[0011] The water spraying component includes a water spraying reservoir. The side of the water spraying reservoir located outside the conveyor housing is connected to a water supply pipe. The water supply pipe is connected to a water storage tank. One end of the water supply pipe extending into the water storage tank is connected to a water pump. The water pump is connected to a control component.
[0012] The feed drive motor and the main drive motor are respectively connected to the control components.
[0013] This invention also relates to a simple, easy-to-operate, and quantitatively precise method for mixing sand and cement, automatically and continuously outputting the prepared cement slurry, replacing the current cement mortar preparation process. It eliminates the need for manual batching and frequent cleaning, significantly saving time and manpower, and improving the quality of ductile iron pipe lining preparation. The automatic mixing and transportation steps of the described continuous automatic mixing and transportation method are as follows:
[0014] S1. Based on the quality and ratio of cement and sand required for lining different pipe fittings, the feed drive motor of each quantitative feeder controls the speed and ratio of cement and sand entering through the set rotation speed via the control component.
[0015] S2. The control unit controls the rotation speed of the feed drive motor of the main screw mixer conveyor to control the discharge speed of cement mortar.

[0018] S5. Through the continuous operation of the quantitative feeder and the main screw mixer conveyor, the continuous preparation and conveying of cement mortar is realized.
[0019] The working principle and beneficial effects of the technical solution adopted in this invention are as follows:
[0020] The continuous automatic mixing and conveying machine of this invention comprises a main screw conveyor and two metering feeders above it. One metering feeder transports sand, and the other transports cement. Sand and cement fall into the two metering feeders through discharge ports, respectively. Each metering feeder is driven by a feed drive motor to rotate a metering feed screw shaft. The metering feed screw blades, narrow-pitch double screw blades, and reverse feed screw blades rotate synchronously with the feed screw shaft. The metering feed screw blades are used to push the material falling from the hopper forward, the narrow-pitch double screw blades ensure uniform material transport, and the reverse screw blades ensure uniform material transport. The material will not accumulate inside the feeder housing; it will all fall into the conveyor housing of the main spiral mixing conveyor through the feeder discharge port. The main drive motor drives the main spiral mixing shaft to rotate. The main spiral conveying blades, the main mixing spiral blades, and the main reverse spiral blades rotate synchronously with the main spiral mixing shaft. The main spiral conveying blades transport the falling sand and cement forward, while the mixing spiral blades mix the sand and cement and transport them forward. The water spray component mixes the sand and cement to prepare cement mortar. The main spiral shaft and the reverse spiral blades ensure that the cement mortar does not accumulate inside the conveyor housing but is discharged entirely from the main discharge port. The base provides fixed support for the entire equipment. When preparing and conveying cement slurry (a mixture of cement, sand, and water), the quality and ratio of cement and sand required for lining different pipe fittings are determined according to the specific needs. The feed drive motor of each metering feeder is controlled by a control unit to set its speed, thereby controlling the speed and proportion of cement and sand entering the machine. The control unit also controls the rotation speed of the feed drive motor of the main screw conveyor to control the discharge speed of the cement mortar. Each metering feeder's metering feed screw shaft rotates uniformly under the drive of its respective feed drive motor. Through the metering feed screw blades, narrow-pitch double screw blades, and reverse feed screw blades, the material falling from the feed inlet is continuously and evenly conveyed into the conveyor housing of the main screw conveyor. One metering feeder receives cement, while another receives sand. Driven by the main drive motor, the main spiral mixing shaft rotates at a constant speed. The main spiral conveying blades push the falling material forward, while the mixing spiral blades mix and convey the sand and cement forward. Under the control of the control unit, the water spraying component sprays water downwards according to the set flow rate. Cement mortar is prepared under the continuous action of the mixing spiral blades. The mixed cement mortar is continuously conveyed forward and, through the action of the main and reverse spiral blades, falls entirely from the discharge port into the receiving hopper below the discharge port, completing the conveying process. Through the continuous operation of the metering feeders and the main spiral mixing conveyor, continuous preparation and conveying of cement mortar are achieved.The continuous automatic mixing and conveying machine and mixing and conveying method described in this invention have a simple structure and are easy to operate. They can accurately measure the ratio of sand and cement and automatically and continuously output the prepared cement slurry, replacing the current cement mortar preparation process. They no longer require manual batching or frequent cleaning, saving a lot of time and manpower and improving the quality of ductile iron pipe lining preparation. Attached Figure Description

[0025] The following description, with reference to the accompanying drawings, provides a more detailed explanation of the specific embodiments of the present invention, including the shape and structure of each component, the relative positions and connections between the parts, the functions and working principles of each part:
[0026] As attached Figure 1 Appendix Figure 2As shown, the present invention is a continuous automatic mixing conveyor, including a quantitative feeder 12 and a main spiral mixing conveyor 13. A feeding spiral shaft 2 is installed inside the feeder housing 14 of the quantitative feeder 12. One end of the feeding spiral shaft 2 is connected to a feeding drive motor 1 located outside the feeder housing 14. The feeding spiral shaft 2 is equipped with quantitative feeding spiral blades 3, narrow-pitch double spiral blades 4, and feeding reverse spiral blades 5. The narrow-pitch double spiral blades 4 are located between the quantitative feeding spiral blades 3 and the feeding reverse spiral blades 5. A feed inlet 15 is provided on the feeder housing 14 above the quantitative feeding spiral blades 3. The feed inlet 16 below the feed reverse spiral blade 5 is connected to the conveyor housing 18 of the main spiral mixing conveyor 13 located below the feeder housing 14. A main spiral mixing shaft 7 is installed inside the conveyor housing 18. One end of the main spiral mixing shaft 7 is connected to the main drive motor 6 located outside the conveyor housing 18. The main spiral mixing shaft 7 is equipped with a main spiral conveying blade 8, a main mixing spiral blade 9, and a main reverse spiral blade 11. The main mixing spiral blade 9 is located between the main spiral conveying blade 8 and the main reverse spiral blade 11. A main discharge port 19 is provided on the conveyor housing 18 below the main reverse spiral blade 11. To address the shortcomings of the prior art, an improved technical solution is proposed. During the structural setup, a main spiral mixing conveyor 13 is installed, and two metering feeders 12 are installed above the main spiral mixing conveyor 13. One metering feeder 12 conveys sand, and the other metering feeder conveys cement. Sand and cement fall into the two metering feeders through the discharge port, respectively. Each metering feeder is driven by a feeding drive motor to drive the metering feeding spiral shaft 2. The metering feeding spiral blades 3, narrow-pitch double spiral blades 4, and feeding reverse spiral blades 5 rotate synchronously with the feeding spiral shaft 2. The metering feeding spiral blades are used to push the material falling from the hopper forward, the narrow-pitch double spiral blades ensure uniform material conveying, and the reverse spiral blades ensure that the material is properly conveyed. The material will not accumulate inside the feeder housing; it will all fall into the conveyor housing of the main spiral mixing conveyor through the feeder discharge port. The main drive motor drives the main spiral mixing shaft to rotate. The main spiral conveying blades 8, the main mixing spiral blades 9, and the main reverse spiral blades 11 rotate synchronously with the main spiral mixing shaft. The main spiral conveying blades transport the falling sand and cement forward, while the mixing spiral blades mix the sand and cement and transport them forward. The water spray component 10 mixes the sand and cement to prepare cement mortar. The main spiral shaft reverse spiral blades ensure that the cement mortar will not accumulate inside the conveyor housing but will be discharged entirely from the main discharge port. The base provides fixed support for the entire equipment.When preparing and conveying cement slurry (a mixture of cement, sand, and water), the quality and ratio of cement and sand required for lining different pipe fittings are determined according to the specific requirements. The feed drive motor 1 of each quantitative feeder 12 controls the speed and proportion of cement and sand entering the machine via a set rotation speed controlled by a control component. The control component also controls the rotation speed of the feed drive motor 1 of the main spiral mixing conveyor 13 to control the discharge speed of the cement mortar. The quantitative feed spiral shaft 2 of each quantitative feeder 12 rotates uniformly under the drive of its respective feed drive motor 1. Through the quantitative feed spiral blades 3, narrow-pitch double spiral blades 4, and feed counter-spiral blades 5, the material falling from the feed inlet 15 is continuously and evenly conveyed into the conveyor housing 18 of the main spiral mixing conveyor 13. One metering feeder 12 feeds cement, while the other metering feeder 12 feeds sand. The main spiral mixing shaft 7 rotates at a constant speed under the drive of the main drive motor 6. The main spiral conveying blades 8 push the falling material forward, and the mixing spiral blades 9 mix and stir the sand and cement and convey them forward. The water spraying component 10 sprays water downward according to the set water flow rate under the control of the control component. Cement mortar is prepared under the continuous action of the mixing spiral blades 9. The mixed cement mortar is continuously conveyed forward and, under the action of the main and reverse spiral blades 11, falls entirely from the discharge port into the receiving hopper below the discharge port 19, completing the conveying process. Through the continuous operation of the metering feeders and the main spiral mixing conveyor 13, the continuous preparation and conveying of cement mortar is achieved. The continuous automatic mixing and conveying machine of the present invention has a simple structure and is easy to operate. Through ingenious equipment, it can quantitatively and accurately measure the ratio of sand and cement, and automatically and continuously output the prepared cement slurry, replacing the current cement mortar preparation process. It does not require manual batching or frequent cleaning, saving a lot of time and manpower, and improving the quality of cement slurry and the preparation quality of ductile iron pipe linings.
[0027] The conveyor housing 18 of the main spiral mixing conveyor 13 is fixedly installed above the base 20, and the metering feeders 12 are fixedly connected above the conveyor housing 18. In this structure, the base is placed on the ground as a supporting foundation. The conveyor housing 18 of the main spiral mixing conveyor 13 is fixedly connected to the base by bolts or welding. At the same time, the two metering feeders are fixedly connected to the conveyor housing 18 by bolts or welding, thus realizing the support and fixation of the base for the entire continuous automatic mixing conveyor, facilitating the coordinated operation of various components.
[0028] A water spray component 10 is installed above the conveyor housing 18 of the main spiral mixer conveyor 13, positioned above the main mixing spiral blades 9. In this structure, when cement slurry preparation is required, one metering feeder supplies cement according to a set quantity, another metering feeder supplies sand according to a set quantity, and the water spray component supplies water according to a set quantity. In this way, the two materials and water are mixed within the conveyor housing 18 of the main spiral mixer conveyor 13, ensuring that the cement slurry materials are proportioned precisely. This achieves automated proportioning, automated mixing and preparation, and automated conveying.

The feeding drive motor 1 is fixedly connected to the fixed bracket 21, and the fixed bracket 21 is connected to the base 20. In this structure, the feeding screw shaft 2 is reliably connected to the feeder housing and is movably connected to the feeder housing. It is driven to rotate by the feeding drive motor 1, which is mounted on the fixed bracket for fixed installation, so that the feeding drive motor will not rotate or move arbitrarily.
[0030] One end of the main spiral stirring shaft 7 is connected to one side of the conveyor housing 18 via a bearing, and the other end of the main spiral stirring shaft 7 is connected to the other side of the conveyor housing 18 via a bearing, extending to the outside of the conveyor housing 18 to connect to the main drive motor 6. The main drive motor 6 is fixedly connected to the fixed bracket 21. In this structure, the main spiral stirring shaft 7 is reliably connected to the conveyor housing and is movably connected to it, while its rotation is achieved by being driven by the main drive motor 6, which is mounted on the fixed bracket for fixed installation.
[0031] The continuous automatic mixing conveyor includes two metering feeders 12, both fixedly mounted above the conveyor housing 18. The discharge port 16 of each metering feeder 12 is connected to the conveyor housing 18 of the main spiral mixing conveyor 13. One metering feeder is for sand, and the other is for cement. The water spraying component 10 includes a water spraying storage chamber 22. The side of the water spraying storage chamber 22 located outside the conveyor housing 18 is connected to a water supply pipe, which is connected to a water tank. One end of the water supply pipe extending into the water tank is connected to a water pump, which is connected to a control component. In this structure, one metering feeder supplies cement according to a set quantity, the other metering feeder supplies sand according to a set quantity, and the water spraying component supplies water to the conveyor housing according to a set quantity via the controlled water pump. Thus, the two materials and water are mixed within the conveyor housing 18 of the main spiral mixing conveyor 13, ensuring that the cement slurry is proportioned precisely. In this way, automated proportioning is achieved, and the present invention can realize automated mixing preparation and automated delivery.
[0032] The feed drive motor 1 and the main drive motor 6 are respectively connected to the control components.
[0033] This invention also relates to a simple, easy-to-operate, and quantitatively precise method for mixing sand and cement, automatically and continuously outputting the prepared cement slurry, replacing the current cement mortar preparation process. It eliminates the need for manual batching and frequent cleaning, significantly saving time and manpower, and improving the quality of ductile iron pipe lining preparation. The automatic mixing and transportation steps of the described continuous automatic mixing and transportation method are as follows:
[0034] S1. Based on the quality and ratio of cement and sand required for lining different pipe fittings, the feed drive motor 1 of each quantitative feeder 12 controls the speed and proportion of cement and sand entering the machine through a control component by setting the rotation speed. S2. The control component controls the rotation speed of the feed drive motor 1 of the main spiral mixing conveyor 13 to control the discharge speed of cement mortar. The quantitative feed spiral shaft 2 of each quantitative feeder 12 rotates uniformly under the drive of its respective feed drive motor 1. Through the quantitative feed spiral blades 3, narrow-pitch double spiral blades 4, and feed reverse spiral blades 5, the material falling from the feed inlet 15 is continuously and evenly conveyed into the conveyor housing 18 of the main spiral mixing conveyor 13. The material entering and falling from one quantitative feeder 12... The first feeder 12 receives cement, while the second feeder 12 receives sand. S3. The main spiral mixing shaft 7 rotates at a constant speed under the drive of the main drive motor 6. The main spiral conveying blades 8 push the falling material forward, and the mixing spiral blades 9 mix and stir the sand and cement, conveying them forward. The water spraying component 10 sprays water downwards according to the set water flow rate under the control of the control component. Cement mortar is prepared under the continuous action of the mixing spiral blades 9. S4. The mixed cement mortar is continuously conveyed forward, and through the action of the main and reverse spiral blades 11, it falls entirely from the discharge port into the receiving hopper below the discharge port 19, completing the conveying process. S5. Through the continuous operation of the quantitative feeder and the main spiral mixing conveyor 13, continuous preparation and conveying of cement mortar are achieved. The method of this invention achieves automated proportioning, automated mixing preparation, and automated conveying. This completely replaces manual labor, reducing labor intensity.
[0035] The continuous automatic mixing and conveying machine of this invention comprises a main screw conveyor and two metering feeders above it. One metering feeder transports sand, and the other transports cement. Sand and cement fall into the two metering feeders through discharge ports, respectively. Each metering feeder is driven by a feed drive motor to rotate a metering feed screw shaft.

The main spiral conveying blades transport the falling sand and cement forward, while the mixing spiral blades mix the sand and cement and transport them forward. The water spray component mixes the sand and cement to prepare cement mortar. The main spiral shaft and the reverse spiral blades ensure that the cement mortar does not accumulate inside the conveyor housing but is discharged entirely from the main discharge port. The base provides fixed support for the entire equipment. When preparing and conveying cement slurry (a mixture of cement, sand, and water), the quality and ratio of cement and sand required for lining different pipe fittings are determined according to the specific needs. The feed drive motor of each metering feeder is controlled by a control unit to set its speed, thereby controlling the speed and proportion of cement and sand entering the machine. The control unit also controls the rotation speed of the feed drive motor of the main screw conveyor to control the discharge speed of the cement mortar. Each metering feeder's metering feed screw shaft rotates uniformly under the drive of its respective feed drive motor. Through the metering feed screw blades, narrow-pitch double screw blades, and reverse feed screw blades, the material falling from the feed inlet is continuously and evenly conveyed into the conveyor housing of the main screw conveyor. One metering feeder receives cement, while another receives sand. Driven by the main drive motor, the main spiral mixing shaft rotates at a constant speed.
