Description

Technical Field

[0001] This utility model relates to the field of coal bunker fabrication technology, and in particular to a fully enclosed rotary fabrication machine. Background Technology

[0002] Coal bunker laying requires laying equipment, and Chinese Patent Application No. 202420860373.5 discloses a coal bunker laying system, including: a first belt conveyor located on a first platform; a second belt conveyor located on a second platform, the first platform being higher than the second platform, the second belt conveyor being movable on the second platform, the first belt conveyor receiving coal powder through an inlet and feeding the coal powder into the second belt conveyor through a chute located at the end, the second belt conveyor feeding the coal powder into the coal bunker located below the second platform through an outlet; and a bearing installed at a position on the second platform corresponding to the inlet of the coal bunker below, the inner ring of the bearing being fixed to the second platform, the outer ring of the bearing being able to rotate under the drive of a motor; an intermediate flexible hose section, the intermediate flexible hose section being a flexible hose fixed to the outer ring of the bearing; and an end bend, the end bend being a 90-degree rigid bend, the end bend being located at the end of the intermediate flexible hose section.

[0003] While the aforementioned technology achieves a certain degree of uniform material spreading through the rotatable end bend, in actual use, the simple tubular component, compared to the large coal bunker, still results in the point-like coal powder forming a cone-shaped accumulation within the bunker, albeit with an annular upper end. Furthermore, the end bend lacks a corresponding sealing component, causing the boiling powder to flow back into the end bend after material distribution. Therefore, to address these technical shortcomings, we propose a fully enclosed rotary material distributor. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a fully enclosed rotary fabric distribution machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A fully enclosed rotary concrete placing machine includes a coal bunker body. A protective cover is installed on the upper end of the coal bunker body. A guide bucket is installed on the upper side of the protective cover. A rotating shaft is rotatably provided on the inner side of the protective cover. Several plate-shaped sealing plates are provided on the outer ring surface of the rotating shaft. The outer ring surface of the sealing plates is attached to the inner wall of the protective cover. The lower side of the protective cover is located inside the coal bunker body and is in an open state. One end of the rotating shaft extends to the outside of the protective cover and is equipped with a magnetic suction plate. A matching mounting seat is installed on the outer side of the protective cover corresponding to the magnetic suction plate. An electromagnet is installed on the side of the mounting seat corresponding to the magnetic suction plate.

[0007] Preferably, the magnetic plate is strip-shaped, and the number of electromagnets is two.

[0008] Preferably, the end of the rotating shaft away from the mounting base extends to the outside of the protective cover and is fitted with a force-applying plate, the two ends of which are shovel-shaped.

[0009] Preferably, the front side of the outer surface of the protective cover is provided with a mounting groove, and an observation window is installed on the protective cover through the mounting groove.

[0010] Preferably, the sealing plate has an internal cavity and an outer surface that is smooth.

[0011] Preferably, the cavity of the sealing plate is provided with a plurality of reinforcing plates, which are evenly placed.

[0012] Preferably, the upper end of the guide bucket is cylindrical, and the lower end of the guide bucket is rectangular.

[0013] The fully enclosed rotary fabric distribution machine proposed in this utility model has the following advantages:

[0014] 1. In this utility model, the material is first temporarily stored at the sealing plate, and then enters the main body of the coal bunker through the rotating sealing plate. Compared with the traditional solution, the material descent distance is shortened, thereby reducing material splashing. At the same time, when the material inside the main body of the coal bunker accumulates to the top, the rotating sealing plate smooths the top of the material inside the main body of the coal bunker, so that the internal space of the main body of the coal bunker can be fully utilized. In addition, when the material inside the main body of the coal bunker accumulates too high and the sealing plate cannot rotate, the non-rotating sealing plate automatically seals the inside of the protective cover, so that subsequent material cannot flow into the main body of the coal bunker from the guide hopper. That is, the sealing plate has an automatic feeding effect, and it also prevents the flying powder inside the main body of the coal bunker from flowing back to the outside. Therefore, this solution has better sealing performance compared with the traditional solution.

[0015] 2. In this invention, because the magnetic suction plate is strip-shaped, when the electromagnet attracts the magnetic suction plate, the two electromagnets can attract and fix both ends of the magnetic suction plate, making it less likely for the magnetic suction plate to fall off the electromagnet's attraction, and making the rotation of the rotating shaft easier to control. The force plate allows personnel to easily determine from the outside whether the rotating shaft can rotate normally, i.e., whether the sealing plate is properly discharging materials falling inside the protective cover in batches. Thus, when material supply is not needed, the rotating shaft can be fixed by the attraction of the electromagnet, preventing the sealing plate from rotating. The observation window allows personnel to easily observe the situation inside the protective cover and to maintain the internal components from the top, thereby ensuring the normal operation of the equipment.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example 1

[0024] Reference Figure 1-5 A fully enclosed rotary concrete placing machine includes a coal bunker body 1, a protective cover 2 installed at the upper end of the coal bunker body 1, a guide bucket 3 installed on the upper side of the protective cover 2, a rotating shaft 4 rotatably installed inside the protective cover 2, a plurality of plate-shaped sealing plates 5 provided on the outer ring surface of the rotating shaft 4, the outer ring surface of the sealing plates 5 adhering to the inner wall of the protective cover 2, the lower side of the protective cover 2 located inside the coal bunker body 1 and in an open state, one end of the rotating shaft 4 extending to the outside of the protective cover 2 and a magnetic suction plate 6 installed thereon, a matching mounting seat 7 installed on the outer side of the protective cover 2 corresponding to the magnetic suction plate 6, and an electromagnet installed on the side of the mounting seat 7 corresponding to the magnetic suction plate 6.

[0025] Example 2

[0026] Reference Figure 1-5 While all other parts are the same as in Example 1, the difference between this example and Example 1 is that:

[0027] The magnetic suction plate 6 is strip-shaped, and there are two electromagnets. Because the magnetic suction plate 6 is strip-shaped, when the electromagnets attract the magnetic suction plate 6, the two electromagnets can attract and fix the two ends of the magnetic suction plate 6, making it less likely for the magnetic suction plate 6 to fall off the attraction of the electromagnets, and making the rotation of the rotating shaft 4 easier to control. The end of the rotating shaft 4 away from the mounting base 7 extends to the outside of the protective cover 2 and is equipped with a force plate 8. The two ends of the force plate 8 are shovel-shaped. The setting of the force plate 8 makes it easy for personnel to judge from the outside whether the rotating shaft 4 can rotate normally, that is, whether the sealing plate 5 can properly distribute the materials falling inside the protective cover 2 in batches. The front side of the outer surface of the protective cover 2 is provided with a mounting groove, and the protective cover 2 is equipped with an observation window 9 through the mounting groove. The setting of the observation window 9 makes it easy for personnel to observe the internal condition of the protective cover 2, and also makes it easy for personnel to maintain the internal components of the protective cover 2 from the top, thereby ensuring the normal operation of the equipment.

[0028] The sealing plate 5 has a cavity 11 inside and a smooth outer surface. The cavity 11 reduces the weight of the sealing plate 5, making it easier for the coal powder to rotate when it falls, thus facilitating material distribution. The smooth outer surface also allows the coal powder to fall more smoothly along the surface of the sealing plate 5, preventing it from sticking. Several reinforcing plates 10 are evenly placed inside the cavity 11 of the sealing plate 5, preventing deformation of the area with the cavity 11 and ensuring normal operation. The guide bucket 3 has a cylindrical upper end and a rectangular lower end. This shape facilitates the entry of material into the protective cover 2.

[0029] Operating principle and advantages: During use, the upper end of the guide bucket 3 is connected to the external material supply facility, that is, the coal powder is placed inside the guide bucket 3. Since the outer surface of the sealing plate 5 is attached to the inner wall of the protective cover 2, the rotating shaft 4 divides the space on the upper side of the protective cover 2 through each sealing plate 5. That is, the space inside the protective cover 2 is divided into several material storage spaces by the sealing plates 5, that is, the space between adjacent sealing plates 5 is the material storage space.

[0030] Therefore, in the above process, the material directly enters the interior of the protective cover 2, that is, the material enters the material storage space directly opposite the guide hopper 3. Subsequently, as the material enters, it pushes the sealing plate 5 to rotate downwards. That is, this material storage space, which has collected the material, flips from top to bottom into the coal bunker body 1, while the originally empty material storage space is simultaneously flipped into the protective cover 2 to catch the falling material. Thus, through the cooperation of the above-mentioned components, when the material is discharged, it is first temporarily stored at the sealing plate 5, and then enters the coal bunker body 1 through the flipped sealing plate 5. Compared with the traditional solution, the material descent distance is shortened. This reduces material splashing. Simultaneously, when material accumulates to the top inside the main body 1 of the coal bunker, the rotating sealing plate 5 smooths the material at the top, allowing full utilization of the internal space. Furthermore, if the material accumulation inside the main body 1 is too high, preventing the sealing plate 5 from rotating, it automatically seals the inside of the protective cover 2, preventing subsequent material from flowing into the main body 1 from the guide hopper 3. In other words, the sealing plate 5 has an automatic feeding effect, and also prevents the flying powder inside the main body 1 from flowing back to the outside. Therefore, this solution has better sealing performance compared to traditional solutions.

[0031] It should be further explained that, because the magnetic plate 6 is strip-shaped, when the electromagnet attracts the magnetic plate 6, the two electromagnets can attract and fix the two ends of the magnetic plate 6, making it less likely for the magnetic plate 6 to fall off the electromagnet's attraction, and making the rotation of the rotating shaft 4 easier to control; the setting of the force plate 8 allows personnel to easily determine from the outside whether the rotating shaft 4 can rotate normally, that is, whether the sealing plate 5 is properly discharging the material falling inside the protective cover 2 in batches. Thus, when material supply is not required, the rotating shaft 4 can be fixed by the attraction of the electromagnet, so that the sealing plate 5 cannot rotate; the setting of the observation window 9 allows personnel to... On the one hand, it facilitates the observation of the internal condition of the protective cover 2, and on the other hand, it facilitates the maintenance of the internal components of the protective cover 2 from the top, thereby ensuring the normal operation of the equipment. The setting of the cavity 11 reduces the weight of the sealing plate 5, making it easier to rotate the sealing plate 5 when the coal powder falls, thus facilitating the material distribution. Moreover, since the outer surface of the sealing plate 5 is a smooth surface, the coal powder can fall more smoothly along the surface of the sealing plate 5, preventing the coal powder from sticking to the surface of the sealing plate 5. The setting of the reinforcing plate 10 makes the part of the sealing plate 5 with the cavity 11 less prone to deformation, thus ensuring the normal operation of the sealing plate 5.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
