Description

Technical Field

[0001] The invention relates to the technical field of wall plastering, in particular to a plastering device with an adjusting function. Background Art

[0002] A plastering device is a device used to apply mortar or putty to surfaces such as walls and ceilings during construction. This device can greatly improve work efficiency and ensure the quality and uniformity of the plastering.

[0003] The actual plastering device usually uses an electric slider in conjunction with a track to drive the moving block and the trapezoidal basket that holds the mortar to move upward, so that the mortar in the trapezoidal basket is applied to the wall by the action of the trapezoidal basket and the moving block. When the trapezoidal basket moves to the highest position, it is pressed down by the ceiling and retracted into the receiving groove of the moving block. Then, the electric slider is used to cooperate with the track again to move the moving block and the trapezoidal basket that holds the mortar downward and smooth the mortar again.

[0004] Although the above-mentioned automatic plastering device can efficiently plaster the wall, when the trapezoidal basket moves to the highest position and is retracted into the receiving groove of the moving block due to the downward pressure of the ceiling above, more mortar adheres to the bottom of the trapezoidal basket, resulting in insufficient amount of mortar poured on the top of the wall, causing the mortar to become concave after a period of time after plastering, making it impossible to guarantee the coating quality; in addition, since the above-mentioned device needs to continuously adjust the position of the device for coating when plastering the wall, joints will be generated in the adjacent plastering processes, and the above-mentioned device cannot ensure the flatness and quality of the mortar joints, which leads to the overall low quality of the mortar after the plastering is completed.

[0031] The following embodiments of the present invention are described in detail. The embodiments described below are exemplary and are only used to explain the present invention, and are not to be construed as limiting the present invention. Where specific techniques or conditions are not specified in the embodiments, the techniques or conditions described in the literature in the art or in the product specifications shall be followed.

[0032] See Figure 1-Figure 2 A plastering device with an adjustment function includes a horizontal slide rail 1, horizontal support plates 11 are symmetrically fixed on the left and right ends of the horizontal slide rail 1, a collecting plate 2 is connected to the horizontal slide rail 1 through a horizontal electric slider, vertical slide rails 21 are symmetrically fixed to the top of the collecting plate 2, and the two vertical slide rails 21 are connected to a receiving frame 22 through a vertical electric slider. A mortar storage mechanism 3 is arranged in the receiving frame 22, and anti-leakage mechanisms 4 are symmetrically arranged on the left and right sides of the receiving frame 22, and a joint smoothing mechanism 5 is arranged on the anti-leakage mechanism 4 on the right.

[0033] In this embodiment, if Figure 1 and Figure 2As shown, in order to further fix the position of the horizontal slide rail 1, a positioning hole needs to be preset on the front side of the plastered wall, and a matching hole is opened on the horizontal support plate 11. Positioning nails are connected to the positioning hole and the matching hole.

[0034] The present invention uses the leak-proof mechanism 4 to block the mortar stored in the mortar storage mechanism 3, thereby preventing the mortar in the mortar storage mechanism 3 from falling, thereby eliminating the step of cleaning the fallen mortar. At the same time, the joint smoothing mechanism 5 is used to fill and further smooth the joint positions generated after each plastering is completed, thereby ensuring that the mortar joints after the plastering are smooth, thereby reducing the workload of subsequent repeated smoothing of the mortar joints after the plastering is completed.

[0035] Specifically, first, the horizontal support plate 11 is positioned and installed through the positioning holes, matching holes and positioning pins to ensure the overall stability of the device. Then the operator loads the mixed mortar into the mortar storage mechanism 3. At this time, the mortar storage mechanism 3 is against the front side of the wall at the rear side. Then, the vertical electric slider is controlled to drive the collecting plate 2, the containing frame 22 and the mortar storage mechanism 3 to move upward synchronously. During this process, the mortar in the mortar storage mechanism 3 will be evenly applied to the wall, and the containing frame 22 will initially smooth the mortar. At the same time, the leak-proof mechanism 4 will block the mortar that is about to fall and return it to the mortar storage mechanism 3. Then, the horizontal electric slider is controlled to drive the collecting plate 2, the containing frame 22 and the mortar storage mechanism 3 to move to the left, and then the above-mentioned plastering operation is repeated. In the subsequent plastering operation, the joint smoothing mechanism 5 will smooth the joints between the two sections of mortar, thereby making the overall plastering effect of the wall better.

[0036] See Figure 2-Figure 4 The mortar storage mechanism 3 includes a trapezoidal basket 31 hinged in the accommodating frame 22, and openings are provided on the rear sides of the trapezoidal basket 31 and the accommodating frame 22, and a locking member 32 is provided between the front side of the trapezoidal basket 31 and the accommodating frame 22, and a rear support structure is provided on the rear side of the bottom of the trapezoidal basket 31, and a pushing member 33 is provided in the trapezoidal basket 31 for cooperating with the inner wall of the accommodating frame 22 to push the remaining mortar in the trapezoidal basket 31; a U-shaped support plate 211 is fixed to the top of the two vertical slide rails 21, and an unlocking block 212 for cooperating with the locking member 32 is fixed to the bottom of the horizontal section of the U-shaped support plate 211; the rear support structure includes a accommodating groove 311 opened at the rear end of the bottom of the trapezoidal basket 31, and a rear support plate 312 is connected to the accommodating groove 311 through multiple internal springs, and the rear support plate 312 can continuously close the bottom of the trapezoidal basket 31.

[0037] The mortar storage mechanism 3 is used to store mortar, so that the mortar can be evenly applied to the wall surface during the upward movement of the collecting plate 2, the containing frame 22 and the mortar storage mechanism 3. At the same time, the locking member 32 and the pushing member 33 cooperate with each other, and when the mortar storage mechanism 3 reaches the top of the wall, it is pressed by the unlocking block 212 at the top to lower the trapezoidal basket 31 in advance, so that the mortar stored in the trapezoidal basket 31 is fully poured out and applied to the wall surface. The rear support structure can ensure that the lower side of the trapezoidal basket 31 is closed regardless of the rotation angle of the trapezoidal basket 31, thereby preventing the mortar from falling, and at the same time can cooperate with the bottom of the containing frame 22 to smooth the mortar, thereby increasing the smoothing effect of the mortar.

[0038] See Figure 3 、 Figure 4 and Figure 7 The locking member 32 includes a positioning sleeve 321 fixed to the front side wall of the accommodating frame 22, and a locking rod 322 is slidably connected in the positioning sleeve 321. An L-shaped fixing plate 323 is fixed to the front side of the accommodating frame 22, and a longitudinal spring is connected between the vertical section of the L-shaped fixing plate 323 and the locking rod 322. A coordinating triangular block 324 pushed by the unlocking block 212 is fixed to the top of the locking rod 322 and located in front of the positioning sleeve 321; a blocked plate 325 is fixed to the bottom of the rear side of the trapezoidal basket 31, and the blocked plate 325 is blocked by the rear end of the locking rod 322 so that the trapezoidal basket 31 is always in a tilted state.

[0039] The locking member 32 is used to lock the position of the trapezoidal basket 31, so that the trapezoidal basket 31 is always in an inclined state, thereby facilitating the mortar stored in the trapezoidal basket 31 to be fully poured onto the wall surface, and by coordinating the triangular block 324 and the unlocking block 212, the inclined state of the trapezoidal basket 31 can be unlocked in advance before the trapezoidal basket 31 moves to the top, thereby facilitating the pushing member 33 to push the remaining mortar in the trapezoidal basket 31 to the wall surface and ensure the mortar leveling effect on the top of the wall.

[0040] Specifically, after the overall stability of the device is achieved through the positioning holes, matching holes and positioning pins, the operator puts the mixed mortar into the trapezoidal basket 31. At this time, the rear support plate 312 on the rear side of the trapezoidal basket 31 will be pressed against the wall at the rear side. Then the vertical electric slider is controlled to drive the collecting plate 2, the containing frame 22 and the mortar storage mechanism 3 to move upward synchronously. The mortar in the trapezoidal basket 31 will be successively attached to the wall from the opening position on the rear side of the trapezoidal basket 31, and the mortar will be pressed and smoothed by the rear support plate 312, and then the mortar will be further smoothed through the bottom of the containing frame 22, so that the mortar is flat.

[0041] When the collecting plate 2, the containing frame 22 and the mortar storage mechanism 3 move upward to the top position, the coordinating triangle block 324 will be pushed by the unlocking block 212 and move backward, and drive the locking rod 322 to move backward, so that the locking rod 322 is separated from the blocked plate 325 and the blocking effect on the blocked plate 325 is released. The trapezoidal basket 31 will rotate downward due to its own gravity and the gravity of the remaining mortar inside it, and finally rotate to the bottom of the retaining frame 22. During this process, the pushing member 33 will push the remaining mortar in the trapezoidal basket 31 toward the wall, and further apply the mortar to the wall.

[0042] See Figure 4-Figure 7 The pushing member 33 includes two sliding rods 331 that slide through the front side of the trapezoidal basket 31. The front ends of the two sliding rods 331 are fixed with arc-shaped push rods 332. The top of the front end of the sliding rods 331 is fixed with an upper extension rod 333. An elastic telescopic rod is connected between the upper extension rod 333 and the front side of the trapezoidal basket 31. A horizontal shovel 334 is fixed on the two sliding rods 331 and located in the middle. The rear ends of the two sliding rods 331 are jointly provided with a rotating shovel structure; the rotating shovel structure includes a rotating shovel plate 335 hinged between the two sliding rods 331. Oblique track grooves 336 are symmetrically provided on the left and right inner walls of the trapezoidal basket 31. Track rods 337 are symmetrically fixed on the left and right sides of the rotating shovel plate 335 and at the positions corresponding to the oblique track grooves 336.

[0043] The pushing member 33 is used to push the remaining mortar in the trapezoidal basket 31 toward the wall when the trapezoidal basket 31 moves to the top, and to scoop up the remaining mortar and apply it to the wall by rotating the shoveling structure, thereby ensuring the mortar application effect on the top of the wall. In addition, due to the cooperation of the oblique track groove 336 and the track rod 337, the rotating shovel plate 335 can shovel the mortar while making the mortar applied to the wall smooth as the trapezoidal basket 31 rotates.

[0044] The mortar on the bottom of the trapezoidal basket 31 is moved backwards by the sliding rod 331. At the same time, the rotating shovel plate 335 also moves backwards synchronously. Due to the downward pressure of the track rod 337 by the inclined track groove 336, the rotating shovel plate 335 rotates to an inclined state and further pushes the mortar on the bottom of the trapezoidal basket 31 toward the wall. At the same time, since the trapezoidal basket 31 and the containing frame 22 are still in an ascending state, the rotating shovel plate 335 smoothes the mortar on the wall after rotating to a complete tilt.

[0045] See Figure 4 、 Figure 5 、 Figure 8 and Figure 9 The leakage prevention mechanism 4 includes a mounting block 41 fixed to the left or right side of the accommodating frame 22, an edge straightening member 42 is provided in the mounting block 41, an inward-retracting member 43 is provided on the top of the mounting block 41, and the seam smoothing mechanism 5 is connected to the inward-retracting member 43; the edge straightening member 42 includes a rear through groove 421 opened in the mounting block 41, and an edge straightening block 422 is slidably connected in the rear through groove 421. The side of the edge straightening block 422 close to the trapezoidal basket 31 is provided with an edge straightening slope, and a stud 423 is rotatably installed on the front side of the edge straightening block 422, and the stud 423 is threadedly connected to the mounting block 41.

[0046] The inward-retracting component 43 in the leak-proof mechanism 4 can push the mortar on the left and right sides that is easy to fall during the plastering process, thereby preventing the mortar from falling, and thus avoiding the subsequent multiple cleaning of the fallen mortar. At the same time, the edge-straightening component 42 can repair the mortar joint position, thereby facilitating the joint smoothing mechanism 5 to further smooth and repair the mortar joint position. At the same time, the position of the edge-straightening block 422 can be adjusted by the stud 423, and then in the process of the assembly plate 2, the receiving frame 22 and the mortar storage mechanism 3 moving to the left, the edge-straightening block 422 is prevented from damaging the mortar that has been applied, and the edge-straightening effect of the edge-straightening block 422 on the right can be revoked, thereby facilitating the subsequent mortar application work.

[0047] Specifically, when the horizontal electric slider is located on the far right and is applying mortar, first rotate the stud 423 to move the two whole edge blocks 422 backward and press them against the wall. Then control the vertical electric slider to drive the collecting plate 2, the receiving frame 22 and the mortar storage mechanism 3 to move upward synchronously. The whole edge blocks 422 will then trim the left and right edges of the applied mortar.

[0048] When the rightmost side of the wall is painted, first control the vertical electric slider to drive the collecting plate 2, the receiving frame 22 and the mortar storage mechanism 3 to move downward to the bottom synchronously, then control the stud 423 to rotate, and move the whole edge block 422 on the right side into the rear through groove 421, and then control the horizontal electric slider to drive the collecting plate 2, the receiving frame 22 and the mortar storage mechanism 3 to move to the left, and repeat the above plastering steps.

[0049] Continue reading Figure 4 、 Figure 5 and Figure 8The inward-retracting component 43 includes an inward-retracting plate 431 hinged at the top of the mounting block 41, and a square plate 432 is fixed to the side of the mounting block 41 away from the trapezoidal basket 31. The angle between the inward-retracting plate 431 and the square plate 432 is greater than 60°, and a connecting spring is connected between the inward-retracting plate 431 and the square plate 432. A transmission rod 433 is fixed to the front side of the inward-retracting plate 431; intermittent pushing structures for pushing the transmission rod 433 are symmetrically arranged on the left and right sides of the collecting plate 2, and the transmission rod 433 is pushed by the intermittent pushing structure and the mortar that is about to fall is pushed back into the trapezoidal basket 31; the intermittent pushing structure includes L-shaped mounting plates 23 symmetrically fixed on the left and right sides of the collecting plate 2, and the vertical section of each L-shaped mounting plate 23 is vertically and linearly fixed with a plurality of semicircular protrusions 231 for pushing the transmission rod 433.

[0050] The retraction member 43 is used to push the mortar that is about to fall during the mortar application process inward and retract it into the trapezoidal basket 31, thereby preventing the mortar from falling from the left and right sides during the mortar application process, thereby eliminating the step of cleaning the fallen mortar, and through the pressure of the semicircular protrusion 231 on the transmission rod 433, the retraction plate 431 can frequently retract the mortar into the trapezoidal basket 31, ensuring the utilization rate of the mortar.

[0051] Specifically, when the vertical electric slider drives the collecting plate 2, the containing frame 22 and the mortar storage mechanism 3 to move upward synchronously, the inner retracting plate 431 will also move upward synchronously. When the transmission rod 433 moves upward until it contacts the semicircular protrusion 231, since the angle between the inner retracting plate 431 and the square plate 432 is greater than 60°, the semicircular protrusion 231 will push the transmission rod 433 toward the collecting plate 2, thereby causing the inner retracting plate 431 to rotate toward the collecting plate 2, and causing the mortar accumulated at the position of the inner retracting plate 431 to be pushed back into the trapezoidal basket 31 again.

[0052] It should be noted that, since the mortar that is about to fall is located in front of the mortar that has been applied and falls out of the receiving frame 22, the retracting plate 431 will not damage the mortar that has been applied when pushing back the mortar that is about to fall.

[0053] See Figure 5 、 Figure 8 、 Figure 9 and Figure 10The joint smoothing mechanism 5 includes a square limiting sleeve 51 fixed to the front side of the inner retracting plate 431 on the right side, a longitudinal slide rod 511 is slidably connected in the square limiting sleeve 51, a vertical plate 512 is fixed to the front end of the longitudinal slide rod 511, a compression spring 513 is connected between the vertical plate 512 and the square limiting sleeve 51, and a rotating smoothing member 52 is jointly provided on the rear end of the longitudinal slide rod 511 and the inner retracting plate 431; the position of the top of the accommodating frame 22 and corresponding to the vertical plate 512 A forward push block 221 is fixed, and a coordination rod 514 that cooperates with the forward push block 221 is fixed on the vertical plate 512; the rotating smoothing component 52 includes a rotating trowel plate 521 hinged at the rear end of the longitudinal slide bar 511, and an extension sleeve 522 is fixed at the hinge position of the rotating trowel plate 521, and a toothed protrusion 523 is fixed at the end of the extension sleeve 522 away from the rotating trowel plate 521, and a rack 524 that meshes with the toothed protrusion 523 is fixed on the upper side of the retracting plate 431.

[0054] The joint smoothing mechanism 5 is used to smooth the joint positions of the two sections of mortar on the right side, so that the applied mortar is overall flat and ensures the overall effect of the plastering. At the same time, the toothed protrusion 523 can cooperate with the rack 524 to drive the rotating trowel plate 521 to rotate, so that when the rotating trowel plate 521 moves to a position close to the receiving frame 22, it tilts and pushes the mortar in the receiving frame 22 toward the joint position, thereby filling and smoothing the recessed joint position.

[0055] Specifically, when the inner receiving plate 431 rotates toward the collecting plate 2, the front pushing block 221 will push the coordination rod 514 forward, so that the coordination rod 514 and the vertical plate 512 move forward together, and at the same time drive the rotating trowel plate 521 to move forward. At this time, due to the meshing action of the toothed protrusion 523 and the rack 524, the extension sleeve 522 will rotate, and drive the rotating trowel plate 521 to rotate, thereby causing the rotating trowel plate 521 to rotate to an inclined state, and at this time the inner receiving plate 431 is in a vertical state, and the rotating trowel plate 521 is in an inclined state with the left end backward. When the inner receiving plate 431 returns to its original position due to the action of the connecting spring, the rotating trowel plate 521 will drive the mortar to the joint position, and because the front pushing block 221 is separated from the coordination rod 514, the rotating trowel plate 521 quickly returns to its initial vertical state, thereby smearing the driven mortar at the joint position and further smoothing it.

[0056] The working steps of the present invention are as follows: the first step is to open a positioning hole on the front side of the wall to be plastered, and then position and install the horizontal support plate 11 through the positioning hole, matching hole and positioning nail to ensure the overall stability of the device. Then the operator puts the mixed mortar into the trapezoidal basket 31. At this time, the rear support plate 312 on the rear side of the trapezoidal basket 31 will be pressed against the wall at the rear side. Then the vertical electric slider is controlled to drive the collecting plate 2, the containing frame 22 and the mortar storage mechanism 3 to move upward synchronously. The mortar in the trapezoidal basket 31 will be successively attached to the wall from the opening position on the rear side of the trapezoidal basket 31, and the mortar will be pressed and smoothed by the rear support plate 312, and then the mortar will be further smoothed through the bottom of the containing frame 22, so that the mortar is flat.

[0057] In the second step, before the horizontal electric slider is located at the far right and the mortar is applied, first rotate the stud 423 to move the two whole edge blocks 422 backward and press them against the wall. Then control the vertical electric slider to drive the collection plate 2, the receiving frame 22 and the mortar storage mechanism 3 to move upward synchronously. The whole edge blocks 422 will then trim the left and right edges of the applied mortar.

[0058] In the third step, when the vertical electric slider drives the collecting plate 2, the containing frame 22 and the mortar storage mechanism 3 to move upward synchronously, the inner retracting plate 431 will also move upward synchronously. When the transmission rod 433 moves upward until it contacts the semicircular protrusion 231, since the angle between the inner retracting plate 431 and the square plate 432 is greater than 60°, the semicircular protrusion 231 will push the transmission rod 433 toward the collecting plate 2, thereby causing the inner retracting plate 431 to rotate toward the collecting plate 2, and causing the mortar accumulated at the position of the inner retracting plate 431 to be pushed back into the trapezoidal basket 31 again.

[0059] In the fourth step, when the collecting plate 2, the containing frame 22 and the mortar storage mechanism 3 move upward to the top position, the coordinating triangle block 324 will be pushed by the unlocking block 212 and move backward, and drive the locking rod 322 to move backward, so that the locking rod 322 is separated from the blocked plate 325 and the blocking effect on the blocked plate 325 is released. The trapezoidal basket 31 will rotate downward due to its own gravity and the gravity of the remaining mortar inside it, and finally rotate to the bottom of the retaining frame 22. During this process, the pushing member 33 will push the remaining mortar in the trapezoidal basket 31 toward the wall, and further apply the mortar to the wall.

[0060] The fifth step is to wait until the first section of mortar is applied, first rotate the trapezoidal basket 31 to the initial tilted state, and control the rotation of the stud 423, and move the whole side block 422 on the right into the rear through groove 421, and then control the horizontal electric slider to drive the collection plate 2, the receiving frame 22 and the mortar storage mechanism 3 to move to the left, and then repeat the above-mentioned plastering operation. In the subsequent plastering operation, the joint smoothing mechanism 5 will smooth the joints between the two sections of mortar, thereby making the overall plastering effect of the wall better.

A person skilled in the art may make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention, which are still covered by the scope of protection of the present invention.
