Description

Technical Field

[0001] This application relates to the field of architectural spraying machine technology, specifically to a putty mixing and grinding integrated mobile vehicle suitable for spraying robots. Background Technology

[0002] In the construction industry, the putty used in spray painting machines is typically prepared by a person who puts bagged material into a bucket, adds an appropriate amount of water, and then mixes it with a hand-held electric hammer. Finally, the mixed putty is manually poured into a grinder, and only after grinding is it poured into the spray painting robot's cylinder. Another method uses specialized equipment to mix and grind the putty (which is the model used in this example). This method mainly involves a dedicated drive chassis housing the mixing, pumping, and grinding equipment. (There are currently no similar solutions in the construction robot industry.)

[0003] Compared to mortar mixing methods in the construction industry, mortar has better fluidity than putty and does not require grinding. Putty is usually in powder form, so it is often impossible to mix it evenly using a mortar mixer. Because putty mixed with water has poor fluidity and flows slowly in pipes due to gravity, it is usually manually removed, poured into a grinder for grinding, and finally manually poured into a robot's hopper. Throughout the process, humans are involved in handling the material at every step. Unlike traditional putty application, manual mixing does not require high uniformity or particle size, while robots require very small or even no particles when spraying putty. Therefore, manual mixing inevitably introduces some particles. Additionally, putty or latex paint hardens with prolonged exposure to air. The higher efficiency of robots also increases the demand for putty. Therefore, a machine integrating putty mixing, grinding, and pumping is needed to meet the requirements of robots.

The hole at the rear end of the pump mounting bracket 102 is connected to the threaded hole at the top of the second receiving cavity 1012 of the chassis frame 101 using bolts. The threaded hole on one side of the chassis frame 101 is connected to the countersunk hole of the first hinge 108 using countersunk bolts, and another part of the first hinge 108 is connected to the shelf 109 using countersunk bolts. The pump mounting bracket 102 consists of three identical fan-shaped metal blocks connected in pairs through holes on their sides using bolts to form a circle, which is then bolted to the pump mounting bracket 102 through holes on its end face.

[0058] A steering control handle 105 is located on one side of the first receiving cavity 1011 and connected to the chassis frame 101. In use, it controls the direction of the mobile vehicle.

[0059] In some specific embodiments, the mixer 200 includes: a material cylinder 201, disposed within a first receiving cavity 1011 and fixedly connected to the bottom of the first receiving cavity 1011; a fixed base 202, disposed above the material cylinder 201; a stirring motor 203, one end of which is fixed to the fixed base 202 and the other end of which extends into the material cylinder 201; a stirring shaft 204, mounted on the other end of the stirring motor 203, for stirring the material in the material cylinder 201 under the drive of the stirring motor 203; and a fixing block 205, disposed on the fixed base 202, for fixing a liquid pump 300.

[0060] Specifically, the fixed base 202 includes multiple extension shafts 2021, one end of which protrudes from the outer peripheral wall of the material cylinder 201; the extension shafts 2021 have a Y-shaped structure; and the fixing block 205 is located at the center of the fixed base 202.

[0061] By setting the fixing block 205 at the center of the fixing base 202, the liquid pump 300 can operate without affecting the operation of the mixer 200, and can simultaneously extract the material inside the mixer 200 and transport it to the grinder 400 to achieve simultaneous mixing and grinding.

[0062] The mixer 200 also includes: multiple handles 206, each disposed at one end of each extension shaft 2021; a fixed base 207, installed between the fixed base 205 and the mixing motor 203, located between the handles 206 and the fixed block 205; and multiple V-shaped cover plates 208, each disposed between two adjacent extension shafts 2021, for opening or closing the material cylinder 201.

[0063] A fixed base 207 is installed between a fixed base 205 and a stirring motor 203, wherein the fixed base 207 is rotatable relative to the liquid pump 300. A V-shaped cover plate 208 is provided and connected to the fixed base 205 to form a cover plate for the material cylinder 201. During operation, the V-shaped cover plate 208 is closed to prevent material from splashing out of the material cylinder 208 during stirring, thus avoiding material waste and environmental pollution.

[0064] The handle 206 is connected to a threaded hole on a plurality of extended shafts 2021 placed on a fixed base 202 by means of its end thread.

[0065] Specifically, in the mixer 200, the material cylinder 201 is connected to the bottom plate of the first receiving cavity 1011 of the chassis frame 101 via a through hole in the elongated hole of the circular base at its bottom using bolts and nuts. The fixed base 202 is located above the material cylinder 201 and is fixed to the material cylinder 201 via a hinge mounting plate 209 and a V-shaped cover plate 208. The cylindrical output portion of one end of the stirring motor 203 passes through the center of the fixed base 207 and through a threaded hole located in the fixed base 207, and the stirring motor 203 is held in place and fixed using bolts. The stirring shaft 204 is connected to the stirring motor 203, and the stirring shaft 204 is bolted to the threaded end of the output shaft of the stirring motor 203 via a threaded hole at its end.

[0066] In some specific embodiments, a hinge mounting plate 209 is provided between the V-shaped cover plate 208 and the fixed base 202. One side of the hinge mounting plate 209 is fixed to the fixed base 202, and the other side is connected to the V-shaped cover plate 208. A second hinge 210 is provided on the hinge mounting plate 209 and is connected to the V-shaped cover plate 208.

[0067] Specifically, the hinge mounting plate 209 is bolted to the countersunk hole located above the fixing base plate 202 via a threaded hole on its upper part. The two holes of one side of the second hinge 210 are bolted to the threaded hole on the hinge mounting plate 209, and the hole of the other side of the second hinge 210 is bolted to the threaded hole of the V-shaped cover plate 208.

[0068] The V-shaped cover plate 208 is also provided with a hook seat 217. After the V-shaped cover plate 208 is opened, the V-shaped cover plate 208 is suspended on the hook 107 through the hook seat 217.

[0069] In some specific embodiments, the mixer 200 further includes a first bearing 211, a first shaft 212, a second bearing 213, a second shaft 214, a third bearing 215, and a bearing mounting base 216. The first bearing 211 and the first shaft 212 are installed at one end of the fixed base 202, located on one side of the handle 203; the end of the fixed base 202 is provided with a recess 2022, and the first shaft 212 is fixed in the recess 2022; the recess 2022 is provided with a waist hole 2023 through the fixed base 202 in the vertical direction, and the first shaft 212 passes through the first bearing 211, the first bearing 211 is located in the waist hole 2023, and can rotate relative to the upper surface of the material cylinder 201; there are multiple bearing fixing seats 216, which are installed on the lower surface of the end of the extension shaft 2021 of the fixed base 202; one end of the second shaft 214 is fixed on the bearing fixing seat 216, and the other end passes through the second bearing 213, the second bearing 213 is set close to the outer peripheral wall of the material cylinder 201; the third bearing 215 is fixed on the lower surface of the fixed base 202, located between adjacent bearing fixing seats 216.

[0070] The first shaft 212 is bolted to the countersunk holes at both ends of the first shaft and to the oblong groove 2022 above the fixed base plate 202. Simultaneously, the first shaft 212 passes through the center of the first bearing 211 and through the oblong hole 2023 on the fixed base plate 202. The steps formed at both ends of the fixed base plate 202 restrict the axial movement of the first bearing 211. Bolts are used to pass through the axis of the third bearing 215 and lock it below the fixed base plate 202. Two threaded holes on the end face of the bearing holder 213 are bolted to two holes on the edge of the fixed base plate 202. The second shaft 214 passes through the axis of the second bearing 213 and is inserted into the round hole on the side of the bearing holder 216. The step above the second shaft 214 restricts the axial movement of the second bearing 213. Another step on the second shaft 214 allows it to be bolted to the bearing holder 216.

[0071] In the above embodiment, the stirring motor 200 rotates, driving the connected stirring shaft 204 to stir the putty. By using the first bearing 211, third bearing 215, and second bearing 213 on the fixed base plate 202 to limit the flange surface at the upper end of the material cylinder 201, the fixed base plate 202 and the material cylinder 201 can rotate coaxially. By pulling the handle 206 to rotate the fixed base plate 202 and other components fixed thereon, a larger stirring area can be achieved to ensure uniform material mixing. While the fixed base plate 202 and other components fixed thereon are rotating, the liquid pump 300 can continue to operate; the two devices do not interfere with each other, improving efficiency.

[0072] In this application, the pump 300 passes through the pump locking block 103, the pump mounting bracket 102, the fixing block 205, the fixing base 202, and the hinge mounting plate 209 until the bottom suction port of the pump 300 contacts the bottom of the barrel 201. The fixing block 205 holds and fixes the pump 300, which passes through its central hole, by locking screws located on its side.

[0073] In some specific embodiments, the grinder 400 includes a hopper 401, a grinding device 402, a fixing plate 403, a discharge pipe 404, and a three-way valve 405. The hopper 401 is connected to the grinding device 402, the fixing plate 403 is disposed on the grinding device 402, the discharge pipe 404 is connected to the discharge port of the grinding device 402, and the three-way valve 405 is connected to the discharge pipe 404; the fixing plate 403 is fixed on the chassis frame 101 and located above the second receiving cavity 1012, and the grinding device 402 is located inside the second receiving cavity 1012.

[0074] The three-way valve 405 is equipped with a switching handle 4051 for selecting the discharge port.

[0075] The grinder 400 is fixed to the chassis frame 101 by connecting the threaded hole on it to the hole on the fixing plate 403. The discharge pipe 404 has threads at both ends, one end of which is connected to the threaded hole on the side of the grinder 400 and the other end is connected to the threaded hole of the three-way valve 405. By connecting the hopper 401 to the grinding device 402, the fixing plate 403 is set on the grinding device 402, the discharge pipe 404 is connected to the discharge port of the grinding device 402, and the three-way valve 405 is connected to the discharge pipe 404, the ground material is output from the three-way valve 405, and the material is discharged at a fixed point by changing the handle 4051.

[0076] Specifically, the pump 300 can directly extract the mixed material from the barrel 201 and transport it to the barrel 401 of the grinder 400. Simultaneously, the three-way valve 405 inside the grinder 400 allows for the control of whether the material is discharged or continues to be mixed (i.e., secondary mixing). The quick-connect fitting at the bottom of the barrel 201 can be connected to a valve or a material pipe, enabling targeted material discharge and ensuring a clean and tidy working environment.

[0077] This application optimizes the design of the mixing device, allowing the mixed putty to be extracted by the liquid pump 300 without affecting the mixing process. At the same time, the liquid pump 300 directly transports the mixed material to the grinding mill 400 for grinding. After grinding, the material can be mixed and ground again according to its fineness. Combining the two processes on one vehicle enables rapid material flow and reduces the time the material is exposed to air.
