Description

Technical Field

[0001] The present invention relates to the technical field of concrete mixing devices, and in particular to a concrete mixing device and a use method thereof. Background Art

[0002] Concrete is a commonly used building material. Concrete is formed by mixing mixed materials such as sand, cement, and water with gravel. Different sizes of gravel can also be used to mix concrete of different qualities. Most concrete mixing devices in the prior art cannot independently screen the gravel, resulting in operators having to screen gravel of different sizes and types by themselves when they need them, which increases labor. Summary of the invention

[0003] In view of the deficiencies in the prior art, the object of the present invention is to provide a concrete mixing device and a method of using the same to solve the above problems.

[0004] In view of this, the present invention provides a concrete mixing device, including a mixing barrel, a support foot arranged at the bottom of the mixing barrel, and an opening and closing structure arranged at the bottom of the mixing barrel for discharging concrete, including:

[0005] A first pipe, one end of which is connected to the inner wall of the mixing barrel, and the other end of which is located on the outer wall of the mixing barrel;

[0006] The stone screening device comprises a large stone output structure connected to the first pipe, a small stone output structure connected to the outer wall of the mixing barrel, and screening mechanisms rotatably connected to the large stone output structure and the small stone output structure respectively;

[0007] A stirring device is arranged at the top opening of the stirring barrel;

[0008] Among them, a through hole for inputting small stones into the output structure is provided on the side wall of the mixing barrel. When stones need to be input, the screening mechanism screens the input stones and transports the small stones into the small stone output structure and the large stones into the large stone output structure.

[0009] By adopting the above technical scheme, the required mixed materials are first put into the mixing barrel, the stone screening device is started, and then the stones are put into the screening mechanism. The screening mechanism rotates to screen the stones, and the large stones are moved into the large stone output structure, and the small stones are moved into the small stone output structure. At this time, the operator can control the large stone output structure to transport the large stones into the mixing barrel alone according to the needs, and can control the small stone output structure to transport the small stones alone according to the needs. When large stones and small stones are needed at the same time, they are directly put in from the mixing barrel. By putting in large stones alone, the strength and stability of the concrete can be increased. The use of large stones can also reduce the shrinkage rate of concrete, reduce the cracking and cracking of the concrete surface, and can enhance the bearing capacity and durability of the concrete. By putting in small stones alone, the use of part of the cement can be replaced, the amount of cement can be reduced, and the cost can be reduced. The voids in the concrete can also be filled to increase the density of the concrete. When the concrete requirement is not large, the stone is directly put in from the opening of the mixing barrel. After the stone is put in, the mixing device is started to mix the stone with the mixed material, thereby completing the concrete processing. By screening the size of the stone independently, the labor force can be greatly reduced.

[0010] In the above technical solution, the small stone output structure further comprises:

[0011] A second pipe is connected to the outer wall of the mixing barrel, and an opening of one end of the first pipe away from the mixing barrel is located in the second pipe;

[0012] A first hydraulic cylinder, a fixed end of which is disposed on the outer wall of the mixing barrel and is located below the second pipe, and an output end of which extends toward the second pipe;

[0013] A first baffle, connected to an output end of the first hydraulic cylinder;

[0014] Among them, a through hole is provided on the side wall of the mixing barrel for stones in the second pipe to enter the mixing barrel, and a through hole is provided at the bottom end of the second pipe for the first baffle to pass through. The first baffle extends into the through hole through the first hydraulic cylinder to complete the second pipe, and the second pipe is located outside an output end of the screening mechanism.

[0015] In the present technical solution, by setting up the second pipe, the screening mechanism can screen out small stones for collection. When the first baffle plate does not pass through the first hydraulic cylinder and enters the through hole, the small stones can roll out through the through hole. When the first baffle plate extends into the through hole through the first hydraulic cylinder, the small stones can enter the mixing barrel through the second pipe.

[0016] In the above technical solution, the large stone output structure further comprises:

[0017] A third pipeline, one end of which is connected to the opening of the first pipeline, and the other end of which is connected to the other output end of the screening mechanism, and the third pipeline is located inside the second pipeline;

[0018] A first rotating motor is arranged at the top of the second pipe, and an output end thereof passes through the second pipe and the third pipe and is connected to the third pipe;

[0019] and a second baffle disposed in the third pipe and connected to the output end of the first rotating motor;

[0020] Wherein, the second baffle blocks the flow of the third pipeline or opens the third pipeline through the first rotating motor.

[0021] In the present technical solution, by setting up the third pipe, the large stones selected by the screening mechanism can be collected, by setting up the second baffle, the large stones can be blocked to prevent circulation, and by setting up the first rotating motor, the second baffle can be rotated, and the large stones can flow in the third pipe and enter the mixing barrel.

[0022] In the above technical solution, the screening mechanism further comprises:

[0023] A rotating ring is rotatably connected to an end of the second pipe facing away from the mixing barrel;

[0024] A driving ring connected to an end of the rotating ring facing away from the second pipe;

[0025] A first driving motor, with a fixed end disposed on the outer side wall of the second pipe and an output end extending toward the outer side wall of the driving ring;

[0026] A driving tooth, arranged on an output end of the first driving motor;

[0027] and a screening structure, one end of which is rotatably connected to the inner wall of the third pipe and the other end of which is connected to the opening of the driving ring;

[0028] Among them, a transmission tooth meshing with the driving tooth is provided on the outer wall of the driving ring, and the stones enter the screening structure through the opening of the driving ring. The screening structure rolls the large stones into the third pipe and the small stones into the second pipe by rotation.

[0029] In the present technical solution, by setting the rotating ring, the driving ring can rotate more stably, and by the cooperation of the driving teeth and the transmission teeth, the first driving motor can drive the driving ring to rotate, so that the screening structure rotates to separate large stones and small stones.

[0030] In the above technical solution, the screening structure further comprises:

[0031] A screening pipe, one end of which is rotatably connected to the inner wall of the third pipe, and the other end of which is connected to the opening of the driving ring;

[0033] A plurality of screening hole groups are arranged annularly and spaced apart on the inner wall of the screening pipe, and the screening hole groups are respectively spaced apart between a plurality of inclined blocks;

[0034] Among them, the plurality of screening hole groups include a plurality of screening holes, and the plurality of screening holes are respectively arranged between two inclined blocks at intervals along the length direction of the inclined block.

[0035] In the present technical solution, when a stone enters the screening pipe, the screening pipe rotates. Since the screening pipe is inclined, the stone slowly moves toward the end of the screening pipe. When the stone rolls, due to the rotation of the screening pipe, the stone passes through the screening holes one after another. Therefore, when the stone is small, it falls out of the screening pipe from the screening hole. When some small stones do not pass through the screening holes, the inclined block drives the stone to rotate toward the top of the screening pipe. When it rotates to a certain height, the stone falls and moves next time, thereby solving the problem of missed small stones not moving into the screening holes.

[0036] In the above technical solution, the stirring device further comprises:

[0037] The plug-in ring block is plugged into the top of the mixing barrel;

[0038] A connecting pipe, one end of which is connected to the end of the plug-in ring block away from the mixing barrel, and the other end of which extends away from the mixing barrel;

[0039] A plurality of rotating rods, each having one end located in the mixing barrel and the other end passing through the connecting pipe;

[0040] A plurality of stirring components are respectively arranged on a plurality of rotating rods and are located in the stirring barrel;

[0041] The mobile driving mechanism has a fixed end disposed on the connecting pipe and a driving end connected to the rotating rods;

[0042] and a rotating mechanism, which is arranged on the mobile driving mechanism and has a driving end connected to the rotating rod;

[0043] Wherein, second hydraulic cylinders are provided on both sides of the mixing barrel, and the output ends of the two second hydraulic cylinders are connected to the side walls of the connecting pipe. The moving drive mechanism drives the rotating rod to move in the mixing barrel, and the rotating mechanism is used to drive the rotating rod to rotate.

[0044] In the present technical solution, by setting the plug-in ring block, the connecting pipe can be supported more stably, by setting the second hydraulic cylinder, the connecting pipe can be raised and lowered, so that the mobile drive mechanism and the rotating mechanism can be raised, so that the mixed material can be put into water, by setting the rotating rod, the stirring assembly can be stirred, by setting the mobile drive mechanism, the stirring assembly can be moved in the stirring barrel, and by setting the rotating mechanism, the stirring assembly can perform stirring work.

[0045] In the above technical solution, the mobile driving mechanism further comprises:

[0046] A limiting plate is rotatably connected to the end of the connecting pipe away from the mixing barrel, and the limiting plate is provided with a plurality of strip-shaped holes arranged in a ring shape around the central axis of the limiting plate;

[0047] A movable plate is rotatably connected to an end of the limiting plate away from the connecting pipe, and the movable plate is provided with a plurality of driving holes arranged in a circumferential direction with respect to the central axis of the movable plate, and the driving holes are connected to the outer wall of the movable plate;

[0048] and two second driving motors, the fixed ends of which are both connected to the outer side wall of the connecting pipe, and the output ends of which extend toward the limiting plate and the moving plate respectively;

[0050] In the present technical solution, when the rotating rod needs to move in the strip hole, the speed of the second driving motor driving the moving disk is greater than or less than the second driving motor driving the limiting disk. At this time, the speed of the moving disk is greater than or less than the limiting disk, and a position difference is generated between the driving hole and the strip hole, so that the rotating rod moves in the strip hole, and finally the position of the stirring assembly is moved to achieve the mixing of concrete at different positions. When the moving disk and the limiting disk do not rotate, the position of the rotating rod will not change. When the speeds of the moving disk and the limiting disk are the same, the rotating rod rotates in the direction of the central axis of the mixing barrel. The different positions of the rotating rod can achieve the best mixing effect, and the changes in different periods can be controlled. The different positions of the rotating rod increase the overall mixing effect. For example, the rotating rod will not move at the beginning, and the mixing assembly is mixed within the range. When the mixing within the range is completed, the rotating rod moves in the strip hole for mixing, so that concrete in different diameters of the mixing barrel is mixed. Finally, when the rotating rod rotates about the central axis of the mixing barrel, the entire mixing barrel is mixed and stirred.

[0056] A plurality of third driving motors, the fixed ends of which are arranged at the top of the connecting barrel, and the output ends of which penetrate through the connecting barrel and are located inside the connecting barrel;

[0057] Among them, arc-shaped limiting grooves for sliding balls are provided on the inner walls on both sides of the sliding groove, and limiting grooves for sliding balls are provided on both sides of the inner walls of the sliding groove. The rotating rod passes through the bottom opening of the connecting rod and is connected to the output end of the third driving motor.

[0112] Embodiment 5:
