Description

Technical Field

[0001] This utility model relates to the field of precast concrete components technology, specifically a mixing device for producing precast concrete components. Background Technology

[0002] Precast concrete components are building components made of concrete and produced in factories in a standardized manner. They include structural load-bearing components such as beams, slabs, columns, and shear walls, as well as municipal landscape components such as stairs and pipe corridors. The main materials of precast concrete components include cement, sand, gravel, and water, as well as various auxiliary materials. The raw materials of precast concrete components are mixed using mixing equipment.

[0003] According to Chinese utility model application number CN202422158558.4, a concrete preparation mixing device is proposed. The utility model describes that "the mixing device has a rotatable vertical cylinder inside the tank through a drive mechanism. The mixing plate is connected to both sides of the vertical cylinder through a horizontal shaft. By using the cooperation of worm gear, worm wheel, connecting shaft, rotating shaft and handle, the angle of the horizontal shaft can be adjusted, thereby adjusting the set angle of the mixing plate, so that it can better adapt to the fluidity, viscosity, density and other characteristics of different materials. At the same time, a limit mechanism is set. By using the cooperation of tension spring and positioning shaft, the rotating shaft is limited by the handle to ensure the stability of the adjustment component structure when the drive mechanism is running."

[0004] The concrete preparation mixing device uses a mixing plate to mix the raw materials for precast concrete components. The mixed raw materials are discharged to the outside of the tank through a discharge pipe. When there is too much moisture in the raw materials, they tend to stick to the inside of the discharge pipe, causing the pipe diameter to shrink and resulting in blockage. This affects the material feeding effect and needs to be improved. Therefore, a mixing device for the production of precast concrete components is proposed to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a mixing device for the production of precast concrete components, which has advantages such as easy unblocking of blockages. It solves the problem that when there is too much moisture in the raw materials, the raw materials tend to stick to the inside of the discharge pipe, causing the diameter of the discharge pipe to shrink and resulting in blockage, which affects the material feeding effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a mixing device for producing precast concrete components, comprising a tank, a feed pipe connected to the top of the tank, a valve fixedly installed on the outside of the feed pipe, a discharge pipe connected to the bottom of the tank, a mixing mechanism for mixing materials connected inside the tank, a lifting mechanism connected to the side wall of the discharge pipe, and a clearing mechanism sealed inside the discharge pipe. The lifting mechanism is used to drive the clearing mechanism to lift and lower, and the clearing mechanism is used to clear the concrete inside the discharge pipe. The unblocking mechanism includes an unblocking block, the shape of which matches the shape of the discharge pipe. A first unblocking plate and a second unblocking plate are fixedly installed on the top of the unblocking block. The tops of the first unblocking plate and the second unblocking plate are both conical. A sealing element is fixedly installed on the outside of the unblocking block. The sealing element is made of corrosion-resistant material. A guide groove is provided on the top of the unblocking block.

[0007] Furthermore, the mixing mechanism includes a first motor, which is fixedly connected to the top of the tank. The output end of the first motor passes through the tank and is fixedly mounted with a rotating shaft. Multiple mixing rods are fixedly mounted on the outside of the rotating shaft.

[0008] Furthermore, the lifting mechanism includes a chamber body, which is fixedly connected to the side wall of the discharge pipe. A second motor is fixedly installed on the top of the chamber body. The output end of the second motor passes through the chamber body and is fixedly installed with a threaded rod. A threaded sleeve is installed on the external thread of the threaded rod. A connecting rod is fixedly installed on the side wall of the threaded sleeve. A lifting plate is fixedly installed on the side wall of the connecting rod. The unblocking block is detachably connected to the top of the lifting plate.

[0009] Furthermore, the bottom of the threaded rod is rotatably connected to the inner bottom wall of the chamber via a bearing, and the threaded sleeve is threadedly connected to the threaded rod via a threaded hole.

[0010] Furthermore, the side wall of the compartment is provided with a movable hole, which matches the connecting rod, and the connecting rod is Z-shaped.

[0011] Furthermore, an mounting plate is fixedly installed on the top of the lifting plate, and the mounting plate is threadedly connected to the unblocking block by bolts.

[0012] Compared with the prior art, the technical solution of this application has the following beneficial effects: This mixing equipment for producing precast concrete components consists of a tank, an inlet pipe, an outlet pipe, a mixing mechanism, a lifting mechanism, and a clearing mechanism. First, cement, sand, gravel, water, and various auxiliary materials are poured into the inlet pipe in appropriate proportions. Then, the mixing mechanism mixes the raw materials. After mixing, the lifting mechanism lowers the clearing mechanism to a designated position, releasing the seal on the outlet pipe. The raw materials are then discharged through the outlet pipe to the outside of the tank. When the outlet pipe becomes blocked, the lifting mechanism reciprocates, clearing the blockage and improving the material discharge efficiency. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-7This embodiment of a mixing device for producing precast concrete components includes a tank 1, a feed pipe 2 connected to the top of the tank 1, a valve fixedly installed on the outside of the feed pipe, a discharge pipe 3 connected to the bottom of the tank 1, a mixing mechanism 4 for mixing materials connected inside the tank 1, a lifting mechanism 5 connected to the side wall of the discharge pipe 3, and a clearing mechanism 6 sealed inside the discharge pipe 3. The lifting mechanism 5 is used to drive the clearing mechanism 6 to lift and lower, and the clearing mechanism 6 is used to clear the concrete inside the discharge pipe 3.

[0017] Specifically, the workers first pour cement, sand, gravel, water, and various auxiliary materials into the feed pipe 2 in appropriate proportions. Then, the mixing mechanism 4 is used to mix the raw materials of the precast concrete components. After the raw materials are mixed, the lifting mechanism 5 is used to drive the unblocking mechanism 6 to descend to the designated position, so that the unblocking mechanism 6 releases the seal on the discharge pipe 3. The raw materials are discharged to the outside of the tank 1 through the discharge pipe 3. When the discharge pipe 3 is blocked, the lifting mechanism 5 is used to drive the unblocking mechanism 6 to move up and down repeatedly. The unblocking mechanism 6 unblocks the blockage and improves the material discharge efficiency.

[0018] In this embodiment, the mixing mechanism 4 includes a first motor 41, which is fixedly connected to the top of the tank 1. The output end of the first motor 41 passes through the tank 1 and is fixedly installed with a rotating shaft 42. Thirty mixing rods 43 are fixedly installed on the outside of the rotating shaft 42. The thirty mixing rods 43 are divided into five layers, and each layer is evenly and equidistantly distributed. The six mixing rods 43 in each layer are evenly and equidistantly distributed in a ring.

[0019] Specifically, by turning on the first motor 41, the first motor 41 drives the rotating shaft 42 and the mixing rod 43 to rotate, and the mixing rod 43 mixes the raw materials of the precast concrete components.

[0020] In this embodiment, the lifting mechanism 5 includes a chamber 51, which is fixedly connected to the side wall of the discharge pipe 3. A second motor 52 is fixedly installed on the top of the chamber 51. The output end of the second motor 52 passes through the chamber 51 and is fixedly installed with a threaded rod 53. The bottom of the threaded rod 53 is rotatably connected to the inner bottom wall of the chamber 51 through a bearing. A threaded sleeve 54 is installed on the outer thread of the threaded rod 53. The threaded sleeve 54 is threadedly connected to the threaded rod 53 through a threaded hole. Two connecting rods 55 are symmetrically fixedly installed on the side wall of the threaded sleeve 54. Two moving holes are opened on the side wall of the chamber 51. The two moving holes are respectively matched with the two connecting rods 55. The two connecting rods 55 are both Z-shaped. The two connecting rods 55 are each composed of three rods, and the three rods are parallel to the X, Y, and Z axes respectively. A lifting plate 56 is fixedly installed on the side wall of the two connecting rods 55.

[0021] Specifically, by activating the second motor 52, the second motor 52 drives the threaded rod 53 to rotate, and the threaded rod 53 drives the threaded sleeve 54, the connecting rod 55 and the lifting plate 56 to rise and fall.

[0022] In this embodiment, the unblocking mechanism 6 includes an unblocking block 61, the shape of which matches the shape of the discharge pipe 3. An mounting plate is fixedly installed on the top of the lifting plate 56, and the mounting plate is threadedly connected to the unblocking block 61 by bolts. Multiple first unblocking plates 62 and multiple second unblocking plates 63 are fixedly installed on the top of the unblocking block 61. The tops of the first unblocking plates 62 and the second unblocking plates 63 are both conical, and the directions of the first unblocking plates 62 and the second unblocking plates 63 are perpendicular to each other. A sealing element 64 is fixedly installed on the outside of the unblocking block 61. The sealing element 64 is made of a corrosion-resistant material, specifically fluororubber, and the surface of the sealing element 64 is coated with a wear-resistant coating, specifically a ceramic coating. A guide groove is opened on the top of the unblocking block 61, and the cross-section of the guide groove is arc-shaped.

[0023] Specifically, both the unblocking block 61 and the discharge pipe 3 are rectangular in shape. The sealing element 64 is fitted to the inner wall of the discharge pipe 3 for sealing. Since the raw material will damage the sealing element 64, the entire unblocking mechanism 6 needs to be replaced periodically. When the lifting plate 56 moves the unblocking block 61 down to the designated position, the raw material is discharged along the guide channel. When the lifting plate 56 moves the unblocking block 61, the first unblocking plate 62 and the second unblocking plate 63 up and down, the first unblocking plate 62 and the second unblocking plate 63 unblock the blockage.

[0024] The working principle of the above embodiments is as follows: First, the workers pour cement, sand, gravel, water, and various auxiliary materials into the feed pipe 2 in a suitable ratio. Then, they turn on the first motor 41, which drives the rotating shaft 42 and the mixing rod 43 to rotate. The mixing rod 43 mixes the raw materials of the precast concrete components. After the raw materials are mixed, the second motor 52 is turned on, which drives the threaded rod 53 to rotate. The threaded rod 53 drives the threaded sleeve 54, the connecting rod 55, the lifting plate 56, and the unblocking block 61 to descend to the designated position. The raw materials are discharged to the outside of the tank 1 along the guide channel. When the discharge pipe 3 is blocked, the second motor 52 is turned on again, which drives the threaded rod 53 to rotate. The threaded rod 53 drives the threaded sleeve 54, the connecting rod 55, the lifting plate 56, the unblocking block 61, the first unblocking plate 62, and the second unblocking plate 63 to move up and down repeatedly. The first unblocking plate 62 and the second unblocking plate 63 unblock the blockage, improving the material discharge efficiency.
