Description

Technical Field

[0001] The utility model relates to the technical field of concrete mixing equipment, in particular to a mixed fiber concrete mixing device. Background Art

[0002] Hybrid fiber concrete is a special type of concrete in which different types of fiber materials, such as steel fibers, polymer fibers, etc., are added to improve its performance and durability. These fibers form a three-dimensional network structure in the concrete, which can effectively control cracking and increase tensile strength, thereby improving the performance of concrete. The uniform dispersion of fibers is one of the key factors to ensure the performance of concrete. Through the mixing device, the fibers can be evenly dispersed in the concrete to avoid fiber agglomeration or uneven distribution, thereby ensuring the overall performance of the concrete.

[0003] The utility model patent with announcement number CN214871625U discloses a mixing device for mixed fiber concrete, which relates to the technical field of concrete mixing equipment. The mixing device for mixed fiber concrete includes a mixing barrel body and a base for fixing the mixing barrel body. A motor is provided on the top of the mixing barrel body, and the motor output shaft is connected to a stirrer, which is arranged in the mixing barrel body; the stirrer includes a stirring shaft connected to the motor output shaft and a stirring rod fixedly connected to the stirring shaft; an inverted L-shaped scraper is provided on the stirring shaft; and a dust removal device is also included. The utility model can scrape the raw material residue on the inner wall of the mixing barrel body by setting an inverted L-shaped scraper; by setting a dust removal device, when dust is generated in the mixing barrel body, the water pump works, and spray water is sprayed out from the spray hole in an umbrella shape, so that the dust in the mixing barrel body is wetted and falls, thereby preventing the dust in the mixing barrel body from polluting the surrounding working environment.

[0004] However, the concrete attached to the scraper and the mixing device in the above-mentioned patent is not convenient to clean. If the concrete is not cleaned in time, it will solidify on the mixing device and the scraper, thereby affecting the mixing effect and the cleaning effect of the scraper. Utility Model Content

[0005] The utility model aims to provide a mixed fiber concrete mixing device to address the deficiencies of the prior art, which is convenient for cleaning the concrete remaining inside to avoid affecting the subsequent mixing.

[0006] The technical scheme adopted by the utility model is a mixed fiber concrete mixing device, comprising a tank body, a discharge port is provided at the bottom of the tank body, a sealing cover is provided on the top of the tank body, a support frame is fixedly installed on the surface of the tank body, support legs integrally formed with the support frame are provided at the four corners of the support frame, fixed columns are fixedly installed on both sides of the tank body, the bottom of the fixed column is fixedly connected with the top of the support frame, the fixed column is a hollow structure, a movable column is slidably installed inside the fixed column, a lifting device is provided in the movable column and the fixed column, a cross bar integrally formed with the movable column is provided on the top of the movable column, a card slot is provided in the cross bar, a fixed plate is contacted and connected in the card slot, through holes are provided on the fixed plate and the surface of the cross bar, bolts are threadedly connected in the through holes, and a mixing device is provided in the fixed plate.

[0007] Preferably, the lifting device includes a threaded hole, which is opened in the movable column. A threaded column is threadedly connected to the threaded hole. A worm wheel integrally formed with the threaded column is provided at the bottom of the threaded column. A worm is rotatably connected to one side of the worm wheel. One end of the worm is fixedly connected to a first motor through a wall of the fixed column. The stator part of the first motor is fixedly installed on the top of the support frame.

[0010] Preferably, a sealing strip is fixedly installed at the contact point between the sealing cover and the tank body.

[0011] Preferably, a magnetic coupler is fixedly installed at the connection between the second motor rotor and the transmission column.

[0019] like Figure 1 As shown, a hybrid fiber concrete mixing device comprises a tank body 1, a discharge port 12 is provided at the bottom of the tank body 1, a sealing cover 15 is provided at the top of the tank body 1, a support frame 13 is fixedly installed on the surface of the tank body 1, and support legs 14 formed integrally with the support frame 13 are provided at the four corners of the support frame 13, fixed columns 2 are fixedly installed on both sides of the tank body 1, the bottom of the fixed column 2 is fixedly connected to the top of the support frame 13, the fixed column 2 is a hollow structure, a movable column 3 is slidably installed inside the fixed column 2, a lifting device 4 is provided in the movable column 3 and the fixed column 2, and a movable column 3 is provided on the top of the movable column 3. A cross bar 31 is provided with a card slot in the cross bar 31, and a fixing plate 32 is contacted and connected in the card slot. Through holes are provided on the surfaces of the fixing plate 32 and the cross bar 31, and bolts 33 are threadedly connected in the through holes. A stirring device 5 is provided in the fixing plate 32, and a mounting block 6 is fixedly installed at the bottom of the support leg 14, and a mounting hole 61 is provided on the surface of the mounting block 6. The device can be fixedly installed by setting fixing tools such as screws in the mounting hole. A sealing strip is fixedly installed at the contact between the sealing cover 15 and the tank body 1. The sealing strip can be made of rubber or other materials with good sealing effect to prevent dust from leaking out during stirring.

[0020] like Figure 2 and Figure 3The lifting device 4 shown includes a threaded hole 41, which is opened in the movable column 3. A threaded column 42 is threadedly connected to the threaded hole 41. A worm wheel 43 integrally formed with the threaded column 42 is provided at the bottom of the threaded column 42. A worm 44 is rotatably connected to one side of the worm wheel 43. One end of the worm 44 passes through a wall of the fixed column 2 and is fixedly connected to a first motor 45. The stator portion of the first motor 45 is fixedly installed on the top of the support frame 13. The stirring device 5 includes a second motor 51. The stator portion of the second motor 51 is fixedly installed on the top of the fixed plate 32. The rotor portion of the second motor 51 passes through the fixed plate 32 and is fixedly connected to a transmission column 52. The transmission column 52 passes through the sealing cover 15 and enters the interior of the tank body 1. The transmission column 52 is rotatably connected to the sealing cover 15 through a bearing. A plurality of stirring blocks 53 are fixedly installed on the surface of the transmission column 52 located inside the tank body 1.

This model is overloaded. When the pressure is too high, the connection can be disconnected to protect the second motor 51. In actual use, it is only necessary to start the first motor 45. The rotation of the first motor 45 drives the worm 44 to rotate, and the rotation of the worm 44 drives the worm wheel 43 to rotate, thereby driving the threaded column 42 to rotate in the threaded hole 41, so that the height of the movable column 3 rises, and the rising height of the movable column 3 drives the stirring device 5 and the sealing cover 15 to rise. At this time, the mixed fiber concrete to be stirred can be poured into the tank body 1, and then the first motor 45 is reversed to lower the height of the stirring device 5 and the sealing cover 15. When the sealing cover 15 contacts the top of the tank body 1, the second motor 51 can be started. The rotation of the second motor 51 drives the transmission column 52 to rotate, and then drives the stirring block 53 to rotate, thereby stirring the mixed fiber concrete in the tank body 1. After the stirring is completed, when the stirring device 5 and the tank body 1 need to be cleaned, it is only necessary to control the movable column 3 to rise to a suitable height, and then unscrew the bolt 33 to disassemble the stirring device 5 for easy cleaning.
