Description

Technical Field

[0001] This utility model relates to the field of building construction equipment, and more specifically, to a wall plastering machine. Background Technology

[0002] Wall plastering refers to the application of cement mortar, mixed mortar, and lime mortar to walls. Interior and exterior wall plastering is a task performed after the completion of building structure construction. Scientific plastering can provide moisture protection, weathering prevention, and heat insulation, preventing the building walls from being eroded by wind, rain, and snow. While cement walls constructed with large formwork are smooth and flat, plastering is necessary to straighten the walls at intersections of longitudinal and transverse walls, between upper and lower floors in stairwells, and around door and window openings.

[0003] Patent application number 202323005503.1 discloses a wall plastering machine, including a base frame. A base is bolted to the surface of the base frame. A support rod is located on the top of the base. Both the base and the top of the support rod are inlaid with internal threaded seats. A first screw is fixedly connected to the bottom of the support rod. The bottom of the first screw is connected to the internal threaded seat via a threaded connection. A movable platform is located on the top of the base frame and is sleeved on the outside of the support rod. A tray is fixedly connected to the surface of the base frame, and a battery is located on the top of the tray. This utility model, by setting a detachable support rod, with an internal threaded seat inlaid on the top of the support rod and a first screw fixedly connected to the bottom of the support rod, and the base bolted to the surface of the base frame, with an internal threaded seat also inlaid on the top of the base, allows the machine to be disassembled simply by rotating the support rod when not in use. This reduces the space occupied by the wall plastering machine and facilitates storage.

[0004] Regarding the aforementioned technologies, a scraper is installed inside the back plate, and a groove is opened on the surface of the back plate. A sliding strip is fixedly connected to the surface of the scraper and slides inside the groove. A mounting plate is fixedly connected to the top of the scraper, and the back plate is connected to the inside of the mounting plate by bolts. In this way, when the scraper is worn out, the bolts can be unscrewed to remove and replace the scraper, which helps to maintain the plastering effect of the equipment. However, the equipment does not have a collection structure. When the equipment applies cement, some cement may fall to the ground, causing some waste of materials, which requires subsequent manual collection. Utility Model Content

[0005] To solve the above problems, this utility model provides a wall plastering machine, which adopts the following technical solution:

[0006] A wall plastering machine includes a base, with base plates at each of the four corners of the base bottom. Lifting components are provided between the top of the base plates and the bottom of the base. Two symmetrically distributed storage slots are opened at the bottom of the base, and a support and movement component is provided in each of the two storage slots. Two symmetrically distributed lifting modules are fixedly installed at the top of the base, and a storage frame is provided between the two lifting modules. A scraper is provided on one side of the storage frame, and a baffle is fixedly installed at the top of the scraper. Two symmetrically distributed telescopic rods are provided between the scraper and the opposite side of the storage frame. A conveying pipe is fixedly installed on the inner wall of the bottom of the storage frame, and a material conveying component is provided between the conveying pipe and the scraper. A mixing component is provided inside the storage frame.

[0007] A collection frame is provided on the side of the base near the scraper. A locking block is fixedly installed on the side of the collection frame near the base. Two symmetrically distributed stabilizing blocks are fixedly installed on the side of the collection frame near the base. A slot and groove matching the locking block and stabilizing block are opened on the side of the base near the collection frame. An installation block is fixedly installed on one side of the base. A movable groove is opened in the installation block. A fixing component is provided in the movable groove.

[0008] The lifting module includes two first support columns located at the top of the base. A second support column is slidably mounted on the top of each of the two first support columns. Movable grooves are opened on the inner sides of the first and second support columns. Support blocks are slidably mounted in the two movable grooves. The opposite side of the two support blocks is fixedly connected to the opposite side of the storage frame. A second push rod is fixedly mounted on the inner wall of the bottom end of the two movable grooves. The top ends of the two second push rods are fixedly connected to the bottom end of the support block on the same side. A first support block and a second support block are respectively installed on the side of the first and second support columns away from the storage frame on the same side. A first push rod is provided between the first support block and the second support block on the same side.

[0009] By adopting the above technical solution, when using this equipment, the operator places the collection frame on one side of the base, allowing the stabilizing blocks and latches installed on the side wall of the collection frame to engage with the grooves and slots opened on the side wall of the base. This effectively limits and fixes the collection frame. Furthermore, the fixing components on the side wall of the base further restrict the fixing latches, helping to maintain the stability of the collection frame and base assembly. The operator can move the equipment to the wall using the support and movement components. Once the equipment is moved to the application position, the support and movement components move to the storage slot on the same side, allowing the base plate to contact the ground, thus providing stable support for the equipment. A lifting component is provided between the base plate and the base itself, allowing for adjustment of the base plate height, facilitating placement of the equipment on uneven surfaces. The ground level helps maintain the equipment's balance. Cement is then placed in a storage box equipped with a mixing component to agitate the cement, ensuring good mixing quality. Two symmetrically distributed baffles at the top of the storage box help prevent cement splattering during mixing, reducing waste. A telescopic rod drives a scraper to contact the wall, and a conveying component guides the cement from the storage box between the scraper and the wall. Two lifting modules then drive the storage box and scraper to rise synchronously, applying the cement to the wall. Some cement may fall during application; a collection box collects this spilled cement, further minimizing waste.

[0010] Furthermore, the lifting assembly includes columns fixedly installed at the four corners of the bottom of the base. Each column has a screw groove at its bottom, and a screw rod is installed in each screw groove. The bottom end of the screw rod is connected to the top of the base plate of the same group, and a handle is fixedly sleeved on the lower side wall of each screw rod.

[0011] By adopting the above technical solution, the screw is driven to rotate by the handle. The screw rotates in the screw groove opened at the bottom of the same group of columns, thereby driving the lifting and lowering of the same group of base plates. This makes it easier to place the equipment on uneven ground and helps to maintain the balance of the equipment.

[0012] Furthermore, the supporting moving component includes mounting plates disposed in two storage slots. Two symmetrically distributed cylinders are fixedly installed on the inner walls of the top of each of the two storage slots. Connecting blocks are fixedly installed on the piston shaft ends of each cylinder. The bottom ends of the two connecting blocks on the same side are fixedly connected to the top of the mounting plate on the same side. Shock absorbers are provided at the four corners of the bottom of the two mounting plates. A first spring is sleeved on the side wall of each shock absorber. A drive wheel is connected to the bottom of each shock absorber.

[0013] By adopting the above technical solution, the mounting plate and drive wheel on the same side are lowered by the cylinder, so that the drive wheel contacts the ground and the base rises. Then the equipment can be moved by the drive wheel, which improves the convenience of moving the equipment. Furthermore, a shock absorber and a first spring are provided between the mounting plate and the drive wheel. The first spring absorbs the vibration force, and the shock absorber can counteract the rebound force of the first spring, thus playing a role in shock absorption and buffering, which helps to maintain the stability of the equipment movement.

[0014] Furthermore, the material conveying assembly includes a support rod rotatably mounted inside the conveying pipe, a spiral blade sleeved on the side wall of the support rod, an installation box fixedly mounted on the side of the storage frame away from the scraper, a second geared motor fixedly mounted inside the installation box, the end of the support rod away from the scraper passing through the storage frame and extending into the installation box, the end of the support rod passing through the installation box being fixedly connected to the end of the output shaft of the second geared motor, the end of the conveying pipe away from the installation box passing through the storage frame, a multi-port connector provided on the side of the scraper near the storage frame, the end of the multi-port connector away from the storage frame passing through the scraper, and a telescopic hose provided at the end of the multi-port connector opposite to the conveying pipe.

[0015] By adopting the above technical solution, the inner wall of the bottom end of the storage frame is inclined, and the feed port opened on the side wall of the conveying pipe facilitates the cement to enter the conveying pipe. Then, the second reduction motor drives the support rod to rotate, and the support rod drives the spiral blade to rotate. The extrusion force generated by the spiral blade makes the cement enter the telescopic hose from the port of the conveying pipe. Subsequently, the cement enters the space between the scraper and the wall through the multi-port connector, which facilitates the subsequent coating of the equipment.

[0016] Furthermore, the mixing assembly includes two rotating rods rotatably mounted inside the storage frame. Each of the two rotating rods has multiple sets of mixing plates arranged in a linear array on its sidewall. At least three mixing plates in the same set are arranged in a ring array on the sidewall of the same set of rotating rods. A first reduction motor is fixedly installed on the side of the storage frame away from the scraper. A drive wheel is fixedly sleeved on the sidewall of the output shaft of the first reduction motor. The ends of the two rotating rods near the first reduction motor pass through the storage frame. A driven wheel is fixedly sleeved on the sidewall of the end of the two rotating rods that passes through the storage frame. The drive wheel has two grooves. A belt is sleeved between the two driven wheels and the drive wheel.

[0017] By adopting the above technical solution, after the workers place the cement in the storage box, the first reduction motor drives the drive wheel to rotate. The drive wheel drives the driven wheel on the same side to rotate through two belts. The two driven wheel drives the rotating rod in the same group to rotate. The rotating rod drives the mixing plate in the same group to rotate. Through the cooperation of multiple mixing plates, the cement can be mixed and stirred, which helps to maintain the quality of the cement. In addition, two symmetrically distributed baffles are provided at the top of the storage box, which helps to prevent cement from splashing out during the mixing process and reduces material waste.

[0018] Furthermore, the fixing component includes a fixing block that is slidably installed in the movable groove. A second spring is fixedly connected between the inner wall of one side of the fixing block and the side opposite to the movable groove. The inner side of the fixing block away from the second spring contacts the side opposite to the locking block. A toggle rod is fixedly installed on the side of the fixing block away from the base. The toggle rod slides through the movable groove at the end away from the base.

[0019] By adopting the above technical solution, when the collection frame needs to be installed, the staff can slide the fixed block into the movable groove by pulling the lever. The fixed block pushes the second spring to retract, which makes it easier for the staff to move the locking block installed on the side wall of the collection frame into the locking groove opened on the side wall of the base. When the locking block and the locking groove are engaged, the staff releases the lever. Then, the fixed block returns to its original position under the elastic force of the second spring. The side of the fixed block near the base contacts the side opposite to the locking block, which plays a role in restricting and stabilizing the locking block and helps to prevent the locking block from falling out of the locking groove.

[0020] Furthermore, limit blocks are fixedly installed at the top and bottom of the section of the fixed block near the second spring, and limit grooves matching the limit blocks on the same side are opened on the inner walls of the top and bottom of the movable groove.

[0021] By adopting the above technical solution, when the fixed block slides in the movable groove, the fixed block, along with the limiting block, slides in the limiting groove on the same side. The cooperation between the limiting block and the limiting groove helps to maintain the stability of the fixed block's sliding and helps to prevent the fixed block from detaching from the movable groove.

[0022] In summary, this utility model has the following beneficial technical effects:

[0023] (1) In this utility model, the base sidewall is designed to collect cement that falls off the equipment during plastering by setting up a collection frame, which helps to reduce the material usage and facilitates subsequent processing by the staff. The collection frame can be installed by the engagement of the card block, card slot and stabilizing block and groove. Then, the card block is limited by the fixing component, which helps to prevent the card block and card slot from detaching and helps to maintain the stability of the collection frame installation.

[0024] (2) In this utility model, the mixing component is set to mix the materials inside the storage box, which helps to maintain the quality of cement mixing and facilitates subsequent coating of the equipment, thus helping to maintain the coating effect of the equipment.

[0025] (3) In this application, by setting up the lifting component, the screw driven by the handle rotates in the screw groove on the same side, thereby adjusting the height of the base plate, which facilitates the adjustment of the balance of the equipment placement, and thus helps to maintain the coating quality of the equipment.

[0043] The following is in conjunction with the appendix Figure 1-12 The present invention will be described in further detail below.

[0044] Please see Figure 1-12 A wall plastering machine includes a base 1. A collection frame 7 is provided on the side of the base 1 near the scraper 6. A locking block 17 is fixedly installed on the side of the collection frame 7 near the base 1. Two symmetrically distributed stabilizing blocks 16 are fixedly installed on the side of the collection frame 7 near the base 1. The side of the base 1 near the collection frame 7 has a slot 36 and a groove 35 that match the locking block 17 and the stabilizing block 16. An installation block 19 is fixedly installed on one side of the base 1. A movable groove 30 is provided in the installation block 19. A fixing component is provided in the movable groove 30. The fixing component includes a fixing block 18 that is slidably installed in the movable groove 30. A second spring 31 is fixedly connected between the inner wall of one side of the fixing block 18 and the side opposite to the movable groove 30. The inner side of the fixing block 18 away from the second spring 31 contacts the side opposite to the locking block 17. A toggle rod is fixedly installed on the side of the fixing block 18 away from the base 1. The toggle rod slides through the movable groove 30 at the end away from the base 1.

[0045] When the collection frame 7 needs to be installed, the operator pulls the fixing block 18 into the movable slot 30 by using the lever. The fixing block 18 pushes the second spring 31 to retract. Then, the operator can move the locking block 17 installed on the side wall of the collection frame 7 into the locking slot 36 opened on the side wall of the base 1. When the locking block 17 and the locking slot 36 are engaged, the operator releases the lever. Then, the fixing block 18 returns to its original position under the elastic force of the second spring 31, and the side of the fixing block 18 closest to the base 1 contacts the side opposite to the locking block 17, thus limiting and stabilizing the collection frame. The function of the retaining block 17 is to help prevent it from disengaging from the slot 36. Limiting blocks are fixedly installed at the top and bottom of the section of the fixed block 18 near the second spring 31. Limiting grooves matching the limiting blocks on the same side are formed on the inner walls of the top and bottom of the movable slot 30. When the fixed block 18 slides within the movable slot 30, it slides along with the limiting blocks within the limiting grooves on the same side. The cooperation between the limiting blocks and the limiting grooves helps maintain the stability of the fixed block 18's sliding motion and helps prevent it from disengaging from the movable slot 30.

[0046] The base 1 has base plates 10 at each of its four corners. Two symmetrically distributed storage slots 34 are formed at the bottom of the base 1. Each storage slot 34 contains a supporting moving assembly, which includes a mounting plate 13 within the slot. Two symmetrically distributed cylinders 15 are fixedly mounted on the inner walls of the top of each storage slot 34. Connecting blocks 14 are fixedly mounted on the piston shaft ends of each cylinder 15. The bottom ends of the two connecting blocks 14 on the same side are fixedly connected to the top of the mounting plate 13 on the same side. Shock absorbers 11 are provided at each of the four corners of the bottom of the two mounting plates 13. The side walls of the shock absorbers 11 are fitted with… The device has a first spring 12 and a shock absorber 11, both of which are connected to drive wheels at their bottom ends. The cylinder 15 drives the mounting plate 13 and the drive wheels on the same side to descend, making the drive wheels contact the ground and thus raising the base 1. The device can then be moved by the drive wheels, which improves the ease of moving the device. The mounting plate 13 and the drive wheels are equipped with shock absorbers 11 and the first spring 12. The first spring 12 absorbs the vibration force, and the shock absorbers 11 can counteract the rebound force of the first spring 12, thus playing a role in shock absorption and buffering, which helps to maintain the stability of the device movement.

[0047] A lifting assembly is provided between the top of the base plate 10 and the bottom of the base 1. The lifting assembly includes columns 8 fixedly installed at the four corners of the bottom of the base 1. Each column 8 has a screw groove at its bottom, and each screw groove has a screw 9. The bottom of the screw 9 is connected to the top of the base plate 10 of the same group. Each lower section of the screw 9 has a handle fixedly fitted on its side wall. When the equipment is moved to a suitable position, the cylinder 15 drives the mounting plate 13 and the drive wheel on the same side to rise and move into the storage slot 34 on the same side, so that the base plate 10 contacts the ground, which can play the role of supporting and stabilizing the equipment. The screw 9 can be driven to rotate by the handle. The screw 9 rotates in the screw groove at the bottom of the column 8 of the same group, which can drive the base plate 10 of the same group to rise and fall, which makes it easier to place the equipment on uneven ground and helps to maintain the balance of the equipment.

[0048] Two sets of symmetrically distributed lifting modules 2 are fixedly installed at the top of the base 1. A storage frame 4 is provided between the two sets of lifting modules 2. Each lifting module 2 includes two first support columns set at the top of the base 1. A second support column 41 is slidably installed on the top of each of the two first support columns. A moving groove 43 is opened on the inner side of each of the first and second support columns 41. A support block 42 is slidably installed in each of the two moving grooves 43. The opposite side of the two support blocks 42 is fixedly connected to the opposite side of the storage frame 4. A second push rod 44 is fixedly installed on the inner wall of the bottom end of each of the two moving grooves 43. The top of each of the two second push rods 44 is connected to the same... The bottom of the side support block 42 is fixedly connected. On the same side, the first support column and the second support column 41 are respectively equipped with a first support block 38 and a second support block 40 on the side away from the material storage box 4. A first push rod 39 is provided between the first support block 38 and the second support block 40 on the same side. After the equipment is stabilized, the first push rod 39 pushes the second support block 40 on the same side, which in turn lifts the second support column 41 on the same side, so that the top of the second support column 41 contacts the roof. The cooperation of the first support column and the second support column 41 stabilizes the equipment, which helps to maintain the stability of the equipment and ensures the accuracy of plastering. Then, the two second push rods 44 push the support block 42 on the same side to slide in the moving groove 43 on the same side. The two support blocks 43 lift the material storage box 4 and the scraper 6, which can then perform the plastering function.

[0049] The storage frame 4 is equipped with a stirring assembly, which includes two rotating rods 22 rotatably mounted inside the storage frame 4. Each of the two rotating rods 22 has multiple sets of stirring plates 28 arranged in a linear array on its sidewall. At least three stirring plates 28 in each set are arranged in a ring array on the sidewall of the same rotating rod 22. A first reduction motor 25 is fixedly mounted on the side of the storage frame 4 away from the scraper 6. A drive wheel 26 is fixedly sleeved on the sidewall of the output shaft of the first reduction motor 25. The ends of the two rotating rods 22 near the first reduction motor 25 penetrate the storage frame 4. Driven wheel 23s are fixedly sleeved on the sidewall of the ends of the two rotating rods 22 penetrating the storage frame 4. The drive wheel 26 has two grooves. Both the driven wheel 23 and the drive wheel 26 are fitted with belts 24. After the equipment is stabilized, the operator places cement in the storage box 4 and drives the drive wheel 26 to rotate through the first reduction motor 25. The drive wheel 26 drives the driven wheel 23 on the same side to rotate through the two belts 24. The two driven wheels 23 drive the rotating rod 22 in the same group to rotate. The rotating rod 22 drives the mixing plate 28 in the same group to rotate. Through the cooperation of multiple mixing plates 28, the cement can be mixed and stirred, which helps to maintain the quality of the cement. In addition, the top of the storage box 4 is equipped with two symmetrically distributed baffles, which helps to prevent cement from splashing out during the mixing process and reduces material waste.

[0050] A scraper 6 is provided on one side of the storage frame 4, and a baffle 5 is fixedly installed on the top of the scraper 6. Two telescopic rods 3 are symmetrically distributed between the scraper 6 and the opposite side of the storage frame 4. A conveying pipe 37 is fixedly installed on the inner wall of the bottom end of the storage frame 4. A conveying assembly is provided between the conveying pipe 37 and the scraper 6. The conveying assembly includes a support rod 33 rotatably installed in the conveying pipe 37. A spiral blade 32 is sleeved on the side wall of the support rod 33. An installation box 20 is fixedly installed on the side of the storage frame 4 away from the scraper 6. The installation box 20 is fixedly... A second geared motor 27 is fixedly installed. The end of the support rod 33 away from the scraper 6 passes through the storage frame 4 and extends into the mounting box 20. The end of the support rod 33 passing through the mounting box 20 is fixedly connected to the end of the output shaft of the second geared motor 27. The end of the conveying pipe 37 away from the mounting box 20 passes through the storage frame 4. A multi-port connector 21 is provided on the side of the scraper 6 near the storage frame 4. The end of the multi-port connector 21 away from the storage frame 4 passes through the scraper 6. A telescopic hose 29 is provided at the opposite end of the multi-port connector 21 and the conveying pipe 37.

[0051] The bottom inner wall of the storage frame 4 is inclined, and the feed port on the side wall of the conveying pipe 37 facilitates the entry of cement into the conveying pipe 37. Then, the second reduction motor 27 drives the support rod 33 to rotate, and the support rod 33 drives the spiral blade 32 to rotate. The extrusion force generated by the spiral blade 32 causes the cement to enter the telescopic hose 29 from the port of the conveying pipe 37. Subsequently, the cement enters the space between the scraper 6 and the wall through the multi-port connector 21. Then, the storage frame 4 and the scraper 6 are driven to rise synchronously by two sets of lifting modules 2, which can play the role of coating the wall. When the equipment is coating the wall, some cement may fall. The collection frame 7 can collect the fallen cement, which helps to reduce material waste.

[0052] The implementation principle of this utility model embodiment is as follows: When using the device, the operator places the collection frame 7 on one side of the base 1, so that the stabilizing block 16 and the locking block 17 installed on the side wall of the collection frame 7 engage with the groove 35 and the slot 36 opened on the side wall of the base 1, which can limit and fix the collection frame 7. Furthermore, the fixing component on the side wall of the base 1 restricts the fixing locking block 17, which helps maintain the stability of the assembly of the collection frame 7 and the base 1. The operator can move the device to the wall using the support and movement component. When the device is moved to the application position, the support and movement component moves into the storage slot 34 on the same side, and then the base plate 10 contacts the ground, thus supporting and stabilizing the device. A lifting component is provided between the base plate 10 and the base 1, which can adjust the height of the base plate 10. The placement of the equipment on uneven ground helps maintain its balance. Cement is then placed in the storage frame 4, which contains a mixing component to stir the cement, ensuring good mixing quality. Two symmetrically distributed baffles at the top of the storage frame 4 help prevent cement from splashing during mixing, reducing material waste. The telescopic rod 3 then drives the scraper 6 to contact the wall. The conveying component then guides the cement from the storage frame 4 between the scraper 6 and the wall. Finally, two sets of lifting modules 2 drive the storage frame 4 and scraper 6 to rise synchronously, thus applying the cement to the wall. During application, some cement may fall; the collection frame 7 collects this, further reducing waste.

[0053] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
