Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, in particular to a working device. BACKGROUND

[0002] In the process of building construction, the wall surface needs to be plastered to improve the durability and aesthetics of the wall surface. In the process of wall surface spraying and plastering, the excess mortar inevitably falls off. If the function of recycling and reusing the excess mortar is integrated on the existing plastering robot, it may increase the outer size of the plastering robot, affecting the flexible mobility of the plastering robot.

[0003] Figure 8 A structural schematic diagram of an existing working device is shown, Figure 9 For Figure 8 A local enlarged view at B.

[0004] As Figure 8 And Figure 9 shown, an existing working device 200 includes a walking chassis 210, a spraying execution mechanism 220, a surplus material collecting mechanism 230, a slurry conveying mechanism 240, and a stand cabinet 250. The spraying execution mechanism 220 and the stand cabinet 250 are installed on the walking chassis 210, and the surplus material collecting mechanism 230 is slidably installed on the walking chassis 210 to switch between a material receiving position close to the spraying execution mechanism 220 and a stowed position accommodated in the walking chassis 210. The slurry conveying mechanism 240 includes a slurry inlet pipe 241, a surplus material pipe 242, a spraying pipe 243, and a merging piece 244. The slurry inlet pipe 241, the surplus material pipe 242, and the spraying pipe 243 are communicated through the merging piece 244. The spraying pipe 243 and the merging piece 244 are fixedly arranged relative to the stand cabinet 250, and the two ends of the surplus material pipe 242 are respectively communicated with the merging piece 244 and a surplus material discharge port of the surplus material collecting mechanism 230, and the surplus material discharge port and the merging piece 244 are arranged on the same side. During the movement of the surplus material collecting mechanism 230, one end of the surplus material pipe 242 is fixedly arranged, and the other end moves synchronously with the surplus material collecting mechanism 230. In order to adapt to the stroke range of the surplus material collecting mechanism 230, the surplus material pipe is arranged as a flexible pipe and is provided with a surplus pipe section. When the surplus material collecting mechanism 230 is located at the stowed position, the flexible pipe is bent into a U shape and partially exceeds the outline range of the walking chassis 210, causing the outer size of the working device 200 to increase. The working device 200 not only cannot pass through narrow spaces, but also is easy to scratch external obstacles, and its flexible mobility is seriously affected. SUMMARY

DETAILED DESCRIPTION

[0059] In order to make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the following will be combined with the accompanying drawings for the embodiments of the present application to make a clear and complete description of the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the accompanying drawings can be arranged and designed in various different configurations.

[0060] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work are within the scope of protection of the present application.

[0061] Figure 1 Shown is a structural schematic diagram of a working device of some embodiments of the present application; Figure 2 Shown is a partial structural schematic diagram of a working device of some embodiments of the present application (not shown is a spraying execution mechanism).

[0062] As Figure 1and Figure 2 As shown, some embodiments of the present application provide an operating device 100, comprising a spraying actuator 120, a residual material collection mechanism 130, a slurry conveying system 140, and a displacement mechanism 150. The spraying actuator 120 is used to spray slurry onto the working surface, and the residual material collection mechanism 130 is used to receive the residual material from the spraying actuator 120. The residual material collection mechanism 130 has a residual material outlet 1332, and the slurry conveying system 140 comprises a slurry inlet pipe 141, a residual material pipe 142, a spraying pipe 143, and a junction 144. The slurry inlet pipe 141 is used to communicate with an external slurry supply device to input slurry, the residual material pipe 142 is used to communicate with the residual material outlet 1332 to output residual material, and the spraying pipe 143 is used to convey slurry to the spraying actuator 120. The slurry inlet pipe 141, the residual material pipe 142, and the spraying pipe 143 are connected through the junction 144. The displacement mechanism 150 is used to drive the merging member 144 and the residual material collecting mechanism 130 to move synchronously, so that the residual material collecting mechanism 130 switches between the material receiving position and the retracted position.

[0063] In the working device 100 of the present embodiment, the merging member 144 and the residual material collection mechanism 130 are synchronously driven by the displacement mechanism 150. One end of the residual material tube 142 is connected to the residual material collection mechanism 130, and the other end is connected to the merging member 144. When the residual material collection mechanism 130 switches between the material receiving position and the stowed position, both ends of the residual material tube 142 move synchronously. This allows the residual material tube 142 to be configured as a straight tube, thereby maintaining the overall dimensions of the working device 100 and improving the mobility of the working device 100.

[0064] The specific structural form of the operating equipment 100 according to the embodiment of the present application is described in detail below.

[0065] like Figure 1 and Figure 2 As shown, the operating equipment 100 further includes a traveling chassis 110 , a cabinet 160 and a lifting mechanism 170 , and the cabinet 160 and the lifting mechanism 170 are installed on the traveling chassis 110 .

[0066] The walking chassis 110 can drive the operating equipment 100 to achieve automatic walking, so that the operating equipment 100 can move flexibly; the cabinet 160 is used to store electrical components, and the lifting mechanism 170 is used to drive the spraying actuator 120 to rise and fall for spraying and scraping operations.

[0067] The residual material collecting mechanism 130 is slidably mounted on the traveling chassis 110 in the forward and backward directions. The displacement mechanism 150 is used to drive the residual material collecting mechanism 130 to move forward and backward to have a material receiving position extending out of the traveling chassis 110 and a stowed position stored in the traveling chassis 110 .

[0068] For ease of description, the front-rear direction in the embodiments of the present application is the first horizontal direction X, the left-right direction is the second horizontal direction Y, and the up-down direction is the vertical direction Z.

[0069] In some embodiments of the present application, the vertical cabinet 160 and the lifting mechanism 170 are spaced apart along the second horizontal direction Y, and the vertical cabinet 160 is located on one side of the lifting mechanism 170.

[0070] As shown in Figure 1 and Figure 2 The working device 100 further comprises a first drag chain 180, both ends of the first drag chain 180 are a first end 181 and a second end 182, the first end 181 is installed on the rear side (i.e. one side along the first horizontal direction X) of the vertical cabinet 160 and is spaced apart from the converging piece 144 along the second horizontal direction Y, and the second end 182 extends forward to connect the spraying execution mechanism 120, wherein the spraying pipe 143 extends from the converging piece 144 into the first end 181 of the first drag chain 180 and extends forward along the extension track of the first drag chain 180 to connect the spraying execution mechanism 120, and the part of the spraying pipe 143 from the converging piece 144 to the first end 181 of the first drag chain 180 is defined as a first pipe segment 1431, and the first pipe segment 1431 is located within the edge of the walking chassis 110.

[0071] Through this kind of structure, the spraying pipe 143 passes through the first drag chain 180, and the arrangement position is limited by the first drag chain 180, which can reduce the degree of freedom of the spraying pipe 143 on the basis of ensuring that the spraying pipe 143 allows the converging piece 144 and the spraying execution mechanism 120 to move, avoids the spraying pipe 143 from exceeding the edge of the walking chassis 110, and reduces the moving flexibility of the working device 100. The first pipe segment 1431 is arranged within the edge of the walking chassis 110, and the arrangement of the first pipe segment 1431 will not affect the moving flexibility of the working device 100.

[0072] In other embodiments, the first drag chain 180 can also not be provided, and the excess material collecting mechanism 130 and the vertical cabinet 160 are spaced apart along the second horizontal direction Y, and the spraying pipe 143 is at least partially arranged between the excess material collecting mechanism 130 and the vertical cabinet 160.

[0073] Through the structural form, one end of the spraying pipe 143 is connected with the converging piece 144, the other end is connected with the spraying execution mechanism 120, the spraying pipe 143 passes through between the excess material collecting mechanism 130 and the vertical cabinet 160, and is bent and accommodated by using the space between the excess material collecting mechanism 130 and the vertical cabinet 160, the excess bending part of the spraying pipe 143 does not exceed the outer size of the traveling chassis 110, so that the structure of the working device 100 is kept compact. Alternatively, the excess material collecting mechanism 130 and the vertical cabinet 160 can also be freely arranged on the traveling chassis 110, and the accommodation position of the spraying pipe 143 is limited by other ways. For example, a guide groove is arranged on the traveling chassis 110, and the spraying pipe 143 is accommodated in the guide groove.

[0074] The excess material collecting mechanism 130 is used for collecting the excess material in the spraying execution mechanism 120 and inputting the excess material to the slurry conveying system. The following illustrates a specific structural form of the excess material collecting mechanism 130.

[0075] Figure 3 and Figure 4 The structural schematic diagrams of two views of the excess material collecting mechanism in the working device of some embodiments of the application are shown.

[0076] As shown in Figure 2 , Figure 3 and Figure 4 , specifically, the excess material collecting mechanism 130 includes a moving frame 131, a material bin 132 and a slurry pump 133. The moving frame 131 is slidably arranged on the traveling chassis 110 along the first horizontal direction X through a guide rail assembly 134 (as shown in Figure 1 ), the displacement mechanism 150 is arranged on the traveling chassis 110 and is used for driving the moving frame 131 to move along the first horizontal direction X, and the slurry pump is fixedly arranged on the moving frame 131. The bottom of the material bin 132 is provided with a discharge port 1322, the slurry pump 133 is arranged at the bottom of the material bin 132, the inlet 1331 of the slurry pump 133 is communicated with the discharge port 1322 of the material bin 132, and the outlet of the slurry pump 133 is a excess material discharge port 1332, which is communicated with the converging piece 144 through the excess material pipe 142.

[0077] Through the structural form, the excess material enters the slurry pump 133 from the discharge port 1322 at the bottom of the material bin 132, and the slurry pump 133 pumps the excess material to the excess material pipe 142 to enter the converging piece 144 through the excess material pipe 142.

[0078] In some embodiments of the application, the material bin 132 is also provided with a vibrating motor 135, which is used for avoiding that the excess material in the material bin 132 is solidified and adhered to the inner wall of the material bin 132. Among them, the vibrating motor 135 is provided with two, one of which is arranged at the inlet 1321, and the other is arranged at the outer wall 1323 of the material bin 132.

[0079] Please refer to Figure 4 In some embodiments of the present application, the excess material outlet 1332 and the excess material pipe 142 are communicated through a connecting portion 137 (please refer to Figure 2 The excess material outlet 1332 of the slurry pump 133 is provided with a material guiding portion 136, which is located below the connecting portion 137 and used to receive the leaked material of the connecting portion 137.

[0080] Through the above structure, the material guiding portion 136 can receive the leaked material of the connecting portion 137, so as to avoid the leaked material from falling on the traveling chassis 110.

[0081] Specifically, the connecting portion 137 can be a joint with two interfaces, one of which is communicated with the excess material outlet 1332, and the other of which is communicated with the excess material pipe 142.

[0082] In other embodiments, the connecting portion 137 can also refer to the threaded or clamped portion of the excess material outlet 1332 and the excess material pipe 142.

[0083] Please refer to Figure 4 In some embodiments of the present application, the material guiding portion 136 has a slope surface 1361, which extends downward from top to bottom along a direction away from the excess material outlet 1332, and is located below the connecting portion 137 and used to receive and guide the leaked material of the connecting portion 137.

[0084] Through the above structure, the slope surface 1361 receives the leaked material and can timely discharge the leaked material.

[0085] Further, the excess material collecting mechanism 130 is installed on the traveling chassis 110 and switches between the material receiving position and the stowed position relative to the traveling chassis 110, and when the excess material collecting mechanism 130 is located at the stowed position, the extension end of the slope surface 1361 exceeds the edge of the traveling chassis 110.

[0086] Specifically, the extension end of the slope surface 1361 away from the excess material outlet 1332 is a first edge 1362, and when the excess material collecting mechanism 130 is located at the stowed position, the projection of the first edge 1362 on the horizontal plane is located outside the projection contour of the traveling chassis 110.

[0087] Through the above structure, the leaked material is discharged from the first edge 1362 of the slope surface 1361, and the first edge 1362 exceeds the edge of the traveling chassis 110, so as to discharge the leaked material to the area outside the traveling chassis 110, thereby avoiding the leaked material from falling on the traveling chassis 110 even after being guided by the slope surface 1361.

[0088] In other embodiments, a material receiving groove can also be arranged below the connecting portion 137 to receive the leaked material.

[0089] As shown in the drawings, in some embodiments of the present application, the merging member 144 is fixedly arranged on the excess material collecting mechanism 130. Figure 2

[0090] Through this kind of structural form, the merging member 144 and the excess material collecting mechanism 130 can be synchronously moved, and the assembly is convenient and simple.

[0091] Specifically, the merging member 144 can be directly fixedly arranged on the excess material collecting mechanism 130, for example, by welding, clamp connection, etc.; the merging member 144 can also be indirectly fixedly arranged on the excess material collecting mechanism 130 through other components, for example, the spraying pipe 143 or the excess material pipe 142 can be directly fixed on the excess material collecting mechanism 130, or a detection element communicating with the slurry conveying system 140 can be arranged, and the merging member 144 is indirectly fixed by fixing the detection element.

[0092] As shown in the drawings, in some embodiments of the present application, the merging member 144 is fixedly arranged on the outer wall 1323 of the bin 132. Figure 2

[0093] Through this kind of structural form, the merging member 144 can be installed by using the area of the outer wall 1323 of the bin 132, and has sufficient installation space, which reduces the assembly difficulty.

[0094] In other embodiments, the merging member 144 can also be arranged on other parts of the excess material collecting mechanism 130. For example, the merging member 144 can also be arranged on the moving frame 131 or the slurry outlet pump 133, or other connecting members are arranged to fixedly connect the merging member 144 and the excess material collecting mechanism 130.

[0095] Optionally, the excess material collecting mechanism 130 further comprises a laser detector 138 and a slurry outlet pump driving assembly 139. The laser detector 138 is arranged on the bin 132, and is used to detect the height of the excess material in the bin 132. When the height of the excess material in the bin 132 exceeds the maximum limit, the slurry outlet pump 133 can be started to promote the excess material in the bin 132 to be discharged to the spraying pipe 143, so as to avoid the excess material overflowing into the inlet 1321. The bottom of the shell of the slurry outlet pump 133 is provided with a drain 1333, when it is necessary to clean the bin 132, the cleaning liquid is injected from the inlet 1321, and after the inner wall of the bin 132 is cleaned, the drain 1333 is opened to discharge the sewage.

[0096] ​​Optionally, the excess material collecting mechanism 130 further comprises a slurry outlet pump driving assembly 139 for driving the screw of the slurry outlet pump 133 to rotate to drive the excess material to be discharged along the first horizontal direction X. The slurry outlet pump driving assembly 139 comprises a second motor 1391 and a chain 1392, the second motor 1391 is fixedly arranged on the moving frame 131, the screw of the slurry outlet pump 133 and the output end of the second motor 1391 are respectively provided with gears, and the two gears are drivingly connected through the chain 1392 to transmit the power of the second motor 1391 to the screw.

[0098] As shown in Figs. 1 and 2, in some embodiments of the present application, the slurry conveying system 140 further comprises a flow meter 145, the spray pipe 143 and the merging piece 144 are communicated through the flow meter 145, and the flow meter 145 is fixedly arranged on the excess material collecting mechanism 130.

[0099] In some embodiments of the present application, the merging piece 144 has a first passage 1441 extending vertically downward, a second passage 1442 extending vertically upward, and a third passage 1443 extending backward and obliquely downward, the first passage 1441, the second passage 1442 and the third passage 1443 are communicated with each other, the first passage 1441 is communicated downward with the excess material pipe 142, the second passage 1442 is communicated upward with the spray pipe 143, and the third passage 1443 is communicated backward into the slurry inlet pipe 141.

[0100] Through the structural form, the merging piece 144 is communicated with the excess material pipe 142, the spray pipe 143 and the slurry inlet pipe 141 through the three passages respectively, so that the excess material in the excess material pipe 142 and the slurry in the slurry inlet pipe 141 enter the spray pipe 143 together, pass through the spray pipe 143 into the spraying executing mechanism 120, and provide the spraying executing mechanism 120 with slurry. The spray pipe 143 extends upward, which can avoid the existence of bubbles in the slurry in the spray pipe 143; the third passage 1443 is communicated backward into the slurry inlet pipe 141, which is easy to be communicated with the external slurry supply device.

[0101] Through the structural form, the merging piece 144 is communicated with the excess material pipe 142, the spray pipe 143 and the slurry inlet pipe 141 through the three passages respectively, so that the excess material in the excess material pipe 142 and the slurry in the slurry inlet pipe 141 enter the spray pipe 143 together, pass through the spray pipe 143 into the spraying executing mechanism 120, and provide the spraying executing mechanism 120 with slurry. The spray pipe 143 extends upward, which can avoid the existence of bubbles in the slurry in the spray pipe 143; the third passage 1443 is communicated backward into the slurry inlet pipe 141, which is easy to be communicated with the external slurry supply device.

[0102] ​The two ends of the flow meter 145 are communicated with the third channel 1443 and the spraying pipe 143 respectively, and the flow meter 145 is fixedly arranged on the outer wall 1323 of the material bin 132 of the excess material collecting mechanism 130, so as to indirectly fix the merging piece 144 on the outer wall 1323 of the material bin 132.

[0103] In some embodiments of the present application, the slurry conveying system 140 further comprises a bracket 146, which is fixedly arranged on the excess material collecting mechanism 130, and the flow meter 145 is mounted on the bracket 146.

[0104] Through the above structure, the flow meter 145 can be firmly and reliably fixed on the excess material collecting mechanism 130, and the assembly is simple and easy to implement.

[0105] Specifically, the bracket 146 and the merging piece 144 are arranged on the same side of the excess material collecting mechanism 130, and the bracket 146 is connected with the moving frame 131, the slurry pump 133 and the material bin 132 to serve as a reinforcing rib. The flow meter 145 is attached to the outer wall 1323 of the material bin 132 and is fixed on the bracket 146 by a clamp.

[0106] Further, based on the above-mentioned embodiment that the material bin 132 is provided with the laser detector 138, the laser detector 138 is fixedly arranged on the bracket 146, one end of the bracket 146 is fixedly arranged on the outer wall 1323 of the material bin 132, and the other end extends to the material inlet 1321 of the material bin 132, so that the laser detector 138 can detect the height of the excess material in the material bin 132. The laser detector 138 is adjustably mounted on the bracket 146, so that the position of the laser detector 138 can be easily adjusted to make the laser emission direction of the laser detector 138 consistent with the vertical direction Z.

[0107] In some embodiments of the present application, the excess material pipe 142 is a hard pipe, which increases the strength of the excess material pipe 142 and fixes the position of the excess material pipe 142.

[0108] For example, the material of the excess material pipe 142 can be PVC or other composite pipes.

[0109] In other embodiments, the excess material pipe 142 can also be a flexible pipe to facilitate flexible assembly.

[0110] In some embodiments of the present application, the excess material pipe 142 is a straight pipe to reduce the length of the excess material pipe 142.

[0111] For example, the merging piece 144 and the excess material outlet 1332 are spaced apart in the vertical direction Z, and the excess material pipe 142 extends in the vertical direction Z, and the projection of the excess material pipe 142 falls within the contour of the traveling chassis 110 in the XY plane, without increasing the outer size of the working device 100; for another example, the merging piece 144 and the excess material outlet 1332 are staggered in the vertical direction Z, and the two ends of the excess material pipe 142 are connected with the merging piece 144 and the excess material outlet 1332 respectively.

[0112] In other embodiments, the excess material pipe 142 can also have appropriate bending to reasonably utilize the installation space without increasing the outer size of the working device 100.

[0113] In some embodiments of the present application, the spraying pipe 143 is a hose.

[0114] Through this kind of structure, one end of the spraying pipe 143 is in communication with the merging piece 144, and the other end is in communication with the spraying execution mechanism 120, which can adapt to the stroke range of the spraying execution mechanism 120 and the stroke range of the merging piece 144 following the excess material collecting mechanism 130.

[0115] As shown in Figure 1 and Figure 2 In some embodiments of the present application, along the first horizontal direction, the merging piece 144 and the spraying execution mechanism 120 are respectively arranged on opposite sides of the excess material collecting mechanism 130.

[0116] Specifically, the length direction of the outer size of the excess material collecting mechanism 130 extends along the first horizontal direction X, and the width direction extends along the second horizontal direction Y, and the merging piece 144 and the spraying execution mechanism 120 are respectively arranged on both sides of the hopper 132 along the first horizontal direction X.

[0117] Through this kind of structure, the spraying execution mechanism 120 can be arranged on one side of the excess material collecting mechanism 130, and there is enough space for spraying operation, and the merging piece 144 can be arranged on the other side of the excess material collecting mechanism 130, and there is enough space for arranging the slurry conveying system 140, and the merging piece 144 and the spraying execution mechanism 120 are spaced apart along the moving direction of the excess material collecting mechanism 130, which can not only meet the moving stroke of the merging piece 144, but also shorten the length of the spraying pipe 143.

[0118] In other embodiments, the spraying execution mechanism 120 and the merging piece 144 can also be flexibly arranged according to the installation space.

[0119] As shown in Figure 1 and Figure 2As shown, in some embodiments of the present application, the merging member 144 and the excess material outlet 1332 are arranged on the same side of the excess material collecting mechanism 130, which can reduce the distance between the merging member 144 and the excess material outlet 1332, thereby shortening the length of the excess material pipe 142.

[0120] In other embodiments, the positions of the merging member 144 and the excess material outlet 1332 can not be limited, and since the merging member 144 moves synchronously with the excess material collecting mechanism 130, the area occupied by the excess material pipe 142 can be reduced by appropriately bending the excess material pipe 142, thereby keeping the overall structure of the working device 100 compact.

[0121] The spraying execution mechanism 120 is used to spray the slurry to the working surface, and is docked with the excess material collecting mechanism 130 to pour the excess material collected during the spraying operation into the hopper 132. The following illustrates a structure of the spraying execution mechanism 120.

[0122] Figure 6 For Figure 1 A local enlarged view at A.

[0123] As Figure 1 and Figure 6 shown, the spraying execution mechanism 120 includes a mounting frame 121, a squeegee assembly 122, a spraying assembly 123, and a slurry discharge assembly (not shown), the squeegee assembly 122 and the spraying assembly 123 are both mounted on the mounting frame 121, and an overflow tank (not shown) is arranged inside the mounting frame 121, one end of the overflow tank in the length direction is provided with a discharge port (not shown), and the slurry discharge assembly is used to drive the excess material collected in the overflow tank to be discharged from the discharge port, for example, the slurry discharge assembly includes a slurry discharge squeegee, and can also include a screw rod. The squeegee assembly 122 includes a trowel, which is used to squeegee the wall surface, and the spraying assembly 123 includes a spray head, which is used to spray the slurry to the wall surface. The spraying pipe 143 is in communication with the slurry inlet of the spraying assembly 123. In other embodiments, the slurry discharge assembly can not be provided, and the excess material collected in the overflow tank is discharged from the discharge port by gravity.

[0124] The spraying execution mechanism 120 is adjustably mounted on the traveling chassis 110, so as to be able to perform normal spraying operation, discharge excess material to the excess material collecting mechanism 130, and retract to improve the mobility of the working device 100.

[0125] As Figure 1 and Figure 2As shown, in some embodiments of the present application, the working device 100 further comprises a rotating mechanism (not shown in the figure), which is installed at the execution end of the lifting mechanism 170, and the execution end of the rotating mechanism is connected with the spraying execution mechanism 120. The rotating mechanism is used to further drive the spraying execution mechanism 120 to rotate at the output end of the lifting mechanism 170, so as to switch the spraying execution mechanism 120 between the working position and the retracted position.

[0126] Among them, the spraying execution mechanism 120 is narrow and long as a whole, when the spraying execution mechanism 120 is located at the working position, the length direction of the spraying execution mechanism 120 extends along the horizontal direction, and the spraying execution mechanism 120 is used for spraying work and slurry discharge work; when the spraying execution mechanism 120 is located at the retracted position, the length direction of the spraying execution mechanism 120 extends along the vertical direction Z, and the walking chassis 110 drives the working device 100 to move as a whole.

[0127] In other embodiments, the spraying execution mechanism 120 can also be separately provided with a slurry discharge position, so that the discharge port of the spraying execution mechanism 120 is correspondingly arranged with the feeding port 1321 of the material bin 132. When the spraying execution mechanism 120 is used for discharging slurry, the length direction of the spraying execution mechanism 120 can extend along the horizontal direction, or the discharge port can be located at a low position, so as to facilitate the discharge of the remaining material by gravity.

[0128] As shown in Figure 1 and Figure 2 In some embodiments of the present application, along the first horizontal direction X, the front side of the lifting mechanism 170 is connected with the spraying execution mechanism 120 to realize lifting work, the remaining material collecting mechanism 130 is installed on the walking chassis 110, the remaining material collecting mechanism 130 is spaced apart from the lifting mechanism 170 along the second horizontal direction Y, and the remaining material collecting mechanism 130 is located on the side of the lifting mechanism 170 away from the cabinet 160. The converging piece 144 is fixed to the rear of the remaining material collecting mechanism 130 and does not overlap with the projection of the lifting mechanism 170 along the first horizontal direction X.

[0129] Through this kind of structure, the lifting mechanism 170, the spraying execution mechanism 120, the remaining material collecting mechanism 130 and the converging piece 144 can be reasonably arranged on the walking chassis 110, so that the working device 100 is compact in structure; and the projection of the converging piece 144 and the lifting mechanism 170 in the front-rear direction does not overlap, so that the converging piece 144 does not interfere with the lifting mechanism 170 during the synchronous movement of the remaining material collecting mechanism 130.

[0130] Figure 7 As shown is a structural schematic diagram of a displacement mechanism in the working device of some embodiments of the present application.

[0131] As shown in Figure 2 and Figure 7As shown, in some embodiments of the present application, the displacement mechanism 150 is a common motor screw rod nut mechanism, the motor is arranged on the walking chassis 110, the screw rod is rotatably arranged on the walking chassis 110 along the first horizontal direction X, the nut is fixedly arranged with the moving frame 131, and the motor drives the screw rod to rotate, so as to drive the moving frame 131 to displace along the first horizontal direction X through the nut.

[0132] As shown in Figure 2 and Figure 7 Specifically, the displacement mechanism 150 includes a first motor 151, a screw rod 152, a nut 153 and a mounting plate 154, the mounting plate 154 is fixedly mounted on the walking chassis 110, the first motor 151 is mounted on the mounting plate 154, the screw rod 152 is rotatably mounted on the mounting plate 154 along the first horizontal direction X, the screw rod 152 is threadedly matched with the nut 153, and the nut 153 is fixedly arranged with the moving frame 131. The first motor 151 can drive the screw rod 152 to rotate, and in turn drive the moving frame 131 to move relative to the mounting plate 154 along the first horizontal direction X through the nut 153.

[0133] Further, the displacement mechanism 150 further includes an organ case 155 arranged on the mounting plate 154, the organ case 155 covers the transmission connection part of the screw rod 152 and the first motor 151, and protects the transmission connection part of the first motor 151 and the screw rod 152.

[0134] In other embodiments, the displacement mechanism 150 can also be a gas cylinder, an electric push rod or the like linear driving member.

[0135] The working process of the working device 100 of the embodiment of the present application is as follows:

[0136] The walking chassis 110 moves according to the preset route to drive the working device 100 to reach the working site, and the lifting mechanism 170 is unfolded to form a top-to-bottom state, that is, the upper end of the lifting mechanism 170 abuts against the ceiling upward, and the lower end of the lifting mechanism 170 is fixed to the walking chassis 110 or abuts against the ground downward, so as to form a state that both upper and lower ends are fixed, which is called a top-to-bottom state;

[0137] The spraying execution mechanism 120 is adjusted to a horizontal state (working position), the spraying execution mechanism 120 is lowered along the guide rail of the lifting mechanism 170 to a height corresponding to the root of the wall surface, the lifting mechanism 170 drives the spraying execution mechanism 120 to perform spraying and troweling work from bottom to top along the vertical direction Z, the spraying execution mechanism 120 includes a spray head and a troweling plate, wherein the spray head sprays the slurry toward the wall surface, and the troweling plate forms a troweling angle with the wall surface to trowel the slurry on the wall surface from bottom to top;

[0138] During the process of troweling the slurry on the wall, the trowel moves upward, which causes the slurry on the wall to flow upward, and the slurry flows out of the trowel and flows backward along the upper end of the trowel to the overflow groove (not shown) ;

[0139] When the trowel completes a troweling operation from bottom to top, the spraying execution mechanism 120 is rotated from the horizontal state to the downward inclined state (the slurry discharge position), and the discharge port of the overflow groove is located at the lower end. The scraper in the overflow groove pushes the slurry out of the discharge port. The displacement mechanism 150 drives the surplus slurry collecting mechanism 130 to extend to the receiving position along the first horizontal direction X, so that the discharge port of the spraying execution mechanism 120 corresponds to the inlet 1321 of the material bin 132. The surplus slurry collected in the spraying execution mechanism 120 is discharged from the discharge port and enters the material bin 132.

[0140] When the laser detector 138 arranged on the material bin 132 detects that the height of the slurry in the material bin 132 reaches a preset value, the feedback is sent to the control system. The control system controls the slurry pump 133 to pump the surplus slurry out of the surplus slurry collecting mechanism 130. The surplus slurry enters the spraying pipe 143 through the converging piece 144, and the surplus slurry is recycled and reused.

[0141] When the scraping of the spraying execution mechanism 120 is completed, the displacement mechanism 150 drives the surplus slurry collecting mechanism 130 to switch to the retracted position, and the rotating mechanism drives the spraying execution mechanism 120 to switch to the horizontal state to prepare for the next spraying troweling operation at the work point.

[0142] The cleaning and maintenance process of the work equipment 100 of the embodiment includes cleaning of the surplus slurry collecting mechanism 130. The cleaning liquid enters the material bin 132 from the inlet 1321 of the material bin 132, enters the slurry pump 133 through the outlet 1322 of the material bin 132 for cleaning, and flows out of the material bin from the drain 1333 of the slurry pump 133, thereby completing the entire cleaning operation.

[0143] In the working process of the working device 100, the merging piece 144 is fixedly arranged on the outer wall 1323 of the hopper 132 through the flowmeter 145. On one hand, one end of the excess material pipe 142 is connected with the excess material outlet 1332 of the excess material collecting mechanism 130, and the other end is connected with the merging piece 144. The excess material pipe 142 as a whole moves synchronously with the excess material collecting mechanism 130, and can be arranged as a hard straight pipe, without increasing the outer size of the working device 100. On the other hand, one end of the spraying pipe 143 is connected with the merging piece 144, and the other end is connected with the inlet of the spraying execution mechanism 120. The merging piece 144 and the spraying execution mechanism 120 are arranged on the opposite sides of the excess material collecting mechanism 130 respectively. The spraying pipe 143 passes through the first drag chain 180 to limit the position of the spraying pipe 143. The spraying pipe 143 can be arranged as a flexible pipe, without increasing the outer size of the working device 100. Through the above structural improvement, the working device 100 has compact structure and good moving flexibility.

[0144] It should be noted that the features in the embodiments of the present application can be combined with each other without conflict.

[0145] The above only describes the preferred embodiments of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. within the spirit and principle of the present application shall be included in the protection scope of the present application.
