[0027] A plurality of control components for controlling the feed ratio are arranged below the feed table 101, and each control component is arranged one-to-one with each feed tube 102. The control components include a feed frame 201, and a sliding component for assisting the feed frame 201 in sliding and guiding is arranged between the feed frame 201 and the lower end of the feed table 101. A partition 202 is arranged inside the feed frame 201, and the feed frame 201 forms a material storage cavity for storing materials under the dividing action of the partition 202. A blocking plate 203 for blocking the feed tube 102 after the feed frame 201 slides is fixed to the upper end of the partition 202. An adjusting component for adjusting the position of the blocking plate 203 is arranged on the feed frame 201, and a blocking component for blocking after storing materials is arranged below the blocking plate 203. A transmission component for transmitting each group of feed frames 201 is arranged on the feed table 101;

[0028] During the processing of self-compacting concrete, the feeding and conveying operations of each group of self-compacting concrete raw materials are completed through the mutual cooperation of the control components, the adjustment components and the transmission components. During the entire feeding process, the feeding amount of each group of self-compacting concrete raw materials is consistent with the volume of the storage cavity of each group of feeding frames 201, so that the mixing proportioning and feeding operations are carried out according to the specified ratio. In addition, during the entire mixing proportioning process, the operation is simple and the implementation is convenient.

The blocking circular plate 401 is fixed to the lower end of the feeding platform 101 through multiple groups of connecting rods. A material drop hole 402 for dropping materials after feeding proportioning is centrally arranged on the blocking circular plate 401. The feeding frames 201 on each group of control components are pushed to move away from each other under the feeding platform 101. During the movement, the material storage cavities inside each group of feeding frames 201 are respectively communicated with each group of feeding pipes 102, and the bottom of the moving feeding frame 201 is abutted against and blocked by the blocking circular plate 401, which is convenient for material storage operation.

[0030] The transmission assembly includes a first threaded sleeve 501, a connecting plate 502 is arranged between the first threaded sleeve 501 and one side of the feeding frame 201, and the two ends of the connecting plate 502 are rotatably connected to the outer sides of the first threaded sleeve 501 and the feeding frame 201, respectively. A lifting assembly for lifting the first threaded sleeve 501 is arranged on the feeding platform 101; the lifting assembly includes a U-shaped frame 601 fixed to the upper end of the feeding platform 101, and a first threaded rod 602 is rotatably connected to the U-shaped frame 601, and the first threaded rod 602 and the first threaded sleeve 501 are meshed with each other.

During the rotation of the first threaded rod 602, the first threaded sleeve 501 is driven to move up and down through the mutual meshing transmission between the first threaded rod 602 and the first threaded sleeve 501. During the lifting and lowering movement of the first threaded sleeve 501, the connection transmission action of each group of connecting plates 502 drives each group of feeding frames 201 to move closer to or away from each other.

[0031] The sliding assembly includes two groups of mounting frames 301 fixed at the lower end of the feed table 101, and the two groups of mounting frames 301 are symmetrically arranged on both sides of the feed frame 201. A mounting rod 302 is fixed on the mounting frame 301, and a connecting block 303 is slidably connected to the mounting rod 302. The connecting block 303 is fixed to the outer side of the feed frame 201; through the mounting frame 301, the mounting rod 302 and the connecting block 303, the sliding guide movement of the auxiliary feed frame 201 after being subjected to force is facilitated.

[0032] The adjusting component includes a transmission plate 701 fixed on the blocking plate 203, a second threaded sleeve 702 is fixed on the transmission plate 701, a second threaded rod 703 is threadedly connected to the second threaded sleeve 702, one end of the second threaded rod 703 is rotatably connected to the outer side of the feeding frame 201, and a driving pin 704 is fixed to the other end of the second threaded rod 703.

The movement of the partition 202 adjusts the volume of the material storage chamber, which is convenient for adjusting the proportion of the ratio. During the adjustment process, the adjusting component drives the second threaded rod 703 to rotate through the driving pin 704. During the rotation of the second threaded rod 703, the mutual engagement transmission between the second threaded rod 703 and the second threaded sleeve 702 causes the transmission plate 701 to move. During the movement of the transmission plate 701, the sliding guiding effect of each group of T-bars 705 causes the transmission plate 701, the sealing plate 203 and the partition 202 to move after being subjected to force.

[0034] After each group of feeding frames 201 is driven to the designated position, each group of self-compacting concrete raw materials to be transported is transported through each group of feeding pipes 102. During the transportation process, each group of self-compacting concrete raw materials fills the storage cavity of the feeding frames 201 on each group of control components. After the filling is completed, the lifting component and the transmission component are used to drive each group of feeding frames 201 to move closer to each other. With the movement of the feeding frames 201, the blocking circular plate 401 no longer blocks the bottom of the feeding frames 201. At this time, the feeding frames 201 are filled with The filled self-compacting concrete raw materials are transported outwards through the drop holes 402 to the designated positions for subsequent processing, completing the feeding and conveying operation of each group of self-compacting concrete raw materials. During the entire feeding process, the feeding amount of each group of self-compacting concrete raw materials is respectively consistent with the volume of the storage cavity of each group of feeding frames 201, realizing the mixing proportion feeding operation according to the designated ratio. In addition, during the entire proportioning process, the operation is simple and convenient to implement, and there is no need to use weighing equipment for repeated auxiliary weighing, which is convenient for the efficient proportioning feeding operation of the self-compacting concrete raw materials.

[0035] While driving the groups of feeding frames 201 to move toward each other, the bottoms of the groups of feeding pipes 102 are blocked by the blocking plates 203 to prevent leakage of materials from occurring in the feeding pipes 102 during the feeding and conveying process.
