Description

Technical Field

[0001] The utility model relates to the technical field of building engineering, in particular to a dust removal mechanism. Background Art

[0002] Mixing devices in construction projects are usually used for mixing and stirring concrete, mortar and other materials. The main purpose is to ensure that the materials meet the specified uniformity and quality standards. However, a large amount of dust is easily generated during the process of using a mixing barrel to stir concrete, mortar and other materials.

[0003] Therefore, when using a mixing barrel, it is necessary to equip it with a matching dust removal device. The function of these dust removal mechanisms is to effectively control the dust generated during the mixing process to ensure the health of workers and the cleanliness of the environment.

[0004] However, most of the existing mixing barrel dust removal mechanisms use bag dust collectors, which use filter bags to intercept dust during the mixing process, effectively reducing the dust concentration in the air. This method is simple and effective, and it is convenient to collect dust. However, due to the structural design of the mixing barrel, a certain opening space is always reserved in the mixing barrel, so the dust cannot be effectively collected. In addition, when the bag dust collector is full during use, the dust collection effect will be reduced, which will reduce work efficiency.

[0005] Therefore, the utility model proposes a dust removal mechanism. Utility Model Content

[0006] The purpose of the utility model is to solve the shortcomings in the prior art and to provide a dust removal mechanism.

[0007] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a dust removal mechanism, comprising a mounting base plate, a rotating seat is arranged on the top of the mounting base plate, a driving assembly is rotatably connected to the rotating seat, a roller assembly is arranged on one side of the driving assembly, and a sealing cover is arranged at the top opening of the roller assembly;

[0008] The driving assembly includes an equipment frame, which is rotatably connected to a rotating seat, one end of the equipment frame is rotatably connected to a second connecting piece, the other end of the equipment frame is slidably connected to a first connecting piece, a connecting rod is arranged between the second connecting piece and the first connecting piece, a driving frame is arranged at one end of the connecting rod close to the second connecting piece, a driving gear is rotatably connected to the driving frame, auxiliary gears are rotatably connected to both sides of the driving gear on the driving frame, the other end of the equipment frame is provided with a limiting frame at one end of the connecting rod close to the first connecting piece, and a limiting roller is rotatably connected to the limiting frame.

[0009] As a preferred embodiment, the roller assembly includes a cylinder, a limiting ring is arranged near the opening of the cylinder, the cylinder is movably connected to the limiting roller through the limiting ring, and a tooth groove is opened at the bottom of the cylinder, and the tooth groove is meshed with the auxiliary gear and the driving gear.

[0010] The beneficial effect of adopting the above further scheme is that the cylinder is limited by the mutual clamping between the limiting sleeve and the limiting roller to prevent the cylinder from being separated from the equipment frame during rotation, and further the tooth groove is meshed with the auxiliary gear and the driving gear, so that the driving gear can drive the cylinder to rotate under the action of the tooth groove when rotating, so as to tumble and mix the concrete, mortar and other materials inside it.

[0011] As a preferred embodiment, a flip plate is rotatably connected to the inner center of the drum assembly, and a lifting plate is provided on the inner wall of the cylinder. There are three lifting plates in total, and the three lifting plates are distributed in a ring shape, and the angles between two adjacent lifting plates are equal.

[0012] The beneficial effect of adopting the above-mentioned further scheme is: through the design of the flip plate, when the cylinder rotates, the flip plate contacts the concrete, mortar and other materials inside the cylinder and then rotates, thereby accelerating the mixing processing of concrete, mortar and other materials, and under the action of the lifting plate, when the cylinder rotates, part of the concrete, mortar and other materials can be lifted and dropped by the lifting plate, thereby further improving the mixing efficiency.

[0013] As a preferred embodiment, an air pump is arranged on the top of the sealing cover, a collecting cover is arranged on the bottom of the air pump, a filter element is embedded in the collecting cover, and the output end of the air pump passes through the sealing cover and is connected with the collecting cover.

[0014] The beneficial effect of adopting the above further scheme is: after the concrete, mortar and other materials are mixed, the air pump is turned on to drive the air through the filter element into the collection cover, and then blown out into the drum through the collection cover, thereby accelerating the precipitation of internal dust and avoiding the situation where some dust has not settled after the cover is opened, causing dust to be raised and polluting the operating environment.

[0015] As a preferred embodiment, an auxiliary support frame is provided at one end of the mounting base plate, a support frame is provided at the other end of the mounting base plate, a damping member is provided inside the support frame, and an auxiliary support plate is provided on the top of the damping member. A first drive motor is provided on the rotating seat, and an output end of the first drive motor is connected to the equipment frame.

[0016] The beneficial effect of adopting the above further scheme is: the bottom of the cylinder in a vertical state is auxiliary supported by the design of an auxiliary support plate. Since the cylinder is filled with concrete, mortar and other materials, the overall weight of the cylinder is heavy. At this time, the damping member is used to reduce the impact force when the cylinder falls. The bottom of the equipment frame is further auxiliary supported by the auxiliary support frame to prevent the equipment frame from being suspended in the air and causing the drive assembly to tilt when the cylinder rotates.

[0017] As a preferred implementation, a second driving motor is disposed on the driving frame, and an output end of the second driving motor is connected to a driving gear.

At this time, the first drive motor is controlled to drive the equipment frame to flip, so that the equipment frame contacts the surface of the auxiliary support frame. Further, the second drive motor is turned on to drive the driving gear to rotate, so that the barrel is flipped under the action of the driving gear and the auxiliary gear. At this time, the concrete, mortar and other materials inside the barrel are stirred, tumbled and mixed under the action of the flip plate and the lifting plate, thereby reducing the dust raised during mixing.

[0021] 2. In the utility model, through the design of the air pump, after the concrete, mortar and other materials are mixed, the air pump is turned on to drive the air through the filter element into the collecting cover, and then blown into the drum through the collecting cover, accelerating the precipitation of internal dust, avoiding the situation where some dust has not settled after the cover is opened, causing dust to be raised and polluting the operating environment, thereby improving the practicality of the device.

[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] like Figure 1-5As shown, the utility model provides a technical solution: a dust removal mechanism, including a mounting base 1, a rotating seat 12 is arranged on the top of the mounting base 1, a driving assembly 2 is rotatably connected to the rotating seat 12, a roller assembly 3 is arranged on one side of the driving assembly 2, and a sealing cover 4 is arranged at the top opening of the roller assembly 3; the driving assembly 2 includes an equipment frame 29, the equipment frame 29 is rotatably connected to the rotating seat 12, one end of the equipment frame 29 is rotatably connected to the second connecting member 28, the other end of the equipment frame 29 is slidably connected to the first connecting member 24, and the second A connecting rod 23 is provided between the connecting member 28 and the first connecting member 24, a driving frame 26 is provided at one end of the connecting rod 23 close to the second connecting member 28, a driving gear 271 is rotatably connected to the driving frame 26, and auxiliary gears 27 are rotatably connected to both sides of the driving gear 271 on the driving frame 26, and a limiting frame 21 is provided at the other end of the equipment frame 29, a limiting roller 22 is rotatably connected to the limiting frame 21, a second driving motor 25 is provided on the driving frame 26, and a second The output end of the driving motor 25 is connected to the driving gear 271, and the inner center of the drum assembly 3 is rotatably connected with a flip plate 33. The inner wall of the cylinder 31 is provided with a lifting plate 34, and there are three lifting plates 34 in total, and the three lifting plates 34 are distributed in a ring shape, and the angles between two adjacent lifting plates 34 are equal. Compared with the open-type mixing barrel, the closed type is adopted, which can effectively reduce the dust raised when the concrete, mortar and other materials are mixed. After placing the concrete, mortar and other materials in the cylinder 31, the sealing cover 4 is installed on the cylinder 31, and at this time, the control installation base plate 1 limit frame 21 drives the equipment frame 29 to flip, so that the equipment frame 29 contacts the surface of the auxiliary support frame 11, and further, the second driving motor 25 is turned on to drive the driving gear 271 to rotate, so that the cylinder 31 is flipped under the action of the driving gear 271 and the auxiliary gear 27, and at this time, the concrete, mortar and other materials in the cylinder 31 are stirred, rolled and mixed under the action of the flip plate 33 and the lifting plate 34, which solves the technical problem of dust when the mixing barrel is in use.

[0034] Further, such as Figure 3 - Figure 4 As shown: an air pump 41 is arranged on the top of the sealing cover 4, a collecting cover 43 is arranged on the bottom of the air pump 41, a filter element 42 is embedded in the collecting cover 43, and the output end of the air pump 41 passes through the sealing cover 4 and is connected with the collecting cover 43.

[0035] The above solution also has the problem that the cylinder 31 may be displaced during stirring and may be separated from the limiting frame 21.

Since the cylinder 31 is filled with concrete, mortar and other materials, the overall weight of the cylinder 31 is heavy. At this time, the damping member 14 is used to reduce the impact force when the cylinder 31 falls, and the auxiliary support frame 11 is further used to provide auxiliary support for the bottom of the equipment frame 29 to prevent the equipment frame 29 from being suspended in the air and causing the drive assembly 2 to tilt when the cylinder 31 rotates.

[0037] Working principle:

[0038] like Figure 1-5 As shown, first, the installation base plate 1 is placed in the specified position. At this time, the cylinder 31 is in a vertical state. Concrete mortar and other materials are put into the cylinder 31. After the feeding is completed, the sealing cover 4 is installed on the cylinder 31. At this time, the first drive motor 121 is turned on to drive the equipment frame 29 to flip, so that the equipment frame 29 contacts the surface of the auxiliary support frame 11, and further the second drive motor 25 is turned on to drive the drive gear 271 to rotate, so that the cylinder 31 is flipped under the action of the drive gear 271 and the auxiliary gear 27. At this time, the concrete, mortar and other materials inside the cylinder 31 are stirred, tumbled and mixed under the action of the flip plate 33 and the lifting plate 34. After the mixing is completed, the first drive motor 121 is turned on to drive the equipment frame 29 to flip to a vertical state, and the air pump 41 is turned on to drive the air to pass through the filter element 42 and then enter the collecting cover 43, and then blown into the drum through the collecting cover 43, so as to accelerate the precipitation of internal dust and avoid the dust being raised after the cover is opened because some dust has not yet settled.

[0039] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms.
