Description

Technical Field

[0001] The invention relates to the technical field of paving, in particular to paving equipment with a mortar overflow prevention function. Background Art

[0002] In construction, mortar paving is an important part of the construction of infrastructure such as platforms and floors. Traditional mortar paving mainly relies on manual operation, which has problems such as low efficiency, poor precision, and high labor intensity. With the development of automation technology, mortar paving machines are gradually introduced into construction sites to improve construction efficiency and paving quality.

[0003] However, the existing mortar paving machines still have some problems in practical applications. For example, before mortar paving, construction workers usually set anti-overflow components on both sides of the area to be paved, but the existing mortar paving machines lack effective positioning and correction mechanisms, which makes it difficult to accurately control the distance between the anti-overflow components and the edge of the platform. If the base plate laying position is inaccurate, the mortar edge may not be parallel to the platform edge during subsequent mortar paving, affecting the overall construction quality; finally, during the mortar paving process, mortar often overflows from the side ends of the leveling components for various reasons. The existing equipment lacks an effective collection and cleaning mechanism, which causes the overflowed mortar to often solidify on the back of the anti-overflow component, which not only affects the appearance, but may also hinder subsequent construction. Summary of the Invention

[0004] The purpose of the present invention is to provide a paving device with a mortar overflow prevention function to solve the problems raised in the prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a paving device with a mortar overflow prevention function, the paving device includes a base plate, a back plate and a paving mechanism. Before the present invention works, the base plate needs to be laid on the side of the platform first, and the distance from the base plate to the edge of the platform is set by the construction personnel according to needs. Compared with the current paving equipment, the present invention is provided with a positioning component and a collecting component on the paving mechanism. After the base plate is laid on the side of the platform, the base plate is positioned by the positioning component to ensure that the distance from the base plate to the edge of the platform is correct, to prevent the base plate from deviating. When the base plate is in the correct position, Construction workers can fix the bottom plate to the platform by manual drilling and welding, and then fix the back plate to the bottom plate with mechanical bolts (the height of the back plate is adjusted according to on-site needs and welded after adjustment). When ready, construction workers can transport mortar to the platform, and then move the paving mechanism to prevent mortar overflow through the bottom plate and back plate, and spread and level the mortar through the paving mechanism. When the paving mechanism is working, it collects mortar that accidentally overflows during the work process through the collection component, and cleans the back plate to prevent the mortar from solidifying on the side of the back plate close to the platform edge after paving is completed.

[0006] Furthermore, the paving mechanism includes a frame, a motor, a mounting frame and a transmission seat. The mounting frame is provided with two groups. The two groups of mounting frames are relatively arranged on both sides of the platform. A group of rollers is provided under each group of mounting frames. A spiral roller, a first leveling roller and a second leveling roller are provided between the two groups of mounting frames. When the direction of machine travel is positive, the spiral roller is located at the front, the first leveling roller is located behind the spiral roller, and the second leveling roller is located behind the first leveling roller. The frame is arranged above the two groups of mounting frames, and the motor is arranged on the frame. The motor is provided through the belt The belt and the transmission seat are connected to the roller, the motor is connected to the first leveling roller through a belt, the first leveling roller is connected to the spiral roller and the second leveling roller through a belt. When the paving mechanism in the present invention is working, the motor will drive the roller under the mounting frame, as well as the spiral roller, the first leveling roller, and the second leveling roller selection (the functions realized by the motor belong to conventional technical means in this field, and the specific structure is not described). The paving mechanism is moved along the base plate through the roller, the mortar is struck and vibrated by the spiral roller, and the mortar is leveled by the first leveling roller and the second leveling roller.

[0007] Furthermore, two groups of positioning components are provided under each group of mounting frames, and the two groups of positioning components are relatively arranged at the front and rear ends of the mounting frames, and the positioning components include a first cylinder, a lifting seat, a fixed seat and a positioning block. The first cylinder is arranged on the mounting frame, the lifting seat is arranged below the first cylinder, the fixed seat is arranged below the lifting seat, a linear moving module is arranged in the lifting seat, the fixed seat is connected to the working end of the linear moving module, the positioning block is arranged on the side of the fixed seat close to the base plate, and a third cylinder is provided on the side of the fixed seat away from the base plate, and the third cylinder is connected to the positioning block.

[0008] Furthermore, a baffle is provided under the fixed seat, and a sensing component is provided at one end of the positioning block away from the third cylinder. When the base plate is laid on the side of the platform and the position of the base plate needs to be positioned and detected, the construction personnel can start the first cylinder to make the baffle drop to a position aligned with the edge of the platform, and then start the lifting seat to make the baffle fit the edge of the platform through the lifting seat. At this time, the construction personnel can start the third cylinder, and use the third cylinder to make the distance between the end face of the positioning block away from the edge of the platform and the end face of the baffle fit the edge of the platform, which is equal to the distance from the base plate to the edge of the platform required by the construction personnel. If the base plate does not deviate, the two sets of positioning blocks under the mounting frame will both fit with the base plate. If the base plate deviates, at least one set of positioning blocks will not fit with the base plate. The present invention detects whether the base plate is aligned with the positioning block through the sensing component, thereby indirectly judging whether the base plate deviates after laying and whether the position is correct, thereby avoiding the mortar edge being not parallel to the platform edge during subsequent mortar paving.

[0009] Furthermore, the sensing component includes a sensing groove, a sensing spring and a sensing block. The sensing groove is arranged at the end of the positioning block away from the third cylinder, and the sensing block is arranged in the sensing groove. The sensing block and the sensing groove are connected by a sensing spring (the sensing spring is a high-sensitivity spring). A piezoelectric piece is provided at the end of the sensing block close to the sensing spring. When the positioning component in the present invention is not working, one end of the sensing block extends out of the sensing groove. When the positioning component is working, if the positioning block is in contact with the base plate, the sensing block will shrink into the sensing groove, and at the same time, the sensing spring will deform, causing the piezoelectric piece to generate a set of electrical signals. If the positioning block is not in contact with the base plate, the sensing block will not shrink into the sensing groove (or will not shrink completely into the sensing groove). At this time, the construction personnel can determine whether the base plate is offset and whether the position is correct by detecting the changes in the electrical signal output by the piezoelectric piece.

[0010] Furthermore, a fourth electromagnet is provided at the end of the positioning block away from the third cylinder. When it is detected that the position of the base plate is incorrect, the construction personnel can turn on the two groups of fourth electromagnets under the mounting frame. At this time, the two groups of fourth electromagnets will respectively generate a group of magnetic fields to attract the base plate, so that the base plate and the two groups of positioning blocks fit tightly together. According to the principle of "two points determine a straight line", as long as the distance between the end faces of the two groups of positioning blocks away from the edge of the platform and the edge of the platform is equal to the distance from the base plate to the edge of the platform required by the construction personnel, the position of the base plate can be restored to the correct position. Through the above technical solution, the present invention can timely correct the posture of the offset base plate to avoid affecting the subsequent mortar paving.

[0011] Furthermore, the collecting assembly includes a second cylinder and an aggregate box, the second cylinder is arranged on the mounting frame and is located between the spiral roller and the first leveling roller, the aggregate box is arranged below the second cylinder, and an opening is provided at one end of the aggregate box close to the back plate, and the bottom end of the opening is in contact with the back plate. When the paving mechanism in the present invention is paving mortar, sometimes the mortar overflows from the side of the first leveling roller close to the spiral roller due to excessive mortar. At this time, the construction personnel can turn on the second cylinder and control the aggregate box to perform reciprocating lifting and lowering motion along the back plate through the second cylinder (the opening of the aggregate box is always in contact with the back plate). On the one hand, the overflowed mortar is collected through the aggregate box, and on the other hand, the back plate can be cleaned by the aggregate box opening to prevent the overflowed mortar from solidifying at the position of the back plate close to the edge of the platform.

[0012] Furthermore, a linkage assembly is provided inside the transmission seat, and the connection between the motor and the roller is controlled by the linkage assembly.

[0013] Furthermore, the linkage assembly includes an output shaft, an input shaft, a first linkage block and a second linkage block, the first linkage block is arranged on the output shaft, the second linkage block is arranged on the input shaft, the output shaft is connected to the roller through a belt, and the input shaft is connected to the motor through a belt, the first linkage block is provided with a transmission block and a magnetic block at one end close to the second linkage block, the second linkage block is provided with a transmission groove and a third electromagnet at one end close to the first linkage block, and the first linkage block is also provided with a second electromagnet at one end away from the second linkage block, the movement of the transmission block is controlled by the second electromagnet, and the transmission block is adapted to the transmission groove.

[0014] When the paving mechanism of the present invention is paving mortar, the transmission block is located in the transmission groove, the second electromagnet will generate a set of magnetic fields that repel the transmission block, and the third electromagnet will generate a set of magnetic fields that attract the magnetic block. Through the transmission block and the transmission groove, and the suction force of the third electromagnet on the magnetic block, the first linkage block and the second linkage block are linked together. When the paving mechanism finishes paving the mortar, the construction personnel can turn off the third electromagnet and change the magnetic field generated by the second electromagnet so that the second electromagnet attracts the transmission block. At this time, the transmission block will extend from the transmission groove, and the third electromagnet will no longer generate suction force on the magnetic block. When the motor is working, the motor will only drive the spiral roller, the first leveling roller, and the second leveling roller to rotate, but will not drive the roller to rotate. At this time, the spiral roller, the first leveling roller, and the second leveling roller can be rotated. The mortar attached to the surface of the leveling roller is thrown away to prevent the mortar attached to the surface of the spiral roller, the first leveling roller and the second leveling roller from dripping everywhere when the subsequent paving mechanism moves to other areas. When the construction personnel need to link the first linkage block and the second linkage block together later, they only need to turn on the third electromagnet first, and then drive the second linkage block to rotate through the motor. At this time, after the third electromagnet is aligned with the magnetic block, the first linkage block and the second linkage block will be preliminarily linked together. Then the construction personnel can turn on the second electromagnet and generate a set of magnetic fields that repel the transmission block through the second electromagnet, so that the transmission block can be inserted into the transmission slot. Compared with the currently used magnetic linkage method, the third electromagnet in the present invention plays a role of preliminary linkage with the magnetic block on the one hand, and plays a role of positioning on the other hand, thereby facilitating the insertion of the transmission block into the transmission slot to overcome the problem of too small magnetic linkage load.

[0015] Furthermore, a base is provided under the frame, and two groups of grooves are provided inside the base, and the two groups of grooves are aligned with the first leveling roller and the second leveling roller respectively. A group of scrapers is provided at the lower end of the inner part of each group of grooves, and a group of first electromagnets is provided at the upper end of the inner part of each group of grooves. The scrapers are controlled to move in the grooves by the first electromagnets. When the first leveling roller and the second leveling roller in the present invention are leveling the mortar, the first electromagnets in each group of grooves will control the scrapers above the first leveling roller and the second leveling roller to contact the first leveling roller and the second leveling roller. The two groups of scrapers can prevent effective mortar from adhering to the surfaces of the first leveling roller and the second leveling roller, thereby preventing the mortar from dripping into the area that has just been leveled.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: compared with the current paving equipment, the present invention is provided with a positioning component. After the base plate is laid on the side of the platform, the base plate is positioned by the positioning component to detect whether the distance from the base plate to the edge of the platform is correct. When it is detected that the laying position of the base plate is incorrect, the two sets of fourth electromagnets under the mounting frame can make the base plate fit tightly with the two sets of positioning blocks, thereby correcting the posture of the offset base plate to avoid the subsequent mortar paving, due to the incorrect position of the base plate, resulting in the mortar edge and the platform edge being not parallel. The present invention is also provided with a collecting component. When the paving mechanism is paving the mortar, the collecting component can collect the overflowed mortar on the one hand, and on the other hand, the collecting component can clean the back plate to prevent the overflowed mortar from solidifying at the position where the back plate is close to the edge of the platform. The present invention is also provided with a coupling inside the transmission seat. The driving component controls whether the motor and the roller are in a connected state through the linkage component. When the paving mechanism finishes paving the mortar, the construction personnel can disconnect the connection between the motor and the roller through the linkage component. At this time, when the motor is working, the motor will only drive the spiral roller, the first leveling roller, and the second leveling roller to rotate, and will not drive the roller to rotate. The mortar attached to the surface of the spiral roller, the first leveling roller, and the second leveling roller can be thrown away through the rotation of the spiral roller, the first leveling roller, and the second leveling roller, so as to avoid the mortar attached to the surface of the spiral roller, the first leveling roller, and the second leveling roller from dripping everywhere when the subsequent paving mechanism moves to other areas. Finally, the present invention is also provided with a scraper. When the first leveling roller and the second leveling roller are leveling the mortar, the scraper can prevent the effective mortar from adhering to the surface of the first leveling roller and the second leveling roller, thereby preventing the mortar from dripping into the area that has just been leveled.

DETAILED DESCRIPTION

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] Example: Figures 1-12As shown, the present invention provides a technical solution, a paving device with a mortar overflow prevention function, the paving device includes a base plate 1, a back plate 2 and a paving mechanism 3. Before the present invention works, the base plate 1 needs to be laid on the side of the platform first, and the distance from the base plate 1 to the edge of the platform is set by the construction personnel according to the needs. Compared with the current paving equipment, the present invention is provided with a positioning component 38 and a collecting component on the paving mechanism 3. After the base plate 1 is laid on the side of the platform, the base plate 1 is positioned by the positioning component 38 to ensure that the distance from the base plate 1 to the edge of the platform is correct, to prevent the base plate 1 from offsetting. When the position of the base plate 1 is correct, the construction Personnel can fix the bottom plate 1 on the platform by manual drilling and welding, and then fix the back plate 2 on the bottom plate 1 by mechanical bolts (the height of the back plate 2 is adjusted according to the needs of the site and welded after the adjustment). When ready, the construction personnel can transport mortar to the platform, and then move the paving mechanism 3 to prevent the mortar from overflowing through the bottom plate 1 and the back plate 2. The mortar is spread and leveled through the paving mechanism 3. When the paving mechanism 3 is working, the mortar that accidentally overflows during the work process is collected through the collecting component, and the back plate 2 is cleaned to prevent the mortar from solidifying on the side of the back plate 2 close to the platform edge after the paving is completed.

[0021] like Figure 1-Figure 4 As shown, the paving mechanism 3 includes a frame 31, a motor 32, a mounting frame 33 and a transmission seat 34. There are two groups of mounting frames 33. The two groups of mounting frames 33 are relatively arranged on both sides of the platform. A group of rollers are arranged under each group of mounting frames 33. A spiral roller 35, a first leveling roller 36 and a second leveling roller 37 are arranged between the two groups of mounting frames 33. According to the direction of machine travel as the positive direction, the spiral roller 35 is located at the front, the first leveling roller 36 is located behind the spiral roller 35, and the second leveling roller 37 is located behind the first leveling roller 36. The frame 31 is arranged above the two groups of mounting frames 33, and the motor 32 is arranged on the frame 31. The motor 32 is rotated by The belt and the transmission seat 34 are connected to the roller, the motor 32 is connected to the first leveling roller 36 through the belt, and the first leveling roller 36 is connected to the spiral roller 35 and the second leveling roller 37 through the belt. When the paving mechanism 3 in the present invention is working, the motor 32 will drive the roller under the mounting frame 33, as well as the spiral roller 35, the first leveling roller 36, and the second leveling roller 37 to be selected (the function realized by the motor 32 belongs to the conventional technical means in this field, and the specific structure is not described). The roller is used to move the paving mechanism 3 along the base plate 1, the spiral roller 35 is used to hit and vibrate the mortar, and the first leveling roller 36 and the second leveling roller 37 are used to level the mortar.

[0022] like Figure 4-Figure 6As shown, two groups of positioning assemblies 38 are provided under each group of mounting frames 33, and the two groups of positioning assemblies 38 are relatively arranged at the front and rear ends of the mounting frames 33. The positioning assemblies 38 include a first cylinder 381, a lifting seat 382, a fixed seat 383 and a positioning block 384. The first cylinder 381 is arranged on the mounting frame 33, the lifting seat 382 is arranged below the first cylinder 381, the fixed seat 383 is arranged below the lifting seat 382, a linear motion module is provided in the lifting seat 382, the fixed seat 383 is connected to the working end of the linear motion module, the positioning block 384 is provided on the side of the fixed seat 383 close to the base plate 1, and a third cylinder 3831 is provided on the side of the fixed seat 383 away from the base plate 1, and the third cylinder 3831 is connected to the positioning block 384.

[0023] like Figure 5-Figure 6 As shown, a baffle 3832 is provided below the fixing seat 383, and a sensing component is provided at one end of the positioning block 384 away from the third cylinder 3831, through which the sensing component detects whether the position of the bottom plate 1 is correct.

[0024] When the base plate 1 is laid on the side of the platform and the position of the base plate 1 needs to be positioned and detected, the construction personnel can start the first cylinder 381 to make the baffle 3832 drop to a position aligned with the edge of the platform, and then start the lifting seat 382 to make the baffle 3832 fit the edge of the platform through the lifting seat 382. At this time, the construction personnel can start the third cylinder 3831 to make the positioning block 384 move away from the end face of the platform edge and the baffle 3832 fit the end face of the platform edge. The distance between them is equal to the distance from the base plate 1 to the edge of the platform required by the construction workers. If the base plate 1 has not deviated, the two groups of positioning blocks 384 under the mounting frame 33 will both fit with the base plate 1. If the base plate 1 has deviated, at least one group of positioning blocks 384 will not fit with the base plate 1. The present invention detects whether the base plate 1 is aligned with the positioning blocks 384 through a sensing component, thereby indirectly judging whether the base plate 1 has deviated after laying and whether the position is correct, so as to avoid the mortar edge being non-parallel to the platform edge during subsequent mortar paving.

[0025] like Figure 6As shown, the sensing assembly includes a sensing groove, a sensing spring and a sensing block 3842. The sensing groove is arranged at the end of the positioning block 384 away from the third cylinder 3831, and the sensing block 3842 is arranged in the sensing groove. The sensing block 3842 and the sensing groove are connected by an sensing spring (the sensing spring is a high-sensitivity spring). A piezoelectric piece is arranged at the end of the sensing block 3842 close to the sensing spring. When the positioning assembly 38 of the present invention is not working, one end of the sensing block 3842 extends out of the sensing groove. When the positioning assembly 38 is working, if the positioning block 384 is in contact with the base plate 1, the sensing block 3842 will retract into the sensing groove, and at the same time, the sensing spring will deform, causing the piezoelectric piece to generate a set of electrical signals. If the positioning block 384 is not in contact with the base plate 1, the sensing block 3842 will not retract into the sensing groove (or will not completely retract into the sensing groove). At this time, the construction personnel can determine whether the base plate 1 is offset and whether the position is correct by detecting the changes in the electrical signal output by the piezoelectric piece.

[0026] like Figure 6 As shown, a fourth electromagnet 3841 is further provided at one end of the positioning block 384 away from the third cylinder 3831. When it is detected that the laying position of the base plate 1 is incorrect, the construction personnel can turn on the two groups of fourth electromagnets 3841 under the mounting bracket 33. At this time, the two groups of fourth electromagnets 3841 will respectively generate a group of magnetic fields to attract the base plate 1, so that the base plate 1 and the two groups of positioning blocks 384 fit tightly together. According to the principle of "two points determine a straight line", as long as the distance between the end faces of the two groups of positioning blocks 384 away from the edge of the platform and the edge of the platform is equal to the distance from the base plate 1 to the edge of the platform required by the construction personnel, the position of the base plate 1 can be restored to the correct position. Through the above technical solution, the present invention can timely correct the posture of the offset base plate 1 to avoid affecting the subsequent mortar paving.

[0027] like Figure 2 、 Figure 3 、 Figure 7 As shown, the collecting assembly includes a second cylinder 39 and a collection box 391. The second cylinder 39 is arranged on the mounting frame 33 and is located between the spiral roller 35 and the first leveling roller 36. The collection box 391 is arranged below the second cylinder 39. The collection box 391 is provided with an opening at one end close to the backboard 2, and the bottom end of the opening is in contact with the backboard 2. When the paving mechanism 3 in the present invention is paving the mortar, sometimes the mortar overflows from the side of the first leveling roller 36 close to the spiral roller 35 due to excessive mortar. At this time, the construction personnel can turn on the second cylinder 39 and control the collection box 391 to make reciprocating lifting and lowering movements along the backboard 2 through the second cylinder 39 (the opening of the collection box 391 is always in contact with the backboard 2). On the one hand, the overflowed mortar is collected by the collection box 391, and on the other hand, the opening of the collection box 391 can clean the backboard 2 to prevent the overflowed mortar from solidifying at the position of the backboard 2 near the edge of the platform.

[0028] like Figure 2 、 Figure 10-12 As shown, a linkage assembly is provided inside the transmission seat 34, and the connection between the motor 32 and the roller is controlled by the linkage assembly.

[0029] like Figure 10-12 As shown, the linkage assembly includes an output shaft 341, an input shaft 342, a first linkage block 343 and a second linkage block 344. The first linkage block 343 is arranged on the output shaft 341, and the second linkage block 344 is arranged on the input shaft 342. The output shaft 341 is connected to the roller through a belt, and the input shaft 342 is connected to the motor 32 through a belt. The first linkage block 343 is close to the second linkage block 344 and is provided with a transmission block 3432 and a magnetic block 3433. The second linkage block 344 is close to the first linkage block 343 and is provided with a transmission groove 3441 and a third electromagnet 3442. The first linkage block 343 is further provided with a second electromagnet 3431 at the end away from the second linkage block 344. The movement of the transmission block 3432 is controlled by the second electromagnet 3431, and the transmission block 3432 is adapted to the transmission groove 3441.

[0030] When the paving mechanism 3 of the present invention is paving the mortar, the transmission block 3432 is located in the transmission groove 3441, the second electromagnet 3431 generates a set of magnetic fields that repel the transmission block 3432, and the third electromagnet 3442 generates a set of magnetic fields that attract the magnetic block 3433. Through the transmission block 3432 and the transmission groove 3441, and the suction force of the third electromagnet 3442 on the magnetic block 3433, the first linkage block 343 and the second linkage block 344 are linked together. When the paving mechanism 3 finishes paving the mortar, the construction personnel can turn off the third electromagnet. 3442, and changes the magnetic field generated by the second electromagnet 3431, so that the second electromagnet 3431 attracts the transmission block 3432, and the transmission block 3432 will extend from the transmission slot 3441. At the same time, the third electromagnet 3442 no longer generates suction on the magnetic block 3433. When the motor 32 is working, the motor 32 will only drive the spiral roller 35, the first flattening roller 36, and the second flattening roller 37 to rotate, and will not drive the roller to rotate. At this time, the spiral roller 35, the first flattening roller 36, and the second flattening roller 37 can be rotated. The mortar attached to the surface of the first leveling roller 36 and the second leveling roller 37 is thrown away to prevent the mortar attached to the surface of the spiral roller 35, the first leveling roller 36 and the second leveling roller 37 from dripping everywhere when the paving mechanism 3 is subsequently moved to other areas. When the construction personnel need to link the first linkage block 343 and the second linkage block 344 together later, they only need to turn on the third electromagnet 3442 first, and then drive the second linkage block 344 to rotate through the motor 32. At this time, after the third electromagnet 3442 is aligned with the magnetic block 3433, the first linkage block 343 and the second linkage block 344 are connected. The moving block 344 will first be preliminarily linked together, and then the construction personnel can turn on the second electromagnet 3431, and generate a set of magnetic fields that repel the transmission block 3432 through the second electromagnet 3431, so that the transmission block 3432 can be inserted into the transmission slot 3441. Compared with the currently used magnetic linkage method, the third electromagnet 3442 in the present invention plays a role of preliminary linkage with the magnetic block 3433 on the one hand, and plays a role of positioning on the other hand, thereby facilitating the insertion of the transmission block 3432 into the transmission slot 3441, so as to overcome the problem of too small magnetic linkage load.

[0031] like Figure 8-Figure 9As shown, a base 311 is also provided under the frame 31, and two groups of grooves are provided inside the base 311, and the two groups of grooves are aligned with the first leveling roller 36 and the second leveling roller 37 respectively. A group of scrapers 313 is provided at the lower end of the inner part of each group of grooves, and a group of first electromagnets 312 is provided at the upper end of the inner part of each group of grooves. The scrapers 313 are controlled to move in the grooves by the first electromagnets 312. When the first leveling rollers 36 and the second leveling rollers 37 in the present invention are leveling the mortar, the first electromagnets 312 in each group of grooves will control the scrapers 313 above the first leveling rollers 36 and the second leveling rollers 37 to contact the first leveling rollers 36 and the second leveling rollers 37. The two groups of scrapers 313 can prevent effective mortar from adhering to the surfaces of the first leveling rollers 36 and the second leveling rollers 37, thereby preventing the mortar from dripping into the area that has just been leveled.

[0032] The working principle of the present invention is as follows: before work, the base plate 1 is first laid on the side of the platform, and then the base plate 1 is positioned by the positioning component 38: when it is detected that the laying position of the base plate 1 is incorrect, the two groups of fourth electromagnets 3841 under the mounting frame 33 are turned on to make the base plate 1 fit tightly with the two groups of positioning blocks 384, thereby correcting the posture of the offset base plate 1. When the position of the base plate 1 is correct, the base plate 1 is fixed to the platform by manual drilling and welding, and then the back plate 2 is fixed to the base plate 1 by mechanical bolts. After preparation, the construction personnel can transport mortar to the platform, and then move the paving mechanism 3 to prevent the mortar from overflowing through the base plate 1 and the back plate 2. The mortar is spread and leveled through the paving mechanism 3. When the paving mechanism 3 is working, the mortar that accidentally overflows during the work process is collected by the collecting component, and the back plate 2 is cleaned to prevent the mortar from solidifying on the side of the back plate 2 close to the platform edge after the paving is completed.

[0033] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the invention can be embodied in other specific forms without departing from the spirit or essential characteristics of the invention. The embodiments should therefore be considered illustrative and non-restrictive, and the scope of the invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed therein. Any reference sign in a claim should not be construed as limiting the claim to which it relates.
