It should be noted that, the discharge end of the feeding hopper 6 may be rotatably disposed in the feeding chute 14 through a bearing, so that the stirring drum 2 may not drive the feeding hopper 6 to rotate when rotating.
The stirring device comprises a stirring cylinder 2, a filter cylinder 3, a plurality of first fixed partition plates 10, a plurality of second fixed partition plates 12, a first mud scraping mechanism and a limiting mechanism, wherein the fixed partition plates are fixedly arranged on the inner wall of the stirring cylinder 2 at equal intervals, the first mud scraping mechanism is used for scraping mortar on the inner wall of the stirring cylinder 2, the first mud scraping mechanism comprises a plurality of arc-shaped guide rails 9, and a plurality of movable partition plates 11 and a plurality of reset springs 13. Specifically, the number of the arc-shaped guide rails 9 is two, and the arc-shaped guide rails 9 are arranged in parallel, so that the movable partition plate 11 can slide along the arc-shaped guide rails 9 without tilting.
The arc-shaped guide rail 9 is fixedly arranged between the first fixed partition plate 10 and the second fixed partition plate 12, the arc-shaped guide rail 9 penetrates through the movable partition plate 11 in a sliding mode, and the movable partition plate 11 is elastically connected to the adjacent second fixed partition plate 12 through the reset spring 13. As shown in fig. 2, the gap between the adjacent first fixed partition plate 10 and second fixed partition plate 12 is small, and the movable partition plate 11 is attached to the second fixed partition plate 12 by the initial state of the return spring 13, so that cement mortar will be located between the first fixed partition plate 10 and the movable partition plate 11 below when flowing into the bottom of the mixing drum 2 from the feed hopper 6, the feed chute 14 and the shunt chute 15.

Further, by designing the number of teeth of the half gear 18 and the rack 19, and parameters such as the diameter of the half gear 18, it is ensured that the baffle 22 just starts to extend outwards when the movable partition 11 rotates to approach the baffle 22, and the baffle 22 is located between the second fixed partition 12 and the movable partition 11, so that the movable partition 11 can be limited.
The filter cylinder 3 is internally provided with a second mud scraping mechanism which is used for scraping mortar on the inner wall of the filter cylinder 3, the second mud scraping mechanism comprises a scraping plate 23, a sliding plug cylinder 24, a sliding plug 25, a push rod 26 and two telescopic air bags 21, the sliding plug 25 is arranged in the sliding plug cylinder 24 in a sealing sliding manner, the scraping plate 23 is arranged in the filter cylinder 3 in a sliding manner, the push rod 26 fixedly connects the sliding plug 25 with the scraping plate 23, the telescopic air bags 21 fixedly connect the connecting plate 20 with the inner wall of the mechanism groove 171 together, and the telescopic air bags 21 are communicated with the inner part of the sliding plug cylinder 24 through air pipes, so that air discharged by the telescopic air bags 21 can smoothly enter the sliding plug cylinder 24, and the sliding plug 25 is pushed to move.

The driving mechanism can push the stirring cylinder 2 to rotate anticlockwise circularly under the action of the driving motor 4, the gear 8 and the outer toothed ring 5, and the filtering cylinder 3 is rotationally arranged in the stirring cylinder 2, so that the filtering cylinder 3 is not driven to rotate when the stirring cylinder 2 rotates, the stirring cylinder 2 can drive the half gear 18 coaxially arranged with the stirring cylinder to rotate circularly, the half gear 18 is meshed with the two racks 19, the two racks 19 and the connecting plate 20 are pushed to perform periodic reciprocating movement, and the baffle 22 can be continuously extended and retracted from the mechanism groove 171.
When the baffle 22 stretches out to limit the movable partition 11, the stirring cylinder 2 still continuously drives the first fixed partition 10, the second fixed partition and the arc-shaped guide rail 9 to rotate, so that the distance between the movable partition 11 and the first fixed partition 10 below is smaller and smaller, the movable partition 11 can continuously scrape mortar in a wide area into the filter cylinder 3, and compared with the falling mode of relying on dead weight in the background art, in the embodiment, part of the lifted mortar can be scraped into the filter cylinder 3, so that the penetrating force of the concrete passing through the filter cylinder 3 is improved, meanwhile, the mortar passes through the filter cylinder 3 in batches, and a large piece of concrete cannot directly fall above the filter cylinder 3 to prevent the mortar from passing through the filter cylinder 3, so that the stirring effect is improved, and the stirring efficiency is also improved.

Therefore, the periodically telescopic baffle 22 can continuously push each movable baffle 11, and the return spring 13 can continuously pull each movable baffle 11 to move back and forth for resetting, so that each movable baffle 11 continuously reciprocates between the first fixed baffle 10 and the second fixed baffle 12, and mortar remained on the inner wall of the stirring cylinder 2 can be scraped off continuously, thereby facilitating the subsequent cleaning work of the stirring cylinder 2.
Further, the rack 19 and the connecting plate 20 assembly which move back and forth continuously squeeze the telescopic air bags 21 on two sides of the rack, so that air in the telescopic air bags 21 is continuously blown into the sliding plug cylinder 24 or is drawn back from the sliding plug cylinder 24, the sliding plug 25 moves back and forth in the sliding plug cylinder 24, the push rod 26 and the scraping plate 23 can be pushed to move back and forth in the filter cylinder 3, mortar remained on the inner wall of the filter cylinder 3 can be scraped continuously, on one hand, the mortar can be prevented from being remained on the inner wall of the filter cylinder 3 and being condensed, so that cleaning is difficult, and on the other hand, mortar at the inner bottom of the filter cylinder 3 can be promoted to flow back from the filter cylinder 3 to the inner bottom of the stirring cylinder 2, so that the circulation mixing work efficiency of the stirring cylinder 2 is improved, and the mixing efficiency of the mortar is improved.
Embodiment two:
referring to fig. 6-7, unlike the first embodiment, the scraping plate 23 is provided with a vibrating mechanism for vibrating the inner wall of the filter cylinder 3, and the vibrating mechanism includes a vibrating plate 28, a conductive spring 29 and a spiral coil 27, and specifically, an insulating rubber layer with good wear resistance is arranged outside the conductive spring 29, so as to prevent the conductive spring 29 from being shorted by cement mortar.
Wherein the sliding plug 25 is made of magnetic materials, the vibrating plate 28 is rotatably arranged on the side wall of the scraping plate 23, the spiral coil 27 is embedded in the inner wall of the sliding plug cylinder 24, and the conductive spring 29 is electrically connected with the spiral coil 27. It should be noted that, the spiral coil 27 is only disposed on a portion of the side wall of the plunger 24 near the scraper 23, so that when the plunger 25 moves back and forth in the plunger 24, the spiral coil 27 can be completely moved in and out to generate an induced current, and on the other hand, the magnetic flux of the spiral coil 27 can be zero for a certain period of time and no induced current is generated, so that the conductive spring 29 can be intermittently supplied with power.
In this embodiment, when the magnetic sliding plug 25 slides back and forth in the sliding plug barrel 24, the sliding plug barrel 27 is continuously moved in and out of the spiral coil 27 and forces the spiral coil 27 to generate magnetic flux change, so that induced current can be intermittently generated, when the sliding plug 25 is completely moved out of the spiral coil 27, the magnetic flux in the spiral coil 27 is zero, no induced current exists at this time, the conductive spring 29 can be electrified and contracted each time the induced current is generated by the spiral coil 27, so that the vibrating plate 28 is pulled to rotate towards the center of the scraping plate 23, and after the induced current is lost, the conductive spring 29 can push the vibrating plate 28 to rotate and reset, and therefore the vibrating plate 28 can rotate back and forth and continuously strike the inner wall of the filter cylinder 3, and along with the movement of the scraping plate 23, the vibrating plate 28 can strike the whole inner wall part of the filter cylinder 3 so as to promote the mortar in the meshes of the filter cylinder 3 to fall off, and the mortar is prevented from being condensed in the meshes to cause blockage.
The foregoing is only a preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art, who is within the scope of the present invention, should make equivalent substitutions or modifications according to the technical scheme of the present invention and the inventive concept thereof, and should be covered by the scope of the present invention.
