[0022] To make the purpose, technical solutions, and advantages of the embodiments of this application more clear, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0023] according to Figure 1 、 2 As shown in Figures 3 and 4, a plaster layer surface leveling device is proposed in this embodiment, including a transmission box 1, two sets of plastering disks 2 are provided on one side of the transmission box 1, the plastering disks 2 are rotatably connected to the transmission box 1, a transmission shaft 14 is rotatably provided in the transmission box 1, and transmission components for driving the two plastering disks 2 to rotate synchronously are provided at both ends of the transmission shaft 14;

[0024] A first bracket 3 is fixedly connected to the top of the transmission box 1. A rotating shaft 4 is rotatably provided on the top of the first bracket 3. A plurality of plastering rollers 5 are sleeved on the outer side of the rotating shaft 4.

[0025] An open slot 8 is provided on the top of the transmission box 1, and a belt transmission member is provided in the open slot 8. The rotating shaft 4 is rotatably connected to the transmission shaft 14 through the belt transmission member. A driving component for controlling the rotation of the transmission shaft 14 is provided on the side of the transmission box 1 away from the plastering disk 2.

[0026] The driving assembly controls the rotation of the transmission shaft 14. During the rotation of the transmission shaft 14, the two plastering disks 2 are driven to rotate synchronously through the transmission assembly to spread the mortar evenly. While spreading the mortar evenly, the transmission shaft 14 will drive the plastering roller 5 on the top of the transmission box 1 to rotate synchronously through the belt transmission member. The plastering roller 5 spreads the mortar twice during rotation. The rotation direction of the plastering disk 2 is different from that of the plastering roller 5. Therefore, during the leveling process, the surface texture of the exterior wall plaster layer can be effectively removed, and the surface quality of the plaster layer can be improved.

[0027] It's worth noting that two sets of third brackets 15 are fixedly mounted inside the transmission case 1. These brackets 15 fit over the outside of the transmission shaft 14, and the transmission shaft 14 is rotatably connected to the third brackets 15. The third brackets 15, mounted inside the transmission case 1, support the transmission shaft 14 and allow it to rotate within the transmission case 1. The third brackets 15 and transmission shaft 14 are connected via ball bearings.

[0028] About transmission components:

[0029] The transmission assembly includes two sets of main shafts 12, two sets of first bevel gears 13, and two sets of second bevel gears 18. The main shaft 12 is rotatably connected to the inside of the transmission box 1. The two sets of main shafts 12 are respectively fixedly connected to the two sets of plastering disks 2. The first bevel gear 13 is sleeved on the outside of the main shaft 12. The main shaft 12 and the first bevel gear 13 are fixedly connected. The second bevel gear 18 is fixedly connected to the left and right ends of the transmission shaft 14. The first bevel gear 13 meshes with the second bevel gear 18. When the transmission shaft 14 rotates, the second bevel gears 18 fixed to the left and right ends of the transmission shaft 14 will also rotate. During the rotation of the second bevel gear 18, it meshes with the first bevel gear 13, thereby driving the two sets of first bevel gears 13 to rotate synchronously. During the rotation of the first bevel gear 13, the plastering disk 2 is driven to rotate through the main shaft 12 to smooth the wall surface.

[0030] About the driver components:

[0031] The drive assembly includes a motor 9, the mounting end of which is fixedly connected to the outside of the transmission box 1. The output end of the motor 9 is fixedly connected to one set of main shafts 12. The motor 9 drives the main shafts 12 to rotate. The rotation of the main shafts 12 drives the other set of main shafts 12 through the transmission shaft 14 and the bevel gear transmission, thus achieving synchronous control of the two sets of plastering plates 2.

[0032] When the transmission shaft 14 rotates, the transmission shaft 14 will drive the rotating shaft 4 to rotate synchronously through the belt transmission part. Specifically, the belt transmission part includes two sets of pulleys 16, and the two sets of pulleys 16 are respectively arranged on the outside of the rotating shaft 4 and the transmission shaft 14. The rotating shaft 4 and the transmission shaft 14 are respectively fixedly connected to the two sets of pulleys 16, and the two sets of pulleys 16 are connected through the transmission belt 7.

[0033] When the transmission shaft 14 rotates, it will drive the pulley 16 to rotate. During the rotation of the pulley 16, the transmission belt 7 drives another set of pulleys 16 to rotate, and the rotating shaft 4 fixed to the pulley 16 will also rotate, completing the synchronous drive of the plastering roller 5 and the plastering disk 2.

[0034] To prevent mortar from falling through the opening 8 into the transmission box 1 or from adhering to the outside of the transmission belt 7 and affecting the operation of the belt transmission parts and the transmission assembly, in a preferred embodiment, a dust shield 11 is provided on the top of the transmission box 1. The dust shield 11 is provided on the outside of the belt transmission parts. A fixing bolt 17 is threadedly connected to the edge of the dust shield 11, and the fixing bolt 17 is threadedly connected to a bolt hole provided in the top of the transmission box 1. When removing the dust shield 11 from the top of the transmission box 1, the fixing bolt 17 can be unscrewed from the bolt hole in the top of the transmission box 1.

[0035] To improve the efficiency of the leveling device, in a preferred embodiment, a plurality of second brackets 10 are provided on the side of the transmission box 1 away from the plastering plate 2. The second brackets 10 are fixedly connected to the transmission box 1 and have a plurality of bolt holes. The transmission box 1 can be fixed to the lifting bracket of the external vehicle body through the second brackets 10 and the bolts, thereby improving leveling efficiency.

[0036] How this application works:

[0037] The driving assembly controls the rotation of the transmission shaft 14. During the rotation of the transmission shaft 14, the two plastering disks 2 are driven to rotate synchronously through the transmission assembly to spread the mortar evenly. While spreading the mortar evenly, the transmission shaft 14 will drive the plastering roller 5 on the top of the transmission box 1 to rotate synchronously through the belt transmission member. The plastering roller 5 spreads the mortar twice during rotation. The rotation direction of the plastering disk 2 is different from that of the plastering roller 5. Therefore, during the leveling process, the surface texture of the exterior wall plaster layer can be effectively removed, and the surface quality of the plaster layer can be improved.
