[0021] ​In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] The following is combined Figures 1 to 2 This utility model will be described in detail.

[0023] A cement discharge control device includes a main body 1, an inlet 101 on one side of the main body 1, a storage pipe 102 at the bottom of the main body 1, a hydraulic rod 2 connected inside the storage pipe 102, a piston disc 201 at the top of the hydraulic rod 2, a laser rangefinder 202 near the bottom of the piston disc 201, a conveying pipe 3 connected to the middle of the main body 1, a discharge pipe 4 connected to the top of the conveying pipe 3, and a rotating component connected to the outer side of the top of the conveying pipe 3. The rotating component is driven to rotate the conveying pipe 3.

[0024] First, cement slurry is poured into the main body 1 through the feed inlet 101. Then, the extension and retraction of the hydraulic rod 2 in the storage pipe 102 drives the piston disc 201 to move, thereby drawing the slurry in the main body 1 and storing it in the storage pipe 102. Then, by aligning the delivery pipe 3 with the opening of the storage pipe 102, the movement of the hydraulic rod 2 forces the piston disc 201 to squeeze and discharge the slurry into the delivery pipe 3, and then discharge it through the discharge pipe 4. After the slurry in the storage pipe 102 is discharged, the angle of the delivery pipe 3 is adjusted by rotation to align it with another storage pipe 102 for discharge. At the same time, while the storage pipe 102 that has been discharged is discharging, the hydraulic rod 2 will draw the slurry in the main body 1 for re-storage through the other storage pipe. By repeatedly drawing and discharging the slurry through the two storage pipes 102 and adjusting the angle of the delivery pipe 3 to connect to different storage pipes 102, the slurry can be continuously and stably discharged.

[0025] Furthermore, the delivery pipe 3 is inclined, the bottom end of the delivery pipe 3 is engaged with the storage pipe 102, the top of the delivery pipe 3 is a vertically protruding pipe on the outside of the top of the main body 1, two storage pipes 102 are arranged side by side at the bottom of the main body 1, and the laser rangefinder 202 is electrically connected to the external control terminal.

[0026] Meanwhile, when the hydraulic rod 2 moves, the distance between it and the hydraulic cylinder is detected by the laser rangefinder 202 at the bottom of the piston disc 201. The distance is then transmitted to the controller via an electrical signal to determine how much slurry has been discharged from the storage pipe 102. This allows for better control of the slurry discharge volume and prevents the discharge volume from exceeding the limit due to uncontrollable residue in the discharge pipe 4.

[0027] Furthermore, the rotating assembly includes a drive motor 103, a drive gear 1031, a transmission ring 301, a roller 302, and a positioning rod 303. The drive motor 103 is located on the top of the body 1, the drive gear 1031 is connected to the bottom of the drive motor 103, the transmission ring 301 is located on the top side wall of the conveying pipe 3, the roller 302 is connected to the side wall of the transmission ring 301, the positioning rod 303 is a round rod located on one side of the top of the transmission ring 301, the transmission ring 301 is located on the outer side of the portion of the top of the conveying pipe 3 that penetrates the body 1, and the top of the transmission ring 301 is also provided with a disc protrusion that meshes with the tooth marks of the drive gear 1031, the roller 302 is a round shaft with a protruding portion located on the inner wall of the penetration opening of the transmission ring 301, and the discharge pipe 4 also includes a connecting cylinder 401, which is located at one end of the discharge pipe 4, and the discharge pipe 4 is threadedly engaged with the annular groove at the top of the conveying pipe 3 through the connecting cylinder 401 at one end.

[0028] Meanwhile, the angle adjustment of the conveying pipe 3 is achieved by rotating the drive motor 103 to drive the drive gear 1031 to rotate. The drive gear 1031 meshes with the disk on the transmission ring 301 at the top of the main body 1, causing the transmission ring 301 to start rotating. When the transmission ring 301 rotates, it also drives the conveying pipe 3 to rotate, so that the conveying pipe 3 rotates around the part connected to the transmission ring 301 at the top as the axis, thereby adjusting the connection to the openings of different storage tubes 102. A positioning rod 303 is also provided on the top of the disk on the transmission ring 301. The position of the rotating conveying pipe 3 can be determined by the angle change of the positioning rod 303, so that it can be more conveniently and accurately connected to different storage tubes 102.

[0029] The following is a detailed implementation process of this utility model: First, cement slurry is poured into the main body 1 through the inlet 101. Then, the extension and retraction of the hydraulic rod 2 in the storage pipe 102 drives the piston disc 201 to move, thereby drawing the slurry in the main body 1 and storing it in the storage pipe 102. Next, the delivery pipe 3 is aligned with the opening of the storage pipe 102, and the movement of the hydraulic rod 2 forces the piston disc 201 to squeeze and discharge the slurry into the delivery pipe 3. Then, it is discharged through the discharge pipe 4. After the slurry in the storage pipe 102 is discharged, the angle of the delivery pipe 3 is adjusted by rotation to align it with another storage pipe 102 for further discharge. Meanwhile, the already discharged storage pipe 102 is in another... Simultaneously with discharge, the hydraulic rod 2 draws in the slurry within the main body 1 and stores it. By reciprocating the suction and discharge through two storage pipes 102 and adjusting the angle of the delivery pipe 3 to connect to different storage pipes 102, the slurry can be continuously and stably discharged. At the same time, when the hydraulic rod 2 moves, the laser rangefinder 202 at the bottom of the piston disc 201 detects the distance to the hydraulic cylinder and transmits it to the controller via an electrical signal to determine how much slurry has been discharged from the storage pipe 102. This allows for better control of the slurry discharge rate and prevents the discharge rate from exceeding the discharge limit due to uncontrollable residue in the discharge pipe 4. The system can be shut off in advance based on the discharge rate.

[0030] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
