Description

Technical Field

[0001] The invention relates to the technical field of building construction, in particular to a mixing and preparing device for building mortar. Background Art

[0002] In the field of construction engineering, mortar mixing is a crucial basic process. Construction mortar is mainly made of lime, fine sand, cement, and water. Its mixing effect is directly related to the quality of building materials and the smoothness of subsequent construction. Traditional mortar mixing devices usually use a single mechanical drive method to control the movement of the mixing blades to achieve mixing of the mortar.

[0003] In terms of mixing effect, the angle of traditional stirring blades is fixed or can only be adjusted mechanically according to the preset program, and it is difficult to perform adaptive optimization according to the real-time status of the mortar mixing process. Since the mortar at different stages of mixing has different requirements for mixing intensity and method, such as the powdered lime, fine sand, and cement added to the bottom of the mixing bin at the initial stage of mixing, if the stirring blade angle is large, it is easy for the stirring blade to be damaged during mixing. In the middle and late stages of mixing, the consistency, uniformity and other characteristics of the mortar change. At this time, it is necessary to finely adjust the stirring blade angle to further improve the mixing uniformity and avoid mixing dead corners. In addition, due to the presence of lime components in the mixture, heat will be released when it meets water. If the heat cannot be reasonably discharged, it will affect the mixing and forming effect of the mortar. However, the traditional mixing method cannot flexibly meet these dynamic requirements, resulting in uneven distribution of components, local agglomeration and other quality problems in the mortar after mixing, which seriously affects the performance of building materials and poses a potential threat to the quality and durability of construction projects.

[0017] The present invention enables the stirring blades to be in a horizontal state during the initial stirring, and less damage is caused to the stirring blades during stirring. The lime in the mixture generates heat when it meets water, and the generated heat is conducted to the heat conduction pipe, which causes the gas inside the stirring blades to be heated and expand.

The middle part of gear 2 1029 is fixedly connected to one end of the stirring rod 1016 close to the rotating shaft 102. The middle part of the limiting plate 1027 is fixedly connected with a piston rod 1030, the middle part of the piston rod 1030 is fixedly connected to the outer periphery of the middle part, and the lower end of the limiting ring 1036 is fixedly connected to the outer periphery of the spring 2 1037.

[0034] Preferably, the outer periphery of the limiting ring 1036 is slidably connected to the inner upper part of the limiting cavity 108 , the lower end of the second spring 1037 is fixedly connected to the inner bottom wall of the limiting cavity 108 , and the outer periphery of the piston rod 1030 is slidably connected to the inside of the rotating shaft 102 .

[0035] Preferably, a piston cavity 107 is opened at the upper end of the rotating shaft 102, and a heat conduction pipe 1023 is arranged in the inner middle and lower part of the mixing bin 101.

The right end of the exhaust pipe 1025 is connected to a pressure relief valve 1026, and fixing rods 1034 are evenly distributed on the upper end of the heat conduction pipe 1023.

[0036] Preferably, the lower end of the pressure relief valve 1026 is fixedly connected to the right side of the middle of the upper end of the mixing bin 101, the outer periphery of the lower end of the connecting pipe 1024 is fixedly connected to the middle opening of the rear side of the mixing bin 101, and the end of the fixing rod 1034 away from the heat transfer pipe 1023 is fixedly connected to the middle of the inner wall of the mixing bin 101.

[0037] Specifically, when it is necessary to stir the building mortar, the lime, fine sand and cement mixture mixed in a certain proportion is added into the mixing bin 101 through the loading port 2, and an appropriate amount of clean water is added through the loading port 2, and the reduction motor 106 is started, and the large pulley 103 is driven to rotate through the small pulley 105 and the transmission belt 104, and then all the stirring rods 1016, the stirring drum 1018 and the stirring blades 1020 are driven to rotate through the rotating shaft 102 to stir and mix the mixture and the clean water. During the initial stirring, the stirring blades 1020 are in a horizontal state, and the damage to the stirring blades 1020 during stirring is small. Since the lime in the mixture generates heat when it meets water, the generated heat is conducted to the heat pipe 1023, which causes the gas inside the stirring blades 1020 to be heated and generate The expanded gas is conducted to the interior of the piston chamber 107 through the connecting tube 1024, and squeezes the piston rod 1030 downward through the piston plate 1035, thereby squeezing the limit plate 1027 downward, and then driving all the racks 1028 downward. At this time, all the stirring rods 1016 are driven to rotate through the gear 2 1029, and then all the stirring blades 1020 are driven to adjust their angles through the stirring drum 1018, so that the stirring blades 1020 are in a horizontal state at the initial stage of stirring, and the damage to the stirring blades 1020 is relatively small. In the later stage of stirring, the angle of the stirring blades 1020 is large, and compared with the traditional mechanical adjustment method, the stirring blades 1020 can be automatically and flexibly adjusted in timing and angle according to the heat release of the reaction between the mixture and water, which can further improve the stirring effect.

[0038] Preferably, the interior of the piston chamber 107 is slidably connected to a piston plate 1035, the upper end of the piston plate 1035 is fixedly connected to a ratchet 1031, the front side of the ratchet 1031 is meshingly connected to a pawl 1039, the front end of the pawl 1039 is fixedly connected to a pull rod 1032, and a spring 1033 is provided on the middle periphery of the pull rod 1032.

[0039] Preferably, the lower end of the piston plate 1035 is fixedly connected to the upper end of the piston rod 1030 , and the rear end of the spring 1033 is fixedly connected to the upper front end of the rotating shaft 102 .

[0040] Specifically, when the piston plate 1035 descends inside the piston chamber 107, the piston plate 1035 drives the ratchet 1031 to descend, and then the ratchet 1039 cooperates with the spring 1033 on the periphery of the pull rod 1032 to lock the position of the piston plate 1035 inside the piston chamber 107, so as to avoid the resistance generated by the stirring blades 1020 when stirring the mortar, which causes the stirring blades 1020 to reset after the mortar releases heat, so as to ensure the subsequent stirring effect after the heat release of the mixed material. After the stirring is completed, the discharge valve 4 is opened to release the mortar, and the pull rod 1032 is pulled, and the spring 2 1037 and the limit ring 1036 in the limit chamber 108 cooperate to drive the piston rod 1030 to reset, and then drive all the stirring blades 1020 to reset, so as to facilitate the stirring of the newly added mixed material and water, and complete the above-mentioned stirring cycle.

[0041] Preferably, a toothed disc 109 is fixedly connected to the outer periphery of the middle and upper part of the rotating shaft 102, and the front and rear sides of the lower end of the toothed disc 109 are meshedly connected to a gear 1010, the middle of the gear 1010 is fixedly connected to a limiting shaft 1011, and the lower end of the limiting shaft 1011 is meshedly connected to the front and rear sides of the upper end of the toothed disc 2 1012, and the lower end of the toothed disc 2 1012 is fixedly connected to a slide plate 1013, and sliding balls 1014 are evenly distributed inside the slide plate 1013, and the lower ends of the sliding balls 1014 are fixedly connected to connecting rods 1015.

[0042] Preferably, the middle parts of gear plate 2 1012 and slide plate 1013 are both rotatably connected to the middle periphery of rotating shaft 102, and the end of limiting shaft 1011 away from gear 1 1010 is rotatably connected to the upper ends of the inner front and rear sides of mixing bin 101.

[0043] Specifically, when the rotating shaft 102 drives all the stirring blades 1020 to rotate, the gear 1010 is driven to rotate through the toothed disc 109, and then the slide plate 1013 is driven to rotate in the opposite direction to the rotating shaft 102 through the toothed disc 1012. At this time, due to the special shape of the slide plate 1013, the sliding ball 1014 and the connecting rod 1015 can cooperate with the connecting groove 1021 at the upper end of the stirring drum 1018 to drive the stirring drum 1018 to slide back and forth on the upper end of the stirring rod 1016, so as to stir different positions of the mixed materials in the mixing bin 101, accelerate the mixing speed of the mixed materials and water, and the upper end of the stirring drum 1018 The scraping blade 1022 slides back and forth, and cooperates with the rotation of the slide plate 1013 to wipe the inner and outer peripheries of the heat pipe 1023 at multiple points, remove the slurry that has completed heat exchange, and allow the new slurry to contact the heat pipe 1023 to complete the heat exchange, so that the heat can be controlled and discharged when the mixture reacts with water during stirring, thereby improving the stirring and molding effect of the slurry. When the air pressure inside the piston chamber 107 reaches the optimal stirring angle for adjusting the stirring blade 1020, the pressure is relieved through the exhaust pipe 1025 and the pressure relief valve 1026, so that the hot gas can be discharged, thereby preventing the heat pipe 1023 from being deformed due to the expanding gas.

[0044] Working principle: When it is necessary to stir the building mortar, the lime, fine sand and cement mixture mixed in a certain proportion is added into the mixing bin 101 through the loading port 2, and an appropriate amount of clean water is added through the loading port 2, and the reduction motor 106 is started, and the large pulley 103 is driven to rotate through the small pulley 105 and the transmission belt 104, and then all the stirring rods 1016, the stirring drum 1018 and the stirring blades 1020 are driven to rotate through the rotating shaft 102 to stir and mix the mixture and the clean water. During the initial stirring, the stirring blades 1020 are in a horizontal state, and the damage to the stirring blades 1020 during stirring is small. Since the lime in the mixture will generate heat when it meets water, the generated heat is conducted to the heat pipe 1023, which will cause the stirring blades 1020 to be heated. The gas in the inner part expands due to the heat, and the expanded gas is conducted to the inside of the piston chamber 107 through the connecting pipe 1024, and squeezes the piston rod 1030 downward through the piston plate 1035, thereby squeezing the limit plate 1027 downward, and then driving all the racks 1028 to move downward. At this time, all the stirring rods 1016 are driven to rotate through the gear 2 1029, and then all the stirring blades 1020 are driven to adjust their angles through the stirring barrel 1018, so that the stirring blades 1020 are in a horizontal state at the initial stage of stirring, causing less damage to the stirring blades 1020, and the angle of the stirring blades 1020 is large in the later stage of stirring, and compared with the traditional mechanical adjustment method, the timing of the stirring blades 1020 can be automatically and flexibly adjusted according to the heat release of the reaction between the mixed material and water. The stirring effect can be further improved by adjusting the angle of the stirring rod 1016. When the rotating shaft 102 drives all the stirring blades 1020 to rotate, the gear 1010 is driven to rotate through the toothed disc 109, and then the slide plate 1013 is driven to rotate in the opposite direction to the rotating shaft 102 through the toothed disc 1012. At this time, due to the special shape of the slide plate 1013, the sliding ball 1014 and the connecting rod 1015 can cooperate with the connecting groove 1021 at the upper end of the stirring drum 1018 to drive the stirring drum 1018 to slide back and forth on the upper end of the stirring rod 1016, so as to stir different positions of the mixed materials inside the mixing bin 101 and accelerate the mixing speed of the mixed materials and water. In addition, the scraping blade 1022 at the upper end of the stirring drum 1018 slides back and forth, and cooperates with the rotation of the slide plate 1013 to conduct heat conduction. The inner and outer peripheries of the tube 1023 are wiped at multiple points to remove the mortar that has completed the heat exchange, so that the new mortar contacts the heat-conducting tube 1023 to complete the heat exchange, so that the heat can be controlled and discharged when the mixture reacts with water during stirring, thereby improving the stirring and molding effect of the mortar, and when the air pressure inside the piston chamber 107 reaches the optimal stirring angle of the stirring blade 1020, the pressure is released through the exhaust pipe 1025 and the pressure relief valve 1026, so that the hot gas can be discharged, and the deformation of the heat-conducting tube 1023 caused by the expanding gas can be avoided. When the piston plate 1035 descends inside the piston chamber 107, the ratchet 1031 is driven to descend through the piston plate 1035, and then the ratchet 1039 cooperates with the spring 1033 on the outer periphery of the pull rod 1032.The piston plate 1035 is locked in the position inside the piston chamber 107 to prevent the stirring blades 1020 from resetting after the mortar heat release is completed due to the resistance generated by the stirring blades 1020 when stirring the mortar, so as to ensure the subsequent stirring effect after the mixed material heat release is completed. After the stirring is completed, the discharge valve 4 is opened to release the mortar, and the pull rod 1032 is pulled. The spring 1037 and the limit ring 1036 in the limit chamber 108 cooperate to drive the piston rod 1030 to reset, and then drive all the stirring blades 1020 to reset, so as to facilitate the stirring of the newly added mixed material and water, and complete the above-mentioned stirring cycle.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
