Description

Technical Field

[0001] The utility model relates to the technical field of building construction, in particular to a concrete wall trowel machine. Background Art

[0002] When constructing a building wall, concrete mortar is usually applied on the wall. In order to ensure the flatness of the concrete mortar, a trowel is usually used to smooth the wall. During the smoothing process of the wall, the operator holds the trowel and then operates the trowel to smooth the wall. Since the trowel needs to be held in hand all the time during the smoothing process of the wall, and the smoothing surface of the trowel is usually small and fixed in size, when the trowel is manually held to smooth the concrete wall, the operation labor intensity is large and the smoothing efficiency of the concrete wall is low. Therefore, a concrete wall trowel is proposed to address the above problems. Utility Model Content

[0003] The technical problem to be solved by the utility model overcomes the existing defects and can effectively solve the problems in the background technology.

[0004] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0005] A concrete wall trowel machine comprises a bracket, wherein the right end of the bracket is fixedly connected with a handle, the top right end of the bracket is fixedly connected with a controller, the bottom right end of the bracket is fixedly connected with a battery, the top inner side of the bracket is slidably connected with a bracket, the top inner side of the bracket and the bottom inner side of the bracket are both fixedly connected with an electric conveying roller, the outer side of the electric conveying roller contacts with a conveyor belt, the outer side of the conveyor belt is fixedly connected with a trowel layer, the inner bottom end of the bracket is spirally connected with a two-way threaded shaft, the outer bottom end of the two-way threaded shaft is spirally connected with a positioning bracket slidably connected to the bracket, the left end of the positioning bracket is slidably connected with a fixed plate, the inner side of the fixed plate is slidably connected with a fixing rod penetrating the fixing plate, the bottom end of the fixing rod is fixedly connected with a connecting frame, and the inner side of the connecting frame is rotatably connected with a supporting shaft in contact with the trowel layer via a rotating shaft.

[0010] Compared with the prior art, the utility model has the following beneficial effects:

[0011] 1. A concrete wall trowel machine, which is equipped with an electric conveying roller, a trowel layer, a conveyor belt, a bidirectional threaded shaft, a worm and a support frame. When the device is used to trowel the concrete wall, the worm is first rotated to engage the worm wheel so that the bidirectional threaded shaft is spirally connected with the positioning frame and the support frame, and the trowel height of the device is further adjusted according to the height of the troweled wall. Then, the device is pushed to make the left end of the trowel layer contact the wall, and then the electric conveying roller is started to drive the trowel layer outside the conveyor belt to move, so that the concrete wall can be troweled. By adjusting the trowel height of the device according to the height of the concrete wall, when the device is pushed to contact the wall to perform the troweling operation on the concrete wall, the troweling efficiency of the concrete wall is improved and the labor intensity of the operator is reduced.

[0012] 2. A concrete wall finishing machine, which is provided with a pressure block, a pressure sensor, a fixed plate, an adjusting threaded shaft, a connecting frame and a supporting shaft. When the device is used to finish the concrete wall, when the device is used for a long time and the finishing layer on the outside of the conveyor belt and the finishing layer on the outside thereof are loosened, the finishing effect on the concrete wall is deteriorated, the force of the fixed plate compressing the spring becomes smaller, the force of the pressure block pressing the pressure sensor becomes smaller, and the pressure value detected by the pressure sensor is lower than the set range. When the signal light is observed to light up and it is determined that the conveyor belt and the finishing layer on the outside thereof are loose, the adjusting threaded shaft is rotated to be spirally connected with the fixed plate, and the fixed plate is further compressed upward by the spring, so that the force of the pressure block pressing the pressure sensor is continuously increased. When the pressure value detected by the pressure sensor reaches the set range and the signal light is off, it is convenient to automatically detect the conveyor belt and the finishing layer on the outside thereof when they are loose, and it is convenient for the operator to tension the conveyor belt and the finishing layer on the outside thereof in time, thereby ensuring the finishing effect of the concrete wall.

[0018] Example 1

[0019] like Figure 1-2 As shown, a concrete wall finishing machine comprises a bracket 1, wherein the right end of the bracket 1 is fixedly connected with a handle 2, the top right end of the bracket 1 is fixedly connected with a controller 3, the bottom right end of the bracket 1 is fixedly connected with a battery 4, the top inner side of the bracket 1 is slidably connected with a bracket 5, the top inner side of the bracket 5 and the bottom inner side of the bracket 1 are both fixedly connected with an electric conveying roller 6, the outer side of the electric conveying roller 6 is in contact with a conveyor belt 7, the outer side of the conveyor belt 7 is fixedly connected with a finishing layer 8, the bottom inner side of the bracket 5 is spirally connected with a two-way threaded shaft 9, the bottom outer side of the two-way threaded shaft 9 is spirally connected with a positioning frame 12 slidably connected with the bracket 1, the left end of the positioning frame 12 is slidably connected with a fixing plate 13, the inner side of the fixing plate 13 is slidably connected with a fixing rod 14 penetrating the fixing plate 13, the bottom end of the fixing rod 14 is fixedly connected with a connecting frame 15, and the inner side of the connecting frame 15 is rotatably connected with a supporting shaft 16 in contact with the finishing layer 8 through a rotating shaft.

[0020] Example 2

[0021] like Figure 1-2As shown, in order to solve the problem that it is inconvenient to adjust the height of the smoothing device according to the height of the concrete wall, a worm wheel 10 is fixedly connected to the center of the outer side of the bidirectional threaded shaft 9, and a worm 11 that penetrates the bracket 1 is meshedly connected to the outer side of the worm wheel 10, and the worm 11 is rotatably connected to the bracket 1. By rotating the worm 11 to mesh the worm wheel 10, the bidirectional threaded shaft 9 is further driven to be spirally connected to the support frame 5 and the positioning frame 12 at the same time, which facilitates the adjustment of the height of the smoothing device according to the height of the concrete wall.

[0022] Example 3

[0023] like Figure 2 As shown, in order to solve the problem that the height of the conveyor belt 7 and the polishing layer 8 on its outer side cannot be adjusted normally, the bidirectional threaded shaft 9 passes through the bracket 1, and the bidirectional threaded shaft 9 is rotatably connected to the bracket 1, the thread direction on one side of the bidirectional threaded shaft 9 is opposite to the thread direction on the other side of the bidirectional threaded shaft 9, and the bidirectional threaded shaft 9 is symmetrically arranged, and the bidirectional threaded shaft 9 with opposite thread directions on both sides is spirally connected to the support frame 5 and the positioning frame 12, and the support frame 5 and the positioning frame 12 are further made to approach or move away from each other. When the electric conveyor roller 6 and the support shaft 16 at the top are close to or away from each other, it is ensured that the height of the conveyor belt 7 and the polishing layer 8 on its outer side can be adjusted normally.

[0024] Example 4

[0025] like Figure 1-2 As shown, in order to solve the problem that the conveyor belt 7 and the polishing layer 8 on its outside cannot be detected when they are loose, a pressure block 17 and a spring 18 are arranged up and down at the top of the outer side of the fixed rod 14, and the pressure block 17 is slidably connected to the fixed rod 14, and the spring 18 is fixedly connected to the pressure block 17 and the fixed plate 13. A pressure sensor 19 in contact with the fixed rod 14 is fixedly connected to the top of the pressure block 17, and a signal light 20 is fixedly connected to the top of the fixed rod 14. When the conveyor belt 7 and the polishing layer 8 on its outside are loosened, the force of the fixed plate 13 pressing the spring 18 becomes smaller, and the force of the pressure block 17 pressing the pressure sensor 19 becomes smaller. When the pressure value detected by the pressure sensor 19 is lower than the set range, causing the signal light 20 to light up, it is achieved to detect the conveyor belt 7 and the polishing layer 8 on its outside when they are loose.

[0026] Example 5

[0027] like Figure 2As shown, in order to solve the problem that the conveyor belt 7 and the polishing layer 8 on its outer side cannot be tensioned when they are loose, the inner right end of the fixed plate 13 is spirally connected with an adjusting threaded shaft 21 that penetrates the fixed plate 13 and the positioning frame 12, and the adjusting threaded shaft 21 is rotatably connected to the positioning frame 12. By rotating the adjusting threaded shaft 21 that is spirally connected to the fixed plate 13, the conveyor belt 7 and the polishing layer 8 on its outer side are further pulled up through the fixing rod 14, the connecting frame 15 and the supporting shaft 16, which facilitates the tensioning of the conveyor belt 7 and the polishing layer 8 on its outer side when they are loose.

[0028] In this embodiment, when the concrete wall surface is smoothed by the device, the sensing range of the pressure sensor 19 is set in advance by the controller 3. After setting, the worm 11 is first rotated to engage the worm wheel 10 so that the two-way threaded shaft 9 with opposite thread directions on both sides is spirally connected with the positioning frame 12 and the support frame 5, and the smoothing height of the device is further adjusted according to the height of the smoothed wall surface. At this time, the support frame 5 will drive the top electric conveying roller 6 to move upward, and the positioning frame 12 will drive the support shaft 16 to move downward through the fixing plate 13, the fixing rod 14 and the connecting frame 15. When the smoothing height of the device is adjusted, the handle 2 is used to push the device so that the left end of the smoothing layer 8 contacts the concrete wall surface, and then the controller 3 is used to start the electric conveying roller 6 to drive the smoothing layer 8 on the outside of the conveyor belt 7 to move. At this time, the concrete wall surface can be smoothed by the moving smoothing layer 8. When a smoothing operation is completed, only It is sufficient to adjust the finishing position of the device. In the process of using the device to finish the concrete wall, when the device has been used for a long time, the conveyor belt 7 and the finishing layer 8 on its outer side become loose, and the finishing effect on the concrete wall becomes worse. At this time, the force of the spring 18 compressed by the fixed plate 13 becomes smaller, and the force of the pressure block 17 pressing the pressure sensor 19 becomes smaller, and the force value detected by the pressure sensor 19 will be lower than the set range. The signal light 20 will light up to remind the operator, and then the adjustment threaded shaft 21 is spirally connected to the fixed plate 13 by rotating to further make the fixed plate 13 continue to compress the spring 18, so that the force of the pressure block 17 pressing the pressure sensor 19 continues to increase. When the pressure value detected by the pressure sensor 19 reaches the set range and the signal light 20 goes out, it is convenient to timely tension the conveyor belt 7 and the finishing layer 8 on its outer side, thereby ensuring the finishing effect of the concrete wall.
