During the entire feeding process, manual pouring of raw materials into the mixing chamber is no longer required. Instead, the height of the hopper is adjusted by a feeding device and feeding wheels, and then the baffle mechanism pours the raw materials into the mixing chamber, saving time and labor throughout the process.

[0029] Please refer to Figures 1 to 7 The embodiment of the present application provides a kind of light aggregate concrete preparation and mixes device, the light aggregate concrete preparation and mixes device can include: support 1, driving device 2, driven device 10, mixing box 3, discharge mechanism 4, two guide rails 5, hopper 6, pay-off device 7, pay-off wheel 8 and baffle mechanism 9, wherein driving device 2 is fixed on support 1;Driven device 10 is arranged at the output side of driving device 2, and driven device 10 is connected with driving device 2;Mixing box 3 is fixed on support 1, and the side of mixing box 3 away from support 1 is provided with open mouth, and stirring shaft 301 is rotatably arranged in mixing box 3, one end of stirring shaft 301 is connected with driven device 10, and the outer periphery of stirring shaft 301 is provided with multiple groups of stirring blades 302;Discharge mechanism 4 is arranged at the side of mixing box 3 close to support 1;Two guide rails 5 are fixed on support 1 and extend towards the open mouth direction of mixing box 3;Hopper 6 is movably arranged on two guide rails 5, and the side of hopper 6 towards support 1 is provided with opening;Pay-off device 7 is fixed on the side of two guide rails 5 towards mixing box 3;Pay-off wheel 8 is connected with pay-off device 7 and rotationally cooperates with hopper 6;Baffle mechanism 9 is arranged at the opening of hopper 6, and baffle mechanism 9 is used to control the opening of hopper 6 to open and close.

[0030] In the embodiment, when the lightweight aggregate concrete is mixed, the wire feeding device 7 is first started, and the wire feeding wheel 8 starts to rotate under the drive of the wire feeding device 7. Then, under the action of gravity, the hopper 6 starts to move downward along the two guide rails 5. When the hopper 6 moves to the lowermost position on the two guide rails 5, the wire feeding device 7 stops feeding the wire. At this time, the raw materials to be mixed can be put into the hopper 6. After the raw materials to be mixed are put into the hopper 6, the wire feeding device 7 is started again.

It should be noted that the baffle mechanism 9 always blocks the opening at the bottom side of the hopper 6 during the downward movement or upward movement of the hopper 6, so that the raw materials to be mixed do not leak out from the bottom side of the hopper 6. When the hopper 6 containing the raw materials moves to the uppermost position of the two guide rails 5, the baffle mechanism 9 starts to act and opens the hopper 6, so that the raw materials to be mixed are poured into the mixing box 3 from the opening of the mixing box 3, to stir the raw materials to be mixed. During the whole feeding process, the raw materials are not poured into the mixing box 3 by manpower, but the height position of the hopper 6 is adjusted by the wire feeding device 7 cooperating with the wire feeding wheel 8, and the raw materials are poured into the mixing box 3 by the baffle mechanism 9, thereby saving time and effort during the whole feeding process.

[0031] In addition, after the raw materials are poured into the mixing box 3, the driving device 2 is started, thereby driving the driven device 10 to run, and further driving the stirring shaft 301 to rotate, and the plurality of stirring blades 302 also rotate, to complete the stirring of the raw materials to be mixed. After the stirring is completed, the finished products are discharged from the discharge mechanism 4 to the mixing box 3, thereby collecting the finished products.

[0033] Specifically, the movement between the hopper 6 and the two guide rails 5 is realized by adding the first roller 12, so that the hopper 6 moves more smoothly on the two guide rails 5.

[0034] Please refer to Figure 3 , Figure 4 The side of each connecting plate 11 facing the guide rail 5 is provided with a connecting piece 13, and the first connecting shaft 14 is arranged between the two connecting pieces 13.

The side of each guide rail 5 facing the hopper 6 is provided with a matching groove 16, and the second roller 15 is rotatably arranged in the corresponding matching groove 16.

[0035] Wherein, in the embodiment, the second roller 15 is additionally arranged in the matching groove 16 on the two guide rails 5, so that the hopper 6 is more stable during the movement along the two guide rails 5, and the hopper 6 is not separated from the two guide rails 5, so that the whole device is more stable during the operation.

[0037] Specifically, the second connecting shaft 19 is arranged to provide a mounting position for the pay-off reel 8, and the pay-off reel 8 only needs to rotate and reverse during the pay-off and take-up to realize the up-and-down movement of the hopper 6. Meanwhile, the third roller 20 is rotatably arranged at both ends of the second connecting shaft 19, which is conducive to the stable up-and-down movement of the hopper 6.

[0038] Please refer to Figure 3 , the pay-off device 7 can include a fixed frame 701, a pay-off motor 702, and a wire reel 703, wherein the fixed frame 701 is fixed to the side of the two guide rails 5 facing the mixing box 3, and the fixed frame 701 is located on the open side of the mixing box 3; the pay-off motor 702 is fixed to the side of the fixed frame 701 away from the mixing box 3; the wire reel 703 is fixed to the output shaft end of the pay-off motor 702, and the wire reel 703 and the pay-off reel 8 are wound together by the same wire cable.

[0039] In the embodiment, when the pay-off is performed, the pay-off motor 702 is started to drive the wire reel 703 to rotate, and the wire reel 703 and the pay-off reel 8 are wound together by the wire cable, so that the wire reel 703 rotates to drive the pay-off reel 8 to rotate, thereby realizing the up-and-down movement of the hopper 6. In the embodiment, the wire reel 703 and the pay-off reel 8 are connected by the wire cable, and the transmission is reliable when the hopper 6 is driven to move.

[0040] Please refer to Figure 2 , the driving device 2 can include a driving motor 201 and a speed reducer 202, wherein the driving motor 201 is fixed to the support 1; the speed reducer 202 is fixed to the support 1, and the output end of the driving motor 201 is connected to the input end of the speed reducer 202 by a belt; wherein the output end of the speed reducer 202 is connected to the stirring shaft 301.

[0041] When the raw materials in the mixing box 3 need to be stirred, the driving motor 201 is first started, and under the driving of the driving motor 201, the speed reducer 202 starts to operate, and then the speed reducer 202 slows down the rotating speed of the driving motor 201 and then transmits power to the stirring shaft 301, and the uniform mixing of the raw materials is realized under the stirring of the stirring shaft 301. It should be noted that the structure of the speed reducer 202 is a prior art, and will not be described here.

[0045] Specifically, the base 304 is perpendicular to the axis of the stirring shaft 301, and the angle between the blade portion 305 and the axial direction of the stirring shaft 301 means that the blade portion 305 is not parallel to the axis of the stirring shaft 301, and at the same time, in order to ensure the stirring effect, the blade portion 305 is also not perpendicular to the axis of the stirring shaft 301. That is, the angle between the blade portion 305 and the axial direction of the stirring shaft 301 is between 0° and 90°, so that the inclined arrangement of the blade portion 305 can make the raw materials be stirred and mixed more uniformly.

[0047] When the raw materials in the mixing box 3 are stirred and mixed uniformly, the finished product needs to be discharged from the discharge port of the mixing box 3.

[0048] When the raw materials in the mixing box 3 are stirred, the discharging motor 401 drives the baffle 402 to completely block the discharging port, so that the raw materials in the mixing box 3 will not leak; when the stirring is completed, the discharging motor 401 drives the baffle 402 to rotate by a certain angle (which can be 90°), so that the discharging port is opened, and the finished product after stirring is discharged from the discharging port, which is convenient for collecting the finished product.

[0049] Please refer to Figure 5 The baffle mechanism 9 can include a rotating motor 901, a rotating rod 902, and a blocking baffle 903, wherein the rotating motor 901 is fixed to one side of one of the two connecting plates 11 away from the hopper 6; the rotating rod 902 penetrates through the two connecting plates 11 and is in rotating cooperation with the two connecting plates 11; and the blocking baffle 903 is fixed to the end side of the rotating rod 902 and can completely block the opening of the hopper 6.

[0050] In this embodiment, the baffle mechanism 9 is further refined. When the hopper 6 transports the raw materials, the blocking baffle 903 is attached to the opening of the hopper 6 under the action of the rotating motor 901, so that the raw materials will not flow out of the opening of the hopper 6; when the hopper 6 transports the raw materials to the top end, the rotating motor 901 drives the blocking baffle 903 to rotate and opens the opening of the hopper 6, so that the raw materials can fall into the mixing box 3 from the opening of the hopper 6 to stir the raw materials.
