The spherical roadblocks are mostly made of concrete molds.

The present invention processes the inner and outer layers of the concrete spherical roadblock in steps, so that the concrete spherical roadblock can be manufactured using two different materials, thereby reducing the manufacturing cost of the spherical roadblock; and because the spherical roadblock shell is hollow inside, the weight of the spherical roadblock shell is relatively low, so that the spherical roadblock shell can be directly polished and ground during the processing process, and after the spherical roadblock shell is polished and ground, the inner core of the spherical roadblock is filled.

DETAILED DESCRIPTION

[0031] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand: the present invention is further explained below in conjunction with specific implementation methods.

[0032] like Figures 1 to 3 As shown, the present invention provides a technical solution: a spherical concrete roadblock forming machine, comprising a workbench 1, a placing seat 3 is arranged directly above the workbench 1, a spherical shell 4 is placed directly above the placing seat 3, the injection port of the spherical shell 4 faces directly upward, and a deformable spring 5 is symmetrically fixedly connected between the bottom of the placing seat 3 and the top of the workbench 1, and an external manipulator is arranged directly above the workbench 1, and the manipulator is used to place and take out the spherical shell 4, and a feeding assembly and a stirring assembly are arranged directly above the placing seat 3, and the stirring assembly stirs the concrete and then fills the inner core concrete through the feeding assembly, and a stirring transmission assembly and a feeding transmission assembly are arranged on one side of the placing seat 3, the stirring transmission assembly is used to make the placing seat 3 descend during the filling process of the spherical shell 4 and drive the stirring assembly to work, and the feeding transmission assembly is used to control the feeding assembly to stop feeding and filling after the filling is completed.

[0033] During operation: the spherical concrete roadblock is composed of a base, a spherical shell and a solid interior, wherein the purpose of the solid interior filling is mainly to increase the weight and stability of the roadblock so as to improve its ability to resist wind, impact and overturning. During the filling process, the existing device needs to set a stirring mechanism and a feeding mechanism to stir the filled concrete and then feed it, so as to realize the filling process. However, both the stirring mechanism and the feeding mechanism require a power source to control the rotation of the stirring rod and the feeding valve to achieve the filling effect. The operation process is very cumbersome, and during the filling process, it is difficult to judge whether the mass of the filled concrete has reached the range of the mass required to be filled, which is easy to cause overfilling or missing filling. Through the embodiment of the present scheme, during specific use, the spherical shell 4 is first placed directly above the placement seat 3 with the opening facing upwards through an external manipulator. After the spherical shell 4 is just placed, due to the gravity of the spherical shell 4, the placement seat 3 will compress the deformation spring 5 and move downward. During the descent of the placement seat 3, the feeding transmission The moving component drives the unloading component to unload and fill. During the filling process, the spherical shell 4 will gradually become heavier and continue to compress the deformation spring 5 downward. During the placement of the spherical shell 4 and the filling process, the placement seat 3 will descend due to the action of gravity. When the entire placement seat 3 descends, the stirring component will be driven to work through the stirring transmission component, so that the concrete is fully stirred to improve the quality and uniformity of the concrete. During the filling process, the placement seat 3 continues to descend. When the preset compression degree is reached, the unloading component is automatically triggered to close, the unloading of concrete is stopped, and then the spherical shell 4 is taken out by the manipulator for the next step of operation. Through the above embodiment, the gravity of the spherical shell 4 during the placement and filling process is used to control the operation of the unloading component and the stirring component, which can save time and labor costs for manual mixing of concrete, while improving production efficiency and filling consistency. Workers only need to monitor the filling process without continuous manual mixing and control of the unloading valve, which reduces work intensity and improves work efficiency.

[0034] like Figure 3 to Figure 4 As shown, a plurality of fixed seats 2 are fixedly connected directly above the workbench 1, and one side of the plurality of fixed seats 2 is tightly fitted with the outer wall of the spherical shell 4 after placement, wherein two of the fixed seats 2 have inner sliding grooves 12 formed on the inner walls, and sliders 7 are slidably connected to the inner walls of the two inner sliding grooves 12, and one side of the two sliders 7 is fixedly connected with an L-shaped plate 6, and the outer walls of the two L-shaped plates 6 are respectively fitted with the outer wall of the placement seat 3, and one side of one of the sliders 7 is fixedly connected with a telescopic rod 9, and one end of the telescopic rod 9 is fixedly connected with a rack plate 1 10, and one side of the other slider 7 is fixedly connected with a rack plate 2 11.

[0035] During operation: when placing the spherical shell 4 and filling, the placement seat 3 descends. At this time, the descent of the placement seat 3 will drive the slider 7 to descend inside the fixed seat 2 through the L-shaped plate 6. When the slider 7 descends, it will drive the rack plate 10 and the rack plate 2 11 to descend. The descent of the rack plate 10 can move the unloading transmission assembly, thereby controlling the opening and closing of the unloading assembly. The descent of the rack plate 2 11 can move the stirring transmission assembly, thereby allowing the stirring assembly to stir the concrete evenly and prevent the concrete from solidifying.

[0036] like Figures 4 to 5 As shown, both sides of the two sliders 7 are fixedly connected with external blocks 8, the bottoms of the two sliders 7 are fixedly connected with return springs 13, and the other ends of the two return springs 13 are fixedly connected to the bottoms of the inner walls of the two fixing seats 2 respectively.

[0037] During operation: when the placement seat 3 descends, the rack plate 10 and the rack plate 2 11 will be driven to descend through the L-shaped plate 6 and the slider 7. Through the external block 8, when the slider 7 slides on the inner wall of the fixed seat 2, when one end is lowered by gravity, the rack plate 10 and the rack plate 2 11 at the other end will not be lifted up due to uneven force. In addition, through the reset spring 13, after the spherical shell 4 is taken out, the L-shaped plate 6 can be reset to always maintain a fitting relationship with the placement seat 3.

[0038] like Figure 6 to Figure 7 As shown, the stirring transmission assembly includes a gear 15, and the rack plate 2 11 always maintains a meshing relationship with the gear 15 when descending, one end of the gear 15 is fixedly connected to a bevel gear 16, the teeth of the bevel gear 16 are meshed with a bevel gear 2 17, the inner wall of the bevel gear 2 17 is fixedly connected to a rotating rod 18, the top of the rotating rod 18 is fixedly connected to a transmission ring 1 20, the outer wall of the transmission ring 20 is transmission-connected to a transmission belt 1 21, one end of the transmission belt 21 is transmission-connected to a transmission ring 22, and the transmission ring 22 is fixedly connected to the stirring assembly.

[0039] During operation: when rack plate 2 11 descends, it will always maintain a meshing relationship with gear 15, thereby always driving gear 15 to rotate, gear 15 will drive bevel gear 2 17 to rotate through bevel gear 16, the rotation of bevel gear 2 17 will drive transmission ring 1 20 to rotate through rotating rod 18, transmission ring 1 20 will drive transmission ring 2 22 to rotate through transmission belt 1 21, so that transmission ring 2 22 drives the stirring assembly to rotate, through the above embodiment, the effect of always driving the stirring assembly to rotate during the placement of the spherical shell 4 and the filling process is achieved.

[0040] like Figure 6 to Figure 7As shown, the top of the workbench 1 is fixedly connected with a clamping seat 14, the inner wall of the clamping seat 14 is rotatably connected to the shaft connecting the gear 15 and the bevel gear 16, and the bottom of the rotating rod 18 is rotatably connected with a fixed disk 19, which is fixedly installed directly above the workbench 1.

[0041] During operation: the connection relationship between gear 15 and bevel gear 16 is fixed by clamping seat 14, so that gear 15 and bevel gear 16 always maintain a fixed position for rotation, and the position of the rotating rod 18 is fixed by fixing the position of the fixing disc 19, so that bevel gear 16 and bevel gear 2 17 always maintain a meshing relationship.

[0042] like Figures 6 to 8 As shown, the material unloading transmission assembly includes a clamping seat 2 33, and the two connecting shafts of the clamping seat 2 33 are fixedly connected with a gear 2 34 and a transmission ring 4 35, the teeth of the two gears 2 34 are respectively meshed with the teeth of the rack plate 10, and the teeth of the rack plate 10 are one of the four teeth of the gear 2 34, and the outer walls of the two transmission rings 4 35 are both transmission-connected with a transmission belt 2 36, and the end of the transmission belt 2 36 away from the transmission ring 4 35 is transmission-connected with a transmission ring 3 29, and the transmission ring 3 29 is fixedly connected to the material unloading assembly.

[0043] During operation: when the spherical shell 4 is placed, the placement seat 3 will first descend. At this time, the rack plate 10 will first mesh with the upper gear 2 34 and drive the gear 2 34 to rotate 90 degrees. At this time, the rotating gear 2 34 will drive the transmission ring 4 35 on one side to rotate, and drive the transmission ring 3 29 to rotate 90 degrees through the transmission belt 2 36. At this time, the unloading assembly will be opened and the filling work will start. After filling to the preset quality range, the rack plate 10 will mesh with the lower gear 2 34 and drive the lower gear 2 34 to rotate 90 degrees, so that the transmission ring 3 29 will rotate another 90 degrees. At this time, the unloading assembly will be closed to complete the filling operation. It should be noted that if the preset filling quality range needs to be changed, it is only necessary to change the position of the lower gear 2 34 and the transmission ring 4 35 during installation. Through the above embodiment, the effect of being able to drive the unloading assembly to open and close respectively during the placement of the spherical shell 4 and the filling process is achieved.

[0044] like Figures 8 to 9 As shown, the unloading assembly includes a discharge port 28, the opening of the discharge port 28 is located directly above the opening of the spherical shell 4, and the inner wall of the discharge port 28 is provided with a blocking disc 30, one end of the blocking disc 30 is fixedly connected to one end of the transmission ring three 29, and the blocking disc 30 is completely in contact with the inner wall of the discharge port 28 when closed.

[0045] During operation: the blocking disc 30 initially maintains a state of being tightly fitted to the inner wall of the discharge port 28. After the spherical shell 4 is placed, the discharge port 28 will rotate 90 degrees. At this time, the discharge port 28 is in a vertical state, and the material unloading and filling work begins. When the filling is completed, the discharge port 28 will rotate 90 degrees again. At this time, the discharge port 28 is in a blocked state, and the filling work is completed.

[0046] like Figures 8 to 9 As shown, the top of the discharge port 28 is fixedly connected to a mixing box 25, the top of the mixing box 25 is fixedly connected to a feeding bin 26, the outer wall of the mixing box 25 is fixedly connected to a fixed ring 27, the bottom side of the fixed ring 27 is fixedly connected to a fixed platform 31, one end of a transmission ring three 29 is rotatably connected to the fixed platform 31, and the bottom of the fixed platform 31 is fixedly connected to the top of one of the fixed seats 2.

[0047] During operation: the prepared concrete is poured into the feed bin 26, the concrete will flow into the mixing box 25, and after being stirred by the stirring assembly, the concrete will flow into the spherical shell 4 through the discharge port 28 to achieve a filling effect, wherein the fixing ring 27 and the fixing platform 31 fix the position of the mixing box 25.

[0048] like Figures 8 to 9 As shown, the stirring assembly includes a stirring rod 23, which is fixedly connected to the bottom of the transmission ring 22, and a plurality of stirring blades 24 are fixedly connected to the outer wall of the stirring rod 23. The stirring rod 23 and the stirring blades 24 are both located inside the stirring box 25. The top of the transmission ring 22 is rotatably connected to a fixed tube 32, and one end of the fixed tube 32 is fixedly connected to the top of the fixed ring 27.

[0049] During operation: when the stirring transmission assembly drives the transmission ring 22 to rotate, the transmission ring 22 will drive the stirring rod 23 to rotate. When the stirring rod 23 rotates, it will drive the stirring blade 24 to rotate, so that the concrete inside the mixing box 25 is evenly mixed, and the filling quality is better. The fixed pipe 32 fixes the position of the transmission ring 22.

[0050] like Figure 3 to Figure 4 As shown, the top of the workbench 1 and the top inner wall of the fixed seat 2 on one side of the rack plate 10 are fixedly connected with a control button 37, and the control button 37 is used to control the control unit of the telescopic rod 9.

[0051] During operation: after the spherical shell 4 is filled, the rack plate 10 will drop to the bottom and touch the control button 37 on the top of the workbench 1. The control button 37 will control the telescopic rod 9 to retract, and the spherical shell 4 will be taken out so that the rack plate 10 will not mesh with the gear 2 34 when it returns to its original position, preventing the unloading component from being opened during the ascent. When the rack plate 10 reaches the top, it will touch the control button 37 on the top inner side of the fixing seat 2, so that the rack plate 10 returns to its original position and can mesh with the gear 2 34 when it descends.

[0052] When the spherical shell 4 is placed in the upper part of the placing seat 3, the spherical shell 4 will be placed in the upper part of the placing seat 3, and the spherical shell 4 will be placed in the upper part of the placing seat 3. When the spherical shell 4 is placed in the placing seat 3, ...

[0053] When the rack plate 10 descends, the rack plate 10 will first mesh with the upper gear 2 34 and drive the gear 2 34 to rotate 90 degrees.

At this time, the unloading assembly will be closed to complete the filling operation. It should be noted that if the preset filling quality range needs to be changed, it is only necessary to change the position of the lower gear 2 34 and the transmission ring 4 35 during installation.

[0054] When rack plate 2 11 descends, it will always maintain a meshing relationship with gear 15, thereby always driving gear 15 to rotate. Gear 15 will drive bevel gear 2 17 to rotate through bevel gear 1 16. The rotation of bevel gear 2 17 will drive transmission ring 1 20 to rotate through rotating rod 18. Transmission ring 1 20 will drive transmission ring 2 22 to rotate through transmission belt 1 21. Transmission ring 2 22 will drive stirring rod 23 to rotate. When stirring rod 23 rotates, it will drive stirring blade 24 to rotate, so that the concrete inside mixing box 25 is evenly mixed and the filling quality is better.

[0055] Finally, when the spherical shell 4 is filled, the rack plate 10 will drop to the bottom and touch the control button 37 on the top of the workbench 1. The control button 37 will control the telescopic rod 9 to retract, and the spherical shell 4 will be taken out so that the rack plate 10 will not mesh with the gear 2 34 when it returns to its original position, preventing the unloading assembly from being opened during the ascent. When the rack plate 10 reaches the top, it will touch the control button 37 on the top inner side of the fixing seat 2, so that the rack plate 10 returns to its original position and can mesh with the gear 2 34 when it descends.
