[0034] Among them, a material discharge groove 3 is opened on the left side of the upper surface of the material guide pipe 1, and rotating blocks 4 are rotatably installed on both sides of the inner wall of the material guide pipe 1, and a material discharge pipe 5 is fixedly installed on the opposite ends of the two rotating blocks 4. A material discharge funnel 6 is fixedly installed on the top of the material discharge pipe 5, and a rotating device is provided at the position of the front surface of the material guide pipe 1 corresponding to the rotating block 4, and the rotating device is used to adjust the angle between the material discharge pipe 5 and the material discharge funnel 6;

[0035] A material guiding device is provided on the inner wall of the material guiding pipe 1, and the material guiding device is used to accelerate the flow of concrete and prevent blockage.

[0036] Furthermore, the driving device includes two fixed blocks 7, which are respectively fixedly mounted on the front and rear surfaces of the material guide tube 1, and the right ends of the two fixed blocks 7 are fixedly mounted with electric push rods 8;

[0037] Wherein, connecting blocks 9 are fixedly installed at the left ends of the front and rear surfaces of the extension tube 2, and the telescopic ends of the two electric push rods 8 are fixedly connected to the two connecting blocks 9 respectively.

[0038] Furthermore, the rotating device includes a first motor 10, which is fixedly mounted on the front surface of the guide tube 1 at a position corresponding to the rotating block 4, and the output shaft of the first motor 10 rotates through the inner wall of the guide tube 1 and is fixedly connected to the front rotating block 4.

[0039] Furthermore, a through hole 12 is provided on the right side of the outer surface of the bottom end of the feed pipe 5;

[0040] Among them, three positioning holes 13 are opened in an arc shape at the positions of the through holes 12 on the front surface of the material guide tube 1, and positioning grooves 14 are opened at the positions of the three positioning holes 13 on the rear surface of the inner wall of the material guide tube 1. Positioning rods 15 are inserted and slidably installed inside the corresponding positioning holes 13 and positioning grooves 14, and the positioning rods 15 pass through the interior of the through holes 12.

[0041] Furthermore, the material guiding device includes two rotating shafts 17, both rotating shafts 17 are rotatably mounted on the bottom end of the inner wall of the material guiding tube 1, and the two rotating shafts 17 are connected by a material guiding belt 18;

[0042] A second motor 11 is fixedly mounted on the front surface of the material guide tube 1 at a position corresponding to the left rotating shaft 17 , and an output shaft of the second motor 11 rotates through the inner wall of the material guide tube 1 and is fixedly connected to the left rotating shaft 17 .

The left ends of the three high-pressure water gun heads 19 are fixedly installed with connecting pipes 20 communicated with the interior thereof. When using the present device, in order to allow concrete to quickly flow out of the interior of the guide pipe 1, the guide pipe 1 and the extension pipe 2 are in an inclined state, and their inclination angles need to be adjusted according to the actual use site. When the inclination angles of the guide pipe 1 and the extension pipe 2 change, the angles of the discharge pipe 5 and the discharge funnel 6 relative to the guide pipe 1 should also change accordingly, so that the opening directions of the discharge pipe 5 and the discharge funnel 6 are always kept perpendicular to the ground, and the first motor 10 is started. The output shaft of the first motor 10 rotates to drive the front rotating block 4 to rotate, so that the two rotating blocks 4 drive the discharge pipe 5 to flip.

[0044] Working principle: When using this device, in order to make the concrete flow out quickly from the inside of the guide pipe 1, the guide pipe 1 and the extension pipe 2 are in an inclined state, and their inclination angles need to be adjusted according to the actual use site. When the inclination angles of the guide pipe 1 and the extension pipe 2 change, the angles of the discharge pipe 5 and the discharge funnel 6 relative to the guide pipe 1 should also change accordingly, so that the opening directions of the discharge pipe 5 and the discharge funnel 6 are always kept perpendicular to the ground.

[0045] Start the first motor 10, and the output shaft of the first motor 10 rotates to drive the front rotating block 4 to rotate, so that the two rotating blocks 4 drive the discharge pipe 5 to flip. It should be noted that the power of the first motor 10 is relatively small, so that its rotation rate is relatively slow. The discharge pipe 5 is rotated to a suitable position and the discharge pipe 5 is clamped on the corresponding positioning hole 13 and positioning groove 14 by using the positioning rod 15. Then, the concrete is poured into the interior of the guide pipe 1 through the discharge pipe 5 and the discharge funnel 6. Start the second motor 11, and the output shaft of the second motor 11 rotates to drive the left rotating shaft 17 to rotate. The left rotating shaft 17 rotates and drives the right rotating shaft 17 to rotate through the guide belt 18, and the rotation direction is clockwise, so that the concrete is discharged to the right end of the guide pipe 1 under the rotation of the guide belt 18, avoiding the problem of concrete accumulation inside the guide pipe 1 causing blockage, thereby improving the discharge rate of the device.

[0046] By setting a high-pressure water gun head 19 and a connecting pipe 20, after the unloading is completed, the external water pipe is connected to the connecting pipe 20, and the upper surface of the guide belt 18 and the inner wall of the guide pipe 1 are washed by three high-pressure water gun heads 19 to avoid residual concrete from affecting the next unloading process, thereby ensuring that each unloading process can proceed smoothly, improving production efficiency and ensuring product quality.
