DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The utility model provides a technical solution: a foam lightweight soil feeding device, including a base 1, a mixing box 2 and a foam storage box 4, a mixing box 2 is installed in the middle of the top of the base 1, and the top plate 3 is connected to the top of the base 1 through columns on both sides, the top of the top plate 3 is connected to the foam storage box 4 on one side, and the top of the top plate 3 is connected to the cement slurry storage box 5 on the other side, the bottom of the foam storage box 4 is connected to the outlet pipe 6, the bottom of the outer wall of the mixing box 2 is connected to the outlet pipe 7, the outer wall of the outlet pipe 6 is provided with a filter mechanism 8, and the filter mechanism 8 includes a stepping motor 81, a guide gear 82, a rack 83, a slide rail 84, an extension plate 85, a filter screen 86, a guide rod 87, a support column 88 and a spring 89, the top plate 3 A stepper motor 81 is connected through an installation box, and a guide gear 82 is connected to the output end of the stepper motor 81; a rack 83 is meshedly connected to the outer wall of the guide gear 82, and a slide rail 84 is slidably connected to the outer wall of the rack 83; an extension plate 85 is connected to the bottom end of the rack 83, and a filter screen 86 is welded to the outer wall of the extension plate 85; guide rods 87 are slidably connected to the inside of the filter screen 86 on both sides, and a support column 88 is connected to the top of the guide rod 87; a spring 89 is sleeved on the outer wall of the guide rod 87, and an elastic telescopic mechanism is formed between the guide rod 87, the spring 89 and the filter screen 86; the slide rail 84 is fixedly connected to the top plate 3, the top of the guide rod 87 is welded to the support column 88, and the top of the support column 88 is welded to the top plate 3.

[0027] In specific implementation, during the use of the foam lightweight soil, when the feeding device is used to assist, in order to prevent impurities in the foam from mixing with the cement slurry, when the foam needs to be filtered, because the filter net 86 is located below the outlet pipe 6, when the outlet pipe 6 outputs the foam, the foam is filtered through the filter net 86, and then the impurities in the foam are filtered to prevent the impurities in the foam from affecting the quality of the foam lightweight soil;

[0028] As the use time increases, when the filter 86 is clogged and needs to be cleaned, the stepper motor 81 is started first. Since the output end of the stepper motor 81 is connected to the guide gear 82, the stepper motor 81 starts to drive the guide gear 82 to rotate. Since the guide gear 82 is meshed with the rack 83, the guide gear 82 rotates to make the rack 83 rotate along the slide rail 84. Then the rack 83 moves downward to drive the extension plate 85 to move downward together. Since the extension plate 85 is connected to the filter 86, the extension plate 85 moves to make the filter 86 move downward along the guide rod 87.

[0029] When the filter screen 86 moves, it squeezes the spring 89, causing the spring 89 to deform. Then, as the guide gear 82 rotates, the toothed side of the guide gear 82 is disconnected from the rack 83, and the squeezing of the extension plate 85 is cancelled. At this time, the spring 89 resets and drives the filter screen 86 to move upward, causing the filter screen 86 to collide with the support column 88. Then, as the guide gear 82 rotates, the filter screen 86 repeatedly collides with the support column 88, and automatically shakes off the impurities that cause the filter screen 86 to be blocked, preventing the filter screen 86 from being blocked and affecting the filtering effect of the foam, thereby facilitating filtering and preventing clogging when the foam lightweight soil feeding device is used.

[0030] See also Figure 1 , Figure 2 , Figure 6 and Figure 7 It can be seen that an auxiliary mechanism 9 is provided on the outer wall of the base 1, and the auxiliary mechanism 9 includes a protective box 91, a driving motor 92, a stirring rod A93, a gear A94, a gear B95 and a stirring rod B96, and a protective box 91 is docked on the side of the outer wall of the mixing box 2 away from the discharge pipe 7; the outer wall of the protective box 91 is connected to the driving motor 92, and the stirring rod A93 is docked at the output end of the driving motor 92, and the outer wall of the stirring rod A93 close to the driving motor 92 is sleeved with a gear A94; the outer wall of the gear A94 is meshingly connected with the gear B95, and the stirring rod B96 is docked inside the gear B95; the stirring rod A93 and the stirring rod B96 are parallel to each other, and the stirring rod A93 and the stirring rod B96 are connected to the mixing box 2 through a bearing seat on the side away from the driving motor 92, and the bottom end of the driving motor 92 is connected to the base 1 through a support platform.

[0031] In specific implementation, when the foamed lightweight soil is used and assisted by the feeding device, in order to increase the production speed of the foamed lightweight soil, when it is necessary to increase the mixing efficiency of the mixing box 2, the driving motor 92 on the protective box 91 is first started. Since the output end of the driving motor 92 is connected to the stirring rod A93, the driving motor 92 rotates forward to drive the stirring rod A93 to rotate forward, and since the stirring rod A93 is connected to the gear A94, the stirring rod A93 rotates and drives the gear A94 to rotate together;

[0032] Because gear A94 and gear B95 are meshingly connected, gear A94 rotates forward to drive gear B95 to reverse, and then gear B95 reverses to drive stirring rod B96 to reverse. At this time, stirring rod A93 and stirring rod B96 form relative rotation, thereby increasing the mixing speed of foam and cement slurry, and then mixing is not only carried out by a single stirring rod, thereby reducing mixing time and improving work efficiency, so that when the feeding device of foam lightweight soil is used, it plays a role in facilitating the improvement of work efficiency.

[0033] To sum up, when the feeding device of the foam lightweight soil is used, the foam storage box 4 is first allowed to discharge the foam through the discharge pipe 6, and then the cement slurry storage box 5 on the top plate 3 is allowed to discharge the cement slurry. At this time, the cement slurry and the foam both enter the mixing box 2 on the base 1, and then are stirred and mixed by the mixing box 2, and then the foam lightweight soil is discharged and fed through the discharge pipe 7. This is the prior art and will not be elaborated on here. The impurities in the foam are filtered through the filtering mechanism 8 to prevent the impurities in the foam from affecting the quality of the foam lightweight soil, and the filter screen 86 is repeatedly collided with the support column 88, thereby automatically shaking off the impurities that cause the filter screen 86 to be blocked, and preventing the filter screen 86 from being blocked and affecting the filtering effect of the foam. The mixing speed of the foam and cement slurry is improved by the auxiliary mechanism 9, and it is not just mixed by a separate stirring rod, thereby reducing the stirring time and improving the work efficiency. The content not described in detail in this description belongs to the prior art known to professional and technical personnel in this field.
