When the hydraulic motor 503 drives the bucket loading device 6 to rotate through the gear 502 and the like, the shaft of the encoder 504 also rotates, so that a pulse signal is transmitted to the control electronic box to feed back the position of the bucket loading device 6.

Fig. 9 is a schematic structural diagram of the main planetary driving mechanism 4 and the bucket loading device 6 according to an embodiment of the present invention. The main planetary driving mechanism 4 is arranged on the integral support and the track 5 and can rotate on the integral support and the track 5; a hopper carrying device 6 for carrying the hopper is arranged on the main planetary drive 4 to move the hopper to different stations.

The primary planetary drive 4 comprises the following components:

the integral support 401: the bracket is mainly formed by welding I-shaped steel according to the design requirement. The bearing and connecting functions are achieved. The integral support 401 has four ends corresponding to the four stations, respectively.

The moving wheel 404: the bottom surface of each end of the integral support 401 can be provided with 2 moving wheels 404, and the total number of the main planetary drive mechanism 4 is 8; the moving wheel 404 runs on the integral support and the circular track of the track 5, and mainly has the function of reducing resistance when the whole mechanism rotates, and is easy to start.

Driven pulley 405: is provided in the center of the integral support 401. The driven wheel is in meshed connection with a gear 502. The hydraulic motor 503 drives the gear 502 as the driving wheel to output power, so as to drive the driven wheel 405 to rotate, and the driven wheel 405 and the integral support 401 are fixed together, so as to drive the integral support 401 to rotate, and finally realize the rotation of the whole main planetary drive mechanism 4.

The buffer rubber column 406: optionally, a plurality of cushion rubber columns 406 may be disposed at appropriate positions of the integral support 401, and the cushion rubber columns 406 are engaged with the blocking shafts 302 of the blocking mechanism 3. Specifically, the number of the buffer rubber columns can be 4. When the main planetary driving mechanism 4 drives the bucket loading device 6 to reach the No. 2 station each time, the buffer rubber column 406 extrudes the stop shaft 302 due to the motion inertia to play a buffer role. And, the below can further be equipped with the locating piece, only need adjust the locating piece position, only need cooperate the fender axle to use, just can decide the inaccurate problem of fill position that falls on automatic cleaning system and the transport vechicle.

The number of the bucket devices 6 is 4, and the bucket devices are respectively arranged on four ends of the integral support 401 of the main planetary drive mechanism 4. The bucket loading device 6 may include:

the liftable platform 601: the platform is primarily used to receive a hopper, detachably mounted at the end of the integral support 401. The lifting platform can be supported by other power mechanisms to move up and down within a required range so as to achieve the required effect.

The stop block assembly 602: the liftable platform 402 is provided with a plurality of stop block assemblies 602 for positioning the loaded hopper. The limiting block assembly 602 is used for preventing the hopper from moving when the hopper is placed on the hopper carrying device, so that the hopper can be smoothly taken and placed at each time, and the safety protection effect is realized. This subassembly is 16 groups total, sets up 4 groups on every liftable platform 402, and every group comprises 4 ladder metal block, and the inclined plane of every metal block is inside, encloses the synthetic recess of big-end-up, and the primary function makes in the foot stool of hopper can get into this subassembly smoothly encloses synthetic recess, carries on spacingly to the foot stool of hopper, prevents that the hopper from removing.

In some embodiments, the operation process of the automatic cleaning system of the present invention comprises the following steps:

s01, at the beginning, empty hoppers are arranged on the stations 1, 3 and 4 of the automatic cleaning system.

And S02, when the control center operator presses the blanking key, executing the following operations.

S03, the automatic cleaning system controls an electric box (controller) to output signals, so that a hydraulic station is started to enable a hydraulic cylinder 104 of a station No. 1 to be lifted, the hydraulic cylinder pushes a lifting platform 601 of the station to leave an integral support 401, and a weighing mechanism 1 of the station can weigh the weight of the lifting platform and a bucket at the same time and automatically weigh and peel the bucket; and open unloader, when the concrete falls to in the fill, weighing mechanism can return weight information in real time, if reach appointed weight, can close unloader immediately and stop the unloading. The automatic cleaning system controller again outputs a signal to cause the hydraulic station to control the hydraulic cylinder to descend until the lower position is sensed to be in place 107. At this time, the liftable platform 601 is already returned to the integral support 401 to wait for the next operation.

S04, when the station No. 1 is used for blanking, a transport vehicle is already used for driving a hopper needing to be cleaned to the position above the station No. 2. After the transport vehicle is aligned with the position and stops, the automatic cleaning system controls the electric box to output signals, so that the hydraulic cylinder 203 of the No. 2 station of the hydraulic station is started to lift the lifting platform 601 of the station until the sensor is in place. After the hopper is lifted to a specified height, the hopper foot plate can be contacted with the lifting platform panel; if the hopper has slight aversion, stopper subassembly 602 will be functional this moment, and the inclined plane of stopper can touch the hopper sole to revise the hopper and put the position at liftable platform. After the liftable platform takes the hopper to rise to highest position sensor, the automatic cleaning system controller can send a signal and open for transport handlebar lock fill device, and the transport vechicle can send a signal and give automatic cleaning system after opening the completion, and system control electronic box output signal makes hydraulic pressure station start-up hydraulic cylinder 203 descend and targets in place until sensor 204, and on liftable platform also can get back to whole support 401 simultaneously, after above action was accomplished, the transport vechicle left No. 2 stations.

S05, after all the actions are finished, the sensor 902 of the No. 2 station checks whether the position of the hopper and the hopper on the lifting platform 601 of the station is correct; when the determination signal is received, the system controls the cylinder 304 to retract the gear shaft 302 until the descent-to-position sensor 305 is triggered, and then the PLC instructs the hydraulic motor to drive the main planetary driving mechanism 4 to rotate, so that the hopper loading device 6 loaded with an empty hopper is rotated away from the transport vehicle, and at the same time, the encoder 504 immediately returns a rotation message to the controller. When the hopper device rotates to a specified position, the controller can start the air cylinder 304 again to lift the blocking shaft until the rising position sensor 303 is triggered, and at the moment, the main planetary driving mechanism 4 continues to rotate until the buffer rubber column on the hopper device is extruded to the blocking shaft 302.

S06, at the moment, the position of the upper bucket of the main planetary driving mechanism 4 is just changed to another position, the original hopper which is full of materials just below the station 1 is just turned to the position below the station 2 transport vehicle and triggers the sensor 902, the control electronic box controls the hydraulic cylinder 203 of the station 2 to lift the lifting device, so that the lifting platform 601 and the hopper are lifted together until the sensor 205 is triggered, the automatic cleaning system sends a signal to the transport vehicle after the sensor 205 is triggered, and the bucket selling device on the vehicle is used for selling and returning the signal to the cleaning system; the system will again actuate cylinder 203 to lower the lift device until sensor 204 is triggered and a signal is sent to the vehicle, at which point the vehicle will leave the cleaning system.

And S07, when the loading bucket and the station No. 1 receive a blanking instruction, blanking is carried out according to the step S03.

S08, on the other hand, when the station sensor 903 No. 3 is triggered at the same time, the system starts the bucket opening motor and rotates anticlockwise, and the bucket opening arm is rotated through the coupler until the bucket closing sensor is triggered; the purpose is to push the arm of the hopper first and reduce the tension of the bucket locking device; and then the hook opening cylinder is started, the push rod is pushed forwards until the cylinder is triggered to move forwards, and when the push rod is pushed forwards, the spring, the linear bearing and the hook opening push block can be driven. Because the locking device of each hopper has the condition of different tightness, the spring can play a role of buffering when the unlocking hook push block contacts the locking device of the hopper. If the bucket locking device is too tight, the hook opening push block moves backwards through the linear bearing; at the same time, the spring is pressed, the pushing cylinder pushes forwards, and the pushing force is increased until the bucket locking device is pushed away. In case of pushing out the unlocking bucket device, the spring needs to be contracted to the shortest stroke, and the cylinder pushing device cannot be influenced. When the bucket locking device is pushed open, the system starts the bucket opening motor again, but the bucket opening motor rotates clockwise at this time, and the bucket opening arm is rotated through the coupler until the bucket opening sensor is triggered; at the moment, the front end of the bucket opening arm just presses down the arm of the hopper, and the hopper opening is opened through the lever effect. If the excess material in the hopper falls down into a collecting container below. Meanwhile, the cylinder can be retracted until the cylinder retreats after being triggered, the bucket locking device on the hopper is put down, and the system can control the bucket opening time according to the setting; when the time reaches, the system starts the fighting motor and rotates anticlockwise until the origin sensor is triggered, so that the fighting arm leaves the arm of the hopper, and the opening of the hopper is naturally closed to wait for the next operation.

S09, when the operator presses the blanking key again, the system will press the steps S3-S7 again to operate.

S10, the hopper just at the No. 3 station rotates to the No. 4 station; after the station sensor 904 No. 4 senses the hopper, the lifting cylinder 801 can stably put down the hopper cover plate 804 and the spray head 805 under the guidance of the guide shaft 802, and the waterproof cotton below the hopper cover plate 804 can just press the hopper, so that the waterproof cotton can provide a good sealing effect to prevent water splash. When the lower reach sensor 808 is triggered, the system activates the high pressure water pump to the spray head 805 through the intake pipe interface 803. The spray head is provided with a plurality of nozzles with different angles, so that the sprayed water can be sprayed to different positions in the hopper. The system can spray clear water according to set time, and then the system sends a signal to control the bucket opening device to discharge sewage in the bucket to a sewage collecting position below for treatment. The bucket opening operation method is the same as that of the station No. 3; the bucket opening time is also operated according to the set time, when the time is up, a bucket closing signal is sent, the hook opening cylinder is pushed out, and the bucket locking device is pushed away according to the description of the station No. 3; then the bucket opening motor rotates anticlockwise, and the bucket opening arm is rotated through the coupler until the bucket closing sensor is triggered. At the moment, the hook opening cylinder retreats until the sensor bucket locking device is triggered to fall down, arms of the hopper are hooked together, and finally the motor is started again to rotate clockwise to return to a zero position. Thus, the whole cleaning process is completed, and the feeding is waited to be transferred back to the No. 1 station for feeding.

S11, when the cleaning is finished, all mechanisms of the No. 4 station return to respective original points; when all signals are in place, the blocking shaft is retracted, the electromagnetic valve corresponding to the hydraulic motor acts to enable the hydraulic motor to rotate, and the cleaned clean empty hopper is carried to rotate to the No. 1 station to wait for reuse.

And S12, finishing the whole process of the automatic cleaning system after the steps are finished smoothly.
