DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1: This embodiment is intended to help solve the problem that since shield mortar mixers are usually used on construction sites, there will be a large amount of mortar residue inside them, and the mortar residue may adhere to the surfaces of various components, so it takes a lot of time and effort to clean them thoroughly. Please refer to Figure 1 - Figure 5 A shield mortar mixing and stirring device comprises a workbench 100, a support frame 200, a motor 300 and a mixing drum 400, the support frame 200 is mounted at the bottom of the workbench 100, the mixing drum 400 is mounted at the bottom of the workbench 100, a lower barrel 410 is plugged into the side of the mixing drum 400, a loading port 110 is opened on both the workbench 100 and the mixing drum 400, the motor 300 is arranged at the side of the mixing drum 400, a driving wheel 310 is mounted on the side of the motor 300, a driving wheel 420 is plugged into the side of the mixing drum 400, the driving wheel 310 and the driving wheel 420 are connected to each other by a belt 320, a rotating rod 430 is plugged into the mixing drum 400, an end of the rotating rod 430 passes through the mixing drum 400 and is connected to the driving wheel 420, a plurality of mixing blades 440 are mounted outside the rotating rod 430, and a cleaning component 500 is arranged inside the mixing blades 440.

[0024] The cleaning assembly 500 includes a push sleeve 510 installed on the side of the driving wheel 420 close to the mixing drum 400, the push sleeve 510 is inserted into the mixing drum 400, and a push rod 520 corresponding to the mixing blade 440 is installed outside the mixing drum 400, and the push rod 520 is inserted into the mixing blade 440. The cleaning assembly 500 also includes a control chamber 530 opened in the mixing blade 440, the push rod 520 is inserted in the control chamber 530, the mixing blade 440 is opened with a through opening 540, a blocking plate 541 is installed in the through opening 540, a telescopic rod 542 is installed between the blocking plate 541 and the push rod 520, and a first spring 543 is provided on the outer sleeve of the telescopic rod 542.

[0025] A groove 550 is provided in the push rod 520, a cleaning plate 560 is installed in the groove 550, a plurality of limiting holes 561 are provided on the cleaning plate 560, a cleaning brush 562 is installed in the limiting holes 561, a push rod 563 is installed at the bottom of the cleaning brush 562, the push rod 563 is located in the control chamber 530 through the push rod 520, and a top plate 570 is installed at the bottom of the push rod 563.

[0026] A receiving block 580 corresponding to the top plate 570 is installed in the control chamber 530, a first inclined surface 571 is provided on the top plate 570, and a second inclined surface 581 is provided on the receiving block 580. When cleaning, the push rod 520 is pushed, and the top plate 570 passes through the first inclined surface 571 and the second inclined surface 581, so that the top plate 570 is located on the receiving block 580. A second spring 564 is provided on the outer sleeve of the top rod 563, one end of the second spring 564 contacts the cleaning plate 560, and the other end of the second spring 564 contacts the top plate 570.

[0027] When cleaning the mixing drum 400, the operator turns off the motor 300, pushes the push sleeve 510 and the push rod 520, and as the push rod 520 is pushed, the telescopic rod 542 is first driven to make the blocking plate 541 open the through hole 540. At this time, the push rod 520 is pushed forward again, and the first inclined surface 571 on the top plate 570 moves to the receiving block 580 through the second inclined surface 581. Since the top plate 570 is located on the receiving block 580, and the receiving block 580 has a certain height, the top plate 570 drives the top rod 563 to apply force to the cleaning plate 560, so that the cleaning plate is released from the groove 550 and connected to the through hole 540. At this time, the motor 300 is turned on, and the motor 300 rotates the driving wheel 310, and drives the driving wheel 420 through the belt 320. The rotation of the driving wheel 420 causes the mixing blade 440, the cleaning brush 562 and the rotating rod 430 to rotate together, and the mixing drum 400 begins to be cleaned.

[0028] When the cleaning is finished, the operator needs to turn off the motor 300, stop the rotation of the stirring blade 440, the cleaning brush 562 and the rotating rod 430, and then the operator will continue to pull the push rod 520 so that the cleaning assembly 500 begins to be recovered. The movement of the push rod 520 will cause the cleaning plate 560 to be released from the through port 540 and re-engaged in the groove 550. The continued pulling of the push rod 520 will cause the push sleeve 510 to gradually withdraw from the mixing drum 400 until it is completely recovered to its original position. This step ensures that the cleaning assembly 500 is completely withdrawn from the mixing drum 400. In the process of pushing the sleeve 510 to be recovered, the telescopic rod 542 will adjust the position of the baffle plate 541 and close the through port 540 to ensure the safe recovery of the cleaning brush 562 and the cleaning plate 560. Once the cleaning assembly 500 is completely recovered to its original position, the operator can check the cleaning assembly 500 to ensure that all components are in normal position and ready for the next cleaning or normal operation.

[0029] In this embodiment: through the design of the cleaning component 500, especially the arrangement of components such as the cleaning plate 560, the cleaning brush 562 and the pushing sleeve 510, the thorough cleaning of the inner wall of the mixing drum 400 is ensured, and the automated design of the cleaning process not only improves the cleaning efficiency but also reduces the workload of the operator. At the same time, when the cleaning component 500 is recovered, it can also ensure that the cleaning component 500 is safely and effectively withdrawn from the mixing drum 400 to prepare for the next cleaning or normal operation, thereby improving the cleaning efficiency and reducing the consumption of human resources.

[0030] Embodiment 2: This embodiment is intended to further solve the problem of re-cleaning or failure caused by residue affecting the position of the cleaning component 500. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1 - Figure 5 .

[0031] A recovery groove 441 for recovering the baffle plate 541 is provided on the inner wall of the stirring blade 440 , and a slide groove 442 corresponding to the telescopic rod 542 is provided on the inner wall of the stirring blade 440 , and the telescopic rod 542 is slidably installed in the slide groove 442 .

[0032] A protective shell 330 is provided outside the driving wheel 310 and the driving wheel 420, and a control ring 340 for controlling the pushing sleeve 510 is installed on the protective shell 330, which can protect these components from potential physical damage and mortar corrosion at the construction site, extend the service life of the equipment, and reduce maintenance costs. At the same time, the control ring 340 installed on the protective shell 330 provides a more intuitive and convenient way to control the pushing sleeve 510, so that the operator can more easily perform the pushing and retrieving operations of the cleaning component 500, which not only reduces the labor intensity of the operator, but also reduces the possible errors in the operation process.

[0033] In the present embodiment: a recovery groove 441 for recovering the baffle plate 541 is opened on the inner wall of the stirring blade 440, and a slide groove 442 corresponding to the telescopic rod 542 is opened on the inner wall of the stirring blade 440. The telescopic rod 542 is slidably installed in the slide groove 442, so that the movement of the telescopic rod 542 and the baffle plate 541 can be more effectively guided to ensure that they can be smoothly and completely recovered to their original positions after the cleaning process, thereby reducing the need for re-cleaning or malfunctions caused by residues affecting the position of the cleaning component 500.
