Description

Technical Field

[0001] This utility model relates to the field of building engineering, and in particular to spraying equipment for the construction of exterior wall insulation layers. Background Technology

[0002] Spraying equipment is a type of machinery specifically designed for spraying insulation materials onto the exterior walls of buildings. Its main function is to spray insulation materials in liquid or semi-liquid form onto the surface of the building exterior walls to form a uniform insulation layer. This equipment is typically characterized by high efficiency, speed, and uniform spraying, enabling it to complete large-area insulation construction in a short time and ensuring that the thickness and quality of the insulation layer meet design requirements.

[0003] In the spraying construction of exterior wall insulation layers, commonly used insulation materials are mostly multiphase composite systems, containing components such as lightweight particles, fibers, fillers, and matrix materials. Due to the large density differences among the components, during the storage and transportation process in the feed hopper of traditional spraying equipment, precipitation and separation phenomena such as particle settling, fiber agglomeration, and solid-liquid stratification can easily occur due to static placement or gravity. This can lead to uneven material concentration during spraying, resulting in fluctuations in the thermal insulation performance of the coating, poor surface smoothness, and seriously affecting construction efficiency and project quality. Utility Model Content

[0004] The technical problem this utility model aims to solve is that in the spraying construction of exterior wall insulation layers, commonly used insulation materials are mostly multiphase composite systems, containing components such as lightweight particles, fibers, fillers, and matrix materials. Due to the large density differences among the components, during the storage and transportation process in the feed hopper of traditional spraying equipment, precipitation and separation phenomena such as particle settling, fiber agglomeration, and solid-liquid stratification easily occur due to static placement or gravity. This leads to uneven material concentration during spraying, causing fluctuations in the thermal insulation performance of the coating and a decrease in surface smoothness, which seriously affects construction efficiency and project quality.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a spraying equipment for the construction of thermal insulation layer of building exterior walls, including a screw conveyor, a feed hopper fixedly installed on the outer surface of the screw conveyor, a spray pipe fixedly installed at the outlet of the screw conveyor, a spray gun fixedly installed at one end of the spray pipe, and a stirring device provided on one side of the feed hopper. The stirring device can drive a round rod, several grooved blocks and ball bearings to stir in the feed hopper by a servo motor, and at the same time can knock and vibrate the inner wall of the feed hopper, so that the thermal insulation material is not easy to settle and delaminate in the feed hopper.

[0006] Preferably, the stirring device includes a support and several grooved blocks, with a mounting mechanism provided between both ends of the support and both sides of the feed hopper; a servo motor, one side of which is fixedly mounted on one side of the support; a round rod, one end of which is installed through one side of the support, and the other side is fixedly connected to the output end of the servo motor via a coupling; an auxiliary mechanism, which is disposed between the outer surfaces of the several grooved blocks and the round rod, for driving the grooved blocks to move back and forth during the stirring process; and several ball bearings, which are rotatably installed in the inner wall of the grooved blocks.

[0007] The aforementioned components achieve the following effects: By setting up a mixing device, during the construction of the insulation layer on the exterior wall of a building, the insulation material is poured into the feeding hopper. Then, the drive motor on the screw conveyor is started to drive the internal threaded conveying rod to transport the insulation material in the feeding hopper to the spray nozzle. The material is then sprayed onto the exterior wall of the building by the spray gun to form an insulation layer. After the insulation material is placed in the feeding hopper, the servo motor can be started to drive the round rod to rotate on the support. Then, in conjunction with the auxiliary mechanism, several grooved blocks and balls move in a circular motion in the feeding hopper, while simultaneously moving back and forth and striking the inner wall of the feeding hopper, causing the feeding hopper to vibrate. This effectively prevents the insulation material from settling and delaminating in the feeding hopper, ensuring the uniformity of the insulation material and helping to improve the construction quality and efficiency of the exterior wall insulation layer.

[0008] Preferably, the auxiliary mechanism includes two abutment rods, one side of which is fixedly mounted on one side of the bracket; several grooved rods, one side of which is fixedly mounted on the outer surface of the round rod; several sliding rods, one end of which is slidably mounted in the inner wall of the grooved rod, and the other end of which is fixedly mounted on the outer surface of the grooved block; several springs, the two ends of which are respectively fixedly mounted on one side of the sliding rod and one side of the inner wall of the grooved rod; and several abutment brackets, one side of which is installed through the outer surface of two parallel sliding rods, and one end of which abuts against one end of the abutment rod.

[0009] The effect achieved by the above components is as follows: By setting up an auxiliary mechanism, after the round rod rotates to a certain angle, it will drive the grooved rod, the sliding rod, and the abutment frame to rotate in a circle. When it rotates to a certain position, one end of the abutment frame will abut against one end of the abutment rod, causing the sliding rod to slide inward in the inner wall of the grooved rod, causing its spring to contract. After the grooved block and the ball are away from the inner wall of the feed hopper, the abutment frame is completely removed from the abutment rod, and the spring will drive the sliding rod to reset, thereby causing the grooved block and the ball to strike the inner wall of the feed hopper, causing it to vibrate, further enhancing the vibration effect on the feed hopper, more effectively preventing the insulation material from settling and delaminating, ensuring the uniformity of the material, and thus helping to improve the construction quality and efficiency of the external wall insulation layer.

[0010] Preferably, an auger plate is fixedly installed on the outer surface of one end of the round rod, and the auger plate is located on the end of the round rod away from the servo motor.

[0011] The effect achieved by the above components is that by setting up the auger plate, the outlet of the feed hopper can be agitated to achieve the effect of preventing blockage.

[0012] Preferably, a protective cover is fixedly installed on one side of the bracket, and the servo motor is disposed in the inner wall of the protective cover.

[0013] The effect achieved by the above components is that by setting up a protective cover, the outer surface of the servo motor can be protected, making it less likely to be hit during use, avoiding damage, and increasing its service life.

[0014] Preferably, the casual clothing mechanism includes a locking block, wherein the inner wall of the locking block is fitted onto the outer surface of the edge of the feed hopper, and locking holes are provided on both sides of the inner wall of the feed hopper; and an elastic block, wherein one side of the elastic block is fixedly installed on one side of the locking block, and the elastic block is inserted into the inner wall of the locking hole.

[0015] The effect achieved by the above-mentioned components is as follows: after the insulation material is poured into the feeding hopper, the round rod can be inserted into the feeding hopper, and then the locking blocks on both ends of the bracket can be respectively fitted onto the outer surface of the edge of the feeding hopper, so that one side of the elastic block abuts against one side of the feeding hopper and deforms. After pressing the locking block to a certain position, the elastic block will reset and lock into the locking hole, thereby fixing the bracket on the feeding hopper. Similarly, it can also be disassembled for easy replacement and maintenance.

[0016] Preferably, limit blocks are symmetrically fixedly installed on both sides of the feed hopper, wherein the locking block is inserted between the two opposite limit blocks.

[0017] The effect achieved by the above components is that, by setting the limiting blocks, when the card block is sleeved on the outer surface of the feed hopper, it can be inserted between two opposite limiting blocks, so that the elastic block can be quickly aligned with the card hole, which is convenient for installation.

[0018] Preferably, both ends of the card block are chamfered.

[0019] The effect achieved by the above components is that by setting chamfers, the area at both ends of the locking block can be reduced, making it easier to quickly lock into the two opposing limiting blocks and facilitating installation.

[0020] The beneficial effects of this utility model are:

[0021] By installing a mixing device, during the construction of the insulation layer on the exterior wall of a building, the insulation material is poured into the feeding hopper. Then, the drive motor on the screw conveyor is started, which drives the internal threaded conveying rod to transport the insulation material from the feeding hopper to the spray nozzle. The material is then sprayed onto the exterior wall of the building by the spray gun to form an insulation layer. After the insulation material is placed in the feeding hopper, a servo motor can be started to drive the round rod to rotate on the support. Then, in conjunction with the auxiliary mechanism, several grooved blocks and balls move in a circular motion in the feeding hopper, while simultaneously moving back and forth and striking the inner wall of the feeding hopper. This causes the feeding hopper to vibrate, effectively preventing the insulation material from settling and delaminating in the feeding hopper, ensuring the uniformity of the insulation material, and helping to improve the construction quality and efficiency of the exterior wall insulation layer.

[0032] Figure 1-6 The spraying equipment for building exterior wall insulation layer construction shown includes a screw conveyor 1, a feed hopper 3 fixedly installed on the outer surface of the screw conveyor 1, a spray pipe 4 fixedly installed at the outlet of the screw conveyor 1, and a spray gun 5 fixedly installed at one end of the spray pipe 4. A stirring device 2 is provided on one side of the feed hopper 3. The stirring device 2 can drive a round rod 24, several grooved blocks 25, and ball bearings 26 to stir in the feed hopper 3 through a servo motor 23. At the same time, it can also tap and vibrate the inner wall of the feed hopper 3 to prevent the insulation material from settling and delaminating in the feed hopper 3. It should be noted that the screw conveyor 1 and the spray gun 5 are mature technologies and equipment in the prior art, and their internal structure, connection method, and principle will not be described further.

[0033] Figure 1-6 The mixing device 2 shown includes a support 21 and several grooved blocks 25. A mounting mechanism 22 is provided between both ends of the support 21 and both sides of the feed hopper 3. A servo motor 23 is also included, with one side of the servo motor 23 fixedly mounted on one side of the support 21. A round rod 24 is also included, with one end of the rod penetrating and mounted on one side of the support 21, and the other side fixedly connected to the output end of the servo motor 23 via a coupling. An auxiliary mechanism 27 is provided between the grooved blocks 25 and the outer surface of the round rod 24, used to drive the grooved blocks 25 to move back and forth during the mixing process. Several ball bearings 26 are also included, rotatably mounted in the inner wall of the grooved blocks 25. By setting up a mixing device 2, when constructing the insulation layer on the exterior wall of a building, the insulation material is poured into the feeding hopper 3. Then, the drive motor on the screw conveyor 1 is started to drive the internal threaded conveying rod to transport the insulation material in the feeding hopper 3 to the spray pipe 4. Then, the spray gun 5 sprays it onto the exterior wall of the building to form an insulation layer. After the insulation material is placed in the feeding hopper 3, the servo motor 23 can be started to drive the round rod 24 to rotate on the bracket 21. Then, in conjunction with the auxiliary mechanism 27, several grooved blocks 25 and ball bearings 26 move in a circular motion in the feeding hopper 3, and move back and forth to strike the inner wall of the feeding hopper 3, causing the feeding hopper 3 to vibrate. This effectively prevents the insulation material from settling and delaminating in the feeding hopper 3, ensuring the uniformity of the insulation material and helping to improve the construction quality and efficiency of the exterior wall insulation layer.

[0034] Figure 1-6 The auxiliary mechanism 27 shown includes two abutment rods 271, one side of which is fixedly mounted on one side of the bracket 21; several grooved rods 272, one side of which is fixedly mounted on the outer surface of the round rod 24; several sliding rods 273, one end of which is slidably mounted in the inner wall of the grooved rod 272, and the other end is fixedly mounted on the outer surface of the grooved block 25; several springs 274, the two ends of which are respectively fixedly mounted on one side of the sliding rod 273 and one side of the inner wall of the grooved rod 272; and several abutment brackets 275, one side of which is installed through the outer surface of two parallel sliding rods 273, and one end abuts against one end of the abutment rod 271. By setting up auxiliary mechanism 27, after the round rod 24 rotates to a certain angle, it will drive the grooved rod 272, the sliding rod 273, and the abutment frame 275 to rotate in a circle. When it rotates to a certain position, one end of the abutment frame 275 will abut against one end of the abutment rod 271, causing the sliding rod 273 to slide inward in the inner wall of the grooved rod 272, causing its spring 274 to contract. The grooved block 25 and the ball 26 move away from the inner wall of the feed hopper 3. After the abutment frame 275 is completely removed from the abutment rod 271, the spring 274 will drive the sliding rod 273 to reset, thereby causing the grooved block 25 and the ball 26 to strike the inner wall of the feed hopper 3, causing it to vibrate, further enhancing the vibration effect on the feed hopper 3, more effectively preventing the insulation material from settling and delaminating, ensuring the uniformity of the material, and thus helping to improve the construction quality and efficiency of the external wall insulation layer. A screw conveyor plate 28 is fixedly installed on the outer surface of one end of the round rod 24. The screw conveyor plate 28 is located at the end of the round rod 24 away from the servo motor 23. By setting the screw conveyor plate 28, the outlet of the feed hopper 3 can be agitated to achieve the effect of preventing blockage. A protective cover 29 is fixedly installed on one side of the bracket 21, and the servo motor 23 is located in the inner wall of the protective cover 29. By setting the protective cover 29, the outer surface of the servo motor 23 can be protected, making it less likely to be hit during use, avoiding damage, and improving its service life.

[0035] Figure 1-6The illustrated device 22 includes a locking block 222, the inner wall of which is fitted onto the outer surface of the edge of the feed hopper 3, and locking holes 221 are provided on both sides of the inner wall of the feed hopper 3; and an elastic block 223, one side of which is fixedly installed on one side of the locking block 222, and the elastic block 223 is inserted into the inner wall of the locking hole 221. After the insulation material is poured into the feed hopper 3, the round rod 24 can be inserted into the feed hopper 3, and then the locking blocks 222 on both ends of the bracket 21 are fitted onto the outer surface of the edge of the feed hopper 3, so that one side of the elastic block 223 abuts against one side of the feed hopper 3 to deform it. After pressing the locking block 222 to a certain position, the elastic block 223 will return to its original position and lock into the locking hole 221, thereby fixing the bracket 21 to the feed hopper 3. Similarly, it can also be disassembled for easy replacement and maintenance.

[0036] Figure 1-6 The feed hopper 3 shown has symmetrically fixed limit blocks 224 on both sides, with a locking block 222 inserted between two opposing limit blocks 224. By setting the limit blocks 224, the locking block 222 can be inserted between the two opposing limit blocks 224 when it is fitted onto the outer surface of the feed hopper 3, allowing its elastic block 223 to quickly align with the locking hole 221, facilitating installation. Both ends of the locking block 222 have chamfers. By setting the chamfers, the area at both ends of the locking block 222 is reduced, making it easier to quickly engage between the two opposing limit blocks 224, facilitating installation.

[0037] Working principle: When constructing the insulation layer on the exterior wall of a building, the insulation material is poured into the feed hopper 3. Then, the drive motor on the screw conveyor 1 is started, driving the internal threaded conveying rod to transport the insulation material in the feed hopper 3 to the spray nozzle 4. Then, the spray gun 5 sprays it onto the exterior wall of the building to form an insulation layer. After the insulation material is placed in the feed hopper 3, the round rod 24 is first inserted into the feed hopper 3. Then, the locking blocks 222 on both ends of the bracket 21 are respectively fitted onto the outer edge surface of the feed hopper 3, so that one side of the elastic block 223 abuts against one side of the feed hopper 3, causing it to deform. Then, after the locking block 222 is pressed to a certain position, the elastic block 223 will reset and lock into the locking hole 221, thereby fixing the bracket 21 on the feed hopper 3. Then, the servo motor 23 is started to drive the round rod 24 to rotate on the bracket 21. 4. After rotating to a certain angle, the grooved rod 272, the sliding rod 273, and the abutment frame 275 will rotate in a circular motion. When the rotation reaches a certain position, one end of the abutment frame 275 will abut against one end of the abutment rod 271, causing the sliding rod 273 to slide inward in the inner wall of the grooved rod 272, causing the spring 274 to contract. The grooved block 25 and the ball 26 will move away from the inner wall of the feed hopper 3. After the abutment frame 275 is completely removed from the abutment rod 271, the spring 274 will drive the sliding rod 273 to reset, thereby causing the grooved block 25 and the ball 26 to strike the inner wall of the feed hopper 3, causing them to vibrate while being stirred. This further enhances the vibration effect on the feed hopper 3, effectively preventing the insulation material from settling and stratifying in the feed hopper 3, ensuring the uniformity of the insulation material, and helping to improve the construction quality and efficiency of the external wall insulation layer.
