Description

Technical Field

[0001] The invention relates to the technical field related to building spraying equipment, and in particular to a building material mixing spraying device and method based on extraction and stirring. Background Art

[0002] The building material mixing and spraying device is a device used to mix and spray a variety of building materials onto the building surface. This type of device usually includes a mixing box, a nozzle, a support column, a material receiving funnel and other components, which can achieve efficient mixing and spraying of different materials. The working principle of the mixing and spraying device is to introduce materials of different components into different separated areas respectively, and then through the action of the driving motor and the hydraulic cylinder, various coatings are impacted into the mixing barrel under high-speed rotation, and are fully stirred by the stirring blades to form a uniform mixture. This device can handle various types of building materials, such as cement, sand, aggregate, etc., and achieve precise control of the mixture by adjusting the operation of the nozzle.

[0003] Before spraying on building walls, cement mortar and other building materials need to be stirred continuously to ensure the uniformity and fluidity of the cement mortar. In existing building material mixing and spraying devices, the mixed mortar is generally directly pumped to the nozzle, which causes bubbles to easily appear on the wall after spraying, affecting the overall appearance of the wall. In addition, the contact area between the mixing blades in the mixing tank and the mortar cannot be adjusted as the amount of mortar changes, resulting in an increase in the power consumed by the mixing blades.

[0020] A method for mixing and spraying building materials based on extraction and stirring, using any one of the above-mentioned building material mixing and spraying devices based on extraction and stirring, comprising the following steps:

[0021] Step 1: First, pour an appropriate amount of mortar into the mixing tank, and start the servo motor and pumping mechanism to work simultaneously;

[0022] Step 2: When the servo motor is working, the flipping structure is controlled to stir the mortar in the mixing tank, and the mortar is squeezed by the flipping structure so that the mortar passes through the sieve holes and is thrown into the storage tank, so that the pumping mechanism extracts more fine and uniform mortar from the storage tank;

[0023] Step 3: When the stirring shaft rotates, it drives the movable shaft to make a circular motion in the storage tank, and the movable shaft itself rotates, so that the scraper rotates relative to the inner wall of the storage tank and moves back and forth up and down along the inner wall of the storage tank, always maintaining an abutting state;

[0024] Step 4: When the stirring shaft rotates, the threaded pusher is driven to work to push the connecting sleeve to move in a direction parallel to the axis of the transmission shaft. With the cooperation of the limit groove, the clearance rotation of the transmission shaft is realized to control the inclination of the flip structure while changing the inclination angle of the flip structure.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] When the stirring shaft is driven to rotate, the stirring blades are controlled to mix the mortar in the stirring tank. At the same time, the mortar is squeezed by the stirring blades so that the mortar is thrown into the storage tank through the sieve holes, so that the bubbles generated in the process of stirring the mortar are effectively removed, avoiding the formation of honeycomb-shaped small holes during the spraying process of the building wall, thereby affecting the appearance of the building wall. The bubbles and impurities can be effectively filtered out through the sieve holes, making the mortar more delicate and uniform, and improving the aesthetics of the wall spraying;

[0027] When the stirring shaft is driven to rotate, the movable shaft is driven to revolve and rotate at the same time, so that the sleeve revolves relative to the inner wall of the storage tank and moves back and forth up and down. During this process, the scraper always contacts and maintains line contact with the inner wall of the storage tank. On the one hand, the mortar adhered to the inner wall of the storage tank can be effectively scraped off, ensuring that the material on the inner wall of the tank body is cleaned in time. On the other hand, the close contact between the scraper and the inner wall of the storage tank reduces the accumulation of mortar on the inner wall of the storage tank, reduces the risk of pollution caused by material accumulation, avoids adhesion and agglomeration, and thus reduces the difficulty of cleaning.

[0028] When the stirring shaft is driven to rotate, the screw rod is driven to rotate synchronously. Under the action of the screw rod, the connecting sleeve moves downward in a direction parallel to the axis of the screw rod. When the connecting sleeve moves downward, the second ball and the limit groove cooperate to realize the gap rotation of the transmission shaft. Under the action of the first belt, the gap deflection action of the transfer shaft is controlled to allow the stirring blade to deflect, thereby changing the inclination angle of the stirring blade. When the amount of mortar in the mixing tank decreases, the inclination angle of the stirring blade increases, ensuring that different building materials are fully mixed in the mixing tank, while reducing the resistance borne by the stirring blade, and further reducing the power consumed by the stirring blade.

DETAILED DESCRIPTION

[0043] Various exemplary embodiments, features and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0044] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0045] In addition, in order to better illustrate the present application, numerous specific details are provided in the specific embodiments below. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0046] The present invention aims to propose a method for mixing and spraying building materials based on extraction and stirring, specifically a device for mixing and spraying building materials based on extraction and stirring, which ensures that different building materials are fully mixed in a mixing tank, and the power consumed by the mixing blades can be adjusted as the amount of mortar changes. The specific implementation method is as follows:

[0047] See also Figures 1 to 13 In an embodiment of the present invention, a construction material mixing and spraying device based on extraction and stirring includes a movable vehicle body 1;

[0048] The vehicle body 1 is provided with a storage tank 2, a stirring tank 5 is axially arranged inside the storage tank 2, and the storage tank 2 is communicated with the inner side of the stirring tank 5;

[0049] It also includes a stirring assembly rotatably disposed in the stirring tank 5, wherein the stirring assembly includes a stirring shaft 6 disposed in a hollow manner and a plurality of groups of flip structures rotatably disposed along the radial direction of the stirring shaft 6, and the flip structures are rotatably connected to a rotating shaft 9 disposed in the stirring shaft 6;

[0050] An intermittent adjustment member, mounted on the vehicle body 1 and connected to the central shaft 9, to control the stirring angle inclination and gap change of the flip structure;

[0051] The reciprocating scraper is disposed in the storage tank 2 , connected to the stirring shaft 6 , and abuts against the inner wall of the storage tank 2 and maintains linear contact.

[0052] In detail, when the stirring assembly stirs the building mortar in the mixing tank 5, while ensuring that the mortar is fully stirred, the flipping structure squeezes the mortar so that the mortar is thrown out of the mixing tank 5. At the same time, driven by the stirring shaft 6, the reciprocating scraper makes a circular motion relative to the inner wall of the storage tank 2, and reciprocates in a direction parallel to the axis of the stirring shaft 6, always abutting against and maintaining line contact with the inner wall of the storage tank 2, effectively scraping off the mortar adhered to the inner wall of the storage tank 2, and reducing the friction between the reciprocating scraper and the inner wall of the storage tank 2. Among them, under the action of the gap adjustment member, the inclination angle of the flipping structure is changed, so that when the amount of mortar in the mixing tank 5 is reduced, the inclination angle of the flipping structure is increased, ensuring that different building materials are fully mixed in the mixing tank 5, while reducing the resistance borne by the flipping structure, and further reducing the power consumed by the flipping structure.

[0053] It should be additionally explained that a hopper is also provided at the front end of the vehicle body 1, and the hopper is used to store part of the raw materials to increase the storage space.

[0054] As a further solution of the present invention, please refer to Figure 5A receiving seat 3 is fixedly provided at the tank mouth of the storage tank 2, and a driving shaft 17 is rotatably provided on the receiving seat 3. The driving shaft 17 is driven to rotate by a servo motor 16 fixedly installed on the receiving seat 3, and the driving shaft 17 is rotatably connected to the stirring shaft 6 through a bevel gear set 18.

[0055] One end of the stirring shaft 6 is rotatably connected to the bottom of the stirring tank 5 , and the other end is rotatably connected to the receiving seat 3 .

[0056] When the servo motor 16 is started, the output shaft of the servo motor 16 is fixedly connected to the drive shaft 17 so that the output shaft rotates to drive the drive shaft 17 to rotate synchronously, and the stirring shaft 6 is rotated under the transmission of the bevel gear set 18.

[0057] As a further solution of the present invention, please refer to Fig. 9 The flip structure includes a deflection shaft 7 which is arranged to rotate radially along the stirring shaft 6. A first bevel gear 701 is arranged at one end of the deflection shaft 7 which passes through the stirring shaft 6. The first bevel gear 701 is meshed with a second bevel gear 901 arranged on the rotating shaft 9. A stirring blade 8 is arranged at the other end of the deflection shaft 7.

[0058] Preferably, a plurality of sieve holes 501 are arranged along the circumference of the stirring tank 5 .

[0059] When the stirring shaft 6 rotates, it drives the multiple flipping structures to perform circular motion synchronously in the stirring tank 5, wherein the stirring blades 8 rotate in the stirring tank 5 to stir the building mortar in the stirring tank 5, thereby ensuring that the mortar is fully mixed while preventing the mortar from solidifying. The stirring blades 8 squeeze the mortar so that the mortar can be thrown into the storage tank 2 through the sieve holes 501. In the process of stirring the mortar, bubbles are easily generated. If these bubbles are not removed, small honeycomb-shaped holes are easily formed during the spraying process on the building wall, affecting the appearance of the building wall. The sieve holes 501 can effectively filter out bubbles and impurities, making the mortar more delicate and uniform.

[0060] As a further solution of the present invention, please refer to Figure 8 , Fig. 9 and Fig.11 The reciprocating scraper includes a connecting plate 10 rotatably disposed in the storage tank 2, and one end of the connecting plate 10 away from the inner wall of the storage tank 2 is fixed to the stirring shaft 6;

[0061] It also includes a movable shaft 11, which is arranged in a direction parallel to the axis of the stirring shaft 6. The movable shaft 11 is rotatably connected to the connecting plate 10. A first gear 12 is arranged on the movable shaft 11. The first gear 12 is meshed with the annular gear 4 arranged on the inner wall of the storage tank 2. A cleaning structure is slidably arranged on the movable shaft 11.

[0062] The cleaning structure includes a sleeve 14 axially arranged along the movable shaft 11, and a scraper 15 is detachably mounted on the sleeve 14. The scraper 15 abuts against the inner wall of the storage tank 2 and maintains linear contact. A first ball 1401 is movably arranged on the inner ring of the sleeve 14, and the first ball 1401 is slidably matched with a slide groove 1101 formed on the movable shaft 11.

[0063] Preferably, the slide groove 1101 includes two spirally opposite grooves, and both ends of the grooves are connected.

[0064] Preferably, at least one set of guide rods 13 is fixedly disposed at the bottom of the connecting plate 10 . The guide rods 13 are disposed in a direction parallel to the axis of the movable shaft 11 . The guide rods 13 penetrate the sleeve 14 and are slidably connected to the sleeve 14 .

[0065] To elaborate, when the above-mentioned stirring shaft 6 rotates, under the action of the connecting plate 10, the movable shaft 11 is driven to make a circular motion in the storage tank 2 with the stirring shaft 6 as the center. When the movable shaft 11 revolves, the first gear 12 thereon transmits with the annular gear 4, so that the movable shaft 11 rotates while revolving. When the movable shaft 11 rotates, with the action of the first ball 1401 and the slide groove 1101, the sleeve 14 can reciprocate along the axial direction of the movable shaft 11. Under the action of the guide rod 13, the sleeve 14 can only reciprocate relative to the movable shaft 11. When the sleeve 14 moves, it drives the scraper 15 to scrape the inner wall of the storage tank 2, so that the mortar adhered to the inner wall of the storage tank 2 is effectively removed, avoiding the mortar retained on the inner wall of the storage tank 2 from condensing, which makes the subsequent cleaning work cumbersome.

[0066] Preferably, the scraper blade 15 moves in a reciprocating spiral in the storage tank 2, and is fixed to the sleeve 14 by bolt connection. Although the scraper blade 15 is always in line contact with the storage tank 2, long-term friction will cause wear of the scraper blade 15. The detachable installation method facilitates easy replacement of the scraper blade 15, ensuring that the mortar adhered to the inner wall of the storage tank 2 is effectively removed.

[0067] As a further solution of the present invention, please refer to Figure 8 and Fig.12The gap adjustment member includes a transmission shaft 19 rotatably arranged on the vehicle body 1, and the transmission shaft 19 is rotatably connected to the transfer shaft 9 through a first belt 22. A connecting sleeve 21 is sleeved on the transmission shaft 19, and a second ball 2101 is movably arranged on the inner ring of the connecting sleeve 21. The second ball 2101 is slidably matched with a limiting groove 1901 formed on the transmission shaft 19, and the movement of the connecting sleeve 21 is driven by a threaded pusher arranged on the vehicle body 1.

[0068] The threaded pusher includes a screw rod 20 rotatably disposed on the vehicle body 1 , the screw rod 20 is rotatably connected to the stirring shaft 6 via a second belt 23 , and the screw rod 20 is threadedly connected to an end of the connecting sleeve 21 away from the transmission shaft 19 .

[0069] Preferably, the limiting groove 1901 is divided into multiple sections, each section includes a strip groove and a threaded groove. When the second ball 2101 moves into the threaded groove, the transmission shaft 19 rotates. When the second ball 2101 moves into the strip groove, the transmission shaft 19 stops rotating to achieve gap rotation of the transmission shaft 19.

[0070] Specifically, when the above-mentioned stirring shaft 6 rotates, the screw rod 20 is driven to rotate under the transmission of the second belt 23. When the screw rod 20 rotates, it drives the connecting sleeve 21 to move in a direction parallel to the axis of the screw rod 20. When the connecting sleeve 21 moves, the second ball 2101 thereon cooperates with the limiting groove 1901, so that the transmission shaft 19 rotates in a gap. When the transmission shaft 19 rotates, it drives the transfer shaft 9 to rotate under the transmission of the first belt 22. When the transfer shaft 9 rotates, the deflection shaft 7 is deflected under the transmission of the first bevel gear 701 and the second bevel gear 901 to change the inclination angle of the stirring blade 8, ensuring that the stirring blade 8 fully stirs the mortar. At the same time, as the mortar in the mixing tank 5 decreases, the stirring rate of the stirring blade 8 changes, and the power consumed by the stirring blade 8 is relatively small.

[0071] It is worth noting that: the output shaft of the servo motor 16 rotates at a high speed. In order to prevent the screw 20 from rotating too fast, the transmission ratio between the screw 20 and the stirring shaft 6 must be changed. Under the action of the two large and small pulleys, the rotation speed of the screw 20 is reduced to achieve the gap rotation of the transmission shaft 19 to ensure that when the inclination angle of the stirring blade 8 changes, the mortar in the mixing tank 5 can be fully mixed.

[0072] A support frame 27 is fixedly mounted on the vehicle body 1 . To ensure the balance and stability of the screw rod 20 and the transmission shaft 19 , one end of the screw rod 20 and the transmission shaft 19 away from the vehicle body 1 is rotatably connected to the support frame 27 .

[0073] As a further solution of the present invention, please refer to Fig.13A pumping mechanism 25 is provided at the bottom of the vehicle body 1, and the pumping mechanism 25 includes an impeller assembly fixedly arranged in the vehicle body 1 and a second motor fixed to the impeller assembly. The impeller assembly is respectively provided with an output end and an input end, and the input end is communicated with the inner side of the storage tank 2 through a conduit 24, and the output end is communicated with an injection pipe 26 fixedly arranged on the vehicle body 1.

[0074] Preferably, the bottom of the storage tank 2 is provided with an outlet 201 communicating with the inner side, and one end of the conduit 24 away from the impeller assembly is communicated with the outlet 201 .

[0075] The impeller assembly includes three parts: blades, impeller shaft, and blade cover. The second motor starts working. Under the action of the conduit 24, the mortar in the storage tank 2 is transported to the injection pipe 26. Considering the inconsistent heights of the building walls, the injection pipe 26 is generally connected with an extended hose and a spray gun to speed up the complete spraying of the building walls and reduce the occurrence of bubbles on the wall.

[0076] A method for mixing and spraying building materials based on extraction and stirring, using any one of the above-mentioned building material mixing and spraying devices based on extraction and stirring, comprising the following steps:

[0077] Step 1: First, pour an appropriate amount of mortar into the mixing tank 5, and start the servo motor 16 and the pumping mechanism 25 to work simultaneously;

[0078] Step 2: When the servo motor 16 is working, the flipping structure is controlled to stir the mortar in the mixing tank 5, and the mortar is squeezed by the flipping structure so that the mortar passes through the sieve hole 501 and is thrown into the storage tank 2, so that the pumping mechanism 25 extracts more fine and uniform mortar from the storage tank 2;

[0079] Step 3: When the stirring shaft 6 rotates, the movable shaft 11 is driven to make a circular motion in the storage tank 2, and the movable shaft 11 itself rotates, so that the scraper 15 rotates relative to the inner wall of the storage tank 2 and reciprocates up and down along the inner wall of the storage tank 2, always maintaining an abutting state;

[0080] Step 4: When the stirring shaft 6 rotates, the threaded pusher is driven to work to push the connecting sleeve 21 to move in a direction parallel to the axis of the transmission shaft 19. With the cooperation of the limiting groove 1901, the transmission shaft 19 is rotated in a gap to control the inclination of the flip structure while changing the inclination angle of the flip structure.

[0081] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and range of equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0082] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
