It should be understood that the structures of the motor, the stirring rod, and the like, which are also provided on the storage vat 1, and the structures of the motor, the stirring rod, the helical blade, and the like, which are provided on the helical conveying device 2, are conventional existing structures, and therefore, even if detailed description is omitted, understanding of the scheme of the present application by a person skilled in the art is not affected.

In order to achieve the purpose of precisely adjusting the opening degree of the discharging member 3, a plurality of second positioning grooves 125 are continuously formed in the first baffle 31, so that after the second push rod 121 rotates, the first baffle 31 can be provided with the second positioning grooves 125 matched with the third positioning members 124; after the third positioning member 124, the second positioning slot 125 and the limit spring 126 are arranged, so that the opening degree of the discharging member 3 is adjusted to be proper by rotating the second push rod 121, the relative positions of the first driving gear 111 and the first baffle 31 are fixed through the matching of the third positioning member 124 and the second positioning slot 125, the first driving gear 111 can not rotate any more, that is, the second driving gear 112 and the third driving gear 113 meshed with the first driving gear 111 can not rotate, the positions of the first driving rod 114, the second driving rod 115, the third driving rod 116 and the fourth driving rod 117 are fixed, the positions of the third baffle 33 and the fourth baffle 34 are limited through the fixing of the positions of the second driving rod 115 and the fourth driving rod 117, and therefore, when concrete raw materials pass through the discharging member 3, the third baffle 33 and the fourth baffle 34 are prevented from being impacted, and the third baffle 33 and the fourth baffle 34 are rotated, the opening degree of the discharging part 3 is increased, so that the concrete is splashed outwards.

Set up third locating lever 13 and fourth locating lever 14 for when needing to promote second push rod 121, through the mutual conflict of fourth locating lever 14 and second locating lever 127, ensure the separation of third locating lever 124 and second constant head tank 125, avoid needing outwards to stimulate second locating lever 127 always in the in-process that promotes second push rod 121, thereby make the regulation operation of the opening degree of play work piece 3 simple more convenient.

The second driving rod 115 and the fourth driving rod 117 respectively push the third shutter 33 and the fourth shutter 34 through the first connecting plate 15 and the second connecting plate 16, compared with the case that the third shutter 33 and the fourth shutter 34 are directly pushed through the second driving rod 115 and the fourth driving rod 117, the contact area between the third shutter 33 and the fourth shutter 34 is increased, so that the process of pushing the third shutter 33 and the fourth shutter 34 through the second driving rod 115 and the fourth driving rod 117 is more stable, meanwhile, the first connecting plate 15 and the third shutter 33 are made of magnetic materials which are mutually attracted, the second connecting plate 16 and the fourth shutter 34 are made of magnetic materials which are mutually attracted, and the connection stability between the first connecting plate and the fourth shutter is increased.

When the second driving rod 115 and the fourth driving rod 117 respectively push the third baffle plate 33 and the fourth baffle plate 34 to rotate, the first slider 17 and the second slider 19 on the third baffle plate 33 respectively slide along the first sliding chute 18 and the second sliding chute 20, and the third slider 21 and the fourth slider 23 on the fourth baffle plate 34 respectively slide along the third sliding chute 22 and the fourth sliding chute 24, so that compared with the case that the third baffle plate 33 and the fourth baffle plate directly slide along the first baffle plate 31 and the second baffle plate 32, the friction force between the third baffle plate 33 and the fourth baffle plate 34 and the first baffle plate 31 and the second baffle plate 32 is reduced, and the rotation process of the third baffle plate 33 and the fourth baffle plate 34 is smoother.

When the tubular pile mould is poured and finished, when the material is supplemented to some places, the first push rod 9 is pushed to one end close to the first discharge port 5 along the pushing groove 8, the first discharge port 5 is blocked by the third bottom plate 10 at the moment, the concrete raw material can only flow out from the second discharge port 6, then the second material supplementing pipe 42 is rotated to the place needing material supplementing, then the first fixing part 431 is upwards rotated, the second fixing part 432 on the second fixing part 432 is clamped on the fixing groove 433, so that the relative positions of the first material supplementing pipe 41 and the second material supplementing pipe 42 are fixed, the concrete raw material flows out from the material supplementing part 4, and the material is supplemented to the tubular pile mould.
