[0023] In the description of the present invention, unless otherwise specified, the meaning of "a plurality" is two or more.

[0024] In the description of the present utility model, it should be noted that unless otherwise clearly specified and defined, the terms "installation", "connection", and "coupling" shall be understood in a broad sense. For example, it may be a fixed connection, a detachable connection, or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0025] Please refer to Figure 1 and Figure 2 , the present utility model provides a cement slurry distribution mechanism, including a hopper 1 and a peristaltic discharging assembly; the peristaltic discharging assembly includes a discharging driving member 2, a rotating member 3, a discharging hose 4, and an arc-shaped elbow 5;

[0026] The bottom of the hopper 1 is provided with a discharging port, one end of the discharging hose 4 is detachably connected to the discharging port, the arc-shaped elbow 5 is arranged below the hopper 1, the other end of the discharging hose 4 is inserted into the arc-shaped elbow 5 and extends along the arc-shaped elbow 5;

[0027] The discharging driving member 2 is arranged on one side of the arc-shaped elbow 5, and the rotating member 3 is connected to the driving end of the discharging driving member 2; a plurality of radially protruding rollers 6 are uniformly installed around the outer circumference of the rotating member 3. The rollers 6 are arranged along the axial direction of the rotating member 3 and are rotatably installed on the rotating member 3 around the axis, and the rollers 6 are tangent to adjacent rollers 6; a relief opening 51 is provided on the inner arc side of the arc-shaped elbow 5; as the rotating member 3 rotates, the rollers 6 sequentially pass through the relief opening 51 and abut against the outer side wall of the discharging hose 4.

[0028] The viscosity of the cement slurry is high and the discharging amount is unstable. The cement slurry distribution mechanism realizes the purpose of peristaltic discharging through the cooperation of the discharging driving member 2, the rotating member 3, the discharging hose 4, and the arc-shaped elbow 5, making the discharging of the cement slurry stable and controllable, and enabling more accurate control of the discharging amount, so that the texture of the cement slurry is stable and the decorative effect is good; moreover, the equipment is simple, easy to operate and install, and easy to clean.

[0029] The arc-shaped elbow 5 can well support the discharging hose 4 so as not to deviate. In a specific embodiment of the present utility model, the discharging hose 4 is fixed by limit rings at the discharging port of the hopper 1 and the discharging port of the arc-shaped elbow 5, so as to realize detachable connection, so that the discharging hose 4 will not deviate greatly during the extrusion of the slurry.

[0030] The hopper 1 is used to load the cement slurry. The discharging principle of the discharging driving member 2, the rotating member 3, the discharging hose 4 and the arc-shaped elbow 5 can refer to the existing peristaltic pump. The discharging driving member 2 is specifically a motor, which is used to drive the rotating member 3 to rotate around its own rotating shaft. The rotating member 3 will drive the roller 6 to rotate around the rotating shaft of the rotating member 3. As the rotating member 3 rotates, the roller 6 on the rotating member 3 passes through the avoidance opening 51 and abuts against the outer side wall of the discharging hose 4. Subsequently, the roller 6 moves away from the discharging hose 4; the roller 6 cooperates with the arc-shaped elbow 5 to achieve the purpose of squeezing the discharging hose 4, so as to move the cement slurry in the discharging hose 4 towards the discharging port of the discharging hose 4; through the cooperation of multiple rollers 6 on the rotating member 3, the cement slurry can be extruded from the discharging hose 4 to achieve the purpose of quantitative discharging.

[0031] Optionally, convex ribs 61 arranged axially are circumferentially distributed on the inner side wall of the arc-shaped elbow 5 and / or the outer side wall of the roller 6. The convex ribs 61 are used to contact the discharging hose 4, and the top of the cross section of the convex ribs 61 is an arc line.

[0032] Compared with the roller 6 with a smooth side wall, the roller 6 with convex ribs 61 in this embodiment reduces the contact area between the roller 6 and the discharging hose 4, reduces the wear of the roller 6 on the discharging hose 4, and improves the service life of the discharging hose 4. Moreover, since the convex ribs 61 are arranged axially along the roller 6, the convex ribs 61 still maintain a completely cut-off extrusion of the discharging hose 4 during the rotation of the roller 6, making the flow control more accurate and the structure simpler and more stable.

[0033] Furthermore, an auxiliary discharging assembly 7 is further included. The auxiliary discharging assembly 7 is arranged between the hopper 1 and the peristaltic discharging assembly, and includes an auxiliary driving member 70 and a first eccentric wheel group. The first eccentric wheel group includes a first eccentric wheel 71 and a second eccentric wheel 72; the first eccentric wheel 71 and the second eccentric wheel 72 have the same structure, and the axes of the first eccentric wheel 71 and the second eccentric wheel 72 do not coincide with the rotating shaft; the auxiliary driving member 70 is provided with a first driving end and a second driving end. The rotating shaft of the first eccentric wheel 71 is connected to the first driving end of the auxiliary driving member 70, and the rotating shaft of the second eccentric wheel 72 is connected to the second driving end of the auxiliary driving member 70; the discharging hose 4 passes through the gap between the first eccentric wheel 71 and the second eccentric wheel 72;

[0034] The first eccentric wheel 71 and the second eccentric wheel 72 include a tangent state and a separated state. The first eccentric wheel 71 and the second eccentric wheel 72 rotate around the rotation axis towards the side of the discharge hose 4, causing the first eccentric wheel 71 and the second eccentric wheel 72 to switch between the tangent state and the separated state; when the first eccentric wheel 71 and the second eccentric wheel 72 are in the tangent state, the first eccentric wheel 71 and the second eccentric wheel 72 simultaneously press tightly against the discharge hose 4; when the first eccentric wheel 71 and the second eccentric wheel 72 are in the separated state, the first eccentric wheel 71 and the second eccentric wheel 72 simultaneously move away from the discharge hose 4.

[0035] The auxiliary drive member 70 drives the first eccentric wheel 71 to rotate around its own rotation axis through the first drive end, and the auxiliary drive member 70 drives the second eccentric wheel 72 to rotate around its own rotation axis through the second drive end, thereby causing the first eccentric wheel 71 and the second eccentric wheel 72 to switch between the tangent state and the separated state.

[0036] The first eccentric wheel 71 and the second eccentric wheel 72 mainly function as valves and for downward extrusion feeding; the distance between the first eccentric wheel 71 and the second eccentric wheel 72 should be such that the trajectories do not overlap when the first eccentric wheel 71 and the second eccentric wheel 72 rotate, to prevent the first eccentric wheel 71 and the second eccentric wheel 72 from colliding during rotation.

[0037] When the first eccentric wheel 71 and the second eccentric wheel 72 are in the tangent state, the distance between the first eccentric wheel 71 and the second eccentric wheel 72 is the smallest, causing the first eccentric wheel 71 and the second eccentric wheel 72 to simultaneously press tightly against the discharge hose 4, and the discharge hose 4 is compressed to the flattest. At this time, the cement slurry cannot continue to fall, achieving the purpose of stopping the cement slurry from flowing out of the hopper 1 further, and functioning as a valve; when the first eccentric wheel 71 and the second eccentric wheel 72 switch from the tangent state to the separated state, the first eccentric wheel 71 and the second eccentric wheel 72 gradually move away from the discharge hose 4, and the discharge hose 4 gradually resumes its original state, thereby achieving the purpose of loosening the discharge hose 4 and enabling the cement slurry to gradually flow out of the hopper 1; when the first eccentric wheel 71 and the second eccentric wheel 72 are in the separated state, the distance between the first eccentric wheel 71 and the second eccentric wheel 72 is the largest, and the cement slurry can flow in the discharge hose 4; subsequently, the first eccentric wheel 71 and the second eccentric wheel 72 switch from the separated state to the tangent state and finally reach the tangent state; immediately afterwards, the first eccentric wheel 71 and the second eccentric wheel 72 switch from the tangent state to the separated state again, repeating in this way until the auxiliary drive member 70 stops operating.

[0038] The viscosity of the cement slurry is high. The first eccentric wheel 71 and the second eccentric wheel 72 rotate around the rotation axis towards one side of the discharge hose 4. When the first eccentric wheel 71 and the second eccentric wheel 72 continuously switch between the tangent state and the separated state, the cement slurry can be pushed downward, which can accelerate the flow rate of the cement slurry in the discharge hose 4 and avoid the problem of unstable discharge volume caused by too slow flow rate of the cement slurry.

[0039] Furthermore, the auxiliary discharge assembly 7 includes a second eccentric wheel group. The structure of the second eccentric wheel group is the same as that of the first eccentric wheel group, and the second eccentric wheel group is located below the first eccentric wheel group; the second eccentric wheel group includes a third eccentric wheel 73 and a fourth eccentric wheel 74, and the auxiliary driving member 70 is further provided with a third driving end and a fourth driving end; the rotation axis of the third eccentric wheel 73 is connected to the third driving end of the auxiliary driving member 70, and the rotation axis of the fourth eccentric wheel 74 is connected to the fourth driving end of the auxiliary driving member 70; the discharge hose 4 passes through the gap between the third eccentric wheel 73 and the fourth eccentric wheel 74.

[0040] The second eccentric wheel group is the same as the first eccentric wheel group, except for the installation position. The auxiliary driving member 70 drives the third eccentric wheel 73 to rotate around its own rotation axis through the third driving end, and the auxiliary driving member 70 drives the fourth eccentric wheel 74 to rotate around its own rotation axis through the fourth driving end. The working principle and effect of the second eccentric wheel group are the same as those of the first eccentric wheel group, which will not be elaborated here. By setting the second eccentric wheel group, the flow rate of the cement slurry can be further increased.

[0041] In a specific embodiment of the present invention, when the third eccentric wheel 73 and the fourth eccentric wheel 74 are in the tangent state, the first eccentric wheel 71 and the second eccentric wheel 72 are in the separated state; when the third eccentric wheel 73 and the fourth eccentric wheel 74 are in the separated state, the first eccentric wheel 71 and the second eccentric wheel 72 are in the tangent state; the second eccentric wheel group and the first eccentric wheel group alternately enter the tangent state / separated state, preventing mutual interference between the two groups of eccentric wheel groups and affecting the conveying of the cement slurry, which is beneficial to the flow of the cement slurry. When any one of the second eccentric wheel group and the first eccentric wheel group enters the tangent state, it can prevent the cement slurry from continuing to flow out of the hopper 1.

[0042] Specifically, it further includes a discharge ramp 8. The discharge ramp 8 is located below the arc-shaped elbow 5, and the discharge end of the arc-shaped elbow 5 faces the top of the discharge ramp 8.

[0043] The mold is arranged at the bottom of the discharge ramp 8. When the cement slurry is extruded from the discharge hose 4, it flows onto the discharge ramp 8 and then slowly flows onto the mold. Through the discharge ramp 8, the cement slurry can flow slowly to form a casting texture.

[0044] Specifically, the inclination angle of the discharge slope 8 is 30-45°. The inclination angle of the lower trough is 30-45°, which can make the cement slurry flow slowly and form a better casting effect. The inclination angle can be selected according to the cement slurry or the required casting effect.

[0045] Optionally, a discharge hopper 9 is provided at the bottom of the discharge slope 8. The discharge hopper 9 can better guide the cement slurry into the mold, avoiding the problem that the cement slurry cannot completely fall into the mold due to its large inertia when flowing.

[0046] The technical principle of the present invention is described above in combination with specific embodiments. These descriptions are only for explaining the principle of the present invention and cannot be interpreted as limiting the protection scope of the present invention in any way. Based on the explanations here, technicians in this field can think of other specific implementations of the present invention without creative work, and these equivalent variations or substitutions are all included in the scope defined by the claims of this application.
