Description

Technical Field

[0001] This utility model belongs to the field of building engineering technology, and specifically relates to a building engineering mixing device. Background Technology

[0002] Construction engineering refers to the engineering entity formed by the construction of various types of buildings and their ancillary facilities, as well as the installation of supporting lines, pipelines, and equipment. Among them, "buildings" refer to projects with roofs, beams, columns, walls, foundations, and the ability to form internal spaces to meet people's needs for production, living, learning, and public activities. In the construction area, it is often necessary to mix building materials such as concrete, cement, putty powder, and paint in barrel-shaped containers evenly, which requires the use of construction engineering mixing equipment.

[0003] Noise is a particularly prominent issue in the use of modern construction mixing equipment. This is mainly due to the collision of materials during mixing, the high-speed rotation of the mixing blades, and the friction of mechanical transmission components. The resulting noise levels often far exceed urban construction noise limits (such as nighttime construction noise, which should be controlled below 55 decibels). Excessive noise can not only cause irreversible damage to the hearing of operators but also easily lead to complaints from nearby residents. Furthermore, equipment noise without sound insulation measures can exacerbate the deterioration of the construction site's acoustic environment and affect communication efficiency. Utility Model Content

[0004] (1) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a construction engineering mixing device that aims to solve the particularly prominent noise problem in existing technologies. This noise is mainly caused by the collision of materials during the mixing process, the high-speed rotation of the mixing blades, and the friction of mechanical transmission components. The resulting noise levels often far exceed the urban construction noise limit standards (such as nighttime construction noise needing to be controlled below 55 decibels). Excessive noise can not only cause irreversible damage to the hearing of operators but also easily lead to complaints from nearby residents. In addition, equipment noise without sound insulation measures can exacerbate the deterioration of the construction site's acoustic environment and affect communication efficiency.

[0006] (2) Technical solution

[0007] To solve the above-mentioned technical problems, this utility model provides a construction engineering mixing device, including a base frame, a mixing drum installed in the upper center of the base frame, a mixing motor installed in the upper center of the mixing drum, a discharge valve installed on a discharge pipe on one side of the mixing drum, a sound insulation and noise reduction mechanism jointly installed on the upper and both sides of the base frame, the sound insulation and noise reduction mechanism including two guide frames, and a dustproof mechanism jointly installed inside and outside the two guide frames, an alignment transmission assembly jointly installed in the middle of the two guide frames and the upper part of the base frame, the alignment transmission assembly including two pairs of guide support frames, and a sound insulation half cover fixed at the end of each of the two pairs of guide support frames, and a sealing joint assembly installed on the inner side of the two sound insulation half covers.

[0008] Furthermore, the alignment transmission assembly includes a dual-head motor, which is installed in the middle of one of the guide frames. Both ends of the dual-head motor are connected to transmission screws, and the corresponding sections of the two transmission screws are screwed with screw sleeves. Guide support frames are fixed on both sides of the bottom of the two soundproof half-enclosures, and side support frames are fixed on the corresponding sides of the two soundproof half-enclosures. Movable guide wheels are fitted below the ends of the two side support frames.

[0009] Furthermore, the guide support frame and its guide mount frame are connected by a movable guide connection.

[0010] Furthermore, the soundproof half-cover includes a perforated plate, and the outside of the perforated plate is covered with sound-absorbing cotton, and a damping steel plate is provided on the outside of the sound-absorbing cotton.

[0011] Furthermore, the sealing assembly includes a bracket, which is fixed to the inner end of one of the soundproof half-enclosures, and the inner end of the other soundproof half-enclosure has a slot. A sealing strip is installed at the end of the bracket and the inner end of the slot.

[0012] Furthermore, the dustproof mechanism includes an air duct, which is located above the guide frame. Dust blowing heads are provided at the bottom end of the air duct. An assembly frame is installed on one side of the guide frame, and a fan is installed on one side of the middle part of the assembly frame.

Protective pipe covers are installed on both sides of the middle part of the guide frame, and magnetic blocks are connected to the ends of the protective pipe covers.

[0013] Furthermore, the magnetic block at the end of the protective tube cover forms a magnetic fixed connection with the ferromagnetic area at the opposite end of the corresponding guide support frame.

[0014] (3) Beneficial effects

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention allows workers to feed building materials such as concrete, cement, putty powder, and paint into the upper feeding area of ​​the mixing drum. Then, a double-headed motor within one of the guide frames is activated, causing the drive screws at both ends to rotate. This causes the corresponding screw sleeves, acting in conjunction with the two guide frames, to move a pair of soundproof half-covers and two sets of guide supports relative to each other. To ensure stable displacement of the pair of soundproof half-covers, side supports and movable guide wheels are provided at their ends. After displacement, the pair of soundproof half-covers are joined together, with the inserts and slots on their inner sides fitting together. The sealing strips on each half effectively assist in achieving a sealed effect for the combined cover. In this state, the mixing motor can be activated to stir the building materials within the mixing drum. The soundproof half-covers are structurally composed of an outer damping steel plate providing structural strength and an inner perforated plate guiding sound waves into the sound-absorbing cotton. Through frictional dissipation of sound energy, noise isolation is achieved.

[0017] When the transmission screw of this utility model is in use, the operator can start the fan. At this time, the air force filtered by the filter screen will be introduced into the air duct and blown out through multiple dust blowers, thereby blowing away dust from the surface of the transmission screw and reducing the impact of dust in the building environment on the screw. When not in use, the transmission screw drives a pair of soundproof half-covers to close, which not only protects the mixing drum but also allows the screw sleeve corresponding to the guide support frame to fit against the two sides of the middle of the guide frame. At this time, the operator can pull the protective tube cover to stretch it, and the magnetic block at the end of the protective tube cover will magnetically fit against the ferromagnetic area set on the opposite side of the guide frame to form a fixed shape. In this state, the protective tube cover can achieve all-round dust protection for the screw. Attached Figure Description

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.

[0025] This specific embodiment is a mixing device for construction engineering, and its structural schematic diagram is shown below.

A positioning transmission assembly 52 is jointly mounted in the middle of the two guide frames 51 and on the upper part of the base frame 1. The positioning transmission assembly 52 includes a double-headed motor 521, and the double-headed motor 521 is mounted in the middle of one of the guide frames 51. The two ends of the double-headed motor 521 are connected to transmission screws 522, and the two transmission screws 522 are connected to the two guide frames 51. A screw rod sleeve 523 is screwed around the periphery of the opposite section of the screw rod 522. Guide support frames 524 are fixed to both sides of the bottom end of the two soundproof half-covers 53, and side support frames 525 are fixed to the opposite sides of the two soundproof half-covers 53. Movable guide wheels 526 are fitted below the ends of the two side support frames 525. The guide support frames 524 and their guide brackets 51 are connected by a movable guide connection. Soundproof half-covers 53 are fixed to the ends of the two pairs of guide support frames 524 respectively. Each soundproof half-cover 53 includes a perforated plate 53a, and sound-absorbing cotton 53b is attached to the outer side of the perforated plate 53a. A damping steel plate 53c is provided on the outer side of the sound-absorbing cotton 53b. A sealing joint assembly 54 is installed on the inner side of the two soundproof half-covers 53. The sealing joint assembly 54 includes... A bracket 541 is fixed to the inner end of one of the soundproof half-enclosures 53. A slot 542 is provided at the inner end of the other soundproof half-enclosure 53. Sealing strips 543 are installed at the end of the bracket 541 and the inner end of the slot 542. Workers can feed concrete, cement, putty powder, paint, and other building materials to be mixed from the upper feeding area of ​​the mixing drum 2. Then, the double-headed motor 521 inside one of the guide frames 51 can be started to rotate the transmission screws 522 at both ends. The corresponding screw sleeves 523 acting on these two screws can then move relative to a pair of soundproof half-enclosures 53 and two sets of guide supports 524 in coordination with the guide frames 51. To ensure the relative displacement of the pair of soundproof half-enclosures 53... The displacement of the cover 53 is stable.

After the displacement is completed, the pair of soundproof half covers 53 will be joined together. The inserts 541 and slots 542 on the inner side of each pair of soundproof half covers 53 will fit together. The sealing strips 543 provided by each will effectively assist in achieving the sealing effect of the composite cover. In this state, the personnel can start the stirring motor 3 to make the stirring rod in the stirring drum 2 stir the building materials. At this time, the structure of the soundproof half cover 53 is composed of an outer damping steel plate 53c to provide structural strength and an inner perforated plate 53a to guide sound waves into the sound-absorbing cotton 53b. The sound energy is dissipated through friction, thereby achieving the noise isolation effect.

[0026] The dustproof mechanism 6 includes an air duct 61 located above the guide frame 51. Dust blowing heads 62 are located at the bottom of the air duct 61. An assembly frame 63 is installed on one side of the guide frame 51, and a fan 64 is installed on one side of the middle of the assembly frame 63. A filter frame 65 is installed at the end of the middle section of the assembly frame 63. Protective pipe covers 66 are installed on both sides of the middle section of the guide frame 51, and magnetic blocks 67 are connected to the ends of the protective pipe covers 66. The magnetic blocks 67 at the ends of the protective pipe covers 66 are magnetically fixed to the ferromagnetic areas at the opposite ends of the corresponding guide support frame 524. When the transmission screw 522 is in use, personnel can start the fan 64, at which time the dust filtered by the filter frame 65... The wind is introduced into the air duct 61 and blown out through multiple dust blowers 62, thereby blowing away dust from the surface of the transmission screw 522 and reducing the impact of dust in the building environment on the screw. When not in use, the transmission screw 522 drives a pair of soundproof half-covers 53 to close, which not only protects the mixing drum 2 but also allows the screw sleeve 523, which is driven by the transmission screw 522, to fit against the guide support frame 524 on both sides of the middle of the guide frame 51. At this time, personnel can pull the protective tube cover 66 to stretch it, and the magnetic block 67 at the end of the protective tube cover 66 magnetically attaches to the ferromagnetic area set on the opposite side of the guide frame 51 to form a fixed position. In this state, the protective tube cover 66 can achieve all-round dust protection for the screw.

[0027] Working Principle: Workers can feed building materials such as concrete, cement, putty powder, and paint into the upper feeding area of ​​the mixing drum 2. Then, the double-headed motor 521 inside one of the guide frames 51 can be activated, causing the transmission screws 522 at both ends to rotate. This causes the corresponding screw sleeves 523, acting on the two screws, to move a pair of soundproof half-covers 53 and two sets of guide supports 524 relative to each other, guided by the two guide frames 51. To ensure stable displacement of the pair of soundproof half-covers 53, side supports 525 and movable guide wheels 526 are provided at the ends of the pair. After displacement, the pair of soundproof half-covers 53 will engage, with the inserts 541 and slots 542 on the inner sides of each half-cover 53 fitting together. The sealing strips 543 on each half-cover effectively assist in achieving a sealing effect for the combined cover. In this state, the mixing motor 3 can be activated to stir the building materials inside the mixing drum 2. At this time, the structure of the soundproof half-covers 53... The outer damping steel plate 53c provides structural strength, while the inner perforated plate 53a guides sound waves into the sound-absorbing cotton 53b. Sound energy is dissipated through friction, thus achieving noise isolation. Furthermore, when the drive screw 522 is in use, personnel can start the fan 64. At this time, the airflow filtered by the filter frame 65 is guided into the air duct 61 and blown out through multiple dust blowers 62, thereby removing dust from the surface of the drive screw 522 and reducing the impact of dust from the building environment on the screw. When not in use... At this time, the transmission screw 522 drives a pair of soundproof half-covers 53 to close, which not only protects the stirring drum 2 but also allows the screw sleeve 523, which is driven by the transmission screw 522, to fit against the guide support frame 524 on both sides of the middle of the guide frame 51. At this time, personnel can pull the protective tube cover 66 to stretch it, and make the magnetic block 67 at the end of the protective tube cover 66 magnetically fit against the ferromagnetic area set on the opposite side of the guide frame 51 to form a fixed position. In this state, the protective tube cover 66 can achieve all-round dust protection for the screw.
