Examples

Referring to fig. 1, the present embodiment provides a wall whitewashing apparatus 1000. The wall plastering device 100 of the wall plastering equipment 1000 comprises a first cylinder 110 and a first feeding assembly, wherein the feeding direction of the first feeding assembly is arranged along the axial direction of the first cylinder 110, the side wall of the first cylinder 110 is provided with a discharge hole 111, and the discharge hole 111 extends along the axial direction of the first cylinder 110.

In use, the slurry moves in the axial direction of the first cylinder 110 under the conveying force of the first feed assembly. Since the discharge port 111 is disposed at the side wall of the first cylinder 110 and extends in the axial direction of the first cylinder 110, the axial force provided by the first feeding assembly is converted into the radial force during the slurry output from the discharge port 111. Since the feeding direction of the first feeding assembly is arranged along the axial direction of the first cylinder 110, the first feeding assembly has a large conveying length, which facilitates sufficient conveyance of the slurry and provides sufficient internal pressure. Under the effect of first feeding subassembly, thick liquids are fully diffused in first barrel 110 and finally are exported from discharge gate 111, because discharge gate 111 is also along the axial setting of first barrel 110, axial effort is fully turned into radial force, can guarantee like this that the ejection of compact speed of each position of discharge gate 111 is unanimous basically and can realize synchronous ejection of compact. In addition, because the axial force is converted into the radial force, the slurry is fully mixed in the first cylinder 110, the problem of explosive ejection of the slurry at the discharge port 111 can be avoided, and the controllability of slurry conveying and painting is greatly improved.

Through the improvement, the uniformity and the flatness of the plastering layer in the plastering process can be obviously improved, and the plastering equipment 1000 is more controllable. Generally, the wall plastering equipment 1000 has a simple structure, is easy to operate and use, can improve the uniformity and the flatness of a plastering layer in a wall plastering process, improves the quality of the plastering layer, contributes to improving the efficiency of wall plastering work, reduces the workload, and saves time cost and labor cost.

Specifically, referring to fig. 1 to 4, in the present embodiment, the whitewashing apparatus 1000 includes a base 300 and a lifting platform 400. The base 300 is provided with a guide rail disposed in a height direction, and the elevating platform 400 is slidably fitted to the guide rail. The plastering apparatus 100 is provided on the elevating platform 400. The base 300 is provided with a traveling mechanism 310 (specifically, a traveling wheel in the present embodiment), the guide rail includes a first slide rail 320 and a second slide rail 330 which are arranged in parallel, and the first slide rail 320 is provided with a rack 321. The lift table 400 is slidably fitted to the first slide rail 320 and the second slide rail 330, the lift table 400 is provided with a gear 410 for fitting with the rack 321, and the gear 410 is selectively driven by a driving device 420 (specifically, a servo motor equipped with a reducer in the present embodiment) provided to the lift table 400.

Note that, the above "selectively driving" means: when the gear 410 is required to rotate, the driving device 420 can be controlled to drive the gear; and when the gear 410 needs to be stopped, the driving device 420 can be controlled to stop.

The driving device 420 is used to drive the gear 410, so that the gear 410 and the rack 321 of the first slide rail 320 can move relatively, and the lifting platform 400 is driven to slide along the first slide rail 320 and the second slide rail 330, thereby achieving the purpose of lifting the lifting platform 400.

In this embodiment, the feeding device 200 and the whitewashing device 100 of the whitewashing apparatus 1000 are both disposed on the top of the lifting platform 400, and the axial line of the first cylinder 110 of the whitewashing device 100 is disposed along the horizontal direction.

In the process of plastering walls, the position of the plastering equipment 1000 is adjusted by the traveling mechanism 310 of the base 300, and the height of the plastering device 100 is adjusted by the lifting table 400, so that continuous plastering operation can be realized.

In other embodiments of the present invention, a control system (e.g., PLC) may be further coupled to the whitewashing apparatus 100, and the control system is used to control the movement of the traveling mechanism 310 of the base 300, the lifting operation of the lifting platform 400, and the discharging operation of the whitewashing apparatus 100.

When the whitewashing device 100 is moved to a designated position, the control system controls the whitewashing device 100 to start discharging, and controls the lifting of the lifting platform 400 by controlling the opening/closing and the rotating direction of the driving device 420, thereby completing the whitewashing work in a height direction. After the wall surface is painted, the control system controls the traveling mechanism 310 to travel a distance of the length of the discharge port 111 along the wall, and then the next wall painting operation in the height direction can be performed. And the operation is repeated in sequence, so that the painting work of the whole wall surface can be completed.

The existing wall whitewashing equipment 1000 has high dependence on workers in the using process, high physical consumption on operators, obvious fatigue feeling after long-time work, high labor cost and the like, and is not beneficial to improving efficiency.

Returning to the embodiment, the tops of the first slide rail 320 and the second slide rail 330 may further be provided with a reinforcing rib connecting the two, so as to improve the stability of the first slide rail 320 and the second slide rail 330, thereby ensuring that the lifting platform 400 is more stable in the operation process and improving the quality of the whitewashed wall.

Further, please refer to fig. 5 to 7, an inner cavity of the first cylinder 110 is cylindrical, the first feeding assembly includes a first spiral conveying shaft 120, and an outer diameter of the first spiral conveying shaft 120 is smaller than an inner diameter of the first cylinder 110. Specifically, the ratio of the outer diameter of the first conveying screw 120 to the inner diameter of the first cylinder 110 is 5.7 to 6.2: 7. in the present embodiment, the ratio of the outer diameter of the first conveying screw 120 to the inner diameter of the first cylinder 110 is 6.1: 7. the inventor in the research process unexpectedly finds that when the ratio of the outer diameter of the first spiral conveying shaft 120 to the inner diameter of the first cylinder 110 is controlled to be 5.7-6.2: 7', the extrusion effect of the slurry is very good, and the extrusion speed is controlled to be 6.1: the effect is close to the best at 7. When the extrusion temperature is beyond the range, the extrusion effect of the slurry is obviously reduced, but the extrusion temperature is obviously better than the wall plastering effect of the traditional wall plastering machine.

It should be noted that the "outer diameter of the first conveying screw shaft 120" refers to the maximum outer diameter of the spiral blade of the first conveying screw shaft 120 in the radial direction.

In the above structure, the gap between the first conveying screw 120 and the first cylinder 110 provides an effective space for the extension of the slurry and allows the slurry to flow across the helical blades, which greatly improves the filling degree of the slurry in the first cylinder 110 and ensures that the slurry is filled in the whole first cylinder 110. Meanwhile, such a structure is also advantageous in that the internal pressure distribution inside the slurry is more uniform, and the axial conveying force of the first conveying screw 120 is converted into the internal pressure for sending out the slurry (finally, the internal pressure is expressed as a radial force), which contributes to the homogenization of the internal pressure, and thus the uniform and stable output of the slurry from the discharge port 111 is promoted.

The first cylinder 110 has an arc-shaped sidewall 112, the arc-shaped sidewall 112 is parallel to the central axis of the first cylinder 110, and the discharge port 111 is opened on the arc-shaped sidewall 112. The structural arrangement can avoid the damage of the wall surface of the first cylinder 110 to the painting layer. In this embodiment, the first cylinder 110 is cylindrical, and the discharge port 111 is opened in a side wall of the first cylinder 110 and extends in an axial direction thereof.

Both sides of discharge gate 111 all are provided with rib 113, and rib 113 sets up and extends along the axial of first barrel 110 along the edge of discharge gate 111. The side wall of one side of the two ribs 113 far away from the discharge port 111 is a finishing wall 113a, and the finishing walls 113a of the two ribs 113 are located on the same plane and are both perpendicular to the discharge direction of the discharge port 111. The finishing wall 113a serves to further level the whitewash layer. The ribs 113 are arranged at the edge of the discharge hole 111, so that the plastering layer can be leveled in the first time, and the quick-drying type slurry can play a good role in using.

Further, referring to fig. 8, the feeding device 200 of the whitewall apparatus 1000 includes: a second barrel 210 and a second feed assembly. The discharge end of the second cylinder 210 is communicated with the feed end of the first cylinder 110 through a feed pipe 230, and the second feed assembly is arranged on the second cylinder 210 and used for conveying the slurry in the second cylinder 210 to the first cylinder 110.

In this embodiment, the second cylinder 210 is cylindrical, the inner cavity of the second cylinder 210 is also cylindrical, the second feeding assembly includes a second spiral conveying shaft 220, the second spiral conveying shaft 220 is axially disposed along the second cylinder 210, the outer diameter of the second spiral conveying shaft 220 is smaller than the inner diameter of the second cylinder 210, and the feeding end of the second cylinder 210 is provided with a feeding hopper 211. One end of the feed pipe 230 is connected to the end wall of the discharge end of the second cylinder 210, and the other end is connected to the end wall of the feed end of the first cylinder 110.

The whitewashing device 100 and the feeding device 200 are both mounted on the lifting platform 400, and the first spiral conveying shaft 120 of the whitewashing device 100 and the second spiral conveying shaft 220 of the feeding device 200 are both driven by a driver 240 (a driving motor in this embodiment) through a synchronous belt 250, so as to ensure the synchronism of the operation of the two. Of course, the driving method is not limited thereto.

To sum up, whitewashing equipment 1000 simple structure, easily operation and use can improve whitewashing layer's in-process whitewashing degree of consistency and roughness, improves whitewashing layer quality, helps improving the efficiency of whitewashing work to reduce work load, save time cost and human cost.
