Description

Technical Field

[0001] This utility model relates to the technical field of port bulk cargo loading and unloading machinery and equipment, and in particular to a sealing device for a ground belt conveyor covering a chain bucket unloader. Background Technology

[0002] With the development of bulk cargo handling terminal technology, chain bucket continuous unloaders have emerged. This technology features high production efficiency and good environmental performance, which in turn has led to the development of related devices such as plow-type guide chutes to achieve effective sealing between the main machine and the terminal belt conveyor.

[0003] In related technologies, a plow-shaped guide chute is used to plow open the ground conveyor belt cover when the chain bucket unloader moves, and a pressure roller is set at each end of the guide chute to press the cover belt tightly so that it is completely closed.

[0004] However, the plow-shaped guide chute described above has a problem with the right-side pressure roller and right-side cover belt not closing properly, which causes a large amount of dust to overflow during the operation of the chain bucket unloader, seriously affecting the environmental performance of the equipment. Utility Model Content

[0005] In response to the shortcomings of the existing production technology, the applicant provides a sealing device for the ground belt conveyor cover of a chain bucket unloader, which has the advantages of reasonable structure, low cost, good sealing effect and high stability.

[0006] The technical solution adopted in this utility model is as follows: A sealing device for a ground conveyor belt cover of a chain bucket unloader includes a plow-shaped guide chute. In the horizontal direction, a single pressure roller is arranged on the left side of the plow-shaped guide chute, and a pressure roller assembly is arranged on the right side. The pressure roller assembly is configured to include at least two pressure rollers arranged in a horizontal direction; The pressure roller assembly is fixedly connected to the bottom beam of the electrical room and is in close contact with the upper surface of the conveyor belt cover on the right side of the plow-shaped guide chute; It also includes a sealing cover assembly, which is fixed to the right side of the plow-shaped feed chute, forming a sealed space above the conveyor belt cover on the right side.

[0007] As a further improvement to the above technical solution: In one embodiment, the pressure roller assembly includes a first pressure roller mechanism and a second pressure roller mechanism arranged sequentially in a horizontal direction on the right side of the plow-shaped guide chute.

[0008] In one embodiment, the first pressure roller mechanism includes a first support, a first connecting rod, and a first pressure roller; the first support is fixedly connected to the bottom beam of the electrical room; one end of the first connecting rod is connected to the first support via a pin; and the first pressure roller is mounted on the other end of the first connecting rod.

[0009] In one embodiment, the first pressure roller mechanism further includes a first counterweight block disposed on the first connecting rod.

[0010] In one embodiment, the second pressure roller mechanism includes a second support, a second connecting rod, and a second pressure roller; the second support is fixedly connected to the bracket of the first pressure roller; one end of the second connecting rod is connected to the second support via a pin, and the second connecting rod extends in the horizontal direction; the second pressure roller is mounted on the other end of the second connecting rod.

[0011] In one embodiment, the second pressure roller mechanism further includes a second counterweight block disposed on the second connecting rod.

[0012] In one embodiment, the sealing cover assembly includes a bracket, a folded edge plate, and a rubber skirt plate; wherein the bracket is welded from square steel; the folded edge plate is welded to the bracket; and the rubber skirt plate is installed around the bottom of the folded edge plate and fastened with bolts.

[0013] In one embodiment, the side of the sealing cover assembly that intersects with the plow-shaped feed chute is not fitted with a rubber skirt.

[0014] In one embodiment, the left side of the plow-shaped guide trough is connected to the single pressure roller connecting rod via a single pressure roller support, and a single pressure roller is configured at the end of the single pressure roller connecting rod away from the single pressure roller support.

[0015] The beneficial effects of this utility model are as follows: This utility model has a compact structure. By working together with the pressure roller assembly and the sealing cover assembly, the pressure roller assembly is mainly responsible for physically pressing the right-side cover belt to ensure that its main body is closed; while the sealing cover assembly forms a sealed space in the right-side area, further effectively blocking the channel for dust to overflow, fundamentally improving the environmental performance of the equipment.

[0016] This utility model also has the following advantages: The pressure roller assembly of this utility model adopts a structure combining levers and counterweights. It is connected by a connecting rod and a pin, allowing the pressure roller to float within a certain range. By configuring an adjustable counterweight on the connecting rod, it can provide continuous, stable and precisely controllable downward pressure to the pressure roller, ensuring that the pressure roller is always in complete contact with the cover belt. This avoids problems such as incomplete closure or accelerated wear caused by insufficient or excessive pressure, and significantly improves the stability and reliability of the seal.

[0017] Instead of simply increasing the size of the original pressure roller, this invention extends a second independent pressure roller mechanism onto the support of the first pressure roller on the right side, forming a progressive compression and sealing area. This brings the potentially unsealed sections into the effective compression range, precisely reinforcing the seal of the most leak-prone dust points. Attached Figure Description

[0027] Furthermore, the accompanying drawings are not drawn to a 1:1 scale, and the relative dimensions of the components are shown in the drawings only as examples and not necessarily to actual scale.

[0028] like Figures 1-3 The accompanying drawing shows a schematic diagram of the structural state of a sealing device for a ground belt conveyor covering a chain bucket unloader according to an embodiment of the present invention; for ease of description, the drawing only shows the structure related to the embodiment of the present invention.

[0029] This application provides a sealing device for the cover belt of a ground conveyor for a chain bucket unloader, which is arranged around a plow-shaped guide chute 100. The left side of the plow-shaped guide chute 100 is pressed by a conventional single pressure roller 3, while the right side of the plow-shaped guide chute 100 is provided with a sealing system including a pressure roller assembly 2 and a sealing cover assembly 1. The pressure roller assembly 2 is fixedly installed on the bottom beam 200 of the electrical room, and the sealing cover assembly 1 is fixedly installed on the right side of the plow-shaped guide chute 100.

[0030] See Figure 2 The pressure roller assembly 2 includes a first pressure roller mechanism and a second pressure roller mechanism; The first pressure roller mechanism includes a first support 21, a first connecting rod 22, a first counterweight 23, and a first pressure roller 24; The first support 21 is fixed to the bottom beam 200 of the electrical room by welding. One end of the first connecting rod 22 is hinged to the first support 21 via a pin; The first pressure roller 24 is installed at the other end of the first connecting rod 22 away from the first support 21; Furthermore, a first counterweight 23 is also installed on the first connecting rod 22. By adjusting the mass of the first counterweight 23, the pressure applied by the first pressure roller 24 to the conveyor belt can be precisely controlled to ensure that the conveyor belt is effectively flattened and closed.

[0031] The second pressure roller mechanism extends from the first pressure roller mechanism and includes a second support 25, a second connecting rod 26, a second counterweight 27, and a second pressure roller 28.

[0032] The second support 25 is directly fixedly connected to the bracket of the first pressure roller 24; One end of the second link 26 is hinged to the second support 25 by a pin, and the design of the second link 26 makes it extend outward in the horizontal direction; The second pressure roller 28 is installed at the end of the second connecting rod 26 away from the second support 25.

[0033] Similarly, a second counterweight 27 is configured on the second connecting rod 26 to provide a stable and adjustable clamping force for the second pressure roller 28. This two-stage progressive pressure roller layout ensures that the covering strip in the wider area on the right side of the plow-shaped guide trough 100 can be reliably clamped, eliminating the sealing blind spot that is prone to occur on the right side of a single pressure roller.

[0034] like Figure 3 The diagram shown is a structural schematic of the sealing cover assembly 1; the sealing cover assembly 1 is mainly composed of a bracket 11, a folded edge plate 12 and a rubber skirt plate 13; The bracket 11, which serves as the skeleton of the entire component, is welded from square steel and provides the main structural support.

[0035] The shape of the folded edge plate 12 matches the size of the bracket 11, and the two are firmly connected together by welding to form an inverted U-shaped cover structure; Flexible rubber skirts 13 are installed around the bottom of the folded edge plate 12 by bolts.

[0036] These rubber skirts 13 can effectively fit the surface of the equipment below, forming a more complete sealed dustproof space.

[0037] It should be noted that the rubber skirt 13 is not installed on the side of the sealing cover assembly 1 that is adjacent to the plow-shaped guide chute 100 itself.

[0038] In practical applications, the working principle of this utility model is as follows: When the chain bucket unloader is working, the pressure roller assembly 2 on its right side applies continuous and uniform pressure to the conveyor belt cover belt through two pressure rollers with counterweights (first pressure roller 24 and second pressure roller 28), so that it is tightly closed. At the same time, the sealing cover assembly 1 fixed on the plow-shaped guide trough 100 covers the pressure roller's working area and its rear, forming a secondary sealing space together with the rubber skirt 13, effectively capturing and blocking dust that may escape. The single pressure roller 3 on the left performs the basic sealing function.

[0039] The sealing device for the ground belt conveyor cover of the chain bucket unloader of this utility model achieves efficient, stable and environmentally friendly sealing without the need for external power through the ingenious combination of mechanical structure and counterweight.

[0040] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0041] The embodiments described above merely illustrate the implementation of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
