Description

Technical Field

[0001] The invention relates to the technical field of concrete spraying machines, in particular to an anti-condensation concrete spraying machine. Background Art

[0002] Concrete is a general term for a composite material made of stone, sand and water in a certain proportion. As a gel material, concrete is widely used in construction. After the concrete is made, it can be sprayed directly on the surface of the building through the corresponding concrete sprayer. The residual material inside the machine is prone to solidification, affecting the actual spraying effect.

[0003] For example, a concrete spraying machine for preventing residual material from solidifying, which is published as CN216552908U, comprises a bearing box, the bearing box is fixedly connected to the upper end of a fixed plate which is in a horizontal state and used for bearing, a mounting plate, the mounting plate is used for stirring the concrete inside the bearing box, a limiting mechanism, the limiting mechanism drives the scraper to be disassembled inside the bearing box, and a mounting column, the mounting column is used for installing a booster pump and a spraying pipeline. The device can prevent the residual concrete inside the bearing box from solidifying, and at the same time, combined with the arrangement of the scraper, it is convenient to scrape off the concrete attached to the inner wall of the bearing box, and it is convenient to remove the scraper. The installation column and the fixing sleeve can be installed to disassemble and clean the injection pipe very conveniently after use to prevent the injection pipe from being blocked. However, it is not convenient to add water to the inside of the concrete only by stirring to prevent solidification, so the anti-solidification effect is relatively general. Solidification may still occur, which will affect the subsequent normal spraying and use of the concrete. The method of directly adding water through a water pipe in the prior art is not convenient for controlling the amount of water added. For the prepared concrete material, if too much water is added, the strength of the concrete will be reduced, which may affect the subsequent construction effect. Therefore, the method of directly adding water through a water pipe also has limitations.

[0004] So we proposed a kind of anti-condensation concrete spraying machine, in order to solve the above-mentioned problem. Summary of the invention

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows: a water replenishing mechanism is provided, and by starting the motor to rotate, the motor drives the rotating shaft to rotate, so that the push rod squeezes the abutment block, and a gap appears between the abutment block and the bottom groove, and water will spray out from the gap between the abutment block and the bottom groove, thereby realizing intermittent water replenishment and the water replenishment point can be adjusted by self-sliding, which is convenient for replenishing water to concrete and avoids the influence of excessive water replenishment on the strength of concrete. Through the cooperation of the water replenishment mechanism and the stirring mechanism, the anti-solidification effect of concrete is improved; 1. A water replenishment mechanism is provided. Concrete material is added into the lower bin through the feed pipe, and then the concrete material inside the lower bin is pumped out through the injection pipe by the injection pump for use. At the same time, in order to prevent the concrete inside the lower bin from solidifying and clogging, the motor is started to rotate, the motor drives the rotating shaft to rotate, and the rotating shaft drives the fixed sleeve and the push rod to rotate.

[0030] Embodiment 1: Figure 1-2 and Figure 4-6 As shown, first, concrete material is added into the lower bin body 3 through the feed pipe 12, and then the concrete material inside the lower bin body 3 is pumped out through the injection pipe 11 by the injection pump 10 for use. At the same time, in order to prevent the concrete inside the lower bin body 3 from solidifying and clogging, by starting the motor 14 to rotate, the motor 14 drives the rotating shaft 15 to rotate, and the rotating shaft 15 drives the fixed sleeve 16 and the push rod 17 to rotate. When the push rod 17 rotates to the position of the abutment block 29, the abutment block 29 will be squeezed, and the abutment block 29 will slide on the slide bar 28 and compress the compression spring 31, and a gap will appear between the abutment block 29 and the bottom groove 30.

[0031] At this time, the pressure pump 6 pumps the water in the water tank 5 into the drain pipe 8, and then flows into the telescopic tube 25 through the drain pipe 8. The water will spray out from the gap between the abutment block 29 and the bottom groove 30. Then the push rod 17 continues to push the abutment block 29 and the fixed cylinder 27 to move. The fixed cylinder 27 drives the slider 23 to slide on the guide rod 22. The slider 23 moves to stretch the reset spring 26. The telescopic tube 25 can be telescopically adapted to the movement of the slider 23 until the slider 23 abuts against the end of the limit plate 19. The abutment block 29 is an elastic block.

[0032] In combination with the arc at the bottom of the abutment block 29, the push rod 17 is separated from the abutment block 29 and continues to rotate, and the stretched reset spring 26 drives the slider 23 to reset, so that the abutment block 29 is reset to the initial position, realizing intermittent water replenishment and the water replenishment point can be adjusted by autonomous sliding, which is convenient for replenishing water to the concrete and avoids the influence of excessive water replenishment on the strength of the concrete. It solves the problem that only stirring is used to prevent the solidification of concrete, but it is not convenient to add water to the inside, so that the anti-solidification effect is relatively general. In addition, the existing method of directly adding water through a water pipe will affect the strength of the concrete when too much water is added.

[0033] The stirring mechanism is arranged inside the lower bin body 3, and the stirring mechanism includes a scraping rod 33, a mounting sleeve 34, a mounting plate 1 39, a protrusion 40 and a mounting plate 2 41.

The end of the stirring rod 35 away from the mounting sleeve 34 is fixedly connected to the scraping rod 33.

[0034] The mounting sleeves 34 are evenly arranged, with no less than two mounting sleeves 34 , the stirring rods 35 are arranged in an array on the outside of the mounting sleeves 34 , with no less than three stirring rods 35 , the number of the scraping rods 33 matches the stirring rods 35 , and sliding blocks 37 are symmetrically fixed on the outside of the rotating shaft 15 .

[0035] The scraping rod 33 fits against the inner wall of the lower bin body 3, and a vertical groove 36 is symmetrically and vertically opened on the inner side of the mounting sleeve 34. The sliding block 37 is located inside the vertical groove 36, and the sliding block 37 is slidably connected to the vertical groove 36. An auxiliary spring 38 is fixedly connected to the bottom surface of the vertical groove 36, and the top of the auxiliary spring 38 is fixedly connected to the bottom of the sliding block 37.

[0036] The mounting plate 1 39 is located at the top of the mounting sleeve 34 , the mounting plate 2 41 is located at the bottom of the mounting sleeve 34 , and the bottom of the mounting plate 1 39 is fixedly connected with a protrusion 40 , which is distributed in an array and has no less than four protrusions 40 .

[0037] A protrusion 40 is fixedly connected to the top of the second mounting plate 41 , and the projection positions of the top protrusion 40 and the bottom protrusion 40 differ by 45 degrees. Inclined blocks are symmetrically fixed on both sides of the protrusion 40 , and the cross-section of the inclined blocks is a triangle.

[0038] Embodiment 2: Figure 3 and Figure 7-10 As shown, a stirring mechanism is provided. When the motor 14 drives the rotating shaft 15 to rotate, the rotating shaft 15 drives the sliding block 37 on the outer side of the lower part to rotate, the sliding block 37 drives the mounting sleeve 34 to rotate, and the mounting sleeve 34 drives the stirring rod 35 and the scraping rod 33 to rotate. The rotation of multiple stirring rods 35 stirs the concrete inside, and cooperates with the water replenishment on the top to reduce the solidification of the concrete. At the same time, the scraping rod 33 scrapes the inner wall of the lower warehouse body 3 to reduce the adhesion of the concrete to the inner wall of the lower warehouse body 3. When the stirring rod 35 rotates, when the stirring rod 35 moves to the position of the protrusion 40 on the mounting plate 39, due to the lifting of the protrusion 40 , so that the stirring rod 35 drives the scraping rod 33 and the mounting sleeve 34 to rise a certain distance, the auxiliary spring 38 is used to reset the mounting sleeve 34, and the position of the protrusion 40 on the mounting plate 41 is at an angle to the position of the protrusion 40 on the mounting plate 1 39, so that the protrusion 40 on the mounting plate 1 39 rotates forty-five degrees to correspond to the protrusion 40 on the mounting plate 2 41, so that when the top of the stirring rod 35 is squeezed by the protrusion 40, the bottom is not squeezed, and through the lifting cooperation of the protrusions 40 on the mounting plate 1 39 and the mounting plate 2 41, it is easy to realize the up and down movement of the stirring rod 35 and the scraping rod 33 when stirring, thereby improving the stirring effect.

[0039] Working principle: When using the device, first, Figure 1-10As shown, first, concrete material is added into the lower bin body 3 through the feed pipe 12, and then the concrete material inside the lower bin body 3 is pumped out through the injection pipe 11 by the injection pump 10 for use. At the same time, in order to prevent the concrete inside the lower bin body 3 from solidifying and clogging, by starting the motor 14 to rotate, the motor 14 drives the rotating shaft 15 to rotate, and the rotating shaft 15 drives the fixed sleeve 16 and the push rod 17 to rotate. When the push rod 17 rotates to the position of the abutment block 29, the abutment block 29 will be squeezed, and the abutment block 29 will slide on the slide bar 28 and compress the compression spring 31, and a gap will appear between the abutment block 29 and the bottom groove 30.

[0040] At this time, the pressure pump 6 pumps the water in the water tank 5 into the drain pipe 8, and then flows into the telescopic tube 25 through the drain pipe 8. The water will spray out from the gap between the abutment block 29 and the bottom groove 30. Then the push rod 17 continues to push the abutment block 29 and the fixed cylinder 27 to move. The fixed cylinder 27 drives the slider 23 to slide on the guide rod 22. The slider 23 moves to stretch the reset spring 26, and the telescopic tube 25 can be telescopic to adapt to the movement of the slider 23.

[0041] Until the slider 23 abuts against the end of the limit plate 19, the abutment block 29 is an elastic block, and cooperates with the arc at the bottom of the abutment block 29, so that the push rod 17 is separated from the abutment block 29 and continues to rotate, and the stretched return spring 26 drives the slider 23 to reset, so that the abutment block 29 is reset to the initial position, realizing intermittent water replenishment and the water replenishment point can be adjusted by autonomous sliding.

[0042] While the motor 14 drives the rotating shaft 15 to rotate, the rotating shaft 15 drives the sliding block 37 on the outer side of the lower part to rotate, the sliding block 37 drives the mounting sleeve 34 to rotate, and the mounting sleeve 34 drives the stirring rod 35 and the scraping rod 33 to rotate. The rotation of multiple stirring rods 35 stirs the concrete inside, and cooperates with the water replenishment on the top to reduce the solidification of the concrete. At the same time, the scraping rod 33 scrapes the inner wall of the lower warehouse body 3 to reduce the adhesion of concrete to the inner wall of the lower warehouse body 3.

[0043] When the stirring rod 35 rotates and turns to the position of the protrusion 40 on the mounting plate 1 39, the stirring rod 35 drives the scraping rod 33 and the mounting sleeve 34 to rise a certain distance due to the lifting of the protrusion 40. The auxiliary spring 38 is used to reset the mounting sleeve 34. Through the lifting cooperation of the protrusion 40 on the mounting plate 1 39 and the mounting plate 2 41, it is easy to realize the up and down movement of the stirring rod 35 and the scraping rod 33 during stirring, thereby improving the stirring effect.
