in the conveying pipe 34 is conveyed to the tank body 5;

[0120] When it is necessary to output the concrete in the tank body 5 to the mixer truck 7, the second stepper motor 322 drives the second baffle 324 to rotate through the second connecting rod 323, so that the through groove of the second baffle 324 is aligned with the through groove on the fixed pipe 325, and the first stepper motor 312 drives the first baffle 314 to rotate through the first connecting rod 313 until the two through grooves correspond to the connecting pipe 33 and the discharge inclined pipe 315 respectively, and the pipeline is opened. The concrete in the tank body 5 is then transported to the discharge inclined pipe 315 through the screw push rod 36 in the conveying pipe 34, and then the concrete is poured into the mixer truck 7.

[0121] like Figure 5-7 As shown, the stirring device 1 comprises:

[0122] A reduction motor 11, wherein the reduction motor 11 is arranged on the top of the tank body 5;

[0123] A connecting ring 13, wherein the connecting ring 13 is drivingly connected to the reduction motor 11 through the stirring shaft 12;

[0124] The spiral stirring rod 15 is rotatably connected to the connecting ring 13 via a first bearing 14 , and the spiral stirring rod 15 is driven by a gear set of a speed change mechanism 16 .

[0125] It should be noted that: the speed change mechanism 16 is arranged on the stirring shaft 12, and the stirring shaft 12 is provided with a first gear 161, and the stirring shaft 12 drives the second gear 162 through the first gear 161, and the first gear 161 and the second gear 162 are meshed with each other and the transmission ratio is 3:1, and the second gear 162 is arranged on a second bearing 163, and the second bearing 163 is also provided with a second slave gear 164, and the interior of the second bearing 163 is plugged with a fixed shaft 165, and the fixed shaft 165 is a narrow upper and wide lower structure, so as to prevent the second bearing 16 3 falls off from the fixed shaft 165, the fixed shaft 165 is arranged on the top of the inner wall of the tank body 5, the second slave gear 164 is gear-engaged with a third gear 166, the transmission ratio of the second slave gear 164 to the third gear is 3:1, the third gear 166 is arranged on a third bearing 167, the third bearing 167 is sleeved on the stirring shaft 12, the third bearing 167 is also provided with a third slave gear 168, the third slave gear 168 is gear-engaged with a fourth gear 169, and the fourth gear 169 is arranged on the spiral stirring rod 15.

[0126] In detail, the entire stirring device 1 is powered by the reduction motor 11, the reduction motor 11 drives the stirring shaft 12, and the stirring shaft 12 drives the spiral stirring rod 15 on the connecting ring 13 to rotate, and the spiral stirring rod 15 stirs the concrete in the tank body 5 to prevent the concrete from solidifying;

[0127] While the spiral stirring rod 15 rotates around the stirring shaft 12, the second gear 162 is driven by the first gear 161 arranged on the stirring shaft 12, the second gear 162 drives the second slave gear 164, the second slave gear 164 drives the third gear 166, the third gear 166 drives the third slave gear 168 to drive the fourth gear 169, and the fourth gear 169 drives the spiral stirring rod 15 to rotate around its axis. The rotation of the spiral stirring rod 15 drives the concrete at the bottom of the tank body 5 to move upward to prevent the concrete from being stratified.

[0142] In detail, when the mixing barrel 6 pours concrete into the mixer truck 7, the concrete will push open the cover 411, and the cover 411 will drive the rotating rod 43 and the fixed rod 41 to rotate relative to each other, and the second conductive sheet 410 on the rotating rod 43 is disconnected from the conductive spring 49, resulting in the disconnection of the closed circuit, and the remote control display light goes out. When the concrete is filled, under the pulling action of the tension spring 46, the cover 411 is closed again, and the conductive spring 49 contacts the second conductive sheet 410 again, the circuit is connected, and the display light is on, indicating that the mixing barrel 6 has completed the filling of the mixer truck 7. If the mixer truck 7 is not full, the concrete stored in the tank body 5 can be poured into the mixer truck 7.

[0143] Embodiment 3

[0144] like Fig.14 As shown, a concrete mixing station charging method comprises the following steps:

[0145] Step 1: Pre-stocking: When the mixer truck 7 does not come, the concrete mixed in the mixing barrel 6 can be transported to the tank 5 through the conveying device 3 for temporary storage, and then poured into the mixer truck 7 when the mixer truck 7 arrives;

[0146] Step 2: Feeding and storage: When the mixing barrel 6 finishes mixing concrete and the mixer truck 7 does not arrive in time, the concrete in the mixing barrel 6 can be transported to the tank body 5 for temporary storage through the conveying device 3;

[0147] Step 3: stirring and anti-setting: the concrete in the tank body 5 is stirred by the spiral stirring rod 15 rotating and self-rotating around the stirring shaft 12 at the same time, thereby prolonging the setting time of the concrete;

[0148] Step 4: Detecting the discharge: When the mixing barrel 6 pours concrete into the mixer truck 7, the concrete will push up the cover 411, causing the circuit to be disconnected and the remote indicator light to go out. When the concrete filling is completed, the circuit is closed and the indicator light turns on again, indicating that the concrete filling is completed;

[0149] Step 5: Discharging and filling: When the discharging detection device 4 detects that the concrete in the mixing barrel 6 is filled, if the mixing truck 7 is not full, the concrete in the tank body 5 can be poured into the mixing truck 7 through the conveying device 3, and the discharging amount of the concrete in the tank body 5 can be controlled by the air pressure detection device 2;

[0150] Step 6: Rinse with clean water: After the work is completed and all the concrete in the tank body 5 is discharged, clean water can be poured in to clean the tank body 5 and various parts of the conveying device 3 to remove residual concrete and impurities, so as to prepare for the next use.
