Description

Technical Field

[0001] The utility model relates to the field of decoration, in particular to a plastering machine for decoration engineering. Background Art

[0002] With the continuous development and improvement of the modern construction industry, the use of machines has become a trend, and the emergence of automatic plastering machines not only speeds up the progress of construction, but also effectively guarantees the quality of construction. Automatic plastering machines are suitable for a variety of walls and doors.

[0003] The traditional plastering machine for decoration projects still has certain shortcomings during use: when the current plastering machine is in use, workers need to manually pour mortar into the hopper with a material transport vehicle after the hopper drops to the bottom, and there is often a lot of mortar attached to the inside of the material transport vehicle, which needs to be scraped off with a shovel, which is inefficient to operate and requires a lot of labor for workers. Secondly, when the plastering machine is in use, its smoothed side needs to always be aimed at the wall, so some plastering machines now install guide rails at the bottom of the machine, but traditional guide rails are not easy to extend and fold, and are not convenient to fix on the ground.

[0004] Therefore, it is necessary to provide a new finishing project plastering machine to solve the problems of the technologies described above. Utility Model Content

[0005] The technical problem solved by the utility model is to provide a plastering machine for decoration engineering which has a guide rail structure which is convenient to fold, unfold and fix on the ground and can improve the injection efficiency and reduce the labor of workers.

[0006] In order to solve the above technical problems, the utility model provides a plastering machine for decoration engineering, comprising: a base, a limit assembly and a material injection assembly, wherein the bottom of the base is fixedly connected to a bracket, a positioning wheel is installed inside the bracket, the limit assembly comprises an outer guide rail, an inner guide rail is slidably connected inside the outer guide rail, the positioning wheel is located inside the outer guide rail, the front and rear side wall surfaces of the outer guide rail are fixedly connected to side frames, ratchets are arranged inside the side frames, a pawl is rotatably connected to the end of the inner guide rail, a spring rod is hinged between the pawl and the side wall of the inner guide rail, and the pawl is meshed with the ratchet;

[0007] First support members are vertically arranged at the edge positions of both sides of the top of the base, a platform is slidably connected between the two first support members, the injection assembly includes a injection box, the injection box is rotatably connected to the two first support members, a side surface of the injection box facing the platform is set to an opening structure, a scraper is slidably connected to the inside of the injection box, the scraper is fixedly connected to a counterweight block through a connecting rod, and the counterweight block is located outside the injection box, a side wall surface relatively far away from the two first support members is rotatably connected to a gear, the left and right side wall surfaces of the platform are fixedly connected to a rack, the rack is meshed with a gear on one side, a second wire wheel is fixedly connected to a side surface of the gear, and a second suspension rope is fixedly connected between the second wire wheel and the injection box.

[0008] As a further solution of the utility model, a guide wheel is fixedly connected to the surface of the first support member located on the upper side of the second wire wheel, the second suspension rope passes through the surface of the guide wheel, and the height of the guide wheel is higher than the injection box.

[0009] With the above technical solution, when the current plastering machine is in use, workers need to manually pour mortar into the hopper with a material transport vehicle after the hopper drops to the bottom. There is often a lot of mortar attached to the inside of the material transport vehicle, which needs to be scraped off with a shovel. The operation is inefficient and the workers have a lot of labor. In this device, when the platform rises, a worker on the side can manually shovel the mortar mixed manually or by machine on the ground into the injection box. At this time, the end of the injection box close to the counterweight block is tilted downward, and the mortar itself has a high viscosity, so the inside can be filled with the mortar required for one plastering. And it will not flow away from the opening side. When the platform is finished plastering and descends, the rack on one side of the platform will mesh with the gear and drive the second wire wheel to reel in the second lifting rope, so that the end of the injection box begins to rise, and the mortar inside the injection box will also be poured into the hopper. In order to prevent the mortar from adhering to the inner wall of the injection box, a counterweight block is specially designed in the structure. When the injection box is tilted at a certain angle, the counterweight block drops under the action of gravity, and will push the scraper to scrape the mortar on the inner wall of the injection box to complete the cleaning of the remaining material. This structural design does not require manual pouring and scraping of materials, which can reduce the burden on workers.

[0010] As a further solution of the utility model, a hopper is rotatably connected to the top of the platform, a telescopic cylinder is rotatably connected between the bottom of the hopper and the surface of the platform, and the hopper is located at the lower side of the injection box.

[0011] Through the above technical solution, a telescopic cylinder is installed at the bottom of the hopper. In the process of the platform rising, the telescopic cylinder can push the bottom of the hopper to move the mortar inside it to the side of the wall. At this time, the plane of the platform facing the wall acts as a smear to apply the mortar on the wall. This is the prior art.

[0012] As a further solution of the utility model, the end of the inner guide rail relative to the outer guide rail is fixedly connected to a pressure plate through a spring, and the left and right side walls of the inner guide rail and the outer guide rail are fixedly connected to ear plates, and the surface of the ear plates is provided with fixing holes.

[0013] Through the above technical scheme, when the plastering machine is in use, its smoothing side needs to always be aligned with the wall. Therefore, some plastering machines now install guide rails at the bottom of the machine, but traditional guide rails are not easy to stretch and fold, and are not convenient to fix on the ground. The device is provided with a retractable outer guide rail and an inner guide rail, and the inner guide rail and the outer guide rail are connected by a pawl and a ratchet. In this way, when installing, the user can first press one end of the outer guide rail against one end of the wall, and then pull out the inner guide rail until the pressure plate at the end of the inner guide rail abuts against the wall at the other end. Due to the engagement of the pawl and the ratchet, the inner guide rail cannot retreat, and the compressed spring between the pressure plate and the inner guide rail will limit the limit assembly here through the reaction force. For stability considerations, the user can also fix the assembly to the ground through the ground nails and the ear plates. After use, the user can disengage the pawl from the engagement with the ratchet by pushing the toggle block inward, thereby facilitating folding and making the structural design more user-friendly.

[0014] As a further solution of the utility model, the first support member is internally slidably connected to a second support member, a limiting wheel is installed on the top of the second support member, a first wire wheel is rotatably connected to one side of the first support member through a connecting block, a first lifting rope is fixedly connected between the first wire wheel and the platform, and the first lifting rope passes through the surface of the limiting wheel.

[0015] Through the above technical solution, the first lifting rope is retracted through the first wire wheel, so that the platform can be moved upward along the first support member and the second support member. At this time, the mortar in the hopper will move to one side of the wall and enter the gap between the platform and the wall, thereby completing the plastering work of the wall.

[0016] As a further solution of the utility model, the first support member on one side is fixedly connected to the drive motor through a connecting member, a transmission rod is fixedly connected between the two first wire wheels, and the transmission rod and the output end of the drive motor are transmitted through a chain and a sprocket.

[0017] Through the above technical solution, when the driving motor rotates, the synchronous belt on one side will drive the transmission rod to rotate, and then drive the first wire wheels on both sides to rotate synchronously to realize the lifting and lowering of the platform.

[0018] As a further solution of the utility model, universal wheels are installed at the four corners of the bottom of the base, a transverse groove is opened on the surface of the side frame, a toggle block is fixedly connected to the surface of the pawl, and the toggle block extends to the outside of the side frame through the transverse groove.

[0019] With the above technical solution, when the user pushes the toggle block inward, the pawl and the ratchet teeth will disengage, so that the inner guide rail can be retracted into the inner part of the outer guide rail. After that, the user releases his hand, and the pawl will re-engage with the ratchet teeth under the reaction force of the spring rod.

[0020] Compared with the related art, the plastering machine for decoration engineering provided by the utility model has the following beneficial effects:

[0021] 1. In the present utility model, when the existing plastering machine is in use, workers need to manually pour mortar into the hopper with a material transport vehicle after the hopper drops to the bottom. Moreover, there is often a lot of mortar attached to the inside of the material transport vehicle, which needs to be scraped off with a shovel. The operation is inefficient and the workers have a lot of labor. In this device, when the platform rises, a staff member on the side can manually shovel the mortar mixed manually or by machine on the ground into the injection box. At this time, the end of the injection box close to the counterweight block is tilted downward. In addition, the mortar itself has a high viscosity, so the inside can be filled with the mortar required for one plastering. And it will not flow away from the side of the opening. When the platform is finished plastering and descends, the rack on one side of the platform will mesh with the gear and drive the second wire wheel to reel in the second hanging rope, so that the end of the injection box begins to rise, and the mortar inside the injection box will also be poured into the hopper. In order to prevent the mortar from adhering to the inner wall of the injection box, a counterweight block is specially designed in the structure. When the injection box is tilted at a certain angle, the counterweight block falls under the action of gravity, and it will push the scraper to scrape the mortar on the inner wall of the injection box to complete the cleaning of the residual material. This structural design does not require manual pouring and scraping of materials, which can reduce the burden on workers;

[0022] 2. In the utility model, when the plastering machine is in use, its smoothing side needs to always be aligned with the wall. Therefore, some plastering machines now have guide rails installed on the bottom of the machine. However, traditional guide rails are not easy to stretch and fold, and are not convenient to fix on the ground. The device is provided with a retractable outer guide rail and an inner guide rail, and the inner guide rail and the outer guide rail are connected by a pawl and a ratchet. In this way, when installing, the user can first put one end of the outer guide rail against one end of the wall, and then pull out the inner guide rail until the pressure plate at the end of the inner guide rail abuts against the wall at the other end. Due to the engagement of the pawl and the ratchet, the inner guide rail cannot retreat, and the compressed spring between the pressure plate and the inner guide rail will limit the limit assembly here through the reaction force. For stability considerations, the user can also fix the assembly on the ground through the ground nails and the ear plates. After use, the user can disengage the pawl from the engagement with the ratchet by pushing the toggle block inwards, thereby facilitating folding and making the structural design more user-friendly.

Figure 2 A plastering machine for decoration engineering includes:

[0031] A base 1, a limit assembly 2 and an injection assembly 3, the bottom of the base 1 is fixedly connected with a bracket, a positioning wheel 22 is installed inside the bracket, the limit assembly 2 includes an outer guide rail 4, the inner guide rail 5 is slidably connected inside the outer guide rail 4, the positioning wheel 22 is located inside the outer guide rail 4, the front and rear side wall surfaces of the outer guide rail 4 are fixedly connected with side frames 12, the side frames 12 are provided with ratchet teeth 27, the end of the inner guide rail 5 is rotatably connected with a pawl 29, a spring rod 28 is hinged between the pawl 29 and the side wall of the inner guide rail 5, and the pawl 29 is meshed with the ratchet teeth 27;

[0032] First support members 6 are vertically arranged at the edge positions of both sides of the top of the base 1, and a platform 17 is slidably connected between the two first support members 6. The injection assembly 3 includes a injection box 24, which is rotatably connected to the two first support members 6. The side surface of the injection box 24 facing the platform 17 is set as an open structure, and a scraper 25 is slidably connected to the inside of the injection box 24. The scraper 25 is fixedly connected to a counterweight 23 through a connecting rod. The counterweight 23 is located outside the injection box 24, and a side wall surface relatively far away from the two first support members 6 is rotatably connected to a gear 21. The left and right side wall surfaces of the platform 17 are fixedly connected to a rack 20, and the rack 20 is meshed with a gear 21 on one side. A second wire wheel 26 is fixedly connected to a side surface of the gear 21, and a second suspension rope 9 is fixedly connected between the second wire wheel 26 and the injection box 24.

[0033] like Figure 1-4 As shown, a guide wheel 16 is fixedly connected to the surface of the first support member 6 located on the upper side of the second wire wheel 26 , and the second suspension rope 9 passes through the surface of the guide wheel 16 . The height of the guide wheel 16 is higher than the injection box 24 .

[0034] When the existing plastering machine is in use, workers need to manually pour mortar into the hopper 18 with a material transport vehicle after the hopper 18 drops to the bottom. There is often a lot of mortar attached to the inside of the material transport vehicle, which needs to be scraped off with a shovel. The operation is inefficient and the workers have a lot of labor. In this device, when the platform 17 rises, a staff member on the side can manually shovel the mortar mixed manually or by machine on the ground into the injection box 24. At this time, the end of the injection box 24 close to the counterweight 23 is tilted downward. In addition, the mortar itself has a high viscosity, so the inside can be filled with the mortar required for one plastering, and it will not flow out from one side of the opening, and the leveling When the platform 17 completes plastering and descends, the rack 20 on one side of the platform 17 will mesh with the gear 21, and drive the second wire wheel 26 to reel in the second suspension rope 9, so that the end of the injection box 24 begins to rise, and the mortar inside the injection box 24 will also be poured into the hopper 18. In order to prevent the mortar from adhering to the inner wall of the injection box 24, a counterweight block 23 is specially designed in the structure. When the injection box 24 tilts at a certain angle, the counterweight block 23 descends due to gravity, and will push the scraper 25 to scrape the mortar on the inner wall of the injection box 24 to complete the cleaning of the remaining material. This structural design does not require manual pouring and scraping of materials, which can reduce the burden on workers.

[0035] like Figure 1-4 As shown, a hopper 18 is rotatably connected to the top of the platform 17 , a telescopic cylinder 19 is rotatably connected between the bottom of the hopper 18 and the surface of the platform 17 , and the hopper 18 is located at the lower side of the injection box 24 .

[0036] By installing a telescopic cylinder 19 at the bottom of the hopper 18, the telescopic cylinder 19 can push the bottom of the hopper 18 during the rising process of the platform 17, so that the mortar inside it moves to the side of the wall. At this time, the plane of the platform 17 facing the wall acts as a smear to apply the mortar on the wall. This is the prior art.

[0037] like Figure 1-4 As shown, the end of the inner guide rail 5 relative to the outer guide rail 4 is fixedly connected to a pressure plate 15 via a spring, and the left and right side walls of the inner guide rail 5 and the outer guide rail 4 are fixedly connected to ear plates, and fixing holes are opened on the surface of the ear plates.

[0038] When the plastering machine is in use, its smoothing side needs to be always aligned with the wall. Therefore, some plastering machines now have guide rails installed at the bottom of the machine, but traditional guide rails are not easy to stretch and fold, and are not convenient to fix on the ground. The device is provided with a retractable outer guide rail 4 and an inner guide rail 5, and the inner guide rail 5 is connected to the outer guide rail 4 by a pawl 29 and a ratchet 27. In this way, when installing, the user can first put one end of the outer guide rail 4 against one end of the wall, and then pull out the inner guide rail 5 until the end of the inner guide rail 5 is The pressure plate 15 at the top abuts against the wall at the other end. Due to the engagement of the pawl 29 and the ratchet 27, the inner guide rail 5 cannot retreat, and the compressed spring between the pressure plate 15 and the inner guide rail 5 will limit the limit assembly 2 here through the reaction force. For stability considerations, the user can also fix the assembly to the ground through ground nails and ear plates. After use, the user can disengage the pawl 29 from the engagement with the ratchet 27 by pushing the toggle block 14 inward, thereby folding easily and making the structural design more user-friendly.

[0039] like Figure 1-4 As shown, the first support member 6 is internally slidably connected to the second support member 7, a limiting wheel is installed on the top of the second support member 7, and a first wire wheel 10 is rotatably connected to one side of the first support member 6 through a connecting block. A first lifting rope 8 is fixedly connected between the first wire wheel 10 and the platform 17, and the first lifting rope 8 passes through the surface of the limiting wheel.

[0040] By retracting the first hanging rope 8 through the first wire wheel 10, the platform 17 can be moved up along the first support member 6 and the second support member 7. At this time, the mortar in the hopper 18 will move to one side of the wall and enter the gap between the platform 17 and the wall, thereby completing the plastering work of the wall.

[0041] like Figure 1-4 As shown, the first support member 6 on one side is fixedly connected to the drive motor 11 through a connecting member, a transmission rod is fixedly connected between the two first wire wheels 10, and the transmission rod and the output end of the drive motor 11 are transmitted through a chain and a sprocket.

[0042] When the driving motor 11 rotates, the synchronous belt on one side will drive the transmission rod to rotate, and then drive the first wire wheels 10 on both sides to rotate synchronously to realize the lifting and lowering of the platform 17.

[0043] like Figure 1-4 As shown, universal wheels are installed at the four corners of the bottom of the base 1, a transverse groove 13 is opened on the surface of the side frame 12, and a toggle block 14 is fixedly connected to the surface of the pawl 29, and the toggle block 14 extends to the outside of the side frame 12 through the transverse groove 13.

[0044] When the user pushes the toggle block 14 inward, the pawl 29 and the ratchet 27 are disengaged, so that the inner guide rail 5 can be retracted into the inner part of the outer guide rail 4. Then, the user releases his hand, and the pawl 29 re-engages with the ratchet 27 under the reaction force of the spring rod 28.

[0045] The working principle of a plastering machine for decoration engineering provided by the utility model is as follows:

[0046] First step: When the current plastering machine is in use, workers need to manually pour mortar into the hopper 18 with a material transport vehicle after the hopper 18 drops to the bottom. There is often a lot of mortar attached to the inside of the material transport vehicle, which needs to be scraped off with a shovel. The operation is inefficient and the workers have a lot of labor. When the platform 17 rises in the device, the end of the injection box 24 close to the counterweight block 23 tilts downward. In addition, the mortar itself has a high viscosity, so the inside of the box can be filled with the mortar required for one plastering, and it will not flow out from the side of the opening. The staff on the side can manually shovel the mortar mixed by hand or machine on the ground into the injection box 24 When the platform 17 is finished plastering and descends, the rack 20 on one side of the platform 17 will mesh with the gear 21, and drive the second wire wheel 26 to reel in the second suspension rope 9, so that the end of the injection box 24 begins to rise, and the mortar inside the injection box 24 will also be poured into the hopper 18. In order to prevent the mortar from adhering to the inner wall of the injection box 24, a counterweight block 23 is specially designed in the structure. When the injection box 24 is tilted at a certain angle, the counterweight block 23 descends under the action of gravity, and pushes the scraper 25 to scrape the mortar on the inner wall of the injection box 24 to complete the cleaning of the residual material. This structural design does not require manual pouring and scraping of materials, which can reduce the burden on workers;

[0047] The second step: When the plastering machine is in use, its smoothing side needs to be always aligned with the wall. Therefore, some plastering machines now have guide rails installed at the bottom of the machine, but traditional guide rails are not easy to stretch and fold, and are not convenient to fix on the ground. The device is provided with a retractable outer guide rail 4 and an inner guide rail 5, and the inner guide rail 5 is connected to the outer guide rail 4 by a pawl 29 and a ratchet 27. In this way, when installing, the user can first put one end of the outer guide rail 4 against one end of the wall, and then pull out the inner guide rail 5 until the inner guide rail 4 is The pressure plate 15 at the end of 5 abuts against the wall at the other end. Due to the engagement of the pawl 29 and the ratchet 27, the inner guide rail 5 cannot retreat, and the compressed spring between the pressure plate 15 and the inner guide rail 5 will limit the limit assembly 2 here through the reaction force. For stability considerations, the user can also fix the assembly on the ground through the ground nails and the ear plates. After use, the user can push the toggle block 14 inward to disengage the pawl 29 from the ratchet 27, thereby folding easily and making the structural design more user-friendly.
