Many modifications and variations will be apparent to those skilled in the art. The embodiments are chosen and described to better illustrate the principles of the invention and its practical application, and to enable those skilled in the art to understand the invention and design various embodiments with various modifications as appropriate for specific applications.

[0031] A wall plasterboard positioning mobile device, such as Figure 2 、 Figure 3 、 Figure 4As shown, it includes a plasterboard body 1, and a collecting mechanism for collecting fallen soil and dust is arranged below the plasterboard body 1. The collecting mechanism includes a guide plate 2, a frame 201, a conveyor 202 and a storage box 203. The plasterboard body 1 is located in the frame 201, and the guide plate 2 is slidably connected to the opposite inner wall of the frame 201. The conveyor 202 is located below the guide plate 2, and the storage box 203 is arranged below the conveyor 202. An adjustment component for changing the angle between the plasterboard body 1 and the wall is provided between the frame 201 and the plasterboard body 1, and a scraping component for taking materials is provided in the storage box 203.

[0032] When plastering, the adhesion between the dust and the wall is sometimes not very strong, or too much dust gathers at the same time, which may cause some of the dust to fall off. The fallen dust can be collected by the provided collection mechanism to avoid waste of materials and ground pollution. Specifically, the fallen dust is guided to the surface of the conveyor 202 by the guide plate 2, and then the conveyor 202 is started to transport the dust to the storage box 203 below, thereby completing the collection of the dust. The collected dust can be reused, which further saves materials and prevents the dust from falling to the ground and causing ground pollution.

[0033] like Figure 4 、 Figure 5 As shown, the adjustment assembly includes a first hydraulic cylinder 3, a slide 301, a push rod 302, a connecting plate 303, a transmission plate 304 and a first mounting rod 305. The first hydraulic cylinder 3 is installed on the surface of the connecting plate 303. A slide groove is provided on the upper end surface of the frame 201. The connecting plate 303 is slidably connected in the slide groove of the frame 201. The slide 301 is fixedly connected to the surface of the connecting plate 303 symmetrically on the left and right. The push rod 302 is slidably connected in the slide 301. The end of the push rod 302 extends to the outside of the slide 301 and is rotatably connected to the plastering board body 1. The transmission plate 304 is fixedly connected to the push rod 302. A rectangular groove is provided on the opposite side of the slide 301. The transmission plate 304 is slidably set in the rectangular groove. The telescopic end of the first hydraulic cylinder 3 is fixedly connected to the transmission plate 304.

[0034] During plastering, if the wall and the ground are not perpendicular, such as on stairs, the angle between the plastering board body 1 and the wall can be adjusted by the provided adjustment component. The specific steps are to start the first hydraulic cylinder 3 to drive the transmission plate 304 to move, the transmission plate 304 drives the push rod 302 to move, and the push rod 302 finally pushes the plastering board body 1 connected thereto to rotate until it is parallel to the wall. Through the above technical solution, the scope of application of the present device is increased.

[0035] like Figure 2 、 Figure 4As shown, a reciprocating moving component is arranged between the frame 201 and the plastering board body 1, and the reciprocating moving component includes a first motor 4, a screw rod 401, a sliding frame 402 and a slide rail 403. The first motor 4 is installed on the surface of the frame 201, and the output end of the first motor 4 is fixedly connected to the screw rod 401. The sliding frame 402 is slidably connected to the bottom of the frame 201. The first mounting rod 305 is fixedly connected to the surface of the sliding frame 402.

The slide rail 403 is fixedly set at the bottom of the frame 201, and the sliding frame 402 is slidably connected to the slide rail 403.

[0036] The reciprocating moving component is used to drive the plastering board body 1 to move back and forth, thereby realizing the plastering operation on the wall. Specifically, the first motor 4 is started to drive the screw rod 401 fixedly connected to it, and the screw rod 401 further drives the first mounting rod 305 threadedly connected to it, and the plastering board body rotatably connected to the first mounting rod 305 moves synchronously. Since the first mounting rod 305 is fixedly connected to the sliding frame 402, the sliding frame 402 drives the plastering board body 1 and the first mounting rod 305 to move back and forth in a straight line under the limit of the slide rail 403.

[0037] like Figure 4 、 Figure 5 As shown, the storage box 203 is provided with a rotating assembly for facilitating unloading, and the rotating assembly includes a sealing plate 5, a limiting plate 501 and an insertion rod 502. The sealing plate 5 is rotatably connected to the inner wall of the storage box 203, and the limiting plate 501 is fixedly connected to the outer wall of the storage box 203. The limiting plate 501 is L-shaped, and the insertion rod 502 is inserted between the sealing plate 5 and the storage box 203, and the insertion rod 502 cooperates with the limiting plate 501.

[0038] Before the soil ash in the storage box 203 needs to be unloaded and reused, the sealing plate 5 is rotated to a certain angle using the rotating assembly so that the sealing plate 5 will not block the unloading during unloading. The specific steps are to first pull the insertion rod 502 to extract the insertion rod 502 from the storage box 203, and then rotate the sealing plate 5 until the insertion rod 502 is located above the limit plate 501, and then push the insertion rod 502 until the insertion rod 502 moves above the limit plate 501, and finally place the insertion rod 502 on the surface of the limit plate 501, and the limit plate 501 can support the sealing plate 5, thereby facilitating the unloading of the soil ash in the storage box 203.

[0039] like Figure 10 As shown, a sliding groove 503 is provided on the surface of the sealing plate 5, and a shift rod is fixedly connected to the surface of the insertion rod 502. The insertion rod 502 and the sliding groove 503 are slidably connected, and the shift rod extends to the outside of the sealing plate 5. The shift rod is provided to facilitate pulling the insertion rod 502.

[0040] like Figure 5 、 Figure 6 and Figure 8 As shown, the scraper assembly includes a hollow box 6, a slide 601, a second spring 602, a rotating shaft 603, a second motor 604, a bevel gear set 605, a driving gear 606 and a rack 607. The hollow box 6 is slidably connected to the surface of the storage box 203, the slide 601 is slidably connected to the inside of the hollow box 6, the slide 601 is slidably connected to the bottom of the storage box 203, the second spring 602 is arranged inside the hollow box 6 and is fixedly connected to the slide 601, the rotating shaft 603 is rotatably connected to the hollow box 6, the second motor 604 is installed inside the hollow box 6, one of the bevel gears in the bevel gear set 605 is fixedly connected to the output end of the second motor 604, and the other bevel gear is fixedly connected to the outer wall of the rotating shaft 603, the two bevel gears are meshed, the driving gear 606 is fixedly connected to the end of the rotating shaft 603, and the rack 607 is arranged inside the storage box 203 and meshes with the driving gear 606.

[0041] Since the conveyor 202 only gathers in a small area of ​​the storage box 203 when conveying the dust to the storage box 203, the dust gathered is dispersed to various areas of the storage box 203 by the provided scraper assembly, thereby expanding the loading capacity of the storage box 203. In addition, when the dust needs to be unloaded from the storage box 203, the provided scraper assembly can also be used to achieve this. Specifically, the second motor 604 is started to drive a bevel gear fixedly connected to the output end of the second motor 604 to rotate, and the output end of the second motor 604 is connected to the bevel gear. The fixedly connected bevel gear drives another bevel gear meshing with it to rotate, and the other bevel gear drives the rotating shaft 603 fixedly connected to it to rotate, and the rotating shaft 603 further drives the driving gear 606 fixedly connected to it to rotate. Under the action of the rack 607, the driving gear 606 drives the rotating shaft 603, the hollow box 6 and the slide 601 to move, and the slide 601 and the hollow box 6 push the soil ash in the storage box 203 to move, thereby evenly dispersing the gathered soil ash in the storage box 203 or removing the soil ash from the storage box 203.

[0042] like Figure 2 、 Figure 5 As shown, a lifting assembly is provided between the frame 201 and the storage box 203, and the lifting assembly includes an electric telescopic rod 7, a connecting frame 701 and a push plate 702. The electric telescopic rod 7 is installed at the bottom of the frame 201, and the telescopic end of the electric telescopic rod 7 is fixedly connected to the connecting frame 701. The connecting frame 701 is slidingly connected to the storage box 203, and the push plate 702 is slidingly connected to the bottom of the storage box 203. The connecting frame 701 and the push plate 702 are fixedly connected, and the push plate 702 cooperates with the slide plate 601.

[0043] The lifting assembly is used to lift the slide 601, so as to prevent the slide 601 from blocking the expansion of the soil ash in the storage box 203. By starting the electric telescopic rod 7, the connecting frame 701 is driven to move, and the connecting frame 701 further drives the push plate 702 to move, and the push plate 702 finally pushes the slide 601 to move.

[0044] like Figure 4 As shown, the surface of the conveyor 202 is evenly provided with baffles 204, which can pre-divide the dust falling from the guide plate 2 to prevent the dust from piling up too much and being difficult to flatten in the storage box 203 when it falls. The conveyor 202 and the sliding frame 402 are fixedly connected by a fan-shaped plate, which further blocks the dust on the conveyor 202 from falling. The storage box 203 and the sliding frame 402 are fixedly connected, and the outer wall of the guide plate 2 is fixedly connected with a connecting shaft 2 05, the connecting shaft 205 passes through the frame 201 and is rotatably connected to the connecting ring 207, the surface of the frame 201 is fixedly connected to the fixing seat 208, and the first spring 206 is fixedly connected between the connecting ring 207 and the fixing seat 208. The provided connecting ring 207, the fixing seat 208 and the first spring 206 can support the guide plate 2, and at the same time, the connecting shaft 205 rotates in the connecting ring 207 as the guide plate 2 moves, so that the first spring 206 will not be twisted.

[0045] like Figure 1 As shown, a mounting frame 9 is provided below the frame 201, and a lifting assembly is provided between the frame 201 and the mounting frame 9. The lifting assembly includes a lifting frame 8, a second hydraulic cylinder 801 and a second mounting rod 802. The lifting frame 8 is provided with two groups, each group of the lifting frame 8 is composed of two connecting rods that are rotatably connected to each other, and each group of connecting rods is connected in an X shape. A strip slide is provided at the bottom of the mounting frame 9, and one of the connecting rods in each group of connecting rods is rotatably installed in the strip slide, and the other is slidably connected to the strip slide. In the figure, a rectangular slide corresponding to the strip slide at the bottom of the mounting frame 9 is opened at the bottom of the frame 201, and each group of connecting rods is respectively rotatably installed and slidably connected to the rectangular slide. A reinforcing rod is fixedly connected between the two groups of lifting frames 8. The second hydraulic cylinder 801 is installed on the mounting frame 9, and the second mounting rod 802 is rotatably connected to the center of the two groups of lifting frames 8. The telescopic end of the second hydraulic cylinder 801 is fixedly connected to the second mounting rod 802, and universal wheels 10 are installed at the four corners of the bottom of the mounting frame 9.

[0046] When lifting is required, the second hydraulic cylinder 801 is started to drive the connecting rod in the lifting frame 8 to move, and the movement of the connecting rod drives the two groups of lifting frames 8 to rotate. The connecting rod in the lifting frame 8 rotates to push the frame 201 to lift and lower. When the angle between each group of connecting rods in the lifting frame 8 becomes smaller, the frame 201 rises, and when the angle becomes larger, the frame 201 falls, so that walls of different heights can be plastered.
