The first squeezing roller 74, the second squeezing roller 75 and the third squeezing roller 77 are staggered.

[0022] First, open the mold 3, apply a release agent on the inner surface of the mold 3, then place the steel frame of the concrete pipe in the mold 3, close the mold 3, and use a forklift to install the mold 3 on the top of the swivel seat 2. At this time, the driving component can be started to rotate the swivel seat 2, and the mold 3 can be rotated to the bottom of the first lifting platform 4. Then, the first hydraulic cylinder 12 is started to make the bottom of the first lifting platform 4 fit with the top of the mold 3, and the through hole is facing the mold 3. At this time, the second hydraulic cylinder 13 can be started to drive the second lifting platform 5 to move downward, so that the second lifting platform 5 drives the distribution plate 76 to the inner bottom of the mold 3, and then the concrete mixing equipment can be opened to release the concrete through the soil injection pipe 6. The concrete passes through the through hole. The hole enters the mold 3, and the drive motor 71 is started at the same time, thereby driving the rotating shaft 72 to rotate, so that the first squeezing roller 74, the second squeezing roller 75, the third squeezing roller 77 and the distribution plate 76 throw the concrete toward the inner surface of the mold 3 under the action of centrifugal force and squeeze the concrete. During the squeezing process, the first squeezing roller 74, the second squeezing roller 75 and the third squeezing roller 77 will rotate. At the same time, the second hydraulic cylinder 13 is started to drive the second lifting platform 5 to move upward, so that the second lifting platform 5 drives the first squeezing roller 74, the second squeezing roller 75, the third squeezing roller 77 and the distribution plate 76 to slowly move upward during the rotation process until the distribution plate 76 is withdrawn from the through hole, and then the drive motor 71 and the soil injection pipe 6 can be turned off; Then the first hydraulic cylinder 12 is started to move the first lifting platform 4 upward and return to the initial position. At this time, the driving component is started to rotate the swivel seat 2 to rotate the mold 3 with the concrete pipe out, and the mold 3 with the concrete pipe is transported to the specified position by a forklift. Then the mold 3 can be opened to remove the prepared concrete pipe prefabricated part.

[0023] like Figure 3 and Figure 4As shown, the first lifting platform 4 is fixedly connected with a pushing mechanism 11, which includes a servo motor 111 installed on the outer surface of the first lifting platform 4 through a motor seat, and the output end of the servo motor 111 is fixedly connected to a transmission gear 112, and the top of the first lifting platform 4 is rotatably connected to a material-leveling plate 113, and the bottom of the material-leveling plate 113 is fixedly connected to a gear ring 114, and the gear ring 114 is meshed with the transmission gear 112, and a fixed plate 115 is fixedly connected inside the material-leveling plate 113, and the end of the fixed plate 115 is rotatably connected to a pushing plate 116, and the bottom of the pushing plate 116 is fitted with the inner bottom of the first lifting platform 4, and one end of the pushing plate 116 is fixedly connected to a plurality of cleaning plates 117, and the cleaning plate 117 is made of elastic material. The pushing plate 116 is located on one side of the fixed plate 115 and is fixedly connected to a fixing frame 118, and the fixing frame 118 The inner surface is slidably connected to a slide 119, and the end of the slide 119 is fixedly connected to a push-pull rod 1111, and the outer surface of the push-pull rod 1111 is slidably connected to a fixed cylinder 1110, and one end of the fixed cylinder 1110 is fixedly connected to the inner surface of the material-leveling plate 113. The outer surface of the push-pull rod 1111 located in the fixed cylinder 1110 is sleeved with a fourth spring 1112, and the two ends of the fourth spring 1112 are fixedly connected to the fixed cylinder 1110 and the push-pull rod 1111 respectively, and the end of the push-pull rod 1111 is fixedly connected to a displacement rod 1113, and a displacement groove 1114 is provided in the first lifting platform 4, the displacement rod 1113 passes through the side wall of the material-leveling plate 113 and extends into the displacement groove 1114, and a displacement block 1115 is fixedly connected in the displacement groove 1114, and the displacement rod 1113 is located in the displacement groove 1114 and adapted to the displacement block 1115.

[0024] When the soil injection pipe 6 releases concrete, the servo motor 111 is started, so that the transmission gear 112 drives the ring gear 114 to rotate, and then the material leveling plate 113 rotates. The rotation of the material leveling plate 113 will drive the push plate 116 to rotate through the fixed plate 115 and the push-pull rod 1111, the fixed cylinder 1110, the slide 119 and the fixed frame 118, so as to push the concrete spilled on the bottom of the first lifting platform 4 into the through hole, so that the concrete spilled on the bottom of the first lifting platform 4 can enter the mold 3 in time, thereby preventing the concrete from drying out and affecting the quality of the concrete pipe prefabricated parts prepared by extrusion, saving resources and ensuring the quality of the produced concrete pipe prefabricated parts; During this process, the displacement rod 1113 rotates in the displacement slot 1114. When the displacement rod 1113 rotates to the position of the displacement block 1115, the displacement rod 1113 moves inward under the action of the displacement block 1115, so that the slide 119 pushes the push plate 116 to rotate inward through the fixing frame 118. When the displacement rod 1113 is separated from the position of the displacement block 1115, the push plate 116 is reset under the action of the fourth spring 1112, so that the push plate 116 produces an inward pushing action, pushing the concrete material close to the inner surface of the material leveling plate 113 inward, thereby facilitating the concrete material to better enter the through hole. When preparing the top of the concrete pipe prefabricated part, the first squeezing roller 74, the second squeezing roller 75, the third squeezing roller 77 and the distribution plate 76 will be located in the through hole and gradually withdrawn from the through hole. During this process, when the pushing plate 116 rotates inward, the cleaning plate 117 will be in contact with the outer surfaces of the first squeezing roller 74, the second squeezing roller 75, the third squeezing roller 77 and the distribution plate 76, cleaning the first squeezing roller 74, the second squeezing roller 75, the third squeezing roller 77 and the distribution plate 76 to remove the concrete material adhered to their outer surfaces, thereby preventing the concrete material adhered to the outer surfaces of the first squeezing roller 74, the second squeezing roller 75, the third squeezing roller 77 and the distribution plate 76 from drying when not in use, causing the dried concrete material on the outer surfaces of the first squeezing roller 74, the second squeezing roller 75, the third squeezing roller 77 and the distribution plate 76 to enter the subsequently prepared concrete pipe prefabricated part when it is used again, causing the subsequently prepared concrete pipe prefabricated part to crack, thereby ensuring the quality of the subsequently prepared concrete pipe prefabricated part.

[0025] like Figure 2 、 Figure 5 and Figure 6 As shown, the outer surface of the extrusion mechanism 7 is fixedly connected to a pressure mechanism 9 for extruding the inner wall of the concrete pipe, and the pressure mechanism 9 includes a groove 91 opened on the outer surface of the feeding plate 76, and a limiting groove 92 is opened at the inner top of the groove 91. A moving block 94 is slidably connected in the limiting groove 92, and a fixed rod 93 is fixedly connected in the limiting groove 92. The fixed rod 93 passes through the moving block 94 and is slidably connected to the moving block 94. The outer surface of the fixed rod 93 is sleeved with a second spring 95, and the two ends of the second spring 95 are respectively fixedly connected to the moving block 94 and the limiting groove 92. The bottom of the moving block 94 is rotatably connected to a pressure roller 96, and the pressure roller 96 is located in the groove 91 and fits in the groove 91.

[0026] When the distribution plate 76 is not rotating, the outer surface of the pressure roller 96 is not flush with the outer surface of the distribution plate 76. During the rotation of the distribution plate 76, the pressure roller 96 will generate centrifugal force under the rotation of the distribution plate 76. The pressure roller 96 will move outward under the action of the centrifugal force, thereby driving the moving block 94 to slide outward along the limiting groove 92, stretching the second spring 95, so that the pressure roller 96 generates a greater extrusion force under the action of centrifugal force to extrude the inner surface of the prepared concrete pipe prefabricated part, so that the pressure roller 96 can squeeze the concrete more tightly, thereby further improving the quality of the prepared concrete pipe prefabricated part.

[0027] like Figure 2 and Figure 5 As shown, the extrusion mechanism 7 is fixedly connected to a knocking mechanism 10 for compacting the concrete pipe. The knocking mechanism 10 includes a transmission shaft 101 rotatably connected to the distribution plate 76. The top of the transmission shaft 101 is fixedly connected to the bottom of the second extrusion roller 75. The outer surface of the transmission shaft 101 is fixedly connected to a toothless gear 102. The outer surface of the distribution plate 76 is provided with a sliding bin 105. The bottom of the transmission shaft 101 is rotatably connected to the inner bottom of the sliding bin 105. The inner surface of the sliding bin 105 is fixedly connected to the outer surface of the distribution plate 76. A knocking block 103 is slidably connected, the toothless gear 102 is located inside the knocking block 103, the inner surface of the knocking block 103 is fixedly connected with teeth 104, the teeth 104 are engaged with the toothless gear 102, the inner surface of the sliding bin 105 is fixedly connected with a telescopic rod 106, the telescopic rod 106 is fixedly connected to the knocking block 103, the outer surface of the telescopic rod 106 is sleeved with a third spring 107, and the two ends of the third spring 107 are respectively fixedly connected to the sliding bin 105 and the knocking block 103.

[0028] When the second squeezing roller 75 rotates, the toothless gear 102 will be driven to rotate through the transmission shaft 101, and then during the process of preparing the concrete pipe prefabricated part, the knocking block 103 will reciprocately knock the inner surface of the prepared concrete pipe prefabricated part under the action of the teeth 104, the telescopic rod 106 and the third spring 107, so as to achieve the purpose of compacting the prepared concrete pipe prefabricated part, improve the compactness of the prepared concrete pipe prefabricated part, avoid the inner surface of the prepared concrete pipe prefabricated part from becoming loose and falling off, and ensure the overall strength of the prepared concrete pipe prefabricated part.

[0029] The specific working principle of the present invention is as follows: First, open the mold 3, apply a release agent on the inner surface of the mold 3, then place the steel frame of the concrete pipe in the mold 3, close the mold 3, and use a forklift to install the mold 3 on the top of the swivel seat 2. At this time, the driving component can be started to rotate the swivel seat 2, and the mold 3 can be rotated to the bottom of the first lifting platform 4. Then, the first hydraulic cylinder 12 is started to make the bottom of the first lifting platform 4 fit with the top of the mold 3, and the through hole is facing the mold 3. At this time, the second hydraulic cylinder 13 can be started to drive the second lifting platform 5 to move downward, so that the second lifting platform 5 drives the distribution plate 76 to the inner bottom of the mold 3, and then the concrete mixing equipment can be opened to release the concrete through the soil injection pipe 6, and the concrete enters the mold through the through hole. In the mold 3, the drive motor 71 is started at the same time, thereby driving the rotating shaft 72 to rotate, so that the first squeezing roller 74, the second squeezing roller 75, the third squeezing roller 77 and the distribution plate 76 throw the concrete to the inner surface of the mold 3 under the action of centrifugal force and squeeze the concrete. During the squeezing process, the first squeezing roller 74, the second squeezing roller 75 and the third squeezing roller 77 will rotate. When the second squeezing roller 75 rotates, it will drive the toothless gear 102 to rotate through the transmission shaft 101, and then in the process of preparing the concrete pipe prefabricated part, the knocking block 103 reciprocates and knocks the inner surface of the prepared concrete pipe prefabricated part under the action of the teeth 104, the telescopic rod 106 and the third spring 107, so as to achieve the purpose of compacting the prepared concrete pipe prefabricated part. , improve the compactness of the prepared concrete pipe prefabricated parts, avoid the loosening and falling off of the inner surface of the prepared concrete pipe prefabricated parts, and ensure the overall strength of the prepared concrete pipe prefabricated parts. The work of the servo motor 111 will drive the gear ring 114 to rotate through the transmission gear 112, thereby rotating the material-leveling plate 113. The rotation of the material-leveling plate 113 will drive the push plate 116 to rotate through the fixed plate 115 and the push-pull rod 1111, the fixed cylinder 1110, the slide 119 and the fixed frame 118, and push the concrete spilled on the bottom of the first lifting platform 4 into the through hole, so that the concrete spilled on the bottom of the first lifting platform 4 can enter the mold 3 in time, avoiding the influence of concrete drying on the concrete prepared by extrusion. The quality of the soil pipe prefabricated parts is improved, resources are saved, and the quality of the produced concrete pipe prefabricated parts is guaranteed. During this process, the displacement rod 1113 will rotate in the displacement groove 1114. When the displacement rod 1113 rotates to the position of the displacement block 1115, the displacement rod 1113 will move inward under the action of the displacement block 1115, so that the slide 119 pushes the push plate 116 to rotate inward through the fixed frame 118, and when the displacement rod 1113 is separated from the position of the displacement block 1115, the push plate 116 will be reset under the action of the fourth spring 1112, so that the push plate 116 will produce an inward pushing action, pushing the concrete material close to the inner surface of the material leveling plate 113 inward, thereby facilitating the concrete material to better enter the through hole; At the same time, the pressure roller 96 will generate centrifugal force under the rotation of the distribution plate 76. Under the action of the centrifugal force, the pressure roller 96 will move outward, thereby driving the moving block 94 to slide outward along the limiting groove 92, stretching the second spring 95, so that the pressure roller 96 generates a greater extrusion force under the action of the centrifugal force to squeeze the inner surface of the prepared concrete pipe prefabricated part, so that the pressure roller 96 can squeeze the concrete more tightly, thereby further improving the quality of the prepared concrete pipe prefabricated part; At the same time, the second hydraulic cylinder 13 is activated to drive the second lifting platform 5 to move upward, so that the second lifting platform 5 drives the first squeezing roller 74, the second squeezing roller 75 and the material distribution plate 76 to slowly move upward during the rotation process until the material distribution plate 76 is withdrawn from the through hole, and then the drive motor 71 and the soil injection pipe 6 can be turned off; When preparing the top of the concrete pipe prefabricated part, the first squeeze roller 74, the second squeeze roller 75, the third squeeze roller 77 and the distribution plate 76 will be located in the through hole and gradually withdrawn from the through hole. During this process, when the push plate 116 rotates inward, the cleaning plate 117 will be in contact with the outer surfaces of the first squeeze roller 74, the second squeeze roller 75, the third squeeze roller 77 and the distribution plate 76, cleaning the first squeeze roller 74, the second squeeze roller 75, the third squeeze roller 77 and the distribution plate 76 to remove the concrete material adhered to their outer surfaces. This prevents the concrete material adhered to the outer surfaces of the first squeeze roller 74, the second squeeze roller 75, the third squeeze roller 77 and the distribution plate 76 from drying out when not in use, causing the dried concrete material on the outer surfaces of the first squeeze roller 74, the second squeeze roller 75, the third squeeze roller 77 and the distribution plate 76 to enter the subsequently prepared concrete pipe prefabricated part when it is used again, causing the subsequently prepared concrete pipe prefabricated part to crack, thereby ensuring the quality of the subsequently prepared concrete pipe prefabricated part.

[0030] The above-described embodiments merely illustrate several implementations of the present invention.
