Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present utility model, the meaning of "several" is two or more, unless otherwise clearly and specifically defined.

[0038] Please also read Figures 1 to 3 The mortar and putty spraying device provided by the utility model is now described. The mortar and putty spraying device comprises a base 1, a spraying assembly 2 and a lifting assembly 3; the spraying assembly 2 comprises a lifting support column 21 arranged on the base 1, and a mechanical arm 22 fixed on the lifting support column 21; one end of the mechanical arm 22 extends upward and points to the area to be sprayed; a spray gun 23 is provided at the extended end of the mechanical arm 22; the lifting assembly 3 is arranged on the top of the base 1 and is located on one side of the lifting support column 21; the active end of the lifting assembly 3 has the freedom to move up and down in the vertical direction, and is connected to the mechanical arm 22; wherein, the lifting assembly 3 is used to drive the spraying assembly 2 to move up and down, and the upper end of the lifting support column 21 moves up and down with the spraying assembly 2.

[0039] Specifically, the bottom of the base 1 is provided with moving wheels, which can drive the spray gun 23 to move, thereby improving the convenience of the device.

[0040] It should be noted that the robotic arm 22 is used to drive the spray gun 23 to move up and down through the swinging and lifting action of the robotic arm 22, and the movement of the robotic arm 22 is realized through the control component. The movement trajectory of the robotic arm 22 can be written and designed through the control program. The control principle of the control component and the specific structure of the robotic arm 22 belong to the prior art and will not be repeated here.

[0041] By setting the lifting component 3 on one side of the robotic arm 22 and fixing the robotic arm 22 on the lifting support column 21, when the lifting component 3 lifts the robotic arm 22 upward, the upper end of the lifting support column 21 is always supported on the bottom of the robotic arm 22, thereby ensuring the lifting and lowering stability of the robotic arm 22 and avoiding deviation of the robotic arm 22 during the lifting and lowering process, which affects the spraying operation.

[0042] Optionally, the lifting support column 21 uses a lifting hydraulic cylinder or a lifting cylinder, so that the lifting support column 21 is always supported at the bottom of the mechanical arm 22 to ensure the stability of the mechanical arm 22.

[0043] Compared with the prior art, the mortar and putty spraying device provided by the utility model is connected to the spray gun 23 through a mechanical arm 22, so that the spray gun 23 can be adjusted within a first height range through the swing of the mechanical arm 22, thereby expanding the spraying range of the spray gun 23; and the mechanical arm 22 and the spray gun 23 are driven to move up and down through the lifting component 3 to achieve the adjustment of the second height range of the spray gun 23, further expanding the spraying range of the spray gun 23, so as to solve the spraying problem in an area with a larger height range value, and at the same time avoid the problem of the overall volume of the mechanical arm 22 being too large. The mortar and putty spraying device provided in the present application can save floor space, is flexible in operation, can achieve two-level adjustment of the height of the spraying area, and is convenient for completing the spraying operation in a small operating space.

[0044] See also Figure 2 In some possible embodiments, the lifting assembly 3 includes a lifting platform 31, a chain transmission member 32 and a driving member 33; the lifting platform 31 is arranged on the top of the base 1 and is located on one side of the lifting support column 21; the chain transmission member 32 includes a transmission chain 321 extending in the vertical direction; the transmission chain 321 is fixedly connected to the lower end of the mechanical arm 22; the driving member 33 is fixed on the lifting platform 31; the power output end of the driving member 33 is connected to the power of the chain transmission member 32.

[0045] Specifically, the driving member 33 drives the robot arm 22 to move up and down through the chain transmission member 32. When the driving member 33 drives the transmission chain 321 of the chain transmission member 32 to move, the transmission chain 321 rises or falls in the vertical direction. At this time, the lower end of the robot arm 22 is pulled up or down, thereby driving the spray gun 23 to move up and down.

[0046] It should be understood that for a small range of height adjustment, the spray gun 23 can be adjusted up and down by swinging the robot arm 22, and for a large range of height adjustment, spraying within a lower height range can be achieved by first swinging the robot arm 22, and then the position of the spray gun 23 can be adjusted by the lifting action of the lifting component 3, thereby achieving spraying at a higher position.

[0047] As another embodiment of the above-mentioned lifting component 3, the lifting component 3 can also be a combination of a lifting platform 31, a belt transmission member and a second driving member 33. The second driving member 33 drives the robot arm 22 to rise and fall by driving the transmission member. Specifically, by replacing the above-mentioned connecting transmission member with a belt transmission member, the conveyor belt is connected to the lower end of the robot arm 22, thereby driving the robot arm 22 to move up and down when the conveyor belt is raised and lowered.

[0048] See also Figure 2 In some embodiments, the chain transmission member 32 also includes two transmission wheels 322 and multiple groups of connecting plates 323; the two transmission wheels 322 are arranged on the lifting platform 31 at an interval up and down; one of the transmission wheels 322 is connected to the power output end of the driving member 33; wherein the transmission chain 321 is wound around and meshed with the two transmission wheels 322; multiple groups of connecting plates 323 are arranged at an interval up and down; one end of each connecting plate 323 is fixedly connected to the transmission chain 321, and the other end of the connecting plate 323 extends horizontally and is fixed to the lower end of the mechanical arm 22 to form the active end of the lifting component 3.

[0049] The transmission wheels 322 are arranged at intervals up and down so that the transmission chain 321 can extend in the vertical direction, and then when the transmission chain 321 rotates up and down, the robot arm 22 is driven to rise and fall; by arranging multiple groups of connecting plates 323, the transmission chain 321 is connected to the robot arm 22, and the multiple groups of connecting plates 323 are arranged at intervals, so that the force on the lower end of the robot arm 22 can be dispersed, ensuring that when one group of connecting plates 323 breaks, the robot arm 22 will not fall and be damaged. At the same time, the multiple groups of connecting plates 323 can ensure the connection strength between the two.

[0050] See also Figure 2Exemplarily, the driving member 33 includes a driving motor 331, a driving gear 332 and a driven gear 333; the driving motor 331 is fixed on the lifting platform 31; a driving gear 332 is provided at the power output end of the driving motor 331; the driven gear 333 is coaxial with one of the transmission wheels 322 and is arranged at an interval; the driven gear 333 and the driving gear 332 are meshed with each other for transmission.

[0051] The driving motor 331 is used to drive the driving gear 332 to rotate, thereby causing the driving gear 332 to drive the driven gear 333 to rotate; since the driven gear 333 is coaxial with one set of transmission wheels 322 and is arranged at an interval, the driven gear 333 can drive one of the transmission wheels 322 to rotate through the transmission shaft connected to the two, thereby realizing the transmission of the transmission chain 321.

[0052] Optionally, a set of tensioning wheels is provided between the two transmission wheels 322 to tension the transmission chain 321 to prevent the transmission chain 321 from being loosened.

[0053] See also Figure 2 In some embodiments, the lifting platform 31 is a box-type structure, and the chain transmission member 32 and the driving member 33 are arranged inside the lifting platform 31; a clearance groove 311 is provided on the side of the lifting platform 31 facing the robotic arm 22, and the connecting plate 323 passes through the clearance groove 311 and is connected to the robotic arm 22.

[0054] By configuring the lifting platform 31 as a box structure, the chain transmission member 32 and the driving member 33 can be prevented from being exposed to the outside, thereby avoiding interference from dust or steam, and preventing the sprayed mortar or putty from affecting the lifting action of the lifting component 3 .

[0055] The clearance groove 311 is provided to prevent the connection plate 323 from interfering with the lifting platform 31 when the robot arm 22 is raised or lowered.

[0056] See also Figure 2 , illustratively, a limiting plate 34 is also provided on the top of the lifting platform 31 , and the limiting plate 34 extends horizontally toward one side of the robotic arm 22 .

[0057] The limiting plate 34 is provided to prevent the robot arm 22 from moving upwards beyond a preset height and causing derailment.

[0058] See also Figure 2 In some possible embodiments, a connecting component 4 is provided at the extending end of the robot arm 22 , and the connecting component 4 is connected to the spray gun 23 .

[0059] The connection assembly 4 is provided so as to fix the spray gun 23 to the extended end of the mechanical arm 22 , thereby ensuring the connection strength between the mechanical arm 22 and the spray gun 23 .

[0060] See also Figure 2 and Figure 3 In some embodiments, the connecting assembly 4 includes a connecting block 41 and a limiting bolt 42; one end of the connecting block 41 is connected to the extending end of the robotic arm 22, and the other end extends upward; a groove 411 is downwardly opened at the top of the connecting block 41; a spray gun 23 is penetrated in the groove 411; one end of the limiting bolt 42 sequentially passes through one side wall of the groove 411 and the spray gun 23, and is fixed in the other side wall of the groove 411.

[0061] A connecting block 41 is provided so that the lower end of the connecting block 41 can be screwed and fixed to the extended end of the robot arm 22, and the above-mentioned groove 411 is opened on the connecting block 41 so that the tail end of the spray gun 23 can be inserted into the groove 411, so that the spray end of the spray gun 23 is directed to the area to be sprayed; a limiting bolt 42 is provided to fix the connecting block 41 and the spray gun 23.

[0062] See also Figure 2 and Figure 3 Exemplarily, the connecting assembly 4 also includes two sets of adjustment plates 43, which are correspondingly attached to the two side walls of the groove 411 and clamped on both sides of the spray gun 23; wherein the limit bolt 42 is passed between the spray gun 23 and the two adjustment plates 43, and both ends pass through the two side walls of the groove 411 and are fixed on the connecting block 41.

[0063] By providing the adjustment plate 43 so that the adjustment plate 43 is clamped on both sides of the spray gun 23 , a machining gap is avoided between the side wall of the groove 411 and the spray gun 23 , thereby improving the connection stability between the spray gun 23 and the connecting block 41 .

[0064] Specifically, the thickness of each group of adjustment plates 43 can be selected according to actual needs. Preferably, a group of adjustment plates 43 can be formed by overlapping a plurality of connecting plates to adapt to the distance between the side wall of the groove 411 and the spray gun 23.
