[0003] During the construction of corundum flooring, workers are required to enter the concrete floor to spread the corundum, and then use a trowel to perform smoothing operations. However, this will cause damage to the poured concrete base due to the workers' feet. Even if smoothing operations are performed later, insufficient smoothing may occur in some locations, resulting in low flatness, which is not conducive to improving the construction quality of the floor. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a floor construction device with high flatness, which solves the problem in the prior art that workers need to enter the concrete floor to spread corundum and then use a trowel to perform the smoothing operation. However, this will cause damage to the poured concrete base by the workers' feet. Even if the smoothing operation is performed later, the problem of low flatness will occur due to insufficient smoothing of some positions, which is not conducive to improving the construction quality of the floor.

[0005] The technical problem to be solved by the utility model is achieved by adopting the following technical scheme: a high-flatness floor construction device, including a paving base and load-bearing columns, the load-bearing columns are vertically embedded and connected to the paving base, two groups of load-bearing columns are arranged side by side and a number of columns are arranged side by side in each group, and also includes sliding rails, screws, driving motors, moving boxes, discharge frames, shaking boxes and fixed baffles, the sliding rails are arranged on opposite sides of the two groups of load-bearing columns, the sliding rails are fixedly connected to the load-bearing columns, the extending direction of the sliding rails is the same as the arrangement direction of the several load-bearing columns in each group, the driving motor is fixed at one end of the sliding rails, one end of the screw is connected to the driving motor power, the other end of the driving motor extends into the screw and is connected to the screw for rotation, the extending direction of the driving motor is the same as that of the sliding rails, both ends of the moving box extend into the sliding rails and slide in cooperation with the sliding rails, and the driving motor penetrates the sliding rails It passes through the two ends of the moving box and is threadedly connected with the moving box. The moving box is hollow to form a shaking cavity. The discharge frame is fixed on the side of the moving box away from the laying base. A feeding channel connecting the inner side of the discharge frame with the shaking cavity is provided at the connection between the discharge frame and the moving box. A discharge channel connecting the shaking cavity with the outside of the moving box is provided on the side of the shaking cavity facing the laying base. The shaking box is arranged in the shaking cavity. The interior of the shaking box is hollow and forms a dispersion cavity. An opening is provided on the side of the dispersion cavity facing the discharge channel and a through opening is provided on the side facing the feed channel. A number of fixed baffles are provided. One end of the fixed baffle is fixed on the vertical side wall of the dispersion cavity and the fixed baffle extends obliquely toward the direction of the discharge channel. A gap is formed between the other end of the fixed baffle and the other vertical side wall of the dispersion cavity. Adjacent fixed baffles are staggered along relative vertical side walls.

[0006] By adopting the above technical scheme, the floor is laid on the paving base. After the foundation cement of the floor is laid, corundum needs to be laid on the cement. At this time, the drive motor is started to drive the screw to rotate, and the moving box slides along the extension direction of the sliding track under the action of the threaded connection. In this process, the corundum is poured into the discharge frame. Under the action of gravity, the corundum passes through the feed channel into the inside of the shaking box in the shaking chamber, that is, the inside of the dispersion chamber. At this time, the corundum contacts the fixed baffle, and the fixed baffle prevents the corundum from passing through the dispersion chamber quickly, so as to achieve the purpose of slowing down the falling speed of the corundum, and avoid the corundum directly and quickly passing through the dispersion chamber and being sprinkled on the cement surface through the discharge channel, so as to achieve a more balanced density of the corundum spreading. In the entire construction process, the traditional manual corundum spreading steps are changed, so that workers do not need to step on the cement for spreading, and the flatness of the cement surface after spreading can be preserved, which is beneficial to improving the construction quality of the floor.

[0007] The utility model is further configured as follows: a movable baffle is provided on one side of the dispersion chamber close to the discharge channel, one end of the movable baffle is hinged to an end wall on a side opposite to an adjacent fixed baffle and a torsion spring is fixedly provided at the hinge, and a first sealing sheet is fixedly provided between the other end of the movable baffle and an end wall on one side of the dispersion chamber close to the discharge channel.

[0008] By adopting the above technical solution, when there is too much corundum remaining in the dispersion chamber, the weight of the corundum accumulated on the movable baffle is relatively large. The movable baffle is pressed and flipped along the hinged end to compress the torsion spring. At this time, the gap between the free end of the movable baffle and the inner wall of the dispersion chamber becomes larger, and more corundum can pass through per unit time, avoiding the accumulation of corundum inside the dispersion chamber to cause blockage and affect the normal scattering of corundum. When there is less corundum remaining in the dispersion chamber, the torsion spring pushes the movable baffle to reset and flip, and the corundum can be sprinkled normally at the initial rate, thereby achieving the purpose of freely adjusting the corundum scattering rate.

[0009] The utility model is further configured as follows: the shaking box is slidably connected to the inner wall of the shaking chamber and the sliding direction is the same as the extension direction of the sliding track, and spring grooves are provided on the opposite end walls of the shaking chamber at both ends of the extension direction of the moving box body, and the shaking box extends into the spring groove, and a spring is arranged in the spring groove, one end of the spring is fixedly connected to the shaking box, and the other end of the spring is fixedly connected to the inner wall of the spring groove, the elastic force direction of the spring is the same as the sliding direction of the shaking box, and a driving structure for driving the shaking box to slide is arranged in the shaking chamber.

[0010] The utility model is further configured as follows: the driving structure includes a cam, a cam motor and a support member; the cam is rotatably arranged on the inner wall of the shaking cavity and the outer side surface of the cam is always in contact with the outer side surface of the shaking box; the cam motor is coaxially arranged with the rotating shaft of the cam and is dynamically connected to the cam; during the rotation process, the cam drives the shaking box to slide in the spring groove; the support member fixedly connects the cam motor to the inner wall of the shaking cavity.

[0011] The utility model is further configured as follows: a second sealing sheet is fixedly arranged between the opening of the dispersion chamber facing the laying base layer and the discharge channel.

[0012] By adopting the above technical solution, when the cam motor is started, it drives the cam to rotate. Due to the contour of the outer curved surface of the cam, the shaking box slides along the extension direction of the spring groove. In this process, the spring makes the shaking box always slide and abut against the outer side surface of the cam under the elastic action. At this time, the shaking box can shake continuously. At this time, the corundum in the shaking box can slide evenly from the fixed baffle under the shaking action and finally fall onto the cement surface through the above process, which is beneficial to further ensure that the scattered corundum is uniform and at a constant speed. The second sealing plate can separate the shaking chamber and the dispersion chamber to prevent the corundum from entering the shaking chamber due to the shaking of the shaking box and remaining therein, thereby ensuring the normal operation of the shaking box and reducing the waste of corundum.

[0016] By adopting the above technical solution, during the movement of the moving box, the adjustment plate on the side away from the moving direction of the moving box selects the limiting hole at the appropriate position, so that the end of the trowel plate away from the adjustment plate abuts against the concrete surface, and the limiting pin is inserted to fix it, and then the tightening nut is rotated to increase the abutting pressure between the tightening nut and the adjustment plate. At this time, the trowel plate cannot be turned freely, and the adjustment plate on the side facing the moving direction of the moving box selects the limiting hole at the appropriate position so that the trowel plate cannot contact the cement surface.

The fixed plates 22 are fixedly arranged on the two end surfaces in the extension direction of the moving box 20 and the fixed plates 22 extend to the side of the moving box 20 in the direction of the laying base layer 10. The adjusting plate 24 is hinged on the side of the moving box 20 facing the laying base layer 10. Two adjusting plates 24 are provided and the two adjusting plates 24 are respectively located on both sides of the moving box 20 in the sliding direction. The smoothing plate 23 is hinged on the side of the adjusting plate 24 away from the hinged end. The adjusting structure is arranged on the fixed plate 22 and connected to the adjusting plate 24. The locking structure is arranged at the hinge between the smoothing plate 23 and the adjusting plate 24. The adjustment structure includes a limit hole 26 and a limit pin 27.

[0029] like Figure 4 and Figure 6As shown, a splicing plate 15 located on the side of the sliding track 12 is fixed to one end face of the sliding track 12 where the driving motor 14 is arranged, and a splicing groove 16 capable of being plugged with the splicing plate 15 is provided on the end face of the sliding track 12 away from the driving motor 14. When two sliding tracks 12 are spliced ​​with each other, the splicing plate 15 of one sliding track 12 is inserted into the splicing groove 16 of the other sliding track 12 to complete the splicing. At this time, the length of the sliding track 12 can be extended, thereby increasing the construction range of the construction device.

[0030] After the moving box 20 moves, the diamond sand is poured in through the material discharging frame 21. At this time, the workers can stand between the adjacent load-bearing columns 11, that is, on both sides of the extension direction of the floor. The floor is laid on the paving base 10. After the foundation cement of the floor is laid, corundum needs to be laid on the cement. At this time, the driving motor 14 is started to drive the driving motor 14 to drive the screw 13 to rotate, and the moving box 20 slides along the extension direction of the sliding track 12 under the action of the threaded connection. In this process, the corundum is poured into the discharge frame 21. Under the action of gravity, the corundum passes through the feed channel 25 into the shaking box 30 in the shaking chamber 31, that is, the dispersion chamber 32. At this time, the corundum contacts the fixed baffle 33, and the fixed baffle 33 prevents the corundum from passing through the dispersion chamber 32 quickly, so as to achieve the purpose of slowing down the scattering speed of the corundum, and avoid the corundum directly and quickly passing through the dispersion chamber 32 and being sprinkled on the cement surface through the discharge channel 36, so as to achieve a more balanced density of the corundum spreading. In the entire construction process, the traditional manual corundum spreading steps are changed, so that workers do not need to step on the cement for spreading, and the flatness of the cement surface after spreading can be not damaged, which is beneficial to improving the construction quality of the floor.

[0031] When there is too much corundum remaining in the dispersion chamber 32, the weight of the corundum accumulated on the movable baffle 34 is relatively large. The movable baffle 34 is pressed and flipped along the hinged end to compress the torsion spring. At this time, the gap between the free end of the movable baffle 34 and the inner wall of the dispersion chamber 32 becomes larger, and more corundum can pass through per unit time, avoiding the accumulation of corundum inside the dispersion chamber 32 to cause blockage and affect the normal scattering of corundum. When there is less corundum remaining in the dispersion chamber 32, the torsion spring pushes the movable baffle 34 to reset and flip, and the corundum can be sprinkled normally at the initial rate, thereby achieving the purpose of freely adjusting the corundum scattering rate.

[0032] When the cam motor 43 is started, it drives the cam 42 to rotate. Due to the contour of the outer curved surface of the cam 42, the shaking box 30 slides along the extension direction of the spring groove 40. During this process, the spring 41 makes the shaking box 30 always slide and abut against the outer side surface of the cam 42 under the elastic action. At this time, the shaking box 30 can shake continuously. At this time, the corundum in the shaking box 30 can slide evenly from the fixed baffle 33 under the action of shaking, and finally fall onto the cement surface through the above process, which is conducive to further ensuring that the scattered corundum is uniform and at a constant speed, and the second sealing plate 37 can separate the shaking chamber 31 and the dispersion chamber 32, so as to prevent the corundum from entering the shaking chamber 31 due to the shaking of the shaking box 30 and being retained, thereby ensuring the normal operation of the shaking box 30 and reducing the waste of corundum.

[0033] During the movement of the moving box 20, the adjusting plate 24 on the side away from the moving direction of the moving box 20 selects the limiting hole 26 at the appropriate position, so that the end of the trowel plate 23 away from the adjusting plate 24 abuts against the concrete surface, and the limiting pin 27 is inserted to fix it, and then the tightening nut 29 is rotated to increase the abutting pressure between the tightening nut 29 and the adjusting plate 24. At this time, the trowel plate 23 cannot be turned freely, and the adjusting plate 24 on the side facing the moving direction of the moving box 20 selects the limiting hole 26 at the appropriate position so that the trowel plate 23 cannot contact the cement surface. Through the above movement process, the trowel plate 23 can press the corundum scattered on the concrete surface into the concrete, so that the corundum is fully in contact with the concrete. At the same time, the trowel plate 23 can perform a trowel treatment on the concrete surface. Compared with the traditional troweling method of manually entering the floor with a trowel machine, this can avoid the influence of people on the floor, which is conducive to improving the flatness of the floor.
