Description

Technical Field

[0001] The invention relates to the technical field of spraying equipment, and in particular to an auxiliary spraying device for building construction. Background Art

[0002] During construction, mortar needs to be sprayed onto the walls of buildings to carry out plastering operations, which is called "machine spray" plastering in the industry. Therefore, mortar-assisted spraying equipment is often needed to quickly load the walls to improve the efficiency of plastering operations. Mortar spraying equipment can be used for wall roughening spraying, bridge grouting and waterproof surface spraying, fireproof spraying, ceiling spraying, paint spraying, cement mortar grouting, garden spraying, handicraft spraying, waterproof plugging, etc., and is widely used.

[0003] Most of the existing mortar spraying machines use an electric motor to drive the screw to rotate, and then the mortar enters the sealed chamber formed between the screw and the feed pump. Every time the screw rotates one circle, the mortar in the sealed chamber advances one pitch. With the continuous rotation of the screw, the mortar is pressed from one sealed chamber to another in a spiral manner, and then squeezed out of the feed pump, so that the mortar squeezed out of the feed pump is sprayed onto the wall through the pipe, thereby achieving rapid spraying of the wall. However, since some larger stones will be mixed in the mixed mortar, the large stones may enter the feed pump along with the mortar, causing blockage in the feed pump and affecting the quality of mortar spraying. Summary of the invention

[0004] The present invention proposes an auxiliary spraying device for construction to solve the problem that some large stones may be mixed into the mixed mortar, which may cause the large stones to enter the feed pump along with the mortar, causing blockage in the feed pump and affecting the mortar spraying quality.

[0005] In order to achieve the above-mentioned objectives, the present invention adopts the following technical scheme: an auxiliary spraying device for construction, comprising a body, a rotating wheel is arranged on one side of the body, a material delivery pipe is arranged on one side of the body, a controller is arranged on one side of the body, a feed hopper is arranged on one side of the material delivery pipe, a filtering device is arranged on one side of the feed hopper, the filtering device comprises a cylinder, a connecting device is arranged between the cylinder and the feed hopper, a protective device is arranged on one side of the cylinder, a filter cartridge is fixedly connected to the inner wall of the cylinder, a filter plate is fixedly connected to the inner wall of the filter cartridge, the filter plate is fixedly connected to the inner wall of the cylinder, a round hole rod is fixedly connected to one side of the round hole rod, a motor is fixedly connected to one side of the round hole rod, a round shaft is fixedly connected to the output end of the motor, the round shaft is arranged inside the round hole rod, a scraper is fixedly connected to the end of the round shaft away from the motor, the scraper is arranged inside the filter cartridge, and the surface of the scraper fits the inner wall of the filter cartridge.

[0006] The effects achieved by the above components are as follows: by setting up the filtering device, firstly, the cylinder is assembled and fixed with the feed hopper through the connecting device, at this time, the mortar is put into the cylinder and the motor is started, so that the mortar enters the filter cartridge from the cylinder, so that the motor drives the round shaft to rotate along the inside of the round hole rod, so that the round shaft drives the scraper to rotate along the inside of the filter cartridge, so that the scraper stirs the mortar inside the filter cartridge, so that the scraper uses its own multiple through holes to scrape off the large volume of stones mixed in the mortar, so that the mortar after the stones are scraped off passes through the filter cartridge and enters the filter plate combined with the filter plate. The mortar is then discharged from the cylinder through the filter plate and falls into the feed hopper, completing the separation and filtration of the mortar. After the mortar enters the cylinder, it can be quickly stripped of the gravel inside the mortar through multiple filtrations of the filter cylinder, scraper and filter plate and fall into the feed hopper, reducing the situation in which the mortar is put into the feed hopper and the large volume of gravel is mixed inside, causing the large volume of gravel to enter the feed pipe, causing blockage in the feed pipe and affecting the quality of mortar spraying, thereby improving the feeding safety of the feed pipe and the filtering efficiency of the mortar.

[0007] Preferably, a support plate is fixedly connected to one side of the circular shaft close to the scraper, the surface of the support plate is trapezoidal, and the support plate is fixedly connected to the scraper.

[0008] The effect achieved by the above-mentioned components is: by setting the support plate, the support plate can strengthen the connection between the circular shaft and the scraper, increase the connection strength between the circular shaft and the scraper, reduce the separation of the circular shaft when driving the scraper to rotate, improve the connection stability between the circular shaft and the scraper, and at the same time provide auxiliary support for the scraper, reduce the left or up and down shaking of the scraper on the side away from the circular shaft during use, and improve the stability of the scraper.

[0009] Preferably, a plurality of guide grooves are opened on one side of the filter cartridge, the plurality of guide grooves are arranged at equal distances, the inner wall cross-section of the guide grooves is triangular, and the inner walls of the plurality of guide grooves are connected to the inner wall of the filter cartridge.

[0010] The effect achieved by the above components is: by setting the guide grooves, the mortar that falls into the cylinder can flow into the filter cartridge through multiple guide grooves, reducing the accumulation of some mortar and the situation where it cannot smoothly enter the filter cartridge by remaining on the surface of the filter cartridge, improving the fluidity of the mortar on the surface of the filter cartridge, allowing the mortar to more smoothly enter the filter cartridge for the first filtration, and reducing the situation where mortar remains on the surface of the filter cartridge and inside the cylinder.

[0011] Preferably, a screw hole tube is fixedly connected to the inner wall of the filter cartridge, the inner wall of the screw hole tube passes through the filter cartridge, and the inner wall of the screw hole tube is threadedly connected to a threaded plate.

[0012] The effect achieved by the above components is as follows: by setting the screw hole tube and the threaded plate, first manually rotate the threaded plate. When the threaded plate is rotated to a position completely entering the interior of the screw hole tube, the threaded plate completely closes the inner wall of the screw hole tube to intercept the mortar inside the filter cartridge. After the scraper peels off a certain amount of stone, manually rotate the threaded plate again. When the threaded plate is rotated to a position completely out of the interior of the screw hole tube, the threaded plate contacts the closure of the screw hole tube. At this time, the stone peeled off by the scraper inside the filter cartridge can fall out through the inside of the screw hole tube, reducing the storage of the stone peeled off from the mortar by the scraper inside the filter cartridge. In addition, the deep space inside the filter cartridge is small, which makes it inconvenient for personnel to take out the stone, thereby improving the convenience and efficiency of personnel handling the stone stored inside the filter cartridge.

[0013] Preferably, a circular groove is provided on one side of the threaded plate, a screw block is fixedly connected to the inner wall of the circular groove, and a surface cross-section of the screw block is cross-shaped.

[0014] The effect achieved by the above components is: by setting the circular groove and the twist block, the twist block can provide a fulcrum for personnel when manually rotating the threaded plate, so that personnel can put their hands into the circular groove and rotate the twist block, so that the twist block drives the threaded plate to rotate quickly, reducing the situation where the hands slip when personnel manually rotate the threaded plate due to the relatively smooth surface of the threaded plate, improving the convenience and stability of personnel manually rotating the threaded plate, and facilitating personnel to quickly handle the stones inside the filter cartridge.

[0015] Preferably, the connecting device includes a rectangular cylinder, which is fixedly connected to the feed hopper, a threaded hole is provided on one side of the rectangular cylinder, and a bolt is threadedly connected to the inner wall of the threaded hole, an L-shaped rod is fixedly connected to one side of the cylinder, the surface of the L-shaped rod is slidably connected to the inner wall of the rectangular cylinder, a circular hole is provided on one side of the L-shaped rod, and the surface size and shape of the bolt are adapted to the size and shape of the inner wall of the circular hole.

[0016] The effect achieved by the above components is: by setting the connecting device, the cylinder is first moved manually so that the cylinder drives the L-shaped rod to move. When the cylinder moves to a position that fits the surface of the feed hopper, the L-shaped rod is inserted into the rectangular cylinder so that the inner wall of the circular hole coincides with the inner wall of the threaded hole. At this time, the bolt is manually rotated so that the bolt is rotated into the threaded hole and the inner position of the circular hole to fix the position of the L-shaped rod inside the rectangular cylinder, so that the position of the cylinder is fixed, thereby completing the rapid assembly of the cylinder and the feed hopper. At the same time, the filter device can be quickly separated from the feed hopper at a later stage, reducing the inconvenience of personnel in transporting and storing the machine body due to the inability of personnel to separate the cylinder from the feed hopper, and improving the convenience and efficiency of personnel in maintaining and replacing the filter device at a later stage.

[0017] Preferably, one end of the bolt is fixedly connected to an operating block, and a plurality of grooves are formed on the surface of the operating block.

[0018] The effect achieved by the above-mentioned components is: by setting the operating block, the operating block can increase the contact area of ​​the bolt, so that personnel can drive the bolt to be easily rotated by manually turning the operating block, thereby improving the convenience of manually turning the bolt; at the same time, under the action of multiple grooves, the multiple grooves can increase the friction between the hand and the surface of the operating block, thereby reducing the situation where the personnel's hands slip when manually turning the operating block.

[0019] Preferably, a reinforcement block is fixedly connected to one side of the L-shaped rod close to the cylinder, the reinforcement block is fixedly connected to the cylinder, and the surface of the reinforcement block is trapezoidal.

[0020] The effect achieved by the above components is: by setting the reinforcement block, the reinforcement block can strengthen the connection between the L-shaped rod and the cylinder, reduce the separation between the L-shaped rod and the cylinder during use, improve the connection stability between the L-shaped rod and the cylinder, and further strengthen the connection stability between the cylinder and the feed hopper.

[0021] Preferably, the protective device includes a circular hole block, which is fixedly connected to the cylinder, and the inner wall of the circular hole block is rotatably connected to a round rod, one end of the round rod is fixedly connected to a connecting frame, one side of the connecting frame is fixedly connected to a protective plate, the surface of the protective plate is semicircular, and one side of the protective plate is fixedly connected to a handle, and a plurality of anti-slip protrusions are provided on the inner side of the handle.

[0022] The effect achieved by the above-mentioned components is: by setting the protective device, first manually move the handle so that the handle drives the protective plate to rotate, so that the protective plate drives the connecting frame to rotate, and so that the connecting frame drives the round rod to rotate along the inside of the circular hole block. When the protective plate rotates to a position that fits the surface of the cylinder opening, the protective plate seals the opening position of the cylinder and intercepts external dust and impurities, thereby reducing the amount of external dust and impurities entering the cylinder and accumulating when the filter device is idle, causing subsequent mortar to be put into the cylinder and then merge with the dust and impurities, affecting the spraying quality of the mortar, and improving the cleanliness and dustproofness of the cylinder when it is idle.

[0023] Preferably, a plurality of reinforcing ribs are fixedly connected to one side of the protective plate, the plurality of reinforcing ribs are arranged at equal distances, and the surfaces of the reinforcing ribs are arc-shaped.

[0024] The effect achieved by the above components is: by setting reinforcing ribs, the reinforcing ribs can increase the strength of the protective plate, reduce the collision of the protective plate with external objects, and cause the protective plate to break or deform, thereby improving the protective strength and self-strength of the protective plate and increasing the service life of the protective plate.

[0025] In summary, the beneficial effects of the present invention are:

[0026] By setting up a filtering device, the mortar can be filtered multiple times and the stones inside the mortar can be quickly peeled off, reducing the situation where the mortar is put into the feed hopper and the large volume of stones are mixed inside, causing the large volume of stones to enter the feed pipe, causing blockage in the feed pipe and affecting the mortar spraying quality, thereby improving the feeding safety of the feed pipe and the filtering efficiency of the mortar.

[0027] By setting up a connecting device, the filter device can be quickly separated and assembled, reducing the inconvenience of personnel transporting and storing the machine body due to the inability of personnel to separate the cylinder from the feed hopper, and improving the convenience and efficiency of personnel in maintaining and replacing the filter device in the later stage.

[0028] By setting up a protective device, the opening position of the cylinder can be closed and external dust and impurities can be intercepted, thereby reducing the risk of external dust and impurities entering the cylinder and accumulating when the filtering device is idle, causing subsequent mortar to be put into the cylinder and merge with the dust and impurities, affecting the spraying quality of the mortar, and improving the cleanliness and dust resistance of the interior of the cylinder when it is idle.
